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 fix the occasionally breaking tests for
test_home.HomeTest.test_bad_narrow which were the result of
us patching global settings in test_upload to add some new emails
to CROSS_REALM_BOT_EMAILS and not rolling back.
This is a remerge of e985b57259 (after
resolving merge conflicts, updating the tests, adding mypy annotations
etc.), which should now be correct, because we've done the necessary
database migration.
The rebase/remerge work was done by Tim Abbott and Aditya Bansal.
This is an important part of #320.
- Add settings parameter for max realm icon size.
- Add settings parameter for max user avatar size.
- Add checking file size to avatar and icon
uploading views.
- Transfer file size limit parameter to frontend.
- Add tests.
In some cases here we simplify things by calling avatar_url()
instead of get_avatar_url(), when we have a user_profile record
handy. For other cases we pass in an extra avatar_version
parameter to get_avatar_url(), including from avatar_url().
We have a field called user_profile.avatar_version that will
track avatar versions and be used tactically in avatar urls
to get browsers to refresh their caches (in future commits).
This commit bumps the avatar version when we update avatars.
We do this in do_change_avatar_fields(), which was
do_change_avatar_source() before this change.
Adarsh did the initial work here, and Steve Howell (showell) also
made changes.
Add test about avatar image was uploaded properly or not in
`tests.BotTest.test_add_bot_with_user_avatar` and
`tests.BotTest.test_patch_bot_avatar`.
Add `get_test_image_file()` and `avatar_disk_path()` in
`zerver.lib.test_helpers` and deduplicate some codes.
Fixes#1276.
This adds a medium (500px) size avatar thumbnail, that can be
referenced as `{name}-medium.png`. It is intended to be used on the
user's own settings page, though we may come up with other use cases
for high-resolution avatars in the future.
This will automatically generate and upload the medium avatar images
when a new avatar original is uploaded, and contains a migration
(contributed by Kirill Kanakhin) to ensure all pre-existing avatar
images have a medium avatar.
Note that this implementation does not provide an endpoint for
fetching the medium-size avatar for another user.

This is some of the code we'd need if we wanted to have Zulip generate
avatars for things. Since it is so little useful code, and it's not
clear we will need this feature ever, we can remove this code to make
the codebase less confusing. It'd be easy to dig this out of history
if we ever want it.
Fixes#2101.
This makes us more consistent, since we have other wrappers
like client_patch, client_put, and client_delete.
Wrapping also will facilitate instrumentation of our posting code.
