* Extended debug_sync_control life timeSergey Vojtovich2020-03-131-1/+5
| | | | | | | | It now lives from THD constructor to THD destructor. Reset before THD is released to a cache. Change user doesn't reset debug_sync_control anymore. Needed to be able to make use of DEBUG_SYNC() at later stages like ha_close_connection().

* Bug #51648 DBUG_SYNC_POINT is not defined on all platforms and mtr cant ↵Andrei Elkin2010-03-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pre-check that DBUG_SYNC_POINT has at least one strong limitation that it's not defined on all platforms. It has issues cooperating with @@debug. All in all its functionality is superseded by DEBUG_SYNC facility and there is no reason to maintain the old less flexible one. Fixed with adding debug_sync_set_action() function as a facility to set up a sync-action in the server sources code and re-writing existing simulations (found 3) to use it. Couple of tests have been reworked as well. The patch offers a pattern for setting sync-points in replication threads where the standard DEBUG_SYNC does not suffice to reach goals. mysql-test/extra/rpl_tests/rpl_get_master_version_and_clock.test: rewriting the test from GET_LOCK()-based to DEBUG_SYNC-based; a pattern of usage DEBUG_SYNC for replication testing is provided. mysql-test/suite/rpl/r/rpl_get_master_version_and_clock.result: results are changed. mysql-test/suite/rpl/t/rpl_get_master_version_and_clock.test: rewriting the test from GET_LOCK()-based to DEBUG_SYNC-based; limiting the test to run only with MIXED binlog-format as the test last some 10 secs sensitively contributing to the total of tests run. mysql-test/suite/rpl/t/rpl_show_slave_running.test: rewriting the test from GET_LOCK()-based to DEBUG_SYNC-based. sql/debug_sync.cc: adding debug_sync_set_action() function as a facility to set up a sync-action in the server sources code. sql/debug_sync.h: externalizing debug_sync_set_action(). sql/item_func.cc: purging sources from DBUG_SYNC_POINT. sql/mysql_priv.h: purging sources from DBUG_SYNC_POINT. sql/slave.cc: rewriting failure simulations to base on DEBUG_SYNC rather than GET_LOCK()-based DBUG_SYNC_POINT. sql/sql_repl.cc: removing an orphan failure simulation line because no counterpart in tests existing.
* WL#4259 - Debug Sync FacilityIngo Struewing2009-09-291-0/+60
Backport from 6.0 to 5.1. Only those sync points are included, which are used in debug_sync.test. The Debug Sync Facility allows to place synchronization points in the code: open_tables(...) DEBUG_SYNC(thd, "after_open_tables"); lock_tables(...) When activated, a sync point can - Send a signal and/or - Wait for a signal Nomenclature: - signal: A value of a global variable that persists until overwritten by a new signal. The global variable can also be seen as a "signal post" or "flag mast". Then the signal is what is attached to the "signal post" or "flag mast". - send a signal: Assign the value (the signal) to the global variable ("set a flag") and broadcast a global condition to wake those waiting for a signal. - wait for a signal: Loop over waiting for the global condition until the global value matches the wait-for signal.
