Mateusz Mandera 9b50c49ea7 streams: Mark all messages as read when deactivating a stream.
The query to finds and marks all unread UserMessages in the stream as read
can be quite expensive, so we'll move that work to the deferred_work
queue and split it into batches.

Fixes #15770.

Mateusz Mandera 06151672ba
queue: Use locking to avoid race conditions in missedmessage_emails.
This queue had a race condition with creation of another Timer while
maybe_send_batched_emails is still doing its work, which may cause
two or more threads to be running maybe_send_batched_emails
at the same time, mutating the shared data simultaneously.

Another less likely potential race condition was that
maybe_send_batched_emails after sending out its email, can call
ensure_timer(). If the consume function is run simultaneously
in the main thread, it will call ensure_timer() too, which,
given unfortunate timings, might lead to both calls setting a new Timer.

We add locking to the queue to avoid such race conditions.

Tested manually, by print debugging with the following setup:
1. Making handle_missedmessage_emails sleep 2 seconds for each email,
   and changed BATCH_DURATION to 1s to make the queue start working
   right after launching.
2. Putting a bunch of events in the queue.
3. ./manage.py process_queue --queue_name missedmessage_emails
4. Once maybe_send_batched_emails is called and while it's processing
the events, I pushed more events to the queue. That triggers the
consume() function and ensure_timer().

Before implementing the locking mechanism, this causes two threads
to run maybe_send_batched_emails at the same time, mutating each other's
shared data, causing a traceback such as

Exception in thread Thread-3:
Traceback (most recent call last):
  File "/usr/lib/python3.6/threading.py", line 916, in _bootstrap_inner
    self.run()
  File "/usr/lib/python3.6/threading.py", line 1182, in run
    self.function(*self.args, **self.kwargs)
  File "/srv/zulip/zerver/worker/queue_processors.py", line 507, in maybe_send_batched_emails
    del self.events_by_recipient[user_profile_id]
KeyError: '5'

With the locking mechanism, things get handled as expected, and
ensure_timer() exits if it can't obtain the lock due to
maybe_send_batched_emails still working.

Alex Vandiver 2928bbc8bd logging: Report stack_info on logging.exception calls.
The exception trace only goes from where the exception was thrown up
to where the `logging.exception` call is; any context as to where
_that_ was called from is lost, unless `stack_info` is passed as well.
Having the stack is particularly useful for Sentry exceptions, which
gain the full stack trace.

Add `stack_info=True` on all `logging.exception` calls with a
non-trivial stack; we omit `wsgi.py`.  Adjusts tests to match.

Mateusz Mandera d51afcf485 emails: Improve handling of timeouts when sending.
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.

Mateusz Mandera 8d2d64c100 CVE-2020-14215: Fix validation in PreregistrationUser queries.
The most import change here is the one in maybe_send_to_registration
codepath, as the insufficient validation there could lead to fetching
an expired PreregistrationUser that was invited as an administrator
admin even years ago, leading to this registration ending up in the
new user being a realm administrator.

Combined with the buggy migration in
0198_preregistrationuser_invited_as.py, this led to users incorrectly
joining as organizations administrators by accident.  But even without
that bug, this issue could have allowed a user who was invited as an
administrator but then had that invitation expire and then joined via
social authentication incorrectly join as an organization administrator.

The second change is in ConfirmationEmailWorker, where this wasn't a
security problem, but if the server was stopped for long enough, with
some invites to send out email for in the queue, then after starting it
up again, the queue worker would send out emails for invites that
had already expired.

Graham Bleaney 461d5b1a3e pysa: Introduce sanitizers, models, and inline marking safe.
This commit adds three `.pysa` model files: `false_positives.pysa`
for ruling out false positive flows with `Sanitize` annotations,
`req_lib.pysa` for educating pysa about Zulip's `REQ()` pattern for
extracting user input, and `redirects.pysa` for capturing the risk
of open redirects within Zulip code. Additionally, this commit
introduces `mark_sanitized`, an identity function which can be used
to selectively clear taint in cases where `Sanitize` models will not
work. This commit also puts `mark_sanitized` to work removing known
false postive flows.

Mateusz Mandera dd40649e04 queue_processors: Remove the slow_queries queue.
While this functionality to post slow queries to a Zulip stream was
very useful in the early days of Zulip, when there were only a few
hundred accounts, it's long since been useless since (1) the total
request volume on larger Zulip servers run by Zulip developers, and
(2) other server operators don't want real-time notifications of slow
backend queries.  The right structure for this is just a log file.

We get rid of the queue and replace it with a "zulip.slow_queries"
logger, which will still log to /var/log/zulip/slow_queries.log for
ease of access to this information and propagate to the other logging
handlers.  Reducing the amount of queues is good for lowering zulip's
memory footprint and restart performance, since we run at least one
dedicated queue worker process for each one in most configurations.

Wyatt Hoodes 82e7ad8e25 data exports: Handle pending and failed exports.
Prior to this change, there were reports of 500s in
production due to `export.extra_data` being a
Nonetype.  This was reproducible using the s3
backend in development when a row was created in
the `RealmAuditLog` table, but the export failed in
the `DeferredWorker`.  This left an entry lying
about that was never updated with an `extra_data`
field.

To fix this, we catch any exceptions in the
`DeferredWorker`, and then update `extra_data` to
encode the failure.  We also fix the fact that we
never updated the export UI table with pending exports.

These changes also negated the use for the somewhat
hacky `clear_success_banner` logic.

We've had a bug for a while that if any ScheduledEmail objects get

We solve this by using FromAddress placeholders strings in

Tim Abbott 783a77c532 queue processors: Flush per-request caches after each item.
Several of our queues are capable of doing work that includes
rendering markdown (outgoing_webhook, embedded_bots, embed_links, and
email_mirror).  As a result, it's essential that these don't cache
per-request data (specifically, realm filters) longer than they
should, making editing/deleting linkifiers potentially use old
settings until the relevant process was restarted.

Flushing these caches is extremely cheap (just clearing two
dictionaries) and thus is reasonable to do after every queue event,
rather than trying to do it only the ~1/3 of queues that specifically
do markdown processing.  We do the same in our middleware for
reset_queries.

It's not worth writing a test for this because it's very difficult to
create the test setup situation for this bug with a single test worker
process; one needs to edit the linkifier configuration in a different
process than the one sending the message in order to see the bug.

This was a much larger visible bug on Zulip 2.1.x, where the presence
of the message_sender queue meant that this would apply to messages
sent via a browser.

Note that while the test mocks the actual message

worker, so we have to set up a real stream for
testing (or we could have mocked that as well, but
it didn't seem necessary).  The setup queries add
to the amount of queries reported by the test,
plus the `get_stream` call.  I just made the
query count a digits regex, which is a little bit
lame, but I don't think it's worth risking test
flakes for this.

Anders Kaseorg ea6934c26d dependencies: Remove WebSockets system for sending messages.
Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013.  We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not.  Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.

While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.

This WebSockets code path had a lot of downsides/complexity,
including:

* The messy hack involving constructing an emulated request object to
  hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
  needs and must be provisioned independently from the rest of the
  server).
* A duplicate check_send_receive_time Nagios test specific to
  WebSockets.
* The requirement for users to have their firewalls/NATs allow
  WebSocket connections, and a setting to disable them for networks
  where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
  been poorly maintained, and periodically throws random JavaScript
  exceptions in our production environments without a deep enough
  traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
  server restart, and especially for large installations like
  zulipchat.com, resulting in extra delay before messages can be sent
  again.

As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients.  We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.

If we later want WebSockets, we’ll likely want to just use Django
Channels.

Mateusz Mandera c011d2c6d3 email_mirror: Migrate missed message addresses from redis to database.
Addresses point 1 of #13533.

MissedMessageEmailAddress objects get tied to the specific that was
missed by the user. A useful benefit of that is that email message sent
to that address will handle topic changes - if the message that was
missed gets its topic changed, the email response will get posted under
the new topic, while in the old model it would get posted under the
old topic, which could potentially be confusing.

Migrating redis data to this new model is a bit tricky, so the migration
code has comments explaining some of the compromises made there, and
test_migrations.py tests handling of the various possible cases that
could arise.

Mateusz Mandera e90866876c queue: Take advantage of ABC for defining abstract worker base classes.
QueueProcessingWorker and LoopQueueProcessingWorker are abstract classes
meant to be subclassed by a class that will define its own consume()
or consume_batch() method. ABCs are suited for that and we can tag
consume/consume_batch with the @abstractmethod wrapper which will
prevent subclasses that don't define these methods properly to be
impossible to even instantiate (as opposed to only crashing once
consume() is called). It's also nicely detected by mypy, which will
throw errors such as this on invalid use:

error: Only concrete class can be given where "Type[TestWorker]" is
expected
error: Cannot instantiate abstract class 'TestWorker' with abstract
attribute 'consume'

Due to it being detected by mypy, we can remove the test
test_worker_noconsume which just tested the old version of this -
raising an exception when the unimplemented consume() gets called. Now
it can be handled already on the linter level.

of issues with talking to the bouncer server. That's a better way of

did nothing.
The PushNotificationBouncerRetryLaterError exception will be nicely
handled by queue processors to retry sending again, and due to being a
JsonableError, it will also communicate the error to API users.

Mateusz Mandera 20b30e1503 push_notifs: Set up plumbing for retrying in case of bouncer error.
We add PushNotificationBouncerRetryLaterError as an exception to signal
an error occurred when trying to communicate with the bouncer and it
should be retried. We use JsonableError as the base class, because this
signal will need to work in two roles:
1. When the push notification was being issued by the queue worker
PushNotificationsWorker, it will signal to the worker to requeue the
event and try again later.
2. The exception will also possibly be raised (this will be added in the
next commit) on codepaths coming from a request to an API endpoint (for
example to add a token, to users/me/apns_device_token). In that case,
it'll be needed to provide a good error to the API user - and basing
this exception on JsonableError will allow that.

Tim Abbott 6407d0b1f9 push_notifications: Clear PushDeviceToken on API key change.
This includes adding a new endpoint to the push notification bouncer

When we add support for a user having multiple API keys, we may need
to add an additional key here to support removing keys associated with
just one client.

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.

We don't actually need to go to the memcached (falling back to the

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.

occurring in the time delta is checked to ensure that the weekly
limit is not exceeded.

The event is published to the 'deferred_work' queue processor to
prevent the export process from being killed after 60s.

Upon completion of the export the realm admin(s) are notified.

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.

Greg Price 9869153ae8 push notif: Send a batch of message IDs in one `remove` payload.
When a bunch of messages with active notifications are all read at
once -- e.g. by the user choosing to mark all messages, or all in a
stream, as read, or just scrolling quickly through a PM conversation
-- there can be a large batch of this information to convey.  Doing it
in a single GCM/FCM message is better for server congestion, and for
the device's battery.

The corresponding client-side logic is in zulip/zulip-mobile#3343 .

Existing clients today only understand one message ID at a time; so
accommodate them by sending individual GCM/FCM messages up to an
arbitrary threshold, with the rest only as a batch.

Also add an explicit test for this logic.  The existing tests
that happen to cause this function to run don't exercise the
last condition, so without a new test `--coverage` complains.

We adjust other APIs to match, but note that send_future_email does

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.

Steve Howell 69ee84bb14 refactor: Extract build_bot_request().
This fixes a couple things:

    * process_event() is a pretty vague name
    * returning tuples should generally be avoided
    * we were producing the same REST parameters in both
      subclasses
    * relative_url_path was always blank
    * request_kwargs was always empty

Now process_event() is called build_bot_request(),
and it only returns request data,
not a tuple of `rest_operation` and `request_data`.

By no longer returning `rest_operation`, there are
fewer moving parts.  We just have `do_rest_call` make
a POST call.

Steve Howell 16eff75e49 refactor: Simplify how we use base_url.

Tim Abbott da8f4bc0e9 push notifications: Add support for removing GCM push notifications.
This uses the recently introduced active_mobile_push_notification
flag; messages that have had a mobile push notification sent will have
a removal push notification sent as soon as they are marked as read.

Note that this feature is behind a setting,
SEND_REMOVE_PUSH_NOTIFICATIONS, since the notification format is not
supported by the mobile apps yet, and we want to give a grace period
before we start sending notifications that appear as (null) to
clients.  But the tracking logic to maintain the set of message IDs
with an active push notification runs unconditionally.

This is designed with at-least-once semantics; so mobile clients need
to handle the possibility that they receive duplicat requests to
remove a push notification.

We reuse the existing missedmessage_mobile_notifications queue
processor for the work, to avoid materially impacting the latency of
marking messages as read.

using these data on iOS.

  not need to be passed to bot_handler.handle_message().

Vishnu Ks 766511e519 actions: Mark all messages as read when user unsubscribes from stream.
This fixes a bug where, when a user is unsubscribed from a stream,
they might have unread messages on that stream leak.  While it might
seem to be a minor problem, it can cause significant problems for
computing the `unread_msgs` data structures, since it means we need to
add an extra filter for whether the user is still subscribed, either
in the backend or in the UI.

Fixes #7095.

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.

derAnfaenger c8a2702b9a embedded bots: Add functional state handler.
This replaces the former non-functional StateHandler
stub with a dictionary-like state object. Accessing it will
will read and store strings in the BotUserStateData model.

Each bot has a limited state size. To enforce this limit while
keeping data updates efficient, StateHandler caches the expensive
query for getting a bot's total state size. Assignments to a key
then only need to fetch that entry's previous size, if any, and
compare it to the new entry's size.

Tim Abbott f706f657c0 signup: Fix invitation emails not being cleared properly.
Previously, invitation reminder emails were only being cleared after a
successful signup if newsletter_data was available, since that was the
circumstance in which we were calling the relevant queue processor
code.  Now, we (1) clear them when a human user finishes signing up
and (2) correctly clear them using the 'address' field of
ScheduleEmail, not user_id.

Steve Howell ba397b5109 Use user_ids, not full objects, in render path.
There is no reason for either render_incoming_message() or

By only asking for user_ids, we save extra queries in two
callpaths and we make it easier to start using user_ids in
do_send_messages().

Abhijeet Kaur 5980d420a8 Embedded bots: Fix minor errors to make embedded bots/service run.
Splitting bot_lib.py file into 2 files led to unnecessary
redirection of the code workflow. For an embedded bot/service to
send a reply, it was being redirected 3 times.

First, the code flow comes to "EmbeddedBotHandler" class to send
reply, then it goes to the common function in "zulip_bots/lib.py",
then it would come back to "EmbeddedBotHandler". Later on, if we
create an abstract class, from where the bot work flow would
directly hit and then from there it is classified into
EmbeddedBotHandler or ExternalBotHandler and accordingly it would
get redirected.

Now, first the bot flow goes to it's handler class External or
Embedded (where we pass that this is External or Embedded bot as
parameter) and then goes to a common point and then comes back to
the same class.

reloader will restart the process. To reload, we send SIGUSR1(10)
signal from consumers to a handler in process_queue which then
exits with status code 3.

- For single worker per process:
Catch the SIGUSR1 and quit; supervisorctl will restart the worker
automatically.

Also:
* Converts the sender name to always be "Zulip", if the from_email used to
  be settings.NOREPLY_EMAIL_ADDRESS or settings.ZULIP_ADMINISTRATOR.

* Changes the default value of settings.NOREPLY_EMAIL_ADDRESS in the
