Bugs Fixed¶

After installing the auth_socket plugin any local user might get root access to the server. If you’re using this plugin upgrade is advised. This is a regression, introduced in Percona Server 5.5.31-30.3. Bug fixed #1289599.

The new client and server packages included files with paths that were conflicting with the ones in mysql-libs package on CentOS. Bug fixed #1278516.

A clean installation of Percona-Server-server-55 on CentOS would fail due to a typo in mysql_install_db call. Bug fixed #1291247.

Percona-Server-shared-55 package was still declared as providing mysql-libs, but it is not actually providing it anymore. Bug fixed #1291249.

Slave I/O thread wouldn’t attempt to automatically reconnect to the master after a network time-out (error: 1159). Bug fixed #1268729 (upstream #71374).

Slave I/O thread wouldn’t attempt to automatically reconnect to the master if setting master_heartbeat_period failed with a transient network error. Bug fixed #1268735 (upstream #71375).

Renaming the libmysqlclient to libperconaserverclient¶

This release fixes some of the issues caused by the libmysqlclient rename to libperconaserverclient in Percona Server 5.5.36-34.0. The old name was conflicting with the upstream libmysqlclient.

Except for packaging, libmysqlclient and libperconaserverclient of the same version do not have any differences. Users who previously compiled software against Percona-provided libmysqlclient will either need to install the corresponding package of their distribution, such as mysql-lib for CentOS and libmysqlclient18 for Ubuntu/Debian or recompile against libperconaserverclient. Another workaround option is to create a symlink from libperconaserverclient.so.18.0.0 to libmysqlclient.so.18.0.0.
