|\ | | | | Sync transaction state when accessing primary key
| * Sync transaction state when accessing primary keyEugene Kenny2017-07-091-3/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a record is modified inside a transaction, it must check the outcome of that transaction before accessing any state which would no longer be valid if it was rolled back. For example, consider a new record that was saved inside a transaction which was later rolled back: it should be restored to its previous state so that saving it again inserts a new row into the database instead of trying to update a row that no longer exists. The `id` and `id=` methods defined on the PrimaryKey module implement this correctly, but when a model uses a custom primary key, the reader and writer methods for that attribute must check the transaction state too. The `read_attribute` and `write_attribute` methods also need to check the transaction state when accessing the primary key.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's say you have a nested transaction and both records are saved. Before the outer transaction closes, a rollback is performed. Previously the record in the outer transaction would get marked as not persisted but the inner transaction would get persisted. ```ruby Post.transaction do post_one.save # will get rolled back Post.transaction(requires_new: true) do post_two.save # incorrectly remains marked as persisted end raise ActiveRecord::Rollback end ``` To fix this the PR changes transaction handling to have the child transaction ask the parent how the records should be marked. When there are child transactions, it will always be a SavpointTransaction because the stack isn't empty. From there we pass the parent_transaction to the child SavepointTransaction where we add the children to the parent so the parent can mark the inner transaction as rolledback and thus mark the record as not persisted. `update_attributes_from_transaction_state` uses the `completed?` check to correctly mark all the transactions as rolledback and the inner record as not persisted. ```ruby Post.transaction do post_one.save # will get rolled back Post.transaction(requires_new: true) do post_two.save # with new behavior, correctly marked as not persisted on rollback end raise ActiveRecord::Rollback end ``` Fixes #29320
* Deprecate and replace `set_state` methodeileencodes2017-07-011-0/+38
| | | | | | | | | | | | | `set_state` was directly setting the transaction state instance variable. It's better to set the state via specific methods (`rollback!` and `commit!` respectively. While undocumented and untested, it's possible someone is using `set_state` in their app or gem so I've added a deprecation notice to it. No where in the app do we use `nullify!` but I wanted to keep existing behavior while replacing the method with a better pattern.

| | | | | | | | | | | | | | | This clears the transaction record state when the transaction finishes with a `:committed` status. Considering the following example where `name` is a required attribute.

* Silence deprecation warning from force reloadPrem Sichanugrist2015-07-161-2/+2
| | | | | | | | | | | | We deprecate the support for passing an argument to force reload in 6eae366d0d2e5d5211eeaf955f56bd1dc6836758. That led to several deprecation warning when running Active Record test suite. This commit silence the warnings by properly calling `#reload` on the association proxy or on the association object instead. However, there are several places that `ActiveSupport::Deprecation.silence` are used as those tests actually tests the force reload functionality and will be removed once `master` is targeted next minor release (5.1).
* 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.

* Reverts "Fix bugs with changed attributes tracking when transaction gets ↵Arthur Neves2014-05-091-42/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
