      A post-review fix for type-aware metadata locks. · a9520bcf
      Konstantin Osipov authored
      DDL no longer aborts mysql_lock_tables(), and hence
      we no longer need to support need_reopen flag of this
      call. 
      Remove the flag, and all the code in the server
      that was responsible for handling the case when
      it was set. This allowed to simplify: 
      open_and_lock_tables_derived(), the delayed thread,
      multi-update.
      
      Rename MYSQL_LOCK_IGNORE_FLUSH to MYSQL_OPEN_IGNORE_FLUSH,
      since we now only support this flag in open_table().
      
      Rename MYSQL_LOCK_PERF_SCHEMA to MYSQL_LOCK_LOG_TABLE,
      to avoid confusion.
      
      Move the wait for the global read lock for cases
      when we do updates in SELECT f1() or DO (UPDATE) to 
      open_table() from mysql_lock_tables(). When waiting
      for the read lock, we could raise need_reopen flag,
      which is no longer present in mysql_lock_tables().
      Since the block responsible for waiting for GRL
      was moved, MYSQL_LOCK_IGNORE_GLOBAL_READ_LOCK
      was renamed to MYSQL_OPEN_IGNORE_GLOBAL_READ_LOCK.

      Bug #51160 Deadlock around SET GLOBAL EVENT_SCHEDULER = ON|OFF · dd69b281
      Jon Olav Hauglid authored
      This deadlock could occour betweeen one connection executing
      SET GLOBAL EVENT_SCHEDULER= ON and another executing SET GLOBAL
      EVENT_SCHEDULER= OFF. The bug was introduced by WL#4738.
      
      The first connection would hold LOCK_event_metadata (protecting
      the global variable) while trying to lock LOCK_global_system_variables
      starting the event scheduler thread (in THD:init()).
      
      The second connection would hold LOCK_global_system_variables
      while trying to get LOCK_event_scheduler after stopping the event
      scheduler inside event_scheduler_update().
      
      This patch fixes the problem by not using LOCK_event_metadata to
      protect the event_scheduler variable. It is still protected using
      LOCK_global_system_variables. This fixes the deadlock as it removes 
      one of the two mutexes used to produce it.
      
      However, this patch opens up the possibility that the event_scheduler
      variable and the real event_scheduler state can become out of sync
      (e.g. variable = OFF, but scheduler running). But this can only
      happen under very unlikely conditions - two concurrent SET GLOBAL
      statments, with one thread interrupted at the exact wrong moment.
      This is preferable to having the possibility of a deadlock.
      
      This patch also fixes a bug where it was possible to exit create_event()
      without releasing LOCK_event_metadata if running out of memory during
      its exection.
      
      No test case added since a repeatable test case would have required
      excessive use of new sync points. Instead we rely on the fact that
      this bug was easily reproduceable using RGQ tests.

      Bug #51938 plugin_dir gets bad default value · d21fa142
      Mats Kindahl authored
      When building the script directory using a CMake-based build, both the
      variables in config.h.cmake (including PLUGINDIR) and the variables in
      CMakeList.txt (which includes pkgplugindir).
      
      However, for autotools-based builds, only pkgplugindir is substituted,
      which means that the plugin-path is not substituted.
      
      This patch solves the problem by using pkgplugindir, which works on both
      CMake-based and autotools-based builds, instead of PLUGINDIR.

      Fix for BUG#51716 and BUG#51787: test case improvements. · 9b5a6748
      Luis Soares authored
      Split rpl_row_charset into:
      
        - rpl_row_utf16.
        - rpl_row_utf32.
      
      This way these tests can run independently if server supports
      either one of the charsets but not both.
      
      Cleaned up rpl_row_utf32 which had a spurious instruction:
      -- let $reset_slave_type_conversions= 0

      Fix for BUG#51716 and BUG#51787. · 2c368f05
      Luis Soares authored
      In BUG#51787 we were using the wrong charset to print out the
      data. We were using the field charset for the string that would
      hold the information. This caused the assertion, because the
      string length was not aligned with UTF32 bytes requirements for
      storage.
      
      We fix this by using &my_charset_latin1 in the string object
      instead of the field->charset(). As a side-effect, we needed to
      extend the show_sql_type interface so that it took the field
      charset is now passed as a parameter, so that one is able to
      calculate the correct field size.
      
      In BUG#51716 we had issues with Field_string::pack and
      Field_string::unpack. When packing, the length was incorrectly
      calculated. When unpacking, the padding the string would be
      padded with the wrong bytes (a few bytes less than it should).
      
      We fix this by resorting to charset abstractions (functions) that
      calculate the correct length when packing and pad correctly the
      string when unpacking.

      A fix and a test case for Bug#51710 FLUSH TABLES <view> WITH READ · 861b86d6
      Konstantin Osipov authored
      LOCK kills the server.
      
      Prohibit FLUSH TABLES WITH READ LOCK application to views or
      temporary tables.
      Fix a subtle bug in the implementation when we actually
      did not remove table share objects from the table cache after 
      acquiring exclusive locks.

      Bug#33669: Transactional temporary tables do not work under --read-only · 30cb1779
      Davi Arnaut authored
      The problem was that in read only mode (read_only enabled),
      the server would mistakenly deny data modification attempts
      for temporary tables which belong to a transactional storage
      engine (eg. InnoDB).
      
      The solution is to allow transactional temporary tables to be
      modified under read only mode. As a whole, the read only mode
      does not apply to any kind of temporary table.
