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.
The only reason it worked was because DB fetches calls to get$varname if
the dataobject has a variable with the specific name. However, it started
blurting out errors that the case must be correct (which would require
'geturl' to be the function name).
Since we probably want to replace DB sometime, we'll just override this
auto-fetching mechanism and use more explicitly defined functions.
Avoiding collisions with date (shorter than before) and 4 character
random alphanumeric string. I bet someone could mass-upload files
and generate all combinations of aaaa-zzzz during the course of a
day, but then maybe that user should be disabled anyway :)
(filling the collision space will cause a never-ending loop).
The exception thrown from MediaFile will be caught and simply result in
no thumbnail at all right now. In the future we might use a catch-all
and have a "cannot generate preview"-icon or something.
VideoThumbnails requires php5-ffmpeg and php5-gd.
Actions have $this->scoped as the current profile which we can gladly
replace all the $cur=common_current_user() with.
And we want the prepare/handle functions to be protected. Plus only
the prepare function uses $args (which _must_ be an array).
spl_autoload_register now calls the GNUsocial_class_autoload function
instead of us replacing the magic __autoload($cls). This means we can
queue up other autoload functions, such as the one now used for extlib
functions which exist directly in the 'extlib/' folder or have proper
namespacing (which our new Markdown class does).
