5862a54b86 Move os_file_write() before posix_fadvise(POSIX_FADV_DONTNEED).
It is wrong to tell the OS that a block is not going to be accessed and
write to it immediately afterwards.

  Bug#53593: Add some instrumentation to improve Valgrind sensitivity

  BUILD/*: Add valgrind_configs=--with-valgrind.
  BUILD/*: Remove -USAFEMALLOC from valgrind_flags.

  configure.in: Add AC_ARG_WITH(valgrind) and HAVE_VALGRIND.

  include/my_sys.h: Define a number of MEM_ wrappers for VALGRIND_ functions.
  include/my_sys.h: Make TRASH do MEM_UNDEFINED().

  include/m_string.h: Remove unused macro bzero_if_purify(A,B).

  _mymalloc(): Declare MEM_UNDEFINED() on the allocated memory.

  _myfree(): Declare MEM_NOACCESS() on the freed memory.

  storage/innobase/include/univ.i: Enable UNIV_DEBUG_VALGRIND based on
  HAVE_VALGRIND rather than HAVE_purify.

  Possible things to do:
   * In my_global.h, remove the defined(HAVE_purify) condition
     from the _WIN32 uint3korr().
   * In my_global.h *int*korr(), use | instead of +
     in order to keep the Valgrind V bits accurate
   * Consider replacing HAVE_purify with HAVE_VALGRIND
   * Use VALGRIND_CREATE_BLOCK, VALGRIND_DISCARD in mem_root and similar places

759d5bc535 Another incarnation of the patch for Bug#30708
(make relies GNU extentions). The patch was partially
backport from 6.0.

Original comment:
bug#30708: make relies GNU extensions.  Now that we no longer use
BitKeeper we can safely remove the SCCS handling with no loss of
functionality.

2d299d84f9 Followup to Bug#51920, fix binlog.binlog_killed
This is a followup to the fix of

Bug#51920 Innodb connections in row lock wait ignore KILL until lock wait
timeout

in that fix (rb://279) the behavior was changed to honor when a trx is
interrupted during lock wait, but the returned error code was still
"lock wait timeout" when it should be "interrupted".

This change fixes the non-deterministically failing test binlog.binlog_killed,
that failed like this:

binlog.binlog_killed 'stmt'              [ fail ]
        Test ended at 2010-05-12 11:39:08

02fc9f0223 Revert the kernel mutex split phase I patch. Some artefacts have been left
in the code but they have nothing to do with the kernel mutex split code.
Some subsequent commits use the new functions. This patch has been tested
with: ./mtr --suite=innodb with UNIV_DEBUG and UNIV_SYNC_DEBUG enabled.
All tests were successful.

    Merge a patch from Facebook to fix Bug #53290

    commit e759bc64eb5c5eed4f75677ad67246797d486460
    Author: Ryan Mack
    Date:   3 days ago

        Bugfix for 53290, fast unique index creation fails on duplicate null values

        Summary:
        Bug in the fast index creation code incorrectly considers null
        values to be duplicates during block merging.  Innodb policy is that
        multiple null values are allowed in a unique index.  Null duplicates
        were correctly ignored while sorting individual blocks and with slow
        index creation.

        Test Plan:
        mtr, including new test, load dbs using deferred index creation
