As documented in the bug report, the double checked locking pattern has inherent issues, and cannot guarantee correct initialization. This patch replaces the logic in init_available_charsets() with the use of pthread_once(3). A wrapper function, my_pthread_once(), is introduced and is used in lieu of direct calls to init_available_charsets(). Related defines MY_PTHREAD_ONCE_* are also introduced. For the Windows platform, the implementation in lp:sysbench is ported. For single-thread use, a simple define calls the function and sets the pthread_once control variable. Charset initialization is modified to use my_pthread_once(). |
