get_display_recipient's annotation clashes with other wrong annotations.
Fix those wrong annotations.
Since get_display_recipient returns a Union, use isinstance checks and
casts to make mypy checks succeed.
This changes the type annotations for the cache keys in Zulip to be
consistently text_type, and updates the annotations for values that
are used as cache keys across the codebase.
Add two options to the `test-backend` script:
1. verbose
If given the `test-backend` script will give detailed output.
2. no-shallow
Default value is False. If given the `test-backend` script will
fail if it finds a template which is shallow tested.
get_realm is better in two key ways:
* It uses memcached to fetch the data from the cache and thus is faster.
* It does a case-insensitive query and thus is more safe.
A stream is vacant when it has no subscribers and occupied when it has at least
one subscriber.
We have a slightly odd model where stream creation is conflated with
subscription creation. Streams are created by attempting to subscribe to a
stream that doesn't exist. We also hide streams with no subscribers from users
to make it seem like they've gone away. However, we can't actually remove those
streams because we want to preserve history.
This commit moves us towards a separation of these two concepts. By sending
events for stream creation, occupation, vacancy, and deletion, we allow clients
to directly observe the global state of streams rather than indirectly observing
subscription information. A more complete solution would involve adding a view
for explicitly creating streams without subscribing to them.
This commit does not handle the intricacies of invite-only streams. We
currently simply do not send these events for invite-only streams.
