Percona is glad to announce the release of Percona Server 5.5.34-32.0 on October 28th, 2013. Downloads are available here and from the Percona Software Repositories.
Based on MySQL 5.5.34, including all the bug fixes in it, Percona Server 5.5.34-32.0 is now the current stable release in the 5.5 series. All of Percona‘s software is open-source and free, all the details of the release can be found in the 5.5.34-32.0 milestone at Launchpad.
New Features¶
Percona Server has extended the
SELECT INTO ... OUTFILE
andSELECT INTO DUMPFILE
to add the support for UNIX sockets and named pipes.Percona Server now provides additional information in the slow query log when
log_slow_rate_limit
variable is enabled.A new variable
slow_query_log_always_write_time
has been introduced. It can be used to specify an additional execution time threshold for the slow query log, that, when exceeded, will cause a query to be logged unconditionally, that is,log_slow_rate_limit
will not apply to it.Utility user feature has been extended by adding a new
utility_user_privileges
that allows a comma separated value list of extra access privileges that can be granted to the utility user.
Bugs Fixed¶
Due to an incompatible upstream change that went in unnoticed, the log tracker thread would attempt to replay any file operations it encountered. In most cases this were a no-op, but there were race conditions for certain
DDL
operations that would have resulted in server crash. Bug fixed #1217002.
apt-get upgrade
of Percona Server would fail in post-installation step if server failed to start. Bug fixed #1002500.Fixed the
libssl.so.6
dependency issues in binary tarballs releases. Bug fixed #1172916.Error in
install_layout.cmake
could cause that some library files, during the build, end up in different directories on x86_64 environment. Bug fixed #1174300.Percona Server could crash while accessing
BLOB
orTEXT
columns in InnoDB tables if Support for Fake Changes was enabled. Bug fixed #1188168.Memory leak was introduced by the fix for bug #1132194. Bug fixed #1204873.
The unnecessary overhead from persistent InnoDB adaptive hash index latching has been removed, potentially improving stability of the Multiple Adaptive Hash Search Partitions feature as well. Upstream bug fixed #70216, bug fixed #1218347.
Fixed the incorrect dependency with
libmysqlclient18-dev
from Percona Server5.5.33-31.1
. Bug fixed #1237097.A memory leak in Utility user feature has been fixed. Bug fixed #1166638.
Expanded Program Option Modifiers did not deallocate memory correctly. Bug fixed #1167487.
A server could crash due to a race condition between a
INNODB_CHANGED_PAGES
query and a bitmap file delete byPURGE CHANGED_PAGE_BITMAP
or directly on the file system. Bug fixed #1191580.Percona Server could not be built with Thread Pool feature and
-DWITH_PERFSCHEMA_ENGINE=OFF
option. Bug fixed #1196383.Building Percona Server with
-DHAVE_PURIFY
option would result in an error. Fixed by porting theclose_socket
function from MariaDB. Bug fixed #1203567.Adaptive hash index memory size was incorrectly calculated in
SHOW ENGINE INNODB STATUS
andInnodb_mem_adaptive_hash
status variable. Bug fixed #1218330.Some Expanded Program Option Modifiers didn’t have an effect if they were specified in non-normalized way (
innodb_io_capacity
vsinnodb-io-capacity
). Bug fixed #1233294.Enabling Enforcing Storage Engine feature could lead to error on Percona Server shutdown. Bug fixed #1233354.
Storage engine enforcement (
enforce_storage_engine
) is now ignored when the server is started in either bootstrap or skip-grant-tables mode. Bug fixed #1236938.Fixed the build warnings caused by User Statistics code on non-Linux platforms. Bug fixed #711817.
Adaptive hash indexing partitioning code has been simplified, potentially improving performance. Bug fixed #1218321.
Other bugs fixed: bug fixed #1239630, bug fixed #1191589, bug fixed #1200162, bug fixed #1214449, and bug fixed #1190604.
