The code was so involved there was even a comment asking for a refactor.
Now, File_redirection::where always returns a nice File_redirection
object instead of an array or string or nothing. The object is
either one which already existed or else a new, unsaved object.
Instead of duplicating "does it exist" checks everywhere, do it in
File_redirection::where. You either get what exists or something to save.
An unsaved File_redirection may be paired with an unsaved File.
You will want to save the File first (using ->saveFile()) and put the
id in File_redirection#file_id before saving.
If a new file is uploaded, it will be matched with a previously uploaded
file so we don't have to store duplicates. SHA256 is random enough and
also unlikely enough to cause collisions.
If this merge throws exception on scripts/upgrade.php and you recently
tried a nightly (i.e. during 2015-02-19) then just go back a commit or two
and try again.
Or delete the duplicate entries. Find the entries like this:
SELECT COUNT(*), urlhash FROM file_redirection
GROUP BY urlhash
HAVING COUNT(*) > 1;
then for each urlhash (or come up with a smart SQL query) do:
DELETE FROM file_redirection WHERE urlhash='hashfrompreviousquery' LIMIT 1;
You'll have to remove duplicates more than once if you have >2 identical
urlhash entries. LIMIT -1 might do that for you. I'm not sure.
Default is now to take still thumbnails of animated GIFs and then
show them as originals in an AttachmentListItem. The still frames
are mostly used with front-ends like qvitter.
In some development code I noticed that when handling File objects without
filename values, there would be problems calling getPath and such.
The width and height value testing will be validated later anyway, and by
removing such a narrow test we can use events to generate thumbnails of
media formats supported by recently added plugins on demand.
We're now capable of doing image rotation for thumbnails based on
EXIF orientation data. Also, thumbnails are tracked by filenames and
thus we can delete them from storage when we feel like it.
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.
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.
I used this hacky sed-command (run it from your GNU Social root, or change the first grep's path to where it actually lies) to do a rough fix on all ::staticGet calls and rename them to ::getKV
sed -i -s -e '/DataObject::staticGet/I!s/::staticGet/::getKV/Ig' $(grep -R ::staticGet `pwd`/* | grep -v -e '^extlib' | grep -v DataObject:: |grep -v "function staticGet"|cut -d: -f1 |sort |uniq)
If you're applying this, remember to change the Managed_DataObject and Memcached_DataObject function definitions of staticGet to getKV!
This might of course take some getting used to, or modification fo StatusNet plugins, but the result is that all the static calls (to staticGet) are now properly made without breaking PHP Strict Standards. Standards are there to be followed (and they caused some very bad confusion when used with get_called_class)
Reasonably any plugin or code that tests for the definition of 'GNUSOCIAL' or similar will take this change into consideration.
The parent class for our database objects, Managed_DataObject, has a
dynamically assigned class in staticGet which objects get put into,
leaving us with less code to do the same thing.
We will probably have to move away from the DB_DataObject 'staticGet'
call as it is nowadays deprecated.
We've been muddling through with 6- or 8-argument functions for managing streams. I'd
like to start thinking of streams as their own thing, and give them some more value.
So, the new NoticeStream class takes over the Notice::stream() function and Notice::getStreamByIds().
There's probably some fine-tuning to do on the object interface.
* dropped unnecessary join on notice table
* made the function actually static, since it makes no sense as an instance variable. The only caller (in AttachmentList) is updated.
Pretty much everything in File and File_redirection initial processing needs to be rewritten to be non-awful; this code is very hard to follow and very easy to make huge bugs. A fair amount of the complication is probably obsoleted by the redirection following being built into HTTPClient now.
Also stripping id from foreign HTML messages (could interfere with UI) and disabled failing attachment popup for a.attachment links that don't have a proper id, so you can click through instead of getting an error.
Issues:
* any other links aren't marked and saved
* inconsistent behavior between local and remote attachments (local displays in lightbox, remote doesn't)
* if the enclosure'd object isn't referenced in the content, you won't be offered a link to it in our UI
