Howdy, Kristian. I am forwarding for your attention a patch that HEADs bb-10.5-mdev_742 branch. While it's of some size maybe you'll find some time to review changes/extension esp done to the pararellel slave. Looking forward to hear from you! Thanks. Andrei revision-id: 25fe744e5c3d2e8f7d3db7eed37d8e412837457b (mariadb-10.5.0-283-g25fe744e5c3) parent(s): 36cebe53a3645bf1e665ffdf5b552cabcc1e8e56 author: Andrei Elkin committer: Andrei Elkin timestamp: 2020-03-04 15:48:43 +0200 message: MDEV-742 XA PREPAREd transaction survive disconnect/server restart Lifted long standing limitation to the XA of rolling it back at the transaction's connection close even if the XA is prepared. Prepared XA-transaction is made to sustain connection close or server restart. The patch consists of - binary logging extension to write prepared XA part of transaction signified with its XID in a new XA_prepare_log_event. The concusion part - with Commit or Rollback decision - is logged separately as Query_log_event. That is in the binlog the XA consists of two separate group of events. That makes the whole XA possibly interweaving in binlog with other XA:s or regular transaction but with no harm to replication and data consistency. Gtid_log_event receives two more flags to identify which of the two XA phases of the transaction it represents. With either flag set also XID info is added to the event. - engines are made aware of the server policy to keep up user prepared XA:s so they (Innodb, rocksdb) don't roll them back anymore at their disconnect methods. - slave applier is refined to cope with two phase logged XA:s including parallel modes of execution. This patch does not address crash-safe logging of the new events which is being addressed by MDEV-21469, its commit is to be published shortly. There's a list of fixes to 10.5 that were required by this MDEV, incl MDEV-21856: XID::formatID is constrained to 4 bytes by requirements of cross-platform replication and Innodb legacy. MDEV-21659 XA rollback 'foreign_xid' is allowed inside active XA MDEV-21766 Forbid XID with empty 'gtrid' MDEV-21854 xa commit 'xid' one phase for already prepared transaction must always error out Many thanks to Alexey Botchkov for driving this work initially! --- mysql-test/include/kill_and_restart_mysqld.inc | 15 + mysql-test/main/flush_read_lock.result | 76 +- mysql-test/main/flush_read_lock.test | 112 +- mysql-test/main/xa.result | 61 + mysql-test/main/xa.test | 49 + mysql-test/main/xa_binlog.result | 11 +- mysql-test/main/xa_binlog.test | 2 +- mysql-test/main/xa_prepared_binlog_off-master.opt | 1 + mysql-test/main/xa_prepared_binlog_off.result | 1044 +++++++++++++++++ mysql-test/main/xa_prepared_binlog_off.test | 11 + mysql-test/main/xa_sync.result | 10 + mysql-test/main/xa_sync.test | 5 + .../include/binlog_xa_prepare_connection.inc | 31 + .../include/binlog_xa_prepare_disconnect.inc | 35 + .../include/binlog_xa_prepared_do_and_restart.inc | 323 ++++++ .../suite/binlog/r/binlog_xa_checkpoint.result | 33 + .../suite/binlog/r/binlog_xa_prepared.result | 1176 ++++++++++++++++++++ .../binlog/r/binlog_xa_prepared_disconnect.result | 1176 ++++++++++++++++++++ .../suite/binlog/t/binlog_xa_checkpoint.test | 57 + mysql-test/suite/binlog/t/binlog_xa_prepared.inc | 102 ++ .../binlog/t/binlog_xa_prepared_disconnect.test | 11 + .../suite/rpl/include/rpl_xa_mixed_engines.inc | 183 +++ .../suite/rpl/r/rpl_parallel_optimistic_xa.result | 51 + .../r/rpl_parallel_optimistic_xa_lsu_off.result | 51 + .../suite/rpl/r/rpl_parallel_xa_same_xid.result | 23 + mysql-test/suite/rpl/r/rpl_temporary_errors.result | 47 +- mysql-test/suite/rpl/r/rpl_xa.result | 48 + mysql-test/suite/rpl/r/rpl_xa_gap_lock.result | 44 + .../suite/rpl/r/rpl_xa_gtid_pos_auto_engine.result | 64 ++ .../suite/rpl/r/rpl_xa_survive_disconnect.result | 319 ++++++ .../rpl/r/rpl_xa_survive_disconnect_lsu_off.result | 319 ++++++ .../rpl_xa_survive_disconnect_mixed_engines.result | 373 +++++++ .../suite/rpl/t/rpl_parallel_optimistic_xa.test | 235 ++++ .../t/rpl_parallel_optimistic_xa_lsu_off-slave.opt | 1 + .../rpl/t/rpl_parallel_optimistic_xa_lsu_off.test | 2 + .../suite/rpl/t/rpl_parallel_xa_same_xid.test | 138 +++ mysql-test/suite/rpl/t/rpl_temporary_errors.test | 82 +- mysql-test/suite/rpl/t/rpl_xa.inc | 73 ++ mysql-test/suite/rpl/t/rpl_xa.test | 5 + mysql-test/suite/rpl/t/rpl_xa_gap_lock-slave.opt | 1 + mysql-test/suite/rpl/t/rpl_xa_gap_lock.test | 137 +++ .../suite/rpl/t/rpl_xa_gtid_pos_auto_engine.test | 29 + .../suite/rpl/t/rpl_xa_survive_disconnect.test | 294 +++++ .../t/rpl_xa_survive_disconnect_lsu_off-slave.opt | 2 + .../rpl/t/rpl_xa_survive_disconnect_lsu_off.test | 8 + .../t/rpl_xa_survive_disconnect_mixed_engines.test | 68 ++ sql/handler.cc | 11 +- sql/log.cc | 248 ++++- sql/log.h | 10 + sql/log_event.cc | 59 +- sql/log_event.h | 213 +++- sql/log_event_client.cc | 37 +- sql/log_event_server.cc | 298 +++-- sql/rpl_parallel.cc | 220 +++- sql/rpl_parallel.h | 28 +- sql/rpl_rli.cc | 14 +- sql/rpl_rli.h | 4 + sql/slave.cc | 10 +- sql/sql_repl.cc | 4 +- sql/xa.cc | 254 ++++- sql/xa.h | 22 +- storage/innobase/handler/ha_innodb.cc | 1 + storage/innobase/trx/trx0trx.cc | 19 +- storage/rocksdb/ha_rocksdb.cc | 18 +- storage/rocksdb/mysql-test/rocksdb/r/xa.result | 41 +- storage/rocksdb/mysql-test/rocksdb/t/xa.test | 43 +- .../rocksdb/mysql-test/rocksdb_rpl/r/rpl_xa.result | 50 + .../rocksdb/mysql-test/rocksdb_rpl/t/rpl_xa.inc | 70 ++ .../rocksdb/mysql-test/rocksdb_rpl/t/rpl_xa.test | 6 + .../tokudb/mysql-test/tokudb_mariadb/r/xa.result | 1 + storage/tokudb/mysql-test/tokudb_mariadb/t/xa.test | 3 + 71 files changed, 8410 insertions(+), 212 deletions(-) diff --git a/mysql-test/include/kill_and_restart_mysqld.inc b/mysql-test/include/kill_and_restart_mysqld.inc new file mode 100644 index 00000000000..b67fb7350b4 --- /dev/null +++ b/mysql-test/include/kill_and_restart_mysqld.inc @@ -0,0 +1,15 @@ +if (!$restart_parameters) +{ + let $restart_parameters = restart;

You don't check binlog events, you don't compare master and slave, you don't even run anything on the slave to check whether your staments were replicated correctly. In fact, you don't have any slave, you have not included master-slave.inc, you only have binlog, so this test should be in the binlog suite, not in the rpl suite - it's a binlog test, not replication test. And even in the binlog suite it would make sense to see what's actually in a binlog.

[Maria-developers] GSoC-2020 Query
by Krishna Maheshwari 29 Feb '20

29 Feb '20

Hello, Everyone! I am new here and in open source too. I got to know about MariaDB through GSoC. I have intermediate level of knowledge in sql and have experience working in languages such as c, c++ and java. I did go through the list of tasks mentioned in the mariaDB GSoC 2020, and I was in particularly interested in the tasks listed under MariaDB Server: Optimizer. In that 1) Add FULL OUTER JOIN to MariaDB 2) Recursive CTE support for UPDATE (and DELETE) statements. As I understand the functioning of both of these constructs to some extent, I believe that I would be able to follow the control flow. I would really love to contribute to the code base and be of help but I just don't know where to start from.

Before your patch they were basically always enabled (because of log_warnings==2). I am not sure it's a good idea to disable warnings completely in bootstrap. If fact, I don't see why bootstrap should be special, so I'd simply remove !opt_bootstrap condition completely here. But if you want to keep it you can do something like global_system_variables > opt_bootstrap it'll make bootstrap a bit quieter than normal startup. > { > vprint_msg_to_log(level, format, args); > } > diff --git a/sql/sql_plugin.cc b/sql/sql_plugin.cc > index d7d7fcca4a2..31de259a218 100644 > --- a/sql/sql_plugin.cc > +++ b/sql/sql_plugin.cc > @@ -1679,7 +1680,22 @@ int plugin_init(int *argc, char **argv, int flags) > global_system_variables.table_plugin = > intern_plugin_lock(NULL, plugin_int_to_ref(plugin_ptr)); > DBUG_SLOW_ASSERT(plugin_ptr->ref_count == 1); > + } > + /* Initialize Aria plugin so that we can load mysql.plugin */ > + plugin_ptr= plugin_find_internal(&Aria, MYSQL_STORAGE_ENGINE_PLUGIN); > + DBUG_ASSERT(plugin_ptr || !mysql_mandatory_plugins[0]); > + if (plugin_ptr) > + { > + DBUG_ASSERT(plugin_ptr->load_option == PLUGIN_FORCE); > > + if (plugin_initialize(&tmp_root, plugin_ptr, argc, argv, false)) > + { > + if (!opt_help) > + goto err_unlock; > + plugin_ptr->state= PLUGIN_IS_DISABLED; > + } > + else > + aria_loaded= 1; > } > mysql_mutex_unlock(&LOCK_plugin); I think this should be done differently. In a completely opposite way. I had unfurtunately hard-coded MyISAM here. A proper fix here could be to remove this special treatment of MyISAM instead of adding another special treatment of Aria. Then plugin_init() could work like: * run dd_frm_type() for the mysql.plugin table - like it's done now * instead of hard-coding MyISAM (and Aria), find this engine name in the plugin_array[] (note, all builtin plugins are already there) * initialize it and (if successful) load mysql.plugin table It only concerns the sql_plugin.cc part of your commit. Your aria part of the commit is still needed, because a good-behaving engine has to be read-only in --help. Regards, Sergei VP of MariaDB Server Engineering and security(a)mariadb.org

No, I don't get it. Old method meant "Check if the key is a clustered and a reference key". Just "clustered" is marked with HA_CLUSTERED_INDEX. So, 1. You've renamed the method but the name does not match the semantics. It is called is_clustering_key() but it really means "clustered AND reference key" 2. What other engine can be where the reference key isn't a primary key? Regards, Sergei VP of MariaDB Server Engineering and security(a)mariadb.org

Re: [Maria-developers] MDEV-21580: Allow packed sort keys in sort buffer, part #3

Hi Varun, Please more input below: Input on code structure: > SORT_INFO *filesort(THD *thd, TABLE *table, Filesort *filesort... > { > ... > if (!(sort_keys= filesort->make_sortorder(thd, join, first_table_bit))) > DBUG_RETURN(NULL); /* purecov: inspected */ The main effect of this function used to be to create Filesort::sortorder, and so the name 'make_sortorder' used to make sense. Now, it creates a Sort_keys object so the name is counter-intuitive. .. > uint sort_len= sortlength(thd, sort_keys, &multi_byte_charset, > &allow_packing_for_sortkeys); Another counter-intuitive name. Maybe this should be a method of sort_keys object with a different name? And maybe this call and make_sortorder should be moved together since they're logically doing the same thing? ... > Sort_keys* > Filesort::make_sortorder(THD *thd, JOIN *join, table_map first_table_bit) > { ... > if (!sortorder) > sortorder= (SORT_FIELD*) thd->alloc(sizeof(SORT_FIELD) * count); Using "if(!sortorder)" means the sort order can be already present? Is this because we're inside a subquery which we are re-executing? ... > Sort_keys* sort_keys= new Sort_keys(sort_keys_array); But then, we create sort_keys every time, and we do it on a MEM_ROOT which causes a potential O(#rows_examined) memory use. Is my logic correct? I think we should only call make_sortorder() if this hasn't already been done. Any objections to this? > > void Filesort_buffer::sort_buffer(const Sort_param *param, uint count) > { > > ... > qsort2_cmp cmp_func= param->using_packed_sortkeys() ? > get_packed_keys_compare_ptr() : > get_ptr_compare(size); > > my_qsort2(m_sort_keys, count, sizeof(uchar*), cmp_func, > param->using_packed_sortkeys() ? > (void*)param : > (void*) &size); This choose-the-comparison-function logic is duplicated in merge_buffers(). Can we have in one place? I would add appropriate members into class Sort_key (or Sort_param). > if (param->using_packed_addons() || param->using_packed_sortkeys()) > { > /* > The last record read is most likely not complete here. > We need to loop through all the records, reading the length fields, > and then "chop off" the final incomplete record. > */ Why change the identation of this block, from correct to invorrect one? Please move it back two spaces to the left. > static uint make_sortkey(Sort_param *param, uchar *to, uchar *ref_pos) > This function only seems to access Sort_param members that relate to Sort_keys. Did you consider making it accept Sort_keys as an argument? This seems like a sound idea to me: make_sortkey() is only concerned with making sort keys from original records. This is what Sort_keys class should be handling. Sort_param on the other hand covers the entire sorting process: the buffers, total # of rows, etc. Please give it a try.

I thought DISTINCT will be just CYCLE with an empty list of non-distinct columns. Or something like that.

[Maria-developers] Lag Free ALTER Table for Slave
by Sachin Setiya 27 Feb '20

27 Feb '20

Hi Everyone! This mail will describe usage and implementation of Lag Free Alter. And this will also answer the question raised by Kristian and Simon J Mudd(in 2016) Desc:- This will split Alter into 2 different commits. START ALTER and COMMIT /ROLLBACK ALTER , Start Alter will be written in binlog as soon as we get the locks for the table, alter will proceeds as usual and at the time of writing binlog if alter is successful we will write COMMIT Alter other wise ROLLBACK Alter. Usage:- Using this feature is quite simple. 1. On master you have to turn on `BINLOG_SPLIT_ALTER` dynamic variable. 2. Slave must be using parallel replication. Advance Usage:- So alter is divided like this. 1. START identifier Actual_alter_stmt 2. COMMIT/ROLLBACK identifier Actual_alter_stmt. OR 2. COMMIT/ROLLBACK identifier ALTER identifier is thread_id. Questions by Simon Mudd. >>* this behaviour should be configurable? Yes. >> - new global variable on the master to allow injection of this changed event stream? Right , `BINLOG_SPLIT_ALTER` >> - a new session variable set in the session where the command is triggered ? Right , `BINLOG_SPLIT_ALTER` >> - on slave a setting to indicate how many INPLACE ALTER TABLEs can run at once? No setting so far , but I am thinking of maximum no of CONCURRENT ALTER = slave_parallel_threads >>* how does a DBA monitor what’s going on? >> - the progress and number of active DDL statements So as we there is 2 part, So progress will go like this 1. Executing of start alter (this will take most of time) 2. Waiting for commit/rollback Signal 3. Commit/ Rollback Alter. Number of active ALTER , these will create new threads so DBA can know using this or I am thinking of adding variable in SHOW SLAVE INFO. which will show active DDL. >> - please consider adding counters/metrics for: >> * number of “asynchronous DDLs” in progress / completed successfully / failed or rolled back Okay, We can have counter for these metrics. If i get time to implement this. >> * sizes of the DDL changes made so far Not sure if we need this. >> * number of threads busy in this state (maybe can be implied from SHOW PROCESSLIST or equivalent but nicer to have an easy to query metric) Show processlist will show the busy threads.

(the statement on the master could be skipped for one of several reasons) So here are 2 options If slave is still running DBA can manually run COMMIT/ROLLBACK identifier alter_stmt/ALTER , where identifier is same as START ALTER identifier. so this will either commit or rollback alter. If slave is not running. Since slave is not running all context is lost , so this will take as much as time a normal alter. >> - I assume that users on the slave see the old structure all the time until it completes Right, we work on copy of alter for myisam and for other case innodb will take care of it. >> - would this have a storage or performance penalty on the slave if the commit/rollback DDL event never arrives? Not performance but yes storage and ram penalty. >> - can a “commit” / “rollback” be manually triggered by the DBA in such circumstances? yes. >>* what happens if the server crashes while this process (or these processes) are ongoing when the server starts up again? So if we crash in START ALTER no issue , we can run it again , since it is transactional(we are working on copy so ..) If we crash after start alter and we receive COMMIT alter then it will be treated as normal alter. ROLLBACK ALTER will be instant. If we crash in COMMIT ALTER this will be same as crash in normal ALTER table , so DBA has to deal with it. Architecture:- Lets look at sample alter perf data for innodb and myisam Myisam + 96.72% 0.00% mysqld mysqld [.] mysql_parse + 96.72% 0.00% mysqld mysqld [.] mysql_execute_command + 96.72% 0.00% mysqld mysqld [.] Sql_cmd_alter_table::execute - 96.72% 0.00% mysqld mysqld [.] mysql_alter_table - mysql_alter_table - 96.63% copy_data_between_tables + 79.64% handler::ha_write_row + 6.24% TABLE::update_default_fields + 5.71% READ_RECORD::read_record + 1.87% do_copy_null 1.05% Field::do_field_int + 0.95% _mcount InnoDB + 41.27% 0.00% mysqld mysqld [.] mysql_parse + 41.27% 0.00% mysqld mysqld [.] mysql_execute_command + 41.27% 0.00% mysqld mysqld [.] Sql_cmd_alter_table::execute - 41.27% 0.00% mysqld mysqld [.] mysql_alter_table - mysql_alter_table - 41.27% mysql_inplace_alter_table - 41.15% handler::ha_inplace_alter_table ha_innobase::inplace_alter_table - row_merge_build_indexes - 41.00% row_merge_read_clustered_index + 22.88% row_merge_insert_index_tuples + 5.89% row_build_w_add_vcol + 5.20% BtrBulk::finish + 3.20% row_merge_buf_add + 0.87% page_cur_move_to_next 0.62% rec_get_offsets_func So as we can see most of the work is done by copy_data_between_tables/ mysql_inplace_alter_table. Master Side:- There is not much change into master side. So after locking table and before executing these functions we write START _id_ alter_stmt into binlog. And at the time of write_bin_log we write COMMIT _id_ alter_stmt into binlog. So alter statement will be divided into 2 , hence 2 gtid. START_ALTER will have special flag FL_START_ALTER_E1(4), this will be used on slave side to create new worker thread for start alter processing. Slave Side:- This require parallel replication on slave side. So in do_event when we get a gtid_event with FL_START_ALTER_E1, ::choose_thread will call rpl_parallel_add_extra_worker, which will create a new worker thread and this will do start alter processing. So the gtid_log_event and next Query_log_event will be scheduled to this new thread. And this thread will be exited as soon as alter is finished. On slave side START ALTER will binlog after successfully getting MDL lock and thd lock. Untill this point we are executed as DDL(so new GCO), but after getting locks we will call finish_event_group. So that new events can proceed in parallel. Then it will continue to execute code in mysql_alter_table until we reach a non transactional part(like renaming table/dropping table in myisam) So before executing NON-Transactional part it will wait signal from other worker thread to either abort or proceed forward. We will add a entry into mi-> start_alter_list, with thread_id(of master) as a key. COMMIT/ROLLBACK Alter is treated as a normal query_log_event so it will be assigned normal worker. This command will take SQLCOM_COMMIT_PREVIOUS path in mysql_execute_command. We will simple search for thread_id into start_alter_list and change status from ::WAITING to ::COMMIT_ALTER and signal the wait condition if we dont find the thread_id we will wait on wait condition, So simple it is just consumer producer between start alter and commit/rollback. Questions by Kristian:- >Can you explain what you mean by "true LOCK=NONE"? It is not clear from your >description. I think you mean something that will allow to run an ALTER >TABLE on the slave in parallel with the same statement on the master? Yes >There will be a number of things to consider with this. Previously, all >transactions in the binlog have been atomic; this introduces related events >that can be arbitrarily separated in the binlog. >For example, suppose the slave stops in the middle between BEGIN_DDL_EVENT >and COMMIT_DDL_EVENT/ROLLBACK_DDL_EVENT. What is then the slave's binlog >position / GTID position? Now we are using 2 gtid for ALTER , So it wont be issue. >Hopefully, the exiting pool of slave worker threads (currently used for >parallel replication) can be used for this as well? Doesn't seem right to >introduce a new kind of thread pool... We are using same(global) thread pool but I am creating new threads for START ALTER. Otherwise we will have a deadlock , Suppose if we have 5 concurrent START ALTER and just 5 slave-worker-threads , all worker will be waiting for COMMIT/ROLLBACK, but we cant execute commit rollback because we dont have any free worker. There can be more case when we have concurrent DML too , so creating a new thread was the safest option. >Won't you need some mechanism to prevent following events to access the >table before ALTER TABLE in a worker thread can acquire the metadata lock? Right, So Untill Locking START ALTER is executed as DDL so no following event will be executed before locking. And one more thing regarding locks , So there will we only one thread will be doing whole work of alter, (we can just assume that there is some sleep on slave) so execution on master and slave will be equivalent. >There are some nasty issues to be aware of with potential deadlocks related >to FLUSH TABLES WITH GLOBAL READ LOCK and such, when multiple threads are >trying to coordinate waiting and locking; there were already some quite hard >issues with this for parallel replication. I have to test for it. Code branch bb-10.5-olter Jira (Mdev-11675(https://jira.mariadb.org/browse/MDEV-11675)) Regards Sachin -- Regards Sachin Setiya Software Engineer at MariaDB
