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
appears to be linear in the number of processes that are being
restarted. Therefore, restarting just Django and Tornado causes less
downtime than doing them at the same time as the other worker
processes.

Currently our test database is backed by sqlite; this commit moves
us to using postgres for our all database needs. This, in conjunction
with the patched django on github, allow us to have fewer hacks and
more true-to-life tests. It also sets the stage for testing the bulk_create
and schema search_path patches made to django.
Developers will need to run:
./tools/postgres-init-test-db
./tools/do-destroy-rebuild-test-database
this is assuming that they have already run:
./tools/postgres-init-db
./tools/do-destroy-rebuild-database
at some point on this pg_cluster. (The ordering is important; it will other-
wise complain about the south_migration table).

This change will make it so that processes related to the app.humbughq.com
server are run under supervisord, which uses a state machine model to ensure
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
6) check that nothing broke

Most of the model logic pertaining to unread counts had been in
zephyr.js, along with a couple global variables. Now the code
is encapsulated in unread.js. It was a pretty straightforward
extraction with some minor method name changes. Also, a small
bit of the logic had also been in stream_list.js.

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.

South doesn't properly deal with removing the Django User model, so
this commit redoes our South history to instead start after that
migration has already been applied. This allows us to get rid of some
annoying hacks.

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
because it creates a locale-aware collator object each time. So now,
when we can, we create and cache a locale-aware collator object.
However, this is not supported on most browsers, so we fall back to a
non-locale-aware comparison. This is not ideal, but for now we are
mostly working with English-speaking customers.

This is a V1 of this feature. For now, the only way to expand is by narrowing
to the stream---future revisions may add a manual toggle if it is found to be

Additionally, showing per-subject unread counts will be coming in a future revision

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.

We were previously having an issue where the tutorial could
be pre-empted if you got a few messages while you were first
logging in.
I have some reservations about this being slightly fragile, and a
better approach might be to just have a bit that we use to determine
whether or not you've already seen a tutorial. (Or potentially that
checks whether or not you've ever sent a message.)

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
case here.)

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.
