Subject: [PATCH 04/57] New: Add shelfmark to sources

Since the siglum and institution name now come from the institution, the source only needs
to have the shelfmark.

However, until all the data is properly migrated, the old title and siglum fields will remain.

Subject: [PATCH 05/57] New: Migration script

This is a hacky, change-as-needed script that serves to migrate the source data from the old structure to the new, creating institutions and moving the shelfmark data to the new sources.

There is a whole bunch of sigla that get skipped (essentially all private collectors) until we figure out how they will be handled.

Don't look to closely, since there are lots of skeletons in this closet.

Subject: [PATCH 07/57] Fixed: Remove transitive import for LoginView

Previously, the LoginView import in the URLs was taken from the views.user module, instead of directly from the django auth views, because this view was also imported into the user module. (aka, a transitive import). This changes it to import from the auth views directly.

I also ran a formatter on the imports in the user module, so that's why it looks like there are more changes than there actually are!

Subject: [PATCH 08/57] Fixed: Optimize user source lookups

Previously there were several duplicated property definitions that varied only by checking whether the user was logged in. They also did the sorting in Python, rather than in the database.

This condenses all the definitions to a single one per property, and uses the expanding empty dict trick to determine whether `published=True` gets added to the filters. (Since without this, what is really desired is `published = True OR False` but without resorting to Q queries this was the simplest way to do it.)

Subject: [PATCH 09/57] The Great Feast Rework

This commit completely reworks the fetching of data for the feast detail page.

Previously, this page took several seconds to load, and generated a large number of queries, due to the complexity of the information needing to be collated.

This was rewritten to instead use two custom SQL queries that are executed directly. This means that the number of queries generated by this segment of code is now no more than two.

There are a few 'interesting' things in this, which I've tried to note in comments.

In the process, this also fixes a number of other small bugs:

Fixes #1540
Fixes #1136
Fixes #596

Subject: [PATCH 10/57] Rework Source Display

This commit reworks the source display in the templates, primarily by calling a couple helper methods on the Source model to keep the referencing consistent. The 'short heading' method displays the Institution siglum and the shelfmark, while the 'heading' displays the full institution name and the shelfmark.

The edit and create templates were reworked for the new structure and source referencing. The source display will now show the institution and the shelfmark in separate columns.

Subject: [PATCH 15/57] Tests: Disable Feast Detail Tests

Buckle up, this one's a bit messy.

This commit disables the Feast Detail tests. It turns out, after much searching and Googling and digging, that the Django Test Suite always wraps the tests in a transaction, so that the test can be easily rolled back after each one is run, and thus present a database in a known state for each individual test.

However, with the switch to running a raw SQL query, the cursor in the Feast Detail View now runs outside of this transaction. Thus to the View, the database always looks empty, even if it's running inside of the test.

I tried fixtures, TransactionTestCase, overriding methods and hacking the TestCase to prevent this behaviour, but no dice.

So for now I've marked the Feast Detail tests as "skip" so that they still appear in the runs, but are skipped because they will always fail, as they're written.

The numbers from a fresh database copy now match the numbers running on the production site, and the numbers
fetched in the browse Chants UI for the chants associated with a feast.

Subject: [PATCH 24/57] New: Private Collector Institutinos

This commit adds the ability to specify private collectors as a type of Institution.

The model constraints are set up so that you can either specify that an institution is a private collector (via a checkbox) OR they have a siglum. Both cannot be selected for the same record, but one of the two options must be selected for each record.

Institutions that do not have a siglum currently get the word "Private" prepended to the shelfmark.

All other fields are accessible for private collectors.

Alters the admin UI to make the distinction via the layout as well.
