------------------------------------------------------------ revno: 2630.4.7 committer: Dmitry Lenev <dlenev@mysql.com> branch nick: mysql-6.0-3726-w timestamp: Sun 2008-05-25 11:19:02 +0400 message: WL#3726 "DDL locking for all metadata objects". Fixed silly mistake in test case which caused sporadic kill.test failures. mysql-test/t/kill.test: Fixed silly mistake in several places where I was supposed to be waiting for certain state of connection I actually forgot to invoke wait_condition.inc script altough set appropriate variable. Indeed this caused sporadical test failures.
