Mateusz Mandera ccfcc186ad subs: Fix subscriber_..._history_access to not exclude subbed guests.
Guests are supposed to have stream history access to public streams
they're subscribed to.

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.

sahil839 39c9845cb0 streams: Raise same error for all values of invite_to_stream_policy.
We keep the error message same for all cases when a user is not
allowed to subscribe others for all values of invite_to_stream_policy.

We raise error with different message for guest cases because it
is handled by decorators. We aim to change this behavior in future.

Explaining the details in error message isn't much important as
we do not show errors probably in API only, as we do not the show
the options itself in the frontend.

sahil839 9ad6a856a9 tests: Extract a single function to test functions using has_permission.
The tests for can_create_streams and can_subscribe_other_users shares a
lot of code and we deduplicate the code by extracting most of the code
as check_has_permission_policies which will now be called by the two
tests test_can_create_streams and test_can_subscribe_other_users.

This will also help in avoiding the duplication of code when we will
convert more policies to use COMMON_POLICY_TYPES.

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.

Fixes #17016.

with do_change_user_role and do_set_realm_property functions

sahil839 683b6f7d65 tests: Refactor test_can_create_streams and test_can_subscribe_other_users.
We refactor test_can_create_streams and test_can_subscribe_other_users
in test_subs.py. We want to follow a specific order in such tests
which is just set the policy value one by one and then checking
that the role in policy returns true and role just below that returns
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).

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

we should see some pretty obvious symptom, including
query counts changing.

We now pass stream_recipient_id when we queue
up work for do_mark_stream_messages_as_read.

This generally saves about 3 queries per
user when we unsubscribe them from a stream.

      and recipient data being returned in the

2020-10-16 12:58:11 -07:00
Steve Howell b4346d0276 performance: Extract subscribers/peers in bulk.
We replace get_peer_user_ids_for_stream_change
with two bulk functions to get peers and/or
subscribers.

Note that we have three codepaths that care about
peers:

    subscribing existing users:
        we need to tell peers about new subscribers
        we need to tell subscribed user about old subscribers

    unsubscribing existing users:
        we only need to tell peers who unsubscribed

    subscribing new user:
        we only need to tell peers about the new user
        (right now we generate send_event
        calls to tell the new user about existing
        subscribers, but this is a waste
        of effort that we will fix soon)

The two bulk functions are this:

    bulk_get_subscriber_peer_info
    bulk_get_peers

They have some overlap in the implementation,
but there are some nuanced differences that are
described in the comments.

Looking up peers/subscribers in bulk leads to some
nice optimizations.

We will save some memchached traffic if you are
subscribing to multiple public streams.

We will save a query in the remove-subscriber
case if you are only dealing with private streams.

Steve Howell a9356508ca events: Stop sending occupy/vacate events.
We used to send occupy/vacate events when
either the first person entered a stream
or the last person exited.

It appears that our two main apps have never
looked at these events.  Instead, it's
generally the case that clients handle
events related to stream creation/deactivation
and subscribe/unsubscribe.

Note that we removed the apply_events code
related to these events.  This doesn't affect
the webapp, because the webapp doesn't care
about the "streams" field in do_events_register.

There is a theoretical situation where a
third party client could be the victim of
a race where the "streams" data includes
a stream where the last subscriber has left.
I suspect in most of those situations it
will be harmless, or possibly even helpful
to the extent that they'll learn about
streams that are in a "quasi" state where
they're activated but not occupied.

We could try to patch apply_event to
detect when subscriptions get added
or removed. Or we could just make the
"streams" piece of do_events_register
not care about occupy/vacate semantics.
I favor the latter, since it might
actually be what users what, and it will
also simplify the code and improve
performance.

Steve Howell e7a8c7ac48 test: Improve tests for bulk-adding subscribers.
This is a more thorough test of adding multiple
streams for multiple users, including streams
that users have already subscribed to.

The extra queries here are due to the fact
that we call `principal_to_user_profile` in
a loop in the view.  So that's an example
of O(N) overhead.  We may be able to bulk-fetch
these users eventually.

Steve Howell c29ba75135 refactor: Extract send_messages_for_new_subscribers.
This is a pure extraction, except that I remove a
redundant check that `len(principals) > 0`.  Whenever
that value is false, then `new_subscriptions` will
only have one possible entry, which is the current
user, and we skip that in the loop.

Steve Howell 3b338ec32e performance: Optimize filter_stream_authorization.

streams.  Still, we want to avoid this.

This commit also makes `test_bulk_subscribe_many`
do more work, and the change to the test helped
me discover this bug.

Steve Howell 598601e8fc stream events: Prevent spurious events.

Steve Howell 9df9934ed6 refactor: Pass realm to bulk_add_subscriptions.

This may be overkill--I would also be happy if we
just included the assertions from this commit.

Steve Howell fbe45fa889 test helpers: Tweak common_subscribe_to_streams.
We assert that the post was successful, to give
more immediate feedback for tests that don't
bother to check the return value and may be
implicitly assuming this method just works in
all cases.

And we also make it more convenient for tests
that are happy-path tests--they don't have to
do the assertion themselves.  (And they're still
free to do deeper checks on the json.)

We opt out with allow_fail=True.  We probably want
a more direct API eventually for tests that are
clearly trying to test the failure path for
subscribing to streams.

It's possible that a couple tests here that I added
allow_fail=True to just have flawed data setup--
I don't have time to investigate all cases, but
hopefully they will at least stand out more.

Steve Howell 00e60c0c91 events: Use stream_id for peer_add/peer_remove.
Two things were broken here:
    * we were using name(s) instead of id(s)
    * we were always sending lists that only
      had one element

Now we just send "stream_id" instead of "subscriptions".

If anything, we should start sending a list of users
instead of a list of streams.  For example, see
the code below:

    if peer_user_ids:
        for new_user_id in new_user_ids:
            event = dict(type="subscription", op="peer_add",
                         stream_id=stream.id,
                         user_id=new_user_id)
            send_event(realm, event, peer_user_ids)

don't use this.

This is a full-stack change:

    - JS code

It's all pretty simple--just use stream_id instead
of stream_name.

I am 99% sure we don't document this API nor use it
in mobile, so it should be a safe change.

Steve Howell 1306239c16 tests: Use email/delivery_email more explicitly.
We try to use the correct variation of `email`
or `delivery_email`, even though in some
databases they are the same.

(To find the differences, I temporarily hacked
populate_db to use different values for email
and delivery_email, and reduced email visibility
in the zulip realm to admins only.)

In places where we want the "normal" realm
behavior of showing emails (and having `email`
be the same as `delivery_email`), we use
the new `reset_emails_in_zulip_realm` helper.

A couple random things:

    - I fixed any error messages that were leaking
      the wrong email

    - a test that claimed to rely on the order
      of emails no longer does (we sort user_ids
      instead)

    - we now use user_ids in some place where we used
      to use emails

    - for IRC mirrors I just punted and used
      `reset_emails_in_zulip_realm` in most places

    - for MIT-related tests, I didn't fix email
      vs. delivery_email unless it was obvious

I also explicitly reset the realm to a "normal"
realm for a couple tests that I frankly just didn't
have the energy to debug.  (Also, we do want some
coverage on the normal case, even though it is
"easier" for tests to pass if you mix up `email`
and `delivery_email`.)

In particular, I just reset data for the analytics
and corporate tests.

If you're gonna use the user in the
rest of the test:

    hamlet = self.example_user('hamlet')
    self.login_user(hamlet)

If you are specifically testing
email/password logins (used only in 4 places):

    self.login_by_email(email, password)

And for failures uses this (used twice):

    self.assert_login_failure(email)

Steve Howell c235333041 test performance: Pass in users to api_* helpers.
This reduces query counts in some cases, since
we no longer need to look up the user again. In
particular, it reduces some noise when we
count queries for O(N)-related tests.

The query count is usually reduced by 2 per
API call.  We no longer need to look up Realm
and UserProfile.  In most cases we are saving
these lookups for the whole tests, since we
usually already have the `user` objects for
other reasons.  In a few places we are simply
moving where that query happens within the
test.

In some places I shorten names like `test_user`
or `user_profile` to just be `user`.

Steve Howell 5e2a32c936 tests: Use users in send_*_message.
This commit mostly makes our tests less

It also sets us up to have more scrutiny
on delivery_email/email in the future
for things that actually matter.  (This is
a prep commit for something along those
lines, kind of hard to explain the full
plan.)

are sort of just filters on top of this), but
obviously we want explicit coverage here.  Also,

We need to adjust query counts in a few tests that now are a bit
cheaper because they now can take advantage of a Client object created

Ryan Rehman 174b2abcfd settings: Migrate to stream_post_policy structure.
This commit includes a new `stream_post_policy` setting,
by replacing the `is_announcement_only` field from the Stream model,
which is done by mirroring the structure of the existing
`create_stream_policy`.

It includes the necessary schema and database migrations to migrate
the is_announcement_only boolean field to stream_post_policy,
a smallPositiveInteger field similar to many other settings.

This change is done to allow organization administrators to restrict
new members from creating and posting to a stream. However, this does
not affect admins who are new members.

With many tweaks by tabbott to documentation under /help, etc.

a subscription.

New automated tests were added for the API, events system and front-end.
In manual testing, we checked that modifying the setting in the front end

were not behaving exactly as expected in manual testing; see

Mateusz Mandera c779bb1959 messages: Don't use display_recipient values from cached message_dicts.
The user information in display_recipient in cached message_dicts
becomes outdated if the information is changed in any way.

In particular, since we don't have a way to find all the message
objects that might contain PMs after an organization toggles the
setting to hide user email addresses from other users, we had a
situation where client might see inaccurate cached data from before
the transition for a period of up to hours.

We address this by using our generic_bulk_cached_fetch toolchain to
ensure we always are fetching display_recipient data from the database
(and/or a special recipient_id -> display_recipient cache, which we
can flush easily).

meiomorphism 1af72a2745 subscriptions: Avoid sending unneeded subscriber information.
The `users/me/subscriptions` endpoint accidentally started returning
subscriber information for each stream.  This is convenient, but
unnecessarily costly for those clients which either don't need it
(most API apps) or already acquire this information via /register
(including Zulip's apps).

This change removes that data set from the default response.  Clients
which had come to rely on it, or would like to rely on it in future,
may still access it via an additional documented API parameter.

When a person creates a new realm, they'll likely want to create a

to have to mark all of the new stream notification messages as read.

as read by the stream creator.

Harshit Bansal b553507412 subscriptions: Migrate notification setting defaults model.
This commit migrates the Subscription's notification fields from a
BooleanField to a NullBooleanField where a value of None means to
inherit the value from user's profile.

Also includes a migrations to set the corresponding settings to None
if they match the user profile's values. This migration helps us in
getting rid of the weird "Apply to all" widget that we offered on
subscription settings page.

The mobile apps can't handle None appearing as the stream-level
notification settings, so for backwards-compatibility we arrange to
only send True/False to the mobile apps by applying those defaults
server-side.  We introduce a notification_settings_null value within a
client_capabilities structure that newer versions of the mobile apps
can use to request the new model.

This mobile compatibility code is pretty effectively tested by the
existing test_events tests for the subscriptions subsystem.

Previously, the subscription color attribute had a validator of
check_string, but this is insufficient. Hence this commit update the
validator used to check_color. Fixes #11268.

sahil839 4dcccf32f8 zerver: Add feature for notification at rename of a stream.
Feature of sending notification to the stream using notification bot
is added. user_profile is also passed to do_rename_stream for using
the name of user who renamed the stream in notification.
Notification is sent to the stream using
internal_send_stream_message in do_rename_stream.

Fixes #11034.

Tim Abbott e603237010 email: Convert accounts code to use delivery_email.
A key part of this is the new helper, get_user_by_delivery_email.  Its
verbose name is important for clarity; it should help avoid blind
copy-pasting of get_user (which we'll also want to rename).
Unfortunately, it requires detailed understanding of the context to
figure out which one to use; each is used in about half of call sites.

Another important note is that this PR doesn't migrate get_user calls
in the tests except where not doing so would cause the tests to fail.
This probably deserves a follow-up refactor to avoid bugs here.

Steve Howell a6bc3886e6 refactor: Extract send_peer_remove_event().
This prevents leaking some variables into an already
cluttered function.

We also add test coverage for what's now an
early-exit condition in the new function--we exempt
public MIT streams from these events.

Steve Howell 092bb6a728 tests: Refactor test_bulk_subscribe_MIT().
We extract a couple local vars to avoid

We also explictly set the stream as a zephyr stream.

zhoufeng1989 d5f752df84 tests: Tests query count when creating stream with subscriptions API.
These test cases are used to test the cost of stream creation.
Three scenarios of stream creation are covered:
1) create a public stream;
2) create a private stream;
3) create a public stream with announce=true when there is a notification stream.

Fix: #4804.

We have defensive code in functions for combinations

in practice, buts this gets us some line coverage.

Yashashvi Dave 6e136be975 default stream: Allows admins to remove any default stream.
This fixes a bug where administrators couldn't remove private
unsubscribed streams from the "default streams" list, because
access_stream_by_name didn't give them access to the stream object.

Shubham Padia 1015b2fc44 subs: Refactor and add tests for UserProfile.can_create_streams.
This is a preparatory refactor for adding
UserProfile.can_subscribe_other_users.
Although there existed a test for limiting users from creating
streams at `test_subs.test_user_settings_for_adding_streams`,
it did not test the logic inside can_add_streams, tests have
been added to solve that issue.

Rishi Gupta 0573c17819 stream settings: Set weekly traffic to None instead of -1 for new streams.
The only place this gets used seems to be subscription.handlebars, where a
value of None (or null) is probably less broken-seeming than -1 anyway.

Sarah d1cda29fb4 API: Add stream email notification setting plumbing.
This is all the plumbing that makes it possible to enable the

doesn't do anything yet, but this is a nice checkpoint along the way
to implementing this feature.
