Percona Server 5.5.50-38.0¶

New Features¶

Percona Server has implemented protocol support for TLS 1.1 and TLS 1.2. This implementation turns off TLS v1.0 support by default.

Bugs Fixed¶

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

The innodb_log_block_size feature attempted to diagnose the situation where the logs have been created with a log block value that differs from the current innodb_log_block_size setting. But this diagnostics came too late, and a misleading error No valid checkpoints found was produced first, aborting the startup. Bug fixed #1155156.

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

ssl.cmake file was broken when custom OpenSSL build was used. Bug fixed #1582639 (upstream #61619).

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

Fixed memory leaks in mysqltest. Bugs fixed #1582718 and #1588318.

Fixed memory leaks in mysqlcheck. Bug fixed #1582741.

Fixed memory leak in mysqlbinlog. Bug fixed #1582761 (upstream #78223).

Fixed memory leaks in mysqldump. Bug fixed #1587873 and #1588845 (upstream #81714).

Fixed memory leak in innochecksum. Bug fixed #1587873.

Fixed memory leak in non-existing defaults file handling. Bug fixed #1588344.
