This seems like a small change (apart from all the
test changes), but it fundamentally changes how
the app finds "topic" on message objects. Now
all code that used to set "subject" now sets "topic"
on message-like objects. We convert incoming messages
to have topic, and we write to "topic" all the way up
to hitting the server (which now accepts "topic" on
incoming endpoints).
We fall back to subject as needed, but the code will
emit a warning that should be heeded--the "subject"
field is prone to becoming stale for things like
topic changes.
We now have two functions:
add_new_messages
add_old_messages
This is a lot easier on the eyes, and it will also
prevent us from exceeding line length in future commits.
We also remove an unneeded stub in the narrow_activate
tests.
If you zoom into "more topics" for a stream that has
a LOT of topics, and then scroll down to the bottom,
and then zoom out by selecting "All messages" or
similar upper-left-sidebar options, we now try to scroll
the more recently active stream back into place after we scroll
out.
Before this change, it was possible for your lower left
sidebar to appear empty, as it would keep the
scroll offset from "more topics".
If our topic list isn't zoomed in, avoid calling
stream_list.zoom_out_topics().
This commit also introduces `zoomed_in` to track
our topic zooming state.
This small modules nicely breaks down the
responsibilities of topic_list and stream_list
when it comes to zooming in and out of topics
(also known as hitting "more topics" or "All
Streams).
Before this, neither module was clearly in
charge, and there were kind of complicated
callback mechanisms. The stream_list code
was asking topic_list to create click handlers
that called back into stream_list.
Now we just topic_zoom set up its own click
handlers and delegate out to the other two
modules.
This replaces some old code with calls to topic_data.js.
Now our topic typeahead uses the same data as our
sidebar, stream suggestions, and the "n" key, so any
future improvements to that data will benefit all
features the same.
This is an important piece of #9857.
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.)
The new list_cursor class is more generic and saves the state
of your cursor across redraws.
Note that we no longer cycle from bottom to top or vice versa.
The node test code that was removed here was kind of complex
and didn't actually assert useful things after calling methods.
This node test module is intended as a way for somebody to
quickly immerse themselves in our node testing methodologies,
plus it has the nice side effect of introducing several modules
(albeit very briefly).
