sanchi-t af7ebde9e4 subscription: Include archived channels in streams list.
`is_archived` field is added to the stream and types.

Include a new `archived_channeels` client capability, to allow clients
to access data on archived channels, without breaking
backwards-compatibility for existing clients that don't know how to
handle these.

Also, included `exclude_archived` parameter to `/get-streams`,
which defaults to `true` as basic clients may not be interested
in archived streams.

Prakhar Pratyush e763d065a3 django_api: Rename 'send_event' to 'send_event_rollback_unsafe'.
This commit renames the 'send_event' function to
'send_event_rollback_unsafe' to reflect the fact that it doesn't
wait for the db transaction (within which it gets called, if any)
to commit and sends event irrespective of commit or rollback.

In most of the cases we don't want to send event in the case of
rollbacks, so the caller should be aware that calling the function
directly is rollback unsafe.

Anders Kaseorg 6988622fe8 ruff: Enable B023 Function definition does not bind loop variable.
Python’s loop scoping is misdesigned, resulting in a very common
gotcha for functions that close over loop variables [1].  The general
problem is so bad that even the Go developers plan to break
compatibility in order to fix the same design mistake in their
language [2].

Enable the Ruff rule function-uses-loop-variable (B023) [3], which
conservatively prohibits functions from binding loop variables at all.

Anders Kaseorg 7657cb4a0f django_api: Extract send_event_on_commit helper.
django-stubs 4.2.1 gives transaction.on_commit a more accurate type
annotation, but this exposed that mypy can’t handle the lambda default
parameters that we use to recapture loop variables such as

    for stream_id in public_stream_ids:
        peer_user_ids = …
        event = …

        transaction.on_commit(
            lambda event=event, peer_user_ids=peer_user_ids: send_event(
                realm, event, peer_user_ids
            )
        )

https://github.com/python/mypy/issues/15459

A workaround that mypy accepts is

        transaction.on_commit(
            (
                lambda event, peer_user_ids: lambda: send_event(
                    realm, event, peer_user_ids
                )
            )(event, peer_user_ids)
        )

But that’s kind of ugly and potentially error-prone, so let’s make a
helper function for this very common pattern.

        send_event_on_commit(realm, event, peer_user_ids)

Zixuan James Li 268f858f39 linkifier: Support URL templates for linkifiers.
This swaps out url_format_string from all of our APIs and replaces it
with url_template. Note that the documentation changes in the following
commits  will be squashed with this commit.

We change the "url_format" key to "url_template" for the
realm_linkifiers events in event_schema, along with updating
LinkifierDict. "url_template" is the name chosen to normalize
mixed usages of "url_format_string" and "url_format" throughout
the backend.

The markdown processor is updated to stop handling the format string
interpolation and delegate the task template expansion to the uri_template
library instead.

This change affects many test cases. We mostly just replace "%(name)s"
with "{name}", "url_format_string" with "url_template" to make sure that
they still pass. There are some test cases dedicated for testing "%"
escaping, which aren't relevant anymore and are subject to removal.
But for now we keep most of them as-is, and make sure that "%" is always
escaped since we do not use it for variable substitution any more.

Since url_format_string is not populated anymore, a migration is created
to remove this field entirely, and make url_template non-nullable since
we will always populate it. Note that it is possible to have
url_template being null after migration 0422 and before 0424, but
in practice, url_template will not be None after backfilling and the
backend now is always setting url_template.

With the removal of url_format_string, RealmFilter model will now be cleaned
with URL template checks, and the old checks for escapes are removed.

We also modified RealmFilter.clean to skip the validation when the
url_template is invalid. This avoids raising mulitple ValidationError's
when calling full_clean on a linkifier. But we might eventually want to
have a more centric approach to data validation instead of having
the same validation in both the clean method and the validator.

Fixes #23124.

Abhijeet Prasad Bodas ed58393079 message send: Optimize how user data is sent to Tornado.
Before this commit, we used to pre-calculate flags for user data and send
it to Tornado, like so:
```
{
    "id": 10,
    "flags": ["mentioned"],
    "mentioned": true,
    "online_push_enabled": false,
    "stream_push_notify": false,
    "stream_email_notify": false,
    "wildcard_mention_notify": false,
    "sender_is_muted": false,
}
```

This has the benefit of simplifying the logic in the event_queue code a bit.

However, because we sent such an object for each user receiving the event,
the string keys (like "stream_email_notify") get duplicated in the JSON
blob that is sent to Tornado.

For 1000 users, this data may take up upto ~190KB of space, which can
cause performance degradation in large organisations.

Hence, as an alternative, we send just the list of user_ids fitting
each notification criteria, and then calculate the flags in Tornado.
This brings down the space to ~60KB for 1000 users.

This commit reverts parts of following commits:
- 2179275
- 40cd6b5

We will in the future, add helpers to create `UserMessageNotificationsData`
objects from these lists, so as to avoid code duplication.

The `no_proxy` parameter does not work to remove proxying[1]; in this

Alex Vandiver e5f62d083e tornado: Merge the TORNADO_SERVER and TORNADO_PORTS configs.
Having both of these is confusing; TORNADO_SERVER is used only when
there is one TORNADO_PORT.  Its primary use is actually to be _unset_,
and signal that in-process handling is to be done.

Rename to USING_TORNADO, to parallel the existing USING_RABBITMQ, and
switch the places that used it for its contents to using
TORNADO_PORTS.

Alex Vandiver 5a9b6feb18 tornado: Retry POST requests from Django to Tornado.
While urllib3 retries all connection errors, it only retries a subset
of read errors, since not all requests are safe to retry if they are
not idempotent, and the far side may have already processed them once.
By default, the only methods that are urllib3 retries read errors on
are GET, TRACE, DELETE, OPTIONS, HEAD, and PUT.  However, all of the
requests into Tornado from Django are POST requests, which limits the
effectiveness of bb754e0902.

POST requests to `/api/v1/events/internal` are safe to retry; at worst,
they will result in another event queue, which is low cost and will be
GC'd in short order.

POST requests to `/notify_tornado` are _not_ safe to retry, but this
codepath is only used if USING_RABBITMQ is False, which only occurs
during testing.

Enable retries for read errors during all POSTs to Tornado, to better
handle Tornado restarts without 500's.

Alex Vandiver ff94254598 tornado: Log to files by port number.
Without an explicit port number, the `stdout_logfile` values for each
port are identical.  Supervisor apparently decides that it will
de-conflict this by appending an arbitrary number to the end:

```
/var/log/zulip/tornado.log
/var/log/zulip/tornado.log.1
/var/log/zulip/tornado.log.10
/var/log/zulip/tornado.log.2
/var/log/zulip/tornado.log.3
/var/log/zulip/tornado.log.7
/var/log/zulip/tornado.log.8
/var/log/zulip/tornado.log.9
```

This is quite confusing, since most other files in `/var/log/zulip/`
use `.1` to mean logrotate was used.  Also note that these are not all
sequential -- 4, 5, and 6 are mysteriously missing, though they were
used in previous restarts.  This can make it extremely hard to debug
logs from a particular Tornado shard.

Give the logfiles a consistent name, and set them up to logrotate.
