As we have seen no further cases of this in production since #23215,
increase the severity to an error, and switch from returning a
list (which is not type-safe if the function declares a QuerySet
return) to returning the QuerySet without caching.
Failing to store the result in the cache, with an error, seems
superior to raising an exception; in both cases the next request will
redo the work, but we are guaranteed a worse user experience if we 500
the request.

Prior to 53231aa, the `ignore_unhashable_lru_cache` decorator had
a check for the development environment so that changes could be

Puts that check back in IgnoreUnhashableLruCacheWrapper class.
In the outgoing webhook handler, there is potentially several seconds
of trying between when a message triggering an outgoing webhook
arrives, and when it fails. In the meantime, the stream the
triggering message was on may have been deleted, causing the
"Failure!" message to have no valid stream to be sent to.
Rather than raise an exception in the outgoing webhook worker, ignore
the exception and move on.
The lambda passed to `queue_json_publish` is used if
`settings.USING_RABBITMQ` is unset -- which is only true in tests. As
such, this pattern causes failures to never actually retry within
tests.
This behaviour has existed ever since the outgoing webhook code was
introduced in 53a8b2ac87, with no explanation. Not passing that
argument allows tests to verify the retry behaviour when webhooks
fail.
Previously, test cases or clients accessing /json/ views using HTTP
Basic Auth would be accepted, while we intended to only allow clients
authenticated with a session cookie to access these views.
This adds a check on the accessed path to avoid this possibility.
It seems unlikely that any API clients clients were taking advantage
of this unintended quirk; so we're not going to bother documenting
this bug fix as an API change. In any case, it should be trivial for
anyone affected to consult the documentation and then switch their
/json/foo URL to a correct /api/v1/foo URL.

Mobile clients older than v27.192 do not support PRONOUNS type
custom profile fields, so we instead change the type of it to
SHORT_TEXT in the data sent with register response and also in
the events sent to those clients.
On multi-realm systems this results in traversal of all messages in
all realms and returns a massive payload of 1 row per stream on
the server, not the intended one row per realm.
This guarantees that the Realm is always non-None when we hit the
codepath is_static_or_current_realm_url via
do_change_stream_description, so that we can properly skip rewritting
some images.

This commit updates the urls for personal narrow sent in email

webapp by replacing the url characters encoded by browser with "-".
Updates the hash used for the recent conversations view to be
"#recent" instead of "#recent_topics".
We will need to keep the logic for handling "#recent_topics"
permanently because users potentially have messages from
Welcome Bot with links to that hash.

On my data (about 10 million messages in 1600 streams) this used to take
about 40 hours, while the improved statement completes in roughly 30
seconds.
The old solution had postgres go through the entire table until the
first match for each stream. Thus, the time spent scanning the table
got longer and longer for each stream because postgres always started at
the beginning (and somehow it did not use any indices) and had to skip
over all rows until it found the first message from the stream that is
was looking for each time.
This new statement just performans a bulk operation, scanning the table
only once and then inserts the results directly into the destination
table.

Send an empty list of `custom_profile_fields` in `page_params` for
spectators, rather than not sending the field at all.
Also, updates the user info popover to not show the manage user
three-dot menu when in a spectator view.
As noted in the previous commit, this causes bloat in memcached, for

Storing this key is superfluous, as it will be the same for all users,
and definitionally already known to fetch the cache for the realm. It
is also not currently used by the callsites that read rows from the

Previously, we included all three message edit related settings
("allow_message_editing", "message_content_edit_limit_seconds" and
"edit_topic_policy") in the event data and api response irrespective
of which of these settings were changed. Now, we only include changed
settings and separate events are sent for each setting if more than
one of them is changed.
Note that the previous typed in event_schema.py for
`message_content_edit_limit_seconds` incorrectly did not allow `None`
as a value, which is used to encode no limit.
This refactors and renames user_ids_muting_topic to accept a parameter
'visibility_policy' and fetch user IDs that have a specific
visibility_policy(provided as the parameter) set for a topic.
Unfortunately, doing so requires forking common API documentation
text, since we're not making any changes to other endpoints that don't
allow unauthenticated requests at all.

SCIMClient is a type-unsafe workaround for django-scim2’s conflation
of SCIM users with Django users. Given that a SCIMClient is not a
UserProfile, it might as well not be a model at all, since it’s only
used to satisfy django-scim2’s request.user.is_authenticated queries.
This doesn’t solve the type safety issue with assigning a SCIMClient
to request.user, nor the performance issue with running the SCIM
middleware on non-SCIM requests. But it reduces the risk of potential
consequences worse than crashing, since there’s no longer a
request.user.id for Django to confuse with the ID of an actual
UserProfile.

Previously, an active production Zulip server would experience a class
of deadlocks caused by two or more concurrent bulk update operations
on the UserMessage table.
This is because UPDATE ... SET ... WHERE statements that execute in
parallel take row-level UPDATE locks as they get results; since the
query plans may result in getting rows in different orders between two
queries, this can result in deadlocks.
Some databases allow ORDER BY on their UPDATE ... WHERE statements;
PostgreSQL does not. In PostgreSQL, the answer is to do a sub-select
with an ORDER BY ... FOR UPDATE to ensure consistent ordering on row
locks.
We do this all code paths using bitand or bitor as part of bulk
editing message flags, which should ensure that these concurrent
operations obtain row level locks on the table in the same order.

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

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
