This might leave dangling references to the mutex/condition in the per-thread information area. To fix the problem, we call exit_cond to properly remove references to the mutex, LOCK_log.

Doesn't appear to have direct user-facing changes -- closed without further action.
Description: In sql/log.c, member function wait_for_update_bin_log, a condition is entered with THD::enter_cond but is not exited. This might leave dangling references to the mutex/condition in the per-thread information area. How to repeat: See sql/log.c: 5283 int MYSQL_BIN_LOG::wait_for_update_bin_log(THD* thd, 5284 const struct timespec *timeout) 5285 { 5286 int ret= 0; 5287 const char* old_msg = thd->proc_info; 5288 DBUG_ENTER("wait_for_update_bin_log"); 5289 old_msg= thd->enter_cond(&update_cond, &LOCK_log, 5290 "Master has sent all binlog to slave; " 5291 "waiting for binlog to be updated"); 5292 if (!timeout) 5293 mysql_cond_wait(&update_cond, &LOCK_log); 5294 else 5295 ret= mysql_cond_timedwait(&update_cond, &LOCK_log, 5296 const_cast<struct timespec *>(timeout)); 5297 DBUG_RETURN(ret); 5298 }
