* Rollback parent transaction when children fails to update (#32796)Guillaume Malette2018-05-221-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Rollback parent transaction when children fails to update Rails supports autosave associations on the owner of a `has_many` relationship. In certain situation, if the children of the association fail to save, the parent is not rolled back. ```ruby class Employee < ActiveRecord::Base end class Company < ActiveRecord::Base has_many(:employees) end company = Company.new employee = company.employees.new company.save ``` In the previous example, if the Employee failed to save, the Company will not be rolled back. It will remain in the database with no associated Employee. I expect the `company.save` call to be atomic, and either create all or none of the records. The persistance of the Company already starts a transaction that nests it's children. However, it didn't track the success or failure of it's children in this very situation, and the outermost transaction is not rolled back. This PR makes the change to track the success of the child insertion and rollback the parent if any of the children fail. * Change the test to reflect what we expect Once #32862 is merged, rolling back a record will rollback it's state to match the state before the database changes were applied * Use only the public API to express the tests * Refactor to avoid reassigning saved for nested reflections [Guillaume Malette + Rafael Mendonça França]

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlike other databases, changing SQLite3 table definitions need to create a temporary table. While changing table operations, the original table needs dropped which caused `SQLite3::ConstraintException: FOREIGN KEY constraint failed` if the table is referenced by foreign keys. This pull request disables foreign keys by `disable_referential_integrity`. Also `disable_referential_integrity` method needs to execute `defer_foreign_keys = ON` to defer re-enabling foreign keys until the transaction is committed. https://www.sqlite.org/pragma.html#pragma_defer_foreign_keys Fixes #31988 - This `defer_foreign_keys = ON` has been supported since SQLite 3.8.0 https://www.sqlite.org/releaselog/3_8_0.html and Rails 6 requires SQLite 3.8 #32923 now - <Models>.reset_column_information added to address `ActiveModel::UnknownAttributeError` ``` Error: ActiveRecord::Migration::ForeignKeyChangeColumnTest#test_change_column_of_parent_table: ActiveModel::UnknownAttributeError: unknown attribute 'name' for ActiveRecord::Migration::ForeignKeyChangeColumnTest::Post. ```

* Finalize transaction record state after real transactionEugene Kenny2018-05-192-15/+25
| | | | | | | | | | | | | | | | | | After a real (non-savepoint) transaction has committed or rolled back, the original persistence-related state for all records modified in that transaction is discarded or restored, respectively. When the model has transactional callbacks, this happens synchronously in the `committed!` or `rolled_back!` methods; otherwise, it happens lazily the next time the record's persistence-related state is accessed. The synchronous code path always finalizes the state of the record, but the lazy code path only pops one "level" from the transaction counter, assuming it will always reach zero immediately after a real transaction. As the test cases included here demonstrate, that isn't always the case. By using the same logic as the synchronous code path, we ensure that the record's state is always updated after a real transaction has finished.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `rollback_active_record_state!` was removed from `save!` but not `save` in da840d13da865331297d5287391231b1ed39721b. I believe that leaving it in `save` was a mistake, since that commit was intended to move the rollback logic from the `save`/`save!` call to the transaction stack. As of 67d8bb963d5d51fc644d6b1ca20164efb4cee6d7 the record's original state is lazily restored the first time it's accessed after the transaction, instead of when a rollback occurs. This means that the call to `restore_transaction_record_state` here has no effect: the record's transaction level is incremented twice (in rollback_active_record_state! and `with_transaction_returning_status`), isn't decremented again until the the `ensure` block runs, and won't hit zero until the next time `sync_with_transaction_state` is called.

| | | | | | | | | | | | | | If an `ActiveRecord::Rollback` error was raised by a persistence method (e.g. in an `after_save` callback), this logic would potentially discard the original state of the record from before the transaction, preventing it from being restored later when the transaction was rolled back.

|/ | | | | | | | | | | | | | | | `after_initialize` `becomes` creates new object and copies attributes from the receiver. If new object has mutation tracker which is created in `after_initialize`, it should be cleared since it is for discarded attributes. But if the receiver doesn't have mutation tracker yet, it will not be cleared properly. It should be cleared regardless of whether the receiver has mutation tracker or not. Fixes #32867.
* Fix ActiveRecord::AttributeMethods::Dirty documentation [ci skip]Kieran Trezona-le Comte2018-05-071-20/+58
| | | | | | | | | | | | | | | Previously the documentation for the newly introduced (in 5.1) AR::Dirty methods was misleading, as it stated the the new methods were aliases for the old methods. This was false, and caused confusion when the differences in their implementation became apparent. This change attempts to describe the behaviour of these methods more accurately, also noting when they are likely to be useful (i.e. before or after saving a record). This change also makes minor updates to consistently format the documentation of this API, in accordance with the API Documentation Guidelines.
* Fix logic on disabling commit callbacksBrian Durand2018-05-041-1/+1
| | | | Commit callbacks are intentionally disabled when errors occur when calling the callback chain in order to reset the internal record state. However, the implicit order of operations on the logic for checking if callbacks are disabled is wrong. The result is that callbacks can be unexpectedly when errors occur in transactions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The documentation previously claimed that `db/schema.rb` was "the authoritative source for your database schema" while simultaneously also acknowledging that the file is generated. These two statements are incongruous and the guides accurately call out that many database constructs are unsupported by `schema.rb`. This change updates the comment at the top of `schema.rb` to remove the assertion that the file is authoritative. The documentation also previously referred vaguely to "issues" when re-running old migrations. This has been updated slightly to hint at the types of problems that one can encounter with old migrations. In sum, this change attempts to more accurately capture the pros, cons, and shortcomings of the two schema formats in the guides and in the comment at the top of `schema.rb`.

Previously, when building the object via .new, the intermediate object would be created instead of just being built. Here's an example: Given a GameBoard, that has_one Owner and Collection through Game. The following line would cause a game object to be created in the database. GameBoard.new(owner: some_owner, collection: some_collection) Whereas, if passing only one of those associations into `.new` would cause the Game object to be built and not created in the database. Now the above code will only build the Game object, and not save it.

However, supporting identity data type will make `prefetch_primary_key?` returns `false` then no primary key column name added.
