We now have a function get_user_circle_class
that returns one of these values:
"user_circle_green"
"user_circle_orange"
"user_circle_empty"
And we put that in the templates.
And then CSS renders the circle of the appropriate
color.
The unit tests now explicitly capture whether
we are rendering the correct kind of circle.
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.
We add a padded div to our container for the buddy
list to give scrolling the illusion that we've
rendered every list item, while still letting
the browser do the heavy lifting instead of trying
to fake it out too much.
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 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.
This is preparation for our migration of our JS pipeline to webpack,
which includes as part of the process a hack of exporting globals via
the window object.
This run_test helper sets up a convention that allows
us to give really short tracebacks for errors, and
eventually we can have more control over running
individual tests. (The latter goal has some
complications, since we often intentionally leak
setup in tests.)
When we populate the buddy list or update it for activity, we now
have buddy_data set a faded flag that is rendered in the template.
This avoids some re-rendering overhead and is on the eventual path
to having our widget be more data-oriented (and all rendering happens
"behind" the widget).
We still do direct DOM updates when the compose state changes or
when we get peer subscription events.
This introduces a generic class called list_cursor to handle the
main details of navigating the buddy list and wires it into
activity.js. It replaces some fairly complicated code that
was coupled to stream_list and used lots of jQuery.
The new code interacts with the buddy_list API instead of jQuery
directly. It also persists the key across redraws, so we don't
lose our place when a focus ping happens or we type more characters.
Note that we no longer cycle to the top when we hit the bottom, or
vice versa. Cycling can be kind of an anti-feature when you want to
just lay on the arrow keys until they hit the end.
The changes to stream_list.js here do not affect the left sidebar;
they only remove code that was used for the right sidebar.
In this cleanup I make it so that all jQuery selector references
are toward the top of the module, and we do all finds relative
to the container ('#user_presences').
This will make it easier to make a better list abstraction for
the buddy list, for things like progressive rendering.
This was a bit more than moving code. I extracted the
following things:
$widget (and three helper methods)
$input
text()
empty()
expand_column
close_widget
activity.clear_highlight
There was a minor bug before this commit, where we were inconsistent
about trimming spaces. The introduction of text() and empty() should
prevent bugs where users type the space bar into search.
This does a few things:
* removes some unnecessary setup
* puts some jQuery setup closer to where it's needed
* renames some variables
* adds an assertion about highlighting
We never make an actionable distinction between the "unknown"
presence status and the "offline" status, so we now
just use "offline" as the status for persons who don't
have recent presence records that the client knows about.
(Usually, users without presence rows have never been online,
or they have been deactivated, or they have been offline so long
that they don't show up in our date-limited queries.)
We sometimes get blueslip errors from browsers that are clearly still
attempting to reload long after they should have. These browsers can
produce a lot of unnecessary presence update exceptions.
To solve that, we start checking reload_in_progress in the presence
code path.
While we're at it, we also add some blueslip logging for the reload
code path, in case it becomes useful when debugging future issues.
This function was extracted from build_user_sidebar(). We
also slightly streamlined it to not unnecessarily call
filter() when the filter text was blank. This extraction
also eliminated the need for us to have the two-line
filter_and_sort() function.
Also, we get to 100% coverage in this commit.
We now intialize user-list-filter within activity.initialize(),
which gives us more control to set the module variable
`meta.$user_list_filter` before we build the user sidebar,
while setting up its handlers after we build the sidebar.
This adds the perfectScrollbar to the right side and theoretically
updates it any time a piece of code interacts with the sidebar and
updates the counts of users displayed in it.
This function no longer sets properties to false, so the supported
way of doing this is to instead use prop(foo, false). Some tests
had to be fixed to accommodate this.
This commit add $.create(), which allows you to create a
jQuery object that just has a name to identify it, as opposed
to some selector or HTML fragment. It's useful for things that
are really used as stubs.
This also fixes a bunch of the existing tests to use $.create().
Before this fix, you could actually just do $('some-stub'), but
now we enforce that the input to $() looks like a valid selector
or HTML fragment, and we make some exceptions for things like
window-stub and document-stub.
Hopefully this will make it more explicit that zjquery does
not truly simulate DOM, but it instead allows you to dynamically
set what you want the results of $('foo').find(some_selector)
to be.
Before this commit, we were erroneously setting up parents
as part of add_child() calls, but it's not necessarily the
case that those children are immediate children, and therefore
the first object is not necessarily the immediate parent.
For bots and users who have not logged in for a long time the presence information is not known. For the these users make the presence indicator hidden.
For small-ish realms (<= 250 users), we ensure that the presence
info includes all realm users the front end knows about, even in
cases where the server sends down a slimmed version of presence
data. We make the users "offline" by default, of course.
This commit sets us up to optimize larger realms without concerns
of breaking small realms. Small realms may want to continue to
show all users, even users who may have been offline several weeks,
since it doesn't clutter their API as much as it would for big
realms.
Most of this code was simply moved from activity.js with some
minor renaming of functions like set_presence_info -> set_info.
Some functions were slightly nontrivial extractions:
is_not_offline:
came from activity.huddle_fraction_present
get_status/get_mobile:
simple getters
set_user_status:
partial extraction from activity.set_user_status
last_active_date:
pulled out of admin.js code
We also fixed activity.filter_and_sort to take user_ids.
It's easier to reason about the activity.js code if we just
make it clear that presence_info is a global singleton. Going
forward, functions that use that data will explicitly refer to
exports.presence_info.
This change makes some tests slightly more awkward to set up, but
with the actual code you now don't have to question whether there
are multiple copies of presence_info to maintain.
The diff for compare_function is a bit confusing to read, but it's
basically just de-dented since we don't need to parameterize the
compare function any more.
Activity.update_users() is still used to handle partial
updates of users in the buddy list, but now all the places
that want to re-build the whole widget go through
build_user_sidebar().
The slugs for PM-with narrows now have user ids in them, so they
are more resilient to email changes, and they have less escaping
characters and are generally prettier.
Examples:
narrow/pm-with/3-cordelia
narrow/pm-with/3,5-group
The part of the URL that is actionable is the comma-delimited
list of one or more userids.
When we decode the slugs, we only use the part before the dash; the
stuff after the dash is just for humans. If we don't see a number
before the dash, we fall back to the old decoding (which should only
matter during a transition period where folks may have old links).
For group PMS, we always say "group" after the dash. For single PMs,
we use the person's email userid, since it's usually fairly concise
and not noisy for a URL. We may tinker with this later.
Basically, the heart of this change is these two new methods:
people.emails_to_slug
people.slug_to_emails
And then we unify the encode codepath as follows:
narrow.pm_with_uri ->
hashchange.operators_to_hash ->
hashchange.encode_operand ->
people.emails_to_slug
The decode path didn't really require much modication in this commit,
other than to have hashchange.decode_operand call people.slug_to_emails
for the pm-with case.
Merged two tests since they both use the same test data. The file name
of `presence_list_performance.js` also causes confusion as it is no longer
use for performance testing.
* In most cases, eslint --fix with the right comma-dangle settings was
able to update the code correctly.
* The exceptions were cases where the parser incorrectly treated the
arguments to functions like `assert_equal` as arguments; we fixed
these manually. Since this is test code, we can be reasonably
confident that just fixing the failures suffices to correct any bugs
introduced by making changes automatically.
When we filtered buddy lists, a recent change introduced some
bugs related to case-insensitive emails. We now circumvent the
bug by indexing presence_info with user_ids.
It used to be the case that you would get new messages for a
huddle, but the huddle wouldn't show up on your buddy list until
the every-50-seconds mass update of the buddy list.
Now we make sure to work with non-stale jQuery objects, and,
more importantly, we resize ourselves if we add new huddles.
(The resize issue arises due to some complicated heuristics
where we don't want group PMs to take up too much of the buddy
list for users who don't have many in their history.)
