One of the problems we've had with running large-scale hosting systems
for StatusNet is enabling new plugins. If the plugin is not enabled,
its database tables are not checked at script time. Conversely, if it
is enabled, it may take several hours to run checkschema for tens of
thousands of sites -- during which time users might see DB errors.
A new argument to checkschema lets it pre-load one or more plugins
before checking the schema. This lets us prepare the plugins' database
tables before they're used in production. In a multihome environment,
this can be combined with tags to gradually roll out a new plugin.
In the config file, a stanza like:
$site = Status_network::getFromHostname(...);
if ($site->hasTag('fooenabled')) {
addPlugin('Foo');
}
...will only enable the plugin on certain sites. Meanwhile, a bash
script like this should gradually enable the plugin:
# For all sites...
for site in `php allsites.php`; do
# Update the schema for the Foo plugin
php checkschema.php -s$site.wildcard -xFoo;
# Enable the Foo plugin
php settag.php -s$site.wildcard fooenabled;
done
like leprous boils in our code. So, I've replaced all of them with //
comments instead. It's a massive, meaningless, and potentially buggy
change -- great one for the middle of a release cycle, eh?
UserActivityStream -- used to create a full activity stream including subscriptions, favorites, notices, etc -- normally buffers everything into memory at once. This is infeasible for accounts with long histories of serious usage; it can take tens of seconds just to pull all records from the database, and working with them all in memory is very likely to hit resource limits.
This commit adds an alternate mode for this class which avoids pulling notices until during the actual output. Instead of pre-sorting and buffering all the notices, empty spaces between the other activities are filled in with notices as we're making output. This means more smaller queries spread out during operations, and less stuff kept in memory.
Callers (backupaccount action, and backupuser.php) which can stream their output pass an $outputMode param of UserActivityStream::OUTPUT_RAW, and during getString() it'll send straight to output as well as slurping the notices in this extra funky fashion.
Other callers will let it default to the OUTPUT_STRING mode, which keeps the previous behavior.
There should be a better way to do this, swapping out the stringer output for raw output more consitently.
Moved most of the heavy-lifting for account restoration out of
restoreuser.php and into its own class, with the hope that we'll do
the work from the Web eventually.
common_shorten_links() can only access the web session's logged-in user, so never properly took user options into effect for posting via XMPP, API, mail, etc.
Adds an optional $user parameter on common_shorten_links(), and a $user->shortenLinks() as a clearer interface for that.
Tweaked some lower-level functions so $user gets passed down -- making the $notice_id param previously there for saving URLs at notice save time generalized a little.
Note also ticket #2919: there's a lot of duplicate code calling the shortening, checking the length, and reporting near-identical error messages. These should be consolidated to aid in code and translation maintenance.
* add some sanity checking: abort on failures instead of plodding through
* add some progress / error output
* fetch the target database server name from the status_network entry and use that to target the DROP DATABASE
Note that database names and other overrides in status_network entry may still not be seen.
* Moved notification sending from Notice::saveReplies to distrib queue handler, so it'll pull from the reply set we've saved regardless of how we got it.
* Set up gettext infrastructure for command-line scripts; gets localization mail notifications etc working from background queues.
* Adjusted locale switching: common_switch_locale() works at runtime for bg scripts, forces a message catalog update
May be slow or run out of memory if run on particularly prolific posters -- not yet optimized for that case.
Note that geodata that has already been sent out to other services (via ostatus, omb, twitter, etc) will not be removed from them.
(fixed version -- previous had accidentally undone another commit)

* added locale/en/LC_MESSAGES/statusnet.po to make it easier to start customizing English texts
* added notes to locale/README about customizing and how to disable languages you haven't customized
* renamed PO templates from *.po to *.pot to match general conventions and reduce confusion for people trying to find which file they're supposed to edit
Keeps stray daemon subprocesses from floating around when we kill the parents via a signal!
Accomplished by opening a bidirectional pipe in the parent process; the children close out the writer end and keep the reader in their open sockets list. When the parent dies, the children see that the socket's been closed out and can perform an orderly shutdown.
It was only finding the first two avatars and then thinking it was done.
I'm not entirely sure why it was doing that.
I think maybe all the cloning made it forget where it was or something.
Either way, it seems to work now, and really uses less memory.
All breakout queues that we're going to need to listen to now need to be explicitly listed in $config['queue']['breakout'].
Until XMPP is moved to component model, this setting will let the individual processes work with their own queues:
$config['queue']['breakout'][] = 'xmpp/xmppout/' . $config['site']['nickname'];
- 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
May miss keys other than the given or primary key, but should work for a lot of common cases where a bad entry's been removed from DB but lingers in cache.
Email and tag params added to the end:
setup_status_net.sh mysite 'My Site' 'owner@example.com' '1user'
(If multiple tags are needed, separate them with a pipe "|". Be sure to quote properly!)
New parameters for setup.cfg need to be set:
export PHPBASE=/var/www/statusnet
export WILDCARD=example.net
export MAILTEMPLATE=/etc/statusnet/newsite-mail.txt
export MAILSUBJECT="Your new StatusNet site"
$PHPBASE is the base dir for a callable StatusNet install, used to run command-line scripts for user setup.
$WILDCARD is the wildcard domain, needed to build a full server name to pass into command-line scripts.
$MAILTEMPLATE points to a file containing an e-mail message template. '$nickname', '$sitename', and '$userpass' can be used in the template for substitution.
$MAILSUBJECT is the subject line for said email.
To skip sending an email on creation, leave $MAILTEMPLATE blank or point to a non-existing file.

Add persistent:true property to Stomp messages so ActiveMQ doesn't decide to discard them even though persistence is enabled on the broker. :) (Thanks Aric!)
quick fix: use common_path() on realtime update JS so it works with the new JS path code (will pull from main server for now)

Default control channel is /topic/statusnet-control. For external utilities to send a site update ping direct to the queue server, connect via Stomp and send a message formatted thus:
update:<nickname>
(Nickname here, *not* server hostname! The rest of the queues will be updated to use nicknames later.)
Note that all currently-connected queue daemons will get these notifications, including both queuedaemon.php and xmppdaemon.php. (XMPP will ignore site update requests for sites that it's not handling.)
Limitations:
* only implemented for stomp queue manager so far
* --update may not yet handle a changed server name properly
* --restart won't reload PHP code files that were already loaded at startup. Still need to stop and restart the daemons from 'outside' when updating code base.
