Bugs fixed¶
In some cases when node is recovered variable
threads_running
would become huge. Bug fixed #1040108 (Teemu Ollakka).Variable
wsrep_defaults_file
would be set up to the value in the last configuration file read. Bug fixed by keeping the value found in the top configuration file. Bug fixed #1079892 (Alex Yurchenko).Variable
wsrep_node_name
was initialized before theglob_hostname
, which lead to empty value forwsrep_node_name
if it wasn’t set explicitly. Bug fixed #1081389 (Alex Yurchenko).Running
FLUSH TABLES WITH READ LOCK
when slave applier needed to abort transaction that is on the way caused the deadlock situation. Resolved by grabbing Global Read Lock before pausing wsrep provider. Bug fixed #1083162 (Teemu Ollakka).Percona XtraDB Cluster would crash when processing a delete for a table with foreign key constraint. Bug fixed #1078346 (Seppo Jaakola).
When variable
innodb_support_xa
was set to0
, wsrep position wasn’t stored into the InnoDB tablespace. Bug fixed #1084199 (Teemu Ollakka).Using XtraBackup for State Snapshot Transfer would fail due to
mktemp
error. Bug fixed #1080829 (Alex Yurchenko).XtraBackup donor would run XtraBackup indefinitely if the xtrabackup
--tmpdir
was ontmpfs
. Bug fixed #1086978 (Alex Yurchenko).In some cases non-uniform foreign key reference could cause a slave crash. Fixed by using primary key of the child table when appending exclusive key for cascading delete operation. Bug fixed #1089490 (Seppo Jaakola).
Percona XtraDB Cluster would crash when
binlog_format
was set toSTATEMENT
. This was fixed by introducing the warning message. Bug fixed #1088400 (Seppo Jaakola).An explicitly set
wsrep_node_incoming_address
may make “SHOW STATUS LIKE 'wsrep_incoming_addresses';
” return the address without the port number. Bug fixed #1082406 (Alex Yurchenko).Percona XtraDB Cluster would crash if the node’s own address would be specified in the
wsrep_cluster_address
variable. Bug fixed #1099413. (Alexey Yurchenko)When installing from yum repository,
Percona-XtraDB-Cluster-server
andPercona-XtraDB-Cluster-client
