* Closes rails/rails#18864: Renaming transactional fixtures to transactional testsBrandon Weiss2015-03-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | I’m renaming all instances of `use_transcational_fixtures` to `use_transactional_tests` and “transactional fixtures” to “transactional tests”. I’m deprecating `use_transactional_fixtures=`. So anyone who is explicitly setting this will get a warning telling them to use `use_transactional_tests=` instead. I’m maintaining backwards compatibility—both forms will work. `use_transactional_tests` will check to see if `use_transactional_fixtures` is set and use that, otherwise it will use itself. But because `use_transactional_tests` is a class attribute (created with `class_attribute`) this requires a little bit of hoop jumping. The writer method that `class_attribute` generates defines a new reader method that return the value being set. Which means we can’t set the default of `true` using `use_transactional_tests=` as was done previously because that won’t take into account anyone using `use_transactional_fixtures`. Instead I defined the reader method manually and it checks `use_transactional_fixtures`. If it was set then it should be used, otherwise it should return the default, which is `true`. If someone uses `use_transactional_tests=` then it will overwrite the backwards-compatible method with whatever they set.

| | | | | | | | | | Before this commit, returning `false` in an ActiveRecord `before_` callback such as `before_create` would halt the callback chain. After this commit, the behavior is deprecated: will still work until the next release of Rails but will also display a deprecation warning. The preferred way to halt a callback chain is to explicitly `throw(:abort)`.

* Cleanup Transaction inheritance.Arthur Neves2014-08-051-2/+2
| | | | | | | | | Transaction class doesnt need to encapsulate the transaction state using inheritance. This removes all Transaction subclasses, and let the Transaction object controls different actions based on its own state. Basically the only actions would behave differently are `being`,`commit`,`rollback` as they could act in a savepoint or in a real transaction.

| | | | | | | | | | | | | | | | | | | | | | | | | | | rollback" We are reverting these commits, because there are other caveats related to dirty attributes not being restored when a transaction is rollback. For instance, nested transactions cannot proper restore the dirty attributes state after a rollback. At the moment, the dirty attributes are scoped by the transaction. When we call `.save` on a record, the dirty attributes will be reset even if the transaction gets rollback.

* | Restore ActiveRecord states after a rollback for models w/o callbacksGodfrey Chan2014-01-181-0/+11
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a regression (#13744) that was caused by 67d8bb9. In 67d8bb9, we introduced lazy rollback for records, such that the record's internal states and attributes are not restored immediately after a transaction rollback, but deferred until they are first accessed. This optimization is only performed when the model does not have any transactional callbacks (e.g. `after_commit` and `after_create`). Unfortunately, the models used to test the affected codepaths all comes with some sort of transactional callbacks. Therefore this codepath remains largely untested until now and as a result there are a few issues in the implementation that remains hidden until now. First, the `sync_with_transaction_state` (or more accurately, `update_attributes_from_transaction_state`) would perform the synchronization prematurely before a transaction is finalized (i.e. comitted or rolled back). As a result, when the actuall rollback happens, the record will incorrectly assumes that its internal states match the transaction state, and neglect to perform the restore. Second, `update_attributes_from_transaction_state` calls `committed!` in some cases. This in turns checks for the `destroyed?` state which also requires synchronization with the transaction stae, which causes an infnite recurrsion. This fix works by deferring the synchronization until the transaction has been finalized (addressing the first point), and also unrolled the `committed!` and `rolledback!` logic in-place (addressing the second point). It should be noted that the primary purpose of the `committed!` and `rolledback!` methods are to trigger the relevant transactional callbacks. Since this code path is only entered when there are no transactional callbacks on the model, this shouldn't be necessary. By unrolling the method calls, the intention here (to restore the states when necessary) becomes more clear.

* Assert presence of "frozen" in error message, not the full MRI message.Federico Ravasio2013-10-081-1/+3
| | | | | | | | | | Related to all the other issues regarding message independent assertions to make Rails compatible with other Ruby implementations other than MRI. The best way here would be to have a specific error raised when modifying frozen objects, like FrozenObjectError or something. But since Ruby doesn't provide such a thing, we must limit the assertion to the lowest common denominator, which is word "frozen".

| | | | | | | | | | | | `rollback_active_record_state!` tries to restore model state on `Exception` by invoking `restore_transaction_record_state` it decrement deep level by `1`. After restoring it ensure that states to be cleared and level decremented by invoking `clear_transaction_record_state`, which cause the bug: because state already reduced in `restore_transaction_record_state`. Removed double derement of transaction level and removed duplicated code which clear transaction state for top level.

According to @jeremy, this is okay to remove. He thinks it was added because at the time we didn't have much transaction state to keep track of, and he viewed it as a hack for us to track it internally, thinking it was better to ask the connection for the transaction state. Over the years we have added more and more state to track, a lot of which is impossible to ask the connection for. So it seems that this is just a relic of the passed and we will just track the state internally only.
