2010-02-16Stomp queue restructuring for mass scalability:Brion Vibber
- 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
2010-02-05Don't spew warnings on usage of MEMCACHE_COMPRESSED constant when memcache ↵Brion Vibber
PHP extension is not present. Switched to a locally-defined Cache::COMPRESSED, translating that to MEMCACHE_COMPRESSED in the plugin.

2010-01-25Offload inbox updates to a queue handler to speed up posting onlineEvan Prodromou
Moved much of the writing that happens when posting a notice to a new queuehandler, distribqueuehandler. This updates tags, groups, replies and inboxes at queue time (or at Web time, if queues are disabled). To make this work well, I had to break up the monolithic Notice::blowCaches() and make cache blowing happen closer to where data is updated.

2010-01-24Recover caching logic lost in bad mergeEvan Prodromou
I made a bad merge on Jan 10th from master to 0.9.x. This lost a number of memcache enhancements made on the 0.9.x branch. I've been able to re-do the manual merge, and this represents the changes. Most of them are related to caching on insert.

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
2010-01-12Avoid spewing warnings about returning by reference on memcached cache ↵Brion Vibber
misses by setting a var and returning it instead of trying to return false directly. This hacky workaround is brought to you by DB_DataObject's PHP 4 roots.

Memcached_Data_Object instances. Should fix seemingly-random bugs due to destructor free()ing local resources by mistake. cherry-pick from 0.9.x

2009-12-14Add destructor on Memcached_DataObject to free DB_DataObject's global ↵Brion Vibber
storage for an object when that object itself is destroyed. Reduces some, but not all, memory leakage for long-running processes.

down to Memcached_DataObject::cacheKey() via various fetch functions, need a backtrace to track it down.
2009-11-10Bringing Sphinx search support up to code: broken out to a plugin, now ↵Brion Vibber
supports multiple sites on a single server. Upgrade notes: * Index names have changed from hardcoded 'Identica_people' and 'Identica_notices' to use the database name and actual table names. Must reindex. New events: * GetSearchEngine to override default search engine class selection from plugins New scripts: * gen_config.php generates a sphinx.conf from database configuration (with theoretical support for status_network table, but it doesn't seem to be cleanly queriable right now without knowing the db setup info for that. Needs generalized support.) * Replaced old sphinx-indexer.sh and sphinx-cron.sh with index_update.php Other fixes: * sphinx.conf.sample better matches our live config, skipping unused stopword list and using a more realistic indexer memory limit Further notes: * Probably doesn't work right with PostgreSQL yet; Sphinx can pull from PG but the extraction queries currently look like they use some MySQL-specific functions.

This reverts commit 84072aa5cf6124d59a06a7f0a7945c00ee2836da. This commit caused grievous harm to old notices on identi.ca. Reverting until we figure out how to convert the old notices.
