Hi Alexander, Please find the rest of the review below: On Tue, Oct 20, 2009 at 10:46:08AM +0400, Alexi1952 wrote: > The diff is due to run-dependent data in log-events (e.g. in Table map table_id = 23 in my test run and = 60 in your test run). > It's me got a kink that --replace_regex will correct this in BINLOG :) Actually to correct this, mysqlbinlog should be called with > --base64-output=decode-rows options. > > Attached is corrected version of the test and result. Overall comments: --help message ============== The new syntax is not fully documented in --help --verbose output. It says: --rewrite-db=name Updates to a database with a different name than the original. and doesn't specify what is the syntax of the 'name'. I think ideally we would want to have it print --rewrite-db='from->to' but this seems to be difficult to achieve within the option parsing framework, so we could follow the approach used by the server's counterpart: --replicate-rewrite-db=name Updates to a database with a different name than the original. Example: replicate-rewrite-db=master_db_name->slave_db_name. Coding style ============ The patch violates adopted coding style in several places (We follow MySQL's coding conventions). To speed things up, I've made the fixes myself. Testing ======= Please add a checks for 1. that text form of RBR events shows rewritten database names 2. that everything works when mysqlbinlog reads events from the server. (they both seem to work, we just need test coverage). Memory errors ============= When I tried to get events from the server, using a command line like this: mysqlbinlog -uroot --verbose --base64-output=decode-rows -R -t \ --start-position=0 --host=localhost --rewrite-db='trepl->xx' \ --debug pslp2-bin.000020 I got these errors among the output: Error: Freeing wrong aligned pointer at line 1022, 'log_event.h' Error: Freeing wrong aligned pointer at line 1022, 'log_event.h' Error: Freeing wrong aligned pointer at line 1022, 'log_event.h' --(1) ... Warning: Memory that was not free'ed (456 bytes): 456 bytes at 0x86f84d8, allocated at line 201 in 'my_alloc.c' --(2) Problem (2) is repeatable with the mainline, so I've only reported it to MySQL as BUG#48281. Problem (1) is not repeatable on mainline or MariaDB. I've investigated it: === Wrong aligned pointer investigation ==== The messages are not produced when dumping local files. The message is produced from Log_event::free_temp_buf() which is called from Table_map_log_event::rewrite_db. When dumping local log, it calls dump_local_log_entries() which calls Log_event* Log_event::read_log_event(IO_CACHE* file, const Format_description_log_event *description_event) which has this code: // some events use the extra byte to null-terminate strings if (!(buf = (char*) my_malloc(data_len+1, MYF(MY_WME)))) { error = "Out of memory"; goto err; } buf[data_len] = 0; memcpy(buf, head, header_size); if (my_b_read(file, (uchar*) buf + header_size, data_len - header_size)) { error = "read error"; goto err; } if ((res= read_log_event(buf, data_len, &error, description_event))) 'buf' is what eventually will be passed to Table_map_log_event constructor. We can see that buf points to a start of chunk of my_malloc'ed memory. For the case when we read the remote log, it runs this code: static Exit_status dump_remote_log_entries(PRINT_EVENT_INFO *print_event_info, const char* logname) { ... net= &mysql->net; ... if (!(ev= Log_event::read_log_event((const char*) net->read_pos + 1 , len - 1, &error_msg, glob_description_event))) { error("Could not construct log event object: %s", error_msg); DBUG_RETURN(ERROR_STOP); } /* If reading from a remote host, ensure the temp_buf for the Log_event class is pointing to the incoming stream. */ ev->register_temp_buf((char *) net->read_pos + 1); The first argument to Log_event::read_log_event() will get passed as buffer pointer Table_map_log_event constructor. It points to NET::read_pos + 1, which is not an address we've got from my_malloc and hence it's not something we should be calling my_free() for. I've fixed thos problem too. == Comments to the code == > --- maria-5.1-wl36-orig/client/mysqlbinlog.cc 2009-10-20 00:28:26.000000000 +0400 > +++ maria-5.1-wl36/client/mysqlbinlog.cc 2009-10-20 00:25:52.000000000 +0400 ... > @@ -35,6 +35,18 @@ > #include "log_event.h" > #include "sql_common.h" > > +/* Needed for Rlp_filter */ > +struct TABLE_LIST; > + > +/* Needed for Rpl_filter */ > +CHARSET_INFO* system_charset_info= &my_charset_utf8_general_ci; > + > +#include "../sql/sql_string.h" // needed for Rpl_filter Why use server versions of sql_string when there are client/sql_string.*?

As mentioned above, I've had to actually apply some of the fixes to make sure they work. I've pushed the result into lp:~maria-captains/maria/maria-5.1-wl36 and added that tree into buildbot: http://askmonty.org/buildbot/grid?branch=maria-5.1-wl36 The remaining issues (need for testcases, help message) are obvious, so I can tell that I'll be happy with the patch if buildbot doesn't reveal any problems.

[Maria-developers] New (by Bothorsen): Provide key cache statistics (58)

----------------------------------------------------------------------- WORKLOG TASK -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- TASK...........: Provide key cache statistics CREATION DATE..: Thu, 22 Oct 2009, 12:28 SUPERVISOR.....: Bothorsen IMPLEMENTOR....: COPIES TO......: CATEGORY.......: Server-RawIdeaBin TASK ID........: 58 (http://askmonty.org/worklog/?tid=58) VERSION........: WorkLog-3.4 STATUS.........: Un-Assigned PRIORITY.......: 60 WORKED HOURS...: 0 ESTIMATE.......: 0 (hours remain) ORIG. ESTIMATE.: 0 PROGRESS NOTES: DESCRIPTION: Provide the key cache statistics available for the default cache (key blocks used, unflushed, etc.) for all named caches. Monty answers in an email: This is a much simpler task and something that is important to get done. We would have to introduce a 'show keycache statistics' command that would iterate over all keycaches and provide the statistics. The raw coding is probably 1-2 days, but on top if this we need testing, a test environment and building of biniaries for you. Henrik/Bo and Igor will come back to you with a more exact estimate.

[Maria-developers] Userstats patch applied to MariaDB 5.2
by Michael Widenius 24 Oct '09

24 Oct '09

Hi! I just finished applying / modifying / rewriting the userstats patch to MariaDB 5.2 and will commit this in a moment. As far as I know, the patch was originally made by Mark and his team, then addopted by Percona and fixed/updated by Arjen & Weldon. I send this patch in advance here, so that people that has been involved with the patch can comment on what/if still needs to be done and what would be the next steps. I will write extensive comments in the commit message, but here are the highlights: - Almost all counters are done through 'thd->status_var' (no separate counters used). This was done by creating a copy of thd->status_var at start of execution and adding the difference to user stats. The benefit of the above is: - Less code - No double counters (faster execution) - Trivial to add new counters to the statistics tables (There is a lot of counters already that can be used) - No need to reset counters - If 'userstat' is not set, very little overhead. - Changed all of MariaBB code to use handler::ha_read... instead if handler::read. This allowed me to have all counters in the ha_... wrapper The benefit are: - No need to change engine code - All engines are now measured - Formatted code to 'MariaDB' style. - Removed not called functions. - A lot of small speed improvements - Optimized hash keys to not have to do strlen(). - Store unique keys in 'keyinfo' to not have to generate keys on the fly. - Replaced 'if's with DBUG_ASSERT for things that I thought was impossible. - Change naming of some variables to be more consistent - userstat_running -> user_stat - Rows_fetched -> Rows changed - Added statistics variables (for user and client statistics) Rows_updated, Rows_deleted, Rows_inserted - Changed busy and cpu timing to double (as in Weldon's patch) - Changed position of a few columns in the information schemas to group things in a more logical way. Things that I would like to have comments one from the original authors are: - I did not remove from sql_parse.cc: if (options & REFRESH_USER_RESOURCES) reset_mqh((LEX_USER *) NULL, 0); /* purecov: inspected */ Don't understand why this should be removed. - Don't call 'set_concurrent_connections_stats()' (as per Weldon's patch) to collect information from the running threads as this leads will lead to wrong counting as all variables are not updated until the whole command is run. Here follows the patch (without the new test cases, the test cases will be in the commit). Note that I am now about to do a 'bzr gcommit' and I may fix some minor issues while I do that. You should be able to apply this directly to MariaDB 5.1 or you can pull MariaDB 5.2 later today if you want to test this. (MariaDB 5.2 is basicly MariaDB 5.1 + stable patches, so it's should be safe to use). === modified file 'configure.in' --- configure.in 2009-10-08 09:43:31 +0000 +++ configure.in 2009-10-16 13:25:43 +0000 @@ -829,7 +829,7 @@ AC_CHECK_HEADERS(fcntl.h fenv.h float.h sys/timeb.h sys/types.h sys/un.h sys/vadvise.h sys/wait.h term.h \ unistd.h utime.h sys/utime.h termio.h termios.h sched.h crypt.h alloca.h \ sys/ioctl.h malloc.h sys/malloc.h sys/ipc.h sys/shm.h linux/config.h \ - sys/prctl.h sys/resource.h sys/param.h port.h ieeefp.h \ + sys/prctl.h sys/resource.h sys/param.h port.h ieeefp.h linux/unistd.h \ execinfo.h) AC_CHECK_HEADERS([xfs/xfs.h]) @@ -2096,7 +2096,18 @@ case "$target" in # We also disable for SCO for the time being, the headers for the # thread library we use conflicts with other headers. ;;
