# SUMMARY
#
BUG#25211: events_bugs.test fails on sapsrv1 The problem was that the events_bugs test could randomly fail due to races in the test case. The solution is to replace fixed sleeps with reliable polling of a certain state to settle. For that, a new auxiliary script include/wait_condition.inc is used, that allows waiting for a given query to return true. mysql-test/include/wait_until_rows_count.inc: Script is rewritten using new include/wait_condition.inc. mysql-test/r/events_bugs.result: Update result: add missing quotation mark. mysql-test/t/events_bugs.test: Replace --sleep with the reliable waiting for a certain state. mysql-test/include/wait_condition.inc: New BitKeeper file ``mysql-test/include/wait_condition.inc''
