Percona Server 5.5.43-37.2¶
Based on MySQL 5.5.43, including all the bug fixes in it, Percona Server 5.5.43-37.2 is now the current stable release in the 5.5 series. All of Percona‘s software is open-source and free, all the details of the release can be found in the 5.5.43-37.2 milestone at Launchpad.
A server binary as distributed in binary tarballs could fail to load on different systems due to an unsatisfied
libssl.so.6dynamic library dependency. This was fixed by replacing the single binary tarball with multiple tarballs depending on the OpenSSL library available in the distribution: 1) ssl100 - for all Debian/Ubuntu versions except Squeeze/Lucid (
libssl.so.1.0.0 => /usr/lib/x86_64-linux-gnu/libssl.so.1.0.0 (0x00007f2e389a5000)); 2) ssl098 - only for Debian Squeeze and Ubuntu Lucid (
libssl.so.0.9.8 => /usr/lib/libssl.so.0.9.8 (0x00007f9b30db6000)); 3) ssl101 - for CentOS 6 and CentOS 7 (
libssl.so.10 => /usr/lib64/libssl.so.10 (0x00007facbe8c4000)); 4) ssl098e - to be used only for CentOS 5 (
libssl.so.6 => /lib64/libssl.so.6 (0x00002aed5b64d000)). Bug fixed #1172916.
mysql_install_dbwould make the server produce an “
Error in my_thread_global_end(): 1 threads didn't exit” error message. While this error does not prevent
mysql_install_dbfrom completing successfully, its presence might cause any
mysql_install_db-calling script to return an error as well. This is a regression introduced by backporting fix for bug #1319904. Bug fixed #1402074.
A string literal containing an invalid UTF-8 sequence could be treated as falsely equal to a UTF-8 column value with no invalid sequences. This could cause invalid query results. Bug fixed #1247218 by a fix ported from MariaDB (MDEV-7649).
.debbinaries were built without fast mutexes. Bug fixed #1433980.
audit_log_filewould point to random memory area if the Audit Log Plugin was not loaded into server, and then installed with
INSTALL PLUGIN, and
audit_log_filesetting. Bug fixed #1437505.
Percona Server client
.debpackages were built with with
Readline. Further, a client built with
EditLinecould display incorrectly on PuTTY SSH client after its window resize. Bugs fixed #1266386 and #1332822 (upstream #63130 and #69991).
