Anders Kaseorg 8e4f22c184 auth: Require algorithms setting for JWT auth.
Calling jwt.decode without an algorithms list raises a
DeprecationWarning.  This is for protecting against
symmetric/asymmetric key confusion attacks.

This is a backwards-incompatible configuration change.

Fixes #15207.

Anders Kaseorg 4d04fa3118 compose: Rewrite Zoom video call integration to use OAuth.
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.

We change do_create_user and create_user to accept
role as a parameter instead of 'is_realm_admin' and 'is_guest'.
These changes are done to minimize data conversions between
role and boolean fields.

Earlier this `standard_relay_params` was used only for SAML auth,

in session for reuse. So, this acts as a prep commit for "Sign in
with Apple" auth support.

Mateusz Mandera 13c3eaf086 rate_limit: Restrict tornado backend to explicitly specified domains.
This will protect us in case of some kinds of bugs that could allow
making requests such as password authentication attempts to tornado.
Without restricting the domains to which the in-memory backend can
be applied, such bugs would lead to attackers having multiple times
larger rate limits for these sensitive requests.

Dinesh 288921d425 auth: Log when a user tries to login with deactivated account.
Helps to see if users are often trying to login with deactived
accounts.
A use case: Trackdown whether any deactivated bot users are still
trying to access the API.

This implementation adds a new key `inactive_user_id`
to `return_data` in the function `is_user_active` which
check if a `user_profile` is active. This reduces the effort
of getting `user_id` just before logging.

Modified tests for line coverage.

Mateusz Mandera dac4a7a70b saml: Figure out the idp from SAMLResponse.
Instead of plumbing the idp to /complete/saml/ through redis, it's much
more natural to just figure it out from the SAMLResponse, because the
information is there.
This is also a preparatory step for adding IdP-initiated sign in, for
which it is important for /complete/saml/ to be able to figure out which
IdP the request is coming from.

Mateusz Mandera 2f5fd272aa auth: Gracefully handle bad http responses from IdP in social auth.

bad http responses, which will raise HTTPError inside

in those cases, but simply log the exception and fail gracefully.

Mateusz Mandera dd40649e04 queue_processors: Remove the slow_queries queue.
While this functionality to post slow queries to a Zulip stream was
very useful in the early days of Zulip, when there were only a few
hundred accounts, it's long since been useless since (1) the total
request volume on larger Zulip servers run by Zulip developers, and
(2) other server operators don't want real-time notifications of slow
backend queries.  The right structure for this is just a log file.

We get rid of the queue and replace it with a "zulip.slow_queries"
logger, which will still log to /var/log/zulip/slow_queries.log for
ease of access to this information and propagate to the other logging
handlers.  Reducing the amount of queues is good for lowering zulip's
memory footprint and restart performance, since we run at least one
dedicated queue worker process for each one in most configurations.

Tim Abbott e29d1fc776 settings: Clean up pika logging.
It appears that a recent pika release started logging spammy INFO
output on the pika.connection and pika.channel channels, in addition
to the existing pika.adapters channel.

It's probably best to just move to WARNING-level logging for all of these.

This significantly cleans up the output when run-dev.py restarts
services due to a code change in the development environment.

Dinesh a3329f288c auth: Modify `filter_usable_emails` to only exclude noreply github emails.
Instead of having to filter `@noreply.github.com` emails in
`get_unverified_emails`, it's good to make `filter_usable_emails`
just filter `@noreply.github.com` and handle verified/unverified
part in their respective functions because of `@noreply.github.com`
exception being a fiddly special-case detail.
Also renamed `filter_usable_emails` to `get_usable_email_objects`
as a line that gets all associated github emails is removed in
`get_verified_emails` and `get_unverified_emails` and added to
`filter_usable_emails`. The name `filter_usable_emails` suggests
that it just filters given emails, whereas here it's getting all
associated email objects and returning usable emails.

This commit extends the template for "choose email" to mention for
users who have unverified emails that they need to verify them before
using them for Zulip authentication.

Also modified `social_auth_test_finish` to assert if all emails
are present in "choose email" screen as we need unverified emails
to be shown to user and verified emails to login/signup.

Mateusz Mandera f1ec02b40a auth: Add ExternalAuthResult to manage data in authentication flows.
This new type eliminates a bunch of messy code that previously
involved passing around long lists of mixed positional keyword and
arguments, instead using a consistent data object for communicating
about the state of an external authentication (constructed in
backends.py).

The result is a significantly more readable interface between
zproject/backends.py and zerver/views/auth.py, though likely more
could be done.

This has the side effect of renaming fields for internally passed
structures from name->full_name, next->redirect_to; this results in
most of the test codebase changes.

Modified by tabbott to add comments and collaboratively rewrite the
initialization logic.

Steve Howell e47e1cd648 droplet settings: Fix hostname-related settings.
We recently changed our droplet setup such that their
host names no longer include zulipdev.org.  This caused
a few things to break.

The particular symptom that this commit fixes is that
we were trying to server static assets from
showell:9991 instead of showell.zulipdev.org:9991,
which meant that you couldn't use the app locally.
(The server would start, but the site's pretty unusable
without static assets.)

Now we rely 100% on `dev_settings.py` to set
`EXTERNAL_HOST` for any droplet users who don't set
that var in their own environment.  That allows us to
remove some essentially duplicate code in `run-dev.py`.

We also set `IS_DEV_DROPLET` explicitly, so that other
code doesn't have to make inferences or duplicate
logic to detemine whether we're a droplet or not.

And then in `settings.py` we use `IS_DEV_DROPLET` to
know that we can use a prod-like method of calculating
`STATIC_URL`, instead of hard coding `localhost`.

We may want to iterate on this further--this was
sort of a quick fix to get droplets functional again.
It's possible we can re-configure droplets to have
folks get reasonable `EXTERNAL_HOST` settings in their
bash profiles, or something like that, although that
may have its own tradeoffs.
