Vishnu KS ae5bc92602 queue: Don't create confirmation objects twice during invite.
A confirmation object is already created when
do_send_confirmation_email is called just above.

Tweaked by tabbott to remove an unnecessary somewhat hacky database
query.

Tim Abbott 767a1b9f0c user_activity: Skip an unnecessary database query for new entries.
While new entries are an overwhelming minority of calls to this
function, it's still worth having a clean implementation.

Tim Abbott 1c73ce2450 user_activity: Use LoopQueueProcessingWorker strategy.
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.

Tim Abbott 52a2b2c6a8 tests: Move user_activity test next to slow_query test.

Wyatt Hoodes 92dd5e2c4f test_queue_worker: Remove timing from test_slow_queries_worker.
Testing a specific query time was causing spurious failures
in CI.

Wyatt Hoodes dc191b0be4 test_queue_worker: Test actual code path for slow_queries.
Instead of just mocking some fake events, we use the code
path that generates slow query events and publishes them
to SlowQueryWorker.

This test improvement would have got a recent potential regression
caught in code review.

Anders Kaseorg becef760bf cleanup: Delete leading newlines.
Previous cleanups (mostly the removals of Python __future__ imports)
were done in a way that introduced leading newlines.  Delete leading
newlines from all files, except static/assets/zulip-emoji/NOTICE,
which is a verbatim copy of the Apache 2.0 license.

Wyatt Hoodes 5686821150 middleware: Change write_log_line to publish as a dict.
We were seeing errors when pubishing typical events in the form of
`Dict[str, Any]` as the expected type to be a `Union`.  So we instead
change the only non-dictionary call, to pass a dict instead of `str`.

This is low priority, but it's nice to be consistently using the best

Mateusz Mandera c1ceba9037 rate_limiter: Move email_mirror limiter to use rate_limit_entity.
We change the rate limiting code in the email mirror to use the new,
general rate_limit_entity function.

Mateusz Mandera e32c444ecf email_mirror: Move some helper functions out of actions.py.
These functions don't really belong in actions.py, so we move them out,
into email_mirror_helpers.py. They can't go directly into
email_mirror.py or we'd get circular imports resulting in ImportError.

Mateusz Mandera 1901775383 email_mirror: Add realm-based rate limiting.
Closes #2420

We add rate limiting (max X emails withing Y seconds per realm) to the
email mirror. By creating RateLimitedRealmMirror class, inheriting from
RateLimitedObject, and rate_limit_mirror_by_realm function, following a
mechanism used by rate_limit_user, we're able to have this
implementation mostly rely on the already existing, and proven over
time, rate_limiter.py code. The rules are configurable in settings.py in
RATE_LIMITING_MIRROR_REALM_RULES, analogically to RATE_LIMITING_RULES.

Rate limit verification happens in the MirrorWorker in
queue_processors.py. We don't rate limit missed message emails, as due
to using one time addresses, they're not a spam threat.

test_mirror_worker is adapted to the altered MirrorWorker code and a new
test - test_mirror_worker_rate_limiting is added in test_queue_worker.py
to provide coverage for these changes.

Mateusz Mandera 386813f42b test_queue_worker: Clean up test_mirror_worker.
We clean up test_mirror_worker for more readability, as well as make it
verify that mirror_email gets called the correct amount of times and use
a correct rcpt_to address, so that the test doesn't fail when some
verification of the address is added in the following commits
implementing rate limiting in the email mirror.

Tim Abbott 50dc317466 notifications: Rename notifications.py to email_notifications.py.
This library is entirely about email notifications specifically, and
this rename should help make the codebase more readable.

Raymond Akornor 92dc3637df send_email: Add support for multiple recipients.
This adds a function that sends provided email to all administrators
of a realm, but in a single email. As a result, send_email now takes
arguments to_user_ids and to_emails instead of to_user_id and
to_email.

We adjust other APIs to match, but note that send_future_email does
not yet support the multiple recipients model for good reasons.

Tweaked by tabbott to modify `manage.py deliver_email` to handle
backwards-compatibily for any ScheduledEmail objects already in the
database.

Fixes #10896.

Tim Abbott 5cec566cb9 queue_processors: Rewrite MissedMessageWorker to always wait.
Previously, MissedMessageWorker used a batching strategy of just
grabbing all the events from the last 2 minutes, and then sending them
off as emails.  This suffered from the problem that you had a random
time, between 0s and 120s, to edit your message before it would be
sent out via an email.

Additionally, this made the queue had to monitor, because it was
expected to pile up large numbers of events, even if everything was
fine.

We fix this by batching together the events using a timer; the queue
processor itself just tracks the items, and then a timer-handler
process takes care of ensuring that the emails get sent at least 120s
(and at most 130s) after the first triggering message was sent in Zulip.

This introduces a new unpleasant bug, namely that when we restart a
Zulip server, we can now lose some missed_message email events;
further work is required on this point.

Fixes #6839.

Tim Abbott b0c393cf97 notifications: Format missed_messages argument as a dict.
Because in upcoming commits, we'll want to pass additional per-message
data into do_send_missedmessage_events_reply_in_zulip, we need to
expand the format for how we represent messages to account for that.

Tim Abbott c2ceb3c13b EmailSendingWorker: Fix retry for sending emails.
If an exception was thrown inside `send_email` resulting in a retry,
we would include the `failed_tries` data in the event, which turned
out to thrown an exception itself.

This fixes that flow, including deepening the test so that it would
fail if we didn't have the new logic.

Umair Khan 68513952fb email-worker: Create EmailSendingWorker.
This commit just copies all the code from MissedMessageSendingWorker
class to a new EmailSendingWorker class. All the logic to send an email
through a queue was already there. This commit only makes the logic
generic. It does so by creating a special purpose queue called
'email_senders' to send any type of email. To make
MissedMessageSendingWorker still work we derive it from
EmailSendingWorker. All the tests that were testing
MissedMessageSendingWorker now run against EmailSendingWorker.

Rishi Gupta 968aae167b invitations: Remove get_prereg_user_by_email.
The original logic is buggy now that emails can belong to (and be
invited to) multiple realms.

The new logic in the `invites` queue worker also avoids the bug where
when the PreregistrationUser was gone by the time the queue worker got
to the invite (e.g., because it'd been revoked), we threw an exception.

[greg: fix upgrade-compatibility logic; add test; explain
revoked-invite race above]

Steve Howell dbcc76b996 Fix MissedMessageWorker.
This fixes a regression in 25c669df52.

We were draining the queue in both the superclass and the subclass,
so by the time the subclass started processing events, there were
no events to process.  Now the subclass properly uses the events
passed in from the superclass.

Steve Howell 942db9b6c5 tests: Added ZulipTestCase.example_user() function.
The example_user() function is specifically designed for
AARON, hamlet, cordelia, and friends, and it allows a concise
way of using their built-in user profiles. Eventually, the
widespread use of example_user() should help us with refactorings
such as moving the tests users out of the "zulip.com" realm
and deprecating get_user_profile_by_email.
