Anders Kaseorg 28f3dfa284 js: Automatically convert var to let and const in most files.
This commit was originally automatically generated using `tools/lint
--only=eslint --fix`.  It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

ruchit2801 9f7e90f68b left sidebar: Add an "unstar all messages" option.
In this commit, I've added a feature to unstar all the starred
messages.  This is useful, e.g., for folks who are using starred
messages to keep track of things they should come back when next at
their desktop.

The event flow is the standard one for a feature with a confirmation modal:

(1) User clicks on unstar all messages.

(2) We display a confirmation modal; if the user confirms, we send a
request to the backend to clear all starred messages.

(3) The events system sends that UI update back to us, removing the
stars from the UI.

Fixes #11401.

Tim Abbott 0044866682 events: Fix starring logic correctly.
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).

Armaan Ahluwalia 6d255efe4c app: Prepare JS files for consumption by webpack.
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.

read by the browser, rename it to notify_server_message(s)_read to
avoid any confusion.

Steve Howell 58ec5f9695 Use throttle, not debounce, to "read" messages.
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.)
2017-12-26 09:01:21 -05:00
Steve Howell 199650d5c7 refactor: Stop using flags array for unread counts.
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().)

Steve Howell 7a362861d0 frontend: Simplify saving collapsed/uncollapsed flags.
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.
2017-12-26 09:01:21 -05:00
Steve Howell d52552dcc3 Simplify/unify starring messages from the frontend.
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.)

Steve Howell 0e25055c1d Add explicit message field for locally_echoed.
We now set locally_echoed to true for messages that are

Leo Franchi 748e5b6da6 Remove disabled summarization code
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.
