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 explicit primary key and does rows lookup for UPDATE and DELETE 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 disabled binary log if master was killed. Bug fixed #1567361.

Server will now show more descriptive error message when Percona Server fails with errno == 22 "Invalid argument", if innodb_flush_method was set to ALL_O_DIRECT. Bug fixed #1578604.

Killed connection threads could get their sockets closed twice on shutdown. Bug fixed #1580227.

AddressSanitizer build with LeakSanitizer enabled was failing at gen_lex_hash invocation. Bug fixed #1580993 (upstream #80014).

apt-cache show command for percona-server-client was showing innotop included as part of the package. Bug fixed #1201074.

mysql-systemd would fail with PAM authentication and proxies due to 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 regression introduced when fixing #684 in Percona Server 5.6.27-75.0. Bug fixed #717.

If ALTER TABLE was run while tokudb_auto_analyze variable was enabled it would trigger auto-analysis, which could lead to a server crash if ALTER 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 to 1 is safe to use in all conditions. On INSERT IGNORE or REPLACE 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 are 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 the WHERE bounds. This would cause query to hang in a sending data state for several minutes in some environments with large amounts of data (3 billion records) if the ORDER 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.
