DROP DATABASEwould 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 TABLEstatement 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 DATABASEstatement immediately. Bug fixed #1525407 (upstream #79610).
Due to security reasons
ld_preloadlibraries can now only be loaded from the system directories (
/usr/lib) and the MySQL installation base directory.
SHOW GLOBAL STATUSwas locking more than the upstream implementation which made it less suitable to be called with high frequency. Bug fixed #1592290.
.gitignorein 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.
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 various spelling errors in comments and function names. Bug fixed #728 (Otto Kekäläinen)
