This commit extract send_messages.js to clean up code related
to the following things:
* sending data to /json/report_send_time
* restarting the event loop if events don't arrive on time
The code related to /json/report changes the following ways:
* We track the state almost completely in the new
send_messages.js module, with other modules just
making one-line calls.
* We no longer send "displayed" times to the servers, since
we were kind of lying about them anyway.
* We now explicitly track the state of each single sent
message in its own object.
* We now look up data related to the messages by local_id,
instead of message_id. The problem with message_id was
that is was mutable. Now we use local_id, and we extend
the local_id concept to messages that don't get rendered
client side. We no longer need to react to the
'message_id_changed' event to change our hash key.
* The code used to live in many places:
* various big chunks were scattered among compose.js,
and those were all moved or reduced to one-line
calls into the new module
* echo.js continues to make basically one-line calls,
but it no longer calls compose.report_as_received(),
nor does it set the "start" time.
* message_util.js used to report received events, but
only when they finally got drawn in the home view;
this code is gone now
The code related to restarting the event loop if events don't arrive
changes as follows:
* The timer now gets set up from within
send_messages.message_state.report_server_ack,
where we can easily inspect the current state of the
possibly-still-in-flight message.
* The code to confirm that an event was received happens now
in server_events.js, rather than later, so that we don't
falsely blame the event loop for a downstream bug. (Plus
it's easier to just do it one place.)
This change removes a fair amount of code from our node tests. Some
of the removal is good stuff related to us completing killing off
unnecessary code. Other removals are more expediency-driven, and
we should make another sweep at ramping up our coverage on compose.js,
with possibly a little more mocking of the new `send_messages` code
layer, since it's now abstracted better.
There is also some minor cleanup to echo.resend_message() in this
commit.
See #5968 for a detailed breakdown of the changes.
Because of local echo, message ids can change in message rows.
Having reactions use markup to indicate their message id just
creates more moving parts, since we would need to handle
message_id_changed events.
Now our handlers just call row.get_message_id() as needed.
We no longer do the message_store piece of reifying ids
via a trigger. We now make an explicit call to an
ordinary function.
This has several benefits:
- no more initialize() function
- no more scary comments about garbage collection
- the function has a real name now
- the function is less indented
- we can easily see when the message_store step happens
- simpler node tests
- simpler tracebacks (no jQuery cruft)
I pushed a bunch of commits that attempted to introduce
the concept of `client_message_id` into our server, as
part of cleaning up our codepaths related to messages you
sent (both for the locally echoed case and for the host
case).
When we deployed this, we had some strange failures involving
double-echoed messages and issues advancing the pointer that appeared
related to #5779. We didn't get to the bottom of exactly why the PR
caused havoc, but I decided there was a cleaner approach, anyway.
This is mostly straightforward moving of code out of compose.js.
The code that was moved currently supports sending time
reports for sent messages, but we intend to grow out the new
module to track more state about sent messages.
The following function names in this commit are new, but their
code was basically pulled over verbatim:
process_success (was process_send_time)
set_timer_for_restarting_event_loop
clear
initialize
All the code in the new module is covered by previous tests that
had been written for compose.js. This commit only modifies
a few things to keep those tests.
The new module has 100% node coverage, so we updated `enforce_fully_covered`.
This old third party library added support
for a "mousewheel" event to detect scrolling.
However, it is not compatible with jQuery 3
and is obsolete now that there is a standard
"wheel" event that accomplishes the same thing.
The function modals.is_active() can see if modals are open
without having to look at the DOM. This should make it snappier
to type in the compose box. Even if the speedup is pretty minor,
not having to worry about jQuery slowness should make it easier
to diagnose future compose box issues.
The new function gets used in other places, too, where performance
isn't so much an issue.
This removes the old compose emoji picker in its entirety, changing
the few callbacks needed to launch the reactions-style emoji picker
instead and hook it up properly.
Callbacks for reactions and composing messages are distinguished by
selecting for, respectively, the .reaction and .composition classes.
Fixes#4122.
Fixes bugs of when multiple messages are being edited simultaneously.
Specifically, typeahead is no longer broken, copying messages to clipboard
is less buggy, and resizing is no longer
broken when multiple messages are being edited.
This module extracts these two functions that get called by
several other modules:
start()
cancel()
It is a little bit arbitrary which functions got pulled over
with them, but it's generally functions that would have only
been called via start/cancel.
There are two goals for splitting out this code. The first
goal is simply to make `compose.js` have fewer responsibilities.
The second goal is to help break up circular dependencies.
The extraction of this module does more to clarify
dependencies than actually break them. The methods start()
and cancel() had actually been shimmed in an earlier commit,
and now they no longer have a shim.
Besides start/cancel, most of the functions here are only
exported to facilitate test stubbing. An exception is
decorate_stream_bar(), which is currently called from
ui_init.js. We probably should move the "blur" handler out
of there, but cleaning up ui_init.js is a project for another
day.
It may seem slightly odd that this commit doesn't pull over
finish() into this module, but finish() would bring in the
whole send-message codepath. You can think of it like this:
* compose_actions basically just populates the compose box
* compose.finish() makes the compose box do its real job,
which is to send a message
For the settings UI, we now wait until a user goes to a particular
settings section before calling the appropriate function to set
up the section (which usually involves setting up click handlers
and populating initial data).
This commit adds the backend support for a new style of tutorial which
allows for highlighting of multiple areas of the page with hotspots that
disappear when clicked by the user.
