We did not send the stream creation events when subscribing
guests to public streams while we do send them when subscribing
non-admin users to private streams.
This commit adds code to send the stream creation events when
subscribing guests to public streams, so the clients can know
that the stream exists and fixes the bug where client tries
to process a subscription add event for a stream which it does
not know about.
This commit removes "@" from name of role-based system groups
since we have added a restricion on having user group names
starting with "@" in the previous commit as they look odd in
mention syntax.
We also add a migration in this commit to update the name of
role-based system groups in existing realms to remove "@"
from the name. This migration also updates the names of
non-system user groups by removing the invalid prefixes
from their names and if there is a group already with that
name, we insted name the group as "group:{group_id}".
Fixes#26148.
This changes bulk_get_streams so that it just uses the
database all the time. Also, we avoid calling
select_related(), so that we just get back thin and
tidy Stream objects with simple queries.
About not caching any more:
It's actually pretty rare that we fetch streams by name
in the main application. It's usually API requests that
send in stream names to find more info about streams.
It also turns out that for large queries (>= ~30 rows
for my measurements) it's more efficent to hit the
database than memcached. The database is super fast at
scale; it's just the startup cost of having Django
construct the query, and then having the database do
query planning or whatever, that slows us down. I don't
know the exact bottleneck, but you can clearly measure
that one-row queries are slow (on the order of a full
millisecond or so) but the marginal cost of additional
rows is minimal assuming you have a decent index (20
microseconds per row on my droplet).
All the query-count changes in the tests revolve around
unsubscribing somebody from a stream, and that's a
particularly odd use case for bulk_get_streams, since
you generally unsubscribe from a single stream at a
time. If there are some use cases where you do want to
unsubscribe from multiple streams, we should move
toward passing in stream ids, at least from the
application. And even if we don't do that, our cost for
most queries is a couple milliseconds.
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.
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.
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.
This commit renames the 'tornado_redirected_to_list' context
manager to 'capture_send_event_calls' to improve readability.
It also refactors the function to yield a list of events
instead of passing in a list data structure as a parameter
and appending events to it.
"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.

Since this function creates a new user group into the database,
it is more appropriate to have it not as a generic "lib" function
but as an "action".

The Django convention is for __repr__ to include the type and __str__
to omit it. In fact its default __repr__ implementation for models
automatically adds a type prefix to __str__, which has resulted in the
type being duplicated:

<UserProfile: <UserProfile: emailgateway@zulip.com <Realm: zulipinternal 1>>>

This commit renames reset_emails_in_zulip_realm function to
reset_email_visibility_to_everyone_in_zulip_realm which makes
it more clear to understand what the function actually does.
This commit also adds a comment explaining what this function
does.
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.
Black 23 enforces some slightly more specific rules about empty line
counts and redundant parenthesis removal, but the result is still
compatible with Black 22.
(This does not actually upgrade our Python environment to Black 23
yet.)

This guarantees that the Realm is always non-None when we hit the
codepath is_static_or_current_realm_url via
do_change_stream_description, so that we can properly skip rewritting
some images.

This adds a helper based on testing patterns of using the "queries_captured"
context manager with "assert_length" to check the number of queries
executed for preventing performance regression.
It explains the rationale of checking the query count through an
"AssertionError" and prints the queries captured as assert_length does,
but with a format optimized for displaying the queries in a more
readable manner.

Current value of can_remove_subscribers_group field is admins system group
only so behavior is not changed. We would provide support to change this
setting from API and UI in further commits.
This commit sets can_remove_subscribers_group to admins system
group while creating streams as it will be the default value
of this setting. In further we would provide an option to set
value of this setting to any user group while creating streams
using API or UI.
In Zulip 2.1.0, the `is_muted` stream subscription property was
added and replaced the `in_home_view` property. But the server has
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.
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.
We raise error when we try to change a public stream (except for
zephyr mirror realms) to be public with protected history, as we do
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.
This commit removes "role" field from subscription
objects since we are not moving forward with stream
administrator concept and instead working on new
permssions model as per #19525.
This commit removes the is_stream_admin property of Subscription
model and also updates check_stream_access_for_delete_or_update
to not return true when is_stream_admin is True.
We also removes the relevant tests.
This change is done as we would not be moving forward with the
stream administrator concept as we have decided to modify the
permissions model as per #19525.
Since `HttpResponse` is an inaccurate representation of the
monkey-patched response object returned by the Django test client, we
replace it with `_MonkeyPatchedWSGIResponse` as `TestHttpResponse`.
This replaces `HttpResponse` in zerver/tests, analytics/tests, coporate/tests,
zerver/lib/test_classes.py, and zerver/lib/test_helpers.py with
`TestHttpResponse`. Several files in zerver/tests are excluded
from this substitution.
This commit is auto-generated by a script, with manual adjustments on certain
files squashed into it.
This is a part of the django-stubs refactorings.

We have now decided to not continue with the stream administrator
concept as we are changing the permissions model to be based on
user groups as per #19525. So, this commit updates the error message
to "Must be an organization administrator".
This commit changes the error message from "Invalid stream id"
to "Invalid stream ID" for cases where invalid stream IDs are
passed to API endpoints to make it consistent with other similar
error messages.
We remove one call to get_occupied_streams to get occupied
streams before unsubscribing because we already know which
streams can become vacant, i.e. the one from which users are
being unsubscribed, and we can directly use the list of streams
from which users are being unsubscribed and get vacant streams
by checking which of these streams are not in get_occupied_streams
called after unsubscribing users.
Previously, we were marking messages of all the streams passed
to bulk_remove_subscriptions even if user was not subscribed
to some of them and those streams would ideally not have
any unread messages. This code was added in 766511e519.
This commit changes the code to only mark messages of actually
unsubscribed streams as read.
