My recent refactoring that split out MessageListData
introduced a nasty bug where we were putting muted
messages into the "All Messages" view even though
the underlying list was correctly filtering
them, so the symptoms were two-fold:
- muted messages cluttered up your feed
- replying to the message caused a traceback (since
it wasn't actually in the underlying data
structure)
This has to do with what MessageListData.add_messages()
was passing back to MessageList to orchestrate drawing
in MessageListView.
I think what happened here is I got this working kind
of sloppily but correctly for the non-muting case and
then got in the weeds of some other stuff. Not my
finest moment.
The actual correct code here is simple enough. We
triage top, interior, and bottom, and then the respective
methods that put the data into the data structure
return the filtered lists (i.e. not muted) and put them
into the info structure.
Fixes#9656
Before this change, the way to add messages had a lot
of ping-pong-ing between MessageList and MessageListData,
where first the data got triaged, but not actually
inserted into data structures, and then subsequent
calls would add the data and get filtered results.
Now we have a simple API for MessageListData.add_messages
that does all the data stuff up front. Having a fully
function MLD.add_messages not only makes the ML.add_messages
function about four lines shorter, it also sets us up
to easily build standalone MLD objects before making
the heavier ML objects.
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.)
