The issue has a lot of extra details, but in short, if several
messages were sent at very close to the same time, it's possible that
the event queues will receive the "new message" events out-of-order.
This, in turn, could cause `get_events` to return an incorrectly
sorted block of messages. These would then be passed into
`message_list.add_messages`, which doesn't handle that sort of
unsorted situation correctly (in short, the `self.first.id()`
comparison checks are not accurate for that situation, since we don't
update the boundaries after the first messages is processed).
The end result of this bug was that it was possible for the message
list to be out-of-order, which in turn would cause exceptions when
scrolling with the mouse.
Fixes#6948.
This refactor will facilitate making it possible to set CSS properties
on this controls span; in particular, we're hoping to disable user
selection of the whitespace in this region.
The main side effect of this refactor is that we need to add JS code
to also hide the icon-vector-pencil element, since it's now in a new
span.
This old third party library added support
for a "mousewheel" event to detect scrolling.
However, it is not compatible with jQuery 3
and is obsolete now that there is a standard
"wheel" event that accomplishes the same thing.
For the pencil icon to appear, message_unhover has to be called before
message_hover (both in ui_init.js). This happens when the mouseleave
event is triggered on a row. But, when clicking the save button and
the edit box is hidden, the mouseleave event is not triggered and
hence message_unhover not called.
Fix this with a manual mouseleave event.
Fixes: #4287.
Despite the length of this commit, it is a very straightforward
moving of code from narrow.js -> narrow_state.js, and then
everything else is just s/narrow.foo()/narrow_state.foo()/
(with a few tiny cleanups to remove some code duplication
in certain callers).
The only new functions are simple setter/getters that
encapsulate the current_filter variable:
narrow_state.reset_current_filter()
narrow_state.set_current_filter()
narrow_state.get_current_filter()
We removed narrow.predicate() as part of this, since it was dead
code.
Also, we removed the shim for narrow_state.set_compose_defaults(),
and since that was the last shim, we removed shim.js from the app.
This fixes the /me elements to be display inline-block and inline
rather than display block with top and left properties.
This also fixes an unrelated issue with emoji reactions not being
able to be clicked on with /me messages.
Fixes: #4218.
We no longer let the left arrow put you into the message edit
UI for a message where you can only edit topics, since that is
just confusing to most users.
This change also improves error handling a bit, and it removes
an unnecessary call to rows.id().
Finally, it moves some logic out of message_list.js, so that we
don't have a circular dependency for this codepath.
Fixes#4259
This fixes the mobile web experience for Chrome on iOS.
Apparently, Chrome-on-iOS silently has a `viewport` module that
overrides and user-defined module by that name, causing all of our
code that accesses the viewport module to not work on that platform.
We fix this by renaming it.
We now sweep all active messages for avatar changes and update
the message items and re-render, rather than patching the
DOM. This avoids some quirks that happen when subsequent messages
get sent and we re-render previous messages out of the message
store.
Our approach here is similar to how we do full-name updates.
Note that this only works for people who are currently logged in.
Folks that log in after you may pick up the old full name from
the message. (I'll address this in a separate commit.)
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
We should hide the empty narrow message message whenever the narrow is
not empty, but we should only select a message if non are currently
selected.
