    • MDEV-729 Bug #998028 - Server crashes on normal shutdown in closefrm after executing a query from MyISAM table
    • don't write a key value into the record buffer - a key length can be larger then the record length.
  • Revision #3179 Fri 2013-01-25 12:26:35 +0100
    • MDEV-759 Bug #998340 - Valgrind complains on simple selects containing expression DAY(FROM_UNIXTIME(-1))
    • check item->null_value before using the result of item->val_int()
  • Revision #3178 [merge] Mon 2013-01-21 13:48:34 -0800

    • Revision #3176.1.1 Mon 2013-01-21 11:47:45 -0800
      • Fixed bug MDEV-4063 (bug #56927). This bug could result in returning 0 for the expressions of the form <aggregate_function>(distinct field) when the system variable max_heap_table_size was set to a small enough number. It happened because the method Unique::walk() did not support the case when more than one pass was needed to merge the trees of distinct values saved in an external file.
      • Backported a fix in grant_lowercase.test from mariadb 5.5.
  • Revision #3177 Mon 2013-01-21 10:52:39 +0100
    • MDEV-4029 SELECT on information_schema using a subquery locks up the information_schema table due to incorrect mutexes handling
    • Early evaluation of subqueries in the WHERE conditions on I_S.*_STATUS tables, otherwise the subquery on this same table will try to acquire LOCK_status twice.
  • Revision #3176 [merge] Wed 2013-01-09 23:51:51 +0100
    • mysql-5.1.67 merge
  • Revision #3175 Tue 2012-12-04 17:08:02 +0100
    • proactive s/strmov/strnmov/ in sql_acl.cc and related test cases
  • Revision #3174 Fri 2012-12-21 15:17:26 +0100
    • Support VS2012. Exclude compiler-defined symbols from being exported by mysqld.exe
  • Revision #3173 Thu 2012-12-06 00:37:06 +0100
    • MDEV-3918: myisamchk bogus error for files larger than 4GB.
    • The failure is caused by failing stat() call . C Runtime function stat() uses old struct with 32bit st_size member, and since Visual Studio 2010 , it returns an error on st_size overflow (i.e on files larger than 4GB)
    • Fix replaces stat() by my_stat(), the later is backed by 64bit-able stat64().
