We previously forked tornado.autoreload to work around a problem where
it would crash if you introduce a syntax error and not recover if you
fix it (https://github.com/tornadoweb/tornado/issues/2398).
A much more maintainable workaround for that issue, at least in
current Tornado, is to use tornado.autoreload as the main module.

Mypy can’t follow absolute imports based on directories other than the
root. This was hiding some type errors due to ignore_missing_imports.

This is a straightforward upgrade in terms of changes needed.
Necessary changes were:
- Set `DEFAULT_AUTO_FIELD`
https://docs.djangoproject.com/en/3.2/releases/3.2/#customizing-type-of-auto-created-primary-keys
- `The default_app_config application configuration variable is deprecated, due
to the now automatic AppConfig discovery.`
https://docs.djangoproject.com/en/3.2/releases/3.2/#automatic-appconfig-discovery
To handle this one, we can remove default_app_config from
zerver/__init__.py because it satisfies what release notes describe in
https://docs.djangoproject.com/en/3.2/releases/3.2/#automatic-appconfig-discovery:
"Most pluggable applications define an AppConfig subclass in an apps.py
submodule. Many define a default_app_config variable pointing to this
class in their __init__.py. When the apps.py submodule exists and
defines a single AppConfig subclass, Django now uses that configuration
automatically, so you can remove default_app_config."
An important note is that rebuild-test-database needs to be run after
this upgrade in dev environment - if tests are run with test db that was
built on the previous version, they will fail due to a mysterious bug
(?), where changing attributes of a user and .save()ing after logging in
in the test via self.login_user, causes getting logged out - the next
requests via self.client_get etc. are unauthed for some reason,
unless self.login_user is called again. This behavior is no longer
exhibited upon rebuilding the test db - and I can't reproduce it in
production or dev db. So this can likely be reasonably dismissed as some
quirk of the test client system that won't be relevant in the future and
doesn't impact production.
GitHub Actions supports doing more than just CI,
and so in some contexts it's less obvious that we're
talking about just the CI if we refer to it instead of CircleCI.
This commit renames --force argument used with various tests to
--skip-provision-check. As a consequence of this name change all other
files that set --force option for the test commands have been updated.
This change is done in order to provide more clarity for using this
option for runnning tests.
This commit addresses issue #17455.
This commit moves --force option used with various tests to
test-scripts.py to have it alongside the logic that does provisioning
status assertion.
This is a step towards providing more clarity over use of this
argument with tests as asked in issue #17455.
user_profile will be None for web_public_guests here. Hence, for
settings (of which most be inaccessible by web public guest),
which require a user_profile, we either set an empty value for
them or set them to a default value. This will help render
the frontend or extend support to our clients without breaking
a lot of code.
Tweaked by tabbott to add many comments.
This was a broken abstraction that returned to its caller within
multiple forked processes on exceptions, and encouraged ignoring the
error code (as all of its callers did).

This commit adds automatic detection of extra output (other than
printed by testing library or tools) in stderr and stdout by code under
test test-backend when it is run with flag --ban-console-output.
It also prints the test that produced the extra console output.
Fixes: #1587.

Rename rest of function names, classes and comments containing bugdoown
to markdown in test_markdown.py. Also change the refactored classes and
functions occurences in other files.
This commit is part of series of commits aimed at renaming bugdown to
markdown.
Rename the file and all the refrences to file and module test_bugdown.py
to test_markdown.py.
This commit is part of series of commit that renames bugdown to markdown.
This commit is first of few commita which aim to change all the
bugdown references to markdown. This commits rename the files,
file path mentions and change the imports.
Variables and other references to bugdown will be renamed in susequent
commits.
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.

* codecov needs `.coverage` file in the pwd to upload coverage
results.
* concurrency='multiprocessing' forces `.coverage` file to have a

mock is just a backport of the standard library’s unittest.mock now.
The SAMLAuthBackendTest change is needed because
MagicMock.call_args.args wasn’t introduced until Python
3.8 (https://bugs.python.org/issue21269).
The PROVISION_VERSION bump is skipped because mock is still an
indirect dev requirement via moto.

We remove the `generate_fixtures` option here mostly
for simplicity, but in particular to facilitate
an upcoming commit to simplify the job of
`generate-fixtures` (and remove its `--force` option).
The command line option here for `test-backend`
was really calling `generate_fixtures --force`,
which we're about to rename `tools/rebuild-test-database`.
The `test-backend` tools is already smart about catching
up on migrations, so we generally don't need to tell it
to repair the database.
And if the database does get corrupt, you can just do
it directly with `tools/rebuild-test-database`.
This eliminates the `use_force` flag in
`update_test_databases_if_required`, which was easy
to confuse with `rebuild_test_database`.
The other caller wasn't using `use_force`.
Generated by `pyupgrade --py3-plus --keep-percent-format` on all our
Python code except `zthumbor` and `zulip-ec2-configure-interfaces`,
followed by manual indentation fixes.

Without calling cov.erase() the data file seems to persist and even
pollute future test runs if not removed. Registering an atexit handler
seems like a good, and reasonably clean way to ensure the cleanup
happens.
Fixes#13933.
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.
responses is an module analogous to httpretty for mocking external
URLs, with a very similar interface (potentially cleaner in that it
makes use of context managers).
The most important (in the moment) problem with httpretty is that it
breaks the ability to use redis in parts of code where httpretty is
enabled. From more research, the module in general has tendency to
have various troublesome bugs with breaking URLs that it shouldn't be
affecting, caused by it working at the socket interface layer. While
those issues could be fixed, responses seems to be less buggy (based
on both third-party reports like ckan/ckan#4755 and our own experience
in removing workarounds for bugs in httpretty) and is more actively
maintained.
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.
