Percona is glad to announce the release of Percona Server 5.6.30-76.3 on May 25, 2016. Download the latest version from the Percona web site or the Percona Software Repositories.
Based on MySQL 5.6.30, including all the bug fixes in it, Percona Server 5.6.30-76.3 is the current GA release in the Percona Server 5.6 series. Percona Server is open-source and free – this is the latest release of our enhanced, drop-in replacement for MySQL. Complete details of this release can be found in the 5.6.30-76.3 milestone on Launchpad.
Bugs Fixed:
- When Read Free Replication was enabled for TokuDB, and there was no explicit primary key for the replicated TokuDB table, there could be duplicated records in the table on update operation. The fix disables Read Free Replication for tables without an explicit primary key and does rows lookup for
UPDATE
andDELETE
binary log events and issues warning. Bug fixed #1536663 (#950). - Attempting to execute a non-existing prepared statement with Response Time Distribution plugin enabled could lead to a server crash. Bug fixed #1538019.
- TokuDB was using using different memory allocators; this was causing
safemalloc
warnings in debug builds and crashes because memory accounting didn’t add up. Bug fixed #1546538 (#962). - Fixed heap allocator/deallocator mismatch in Metrics for scalability measurement. Bug fixed #1581051.
- Percona Server is now built with system
zlib
library instead of the older bundled one. Bug fixed #1108016. - Reduced the memory overhead per page in the InnoDB buffer pool. The fix was based on Facebook patch #91e979e. Bug fixed #1536693 (upstream #72466).
CREATE TABLE ... LIKE ...
could create a system table with an unsupported enforced engine. Bug fixed #1540338.- Change buffer merge could throttle to 5% of I/O capacity on an idle server. Bug fixed #1547525.
Slave_open_temp_tables
would fail to decrement on the slave with a disabled binary log if the master was killed. Bug fixed #1567361.- The server will now show a more descriptive error message when Percona Server fails with
errno == 22 "Invalid argument"
, ifinnodb_flush_method
was set toALL_O_DIRECT
. Bug fixed #1578604. - Killed connection threads could get their sockets closed twice on shutdown. Bug fixed #1580227.
AddressSanitizer
build withLeakSanitizer
enabled was failing atgen_lex_hash
invocation. Bug fixed #1580993 (upstream #80014).apt-cache show
command forpercona-server-client
was showinginnotop
included as part of the package. Bug fixed #1201074.mysql-systemd
would fail with PAM authentication and proxies due to a regression introduced when fixing #1534825 in Percona Server 5.6.29-76.2. Bug fixed #1558312.- Upgrade logic for figuring if TokuDB upgrade can be performed from the version on disk to the current version was broken due to a regression introduced when fixing bug #684 in Percona Server 5.6.27-75.0. Bug fixed #717.
- If
ALTER TABLE
was run whiletokudb_auto_analyze
variable was enabled it would trigger auto-analysis, which could lead to a server crash ifALTER TABLE DROP KEY
was used because it would be operating on the old table/key meta-data. Bug fixed #945. - The TokuDB storage engine with
tokudb_pk_insert_mode
set to1
is safe to use in all conditions. OnINSERT IGNORE
orREPLACE INTO
, it tests to see if triggers exist on the table, or replication is active with!BINLOG_FORMAT_STMT
before it allows the optimization. If either of these conditions is met, then it falls back to the “safe” operation of looking up the target row first. Bug fixed #952. - Bug in TokuDB Index Condition Pushdown was causing
ORDER BY DESC
to reverse the scan outside of theWHERE
bounds. This would cause a query to hang in asending data
state for several minutes in some environments with large amounts of data (3 billion records) if theORDER BY DESC
statement was used. Bugs fixed #988, #233, and #534.
Other bugs fixed: #1399562 (upstream #75112), #1510564 (upstream #78981), #1496282 (#964), #1496786 (#956), #1566790, #1552673, #1567247, #1567869, #718, #914, #970, #971, #972, #976, #977, #981, #637, and #982.
