    - Revision #2502.567.161 Tue 2013-11-12 15:02:25 +0100
      - MDEV-5113 Wrong result (extra row) and valgrind warnings in Item_maxmin_subselect::any_value on 2nd execution of PS with SELECT subquery
      - When setting Item_func_not_all::test_sum_item or Item_func_not_all::test_sub_item, reset the other one to NULL - they can never be set both. When a PS is reexecuted, different executions might be optimized differently and a wrong test_su*_item might stay set from the previous execution.
  - Revision #3413.21.419 [merge] Wed 2013-11-13 08:29:12 +0400
    - Merge

      - MDEV-5257: MIN/MAX Optimization (Select tables optimized away) does not work for DateTime - MIN/MAX optimizer does a check whether a "field CMP const" comparison uses a constant that's longer than the field it is compared to. Make this check only for string columns, also compare character lengths, not byte lengths.

    - MDEV-5056: Wrong result (extra rows) with materialization+semijoin, IN subqueries Apply fix suggested by Igor: - When eliminate_item_equal() generates pair-wise equalities from a multi-equality, do generate a "bridge" equality between the first field inside SJM nest and the field that's first in the overall multi-equality.
  - Revision #3413.21.417 Mon 2013-11-11 22:53:40 +0100
    - MDEV-4723 "State" column of SHOW PROCESSLIST returns wrong values (non-ascii chars) for some states
    - allocate thd_proc_info string in thd memroot, not on the stack, so that it won't be overwritten while another thread might be printing it
  - Revision #3413.21.416 Mon 2013-11-11 17:20:18 +0100

    - by convention query execution time should be 0 if its start_time is 0 (this was lost when fixing MDEV-4578)
  - Revision #3413.21.411 Mon 2013-11-11 09:31:13 +0100

  - Revision #3413.21.398 Wed 2013-11-06 22:53:39 +0400
    - MDEV-5205 - MariaDB does not start if more than 128 cpu's are available
    - An addition to fix for MDEV-5205, fixes server crash on shutdown.
    - Thread groups are destroyed asynchronously, that is kill server thread sends shutdown request to all thread groups without waiting for compeltion.
    - It means all_groups array must not be freed until all thread groups are down. This patch suggests that all_groups is freed when last thread group is destroyed.
    - Note 1: threadpool code doesn't surround atomic ops with atomic locks, thus no locks for shutdown_group_count. Note 2: this patch preserves old behaviour, but we may need to wait until all thread groups are down before returning from tp_end().
  - Revision #3413.21.397 Tue 2013-11-05 20:30:36 +0200
    - Added usage of handler error names to mysqltest
  - Revision #3413.21.396 Tue 2013-11-05 20:28:24 +0200
    - Fixed core dump when doing "SET GLOBAL innodb_buffer_pool_evict='uncompressed'"
  - Revision #3413.21.395 Tue 2013-11-05 09:18:59 +0400
    - MDEV-5205 - MariaDB does not start if more than 128 cpu's are available
    - - thread_pool_size command line option upper limit increased to 100 000 (same as for max_connections) - thread_pool_size system variable upper limit is maximum of 128 or the value given at command line - thread groups are now allocated dynamically
    - Different limit for command line option and system variable was done to avoid additional mutex for all_groups and threadpool_max_size.
- Revision #3427.35.200 Fri 2013-11-08 15:14:18 +0100
  - MDEV-4506: Parallel replication.
  - Delete any left-over deferred_event from rpl_group_info when deleting the parent object, to protect against memory leaks.
- Revision #3427.35.199 Fri 2013-11-08 16:20:58 +0400
  - A patch from Kristian:
  - Remove rpl_group_info from THD before freeing it, to avoid access-after-free in THD.
- Revision #3427.35.198 Fri 2013-11-08 11:41:13 +0100
  - MDEV-4506: Parallel replication
  - Tested manually that crash in the middle of writing transaction on the master does correctly cause a rollback on slave, so remove the corresponding ToDo.
- Revision #3427.35.197 Thu 2013-11-07 11:56:06 +0100
  - MDEV-4506: Parallel replication
  - Fix access of freed memory in debug builds. When deleting serial_rgi, safe_mutex was trying to access current_thd, when that thd had just been deleted (I hate all this current_thd and other magic thread local storage crap used all over the code). Now delete the serial_rgi before the thd.
Revision #3898 [merge] Mon 2013-11-11 22:46:14 +0400
- Merge 10.0-monty -> 10.0
- Revision #3885.2.2 Mon 2013-11-11 16:21:31 +0400
  - MDEV-5241: Collation incompatibilities with MySQL-5.6 A clean-up: removing the code catching collation incompatibilities from handler::check_collation_compatibility(), as the collation IDs are already replaced at this point by TABLE_SHARE::init_from_binary_frm_image.
- Revision #3885.2.1 Sat 2013-11-09 00:20:07 +0200
  - MDEV-5241: Collation incompatibilities with MySQL-5.6 - Character set code & tests from Alexander Barkov - Integration with ALTER TABLE, REPAIR and open_table from Monty
  - The problem was that MySQL 5.6 added some croatian and vitanamese character set collations that are incompatible with MariaDB.
  - The fix is to move the MariaDB conflicting collation numbers out of the region that MySQL is likely to use. mysql_upgrade, REPAIR TABLE or ALTER TABLE will fix the collations. If one tries to access and old incompatible table, one will get the error "Table upgrade required...." After this patch, MariaDB supports all the MySQL character set collations and the old MariaDB croatian collations, which are closer to the latest standard than the MySQL versions.
  - New character sets: ucs2_croatian_mysql561_uca_ci utf8_croatian_mysql561_uca_ci utf16_croatian_mysql561_uca_ci utf32_croatian_mysql561_uca_ci utf8mb4_croatian_mysql561_uca_ci
  - Other things: - Fixed some compiler warnings - mysql_upgrade prints information about repaired tables. - Increased version number

- MDEV-4435 Server crashes in my_strcasecmp_utf8 on ADD KEY IF NOT EXISTS with implicit name when the key exists. Use field name as a key name if the key name wasn't specified.
Revision #3895 Sun 2013-11-10 17:51:26 +0100
- MDEV-201 - Assertion `!thd->spcont' failed in net_send_error on server shutdown

- Revision #3427.35.195 Wed 2013-11-06 14:51:06 +0100
  - MDEV-4506: Parallel replication MDEV-5217: Incorrect MyISAM event execution order causing incorrect parallel replication
  - In parallel replication, if transactions A,B group-commit together on the master, we can execute them in parallel on a replication slave. But then, if transaction C follows on the master, on the slave, we need to be sure that both A and B have completed before starting on C to be sure to avoid conflicts.
  - The necessary wait is implemented such that B waits for A to commit before it commits itself (thus preserving commit order). And C waits for B to commit before it itself can start executing. This way C does not start until both A and B have completed.
  - The wait for B's commit on A happens inside the commit processing. However, in the case of MyISAM with no binlog enabled on the slave, it appears that no commit processing takes place (since MyISAM is non-transactional), and thus the wait of B for A was not done. This allowed C to start before A, which can lead to conflicts and incorrect replication.
  - Fixed by doing an extra wait for A at the end of B before signalling C.
- Revision #3427.35.194 Wed 2013-11-06 11:29:07 +0100
  - MDEV-4506: Parallel replication MDEV-5217: Unlock of de-allocated mutex
  - There was a race in the code for wait_for_commit::wakeup().
  - Since the waiter does a dirty read of the waiting_for_commit flag, it was possible for the waiter to complete and deallocate the wait_for_commit object while the waitee was still running inside wakeup(). This would cause the waitee to access invalid memory.
  - Fixed by putting an extra lock/unlock in the destructor for wait_for_commit, to ensure that waitee has finished with the object before it is deallocated.
- Revision #3427.35.193 Wed 2013-11-06 10:18:04 +0100
  - MDEV-4506: Parallel replication MDEV-5217: Incorrect event pos update leading to corruption of reading of events from relay log
  - The rli->event_relay_log_pos was sometimes undated incorrectly when using parallel replication, especially around relay log rotates. This could cause the SQL thread to seek into an invalid position in the relay log, resulting in errors about invalid events or even random corruption in some cases.
- Revision #3427.35.192 Tue 2013-11-05 14:49:57 +0100
  - MDEV-4506: Parallel replication. MDEV-5217: Last_sql_error lost in parallel replication.
  - For some reason, the query execution code in log_event.cc call rli->clear_error for each event (part of clear_all_errors()). This causes a problem in parallel replication, where the execution in one worker thread could clear the error set by another thread, causing the SQL thread to stop but leaving no error visible in SHOW SLAVE STATUS.
  - There seems to be no reason to clear the global error code in Relay_log_info for each event execution, from code review and from running the test suite. So remove this clearing of the error code to make things work also in the parallel case.
- Revision #3427.35.191 Tue 2013-11-05 12:01:26 +0100
  - MDEV-4506: Parallel replication MDEV-5217: SQL thread hangs during stop if error occurs in the middle of an event group
  - Normally, when we stop the slave SQL thread in parallel replication, we want the worker threads to continue processing events until the end of the current event group. But if we stop due to an error that prevents further events from being queued, such as an error reading the relay log, no more events can be queued for the workers, so they have to abort even if they are in the middle of an event group. There was a bug that we would deadlock, the workers waiting for more events to be queued for the event group, the SQL thread stopped and waiting for the workers to complete their current event group before exiting.
  - Fixed by now signalling from the SQL thread to all workers when it is about to exit, and cleaning up in all workers when so signalled.
  - This patch fixes one of multiple problems reported in MDEV-5217.
