# # BUG#45214 # The common part of the "rpl_get_master_version_and_clock" test. # Restart slave under network disconnection between slave and master # following the steps: # 0 - Set DEBUG_SYNC_ACTION to wait # before call mysql_real_query(...) function in get_master_version_and_clock(...) # function and hang here # 1 - activate a sync-point through the $dbug_sync_point argument of the test # 2 - shutdown master server for simulating network disconnection # 3 - signal to the IO thread through $debug_sync_action to unhold from the sync-point # 4 - check if the slave I/O thread tries to reconnect to master. # # Note: make sure to initialize the $debug_sync_action and $dbug_sync_point # before calling the test script. # # Pattern of usage: # # The caller test supplies the DBUG_EXECUTE_IF name # # let $dbug_sync_point = 'dbug_execute_if_name'; # # as well as the action list for DEBUG_SYNC # # let $debug_sync_action= 'now signal signal_name'; # # The $dbug_sync_point becomes the value of @@global.debug generating # a newly started IO-slave thread's session value. # Notice incremental operations to add and remove dbug_execute_if_name # from the global variable allows propagation more dbug arguments # out of mtr. # The action list is to fire at proper time according to test logics # (see pp 0-4 above). # connection slave; if (!$debug_sync_action) { --die Cannot continue.
