This is later used for supporting RFC 6570 URI Template in place of the
URL format string that we were using for linkifiers.

Primary goal of library replacement is improving execution speed.
This commit should not affect the functionality of the system
or make any changes to it.
Previously, `QuerySet` does not support isinstance check since it is
defined to be generic in django-stubs. In a recent update, such check is
possible by using `QuerySetAny`, a non-generic alias of `QuerySet`.

This adds tests for more corner cases, in exchange for dropping the
query count tests, which were of dubious utility. It also adds the
time-machine library to mock the current time to test that the limits
do expire.
The `django-sendfile2` module unfortunately only supports a single
`SENDFILE` root path -- an invariant which subsequent commits need to
break. Especially as Zulip only runs with a single webserver, and
thus sendfile backend, the functionality is simple to inline.
It is worth noting that the following headers from the initial Django
response are _preserved_, if present, and sent unmodified to the
client; all other headers are overridden by those supplied by the
internal redirect[^1]:
- Content-Type
- Content-Disposition
- Accept-Ranges
- Set-Cookie
- Cache-Control
- Expires
As such, we explicitly unset the Content-type header to allow nginx to
set it from the static file, but set Content-Disposition and
Cache-Control as we want them to be.

This way Puppeteer doesn’t have to re-download Chromium every time we
install new JavaScript dependencies.

Note that django_stubs_ext is required to be placed within common.in
because we need the monkeypatched types in runtime; django-stubs
itself is for type checking only.
In the future, we would like to pin to a release instead of a git
revision, but several patches we've contributed upstream have not
appeared in a release yet.
We also remove the type annotation for RealmAuditLog.event_last_message_id
here instead of earlier because type checking fails otherwise.
Fixes#11560.
This includes the change from 28fde2ee27.
Only a minor bump is required because it has no effect on type
checking yet before django-stubs gets integrated.

The new release adds the commit:
20ac22b96d
Which allows us to get rid of the entire ugly override that was needed
to do this commit's job in our code. What we do here in this commit:
* Use django-scim2 0.17.1
* Revert the relevant parts of f5a65846a8
* Adjust the expected error message in test_exception_details_not_revealed_to_client
since the message thrown by django-scim2 in this release is slightly
different.
We do not have to add anything to set EXPOSE_SCIM_EXCEPTIONS, since
django-scim2 uses False as the default, which is what we want - and we
have the aforementioned test verifying that indeed information doesn't
get revealed to the SCIM client.
As a consequence:
• Bump minimum supported Python version to 3.7.
• Move Vagrant environment to Debian 10, which has Python 3.7.
• Move CI frontend tests to Debian 10.
• Move production build test to Debian 10.

TOR users are legitimate users of the system; however, that system can
also be used for abuse -- specifically, by evading IP-based
rate-limiting.
For the purposes of IP-based rate-limiting, add a
RATE_LIMIT_TOR_TOGETHER flag, defaulting to false, which lumps all
requests from TOR exit nodes into the same bucket. This may allow a
TOR user to deny other TOR users access to the find-my-account and
new-realm endpoints, but this is a low cost for cutting off a
significant potential abuse vector.
If enabled, the list of TOR exit nodes is fetched from their public
endpoint once per hour, via a cron job, and cached on disk. Django
processes load this data from disk, and cache it in memcached.
Requests are spared from the burden of checking disk on failure via a
circuitbreaker, which trips of there are two failures in a row, and
only begins trying again after 10 minutes.
In #20012, it was discovered that since our `zulip_bots` package
requires `importlib-metadata >= 3.6; python_version < "3.10"`
whereas the server requires
`importlib-metadata==4.8.1 ; python_version < "3.8". This results
in `importlib-metadata` not being installed on Python 3.8 and
Python 3.9. This commit resolves that discrepancy.

re2[1] compiles (strictly) regular expressions to deterministic finite
automata, which guarantees linear-time behavior; `google-re2` is a
drop-in replacement for the `re` module which uses re2 under the hood.

gitlint has a bunch of pinned requirements that hold back important
upgrades and conflict with other packages’ requirements. The gitlint
author has rejected proposals to unpin them because it might increase
the amount of maintenance he needs to do
(https://github.com/jorisroovers/gitlint/pull/133). That decision is
his to make, but _somebody_ needs to do the maintenance, so we
delegate it to Debian and Ubuntu. If that means using a significantly
older version of gitlint, that’s a tradeoff we need to make to keep
the rest of our requirements current.

Till now, we've been forking django-auth-ldap at
https://github.com/zulip/django-auth-ldap to put the
LDAPReverseEmailSearch feature in it, hoping to get it merged
upstream in https://github.com/django-auth-ldap/django-auth-ldap/pull/150
The efforts to get it merged have stalled for now however and we don't
want to be on the fork forever, so this commit puts the email search
feature as a clumsy workaround inside our codebase and switches to using
the latest upstream release instead of the fork.
Recommonmark is no longer maintained, and MyST-Parser is much more

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.
Previously the outgoing emails were sent over several SMTP
connections through the EmailSendingWorker; establishing a new
connection each time adds notable overhead.
Redefine EmailSendingWorker worker to be a LoopQueueProcessingWorker,
which allows it to handle batches of events. At the same time, persist
the connection across email sending, if possible.
The connection is initialized in the constructor of the worker
in order to keep the same connection throughout the whole process.
The concrete implementation of the consume_batch function is simply
processing each email one at a time until they have all been sent.
In order to reuse the previously implemented decorator to retry
sending failures a new method that meets the decorator's required
arguments is declared inside the EmailSendingWorker class. This
allows to retry the sending process of a particular email inside
the batch if the caught exception leaves this process retriable.
A second retry mechanism is used inside the initialize_connection
function to redo the opening of the connection until it works or
until three attempts failed. For this purpose the backoff module
has been added to the dependencies and a test has been added to
ensure that this retry mechanism works well.
The connection is closed when the stop method is called.
Fixes: #17672.
It does not seem like an official version supporting Webpack 4 (to say
nothing of 5) will be released any time soon, and we can reimplement
it in very little code.
