- NOTICE_INBOX_SOURCE_* constants moved to common.php since Notice_inbox.php not always loaded
- fixed typo in User::staticGet() call which caused user #1 to receive messages once for each subscriber instead of for him/herself
- 'continue' -> 'continue 2' inside switch() statement to fix loop escape (PHP considers switch() a looping construct for break & continue)
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
(We need to keep it returning a reference because the extlib parent class is stuck in PHP 4-land and uses references everywhere, including this function's return value. Yuck!)
Also changed pkeyGet to drop the reference, since it doesn't have an upstream equivalent.
* added ProfileDeleteRelated event to match UserDeleteRelated, to allow plugins to add extra related tables on profile deletion
* UserFlagPlugin: deleting flags when target profile is deleted
* UserFlagPlugin: deleting flags when flagging user is deleted
* UserFlagPlugin: fix for autoloader -- class names are case-insensitive. We may get lowercase class names coming in at times, such as when creating DB objects programatically from a table name.
Note that any already-existing bogus entries need to be removed from the database:
select * from user_flag_profile where (select id from profile where id=profile_id) is null;
select * from user_flag_profile where (select id from user where id=user_id) is null;
In web interface and retweet/repeat API we show the original untrimmed text, but some back-compat API messages will still show the trimmed 'RT' version.
This matches Twitter's behavior on overlong retweets, though we're outputting the RT version in more API results than they do.
