Since this does impact the ability to access the channel's content, it
makes sense to permit changing subscriptions, just like other
permissions settings on the archived channel.
This code path had not been properly updated for the new ways of
having content access to a channel.
Also adjust the error messages for missing content access.
Passing the user group object in case of named user group is fine for
`do_change_stream_group_based_setting`. But for anonymous groups, if the
code path calling that function is not creating a new anonymous user
group, it has to modify the user group by itself before calling that
function. In that case, if `old_setting_api_value` is not provided,
`old_user_group` is calculated false, since the group id has not changed
for the stream, but the group membership has changed.
old_setting_api_value will be the same as new_setting_api_value in such
a case.
It is better to accept the new setting value as either an int or
UserGroupMembersDict, so that `do_change_stream_group_based_setting` can
decide what to do with that argument.
We no longer archive private streams when they become vacant,
since user can still have permissions to subscribe to it.
And streams can anyways be archived manually if needed.
Fixes#33689.
This parameter is no longer restricted to realm administrators. Any
user can get the streams they have metadata access to by setting this
parameter to true.
We keep around the old `include_all_active` parameter for backwards
compatibility.
Web frontend doesn't use this API and thus there were no changes needed
there.
To get content access streams for mention.py, we will now use
get_content_access_streams and we have done a lot more other refactors
in this commit around filter_stream_authorization. Mainly making that
function only to be used for adding subscribers and naming it
accordingly.
This commit updates code to optimize computing users who have
metadata access via permission groups so that we do not have
to do DB query for each stream to get recursive members for
the groups having permissions.
Previously, when description for a channel -- either during its
creating or when we change its description contained a topic
permalink (through #-mention), then it was not rendered. This
is because of lack of authorization to access the channel.
This is fixed by passing the acting_user through the methods
which update or add the description, so that permissions
of the acting_user could be used to determine whether to
render the #-mention in stream description or not.
When a user gets access to a private channel, they get a stream creation
event. Channel admins and users in `can_add_subscribers_group` already
have metadata access to a private channel and therefore do not need to
be notified.

Non realm admin users were not able to view private channels they were
an administrator of but not subscribed to it. This commit changes that.
We also made changes for those users to be able to see the subscribers
list.
The increase in query count in test_home and test_event_system can be
mitigated by only fetching recursive user group ids when needed within
the `validate_user_access_to_subscribers_helper` function. But that
would require refactoring that function to handle multiple streams and
subscriptions at once, along with changing how that function is used at
different places, which might be an exercise better left as a follow up.
We have optimised the code a little bit by not fetching the group ids in
case the current user is a realm admin.
We are fetching channel_admin_ids and users belonging to
can_add_subscribers_group directly in stream_subscription.py without
using the helper function
`get_user_ids_with_metadata_access_via_permission_groups`. This is due
to a cyclic dependency and we will move `bulk_get_subscriber_peer_info`
to another file in the next commit.
Users in `can_administer_channel_group` and `can_add_subscribers_group`
have access to private channel metadata. They should be notified of
relevant events.
We've only made relevant changes to lib/streams.py in this commit to
make the changes small and reviewable.
Previously, realm and channel admins were not able to change settings
for a private channel they were not subscribed to. This commit changes
that.
We have only added the exception for can_add_subscribers_group
and not privacy settings.
We also need proper functions with proper terminologies for content
and metadata access.
We've also converted the function to check for permission to unsubscribe
others to accept a list of streams instead of checking each stream one
by one.
Previously, channel archival event messages were unread in
archived channels, which makes the archived channel accessible
from the inbox view.
This commit fixes this issue by auto-marking the channel archival
event message as read.
Fixes: zulip#33258.
This commit splits the existing deactivation test into two separate
tests — one for realm administrators and one for user group-based
permissions to improve clarity.
Fixes#32369
Migrate stream delete event to include only stream ids in the form of
"stream_ids": [1,...], because clients only need the ids.
While keep sending ids in the form of "streams": [{stream_id: 1},...]
for compatibility with all clients other than web.
The function to check relevant permissions does so for multiple streams
at once to save us database query counts. Doing it one by one for every
stream would become very expensive.
We've also added `insufficient_permission_streams` to the filter
functions return type for streams for which the current user does not
have permission to subscribe other users.
We remove `invite_to_stream_policy` from the backend wherever applicable
except deleting the field. We have just ported the existing behaviour of
`invite_to_stream_policy` to `can_add_subscribers_group` except one
change. We have added an explicit exception for admins to have this
permission whether they are part of this group or not. The reason for
this is we are adding `stream.can_add_susbcribers_group` in the future
which will grant all admins permission to subscribe other users to a
channel given they have access to a channel. So it makes sense that we
add this exception to the realm level property also.

This commit adds a `sender_id` parameter to the
`GET /streams/{stream_id}/email_address` endpoint to specify the
ID of a user or bot which should appear as the sender when messages
are sent to a channel using the channel email address.
Earlier, Email gateway bot was always the sender.
Fixes part of #31566.
This commit extracts the logic for creating or retrieving a channel
email token into a dedicated `get_channel_email_token` function.
This improves code clarity by decoupling token generation from
the email encoding process.
This commit is a part of the work to support empty string
as a topic name.
Previously, empty string was not a valid topic name.
Adds backward compatibility for topic names in `unread_msgs`
objects returned in `/register` response.
The stream and subscription objects now have stream_post_policy value
set according to the can_send_message_group setting representing the
superset of users who have permission to post in the channel.
