  • Revision #3477 Fri 2012-11-09 18:23:10 +0100
    • MDEV-3847 : MSI installer does not work.
    • Fix bug in bootstrapper.
    • Also, delete innodb log files cafter bootstrapping , to workaround "different log size" Innodb error during the first service start by MSI. This is a temporary measure, in the future innodb will allow handling different file size more gracefully.
  • Revision #3476 Tue 2012-11-06 22:20:13 +0100
    • MDEV-3839 : on Solaris 10, KILLing slave thread has no effect.
    • The reason for the error is missing definition for SIGNAL_WITH_IO_CLOSE on this platform which now needs to always be defined, as in 5.6
    • On Solaris10 only, this preprocessor constant was not defined, thus code that shutdowns a socket in THD::awake was not executed, and polling thread was not interrupted.
    • Fix is to always define SIGNAL_WITH_IO_CLOSE, just like MySQL5.6 does.
  • Revision #3475 Mon 2012-11-05 12:40:17 +0100
    • set username=hostname=NULL in the P_S for the aria background checkpoint thread
  • Revision #3474 Sun 2012-11-04 21:04:34 +0100

    • MDEV-3822 :10.0-serg fails on windows buildslaves
    • Fix mismerged code from 5.6 (named-pipe related). viopipe.c, which was introduced in 5.6 is now copied almost identically into 10.0
    • The unused vio::pipe_overlapped is removed.
  • Revision #3472 [merge] Sun 2012-11-04 19:32:32 +0400

AFTER FLUSH TABLES [-INT VS NULL]"
.
guilhem.bichot@oracle.com-20111209150650-tzx3ldzxe1yfwji6
Fix for LPBUG#12912171 - ASSERTION FAILED: QUICK->HEAD->READ_SET == SAVE_READ_SET
and
    • and related fixes from: BUG#1006164, MDEV-376:
      • Now, ROR-merged QUICK_RANGE_SELECT objects make no assumptions about the values of table->read_set and table->write_set.
      • Each QUICK_ROR_SELECT has (and had before) its own column bitmap, but now, all QUICK_ROR_SELECT's functions that care: reset(), init_ror_merged_scan(), and get_next() will set table->read_set when invoked and restore it back to what it was before the call before they return.
      • This allows to avoid the mess when somebody else modifies table->read_set for some reason.
  • Revision #3470 [merge] Sat 2012-11-03 12:28:51 +0100

  • Revision #3466 Tue 2012-10-30 18:15:42 +0100
    • disable x86 asm version of taocrypt arc4 code for gcc, because it assumes the function prologue that gcc does not generate.

    • Ensure semicolons are not lost when concatenating fill_help_tables to bootstrap.sql in Windows. 5.6 bootstrapper requires semicolons to separate bootstrapper commands.
  • Revision #3462 Mon 2012-10-29 16:30:06 +0100
    • P_S test failures on 32-bit platforms: always use intptr type when casting a pointer to an integer to avoid sign expansion. or, at least, cast identically in socket_summary_by_instance and socket_instances
  • Revision #3461 Mon 2012-10-29 15:38:53 +0100
    • compilation failure with libwrap

    • workaround for gcc 4.3.2 bug on lenny-x86 at -O3
    • The following piece of code in trnman.c:
      345   trn->min_read_from=  active_list_min.next->trid;
...
351   active_list_max.prev= trn->prev->next= trn;
352   trid_min_read_from= active_list_min.next->min_read_from;
    • on 345 gcc stores active_list_min.next in %ebx (and trn->min_read_from=[%ebx]->trid) and on 352 it does trid_min_read_from= [%ebx]->min_read_from; BUT active_list_min.next was changed on the line 351. gcc doesn't notice it and continues to use the cached value.

      • Revision #3427.5.1 [merge] Thu 2012-10-04 01:37:58 +0300
        • Implementation of Multi-source replication (MDEV-253)
        • Documentation of the feature can be found at: http://kb.askmonty.org/en/multi-source-replication/
        • This code is based on code from Taobao, developed by Plinux
        • Other things:
          • Added new commands: START ALL SLAVES, STOP ALL SLAVES and SHOW FULL SLAVE STATUS
          • Almost all usage of 'active_mi' is deleted.
          • Added parameter to reset_logs() so that one can specify if new logs should be created.
          • Check wildcard match as early as possible for SHOW STATUS. This makes SHOW STATUS like 'xxx' a lot faster and use less mutex
          • Made max_relay_log_size depending on master connection.
          • Added sys_vars.default_master_connection_basic to fix a failure in sys_vars.all_vars, modified sql_slave_skip_counter_basic to allow session-level settings
          • Added commands to mysqladmin: start-all-slaves & stop-all-slaves
          • Removed logging of "next log '%s' is currently active | not active"
          • Fixed bug in my_vsnprintf() when using positional parameters with length
          • Added fn_ext2(), which returns pointer to last '.' in file name
          • max_relay_log_size now acts as a normal slave specific variable
          • Don't store replication position if innobase_overwrite_relay_log_info is not set
          • max_relay_log_size copies it's values from max_binlog_size at startup
          • Revision #3427.4.6 Wed 2012-10-03 01:44:54 +0300
            • Changed SHOW_FUNC variabels that don't return SHOW_ARRAY to SHOW_SIMPLE_FUNC.
            • This allows us to avoid calculating variables (including those involving mutex) that doesn't match the given wildcard in SHOW STATUS LIKE '...'
            • Removed all references to active_mi that could cause problems for multi-source replication.
            • Added START|STOP ALL SLAVES
            • Added SHOW ALL SLAVES STATUS
          • Revision #3427.4.5 Mon 2012-10-01 02:30:44 +0300
            • Made max_relay_log_size depending on master connection.
            • Changed names of multi-source log files so that original suffixes are kept.
          • Revision #3427.4.4 Fri 2012-09-28 21:22:24 +0300
            • Fixed issues found by QA (Elena)
            • Added parameter to reset_logs() so that one can specify if new logs should be created.
          • Revision #3427.4.3 Fri 2012-09-28 09:28:40 +0400
            • Tests for Multi-source replication (MDEV-253)
          • Revision #3427.4.2 Fri 2012-09-28 03:45:05 +0300
            • Added multi-source support to show relaylog events
          • Revision #3427.4.1 Fri 2012-09-28 02:06:56 +0300
    • Revision #3427.1.9 [merge] Thu 2012-10-04 01:03:55 +0300
      • Automatic merge
    • Revision #3427.1.8 [merge] Sat 2012-09-22 17:11:40 +0300
    • Revision #3427.1.7 Thu 2012-09-13 14:31:29 +0200
      • MDEV-232: Remove one fsync() from commit phase.
      • Introduce a new storage engine API method commit_checkpoint_request().
        • This is used to replace the fsync() at the end of every storage engine commit with a single fsync() when a binlog is rotated.
      • Binlog rotation is now done during group commit instead of being delayed until unlog(), removing some server stall and avoiding an expensive lock/unlock of LOCK_log inside unlog().
    • Revision #3427.1.6 Fri 2012-06-22 11:46:28 +0200
      • MDEV-181: XID crash recovery across binlog boundaries
      • Keep track of how many pending XIDs (transactions that are prepared in storage engine and written into binlog, but not yet durably committed on disk in the engine) there are in each binlog.
      • When the count of one binlog drops to zero, write a new binlog checkpoint event, telling which is the oldest binlog with pending XIDs.
      • When doing XA recovery after a crash, check the last binlog checkpoint event, and scan all binlog files from that point onwards for XIDs that must be committed if found in prepared state inside engine.
      • Remove the code in binlog rotation that waits for all prepared XIDs to be committed before writing a new binlog file (this is no longer necessary when recovery can scan multiple binlog files).
    • Revision #3427.1.5 Fri 2012-06-22 11:40:40 +0200
      • MDEV-225: Replace with dummy events an event that is not understood by a slave to which it should be sent
      • Add function to replace arbitrary event with dummy event.
      • Add code which uses this to fix the bug that enabling row_annotate events on the master breaks slaves which do not request such events.
      • Add that slaves set a variable @mariadb_slave_capability to inform the master in a robust way about which events it can, and cannot, handle.
      • Add tests.
    • Revision #3427.1.4 Sat 2012-09-08 12:15:55 +0200
      • MDEV-457 Inconsistent data truncation on datetime values with fractional seconds represented as strings with no delimiters
      • New implementation for str_to_datetime. Fix MDEV-457 and related issues.
    • Revision #3427.1.3 Tue 2012-09-04 19:26:30 +0300
      • Switch automaticly to statement based replication for statements that can't generate row based events. This is needed to avoid getting updates to system, statistics and admin tables logged to binary log.
        • Removed special code used to temporarily change to statement based replication.
        • Changed to a faster and smaller interface for temporarily switching to statement based replication.
    • Revision #3427.1.2 [merge] Sat 2012-09-01 19:41:38 -0700
      • Merge MDEV-415 -> 10.0-base.
      • Revision #3427.2.1 Sat 2012-09-01 14:21:59 -0700
        • MDEV-415: Back-port of the WL task #1393 from the mysql-5.6 code line.
        • The task adds a more efficient handling of the queries with ORDER BY order LIMIT n, such that n is small enough and no indexes are used for order.
    • Revision #3427.1.1 [merge] Sat 2012-09-01 00:54:54 +0300
      • Automatic merge with 5.5
  • Revision #3448 Fri 2012-10-12 11:00:01 +0200
    • MDEV-3802: Millisecond timeout support in non-blocking client library + fix incorrect blocking.
    • After the merge of VIO stuff from MySQL 5.6, there were some bugs left in the non-blocking client library:
      • vio_io_wait() was introduced without any support for non-blocking operation, so async queries could turn into sync.
      • Timeouts were changed to milliseconds, but this was not reflected in the non-blocking API, also semantics was changed so signed -1 was used for "no timeout" rather than unsigned 0.
    • Fix by implementing and using my_io_wait_async() in the non-blocking case. And by introducing a new mysql_get_timeout_value_ms() API function that provides the timeout with millisecond granularity. The old mysql_get_timeout_value() is kept and fixed to work correctly, converting the timeout to whole seconds.
