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.

This is be useful for the mobile and desktop apps to hand an uploaded
file off to the system browser so that it can render PDFs (Etc.).
The S3 backend implementation is simple; for the local upload backend,
we use Django's signing feature to simulate the same sort of 60-second
lifetime token.

URLs for config errors were configured seperately for each error
which is better handled by having error name as argument in URL.
A new view `config_error_view` is added containing context for
each error that returns `config_error` page with the relevant
context.
Also fixed tests and some views in `auth.py` to be consistent with
changes.
We had a bunch of ugly hacks to monkey patch things due to upstream
being temporarily unmaintained and not merging PRs. Now the project is
active again and the fixes have been merged and included in the latest
version - so we clean up all that code.
Extend the context dictionary with variables `social_backend_name`
and `backend_error` flag which determines if the error should be
shown. Not extended this for ldap, smtp and saml as they have a
different format of block.
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* urls: django.urls.resolvers.RegexURLPattern has been replaced by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.
Since essentially the first use of Tornado in Zulip, we've been
maintaining our Tornado+Django system, AsyncDjangoHandler, with
several hundred lines of Django code copied into it.
The goal for that code was simple: We wanted a way to use our Django
middleware (for code sharing reasons) inside a Tornado process (since
we wanted to use Tornado for our async events system).
As part of the Django 2.2.x upgrade, I looked at upgrading this
implementation to be based off modern Django, and it's definitely
possible to do that:
* Continue forking load_middleware to save response middleware.
* Continue manually running the Django response middleware.
* Continue working out a hack involving copying all of _get_response
to change a couple lines allowing us our Tornado code to not
actually return the Django HttpResponse so we can long-poll. The
previous hack of returning None stopped being viable with the Django 2.2
MiddlewareMixin.__call__ implementation.
But I decided to take this opportunity to look at trying to avoid
copying material Django code, and there is a way to do it:
* Replace RespondAsynchronously with a response.asynchronous attribute
on the HttpResponse; this allows Django to run its normal plumbing
happily in a way that should be stable over time, and then we
proceed to discard the response inside the Tornado `get()` method to
implement long-polling. (Better yet might be raising an
exception?). This lets us eliminate maintaining a patched copy of
_get_response.
* Removing the @asynchronous decorator, which didn't add anything now
that we only have one API endpoint backend (with two frontend call
points) that could call into this. Combined with the last bullet,
this lets us remove a significant hack from our
never_cache_responses function.
* Calling the normal Django `get_response` method from zulip_finish
after creating a duplicate request to process, rather than writing
totally custom code to do that. This lets us eliminate maintaining
a patched copy of Django's load_middleware.
* Adding detailed comments explaining how this is supposed to work,
what problems we encounter, and how we solve various problems, which
is critical to being able to modify this code in the future.
A key advantage of these changes is that the exact same code should
work on Django 1.11, Django 2.2, and Django 3.x, because we're no
longer copying large blocks of core Django code and thus should be
much less vulnerable to refactors.
There may be a modest performance downside, in that we now run both
request and response middleware twice when longpolling (once for the
request we discard). We may be able to avoid the expensive part of
it, Zulip's own request/response middleware, with a bit of additional
custom code to save work for requests where we're planning to discard
the response. Profiling will be important to understanding what's
worth doing here.
This adds a new API endpoint for querying basic data on a single other
user in the organization, reusing the existing infrastructure (and
view function!) for getting data on all users in an organization.
Fixes#12277.
Tests require adjusting, because the class-based view has an additional
redirect - through /uid/set-password/ and the token is read from the
session. See Django code of PasswordResetConfirmView.
The original/legacy emoji reactions endpoints made use of HTTP PUT and
didn't have an API that could correctly handle situations where the
emoji names change over time. We stopped using the legacy endpoints
some time ago, so we can remove them now.
This requires straightforward updates to older tests that were still
written against the legacy API.
Fixes#12940.
Needed so that the google entry in social_backends in /server_settings
shows the new url rather than the legacy accounts/login/google/ url as
the login url.
This legacy endpoint was designed for the original native Zulip mobile
apps, which were deprecated years ago in favor of the React Native
app.
It was replaced by /server_settings for active use years ago, so it's
safe to remove it now.
The url scheme is now /accounts/login/social/saml/{idp_name} to initiate
login using the IdP configured under "idp_name" name.
display_name and display_logo (the name and icon to show on the "Log in
with" button) can be customized by adding the apprioprate settings in
the configured IdP dictionaries.
There are a few outstanding issues that we expect to resolve beforce
including this in a release, but this is good checkpoint to merge.
This PR is a collaboration with Tim Abbott.
Fixes#716.
Previously, several of our URL patterns accidentally did not end with
`$`, and thus ended up controlling just the stated URL, but actually a
much broader set of URLs starting with it.
I did an audit and fixed what I believe are all instances of this URL
pattern behavior. In the process, I fixed a few tests that were
unintentionally relying on the behavior.
Fixes#13082.
In bf14a0af4, we refactored the Google authentication system to use
the same code as GitHub auth, but neglected to provide a
backwards-compatible URL available for use by older versions of the
mobile apps.
Fixes#13081.
This restructures the API endpoints that we currently have implemented
more or less for exclusive use by the mobile and desktop apps (things
like checking what authentication methods are supported) to use a
system that can be effectively parsed by our test_openapi
documentation.
This brings us close to being able to eliminate
`buggy_documentation_endpoints` as a persistently nonempty list.
This feature is intended to cover all of our ways of exporting a
realm, not just the initial "public export" feature, so we should name
things appropriately for that goal.
Additionally, we don't want to include data exports in page_params;
the original implementation was actually buggy and would have.
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.
In each url of urls.py, if we want to mark an endpoint as being
intentionally undocumented, then in the kwargs instead of directly
mapping like 'METHOD': 'zerver.views.package.foo', we can provide
a tag called 'intentionally_undocumented' and map like:
'METHOD': ('zerver.views.package.foo', {'intentionally_undocumented'}).
If an endpoint is marked as intentionally undocumented, but we find
some OpenAPI documentation for it then we'll throw an error, in which
case either the 'intentionally_undocumented' tag should be removed or
the faulty documentation should be removed.
This will allow us to mark a REQ variable as intentionally
undocumented. With this, we can remove some of the endpoints marked
as "buggy" even though they're not actually buggy, we just needed to
specify certain parameters as intentionally undocumented (e.g. the
stream_id for the /users/me/subscriptions/muted_topics endpoint.)
Any REQ variable with intentionally_undocumentated set to True
will not be added to the arguments_map data structure.
For some of the other "buggy" endpoints, we would want to mark the
entire endpoint as being undocumented intentionally via. the urls.py
file.
The github-services model for how GitHub would send requests to this
legacy integration is no longer available since earlier in 2019.
Removing this integration also allows us to finally remove
authenticated_api_view, the legacy authentication model from 2013 that
had been used for this integration (and other features long since
upgraded).
A few functions that were used by the Beanstalk webhook are moved into
that webhook's implementation directly.
An endpoint was created in zerver/views. Basic rate-limiting was
implemented using RealmAuditLog. The idea here is to simply log each
export event as a realm_exported event. The number of events
occurring in the time delta is checked to ensure that the weekly
limit is not exceeded.
The event is published to the 'deferred_work' queue processor to
prevent the export process from being killed after 60s.
Upon completion of the export the realm admin(s) are notified.
Previously, we had some expensive-to-calculate keys in
zulip_default_context, especially around enabled authentication
backends, which in total were a significant contributor to the
performance of various logged-out pages. Now, these keys are only
computed for the login/registration pages where they are needed.
This is a moderate performance optimization for the loading time of
many logged-out pages.
Closes#11929.
