This fixes user-visible browser errors caused by trying to use the id
of messages in an empty message list.
One error could be triggered by trying to go to the end of your feed
with the End key during a reload.
Another could be triggered by trying to narrow to a stream or subject
using hotkeys while in an empty narrow.
(imported from commit a0e5456fd3b475aecac6eddd7104772baaf3aeb8)
I noticed that on chrome, calling narrow.deactivate() actually ended
up calling itself recursively due to the hashchange code not correctly
handling the fact that in Chrome if you set
window.location.hash = '#';
and then read out the value, you get '' back out.
(imported from commit 9b5047fbe0e2ac1846e5325d066c72306634c523)
What was happening is that if you un-narrowed immediately after
receiving a message (e.g. because you just sent it), the autoscroll
animation from the zfilt table would still be running after you return
to the home view, resulting in the viewport being scrolled to an
apparently random point in the home view (even though the pointer was
still in the right place).
This cancels the autoscroll animations whenever you do one of:
(1) hashchange (e.g. to go to the settings page)
(2) select a message (covers narrowing/unnarrowing as well as keyboard hotkeys)
(3) mousewheel scroll
since those are basically the cases where we set the viewport
scrolltop directly.
Arguably this should instead be something where we somehow detect
which scroll events are triggered by what and cancel for any scroll
event not from the animation or rererendering, but that seems hard.

I generally don't like this sort of state variable, but I don't see a
better solution. The codepath is that when you start out on the
subscriptions page and then click one of the left sidebar links to
narrow to something:
(1) hashchanged() would call ui.change_tab
(2) ui.change_tab triggers a gear change event
(3) The ui.js gear-changed event handler updates the hash
Resulting in the hash ending up at "#". Since there's no easy way to
pass arguments through to the event handler, we just use a global
variable inside hash_change.js to track whether we're currently
handling a hashchange event.
(imported from commit 7bb905a223b5539240fc36de7896ee8074ebc62e)
We previously had 2 mechanisms for narrowing used by the left sidebar
-- the top few links used the hashchange mechanism, while the streams
links used a custom click handler. Both were buggy -- the hashchange
one hadn't been updated to just select the first unread message,
whereas the click handler didn't change tabs.

This was biting us before when the user would leave a narrow before a

search.maybe_highlight_message() would assume a message was in the

We also have to hide the 'loading more messages' indicator when
reseting the 'load more' status because otherwise it wouldn't get
hidden like normal in the load_old_messages() continuation, causing a
load_more_messages() not to fire when re-entering a narrow.

We create a circular reference between handler functions and our
wrappers for them so that we can pass the wrapper to jQuery.off when
users pass the original handler to us. This reference-counting
system can't break all the circular references we create because
users can unbind event handlers without explicitly naming the
handlers they want to remove (they can remove all bindings on an
element, for example). For now, we hope that this memory leak isn't
too bad.

Previously, we couldn't actually unbind some event handlers. The
problem was that when a user called $.off(events, handler), the

never be unbound, effectively never cancelling them.

It's closer to a presence query than an update, and more importantly
this moves this out of Tornado -- previously Tornado was spending at
least 3ms per recipient on messages sent to the MIT realm fetching all

message sent to a popular stream the MIT realm -- but more
importantly, each such event is 100ms during which Tornado is not

We treat these exceptions the same way we treat fatal errors: report
the error message to our server and then allow the exception to reach
the top level.
We could also override document.onerror, but don't. There are a
couple of ramifications of this:
* Exceptions caused by event handlers directly attached to DOM
elements aren't handled
* Exceptions caused by code at the top level that triggers an error
(such as parse errors in our Javascript files) aren't handled
The reason we don't override document.onerror is because the
document.onerror handler has a limited interface and doesn't receive
the exception object. It only gets the message, file, and line
number of the error. Additionally, exceptions that we allow to
propogate out of blueslip trigger an onerror event when they're never
caught. In order to avoid handling the error twice (once by blueslip
and once by the onerror handler), we'd have to encode the fact that
the error has already been handled in the error message, which is
pretty ugly.

to subtract undefined from undefined and gets NaN in its test for
whether it needs to rerender.

valid values for the empty message list (the closed interval from 0 to -1).

FYI, it looks like if I accidentally tab to the "Formatting" link and

stream name in your left sidebar. j and k will still move your

the link on the sidebar! So you keep pressing enter over and
over again. Until you click somewhere or press r.

And it has the nice property that it'll only fade messages within the
neighbors range, so there's no need to update the unfading code to
support this.

To be fully responsive, we can basically never specify the width of
our container in a fixed number of pixels; otherwise we'll run into
the situation where there's an inordinate amount of wasted space on
our left and right.
So everything needs to change from, e.g. row to row-fluid,
and that has a whole cascading series of changes that that implies.

Previously we defaulted to current_msg_list.selected_id, which was
fine if you were narrowing from the home view, but if you navigated to
a narrow with no messages in it and then clicked something in the left
panel or used the search bar, it wouldn't work.
Fixes trac: #870.
