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 previous code for ensuring the sort order of emoji choices was
correct relied on an OrderedDict structure, which isn't guaranteed to
be preserved when passed to the frontend via JSON (in fact, it isn't,
since we converted the way page_params is passed to use
sort_keys=True). Switch it to a list of dictionaries to correct this.
Fixes#13220.
Previously, we were hardcoding the domain s3.amazonaws.com. Given
that we already have an interface for configuring the host in
/etc/zulip/boto.cfg (which in turn, automatically configures boto), we
just need to actually use the value configured in boto for what S3
hostname to use.
We don't have tests for this new use case, in part because they're
likely annoying to write with `moto` and there hasn't been a huge
amount of demand for it. Since this doesn't regress existing S3
backend support, it seems worth merging.
This patches an issue in f37535044 where we mistakenly tried to send
the function as part of the page_params. Instead, we should just try
to send the list of configuration options (in their user displayable
form).
This change adds the OpenAPI data needed to document the POST and
DELETE methods associated with this endpoint.
Descriptions edited slightly by tabbott.
Apparently, the Zulip notifications (and resulting emails) were
correct, but the download links inside the Zulip UI were incorrectly
not including S3 prefix on the URL, making them not work.
While we're at this, we rewrite the somewhat convoluted previous
system for formatting the data export output.
When using our EMAIL_ADDRESS_VISIBILITY_ADMINS feature, we were
apparently creating bot users with different email and delivery_email
properties, due to effectively an oversight in how the code was
written (the initial migration handled bots correctly, but not bots
created after the transition).
Following the refactor in the last commit, the fix for this is just
adding the missing conditional, a test, and a database migration to
fix any incorrectly created bots leaked previously.
This is also a useful preparatory refactor for having a user setting
controlling whether one's own email address is publicly available
within the organization.
This should dramatically improve the queue processor's performance in
cases where there's a very high volume of requests on a given endpoint
by a given user, as described in the new docstring.
Until we test this more broadly in production, we won't know if this
is a full solution to the problem, but I think it's likely. We've
never seen the UserActivityInterval worker end up backlogged without a
total queue processor outage, and it should have a similar workload.
Fixes#13180.
We don't actually need to go to the memcached (falling back to the
database) to fetch either user or client objects on every event. For
user objects, we actually can just pass through the user ID
transparently; for client objects, we can use an in-process cache,
since the mapping of string to ID never changes.
With the way these tests are, it's unnecessary to have 3 separate
classes, and it makes it confusing to decide where to add a potential
additional mm email test.
This simple backwards-compatible change saves approximately 12% in the
compressed size of the chat.zulip.org page_params. We can do much,
much better by changing the format, but this seems like a good
intermediate step.

In a gigantic realm where we send several MB of `page_params`, it’s
slightly better to have the rest of the `<body>` available to the
browser earlier, so it can show the “Loading…” spinner and start
fetching subresources.

any_oauth_backend_enabled is all about whether we will have extra
buttons on the login/register pages for logging in with some non-native
backends (like Github, Google etc.). And this isn't about specifically
oauth backends, but generally "social" backends - that may not rely
specifically rely on Oauth. This will have more concrete relevance when
SAML authentication is added - which will be a "social" backend,
requiring an additional button, but not Oauth-based.
This sidesteps tricky escaping issues, and will make it easier to
build a strict Content-Security-Policy.

Previously, incorrectly passing an existing directory to the
`manage.py export --output` option would remove its contents without
warning. Abort instead.

* Whitelist a small number of image/ types to be served as
non-attachments.
* Serve the file using the type that we validated rather than relying
on an independent guess to match.
This issue can lead to a stored XSS security vulnerability for older
browsers that don't support Content-Security-Policy.
It primarily affects servers using Zulip's local file uploads backend
for servers running Ubuntu 16.04 Xenial or newer; the legacy local
file upload backend for (now EOL) Ubuntu 14.04 Trusty was not affected
and it has limited impact for the S3 upload backend (which uses an
unprivileged S3 bucket domain to serve files).

This brings us in line, and also allows us to style these more like
unordered lists, which is visually more appealing.
On the backend, we now use the default list blockprocessor + sane list
extension of python-markdown to get proper list markup; on the
frontend, we mostly return to upstream's code as they have followed
CommonMark on this issue.
Using <ol> here necessarily removes the behaviour of not renumbering
on lists written like 3, 4, 7; hopefully users will be OK with the
change.
Fixes#12822.
