isort 5 knows not to reorder imports across function calls, so this
will stop isort from breaking our code.

- I fixed a typo with "lowerecase"
- I elaborated on the prefix before elaborating
on the rest of the message (i.e. went in correct
order).
- I split out the provision example (since we
talk about it some depth).
- I added more positive examples.
- I removed the distracting italics around the
good commit messages.
- I moved the "gather_subscriptions" commit to
the bottom of the list, since we elaborate
on that below the list.
This includes an experiment of having a draft of the 2.1.3 changelog,
which is helpful in avoiding duplication with the 2.2.0 changelog for
items we're planning to backport.
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* urls: django.urls.resolvers.RegexURLPattern has been replaced by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.
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.

This is a fairly involved set of changes, including changes that:
* Delete various legacy or semi-duplicated sections of testing.md.
Nobody needs to manually delete the postgres datbase anymore, as
reflected in the fact that the docs still mention postgres 9.1 from
Ubuntu Precise.
* Simplify the distracting heading section at the top of testing.md.
* Move content on manual testing to docs/development/using.md.
* Moves some content related to managing the database to
schema-migrations.md. (Resulting in some cleanups to that page as
well).
I ideally would have split this into smaller pieces.
This addresses confusion we had with some organizations where they
were surprised that with only LDAP enabled, the "invite more users"
feature was available.
Fixes#11685.
This legacy cross-realm bot hasn't been used in several years, as far
as I know. If we wanted to re-introduce it, I'd want to implement it
as an embedded bot using those common APIs, rather than the totally
custom hacky code used for it that involves unnecessary queue workers
and similar details.
Fixes#13533.
This correct various inaccuracies and adds a bulleted list structure
for better clarity.
I think there's a lot more that could be done here in the form of
linking to other pages, discussing restarting `run-dev.py`, etc.
Added a link from docs/development/using ("Using the Development
Environment") to ./authentication ("Authentication in the development
environment") to help people working on the authentication systems
or anyone who needs an API key.
Separate using.html into Server/Web/Mobile sections so that readers
will find what they're looking for more quickly. Server is at the top
because it contains information relevant to web and mobile developers,
e.g., that the `run-dev.py` console output will provide useful errors.
Fixes#13655.
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.

I added this tool a few years ago, and I did have
a vision for how it would improve our codebase, but
I can't remember exactly where I was going with it.
At this point the tool is just a little too noisy
to be helpful. An example of it creating confusion
was a recent PR where somebody was patching
user_circle_class in the PM list, and we already
had similar code in the buddy list, because they
use the same CSS. I mean, there was possibly a way
that the code could have been structured to remove
some of the duplication, but it probably would have
just moved the complexity around.
I just don't think it's worth maintaining the tool
at this point.
The well-known rowanj/gitx repository hasn't been updated since 2014.
Preferentially direct new contributors to gitx/gitx instead.
(We retain the rowanj repo as a fallback, since it has precompiled
releases available.)
This moves the mandatory configuration for options A/B/C into a single
bulleted list for each option, rather than split across two steps; I
think the result is significantly more readable.
It also fixes a bug where we suggested setting
AUTH_LDAP_REVERSE_EMAIL_SEARCH = AUTH_LDAP_USER_SEARCH in some cases,
whereas in fact it will never work because the parameters are
`%(email)s`, not `%(user)s`.
Also, now that one needs to set AUTH_LDAP_REVERSE_EMAIL_SEARCH, it
seems worth adding values for that to the Active Directory
instructions. Thanks to @alfonsrv for the suggestion.
This simplifies the RDS installation process to avoid awkwardly
requiring running the installer twice, and also is significantly more
robust in handling issues around rerunning the installer.
Finally, the answer for whether dictionaries are missing is available
to Django for future use in warnings/etc. around full-text search not
being great with this configuration, should they be required.
