This adds a preview button to the subscriptions page to allow a user
to check out the stream without having to subscribe.
The button’s default state is hidden but on subscription row hover it
shows itself.
The preview button updates its text from "Narrow" to "Preview" and
back when a user subscribes and unsubscribes from a stream.
Fixes: #1519.
This fixes a bug where Zulip would throw a TypeError if the user were
to try to narrow to a stream they had never been subscribed to. With
the new "preview" feature on the subscriptions page, this will now
happen much more often.
This restructures the styling for the Zulip settings and
administration pages to minimize use of Bootstrap and use a consistent
styling library for similar elements.
While it is basically a wash in terms of the page's visuals, it will
make our life a lot easier for future work on improving the settings
pages section of the site.
This changes the JavaScript to fix the hash system to correctly save
state to allow a user to deep link to a particular app platform.
The mechanism is handled by a click event on #apps-tabs [data-toggle]
that fires a hash setter which then fires a hash getter which loads the
correct tab if necessary.
It appears that the assertRaisesRegexp approach we had before didn't
work properly on some systems, likely due to a bad interact with a
i18n (we haven't definitively determined the cause).
We now raise an exception in bugdown.do_convert() if rendering
fails, to avoid silent failures, and then calling code can convert
the exception to a JsonableError.
The list_to_streams() method now uses create_streams_if_needed() to
do its heavy lifting during the autocreate=True case.
This commit gets us to 100% coverage on the streams view. (The
recently created action.create_streams_if_needed() was easy
to test in isolation, and it has 100% coverage as well, so we are
not cheating here.)
Fixes: #1005.
