This is purely to make it easier to read narrow.activate()
without having to page past lots of unnecessary detail when
you're trying to understand things like how we set the
selection.
The maybe_select_closest helper, when first introduced, was
tiny and close to its callers.
As it's grown, it's become kind of a big hurdle to reading
narrow.activate(), because it's out of chronological order
and it's hard to tell at a glance which variables it's closing
on.
Now we just move it out to module scope.
It's mostly moving code, with these minor changes:
* we pass in opts for the old closure vars
* we rename then_select_offset -> select_offset
* we early-exit on empty lists
We replace these variables in narrow.activate:
then_select_id (int w/-1 as a sentinel)
select_first_unread (boolean)
The main goal here is to get away from the boolean, since
we are about to introduce a third select strategy.
The new var is select_strategy and it has a union
type with these flavors:
"exact" (was select_first_unread === false)
"first_unread" (was select_first_unread === true)
The new flavor will be something like "last_id".
Eliminating then_select_id is also nice, since the -1
sentinel value could be a pitfall, and it's semantically
cleaner to encapsulate behind a check for
select_strategy.flavor.
We use an IIFE (immediately invoked function expression)
to fetch messages. This will allow us to introduce some
local vars in a subsequent commit without creating an ugly
diff and without cluttering an already crowded namespace.
This cleans up a subsequent diff. Within the context of
`maybe_select_closest`, there's only one `msg_id` we care about,
so the more convoluted name `then_select_id` makes much less
sense than it does in the enclosing scope, and it will make
even less sense after some future changes.
There's also some cosmetic cleanup here.
When we are deciding whether to preserve scroll position, we
mainly care that then_select_offset is set to a value. If
we had no intention of preserving scroll offset, we would have
never bothered to set it. The check for !select_first_unread
is always redundant, as verified by lots of clicking around
with some print debugging. And it's a brittle check,
because it couples the decision of scrolling destination to
the mechanism by which we decide our selection. While those
things are closely related, it's possible in the future that
we'll decide to advance to an unread message and still want
to set then_select_offset, but we might forget to mutate
select_first_unread.
Long story short, the code is simpler and safer now.
We move the var declaration of then_select_offset closer to
where it gets calculated, and we avoid code duplication in
calling current_msg_list.get_row().
Even when then_select_id has the sentinel value of -1, we were
trying to look it up in our message_list.all object. This would
have returned undefined, which is fine, but it's more explicit
to just bypass the check.
This mostly sets up the next commit. The two conditions here
are both inexpensive to check, but we want to bypass an upcoming
expensive operation if can_apply_locally() returns false.
With past logic, on fast upload progress bar don't appears because
uploadFinished is called as soon as upload is finished so
progress bar get disappeared. To make these hiding of progress bar
smooth we set setTimeout for every hiding of progress bar as well
as complete status element.
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.
Previous logic was little buggy, as many time there can be considerable
difference between uploadFinished and progressUpdated as progressUpdated
can finish much earlier(on a slow connection) and the "uploaded file"
markdown text is inserted with some delay.
It is also a preliminary commit for making each progress bar independent
as currently progressUpdated may close upload_bar even after only
one file out of many files is uploaded.
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.
Currently when admin add/remove/update custom fields, changes
are not reflected in user settings page, if settings tab
is already open. This might be rare case, but it looks like
an error when admin go to user settings page just after
updating custom fields in org settings.
Fix this by re-rendering custom fields in user settings
on custom_profile_fields event.
In a refactor last fall, we changed `set_message_booleans` to mutate
state (specifically, destroying msg.flags in favor of setting
properties like `msg.unread`). This was fine for most code paths, but
the maybe_add_narrowed_messages code path called
`message_store.add_message_metadata` twice (once after talking to the
server to find out whether the messages go into the current narrow),
and so when we extracted set_message_booleans from that, the second
call didn't properly short-circuit.
We fix this by just removing the second call, and also add a comment
warning about the add_message_metadata call there as being dangerous.
Fixes#8184.
