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. Squashed commit of the following: commit 5257626c62750ac4ac1db0ce2b71410c5711cfa3 Author: Evan Prodromou <evan@status.net> Date: Mon Jan 25 14:56:41 2010 -0500 slightly better handling of blowing tag memory cache commit 8a22a3cdf6ec28685da129a0313e7b2a0837c9ef Author: Evan Prodromou <evan@status.net> Date: Mon Jan 25 01:42:56 2010 -0500 change 'distribute' to 'distrib' so not too long for dbqueue commit 7a063315b0f7fad27cb6fbd2bdd74e253af83e4f Author: Evan Prodromou <evan@status.net> Date: Mon Jan 25 01:39:15 2010 -0500 change handle_notice() to handle() in distributqueuehandler commit 1a39ccd28b9994137d7bfd21bb4f230546938e77 Author: Evan Prodromou <evan@status.net> Date: Mon Jan 25 16:05:25 2010 -0500 error with queuemanager commit e6b3bb93f305cfd2de71a6340b8aa6fb890049b7 Author: Evan Prodromou <evan@status.net> Date: Mon Jan 25 01:11:34 2010 -0500 Blow memcache at different point rather than one big function for Notice class commit 94d557cdc016187d1d0647ae1794cd94d6fb8ac8 Author: Evan Prodromou <evan@status.net> Date: Mon Jan 25 00:48:44 2010 -0500 Blow memcache at different point rather than one big function for Notice class commit 1c781dd08c88a35dafc5c01230b4872fd6b95182 Author: Evan Prodromou <evan@status.net> Date: Wed Jan 20 08:54:18 2010 -0500 move broadcasting and distributing to new queuehandler commit da3e46d26b84e4f028f34a13fd2ee373e4c1b954 Author: Evan Prodromou <evan@status.net> Date: Wed Jan 20 08:53:12 2010 -0500 Move distribution of notices to new distribute queue handler
2010-01-22XMPP queued output & initial retooling of DB queue manager to support ↵Brion Vibber
non-Notice objects. Queue handlers for XMPP individual & firehose output now send their XML stanzas to another output queue instead of connecting directly to the chat server. This lets us have as many general processing threads as we need, while all actual XMPP input and output go through a single daemon with a single connection open. This avoids problems with multiple connected resources: * multiple windows shown in some chat clients (psi, gajim, kopete) * extra load on server * incoming message delivery forwarding issues Database changes: * queue_item drops 'notice_id' in favor of a 'frame' blob. This is based on Craig Andrews' work branch to generalize queues to take any object, but conservatively leaving out the serialization for now. Table updater (preserves any existing queued items) in db/rc3to09.sql Code changes to watch out for: * Queue handlers should now define a handle() method instead of handle_notice() * QueueDaemon and XmppDaemon now share common i/o (IoMaster) and respawning thread management (RespawningDaemon) infrastructure. * The polling XmppConfirmManager has been dropped, as the message is queued directly when saving IM settings. * Enable $config['queue']['debug_memory'] to output current memory usage at each run through the event loop to watch for memory leaks To do: * Adapt XMPP i/o to component connection mode for multi-site support. * XMPP input can also be broken out to a queue, which would allow the actual notice save etc to be handled by general queue threads. * Make sure there are no problems with simply pushing serialized Notice objects to queues. * Find a way to improve interactive performance of the database-backed queue handler; polling is pretty painful to XMPP. * Possibly redo the way QueueHandlers are injected into a QueueManager. The grouping used to split out the XMPP output queue is a bit awkward. Conflicts: scripts/xmppdaemon.php

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

2010-01-04Ticket 2141: bugs with weighted popularity lists across year boundary.Brion Vibber
Consolidated several separate implementations of the same weighting algorithm into common_sql_weight() and fixed some bugs... For MySQL, now using timestampdiff() instead of subtraction for the comparison, so we get sane results when the year doesn't match, and utc_timestamp() rather than now() so we don't get negative ages for recent items with local server timezone. Unknown whether the same problems affect PostgreSQL, but note that it lacks the timestampdiff() SQL function.

2009-11-11Fix bug 1963: Web UI throws warnings during previously open login session ↵Brion Vibber
after user account is deleted common_logged_in() returned bogus results because it checks against null specifically, but common_current_user() was sticking 'false' into $_cur because that's what User::staticGet() returned from a failed lookup. Now we skip over a failed lookup here, so we keep null and all is well.
