Steve Howell 746cc9e1f6 refactor: Extract browser_history module.
This mainly extracts a new module called
browser_history. It has much fewer dependencies
than hashchange.js, so any modules that just
need the smaller API from browser_history now
have fewer transitive dependencies.

Here are some details:
    * Move is_overlay_hash to hash_util.
    * Rename hashchange.update_browser_history to
      brower_history.update
    * Move go_to_location verbatim.
    * Remove unused argument for exit_overlay.
    * Introduce helper functions:
        * old_hash()
        * set_hash_before_overlay()
        * save_old_hash()

We now have 100% line coverage on the extracted
code.

Steve Howell dbf19fe8d7 refactor: Extract watchdog module.

Steve Howell 3e23c3b52c event system docs: Explain how to write event tests.
In this commit I attempt to make the docs for
writing `test_events` a little more oriented
toward telling the developer that they need to
write a test in `test_events`; in other words,
the tone is a bit more of how-to-do-it vs.
explaining the innards.

So I now start with a concrete example.

Then much of the copy related to `verify_action`
is the same as before this commit, but I rework
it a bit to be a bit more step-by-step, and I refer
back to the concrete example.

Finally, I explain the schema checking step, which
is all new copy, although for that, I mostly
instruct the developer to read event_schema.py
itself.

Steve Howell 504ec9d489 typing: Remove recipient-related complexity.
For historical reasons we were creating Recipient
objects at some point in the typing-notifications
codepath.  Now we just work with UserProfiles.
This removes some queries, as indicated by
the change to `len(queries)` in a couple of the
tests.

The one subtle thing that changes here is huddles.
If user 10 sends a typing notification that they
are talking to users 20 and 30, there might not
actually be a huddle for users 10/20/30, but
we were actually creating huddles on the fly!
There is no need to create huddles just for
typing notifications, since we don't even
share huddle ids with our clients.  The clients
just infer the huddles.

Some of the code that gets killed off here as
somewhat "collateral damage" is some
defensive code related to formerly supporting streams
in typing indicators.  The support for streams
was killed off almost as soon as we released
the feature, and the codepath is pretty clearly
user-centric at this point.
2020-02-28 12:46:20 -08:00
Steve Howell b26f2dcd4b typing: Deprecate emails in typing endpoint.
The only clients that should use the typing
indicators endpoint are our internal clients,
and they should send a JSON-formatted list
of user_ids.

Unfortunately, we still have some older versions
of mobile that still send emails.

In this commit we fix non-user-facing things
like docs and tests to promote the user_ids
interface that has existed since about version
2.0 of the server.

One annoyance is that we documented the
typing endpoint with emails, instead of the
more modern user_ids, which may have delayed
mobile converting to user_ids (and which
certainly caused confusion).  It's trivial
to update the docs, but we need to short
circuit one assertion in the openapi tests.

We also clean up the test structure for the
typing tests:

    TypingHappyPathTest.test_start_to_another_user
    TypingHappyPathTest.test_start_to_multiple_recipients
    TypingHappyPathTest.test_start_to_self
    TypingHappyPathTest.test_start_to_single_recipient
    TypingHappyPathTest.test_stop_to_another_user
    TypingHappyPathTest.test_stop_to_self

rht 41e3db81be dependencies: Upgrade to Django 2.2.10.
Django 2.2.x is the next LTS release after Django 1.11.x; I expect
we'll be on it for a while, as Django 3.x won't have an LTS release
series out for a while.

Because of upstream API changes in Django, this commit includes
several changes beyond requirements and:

* urls: django.urls.resolvers.RegexURLPattern has been replaced by
  django.urls.resolvers.URLPattern; affects OpenAPI code and related
  features which re-parse Django's internals.
  https://code.djangoproject.com/ticket/28593
* test_runner: Change number to suffix. Django changed the name in this
  ticket: https://code.djangoproject.com/ticket/28578
* Delete now-unnecessary SameSite cookie code (it's now the default).
* forms: urlsafe_base64_encode returns string in Django 2.2.
  https://docs.djangoproject.com/en/2.2/ref/utils/#django.utils.http.urlsafe_base64_encode
* upload: Django's File.size property replaces _get_size().
  https://docs.djangoproject.com/en/2.2/_modules/django/core/files/base/
* process_queue: Migrate to new autoreload API.
* test_messages: Add an extra query caused by .refresh_from_db() losing
  the .select_related() on the Realm object.
* session: Sync SessionHostDomainMiddleware with Django 2.2.

There's a lot more we can do to take advantage of the new release;
this is tracked in #11341.

Many changes by Tim Abbott, Umair Waheed, and Mateusz Mandera squashed
are squashed into this commit.

Fixes #10835.

Anders Kaseorg e257253e64 emoji_codes: Replace JS module with JSON module.
webpack optimizes JSON modules using JSON.parse("{…}"), which is
faster than the normal JavaScript parser.

Update the backend to use emoji_codes.json too instead of the three
separate JSON files.
