From 89685d55d7329065607df5a5f19b641e5947e22f Mon Sep 17 00:00:00 2001 From: Monty Date: Thu, 7 Apr 2016 19:51:40 +0300 Subject: Reuse THD for new user connections - To ensure that mallocs are marked for the correct THD, even if it's allocated in another thread, I added the thread_id to the THD constructor - Added st_my_thread_var to thr_lock_info_init() to avoid a call to my_thread_var - Moved things from THD::THD() to THD::init() - Moved some things to THD::cleanup() - Added THD::free_connection() and THD::reset_for_reuse() - Added THD to CONNECT::create_thd() - Added THD::thread_dbug_id and st_my_thread_var->dbug_id. These are needed to ensure that we have a constant thread_id used for debugging with a THD, even if it changes thread_id (=connection_id) - Set variables.pseudo_thread_id in constructor. Removed not needed sets. --- sql/sql_profile.h | 1 + 1 file changed, 1 insertion(+) (limited to 'sql/sql_profile.h') diff --git a/sql/sql_profile.h b/sql/sql_profile.h index 1d770ca1147..38682f3ddec 100644 --- a/sql/sql_profile.h +++ b/sql/sql_profile.h @@ -324,6 +324,7 @@ public: /* ... from INFORMATION_SCHEMA.PROFILING ... */ int fill_statistics_info(THD *thd, TABLE_LIST *tables, Item *cond); void reset(); + void restart(); }; # endif /* ENABLED_PROFILING */ -- cgit v1.2.1
