in load_defaults() load_defaults(), my_search_option_files() and my_print_default_files() utilized a global variable containing a pointer to thread local memory. This could lead to race conditions when those functions were called with high concurrency. Fixed by changing the interface of the said functions to avoid the necessity for using a global variable. Since we cannot change load_defaults() prototype for API compatibility reasons, it was renamed my_load_defaults(). Now load_defaults() is a thread-unsafe wrapper around a thread-safe version, my_load_defaults(). mysys/default.c: 1. Added a thread-safe version of load_defaults(), changed load_defaults() with the old interface to be a thread-unsafe wrapper around the thread-safe version. 2. Always use a private MEM_ROOT in my_print_default_files, don't use a global variable. sql-common/client.c: Use a thread-safe version of load_defaults(). |
