When you unsubscribe a stream by clicking on the
checkmark, we don't want it to disappear right
away, but we also don't need it to stay around
once you start searching for new streams.
Note from Tim: This commit removes some complex code that was just a
workaround for the fact that this widget used to automatically
re-filter immediately after clicking to unsubscribe a user.
Since we've since fixed that original issue, we don't need this.
We probably should have done this a while ago, even
though these functions are pretty tiny. The goal here
is to make it easier to have more consistent search
semantics.
Our first use case is subs.js. In this case we
are able to decouple a bit of generic string
matching from the subs-specific code.
We move some data code from subs.js to stream_data.js.
It's not clear we have been using the optimal sort for
dealing with locales, but this change preserves the
current behavior. The only subtle change here is that
we look up subs using a Dict now instead of a plain
JS object.
This is preparation for our migration of our JS pipeline to webpack,
which includes as part of the process a hack of exporting globals via
the window object.
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.)
User search for streams will now return results where the stream
description (but not the stream name) include the string in the
user query.
The filtering process first obtains the streams whose names match the
user search query, then sorts and displays them. From the remaining
streams, it obtains streams whose description matches the query and
displays them in sorted order after the name match results. Other
streams are not displayed.
Fixes: #2674.
When filtering streams, we were incorrectly treating the regexp input
provided by the user as a regular expression, meaning that terms like
`c++` would trigger errors because they are invalid regular expression
syntax. We fix this by replacing RegExp with a simple IndexOf check.
Node test added by tabbott.
Fixes#3559.
