Bugs Fixed¶
Fixed the potential cardinality 0 issue for TokuDB tables if ANALYZE
TABLE finds only deleted rows and no actual logical rows before it times
out. Bug fixed #1607300 (#1006, #732).
TokuDB database.table.index names longer than 256 characters could cause
server crash if background analyze table status was checked while running. Bug fixed
#1005.
PAM Authentication Plugin would abort authentication while checking UNIX user group membership if there were more than a thousand members. Bug fixed #1608902.
If DROP DATABASE would fail to delete some of the tables in the database,
the partially-executed command is logged in the binlog as DROP TABLE t1, t2,
... for the tables for which drop succeeded. A slave might fail to
replicate such DROP TABLE statement if there exist foreign key
relationships to any of the dropped tables and the slave has a different
schema from master. Fix by checking, on the master, whether any of the
database to be dropped tables participate in a Foreign Key relationship, and
fail the DROP DATABASE statement immediately. Bug fixed #1525407
(upstream #79610).
PAM Authentication Plugin didn’t support spaces in the UNIX user group names. Bug fixed #1544443.
Due to security reasons ld_preload libraries can now only be loaded from
the system directories (/usr/lib64, /usr/lib) and the MySQL
installation base directory.
In the client library, any EINTR received during network I/O was not handled correctly. Bug fixed #1591202 (upstream #82019).
SHOW GLOBAL STATUS was locking more than the upstream implementation which
made it less suitable to be called with high frequency. Bug fixed
#1592290.
The included .gitignore in the percona-server source distribution had
a line \*.spec, which means someone trying to check in a copy of the
percona-server source would be missing the spec file required to build the
RPMs. Bug fixed #1600051.
Audit Log Plugin did not transcode queries. Bug fixed #1602986.
If the changed page bitmap redo log tracking thread stops due to any reason, then shutdown will wait for a long time for the log tracker thread to quit, which it never does. Bug fixed #1606821.
Changed page tracking was initialized too late by InnoDB. Bug fixed #1612574.
Fixed stack buffer overflow if --ssl-cipher had more than 4000
characters. Bug fixed #1596845 (upstream #82026).
Audit Log Plugin events did not report the default database. Bug fixed #1435099.
Canceling the TokuDB Background ANALYZE TABLE job twice or while it was in the queue could lead to server assertion. Bug fixed #1004.
Fixed various spelling errors in comments and function names. Bug fixed #728 (Otto Kekäläinen)
Implemented a set of fixes to make PerconaFT build and run on the AArch64 (64-bit ARMv8) architecture. Bug fixed #726 (Alexey Kopytov).
Other bugs fixed: #1542874 (upstream #80296), #1610242, #1604462 (upstream #82283), #1604774 (upstream #82307), #1606782, #1607359, #1607606, #1607606, #1607671, #1609422, #1610858, #1612551, #1613663, #1613986, #1455430, #1455432, #1581195, #998, #1003, and #730.
