* Arel: Implemented DB-aware NULL-safe comparison (#34451)Dmytro Shteflyuk2018-11-1523-1/+492
| | | | | | | | | * Arel: Implemented DB-aware NULL-safe comparison * Fixed where clause inversion for NULL-safe comparison * Renaming "null_safe_eq" to "is_not_distinct_from", "null_safe_not_eq" to "is_distinct_from" [Dmytro Shteflyuk + Rafael Mendonça França]

* | | Add support for UNLOGGED Postgresql tablesJacob Evelyn2018-11-135-1/+110
| |/ |/| | | | | | | | | | | | | | | | | | | This commit adds support for the `ActiveRecord::ConnectionAdapters::PostgreSQLAdapter.create_unlogged_tables` setting, which turns `CREATE TABLE` SQL statements into `CREATE UNLOGGED TABLE` statements. This can improve PostgreSQL performance but at the cost of data durability, and thus it is highly recommended that you *DO NOT* enable this in a production environment.
* | Remove ensure from with_transaction_returning_statusEugene Kenny2018-11-111-4/+0
|/ | | | | | | | | | | | | | | | | The test added in 12b0b26df7560ab5199ba830586864085441508f passes even without this code since 9b8c7796a9c2048208aa843ad3dc477dffa8bdee, as the call to `id` in `remember_transaction_record_state` now triggers a `sync_with_transaction_state` which discards the leftover state from the previous transaction. This issue had already been fixed for `save!`, `destroy` and `touch` in caae79a385ce112245262a17414bcd96bea013c2, but continued to affect `save` because the call to `rollback_active_record_state!` in that method would increment the transaction level before `add_to_transaction` could clear it, preventing the fix from working correctly. As `rollback_active_record_state!` was removed entirely in 48007d5390db47fc1223f57c8e7ab3ebb7c3a3d7, this code is no longer needed.
* Fix test case for money schema defaultRyuta Kamizono2018-11-121-1/+1
| | | | | | | | Follow up a741208f80dd33420a56486bd9ed2b0b9862234a. Since a741208, `Decimal#serialize` which is superclass of `Money` type is no longer no-op, so it consistently serialize/deserialize a value as a decimal even if schema default.
* Ensure casting by decimal attribute when queryingRyuta Kamizono2018-11-121-2/+8
| | | | | | | | | | Related 34cc301f03aea2e579d6687a9ea9782afc1089a0. `QueryAttribute#value_for_database` calls only `type.serialize`, and `Decimal#serialize` is a no-op unlike other attribute types. Whether or not `serialize` will invoke `cast` is undefined in our test cases, but it actually does not work properly unless it does so for now.

* Always add records to parent of nested transactionEugene Kenny2018-11-072-1/+12
| | | | | | | | | | | | | | | | | | | When a record with transactional callbacks is saved, it's attached to the current transaction so that the callbacks can be run when the transaction is committed. Records can also be added manually with `add_transaction_record`, even if they have no transactional callbacks. When a nested transaction is committed, its records are transferred to the parent transaction, as transactional callbacks should only be run when the outermost transaction is committed (the "real" transaction). However, this currently only happens when the record has transactional callbacks, and not when added manually with `add_transaction_record`. If a record is added to a nested transaction, we should always attach it to the parent transaction when the nested transaction is committed, regardless of whether it has any transactional callbacks.

* Fix inspect with non-primary key id attributeEugene Kenny2018-11-065-3/+26
| | | | | | | | | | | The `read_attribute` method always returns the primary key when asked to read the `id` attribute, even if the primary key isn't named `id`, and even if another attribute named `id` exists. For the `inspect`, `attribute_for_inspect` and `pretty_print` methods, this behaviour is undesirable, as they're used to examine the internal state of the record. By using `_read_attribute` instead, we'll get the real value of the `id` attribute.

* Don't pass useless `table_name` to `ModelMetadata.new`Ryuta Kamizono2018-11-033-13/+4
| | | | | | | The `model_metadata` is only used if `model_class` is given. If `model_class` is given, the `table_name` is always `model_class.table_name`.
* Don't pass unused `connection` to `FixtureSet.new`Ryuta Kamizono2018-11-032-14/+11
| | | | | | | | | | The `@connection` is no longer used since ee5ab22. Originally the `@connection` was useless because it is only used in `timestamp_column_names`, which is only used if `model_class` is given. If `model_class` is given, the `@connection` is always `model_class.connection`.

* `update_columns` raises if the column is unknownSean Griffin2018-10-303-4/+15
| | | | | | | | | Previosly, `update_columns` would just take whatever keys you gave it and tried to run the update query. Most likely this would result in an error from the database. However, if the column actually did exist, but was in `ignored_columns`, this would result in the method returning successfully when it should have raised, and an attribute that should not exist written to `@attributes`.

|\ | | | | Avoid violating key constraints in fixture HABTM associations
| * Avoid violating key constraints in fixture HABTM associationsJames Le Cuirot2018-10-292-0/+7
| | | | | | | | | | | | | | | | | | When loading fixtures, Ruby 1.9's hash key ordering means that HABTM join table rows are always loaded before the parent table rows, violating foreign key constraints that may be in place. This very simple change ensures that the parent table's key appears first in the hash. Violations may still occur if fixtures are loaded in the wrong order but those instances can be avoided unlike this one.

* | Ignore empty condition on #construct_relation_for_existsr7kamura2018-10-272-1/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | At https://github.com/rails/rails/commit/fc0e3354af7e7878bdd905a95ce4c1491113af9a, ```rb relation = relation.where(conditions) ``` was rewritten to: ```rb relation.where!(condition) ``` This change accidentally changed the result of `Topic.exists?({})` from true to false. To fix this regression, first I moved the blank check logic (`opts.blank?`) from `#where` to `#where!`, because I thought `#where!` should be identical to `#where`, except that instead of returning a new relation, it adds the condition to the existing relation. But on second thought after some discussion on https://github.com/rails/rails/pull/34329, I started to think that just fixing `#construct_relation_for_exists` is more preferable than changing `#where` and `#where!`.

Since changes in the method were reverted and as mentioned in the comment https://github.com/rails/rails/pull/31819#discussion_r221847481 that titles of the tests added in #31819 don't reflect implementation I think we can remove those test for now.
* | | `assert_called_with` should require `args` argumentbogdanvlviv2018-10-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two main reasons why `assert_called_with` should require `args` argument: 1) If we want to assert that some method should be called and we don't need to check with which arguments it should be called then we should use `assert_called`. 2) `assert_called_with` without `args` argument doesn't assert anything! ```ruby assert_called_with(@object, :increment) do @object.decrement end ``` It causes false assertions in tests that could cause regressions in the project. I found this bug by working on [minitest-mock_expectations](https://github.com/bogdanvlviv/minitest-mock_expectations) gem. This gem is an extension for minitest that provides almost the same method call assertions. I was wondering whether you would consider adding "minitest-mock_expectations" to `rails/rails` instead of private `ActiveSupport::Testing::MethodCallAssertions` module. If yes, I'll send a patch - https://github.com/bogdanvlviv/rails/commit/a970ecc42c3a9637947599f2c13e3762e4b59208
