    • MDEV-4040 Replace deprecated SET OPTION syntax in mysqldump

    • MDEV-3909 remote user enumeration (CVE-2012-5615)

  • Revision #3199 [merge] Mon 2013-01-21 15:23:40 -0800

    • Revision #2643.137.36 [merge] Mon 2013-01-21 13:48:34 -0800
      • Merge.
      • Revision #2643.139.1 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 #2643.137.35 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 #3198 Sat 2013-01-19 23:40:53 -0800
  • Revision #3197 Wed 2013-01-16 11:17:58 -0800
  • Revision #3196 Tue 2013-01-15 16:46:27 -0800
    • Fixed bug MDEV-3938. The original patch with the implementation of virtual columns did not support INSERT DELAYED into tables with virtual columns. This patch fixes the problem.
  • Revision #3195 [merge] Thu 2013-01-10 13:54:04 +0100
  • Revision #3194 [merge] Fri 2012-12-21 15:19:08 +0100
    • merge
    • Revision #2643.137.32 Fri 2012-12-21 15:17:26 +0100
      • Support VS2012. Exclude compiler-defined symbols from being exported by mysqld.exe
  • Revision #3193 [merge] Fri 2012-12-21 14:04:25 +0100
    • merge
    • Revision #2643.137.31 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().
  • Revision #3192 Tue 2012-12-11 09:50:48 +0100
    • one-byte overflow with old passwords
  • Revision #3191 Mon 2012-11-26 13:33:24 +0100
    • Fix broken feedback plugin after MDEV-712.
    • Link feedback plugin with yassl libraries, if with-ssl=bundled is used, since mysqld does not export SSL symbols anymore.
  • Revision #3190 Fri 2012-11-23 13:50:46 +0100
    • MDEV-712 - Bug #1024239 - Mysqlclient exports the same symbols as openssl
    • Compile yassl and taocrypt using -fvisibility=hidden, when possible. This prevent symbols from being exported.
