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.
Based in part on work by Vishnu Ks (hackerkid).
All JsonableError subclasses now have corresponding ErrorCode values
of their own, reducing the number of different patterns for using
the new JsonableError API.
- Add file_name field to `RealmEmoji` model and migration.
- Add emoji upload supporting to Upload backends.
- Add uploaded file processing to emoji views.
- Use emoji source url as based for display url.
- Change emoji form for image uploading.
- Fix back-end tests.
- Fix front-end tests.
- Add tests for emoji uploading.
Fixes#1134
The previous logic was that anyone with a link to a file could send it
to other users, but only the owner could make a file realm-public.
This had some confusing corner cases.
The new logic is much simpler:
* Only the file's owner/uploader can include a file in a message for
the first time.
* Anyone with access to read a file can share it with others by
including it in messages they send.
* Once a file has been sent to a public stream, any user in the realm
can access it.
In this commit we change user_avatar_hash with user_avatar_path which
now returns paths to avatars based on the email hash.
Tweaked by tabbott to avoid an import loop.
In this commit we just change the upload_avatar_image function to accept
two user_profiles acting_user_profile and target_user_profile. Basically
email param is dropped for a target_user_profile so that avatar's could
be moved lateron to user id based storage.
