* Add schema cache to new connection pool after forkEugene Kenny2015-05-171-1/+3
| | | | | | | | | | | | | | Active Record detects when the process has forked and automatically creates a new connection pool to avoid sharing file descriptors. If the existing connection pool had a schema cache associated with it, the new pool should copy it to avoid unnecessarily querying the database for its schema. The code to detect that the process has forked is in ConnectionHandler, but the existing test for it was in the ConnectionManagement test file. I moved it to the right place while I was writing the new test for this change.

| * AR::ConPool - remove synchronization around connection cache.thedarkone2015-05-142-80/+304
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Renamed `@reserved_connections` -> `@thread_cached_conns`. New name clearly conveys the purpose of the cache, which is to speed-up `#connection` method. The new `@thread_cached_conns` now also uses `Thread` objects as keys (instead of previously `Thread.current.object_id`). Since there is no longer any synchronization around `@thread_cached_conns`, `disconnect!` and `clear_reloadable_connections!` methods now pre-emptively obtain ownership (via `checkout`) of all existing connections, before modifying internal data structures. A private method `release` has been renamed `thread_conn_uncache` to clear-up its purpose. Fixed some brittle `thread.status == "sleep"` tests (threads can go into sleep even without locks).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If your STI class looks like this: ```ruby class Company < ActiveRecord::Base self.store_full_sti_class = false class GoodCo < Company end class BadCo < Company end end ``` The expectation (which is valid) is that the `type` in the database is saved as `GoodCo` or `BadCo`. However, another expectation should be that setting `type` to `GoodCo` would correctly instantiate the object as a `Company::GoodCo`. That second expectation is what this should fix.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `db:schema:cache:dump` rake task dumps the database schema structure to `db/schema_cache.dump`. If this file is present, the schema details are loaded into the currently checked out connection by a railtie while Rails is booting, to avoid having to query the database for its schema. The schema cache dump is only applied to the initial connection used to boot the application though; other connections from the same pool are created with an empty schema cache, and still have to load the structure of each table directly from the database. With this change, a copy of the schema cache is associated with the connection pool and applied to connections as they are created.
