This PR moves the `schema_migration` to `migration_context` so that we can access the `schema_migration` per connection. This does not change behavior of the SchemaMigration if you are using one database. This also does not change behavior of any public APIs. `Migrator` is private as is `MigrationContext` so we can change these as needed. We now need to pass a `schema_migration` to `Migrator` so that we can run migrations on the right connection outside the context of a rake task. The bugs this fixes were discovered while debugging the issues around the SchemaCache on initialization with multiple database. It was clear that `get_all_versions` wouldn't work without these changes outside the context of a rake task (because in the rake task we establish a connection and change AR::Base.connection to the db we're running on). Because the `SchemaCache` relies on the `SchemaMigration` information we need to make sure we store it per-connection rather than on ActiveRecord::Base. [Eileen M. Uchitelle & Aaron Patterson] |
