Aman Agrawal cda7b2f539 deletion: Add support for bulk message deletion events.
This is designed to have no user-facing change unless the client
declares bulk_message_deletion in its client_capabilities.

Clients that do so will receive a single bulk event for bulk deletions
of messages within a single conversation (topic or PM thread).

Backend implementation of #15285.

Anders Kaseorg 365fe0b3d5 python: Sort imports with isort.
Fixes #2665.

Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.

Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start.  I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

This commit was split by tabbott; this piece covers the vast majority

Mateusz Mandera 4283a513d4 tornado: Reuse retry_event functions for failures in tornado queues.
We use retry_event in queue_processors.py to handle trying on failures,
without getting stuck in permanent retry loops if the event ends up
leading to failure on every attempt and we just keep sending NACK to
rabbitmq forever (or until the channel crashes). Tornado queues haven't
been using this, but they should.

Tim Abbott a373387009 tornado: Fix parsing of delete_message events with no users.
The change in 180d8abed6, while correct
for the Django part of the codebase, had the nasty side effect of
exposing a failure mode in the process_notification logic if the users
list was empty.

This, in turn, could cause our process_notification code to fail with
an IndexError when trying to process the event, which would result in
that tornado process not automatically recovering, due to the outer
try/except handler for consume triggering a NACK and thus repeating
the event.

Udit107710 ef741bf317 messages: Return shallow copy of message object.
When more than one outgoing webhook is configured,
the message which is send to the webhook bot passes
through finalize_payload function multiple times,
which mutated the message dict in a way that many keys
were lost from the dict obj.

This commit fixes that problem by having
`finalize_payload` return a shallow copy of the
incoming dict, instead of mutating it.  We still
mutate dicts inside of `post_process_dicts`, though,
for performance reasons.

This was slightly modified by @showell to fix the
`test_both_codepaths` test that was added concurrently
to this work.  (I used a slightly verbose style in the
tests to emphasize the transformation from `wide_dict`
to `narrow_dict`.)

I also removed a deepcopy call inside
`get_client_payload`, since we now no longer mutate
in `finalize_payload`.

Finally, I added some comments here and there.

For testing, I mostly protect against the root
cause of the bug happening again, by adding a line
to make sure that `sender_realm_id` does not get
wiped out from the "wide" dictionary.

A better test would exercise the actual code that
exposed the bug here by sending a message to a bot
with two or more services attached to it.  I will
do that in a future commit.

Fixes #14384

Steve Howell 4c51a94bcd message: Move transitional shim for delivery email.
If we have an old event that's missing the field
`sender_delivery_email`, we now patch it at the top
of `process_message_event`, rather than for each call
to `get_client_payload`.  This will make an upcoming
commit a bit easier to reason about.  Basically, it's
simpler to shim the incoming event one time rather
than doing it up to four times.  We know that
`get_client_payload` is non-destructive, because it
does a deepcopy.

Tim Abbott 2aab71e153 event_queue: Fix confusing event_queue.push interface.
In e3ad9baf1d, we introduced yet another
bug where we incorrectly shared event dictionaries between multiple
queues.

Fortunately, the logging that reports on "event was not in the queue"
issues worked and detected this on chat.zulip.org, but this is a clear
indication that the comments we have around this system were not
sufficient to produce correct behavior.

We fix this by changing event_queue.push, the code that mutates the
event dictionaries, to do the shallow copies itself.  The only
downside here is process_message_event, a relatively low-traffic code
path, does an extra per-queue dictionary copy.  Given that presence,
heartbeat, and message reading events are likely more traffic and
dealing with HTTP is likely much more expensive than a dictionary
copy, this probably doesn't matter performance-wise.

(And if profiling later finds it is, there are potential workarounds
like passing a skip_copy argument we can do).

Tim Abbott 0ed0bb6828 messages: Add email/push notifications for wildcard mentions.

Tim Abbott 7953e23d49 event_queue: Actually fix missing copy for edit-message events.
Apparently, our edit-message events did not guarantee that the outer
wrapper dictionary, which is intended to be unique for each client,
was unique for every client (instead only ensuring it was unique for
each user).

This led to clients unexpectedly getting last_event_id validation
errors in this code path when a user had multiple connected clients,
because the linear ordering of event IDs within a given queue was
corrupted.

In fd2a63b049, we accidentally fixed
this issue with a different set of userdata events, without fixing the
edit-message event bug.  This commit fixes the remaining issue.

Tim Abbott 58307f80aa event_queue: Stop mocking push notifications in most tests.
Historically, queue_json_publish had a special third argument that was
basically its default mock behavior in the test suite.  We've been
migrating away from that model, because it was confusing and resulted
in poor test coverage of our queue worker code paths; this was one of
the last holdouts.

As it turns out, we don't exercise this code path in a way that
impacts tests much; the main downside of this change is a likely small
penalty to performance of the full test suite when sending private
messages.

Tim Abbott 02ae71f27f api: Stop using API keys for Django->Tornado authentication.
As part of our effort to change the data model away from each user
having a single API key, we're eliminating the couple requests that
were made from Django to Tornado (as part of a /register or home
request) where we used the user's API key grabbed from the database
for authentication.

Instead, we use the (already existing) internal_notify_view
authentication mechanism, which uses the SHARED_SECRET setting for
security, for these requests, and just fetch the user object using
get_user_profile_by_id directly.

Tweaked by Yago to include the new /api/v1/events/internal endpoint in
the exempt_patterns list in test_helpers, since it's an endpoint we call
through Tornado. Also added a couple missing return type annotations.

Tim Abbott 58a7a390c8 event_queue: Call build_offline_notification unconditionally.
Previously, maybe_enqueue_notifications had this very subtle logic,
where it set the notice variable only inside the block for push
notifications, but then also used it inside the block for email
notifications.

This "worked", because previously the conditions for push
notifications were always true if the conditions for email
notifications were, but the code was unnecessarily confusing.  The
only good reason to write it this way is if build_offline_notification
was expensive; in fact, the most expensive thing it does is calling
time.time(), so that reason does not apply here.

This was further confusing, in that in the original logic, we relied
on the fact that push notification code path edited the "notice"
dictionary for further processing.

Instead, we just call it separately and setup the data separately in

Steve Howell 431ede77c6 minor: Clean up how we set flags in events.
This is basically a simple fix, where we consistently set
`flags` to an empty array when we pass it around.  The history
here is that we had kind of a nasty bug from setting it to
`None`, which only showed up in the somewhat obscure circumstance
of somebody subscribing to all stream events in our API.

A `None` value is not properly handled in this function, which

of code on our test server:

This method was new in Tornado 4.0.  It saves us from having to get
the time ourselves and do the arithmetic -- which not only makes the
code a bit shorter, but also easier to get right.  Tornado docs (see
http://www.tornadoweb.org/en/stable/ioloop.html) say we should have
been getting the time from `ioloop.time()` rather than hardcoding
`time.time()`, because the loop could e.g. be running on the
`time.monotonic()` clock.

Steve Howell 2bbfda041a Support client_gravatar field for event registration.
This commit allows clients to register client_gravatar=True, and
then we recognize that flag for message events.  If the flag is
True, we will not calculate gravatar URLs and let the clients do
it themselves.  (Clients can calculate gravatar URLs based on
emails with just a little bit of code.)
2017-11-07 10:42:17 -08:00
Steve Howell 88e1e284bb Restructure send-message code for gravatars.
This refactoring doesn't change behavior, but it sets us up
to more easily handle a register setting for `client_gravatar`,
which will allow clients to tell us they're going to compute
their own gravatar URLs.

The `client_gravatar` flag already exists in our code, but it
is only used for Django views (users/messages) but not for
Zulip events.

The main change is to move the call to `set_sender_avatar` into
`finalize_payload`, which adds the boolean `client_gravatar`
parameter to that function.  And then we update various callers
to supply that flag.

One small performance benefit of this change is that we now
lazily compute the client message payloads in
`event_queue.process_message_event` now, so this will improve
performance if all interested clients have the same value of
`apply_markdown`.  But the change here is really preparing us
for the additional boolean parameter, which will cause us to
have four variations of the payload.

Steve Howell 635675fe48 Reduce queries needed for sending messages.
In do_send_messages, we only produce one dictionary for
the event queues, instead of different flavors for text
vs. html.  This prevents two unnecessary queries to the
database.

It also means we only put one dictionary on the "message"
event queue instead of two, albeit a wider one that has
some values that won't be sent to the actual clients.

This wider dictionary from MessageDict.wide_dict is also
used for the `feedback_messages` queue and service bot
queues.  Since the extra fields are possibly useful down
the road, and they'll just be ignored for now, we don't
bother to remove them.  Also, those queue processors won't
have access to `content_type`, which they shouldn't need.

Tim Abbott 513b6d624f notifications: Fix double-sending in missedmessage_hook.
While the missedmessage_hook logic originally did a reasonably good
job of avoiding double-sending notifications, there was a corner case
it didn't handle, namely a user who had been presence-idle when a
message was sent and became also event-queue-idle as well within the
next 10 minutes.  For those users, they got a notification at message
send time, and the missedmessage_hook would deliver it a second time.

We fix this by just checking the conveniently available push_notified
and email_notified variables that indicate whether the message already
had a notification triggered.

Fixes #7031.

Steve Howell aae0b2a826 Notify offline users about edited stream messages.
We now do push notifications and missed message emails
for offline users who are subscribed to the stream for
a message that has been edited, but we short circuit
the offline-notification logic for any user who presumably
would have already received a notification on the original
message.

This effectively boils down to sending notifications to newly
mentioned users.  The motivating use case here is that you
forget to mention somebody in a message, and then you edit
the message to mention the person.  If they are offline, they
will now get pushed notifications and missed message emails,
with some minor caveats.

We try to mostly use the same techniques here as the
send-message code path, and we share common code with the
send-message path once we get to the Tornado layer and call
maybe_enqueue_notifications.

The major places where we differ are in a function called
maybe_enqueue_notifications_for_message_update, and the top
of that function short circuits a bunch of cases where we
can mostly assume that the original message had an offline
notification.

We can expect a couple changes in the future:

    * Requirements may change here, and it might make sense
      to send offline notifications on the update side even
      in circumstances where the original message had a
      notification.

    * We may track more notifications in a DB model, which
      may simplify our short-circuit logic.

In the view/action layer, we already had two separate codepaths
for send-message and update-message, but this mostly echoes
what the send-message path does in terms of collecting data
about recipients.

Greg Price 9faa44af60 JsonableError: Optionally carry error codes and structured data.
This provides the main infrastructure for fixing #5598.  From here,
it's a matter of on the one hand upgrading exception handlers -- the
many except-blocks in the codebase that look for JsonableError -- to
look beyond the string `msg` and pass on the machine-readable full
error information to their various downstream recipients, and on the
other hand adjusting places where we raise errors to take advantage
of this mechanism to give the errors structured details.

In an ideal future, I think all exception handlers that look (or
should look) for a JsonableError would use its contents in structured
form, never mentioning `msg`; but the majority of error sites might
continue to just instantiate JsonableError with a string message.  The
latter is the simplest thing to do, and probably most error types will
never have code looking for them specifically.

Because the new API refactors the `to_json_error_msg` method which was
designed for subclasses to override, update the 4 subclasses that did
so to take full advantage of the new API instead.

Steve Howell 475eb21a5e Revert commits related to client_message_id.
I pushed a bunch of commits that attempted to introduce
the concept of `client_message_id` into our server, as
part of cleaning up our codepaths related to messages you
sent (both for the locally echoed case and for the host
case).

When we deployed this, we had some strange failures involving
double-echoed messages and issues advancing the pointer that appeared
related to #5779.  We didn't get to the bottom of exactly why the PR
caused havoc, but I decided there was a cleaner approach, anyway.
2017-07-14 12:13:35 -07:00
Steve Howell 8fbb55df85 Introduce client_message_id on the server.
We are deprecating local_id/local_message_id on the Python server.
Instead of the server knowing about the client's implementation of
local id, with the message id = 9999.01 scheme, we just send the
server an opaque id to send back to us.

This commit changes the name from local_id -> client_message_id,
but it doesn't change the actual values passed yet.

The goal for client_key in future commits will be to:
    * Have it for all messages, not just locally rendered messages
    * Not have it overlap with server-side message ids.

The history behind local_id having numbers like 9999.01 is that
they are actually interim message ids and the numerical value is
used for rendering the message list when we do client-side rendering.
