Bug#33031 app linked to libmysql.lib crash if run as service in vista under localsystem There are some problems using DllMain hook functions on Windows that automatically do global and per-thread initialization for libmysqld.dll 1)per-thread initialization(DLL_THREAD_ATTACH) MySQL internally counts number of active threads that and causes a delay in in my_end() if not all threads are exited. But,there are threads that can be started either by Windows internally (often in TCP/IP scenarios) or by user himself - those threads are not necessarily using libmysql.dll functionality, but nonetheless the contribute to the count of open threads. 2)process-initialization (DLL_PROCESS_ATTACH) my_init() calls WSAStartup that itself loads DLLs and can lead to a deadlock in Windows loader. Fix is to remove dll initialization code from libmysql.dll in general case. I still leave an environment variable LIBMYSQL_DLLINIT, which if set to any value will cause the old behavior (DLL init hooks will be called). This env.variable exists only to prevent breakage of existing Windows-only applications that don't do mysql_thread_init() and work ok today. Use of LIBMYSQL_DLLINIT is discouraged and it will be removed in 6.0 |
