This is a big change affecting lots of areas:
* Pipeline no longer deals with JS (though it still minifies CSS)
* A new script, tools/minify-js (called from update-prod-static),
minifies JavaScripts
* A command-line argument --prev-deploy, if passed to minify-js or
update-prod-static, is used to copy minified JS from a previous
deploy (i.e., a previous git checkout), if the source files have
not changed
* update-deployment passes --prev-deploy
* Scripts are now included with the minified_js template tag, rather
than Pipeline's compressed_js
Also, as a side benefit of this commit, our Handlebars templates will
no longer be copied into prod-static/ and accessible in production.
Unminification is probably broken, but, per Zev and Trac ticket #1377,
it wasn't working perfectly before this change either.
(Based on code review, this commit has been revised to:
* Warn if git returns an error in minify-js
* Add missing output redirects in update-prod-static
* Use DEPLOY_ROOT instead of manually constructing that directory
* Use old style formatting)

- FF doesn't allow iconUrl to be of a different origin, so it won't display

Per http://docs.python.org/2/library/os.html#os.getlogin, getlogin()
only works when you have an associated controlling tty.
This script didn't work previously because when we do deployments there
is no tty. Thus, we switch to the alternative mechanism for determining
the current username described on the page linked above.

If you're running this as a user other than "humbug" on a deployed server,
you're going to have a bad time.
Specifically, memcached won't work, and other undefined behaviour may
occur.
So here we add a check and error out if you run this script on an
app_frontend as non-"humbug".

Otherwise we end up running Tornado against the _previous_ version of
our code!
Testing of using supervisorctl to stop and then start a process shows
it takes about the same amount of time as doing a supervisorctl
restart, so there's no reason not to split the two commands apart and
make it super clear that nothing is running at the time that we move
the deployment symlink.

Does a test-all using /tmp.
Not safe to run with other tests simultaneously.
You use it just like tools/review, and on a successful test-all
it will submit the code review, without tying up your git working directory.
It depends on new patches to the acrefoot-bulk_create_with_id-1.5.1 branch of
django. Updating this is the [manual] step required. Since test-all doesn't happen
on staging or prod, this is not required for this commit to be deployed, but other
django patches will help with the SSL connection errors we've been seeing.

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

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.

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.
