2010-01-12Major refactoring of queue handlers to support running multiple sites in one ↵Brion Vibber
daemon. Key changes: * Initialization code moved from common.php to StatusNet class; can now switch configurations during runtime. * As a consequence, configuration files must now be idempotent... Be careful with constant, function or class definitions. * Control structure for daemons/QueueManager/QueueHandler has been refactored; the run loop is now managed by IoMaster run via scripts/queuedaemon.php IoManager subclasses are woken to handle socket input or polling, and may cover multiple sites. * Plugins can implement notice queue handlers more easily by registering a QueueHandler class; no more need to add a daemon. The new QueueDaemon runs from scripts/queuedaemon.php: * This replaces most of the old *handler.php scripts; they've been refactored to the bare handler classes. * Spawns multiple child processes to spread load; defaults to CPU count on Linux and Mac OS X systems, or override with --threads=N * When multithreaded, child processes are automatically respawned on failure. * Threads gracefully shut down and restart when passing a soft memory limit (defaults to 90% of memory_limit), limiting damage from memory leaks. * Support for UDP-based monitoring: http://www.gitorious.org/snqmon Rough control flow diagram: QueueDaemon -> IoMaster -> IoManager QueueManager [listen or poll] -> QueueHandler XmppManager [ping & keepalive] XmppConfirmManager [poll updates] Todo: * Respawning features not currently available running single-threaded. * When running single-site, configuration changes aren't picked up. * New sites or config changes affecting queue subscriptions are not yet handled without a daemon restart. * SNMP monitoring output to integrate with general tools (nagios, ganglia) * Convert XMPP confirmation message sends to use stomp queue instead of polling * Convert xmppdaemon.php to IoManager? * Convert Twitter status, friends import polling daemons to IoManager * Clean up some error reporting and failure modes * May need to adjust queue priorities for best perf in backlog/flood cases Detailed code history available in my daemon-work branch: http://www.gitorious.org/~brion/statusnet/brion-fixes/commits/daemon-work

2009-10-23Fix three fatal errors when posting from 0.9.x:Brion Vibber
* OMB remote updates were trying to load nonexistent Laconica_OMB_Service_Consumer class -- fixed to StatusNet_OMB_Service_Consumer. Regression caused during libomb merge. * Twitter processing was still being queued from core when no twitter plugin was present, which triggered an exception from UnqueueHandler; leftover code from before the plugin extraction. * UnqueueHandler's exception caused a fatal error instead because it was missing the "new" keyword. Wouldn't have been seen when testing with the plugin enabled.

2009-07-01Add UnQueueManager for immediate handlingEvan Prodromou
Perhaps it's a little precious, but I took out the switches in util.php to determine what's supposed to be sent when, and made a queuemanager class that will just do things when they're supposed to be done.
