      WL#1687 - Optimize UNION DISTINCT ... UNION ALL (again). · 784c9526
      ingo@mysql.com authored
      HEAP: Copies the key count to a backup variable and sets the key count to zero.
      That way, no HEAP function will ever try to touch any index.
      Re-enabling is done by copying back the backup variable.
      To avoid memory leak at table close, disable deletes all index trees.
      Re-enabling must be done with empty indexes and data anyway. Otherwise,
      the indexes would need to be repaired, wich HEAP is not capable of.
      MyISAM: Only the key_map is cleared and set.
      Re-enabling must be done with empty indexes and data. Otherwise, repair needs
      to be done which will enable all keys persistently.
      The former implementation disabled only non-unique keys and maked this persistent.
      The new implementation additionally can disable all keys, but only without
      making this persistent. Re-enabling all keys can be done without repair,
      if data file and indexes are empty.

      CLIENT_MULTI_QUERIES -> CLIENT_MULTI_STATEMENTS · cab1dc62
      monty@mashka.mysql.fi authored
      New multi-key-cache handling. This was needed becasue the old one didn't work reliable with MERGE tables.
      ALTER TABLE table_name ... CHARACTER SET  ... now changes all char/varchar/text columns to the given character set
      (One must use ALTER TABLE ... DEFAULT CHARACTER SET ... to change the default character set)
      Fixed that have_compress is detected properly (fixes problems with func_compress.test on platforms without zlib)
      New syntax for CACHE INDEX ('keys' is optional if no index name is given and one mentions the key cache name only ones)
      Removed compiler warnings
      Added mysql_set_server_option() to allow clients like PHP to easaily set/reset the multi-statement flag.

      Proposed bugfix for #712 · 9b4ebf3d
      hf@deer.(none) authored
      Monty revoked any locks for temporary tables in
      ha_myisam::external_lock()
      But further code bans using write cache on nonlocked tables
      this makes operations much slower

      New SET syntax & system variables. · dddc20d9
      monty@mashka.mysql.fi authored
      Made a some new buffers thread specific and changeable.
      Resize of key_buffer.
      AUTO_COMMIT -> AUTOCOMMIT
      Fixed mutex bug in DROP DATABASE
      Fixed bug when using auto_increment as second part of a key where first part could include NULL.
      Split handler->extra() to extra() and extra_opt() to be able to support thread specific buffers.
      Don't write message to error log when slave reconnects becasue of timeout.
      Fixed possible update problem when using DELETE/UPDATE on small tables
      (In some cases we used index even if table scanning would be better)
      A lot of minior code cleanups
