Uses git release as this version 3.4.0 is not released to pypi.
This is required for removing some overriden functions of
apple auth backend class AppleAuthBackend.
With the update we also make following changes:
* Fix full name being populated as "None None".
c5c74f27dd that's included in update assigns first_name and last_name
to None when no name is provided by apple. Due to this our
code is filling return_data['full_name'] to 'None None'.
This commit fixes it by making first and last name strings empty.
* Remove decode_id_token override.
Python social auth merged the PR we sent including the changes
we made to decode_id_token function. So, now there is no
necessity for the override.
* Add _AUDIENCE setting in computed_settings.py.
`decode_id_token` is dependent on this setting.
Our previous OpenAPI schema validator that we implemented ourselves
was useful training wheels for our understanding OpenAPI properly, and
was mostly correct. But given that we've finally reached the point
where our OpenAPI file accurately describes the API, it makes sense to
switch to use an official OpenAPI validator. We lose some ability to
do exclude rules for particular elements, but those were primarily
important for us when we had a lot of them.
As part of this change, we need to add `additionalProperties: false`
for all of our dictonaries/objects where we've documented every
parameter; otherwise the OpenAPI schema checker won't know that we
expect every parameter to be documented.
This reimplements our Zoom video call integration to use an OAuth
application. In addition to providing a cleaner setup experience,
especially on zulipchat.com where the server administrators can have
done the app registration already, it also fixes the limitation of the
previous integration that it could only have one call active at a time
when set up with typical Zoom API keys.
Fixes#11672.

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.

This does not rely on the desktop app being able to register for the
zulip:// scheme (which is problematic with, for example, the AppImage
format).
It also is a better interface for managing changes to the system,
since the implementation exists almost entirely in the server/webapp
project.
This provides a smoother user experience, where the user doesn't need
to do the paste step, when combined with
https://github.com/zulip/zulip-desktop/pull/943.

Includes this change:
* openapi/python_examples: Update get_single_user.
This updates get_single_user to pass keyword arguments to
get_user_by_id instead of passing a dictionary.
Which is required for CI to pass, as we indeed fixed the API of that
function (which had only been present with the wrong API for one release).

Upgrade libthumbor in main zulip venv. This version drops support
for python 2 and runs on py>=3.6.
As such, it is our first commit taking advantage of our having dropped support
for Debian Stretch and Ubuntu Xenial, our previous Python 3.5-based platforms.
For upgrade-zulip-from-git to work, we need to be able to run
update-prod-static on production systems, which means provision code
like this cairosvg logic needs to be there for now.
python 3.8 support for python-api-bindings was fixed in commit
63bc9b8a4f
so upgraded python-api-bindings to tag 0.6.3 which included this fix.
Bumped PROVISION_VERSION.
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.
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.

For a long time, we've been only doing the zxcvbn password strength
checks on the browser, which is helpful, but means users could through
hackery (or a bug in the frontend validation code) manage to set a
too-weak password. We fix this by running our password strength
validation on the backend as well, using python-zxcvbn.
In theory, a bug in python-zxcvbn could result in it producing a
different opinion than the frontend version; if so, it'd be a pretty
bad bug in the library, and hopefully we'd hear about it from users,
report upstream, and get it fixed that way. Alternatively, we can
switch to shelling out to node like we do for KaTeX.
Fixes#6880.
Send the `csrftoken` and `sessionid` cookies with `SameSite=Lax`.
This adds a layer of defense against CSRF attacks and matches the new
default in Django 2.1:
https://docs.djangoproject.com/en/2.1/releases/2.1/#samesite-cookies
This can be reverted when we upgrade to Django ≥ 2.1.

This makes no changes to the locked versions in *.txt, but it reduces

to *.in with an explanatory comment.

We already had this as an indirect dependency, but now it's going to be
needed to write a decorator for rate limiting authenticate() functions,
so it should be added to common.in.
Fixes#11209.
This requires changing how zadd is used in rate_limiter.py:
In redis-py >= 3.0 the pairs to ZADD need to be passed as a dictionary,
not as *args or **kwargs, as described at
https://pypi.org/project/redis/3.2.1/ in the section
"Upgrading from redis-py 2.X to 3.0".
The rate_limiter change has to be in one commit with the redis upgrade,
because the dict format is not supported before redis-py 3.0.
This replaces the two custom Google authentication backends originally
written in 2012 with using the shared python-social-auth codebase that
we already use for the GitHub authentication backend. These are:
* GoogleMobileOauth2Backend, the ancient code path for mobile
authentication last used by the EOL original Zulip Android app.
* The `finish_google_oauth2` code path in zerver/views/auth.py, which
was the webapp (and modern mobile app) Google authentication code
path.
This change doesn't fix any known bugs; its main benefit is that we
get to remove hundreds of lines of security-sensitive semi-duplicated
code, replacing it with a widely trusted, high quality third-party
library.
If a url doesn't have a scheme, browsers would treat it as a relative
url and open something like: https://chat.zulip.org/google.com instead.
This PR fixes the issue on the backend; the frontend implementation
remains out of sync and the user sending the message wouldn't see
any linkification for urls without a scheme.
Fixes#12791.

Reverts c09962b and 697b4b2. The lines that break look like

Something like stripe_invoice.finalize_invoice() would work, but it's a big
change given how the tests in test_stripe.py currently work.
This is required for Python 3.7 support; line_profiler needs a release
with Cython rerun following the Python 3.7 release, and this achieves
that goal.
This commit leverages the ahocorasick algorithm to build a set of user_ids
that have their alert_words present in the message. It runs in linear time
of the order of length of the input message as opposed to number of
alert_words. This is after building a ahocorasick Automaton which runs
in O(number of alert_words in entire realm) which is usually cached.
This is a major upgrade, and requires some significant compatibility
work:
* Migrating the pattern-removal logic to use the Registry feature.
* Handling the removal of positional arguments in markdown extensions.
* Handling the removal of safe mode.
Now, if you pass an api_key, we'll initialize the public room
subscribers to be whatever they were at the time the import happened.
Also, document the situation on the caveats section.
