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) --- mysql-test/t/mdev375.test | 1 + 1 file changed, 1 insertion(+) (limited to 'mysql-test/t/mdev375.test') diff --git a/mysql-test/t/mdev375.test b/mysql-test/t/mdev375.test index fe259b37808..92e403b6513 100644 --- a/mysql-test/t/mdev375.test +++ b/mysql-test/t/mdev375.test @@ -17,6 +17,7 @@ SELECT 2; --connection default SELECT 0; +show status like "Threads_connected"; SET GLOBAL log_warnings=default; SET GLOBAL max_connections=default; -- cgit v1.2.1
