    PECL/mysqlnd_ms 1.1 series

    1.1.0

    • Release date:
      09/2011
    • Motto/theme: Cover
      replication basics with production quality

    The 1.1 and 1.0 series expose a similar feature
    set. Internally, the 1.1 series has been refactored to plan for
    future feature additions. A new configuration file format has been
    introduced, and limitations have been lifted. And the code quality
    and quality assurance has been improved.

    Feature changes

    • Added the (chainable) filter concept:

      • BC break: mysqlnd_ms_set_user_pick_server() has
        been removed. Thehttp://svn.php.net/viewvc/pecl/mysqlnd_ms/trunk/
        user
        filter has been introduced to replace it. The filter offers similar
        functionality, but see below for an explanation of the
        differences.
    • New powerful
      JSON based
      configuration syntax.
    • Lazy connections
      improved
      : security relevant, and state changing commands are
      covered.
    • Support for (native)
      prepared statements.
    • New statistics: use_master_guess,
      use_slave_guess.

      • BC break: Semantics of
        statistics changed for use_slave, use_master.
        Future changes are likely. Please see, mysqlnd_ms_get_stats().
    • List of broadcasted
      messages extended by ssl_set.
    • Library calls now
      monitored to remember settings for lazy connections:
      change_user, select_db, set_charset,
      set_autocommit.
    • Introduced mysqlnd_ms.disable_rw_split. The
      configuration setting allows using the load balancing and lazy
      connection functionality independently of read write
      splitting.

    Bug fixes

    • Fixed PECL #22724 –
      Server switching (mysqlnd_ms_query_is_select() case
      sensitive)
    • Fixed PECL #22784 –
      Using mysql_connect and mysql_select_db did not work
    • Fixed PECL #59982 –
      Unusable extension with –enable-mysqlnd-ms-table-filter. Use of
      the option is NOT supported. You must not used it. Added note to
      m4.
    • Fixed Bug #60119 –
      host=”localhost” lost in
      mysqlnd_ms_get_last_used_connection()

    The mysqlnd_ms_set_user_pick_server() function
    was removed, and replaced in favor of a new user filter.
    You can no longer set a callback function using mysqlnd_ms_set_user_pick_server() at
    runtime, but instead have to configure it in the plugins
    configuration file. The user filter will pass the same
    arguments to the callback as before. Therefore, you can continue to
    use the same procedural function as a callback.callback It is no
    longer possible to use static class methods, or class methods of an
    object instance, as a callback. Doing so will cause the function
    executing a statement handled by the plugin to emit an
    E_RECOVERABLE_ERROR level error,
    which might look like: “(mysqlnd_ms) Specified callback
    (picker) is not a valid callback
    .” Note: this may halt your
    application.
