New Features

TokuDB MTR suite is now part of the default MTR suite in Percona Server for MySQL 5.7.

Bugs Fixed

Querying the GLOBAL_TEMPORARY_TABLES table would cause a server crash if temporary table owning threads would execute new queries. Bug fixed #1581949.

IMPORT TABLESPACE and undo tablespace truncate could get stuck indefinitely with a writing workload in parallel. Bug fixed #1585095.

Requesting to flush the whole of the buffer pool with doublewrite parallel buffer wasn’t working correctly. Bug fixed #1586265.

Audit Log Plugin would hang when trying to write a log record of audit_log_buffer_size length. Bug fixed #1588439.

Audit log in ASYNC mode could skip log records that don’t fit into the log buffer. Bug fixed #1588447.

In order to support innodb_flush_method being set to ALL_O_DIRECT, the log I/O buffers were aligned to innodb_log_write_ahead_size. This missed that the variable is dynamic and could still cause the server to crash. Bug fixed #1597143.

InnoDB tablespace import would fail when trying to import a table with a different data directory. Bug fixed #1548597 (upstream #76142).

The Audit Log plugin was truncating SQL queries to 512 bytes. Bug fixed #1557293.

mysqlbinlog did not free the existing connection before opening a new remote one. Bug fixed #1587840 (upstream #81675).

Fixed a memory leak in mysqldump. Bug fixed #1588845 (upstream #81714).

Transparent Huge Pages check will now only happen if tokudb_check_jemalloc option is set. Bugs fixed #939 and #713.

Logging in ydb environment validation functions now prints more useful context. Bug fixed #722.

Other bugs fixed: #1541698 (upstream #80261), #1587426 (upstream, #81657), #1589431, #956, #964,
