From 7ff44b1a832b005264994cbdfc52f93f69b92cdc Mon Sep 17 00:00:00 2001 From: Nirbhay Choubey Date: Mon, 27 Jun 2016 18:30:07 -0400 Subject: MDEV-10161: wsrep_sync_wait not enabled when set to 1 in config file Since wsrep_sync_wait & wsrep_causal_reads variables are related, they are always kept in sync whenever one of them changes. Same is tried on server start, where wsrep_sync_wait get updated based on wsrep_causal_reads' value. But, since wsrep_causal_reads is OFF by default, wsrep_sync_wait's value gets modified and loses its WSREP_SYNC_WAIT_BEFORE_READ bit. Fixed by syncing wsrep_sync_wait & wsrep_causal_reads values individually on server start in mysqld_get_one_option() based on command line arguments used. --- mysql-test/suite/galera/t/galera_var_sync_wait.test | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'mysql-test/suite/galera/t') diff --git a/mysql-test/suite/galera/t/galera_var_sync_wait.test b/mysql-test/suite/galera/t/galera_var_sync_wait.test index 935c271a4d6..288ad62226f 100644 --- a/mysql-test/suite/galera/t/galera_var_sync_wait.test +++ b/mysql-test/suite/galera/t/galera_var_sync_wait.test @@ -5,6 +5,13 @@ --source include/galera_cluster.inc --source include/have_innodb.inc +--echo # +--echo # MDEV-10161: wsrep_sync_wait not enabled when set to 1 in config file +--echo # +# galera_2nodes.cnf sets wsrep_sync_wait to 7 +SELECT @@global.wsrep_sync_wait; +SELECT @@global.wsrep_causal_reads; + --let $wsrep_sync_wait_orig = `SELECT @@wsrep_sync_wait` --connection node_1 -- cgit v1.2.1
