Steve Howell 69be97e365 pointer: Remove pointer from API and page_params.
There is still some miscellaneous cleanup that
has to happen for things like analytics queries
and dead code in node tests, but this should
remove the main use of pointers in the backend.

(We will also still need to drop the DB field.)

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

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.

Pragati Agrawal bd9b74436c org settings: Enable message_retention_days in org settings UI.
Since production testing of `message_retention_days` is finished, we can
enable this feature in the organization settings page. We already had this
setting in frontend but it was bit rotten and not rendered in templates.

Here we replaced our past text-input based setting with a
dropdown-with-text-input setting approach which is more consistent with our
existing UI.

Along with frontend changes, we also incorporated a backend change to
handle making retention period forever. This change introduces a new
convertor `to_positive_or_allowed_int` which only allows positive integers
and an allowed value for settings like `message_retention_days` which can
be a positive integer or has the value `Realm.RETAIN_MESSAGE_FOREVER` when
we change the setting to retain message forever.

This change made `to_not_negative_int_or_none` redundant so removed it as
well.

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.

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.

Mateusz Mandera 89394fc1eb middleware: Use request.user for logging when possible.
Instead of trying to set the _requestor_for_logs attribute in all the
relevant places, we try to use request.user when possible (that will be
when it's a UserProfile or RemoteZulipServer as of now). In other
places, we set _requestor_for_logs to avoid manually editing the
request.user attribute, as it should mostly be left for Django to manage
it.
In places where we remove the "request._requestor_for_logs = ..." line,
it is clearly implied by the previous code (or the current surrounding
code) that request.user is of the correct type.

Tim Abbott 1ea2f188ce tornado: Rewrite Django integration to duplicate less code.
Since essentially the first use of Tornado in Zulip, we've been
maintaining our Tornado+Django system, AsyncDjangoHandler, with
several hundred lines of Django code copied into it.

The goal for that code was simple: We wanted a way to use our Django
middleware (for code sharing reasons) inside a Tornado process (since
we wanted to use Tornado for our async events system).

As part of the Django 2.2.x upgrade, I looked at upgrading this
implementation to be based off modern Django, and it's definitely
possible to do that:
* Continue forking load_middleware to save response middleware.
* Continue manually running the Django response middleware.
* Continue working out a hack involving copying all of _get_response
  to change a couple lines allowing us our Tornado code to not
  actually return the Django HttpResponse so we can long-poll.  The
  previous hack of returning None stopped being viable with the Django 2.2
  MiddlewareMixin.__call__ implementation.

But I decided to take this opportunity to look at trying to avoid
copying material Django code, and there is a way to do it:

* Replace RespondAsynchronously with a response.asynchronous attribute
  on the HttpResponse; this allows Django to run its normal plumbing
  happily in a way that should be stable over time, and then we
  proceed to discard the response inside the Tornado `get()` method to
  implement long-polling.  (Better yet might be raising an
  exception?).  This lets us eliminate maintaining a patched copy of
  _get_response.

* Removing the @asynchronous decorator, which didn't add anything now
  that we only have one API endpoint backend (with two frontend call
  points) that could call into this.  Combined with the last bullet,
  this lets us remove a significant hack from our
  never_cache_responses function.

* Calling the normal Django `get_response` method from zulip_finish
  after creating a duplicate request to process, rather than writing
  totally custom code to do that.  This lets us eliminate maintaining
  a patched copy of Django's load_middleware.

* Adding detailed comments explaining how this is supposed to work,
  what problems we encounter, and how we solve various problems, which
  is critical to being able to modify this code in the future.

A key advantage of these changes is that the exact same code should
work on Django 1.11, Django 2.2, and Django 3.x, because we're no
longer copying large blocks of core Django code and thus should be
much less vulnerable to refactors.

There may be a modest performance downside, in that we now run both
request and response middleware twice when longpolling (once for the
request we discard).  We may be able to avoid the expensive part of
it, Zulip's own request/response middleware, with a bit of additional
custom code to save work for requests where we're planning to discard
the response.  Profiling will be important to understanding what's
worth doing here.

Tim Abbott 986706c7e5 tornado: Use common code for copying headers.
This fixes a bug where our asynchronous requests were only copying the
Content-Type header (i.e. the one case where we're noticed) from the
Django HttpResponse.  I'm not sure what the impact of this would be;
the rate-limiting headers rarely come up when breaking a long-polled
request.  But it seems clearly an improvement to do this in a
consistent fashion.

Only the headers piece is a change; in Tornado

    self.finish(x)

is equivalent to:

    self.write(x)
    self.finish()

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).

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.

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.

Anders Kaseorg 86a7fdddd7 events: Check last_event_id for validity, take 2.
This verifies that the client passed a last_event_id that actually
came from the queue instead of making up an ID from the future.  It

clients are expected not to do so.

The previous version of this commit (commit

Tim Abbott 8be3df0e29 tornado: Fix bugs in Tornado autoreload library.
This fixes two issues:

* The syntax check logic we had for zerver.tornado.autoreload would
  end up clearing _reload_hooks if one of the files that had changed
  was zerver.tornado.autoreload itself (because we'd had re-imported
  the current module), which could be incredibly confusing when trying
  to test the autoreload logic.  It seems better to just not run the
  syntax check for syntax errors in this file.

  Similarly, because reloading event_queue.py would destroy the state
  in the queues, we avoid that as well.

* We make sure to flush stdout after running and reload hooks, to make
  sure their output reaches the user.

Tim Abbott a43b2f7a43 tornado: Fix incorrect import of autoreload library.
We were apparently not running our own forked Tornado autoreload

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
each code path.

Tim Abbott ae0a929988 tornado: Ensure that tornado doesn't autoreload into syntax errors.
We've for a long time been plagued by run-dev.py needing to be
restarted every time one does a rebase that has merge conflicts,
because the Tornado process restarts itself into a syntax error and
crashes.

This fixes the Tornado autoreload process to check explicitly for
whether files actually syntax-check before trying to actually reload
the Tornado process to run that code.

There are a few things that are a bit janky:
* Ideally, this would go into Tornado upstream
* We removed the `_watched_files` feature, which we weren't using.
* Ideally, we'd use something other than `importlib.reload` that just
  does the syntax-check without adjusting the state within our current
  process.

Fixes #4351.

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.

The only consumers of this field were the mobile app and the
apply-events-to-unread-counts logic.  Both of these will now
use `flags` instead.

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 b63e995e82 tornado: Fix a Redis-caused str/bytes bug in `status_inquiries`.
Because the Redis client returns exclusively bytes -- even for
hash keys -- even on Python 3, the test `'response' in status`
was always returning false, and the line that tries to decode
as JSON was never running, so we were passing `response`
through as a `bytes` object encoding some JSON.

I'm not sure what the impact of this bug was, and in particular
whether something downstream would have fudged it to make up for
this error.

Greg Price 45b718a2a2 tornado: Use the new structured JsonableError API for /json/events errors. 2017-07-24 16:41:22 -07:00
Greg Price 124d623d05 tornado/socket: Replace an ad-hoc error class with JsonableError.
The one purpose this exception was serving was to carry a message
in `msg`.  We can do that with `JsonableError`, and as a bonus replace
a repetition of the familiar "'result': 'error', ..." JSON pattern
with a call to a common implementation.

Also wrap the error messages for translation -- we hadn't been doing
that, oops.  Our linter notices that issue now that it's the familiar
JsonableError class.

There's one other potential change in behavior here: this
except-clause might now catch a JsonableError raised from some other
code.  That seems like a bonus, if so; the handler isn't doing
anything actually specific to this code, and the more exceptions it
successfully turns into proper error responses to the client and lines
in the log, the better.
2017-07-24 16:41:22 -07:00
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.

Greg Price ff5013c619 JsonableError: Add types, and eliminate duck-typing.
In order to benefit from the modern conveniences of type-checking,

the places where we receive a JsonableError and try to use it.
Simplify those by using straightforward standard typing.

Umair Khan b4d49720b0 tornado: Close queue connection on reload.
Tornado reloads the app whenever there is a change in code. Due to this,
new connection is created to the client which also results in a new
channel. To avoid creating two channels for the queue in the RabbitMQ
broker we should close the old channel. Otherwise messages sent to the
queue will be distributed among these two channels in a round robin
scheme and we will end up losing one message since one of the channels
doesn't have an active consumer.

This commit closes the connection to the queue whenever Tornado reloads
the application using add_reload_hook().

Fixes #5824.

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.

Rafid Aslam 78f3fd7999 API: Expose `is_mentioned` in `message` dictionary.
Expose `is_mentioned` in `message` dict which contains
boolean value about our account is mentioned in the message
content or not.

This is already available via `flags`, but it seems worth making this
data point more explicit, given its importance in writing bots.

Fixes #2667.

Reid Barton ecfa397567 Fix several type annotations for mypy 0.4.6 compatibility.

thinks that the first type in the annotation is supposed to be
the type of `self`, a new mypy feature which we are not intending
to use here.
