Eeshan Garg d2901892e2 streams: Add notifications for message retention policy updates.
This is a part of #20289.

Eeshan Garg 2cdaae681d actions: Rename do_change_plan_type -> do change_realm_plan_type.
We will soon be adding an equivalent function for RemoteZulipServer,
so it makes sense to rename this function to be more descriptive.

Lauryn Menard 7713b371a5 api: Migrate `/update-subscription-settings` response value.
Migrates the `/update-subscription-settings` api endpoint to the
`ignored_parameters_unsupported` model, which is also currently used
by `/update-settings` and `update-realm-user-settings-defaults`.

This change is a step towards preparing for an eventual migration to
have all endpoints return an `ignored_parameters_unsupported` block.

Previously the `/update-subscription-settings` endpoint returned a
copy of the data object sent in the request.

Fixes #15307.

Sahil Batra ad99b4fac9 streams: Allow changing stream to be web-public based on creation setting.
We allow a user to make an existing stream web-public only if user is
allowed to create web-public streams.

Eeshan Garg b325a4f1be realm: Rename plan type constants to be more descriptive.
It is confusing to have the plan type constants not be namespaced
by the thing they represent. We already have a namespacing
convention in place for constants, so we should use it for
Realm.plan_type as well.

Sahil Batra e575f83351 test_subs: Remove _test_user_settings_for_adding_streams.
This commit removes _test_user_settings_for_adding_streams
and its callers for testing public and private streams
because it uses excessive mocking and we also test the same
thing in _test_user_settings_for_creating_streams without
mocking, so this test doesn't add anything.

Sahil Batra 2c2c19c4d4 streams: Restrict creating web public streams based on new setting.
This commit restricts creating web public streams based on the

Sahil Batra 3916181770 models: Add can_create_web_public_streams helper.
This commit adds can_create_web_public_streams helper

user is allowed to create a web-public stream or not.

This commit also adds the checks for Realm.POLICY_OWNERS_ONLY
in check_has_permission_policies.

Sahil Batra be0387b189 test_subs: Enforce invite_only argument to be named.
This commit enforces invite_only argument to be named

add is_web_public argument in further commits.

Ganesh Pawar fa928d5cd1 streams: Split setting for stream creation policy.
Users wanted a feature where they could specify
which users can create public streams and which users can
create private streams.

This splits stream creation code into two parts,
public and private stream creation.

Fixes #17009.

Aman Agrawal 5138652810 update_stream_backend: Add ability to make streams web public.
We allow clients to make existing streams web public via the API.

This feature is still disabled via settings in production
environments, because we may have additional policy rules or UI
warnings we wish to add to this sort of conversion.

Aman Agrawal 6a78112940 subscribe: Allow web public stream creation via the API.
User can now create web public stream via the /subscribe API.
So, when a web public stream present in the API request does not
exist, it will be created now by specifying the is_web_public
parameter. The parameter would have been ignored without this
commit.

Tim Abbott 95606a7347 api: Return user IDs, not display emails, in subscribers endpoints.
Sometime in the deep past, Zulip the GET /users/me/subscriptions
endpoint started returning subscribers.  We noticed this and made it
optional via the include_subscribers parameter in
1af72a2745, however, we didn't notice
that they were being returned as emails rather than user IDs.

We migrated the core /register code paths to use subscriber IDs years
ago; this change completes that for the endpoints we forgot about.

The documentation allowed this error because we apparently had no
tests for this code path that used the actual API.

Vishnu KS 4ad592ed4f populate_db: Use do_create_realm for creating zulip realm.
Since do_create_realm also creates general and core team streams,
we rename general to verona right after the realm is created. Mostly
because we dont really want two additional streams and this might
probably make it easy to review things.

There are puppeteer test changes because, we have a new "core team"
stream in tests as well as there is a new default notification stream
"Verona". Because of this tests in message-basics for example have
to be changed since the newly added core team affects the order in
which we navigate through the streams using arrow keys.

The extra await for selector was added in subscriptions test to make
the tests wait. Without the await the tests were passing ocassionally
and failing in some other times.

Fixes #6967

Mateusz Mandera 50bfbb588e subs: Allow filtering by is_user_active in get_active_subscriptions.
get_active_subscriptions_for_stream_id should allow specifying whether
subscriptions of deactivated users should be included in the result.
Active subs of deactivated users are  a subtlety that's easy to miss
when writing relevant code, so we make include_deactivated_users a
mandatory kwarg - this will force callers to definitely give thought to
whether such subs should be included or not.

This commit is just a refactoring, we keep original behavior everywhere
- there are places where subs of deactivates users should probably be
excluded but aren't - we don't fix that here, it'll be addressed in
follow-up commits.

Mateusz Mandera 6e11754642 CVE-2021-30478: Prevent API super users from forging messages to other organizations.
A bug in the implementation of the can_forge_sender permission
(previously is_api_super_user) resulted in users with this permission
being able to send messages appearing as if sent by a system bots,
including to other organizations hosted by the same Zulip installation.

- The send message API had a bug allowing an api super user to
  use forging to send messages to other realms' streams, as a
  cross-realm bot. We fix this most directly by eliminating the
  realm_str parameter - it is not necessary for any valid current use
  case. The email gateway doesn't use this API despite the comment in
  that block suggesting otherwise.
- The conditionals inside access_stream_for_send_message are changed up
  to improve security. They were generally not ordered very well,
  allowing the function to successfully return due to very weak
  acceptance conditions - skipping the higher importance checks that
  should lead to raising an error.
- The query count in test_subs is decreased because
  access_stream_for_send_message returns earlier when doing its check
  for a cross-realm bot sender - some subscription checking queries are
  skipped.
- A linkifier test in test_message_dict needs to be changed. It didn't
  make much sense in the first place, because it was creating a message
  by a normal user, to a stream outside of the user's realm. That
  shouldn't even be allowed.

sahil839 685fbffd91 tests: Refactor check_has_permission_policies to check for all user roles.
We refactor check_has_permission_policies to check for all user roles for
each value of policy. This will help in handle a case where a guest is
allowed to do something but moderator isn't.

We need to do user_profile.refresh_from_db() in validation_func because
the realm object from user_profile is used in has_permission and we need
updated realm instance after changing the policy.

This is a follow-up commit to 9a4c58cb.

Abhijeet Prasad Bodas 2f56f8d0ed mute user: Mark as read new messages.
Messages sent by muted users are marked as read
as soon as they are sent (or, more accurately,
while creating the database entries itself), regardless
of type (stream/huddle/PM).

ede73ee4cd, makes it easy to
pass a list to `do_send_messages` containing user-ids for
whom the message should be marked as read.
We add the contents of this list to the set of muter IDs,
and then pass it on to `create_user_messages`.

This benefits from the caching behaviour of `get_muting_users`
and should not cause performance issues long term.

The consequence is that messages sent by muted users will
not contribute to unread counts and notifications.

This commit does not affect the unread messages
(if any) present just before muting, but only handles
subsequent messages. Old unreads will be handled in
further commits.

WookieMonkeys 1b6f68bb59 stream: Add entropy to deactivated streams.
Adding an additional `!` to the stream name each time a stream is
deactivated, to a maximum of 21 times, effectively limits number of
times a stream with a given name can be deactivated.  This is unlikely
to come up in common usage, but may be confusing when testing.

Change what we prepend to deactivated stream names to something with
more entropy than just `!`, by instead prepending a substring of hash
of the stream's ID.  `!`s.  Using 128 bits of the hash means that it
will require more than 10^18th renames to have a 1% chance of collision.

Because too-long stream names are also truncated at 60 characters,
having this entropy in the beginning of the name also helps address
potential issues from stream names that differed only in, e.g. the
60th character.

false. This approach is explained in detail below.

Following hierarchy of roles is considered for these tests -
1. Realm admin
2. Full members
3. Members
4. Guests.

Then if the policy is set to admins only, we check that the having
role as admin returns true and the role just below that, i.e. full
member returns false. Similarly, if the policy is set to members
only, we check that a member should return true and role below it
which is guest should return false. We basically follow these as
we can assume that if a user with particular role cannot do the
required task, then user with role below in the hierarchy would
be not allowed to do the task too.

This commit refactors the above mentioned two tests to have above
explained workflow.

sahil839 bc72d2dbc4 tests: Remove unnecessary use of do_change_user_role in test_subs.
This commit removes the unnecessary do_change_user_role function
in test_can_subcribe_other_users. This was added in 1aebf3cab
which replaced the multiple functions like do_change_is_admin
and do_change_is_guest with do_change_user_role.

Previously two functions do_change_is_admin and do_change_is_guest
were used because there were two flags is_realm_admin and is_guest
which were used to determine the role of a user. But then we added
a single field role to UserProfile and removed the multiple flags
and thus also replaced the different functions with a single
do_change_user_role. With addition of a new field role, two
different do_change_* functions were not needed as we only have
a role field instead of different flags, but this was missed in
1aebf3cab and this commit fixes it.

Steve Howell d9740045a5 refactor: Eliminate checks in build_stream_dict_for_sub.
We eliminate some redundant checks.

We also consistently provide a `subscribers` field
in our stream data with `[]`, even if our users
can't access subscribers.  We therefore bump
the API version and tweak the docs.  (See further
down for a detailed justification of the change.)

Even though it is sometimes fine to have redundant code
that is defensive in nature, some upcoming changes are gonna
move subscriber-related logic out of build_stream_dict_for_sub
for certain codepaths as part of our effort to streamline
the payload for subscribers within page_params.

So we can't rely on the code that I removed here
inside of build_stream_dict_for_sub.

Anyway, it makes more sense to do these checks explicitly
in the validate function.

The code in build_stream_dict_for_sub was almost effectively
a noop, since the validation function was already preventing
us from getting subscriber info.  The only difference it
made was sometimes converting `[]` to `None`, and then
subsequently omitting the subscribers field.

Neither ZT nor the webapp make any distinction between
`[]` or <missing key> for the `subscribers` data in
`page_params`.

The webapp has had this code for a long time (and now
equivalent code elsewhere in this PR):

    if (!Object.prototype.hasOwnProperty.call(sub, "subscribers")) {
        sub.subscribers = new LazySet([]);
    }

The webapp calculates access based on booleans, anyway:

    sub.can_access_subscribers =
        page_params.is_admin || sub.subscribed ||
        (!page_params.is_guest && !sub.invite_only);

And ZT would choke if `subscribers` were missing, except that
it never gets to the relevant code due to other checks:

    def get_other_subscribers_in_stream(<snip>):
        assert stream_id is not None or stream_name is not None

        if stream_id:
            assert self.is_user_subscribed_to_stream(stream_id)

            return [sub
                    for sub in self.stream_dict[stream_id]['subscribers']
                    if sub != self.user_id]
        else:
            return [sub
                    for _, stream in self.stream_dict.items()
                    for sub in stream['subscribers']
                    if stream['name'] == stream_name
                    if sub != self.user_id]

You could make a semantic argument that we should prefer
<missing key> to `[]` when subscribers aren't even available, but
we have precedent from the way that `bulk_get_subscriber_user_ids`
has traditionally populated its result:

    result: Dict[int, List[int]] =
        {stream["id"]: [] for stream in stream_dicts}

If we changed `stream_dicts` to `target_stream_dicts` we
would faciliate a move toward `None`, but it would just cause
headaches for other server code as well as the frontends
(which, to reiterate, already prefer the empty array
for convenience).

Mateusz Mandera d0dc04a093 models: Rename is_api_super_user to can_forge_sender, 2020-12-21 13:15:39 -08:00
Steve Howell c1f134a3a4 performance: Use ORM to fetch sender in render_markdown.
In 709493cd75 (Feb 2017)
I added code to render_markdown that re-fetched the
sender of the message, to detect whether the message is
a bot.

It's better to just let the ORM fetch this.  The
message object should already have sender.

The diff makes it look like we are saving round trips
to the database, which is true in some cases.  For
the main message-send codepath, though, we are only
saving a trip to memcached, since the middleware
will have put our sender's user object into the
cache.  The test_message_send test calls internally
to check_send_stream_message, so it was actually
hitting the database in render_markdown (prior to
my change).

Steve Howell 637f596751 tests: Fix queries_captured to clear cache up front.
Before this change we were clearing the cache on
every SQL usage.

The code to do this was added in February 2017
in 6db4879f9c.

Now we clear the cache just one time, but before
the action/request under test.

Tests that want to count queries with a warm
cache now specify keep_cache_warm=True.  Those
tests were particularly flawed before this change.

In general, the old code both over-counted and
under-counted queries.

It under-counted SQL usage for requests that were
able to pull some data out of a warm cache before
they did any SQL.  Typically this would have bypassed
the initial query to get UserProfile, so you
will see several off-by-one fixes.

The old code over-counted SQL usage to the extent
that it's a rather extreme assumption that during
an action itself, the entries that you put into
the cache will get thrown away.  And that's essentially
what the prior code simulated.

Now, it's still bad if an action keeps hitting the
cache for no reason, but it's not as bad as hitting
the database.  There doesn't appear to be any evidence
of us doing something silly like fetching the same
data from the cache in a loop, but there are
opportunities to prevent second or third round
trips to the cache for the same object, if we
can re-structure the code so that the same caller
doesn't have two callees get the same data.

Note that for invites, we have some cache hits
that are due to the nature of how we serialize
data to our queue processor--we generally just
serialize ids, and then re-fetch objects when
we pop them off the queue.

Steve Howell 7ff3859136 subscriber events: Change schema for peer_add/peer_remove.
We now can send an implied matrix of user/stream tuples
for peer_add and peer_remove events.

The client code basically does this:

    for stream_id in event['stream_ids']:
        for user_id in event['user_ids']:
            update_sub(stream_id, user_id)

We used to send individual events, which gets real
expensive when you are creating new streams. For
the case of copy-to-stream case, we should see
events go from U to 1, where U is the number of users
added.

Note that we don't yet fully optimize the potential
of this schema.  For adding a new user with lots
of default streams, we still send S peer_add events.

And if you subscribe a bunch of users to a bunch of
private streams, we only go from U * S to S; we can't
optimize it down to one event easily.

Steve Howell 85ed6f332a performance: Avoid Recipient lookup for stream messages.
All the fields of a stream's recipient object can
be inferred from the Stream, so we just make a local
object.  Django will create a Message object without
checking that the child Recipient object has been
saved.  If that behavior changes in some upgrade,
we should see some pretty obvious symptom, including
query counts changing.

Tweaked by tabbott to add a longer explanatory comment, and delete a
useless old comment.
