    * Fixed bug [MDEV-4063](https://jira.mariadb.org/browse/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](https://mariadb.com/docs/release-notes/mariadb-community-server-release-notes/old-releases/release-notes-mariadb-5-5-series).
* [Revision #3177](https://bazaar.launchpad.net/~maria-captains/maria/5.1/revision/3177)\

  * [MDEV-4029](https://jira.mariadb.org/browse/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.

  * [MDEV-3918](https://jira.mariadb.org/browse/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().
