Zixuan James Li 6201914fd3 message_edit: Migrate message_edit to use @typed_endpoint.
This demonstrates how an alias is created and its suitable use case, the
use of PathOnly, NonNegativeInt, and Literal.

Zixuan James Li 9c53995830 alert_words: Migrate alert_words to use @typed_endpoint.
This demonstrates some basic use cases of the Json[...] wrapper with
@typed_endpoint.

Along with this change we extend test_openapi so that schema checking
based on function signatures will still work with this new decorator.
Pydantic's TypeAdapter supports dumping the JSON schema of any given type,
which is leveraged here to validate against our own OpenAPI definitions.
Parts of the implementation will be covered in later commits as we
migrate more functions to use @typed_endpoint.

See also:
https://docs.pydantic.dev/latest/api/type_adapter/#pydantic.type_adapter.TypeAdapter.json_schema

For the OpenAPI schema, we preprocess it mostly the same way. For the
parameter types though, we no longer need to use
get_standardized_argument_type to normalize type annotation, because
Pydantic dumps a JSON schema that is compliant with OpenAPI schema
already, which makes it a lot convenient for us to compare the types
with our OpenAPI definitions.

Do note that there are some exceptions where our definitions do not match
the generated one. For example, we use JSON to parse int and bool parameters,
but we don't mark them to use "application/json" in our definitions.

This is important because the "guests" value isn't one that we'd

Lauryn Menard 91b40a45fe demo-orgs: Add email and password process for demo organization owners.
Creates process for demo organization owners to add an email address
and password to their account.

Uses the same flow as changing an email (via user settings) at the
beginning, but then sends a different email template to the user
for the email confirmation process.

We also encourage users to set their full name field in the modal for
adding an email in a demo organization. We disable the submit button
on the form if either input is empty, email or full name.

When the user clicks the 'confirm and set password' button in the
email sent to confirm the email address sent via the form, their
email is updated via confirm_email_change, but the user is redirected
to the reset password page for their account (instead of the page for
confirming an email change has happened).

Once the user successfully sets a password, then they will be
prompted to log in with their newly configured email and password.

Lauryn Menard a9eb70ac68 demo-orgs: Set owner `email_address_visibility` on account creation.
Since an email address is not required to create a demo organization,
we need a Zulip API email address for the web-app to use until the
owner configures an email for their account.

Here, we set the owner's `email_address_visibility` to "Nobody" when
the owner's account is created so that the Zulip API email field in
their profile is a fake email address string.

Eeshan Garg 5e33ae8adf demo-orgs: Create dev environment demo organization without email.
To make creation of demo organizations feel lightweight for users,
we do not want to require an email address at sign-up. Instead an
empty string will used for the new realm owner's email. Currently
implements that for new demo organizations in the development
environment.

Because the user's email address does not exist, we don't enqueue
any of the welcome emails upon account/realm creation, and we
don't create/send new login emails.

This is a part of #19523.

Lauryn Menard ebfe9637c8 subscribe-unsubscribe: Improve error response for unexpected users.
Updates the API error response when there is an unknown or
deactivated user in the `principals` parameter for either the
`/api/subscribe` or `/api/unsubscribe` endpoints. We now use
the `access_user_by_email` and `access_user_by_id` code paths,
which return an HTTP response of 400 and a "BAD_REQUEST" code.

Previously, an HTTP response of 403 was returned with a special
"UNAUTHORIZED_PRINCIPAL" code in the error response. This code
was not documented in the API documentation and is removed as
a potential JsonableError code with these changes.

Fixes #26593.

Danny Su 66b9c06de6 compose: Add support for Zoom audio call
This PR implements the audio call feature for Zoom. This is done by explicitly
telling Zoom to create a meeting where the host's video and participants' video
are off by default.

Another key change is that when creating a video call, the host's and
participants' video will be on by default. The old code doesn't specify that
setting, so meetings actually start with video being off. This new behavior has
less work for users to do. They don't have to turn on video when joining a call
advertised as "video call". It still respects users' preferences because they
can still configure their own personal setting that overrides the meeting
defaults.

The Zoom API documentation can be found at
https://developers.zoom.us/docs/api/rest/reference/zoom-api/methods/#operation/meetingCreate

Fixes #26549.

Zixuan James Li a081428ad2 user_groups: Make locks required for updating user group memberships.
**Background**

User groups are expected to comply with the DAG constraint for the
many-to-many inter-group membership. The check for this constraint has
to be performed recursively so that we can find all direct and indirect
subgroups of the user group to be added.

This kind of check is vulnerable to phantom reads which is possible at
the default read committed isolation level because we cannot guarantee
that the check is still valid when we are adding the subgroups to the
user group.

**Solution**

To avoid having another transaction concurrently update one of the
to-be-subgroup after the recursive check is done, and before the subgroup
is added, we use SELECT FOR UPDATE to lock the user group rows.

The lock needs to be acquired before a group membership change is about
to occur before any check has been conducted.

Suppose that we are adding subgroup B to supergroup A, the locking protocol
is specified as follows:

1. Acquire a lock for B and all its direct and indirect subgroups.
2. Acquire a lock for A.

For the removal of user groups, we acquire a lock for the user group to
be removed with all its direct and indirect subgroups. This is the special
case A=B, which is still complaint with the protocol.

**Error handling**

We currently rely on Postgres' deadlock detection to abort transactions
and show an error for the users. In the future, we might need some
recovery mechanism or at least better error handling.

**Notes**

An important note is that we need to reuse the recursive CTE query that
finds the direct and indirect subgroups when applying the lock on the
rows. And the lock needs to be acquired the same way for the addition and
removal of direct subgroups.

User membership change (as opposed to user group membership) is not
affected. Read-only queries aren't either. The locks only protect
critical regions where the user group dependency graph might violate
the DAG constraint, where users are not participating.

**Testing**

We implement a transaction test case targeting some typical scenarios
when an internal server error is expected to happen (this means that the
user group view makes the correct decision to abort the transaction when
something goes wrong with locks).

To achieve this, we add a development view intended only for unit tests.
It has a global BARRIER that can be shared across threads, so that we
can synchronize them to consistently reproduce certain potential race
conditions prevented by the database locks.

The transaction test case lanuches pairs of threads initiating possibly
conflicting requests at the same time. The tests are set up such that exactly N
of them are expected to succeed with a certain error message (while we don't
know each one).

**Security notes**

get_recursive_subgroups_for_groups will no longer fetch user groups from
other realms. As a result, trying to add/remove a subgroup from another
realm results in a UserGroup not found error response.

We also implement subgroup-specific checks in has_user_group_access to
keep permission managing in a single place. Do note that the API
currently don't have a way to violate that check because we are only
checking the realm ID now.

Zixuan James Li a3f4341934 user_groups: Make for_read required.

Sahil Batra 7295028194 message: Access realm object directly from message.
We can directly get the realm object from Message object now
and there is no need to get the realm object from "sender"
field of Message object.

After this change, we would not need to fetch "sender__realm"
field using "select_related" and instead only passing "realm"
to select_related when querying Message objects would be enough.

This commit also updates a couple of cases to directly access
realm ID from message object and not message.sender. Although
we have fetched sender object already, so accessing realm_id
from message directly or from message.sender should not matter,
but we can be consistent to directly get realm from Message
object whenever possible.

Zixuan James Li 30495cec58 migration: Rename extra_data_json to extra_data in audit log models.
This migration applies under the assumption that extra_data_json has
been populated for all existing and coming audit log entries.

- This removes the manual conversions back and forth for extra_data
throughout the codebase including the orjson.loads(), orjson.dumps(),
and str() calls.

- The custom handler used for converting Decimal is removed since
DjangoJSONEncoder handles that for extra_data.

- We remove None-checks for extra_data because it is now no longer
nullable.

- Meanwhile, we want the bouncer to support processing RealmAuditLog entries for
remote servers before and after the JSONField migration on extra_data.

- Since now extra_data should always be a dict for the newer remote
server, which is now migrated, the test cases are updated to create
RealmAuditLog objects by passing a dict for extra_data before
sending over the analytics data. Note that while JSONField allows for
non-dict values, a proper remote server always passes a dict for
extra_data.

- We still test out the legacy extra_data format because not all
remote servers have migrated to use JSONField extra_data.
This verifies that support for extra_data being a string or None has not
been dropped.

Akshat baede93f69 narrow: Fix topic highlighting issue with apostrophes in search results.
This commit addresses the issue where the topic highlighting
in search results was offset by one character when an
apostrophe was present. The problem stemmed from the disparity
in HTML escaping generated by the function `func.escape_html` which
is used to obtain `topic_matches` differs from the escaping performed
by the function `django.utils.html.escape` for apostrophes (').

func.escape_html | django.utils.html.escape
-----------------+--------------------------
      &#39;      |           &#x27;

To fix this SQL query is changed to return the HTML-escaped
topic name generated by the function `func.escape_html`.

Zixuan James Li 37660dd0e7 linkifier: Support reordering linkifiers.
This adds API support to reorder linkifiers and makes sure that the
returned lists of linkifiers from `GET /events`, `POST /register`, and
`GET /realm/linkifiers` are always sorted with the order that they
should processed when rendering linkifiers.

We set the new `order` field to the ID with the migration. This
preserves the order of the existing linkifiers.

New linkifiers added will always be ordered the last. When reordering,
the `order` field of all linkifiers in the same realm is updated, in
a manner similar to how we implement ordering for
`custom_profile_fields`.

Steve Howell 51db22c86c per-request caches: Add per_request_cache library.
We have historically cached two types of values
on a per-request basis inside of memory:

    * linkifiers
    * display recipients

Both of these caches were hand-written, and they
both actually cache values that are also in memcached,
so the per-request cache essentially only saves us
from a few memcached hits.

I think the linkifier per-request cache is a necessary
evil. It's an important part of message rendering, and
it's not super easy to structure the code to just get
a single value up front and pass it down the stack.

I'm not so sure we even need the display recipient
per-request cache any more, as we are generally pretty
smart now about hydrating recipient data in terms of
how the code is organized. But I haven't done thorough
research on that hypotheseis.

Fortunately, it's not rocket science to just write
a glorified memoize decorator and tie it into key
places in the code:

    * middleware
    * tests (e.g. asserting db counts)
    * queue processors

That's what I did in this commit.

This commit definitely reduces the amount of code
to maintain. I think it also gets us closer to
possibly phasing out this whole technique, but that
effort is beyond the scope of this PR. We could
add some instrumentation to the decorator to see
how often we get a non-trivial number of saved
round trips to memcached.

Note that when we flush linkifiers, we just use
a big hammer and flush the entire per-request
cache for linkifiers, since there is only ever
one realm in the cache.

Sahil Batra ae72151ec1 streams: Pass stream_weekly_traffic field in stream objects.
This commit adds code to pass stream traffic data using
the "stream_weekly_traffic" field in stream objects.

We already include the traffic data in Subscription objects,
but the traffic data does not depend on the user to stream
relationship and is stream-only information, so it's better
to include it in Stream objects. We may remove the traffic
data and other stream information fields for Subscription
objects in future.

This will help clients to correctly display the stream
traffic data in case where client receives a stream
creation event and no subscription event, for an already

Realm object when realm_id sufficed, and returned a
tuple of strings that had different semantics.

I also avoid calling it duplicate times in a couple
places, although it was probably rarely the case that
both invocations actually happened if upstream
validations were working.

Note that there is a TypedDict called EmojiInfo, so I
chose EmojiData here.  Perhaps a better name would be
TinyEmojiData or something.

I also simplify the reaction tests with a verify
helper.

Steve Howell b742f1241f realm emoji: Use a single cache for all lookups.
The active realm emoji are just a subset of all your
realm emoji, so just use a single cache entry per
realm.

Cache misses should be very infrequent per realm.

If a realm has lots of deactivated realm emoji, then
there's a minor expense to deserialize them, but that
is gonna be dwarfed by all the other more expensive
operations in message-send.

I also renamed the two related functions.  I erred on
the side of using somewhat verbose names, as we don't
want folks to confuse the two use cases. Fortunately
there are somewhat natural affordances to use one or
the other, and mypy helps too.

Finally, I use realm_id instead of realm in places
where we don't need the full Realm object.

Lauryn Menard 3dfdbbc775 welcome-emails: Separate followup_day1 email from other welcome emails.
The initial followup_day1 email confirms that the new user account
has been successfully created and should be sent to the user
independently of an organization's setting for send_welcome_emails.

Here we separate out the followup_day1 email into a separate function
from enqueue_welcome_emails and create a helper function for setting
the shared welcome email sender information.

The followup_day1 email is still a scheduled email so that the initial
account creation and log-in process for the user remains unchanged.

Fixes #25268.

Alex Vandiver a076d49be7 sentry: Reduce http timeout.
This helps reduce the impact on busy uwsgi processes in case there are
slow timeout failures of Sentry servers.  The p99 is less than 300ms,
and p99.9 per day peaks at around 1s, so this will not affect more
than .1% of requests in normal operation.

This is not a complete solution (see #26229); it is merely stop-gap
mitigation.

Steve Howell 763b5e0741 default streams: Extract library functions.
I created zerver/lib/default_streams.py, so that various
views and events.py don't have to awkwardly reach into
an "actions" file.

I copied over two functions verbatim from actions/default_streams.py:

    get_default_streams_for_realm
    streams_to_dicts_sorted

The latter only remains as an internal detail in the new library.

I also created two new helpers:

    get_default_stream_ids_for_realm:

        This is both faster and easier to use in all the places
        where we only need to get a set of default stream ids.

    get_default_streams_for_realm_as_dicts:

        This just wraps the prior calls to
        streams_to_dicts_sorted(get_default_streams_for_realm(...)),
        and it doesn't yet address the slowness of the underlying
        code.

        All the "real" code should be functionally the same.

        In a few tests I now use this wrapper instead of
        calling get_default_streams_for_realm, just to get
        slightly deeper coverage.

Steve Howell 6d57340d48 narrow: Pass modern narrow to do_events_register.
We now upstream the conversion of legacy tuples
into the callers of do_events_register. For the
codepath that builds the home view, this allows
for cleaner code in the caller.  For the /register
endpoint, we have to do the conversion, but that
isn't super ugly, as that's an appropriate place
to deal with legacy formats and clean them up.

We do have to have do_events_register downgrade
the format back to tuples to pass them into
request_event_queue, because I don't want to
change any serialization formats. The conversion
is quite simple, and it has test coverage.

Mateusz Mandera 0bb0220ebb saml: Implement SP-initiated Logout.
Closes #20084

This is the flow that this implements:
1. A logged-in user clicks "Logout".
2. If they didn't auth via SAML, just do normal logout. Otherwise:
3. Form a LogoutRequest and redirect the user to
https://idp.example.com/slo-endpoint?SAMLRequest=<LogoutRequest here>
4. The IdP validates the LogoutRequest, terminates its own user session
and redirects the user to
https://thezuliporg.example.com/complete/saml/?SAMLRequest=<LogoutResponse>
with the appropriate LogoutResponse. In case of failure, the
LogoutResponse is expected to express that.
5. Zulip validates the LogoutResponse and if the response is a success
response, it executes the regular Zulip logout and the full flow is
finished.

Sahil Batra 4c4caa7be4 CVE-2023-32677: Check permission to subscribe other users in invites.
This commit updates the API to check the permission to subscribe other
users while inviting.  The API will error if the user passes the
"stream_ids" parameter (even when it contains only default streams)
and the calling user does not having permission to subscribe others to
streams.

For users who do not have permission to subscribe others, the
invitee will be subscribed to default streams at the time of
accepting the invite.

There is no change for multiuse invites, since only admins are allowed
to send them, and admins always have the permission to subscribe
others to streams.

Mateusz Mandera a23b077b79 CVE-2023-28623: Prevent unauthorized signup with ldap + external auth.
Since 74dd21c8fa in Zulip Server 2.1.0, if:

  of ZulipLDAPAuthBackend and EmailAuthBackend) are the only ones
  enabled in AUTHENTICATION_BACKENDS in /etc/zulip/settings.py
- The organization permissions don't require invitations to join

...then an attacker can create a new account in the organization with
an arbitrary email address in their control that's not in the
organization's LDAP directory.

The impact is limited to installations which have the specific
combination of authentication backends described above, in addition to
having the "Invitations are required for joining this organization
organization" permission disabled.

Mateusz Mandera 3ed2a30e01 maybe_send_to_registration: Remove password_required arg.
This argument was added with the default incorrectly set to `True` in
bb0eb76bf3 - despite
`maybe_send_to_registration` only ever being called in production code
in a single place, with `password_required=False` explicitly. And then
it just got carried forward through refactors.

`maybe_send_to_registration` was/is also called twice in tests, falling
back to the default, but the `password_required` value is irrelevant to
the tests - and if anything letting it use the `True` has been wrong,
due to not matching how this function is actually used.

Alex Vandiver b312a86ada sentry: Add the observed user's IP address before forwarding.
The default for Javascript reporting is that Sentry sets the IP
address of the user to the IP address that the report was observed to
come from[^1].  Since all reports come through the Zulip server, this
results in all reports being "from" one IP address, thus undercounting
the number of affected unauthenticated users, and making it difficult
to correlate Sentry reports with server logs.

Consume the Sentry Envelope format[^2] to inject the submitting
client's observed IP address, when possible.  This ensures that Sentry
reports contain the same IP address that Zulip's server logs do.
