This additional logic to prevent resizing is certain circumstances
(file size, dimensions) is necessary because the pillow gif handling
code seems to be rather flaky with regards to handling gif color
palletes, causing broken gifs after resizing. The workaround is to
only resize when absolutely necessary (e.g. because the file is larger
than 128x128 or 128KB).
Fixes#10351.
This should hopefully be the last commit of this form; ultimately, my
hope is that we'll be able to refactor the semi-duplicated logic in
this file to avoid so much effort going into keeping this correct.
Our HipChat conversion tool didn't properly handle basic avatar
images, resulting in only the medium-size avatar images being imported
properly. This fixes that bug by asking the import tool to do the
thumbnailing for the basic avatar image (from the .original file) as
well as the medium avatar image.
This adds a new realm_logo field, which is a horizontal-format logo to
be displayed in the top-left corner of the webapp, and any other
places where we might want a wide-format branding of the organization.
Tweaked significantly by tabbott to rebase, fix styling, etc.
Fixing the styling of this feature's loading indicator caused me to
notice the loading indicator for the realm_icon feature was also ugly,
so I fixed that too.
Fixes#7995.
This commit adds 'resize_gif()' function which extracts each frame,
resize it and coalesces them again to form the resized GIF while
preserving the duration of the GIF. I read some stackoverflow
answers all of which were referring to BiggleZX's script
(https://gist.github.com/BigglesZX/4016539) for working with animated
GIF. I modified the script to fit to our usecase and did some manual
testing but the function was failing for some specific GIFs and was not
preserving the duration of animation. So I went ahead and read about
GIF format itself as well as PIL's `GifImagePlugin` code and came up
with this simple function which gets the worked done in a much cleaner
way. I tested this function on a number of GIF images from giphy.com
and it resized all of them correctly.
Fixes: #9945.
The only changes visible at the AST level, checked using
https://github.com/asottile/astpretty, are
zerver/lib/test_fixtures.py:
'\x1b\\[(1|0)m' ↦ '\\x1b\\[(1|0)m'
'\\[[X| ]\\] (\\d+_.+)\n' ↦ '\\[[X| ]\\] (\\d+_.+)\\n'
which is fine because re treats '\\x1b' and '\\n' the same way as
'\x1b' and '\n'.

Fixes the avatar/emoji part of #8177.
Does not address the issue with uploaded images, since we don't do
anything with them.
Also adds 3 images with different orientation exif tags to
test-images.
We send add events on upload, update events when sending a message
referencing it, and delete updates on removal.
This should make it possible to do real-time sync for the attachments
UI.
Based in part on work by Aastha Gupta.
We'll replace this primarily with per-realm quotas (plus the simple
per-file limit of settings.MAX_FILE_UPLOAD_SIZE, 25 MiB by default).
We do want per-user quotas too, but they'll need some more management
apparatus around them so an admin has a practical way to set them
differently for different users. And the error handling in this
existing code is rather confused. Just clear this feature out
entirely for now; then we'll build the per-realm version more cleanly,
and then we can later add back per-realm quotas modelled after that.
The migration to actually remove the field is in a subsequent commit.
