In 47aaa73f96, we fixed one issue, which
is that server_events_dispatch.js was calling `update_starred` with
the wrong arguments, but created a new one (toggle_starred wasn't
updated) and missed another (which is that we weren't ever updating
message.starred, and thus if you toggle a message's star-state in one
browser, and then tried to toggle it back in a second, it would feel
like the click didn't work, because it was trying to toggle
e.g. off->on a second time).
This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
Fixes#8965.
Mark_message(s)_as_read is used in marking a message as having been
read by the browser, rename it to notify_server_message(s)_read to
avoid any confusion.
We were queuing up individual messages to be flagged as
read on the server before this change, and we used debounce
to avoid sending individual POSTs, but this created delays
that were ripe for race conditions.
Now we batch them in the caller and use throttle instead.
This now prevents us from slamming the server with lots of
individual requests, without as many opportunities for races.
(Note that we still have some possibility of race conditions,
but they should be rare now, and other commits will address
some of the other contributors to read/unread glitches.)
In the JS code, we now use `message.unread` universally as
the indicator of whether a message is unread, rather than
the `message.flags` array that gets passed down to us
from the server.
In particular, we use the unread flag for filtering when
you search.
A lot of this commit is just removing logic to add/remove
"read" from `message.flags` and updating tests.
We also explicitly set `message.unread` to `false` inside of
`unread.mark_as_read()` and no longer have `unread.set_flag()`.
(Some of the callers to `unread.set_flag` were also calling
`unread.mark_as_read`, which was updating the `message`
object, so now we just have `unread.mark_as_read` update
the `message` object. And then unread_ops.mark_all_as_read()
was already calling unread.declare_bankruptcy().)
We now make direct calls to `send_flags_update` for
seting collapsed/uncollapsed, rather than going through
the `batched_updaters` mechanism.
Also the methods in `message_flags` to set
collapsed/uncollapsed now take a single message.
We now do all of the main logic for starring/unstarring
a message in `message_flags.toggle_starred`:
* mark the message as read (just in case)
* update the UI (i.e. the green star in the message)
* update the server
The calling code in both the click handler and the hotkey
handler remains simple--they just handle minor details like
finding the message and clearing popovers.
For updating the server, we now call the new
`send_flag_update` helper.
And we continue to delegate some of the logic to
`ui.update_starred`, but we remove some code there that's
now pushed up to `message_flags.toggle_starred`.
This change should be mostly transparent to users, but it
does remove some inconsistent behaviors between the click
handler and the hotkey handler. Before this change, the
click handler was more aggressive about updating the UI
and marking the message as read. For people using the "*"
key to star/unstar, they probably would only have noticed
different behavior on a slow connection or in an edge
case scenario where only half of the message was onscreen.
More importantly, by simplifying how we talk to the server,
this eliminated up to a one-second lag due to the debounce
logic in the batch_updater code. The complicated debounce
logic is only really needed for batch-updating "read"
messages, and it was overkill and sluggish for starring
messages.
Last but not least, we add defensive code for the local
echo case. (Users have to wait till the message gets acked
to star it.)
This experiment has been disabled for everyone for a while: if we
bring something like this back, it is not likely to be exactly the same,
and will be different enough to require a different implementation.
As it is, the summarization code was making a few code paths (rendering
especially) more complex, and is worth removing for simplicity's sake.
