Alex Vandiver a40b3e1118 realm_emoji: Stop swallowing all exceptions from upload_emoji_image.
Putting all of the logic in a `finally` block is equivalent to a bare
`except` block, which silently consumes all exceptions.

Move only the most-necessary parts into the except; this lets
`BadImageError` exceptions from `zerver/lib/upload.py` to escape,
allowing better the generic "Image file upload failed" to be replaced
with a more specific message.

It also allows unexpected exceptions, as the previous commit resolved,
to escape and 500.  This lets them be detected and resolved, rather
than give users a silently bad experience.

Alex Vandiver 96a5fa9d78 upload: Fix resizing non-animated images.
5dab6e9d31 began honoring the list of disposals for every frame.
Unfortunately, passing a list of disposals for a non-animated image
raises an exception:
```
  File "zerver/lib/upload.py", line 212, in resize_emoji
    image_data = resize_gif(im, size)
  File "zerver/lib/upload.py", line 165, in resize_gif
    frames[0].save(
  File "[...]/PIL/Image.py", line 2212, in save
    save_handler(self, fp, filename)
  File "[...]/PIL/GifImagePlugin.py", line 605, in _save
    _write_single_frame(im, fp, palette)
  File "[...]/PIL/GifImagePlugin.py", line 506, in _write_single_frame
    _write_local_header(fp, im, (0, 0), flags)
  File "[...]/PIL/GifImagePlugin.py", line 647, in _write_local_header
    disposal = int(im.encoderinfo.get("disposal", 0))
TypeError: int() argument must be a string, a bytes-like object or a
number, not 'list'
```

`check_add_realm_emoji` calls this as:

```
    try:
        is_animated = upload_emoji_image(image_file, emoji_file_name, a
uthor)
        emoji_uploaded_successfully = True
    finally:
        if not emoji_uploaded_successfully:
            realm_emoji.delete()
            return None
        # ...
```

This is equivalent to dropping _all_ exceptions silently.  As such,
Zulip has silently rejected all non-animated images larger than 64x64
since 5dab6e9d31.

Adjust to only pass a single disposal if there are no additional
frames.  Add a test for non-animated images, which requires also
fixing the incidental bug that all GIF images were being recorded as
animated, regardless of if they had more than 1 frame or not.

odunybrad 90aa45a316 emoji: Add database-level uniqueness constraint for RealmEmoji.
While races here are unlikely, it is most correct to enforce this
invariant at the database layer, and having a database-level

PIG208 495a8476be tests: Use assertion to enforce None-checks in tests.
This fixes a batch of mypy errors of the following format:

in the tests, adding assertions beforehand is justified presuming
that they oughtn't to be None.

sahil839 61acf68aa4 emoji: Allow emoji authors to delete the emoji always.
Previously, non-admin emoji authors were allowed to
delete the emoji only if add_emoji_by_admins_only
was false. But, as add_emoji_by_admins_only setting
is for who can add emoji and not delete emojis, it
should not affect the behavior of deleting emojis
and users should always be allowed to delete the
emojis which. they added themselves

aryanshridhar 7dc56fdcf2 settings_emoji: Allow only admins to override existing emojis.
Previously, even non-admins had the option to override built-in
emojis in the `Settings Emoji` UI.

This commits essentially limits the functionality of overriding
custom and allows only realm administrators to
override built-in emojis with their custom emojis by adding an
authorization check in the backend.

It also adds relevant tests in `test_realm_emoji` which tests
for the cases where an admin and non admin tries to override
the built-in emoji.

Fixes #18860.

Anders Kaseorg 463929f349 urls: Migrate re_path routes to path.
Django treats path("<name>") like re_path(r"(?P<name>[^/]+)") and
path("<path:name>") like re_path(r"(?P<name>.+)").

This is more readable and consistent than the mix of slightly
different regexes we had before, and fixes various bugs:

• The r'apps/(.*)$' regex was missing a start anchor ^, so it
  incorrectly matched all URLs that included apps/ as a substring
  anywhere.
• The r'accounts/login/(google)/$' regex was missing a start anchor ^,
  so it incorrectly matched all URLs that ended with
  accounts/login/google/.
• The type annotation of zerver.views.realm_export.delete_realm_export
  takes export_id as an int, but it was previously passed as a string.
• The type annotation of zerver.views.users.avatar takes medium as a
  bool, but it was previously passed as a string.
• The [0-9A-Za-z]+ pattern for uidb64 was missing the - and _
  characters that can validly be part of a base64url encoded
  string (although I think the id is actually a decimal integer here,
  in which case only 012345ADEIMNOQTUYcgjkwxyz are present in its
  base64url encoding).

Steve Howell c44500175d database: Remove short_name from UserProfile.
A few major themes here:

    - We remove short_name from UserProfile
      and add the appropriate migration.

    - We remove short_name from various
      cache-related lists of fields.

    - We allow import tools to continue to
      write short_name to their export files,
      and then we simply ignore the field
      at import time.

    - We change functions like do_create_user,
      create_user_profile, etc.

    - We keep short_name in the /json/bots
      API.  (It actually gets turned into
      an email.)

    - We don't modify our LDAP code much
      here.

Anders Kaseorg 365fe0b3d5 python: Sort imports with isort.
Fixes #2665.

Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.

Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start.  I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

There's no reason to send data beyond the user `id` of the uploader,
