Steve Howell d6ef94f63f page load: Improve default_streams performance.
At least as measured by test_events.py, which has over 1000
calls to fetch initial data for page loads, this should
be about a 10% improvement in how much time the server
spends fetching data.

We mostly avoid a select_related() query that did this nastiness:

    INNER JOIN "zerver_realm" ON ("zerver_stream"."realm_id" = "zerver_realm"."id")
    INNER JOIN "zerver_usergroup" ON ("zerver_stream"."can_remove_subscribers_group_id" = "zerver_usergroup"."id")
    INNER JOIN "zerver_realm" T4 ON ("zerver_usergroup"."realm_id" = T4."id")
    INNER JOIN "zerver_usergroup" T5 ON ("zerver_usergroup"."can_mention_group_id" = T5."id")
    INNER JOIN "zerver_realm" T6 ON (T5."realm_id" = T6."id")
    INNER JOIN "zerver_usergroup" T7 ON (T5."can_mention_group_id" = T7."id")
    INNER JOIN "zerver_realm" T8 ON (T7."realm_id" = T8."id")
    INNER JOIN "zerver_usergroup" T9 ON (T7."can_mention_group_id" = T9."id")
    INNER JOIN "zerver_realm" T10 ON (T9."realm_id" = T10."id")
    INNER JOIN "zerver_usergroup" T11 ON (T9."can_mention_group_id" = T11."id")
    WHERE "zerver_stream"."id" IN (SELECT U0."stream_id" FROM "zerver_defaultstream" U0 WHERE U0."realm_id" = 2

Future commits will address the codepath for creating users.

Steve Howell 763b5e0741 default streams: Extract library functions.
I created zerver/lib/default_streams.py, so that various
views and events.py don't have to awkwardly reach into
an "actions" file.

I copied over two functions verbatim from actions/default_streams.py:

    get_default_streams_for_realm
    streams_to_dicts_sorted

The latter only remains as an internal detail in the new library.

I also created two new helpers:

    get_default_stream_ids_for_realm:

        This is both faster and easier to use in all the places
        where we only need to get a set of default stream ids.

    get_default_streams_for_realm_as_dicts:

        This just wraps the prior calls to
        streams_to_dicts_sorted(get_default_streams_for_realm(...)),
        and it doesn't yet address the slowness of the underlying
        code.

        All the "real" code should be functionally the same.

        In a few tests I now use this wrapper instead of
        calling get_default_streams_for_realm, just to get
        slightly deeper coverage.

Ujjawal Modi 2a6146110c subscriptions: Change in API used for adding new subscriptions.
Earlier when a user who is not allowed to add subscribers to a
stream because of realm level setting "Who can add users to streams"
is subscribing other users while creating a new stream than new stream
was created but no one is subscribed to stream.

To fix this issue this commit makes changes in the API used
for adding subscriptions. Now stream will be created only when user
has permissions to add other users.

With a rewrite of the test by Tim Abbott.

Zixuan James Li e331c356e4 user_groups: Use check_add_user_group instead in test cases.
"check_add_user_group" is a safer helper function than
"create_user_group" to use when creating user_groups. It does
error handling and notify the client with the appropriate event.

Note that the populate_db command still uses "create_user_group"
because we do not need to enqueue events at that point.

Anders Kaseorg 2d9b2a2a05 models: Remove type prefixes from __str__ values.
The Django convention is for __repr__ to include the type and __str__

Sahil Batra 0cf99cf5c3 streams: Refactor code to set group-based stream settings.
We add stream_permission_group_settings object which is
similar to property_types framework used for realm settings.

This commit also adds GroupPermissionSetting dataclass for
defining settings inside stream_permission_group_settings.

We add "do_change_stream_group_based_setting" function which
is called in loop to update all the group-based stream settings
and it is now used to update 'can_remove_subscribers_group'
setting instead of "do_change_can_remove_subscribers_group".

We also change the variable name for event_type field of
RealmAuditLog objects to STREAM_GROUP_BASED_SETTING_CHANGED
since this will be used for all group-based stream settings.

'property' field is also added to extra_data field to identify
the setting for which RealmAuditLog object was created.

We will add a migration in further commits which will add the
property field to existing RealmAuditLog objects created for
changing can_remove_subscribers_group setting.

In Zulip 2.1.0, the `is_muted` stream subscription property was

still only been sending subscription update events with the
`in_home_view` property.

Updates `do_change_subscription_property` to send a subscription
update event for both `is_muted` and `in_home_view`, so that
clients can fully migrate away from using `in_home_view` allowing
us to eventually remove it completely.

Sahil Batra 3e6463804e streams: Allow changing history access without is_private parameter.
We now allow changing access to history of the stream by only passing
"history_public_to_subscribers" parameter. Previously, "is_private"
parameter was also required to change history_public_to_subscribers
otherwise the request was silently ignored.

We also raise error when only history_public_to_subscribers parameter
is passed with value False without "is_private: True" for a public
or web-public stream since we do not allow public streams with
protected history.

Sahil Batra 6ccfebac56 streams: Raise error when making public stream with private history.
We raise error when we try to change a public stream (except for

not support such streams yet.

Previously, in such case we changed nothing and a notification was
sent to the "stream events" topic with message being "stream is
changed from public to public" and was weird.

Note that this commit only handles the case when both is_private and
history_public_to_subscribers parameters are passed to API and commit
not covers the case when only "history_public_to_subscribers" with
value False is passed to API, since we currently ignore requests
which has only history_public_to_subscribers parameter with not None
and not is_private and is_web_public.
We would do this in further commits when we add support for accepting
only history_public_to_subscribers parameter.

Tim Abbott d149af936d models: Rework Attachment.is_*_public to be a cache.
Previously, Attachment.is_realm_public and its cousin,
Attachment.is_web_public, were properties that began as False and
transitioned to True only when a message containing a link to the
attachment was sent to the appropriate class of stream, or such a link
was added as part of editing a message.

This pattern meant that neither field was updated in situations where
the access permissions for a message changed:

* Moving the message to a different stream.
* Changing the permissions for a stream containing links to the message.

This correctness issue has limited security impact, because uploaded
files are secured both by a random URL and by these access checks.

To fix this, we reformulate these fields as a cache, with code paths
that change the permissions affecting an attachment responsible for
setting these values to the `None` (uncached) state. We prefer setting
this `None` state over computing the correct permissions, because the
correct post-edit permissions are a function of all messages
containing the attachment, and we don't want to be responsible for
fetching all of those messages in the edit code paths.

Adds request as a parameter to json_success as a refactor towards

Also, removes any data parameters that are an empty dict or
a dict with the generic success response values.

Eeshan Garg 0d99809fd3 streams: Add notifications for permission policy changes.
The change to curl_param_value_generators.py warrants a brief
explanation. Stream permission changes now generate a notification
message. Our curl example test for removing a reaction comes after
the two tests for updating the stream permission changes, thus the
hardcoded message ID in that test needs to be incremented by 2 to
account for the two notification messages that now come before it.

This is a part of #20289.

Steve Howell dd1c9c45c7 stream colors: Try harder to avoid collisions.
We now use recipient_id % 24 for new stream colors
when users have already used all 24 of our canned
colors.

This fix doesn't address the scenario that somebody
dislikes one of our current canned colors, so if a
user continually changes canned color N to some other
color for new streams, their new streams will continue
to include color N (and the user will still need to
change them).

This fix doesn't address the fact that it can be expensive
during bulk-add situations to query for all the colors
that users have already used up.

See https://chat.zulip.org/#narrow/stream/3-backend/topic/assigning.20stream.20colors

Eeshan Garg c30458e174 streams: Add notifications for posting policy changes.
An explanatory note on the changes in zulip.yaml and
curl_param_value_generators is warranted here. In our automated
tests for our curl examples, the test for the API endpoint that
changes the posting permissions of a stream comes before our
existing curl test for adding message reactions.

Since there is an extra notification message due to the change in
posting permissions, the message IDs used in tests that come after
need to be incremented by 1.

This is a part of #20289.

Steve Howell a9271e7a99 performance: Cache stream lookups in MentionBackend.
This is useful when you subscribe a bunch of folks
to a stream and need to send them all PMs telling
them about the new subscription.
2021-12-30 11:28:15 -08:00
Steve Howell c4bd4496dd peformance: Cache user mentions for multiple PMs.
It's slightly annoying to plumb Optional[MentionBackend]
down the stack, but it's a one-time change.

I tried to make the cache code relatively unobtrusive
for the single-message use case.

We should be able to eliminate redundant stream queries
using similar techniques.

I considered caching at the level of rendering the message
itself, but this involves nearly as much plumbing, and
you have to account for the fact that several users on
your realm may have distinct default languages (French,
Spanish, Russian, etc.), so you would not eliminate as
many query hops. Also, if multiple streams were involved,
users would get slightly different messages based on
their prior subscriptions.

Steve Howell 966d88a78a stream colors: Fix stream color assignment.
The bug here probably didn't come up too much in
practice, but if we were adding a user to multiple
streams when they already had used all N available
colors, all the new streams would be assigned the same
color, since the size of used_colors would stay at N,
thwarting our little modulo-len hackery.

It's not a terrible bug, since users can obviously
customize their stream colors as they see fit.

Usually when we are adding a user to multiple streams,
the users are fairly new, and thus don't have many
existing streams, so I have never heard this bug
reported in the field.

Anyway, assigning the colors in bulk seems to make more
sense, and I added some tests.

For the situations where all the colors have already
been used, I didn't put a ton of thought into exactly
which repeated colors we want to choose; instead, I
just ensure they're different modulo 24. It's possible
that we should just have more than 24 canned colors, or
we should just assign the same default color every time
and let users change it themselves (once they've gone
beyond the 24, to be clear). Or maybe we can just do
something smarter here. I don't have enough time for a
deep dive on this issue.

Steve Howell f638fd6f72 performance: Get used stream colors in separate trip.
This commit sets us up for the next commit, which will
save us a very expensive query.

If you are adding 15k users to a stream, and each user
has about 20 existing streams, then we need to retrieve
300k rows from the database to figure out which stream
colors they already have.  We don't need all the extra
fields from Subscription, so now we get just the two
values we need for making a color map.

In the next commit we'll eliminate the other use case
for the big query, and I will explain in greater
depth how splitting out the color-picking code can
be a huge win. It is possible that some product decisions
could make this codepath easier. We could also do some
engineering specific to stream colors, such as caching
which colors users have already used.

This does cost us an extra round trip to the database.

Steve Howell 2902f8b931 tests: Ensure stream senders get a UserMessage row.
We now complain if a test author sends a stream message
that does not result in the sender getting a
UserMessage row for the message.

This is basically 100% equivalent to complaining that
the author failed to subscribe the sender to the stream
as part of the test setup, as far as I can tell, so the
AssertionError instructs the author to subscribe the
sender to the stream.

We exempt bots from this check, although it is
plausible we should only exempt the system bots like
the notification bot.

I considered auto-subscribing the sender to the stream,
but that can be a little more expensive than the
current check, and we generally want test setup to be
explicit.

If there is some legitimate way than a subscribed human
sender can't get a UserMessage, then we probably want
an explicit test for that, or we may want to change the
backend to just write a UserMessage row in that
hypothetical situation.

For most tests, including almost all the ones fixed
here, the author just wants their test setup to
realistically reflect normal operation, and often devs
may not realize that Cordelia is not subscribed to
Denmark or not realize that Hamlet is not subscribed to
Scotland.

Some of us don't remember our Shakespeare from high
school, and our stream subscriptions don't even
necessarily reflect which countries the Bard placed his
characters in.

There may also be some legitimate use case where an
author wants to simulate sending a message to an
unsubscribed stream, but for those edge cases, they can
always set allow_unsubscribed_sender to True.

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.
