Anders Kaseorg d72423ef21 eslint: Replace empty-returns with consistent-return.
Instead of prohibiting ‘return undefined’ (#8669), we require that a
function must return an explicit value always or never.  This prevents
you from forgetting to return a value in some cases.  It will also be
important for TypeScript, which distinguishes between undefined and
void.

Mohit Gupta 4167517a6f filters: Fix has:image and avoid future issues for other has filters.
This fixes a bug with the original frontend-side implementation for
has: filters, where it would incorrectly not match content in cases
where the message's nesting structure did not have an outer tag.

Bug was introduced in 02ea52fc18.

Fixes #16118.

Aman Agrawal 1b05f8e6c9 stream_topic_history: Update max msg id of stream post msg deletion.
After the latest message in a stream is deleted, we should update
the max_message_id in the stream.

Removed false comment in message_util.get_messages_in_topic
this method only takes 2ms for 10,000 messages loaded locally.

Mohit Gupta 02ea52fc18 filter: Implement has: filters on client side.
Prior to this commit has:link, has:attachment, has:image
filter couldn't be applied locally and deferred filtering to
web server. This commits make sure client filters all messages
it can instead of completely deferring to the server and hence
improve speed.

A tradeoff is also made to turn off local echo for has: narrows
as messages with link sent to has:link narrow were locally echoing
to another narrow and not appearing in the active has:link narrow.

Fixes: #6186.

Ryan Rehman 6637f2dbb7 message list: Render new messages only after "newest" is found.
If a user sends a message while the latest batch of
messages are being fetched, the new message recieved
from `server_events` gets displayed temporarily out of
order (just after the the current batch of messages)
for the current narrow.

We could just discard the new message events if we havent
recieved the last message i.e. when `found_newest` = False,
since we would recieve them on furthur fetching of that
narrow.
But this would create another bug where the new messages
sent while fetching the last batch of messages would not
get rendered. Because, `found_newest` = True and we would
no longer fetch messages for that narrow, thus the new
messages would not get fetched and are also discarded from
the events codepath.

Thus to resolve both these bugs we use the following approach:

* We do not add the new batch of messages for the current narrow
  while `has_found_newest` = False.
* We store the latest message id which should be displayed at the
  bottom of the narrow in `fetch_status`.
* Ideally `expected_max_message_id`'s value should be equal to the
  last item's id in `MessageListData`.
* So the messages received while `has_found_newest` = False,
  will be fetched later and also the `expected_max_message_id`
  value gets updated.
* And after fetching the last batch where `has_found_newest` = True,
  we would again fetch messages if the `expected_max_message_id` is
  greater than the last message's id found on fetching by refusing to
  update the server provided `has_found_newest` = True in `fetch_status`.

Another benefit of not discarding the events is that the
message gets processed not rendered i.e. we still get desktop
notifications and unread count updates.

Aman Agrawal 5443b2f635 recent_senders: Update data structures for stream/topic edits.
* Remove old topic and reprocess both old and new topic to ensure
that we are correctly storing the last_msg_id of users in the
topic. Also, Handle topic's stream (& topic) edit updates.
* Add function to get all messages in a topic in message_utils.js.
* Send topic edit event to recent_senders.
* Add func get sorted list of recent_senders to topic.
The function will be useful to handle topic edits in Recent Topic UI.

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.

Steve Howell b3594c984a message scrolling: Fix "Scroll down to view" warning.
We recently added a feature to warn users that they
may need to scroll down to view messages that they
just sent, but it was broken due to various complexities
in the rendering code path.

Now we compute it a bit more rigorously.

It requires us to pass some info about rendering up
and down the stack, which is why it's kind of a long
commit, but the bulk of the logic is in these JS files:

    * message_list_view.js
    * notifications.js

I choose to pass structs around instead of booleans,
because I anticipate we may eventually add more metadata
about rendering to it, plus bools are just kinda brittle.
(The exceptions are that `_maybe_autoscroll`, which
is at the bottom of the stack, just passes back a simple
boolean, and `notify_local_mixes`, also at the bottom
of the stack, just accepts a simple boolean.)

This errs on the side of warning the user, even if the
new message is partially visible.

Steve Howell 6f8da1bb27 Refactor: Split up add_messages api.
We now have two functions:

    add_new_messages
    add_old_messages

This is a lot easier on the eyes, and it will also
prevent us from exceeding line length in future commits.

We also remove an unneeded stub in the narrow_activate
tests.

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.

Steve Howell 3f06f28ad7 sending messages: Extract sent_messages.js.
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.

Steve Howell 475eb21a5e Revert commits related to client_message_id.
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.

Steve Howell 9ee2be4a0d Use client_message_id as key for sent_messages lookups.
We now use a client-side message id to track the state of our
sent messages.  This sets up future commits to start tracking
state earlier in the message's life cycle.

It also avoids ugly reify logic where we capture an event to
update our data structure to key on the server's message id
instead of the local id.  That eliminates the node test as well.

Another node test gets deleted here, just because it's not
worth the trouble with upcoming refactorings.

Steve Howell f6d670ae3d Extract sent_messages.js.
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`.
