- Document the format for descriptor arrays - Implement the behaviour that developers have come to expect for string descriptors of indexes - Add test for handling of unique indexes (MySQL & sqlite3) - Resolve #2403 Versioned needs to convert unique indexes to non-unique for its suffixed tables, such as Foo_Live and Foo_versions. Because DataObject accepts string descriptors such as array('UniqIDX' => 'unique (Uniq)') as well as array-based descriptors, Versioned needs to recognize string descriptors. This patch accomplishes that. Before, Versioned would fail to convert string-described indexes to non-unique, resulting in run-time errors when creating a new version of an object.
