Without this change, pyflakes reports this exception:
pyflakes | zerver/worker/queue_processors.py:152:9 local variable 'e' is assigned to but never used
pyflakes | zerver/worker/queue_processors.py:155:81 undefined name 'e'
We use the EMAIL_TIMEOUT django setting to timeout after 15s of trying
to send an email. This will nicely lead to retries in the email_senders
queue, due to the retry_send_email_failures decorator.
smtlib documentation suggests that socket.timeout can be raised as the
result of timing out, so in attempts I'm getting
smtplib.SMTPServerDisconnected. Either way, seems appropriate to add
socket.timeout to the exception that we catch.
This fixes our triggering a RabbitMQ event to send a push notification
to remove the empty set of push notifications, resulting from not
using the correct data structure to determine which message IDs to look at.
This was causing a lot of visible exceptions when running
the `test_messages.py` test suite.
For users who are unsubscribed from the new stream but are in
the old stream, we delete the UserMessage.
We send the delete_message event only to guest users,
who have completely lost asses to the moved messages, for other
users we send the normal update_message event which moves
the messages to the new unsubed stream which
otherwise would look broken to the
user without reloading to the webpage.
Our previous OpenAPI schema validator that we implemented ourselves
was useful training wheels for our understanding OpenAPI properly, and
was mostly correct. But given that we've finally reached the point
where our OpenAPI file accurately describes the API, it makes sense to
switch to use an official OpenAPI validator. We lose some ability to
do exclude rules for particular elements, but those were primarily
important for us when we had a lot of them.
As part of this change, we need to add `additionalProperties: false`
for all of our dictonaries/objects where we've documented every
parameter; otherwise the OpenAPI schema checker won't know that we
expect every parameter to be documented.
This was hiding an actual type error in test_cache: a mismatch between
the object ID type, which is str, and the default id_fetcher, which
returns int.
Mypy’s insufficient support for default generic arguments basically
means we can’t use them without a lot of overloading, and there are
not enough callers here to justify that.

We avoid this being super messy where the code calls this by adding
some less generic wrappers for generic_bulk_cached_fetch.
