Percona is glad to announce the release ofPercona XtraDB Cluster5.5.37-25.10 on May 8, 2014. Binaries are available from thedownloads areaor from oursoftware repositories.

Based onPercona Server 5.5.37-35.0including all the bug fixes in it, Galera Replicator 2.10 (including fixes in2.9and2.10milestones) and on wsrep API 25.10 (including fixes in 25.10),Percona XtraDB Cluster5.5.37-25.10is now the current stable release. All of Percona‘s software is open-source and free.

New Features:

Percona XtraDB Clusternow supports stream compression/decompression with new xtrabackup-sstcompressor/decompressoroptions.

Garbdinit script and configuration files have been packaged forCentOSandDebian, in addition, inDebiangarbdis packaged separately inpercona-xtradb-cluster-garbd-2.xpackage.

New meta packages are now available in order to make thePercona XtraDB Clusterinstallationeasier.

Debian/Ubuntudebug packages are now available for Galera and garbd.

New SST options have been implemented:inno-backup-opts, inno-apply-opts, inno-move-optswhich pass options to backup, apply and move stages ofinnobackupex.

Initial configurable timeout, of 100 seconds, to receive a first packet via SST has been implemented, so that if donor dies somewhere in between, joiner doesn’t hang. Timeout can be configured with thesst-initial-timeoutvariable.

The joiner would wait and not fall back to choosing other potential donor nodes (not listed inwsrep_sst_donor) by their state. This happened even when comma was added at the end. This fixes it for that particular case.

Support for Query Cache has been implemented.

Percona XtraDB Cluster packages are now available for Ubuntu 14.04.

Bugs Fixed:

To avoid disabling Parallel Apply in case ofSAVEPOINTorROLLBACK TO SAVEPOINTthewsrep_cert_deps_distancewas set to1.0at all times. Bug fixed#1277703.

First connection would hang after changing thewsrep_cluster_addressvariable. Bug fixed#1022250.

Whengmcast.listen_addrvariable was set manually it did not allow node’s own address ingcommaddress list. Bug fixed#1099478.

wsrep_sst_rsyncwould silently fail on joiner whenrsyncserver port was already taken. Bug fixed#1099783.

Server would segfault onINSERT DELAYEDwithwsrep_replicate_myisamset todue to unchecked dereference ofNULLpointer. Bug fixed#1165958.

Whengrastate.datfile was not getting zeroed appropriately it would lead to RBR error during the IST. Bug fixed#1180791.

Due to theProvides:line inPercona XtraDB Cluster(which providesPercona-Server-server), the commandyum install Percona-Server-serverwould installPercona XtraDB Clusterinstead of the expectedPercona Server. Bug fixed#1201499.

Replication of partition tables without binlogging enabled failed, partition truncation didn’t work because of lack of TO isolation there. Bug fixed#1219605.

Exception during group merge after partitioning event has been fixed. Bug fixed#1232747.

Default value forbinlog_formatis nowROW. This is done so thatPercona XtraDB Clusteris not started with wrong defaults leading to non-deterministic outcomes like crash. Bug fixed#1243228.

CREATE TABLE AS SELECTwas not replicated, if the select result set was empty. Bug fixed#1246921.

INSERTwould return deadlock instead of duplicate key on secondary unique key collision. Bug fixed#1255147.

Joiner node would not initialize storage engines ifrsyncwas used for SST and the first view was non-primary. Bug fixed#1257341.

Table level lock conflict resolving was releasing the wrong lock. Bug fixed#1257678.

Resolved the perl dependencies needed forPercona XtraDB Cluster5.5. Bug fixed#1258563.

Obsolete dependencies have been removed fromPercona XtraDB Cluster. Bug fixed#1259256.

GCache file allocation could fail if file size was a multiple of page size. Bug fixed#1259952.

Percona XtraDB Clusterdidn’t validate the parameters ofwsrep_provider_optionswhen starting it up. Bug fixed#1260193.

Runtime checks have been added for dynamic variables which are Galera incompatible. Bug fixed#1262188.

Node would get stuck and required restart if DDL was performed afterFLUSH TABLES WITH READ LOCK. Bug fixed#1265656.

xtrabackup-v2is now used as default SST method inwsrep_sst_method. Bug fixed#1268837.

FLUSH TABLES WITH READ LOCKbehavior on the same connection was changed to conform toMySQLbehavior. Bug fixed#1269085.

Read-only detection has been added inclustercheck, which can be helpful during major upgrades (this is used byxinetdforHAProxyetc.) Bug fixed#1269469.

Binary log directory is now being cleanup as part of the XtraBackup SST. Bug fixed#1273368.

Deadlock would happen whenNULLunique key was inserted. Workaround has been implemented to supportNULLkeys, by using themd5sum of full row as key value. Bug fixed#1276424.
