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
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.

Allows storage of larger objects (over 1mb in size uncompressed), such as huge LDAP schemas.
Should also improve cache efficiency (allows more stuff to be stored in same memory) and reduce network latency (less data transfer)
Added EmailAuthenticationPlugin
Added ReverseUsernameAuthenticationPlugin
Changed the StartChangePassword and EndChangePassword events to take a user, instead of a nickname
User::allowed_nickname was declared non-static, but used as if it was static, so I made the declaration static
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.
* 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.
Set "en_US" locale first, then the locale we want for our user.
This seems to initialize gettext properly somehow, which I could see when the languages would come up briefly on settings save when changing from a supported language.
Definitely works for ga_ES on my Ubuntu system (8.10 intrepid), hopefully reasonably consistent.
This reverts commit 20997619b3.
The commit doesn't take into account having different servers (theme
server, avatar server) and being able to set HTTPS for some but not all.
* If no shortener plugin is enabled, fall back to using the long URL instead of trying to load nonexistent ur1.ca plugin and throwing 'Class does not exist'
* Fix bad call to call_user_func_array() in callback_helper() which broke all shortening
This reverts commit e2848eb862.
Downstream consumers of our notices (such as Friendfeed, Facebook, etc) don't have sophisticated URL detection, so a notice that reads: "check out ur1.ca/1" won't be linked. So the http:// prefix is
mandatory.
Undefined index: HTTP_X_FORWARDED_FOR
Undefined index: HTTP_CLIENT_IP
Undefined variable: proxy
Also fixed the return value order to match calls to common_client_ip() in actions/api.php and lib/rssaction.php
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.
