This commit strengthens types by typing the webhook's incoming
payload as WildValue, which eradicates the use of Any within the
Zabbix incoming webhook integration.
The KeyError exception has been replaced to catch a ValidationError
instead now, since the incoming payload's keys will be tamed before
usage and the non-existence of the key is raised as a
ValidationError in the taming function.
Extends the URL redirect system used for documentation pages to corporate
landing pages. This makes it easier and consistent for contributors who
work on both areas to create new URL redirects when needed.
Creates `zerver.lib.url_redirects.py` to record old and new URLs
for documentation pages that have been renamed/moved and need URL
redirects.
This file is then used by `zproject.urls.py` to redirect links and
by `zerver.test.test_urls.py` to test that all of the old URLs
return a success response with a common page header/text depending
on the type of redirect (help center, policy, or API).
Adds a section to contributor docs on writing documentation for
how to use this redirect system when renaming a help center or api
documentation page.

django.request logs responses with 5xx response codes (our configuration
of the logger prevents it from logging 4xx as well which it normally
does too). However, it does it without the traceback which results in
quite unhelpful log message that look like
"Bad Gateway:/api/v1/users/me/apns_device_token" - particularly
confusing when sent via email to server admins.
The solution here is to do the logging ourselves, using Django's
log_response() (which is meant for this purpose), and including the
traceback. Django tracks (via response._has_been_logged attribute) that
the response has already been logged, and knows to not duplicate that
action. See log_response() in django's codebase for these details.
Fixes#19596.
It seems helpful for this to get logged with the traceback rather than

Only ["id"] is accessed on the dicts (representing the external tool

We add quote prefix ">" to each line of the message in the plain text
missed message emails, which are then rendered as quotes by email

This commit checks for null values for keys within "attachment" in
the Slack integration's incoming payloads. These keys were expected
to exist optionally previously, and the existence of null values for
these wasn't anticipated. Due to an issue report for such null
values in the payload, their handling is updated appropriately.
The checks for these values are truthiness checks since the strategy
for these values being null or falsy ("", 0) is the same; we don't
process that key-value pair. This is consistent with how Slack handles
this scenario.
For the case where all the attachment fields have null values, Slack
displays this as an empty block with no content, and therefore our
strategy for this is a no-op.

This will have no real effect in most situations. However, a user
moves a topic to another stream while also adding/removing the
resolved-topic checkmark from the topic name, then the "This topic was
resolved" notificaiton will now appear just before the "This topic was
moved" notification rather than just after.
This is likely slightly less confusing to users, since the topic
having been moved from somewhere else is likely the most salient fact
to a reader.
We expect to change things to not send both notifications in an
upcoming commit.
This refactoring helps with #21712.
Our seat count calculation is different for guest user than normal users
(a number of initial guests are free, and additional marginal guests are

being added.

This change incorporate should_rate_limit into rate_limit_user and

to rate_limit_request_by_ip is made as we now check if the client is
eligible to be exempted from rate limiting now, which was previously
only done as a part of zerver.lib.rate_limiter.rate_limit.
Now we mock zerver.lib.rate_limiter.RateLimitedUser instead of
zerver.decorator.rate_limit_user in
zerver.tests.test_decorators.RateLimitTestCase, because rate_limit_user
will always be called but rate limit only happens the should_rate_limit
check passes;
we can continue to mock zerver.lib.rate_limiter.rate_limit_ip, because the
decorated view functions call rate_limit_request_by_ip that calls
rate_limit_ip when the should_rate_limit check passes.
We need to mock zerver.decorator.rate_limit_user for SkipRateLimitingTest
now because rate_limit has been removed. We don't need to mock
RateLimitedUser in this case because we are only verifying that
the skip_rate_limiting flag works.

There may be some internal realms which were created after applying

respective system groups. And due to this change, now bots in
development environment are also added to system groups.
Tests are changed accordingly as more UserGroupMembeship objects
are created.
Since we include internal realms while creating system groups

I found the previous model for computing what settings to use for
streams increasingly difficult to understand, which is generally a
recipe for future bugs.
Refactor to have a clear computation of what complete permissions
state the client is requesting, validate that state, and then pass
that state to the do_change_stream_permission.
We now allow changing access to history of the stream by only passing
"history_public_to_subscribers" parameter. Previously, "is_private"
parameter was also required to change history_public_to_subscribers
otherwise the request was silently ignored.
We also raise error when only history_public_to_subscribers parameter
is passed with value False without "is_private: True" for a public
or web-public stream since we do not allow public streams with
protected history.
We raise error when we try to change a public stream (except for
zephyr mirror realms) to be public with protected history, as we do
not support such streams yet.
Previously, in such case we changed nothing and a notification was
sent to the "stream events" topic with message being "stream is
changed from public to public" and was weird.
Note that this commit only handles the case when both is_private and
history_public_to_subscribers parameters are passed to API and commit
not covers the case when only "history_public_to_subscribers" with
value False is passed to API, since we currently ignore requests
which has only history_public_to_subscribers parameter with not None
and not is_private and is_web_public.
We would do this in further commits when we add support for accepting
only history_public_to_subscribers parameter.
This commit removes the unnecessary assertion statements in
do_change_stream_permission for case when "is_web_public" is
True, since we already check those cases in the view function
update_stream_backend and this is the only place from where
do_change_stream_permission is called.
We aim to remove other assertions also from there as mentioned
in the comment and instead check the values in caller itself.
This is a prep commit for changing do_change_stream_permission
to require passing all (invite_only, history_public_to_subscribers
and is_web_public) arguments in further commits.

It is apparently possible to have a mention of a user who is not (or
no longer?) in the `users.bson` table.
Skip such mention for the purposes of Zulip import; there's nothing
better for us to do.
This is likely an error somewhere in rocketchat's MongoDB "eventual
consistency," but there is no problem with skipping the chunks at this
step.
In the one case where this was observed so far, the upload-id was not
referenced in any message -- if it is referenced and has chunks, but
has no metadata, we will fail later, at that reference.
This `mimetype` parameter was introduced in c4fa29a and its last
usage removed in 5bab2a3. This parameter was undocumented in the
OpenAPI endpoint documentation for `/user_uploads`, therefore
there shouldn't be client implementations that rely on it's
presence.
Removes the `request.GET` call for the `mimetype` parameter and
replaces it by getting the `content_type` value from the file,
which is an instance of Django's `UploadedFile` class and stores
that file metadata as a property.
If that returns `None` or an empty string, then we try to guess
the `content_type` from the filename, which is the same as the
previous behaviour when `mimetype` was `None` (which we assume
has been true since it's usage was removed; see above).
If unable to guess the `content_type` from the filename, we now
fallback to "application/octet-stream", instead of an empty string
or `None` value.
Also, removes the specific test written for having `mimetype` as
a url parameter in the request, and replaces it with a test that
covers when we try to guess `content_type` from the filename.
Updates `json_change_settings` so that the default value for the `email`,
`full_name`, `new_password` and `old_password` parameters is `None` instead
of an empty string, which also makes the type annotation `Optional[str]`.
Also, updates tests for email and full name changes to include an empty
string as one of the tested invalid values.
Because Django's ContentType objects are, by default, created lazily
when an actual object is created that will use them, this migration
would fail on any server that actually had RealmReactivationStatus
objects already, and had not yet created the ContentType for them.
ContentType objects are very simple:
zulip=> select * from django_content_type where model = 'realmreactivationstatus';
id | app_label | model
----+-----------+-------------------------
85 | zerver | realmreactivationstatus
So we can simply patch this by using get_or_create.

This makes `has_request_variables` more generic, in the sense of the return
value, and also makes it more accurate, in the sense of requiring the
first parameter of the decorated function to be `HttpRequest`, and
preserving the function signature without using `cast`.
This affects some callers of `has_request_variables` or the callers of its
decoratedfunctions in the following manners:
- Decorated non-view functions called directly in other functions cannot
use `request` as a keyword argument. Becasue `Concatenate` turns the
concatenated parameters (`request: HttpRequest` in this case) into
positional-only parameters. Callers of `get_chart_data` are thus
refactored.
- Functions to be decorated that accept variadic keyword arguments must
define `request: HttpRequest` as positional-only. Mypy in strict mode
rejects such functions otherwise because it is possible for the caller to
pass a keyword argument that has the same name as `request` for `**kwargs`.
No defining `request: HttpRequest` as positional-only breaks type safety
because function with positional-or-keyword parameters cannot be considered
a subtype of a function with the same parameters in which some of them are
positional-only.
Consider `f(x: int, /, **kwargs: object) -> int` and `g(x: int,
**kwargs: object) -> int`. `f(12, x="asd")` is valid but `g(12, x="asd")`
is not.

This adds an assertion ensuring the type of `store` before accessing the
`cache_key` attribute that does not exist in the base class. Also note
that `.decode` returns `Dict[str, Any]` instead of a `str`.
