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
of files in Zulip, but excludes scripts/, tools/, and puppet/ to help
ensure we at least show the right error messages for Xenial systems.

We can likely further refine the remaining pieces with some testing.

Steve Howell 1b16693526 tests: Limit email-based logins.
We now have this API...

If you really just need to log in
and not do anything with the actual
user:

    self.login('hamlet')

If you're gonna use the user in the
rest of the test:

    hamlet = self.example_user('hamlet')
    self.login_user(hamlet)

If you are specifically testing
email/password logins (used only in 4 places):

    self.login_by_email(email, password)

And for failures uses this (used twice):

    self.assert_login_failure(email)

Tim Abbott 27edc18330 test_classes: Use realistic web and mobile User-Agent strings.
This fixes a confusing aspect of how our automated tests worked
previously, where we'd almost all HTTP requests in the unlikely
configuration with no User-Agent string specified.

We need to adjust query counts in a few tests that now are a bit
cheaper because they now can take advantage of a Client object created
in server_initialization.py in `process_client`.

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 993ed9c2b1 tornado: Remove stale user_profile_email field.
Since years ago, this field hasn't been used for anything other than
some logging that would be better off logging the user ID anyway.

It existed in the first place simply because we weren't passing the
user_profile_id to Tornado at all.

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
turns out one of our tests was making up such an ID, but legitimate
clients are expected not to do so.

The previous version of this commit (commit
e00d4be6d5, #12888) had to be reverted
(commit b86c5cc490) because it was
missing the `to_dict`/`from_dict` migration code.

Tim Abbott c3c7b33351 tests: Move clear_client_event_queues_for_testing to ZulipTestCase.
Following recent testing flakes that were traced down to this not
having been called causing `receiver_is_off_zulip` to depend on test
ordering, it makes sense to centralize this.

I think it should always have been in ZulipTestCase; it appears the
reason it wasn't from the beginning was that originally only
test_events.py interacted with it, and do_test there still needs to
call this directly (because it can be called multiple times within a
single test).  And then we did the wrong thing as expanded use of
Tornado event_queue code in tests to more of the codebase.

Tim Abbott 8ceb3b88ad test_tornado: Fix leaking of event queue state.
Apparently, we weren't calling the proper clear functions inside the

(In this case, a new test for mobile push notifications that assumed
receiver_is_off_zulip() was always true failed after this was run).

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.
