This a check on server side to verify whether the user sending request
to create stream where only admins can post is an admin or not; Raises
a JsonableError when the user is not the realm admin.
This fixes a bug where administrators couldn't remove private
unsubscribed streams from the "default streams" list, because
access_stream_by_name didn't give them access to the stream object.
We don't indend for this server-level setting to exist in the long
term; the purpose of this is just to make it easy to test this code
path for development purposes.
This implements much of the Message side part of #2745.
The new name can_access_stream_history_by_name gets to the point of
what this function actually does. And passing in a user object lets
us define what this does based on the user subscribed.
This will allow realm admins to access subscribers of unsubscribed
private stream. This is a preparatory commit for letting realm admins
remove those users.
This will allow realm admins to update the names and descriptions of
private streams even if they are not subscribed, which fixes the buggy
behavior that previously nobody could(!).
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.
Do you call get_recipient(Recipient.STREAM, stream_id) or
get_recipient(stream_id, Recipient.STREAM)? I could never
remember, and it was not very type safe, since both parameters
are integers.
This commit completely switches us over to using a
dedicated model called MutedTopic to track which topics
a user has muted.
This includes the necessary migrations to create the
table and populate it from legacy data in UserProfile.
A subsequent commit will actually remove the old field
in UserProfile.
This makes get_stream match get_realm, get_user_profile_by_email,
etc., in interface, and is more convenient for mypy annotations
because `get_stream` now doesn't return an Optional[Stream].
The goal of this library is to make it a lot easier to prevent bugs
like CVE-2017-0881 by having all of our views logic for fetching a
stream go through a couple carefully tested code paths.
