Leo points out that if you type a stream name, we probably want
to offer to narrow you to that stream more than we should offer
to find that stream name in the page.

On my laptop, this cuts search time from several seconds down to
a few hundred milliseconds.
If we want even more speed, we could store the ts_vector as a column
on the message database. The Postgres documentation says this will
make "searches [...] faster, since it will not be necessary to redo
the to_tsvector calls to verify index matches." Going this route
requires creating a trigger to automatically insert the appropriate
column when new rows are inserted.
Note that the full text index must be fully created before this
commit is deployed. Full text search without an index is actually
significantly slower than using the LIKE operator.

This schema migration is only for use in automated migrations. To
deploy on the production database (the migration only needs to be
done once for both of staging and prod because they share a
database), you should instead execute the following SQL manually:
$ ssh postgres.humbughq.com
$ psql
humbug=> CREATE INDEX CONCURRENTLY zephyr_message_full_text_idx ON zephyr_message USING gin(to_tsvector('english', subject || ' ' || content));
Note the addition of the "CONCURRENTLY" keyword. The problem is that
creating the index takes non-trivial time and requires a write lock
on the table while the index is being created. This would mean that
users would be unable to send messages while we were generating the
index, which isn't acceptable. We can't create the index
concurrently in the South migration because concurrent index
creations can't happen inside of a transaction and South forces a
transaction on migration functions.
Also note that this index must be created before Postgres full text
search is deployed to the app because full text search without an index
is actually much slower than plain search using the LIKE operator.

This is for allowing us to do things more complex than returning a Q
expression, needed for doing Postgres full text search.

Manual deployment steps: The same Nginx reload as for "Get rid of the
static-access-control mechanism". If deploying both commits at once,
just do it once.

We will minify our code, rather than trying to restrict who can see the
un-minified code. Removing access control first simplifies things.
Manual deployment steps:
scp servers/puppet/files/nginx/humbug-include/app root@staging.humbughq.com:/etc/nginx/humbug-include/
ssh root@staging.humbughq.com service nginx reload
and then the same for app.humbughq.com once deployed to prod.

Previously, our database was cleared between tests but the cache wasn't,
so old database data would end up in the cache and cause unit test
failures. This replaces our cache with a dummy that doesn't actually
cache any data. In the future, if we decide that our tests require an
actual cache, we can return to LocMemCache and simply empty the cache in
the tearDown method of our tests.

2) Vertically center the "Search..." placeholder

Django doesn't use this setting, but South consults it when
inspecting tables for their constraints. The fact that we store our
tables in the 'humbug' schema was causing South to fail to find our
table constraints (it was looking in the 'public' schema) and
therefore throw an exception when we try to remove the unique
constraint in migration 0002.
