We let supervisor create the socket for us by making humbug-django a
fcig-program. Unfortunately, supevisor doesn't support putting
fcgi-programs in groups (see
https://github.com/Supervisor/supervisor/issues/148), so we have to
restart tornado and django separately.
To deploy, copy the config files over and restart nginx and
supervisor (via stopping and then starting it because restart is
broken). I believe the automated restart as part of
update-deployment will fail because of the way supervisor treats
programs in groups. If so, after restarting supervisor, you will
also need to run restart-server manually to fill the caches and then
delete the lock directory in humbug-deployments.

The amount of process downtime during a supervisord-mediated restart

This change will make it so that processes related to the app.humbughq.com

that programs are running. It also ensure process startup order.
We will need to manually switch the old way of running server (in screen) into
this new way of doing things, on both staging and prod (app_frontend.pp has been
updated appropriately). This means:
1) cp servers/puppet/modules/humbug/files/supervisord/conf.d/humbug.conf /etc/supervisord/conf.d
2) installing the supervisor package.
3) killing those while loops in that screen session
4) mkdir /var/log/humbug (as root)
5) /etc/init.d/supervisord start

The only known outstanding bug with this is that it doesn't properly
handle the updating of a message's highlighting/presence in a narrowed
view (e.g. in theory, a message should disappear if it is edited such
that its subject doesn't match your narrow or it no longer matches
your search). I think I'll just open a trac ticket about that once
this is merged, since it's a little hairy to deal with and kinda a
marginal use case.
Also it's not pretty, but that should be easy to tweak once we get the
framework merged.

This is a prefactoring to eventually eliminate the home_unread_messages
global variable. More commits to follow.
In order to set up process_loaded_for_unread() not to modify
global variable to get its job done, we want to pull it out of
add_messages(), so that add_messages() doesn't have to pass back
state to the 9 different places in the codebase where it's called.
There are only 2 places where process_loaded_for_unread() get
called after this commit.
In order to facilitate pulling up process_loaded_for_unread(), I
made it so that the contract for add_messages() was to accept
already-hydrated messages. This way I could hydrate the messages
before calling process_loaded_for_unread() without have to
worry about double-caching them in add_messages. This will
slightly improve performance, but it was mostly done for code
clarity.

The String.localeCompare function is really slow, at least partially

when we can, we create and cache a locale-aware collator object.

non-locale-aware comparison. This is not ideal, but for now we are
mostly working with English-speaking customers.

We accidentally lost this when we did the User/UserProfile merge (this
commit also deletes the old code to add the auth_user index in
do-destroy-rebuild-database).
This below is mostly just notes for future reference, but when
deploying this change to staging, we should consider running the
following instead of using the migration directly:
CREATE UNIQUE INDEX CONCURRENTLY zephyr_userprofile_email_uniq ON zephyr_userprofile(email);
ALTER TABLE zephyr_userprofile ADD CONSTRAINT zephyr_userprofile_email_uniq UNIQUE USING INDEX zephyr_userprofile_email_uniq;
CREATE INDEX CONCURRENTLY zephyr_userprofile_email ON zephyr_userprofile(email);
But I think it might be the case that it's fine to just run it
directly, since the ALTER TABLE part seems to hang if there's an open
transaction working on a UserProfile object anyway.

At Ksplice we used /usr/bin/python because we shipped dependencies as Debian /
Red Hat packages, which would be installed against the system Python. We were
also very careful to use only Python 2.3 features so that even old system
Python would still work.
None of that is true at Humbug. We expect users to install dependencies
themselves, so it's more likely that the Python in $PATH is correct. On OS X
in particular, it's common to have five broken Python installs and there's no
expectation that /usr/bin/python is the right one.
The files which aren't marked executable are not interesting to run as scripts,
so we just remove the line there. (In general it's common to have libraries
that can also be executed, to run test cases or whatever, but that's not the

So here's the reproduction recipe:
(1) Find a narrow that doesn't have any messages since 4 days ago
(2) Directly visit that narrow in your browser (or wait for someone to
do a deploy and thus auto-reload)
(3) Wait until load_old_messages has been called at least once
(4) Un-narrow
(5) Scroll up, and notice that the 400 most recent messages are above
sets of older messages.
The cause is that the code in add_messages assumed that
selected_message_id was within the range of message already in the
home view. This is true in most cases where add_message is being
called, but it is not true in the case that the user was in a narrowed
view containing only very old messages (And thus selected_message_id
would be older than everything in the home view).
We can fix this by tracking persistent_message_id separately and using
that for the relevant test in add_messages.

Embedding this in index.html won't work anymore, because the Django FastCGI and
the Tornado servers might have been started at different times.

If the client is not composing a message, we can just force a page
reload. However, if he is composing a message, we must preserve that
message while still reloading as soon as possible.
We take the following approach: if the client has not completed the
composition after 5 minutes, do a compose-preserving reload
(described below). If he sends the message before the timeout
expires, reload the page after a successful send. If the send fails
(not due to server timeout), however, we do a compose-perserving
reload in case the error was due to the data format changing. If the
send failed due to server timeout, we don't reload because the reload
will probably also fail.
In a compose-preserving reload, we redirect to an URI that has a
fragment indicating we are doing a reload and containing all the
necessary information for restoring the compose window to its
previous state. On page load, we check the fragment to see if we
just did a compose-preserving reload, and, if we did, we restore the
compose window (or just try the send again in the case of send
failure). The URI fragment looks like:

We had this fascinating behavior where pressing a down arrow near the
end of the page would advance the pointer, call recenter_view, which
would trigger a scroll event, which would call keep_pointer_in_view,
which would notice that we were at the end of the page and advance the
pointer again!
I split out that last part into its own function which is only called
on mousewheel events.

This also helps us manage checking, case-insensitive, for
subscriptions while preserving the casing used by the class creator
for display.
It also fixes a bug where the class_list would become out of sync with
your true subscriptions, allowing you to appear to send messages to
classes to which you had unsubscribed.

Rather than trying to keep track of whether the last thing that
happened was an input area being focused (which had all kinds of
bugs), just detect whether we're in an input area using the
appropriate jquery selector. Hopefully this has OK performance.

It is confusing, and clicking on it should behave like clicking
elsewhere in the message.

The new version is now the only codepath that we use in order to start

This is somewhat experimental and we may need to work on the condition
when it shows up (or move it elsewhere).
Also, maybe it should say "Today/Yesterday" for times super close to
now -- the main issue with doing this is whether it needs to update
without your reloading the page to avoid being super confusing.

It causes problems when [un]narrowing, and we already do the rest of formatting
on the server side.

Instead just cd to the repository root for pyflakes. This is a marginally
worse user experience, but should work on Mac OS where we don't have readlink

Amazingly the choice of collation affects whether Django returns bytestring or Unicode values.
