Alex Vandiver e0d3176098 digest: Increase size of stream cache.
Since the cache is flushed when the cutoff or realm changes, the
maximum size of the cache should cap out at the number of streams in
the realm.  Raise the max cache size, now that this will not simply
lead to useless cache space for smaller servers.

There is now no longer any reason to have the scheduled_email

Alex Vandiver b555d3f553 digest: Cache per-stream recent topics, rather than batching.
The query plan for fetching recent messages from the arbitrary set of
streams formed by the intersection of 30 random users can be quite
bad, and can descend into a sequential scan on `zerver_recipient`.
Worse, this work of pulling recent messages out is redone if the
stream appears in the next batch of 30 users.

Instead, pull the recent messages for a stream on a one-by-one basis,
but cache them in an in-memory cache.  Since digests are enqueued in
30-user batches but still one-realm-at-a-time, work will be saved both
in terms of faster query plans whose results can also be reused across
batches.

This requires that we pull the stream-id to stream-name mapping for
_all_ streams in the realm at once, but that is well-indexed and
unlikely to cause performance issues -- in fact, it may be faster
than pulling a random subset of the streams in the realm.

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.

Adrián Oliva 732ad89f3d markdown: Fix URL link topic skipping query.
When searching for links inside a topic name, the question mark (?)
was used to split the topic. If a URL had a query after the URL
(e.g., "?foo=bar"), then the query was trimmed from the URL.

Removing the question mark from `basic_link_splitter` is sufficient
to fix this issue. The `get_web_link_regex` function then removes
the trailing punctuation if any, including literal question marks.

Fixes #26368.

N-Shar-ma 8c91c91d86 widgets: Fix bug where a new line right after /todo broke rendering.
When there was no space right after `/todo` but there was content on a
new line, the message would be rendered plainly, not as a todo widget.
This was because we split on only the space character to then check if
the first token was a valid widget.

Now we split on both spaces and newlines to extract the widget name,
irrespective of whether it is followed by a space or a newline. This
results in the message being rendered as a todo widget as expected.

Zixuan James Li c336bf0398 api: Avoid programming errors due to nested Annotated types.
We want to reject ambiguous type annotations that set ApiParamConfig
inside a Union. If a parameter is Optional and has a default of None, we
prefer Annotated[Optional[T], ...] over Optional[Annotated[T, ...]].

This implements a check that detects Optional[Annotated[T, ...]] and
raise an assertion error if ApiParamConfig is in the annotation. It also
checks if the type annotation contains any ApiParamConfig objects that
are ignored, which can happen if the Annotated type is nested inside
another type like List, Union, etc.

Note that because
param: Annotated[Optional[T], ...] = None
and
param: Optional[Annotated[Optional[T], ...]] = None
are equivalent in runtime prior to Python 3.11, there is no way for us
to distinguish the two. So we cannot detect that in runtime.

Zixuan James Li f4caf9dd79 api: Add new typed_endpoint decorators.
The goal of typed_endpoint is to replicate most features supported by
has_request_variables, and to improve on top of it. There are some
unresolved issues that we don't plan to work on currently. For example,
typed_endpoint does not support ignored_parameters_supported for 400
responses, and it does not run validators on path-only arguments.

Unlike has_request_variables, typed_endpoint supports error handling by
processing validation errors from Pydantic.

Most features supported by has_request_variables are supported by
typed_endpoint in various ways.

To define a function, use a syntax like this with Annotated if there is
any metadata you want to associate with a parameter, do note that
parameters that are not keyword-only are ignored from the request:
```
@typed_endpoint
def view(
    request: HttpRequest,
    user_profile: UserProfile,
    *,
    foo: Annotated[int, ApiParamConfig(path_only=True)],
    bar: Json[int],
    other: Annotated[
        Json[int],
        ApiParamConfig(
            whence="lorem",
            documentation_status=NTENTIONALLY_UNDOCUMENTED
        )
    ] = 10,
) -> HttpResponse:
    ....
```

There are also some shorthands for the commonly used annotated types,
which are encouraged when applicable for better readability and less
typing:
```
WebhookPayload = Annotated[Json[T], ApiParamConfig(argument_type_is_body=True)]
PathOnly = Annotated[T, ApiParamConfig(path_only=True)]
```

Then the view function above can be rewritten as:
```
@typed_endpoint
def view(
    request: HttpRequest,
    user_profile: UserProfile,
    *,
    foo: PathOnly[int],
    bar: Json[int],
    other: Annotated[
        Json[int],
        ApiParamConfig(
            whence="lorem",
            documentation_status=INTENTIONALLY_UNDOCUMENTED
        )
    ] = 10,
) -> HttpResponse:
    ....
```

There are some intentional restrictions:
- A single parameter cannot have more than one ApiParamConfig
- Path-only parameters cannot have default values
- argument_type_is_body is incompatible with whence
- Arguments of name "request", "user_profile", "args", and "kwargs" and
  etc. are ignored by typed_endpoint.
- positional-only arguments are not supported by typed_endpoint. Only
  keyword-only parameters are expected to be parsed from the request.
- Pydantic's strict mode is always enabled, because we don't want to
  coerce input parsed from JSON into other types unnecessarily.
- Using strict mode all the time also means that we should always use
  Json[int] instead of int, because it is only possible for the request
  to have data of type str, and a type annotation of int will always
  reject such data.

typed_endpoint's handling of ignored_parameters_unsupported is mostly
identical to that of has_request_variables.

Anders Kaseorg 0ce6dcb905 mypy: Upgrade mypy from 1.4.1 to 1.5.1.
_default_manager is the same as objects on most of our models. But
when a model class is stored in a variable, the type system doesn’t
know which model the variable is referring to, so it can’t know that
objects even exists (Django doesn’t add it if the user added a custom
manager of a different name). django-stubs used to incorrectly assume
it exists unconditionally, but it no longer does.

Sahil Batra 5e1eb3cd44 events: Fix applying stream creation events in apply_event.
There was a bug in apply_event code where only a stream which

"never_subscribed" data irrespective of permission policy of
the stream as we already send stream creation events only to
those users who can access the stream. Due to the current
bug, private streams were not being added to "never_subscribed"
data in apply_event for admins as well. This commit fixes it
and also makes sure the "never_subscribed" list is sorted
which was not done before and was also a bug.

Mateusz Mandera c908b518ef CVE-2023-32678: Prevent unauthorized editing/deletion in priv streams.
Users who used to be subscribed to a private stream and have been
removed from it since retain the ability to edit messages/topics, and
delete messages that they used to have access to, if other relevant
organization permissions allow these actions. For example, a user may be
able to edit or delete their old messages they posted in such a private
stream. An administrator will be able to delete old messages (that they
had access to) from the private stream.

We fix this by fixing the logic in has_message_access (which lies at the
core of our message access checks - access_message() and
bulk_access_messages())
to not rely on only a UserMessage row for checking access but also
verify stream type and subscription status.

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 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.

Prakhar Pratyush 379a08eb1e message_send: Fix wildcard_mentioned flag unset for few participants.
For topic wildcard mentions, the 'wildcard_mentioned' flag is set
for those user messages having 'user_profile_id' in
'topic_participant_user_ids', i.e. all topic participants.

Earlier, the flag was set if the 'user_profile_id' exists in
'all_topic_wildcard_mention_user_ids'.
'all_topic_wildcard_mention_user_ids' contains the ids of those
users who are topic participants and have enabled notifications
for '@topic' mentions.

The earlier approach was incorrect, as it would set the
'wildcard_mentioned' flag only for those topic participants
who have enabled the notifications for '@topic' mention instead
of setting the flag for all the topic participants.

The bug was introduced in 4c9d26c.

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`.

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.

Steve Howell 1b7880fc21 push notifications: Go to the DB for streams.
We want to phase out the use of get_display_recipient

eliminate it. The next commit will eliminate the
dead code and make mypy types tighter.

This change will make push notifications slightly
slower in some situations, but we avoid all the
complexity of a cache, and this code tends to run
offline.

We could always make this code a bit more efficient
by being a little smarter about what data we fetch
up front. For example, get_apns_alert_title gets
called by a function that already has the stream
name. It's just a bit of a pain to refactor when
you have all the DM codepath mucked up with the
stream codepath.

Lauryn Menard 195e5b8dc1 events: Add test to remove existing value for custom profile field.
Adds a test for when a value for a user's custom profile field is
removed and not set to a new value. The omission of this event in
the tests was noted as a possibility in #22103, which updated the
API documentation for these events having `null` for the field
value.

When adding the test discovered that the events logic was not
deleting the field from the user object and instead setting it to
`None`, so fixes that logic as well. There was a similar bug fixed
in commit 96c61a1a41 for when custom profile fields are removed
from a realm.

Lauryn Menard c1cd5c527c events: Update raw user data fields once.
When applying realm_user update events, some of the event fields
for the person object were being updated to the same value in a
loop. Unnests those calls from the loop over the existing fields
so that they are only updated once.

The original nesting was introduced in commit 649fccde6b and
was expanded in other additions to the logic for these events.

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
existing stream which the user did not have access to before.

Steve Howell b825f52806 user groups: Find users more simply.
I move the helper user_ids_to_users to the only
place that it's used, and then I simplify it to
do a direct database query.

These endpoints aren't hit often enough to justify
caching complexity, and for really large user groups,
hitting the cache can actually be counterproductive.

Particularly when you add new users to an existing
group, the bulk of the cost is sending out
notification messages to users.

The only change to the test is that I added an
assertion on the query count.

Steve Howell 61a9f701bd cache: Use a single cache entry for cross-realm bots.
The cross-realm bots rarely change, and there are only
a few of them, so we just query them all at once and
put them in the cache.

Also, we put the dictionaries in the cache, instead of
the user objects, since there is nothing time-sensitive
about the dictionaries, and they are small. This saves
us a little time computing the avatar url and things
like that, not to mention marshalling costs.

This commit also fixes a theoretical bug where we would
have stale cache entries if somebody somehow modified
the cross-realm bots without bumping KEY_PREFIX.

Internally we no longer pre-fetch the realm objects for
the bots, but we don't get overly precise about picking
individual fields from UserProfile, since we rarely hit
the database and since we don't store raw ORM objects
in the cache.

The test diffs make it look like we are hitting the
cache an extra time, but the tests weren't counting
bulk fetches.  Now we only use a single key for all
bots rather a key per bot.

Steve Howell 0c92879f2a cross realm bots: Eliminate bulk_get_users confusion.
The bulk_get_users() function was only being used to
get cross-realm bots.

It appears that it was introduced in
f02e5b90f6 for that
specific use case.

Now we make the function more specific and test it more
accurately.

We also eliminate a lot of janky code and comments,
including some code that never had test coverage.

Incidentally, it appears that we did not have any code
to invalidate the cache keys here, and that is still
the case. In practice I assume people rarely
re-configure their cross-realm bots unless they are
upgrading the server, and then KEY_PREFIX comes into
play. 25fd4c5508 seems
to have caused that hopefully harmless regression.

A further step will be to make this cache more coarse,
since there are only a few cross-realm bots. The next
commit will hopefully simplify the code and address the
validation pitfall.
