769febf22e DirectMessage added to default plugins
I think the migration from core to plugin is done now for DMs.

This is required since we support the Twitter-based API by default,
which is implemented in many of the mobile clients etc. But you can
disable the DirectMessage for your instance of you wish, of course.

db7cc7fa75 Favorite functionality put into plugin (not done yet)
Now we have to fix any code in the core which directly uses the Fave class
or any other favorite stuff, since it is pluginised and thus might not be
available on some installations.

202eaa53e0 Don't report all linked URLs to remote sites
noembed.com acts as a proxy for oEmbed requests, but that also means they
get all the links we post on our instances, given that they're used as a
default endpoint.

c93a5252c1 Don't show or preview text/html attachments
htmLawed cleans stuff out properly, but there's no very good way right
now to show text/html attachments, since everything gets jumbled up with
our own CSS etc. Best would be an iframe or just a new tab or so.

34114e87be OpportunisticQM moved from core to default plugins.
This makes it easier to disable, but remember that you must then
either enable and maintain queue daemons or disable queueing (and
handle whatever remaining queue items are stored in the database)!

d59eb5e184 Dynamically generate thumbnails (see full text)
The File object now stores width and height of files that can
supply this kind of information. Formats which we can not read
natively in PHP do not currently benefit from this. However an
event hook will be introduced later.

The CreateFileImageThumbnail event is renamed to:
CreateFileImageThumbnailSource to clarify that the hooks should not
generate their own thumbnails but only the source image. Also it now
accepts File objects, not MediaFile objects.

The thumbnail generation is documented in the source code. For
developers, call 'getThumbnail' on a File object and hope for the best.

Default thumbnail sizes have increased to be more appealing.

6faed0e451 MediaFile loses dependency on PEAR::MIME
At the same time we remove the "filecommand" setting, since we will
likely not have use of it thanks to PECL fileinfo.

Also the "supported" list for attachment mime types has changed
format, so we can keep track of at least some known file extensions.

c0c8250ff7 minify removed from core (use plugin if desired)
My reasoning: Minifying makes third party review harder. A visitor on
a GNU social site should have no problem reading, understanding and
modifying javascripts for their own liking. A minified script is much
more difficult to use, reuse, modify and share.

Free software is not minified.

0cd93c2761 Cron plugin added and now default queue handler
Generally the Cron plugin will run if there's still execution time for
1 second since starting the Action processing. If you want to change
this (such as disabling, 0 seconds, or maybe running bigger chunks,
for like 4 seconds) you can do this, where 'n' is time in seconds.

   addPlugin('Cron', array('secs_per_action', n));

Add 'rel_to_pageload'=>false to the array if you want to run the queue
for a certain amount of seconds _despite_ maybe already having run that
long in the previous parts of Action processing.

Perhaps you want to run the cron script remotely, using a machine capable
of background processing (or locally, to avoid running daemon processes),
simply do an HTTP GET request to the route /main/cron of your GNU social.
Setting secs_per_action to 0 in the plugin config will imply that you run
all your queue handling by calling /main/cron (which runs as long as it can).

/main/cron will output "0" if it has finished processing, "1" if it should
be called again to complete processing (because it ran out of time due to
PHP's max_execution_time INI setting).

The Cron plugin also runs events as close to hourly, daily and weekly
as you get, based on the opportunistic method of running whenever a user
visits the site. This means of course that the cron events should be as
fast as possible, not only to avoid delaying page load for users but
also to minimize the risk of running into PHP's max_execution_time. One
suggestion is to only use the events to add new queue items for later processing.

These events are called CronHourly, CronDaily, CronWeekly - however there
is no guarantee that all events will execute, so some kind of failsafe,
transaction-ish method must be implemented in the future.

e45edd6ae2 Use addPlugin! (esp. XMPP folks should do this)
If you're using XMPP by setting $config['xmpp'][*] then you should do:

    addPlugin('Xmpp', $config['xmpp']);

because setting it directly in $config[''] won't do anything.

Also, default resource for XMPP is now 'gnusocial'. If you want something
more random, set it in your addPlugin config array.

2a5ba1f74b Core and Default plugins separated, now loads on install
_flow_ reported on IRC that install.php had stopped working. This was
because default plugins had been put into two separate lists, and the
list with AuthCrypt was never loaded when performing an installation.

Core plugins cannot be disabled.

I also removed the Memcache autodetection thing since it should be
solved in a more elegant manner.

de7726dd00 Performance counters: records number of total and unique cache get/set/incr/deletes and queries, and logs to syslog.
$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)

004d58fdb8 Make code-dependent cache entries more volatile
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.

197b56778a Add $config['attachments']['process_links'] to allow disabling processing of mentioned URL links for attachment info (oEmbed lookups) and dereferencing of redirects that we didn't have shortened ourselves.
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.

cb124fe831 Add a quick config setting to disable/enable display of thumbnails in regular notice lists (attachments/show_thumbs) - disabling gives the same display as before this feature was added (but changes to oembed handling are still there, and the lightbox popup is gone) 2010-11-12 12:24:55 -08:00

694448e0aa Add attachments 'thumb_width' and 'thumb_height' settings for inline thumbs, defaulting to 100x75.
This is used as the max thumb width/height for oEmbed requests (replacing the old default of 500x400 which was more suitable for the lightbox).

54c88cba57 Add a $config['plugins']['locale_path'] which can be set to override the individual plugins' locale subdirectories.
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.
