The target realm was not being passed to create_attachment in
upload_message_file implementations. This was a bug in the edge-case of
cross-realm messages - in particular, causing a bug in the email
gateway:
When an email with an attachment is sent, the message is mirrored to
Zulip with Email Gateway Bot as the message sender and uploader of the
attachment. Due to the realm not being passed to create_attachment, the
Attachment would get created with .realm being the system bot realm,
making the attachment inaccessible under some conditions due to failing
the following condition check (that's expected to pass, provided that
the .realm is set correctly):
```
if (
attachment.is_realm_public
and attachment.realm == user_profile.realm
and user_profile.can_access_public_streams()
):
# Any user in the realm can access realm-public files
return True
```
This also fixes a warning from
RealmExportTest.test_endpoint_local_uploads: “ResourceWarning:
unclosed file <_io.BufferedReader
name='/srv/zulip/var/…/test-export.tar.gz'>”.

We now complain if a test author sends a stream message
that does not result in the sender getting a
UserMessage row for the message.
This is basically 100% equivalent to complaining that
the author failed to subscribe the sender to the stream
as part of the test setup, as far as I can tell, so the
AssertionError instructs the author to subscribe the
sender to the stream.
We exempt bots from this check, although it is
plausible we should only exempt the system bots like
the notification bot.
I considered auto-subscribing the sender to the stream,
but that can be a little more expensive than the
current check, and we generally want test setup to be
explicit.
If there is some legitimate way than a subscribed human
sender can't get a UserMessage, then we probably want
an explicit test for that, or we may want to change the
backend to just write a UserMessage row in that
hypothetical situation.
For most tests, including almost all the ones fixed
here, the author just wants their test setup to
realistically reflect normal operation, and often devs
may not realize that Cordelia is not subscribed to
Denmark or not realize that Hamlet is not subscribed to
Scotland.
Some of us don't remember our Shakespeare from high
school, and our stream subscriptions don't even
necessarily reflect which countries the Bard placed his
characters in.
There may also be some legitimate use case where an
author wants to simulate sending a message to an
unsubscribed stream, but for those edge cases, they can
always set allow_unsubscribed_sender to True.
If realm is web_public, spectators can now view avatar of other
users.
There is a special exception we had to introduce in rest model to
allow `/avatar` type of urls for `anonymous` access, because they
don't have the /api/v1 prefix.
Fixes#19838.
It is confusing to have the plan type constants not be namespaced
by the thing they represent. We already have a namespacing
convention in place for constants, so we should use it for
Realm.plan_type as well.
Now, when we add a custom animated emoji to the realm
we also save a still image of it (1st frame of the gif). So
we can avoid showing an animated emoji every time.
This commit modifies the copy_user_settings code such that instead
of source user profile, we can have two types of sources - a user
profile and RealmUserDefault table of realm and then set the
settings from RealmUserDefault only is there is no user profile
as a source.
We also rename copy_user_settings to copy_default_settings for
clarity.
This causes avatars and emoji which are hosted by Zulip in S3 (or
compatible) servers to no longer go through camo. Routing these
requests through camo does not add any privacy benefit (as the request
logs there go to the Zulip admins regardless), and may break emoji
imported from Slack before 1bf385e35f,
which have `application/octet-stream` as their stored Content-Type.
`ensure_basic_avatar_image` and `ensure_medium_avatar_image` are
essentially the same thing, except a size parameter.
So, refactor them into a single function.
This doesn't introduce any functional changes.
Previously, S3UploadBackend.delete_export_tarball failed to strip the
leading ‘/’ from the export path. This mistake is now caught by Moto
1.3.15. I expect it caused deletion failures in the real S3, although
I haven’t verified this.
We store export_path in the audit log with a leading ‘/’, but the
actual S3 keys do not have a leading ‘/’. Changing either system
would require a migration. So the new convention is that the
variables named ‘export_path’ have a leading ‘/’, while variables
named ‘path_id’ or ‘key’ do not.

This commit adds the is_web_public field in the AbstractAttachment
class. This is useful when validating user access to the attachment,
as otherwise we would have to make a query in the db to check if
that attachment was sent in a message in a web-public stream or not.
The S3 data export tool's upload code path uses this nice boto
callback feature for showing a progress bar, which is nice for the
management command. It's spammy/broken in production and the backend
tests, so we change percent_callback to be a parameter passed in so
that it can only be used in the contexts where it makes sense.
Fixes#2665.

Note from tabbott: In a few cases, this converts technical debt in the

our largest files having very long, ugly import sequences at the

those files, which isn't a bad thing.

We try to use the correct variation of `email`
or `delivery_email`, even though in some
databases they are the same.
(To find the differences, I temporarily hacked
populate_db to use different values for email
and delivery_email, and reduced email visibility
in the zulip realm to admins only.)
In places where we want the "normal" realm
behavior of showing emails (and having `email`
be the same as `delivery_email`), we use
the new `reset_emails_in_zulip_realm` helper.
A couple random things:
- I fixed any error messages that were leaking
the wrong email
- a test that claimed to rely on the order
of emails no longer does (we sort user_ids
instead)
- we now use user_ids in some place where we used
to use emails
- for IRC mirrors I just punted and used
`reset_emails_in_zulip_realm` in most places
- for MIT-related tests, I didn't fix email
vs. delivery_email unless it was obvious
I also explicitly reset the realm to a "normal"
realm for a couple tests that I frankly just didn't
have the energy to debug. (Also, we do want some
coverage on the normal case, even though it is
"easier" for tests to pass if you mix up `email`
and `delivery_email`.)
In particular, I just reset data for the analytics
and corporate tests.
We now have this API...
If you really just need to log in
and not do anything with the actual
user:
self.login('hamlet')
If you're gonna use the user in the
rest of the test:
hamlet = self.example_user('hamlet')
self.login_user(hamlet)
If you are specifically testing
email/password logins (used only in 4 places):
self.login_by_email(email, password)
And for failures uses this (used twice):
self.assert_login_failure(email)
This reduces query counts in some cases, since
we no longer need to look up the user again. In
particular, it reduces some noise when we
count queries for O(N)-related tests.
The query count is usually reduced by 2 per
API call. We no longer need to look up Realm
and UserProfile. In most cases we are saving
these lookups for the whole tests, since we
usually already have the `user` objects for
other reasons. In a few places we are simply
moving where that query happens within the
test.
In some places I shorten names like `test_user`
or `user_profile` to just be `user`.
This commit mostly makes our tests less
noisy, since emails are no longer an important
detail of sending messages (they're not even
really used in the API).
It also sets us up to have more scrutiny
on delivery_email/email in the future
for things that actually matter. (This is
a prep commit for something along those
lines, kind of hard to explain the full
plan.)
In 3892a8afd8, we restructured the
system for managing uploaded files to a much cleaner model where we
just do parsing inside bugdown.
That new model had potentially buggy handling of cases around both
relative URLs and URLS starting with `realm.host`.
We address this by further rewriting the handling of attachments to
avoid regular expressions entirely, instead relying on urllib for
parsing, and having bugdown output `path_id` values, so that there's
no need for any conversions between formats outside bugdowm.
The check_attachment_reference_change function for processing message
updates is significantly simplified in the process.
The new check on the hostname has the side effect of requiring us to
fix some previously weird/buggy test data.

MigrationsTestCase is intentionally omitted from this, since migrations
tests are different in their nature and so whatever setUp()
ZulipTestCase may do in the future, MigrationsTestCase may not
necessarily want to replicate.
Apparently, our change in b8a1050fc4 to
stop caching responses on API endpoints accidentally ended up
affecting uploaded files as well.
Fix this by explicitly setting a Cache-Control header in our Sendfile
responses, as well as changing our outer API caching code to only set
the never cache headers if the view function didn't explicitly specify
them itself.
This is not directly related to #13088, as that is a similar issue
with the S3 backend.
Thanks to Gert Burger for the report.
The original seems to be unmaintained
(johnsensible/django-sendfile#65). Notably, this fixes a bug in the

The conditional block containing the tarball upload logic for both S3
and local uploads was deconstructed and moved to the more appropriate
location within `zerver/lib/upload.py`.
This is useful when syncing avatars from an integrated LDAP/active
directory.
The upload avatar and delete avatar buttons are hidden if avatar
changes are disabled and the user is a non-admin.
If the user has a gravatar set, then the user will not be able to
upload an image as their avatar if avatar changes are disabled.
Part of #12132.
This reverts commit fd9dd51d16 (#1815).

This renames references to user avatars, bot avatars, or organization
icons to profile pictures. The string in the UI are updated,
in addition to the help files, comments, and documentation. Actual

Fixes#11824.
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 make it easily for mobile/terminal apps to handle
situations like the user's API key changing.
Also fix the fact we were incorrectly using a 400, not 401, status
code for this case.
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.
Now reading API keys from a user is done with the get_api_key wrapper
method, rather than directly fetching it from the user object.
Also, every place where an action should be done for each API key is now
using get_all_api_keys. This method returns for the moment a single-item
list, containing the specified user's API key.
This commit is the first step towards allowing users have multiple API
keys.
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.

'\\[[X| ]\\] (\\d+_.+)\n' ↦ '\\[[X| ]\\] (\\d+_.+)\\n'
which is fine because re treats '\\x1b' and '\\n' the same way as
'\x1b' and '\n'.

This fixes two issues:
* Our guest users feature gave guest users access to public stream
attachments even if they couldn't access the public stream.
* After a user joins a private stream with our new shared history
feature, they couldn't see images uploaded before they joined.
The tests need to check for a few types of issues:
* The actual access control permissions.
* How many database queries are used in the various
cases for that second model, especially with multiple messages
referencing an attachment. This function gets called a lot, and we
want to keep it fast.
Fixes#9372.
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.
This extends the /user_uploads API endpoint to support passing the
authentication credentials via the URL, not the HTTP_AUTHORIZATION
headers. This is an important workaround for the fact that React
Native's Webview system doesn't support setting HTTP_AUTHORIZATION;
the app will be responsible for rewriting URLs for uploaded files
directly to add this parameter.
We start to force downloads for the attachment files. We do this
for all files except images or pdf's. We would like images or pdf's
to open up in browser itself.
Tweaked by tabbott for comment clarity and correctness.
From here on we start to authenticate uploaded file request before
serving this files in production. This involves allowing NGINX to
pass on these file requests to Django for authentication and then
serve these files by making use on internal redirect requests having
x-accel-redirect field. The redirection on requests and loading
of x-accel-redirect param is handled by django-sendfile.
NOTE: This commit starts to authenticate these requests for Zulip
servers running platforms either Ubuntu Xenial (16.04) or above.
Fixes: #320 and #291 partially.
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).
This function is designed to replace avatar_url() and
avatar_url_from_dict() over time.
There are a few things new about it:
* We make the parameters more explicit, rather than
passing in an opaque dictionary or requiring a
UserProfile object. (A lot of our callers want
to use `values()` for efficiency sake, since we
are often doing bulk user operations.)
* We start to support the client_gravatar option.
