* Ensure Active Record connection consistencyschneems2014-01-091-1/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently Active Record can be configured via the environment variable `DATABASE_URL` or by manually injecting a hash of values which is what Rails does, reading in `database.yml` and setting Active Record appropriately. Active Record expects to be able to use `DATABASE_URL` without the use of Rails, and we cannot rip out this functionality without deprecating. This presents a problem though when both config is set, and a `DATABASE_URL` is present. Currently the `DATABASE_URL` should "win" and none of the values in `database.yml` are used. This is somewhat unexpected to me if I were to set values such as `pool` in the `production:` group of `database.yml` they are ignored. There are many ways that active record initiates a connection today: - Stand Alone (without rails) - `rake db:<tasks>` - ActiveRecord.establish_connection - With Rails - `rake db:<tasks>` - `rails <server> | <console>` - `rails dbconsole` We should make all of these behave exactly the same way. The best way to do this is to put all of this logic in one place so it is guaranteed to be used. Here is my prosed matrix of how this behavior should work: ``` No database.yml No DATABASE_URL => Error ``` ``` database.yml present No DATABASE_URL => Use database.yml configuration ``` ``` No database.yml DATABASE_URL present => use DATABASE_URL configuration ``` ``` database.yml present DATABASE_URL present => Merged into `url` sub key. If both specify `url` sub key, the `database.yml` `url` sub key "wins". If other paramaters `adapter` or `database` are specified in YAML, they are discarded as the `url` sub key "wins". ``` ### Implementation Current implementation uses `ActiveRecord::Base.configurations` to resolve and merge all connection information before returning. This is achieved through a utility class: `ActiveRecord::ConnectionHandling::MergeAndResolveDefaultUrlConfig`. To understand the exact behavior of this class, it is best to review the behavior in activerecord/test/cases/connection_adapters/connection_handler_test.rb though it should match the above proposal.
* Automatically maintain test database schemaJon Leighton2014-01-021-0/+2
| | | | | | | | | | | | | | * Move check from generated helper to test_help.rb, so that all applications can benefit * Rather than just raising when the test schema has pending migrations, try to load in the schema and only raise if there are pending migrations afterwards * Opt out of the check by setting config.active_record.maintain_test_schema = false * Deprecate db:test:* tasks. The test helper is now fully responsible for maintaining the test schema, so we don't need rake tasks for this. This is also a speed improvement since we're no longer reloading the test database on every call to "rake test".

| | | | | | | | | | We discussed that the auto explain feature is rarely used. This PR removes only the automatic explain. You can still display the explain output for any given relation using `ActiveRecord::Relation#explain`. As a side-effect this should also fix the connection problem during asset compilation (#9385). The auto explain initializer in the `ActiveRecord::Railtie` forced a connection.
