a3e484a0e8 Memcached_DataObject unnecessarily require_once'd itself 2010-01-22 10:46:11 -05:00

ec145b73fc Major refactoring of queue handlers to support running multiple sites in one 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

4cc9b183d7 Avoid spewing warnings about returning by reference on memcached cache 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.

78214c4e06 Exclude process-specific link & result cache references from serialized Memcached_Data_Object instances.
Should fix seemingly-random bugs due to destructor free()ing local resources by mistake.

53c86c43c4 Bringing Sphinx search support up to code: broken out to a plugin, now 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.

Evan Prodromou
9e16b7d89b Use mysql_set_charset for connection instead of SET NAMES
PHP doesn't get the info about the charset of the connection if
you use SET NAMES. So, we use the appropriate PHP function instead.

04ef1ba8ee change function headers to K&R style
Another huge change, for PEAR code standards compliance. Function
headers have to be in K&R style (opening brace on its own line),
instead of having the opening brace on the same line as the function
and parameters. So, a little perl magic found all the function
definitions and move the opening brace to the next line (properly
indented... usually).

eb2f9c98ac replace NULL with null
Another global search-and-replace update. Here, I've replaced the PHP
keyword 'NULL' with its lowercase version. This is another PEAR code
standards change.

edbc0c665c replace all tabs with four spaces
The PEAR coding standards decree: no tabs, but indent by four spaces.
I've done a global search-and-replace on all tabs, replacing them by
four spaces. This is a huge change, but it will go a long way to
getting us towards phpcs-compliance. And that means better code
readability, and that means more participation.
