* | Add ability to configure cache notifications infoEileen Uchitelle2018-06-121-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This may seem like an unnecessary refactoring but some apps want / need to configure the information passed to the query cache logger. In order to do that we can add a method here that can be easily overridden by the app itself, rather than hacking the query cache logger to include that information. To override apps can call ``` def cache_notifications_info super.merge(connected_host: "hostname") end ``` This will take what's already in the query cache logger and add `@something="yea"` to the object. At GitHub we use this to log the number of queries that are cached, the connection host and the connection url.

* | Fix GROUP BY queries to apply LIMIT/OFFSET after aggregationsRyuta Kamizono2018-06-071-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If `eager_loading` is true, `apply_join_dependency` force applies LIMIT/OFFSET before JOINs by `limited_ids_for` to keep parent records count. But for aggregation queries, LIMIT/OFFSET should be applied after aggregations the same as SQL semantics. And also, we could not replace SELECT list by `limited_ids_for` when a query has a GROUP BY clause. It had never been worked since it will causes generating invalid SQL for MySQL, PostgreSQL, and probably most backends. ``` % ARCONN=postgresql be ruby -w -Itest test/cases/calculations_test.rb -n test_group_by_with_limit Using postgresql Run options: -n test_group_by_with_limit --seed 20925 # Running: E Error: CalculationsTest#test_group_by_with_limit: ActiveRecord::StatementInvalid: PG::GroupingError: ERROR: column "posts.id" must appear in the GROUP BY clause or be used in an aggregate function LINE 1: SELECT DISTINCT "posts"."id", "posts"."type" AS alias_0 FRO... ^ : SELECT DISTINCT "posts"."id", "posts"."type" AS alias_0 FROM "posts" LEFT OUTER JOIN "comments" ON "comments"."post_id" = "posts"."id" GROUP BY "posts"."type" ORDER BY "posts"."type" ASC LIMIT $1 ``` Fixes #8103. Closes #27249.
* | Fix `collection.create` to could be rolled back by `after_save`Ryuta Kamizono2018-06-072-0/+21
| | | | | | | | | | | | | | | | | | | | | | In `_create_record`, explicit `transaction` block requires rollback handling manually when `insert_record` is failed. We need to handle it in `_create_record`, not in `insert_record`, since our test cases expect a record added to target and returned even if `insert_record` is failed, Closes #31488.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rails 5.2 does not alias child joins, causing an error about duplicated table/fields: Example: Using some code like: `Post.joins(:author, :categorizations).merge(Author.select(:id)).merge(Categorization.joins(:author))` *Before this fix:* ` SELECT ... FROM "posts" INNER JOIN "authors" ON ... INNER JOIN "authors" ON ... ` *After this fix:* ` SELECT ... FROM "posts" INNER JOIN "authors" ON ... INNER JOIN "authors" "authors_categorizations" ON ... ` Before 5.2, Rails aliased the joins, but wrongfully transformed them into a LEFT OUTER JOIN. This fix will keep them as INNER JOINS, but make sure child joins are aliased, to avoid errors.

* | | Fix `save` in `after_create_commit` won't invoke extra `after_create_commit`Ryuta Kamizono2018-06-041-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since a record is already persisted in `after_create_commit`, so `save` should invoke only `after_update_commit`. This bug is caused by depending on `@_start_transaction_state` for rollback to consider whether it was `new_record` before being committed. If after commit callbacks caused another commit, the state before last commit is no longer `new_record`. Fixes #32831. Closes #18367. Closes #31106.

| | | | | | | | | | | | | | | | | | | | | | | | Since #31405, using `#increment!` with touch option instead of `#touch` to touch belongs_to association if counter cache is enabled. It caused the regression since `#increment!` won't invoke after_touch callbacks even if touch option is given. To fix the regression, make `#increment!` invokes after_touch callbacks if touch option is given. Fixes #31559. Fixes #32408.

* | Eager loading won't mutate owner recordRyuta Kamizono2018-05-251-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since #31575, `BelongsToAssociation#target=` replaces owner record's foreign key to fix an inverse association bug. But the method is not only used for inverse association but also used for eager loading/preloading, it caused some public behavior changes (#32338, #32375). To avoid any side-effect in loading associations, I reverted the overriding `#target=`, then introduced `#inversed_from` to replace foreign key in `set_inverse_instance`. Closes #32375.
* | Make force equality checking more strictly not to allow serialized attributeRyuta Kamizono2018-05-252-0/+13
|/ | | | | | | | | | | Since #26074, introduced force equality checking to build a predicate consistently for both `find` and `create` (fixes #27313). But the assumption that only array/range attribute have subtype was wrong. We need to make force equality checking more strictly not to allow serialized attribute. Fixes #32761.
* Rollback parent transaction when children fails to update (#32796)Guillaume Malette2018-05-222-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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]
* Disable foreign keys during `alter_table` for sqlite3 adapterYasuo Honda2018-05-221-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | 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. ```

* Rollback correctly restore initial record id after double saveRyuta Kamizono2018-05-191-0/+1

* Finalize transaction record state after real transactionEugene Kenny2018-05-191-0/+29
| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | 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.
