From 3d4a7390c1a94ef6e07b04b52ea94a95878cda1b Mon Sep 17 00:00:00 2001 From: Monty Date: Mon, 1 Feb 2016 12:45:39 +0200 Subject: MDEV-6150 Speed up connection speed by moving creation of THD to new thread Creating a CONNECT object on client connect and pass this to the working thread which creates the THD. Split LOCK_thread_count to different mutexes Added LOCK_thread_start to syncronize threads Moved most usage of LOCK_thread_count to dedicated functions Use next_thread_id() instead of thread_id++ Other things: - Thread id now starts from 1 instead of 2 - Added cast for thread_id as thread id is now of type my_thread_id - Made THD->host const (To ensure it's not changed) - Removed some DBUG_PRINT() about entering/exiting mutex as these was already logged by mutex code - Fixed that aborted_connects and connection_errors_internal are counted in all cases - Don't take locks for current_linfo when we set it (not needed as it was 0 before) --- mysys/thr_mutex.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'mysys/thr_mutex.c') diff --git a/mysys/thr_mutex.c b/mysys/thr_mutex.c index 4d6abd4ba66..f1e83db2bb6 100644 --- a/mysys/thr_mutex.c +++ b/mysys/thr_mutex.c @@ -510,7 +510,7 @@ int safe_cond_wait(pthread_cond_t *cond, safe_mutex_t *mp, const char *file, fprintf(stderr, "safe_mutex: Count was %d in thread 0x%lx when locking mutex %s " "at %s, line %d\n", - mp->count-1, my_thread_dbug_id(), mp->name, file, line); + mp->count-1, (ulong) my_thread_dbug_id(), mp->name, file, line); fflush(stderr); abort(); } @@ -564,7 +564,7 @@ int safe_cond_timedwait(pthread_cond_t *cond, safe_mutex_t *mp, fprintf(stderr, "safe_mutex: Count was %d in thread 0x%lx when locking mutex " "%s at %s, line %d (error: %d (%d))\n", - mp->count-1, my_thread_dbug_id(), mp->name, file, line, + mp->count-1, (ulong) my_thread_dbug_id(), mp->name, file, line, error, error); fflush(stderr); abort(); -- cgit v1.2.1
