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.

Mateusz Mandera d91d3a05b9 tests: Use do_create_realm where possible.
Using do_create_realm should be preferred over manual creation where
possible, as it creates more realistic data.

sahil839 4ca21a6982 users: Give moderators same permissions as that of full members.
This commit updates the stream creation, subscribing others to
stream, wildcard mention settings and stream post policy to allow
realm moderators even if they are new and the respective setting
is set to allow full members only.

This commit renames the is_new_member property in models.py

who is not a full member. We will add a condition in further
commit such that this returns 'False' for a moderator as we
will initially give all the rights to moderator that a full
member has.

Mateusz Mandera bf9e5e52ce dependencies: Upgrade to Django 3.0.
Adjustments made due to changes in Django 3.0:
(https://docs.djangoproject.com/en/3.0/releases/3.0/)

- test_signup: INTERNAL_RESET_URL_TOKEN was moved to
  PasswordResetConfirmView.reset_url_token
- test_message_fetch:
  "add_never_cache_headers() and never_cache() now add the private
  directive to Cache-Control headers."
- "django.utils.html.escape() now uses html.escape() to escape HTML.
  This converts ' to &#x27; instead of the previous equivalent decimal
  code &#39;." - this requires adjusting the expected decimal code
  in some of the string fixtures in tests.

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.

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

The extra queries here are due to the fact

of O(N) overhead.  We may be able to bulk-fetch
these users eventually.

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)

Note that this only affects the webapp, as mobile/ZT
don't use this.

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

    self.login_user(hamlet)

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

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`.

a prep commit for something along those
lines, kind of hard to explain the full
plan.)

This commit includes a new `stream_post_policy` setting,

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.

Rohitt Vashishtha b69213808a messages: Render topic links in context of stream realm.
Priviously, we rendered the topic links using the msg.sender.realm.
This resulted in issues with Zulip's internal bots not having access
to the realm_filters of the destination stream's realm. For example,
sending a message via the email gateway or notification would not
linkify any realm filters that a user would expect them to.

Mateusz Mandera 26f7dd09ce display_recipient: Eliminate raw_display_recipient from message dicts.
This was used as a helper to construct the final display_recipient when
fetching messages. With the new mechanism of constructing

database and cache, this shouldn't be needed anymore.

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).

Fixes #12818.

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.

Hemanth V. Alluri ede73ee4cd streams: New stream messages should be auto marked as read by creator.
When a person creates a new realm, they'll likely want to create a
bunch of initial streams at once. When doing so, it could be annoying
to have to mark all of the new stream notification messages as read.

Thus to make this process smoother, we should automatically mark
the messages generated by the Notification Bot in the notifications
(announcements) stream, as well as in the newly created stream itself
as read by the stream creator.

Fixes #12765.

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.

A key part of this is the new helper, get_user_by_delivery_email.  Its

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.

Jack Weatherilt d857f26cd3 refactoring: Remove unused assignment on ensure_stream.
There were two instances of `ensure_stream` being called and assigned to
a variable with the variable not being used elsewhere. pyflakes picked
up on this (where it didn't in the previous version likely due to tuple
unpacking), so the the variable assignment has been replaced with a call
to `ensure_stream`.

Jack Weatherilt 3396cfc2ef refactoring: Replaced occurences of create_stream_if_needed.
Issue #2088 asked for a wrapper to be created for
`create_stream_if_needed` (called `ensure_stream`) for the 25 times that
`create_stream_if_needed` is called and ignores whether the stream was
created. This commit replaces relevant occurences of
`create_stream_if_needed` with `ensure_stream`, including imports.

The changes weren't significant enough to add any tests or do any
additional manual testing.

The refactoring intended to make the API easier to use in most cases.
The majority of uses of `create_stream_if_needed` ignored the second
parameter.

Fixes: #2088.

YJDave 72a440a86d stream settings: Fix error in real time sync in subs add/remove event.
Currently, when other private stream subscriber add realm admin to
stream, new copy private stream is created in realm admin's streams.
Which resulted in error, cause there are two similar stream element
in stream settings.

If new subscriber is added to private stream, we first send them
stream `create` event, cause private stream are not visible until
user don't get subscribed at least once. But realm admins can now
always access private stream, so when realm admin is subscribed to
stream, realm admin get stream `create` event even if stream already
exist in on realm admin client side.

Fix this by extracting realm admins from stream `create` event on
`add` subscription operation and sending private stream `create`
event to all realm admins on stream creation operation.

YJDave 382ac24151 create stream: Fix real time sync bug in private stream creation.
If new private stream is created by realm admin without realm admin
subscribed to it, then it doesn't automatically add created stream to
realm admin's stream list. We have to reload the browser to get newly
created stream in stream list. Cause private stream creation event is
only sent to the subscribed users to private stream, so even if realm
admin is acting user, they don't get creation event.

We should send private stream creation event to realm admin users along
with subscribed user to stream, as realm admins can access unsubscribed
private streams.

Tweaked by tabbott to fix various typos and clean up the code.

Steve Howell 46a49777c4 Add stream ids to urls for stream-related narrows.
This commit prefixes stream names in urls with stream ids,
so that the urls don't break when we rename streams.

strean name: foo bar.com%
before: #narrow/stream/foo.20bar.2Ecom.25
after: #narrow/stream/20-foo-bar.2Ecom.25

For new realms, everything is simple under the new scheme, since
we just parse out the stream id every time to figure out where
to narrow.

For old realms, any old URLs will still work under the new scheme,
assuming the stream hasn't been renamed (and of course old urls
wouldn't have survived stream renaming in the first place).  The one
exception is the hopefully rare case of a stream name starting with
something like "99-" and colliding with another stream whose id is 99.

The way that we enocde the stream name portion of the URL is kind
of unimportant now, since we really only look at the stream id, but
we still want a safe encoding of the name that is mostly human
readable, so we now convert spaces to dashes in the stream name.  Also,
we try to ensure more code on both sides (frontend and backend) calls
common functions to do the encoding.

Tim Abbott b2cb443d24 subs: Fix clearing unread counts when leaving private streams.
Because we use access_stream_by_id here, and that checks for an active
subscription to interact with a private stream, this didn't work.

The correct fix to add an option to active_stream_by_id to accept an
argument indicating whether we need an active subscription; for this
use case, we definitely do not.

Vishnu Ks 766511e519 actions: Mark all messages as read when user unsubscribes from stream.
This fixes a bug where, when a user is unsubscribed from a stream,
they might have unread messages on that stream leak.  While it might
seem to be a minor problem, it can cause significant problems for
computing the `unread_msgs` data structures, since it means we need to
add an extra filter for whether the user is still subscribed, either
in the backend or in the UI.

Fixes #7095.

Steve Howell faba34dae4 Simplify bulk_remove_subscriptions().
We extract get_bulk_stream_subscriber_info() from this
function to remove some of the complexity.  Also, in that
new function we avoid a hop to the database by querying
on stream ids instead of recipient ids.  The query that
gets changed here does require a join to the recipient
table (to get the stream id), so it's a little bit of a
tradeoff.

The first method we extract to this library is

is slightly annoying (having the method on Stream was nice)

Steve Howell 635675fe48 Reduce queries needed for sending messages.
In do_send_messages, we only produce one dictionary for
the event queues, instead of different flavors for text
vs. html.  This prevents two unnecessary queries to the
database.

It also means we only put one dictionary on the "message"
event queue instead of two, albeit a wider one that has
some values that won't be sent to the actual clients.

This wider dictionary from MessageDict.wide_dict is also
used for the `feedback_messages` queue and service bot
queues.  Since the extra fields are possibly useful down
the road, and they'll just be ignored for now, we don't
bother to remove them.  Also, those queue processors won't
have access to `content_type`, which they shouldn't need.

Steve Howell a6ad9a6d7c Add is_zephyr to the Stream model.
Add this field to the Stream model will prevent us from having
to look at realm data for several types of stream operations, which

our cached data bloated.

Going forward, we'll set stream.is_zephyr to True whenever the
realm's string id is "zephyr".

Steve Howell 7c726a5e77 Remove sender names from the message cache.
This removes sender names from the message cache, since
they aren't guaranteed to be valid, and they're inexpensive
to add.

This commit will make the message cache entries smaller
by removing sender___full_name and sender__short_name
fields.

Then we add in the sender fields to the message payloads
by doing a query against the unique sender ids of the
messages we are processing.

This change leads to 2 extra database hops for most of
our message-related codepaths.  The reason there are 2 hops
instead of 1 is that we basically re-calculate way too
much data to get a no-markdown dictionary.

Steve Howell 428d3027c2 Only require ids for finding DefaultStream objects.
We don't need full Realm objects to find DefaultStream
objects for a realm.  So now a few functions related to
adding/removing default streams use realm_id for lookups.

Similarly, we don't need a full Stream object to find
out if a stream exists in DefaultStream, so we do id
lookups there as well.

This sets us up to use thinner objects in callers.

Steve Howell 8ad7133351 Cache active_user_ids() more directly.
We now have a dedicated cache for active_user_ids() that only
stores a list of user_ids.

Before this commit, active_user_ids() used a cache of UserProfile
dictionaries, so it incurred unnecessary deserialization costs for
all the user fields that it sliced away in a list comprehension.

Because the cache is skinnier here, we also need to invalidate it
less frequently.  Basically, all we care about is new users, realm
deactivations, and user deactivations.

It's hard to measure how much this will improve performance, because
the speedup for any operation here is pretty minor, but we use this
function a lot, so hopefully it will make the overall system more
healthy.

Steve Howell 1553dc00e0 Introduce StreamRecipient class.
This class encapsulates the mapping of stream ids to

repeated use (i.e. it remembers values it already fetched).

This particular commit barely improves the performance
of gather_subscriptions_helper, but it sets us up for
further optimizations.

Long term, we may try to denormalize stream_id on to the
Subscriber table or otherwise modify the database so we
don't have to jump through hoops to do this kind of mapping.
This commit will help enable those changes, because we
isolate the mapping to this one new class.
