This is a Monthly Rapid Update release of the MySQL Enterprise Server 5.0.
Bugs fixed:
-
Important Change: Security Fix: Additional corrections were made for the symlink-related privilege problem originally addressed in MySQL 5.0.60. The original fix did not correctly handle the data directory path name if it contained symlinked directories in its path, and the check was made only at table-creation time, not at table-opening time later. (Bug#32167, CVE-2008-2079)
See also Bug#39277.
-
Incompatible Change: There were some problems using
DllMain()hook functions on Windows that automatically do global and per-thread initialization forlibmysqld.dll:Per-thread initialization: MySQL internally counts the number of active threads, which causes a delay in
my_end()if not all threads have exited. But there are threads that can be started either by Windows internally (often in TCP/IP scenarios) or by users. Those threads do not necessarily uselibmysql.dllfunctionality but still contribute to the open-thread count. (One symptom is a five-second delay in times for PHP scripts to finish.)Process-initialization:
my_init()callsWSAStartupthat itself loads DLLs and can lead to a deadlock in the Windows loader.
To correct these problems, DLL initialization code now is not invoked from
libmysql.dllby default. To obtain the previous behavior (DLL initialization code will be called), set theLIBMYSQL_DLLINITenvironment variable to any value. This variable exists only to prevent breakage of existing Windows-only applications that do not callmysql_thread_init()and work okay today. Use ofLIBMYSQL_DLLINITis discouraged and is removed in MySQL 6.0. (Bug#37226, Bug#33031)
