From cea55f3dc68953050dacd5366a7003e2ab29cdcf Mon Sep 17 00:00:00 2001 From: Andrei Elkin Date: Thu, 4 Dec 2008 18:36:45 +0200 Subject: [PATCH] Bug #33420 Test 'rpl_packet' fails randomly with changed "Exec_Master_Log_Pos" Bug #41173 rpl_packet fails sporadically on pushbuild: query 'DROP TABLE t1' failed The both issues appeared to be a race between the SQL thread executing CREATE table t1 and the IO thread that is expected to stop at the consequent big size event. The two events need serialization which is implemented. The early bug required back-porting a part fixes for bug#38350 exclusively for 5.0 version. --- mysql-test/r/rpl_packet.result | 40 +++++----------------------------- mysql-test/t/rpl_packet.test | 22 ++++++++++++++----- 2 files changed, 21 insertions(+), 41 deletions(-) diff --git a/mysql-test/r/rpl_packet.result b/mysql-test/r/rpl_packet.result index 88c63994fff..f84ce18810e 100644 --- a/mysql-test/r/rpl_packet.result +++ b/mysql-test/r/rpl_packet.result @@ -23,39 +23,9 @@ SET @@global.max_allowed_packet=4096;
