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.
The actual goal we have is that suspect_offline is correct so that we
can rely on that field when determining how to do error handling in
the presence system.
This avoids risk of logging blueslip errors for user IDs seen in the
presence response that we haven't heard about from the server_events
system because we're offline and in the process of reloading.
The issue only affected large realms; see
02bc630881 and `git log
-Ssuspect_offline` for details.
In the next commit we're going to change what the
server sends for the following:
- page_params
- server responses to /json/users/me/presence
We will **not** yet be changing the format of the data
that we get in events when users update their presence.
It's also just a bit in flux what our final formats
will be for various presence payloads, and different
optimizations may lead us to use different data
structures in different payloads.
So for now we decouple these two things:
raw_info: this is intended to represent a
snapshot of the latest data from the
server, including some data like
timestamps that are only used
in downstream calculations and not
user-facing
exports.presence_info: this is calculated
info for modules like buddy_data that
just need to know active vs. idle and
last_active_date
Another change that happens here is we rename
set_info_for_user to update_info_for_event,
which just makes it clear that the function
expects data in the "event" format (as opposed
to the format for page_params or server
responses).
As of now keeping the intermediate raw_info data
around feels slightly awkward, because we just
immediately calculate presence_info for any kind
of update. This may be sorta surprising if you
just skim the code and see the various timeout
constants. You would think we might be automatically
expiring "active" statuses in the client due to
the simple passage of time, but in fact the precise
places we do this are all triggered by new data
from the server and we re-calculate statuses
immediately.
(There are indirect ways that clients
have timing logic, since they ask the
server for new data at various intervals, but a
smarter client could simply expire users on its
own, or at least with a more efficient transfer
of info between it and the server. One of
the thing that complicates client-side logic
is that server and client clocks may be out
of sync. Also, it's not inherently super expensive
to get updates from the server.)
Babel strict generates more code for [...x] than you’d like, while
Babel loose mode assumes x is an array.

This flag affects page_params and the
payload you get back from POSTs to this
url:
users/me/presence
The flag does not yet affect the
presence events that get sent to a
client.
This is relatively unobtrusive, and we don't send
anything to the server.
But any user can now enter blueslip.timings in the
console to see a map of how long things take in
milliseconds. We only record one timing per
event label (i.e. the most recent).
It's pretty easy to test this by just clicking
around. For 300 users/streams most things are
fast except for:
- initialize_everything
- manage streams (render_subscriptions)
Both do lots of nontrivial work, although
"manage streams" is a bit surprising, since
we're only measuring how long to build the
HTML from the templates (whereas the real
time is probably browser rendering costs).
This required lots of manual testing:
- search/navigate user presence
- send PM and mention user
- pay attention to compose fade
- send stream msg and mention user
- open Private Messages in top-left and click
- test unread counts
- invite user who already has account
- search for users in search bar
- check user settings
- User Groups
- Users
- Deactivated Users
- Bots
- create a bot
- mention user groups
- send group PM then click on lower right
- view/edit/create streams
If there are still pieces of code that don't convert
ids to ints, the code should still work but report
blueslip errors.
I try to mostly convert user_ids to ints in the callers,
since often the callers are dealing with small amounts
of data, like user ids from huddles.
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.

With webpack, variables declared in each file are already file-local
(Global variables need to be explicitly exported), so these IIFEs are

The count_span element is parented by a .selectable_sidebar_block element
which is parented by the li element that the class is supposed to be added
to. Thus, use the parents() jQuery method for locating the li parent so
that the class gets added to the correct element.
Combined with work in the desktop app, this makes it possible for the
desktop app to clearly indicate to other users whether the current
user is active on the system and thus would see a desktop
notification, not just whether they are active in the current Zulip
window.
Essentially rewritten by tabbott to add unit tests and consider the
desktop app data authoritative.
These names were incorrect, as they made it sound like this feature
was about the browser window being focused, whereas they are in fact
about whether the user has accessed the browser window.
With perfectScrollbar, we needed to call a function from JavaScript to
enable a scrollbar on a new element, but simplebar has a much simpler
default API one can do by using data-simplebar attributes in the HTML.
So we can delete all the scrollbar creation/deletion code.

perfect-scrollbar replaces both the appearance and the behavior of the

This is mostly adding markup, calling some convenient
functions in buddy_data.js, and adjusting CSS.
To make the circles update dynamically, I mostly
orchestrate this though activity.js for now. It's
possible we'll want to adjust that eventually to
happen through something like a `presence_events`
dispatcher, but that's essentially what
a good part of `activity.js` does now.
In small screen sizes, when the user presses shortcut `w` to search
for another user, the hide_all function calls in the search code path
would hide the right sidebar, immediately after opening it, making the
hotkey basically unusable.
We fix this by extracting a separate hide method that hides all true
popovers, but not the user list sidebar.
Fixes#11463.
The name `insert_user_into_list` is sort of misleading,
since we are often just redrawing the user's existing
item in the buddy list.
I chose `redraw_user` over `update_user` to emphasize
that we're just going to redraw it with whatever data
has been updated by the callers.
We are trying to carve room for a more specific
"user_status" concept, which refers to statuses
that users specifically set, like "I'm away".
So we call this function "update_presence_info",
which reflects that it's more about actual
"presence"--i.e. the user really is present
in the browser, even though the actual human
may not want to be disturbed.
For many years we have been excluding the current user
from the buddy list, since their presence is kind
of implicit, and it saves a line of real estate.
This commit removes various user-is-me checks
and puts the user back for the following reasons:
* explicit is better
* newbies will be less confused when they
can see they're actually online
* even long-time users like myself will
feel more comfortable if it's just there
* having yourself in the buddy list facilitates
things like checking your presence or sending
yourself a message
* showing "me" reinforces the meaning of the
green circle (if my circle is green and I'm
active, then others with green circles must
be active too)
* If you're literally the first user in the
realm, you can now see what the buddy list
looks like and try out the chevron menu.
The biggest tradeoff here is the opportunity cost.
For an org with more people than fit on the screen,
we put the Nth person below the fold to show "me".
I think that's fine--users can still scroll or
search.
This commit doesn't do anything special with the
current user in terms of sorting them higher in the
list or giving specific styling.
Fixes#10476
This is part of work to break some of our
nastier circular dependencies in preparation
for our es6 migration.
This commit should facilitate loading leaf-like
modules such as people.js before all of the things
that reload.js depends on.
This new div allows us to split out two concerns:
semantic list of items - remains in #user_presences
widget real estate - controlled by new #buddy_list_wrapper
We will use this for progressive rendering. We want to add
padding to the buddy list without messing with the integrity
of the actual HTML '<ul>' list. (One ugly alternative would
have been to add a dummy list item, which be a pitfall for
any code traversing the list.)
Basically, all the code relating to click handlers and similar
things was left alone. We only change js/css related to
scrolling, resizing, and overflow.
This version of progressive scrolling lazily
renders buddy list items, but it doesn't
provide the browser with any notion of upcoming
list items, so as you scroll down and the size
of the rendered list grows, the scrollbar shows
you being too close to the bottom.
This maintains 100% coverage on buddy_list.js.
We were passing this in before, but having it as
a data member reinforces the idea that we'll want
this to be a first-class concept in the list, since
we depend on ordering for various things.
We now keep track of keys in buddy_list.js, so that
when we insert/remove items, we no longer need to
traverse all the DOM. Instead, we just find out
which position in the list we need to insert the
key in (where "key" is "user_id") and then find
the relevant DOM node directly and insert the new
HTML before that node. (And of course we still
account for the "append" case.)
There's a little more bookkeeping to make this
happen, but it should help reduce some code in
upcoming commits and pave the way toward
progressive rendering optimizations.
This commit should produce a minor speedup
for activity-related events that go through
buddy_list.insert_or_move(), since we are
not traversing the DOM to find insertion points
any more.
