- Revision #3427.1.49 Wed 2013-01-23 16:18:53 +0100
  - cleanup: remove unused init_dynamic_array and init_dynamic_array2 symbols, as only my_init_dynamic_array and my_init_dynamic_array2 are used everywhere. fix ha_cassandra to compile.
- Revision #3427.1.48 Wed 2013-01-23 16:18:09 +0100
  - cleanup: use MYF() for mysys flags
- Revision #3427.1.47 Wed 2013-01-23 16:16:14 +0100
  - MDEV-4011 Added per thread memory counting and usage Base code and idea from a patch from by plinux at Taobao.
  - The idea is that we mark all memory that are thread specific with MY_THREAD_SPECIFIC. Memory counting is done per thread in the my_malloc_size_cb_func callback function from my_malloc(). There are plenty of new asserts to ensure that for a debug server the counting is correct.
  - Information_schema.processlist gets two new columns: MEMORY_USED and EXAMINED_ROWS.
    - The later is there mainly to show how query is progressing.
  - The following changes in interfaces was needed to get this to work:
    - init_alloc_root() amd init_sql_alloc() has extra option so that one can mark memory with MY_THREAD_SPECIFIC
    - One now have to use alloc_root_set_min_malloc() to set min memory to be allocated by alloc_root()
    - my_init_dynamic_array() has extra option so that one can mark memory with MY_THREAD_SPECIFIC
    - my_net_init() has extra option so that one can mark memory with MY_THREAD_SPECIFIC
    - Added flag for hash_init() so that one can mark hash table to be thread specific.
    - Added flags to init_tree() so that one can mark tree to be thread specific.
    - Removed with_delete option to init_tree(). Now one should instead use MY_TREE_WITH_DELETE_FLAG.
    - Added flag to Warning_info::Warning_info() if the structure should be fully initialized.
    - String elements can now be marked as thread specific.
    - Internal HEAP tables are now marking it's memory as MY_THREAD_SPECIFIC.
    - Changed type of myf from int to ulong, as this is always a set of bit flags.
  - Other things:
    - Removed calls to net_end() and thd
    - cleanup() as these are now done in THD()
    - We now also show EXAMINED_ROWS in SHOW PROCESSLIST
    - Added new variable 'memory_used'
    - Fixed bug where kill_threads_for_user() was using the wrong mem_root to allocate memory.
    - Removed calls to the obsoleted function init_dynamic_array()
    - Use set_current_thd() instead of my_pthread_setspecific_ptr(THR_THD,...)

      - Cassandra SE: lazy connections
        Don't connect right away in ha_cassandra::open. If we do this, it becomes impossible to do SHOW CREATE TABLE when the server is not present.
        Note: CREATE TABLE still requires that connection is present, as it needs to check whether the specified DDL can be used with Cassandra. We could delay that check also, but then one would not be able to find out about errors in table DDL until they do a SELECT.

      - Cassandra SE:
        added option thrift_port which allows to specify which port to connect to
        not adding username/password - it turns out, there are no authentication schemes in stock cassandra distribution.
    - Revision #3413.25.30 Fri 2012-09-14 09:25:42 +0400

    - The patch lifts the limitation of the current implementation of ALTER TABLE that does not allow to build unique/primary indexes by sort for MyISAM and Aria engines.
- Revision #3427.1.29 [merge] Wed 2012-12-19 19:15:51 -0800
  - Merge mwl248->10.0-base.

      - Merge 5.5 -> mwl248
    - Revision #3413.22.10 Thu 2012-12-13 23:05:12 -0800
      - Addressed all remaining issues from the review of the patch that introduced engine independent persistent statistics. In particular: - added an enumeration type for possible values of the system variable use_stat_tables - renamed KEY::real_rec_per_key to KEY::actual_rec_per_key - optimized the collection of statistical data for any primary key defined only on one column.
    - Revision #3413.22.9 Wed 2012-12-12 23:16:54 -0800
      - Fixed bug MDEV-3891. If a query referenced some system statistical tables, but not all of them, then executing an ANALYZE command simultaneously with this query could lead to a deadlock. The fix prohibited reading statistics from system statistical tables for such queries.
      - Removed the function unlock_tables_n_open_system_tables_for_write() as not used anymore. Performed some minor refactoring of the code in sql_statistics.cc.
    - Revision #3413.22.8 Sun 2012-12-09 21:33:08 -0800
      - Addressed the following issue from the review of the patch for engine-independent statistics. If a table was created for InnoDB then the execution of the ANALYZE command over this table blocked any INSERT/DELETE/UPDATE of the table.
    - Revision #3413.22.7 Sat 2012-12-08 15:38:15 -0800
      - Addressed the following issue from the review of the patch for engine-independent statistics. When the primary key was dropped or changed statistics on secondary indexes for the prefixes that included components of the primary key was not removed from the table mysql.index_stats.
      - Also fixed: in the some cases when a column was changed statistics on the indexes that included this column was not removed from the table mysql.index_stats.
      - Also disabled the test MDEV-504 for --ps-protocol.
    - Revision #3413.22.6 Wed 2012-12-05 22:51:11 -0800
      - Addressed the following issues from the review of the patch: 1. The PERSISTENT FOR clause of the ANALYZE command overrides the setting of the system variable use_stat_tables: with this clause ANALYZE unconditionally collects persistent statistics. 2. ANALYZE collects persistent statistics only for tables of the USER category. So it never collects persistent statistics for system tables.
    - Revision #3413.22.5 Wed 2012-12-05 09:57:34 -0800
      - Adjusted results for a test. The adjustment was supposed to be done in the previous commit.
    - Revision #3413.22.4 Wed 2012-12-05 00:31:05 -0800
      - Changed the names of the system tables for statistical data: table_stat -> table_stats column_stat -> column_stats index_stat -> index_stats to be in line with the names of innodb statistical tables from mysql-5.6: innodb_table_stats and innodb_index_stats.
    - Revision #3413.22.3 [merge] Tue 2012-12-04 19:04:25 -0800
      - Merge 5.5->mwl248
    - Revision #3413.22.2 Mon 2012-11-19 13:04:37 -0800
      - Fixed bug MDEV-3866. The invalid implementation of the method Field_bit::cmp_max could trigger a valgrind complain or could lead to incorrect statistical data when collecting engine-independent statistics on BIT fields.
    - Revision #3413.22.1 [merge] Fri 2012-11-02 20:38:05 -0700
      - Merge 5.5 -> 5.5-mwl248.
      - Revision #3334.1.39 Wed 2012-09-12 15:33:03 -0700
        Made the results from the stat_tables_rbr test to be not dependent on the debug mode.
      - Revision #3334.1.38 Tue 2012-09-11 22:36:04 -0700
        Fixed bug MDEV-518. If some statistical tables are corrupted the server should use the conventional statistical data.
      - Revision #3334.1.37 Mon 2012-09-10 22:22:57 -0700
        Fixed bug MDEV-485. RBR should be turned off when statistical tables are modified in the result of the execution of a DDL statement. Revised the fix for bug MDEV-463. Ensured suppression of RBR for the modifications of the statistical tables triggered by the execution of any analyze operation.
      - Revision #3334.1.36 [merge] Sat 2012-09-08 22:36:55 -0700
        Merge 5.5 -> mwl248
      - Revision #3334.1.35 Sat 2012-09-08 20:33:03 -0700
        Part 2 of the fix for bug MDEV-504. Any Field object should use current_thd instead of table->in_use when THD is needed if table == NULL. This patch fixes the crash of test case from MDEV-504.test.
      - Revision #3334.1.34 [merge] Sat 2012-09-08 12:07:14 -0700
        Merge.
        Revision #3334.3.1 Mon 2012-09-03 22:01:52 +0400

      - Revision #3334.1.33 Sat 2012-09-08 12:04:31 -0700
        Fixed bug MDEV-504. Opening system statistical tables and reading statistical data from them for a regular table should be done after opening and locking this regular table. No test case is provided with this patch.
      - Revision #3334.1.32 Sat 2012-09-01 23:51:47 -0700
        Fixed bug MDEV-503. If a table is already in the table cache but without data from persistent statistical tables then the function open_and_process_table should not only allocate memory for this statistical data in the corresponding TABLE_SHARE object, but also should copy the references to the data into certain fields of the TABLE data structure: for each key of the table KEY::read_stats should be copied, and for each column of the table Field::read_stats should be copied.
      - Revision #3334.1.31 [merge] Wed 2012-08-29 18:50:38 -0700
        Merge 5.5->5.5-mwl248.
      - Revision #3334.1.30 Mon 2012-08-27 14:19:25 -0700
        Fixed bug MDEV-487. The function collect_statistics_for_table() when scanning a table did not take into account that the handler function ha_rnd_next could return the code HA_ERR_RECORD_DELETE that should not be considered as an indication of an error. Also fixed a potential memory leak in this function.
      - Revision #3334.1.29 Thu 2012-08-23 11:22:26 -0700
        Fixed bug MDEV-473. With the new code of mysql-5.5 for metadata locking the function unlock_tables_n_open_system_tables_for_write should not explicitly unlock tables for which external locks have been set and should not explicitly reset thd->lock to 0.
      - Revision #3334.1.28 Mon 2012-08-20 12:05:37 -0700
        Fixed bug MDEV-463. RBR should be turned off when an ANALYZE TABLE command is executed.
      - Revision #3334.1.27 Sat 2012-08-18 22:18:46 -0700
        Fixed the following problem: the syntax of the ANALYZE command did not returned an error if the list of the specified index names contained the name 'primary'.
      - Revision #3334.1.26 Sat 2012-08-18 11:49:14 -0700
        Made the process of collecting persistent statistics killable.
      - Revision #3334.1.25 Fri 2012-08-17 13:23:49 -0700
        Fixed bug MDEV-464. The value of system variable use_stat_tables was always reset to 0 ('never') by mistake at the launch of the server.
      - Revision #3334.1.24 [merge] Tue 2012-08-14 12:42:14 -0700
        Merge 5.5->5.5-mwl248

        Merge 5.5 -> 5.5-mwl248.
      - Revision #3334.1.22 Mon 2012-07-30 10:09:58 -0700
        Fixed errors in the calls of the macros my_atomic_rwlock_wrlock, my_atomic_rwlock_wrunlock.
      - Revision #3334.1.21 Fri 2012-07-27 17:33:23 -0700
        Moved the test cases for parallel execution from stat_tables.test into a separate file stat_tables_par.test because the test cases could not be run with embedded server.
      - Revision #3334.1.20 Fri 2012-07-27 12:05:23 -0700
        Added missing declaration of statistics_lock. Replaced bzero with memset. Added missing --source include/have_debug_sync.inc into stat_tables.test.
      - Revision #3334.1.19 Thu 2012-07-26 17:50:08 -0700
        Performed re-factoring and re-structuring of the code for MWL#248:
        Moved the definitions of the classes to store data from persistent statistical tables into statistics.h, leaving in other internal data structures only references to the corresponding objects.
        Defined class Column_statistics_collected derived from the class Column_statistics. This is a helper class to collect statistics on columns.
        Moved references to read statistics to TABLE SHARE, leaving the the reference to the collected statistics in TABLE.
        Added a new clone method for the class Field allowing to clone fields attached to table shares. It was was used to create fields for min/max values in the memory of the table share.
        
        Also:
        Added procedures to allocate memory for statistical data in the table share memory and in table memory.
        
        Also:
        Added a test case demonstrating how ANALYZE could work in parallel to collect statistics on different indexes of the same table.
        Added a test two demonstrate how two connections working simultaneously could allocate memory for statistical data in the table share memory.
      - Revision #3334.1.18 Tue 2012-07-10 22:12:23 -0700
        Made the output of the newly added test cases from statistics.test platform independent.
        Adjusted results of funcs_1.is_columns_mysql_embedded.
      - Revision #3334.1.17 Tue 2012-07-10 16:34:39 -0700
        Added procedures to delete records by keys from statistical tables. Now when a table is dropped the statistics on the table is removed from the statistical tables. If the table is altered in such a way that a column is dropped or the type of the column is changed then statistics on the column is removed from the table column_stat. It also triggers removal of the statistics on the indexes who use this column as its component.
        Added procedures that changes the names of the tables or columns in the statistical tables for. These procedures are used when tables/columns are renamed.
        Also partly re-factored the code that introduced the persistent statistical tables.
        Added test cases into statistics.test to cover the new code.
      - Revision #3334.1.16 [merge] Tue 2012-06-26 11:37:48 -0700
        Merge 5.5 -> 5.5-mwl248.
      - Revision #3334.1.15 Mon 2012-06-25 22:33:07 -0700
        Changed the type of all double columns in the system statistical tables mysql.column_stat, mysql.table_stat for the type DECIMAL(12,4). When cached the values from these columns are multiplied by factor 10^5 and stored as ulong numbers now.
      - Revision #3334.1.14 Sat 2012-06-02 17:19:01 -0700
        Removed the server option --stat-tables.
        Renamed the system variable optimizer_use_stat_tables to use_stat_tables.
        This variable now has only 3 possible values: 'never', 'complementary', 'preferably'.
        If the server has been launched with --use-stat-tables='complementary'|'preferably' then the statictics tables can be employed by the optimizer and by the ANALYZE command.
      - Revision #3334.1.13 Fri 2012-06-01 17:38:32 -0700
        Fixed a buildbot failure with a testcase from statistics.test that analyzes only some columns from a table.

  - MDEV-532: Fix some race conditions in test cases.
  - With MDEV-532, the binlog_checkpoint event is logged asynchronously from a binlog background thread. This causes some sporadic failures in some test cases whose output depends on order of events in binlog.
  - Fix using an include file that waits until the binlog checkpoint event has been logged before proceeding with the test case.

    - Revision #3427.7.1 Wed 2012-10-17 15:43:56 +0300
      - MDEV-452 Add full support for auto-initialized/updated timestamp and datetime
      - Generalized support for auto-updated and/or auto-initialized timestamp and datetime columns. This patch is a reimplementation of MySQL's "WL#5874: CURRENT_TIMESTAMP as DEFAULT for DATETIME columns". In order to ease future merges, this implementation reused few function and variable names from MySQL's patch, however the implementation is quite different.
      - TODO: The only unresolved problem in this patch is the semantics of LOAD DATA for TIMESTAMP and DATETIME columns in the cases when there are missing or NULL columns. I couldn't fully comprehend the logic behind MySQL's behavior and its relationship with their own documentation, so I left the results to be more consistent with all other LOAD cases.
      - The problematic test cases can be seen by running the test file function_defaults, and observing the test case differences. Those were left on purpose for discussion.
Revision #3487 Sun 2012-12-16 21:45:45 +0100
- small code cleanup taken from MySQL 5.6

Revision #3486 Sun 2012-12-16 21:11:24 +0100

MDEV-3816 init-file stops getting executed if a long enough line is encountered; on a debug version, assertion `! is_set() || can_overwrite_status' fails backport improved bootstrap error handling from 5.6

Revision #3485 Sat 2012-12-15 21:55:04 +0100
- MDEV-3834 Crossgrade from MySQL 5.6.7 to MariaDB 10.0 fails due to non-existing mysql.host table Treat the host table as optional, don't abort when it's missing
Revision #3484 Sat 2012-12-15 21:54:18 +0100
- MDEV-3837 Assertion `table->read_set == &table->def_read_set' failed on updating a performance_schema table This was failing not only for P_S, but for any engine that had HA_PRIMARY_KEY_REQUIRED_FOR_DELETE flag set (in the tree - only P_S and federated). Because of this flag, read_set and write_set were (possibly) changed on update. But later the code modified these bitmaps and restored them to the default state, losing HA_PRIMARY_KEY_REQUIRED_FOR_DELETE related changes.

Bug #11766001: 59026: ALLOW MULTIPLE --PLUGIN-LOAD OPTIONS
.
Implemented support for a new command line option :
--plugin-load-add=<comma-separated-name-equals-value-list>
This option takes the same type of arguments that --plugin-load does
and complements --plugin-load (that continues to operate as before) by
appending its argument to the list specified by --plugin-load.
So --plugin-load can be considered a composite option consisting of
resetting the plugin load list and then calling --plugin-load-add to process
the argument.
Note that the order in which you specify --plugin-load and --plugin-load-add
is important : "--plugin-load=x --plugin-load-add=y" will be equivalent to
"--plugin-load=x,y" whereas "--plugin-load-add=y --plugin-load=x" will be
equivalent to "plugin-load=x".
.
Incompatible change : the --help --verbose command will no longer print the
--plugin-load variable's values (as it doesn't have one). Otherwise both --plugin-load
and --plugin-load-add are mentioned in it.

Revision #3482 Wed 2012-12-12 19:54:04 +0200
- New results of --big test (MDEV-3862 fix).
Revision #3481 Tue 2012-11-20 15:11:22 +0200
- MDEV-3862 Lift limitation for merging VIEWS with Subqueries in SELECT list.
Revision #3480 [merge] Tue 2012-11-20 14:22:51 +0100
- Merge MariaDB 10.0-base -> 10.0
- Revision #3427.1.18 Tue 2012-11-20 14:20:26 +0100
  - MDEV-3861: Assertion in TC_LOG_MMAP.
  - Root cause was that number of entries in commit checkpoint buffer was bigger than total available entries in the mmap()'ed score file. This causes TC_LOG_MMAP to run out of entries before even the first checkpoint is started, which causes a hang.
  - Fixed by making sure we have fewer entries within one commit checkpoint than total available scorefile entries.
  - Another part of this bug was discovery of severel unrelated bugs in TC_LOG_MMAP dating back to 5.1. These were fixed in 5.1 and will be merged up (the problem this patch fixes exists only in 10.0).
Revision #3479 Thu 2012-11-15 12:54:50 +0200
- MDEV-3858 Change JOIN_TAB::records_read from ha_rows to double
- Currently JOIN_TAB::records_read is of type ha_rows. This is an integer type, which prevents proper selectivity and rows estimates.
