Functionality Added or Changed

Bugs Fixed

  • Bug #689830 – The development environment tests of show_slave_status_nolock work only on statement-based replication. They were failing when row-based replication was attempted. A check is now made for the replication type to test. (Oleg Tsarev)

  • Something seems to have changed in the package dependencies. Was this intentional?

    # rpm -U Percona-Server-shared-51-5.1.54-rel12.5.188.rhel5.x86_64.rpm

  • Does ALL_O_DIRECT apply to both redo and binary logs? Great feature by the way, lets you use that extra memory that would have been otherwise wasted on unnecessary Linux buffer caching.

  • Mike,

    Binary logs are written by MySQL SQL layer not Innodb engine so this setting does not apply to it.

  • Peter, the “Downloads – binary distributions” is wrongly linked to the previously version (12.4)

  • Aleksandr Kuzminsky

    Lance,

    Thanks for the report – fixed.

    JS,

    Indeed, library files were moved from -server to more appropriate -shared package.
    To successfully update Percona-Server packages you need to update Percona-Server-shared-51 and Percona-Server-server-51 simultaneously either with YUM or rpm command:
    # yum update Percona-Server-server-51 Percona-Server-shared-51
    or
    # rpm -Uhv Percona-Server-shared-51-5.1.54-rel12.5.188.rhel5.x86_64.rpm Percona-Server-server-51-5.1.54-rel12.5.188.rhel5.x86_64.rpm

  • It seems necessary to add “Provides: virtual-mysql-client” to package percona-server-client in debain version. Some packages depend on this. Example:
    $apt-cache showpkg cacti

    Dependencies: … virtual-mysql-client.

    jetstalker,

    That makes sense. I filed a bug, it will be resolved in the nearest release.

    Thanks!

  • Although not generally the best idea you can create a dummy package to get cacti installed:

    apt-get install equivs
    equivs-control dummy-mysql-virtual-client.ctl

    — edit dummy-mysql-virtual-client.ctl and make sure `Package:` line looks like:
    Package: virtual-mysql-client

    equivs-build dummy-mysql-virtual-client.ctl
    dkpg -i mysql-virtual-client.deb
