This commit updates code to compute the values for group permission
settings in send_stream_creation_events_for_previously_inaccessible_streams
only when we need to send the events. This helps us in avoiding
unnecessary DB queries.
'compose_views' is used inside an outer db transaction created in
'update_user_group_backend'.
`transaction.atomic()` block in 'compose_views' resulted in
savepoint creation.
This commit adds `savepoint=False` to avoid that.
Streams should not be marked as private, and subscribers
of the deactivated stream should not be removed.
Update the confirmation message when archiving a stream.
`is_archived` field is added to the stream and types.
Include a new `archived_channeels` client capability, to allow clients
to access data on archived channels, without breaking
backwards-compatibility for existing clients that don't know how to
handle these.
Also, included `exclude_archived` parameter to `/get-streams`,
which defaults to `true` as basic clients may not be interested
in archived streams.
We create an unnamed user group with just the group creator as it's
member when trying to set the default. The pattern I've followed across
most of the acting_user additions is to just put the user declared
somewhere before the check_add_user_group and see if the test passes.
If it does not, then I'll look at what kind of user it needs to be set
to `acting_user`.
As part of our todo in the code, we want to use the unique user IDs
instead of emails when processing the results of subscribing users to a
channel. These changes apply those changes and streamlines the use of IDs.
Renamed event types below in the enum class to use channel instead of
stream.
Event types moved: STREAM_CREATED, STREAM_DEACTIVATED, STREAM_NAME_CHANGED
STREAM_REACTIVATED, STREAM_MESSAGE_RETENTION_DAYS_CHANGED
STREAM_PROPERTY_CHANGED, STREAM_GROUP_BASED_SETTING_CHANGED
Previously, this logic did the database queries to look up UserProfile
objects in a loop.
Fixes#21820.
Significantly improves Stream creation time and also unsusbcribing users.
Tested stream creation with 10k stream subscribers:
- before: 127 seconds ~2 mins
- after: 17 seconds ~0.3 min
Add a test case for user unsubscribing themself.
In 'test_subs' we were making POST request to add
subscrption using 'self.api_post'.
This commit updates the code to use the test helper
function 'common_subscribe_to_streams' instead.
This prep commit will also help us to avoid adding
'transaction.atomic' context manager to these API calls
individually in the case of error response in the next commit.
This commit updates code to prefetch realm group settings like
"can_create_public_channel_group" only when computing settings
for "/register" response by refetching the realm object with
select_related instead of fetching those settings in UserProfile
query.
This change is done because we do not need to prefetch these
settings for every UserProfile object and for most of the cases
where these settings are actually accessed, we can afford extra
query like when checking permission to create streams. But we
cannot afford one query extra for each setting when computing
these settings for "/register" response, so we re-fetch the
realm object with select_related leading to only one extra
query.
The query count changes in tests are -
- Query count increases by 1 when calling fetch_initial_state_data
for computing can_create_public_streams because Realm object from
UserProfile does not have prefetched setting fields.
- Query count increases by one in test_subs where streams are
created which is as expected due to the setting not being prefetched.
- Query count increases by 2 in tests in test_home.py where one
query is to refetch the realm object and one for computing
can_create_public_streams as mentioned above.
This commit removes create_public_stream_policy setting
since public channel creation permissions are now handled
by group-based setting.
We still pass "realm_create_public_stream_policy" in
"/register" response though for older clients with its
value being set depending on the value of group based
setting. If we cannot set its value to an appropriate
enum corresponding to the group setting, then we set
it to "Members only" considering that server will not
allow the users without permissions to create public
channels but the client can make sure that UI is
available to the users who have permission.
This commit updates code, majorly in tests, to use
setting values from enums instead of directly using
the constants defined in Realm.
We still have those constants defined Realm as they
are used in a couple of places where the same code
is used for different settings. These will be
handled later.
Earlier, we were using 'send_event' & 'queue_json_publish' in
'do_send_messages' which can lead to a situation where we enqueue
events but the transaction fails at a later stage.
Events should not be sent until we know we're not rolling back.
This is a follow-up to #29425. It assigns creator to three streams
that are used in tests and another two that aren't. For tests,
we assign a guest, an admin and an owner as creator.
Updates various areas of the backend code that generate
JsonableErrors with translated strings to use channel
instead of stream.
Part of stream to channel rename project.
In zerver/models/streams.py, updates translated string for when everyone
can post to a stream/channel to use channel instead of stream.
Part of stream to channel rename project.
In zerver/models/realms.py, updates the topic for stream/channel updates
to be "channel events" instead of "stream events".
Part of stream to channel rename project.
Updates notification messages that are sent to "stream events"
topic when a permission or policy setting is changed to use channel
instead of stream. Also, updates some strings that were not marked
for translation in the message that was sent when the retention
policy was changed.
Updates notification messages that are sent when a stream/channel
is created.
Updates notification messages that are sent when a user is
subscribed to stream/channel(s).
Part of stream to channel rename project.
Updates translated JsonableError strings that relate to streams
to use channel instead of stream. Separated from other error string
updates as this is a dense area of changes for this rename.
Part of stream to channel rename project.
Adds nullable creator field, containing a reference to the user who
created the stream. When creating a stream, acting user is set as
the creator of the stream. Since API calls to create streams always
have an acting user, this field should always be set when streams
are created using the API.
Because streams can be created with no acting user, this field is
nullable. We try to backfill existing streams using RealmAuditLog table,
but not all streams are guaranteed to have a recorded create log. Thus
this new field is left null when it cannot be backfilled. We also set
this field to null when the creator user is deleted.
This was only used in the undocumented narrow_stream mode, and relied
on a deprecated synchronous XHR request.

This commit renames the realm-level setting 'notifications_stream'
to 'new_stream_announcements_stream'.
The new name reflects better what the setting does.
This commit adds code to send stream deletion events when
unsubscribing non-admin users from private streams and
when unsubscribing guests from public streams since
non-admins cannot access unsubscribed private streams
and guests cannot access unsubscribed public streams.
