We pass in sub instead of stream_name, to support callers that
already do lookups by stream id.
And then we make the second optional argument be subscribers, since
that is all we were using from the old `attrs` argument.
When possible, we should use get_sub_from_target() instead of
get_stream_name(), not only because it often saves a lookup later,
but it also makes it easier to audit the code for name vs. id
bugs. (When you rename a stream, there can be races where you
use the old stream name instead of the more durable stream_id).
This commit handles the easy cases where the caller directly
wanted the sub, not the name.
A clear-search option to clear the user-list searchbox has been added.
This feature was present in the main searchbar but absent elsewhere.
Fix a part of #3716.
We had a theory that get_user_id() errors were often due to race
conditions related to reloads, so we would only report missing
user ids if subsequent lookups failed 5 seconds later. It turns
out we still get the blueslip errors, and now we don't get
meaningful tracebacks. This change makes it so that errors
get reported immediately again.
If we get invalid events related to stream subscribers, we now
exit earlier to prevent ugly tracebacks. We may eventually
want to upgrade some of these warnings to errors, once we fix some
of our live-update bugs. In particular, we don't yet live-update
users when streams go from private to public, so if you add/remove
subscribers to a newly-public stream that a user still thinks is
private, they will not be able to handle the event through no
fault of the codepath that happens during the add/remove.
This currently only supports this in emoji reactions, not in actual
emoji in message bodies, but it's a great start for people who want a
text-only view.
Tweaked to update the text by tabbott.
Fixes#3169.
We have special code for closing a "compose preview", but
it should only apply to the enter key. Before this fix, we
would do the "enter" logic for other hotkeys like "j".
If you are typing a key like "q" in the compose box, there is no
need to check if the home tab is obscured, because the effect of
"q" is not limited by the message pane being opened.
This saves a bit of unnecessary computation when you type
non-arrow keys, which is especially important in the compose
box for characters that seem ordinary, like "j" and "q", but
which have mappings in some cases.
I noticed while reviewing #3807 that we still haven't fixed this;
because timestamps are primarily displayed in the message view, fixing
this is trivial.
Apparently, our logic was broken on systems where altKey and metaKey
are different, because we didn't ignore hotkey combinations that
included altKey.
Fixes#3738.
Change `from django.utils.timezone import now` to
`from django.utils import timezone`.
This is both because now() is ambiguous (could be datetime.datetime.now),
and more importantly to make it easier to write a lint rule against
datetime.datetime.now().
