This commit adds call_function_periodically helper function
which will be used to call functions periodically using
setTimeout. Currently, this new function is used to send
presence requests and trying reload.
Instead of using setInterval to call send_presence_to_server
repeatedly, we now simluate setInterval using setTimeout.
This change helps us to avoid the condition likely related to resume
from suspend, when the browser tries to catch up by running a large
number of "missed" copies of the setInterval hook, causing the server
to rate-limit the client.
Fixes#23438.
Transitions the frontend of the web app to no longer use the
user status `away` field for setting a user's activity status
to be 'unavailable' (which is now a deprecated way to access
a user's `presence_enabled` setting).
Instead we now directly use and update the user's `presence_enabled`
setting for this feature.
Renames frontend code related to the feature to `invisible_mode`
vs `away`.
We lose node test coverage in `user_status.js` because we are now
using `channel.patch` to send these user setting updates to the
server.
Removes the temporary updates to `server_events_dispatch.py` (and
related tests) made in a previous commit, since we no longer have
or need the `away_user_ids` set.
This was added by commit 7f174213ed, and
appears to have been designed for responses that are *successful* but
falsy. Logically, these should not implicitly represent a failure to
be retried if it were.
Note from tabbott: The background is that this idempotent retry loop
was a hacky workaround for a bug we never understood but saw daily in
production. Especially during server restarts / client reloads,
something would result in 200 responses with no data being seen by the
frontend, despite the Django server not having received/processed the
request. Fortunately, this strange failure mode appears to have
stopped happening in late 2019, so we can delete this hack.

The Event.which and Event.keyCode are deprecated as pointed out by
TypeScript intellisense based on the jQuery types. We use Event.key
instead which behaves similarly to Event.which & Event.keyCode for
our use case.
The only difference in functionality by this change is that the vim
keys won't work when Caps Lock is on. This is because, in this case,
the key property will be "J" instead of 'j'. We can fix this by
adding a mapping for this, however, I think we don't want to handle
this case so I left this change out. Tested by trying out the
everywhere keydown_util is used.
Finally, we also turn off the new-cap rule for tests since I think
it fine to only enforce it on real code and exempting test code is
fine.
While rest of the app has ported to the new system of updating
unread_counts `activity` was not ported. This resulted in
unread count in buddy list not being updated when new
PMs arrive.
Now when we want to measure how long a block
of code takes to execute, we just wrap it with
`blueslip.measure_time`, instead of the awkward
idiom from my original commit of getting a callback
function.
My rationale for the original scheme was that I
wanted to minimize diffs and avoid changing
`const` to `let` in a few cases, but I believe
now that the function wrapper is nicer.
In a few cases I just removed the blueslip timing
code, since I was able to confirm on czo that
the times were pretty minimal.
Using web_public_guest for anonymous users is confusing since
'guest' is actually a logged-in user compared to
web_public_guest which is not logged-in and has only
read access to messages. So, we rename it to
web_public_visitor.
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.

ES and TypeScript modules are strict by default and don’t need this
directive. ESLint will remind us to add it to new CommonJS files and
remove it from ES and TypeScript modules.

We remove the "GROUP PMs" section that used
to be in the lower right sidebar.
Most of this is straightforward code removal.
A couple quick notes:
- The message fetching code now just
calls `huddle_data.process_loaded_messages`,
which we still need for search suggestions.
We removed `activity.process_loaded_messages`.
- The `huddle_data.process_loaded_messages`
function no longer needs to return `need_resize`.
- In `resize.js` we now just calculate
`res.buddy_list_wrapper_max_height` directly
from `usable_height`.
This makes it so that search_suggestion.js
does not depend on activity.js.
That dependency hasn't really been "elegant"
for quite some time, but it will become particularly
unnecessary when we go to remove the "Group PMs"
section from the right sidebar.
This commit introduces a temporary wart
where we have these two functions with the
same name in a sort of unnecessarily
complicated code stack:
activity.process_loaded_messages
huddle_data.process_loaded_messages
But we will eliminate the former function
very soon, and our message-related codepaths
will just call the `huddle_data` version
directly.
TESTING NOTES:
Now that `huddle_data` is a tiny leaf
module, it's super easy to just use the
real implementation of what was formerly
called `activity.get_huddles()` (and is
now in `huddle_data`).
When I first wrote this commit, introducing
the real implementation of `get_huddles` exposed
some bugs that I fixed in the immediately
prior commits to this.
When the tests were originally written,
I believe `activity.js` had some annoying
`jQuery` dependencies that made it hard
to unit test against. We've slimmed it over
time to be mostly just a "controller" module.
But even in its current state it would have
been a bit of a bloated dependency.
The other friction for using the actual
version of `get_huddles` was setting up
the message data, but that's pretty minor.
This exists in all versions of the desktop app that we still support,
and will eventually let us delete a bit of annoying compatibility code
from the desktop app’s injected JavaScript.

This generalizes existing code for the presence code path that is
generically useful for avoiding useless work that will be discarded.
We make an exception for the one type of request that needs to happen
while reloading, namely the one to clean up our event queue.
We used to have a block of code doing this just in the presence
endpoint because that's where we'd had error-handling problems with it
not being present, but it seems more correct for it to run
unconditionally on all HTTP requests.
This requires adding a dependency of channel on reload_state, which we
record in the webpack configuration for now.
