$config['site']['logperf'] = true; // to record & dump total hits of each type and the runtime to syslog
$config['site']['logperf_detail'] = true; // very verbose -- dump the individual cache keys and queries as they get used (may contain private info in some queries)
Seeing 180 cache gets on a timeline page seems not unusual currently; since these run in serial, even relatively small roundtrip times can add up heavily.
We should consider ways to reduce the number of round trips, such as more frequently storing compound objects or the output of processing in memcached.
Doing parallel multi-key lookups could also help by collapsing round-trip times, but might not be easy to fit into SN's object model. (For things like streams this should actually work pretty well -- grab the list, then when it's returned go grab all the individual items in parallel and return the list)
We can make a lot of HTTP requests from the server side. This change
adds some configuration options for using an HTTP proxy, which can
cache hits from multiple sites (good for status.net-like services, for example).
If a cache entry is dependent on the code that's running, upgrading
(or enabling/disabling plugins) can generate hard-to-track
inconsistencies.
This change adds a close-to-unique fingerprint of the running code to
some cache keys, so that if the fingerprint changes, the old values
are ignored and new values are used.
If the automated uniqueness fails, an administrator can add an extra
config value, $config['site']['build'], that's thrown into the key also.

This option may be useful for intranet sites that don't have direct access to the internet, as they may be unable to successfully fetch those resources.
This will apply to *ALL* plugins in *ALL* languages, so should probably only be used when doing site customization...
You'd probably do:
$config['site']['locale_path'] = '/srv/awesome/data/locale';
$config['plugins']['locale_path'] = '/srv/awesome/data/locale';
with a structure like:
srv/
awesome/
data/
locale/
en/
LC_MESSAGES/
statusnet.po
OpenID.po
AnonymousFave.po
etc, all alongside each other. You could separate plugins from the core if you like.
Where locale files have not already been generated, you can build one for a plugin like so:
php scripts/update_po_templates.php --plugin=MyPlugin
and pull out the template file:
plugins/MyPlugin/locale/MyPlugin.pot
Edit that (make sure you at least set the CHARSET, probably to UTF-8) and save your customized .po
files into the structure as above, and use msgfmt to generate .mo files for final output.
Two prongs here:
* We attempt to enable SNI on the SSL stream context with the appropriate hostname... This requires PHP 5.3.2 and OpenSSL that supports the TLS extensions. Unfortunately this doesn't seem to be working in my testing.
* If set $config['http']['curl'] = true, we'll use the CURL backend if available. In my testing on Ubuntu 10.04, this works. No guarantees on other systems.
I'm not enabling CURL mode by default just yet; want to make sure there's no other surprises.
Currently only one custom theme may be uploaded per site, saved with the name 'custom' and stored into the local/themes subdirectory.
Administrators can upload a .ZIP archive containing a theme through the design admin panel; its contents are validated to ensure that only legit files are saved, and a 5M size quota is enforced.
Theme upload requires the zip extension for PHP; if not present, theme uploading is disabled by default.
Uploading and the custom CSS can be controlled via $config['theme_upload']['enabled'] and $config['custom_css']['enabled'].
Configurable directory/path/server for 'local' subdirectory (currently only as used for themes; local plugins not yet switched over)
Can set $config['local']['dir'] etc; not currently exposed in the admin panels.
Per-site directories on a separate themes server could be set up such as:
$config['local']['dir'] = '/path/to/themes/local/' . $_nickname;
$config['local']['server'] = 'themes.example.com';
$config['local']['path'] = '/local/' . $_nickname;
$config['local']['ssl'] = 'never';
Added a 2-second default timeout for XMLRPC/extended pings, configurable as [ping,timeout].
No longer repeating the entire ping section if we had an HTTP error during a submission.
For now, dropping the bad item and continuing on with others. (Todo: individual retry and cleaner discards of blacklisted broken-for-now sites.)
I swapped the settings from negative to positive ($config['queue']['stomp_transactions'] = false rather than $config['queue']['stomp_no_transactions'] = true), gave them defaults (both on for best ActiveMQ experience), and added notes to the README about configuring them.
- switch 'en_US' to 'en', fixes the "admin panel switches to Arabic" bug
- tweak setting descriptions to clarify that most of the time we'll be using browser language
- add a backend switch to disable language detection (should this be exposed to ui?)
We've been making pretty crummy tag: URIs for a while. We should
continue to favor HTTP URIs, since it's nice to be able to discover
things about an object you've shared the ID of. Where that's not
possible, this makes nicer tag URIs.
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
