- Multiplexing queues into groups and for multiple sites. - Sharing vs breakout configurable per site and per queue via $config['queue']['breakout'] - Detect how many times a message is redelivered, discard if it's killed too many daemons - count configurable with $config['queue']['max_retries'] - can dump the items to files in $config['queue']['dead_letter_dir'] Queue daemon memory & resource leak fixes: - avoid unnecessary reconnections to memcached server (switch persistent connections back in on second initialization, assuming it's child process) - monkey-patch for leaky .ini loads in DB_DataObject::databaseStructure() - was leaking 200k per active switch - applied leak fixes to Status_network as well, using intermediate base Safe_DataObject for both it and Memcache_DataObject Misc queue fixes: - correct handling of child processes exiting due to signal termination instead of regular exit - shutdown instead of infinite respawn loop if we're already past the soft memory limit at startup - Added --all option for xmppdaemon... still opens one xmpp connection per site that has xmpp active Cache updates: - add Cache::increment() method with native support for memcached atomic increment
