This makes a few important cleanup changes:
* Using the more standard data-field-id name for the ID value.
* Using $(e.target).closest() rather than `.parent`, which is more
robust to future changes in markup.
Most of this was straightforward.
Most functions that were grabbed verbatim and whole from
the original class still have one-line wrappers.
Many functions are just-the-data versions of functions that
remain in MessageList: see add, append, prepend, remove as
examples. In a typical pattern the MessageList code becomes
super simple:
prepend: function MessageList_prepend(messages) {
var viewable_messages = this.data.prepend(messages);
this.view.prepend(viewable_messages);
},
Two large functions had some minor surgery:
triage_messages =
top half of add_messages +
API to pass three lists back
change_message_id =
original version +
two simple callbacks to list
For the function update_muting_and_rerender(), we continue
to early-exit if this.muting_enabled is false, and we copied
that same defensive check to the new function
named update_items_for_muting(), even though it's technically
hidden from that codepath by the caller.
Even though starred messages are never unread, it's useful
for us to have helper functions for them.
This change makes it so that clicking on "Starred Messages"
takes you to the last read message immediately, without a
server delay.
This fixes some minor glitches with buttons:
* Movement of the organization-settings-parent block on the
appearance of widgets.
* Large and odd look of save button.
* Use of fadeIn and fadeOut rather than changing opacity as
opacity don't actually remove them.
If notifications_stream is private and the current user has never been
subscribed, then we would throw an exception when trying to look up
notifications_stream. In this situation, we should just treat it like
the stream doesn't exist for the purposes of this user.
The original version of this function was simulating kind
of an illogical code path, where -1 was sort of pointing to
a real message, which doesn't make sense.
Now we pass in an explicit then_select_id.
Here `file.lastModified` is unique for each upload so it is used
to track each upload individually.
Also, we have used `uploadStarted` function because it is
called for each file during an upload.
Fixes: #9068.
This takes advantage of the new function narrow_state.stream_id().
We now assume the incoming stream_id is a valid stream_id, so we
no longer need to test some of the error checking. (It's possible that
the incoming stream_id may no longer be for a stream you subscribe
to, but the nice benefit of working more in "id space" is that if
it doesn't match the narrow's stream id, we know false is a safe
return value.)
After adding a newly created stream to the top of the stream list,
call to actually_filter_streams in stream_events.mark_subscribed
rerendered the filter_table and the stream list was refreshed. The
call to actually_filter streams was introduced to rerender the
subscriber list but stream_edit.rerender_subscribers_list takes care
of it already.
Fixes#9033.
Instead of treating false differently from undefined, our
function is now a regular boolean function, and we limit our
code comments to the one corner case where the true/false
decision is kind of arbitrary and possibly confusing.
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.
