This was added in 1fded25025, and is not
necessary for standard Zulip installs. While both Host: and
X-Forwarded-Host: are nominally untrusted, there is no reason to
complicate the deployment by defaulting it on.
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.

This commit changes the invite API to accept invitation
expiration time in minutes since we are going to add a
custom option in further commits which would allow a user
to set expiration time in minutes, hours and weeks as well.
This cache was added in da33b72848 to serve as a replacement for the
durable database cache, in development; the previous commit has
switched that to be the non-durable memcached backend.
The special-case for "in-memory" in development is mostly-unnecessary
in contrast to memcached -- `./tools/run-dev.py` flushes memcached on
every startup. This differs in behaviour slightly, in that if the
codepath is changed and `run-dev` restarts Django, the cache is not
cleared. This seems an unlikely occurrence, however, and the code
cleanup from its removal is worth it.
Failure to pull the default "zulip" value here can lead to
accidentally applying a `postgres_password` value which is unnecessary
and may never work.
For consistency, always skip password auth attempts for the "zulip"
user on localhost, even if the password is set. This mirrors the
behavior of `process_fts_updates`.
It’s built in to Jinja2 as of 2.9. Fixes “DeprecationWarning: The
'autoescape' extension is deprecated and will be removed in Jinja
3.1. This is built in now.”

We recently ran into a payload in production that didn't contain
an event type at all. A payload where we can't figure out the event
type is quite rare. Instead of letting these payloads run amok, we
should raise a more informative exception for such unusual payloads.
If we encounter too many of these, then we can choose to conduct a
deeper investigation on a case-by-case basis.
With some changes by Tim Abbott.
Having wantMessagesSigned=True globally means that it's also applied by
python3-saml to regular authentication SAMLResponses - making it require
the response to be signed, which is an issue because a feasible
alternative way that some IdPs (e.g. AzureAD) take by default is to sign
specifically the assertions in the SAMLResponse. This is also secure,
and thus we generally want to accept it.
Without this, the setting of wantMessagesSigned=True globally
in 4105ccdb17 causes a
regression for deployments that have already set up SAML with providers
such as AzureAD, making Zulip stop accepting the SAMLResponses.
Testing that this new logic works is handled by
test_saml_idp_initiated_logout_invalid_signature, which verifies that a
LogoutRequest without signature will be rejected.
The warning was fixed in python-jose 3.3.0, which we pulled in with
commit 61e1e38a00 (#18705).
This reverts commit 1df725e6f1 (#18567).

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.
Previously, our codebase contained links to various versions of the
Django docs, eg https://docs.djangoproject.com/en/1.8/ref/
request-response/#django.http.HttpRequest and https://
docs.djangoproject.com/en/2.2/ref/settings/#std:setting-SERVER_EMAIL
opening a link to a doc with an outdated Django version would show a
warning "This document is for an insecure version of Django that is no
longer supported. Please upgrade to a newer release!".
Most of these links are inside comments.
Following the replacement of these links in our docs, this commit uses
a search with the regex "docs.djangoproject.com/en/([0-9].[0-9]*)/"
and replaces all matches with "docs.djangoproject.com/en/3.2/".
All the new links in this commit have been generated by the above
replace and each link has then been manually checked to ensure that
(1) the page still exists and has not been moved to a new location
(and it has been found that no page has been moved like this), (2)
that the anchor that we're linking to has not been changed (and it has
been found that no anchor has been changed like this).
One comment where we mentioned a Django version in text before linking
to a page for that version has also been changed, the comment
mentioned the specific version when a change happened, and the history
is no longer relevant to us.
This more closely matches email_change_by_user and
password_reset_form_by_email limits; legitimate users are unlikely to
need to send more than 5 emails to themselves during a day.
Both `create_realm_by_ip` and `find_account_by_ip` send emails to
arbitrary email addresses, and as such can be used to spam users.
Lump their IP rate limits into the same bucket; most legitimate users
will likely not be using both of these endpoints at similar times.
The rate is set at 5 in 30 minutes, the more quickly-restrictive of
the two previous rates.
SOCIAL_AUTH_SUBDOMAIN was potentially very confusing when opened by a
user, as it had various Login/Signup buttons as if there was a realm on
it. Instead, we want to display a more informative page to the user
telling them they shouldn't even be there. If possible, we just redirect
them to the realm they most likely came from.
To make this possible, we have to exclude the subdomain from
ROOT_SUBDOMAIN_ALIASES - so that we can give it special behavior.
This fixes error found with django-stubs and it is a part of #18777.
Note that there are various remaining errors that need to be fixed in
upstream or elsewhere in our codebase.
Closes#19287
This endpoint allows submitting multiple addresses so we need to "weigh"
the rate limit more heavily the more emails are submitted. Clearly e.g.
a request triggering emails to 2 addresses should weigh twice as much as
a request doing that for just 1 address.
This allows for greater flexibility in values for "environment," and
avoids having to have duplicate definitions of STAGING in
`zproject/config.py` and `zproject/default_settings.py` (due to import
order restrictions).
It does overload the "deploy type" concept somewhat.
Follow-up to #19185.
If the user is logged in, we'll stick to rate limiting by the
UserProfile. In case of requests without authentication, we'll apply the
same limits but to the IP address.
Rename poll_timeout to event_queue_longpoll_timeout_seconds
and change its value from 90000 ms to 90 sec. Expose its
value in register api response when realm data is fetched.
Bump API_FEATURE_LEVEL to 74.
This adds basic support for `postgresql.database_user` and
`postgresql.database_name` settings in `zulip.conf`; the defaults if
unspecified are left as `zulip`.

This makes it parallel with deliver_scheduled_messages, and clarifies
that it is not used for simply sending outgoing emails (e.g. the
`email_senders` queue).
This also renames the supervisor job to match.
Thumbor and tc-aws have been dragging their feet on Python 3 support
for years, and even the alphas and unofficial forks we’ve been running
don’t seem to be maintained anymore. Depending on these projects is
no longer viable for us.

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.
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.

The `X-Forwarded-For` header is a list of proxies' IP addresses; each
proxy appends the remote address of the host it received its request
from to the list, as it passes the request down. A naïve parsing, as
SetRemoteAddrFromForwardedFor did, would thus interpret the first
address in the list as the client's IP.
However, clients can pass in arbitrary `X-Forwarded-For` headers,
which would allow them to spoof their IP address. `nginx`'s behavior
is to treat the addresses as untrusted unless they match an allowlist
of known proxies. By setting `real_ip_recursive on`, it also allows
this behavior to be applied repeatedly, moving from right to left down
the `X-Forwarded-For` list, stopping at the right-most that is
untrusted.
Rather than re-implement this logic in Django, pass the first
untrusted value that `nginx` computer down into Django via `X-Real-Ip`
header. This allows consistent IP addresses in logs between `nginx`
and Django.
Proxied calls into Tornado (which don't use UWSGI) already passed this
header, as Tornado logging respects it.
This adds the is_user_active with the appropriate code for setting the
value correctly in the future. In the following commit a migration to
backfill the value for existing Subscriptions will be added.
To ensure correct user_profile.is_active handling also in tests, we
replace all direct .is_active mutation with calls to appropriate
functions.

- django.contrib.postgres.fields.JSONField is deprecated and should be
replaced with models.JSONField
- The internals of the implementation in the postgresql backend have
changed a bit in
f48f671223
and thus we need to make an ugly tweak in test_runner.
- app_directories.Loader.get_dirs() now returns a list of PosixPath so
we need to make a small tweak in TwoFactorLoader for that (PosixPath
is not iterable)
Fixes#16010.
Boto3 does not allow setting the endpoint url from
the config file. Thus we create a django setting
variable (`S3_ENDPOINT_URL`) which is passed to
service clients and resources of `boto3.Session`.
We also update the uploads-backend documentation
and remove the config environment variable as now
AWS supports the SIGv4 signature format by default.
And the region name is passed as a parameter instead
of creating a config file for just this value.
Fixes#16246.
