When we change a stream name, we now use the stream id as the
key to find messages we need to live update. This eliminates
some possible race conditions from two users renaming a stream.
This commit introduces message_live_update.js.
The new call stack is this:
subs.update_subscription_properties
subs.update_stream_name
message_live_update.update_stream_name
message_list.update_stream_name
The issue is that we were trying to validate the mentions before
checking that the recipient stream was valid, leading to problems
checking the membership of the stream.
Fixes#3040.
Stream descriptions are now displayed along with the name. The
autocomplete results include streams with matches in the stream
descriptions. Added styling for description in compose.css.
Fixes#2398.
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.
Using the offsetHeight getter is ~2.5x faster than
getBoundingClientRect() on what can be an expensive operation to do in
the hundreds of times.
Note: Tim thinks that this may have been different a few years ago,
since we tested fairly carefully before settling on
getBoundingClientRect, but benchmarks pretty clearly show offsetHeight
is faster today, so we should use that.
The escape key used to be intercepted if the subscription pay display
was set to “block”, but now since we use the class “show” and lack to
hide and show the overlay, the query needs to change.
We attempted a number of different approaches to solving this problem:
First, we tried using HTML5 local storage to keep track of which
browser should have created the desktop notification. This failed
because one needs locking, and it doesn't appear there is an working
locking implementation for HTML5 local storage that could allow us to
do this across tabs. See #2936 for details.
Ultimately we went with setting the message ID as a tag. Tags are
intended to be used for updating existing desktop notifications, which
means this implementation causes new notifications to flicker in and
out sometimes when multiple tabs are open, but that certainly beats
having duplicates.
Fixes#99.
Previously, the emoji reactions popovers were keyed off the
edit_content area, which is problematic because that area was
created/deleted on hover, resulting in orphaned popovers (which
wouldn't close properly normally). That had been hackishly addressed
in the original PR with the overbroad `$('.popover').remove();`. To
remove that, we fix the actions popover to always be based on an
element that exists in the page.
There probably more to do here, but this is good enough to merge emoji
reactions and iterate from here.
This commit replaces the placeholder "clipboard" button with a reaction button.
This is done on any message that can't be edited. Also, on messages sent by
the user the actions popover (toggled by the down chevron icon) contains
an option to add a reaction.
When clicked, a popover with a search bar and a list of emojis is displayed.
If the right sidebar is collapsed (the viewport is small), the popover is placed
to the left of the button.
Focus is set to the search bar. Typing in the search bar filters emojis.
Emojis with which the user has reacted to this message are highlighted.
Clicking them sends an API request to remove that reaction.
Clicking on non-highlighted emojis sends an API request to add a reaction.
When the popover loses focus it is closed.
The frontend listens for reaction events. When an add-reaction event is
received, the emoji is displayed at the bottom of the message with a
count initialized to 1. If there was an existing reaction to the message with
the same emoji, the count is incremented.
Old messages fetched from the server contain reactions.
They are displayed (along with title and count) at the bottom
of each message.
When clicking the emoji reaction at the bottom of the message, if the
user has already reacted with that emoji to this message, the reaction
is removed and the count is decremented. Otherwise, a reaction is added
and the count is incremented.
Hovering over the emoji reaction at the bottom of the message displays
a list of users who have reacted with this emoji along with the
emoji name.
Hovering over the emoji reactions at the bottom of the message displays
a button to add a reaction.
Fixes#541.
When editing a message changes the current narrow, we rerender the
narrowed view earlier in the function, so we don't need to do it here.
But we still need to rerender the home view, or the messages will be
displayed incorrectly once the user unnarrows!
Tweaked by tabbott for clarity and simplicity.
Fixes#2464.
Some of the work here was done Tomasz Kolek.
When we click on "more conversations" in "Private Messages,"
we call it being "zoomed in." Before this change, when
new PMs arrived, we would rebuild the list and zoom out
again. Now we track the zoomed_in state with a variable.
Also, if you are zoomed in and switch from one PM narrow
to another, we also keep you zoomed in.
This fix also removes some extraneous/redundant code.
Fixes: #2561
