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.)
