Anders Kaseorg edf411718c openapi: Fix documentation of narrow parameter.
The narrow parameter was incorrectly documented as a one-level array
rather than an array of arrays, and the tests incorrectly expected
this due to a combination of design and implementation bugs.

Anders Kaseorg 91a86c24f5 python: Replace None defaults with empty collections where appropriate.
Use read-only types (List ↦ Sequence, Dict ↦ Mapping, Set ↦

Anders Kaseorg 69c0959f34 python: Fix misuse of Optional types for optional parameters.
There seems to have been a confusion between two different uses of the
word “optional”:

• An optional parameter may be omitted and replaced with a default
  value.
• An Optional type has None as a possible value.

Sometimes an optional parameter has a default value of None, or None
is otherwise a meaningful value to provide, in which case it makes
sense for the optional parameter to have an Optional type.  But in
other cases, optional parameters should not have Optional type.  Fix
them.

Steve Howell 09f5090d1f test: Simplify test_multi_user_subscription.
We triage on the event's "op" field instead
of using the type check.

And then we still get the implicit assertion
that we any "add" event produces a dict
for "subscriptions", since we dereference it
in the assertion for "subscribers".

Anders Kaseorg 365fe0b3d5 python: Sort imports with isort.
Fixes #2665.

Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.

Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start.  I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

Graham Bleaney 461d5b1a3e pysa: Introduce sanitizers, models, and inline marking safe.
This commit adds three `.pysa` model files: `false_positives.pysa`
for ruling out false positive flows with `Sanitize` annotations,
`req_lib.pysa` for educating pysa about Zulip's `REQ()` pattern for
extracting user input, and `redirects.pysa` for capturing the risk
of open redirects within Zulip code. Additionally, this commit
introduces `mark_sanitized`, an identity function which can be used
to selectively clear taint in cases where `Sanitize` models will not
work. This commit also puts `mark_sanitized` to work removing known
false postive flows.

Kartik Srivastava 8c39ddfd28 api: Add GET /users/{user_id}/subscription/{stream_id} endpoint.
This new endpoint returns a 'user' dictionary which, as of now,
contains a single key 'is_subscribed' with a boolean value that
represents whether the user with the given 'user_id' is subscribed
to the stream with the given 'stream_id'.

Fixes #14966.

Steve Howell d5cc29755e typing: Accept only user_ids in typing endpoint.
The only clients that should use the typing
indicators endpoint are our internal clients,
and they should send a JSON-formatted list
of user_ids.

We now enforce this, which removes some
complexity surrounding legacy ways of sending
users, such as emails and comma-delimited
strings of user_ids.

There may be a very tiny number of mobile
clients that still use the old emails API.

This won't have any user-facing effect on
the mobile users themselves, but if you type
a message to your friend on an old mobile
app, the friend will no longer see typing
indicators.

Also, the mobile team may see some errors
in their Sentry logs from the server rejecting
posts from the old mobile clients.

The error messages we report here are a bit
more generic, since we now just use REQ
to do validation with this code:

    validator=check_list(check_int)

This also allows us to remove a test hack
related to the API documentation.  (We changed
the docs to reflect the modern API in an
earlier commit, but the tests couldn't be
fixed while we still had the more complex
semantics for the "to" parameter.)

orientor e989c87a18 openapi: Fix response validation bug.
Currently there are no checks in validate_against_openapi_schema
to check whether the `content` it received actually matched with
the `response code`. For example during testing if a certain endpoint
was returning 400 but it was expected to return 200, then it would
pass schema validation as it would only have `msg` and `result` keys.
Add this validation and fix the wrong response returning points.

Hemanth V. Alluri 7b2255597c outgoing-webhook: Fix check for empty content.
Prevent `JsonableError(_("Missing content"))` from
ever being triggered.

That error wasn't handle by anything, and thus just threw a 500, as
it's not a response to an HTTP request.

The right fix is to adjust the caller to ban the empty string in
content (or content that strips to the empty string).

Closes #15145.

Dinesh 0c45e0118f tests: Clear remove/remock approach for ACCESS_TOKEN_URL endpoint.
ACCESS_TOKEN_URL works a different for apple authentication, so,
we removed and remocked the ACCESS_TOKEN_URL mock in
`register_extra_endpoints` override of apple auth test class.
It is cleaner to have it as generic feature of `social_auth_test`.

So, this commit adds a function that returns token_data_dict that
we had earlier and is called in the ACCESS_TOKEN_URL mock.
This function is overriden in apple auth test class to generate
payload of the format that apple auth expects.

Thanks to Mateusz Mandera for the simple idea.

sahil839 6d667dbe53 realm owner: Add ability to change realm owner status of user.
This commit adds some basic checks while adding or removing
realm owner status of a user and adds code to change owner
status of a user using update_user_backend.

This also adds restriction on removing owner status of the
last owner of realm. This restriction was previously on
revoking admin status, but as we have added a more privileged
role of realm owner, we now have this restriction on owner
instead of admin.

We need to apply that restriction both in the role change code path
and the deactivate code path.

This was implemented in 2012 to avoid showing a loading indicator for

Dinesh d30f11888a logging: Set up a different logger for each backend.
Adds a top-level logger in `settings.LOGGING` `zulip.auth`
with the default handlers `DEFAULT_ZULIP_HANDLERS` and
an extra hanlder that writes to `/var/log/zulip/auth.log`.

Each auth backend uses it's own logger, `self.logger` which
is in form 'zulip.auth.<backend name>'.

This way it's clear which auth backend generated the log
and is easier to look for all authentication logs in one file.

Besides the above mentioned changes, `name` attribute is added to
`ZulipAuthMixin` so that these logging kind of calls wouldn't raise
any issues when logging is tried in a class without `name` attribute.

Also in the tests we use a new way to check if logger calls are made
i.e. we use `assertLogs` to test if something is logged.

Thanks to Mateusz Mandera for the idea of having a seperate logger
for auth backends and suggestion of using `assertLogs`.
