This run_test helper sets up a convention that allows
us to give really short tracebacks for errors, and
eventually we can have more control over running
individual tests. (The latter goal has some
complications, since we often intentionally leak
setup in tests.)
Instead of treating false differently from undefined, our
function is now a regular boolean function, and we limit our
code comments to the one corner case where the true/false
decision is kind of arbitrary and possibly confusing.
In stream settings, if user add subscriber to unsubscribed public
stream from `Add` input widget it gives lots of blueslip warnings,
cause user isn't subscribed to public stream.
Fix this by changing condition to `sub.can_access_subscriber` from
`sub.subscribed` in blueslip warning, cause user can access
subscribers in such cases even if not subscribed to stream.
Tweaked by tabbott to make the node tests pass.
Using stream_id in recipient comparisons fixes a
bug in this scenario: go to home view, send message
to stream, wait for admin to rename stream, send
another message to the stream. Before this change,
the stream name would live-update but you'd get a
spurious recipient bar due to the prior message still
having the old stream name in places internally.
There were other ways to fix the live-update glitch,
but it's just generally cleaner to do stream id
comparisons.
Part of this change is to add stream_id to
compose_fade.set_focused_recipient().
