      MDEV-24167: Remove PFS instrumentation of buf_block_t · 1e5d989d
      Marko Mäkelä authored
      We always defined PFS_SKIP_BUFFER_MUTEX_RWLOCK, that is,
      the latches of the buffer pool blocks were never instrumented
      in PERFORMANCE_SCHEMA.
      
      For some reason, the debug_latch (which enforce proper usage of
      buffer-fixing in debug builds) was instrumented.

      MDEV-22871 fixup: Relax a debug assertion · 156cb94b
      Marko Mäkelä authored
      In commit bf3c862f we introduced
      an assertion that may dereference a null pointer.
      
      This regression was caught by running the following:
      ./mtr --parallel=auto --suite=innodb \
      --mysqld=--loose-innodb-adaptive-hash-index
      
      The adaptive hash index is disabled by default since
      commit 88cdfc5c (MDEV-20487)
      and hence the problem was not caught earlier.

      Run innodb_wl6326_big only in debug builds · 3c8ecb5b
      Marko Mäkelä authored
      The test seems to deterministically fail on RelWithDebInfo builds
      due to a timeout in wait_condition.inc.
      
      According to Matthias Leich (the original author of the test),
      the failure rate would reduce if we disabled the purge of
      transaction history by setting innodb_force_recovery=2.
      
      For now, let us run this stress test on debug builds only.

      Cleanup: Fix build problems with the Intel compiler · 8ac19be8
      Marko Mäkelä authored
      fil_space_t::flush_low(): Define and declare without inline.
      
      ut_is_2pow(): Remove UNIV_LIKELY. This is almost exclusively
      used in debug assertions. UNIV_LIKELY is not compatible with
      static_assert in some compilers.

      MDEV-24224 Gap lock on delete in 10.5 using READ COMMITTED · 33d41167
      Marko Mäkelä authored
      When MDEV-19544 (commit 1a6f4704)
      simplified the initialization of the local variable
      set_also_gap_locks, an inadvertent change was included.
      Essentially, all code branches that are executed when
      set_also_gap_locks hold must also ensure that
      trx->isolation_level > TRX_ISO_READ_COMMITTED holds.
      This was being violated in a few code paths.
      
      It turns out that there is an even simpler fix: Remove the test
      of thd_is_select() completely. In that way, the first part of
      UPDATE or DELETE should work exactly like SELECT...FOR UPDATE.
      
      thd_is_select(): Remove.
