[Maria-developers] commit performance when the binlog is enabled
by MARK CALLAGHAN 30 Dec '09

30 Dec '09

InnoDB fixed group commit in the InnoDB plugin. This performs as expected when the binlog is disabled. This does not perform as I expect when the binlog is enabled. Is this a problem for PBXT? The problems for InnoDB are: 1) commit is serialized on the binlog write/fsync 2) row locks are not released until the commit step of XA prepare/commit 3) per-table auto inc locks not released until the commit step of XA I think that 2) and 3) can be fixed without significant changes. They cause a lot of convoys today for high-throughput OLTP -- too many connections needlessly wait on row locks and the per-table auto-inc lock. Doing the binlog fsync one connection at a time also causes a lot of convoys. This makes MySQL much slower than it should be for some workloads even with battery backed RAID write caches. Problem 1) occurs because: * there is no group commit for the binlog fsync * InnoDB locks prepare_commit_mutex in the prepare step Even if there were group commit for the binlog fsync, it would be useless for InnoDB because prepare_commit_mutex is locked in the prepare step and not unlocked until the commit step and the binlog write/fsync is done between these two steps. There is a MySQL worklog for this (4007) that: * doesn't intend to add group commit for the binlog fsync * doesn't mention the problem of prepare_commit_mutex I have started to work on this, but don't have any code to share yet. Pseudo-code for commit with the InnoDB plugin when the binlog is enabled: ha_commit_trans() * ht->prepare() == innobase_xa_prepare() o trx_prepare_for_mysql(trx) + force to disk the trx log buffer for all changes from this trx + fsync done here, group prepare may amortize that o lock prepare_commit_mutex * tc_log->log_xid(thd, xid) o writes SQL to binlog, XID to binlog, optionally fsync binlog * ha_commit_one_phase() o ht->commit() == innobase_commit() + innobase_commit_low(() # write commit record to trx log buffer, release locks from this trx # for auto-commit statements, the per-table auto-inc lock is released here + unlock prepare_commit_mutex + trx_commit_complete_for_mysql() # force to disk the trx log buffer including commit record for this trx # fsync done here, group commit may amortize that -- Mark Callaghan mdcallag(a)gmail.com

[Maria-developers] 2PC between two engines + binlog
by Arjen Lentz 29 Dec '09

29 Dec '09

Hi Hakan, all With PBXT and the latest merge, this should now technically be enabled (again). That is, a transaction should be consistent between InnoDB+PBXT +binlog, that is either all or none should commit. But as I understand, when this was last tried with Falcon it went kaboom in MySQL, so likely there are some bugs. I think it would be good to at least create/enable some tests for this, then we can see what the exact code status is, and hopefully get it all working as well. Right now I don't think anybody really expects something like this to work, but in theory it should work so presumptions *may* be made (I know this sentence appears kinda contradictory, hope it makes sense anyhow ;-). Thus it's important for us to know what happens, so that we can tell people "don't do this now, please track bug #", or "please try this". Thanks Cheers, Arjen. -- Arjen Lentz, Exec.Director @ Open Query (http://openquery.com) Exceptional Services for MySQL at a fixed budget.

Before, two plans were competing, and that was addressed by using --sorted_result on the EXPLAIN output because they were different only in join order. Now we've got a 3rd plan which differs with "Using where" and that doesn't work anymore. - This patch fixes it by removing 'Using where' from EXPLAIN output.

Reverted wrong code in sql_table.cc for how ROW_FORMAT is used. Todo before joining with main 5.1 tree: - Join test fails (Igor to investigate) - mysql-test-run shows warnings from tests; Some suppression rule is not working (Kristian to investiage) - Run through

#At lp:maria 2778 knielsen(a)knielsen-hq.org 2009-12-22 [merge] Merge fix for PBXT running inside embedded server (MBug#439889). Also some small fixes to make the PBXT testsuite work in --embedded. renamed: mysql-test/suite/pbxt/t/load_unique_error1.inc => mysql-test/std_data/pbxt_load_unique_error1.inc modified: config/ac-macros/plugins.m4 mysql-test/suite/pbxt/r/pbxt_bugs.result mysql-test/suite/pbxt/t/pbxt_bugs.test mysql-test/suite/pbxt/t/pbxt_locking.test mysql-test/suite/pbxt/t/pbxt_transactions.test mysql-test/suite/pbxt/t/ps_1general.test sql/sql_plugin.cc storage/pbxt/plug.in storage/pbxt/src/Makefile.am storage/pbxt/src/ha_pbxt.cc storage/pbxt/src/table_xt.cc storage/pbxt/src/thread_xt.cc storage/pbxt/src/trace_xt.cc per-file messages: config/ac-macros/plugins.m4 MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS macro extended to support multiple files. mysql-test/std_data/pbxt_load_unique_error1.inc Move file to be accessible also for testing embedded server. mysql-test/suite/pbxt/r/pbxt_bugs.result Fix LOAD DATA LOCAL INFILE path so it works also for testing embedded server. mysql-test/suite/pbxt/t/pbxt_bugs.test Fix LOAD DATA LOCAL INFILE path so it works also for testing embedded server. mysql-test/suite/pbxt/t/pbxt_locking.test Disable for embedded, as it needs SHOW PROCESSLIST functionality not available there. mysql-test/suite/pbxt/t/pbxt_transactions.test Disable test for embedded, as it needs ability to connect from outside (mysqldump). mysql-test/suite/pbxt/t/ps_1general.test Fix replace_result for new mysql-test-run.pl. sql/sql_plugin.cc Remove hack that disables PBXT in embedded. storage/pbxt/plug.in Fix crash in PBXT in embedded server. storage/pbxt/src/Makefile.am Remove not needed CFLAGS/CXXFLAGS (they cause autotools to generate different object names, which in turn cause the MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS replacement of object files inside library files not to work). storage/pbxt/src/ha_pbxt.cc Ugly hack to allow more threads in embedded server (need a better fix I think). storage/pbxt/src/table_xt.cc Use stderr for logging not stdout (prevent spamming --embedded test suite output with stray messages). storage/pbxt/src/thread_xt.cc Use stderr for logging not stdout (prevent spamming --embedded test suite output with stray messages). storage/pbxt/src/trace_xt.cc Use stderr for logging not stdout (prevent spamming --embedded test suite output with stray messages). === modified file 'config/ac-macros/plugins.m4' --- a/config/ac-macros/plugins.m4 2009-04-25 10:05:32 +0000 +++ b/config/ac-macros/plugins.m4 2009-12-22 10:33:20 +0000 @@ -267,7 +267,6 @@ dnl we have to recompile these modules dnl to compile server parts with the different #defines dnl Normally it happens when we compile the embedded server dnl Thus one should mark such files in his handler using this macro -dnl (currently only one such a file per plugin is supported) dnl dnl --------------------------------------------------------------------------- @@ -463,11 +462,13 @@ dnl Although this is "pretty", it breaks mysql_plugin_defs="$mysql_plugin_defs, [builtin_]$2[_plugin]" [with_plugin_]$2=yes AC_MSG_RESULT([yes]) - m4_ifdef([$11],[ - condition_dependent_plugin_modules="$condition_dependent_plugin_modules m4_bregexp($11, [[^/]+$], [\&])" - condition_dependent_plugin_objects="$condition_dependent_plugin_objects m4_bregexp($11, [[^/]+\.], [\&o])" - condition_dependent_plugin_links="$condition_dependent_plugin_links $6/$11" - condition_dependent_plugin_includes="$condition_dependent_plugin_includes -I[\$(top_srcdir)]/$6/m4_bregexp($11, [^.+[/$]], [\&])" + m4_ifdef([$11], [ + m4_foreach([plugin], [$11], [ + condition_dependent_plugin_modules="$condition_dependent_plugin_modules m4_bregexp(plugin, [[^/]+$], [\&])" + condition_dependent_plugin_objects="$condition_dependent_plugin_objects m4_bregexp(plugin, [[^/]+\.], [\&o])" + condition_dependent_plugin_links="$condition_dependent_plugin_links $6/plugin" + condition_dependent_plugin_includes="$condition_dependent_plugin_includes -I[\$(top_srcdir)]/$6/m4_bregexp(plugin, [^.+[/$]], [\&])" + ]) ]) fi fi === renamed file 'mysql-test/suite/pbxt/t/load_unique_error1.inc' => 'mysql-test/std_data/pbxt_load_unique_error1.inc' === modified file 'mysql-test/suite/pbxt/r/pbxt_bugs.result' --- a/mysql-test/suite/pbxt/r/pbxt_bugs.result 2009-08-17 15:57:58 +0000 +++ b/mysql-test/suite/pbxt/r/pbxt_bugs.result 2009-12-22 10:33:20 +0000 @@ -1212,7 +1212,7 @@ c1 2147483647 DROP TABLE IF EXISTS t1;

Kristian, Sorry for making it seem like I wasn't adressing the group but I thought it was Arjen posing the question about build hosts. On a related note, I just got a netra 1u system I can put opensolaris on and configure. Do you have notes on configuring buildbot in addition to those found on your live journal site that you want me to follow?

Worked 2 hours and estimate 0 hours remain (original estimate increased by 2 hours). ------------------------------------------------------------ -=-=(View All Progress Notes, 12 total)=-=- http://askmonty.org/worklog/index.pl?tid=50&nolimit=1 DESCRIPTION: According to complaints in BUG#46640: 1. mysqlbinlog will emit a 5.0-incompatible "format description binlog statement" even when reading a binary log that was produced by 5.0. This will cause an error when one tires to apply mysqlbinlog output to a 5.0.x server. 2. When one executes a BINLOG statement (containing "format description binlog statement" or other events), this will cause subsequent statements run in the same session to be binlogged with the server id of the last event executed, not with the real server id. This can cause problems like infinite recursive application in a circular replication topology. This WL is to fix these issues. HIGH-LEVEL SPECIFICATION: First item ---------- AFAIU what needs to be done is: 1. record a source server version (it is in the first binlog event). 2. don't emit a BINLOG statement if the recorded version number is 5.0.x or below. and we'll get a 5.0-applicable binlog. Second item ----------- One question that one needs to sort out before disabling server_id change is why it was put there in the first place? Should it be always removed? First, the problem is not the format description log event. In fact all log events have their own value of server_id, and every event in the BINLOG statement is executed with its own id as server_id. It seems it was introduced deliberately in the patch for Bug#32407. This patch makes sql thread and BINLOG statement share code path for executing the binary event, even though the bug is really about something different (outputting format description event to allow proper execution of other BINLOG statements). Nevertheless, I think using the server_id in the events of a BINLOG statement is wrong: 1. It is different behaviour from executing normal statement-based events not written using BINLOG. 2. It causes the possibility for infinite cycle of replication in a cyclic replication setup, if the server ids in BINLOG are different from all other server ids in the cycle. 3. The functionality of applying events with original server id from the event is still available by pointing the slave thread to the binlog. The functionality of applying row-based binlog events with server id of the server executing the BINLOG statements is not otherwise available. In fact most of the code from the slave thread that is now also run when executing BINLOG statements is redundant, or does the wrong thing (like updating binlog position). Maybe there is a confusion on the purpose of the BINLOG statement. Is it to be able to apply row-based events manually to a server (mysqlbinlog|mysql)? Or is it to be able to simulate the effect of the slave sql thread? I think the former is the most important one. LOW-LEVEL DESIGN: I think the fix for point 2 is to replace the call to apply_event_and_update_pos() in mysql_client_binlog_statement() with a direct call to ev->apply_event(). However, I need to check two things to be sure this is correct: 1. The existing code does if (!ev->when) ev->when= my_time(0) Need to understand if this is needed/correct or not. 2. The existing code does ev->update_pos(). I think this is redundant for BINLOG statement (as it uses a fake rli structure), but I need to check to make sure. Once this is done, point 1 may no longer be needed. The user can use --base64-output=never when applying the output to a 5.0 server, and omit that option when applying the output to a 5.1 server. There should be no need to omit the format description event in the output when other BINLOG statements for row events are present, as it no longer changes the server id. In fact the format description event is required to be able to execute other BINLOG statements, as its purpose is to define the binary format of the events contained in these statements. Alternatively, we could implement that if the format description event of the source binlog has server version < 5.1, and --base64-output=auto (default), then the format description event is omitted (and should any BINLOG statement be needed, unlikely as it is from a 5.0 server, we will need to throw an error). The binlog format version for 5.0 and 5.1 is actually the same, hence the need to look at server version to guess if the format description event can be omitted.

Outline of Annotate_rows event behavior +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Each Annotate_rows_log_event object has two private members describing the +corresponding query: + + char *m_query_txt; + uint m_query_len; + +When the object is created for writing to a binary log, this query is taken +from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix +as well as other implementation details): + + Annotate_rows_log_event(THD *thd) + { + m_query_txt = thd->query(); + m_query_len = thd->query_length(); + } + +When the object is read from a binary log, the query is taken from the buffer +containing the binary log representation of the event (this buffer is allocated +in Log_event object from which all Log events are derived): + + Annotate_rows_log_event(char *buf, uint event_len, + Format_description_log_event *desc) + { + m_query_len = event_len - desc->common_header_len; + m_query_txt = buf + desc->common_header_len; + } + +The events are written to the binary log by the Log_event::write() member +which calls virtual write_data_header() and write_data_body() members +("data header" and "post header" are synonym in replication terminology). +In our case, data header is empty and data body is just the query: + + bool write_data_body(IO_CACHE *file) + { + return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); + } + +Printing the event is just printing the query: + + void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) + { + my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); + } + +3. How Master writes Annotate_rows events to the binary log +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The event is written to the binary log just before the group of Table_map +events which precede corresponding Rows events (one query may generate +several Table map events in the binary log, but the corresponding +Annotate_rows event must be written only once before the first Table map +event; hence the boolean variable 'with_annotate' below): + + int write_locked_table_maps(THD *thd) + { ... + bool with_annotate= thd->variables.binlog_annotate_rows_events; + ... + for (uint i= 0; i < ... <number of tables> ...; ++i) + { ... + thd->binlog_write_table_map(table, ..., with_annotate); + with_annotate= 0; // write Annotate_event not more than once + ... + } + ... + } + + int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) + { ... + Table_map_log_event the_event(...); + ... + if (with_annotate) + { + Annotate_rows_log_event anno(this); + mysql_bin_log.write(&anno); + } + + mysql_bin_log.write(&the_event); + ... + } + +4. How slave treats replicate-annotate-rows-events option +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The replicate-annotate-rows-events option is treated just as the session +value of the binlog_annotate_rows_events variable for the slave IO and +SQL threads. This setting is done during initialization of these threads: + + pthread_handler_t handle_slave_io(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_IO); + ... + } + + pthread_handler_t handle_slave_sql(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_SQL); + ... + } + + int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) + { ... + thd->variables.binlog_annotate_rows_events= + opt_replicate_annotate_rows_events; + ... + } + +5. How slave IO thread requests Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +When requesting an event, the slave should inform the master whether +it should send Annotate_rows events or not. To that end we add a new +BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: + + #define BINLOG_DUMP_NON_BLOCK 1 + #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 + + pthread_handler_t handle_slave_io(void *arg) + { ... + request_dump(mysql, ...); + ... + } + + int request_dump(MYSQL* mysql, ...) + { ... + if (opt_log_slave_updates && + mi->io_thd->variables.binlog_annotate_rows_events) + binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; + ... + int2store(buf + 4, binlog_flags); + ... + simple_command(mysql, COM_BINLOG_DUMP, buf, ...); + ... + } + +6. How master executes the request +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + case COM_BINLOG_DUMP: + { ... + flags= uint2korr(packet + 4); + ... + mysql_binlog_send(thd, ..., flags); + ... + } + + void mysql_binlog_send(THD* thd, ..., ushort flags) + { ... + Log_event::read_log_event(&log, packet, ...); + ... + if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || + flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || + thd->server_id == 0 /* slave == mysqlbinlog */ ) + { + my_net_write(net, packet->ptr(), packet->length()); + } + ... + } + +7. How slave SQL thread processes Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The slave processes each recieved event by "applying" it, i.e. by +calling the Log_event::apply_event() function which in turn calls +the virtual do_apply_event() member specific for each type of the +event. + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev = next_event(rli); + ... + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + + int apply_event_and_update_pos(Log_event *ev, ...) + { ... + ev->apply_event(...); + ... + } + + int Log_event::apply_event(...) + { + return do_apply_event(...); + } + +What does it mean to "apply" an Annotate_rows event? It means to set current +thd query to that of the described by the event, i.e. to the query which +caused the subsequent Rows events (see "How Master writes Annotate_rows +events to the binary log" to follow what happens further when the subsequent +Rows events is applied): + + int Annotate_rows_log_event::do_apply_event(...) + { + thd->set_query(m_query_txt, m_query_len); + } + +NOTE. I am not sure, but possibly current values of thd->query and +thd->query_length should be saved before calling set_query() and to be +restored on the Annotate_rows_log_event object deletion. +Is it really needed ? + +After calling this do_apply_event() function we may not delete the +Annotate_rows_log_event object immediatedly (see exec_relay_log_event() +above) because thd->query now points to the string inside this object. +We may keep the pointer to this object in the Relay_log_info: + + class Relay_log_info + { + public: + ... + void set_annotate_event(Annotate_rows_log_event*); + Annotate_rows_log_event* get_annotate_event(); + void free_annotate_event(); + ... + private: + Annotate_rows_log_event* m_annotate_event; + }; + +When the saved Annotate_rows object may be deleted? When all corresponding +Rows events will be processed, i.e. before processing the first non-Rows +event (note that Annotate_rows object resides in the binary log *after* +the (possible) 'BEGIN' Query event which accompanies the rows events; note +also that this deletion is adjusted with the case when some or all +corresponding Rows events are filtered out by replicate filter rules): + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev= next_event(rli); + ... + if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) + rli->free_annotate_event(); + + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) + rli->set_annotate_event((Annotate_rows_log_event*) ev); + else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + +where + + #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ + (type) == WRITE_ROWS_EVENT || \ + (type) == UPDATE_ROWS_EVENT || \ + (type) == DELETE_ROWS_EVENT ) + +8. General remarks +~~~~~~~~~~~~~~~~~~ +Kristian noticed that introducing new log event type should be coordinated +somehow with MySQL/Sun: + + Kristian: The numeric code for this event must be assigned carefully. + It should be coordinated with MySQL/Sun, otherwise we can get into a + situation where MySQL uses the same numeric code for one event that + MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two + impossible. + Alex: I reserved about 20 numbers not to have possible conflicts + with MySQL. + Kristian: Still, I think it would be appropriate to send a polite email + to internals(a)lists.mysql.com about this and suggesting to reserve the + event number. + +Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT +flag taking into account that MySQL/Sun may also introduce a flag with the +same value to be used in the request_dump-mysql_binlog_send interface. +But this is mainly the question of merging: if a conflict concerning this +flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value +(this does not require additional changes in the code). -=-=(Alexi - Sat, 19 Dec 2009, 15:41)=-=- High-Level Specification modified. --- /tmp/wklog.47.old.14545 2009-12-19 15:41:21.000000000 +0200 +++ /tmp/wklog.47.new.14545 2009-12-19 15:41:21.000000000 +0200 @@ -1,122 +1,107 @@ -First suggestion: - -> I think for this we would actually need a new binlog event type -> (Comment_log_event?).

(See example in the "mysqlbinlog output" section below.) 2. Server option: --binlog-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Tells the master to write Annotate_rows events to the binary log. * Variable Name: binlog_annotate_rows_events * Scope: Global & Session * Access Type: Dynamic * Data Type: bool * Default Value: OFF NOTE. Session values allows to annotate only some selected statements: ... SET SESSION binlog_annotate_rows_events=ON; ... statements to be annotated ... SET SESSION binlog_annotate_rows_events=OFF; ... statements not to be annotated ... 3. Server option: --replicate-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Tells the slave to reproduce Annotate_rows events recieved from the master in its own binary log (sensible only in pair with log-slave-updates option). * Variable Name: replicate_annotate_rows_events * Scope: Global * Access Type: Read only * Data Type: bool * Default Value: OFF NOTE. Why do we additionally need this 'replicate' option? Why not to make the slave to reproduce this events when its binlog-annotate-rows-events global value is ON? Well, because, for example, we may want to configure the slave which should reproduce Annotate_rows events but has global binlog-annotate-rows-events = OFF meaning this to be the default value for the client threads (see also "How slave treats replicate-annotate-rows-events option" in LLD part). 4. mysqlbinlog option: --print-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ With this option, mysqlbinlog prints the content of Annotate_rows events (if the binary log does contain them). Without this option (i.e. by default), mysqlbinlog skips Annotate_rows events. 5. mysqlbinlog output ~~~~~~~~~~~~~~~~~~~~~ With --print-annotate-rows-events, mysqlbinlog outputs Annotate_rows events in a form like this: ... # at 1646 #091219 12:45:26 server id 100 end_log_pos 1714 Query thread_id=1 exec_time=0 error_code=0 SET TIMESTAMP=1261215926/*!*/; BEGIN /*!*/; # at 1714 # at 1812 # at 1853 # at 1894 # at 1938 #091219 12:45:26 server id 100 end_log_pos 1812 Query: `DELETE t1, t2 FROM t1 INNER JOIN t2 INNER JOIN t3 WHERE t1.a=t2.a AND t2.a=t3.a` #091219 12:45:26 server id 100 end_log_pos 1853 Table_map: `test`.`t1` mapped to number 16 #091219 12:45:26 server id 100 end_log_pos 1894 Table_map: `test`.`t2` mapped to number 17 #091219 12:45:26 server id 100 end_log_pos 1938 Delete_rows: table id 16 #091219 12:45:26 server id 100 end_log_pos 1982 Delete_rows: table id 17 flags: STMT_END_F ...

How slave SQL thread processes Annotate_rows events 8. General remarks 1. Annotate_rows event number ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To avoid possible event numbers conflict with MySQL/Sun, we leave a gap between the last MySQL event number and the Annotate_rows event number: enum Log_event_type { ... INCIDENT_EVENT= 26, // New MySQL event numbers are to be added here MYSQL_EVENTS_END, MARIA_EVENTS_BEGIN= 51, // New Maria event numbers start from here ANNOTATE_ROWS_EVENT= 51, ENUM_END_EVENT }; together with the corresponding extension of 'post_header_len' array in the Format description event. (This extension does not affect the compatibility of the binary log). Here is how Format description event looks like with this extension: ************************ FORMAT_DESCRIPTION_EVENT ************************ 00000004 | A1 A0 2C 4B | time_when = 1261215905 00000008 | 0F | event_type = 15 00000009 | 64 00 00 00 | server_id = 100 0000000D | 7F 00 00 00 | event_len = 127 00000011 | 83 00 00 00 | log_pos = 00000083 00000015 | 01 00 | flags = LOG_EVENT_BINLOG_IN_USE_F ------------------------ 00000017 | 04 00 | binlog_ver = 4 00000019 | 35 2E 32 2E | server_ver = 5.2.0-MariaDB-alpha-debug-log ..... ... 0000004B | A1 A0 2C 4B | time_created = 1261215905 0000004F | 13 | common_header_len = 19 ------------------------ post_header_len ------------------------ 00000050 | 38 | 56 - START_EVENT_V3 [1] ..... ... 00000069 | 02 | 2 - INCIDENT_EVENT [26] 0000006A | 00 | 0 - RESERVED [27] ..... ... 00000081 | 00 | 0 - RESERVED [50] 00000082 | 00 | 0 - ANNOTATE_RBR_EVENT [51] ************************ 2. Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || thd->server_id == 0 /* slave == mysqlbinlog */ ) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events is applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; When the saved Annotate_rows object may be deleted? When all corresponding Rows events will be processed, i.e. before processing the first non-Rows event (note that Annotate_rows object resides in the binary log *after* the (possible) 'BEGIN' Query event which accompanies the rows events; note also that this deletion is adjusted with the case when some or all corresponding Rows events are filtered out by replicate filter rules): int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) rli->free_annotate_event(); apply_event_and_update_pos(ev, ...); if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ (type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT ) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

It's also never used if the value of + join_cache_level is equal to 0. + The other valid settings of join_cache_level lay in the interval 1..8. + If join_cache_level==1|2 then join buffer is used only for inner joins + with 'JT_ALL' access method. + If join_cache_level==3|4 then join buffer is used for any join operation + (inner join, outer join, semi-join) with 'JT_ALL' access method. + If 'JT_ALL' access method is used to read rows of the joined table then + always a JOIN_CACHE_BNL object is employed. + If an index is used to access rows of the joined table and the value of + join_cache_level==5|6 then a JOIN_CACHE_BKA object is employed. + If an index is used to access rows of the joined table and the value of + join_cache_level==7|8 then a JOIN_CACHE_BKA_UNIQUE object is employed. + If the value of join_cache_level is odd then creation of a non-linked + join cache is forced. + If the function decides that a join buffer can be used to join the table + 'tab' then it sets the value of tab->use_join_buffer to TRUE and assigns + the selected join cache object to the field 'cache' of the previous + join table. + If the function creates a join cache object it tries to initialize it. The + failure to do this results in an invocation of the function that destructs + the created object. + + NOTES + An inner table of a nested outer join or a nested semi-join can be currently + joined only when a linked cache object is employed. In these cases setting + join cache level to an odd number results in denial of usage of any join + buffer when joining the table. + For a nested outer join/semi-join, currently, we either use join buffers for + all inner tables or for none of them. + Some engines (e.g. Falcon) currently allow to use only a join cache + of the type JOIN_CACHE_BKA_UNIQUE when the joined table is accessed through + an index. For these engines setting the value of join_cache_level to 5 or 6 + results in that no join buffer is used to join the table. + + TODO + Support BKA inside SJ-Materialization nests.

Outline of Annotate_rows event behavior +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Each Annotate_rows_log_event object has two private members describing the +corresponding query: + + char *m_query_txt; + uint m_query_len; + +When the object is created for writing to a binary log, this query is taken +from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix +as well as other implementation details): + + Annotate_rows_log_event(THD *thd) + { + m_query_txt = thd->query(); + m_query_len = thd->query_length(); + } + +When the object is read from a binary log, the query is taken from the buffer +containing the binary log representation of the event (this buffer is allocated +in Log_event object from which all Log events are derived): + + Annotate_rows_log_event(char *buf, uint event_len, + Format_description_log_event *desc) + { + m_query_len = event_len - desc->common_header_len; + m_query_txt = buf + desc->common_header_len; + } + +The events are written to the binary log by the Log_event::write() member +which calls virtual write_data_header() and write_data_body() members +("data header" and "post header" are synonym in replication terminology). +In our case, data header is empty and data body is just the query: + + bool write_data_body(IO_CACHE *file) + { + return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); + } + +Printing the event is just printing the query: + + void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) + { + my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); + } + +3. How Master writes Annotate_rows events to the binary log +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The event is written to the binary log just before the group of Table_map +events which precede corresponding Rows events (one query may generate +several Table map events in the binary log, but the corresponding +Annotate_rows event must be written only once before the first Table map +event; hence the boolean variable 'with_annotate' below): + + int write_locked_table_maps(THD *thd) + { ... + bool with_annotate= thd->variables.binlog_annotate_rows_events; + ... + for (uint i= 0; i < ... <number of tables> ...; ++i) + { ... + thd->binlog_write_table_map(table, ..., with_annotate); + with_annotate= 0; // write Annotate_event not more than once + ... + } + ... + } + + int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) + { ... + Table_map_log_event the_event(...); + ... + if (with_annotate) + { + Annotate_rows_log_event anno(this); + mysql_bin_log.write(&anno); + } + + mysql_bin_log.write(&the_event); + ... + } + +4. How slave treats replicate-annotate-rows-events option +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The replicate-annotate-rows-events option is treated just as the session +value of the binlog_annotate_rows_events variable for the slave IO and +SQL threads. This setting is done during initialization of these threads: + + pthread_handler_t handle_slave_io(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_IO); + ... + } + + pthread_handler_t handle_slave_sql(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_SQL); + ... + } + + int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) + { ... + thd->variables.binlog_annotate_rows_events= + opt_replicate_annotate_rows_events; + ... + } + +5. How slave IO thread requests Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +When requesting an event, the slave should inform the master whether +it should send Annotate_rows events or not. To that end we add a new +BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: + + #define BINLOG_DUMP_NON_BLOCK 1 + #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 + + pthread_handler_t handle_slave_io(void *arg) + { ... + request_dump(mysql, ...); + ... + } + + int request_dump(MYSQL* mysql, ...) + { ... + if (opt_log_slave_updates && + mi->io_thd->variables.binlog_annotate_rows_events) + binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; + ... + int2store(buf + 4, binlog_flags); + ... + simple_command(mysql, COM_BINLOG_DUMP, buf, ...); + ... + } + +6. How master executes the request +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + case COM_BINLOG_DUMP: + { ... + flags= uint2korr(packet + 4); + ... + mysql_binlog_send(thd, ..., flags); + ... + } + + void mysql_binlog_send(THD* thd, ..., ushort flags) + { ... + Log_event::read_log_event(&log, packet, ...); + ... + if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || + flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || + thd->server_id == 0 /* slave == mysqlbinlog */ ) + { + my_net_write(net, packet->ptr(), packet->length()); + } + ... + } + +7. How slave SQL thread processes Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The slave processes each recieved event by "applying" it, i.e. by +calling the Log_event::apply_event() function which in turn calls +the virtual do_apply_event() member specific for each type of the +event. + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev = next_event(rli); + ... + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + + int apply_event_and_update_pos(Log_event *ev, ...) + { ... + ev->apply_event(...); + ... + } + + int Log_event::apply_event(...) + { + return do_apply_event(...); + } + +What does it mean to "apply" an Annotate_rows event? It means to set current +thd query to that of the described by the event, i.e. to the query which +caused the subsequent Rows events (see "How Master writes Annotate_rows +events to the binary log" to follow what happens further when the subsequent +Rows events is applied): + + int Annotate_rows_log_event::do_apply_event(...) + { + thd->set_query(m_query_txt, m_query_len); + } + +NOTE. I am not sure, but possibly current values of thd->query and +thd->query_length should be saved before calling set_query() and to be +restored on the Annotate_rows_log_event object deletion. +Is it really needed ? + +After calling this do_apply_event() function we may not delete the +Annotate_rows_log_event object immediatedly (see exec_relay_log_event() +above) because thd->query now points to the string inside this object. +We may keep the pointer to this object in the Relay_log_info: + + class Relay_log_info + { + public: + ... + void set_annotate_event(Annotate_rows_log_event*); + Annotate_rows_log_event* get_annotate_event(); + void free_annotate_event(); + ... + private: + Annotate_rows_log_event* m_annotate_event; + }; + +When the saved Annotate_rows object may be deleted? When all corresponding +Rows events will be processed, i.e. before processing the first non-Rows +event (note that Annotate_rows object resides in the binary log *after* +the (possible) 'BEGIN' Query event which accompanies the rows events; note +also that this deletion is adjusted with the case when some or all +corresponding Rows events are filtered out by replicate filter rules): + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev= next_event(rli); + ... + if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) + rli->free_annotate_event(); + + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) + rli->set_annotate_event((Annotate_rows_log_event*) ev); + else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + +where + + #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ + (type) == WRITE_ROWS_EVENT || \ + (type) == UPDATE_ROWS_EVENT || \ + (type) == DELETE_ROWS_EVENT ) + +8. General remarks +~~~~~~~~~~~~~~~~~~ +Kristian noticed that introducing new log event type should be coordinated +somehow with MySQL/Sun: + + Kristian: The numeric code for this event must be assigned carefully. + It should be coordinated with MySQL/Sun, otherwise we can get into a + situation where MySQL uses the same numeric code for one event that + MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two + impossible. + Alex: I reserved about 20 numbers not to have possible conflicts + with MySQL. + Kristian: Still, I think it would be appropriate to send a polite email + to internals(a)lists.mysql.com about this and suggesting to reserve the + event number. + +Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT +flag taking into account that MySQL/Sun may also introduce a flag with the +same value to be used in the request_dump-mysql_binlog_send interface. +But this is mainly the question of merging: if a conflict concerning this +flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value +(this does not require additional changes in the code). -=-=(Alexi - Sat, 19 Dec 2009, 15:41)=-=- High-Level Specification modified. --- /tmp/wklog.47.old.14545 2009-12-19 15:41:21.000000000 +0200 +++ /tmp/wklog.47.new.14545 2009-12-19 15:41:21.000000000 +0200 @@ -1,122 +1,107 @@ -First suggestion: - -> I think for this we would actually need a new binlog event type -> (Comment_log_event?).

(This extension does not affect the compatibility of the binary log). Here is how Format description event looks like with this extension: ************************ FORMAT_DESCRIPTION_EVENT ************************ 00000004 | A1 A0 2C 4B | time_when = 1261215905 00000008 | 0F | event_type = 15 00000009 | 64 00 00 00 | server_id = 100 0000000D | 7F 00 00 00 | event_len = 127 00000011 | 83 00 00 00 | log_pos = 00000083 00000015 | 01 00 | flags = LOG_EVENT_BINLOG_IN_USE_F ------------------------ 00000017 | 04 00 | binlog_ver = 4 00000019 | 35 2E 32 2E | server_ver = 5.2.0-MariaDB-alpha-debug-log ..... ... 0000004B | A1 A0 2C 4B | time_created = 1261215905 0000004F | 13 | common_header_len = 19 ------------------------ post_header_len ------------------------ 00000050 | 38 | 56 - START_EVENT_V3 [1] ..... ... 00000069 | 02 | 2 - INCIDENT_EVENT [26] 0000006A | 00 | 0 - RESERVED [27] ..... ... 00000081 | 00 | 0 - RESERVED [50] 00000082 | 00 | 0 - ANNOTATE_ROWS_EVENT [51] ************************ 2. Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } NOTE. mysqlbinlog, when remotely requesting BINLOG_DUMP by calling the simple_command() function, should also use this flag if it wants (in case of the --print-annotate-rows-events option set) to recieve Annotate_rows events. 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events are applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object.

General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

Outline of Annotate_rows event behavior +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Each Annotate_rows_log_event object has two private members describing the +corresponding query: + + char *m_query_txt; + uint m_query_len; + +When the object is created for writing to a binary log, this query is taken +from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix +as well as other implementation details): + + Annotate_rows_log_event(THD *thd) + { + m_query_txt = thd->query(); + m_query_len = thd->query_length(); + } + +When the object is read from a binary log, the query is taken from the buffer +containing the binary log representation of the event (this buffer is allocated +in Log_event object from which all Log events are derived): + + Annotate_rows_log_event(char *buf, uint event_len, + Format_description_log_event *desc) + { + m_query_len = event_len - desc->common_header_len; + m_query_txt = buf + desc->common_header_len; + } + +The events are written to the binary log by the Log_event::write() member +which calls virtual write_data_header() and write_data_body() members +("data header" and "post header" are synonym in replication terminology). +In our case, data header is empty and data body is just the query: + + bool write_data_body(IO_CACHE *file) + { + return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); + } + +Printing the event is just printing the query: + + void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) + { + my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); + } + +3. How Master writes Annotate_rows events to the binary log +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The event is written to the binary log just before the group of Table_map +events which precede corresponding Rows events (one query may generate +several Table map events in the binary log, but the corresponding +Annotate_rows event must be written only once before the first Table map +event; hence the boolean variable 'with_annotate' below): + + int write_locked_table_maps(THD *thd) + { ... + bool with_annotate= thd->variables.binlog_annotate_rows_events; + ... + for (uint i= 0; i < ... <number of tables> ...; ++i) + { ... + thd->binlog_write_table_map(table, ..., with_annotate); + with_annotate= 0; // write Annotate_event not more than once + ... + } + ... + } + + int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) + { ... + Table_map_log_event the_event(...); + ... + if (with_annotate) + { + Annotate_rows_log_event anno(this); + mysql_bin_log.write(&anno); + } + + mysql_bin_log.write(&the_event); + ... + } + +4. How slave treats replicate-annotate-rows-events option +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The replicate-annotate-rows-events option is treated just as the session +value of the binlog_annotate_rows_events variable for the slave IO and +SQL threads. This setting is done during initialization of these threads: + + pthread_handler_t handle_slave_io(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_IO); + ... + } + + pthread_handler_t handle_slave_sql(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_SQL); + ... + } + + int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) + { ... + thd->variables.binlog_annotate_rows_events= + opt_replicate_annotate_rows_events; + ... + } + +5. How slave IO thread requests Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +When requesting an event, the slave should inform the master whether +it should send Annotate_rows events or not. To that end we add a new +BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: + + #define BINLOG_DUMP_NON_BLOCK 1 + #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 + + pthread_handler_t handle_slave_io(void *arg) + { ... + request_dump(mysql, ...); + ... + } + + int request_dump(MYSQL* mysql, ...) + { ... + if (opt_log_slave_updates && + mi->io_thd->variables.binlog_annotate_rows_events) + binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; + ... + int2store(buf + 4, binlog_flags); + ... + simple_command(mysql, COM_BINLOG_DUMP, buf, ...); + ... + } + +6. How master executes the request +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + case COM_BINLOG_DUMP: + { ... + flags= uint2korr(packet + 4); + ... + mysql_binlog_send(thd, ..., flags); + ... + } + + void mysql_binlog_send(THD* thd, ..., ushort flags) + { ... + Log_event::read_log_event(&log, packet, ...); + ... + if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || + flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || + thd->server_id == 0 /* slave == mysqlbinlog */ ) + { + my_net_write(net, packet->ptr(), packet->length()); + } + ... + } + +7. How slave SQL thread processes Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The slave processes each recieved event by "applying" it, i.e. by +calling the Log_event::apply_event() function which in turn calls +the virtual do_apply_event() member specific for each type of the +event. + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev = next_event(rli); + ... + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + + int apply_event_and_update_pos(Log_event *ev, ...) + { ... + ev->apply_event(...); + ... + } + + int Log_event::apply_event(...) + { + return do_apply_event(...); + } + +What does it mean to "apply" an Annotate_rows event? It means to set current +thd query to that of the described by the event, i.e. to the query which +caused the subsequent Rows events (see "How Master writes Annotate_rows +events to the binary log" to follow what happens further when the subsequent +Rows events is applied): + + int Annotate_rows_log_event::do_apply_event(...) + { + thd->set_query(m_query_txt, m_query_len); + } + +NOTE. I am not sure, but possibly current values of thd->query and +thd->query_length should be saved before calling set_query() and to be +restored on the Annotate_rows_log_event object deletion. +Is it really needed ? + +After calling this do_apply_event() function we may not delete the +Annotate_rows_log_event object immediatedly (see exec_relay_log_event() +above) because thd->query now points to the string inside this object. +We may keep the pointer to this object in the Relay_log_info: + + class Relay_log_info + { + public: + ... + void set_annotate_event(Annotate_rows_log_event*); + Annotate_rows_log_event* get_annotate_event(); + void free_annotate_event(); + ... + private: + Annotate_rows_log_event* m_annotate_event; + }; + +When the saved Annotate_rows object may be deleted?

(This extension does not affect the compatibility of the binary log). Here is how Format description event looks like with this extension: ************************ FORMAT_DESCRIPTION_EVENT ************************ 00000004 | A1 A0 2C 4B | time_when = 1261215905 00000008 | 0F | event_type = 15 00000009 | 64 00 00 00 | server_id = 100 0000000D | 7F 00 00 00 | event_len = 127 00000011 | 83 00 00 00 | log_pos = 00000083 00000015 | 01 00 | flags = LOG_EVENT_BINLOG_IN_USE_F ------------------------ 00000017 | 04 00 | binlog_ver = 4 00000019 | 35 2E 32 2E | server_ver = 5.2.0-MariaDB-alpha-debug-log ..... ... 0000004B | A1 A0 2C 4B | time_created = 1261215905 0000004F | 13 | common_header_len = 19 ------------------------ post_header_len ------------------------ 00000050 | 38 | 56 - START_EVENT_V3 [1] ..... ... 00000069 | 02 | 2 - INCIDENT_EVENT [26] 0000006A | 00 | 0 - RESERVED [27] ..... ... 00000081 | 00 | 0 - RESERVED [50] 00000082 | 00 | 0 - ANNOTATE_ROWS_EVENT [51] ************************ 2. Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } NOTE. mysqlbinlog, when remotely requesting BINLOG_DUMP by calling the simple_command() function, should also use this flag if it wants (in case of the --print-annotate-rows-events option set) to recieve Annotate_rows events. 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events are applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; The saved Annotate_rows object should be deleted when all corresponding Rows events will be processed: int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... apply_event_and_update_pos(ev, ...); if (rli->get_annotate_event() && is_last_rows_event(ev)) rli->free_annotate_event(); else if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where bool is_last_rows_event(Log_event* ev) { Log_event_type type= ev->get_type_code(); if (IS_ROWS_EVENT_TYPE(type)) { Rows_log_event* rows= (Rows_log_event*)ev; return rows->get_flags(Rows_log_event::STMT_END_F); } return 0; } #define IS_ROWS_EVENT_TYPE(type) ((type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

Outline of Annotate_rows event behavior +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Each Annotate_rows_log_event object has two private members describing the +corresponding query: + + char *m_query_txt; + uint m_query_len; + +When the object is created for writing to a binary log, this query is taken +from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix +as well as other implementation details): + + Annotate_rows_log_event(THD *thd) + { + m_query_txt = thd->query(); + m_query_len = thd->query_length(); + } + +When the object is read from a binary log, the query is taken from the buffer +containing the binary log representation of the event (this buffer is allocated +in Log_event object from which all Log events are derived): + + Annotate_rows_log_event(char *buf, uint event_len, + Format_description_log_event *desc) + { + m_query_len = event_len - desc->common_header_len; + m_query_txt = buf + desc->common_header_len; + } + +The events are written to the binary log by the Log_event::write() member +which calls virtual write_data_header() and write_data_body() members +("data header" and "post header" are synonym in replication terminology). +In our case, data header is empty and data body is just the query: + + bool write_data_body(IO_CACHE *file) + { + return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); + } + +Printing the event is just printing the query: + + void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) + { + my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); + } + +3. How Master writes Annotate_rows events to the binary log +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The event is written to the binary log just before the group of Table_map +events which precede corresponding Rows events (one query may generate +several Table map events in the binary log, but the corresponding +Annotate_rows event must be written only once before the first Table map +event; hence the boolean variable 'with_annotate' below): + + int write_locked_table_maps(THD *thd) + { ... + bool with_annotate= thd->variables.binlog_annotate_rows_events; + ... + for (uint i= 0; i < ... <number of tables> ...; ++i) + { ... + thd->binlog_write_table_map(table, ..., with_annotate); + with_annotate= 0; // write Annotate_event not more than once + ... + } + ... + } + + int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) + { ... + Table_map_log_event the_event(...); + ... + if (with_annotate) + { + Annotate_rows_log_event anno(this); + mysql_bin_log.write(&anno); + } + + mysql_bin_log.write(&the_event); + ... + } + +4. How slave treats replicate-annotate-rows-events option +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The replicate-annotate-rows-events option is treated just as the session +value of the binlog_annotate_rows_events variable for the slave IO and +SQL threads. This setting is done during initialization of these threads: + + pthread_handler_t handle_slave_io(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_IO); + ... + } + + pthread_handler_t handle_slave_sql(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_SQL); + ... + } + + int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) + { ... + thd->variables.binlog_annotate_rows_events= + opt_replicate_annotate_rows_events; + ... + } + +5. How slave IO thread requests Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +When requesting an event, the slave should inform the master whether +it should send Annotate_rows events or not. To that end we add a new +BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: + + #define BINLOG_DUMP_NON_BLOCK 1 + #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 + + pthread_handler_t handle_slave_io(void *arg) + { ... + request_dump(mysql, ...); + ... + } + + int request_dump(MYSQL* mysql, ...) + { ... + if (opt_log_slave_updates && + mi->io_thd->variables.binlog_annotate_rows_events) + binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; + ... + int2store(buf + 4, binlog_flags); + ... + simple_command(mysql, COM_BINLOG_DUMP, buf, ...); + ... + } + +6. How master executes the request +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + case COM_BINLOG_DUMP: + { ... + flags= uint2korr(packet + 4); + ... + mysql_binlog_send(thd, ..., flags); + ... + } + + void mysql_binlog_send(THD* thd, ..., ushort flags) + { ... + Log_event::read_log_event(&log, packet, ...); + ... + if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || + flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || + thd->server_id == 0 /* slave == mysqlbinlog */ ) + { + my_net_write(net, packet->ptr(), packet->length()); + } + ... + } + +7. How slave SQL thread processes Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The slave processes each recieved event by "applying" it, i.e. by +calling the Log_event::apply_event() function which in turn calls +the virtual do_apply_event() member specific for each type of the +event. + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev = next_event(rli); + ... + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + + int apply_event_and_update_pos(Log_event *ev, ...) + { ... + ev->apply_event(...); + ... + } + + int Log_event::apply_event(...) + { + return do_apply_event(...); + } + +What does it mean to "apply" an Annotate_rows event? It means to set current +thd query to that of the described by the event, i.e. to the query which +caused the subsequent Rows events (see "How Master writes Annotate_rows +events to the binary log" to follow what happens further when the subsequent +Rows events is applied): + + int Annotate_rows_log_event::do_apply_event(...) + { + thd->set_query(m_query_txt, m_query_len); + } + +NOTE. I am not sure, but possibly current values of thd->query and +thd->query_length should be saved before calling set_query() and to be +restored on the Annotate_rows_log_event object deletion. +Is it really needed ? + +After calling this do_apply_event() function we may not delete the +Annotate_rows_log_event object immediatedly (see exec_relay_log_event() +above) because thd->query now points to the string inside this object. +We may keep the pointer to this object in the Relay_log_info: + + class Relay_log_info + { + public: + ... + void set_annotate_event(Annotate_rows_log_event*); + Annotate_rows_log_event* get_annotate_event(); + void free_annotate_event(); + ... + private: + Annotate_rows_log_event* m_annotate_event; + }; + +When the saved Annotate_rows object may be deleted? When all corresponding +Rows events will be processed, i.e. before processing the first non-Rows +event (note that Annotate_rows object resides in the binary log *after* +the (possible) 'BEGIN' Query event which accompanies the rows events; note +also that this deletion is adjusted with the case when some or all +corresponding Rows events are filtered out by replicate filter rules): + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev= next_event(rli); + ... + if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) + rli->free_annotate_event(); + + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) + rli->set_annotate_event((Annotate_rows_log_event*) ev); + else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + +where + + #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ + (type) == WRITE_ROWS_EVENT || \ + (type) == UPDATE_ROWS_EVENT || \ + (type) == DELETE_ROWS_EVENT ) + +8. General remarks +~~~~~~~~~~~~~~~~~~ +Kristian noticed that introducing new log event type should be coordinated +somehow with MySQL/Sun: + + Kristian: The numeric code for this event must be assigned carefully. + It should be coordinated with MySQL/Sun, otherwise we can get into a + situation where MySQL uses the same numeric code for one event that + MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two + impossible. + Alex: I reserved about 20 numbers not to have possible conflicts + with MySQL. + Kristian: Still, I think it would be appropriate to send a polite email + to internals(a)lists.mysql.com about this and suggesting to reserve the + event number. + +Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT +flag taking into account that MySQL/Sun may also introduce a flag with the +same value to be used in the request_dump-mysql_binlog_send interface. +But this is mainly the question of merging: if a conflict concerning this +flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value +(this does not require additional changes in the code). -=-=(Alexi - Sat, 19 Dec 2009, 15:41)=-=- High-Level Specification modified. --- /tmp/wklog.47.old.14545 2009-12-19 15:41:21.000000000 +0200 +++ /tmp/wklog.47.new.14545 2009-12-19 15:41:21.000000000 +0200 @@ -1,122 +1,107 @@ -First suggestion: - -> I think for this we would actually need a new binlog event type -> (Comment_log_event?).

(This extension does not affect the compatibility of the binary log). Here is how Format description event looks like with this extension: ************************ FORMAT_DESCRIPTION_EVENT ************************ 00000004 | A1 A0 2C 4B | time_when = 1261215905 00000008 | 0F | event_type = 15 00000009 | 64 00 00 00 | server_id = 100 0000000D | 7F 00 00 00 | event_len = 127 00000011 | 83 00 00 00 | log_pos = 00000083 00000015 | 01 00 | flags = LOG_EVENT_BINLOG_IN_USE_F ------------------------ 00000017 | 04 00 | binlog_ver = 4 00000019 | 35 2E 32 2E | server_ver = 5.2.0-MariaDB-alpha-debug-log ..... ... 0000004B | A1 A0 2C 4B | time_created = 1261215905 0000004F | 13 | common_header_len = 19 ------------------------ post_header_len ------------------------ 00000050 | 38 | 56 - START_EVENT_V3 [1] ..... ... 00000069 | 02 | 2 - INCIDENT_EVENT [26] 0000006A | 00 | 0 - RESERVED [27] ..... ... 00000081 | 00 | 0 - RESERVED [50] 00000082 | 00 | 0 - ANNOTATE_ROWS_EVENT [51] ************************ 2. Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } NOTE. mysqlbinlog, when remotely requesting BINLOG_DUMP by calling the simple_command() function, should also use this flag if it wants (in case of the --print-annotate-rows-events option set) to recieve Annotate_rows events. 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events are applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; The saved Annotate_rows object should be deleted when all corresponding Rows events will be processed: int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... apply_event_and_update_pos(ev, ...); if (rli->get_annotate_event() && is_last_rows_event(ev)) rli->free_annotate_event(); else if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where bool is_last_rows_event(Log_event* ev) { Log_event_type type= ev->get_type_code(); if (IS_ROWS_EVENT_TYPE(type)) { Rows_log_event* rows= (Rows_log_event*)ev; return rows->get_flags(Rows_log_event::STMT_END_F); } return 0; } #define IS_ROWS_EVENT_TYPE(type) ((type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

Outline of Annotate_rows event behavior +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Each Annotate_rows_log_event object has two private members describing the +corresponding query: + + char *m_query_txt; + uint m_query_len; + +When the object is created for writing to a binary log, this query is taken +from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix +as well as other implementation details): + + Annotate_rows_log_event(THD *thd) + { + m_query_txt = thd->query(); + m_query_len = thd->query_length(); + } + +When the object is read from a binary log, the query is taken from the buffer +containing the binary log representation of the event (this buffer is allocated +in Log_event object from which all Log events are derived): + + Annotate_rows_log_event(char *buf, uint event_len, + Format_description_log_event *desc) + { + m_query_len = event_len - desc->common_header_len; + m_query_txt = buf + desc->common_header_len; + } + +The events are written to the binary log by the Log_event::write() member +which calls virtual write_data_header() and write_data_body() members +("data header" and "post header" are synonym in replication terminology). +In our case, data header is empty and data body is just the query: + + bool write_data_body(IO_CACHE *file) + { + return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); + } + +Printing the event is just printing the query: + + void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) + { + my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); + } + +3. How Master writes Annotate_rows events to the binary log +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The event is written to the binary log just before the group of Table_map +events which precede corresponding Rows events (one query may generate +several Table map events in the binary log, but the corresponding +Annotate_rows event must be written only once before the first Table map +event; hence the boolean variable 'with_annotate' below): + + int write_locked_table_maps(THD *thd) + { ... + bool with_annotate= thd->variables.binlog_annotate_rows_events; + ... + for (uint i= 0; i < ... <number of tables> ...; ++i) + { ... + thd->binlog_write_table_map(table, ..., with_annotate); + with_annotate= 0; // write Annotate_event not more than once + ... + } + ... + } + + int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) + { ... + Table_map_log_event the_event(...); + ... + if (with_annotate) + { + Annotate_rows_log_event anno(this); + mysql_bin_log.write(&anno); + } + + mysql_bin_log.write(&the_event); + ... + } + +4. How slave treats replicate-annotate-rows-events option +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The replicate-annotate-rows-events option is treated just as the session +value of the binlog_annotate_rows_events variable for the slave IO and +SQL threads. This setting is done during initialization of these threads: + + pthread_handler_t handle_slave_io(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_IO); + ... + } + + pthread_handler_t handle_slave_sql(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_SQL); + ... + } + + int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) + { ... + thd->variables.binlog_annotate_rows_events= + opt_replicate_annotate_rows_events; + ... + } + +5. How slave IO thread requests Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +When requesting an event, the slave should inform the master whether +it should send Annotate_rows events or not. To that end we add a new +BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: + + #define BINLOG_DUMP_NON_BLOCK 1 + #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 + + pthread_handler_t handle_slave_io(void *arg) + { ... + request_dump(mysql, ...); + ... + } + + int request_dump(MYSQL* mysql, ...) + { ... + if (opt_log_slave_updates && + mi->io_thd->variables.binlog_annotate_rows_events) + binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; + ... + int2store(buf + 4, binlog_flags); + ... + simple_command(mysql, COM_BINLOG_DUMP, buf, ...); + ... + } + +6. How master executes the request +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + case COM_BINLOG_DUMP: + { ... + flags= uint2korr(packet + 4); + ... + mysql_binlog_send(thd, ..., flags); + ... + } + + void mysql_binlog_send(THD* thd, ..., ushort flags) + { ... + Log_event::read_log_event(&log, packet, ...); + ... + if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || + flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || + thd->server_id == 0 /* slave == mysqlbinlog */ ) + { + my_net_write(net, packet->ptr(), packet->length()); + } + ... + } + +7. How slave SQL thread processes Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The slave processes each recieved event by "applying" it, i.e. by +calling the Log_event::apply_event() function which in turn calls +the virtual do_apply_event() member specific for each type of the +event. + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev = next_event(rli); + ... + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + + int apply_event_and_update_pos(Log_event *ev, ...) + { ... + ev->apply_event(...); + ... + } + + int Log_event::apply_event(...) + { + return do_apply_event(...); + } + +What does it mean to "apply" an Annotate_rows event? It means to set current +thd query to that of the described by the event, i.e. to the query which +caused the subsequent Rows events (see "How Master writes Annotate_rows +events to the binary log" to follow what happens further when the subsequent +Rows events is applied): + + int Annotate_rows_log_event::do_apply_event(...) + { + thd->set_query(m_query_txt, m_query_len); + } + +NOTE. I am not sure, but possibly current values of thd->query and +thd->query_length should be saved before calling set_query() and to be +restored on the Annotate_rows_log_event object deletion. +Is it really needed ? + +After calling this do_apply_event() function we may not delete the +Annotate_rows_log_event object immediatedly (see exec_relay_log_event() +above) because thd->query now points to the string inside this object. +We may keep the pointer to this object in the Relay_log_info: + + class Relay_log_info + { + public: + ... + void set_annotate_event(Annotate_rows_log_event*); + Annotate_rows_log_event* get_annotate_event(); + void free_annotate_event(); + ... + private: + Annotate_rows_log_event* m_annotate_event; + }; + +When the saved Annotate_rows object may be deleted? When all corresponding +Rows events will be processed, i.e. before processing the first non-Rows +event (note that Annotate_rows object resides in the binary log *after* +the (possible) 'BEGIN' Query event which accompanies the rows events; note +also that this deletion is adjusted with the case when some or all +corresponding Rows events are filtered out by replicate filter rules): + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev= next_event(rli); + ... + if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) + rli->free_annotate_event(); + + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) + rli->set_annotate_event((Annotate_rows_log_event*) ev); + else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + +where + + #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ + (type) == WRITE_ROWS_EVENT || \ + (type) == UPDATE_ROWS_EVENT || \ + (type) == DELETE_ROWS_EVENT ) + +8. General remarks +~~~~~~~~~~~~~~~~~~ +Kristian noticed that introducing new log event type should be coordinated +somehow with MySQL/Sun: + + Kristian: The numeric code for this event must be assigned carefully. + It should be coordinated with MySQL/Sun, otherwise we can get into a + situation where MySQL uses the same numeric code for one event that + MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two + impossible. + Alex: I reserved about 20 numbers not to have possible conflicts + with MySQL. + Kristian: Still, I think it would be appropriate to send a polite email + to internals(a)lists.mysql.com about this and suggesting to reserve the + event number. + +Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT +flag taking into account that MySQL/Sun may also introduce a flag with the +same value to be used in the request_dump-mysql_binlog_send interface. +But this is mainly the question of merging: if a conflict concerning this +flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value +(this does not require additional changes in the code). -=-=(Alexi - Sat, 19 Dec 2009, 15:41)=-=- High-Level Specification modified. --- /tmp/wklog.47.old.14545 2009-12-19 15:41:21.000000000 +0200 +++ /tmp/wklog.47.new.14545 2009-12-19 15:41:21.000000000 +0200 @@ -1,122 +1,107 @@ -First suggestion: - -> I think for this we would actually need a new binlog event type -> (Comment_log_event?).

The cost of this can be that the binlog will be approximately 2x in size (especially insert of big blob's would be a bit painful), so this should be an optional feature.

(See example in the "mysqlbinlog output" section below.) 2. Server option: --binlog-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Tells the master to write Annotate_rows events to the binary log. * Variable Name: binlog_annotate_rows_events * Scope: Global & Session * Access Type: Dynamic * Data Type: bool * Default Value: OFF NOTE. Session values allows to annotate only some selected statements: ... SET SESSION binlog_annotate_rows_events=ON; ... statements to be annotated ... SET SESSION binlog_annotate_rows_events=OFF; ... statements not to be annotated ... 3. Server option: --replicate-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Tells the slave to reproduce Annotate_rows events recieved from the master in its own binary log (sensible only in pair with log-slave-updates option). * Variable Name: replicate_annotate_rows_events * Scope: Global * Access Type: Read only * Data Type: bool * Default Value: OFF NOTE. Why do we additionally need this 'replicate' option? Why not to make the slave to reproduce this events when its binlog-annotate-rows-events global value is ON? Well, because, for example, we may want to configure the slave which should reproduce Annotate_rows events but has global binlog-annotate-rows-events = OFF meaning this to be the default value for the client threads (see also "How slave treats replicate-annotate-rows-events option" in LLD part). 4. mysqlbinlog option: --print-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ With this option, mysqlbinlog prints the content of Annotate_rows events (if the binary log does contain them). Without this option (i.e. by default), mysqlbinlog skips Annotate_rows events. 5. mysqlbinlog output ~~~~~~~~~~~~~~~~~~~~~ With --print-annotate-rows-events, mysqlbinlog outputs Annotate_rows events in a form like this: ... # at 1646 #091219 12:45:26 server id 100 end_log_pos 1714 Query thread_id=1 exec_time=0 error_code=0 SET TIMESTAMP=1261215926/*!*/; BEGIN /*!*/; # at 1714 # at 1812 # at 1853 # at 1894 # at 1938 #091219 12:45:26 server id 100 end_log_pos 1812 Query: `DELETE t1, t2 FROM t1 INNER JOIN t2 INNER JOIN t3 WHERE t1.a=t2.a AND t2.a=t3.a` #091219 12:45:26 server id 100 end_log_pos 1853 Table_map: `test`.`t1` mapped to number 16 #091219 12:45:26 server id 100 end_log_pos 1894 Table_map: `test`.`t2` mapped to number 17 #091219 12:45:26 server id 100 end_log_pos 1938 Delete_rows: table id 16 #091219 12:45:26 server id 100 end_log_pos 1982 Delete_rows: table id 17 flags: STMT_END_F ...

(This extension does not affect the compatibility of the binary log). Here is how Format description event looks like with this extension: ************************ FORMAT_DESCRIPTION_EVENT ************************ 00000004 | A1 A0 2C 4B | time_when = 1261215905 00000008 | 0F | event_type = 15 00000009 | 64 00 00 00 | server_id = 100 0000000D | 7F 00 00 00 | event_len = 127 00000011 | 83 00 00 00 | log_pos = 00000083 00000015 | 01 00 | flags = LOG_EVENT_BINLOG_IN_USE_F ------------------------ 00000017 | 04 00 | binlog_ver = 4 00000019 | 35 2E 32 2E | server_ver = 5.2.0-MariaDB-alpha-debug-log ..... ... 0000004B | A1 A0 2C 4B | time_created = 1261215905 0000004F | 13 | common_header_len = 19 ------------------------ post_header_len ------------------------ 00000050 | 38 | 56 - START_EVENT_V3 [1] ..... ... 00000069 | 02 | 2 - INCIDENT_EVENT [26] 0000006A | 00 | 0 - RESERVED [27] ..... ... 00000081 | 00 | 0 - RESERVED [50] 00000082 | 00 | 0 - ANNOTATE_ROWS_EVENT [51] ************************ 2. Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || thd->server_id == 0 /* slave == mysqlbinlog */ ) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events are applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; The saved Annotate_rows object should be deleted when all corresponding Rows events will be processed: int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... apply_event_and_update_pos(ev, ...); if (rli->get_annotate_event() && is_last_rows_event(ev)) rli->free_annotate_event(); else if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where bool is_last_rows_event(Log_event* ev) { Log_event_type type= ev->get_type_code(); if (IS_ROWS_EVENT_TYPE(type)) { Rows_log_event* rows= (Rows_log_event*)ev; return rows->get_flags(Rows_log_event::STMT_END_F); } return 0; } #define IS_ROWS_EVENT_TYPE(type) ((type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

Outline of Annotate_rows event behavior +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Each Annotate_rows_log_event object has two private members describing the +corresponding query: + + char *m_query_txt; + uint m_query_len; + +When the object is created for writing to a binary log, this query is taken +from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix +as well as other implementation details): + + Annotate_rows_log_event(THD *thd) + { + m_query_txt = thd->query(); + m_query_len = thd->query_length(); + } + +When the object is read from a binary log, the query is taken from the buffer +containing the binary log representation of the event (this buffer is allocated +in Log_event object from which all Log events are derived): + + Annotate_rows_log_event(char *buf, uint event_len, + Format_description_log_event *desc) + { + m_query_len = event_len - desc->common_header_len; + m_query_txt = buf + desc->common_header_len; + } + +The events are written to the binary log by the Log_event::write() member +which calls virtual write_data_header() and write_data_body() members +("data header" and "post header" are synonym in replication terminology). +In our case, data header is empty and data body is just the query: + + bool write_data_body(IO_CACHE *file) + { + return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); + } + +Printing the event is just printing the query: + + void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) + { + my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); + } + +3. How Master writes Annotate_rows events to the binary log +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The event is written to the binary log just before the group of Table_map +events which precede corresponding Rows events (one query may generate +several Table map events in the binary log, but the corresponding +Annotate_rows event must be written only once before the first Table map +event; hence the boolean variable 'with_annotate' below): + + int write_locked_table_maps(THD *thd) + { ... + bool with_annotate= thd->variables.binlog_annotate_rows_events; + ... + for (uint i= 0; i < ... <number of tables> ...; ++i) + { ... + thd->binlog_write_table_map(table, ..., with_annotate); + with_annotate= 0; // write Annotate_event not more than once + ... + } + ... + } + + int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) + { ... + Table_map_log_event the_event(...); + ... + if (with_annotate) + { + Annotate_rows_log_event anno(this); + mysql_bin_log.write(&anno); + } + + mysql_bin_log.write(&the_event); + ... + } + +4. How slave treats replicate-annotate-rows-events option +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The replicate-annotate-rows-events option is treated just as the session +value of the binlog_annotate_rows_events variable for the slave IO and +SQL threads. This setting is done during initialization of these threads: + + pthread_handler_t handle_slave_io(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_IO); + ... + } + + pthread_handler_t handle_slave_sql(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_SQL); + ... + } + + int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) + { ... + thd->variables.binlog_annotate_rows_events= + opt_replicate_annotate_rows_events; + ... + } + +5. How slave IO thread requests Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +When requesting an event, the slave should inform the master whether +it should send Annotate_rows events or not. To that end we add a new +BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: + + #define BINLOG_DUMP_NON_BLOCK 1 + #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 + + pthread_handler_t handle_slave_io(void *arg) + { ... + request_dump(mysql, ...); + ... + } + + int request_dump(MYSQL* mysql, ...) + { ... + if (opt_log_slave_updates && + mi->io_thd->variables.binlog_annotate_rows_events) + binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; + ... + int2store(buf + 4, binlog_flags); + ... + simple_command(mysql, COM_BINLOG_DUMP, buf, ...); + ... + } + +6. How master executes the request +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + case COM_BINLOG_DUMP: + { ... + flags= uint2korr(packet + 4); + ... + mysql_binlog_send(thd, ..., flags); + ... + } + + void mysql_binlog_send(THD* thd, ..., ushort flags) + { ... + Log_event::read_log_event(&log, packet, ...); + ... + if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || + flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || + thd->server_id == 0 /* slave == mysqlbinlog */ ) + { + my_net_write(net, packet->ptr(), packet->length()); + } + ... + } + +7. How slave SQL thread processes Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The slave processes each recieved event by "applying" it, i.e. by +calling the Log_event::apply_event() function which in turn calls +the virtual do_apply_event() member specific for each type of the +event. + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev = next_event(rli); + ... + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + + int apply_event_and_update_pos(Log_event *ev, ...) + { ... + ev->apply_event(...); + ... + } + + int Log_event::apply_event(...) + { + return do_apply_event(...); + } + +What does it mean to "apply" an Annotate_rows event? It means to set current +thd query to that of the described by the event, i.e. to the query which +caused the subsequent Rows events (see "How Master writes Annotate_rows +events to the binary log" to follow what happens further when the subsequent +Rows events is applied): + + int Annotate_rows_log_event::do_apply_event(...) + { + thd->set_query(m_query_txt, m_query_len); + } + +NOTE. I am not sure, but possibly current values of thd->query and +thd->query_length should be saved before calling set_query() and to be +restored on the Annotate_rows_log_event object deletion. +Is it really needed ? + +After calling this do_apply_event() function we may not delete the +Annotate_rows_log_event object immediatedly (see exec_relay_log_event() +above) because thd->query now points to the string inside this object. +We may keep the pointer to this object in the Relay_log_info: + + class Relay_log_info + { + public: + ... + void set_annotate_event(Annotate_rows_log_event*); + Annotate_rows_log_event* get_annotate_event(); + void free_annotate_event(); + ... + private: + Annotate_rows_log_event* m_annotate_event; + }; + +When the saved Annotate_rows object may be deleted? When all corresponding +Rows events will be processed, i.e. before processing the first non-Rows +event (note that Annotate_rows object resides in the binary log *after* +the (possible) 'BEGIN' Query event which accompanies the rows events; note +also that this deletion is adjusted with the case when some or all +corresponding Rows events are filtered out by replicate filter rules): + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev= next_event(rli); + ... + if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) + rli->free_annotate_event(); + + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) + rli->set_annotate_event((Annotate_rows_log_event*) ev); + else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + +where + + #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ + (type) == WRITE_ROWS_EVENT || \ + (type) == UPDATE_ROWS_EVENT || \ + (type) == DELETE_ROWS_EVENT ) + +8. General remarks +~~~~~~~~~~~~~~~~~~ +Kristian noticed that introducing new log event type should be coordinated +somehow with MySQL/Sun: + + Kristian: The numeric code for this event must be assigned carefully. + It should be coordinated with MySQL/Sun, otherwise we can get into a + situation where MySQL uses the same numeric code for one event that + MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two + impossible. + Alex: I reserved about 20 numbers not to have possible conflicts + with MySQL. + Kristian: Still, I think it would be appropriate to send a polite email + to internals(a)lists.mysql.com about this and suggesting to reserve the + event number. + +Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT +flag taking into account that MySQL/Sun may also introduce a flag with the +same value to be used in the request_dump-mysql_binlog_send interface. +But this is mainly the question of merging: if a conflict concerning this +flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value +(this does not require additional changes in the code). -=-=(Alexi - Sat, 19 Dec 2009, 15:41)=-=- High-Level Specification modified. --- /tmp/wklog.47.old.14545 2009-12-19 15:41:21.000000000 +0200 +++ /tmp/wklog.47.new.14545 2009-12-19 15:41:21.000000000 +0200 @@ -1,122 +1,107 @@ -First suggestion: - -> I think for this we would actually need a new binlog event type -> (Comment_log_event?).

Server option: --binlog-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Tells the master to write Annotate_rows events to the binary log. * Variable Name: binlog_annotate_rows_events * Scope: Global & Session * Access Type: Dynamic * Data Type: bool * Default Value: OFF NOTE. Session values allows to annotate only some selected statements: ... SET SESSION binlog_annotate_rows_events=ON; ... statements to be annotated ... SET SESSION binlog_annotate_rows_events=OFF; ... statements not to be annotated ... 3. Server option: --replicate-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Tells the slave to reproduce Annotate_rows events recieved from the master in its own binary log (sensible only in pair with log-slave-updates option). * Variable Name: replicate_annotate_rows_events * Scope: Global * Access Type: Read only * Data Type: bool * Default Value: OFF NOTE. Why do we additionally need this 'replicate' option? Why not to make the slave to reproduce this events when its binlog-annotate-rows-events global value is ON? Well, because, for example, we may want to configure the slave which should reproduce Annotate_rows events but has global binlog-annotate-rows-events = OFF meaning this to be the default value for the client threads (see also "How slave treats replicate-annotate-rows-events option" in LLD part). 4. mysqlbinlog option: --print-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ With this option, mysqlbinlog prints the content of Annotate_rows events (if the binary log does contain them). Without this option (i.e. by default), mysqlbinlog skips Annotate_rows events. 5. mysqlbinlog output ~~~~~~~~~~~~~~~~~~~~~ With --print-annotate-rows-events, mysqlbinlog outputs Annotate_rows events in a form like this: ... # at 1646 #091219 12:45:26 server id 100 end_log_pos 1714 Query thread_id=1 exec_time=0 error_code=0 SET TIMESTAMP=1261215926/*!*/; BEGIN /*!*/; # at 1714 # at 1812 # at 1853 # at 1894 # at 1938 #091219 12:45:26 server id 100 end_log_pos 1812 Query: `DELETE t1, t2 FROM t1 INNER JOIN t2 INNER JOIN t3 WHERE t1.a=t2.a AND t2.a=t3.a` #091219 12:45:26 server id 100 end_log_pos 1853 Table_map: `test`.`t1` mapped to number 16 #091219 12:45:26 server id 100 end_log_pos 1894 Table_map: `test`.`t2` mapped to number 17 #091219 12:45:26 server id 100 end_log_pos 1938 Delete_rows: table id 16 #091219 12:45:26 server id 100 end_log_pos 1982 Delete_rows: table id 17 flags: STMT_END_F ...

Annotate_rows event number ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To avoid possible event numbers conflict with MySQL/Sun, we leave a gap between the last MySQL event number and the Annotate_rows event number: enum Log_event_type { ... INCIDENT_EVENT= 26, // New MySQL event numbers are to be added here MYSQL_EVENTS_END, MARIA_EVENTS_BEGIN= 51, // New Maria event numbers start from here ANNOTATE_ROWS_EVENT= 51, ENUM_END_EVENT }; together with the corresponding extension of 'post_header_len' array in the Format description event. (This extension does not affect the compatibility of the binary log). Here is how Format description event looks like with this extension: ************************ FORMAT_DESCRIPTION_EVENT ************************ 00000004 | A1 A0 2C 4B | time_when = 1261215905 00000008 | 0F | event_type = 15 00000009 | 64 00 00 00 | server_id = 100 0000000D | 7F 00 00 00 | event_len = 127 00000011 | 83 00 00 00 | log_pos = 00000083 00000015 | 01 00 | flags = LOG_EVENT_BINLOG_IN_USE_F ------------------------ 00000017 | 04 00 | binlog_ver = 4 00000019 | 35 2E 32 2E | server_ver = 5.2.0-MariaDB-alpha-debug-log ..... ... 0000004B | A1 A0 2C 4B | time_created = 1261215905 0000004F | 13 | common_header_len = 19 ------------------------ post_header_len ------------------------ 00000050 | 38 | 56 - START_EVENT_V3 [1] ..... ... 00000069 | 02 | 2 - INCIDENT_EVENT [26] 0000006A | 00 | 0 - RESERVED [27] ..... ... 00000081 | 00 | 0 - RESERVED [50] 00000082 | 00 | 0 - ANNOTATE_ROWS_EVENT [51] ************************ 2. Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || thd->server_id == 0 /* slave == mysqlbinlog */ ) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events are applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; The saved Annotate_rows object should be deleted when all corresponding Rows events will be processed: int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... apply_event_and_update_pos(ev, ...); if (rli->get_annotate_event() && is_last_rows_event(ev)) rli->free_annotate_event(); else if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where bool is_last_rows_event(Log_event* ev) { Log_event_type type= ev->get_type_code(); if (IS_ROWS_EVENT_TYPE(type)) { Rows_log_event* rows= (Rows_log_event*)ev; return rows->get_flags(Rows_log_event::STMT_END_F); } return 0; } #define IS_ROWS_EVENT_TYPE(type) ((type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

To that end we add a new +BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: + + #define BINLOG_DUMP_NON_BLOCK 1 + #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 + + pthread_handler_t handle_slave_io(void *arg) + { ... + request_dump(mysql, ...); + ... + } + + int request_dump(MYSQL* mysql, ...) + { ... + if (opt_log_slave_updates && + mi->io_thd->variables.binlog_annotate_rows_events) + binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; + ... + int2store(buf + 4, binlog_flags); + ... + simple_command(mysql, COM_BINLOG_DUMP, buf, ...); + ... + } + +6. How master executes the request +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + case COM_BINLOG_DUMP: + { ... + flags= uint2korr(packet + 4); + ... + mysql_binlog_send(thd, ..., flags); + ... + } + + void mysql_binlog_send(THD* thd, ..., ushort flags) + { ... + Log_event::read_log_event(&log, packet, ...); + ... + if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || + flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || + thd->server_id == 0 /* slave == mysqlbinlog */ ) + { + my_net_write(net, packet->ptr(), packet->length()); + } + ... + } + +7. How slave SQL thread processes Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The slave processes each recieved event by "applying" it, i.e. by +calling the Log_event::apply_event() function which in turn calls +the virtual do_apply_event() member specific for each type of the +event. + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev = next_event(rli); + ... + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + + int apply_event_and_update_pos(Log_event *ev, ...) + { ... + ev->apply_event(...); + ... + } + + int Log_event::apply_event(...) + { + return do_apply_event(...); + } + +What does it mean to "apply" an Annotate_rows event? It means to set current +thd query to that of the described by the event, i.e. to the query which +caused the subsequent Rows events (see "How Master writes Annotate_rows +events to the binary log" to follow what happens further when the subsequent +Rows events is applied): + + int Annotate_rows_log_event::do_apply_event(...) + { + thd->set_query(m_query_txt, m_query_len); + } + +NOTE. I am not sure, but possibly current values of thd->query and +thd->query_length should be saved before calling set_query() and to be +restored on the Annotate_rows_log_event object deletion. +Is it really needed ? + +After calling this do_apply_event() function we may not delete the +Annotate_rows_log_event object immediatedly (see exec_relay_log_event() +above) because thd->query now points to the string inside this object. +We may keep the pointer to this object in the Relay_log_info: + + class Relay_log_info + { + public: + ... + void set_annotate_event(Annotate_rows_log_event*); + Annotate_rows_log_event* get_annotate_event(); + void free_annotate_event(); + ... + private: + Annotate_rows_log_event* m_annotate_event; + }; + +When the saved Annotate_rows object may be deleted? When all corresponding +Rows events will be processed, i.e. before processing the first non-Rows +event (note that Annotate_rows object resides in the binary log *after* +the (possible) 'BEGIN' Query event which accompanies the rows events; note +also that this deletion is adjusted with the case when some or all +corresponding Rows events are filtered out by replicate filter rules): + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev= next_event(rli); + ... + if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) + rli->free_annotate_event(); + + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) + rli->set_annotate_event((Annotate_rows_log_event*) ev); + else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + +where + + #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ + (type) == WRITE_ROWS_EVENT || \ + (type) == UPDATE_ROWS_EVENT || \ + (type) == DELETE_ROWS_EVENT ) + +8.

(This extension does not affect the compatibility of the binary log).

Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || thd->server_id == 0 /* slave == mysqlbinlog */ ) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events are applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; The saved Annotate_rows object should be deleted when all corresponding Rows events will be processed: int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... apply_event_and_update_pos(ev, ...); if (rli->get_annotate_event() && is_last_rows_event(ev)) rli->free_annotate_event(); else if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where bool is_last_rows_event(Log_event* ev) { Log_event_type type= ev->get_type_code(); if (IS_ROWS_EVENT_TYPE(type)) { Rows_log_event* rows= (Rows_log_event*)ev; return rows->get_flags(Rows_log_event::STMT_END_F); } return 0; } #define IS_ROWS_EVENT_TYPE(type) ((type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || thd->server_id == 0 /* slave == mysqlbinlog */ ) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events are applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; When the saved Annotate_rows object may be deleted? When all corresponding Rows events will be processed, i.e. before processing the first non-Rows event (note that Annotate_rows object resides in the binary log *after* the (possible) 'BEGIN' Query event which accompanies the rows events; note also that this deletion is adjusted with the case when some or all corresponding Rows events are filtered out by replicate filter rules): int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) rli->free_annotate_event(); apply_event_and_update_pos(ev, ...); if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ (type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT ) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

Outline of Annotate_rows event behavior +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Each Annotate_rows_log_event object has two private members describing the +corresponding query: + + char *m_query_txt; + uint m_query_len; + +When the object is created for writing to a binary log, this query is taken +from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix +as well as other implementation details): + + Annotate_rows_log_event(THD *thd) + { + m_query_txt = thd->query(); + m_query_len = thd->query_length(); + } + +When the object is read from a binary log, the query is taken from the buffer +containing the binary log representation of the event (this buffer is allocated +in Log_event object from which all Log events are derived): + + Annotate_rows_log_event(char *buf, uint event_len, + Format_description_log_event *desc) + { + m_query_len = event_len - desc->common_header_len; + m_query_txt = buf + desc->common_header_len; + } + +The events are written to the binary log by the Log_event::write() member +which calls virtual write_data_header() and write_data_body() members +("data header" and "post header" are synonym in replication terminology). +In our case, data header is empty and data body is just the query: + + bool write_data_body(IO_CACHE *file) + { + return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); + } + +Printing the event is just printing the query: + + void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) + { + my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); + } + +3. How Master writes Annotate_rows events to the binary log +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The event is written to the binary log just before the group of Table_map +events which precede corresponding Rows events (one query may generate +several Table map events in the binary log, but the corresponding +Annotate_rows event must be written only once before the first Table map +event; hence the boolean variable 'with_annotate' below): + + int write_locked_table_maps(THD *thd) + { ... + bool with_annotate= thd->variables.binlog_annotate_rows_events; + ... + for (uint i= 0; i < ... <number of tables> ...; ++i) + { ... + thd->binlog_write_table_map(table, ..., with_annotate); + with_annotate= 0; // write Annotate_event not more than once + ... + } + ... + } + + int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) + { ... + Table_map_log_event the_event(...); + ... + if (with_annotate) + { + Annotate_rows_log_event anno(this); + mysql_bin_log.write(&anno); + } + + mysql_bin_log.write(&the_event); + ... + } + +4. How slave treats replicate-annotate-rows-events option +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The replicate-annotate-rows-events option is treated just as the session +value of the binlog_annotate_rows_events variable for the slave IO and +SQL threads. This setting is done during initialization of these threads: + + pthread_handler_t handle_slave_io(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_IO); + ... + } + + pthread_handler_t handle_slave_sql(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_SQL); + ... + } + + int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) + { ... + thd->variables.binlog_annotate_rows_events= + opt_replicate_annotate_rows_events; + ... + } + +5. How slave IO thread requests Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +When requesting an event, the slave should inform the master whether +it should send Annotate_rows events or not. To that end we add a new +BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: + + #define BINLOG_DUMP_NON_BLOCK 1 + #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 + + pthread_handler_t handle_slave_io(void *arg) + { ... + request_dump(mysql, ...); + ... + } + + int request_dump(MYSQL* mysql, ...) + { ... + if (opt_log_slave_updates && + mi->io_thd->variables.binlog_annotate_rows_events) + binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; + ... + int2store(buf + 4, binlog_flags); + ... + simple_command(mysql, COM_BINLOG_DUMP, buf, ...); + ... + } + +6. How master executes the request +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + case COM_BINLOG_DUMP: + { ... + flags= uint2korr(packet + 4); + ... + mysql_binlog_send(thd, ..., flags); + ... + } + + void mysql_binlog_send(THD* thd, ..., ushort flags) + { ... + Log_event::read_log_event(&log, packet, ...); + ... + if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || + flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || + thd->server_id == 0 /* slave == mysqlbinlog */ ) + { + my_net_write(net, packet->ptr(), packet->length()); + } + ... + } + +7. How slave SQL thread processes Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The slave processes each recieved event by "applying" it, i.e. by +calling the Log_event::apply_event() function which in turn calls +the virtual do_apply_event() member specific for each type of the +event. + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev = next_event(rli); + ... + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + + int apply_event_and_update_pos(Log_event *ev, ...) + { ... + ev->apply_event(...); + ... + } + + int Log_event::apply_event(...) + { + return do_apply_event(...); + } + +What does it mean to "apply" an Annotate_rows event? It means to set current +thd query to that of the described by the event, i.e. to the query which +caused the subsequent Rows events (see "How Master writes Annotate_rows +events to the binary log" to follow what happens further when the subsequent +Rows events is applied): + + int Annotate_rows_log_event::do_apply_event(...) + { + thd->set_query(m_query_txt, m_query_len); + } + +NOTE. I am not sure, but possibly current values of thd->query and +thd->query_length should be saved before calling set_query() and to be +restored on the Annotate_rows_log_event object deletion. +Is it really needed ? + +After calling this do_apply_event() function we may not delete the +Annotate_rows_log_event object immediatedly (see exec_relay_log_event() +above) because thd->query now points to the string inside this object. +We may keep the pointer to this object in the Relay_log_info: + + class Relay_log_info + { + public: + ... + void set_annotate_event(Annotate_rows_log_event*); + Annotate_rows_log_event* get_annotate_event(); + void free_annotate_event(); + ... + private: + Annotate_rows_log_event* m_annotate_event; + }; + +When the saved Annotate_rows object may be deleted?

(This extension does not affect the compatibility of the binary log). Here is how Format description event looks like with this extension: ************************ FORMAT_DESCRIPTION_EVENT ************************ 00000004 | A1 A0 2C 4B | time_when = 1261215905 00000008 | 0F | event_type = 15 00000009 | 64 00 00 00 | server_id = 100 0000000D | 7F 00 00 00 | event_len = 127 00000011 | 83 00 00 00 | log_pos = 00000083 00000015 | 01 00 | flags = LOG_EVENT_BINLOG_IN_USE_F ------------------------ 00000017 | 04 00 | binlog_ver = 4 00000019 | 35 2E 32 2E | server_ver = 5.2.0-MariaDB-alpha-debug-log ..... ... 0000004B | A1 A0 2C 4B | time_created = 1261215905 0000004F | 13 | common_header_len = 19 ------------------------ post_header_len ------------------------ 00000050 | 38 | 56 - START_EVENT_V3 [1] ..... ... 00000069 | 02 | 2 - INCIDENT_EVENT [26] 0000006A | 00 | 0 - RESERVED [27] ..... ... 00000081 | 00 | 0 - RESERVED [50] 00000082 | 00 | 0 - ANNOTATE_ROWS_EVENT [51] ************************ 2. Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || thd->server_id == 0 /* slave == mysqlbinlog */ ) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events are applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; When the saved Annotate_rows object may be deleted? When all corresponding Rows events will be processed, i.e. before processing the first non-Rows event (note that Annotate_rows object resides in the binary log *after* the (possible) 'BEGIN' Query event which accompanies the rows events; note also that this deletion is adjusted with the case when some or all corresponding Rows events are filtered out by replicate filter rules): int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) rli->free_annotate_event(); apply_event_and_update_pos(ev, ...); if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ (type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT ) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

Outline of Annotate_rows event behavior +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Each Annotate_rows_log_event object has two private members describing the +corresponding query: + + char *m_query_txt; + uint m_query_len; + +When the object is created for writing to a binary log, this query is taken +from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix +as well as other implementation details): + + Annotate_rows_log_event(THD *thd) + { + m_query_txt = thd->query(); + m_query_len = thd->query_length(); + } + +When the object is read from a binary log, the query is taken from the buffer +containing the binary log representation of the event (this buffer is allocated +in Log_event object from which all Log events are derived): + + Annotate_rows_log_event(char *buf, uint event_len, + Format_description_log_event *desc) + { + m_query_len = event_len - desc->common_header_len; + m_query_txt = buf + desc->common_header_len; + } + +The events are written to the binary log by the Log_event::write() member +which calls virtual write_data_header() and write_data_body() members +("data header" and "post header" are synonym in replication terminology). +In our case, data header is empty and data body is just the query: + + bool write_data_body(IO_CACHE *file) + { + return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); + } + +Printing the event is just printing the query: + + void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) + { + my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); + } + +3. How Master writes Annotate_rows events to the binary log +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The event is written to the binary log just before the group of Table_map +events which precede corresponding Rows events (one query may generate +several Table map events in the binary log, but the corresponding +Annotate_rows event must be written only once before the first Table map +event; hence the boolean variable 'with_annotate' below): + + int write_locked_table_maps(THD *thd) + { ... + bool with_annotate= thd->variables.binlog_annotate_rows_events; + ... + for (uint i= 0; i < ... <number of tables> ...; ++i) + { ... + thd->binlog_write_table_map(table, ..., with_annotate); + with_annotate= 0; // write Annotate_event not more than once + ... + } + ... + } + + int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) + { ... + Table_map_log_event the_event(...); + ... + if (with_annotate) + { + Annotate_rows_log_event anno(this); + mysql_bin_log.write(&anno); + } + + mysql_bin_log.write(&the_event); + ... + } + +4. How slave treats replicate-annotate-rows-events option +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The replicate-annotate-rows-events option is treated just as the session +value of the binlog_annotate_rows_events variable for the slave IO and +SQL threads. This setting is done during initialization of these threads: + + pthread_handler_t handle_slave_io(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_IO); + ... + } + + pthread_handler_t handle_slave_sql(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_SQL); + ... + } + + int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) + { ... + thd->variables.binlog_annotate_rows_events= + opt_replicate_annotate_rows_events; + ... + } + +5. How slave IO thread requests Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +When requesting an event, the slave should inform the master whether +it should send Annotate_rows events or not. To that end we add a new +BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: + + #define BINLOG_DUMP_NON_BLOCK 1 + #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 + + pthread_handler_t handle_slave_io(void *arg) + { ... + request_dump(mysql, ...); + ... + } + + int request_dump(MYSQL* mysql, ...) + { ... + if (opt_log_slave_updates && + mi->io_thd->variables.binlog_annotate_rows_events) + binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; + ... + int2store(buf + 4, binlog_flags); + ... + simple_command(mysql, COM_BINLOG_DUMP, buf, ...); + ... + } + +6. How master executes the request +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + case COM_BINLOG_DUMP: + { ... + flags= uint2korr(packet + 4); + ... + mysql_binlog_send(thd, ..., flags); + ... + } + + void mysql_binlog_send(THD* thd, ..., ushort flags) + { ... + Log_event::read_log_event(&log, packet, ...); + ... + if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || + flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || + thd->server_id == 0 /* slave == mysqlbinlog */ ) + { + my_net_write(net, packet->ptr(), packet->length()); + } + ... + } + +7. How slave SQL thread processes Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The slave processes each recieved event by "applying" it, i.e. by +calling the Log_event::apply_event() function which in turn calls +the virtual do_apply_event() member specific for each type of the +event. + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev = next_event(rli); + ... + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + + int apply_event_and_update_pos(Log_event *ev, ...) + { ... + ev->apply_event(...); + ... + } + + int Log_event::apply_event(...) + { + return do_apply_event(...); + } + +What does it mean to "apply" an Annotate_rows event? It means to set current +thd query to that of the described by the event, i.e. to the query which +caused the subsequent Rows events (see "How Master writes Annotate_rows +events to the binary log" to follow what happens further when the subsequent +Rows events is applied): + + int Annotate_rows_log_event::do_apply_event(...) + { + thd->set_query(m_query_txt, m_query_len); + } + +NOTE. I am not sure, but possibly current values of thd->query and +thd->query_length should be saved before calling set_query() and to be +restored on the Annotate_rows_log_event object deletion. +Is it really needed ? + +After calling this do_apply_event() function we may not delete the +Annotate_rows_log_event object immediatedly (see exec_relay_log_event() +above) because thd->query now points to the string inside this object. +We may keep the pointer to this object in the Relay_log_info: + + class Relay_log_info + { + public: + ... + void set_annotate_event(Annotate_rows_log_event*); + Annotate_rows_log_event* get_annotate_event(); + void free_annotate_event(); + ... + private: + Annotate_rows_log_event* m_annotate_event; + }; + +When the saved Annotate_rows object may be deleted? When all corresponding +Rows events will be processed, i.e. before processing the first non-Rows +event (note that Annotate_rows object resides in the binary log *after* +the (possible) 'BEGIN' Query event which accompanies the rows events; note +also that this deletion is adjusted with the case when some or all +corresponding Rows events are filtered out by replicate filter rules): + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev= next_event(rli); + ... + if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) + rli->free_annotate_event(); + + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) + rli->set_annotate_event((Annotate_rows_log_event*) ev); + else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + +where + + #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ + (type) == WRITE_ROWS_EVENT || \ + (type) == UPDATE_ROWS_EVENT || \ + (type) == DELETE_ROWS_EVENT ) + +8. General remarks +~~~~~~~~~~~~~~~~~~ +Kristian noticed that introducing new log event type should be coordinated +somehow with MySQL/Sun: + + Kristian: The numeric code for this event must be assigned carefully. + It should be coordinated with MySQL/Sun, otherwise we can get into a + situation where MySQL uses the same numeric code for one event that + MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two + impossible. + Alex: I reserved about 20 numbers not to have possible conflicts + with MySQL. + Kristian: Still, I think it would be appropriate to send a polite email + to internals(a)lists.mysql.com about this and suggesting to reserve the + event number. + +Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT +flag taking into account that MySQL/Sun may also introduce a flag with the +same value to be used in the request_dump-mysql_binlog_send interface. +But this is mainly the question of merging: if a conflict concerning this +flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value +(this does not require additional changes in the code). -=-=(Alexi - Sat, 19 Dec 2009, 15:41)=-=- High-Level Specification modified. --- /tmp/wklog.47.old.14545 2009-12-19 15:41:21.000000000 +0200 +++ /tmp/wklog.47.new.14545 2009-12-19 15:41:21.000000000 +0200 @@ -1,122 +1,107 @@ -First suggestion: - -> I think for this we would actually need a new binlog event type -> (Comment_log_event?).

Example: ************************ ANNOTATE_ROWS_EVENT ************************ 00000220 | B6 A0 2C 4B | time_when = 1261215926 00000224 | 33 | event_type = 51 00000225 | 64 00 00 00 | server_id = 100 00000229 | 36 00 00 00 | event_len = 54 0000022D | 56 02 00 00 | log_pos = 00000256 00000231 | 00 00 | flags = <none> ------------------------ 00000233 | 49 4E 53 45 | query = "INSERT INTO t1 VALUES (1), (2), (3)" 00000237 | 52 54 20 49 | 0000023B | 4E 54 4F 20 | 0000023F | 74 31 20 56 | 00000243 | 41 4C 55 45 | 00000247 | 53 20 28 31 | 0000024B | 29 2C 20 28 | 0000024F | 32 29 2C 20 | 00000253 | 28 33 29 | ************************ In binary log, Annotate_rows event follows the (possible) 'BEGIN' Query event and precedes the first of Table map events which accompany the corresponding rows events. (See example in the "mysqlbinlog output" section below.) 2. Server option: --binlog-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Tells the master to write Annotate_rows events to the binary log. * Variable Name: binlog_annotate_rows_events * Scope: Global & Session * Access Type: Dynamic * Data Type: bool * Default Value: OFF NOTE. Session values allows to annotate only some selected statements: ... SET SESSION binlog_annotate_rows_events=ON; ... statements to be annotated ... SET SESSION binlog_annotate_rows_events=OFF; ... statements not to be annotated ... 3. Server option: --replicate-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Tells the slave to reproduce Annotate_rows events recieved from the master in its own binary log (sensible only in pair with log-slave-updates option). * Variable Name: replicate_annotate_rows_events * Scope: Global * Access Type: Read only * Data Type: bool * Default Value: OFF NOTE. Why do we additionally need this 'replicate' option? Why not to make the slave to reproduce this events when its binlog-annotate-rows-events global value is ON? Well, because, for example, we may want to configure the slave which should reproduce Annotate_rows events but has global binlog-annotate-rows-events = OFF meaning this to be the default value for the client threads (see also "How slave treats replicate-annotate-rows-events option" in LLD part). 4. mysqlbinlog option: --print-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ With this option, mysqlbinlog prints the content of Annotate_rows events (if the binary log does contain them). Without this option (i.e. by default), mysqlbinlog skips Annotate_rows events. 5. mysqlbinlog output ~~~~~~~~~~~~~~~~~~~~~ With --print-annotate-rows-events, mysqlbinlog outputs Annotate_rows events in a form like this: ... # at 1646 #091219 12:45:26 server id 100 end_log_pos 1714 Query thread_id=1 exec_time=0 error_code=0 SET TIMESTAMP=1261215926/*!*/; BEGIN /*!*/; # at 1714 # at 1812 # at 1853 # at 1894 # at 1938 #091219 12:45:26 server id 100 end_log_pos 1812 Query: `DELETE t1, t2 FROM t1 INNER JOIN t2 INNER JOIN t3 WHERE t1.a=t2.a AND t2.a=t3.a` #091219 12:45:26 server id 100 end_log_pos 1853 Table_map: `test`.`t1` mapped to number 16 #091219 12:45:26 server id 100 end_log_pos 1894 Table_map: `test`.`t2` mapped to number 17 #091219 12:45:26 server id 100 end_log_pos 1938 Delete_rows: table id 16 #091219 12:45:26 server id 100 end_log_pos 1982 Delete_rows: table id 17 flags: STMT_END_F ...

How slave SQL thread processes Annotate_rows events 8. General remarks 1. Annotate_rows event number ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To avoid possible event numbers conflict with MySQL/Sun, we leave a gap between the last MySQL event number and the Annotate_rows event number: enum Log_event_type { ... INCIDENT_EVENT= 26, // New MySQL event numbers are to be added here MYSQL_EVENTS_END, MARIA_EVENTS_BEGIN= 51, // New Maria event numbers start from here ANNOTATE_ROWS_EVENT= 51, ENUM_END_EVENT }; together with the corresponding extension of 'post_header_len' array in the Format description event. (This extension does not affect the compatibility of the binary log). Here is how Format description event looks like with this extension: ************************ FORMAT_DESCRIPTION_EVENT ************************ 00000004 | A1 A0 2C 4B | time_when = 1261215905 00000008 | 0F | event_type = 15 00000009 | 64 00 00 00 | server_id = 100 0000000D | 7F 00 00 00 | event_len = 127 00000011 | 83 00 00 00 | log_pos = 00000083 00000015 | 01 00 | flags = LOG_EVENT_BINLOG_IN_USE_F ------------------------ 00000017 | 04 00 | binlog_ver = 4 00000019 | 35 2E 32 2E | server_ver = 5.2.0-MariaDB-alpha-debug-log ..... ... 0000004B | A1 A0 2C 4B | time_created = 1261215905 0000004F | 13 | common_header_len = 19 ------------------------ post_header_len ------------------------ 00000050 | 38 | 56 - START_EVENT_V3 [1] ..... ... 00000069 | 02 | 2 - INCIDENT_EVENT [26] 0000006A | 00 | 0 - RESERVED [27] ..... ... 00000081 | 00 | 0 - RESERVED [50] 00000082 | 00 | 0 - ANNOTATE_ROWS_EVENT [51] ************************ 2. Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || thd->server_id == 0 /* slave == mysqlbinlog */ ) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events are applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; When the saved Annotate_rows object may be deleted? When all corresponding Rows events will be processed, i.e. before processing the first non-Rows event (note that Annotate_rows object resides in the binary log *after* the (possible) 'BEGIN' Query event which accompanies the rows events; note also that this deletion is adjusted with the case when some or all corresponding Rows events are filtered out by replicate filter rules): int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) rli->free_annotate_event(); apply_event_and_update_pos(ev, ...); if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ (type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT ) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

This setting is done during initialization of these threads: + + pthread_handler_t handle_slave_io(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_IO); + ... + } + + pthread_handler_t handle_slave_sql(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_SQL); + ... + } + + int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) + { ... + thd->variables.binlog_annotate_rows_events= + opt_replicate_annotate_rows_events; + ... + } + +5. How slave IO thread requests Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +When requesting an event, the slave should inform the master whether +it should send Annotate_rows events or not. To that end we add a new +BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: + + #define BINLOG_DUMP_NON_BLOCK 1 + #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 + + pthread_handler_t handle_slave_io(void *arg) + { ... + request_dump(mysql, ...); + ... + } + + int request_dump(MYSQL* mysql, ...) + { ... + if (opt_log_slave_updates && + mi->io_thd->variables.binlog_annotate_rows_events) + binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; + ... + int2store(buf + 4, binlog_flags); + ... + simple_command(mysql, COM_BINLOG_DUMP, buf, ...); + ... + } + +6. How master executes the request +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + case COM_BINLOG_DUMP: + { ... + flags= uint2korr(packet + 4); + ... + mysql_binlog_send(thd, ..., flags); + ... + } + + void mysql_binlog_send(THD* thd, ..., ushort flags) + { ... + Log_event::read_log_event(&log, packet, ...); + ... + if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || + flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || + thd->server_id == 0 /* slave == mysqlbinlog */ ) + { + my_net_write(net, packet->ptr(), packet->length()); + } + ... + } + +7. How slave SQL thread processes Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The slave processes each recieved event by "applying" it, i.e. by +calling the Log_event::apply_event() function which in turn calls +the virtual do_apply_event() member specific for each type of the +event. + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev = next_event(rli); + ... + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + + int apply_event_and_update_pos(Log_event *ev, ...) + { ... + ev->apply_event(...); + ... + } + + int Log_event::apply_event(...) + { + return do_apply_event(...); + } + +What does it mean to "apply" an Annotate_rows event? It means to set current +thd query to that of the described by the event, i.e. to the query which +caused the subsequent Rows events (see "How Master writes Annotate_rows +events to the binary log" to follow what happens further when the subsequent +Rows events is applied): + + int Annotate_rows_log_event::do_apply_event(...) + { + thd->set_query(m_query_txt, m_query_len); + } + +NOTE. I am not sure, but possibly current values of thd->query and +thd->query_length should be saved before calling set_query() and to be +restored on the Annotate_rows_log_event object deletion. +Is it really needed ? + +After calling this do_apply_event() function we may not delete the +Annotate_rows_log_event object immediatedly (see exec_relay_log_event() +above) because thd->query now points to the string inside this object. +We may keep the pointer to this object in the Relay_log_info: + + class Relay_log_info + { + public: + ... + void set_annotate_event(Annotate_rows_log_event*); + Annotate_rows_log_event* get_annotate_event(); + void free_annotate_event(); + ... + private: + Annotate_rows_log_event* m_annotate_event; + }; + +When the saved Annotate_rows object may be deleted? When all corresponding +Rows events will be processed, i.e. before processing the first non-Rows +event (note that Annotate_rows object resides in the binary log *after* +the (possible) 'BEGIN' Query event which accompanies the rows events; note +also that this deletion is adjusted with the case when some or all +corresponding Rows events are filtered out by replicate filter rules): + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev= next_event(rli); + ... + if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) + rli->free_annotate_event(); + + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) + rli->set_annotate_event((Annotate_rows_log_event*) ev); + else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + +where + + #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ + (type) == WRITE_ROWS_EVENT || \ + (type) == UPDATE_ROWS_EVENT || \ + (type) == DELETE_ROWS_EVENT ) + +8. General remarks +~~~~~~~~~~~~~~~~~~ +Kristian noticed that introducing new log event type should be coordinated +somehow with MySQL/Sun: + + Kristian: The numeric code for this event must be assigned carefully. + It should be coordinated with MySQL/Sun, otherwise we can get into a + situation where MySQL uses the same numeric code for one event that + MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two + impossible. + Alex: I reserved about 20 numbers not to have possible conflicts + with MySQL. + Kristian: Still, I think it would be appropriate to send a polite email + to internals(a)lists.mysql.com about this and suggesting to reserve the + event number. + +Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT +flag taking into account that MySQL/Sun may also introduce a flag with the +same value to be used in the request_dump-mysql_binlog_send interface. +But this is mainly the question of merging: if a conflict concerning this +flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value +(this does not require additional changes in the code). -=-=(Alexi - Sat, 19 Dec 2009, 15:41)=-=- High-Level Specification modified. --- /tmp/wklog.47.old.14545 2009-12-19 15:41:21.000000000 +0200 +++ /tmp/wklog.47.new.14545 2009-12-19 15:41:21.000000000 +0200 @@ -1,122 +1,107 @@ -First suggestion: - -> I think for this we would actually need a new binlog event type -> (Comment_log_event?).

Without this option (i.e. by default), mysqlbinlog skips Annotate_rows events. 5. mysqlbinlog output ~~~~~~~~~~~~~~~~~~~~~ With --print-annotate-rows-events, mysqlbinlog outputs Annotate_rows events in a form like this: ... # at 1646 #091219 12:45:26 server id 100 end_log_pos 1714 Query thread_id=1 exec_time=0 error_code=0 SET TIMESTAMP=1261215926/*!*/; BEGIN /*!*/; # at 1714 # at 1812 # at 1853 # at 1894 # at 1938 #091219 12:45:26 server id 100 end_log_pos 1812 Query: `DELETE t1, t2 FROM t1 INNER JOIN t2 INNER JOIN t3 WHERE t1.a=t2.a AND t2.a=t3.a` #091219 12:45:26 server id 100 end_log_pos 1853 Table_map: `test`.`t1` mapped to number 16 #091219 12:45:26 server id 100 end_log_pos 1894 Table_map: `test`.`t2` mapped to number 17 #091219 12:45:26 server id 100 end_log_pos 1938 Delete_rows: table id 16 #091219 12:45:26 server id 100 end_log_pos 1982 Delete_rows: table id 17 flags: STMT_END_F ...

Annotate_rows event number ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To avoid possible event numbers conflict with MySQL/Sun, we leave a gap between the last MySQL event number and the Annotate_rows event number: enum Log_event_type { ... INCIDENT_EVENT= 26, // New MySQL event numbers are to be added here MYSQL_EVENTS_END, MARIA_EVENTS_BEGIN= 51, // New Maria event numbers start from here ANNOTATE_ROWS_EVENT= 51, ENUM_END_EVENT }; together with the corresponding extension of 'post_header_len' array in the Format description event. (This extension does not affect the compatibility of the binary log). Here is how Format description event looks like with this extension: ************************ FORMAT_DESCRIPTION_EVENT ************************ 00000004 | A1 A0 2C 4B | time_when = 1261215905 00000008 | 0F | event_type = 15 00000009 | 64 00 00 00 | server_id = 100 0000000D | 7F 00 00 00 | event_len = 127 00000011 | 83 00 00 00 | log_pos = 00000083 00000015 | 01 00 | flags = LOG_EVENT_BINLOG_IN_USE_F ------------------------ 00000017 | 04 00 | binlog_ver = 4 00000019 | 35 2E 32 2E | server_ver = 5.2.0-MariaDB-alpha-debug-log ..... ... 0000004B | A1 A0 2C 4B | time_created = 1261215905 0000004F | 13 | common_header_len = 19 ------------------------ post_header_len ------------------------ 00000050 | 38 | 56 - START_EVENT_V3 [1] ..... ... 00000069 | 02 | 2 - INCIDENT_EVENT [26] 0000006A | 00 | 0 - RESERVED [27] ..... ... 00000081 | 00 | 0 - RESERVED [50] 00000082 | 00 | 0 - ANNOTATE_RBR_EVENT [51] ************************ 2. Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || thd->server_id == 0 /* slave == mysqlbinlog */ ) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events are applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; When the saved Annotate_rows object may be deleted? When all corresponding Rows events will be processed, i.e. before processing the first non-Rows event (note that Annotate_rows object resides in the binary log *after* the (possible) 'BEGIN' Query event which accompanies the rows events; note also that this deletion is adjusted with the case when some or all corresponding Rows events are filtered out by replicate filter rules): int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) rli->free_annotate_event(); apply_event_and_update_pos(ev, ...); if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ (type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT ) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || thd->server_id == 0 /* slave == mysqlbinlog */ ) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events are applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; When the saved Annotate_rows object may be deleted? When all corresponding Rows events will be processed, i.e. before processing the first non-Rows event (note that Annotate_rows object resides in the binary log *after* the (possible) 'BEGIN' Query event which accompanies the rows events; note also that this deletion is adjusted with the case when some or all corresponding Rows events are filtered out by replicate filter rules): int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) rli->free_annotate_event(); apply_event_and_update_pos(ev, ...); if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ (type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT ) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

(This extension does not affect the compatibility of the binary log). Here is how Format description event looks like with this extension: ************************ FORMAT_DESCRIPTION_EVENT ************************ 00000004 | A1 A0 2C 4B | time_when = 1261215905 00000008 | 0F | event_type = 15 00000009 | 64 00 00 00 | server_id = 100 0000000D | 7F 00 00 00 | event_len = 127 00000011 | 83 00 00 00 | log_pos = 00000083 00000015 | 01 00 | flags = LOG_EVENT_BINLOG_IN_USE_F ------------------------ 00000017 | 04 00 | binlog_ver = 4 00000019 | 35 2E 32 2E | server_ver = 5.2.0-MariaDB-alpha-debug-log ..... ... 0000004B | A1 A0 2C 4B | time_created = 1261215905 0000004F | 13 | common_header_len = 19 ------------------------ post_header_len ------------------------ 00000050 | 38 | 56 - START_EVENT_V3 [1] ..... ... 00000069 | 02 | 2 - INCIDENT_EVENT [26] 0000006A | 00 | 0 - RESERVED [27] ..... ... 00000081 | 00 | 0 - RESERVED [50] 00000082 | 00 | 0 - ANNOTATE_RBR_EVENT [51] ************************ 2. Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || thd->server_id == 0 /* slave == mysqlbinlog */ ) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events are applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; When the saved Annotate_rows object may be deleted? When all corresponding Rows events will be processed, i.e. before processing the first non-Rows event (note that Annotate_rows object resides in the binary log *after* the (possible) 'BEGIN' Query event which accompanies the rows events; note also that this deletion is adjusted with the case when some or all corresponding Rows events are filtered out by replicate filter rules): int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ...

General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

Outline of Annotate_rows event behavior +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Each Annotate_rows_log_event object has two private members describing the +corresponding query: + + char *m_query_txt; + uint m_query_len; + +When the object is created for writing to a binary log, this query is taken +from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix +as well as other implementation details): + + Annotate_rows_log_event(THD *thd) + { + m_query_txt = thd->query(); + m_query_len = thd->query_length(); + } + +When the object is read from a binary log, the query is taken from the buffer +containing the binary log representation of the event (this buffer is allocated +in Log_event object from which all Log events are derived): + + Annotate_rows_log_event(char *buf, uint event_len, + Format_description_log_event *desc) + { + m_query_len = event_len - desc->common_header_len; + m_query_txt = buf + desc->common_header_len; + } + +The events are written to the binary log by the Log_event::write() member +which calls virtual write_data_header() and write_data_body() members +("data header" and "post header" are synonym in replication terminology). +In our case, data header is empty and data body is just the query: + + bool write_data_body(IO_CACHE *file) + { + return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); + } + +Printing the event is just printing the query: + + void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) + { + my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); + } + +3. How Master writes Annotate_rows events to the binary log +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The event is written to the binary log just before the group of Table_map +events which precede corresponding Rows events (one query may generate +several Table map events in the binary log, but the corresponding +Annotate_rows event must be written only once before the first Table map +event; hence the boolean variable 'with_annotate' below): + + int write_locked_table_maps(THD *thd) + { ... + bool with_annotate= thd->variables.binlog_annotate_rows_events; + ... + for (uint i= 0; i < ... <number of tables> ...; ++i) + { ... + thd->binlog_write_table_map(table, ..., with_annotate); + with_annotate= 0; // write Annotate_event not more than once + ... + } + ... + } + + int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) + { ... + Table_map_log_event the_event(...); + ... + if (with_annotate) + { + Annotate_rows_log_event anno(this); + mysql_bin_log.write(&anno); + } + + mysql_bin_log.write(&the_event); + ... + } + +4. How slave treats replicate-annotate-rows-events option +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The replicate-annotate-rows-events option is treated just as the session +value of the binlog_annotate_rows_events variable for the slave IO and +SQL threads. This setting is done during initialization of these threads: + + pthread_handler_t handle_slave_io(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_IO); + ... + } + + pthread_handler_t handle_slave_sql(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_SQL); + ... + } + + int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) + { ... + thd->variables.binlog_annotate_rows_events= + opt_replicate_annotate_rows_events; + ... + } + +5. How slave IO thread requests Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +When requesting an event, the slave should inform the master whether +it should send Annotate_rows events or not. To that end we add a new +BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: + + #define BINLOG_DUMP_NON_BLOCK 1 + #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 + + pthread_handler_t handle_slave_io(void *arg) + { ... + request_dump(mysql, ...); + ... + } + + int request_dump(MYSQL* mysql, ...) + { ... + if (opt_log_slave_updates && + mi->io_thd->variables.binlog_annotate_rows_events) + binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; + ... + int2store(buf + 4, binlog_flags); + ... + simple_command(mysql, COM_BINLOG_DUMP, buf, ...); + ... + } + +6. How master executes the request +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + case COM_BINLOG_DUMP: + { ... + flags= uint2korr(packet + 4); + ... + mysql_binlog_send(thd, ..., flags); + ... + } + + void mysql_binlog_send(THD* thd, ..., ushort flags) + { ... + Log_event::read_log_event(&log, packet, ...); + ... + if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || + flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || + thd->server_id == 0 /* slave == mysqlbinlog */ ) + { + my_net_write(net, packet->ptr(), packet->length()); + } + ... + } + +7. How slave SQL thread processes Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The slave processes each recieved event by "applying" it, i.e. by +calling the Log_event::apply_event() function which in turn calls +the virtual do_apply_event() member specific for each type of the +event. + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev = next_event(rli); + ... + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + + int apply_event_and_update_pos(Log_event *ev, ...) + { ... + ev->apply_event(...); + ... + } + + int Log_event::apply_event(...) + { + return do_apply_event(...); + } + +What does it mean to "apply" an Annotate_rows event? It means to set current +thd query to that of the described by the event, i.e. to the query which +caused the subsequent Rows events (see "How Master writes Annotate_rows +events to the binary log" to follow what happens further when the subsequent +Rows events is applied): + + int Annotate_rows_log_event::do_apply_event(...) + { + thd->set_query(m_query_txt, m_query_len); + } + +NOTE. I am not sure, but possibly current values of thd->query and +thd->query_length should be saved before calling set_query() and to be +restored on the Annotate_rows_log_event object deletion. +Is it really needed ? + +After calling this do_apply_event() function we may not delete the +Annotate_rows_log_event object immediatedly (see exec_relay_log_event() +above) because thd->query now points to the string inside this object. +We may keep the pointer to this object in the Relay_log_info: + + class Relay_log_info + { + public: + ... + void set_annotate_event(Annotate_rows_log_event*); + Annotate_rows_log_event* get_annotate_event(); + void free_annotate_event(); + ... + private: + Annotate_rows_log_event* m_annotate_event; + }; + +When the saved Annotate_rows object may be deleted? When all corresponding +Rows events will be processed, i.e. before processing the first non-Rows +event (note that Annotate_rows object resides in the binary log *after* +the (possible) 'BEGIN' Query event which accompanies the rows events; note +also that this deletion is adjusted with the case when some or all +corresponding Rows events are filtered out by replicate filter rules): + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev= next_event(rli); + ... + if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) + rli->free_annotate_event(); + + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) + rli->set_annotate_event((Annotate_rows_log_event*) ev); + else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + +where + + #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ + (type) == WRITE_ROWS_EVENT || \ + (type) == UPDATE_ROWS_EVENT || \ + (type) == DELETE_ROWS_EVENT ) + +8.

Server option: --replicate-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Tells the slave to reproduce Annotate_rows events recieved from the master in its own binary log (sensible only in pair with log-slave-updates option). * Variable Name: replicate_annotate_rows_events * Scope: Global * Access Type: Read only * Data Type: bool * Default Value: OFF NOTE. Why do we additionally need this 'replicate' option? Why not to make the slave to reproduce this events when its binlog-annotate-rows-events global value is ON? Well, because, for example, we may want to configure the slave which should reproduce Annotate_rows events but has global binlog-annotate-rows-events = OFF meaning this to be the default value for the client threads (see also "How slave treats replicate-annotate-rows-events option" in LLD part). 4. mysqlbinlog option: --print-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ With this option, mysqlbinlog prints the content of Annotate_rows events (if the binary log does contain them).

(This extension does not affect the compatibility of the binary log). Here is how Format description event looks like with this extension: ************************ FORMAT_DESCRIPTION_EVENT ************************ 00000004 | A1 A0 2C 4B | time_when = 1261215905 00000008 | 0F | event_type = 15 00000009 | 64 00 00 00 | server_id = 100 0000000D | 7F 00 00 00 | event_len = 127 00000011 | 83 00 00 00 | log_pos = 00000083 00000015 | 01 00 | flags = LOG_EVENT_BINLOG_IN_USE_F ------------------------ 00000017 | 04 00 | binlog_ver = 4 00000019 | 35 2E 32 2E | server_ver = 5.2.0-MariaDB-alpha-debug-log ..... ... 0000004B | A1 A0 2C 4B | time_created = 1261215905 0000004F | 13 | common_header_len = 19 ------------------------ post_header_len ------------------------ 00000050 | 38 | 56 - START_EVENT_V3 [1] ..... ... 00000069 | 02 | 2 - INCIDENT_EVENT [26] 0000006A | 00 | 0 - RESERVED [27] ..... ... 00000081 | 00 | 0 - RESERVED [50] 00000082 | 00 | 0 - ANNOTATE_RBR_EVENT [51] ************************ 2. Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || thd->server_id == 0 /* slave == mysqlbinlog */ ) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events is applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; When the saved Annotate_rows object may be deleted? When all corresponding Rows events will be processed, i.e. before processing the first non-Rows event (note that Annotate_rows object resides in the binary log *after* the (possible) 'BEGIN' Query event which accompanies the rows events; note also that this deletion is adjusted with the case when some or all corresponding Rows events are filtered out by replicate filter rules): int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) rli->free_annotate_event(); apply_event_and_update_pos(ev, ...); if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ (type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT ) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

How Master writes Annotate_rows events to the binary log +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The event is written to the binary log just before the group of Table_map +events which precede corresponding Rows events (one query may generate +several Table map events in the binary log, but the corresponding +Annotate_rows event must be written only once before the first Table map +event; hence the boolean variable 'with_annotate' below): + + int write_locked_table_maps(THD *thd) + { ... + bool with_annotate= thd->variables.binlog_annotate_rows_events; + ... + for (uint i= 0; i < ... <number of tables> ...; ++i) + { ... + thd->binlog_write_table_map(table, ..., with_annotate); + with_annotate= 0; // write Annotate_event not more than once + ... + } + ... + } + + int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) + { ... + Table_map_log_event the_event(...); + ... + if (with_annotate) + { + Annotate_rows_log_event anno(this); + mysql_bin_log.write(&anno); + } + + mysql_bin_log.write(&the_event); + ... + } + +4. How slave treats replicate-annotate-rows-events option +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The replicate-annotate-rows-events option is treated just as the session +value of the binlog_annotate_rows_events variable for the slave IO and +SQL threads. This setting is done during initialization of these threads: + + pthread_handler_t handle_slave_io(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_IO); + ... + } + + pthread_handler_t handle_slave_sql(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_SQL); + ... + } + + int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) + { ... + thd->variables.binlog_annotate_rows_events= + opt_replicate_annotate_rows_events; + ... + } + +5. How slave IO thread requests Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +When requesting an event, the slave should inform the master whether +it should send Annotate_rows events or not. To that end we add a new +BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: + + #define BINLOG_DUMP_NON_BLOCK 1 + #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 + + pthread_handler_t handle_slave_io(void *arg) + { ... + request_dump(mysql, ...); + ... + } + + int request_dump(MYSQL* mysql, ...) + { ... + if (opt_log_slave_updates && + mi->io_thd->variables.binlog_annotate_rows_events) + binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; + ... + int2store(buf + 4, binlog_flags); + ... + simple_command(mysql, COM_BINLOG_DUMP, buf, ...); + ... + } + +6. How master executes the request +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + case COM_BINLOG_DUMP: + { ... + flags= uint2korr(packet + 4); + ... + mysql_binlog_send(thd, ..., flags); + ... + } + + void mysql_binlog_send(THD* thd, ..., ushort flags) + { ... + Log_event::read_log_event(&log, packet, ...); + ... + if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || + flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || + thd->server_id == 0 /* slave == mysqlbinlog */ ) + { + my_net_write(net, packet->ptr(), packet->length()); + } + ... + } + +7. How slave SQL thread processes Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The slave processes each recieved event by "applying" it, i.e. by +calling the Log_event::apply_event() function which in turn calls +the virtual do_apply_event() member specific for each type of the +event. + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev = next_event(rli); + ... + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + + int apply_event_and_update_pos(Log_event *ev, ...) + { ... + ev->apply_event(...); + ... + } + + int Log_event::apply_event(...) + { + return do_apply_event(...); + } + +What does it mean to "apply" an Annotate_rows event? It means to set current +thd query to that of the described by the event, i.e. to the query which +caused the subsequent Rows events (see "How Master writes Annotate_rows +events to the binary log" to follow what happens further when the subsequent +Rows events is applied): + + int Annotate_rows_log_event::do_apply_event(...) + { + thd->set_query(m_query_txt, m_query_len); + } + +NOTE. I am not sure, but possibly current values of thd->query and +thd->query_length should be saved before calling set_query() and to be +restored on the Annotate_rows_log_event object deletion. +Is it really needed ? + +After calling this do_apply_event() function we may not delete the +Annotate_rows_log_event object immediatedly (see exec_relay_log_event() +above) because thd->query now points to the string inside this object. +We may keep the pointer to this object in the Relay_log_info: + + class Relay_log_info + { + public: + ... + void set_annotate_event(Annotate_rows_log_event*); + Annotate_rows_log_event* get_annotate_event(); + void free_annotate_event(); + ... + private: + Annotate_rows_log_event* m_annotate_event; + }; + +When the saved Annotate_rows object may be deleted? When all corresponding +Rows events will be processed, i.e. before processing the first non-Rows +event (note that Annotate_rows object resides in the binary log *after* +the (possible) 'BEGIN' Query event which accompanies the rows events; note +also that this deletion is adjusted with the case when some or all +corresponding Rows events are filtered out by replicate filter rules): + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev= next_event(rli); + ... + if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) + rli->free_annotate_event(); + + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) + rli->set_annotate_event((Annotate_rows_log_event*) ev); + else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + +where + + #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ + (type) == WRITE_ROWS_EVENT || \ + (type) == UPDATE_ROWS_EVENT || \ + (type) == DELETE_ROWS_EVENT ) + +8. General remarks +~~~~~~~~~~~~~~~~~~ +Kristian noticed that introducing new log event type should be coordinated +somehow with MySQL/Sun: + + Kristian: The numeric code for this event must be assigned carefully. + It should be coordinated with MySQL/Sun, otherwise we can get into a + situation where MySQL uses the same numeric code for one event that + MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two + impossible. + Alex: I reserved about 20 numbers not to have possible conflicts + with MySQL. + Kristian: Still, I think it would be appropriate to send a polite email + to internals(a)lists.mysql.com about this and suggesting to reserve the + event number. + +Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT +flag taking into account that MySQL/Sun may also introduce a flag with the +same value to be used in the request_dump-mysql_binlog_send interface. +But this is mainly the question of merging: if a conflict concerning this +flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value +(this does not require additional changes in the code). -=-=(Alexi - Sat, 19 Dec 2009, 15:41)=-=- High-Level Specification modified. --- /tmp/wklog.47.old.14545 2009-12-19 15:41:21.000000000 +0200 +++ /tmp/wklog.47.new.14545 2009-12-19 15:41:21.000000000 +0200 @@ -1,122 +1,107 @@ -First suggestion: - -> I think for this we would actually need a new binlog event type -> (Comment_log_event?).

The cost of this can be that the binlog will be approximately 2x in size (especially insert of big blob's would be a bit painful), so this should be an optional feature.

Has empty post-header and contains the query text in its data part.

(See example in the "mysqlbinlog output" section below.) 2. Server option: --binlog-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Tells the master to write Annotate_rows events to the binary log. * Variable Name: binlog_annotate_rows_events * Scope: Global & Session * Access Type: Dynamic * Data Type: bool * Default Value: OFF NOTE. Session values allows to annotate only some selected statements: ... SET SESSION binlog_annotate_rows_events=ON; ... statements to be annotated ... SET SESSION binlog_annotate_rows_events=OFF; ... statements not to be annotated ... 3. Server option: --replicate-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Tells the slave to reproduce Annotate_rows events recieved from the master in its own binary log (sensible only in pair with log-slave-updates option). * Variable Name: replicate_annotate_rows_events * Scope: Global * Access Type: Read only * Data Type: bool * Default Value: OFF NOTE. Why do we additionally need this 'replicate' option? Why not to make the slave to reproduce this events when its binlog-annotate-rows-events global value is ON? Well, because, for example, we may want to configure the slave which should reproduce Annotate_rows events but has global binlog-annotate-rows-events = OFF meaning this to be the default value for the client threads (see also "How slave treats replicate-annotate-rows-events option" in LLD part). 4. mysqlbinlog option: --print-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ With this option, mysqlbinlog prints the content of Annotate_rows events (if the binary log does contain them). Without this option (i.e. by default), mysqlbinlog skips Annotate_rows events. 5. mysqlbinlog output ~~~~~~~~~~~~~~~~~~~~~ With --print-annotate-rows-events, mysqlbinlog outputs Annotate_rows events in a form like this: ... # at 1646 #091219 12:45:26 server id 100 end_log_pos 1714 Query thread_id=1 exec_time=0 error_code=0 SET TIMESTAMP=1261215926/*!*/; BEGIN /*!*/; # at 1714 # at 1812 # at 1853 # at 1894 # at 1938 #091219 12:45:26 server id 100 end_log_pos 1812 Query: `DELETE t1, t2 FROM t1 INNER JOIN t2 INNER JOIN t3 WHERE t1.a=t2.a AND t2.a=t3.a` #091219 12:45:26 server id 100 end_log_pos 1853 Table_map: `test`.`t1` mapped to number 16 #091219 12:45:26 server id 100 end_log_pos 1894 Table_map: `test`.`t2` mapped to number 17 #091219 12:45:26 server id 100 end_log_pos 1938 Delete_rows: table id 16 #091219 12:45:26 server id 100 end_log_pos 1982 Delete_rows: table id 17 flags: STMT_END_F ...

(This extension does not affect the compatibility of the binary log). Here is how Format description event looks like with this extension: ************************ FORMAT_DESCRIPTION_EVENT ************************ 00000004 | A1 A0 2C 4B | time_when = 1261215905 00000008 | 0F | event_type = 15 00000009 | 64 00 00 00 | server_id = 100 0000000D | 7F 00 00 00 | event_len = 127 00000011 | 83 00 00 00 | log_pos = 00000083 00000015 | 01 00 | flags = LOG_EVENT_BINLOG_IN_USE_F ------------------------ 00000017 | 04 00 | binlog_ver = 4 00000019 | 35 2E 32 2E | server_ver = 5.2.0-MariaDB-alpha-debug-log ..... ... 0000004B | A1 A0 2C 4B | time_created = 1261215905 0000004F | 13 | common_header_len = 19 ------------------------ post_header_len ------------------------ 00000050 | 38 | 56 - START_EVENT_V3 [1] ..... ... 00000069 | 02 | 2 - INCIDENT_EVENT [26] 0000006A | 00 | 0 - RESERVED [27] ..... ... 00000081 | 00 | 0 - RESERVED [50] 00000082 | 00 | 0 - ANNOTATE_RBR_EVENT [51] ************************ 2. Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || thd->server_id == 0 /* slave == mysqlbinlog */ ) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events is applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; When the saved Annotate_rows object may be deleted? When all corresponding Rows events will be processed, i.e. before processing the first non-Rows event (note that Annotate_rows object resides in the binary log *after* the (possible) 'BEGIN' Query event which accompanies the rows events; note also that this deletion is adjusted with the case when some or all corresponding Rows events are filtered out by replicate filter rules): int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) rli->free_annotate_event(); apply_event_and_update_pos(ev, ...); if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ (type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT ) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

I am not sure, but possibly current values of thd->query and +thd->query_length should be saved before calling set_query() and to be +restored on the Annotate_rows_log_event object deletion. +Is it really needed ? + +After calling this do_apply_event() function we may not delete the +Annotate_rows_log_event object immediatedly (see exec_relay_log_event() +above) because thd->query now points to the string inside this object. +We may keep the pointer to this object in the Relay_log_info: + + class Relay_log_info + { + public: + ... + void set_annotate_event(Annotate_rows_log_event*); + Annotate_rows_log_event* get_annotate_event(); + void free_annotate_event(); + ... + private: + Annotate_rows_log_event* m_annotate_event; + }; + +When the saved Annotate_rows object may be deleted? When all corresponding +Rows events will be processed, i.e. before processing the first non-Rows +event (note that Annotate_rows object resides in the binary log *after* +the (possible) 'BEGIN' Query event which accompanies the rows events; note +also that this deletion is adjusted with the case when some or all +corresponding Rows events are filtered out by replicate filter rules): + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev= next_event(rli); + ... + if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) + rli->free_annotate_event(); + + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) + rli->set_annotate_event((Annotate_rows_log_event*) ev); + else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + +where + + #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ + (type) == WRITE_ROWS_EVENT || \ + (type) == UPDATE_ROWS_EVENT || \ + (type) == DELETE_ROWS_EVENT ) + +8.

(This extension does not affect the compatibility of the binary log). Here is how Format description event looks like with this extension: ************************ FORMAT_DESCRIPTION_EVENT ************************ 00000004 | A1 A0 2C 4B | time_when = 1261215905 00000008 | 0F | event_type = 15 00000009 | 64 00 00 00 | server_id = 100 0000000D | 7F 00 00 00 | event_len = 127 00000011 | 83 00 00 00 | log_pos = 00000083 00000015 | 01 00 | flags = LOG_EVENT_BINLOG_IN_USE_F ------------------------ 00000017 | 04 00 | binlog_ver = 4 00000019 | 35 2E 32 2E | server_ver = 5.2.0-MariaDB-alpha-debug-log ..... ... 0000004B | A1 A0 2C 4B | time_created = 1261215905 0000004F | 13 | common_header_len = 19 ------------------------ post_header_len ------------------------ 00000050 | 38 | 56 - START_EVENT_V3 [1] ..... ... 00000069 | 02 | 2 - INCIDENT_EVENT [26] 0000006A | 00 | 0 - RESERVED [27] ..... ... 00000081 | 00 | 0 - RESERVED [50] 00000082 | 00 | 0 - ANNOTATE_RBR_EVENT [51] ************************ 2. Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || thd->server_id == 0 /* slave == mysqlbinlog */ ) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events is applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; When the saved Annotate_rows object may be deleted? When all corresponding Rows events will be processed, i.e. before processing the first non-Rows event (note that Annotate_rows object resides in the binary log *after* the (possible) 'BEGIN' Query event which accompanies the rows events; note also that this deletion is adjusted with the case when some or all corresponding Rows events are filtered out by replicate filter rules): int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) rli->free_annotate_event(); apply_event_and_update_pos(ev, ...); if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ (type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT ) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

(This extension does not affect the compatibility of the binary log). Here is how Format description event looks like with this extension: ************************ FORMAT_DESCRIPTION_EVENT ************************ 00000004 | A1 A0 2C 4B | time_when = 1261215905 00000008 | 0F | event_type = 15 00000009 | 64 00 00 00 | server_id = 100 0000000D | 7F 00 00 00 | event_len = 127 00000011 | 83 00 00 00 | log_pos = 00000083 00000015 | 01 00 | flags = LOG_EVENT_BINLOG_IN_USE_F ------------------------ 00000017 | 04 00 | binlog_ver = 4 00000019 | 35 2E 32 2E | server_ver = 5.2.0-MariaDB-alpha-debug-log ..... ... 0000004B | A1 A0 2C 4B | time_created = 1261215905 0000004F | 13 | common_header_len = 19 ------------------------ post_header_len ------------------------ 00000050 | 38 | 56 - START_EVENT_V3 [1] ..... ... 00000069 | 02 | 2 - INCIDENT_EVENT [26] 0000006A | 00 | 0 - RESERVED [27] ..... ... 00000081 | 00 | 0 - RESERVED [50] 00000082 | 00 | 0 - ANNOTATE_RBR_EVENT [51] ************************ 2. Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || thd->server_id == 0 /* slave == mysqlbinlog */ ) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events is applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; When the saved Annotate_rows object may be deleted? When all corresponding Rows events will be processed, i.e. before processing the first non-Rows event (note that Annotate_rows object resides in the binary log *after* the (possible) 'BEGIN' Query event which accompanies the rows events; note also that this deletion is adjusted with the case when some or all corresponding Rows events are filtered out by replicate filter rules): int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) rli->free_annotate_event(); apply_event_and_update_pos(ev, ...); if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ (type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT ) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

Outline of Annotate_rows event behavior +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Each Annotate_rows_log_event object has two private members describing the +corresponding query: + + char *m_query_txt; + uint m_query_len; + +When the object is created for writing to a binary log, this query is taken +from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix +as well as other implementation details): + + Annotate_rows_log_event(THD *thd) + { + m_query_txt = thd->query(); + m_query_len = thd->query_length(); + } + +When the object is read from a binary log, the query is taken from the buffer +containing the binary log representation of the event (this buffer is allocated +in Log_event object from which all Log events are derived): + + Annotate_rows_log_event(char *buf, uint event_len, + Format_description_log_event *desc) + { + m_query_len = event_len - desc->common_header_len; + m_query_txt = buf + desc->common_header_len; + } + +The events are written to the binary log by the Log_event::write() member +which calls virtual write_data_header() and write_data_body() members +("data header" and "post header" are synonym in replication terminology). +In our case, data header is empty and data body is just the query: + + bool write_data_body(IO_CACHE *file) + { + return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); + } + +Printing the event is just printing the query: + + void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) + { + my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); + } + +3. How Master writes Annotate_rows events to the binary log +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The event is written to the binary log just before the group of Table_map +events which precede corresponding Rows events (one query may generate +several Table map events in the binary log, but the corresponding +Annotate_rows event must be written only once before the first Table map +event; hence the boolean variable 'with_annotate' below): + + int write_locked_table_maps(THD *thd) + { ... + bool with_annotate= thd->variables.binlog_annotate_rows_events; + ... + for (uint i= 0; i < ... <number of tables> ...; ++i) + { ... + thd->binlog_write_table_map(table, ..., with_annotate); + with_annotate= 0; // write Annotate_event not more than once + ... + } + ... + } + + int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) + { ... + Table_map_log_event the_event(...); + ... + if (with_annotate) + { + Annotate_rows_log_event anno(this); + mysql_bin_log.write(&anno); + } + + mysql_bin_log.write(&the_event); + ... + } + +4. How slave treats replicate-annotate-rows-events option +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The replicate-annotate-rows-events option is treated just as the session +value of the binlog_annotate_rows_events variable for the slave IO and +SQL threads. This setting is done during initialization of these threads: + + pthread_handler_t handle_slave_io(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_IO); + ... + } + + pthread_handler_t handle_slave_sql(void *arg) + { + THD *thd= new THD; + ... + init_slave_thread(thd, SLAVE_THD_SQL); + ... + } + + int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) + { ... + thd->variables.binlog_annotate_rows_events= + opt_replicate_annotate_rows_events; + ... + } + +5. How slave IO thread requests Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +When requesting an event, the slave should inform the master whether +it should send Annotate_rows events or not. To that end we add a new +BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: + + #define BINLOG_DUMP_NON_BLOCK 1 + #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 + + pthread_handler_t handle_slave_io(void *arg) + { ... + request_dump(mysql, ...); + ... + } + + int request_dump(MYSQL* mysql, ...) + { ... + if (opt_log_slave_updates && + mi->io_thd->variables.binlog_annotate_rows_events) + binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; + ... + int2store(buf + 4, binlog_flags); + ... + simple_command(mysql, COM_BINLOG_DUMP, buf, ...); + ... + } + +6. How master executes the request +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + case COM_BINLOG_DUMP: + { ... + flags= uint2korr(packet + 4); + ... + mysql_binlog_send(thd, ..., flags); + ... + } + + void mysql_binlog_send(THD* thd, ..., ushort flags) + { ... + Log_event::read_log_event(&log, packet, ...); + ... + if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || + flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || + thd->server_id == 0 /* slave == mysqlbinlog */ ) + { + my_net_write(net, packet->ptr(), packet->length()); + } + ... + } + +7. How slave SQL thread processes Annotate_rows events +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The slave processes each recieved event by "applying" it, i.e. by +calling the Log_event::apply_event() function which in turn calls +the virtual do_apply_event() member specific for each type of the +event. + + int exec_relay_log_event(THD* thd, Relay_log_info* rli) + { ... + Log_event *ev = next_event(rli); + ... + apply_event_and_update_pos(ev, ...); + + if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) + delete ev; + ... + } + + int apply_event_and_update_pos(Log_event *ev, ...) + { ... + ev->apply_event(...); + ... + } + + int Log_event::apply_event(...) + { + return do_apply_event(...); + } + +What does it mean to "apply" an Annotate_rows event? It means to set current +thd query to that of the described by the event, i.e. to the query which +caused the subsequent Rows events (see "How Master writes Annotate_rows +events to the binary log" to follow what happens further when the subsequent +Rows events is applied): + + int Annotate_rows_log_event::do_apply_event(...) + { + thd->set_query(m_query_txt, m_query_len); + } + +NOTE. I am not sure, but possibly current values of thd->query and +thd->query_length should be saved before calling set_query() and to be +restored on the Annotate_rows_log_event object deletion. +Is it really needed ? + +After calling this do_apply_event() function we may not delete the +Annotate_rows_log_event object immediatedly (see exec_relay_log_event() +above) because thd->query now points to the string inside this object. +We may keep the pointer to this object in the Relay_log_info: + + class Relay_log_info + { + public: + ... + void set_annotate_event(Annotate_rows_log_event*); + Annotate_rows_log_event* get_annotate_event(); + void free_annotate_event(); + ... + private: + Annotate_rows_log_event* m_annotate_event; + }; + +When the saved Annotate_rows object may be deleted?

Why do we additionally need this 'replicate' option? Why not to make the slave to reproduce this events when its binlog-annotate-rows-events global value is ON? Well, because, for example, we may want to configure the slave which should reproduce Annotate_rows events but has global binlog-annotate-rows-events = OFF meaning this to be the default value for the client threads (see also "How slave treats replicate-annotate-rows-events option" in LLD part). 4. mysqlbinlog option: --print-annotate-rows-events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ With this option, mysqlbinlog prints the content of Annotate_rows events (if the binary log does contain them).

How slave SQL thread processes Annotate_rows events 8. General remarks 1. Annotate_rows event number ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To avoid possible event numbers conflict with MySQL/Sun, we leave a gap between the last MySQL event number and the Annotate_rows event number: enum Log_event_type { ... INCIDENT_EVENT= 26, // New MySQL event numbers are to be added here MYSQL_EVENTS_END, MARIA_EVENTS_BEGIN= 51, // New Maria event numbers start from here ANNOTATE_ROWS_EVENT= 51, ENUM_END_EVENT }; together with the corresponding extension of 'post_header_len' array in the Format description event. (This extension does not affect the compatibility of the binary log). Here is how Format description event looks like with this extension: ************************ FORMAT_DESCRIPTION_EVENT ************************ 00000004 | A1 A0 2C 4B | time_when = 1261215905 00000008 | 0F | event_type = 15 00000009 | 64 00 00 00 | server_id = 100 0000000D | 7F 00 00 00 | event_len = 127 00000011 | 83 00 00 00 | log_pos = 00000083 00000015 | 01 00 | flags = LOG_EVENT_BINLOG_IN_USE_F ------------------------ 00000017 | 04 00 | binlog_ver = 4 00000019 | 35 2E 32 2E | server_ver = 5.2.0-MariaDB-alpha-debug-log ..... ... 0000004B | A1 A0 2C 4B | time_created = 1261215905 0000004F | 13 | common_header_len = 19 ------------------------ post_header_len ------------------------ 00000050 | 38 | 56 - START_EVENT_V3 [1] ..... ... 00000069 | 02 | 2 - INCIDENT_EVENT [26] 0000006A | 00 | 0 - RESERVED [27] ..... ... 00000081 | 00 | 0 - RESERVED [50] 00000082 | 00 | 0 - ANNOTATE_RBR_EVENT [51] ************************ 2. Outline of Annotate_rows event behavior ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each Annotate_rows_log_event object has two private members describing the corresponding query: char *m_query_txt; uint m_query_len; When the object is created for writing to a binary log, this query is taken from 'thd' (for short, below we omit the 'Annotate_rows_log_event::' prefix as well as other implementation details): Annotate_rows_log_event(THD *thd) { m_query_txt = thd->query(); m_query_len = thd->query_length(); } When the object is read from a binary log, the query is taken from the buffer containing the binary log representation of the event (this buffer is allocated in Log_event object from which all Log events are derived): Annotate_rows_log_event(char *buf, uint event_len, Format_description_log_event *desc) { m_query_len = event_len - desc->common_header_len; m_query_txt = buf + desc->common_header_len; } The events are written to the binary log by the Log_event::write() member which calls virtual write_data_header() and write_data_body() members ("data header" and "post header" are synonym in replication terminology). In our case, data header is empty and data body is just the query: bool write_data_body(IO_CACHE *file) { return my_b_safe_write(file, (uchar*) m_query_txt, m_query_len); } Printing the event is just printing the query: void Annotate_rows_log_event::print(FILE *file, PRINT_EVENT_INFO *pinfo) { my_b_printf(&pinfo->head_cache, "\tQuery: `%s`\n", m_query_txt); } 3. How Master writes Annotate_rows events to the binary log ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The event is written to the binary log just before the group of Table_map events which precede corresponding Rows events (one query may generate several Table map events in the binary log, but the corresponding Annotate_rows event must be written only once before the first Table map event; hence the boolean variable 'with_annotate' below): int write_locked_table_maps(THD *thd) { ... bool with_annotate= thd->variables.binlog_annotate_rows_events; ... for (uint i= 0; i < ... <number of tables> ...; ++i) { ... thd->binlog_write_table_map(table, ..., with_annotate); with_annotate= 0; // write Annotate_event not more than once ... } ... } int THD::binlog_write_table_map(TABLE *table, ..., bool with_annotate) { ... Table_map_log_event the_event(...); ... if (with_annotate) { Annotate_rows_log_event anno(this); mysql_bin_log.write(&anno); } mysql_bin_log.write(&the_event); ... } 4. How slave treats replicate-annotate-rows-events option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The replicate-annotate-rows-events option is treated just as the session value of the binlog_annotate_rows_events variable for the slave IO and SQL threads. This setting is done during initialization of these threads: pthread_handler_t handle_slave_io(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_IO); ... } pthread_handler_t handle_slave_sql(void *arg) { THD *thd= new THD; ... init_slave_thread(thd, SLAVE_THD_SQL); ... } int init_slave_thread(THD* thd, SLAVE_THD_TYPE thd_type) { ... thd->variables.binlog_annotate_rows_events= opt_replicate_annotate_rows_events; ... } 5. How slave IO thread requests Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When requesting an event, the slave should inform the master whether it should send Annotate_rows events or not. To that end we add a new BINLOG_SEND_ANNOTATE_ROWS_EVENT flag used when requesting an event: #define BINLOG_DUMP_NON_BLOCK 1 #define BINLOG_SEND_ANNOTATE_ROWS_EVENT 2 pthread_handler_t handle_slave_io(void *arg) { ... request_dump(mysql, ...); ... } int request_dump(MYSQL* mysql, ...) { ... if (opt_log_slave_updates && mi->io_thd->variables.binlog_annotate_rows_events) binlog_flags|= BINLOG_SEND_ANNOTATE_ROWS_EVENT; ... int2store(buf + 4, binlog_flags); ... simple_command(mysql, COM_BINLOG_DUMP, buf, ...); ... } 6. How master executes the request ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ case COM_BINLOG_DUMP: { ... flags= uint2korr(packet + 4); ... mysql_binlog_send(thd, ..., flags); ... } void mysql_binlog_send(THD* thd, ..., ushort flags) { ... Log_event::read_log_event(&log, packet, ...); ... if ((*packet)[EVENT_TYPE_OFFSET + 1] != ANNOTATE_ROWS_EVENT || flags & BINLOG_SEND_ANNOTATE_ROWS_EVENT || thd->server_id == 0 /* slave == mysqlbinlog */ ) { my_net_write(net, packet->ptr(), packet->length()); } ... } 7. How slave SQL thread processes Annotate_rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The slave processes each recieved event by "applying" it, i.e. by calling the Log_event::apply_event() function which in turn calls the virtual do_apply_event() member specific for each type of the event. int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev = next_event(rli); ... apply_event_and_update_pos(ev, ...); if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } int apply_event_and_update_pos(Log_event *ev, ...) { ... ev->apply_event(...); ... } int Log_event::apply_event(...) { return do_apply_event(...); } What does it mean to "apply" an Annotate_rows event? It means to set current thd query to that of the described by the event, i.e. to the query which caused the subsequent Rows events (see "How Master writes Annotate_rows events to the binary log" to follow what happens further when the subsequent Rows events is applied): int Annotate_rows_log_event::do_apply_event(...) { thd->set_query(m_query_txt, m_query_len); } NOTE. I am not sure, but possibly current values of thd->query and thd->query_length should be saved before calling set_query() and to be restored on the Annotate_rows_log_event object deletion. Is it really needed ? After calling this do_apply_event() function we may not delete the Annotate_rows_log_event object immediatedly (see exec_relay_log_event() above) because thd->query now points to the string inside this object. We may keep the pointer to this object in the Relay_log_info: class Relay_log_info { public: ... void set_annotate_event(Annotate_rows_log_event*); Annotate_rows_log_event* get_annotate_event(); void free_annotate_event(); ... private: Annotate_rows_log_event* m_annotate_event; }; When the saved Annotate_rows object may be deleted? When all corresponding Rows events will be processed, i.e. before processing the first non-Rows event (note that Annotate_rows object resides in the binary log *after* the (possible) 'BEGIN' Query event which accompanies the rows events; note also that this deletion is adjusted with the case when some or all corresponding Rows events are filtered out by replicate filter rules): int exec_relay_log_event(THD* thd, Relay_log_info* rli) { ... Log_event *ev= next_event(rli); ... if (rli->get_annotate_event() && !IS_RBR_EVENT_TYPE(ev->get_type_code())) rli->free_annotate_event(); apply_event_and_update_pos(ev, ...); if (ev->get_type_code() == ANNOTATE_ROWS_EVENT) rli->set_annotate_event((Annotate_rows_log_event*) ev); else if (ev->get_type_code() != FORMAT_DESCRIPTION_EVENT) delete ev; ... } where #define IS_RBR_EVENT_TYPE(type) ( (type) == TABLE_MAP_EVENT || \ (type) == WRITE_ROWS_EVENT || \ (type) == UPDATE_ROWS_EVENT || \ (type) == DELETE_ROWS_EVENT ) 8. General remarks ~~~~~~~~~~~~~~~~~~ Kristian noticed that introducing new log event type should be coordinated somehow with MySQL/Sun: Kristian: The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Alex: I reserved about 20 numbers not to have possible conflicts with MySQL. Kristian: Still, I think it would be appropriate to send a polite email to internals(a)lists.mysql.com about this and suggesting to reserve the event number. Also we should notice the introduction of the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag taking into account that MySQL/Sun may also introduce a flag with the same value to be used in the request_dump-mysql_binlog_send interface. But this is mainly the question of merging: if a conflict concerning this flag occur, we may simply change the BINLOG_SEND_ANNOTATE_ROWS_EVENT value (this does not require additional changes in the code).

Without this option (i.e. by default), mysqlbinlog skips Annotate_rows events. 5. mysqlbinlog output ~~~~~~~~~~~~~~~~~~~~~ With --print-annotate-rows-events, mysqlbinlog outputs Annotate_rows events in a form like this: ... # at 1646 #091219 12:45:26 server id 100 end_log_pos 1714 Query thread_id=1 exec_time=0 error_code=0 SET TIMESTAMP=1261215926/*!*/; BEGIN /*!*/; # at 1714 # at 1812 # at 1853 # at 1894 # at 1938 #091219 12:45:26 server id 100 end_log_pos 1812 Query: `DELETE t1, t2 FROM t1 INNER JOIN t2 INNER JOIN t3 WHERE t1.a=t2.a AND t2.a=t3.a` #091219 12:45:26 server id 100 end_log_pos 1853 Table_map: `test`.`t1` mapped to number 16 #091219 12:45:26 server id 100 end_log_pos 1894 Table_map: `test`.`t2` mapped to number 17 #091219 12:45:26 server id 100 end_log_pos 1938 Delete_rows: table id 16 #091219 12:45:26 server id 100 end_log_pos 1982 Delete_rows: table id 17 flags: STMT_END_F ...

[Maria-developers] New (by Bothorsen): Fix table_cache negative scalability (73)

----------------------------------------------------------------------- WORKLOG TASK -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- TASK...........: Fix table_cache negative scalability CREATION DATE..: Fri, 18 Dec 2009, 16:31 SUPERVISOR.....: Bothorsen IMPLEMENTOR....: COPIES TO......: CATEGORY.......: Server-Sprint TASK ID........: 73 (http://askmonty.org/worklog/?tid=73) VERSION........: WorkLog-3.4 STATUS.........: Un-Assigned PRIORITY.......: 60 WORKED HOURS...: 0 ESTIMATE.......: 0 (hours remain) ORIG. ESTIMATE.: 0 PROGRESS NOTES: DESCRIPTION: Fix the problem described in this blog entry: http://www.mysqlperformanceblog.com/2009/11/16/table_cache-negative-scalabi… You can read the blog, or the text below. --- quoted text --- November 16, 2009 table_cache negative scalability Posted by peter | Vote on Planet MySQL Couple of months ago there was a post by FreshBooks on getting great performance improvements by lowering table_cache variable. So I decided to investigate what is really happening here. The common sense approach to tuning caches is to get them as large as you can if you have enough resources (such as memory). With MySQL common sense however does not always works weve seen performance issues with large query_cache_size also sort_buffer_size and read_buffer_size may not give you better performance if you increase them. I found this also applies to some other buffers. Even though having previous experience of surprised behavior I did not expect such a table_cache issue the LRU for cache management is classics and there are scalable algorithms to deal with it. I would expect Monty to implement one of them. To do the test I have created 100.000 empty tables containing single integer column and no indexes and when ran SELECT * FROM tableN in the loop. Each table in such case is accessed only once and on any but first run each access would require table replacement in table cache based on LRU logic. MySQL Sandbox helped me to test this with different servers easily. I did test on CentOS 5.3, Xeon E5405, 16GB RAM and EXT3 file system on the SATA hard drive. MySQL 5.0.85 Created 100.000 tables in around 3min 40 sec which is about 450 tables/sec This indicates the fsync is lying on this test system as default sync_frm option is used. With default table_cache=64 accessing all tables take 12 sec which is almost 8500 tables/sec which is a great speed. We can note significant writes to the disk during this read-only benchmark. Why ? Because for MyISAM tables table header has to be modified each time the table is opened. In this case the performance was so great because all 100.000 tables data (first block of index) was placed close by on disk as well as fully cached which made updates to headers very slow. In the production systems with table headers not in OS cache you often will see significantly low numbers 100 or less. With significantly larger table_cache=16384 (and appropriately adjusted number of open files) the same operation takes 660 seconds which is 151 tables/sec which is around 50 times slower. Wow. This is the slow down. We can see the load becomes very CPU bound in this case and it looks like some of the table_cache algorithms do not scale well. The absolute numbers are also very interesting 151 tables/sec is not that bad if you look at it as an absolute number. So if you tune table cache is normal case and is able to bring down your miss rate (opened_tables) to 10/sec or less by using large table_cache you should do so. However if you have so many tables you still see 100+ misses/sec while your data (at least table headers) is well cached so the cost of table cache miss is not very high, you may be better of with significantly reduced table cache size. The next step for me was to see if the problem was fixed in MySQL 5.1 in this version table_cache was significantly redone and split in table_open_cache and table_definition_cache and I assumed the behavior may be different as well. MySQL 5.1.40 I started testing with default table_open_cache=64 and table_definition_cache=256 the read took about 12 seconds very close to MySQL 5.0.85. As I increased table_definition_cache to 16384 result remained the same so this variable is not causing the bottleneck. However increasing table_open_cache to 16384 causes scan to take about 780 sec which is a bit worse than MySQL 5.0.85. So the problem is not fixed in MySQL 5.1, lets see how MySQL 5.4 behaves. MySQL 5.4.2 MySQL 5.4.2 has higher default table_open_cache so I took it down to 64 so we can compare apples to apples. It performs same as MySQL 5.0 and MySQL 5.1 with small table cache. With table_open_cache increased to 16384 the test took 750 seconds so the problem exists in MySQL 5.4 as well. So the problem is real and it is not fixed even in Performance focused MySQL 5.4. As we can see large table_cache (or table_open_cache_ values indeed can cause significant performance problems. Interesting enough Innodb has a very similar task of managing its own cache of file descriptors (set by innodb_open_files) As the time allows I should test if Heikki knows how to implement LRU properly so it does not have problem with large number. Well see. ESTIMATED WORK TIME ESTIMATED COMPLETION DATE ----------------------------------------------------------------------- WorkLog (v3.5.9)

Estimate unchanged. -=-=(Bothorsen - Fri, 18 Dec 2009, 16:21)=-=- Added the estimation time. Worked 5 hours and estimate 20 hours remain (original estimate increased by 25 hours). DESCRIPTION: Question: How much effort would be required to provide an "ORDER BY FIRST_JOIN.column" feature? We often do self-join queries and want to order them by index, i.e.: create table t1 (a int, b int, unique key 'by_a_b' (a, b))); select * from t1 x inner join t1 y on (x.b = y.b) where x.a=1 and y.a=2 order by (x|y).b desc limit 10; but it is only ordered by index if you order by the first table in the optimized join order, which could be either x or y depending on which is more selective. we don't want to force the join order because often one is far more selective than the other, but the only way to know what table to order by then is to explain the query first. if there was some way to tell mysql to just order by the first join in the optimized order, that would help us. sometimes we do this across tables too. both of these can be solved by rewriting the query to say "using" instead of "on" in which case we don't have to specify the table name of the column, just "order by b desc". but, we also want to be able to do exclusions, in which case an "on" is required and therefore we run into ambiguous column names: Monty answered: MySQL has an optimization where it knows that if x.b = y.b is used then it can replace x.b with y.b and y.b with x.b in the WHERE part MySQL however doesn't do it for the ORDER BY part and I don't think that should be very hard to do. Question continues: create table t2 (c int, b int, unique key 'by_c_b' (c, b))); select * from t1 x inner join t1 y using (b) left join t2 on (t2.c = 3 and t1.b = t2.b) where x.a=1 and y.a=2 and t2.c is null order by (x| y).b desc limit 10; if we were ordering ascending, i think we could just leave off the order by entirely in this case and it would happen to work since it's reading in index order. but the combination of requiring an "on" and descending sort leaves us unable to use these tricks. if we had either an "ORDER BY FIRST_JOIN.column" or some way to tell the server that 'b' is in fact joined as being equivalent across tables (except where it may be null from left joining) and that we shouldn't have to specify the table name at all, that would save us having to figure out the table from the explain. Monty answers: It may be that the eq-replacment we have would solve this.

We often do self-join queries and want to order them by index, i.e.: create table t1 (a int, b int, unique key 'by_a_b' (a, b))); select * from t1 x inner join t1 y on (x.b = y.b) where x.a=1 and y.a=2 order by (x|y).b desc limit 10; but it is only ordered by index if you order by the first table in the optimized join order, which could be either x or y depending on which is more selective. we don't want to force the join order because often one is far more selective than the other, but the only way to know what table to order by then is to explain the query first. if there was some way to tell mysql to just order by the first join in the optimized order, that would help us. sometimes we do this across tables too. both of these can be solved by rewriting the query to say "using" instead of "on" in which case we don't have to specify the table name of the column, just "order by b desc". but, we also want to be able to do exclusions, in which case an "on" is required and therefore we run into ambiguous column names: Monty answered: MySQL has an optimization where it knows that if x.b = y.b is used then it can replace x.b with y.b and y.b with x.b in the WHERE part MySQL however doesn't do it for the ORDER BY part and I don't think that should be very hard to do. Question continues: create table t2 (c int, b int, unique key 'by_c_b' (c, b))); select * from t1 x inner join t1 y using (b) left join t2 on (t2.c = 3 and t1.b = t2.b) where x.a=1 and y.a=2 and t2.c is null order by (x| y).b desc limit 10; if we were ordering ascending, i think we could just leave off the order by entirely in this case and it would happen to work since it's reading in index order. but the combination of requiring an "on" and descending sort leaves us unable to use these tricks. if we had either an "ORDER BY FIRST_JOIN.column" or some way to tell the server that 'b' is in fact joined as being equivalent across tables (except where it may be null from left joining) and that we shouldn't have to specify the table name at all, that would save us having to figure out the table from the explain. Monty answers: It may be that the eq-replacment we have would solve this.

HIGH-LEVEL SPECIFICATION: First suggestion: > I think for this we would actually need a new binlog event type > (Comment_log_event?). Unless we want to log an empty statement Query_log_event > containing only a comment (a bit of a hack). New server option ~~~~~~~~~~~~~~~~~ --binlog-annotate-rows-events Setting this option makes RBR (rows-) events in the binary log to be preceded by Annotate rows events (see below). The corresponding 'binlog_annotate_rows_events' system variable is dynamic and has both global and session values. Default global value is OFF. Note. Session values are usefull to make it possible to annotate only some selected statements: ... SET SESSION binlog_annotate_rows_events=ON; ... statements to be annotated ... SET SESSION binlog_annotate_rows_events=OFF; ... statements not to be annotated ... New binlog event type ~~~~~~~~~~~~~~~~~~~~~ Annotate_rows_log_event [ ANNOTATE_ROWS_EVENT ] Describes the query which caused the corresponding rows event. In binary log, precedes each Table_map_log_event. Contains empty post-header and the query text in its data part. The numeric code for this event must be assigned carefully. It should be coordinated with MySQL/Sun, otherwise we can get into a situation where MySQL uses the same numeric code for one event that MariaDB uses for ANNOTATE_ROWS_EVENT, which would make merging the two impossible. Example: ... ************************ ANNOTATE_ROWS_EVENT [51] ************************ 000000C7 | 54 1B 12 4B | time_when = 1259477844 000000CB | 33 | event_type = 51 000000CC | 64 00 00 00 | server_id = 100 000000D0 | 2C 00 00 00 | event_len = 44 000000D4 | F3 00 00 00 | log_pos = 000000F3 000000D8 | 00 00 | flags = <none> ------------------------ 000000DA | 69 6E 73 65 | query = "insert into t1 values (1)" 000000DE | 72 74 20 69 | 000000E2 | 6E 74 6F 20 | 000000E6 | 74 31 20 76 | 000000EA | 61 6C 75 65 | 000000EE | 73 20 28 31 | 000000F2 | 29 | ************************ TABLE_MAP_EVENT [19] ************************ 000000F3 | 54 1B 12 4B | time_when = 1259477844 000000F7 | 13 | event_type = 19 000000F8 | 64 00 00 00 | server_id = 100 000000FC | 29 00 00 00 | event_len = 41 00000100 | 1C 01 00 00 | log_pos = 0000011C 00000104 | 00 00 | flags = <none> ------------------------ ... ************************ WRITE_ROWS_EVENT [23] ************************ 0000011C | 54 1B 12 4B | time_when = 1259477844 00000120 | 17 | event_type = 23 00000121 | 64 00 00 00 | server_id = 100 00000125 | 22 00 00 00 | event_len = 34 00000129 | 3E 01 00 00 | log_pos = 0000013E 0000012D | 10 00 | flags = LOG_EVENT_UPDATE_TABLE_MAP_VERSION_F ------------------------ 0000012F | 0F 00 00 00 | table_id = 15 ... New mysqlbinlog option ~~~~~~~~~~~~~~~~~~~~~~ --print-annotate-rows-events With this option, mysqlbinlog prints the content of Annotate-rows events (if the binary log does contain them). Without this option (i.e. by default), mysqlbinlog skips Annotate rows events. mysqlbinlog output ~~~~~~~~~~~~~~~~~~ Something like this: ... # at 199 # at 243 # at 284 #091129 9:57:24 server id 100 end_log_pos 243 Query: `insert into t1 values (1)` #091129 9:57:24 server id 100 end_log_pos 284 Table_map: `test`.`t1` mapped to number 15 #091129 9:57:24 server id 100 end_log_pos 318 Write_rows: table id 15 flags: STMT_END_F BINLOG ' VBsSSzNkAAAALAAAAPMAAAAAAGluc2VydCBpbnRvIHQxIHZhbHVlcyAoMSk= VBsSSxNkAAAAKQAAABwBAAAAAA8AAAAAAAAABHRlc3QAAnQxAAEDAAE= VBsSSxdkAAAAIgAAAD4BAAAQAA8AAAAAAAEAAf/+AQAAAA== '/*!*/; ### INSERT INTO test.t1 ### SET ### @1=1 /* INT meta=0 nullable=1 is_null=0 */ ... When master sends Annotate rows events ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1. Master always sends Annotate_rows events to mysqlbinlog (in remote case). 2. Master sends Annotate_rows events to a slave only if the slave has both log-slave-updates and binlog-annotate-rows-events options set.

A separate repository makes sense to me, or maybe add > them to the MariaDB sources? Yes. I have for some time known we need a public repository with the tools we use for MariaDB development. So now I have created a project for this on Launchpad. Branch to push to: lp:mariadb-tools Project page: https://launchpad.net/mariadb-tools Wiki page: http://askmonty.org/wiki/index.php/Tools_for_MariaDB Everybody, please help by moving things from our internal bzr repo hasky:/usr/local/bzr into this project where relevant. And also please help by updating the wiki page with appropriate documentation. > I have a first working version of the wrapper scripts to automatically > run sql-bench with a set of different configurations. >From this description, it sounds like something that would make sense to include in the MariaDB source tree? If so, I guess just commit them and get a review. Generally, it is an advantage to keep tools that work on a specific version of MariaDB inside the source tree, especially for automation (like Buildbot). Eg. if different variants of the scripts are needed for different MariaDB versions (maybe using a feature that is not present in older versions); keeping the scripts inside the tree trivially ensures that the versions of scripts and of MariaDB matches. It also removes any issues wiht making sure the scripts are available on a given host. On the other hand, if the script needs to work with different versions of MariaDB it probably makes sense to keep it outside of the main source tree. Maybe the script needs to check out the MariaDB source tree (like package scripts); it cannot easily checkout itself... Or maybe it needs to compare two different versions of MariaDB against each other (benchmarks, upgrade testing). For some tools the correct approach would be that part is inside the source tree and part outside. - Kristian.

EXPLAIN did not mention pushdown conditions from on expressions in the 'extra' column. As a result if a query had no where conditions pushed down to a table, but had on conditions pushed to this table the 'extra' column in the EXPLAIN for the table missed 'using where'. 2. Conditions for ref access were not eliminated from on expressions though such conditions were eliminated from the where condition. Diff too large for email (23741 lines, the limit is 1000).

#At lp:maria 2784 knielsen(a)knielsen-hq.org 2009-12-12 Fix source tarball name and 99 char path limitation. Fix obsolete automake usage in AM_INIT_AUTOMAKE so we can use the option to use tar version without 99 char pathname limit. Change package name to get the source tarball to be named mariadb- not mysql-. Remove extra -MariaDB version string; we can instead change the package name and use --with-server-suffix when building packages. modified: CMakeLists.txt Makefile.am configure.in include/config-netware.h include/config-win.h scripts/Makefile.am support-files/Makefile.am win/configure.js win/make_mariadb_win_dist per-file messages: CMakeLists.txt PACKAGE macro should not be needed. Makefile.am Fix tarball path name. configure.in Fix obsolete usage of AM_INIT_AUTOMAKE. Change package name to mariadb to get proper naming of source tarball. Set option to use tar file format without 99 char lenght limit. include/config-netware.h PACKAGE macro should not be needed. include/config-win.h PACKAGE macro should not be needed. scripts/Makefile.am The path should be /mysql not /mariadb for compatibility reasons. support-files/Makefile.am The path should be /mysql not /mariadb for compatibility reasons. win/configure.js Update parsing of configure.in win/make_mariadb_win_dist Update parsing of configure.in === modified file 'CMakeLists.txt' --- a/CMakeLists.txt 2009-12-03 11:19:05 +0000 +++ b/CMakeLists.txt 2009-12-11 23:26:09 +0000 @@ -36,7 +36,6 @@ ADD_DEFINITIONS(-DDEFAULT_MYSQL_HOME="c: ADD_DEFINITIONS(-DDEFAULT_BASEDIR="c:/Program Files/MySQL/") ADD_DEFINITIONS(-DMYSQL_DATADIR="c:/Program Files/MySQL/MySQL Server ${MYSQL_BASE_VERSION}/data") ADD_DEFINITIONS(-DDEFAULT_CHARSET_HOME="c:/Program Files/MySQL/MySQL Server ${MYSQL_BASE_VERSION}/") -ADD_DEFINITIONS(-DPACKAGE=mysql) ADD_DEFINITIONS(-DSHAREDIR="share") # Set debug options === modified file 'Makefile.am' --- a/Makefile.am 2009-12-03 11:19:05 +0000 +++ b/Makefile.am 2009-12-11 23:26:09 +0000 @@ -63,7 +63,7 @@ dist-hook: # Simple target to allow scripts etc. to get the name of the source # tarball easily. show-dist-name: - @echo "$(PACKAGE)-$(VERSION)" + @echo "$(PACKAGE_TARNAME)-$(VERSION)" all-local: @ABI_CHECK@ === modified file 'configure.in' --- a/configure.in 2009-12-03 11:34:11 +0000 +++ b/configure.in 2009-12-11 23:26:09 +0000 @@ -3,8 +3,6 @@ dnl Process this file with autoconf to p AC_PREREQ(2.52)dnl Minimum Autoconf version required. -AC_INIT(sql/mysqld.cc) -AC_CANONICAL_SYSTEM # The Docs Makefile.am parses this line! # remember to also update version.c in ndb # @@ -15,7 +13,12 @@ AC_CANONICAL_SYSTEM # MySQL version number. # # Note: the following line must be parseable by win/configure.js:GetVersion() -AM_INIT_AUTOMAKE(mysql, 5.1.41-MariaDB-beta) +# and by win/make_mariadb_win_dist +AC_INIT([MariaDB], [5.1.41-beta]) +AC_CONFIG_SRCDIR(sql/mysqld.cc) +AC_CANONICAL_SYSTEM + +AM_INIT_AUTOMAKE([tar-ustar]) AM_CONFIG_HEADER([include/config.h:config.h.in]) PROTOCOL_VERSION=10 === modified file 'include/config-netware.h' --- a/include/config-netware.h 2009-07-31 19:28:15 +0000 +++ b/include/config-netware.h 2009-12-11 23:26:09 +0000 @@ -127,7 +127,6 @@ extern "C" { /* default directory information */ #define DEFAULT_MYSQL_HOME "sys:/mysql" -#define PACKAGE "mysql" #define DEFAULT_BASEDIR "sys:/" #define SHAREDIR "share/" #define DEFAULT_CHARSET_HOME "sys:/mysql/" === modified file 'include/config-win.h' --- a/include/config-win.h 2009-09-07 20:50:10 +0000 +++ b/include/config-win.h 2009-12-11 23:26:09 +0000 @@ -348,7 +348,6 @@ inline ulonglong double2ulonglong(double #ifndef CMAKE_CONFIGD #define DEFAULT_MYSQL_HOME "c:\\mysql" #define MYSQL_DATADIR "c:\\mysql\\data" -#define PACKAGE "mysql" #define DEFAULT_BASEDIR "C:\\" #define SHAREDIR "share" #define DEFAULT_CHARSET_HOME "C:/mysql/" === modified file 'scripts/Makefile.am' --- a/scripts/Makefile.am 2008-12-10 09:02:25 +0000 +++ b/scripts/Makefile.am 2009-12-11 23:26:09 +0000 @@ -96,7 +96,7 @@ CLEANFILES = @server_scripts@ \ pkgplugindir = $(pkglibdir)/plugin # Default same as 'pkgdatadir', but we can override it -pkgsuppdir = $(datadir)/@PACKAGE@ +pkgsuppdir = $(datadir)/mysql # mysqlbug should be distributed built so that people can report build # failures with it. === modified file 'support-files/Makefile.am' --- a/support-files/Makefile.am 2009-10-23 16:48:54 +0000 +++ b/support-files/Makefile.am 2009-12-11 23:26:09 +0000 @@ -38,7 +38,7 @@ EXTRA_DIST = mysql.spec.sh \ SUBDIRS = MacOSX RHEL4-SElinux # Default same as 'pkgdatadir', but we can override it -pkgsuppdir = $(datadir)/@PACKAGE@ +pkgsuppdir = $(datadir)/mysql pkgsupp_DATA = my-small.cnf \ my-medium.cnf \ === modified file 'win/configure.js' --- a/win/configure.js 2009-10-07 21:00:29 +0000 +++ b/win/configure.js 2009-12-11 23:26:09 +0000 @@ -155,8 +155,8 @@ function GetValue(str, key) function GetVersion(str) { - var key = "AM_INIT_AUTOMAKE(mysql, "; - var key2 = "AM_INIT_AUTOMAKE(mariadb, "; + var key = "AC_INIT([mysql], ["; + var key2 = "AC_INIT([mariadb], ["; var key_len = key.length; var pos = str.indexOf(key); //5.0.6-beta) if (pos == -1) @@ -166,7 +166,7 @@ function GetVersion(str) } if (pos == -1) return null; pos += key_len; - var end = str.indexOf(")", pos); + var end = str.indexOf("]", pos); if (end == -1) return null; return str.substring(pos, end); } === modified file 'win/make_mariadb_win_dist' --- a/win/make_mariadb_win_dist 2009-10-30 10:50:48 +0000 +++ b/win/make_mariadb_win_dist 2009-12-11 23:26:09 +0000 @@ -25,7 +25,7 @@ devenv.com MySQL.sln /build Debug # TODO extract version number VER=`cat configure.in | - perl -e 'while (<>) { if (/^AM_INIT_AUTOMAKE\([a-z ]*, *([0-9a-z\.-]+)/) { print "$1\n"; exit(0)} } ; exit 1'` + perl -e 'while (<>) { if (/^AC_INIT\(\[[a-z ]*\], *\[([0-9a-z\.-]+)\]/) { print "$1\n"; exit(0)} } ; exit 1'` echo Version string: $VER.

[Maria-developers] Prototype of Task Management Tool
by Adam M. Dutko 08 Dec '09

08 Dec '09

I started working on a task management tool based on the rough specification at http://askmonty.org/wiki/index.php/Tools_we_need . Account management is currently a manual process and I am currently working on adding the pieces to add products, projects and tasks. Once that is finished I will look into adding the task sharing piece and e-mail task management support. You can find the very rough proof of concept at: http://tickr.thefuturegrid.org/ and the code at: http://git.thefuturegrid.org -Adam

Re: [Maria-developers] Crash during shutdown (need help from PBXT team)
by Kristian Nielsen 07 Dec '09

[I Cc'ed Paul, let me know if there is another prefered way of communicating, like using Launchpad bugs or some mailing list] Vladimir Kolesnikov <vladimir(a)primebase.org> writes: > "Crash during shutdown (need help from PBXT team)" > > can you provide any details? Yes, of course! Just been busy with other stuff, but very happy that you mention it on your own initiative! Basically, after merging PBXT I see crashes in the main.mysqld_option_err test case. Here is an example build from Buildbot showing this: http://askmonty.org/buildbot/builders/debian5-i386-fulltest/builds/52 http://askmonty.org/buildbot/builders/debian5-i386-fulltest/builds/52/steps… The failure appears to be somewhat random, but I was able to repeat it easily enough locally using a release build. Debug build did not seem to show the problem. The issue is with the fix that Paul pushed for Bug#489088: https://bugs.launchpad.net/pbxt/+bug/489088 === modified file 'storage/pbxt/src/myxt_xt.cc' --- storage/pbxt/src/myxt_xt.cc 2009-11-27 15:37:02 +0000 +++ storage/pbxt/src/myxt_xt.cc 2009-12-01 09:50:46 +0000 @@ -3041,6 +3041,14 @@ xtPublic MX_CHARSET_INFO *myxt_getcharse return (MX_CHARSET_INFO *)&my_charset_utf8_general_ci; } +#ifdef DBUG_OFF +//typedef struct st_plugin_int *plugin_ref; +#define REF_MYSQL_PLUGIN(x) (x) +#else +//typedef struct st_plugin_int **plugin_ref; +#define REF_MYSQL_PLUGIN(x) (*(x)) +#endif + xtPublic void *myxt_create_thread() { #ifdef DRIZZLED + LEX_STRING& plugin_name = REF_MYSQL_PLUGIN(new_thd->variables.table_plugin)->name; + if ((plugin_name.length == 4) && (strncmp(plugin_name.str, "PBXT", plugin_name.length) == 0)) { + REF_MYSQL_PLUGIN(new_thd->variables.table_plugin)->ref_count--; + } new_thd->thread_stack = (char *) &new_thd; new_thd->store_globals(); lex_start(new_thd); This code crashes because new_thd->variables.table_plugin is NULL at this point in the code (or at least sometimes is).

I think you should be able to repeat the problem easily enough on Linux with a non-debug build running the test main.mysqld_option_err, but if not let me know and I will help set something up. - Kristian.

[Maria-developers] Warnings in MariaDB
by Michael Widenius 07 Dec '09

07 Dec '09

Hi! I have been removing warnings (found by buildbot) from the MariaDB 5.1 tree. (Will be pushed later today). Here is some comments, suggestions of what we still to do to make the buildbot part 'more clean: ------ We get a lot of warnings of the type: ctype-ucs2.c:206: warning: â€˜s_wcâ€™ may be used uninitialized in this function This are false warnings (The compiler is not smart enough to figure this out). The variables are also protected with the LINT_INIT() macro. Suggestion (for Kristian): - If you compile with -Wuninitialized, also use the -DFORCE_INIT_OF_VARS When compiling for valgrind, we should not use -Wuninitialized or -DFORCE_INIT_OF_VARS ------- For Percona: We get the following warnings from xtradb: ../../storage/xtradb/include/dict0dict.ic:729: warning: suggest a space before â€˜;â€™ or explicit braces around empty body in â€˜whileâ€™ statement ../../storage/xtradb/include/dict0dict.ic:788: warning: suggest a space before â€˜;â€™ or explicit braces around empty body in â€˜whileâ€™ statement ../../storage/xtradb/include/dict0dict.ic:729: warning: suggest a space before â€˜;â€™ or explicit braces around empty body in â€˜whileâ€™ statement ../../storage/xtradb/include/dict0dict.ic:788: warning: suggest a space before â€˜;â€™ or explicit braces around empty body in â€˜whileâ€™ statement ../../include/../storage/xtradb/include/dict0dict.ic:729: warning: suggest a space before â€˜;â€™ or explicit braces around empty body in â€˜whileâ€™ statement ../../include/../storage/xtradb/include/dict0dict.ic:788: warning: suggest a space before â€˜;â€™ or explicit braces around empty body in â€˜whileâ€™ statement Can you fix these ? ---------- I don't know if the following warning comes from us or from the include files: /usr/include/bits/string3.h:82: warning: call to â€˜__warn_memset_zero_lenâ€™ declared with attribute warning: memset used with constant zero length parameter; this could be due to transposed parameters Need suggestions/help to solve this one. Either we need to find the code in MariaDB that generates the warning or disable warnings in buildbot from /usr/include --------- Regards, Monty
