See the MariaDB 5.1.41 Release Notes for the highlights of this release.

MariaDB-5.1.41 RC is based on MySQL-5.1.41, and in addition to the changes listed in the 5.1.39 and 5.1.38 changelogs it includes these additional changes and bug fixes:

• Includes MySQL 5.1.41
• Includes XtraDB 1.0.4-8
• Includes PBXT 1.0.09f RC3
• Includes FederatedX
• Fixed typos of --engine help text.
• Added page fault counters for SHOW PROFILE on Windows.
• Fixed bug where one connection didn't see newly committed data from another connection.
• Safety change to ensure read/black trees (used with heap tables) works on 64 bit setups where ulong <> size_t
• Don't retry test cases by default
• Fixed bug where we could (under unlikely error conditions) access not initialized variable
• Added error handling for my_seek() & my_tell() failures
• Fixed Bug #485443 --with-fast-mutexes and without safe mutexes (debug build) maria do not builds
• Added 'mariadb_SERVER' as extra config group for MariaDB embedded server
• Apply the strict aliasing patch from http://lists.mysql.com/commits/89843
• Remove compiler warnings (Including some warnings from -Wstrict-aliasing)
• Don't use static link by default (in compile-pentium) as some new systems don't have all static libraries available
• Change type for functions in plugin.h:str_mysql_ftparser_param() to const unsigned char and string lengths to size_t.
  • One effect of the above change is that one needs to include mysql_global.h or define size_t before including plugin.h
  • This fixes a case where mysql_client_test failed with newer gcc that enables strict-aliasing by default
• Added protection around usage of thd->mysys_var (May be changed to 0 by scheduler)
• Fix for MySQL Bug #48357 SHOW BINLOG EVENTS: Wrong offset or I/O error
• Removed some not needed casts
• Change plugin.h to be 'binary compatible' with old versions
• Added mysql_ft_size_t typedef to plugin.h to make it trivial to change string lengths to size_t on next ABI change
• Protect stack->keywords with THR_LOCK_dbug
  • This solves a core dump in MariaDB when one sets the GLOBAL.DEBUG variable in mysql-test-run when other threads are checking the keyword list
• Fixed MySQL Bug #49474 Replication from 4.0 to 5.1 broken
• Changed -1 row number in some warnings to 0 (-1 doesn't make sense as a row number and when doing insert / load data, first row is 1, so 0 is free to use)
• Fixed MySQL Bug #47017 rpl_timezone fails on PB-2 with mismatch error
• Fixed coredump in sql_plugin.cc:intern_plugin_lock() on mysqld start with PBXT
• Ensure that mysql_get_server_version() also works if there is a non numerical prefix before the version number
• Applied patch from Alexander Barkov to fix some problems with Croatian character set and LIKE queries
• Fix for PBXT running inside embedded server (Bug #439889). Also some small fixes to make the PBXT testsuite work in --embedded.
• Add DB_TYPE_AUTOASSIGN as a better name for DB_TYPE_UNKNOWN, which is what plugins should generally use.
• Fixed bug in my_uuid() that caused failures on hpux and ia64
• Fixed bug in tc.log recovery code that caused crash_commit_before to sometimes crash.
• OpenSolaris 5.11-x86 now compiles (tested with 32 bit)
• Add BUILD/compile-bintar, which builds MariaDB with correct options for a binary tarball release.
• Various test suite fixes and improvements.
