Introducing the level function makes it a bit more clear that active
users get sorted to the top.
It also shaves a couple milliseconds for large buddy lists, although
that is mostly negligible compared to name sorting and rendering.
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.
The function focus_lost() was setting has_focus to false
in all cases; now it does it more clearly. I also added a
comment explaining why we don't ping on losing focus.
We no longer build the buddy list twice during page load; we
build it just once from page_params information. (We also send
the initial ping and schedule subsequent pings slightly later in
the process.)
We also don't do redraws upon regaining focus, since we don't
show ourselves in the buddy list, and even if we did, we wouldn't
need a full server update.
To have this flexibility, we introduce the want_redraw flag to
focus_ping.
A clear-search option to clear the user-list searchbox has been added.
This feature was present in the main searchbar but absent elsewhere.
Fix a part of #3716.
We now call activity.build_user_sidebar when we initialize
the user sidebar, which avoids some janky jQuery code
that was intended for partial updates.
With 2000 users in dev, the amount of time to build the sidebar
decreases from 1100ms to 700ms in my tests. (Times vary a bit,
but it does seem consistently faster now.)
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 function people.filter_by_search_terms() used
to return a JS object with emails as keys to represent
a set of users. Now we return a Zulip Dict() object
with user_ids as keys.
For the "GROUP PMs" part of the right sidebar, we now have
accurate hrefs when you hover over the groups or right-click
to copy links or open links in new tabs.
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.
When somebody changes their name, we will now update
the buddy list right away. The old code was trying
to do this through a code path that was designed for
true presence updates, but it was also passing in an
empty array, instead of undefined, which caused it to
fail to invoke the intended part of the codepath to
redraw the buddy list.
Now we just call the new activity.redraw() function,
which does the right thing for the buddy list.
The group PM list was live-updating before this change,
and it continues to live-update as part of the new
activity.redraw() function.
We now sort users by the lower case value of their
full names in each of the links in the "GROUP PMs"
section of the right sidebar. We still use "+n others"
for big huddles.
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.
We now use comma-delimited lists of user_ids for the following
data structures in unread.js:
- unread_privates[<user_ids_string>]
- get_counts.pm_count[<user_ids_string>]
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.)
Previously, we were checking if a particular user was the current user
in dozens of places in the codebase, and correct case-insensitive
checks were not used consistently, leading to bugs like #502.
Previously, the user list would remain filtered after a user hit enter
to start composing a message to a user, leaving them in a state with a
partial user list.
Fixes#360.
The original logic for incremental presence list updating from
668d0d9dfa incorrectly attempted to
insert the user 1 spot later than its proper index in the listing.
Now that we're doing presence updates in a performant fashion, we
don't need to throttle processing these events, and in fact the
throttling of these events created a correctness problem, since we're
now doing incremental updates rather than just rerendering everything
after each event.
The code in 668d0d9dfa for removing an
existing user from the user list to update the status didn't correctly
quote the email address of the user in its jquery selector.
Whenever a user became active, this triggers an immediate presence
update event (to show that user as active). The implementation for
that event (running on the browsers of all other users in the realm)
would fully rerender the presence list, which can be an expensive
operation in a large realm, just to update the status for that one
user. This fixes that case to just remove the user from the list and
then re-insert it at the appropriate index.
