BUGS FIXED

XtraBackup SST wouldn’t stop when MySQL was SIGKILLed. This would prevent MySQL to initiate a new transfer as port 4444 was already utilized. Bug fixed #1380697.

garbd was returning incorrect return code, ie. when garbd was already started, return code was 0. Bugs fixed #1308103 and #1422863.

wsrep_sst_xtrabackup-v2 script was causing innobackupex to print a false positive stack trace into the log. Bug fixed #1407599.

MyISAM DDL (CREATE TABLE only) isn’t replicated anymore when wsrep_replicate_myisam is OFF. Note, for older nodes in the cluster, wsrep_replicate_myisam should work since the TOI decision (for MyISAM DDL) is done on origin node. Mixing of non-MyISAM and MyISAM tables in the same DDL statement is not recommended with wsrep_replicate_myisam OFF since if any table in list is MyISAM, the whole DDL statement is not put under TOI (total order isolation). This also doesn’t work if default_storage_engine is set to MyISAM (which is not recommended for Percona XtraDB Cluster) and a table is created without the ENGINE option. Bug fixed #1402338.

Percona XtraDB Cluster now shows a warning in case additional utilities, like pv which may not affect critical path of SST, are not installed. Bug fixed #1248688.

wsrep_causal_reads variable was not honored when declared as global. Bug fixed #1361859.

garbd would not work when cluster address was specified without the port. Bug fixed #1365193.

garbd was running as root user on Debian. Bug fixed #1392388.

Errors in garbd init script stop/start functions have been fixed. Bug fixed #1367956.

If mysqld gets killed during the SST it will leave an unclean data directory behind. This would cause Percona XtraDB Cluster to fail when the server would be started next time because the data directory would be corrupted. This was fixed by resuming the startup in case wsrep-recover failed to recover due to corrupted data directory. The old behavior is still achievable through --exit-on-recover-fail command line parameter to mysqld_safe or exit-on-recover-fail under [mysqld_safe] in my.cnf. Bug fixed #1378578.

gvwstate.dat file was removed on joiner when XtraBackup SST method was used. Bug fixed #1388059.

xtrabackup-v2 SST did not clean the undo log directory. Bug fixed #1394836.

stderr of SST/Innobackupex is logged to syslog with appropriate tags if sst-syslog is in [sst] or [mysqld_safe] has syslog in my.cnf. This can be overridden by setting the sst-syslog to -1 in [sst]. Bug fixed #1399134.

clustercheck can now check if the node is PRIMARY or not, to allow for synced nodes which go out of PRIMARY not to take any writes/reads. Bug fixed #1403566.

Race condition between donor and joiner in Xtrabackup SST Configuration has been fixed. This caused XtraBackup SST to fail when joiner took longer to spawn the second listener for SST. Bug fixed #1405668.

SST will now fail early if the xtrabackup_checkpoints file is missing on the joiner side. Bug fixed #1405985.

socat utility was not properly terminated after a timeout. Bug fixed #1409710.

10 seconds timeout in Xtrabackup SST Configuration script was not enough for the joiner to delete existing files before it started the socat receiver on systems with big datadir. Bug fixed #1413879.

Conflict between enforce_storage_engine and wsrep_replicate_myisam for CREATE TABLE has been fixed. Bug fixed #1435482.

SST processes are now spawned with fork/exec instead of posix_spawn to allow for better cleanup of child processes in event of non-graceful termination (SIGKILL or a crash etc.). Bug fixed #1382797.

Variable length arrays in WSREP code were causing debug builds to fail. Bug fixed #1409042.

Signal handling in mysqld has been fixed for SST processes. Bug fixed #1399175.

Inserts to a table with autoincrement primary key could result in duplicate key error if another node joined or dropped from the cluster during the insert processing. Bug fixed #1366997.

Other bugs fixed: #1391634 and #1396757.
