* Refactor migration to move migrations paths to connectioneileencodes2018-01-186-165/+234
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rails has some support for multiple databases but it can be hard to handle migrations with those. The easiest way to implement multiple databases is to contain migrations into their own folder ("db/migrate" for the primary db and "db/seconddb_migrate" for the second db). Without this you would need to write code that allowed you to switch connections in migrations. I can tell you from experience that is not a fun way to implement multiple databases. This refactoring is a pre-requisite for implementing other features related to parallel testing and improved handling for multiple databases. The refactoring here moves the class methods from the `Migrator` class into it's own new class `MigrationContext`. The goal was to move the `migrations_paths` method off of the `Migrator` class and onto the connection. This allows users to do the following in their `database.yml`: ``` development: adapter: mysql2 username: root password: development_seconddb: adapter: mysql2 username: root password: migrations_paths: "db/second_db_migrate" ``` Migrations for the `seconddb` can now be store in the `db/second_db_migrate` directory. Migrations for the primary database are stored in `db/migrate`". The refactoring here drastically reduces the internal API for migrations since we don't need to pass `migrations_paths` around to every single method. Additionally this change does not require any Rails applications to make changes unless they want to use the new public API. All of the class methods from the `Migrator` class were `nodoc`'d except for the `migrations_paths` and `migrations_path` getter/setters respectively.

* Don't allow destroyed object mutation after `save` or `save!` is calledRyuta Kamizono2018-01-151-2/+24
| | | | | | | | | | Currently `object.save` will unfreeze the object, due to `changes_applied` replaces frozen `@attributes` to new `@attributes`. Since originally destroyed objects are not allowed to be mutated, `save` and `save!` should not return success in that case. Fixes #28563.
* `create_database` should not add default charset when `collation` is givenRyuta Kamizono2018-01-151-1/+1
| | | | | | | | | | | | | If `collation` is given without `charset`, it may generate invalid SQL. For example `create_database(:matt_aimonetti, collation: "utf8mb4_bin")`: ``` > CREATE DATABASE `matt_aimonetti` DEFAULT CHARACTER SET `utf8` COLLATE `utf8mb4_bin`; ERROR 1253 (42000): COLLATION 'utf8mb4_bin' is not valid for CHARACTER SET 'utf8' ``` In MySQL, charset is used to find the default collation. If `collation` is given explicitly, it is not necessary to give extra charset.

| | | | | | | | | | | | | | | | | | | | | | | | Fixes #18424. When deleting through records, it didn't take into account the conditions that may have been affecting join model table, but was defined in association definition.

| | | | | | | | | | | | | | | | | | `relation.exists?` just wants to know if there is a result or not, does not need the exact records matched. Therefore, an intermediate SELECT query for eager loading is not necessary.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently deleting through records doesn't respect `source_type`. It should not be ignored in that case. Related #23209. Fixes #24116.

| | | | | | | | | | | | | | | | | | | | | | | | Currently `last` with `offset` behaves incorrectly because `offset` can not be reversed like `limit`. Therefore, `offset` should also be handled like `limit`.

| | | | | | | | | | | | | | | | | | | | Commit 4ec5b0d was for fixing the regression #18787, but #28379 fixes #18787 as well. So 4ec5b0d is no longer necessary.

* | | | Fix newly added reflection order when redefining associationRyuta Kamizono2018-01-042-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently reflections keeps the order when first added even if when redefining association. As a result of the order, redefining through association which use newly added association will raise `HasManyThroughOrderError`. We need to redefine reflection order as well when redefining association. Fixes #31068.

This will cause a `StatementInvalid` exception later on. Solution: Use `count(:all)`, which generates a `SELECT COUNT(*)...` query independently of the association. This also includes a test case that, before the fix, broke.

This default ENGINE was lost as soon as something was passed in at +options+ option, making its goal and propagation inconsistent, as the programmer needed to remember including ENGINE=InnoDB when something was passed in. This commit removes default ENGINE as its use isn't needed anymore for current MySQL and MariaDB versions. It adds compatibility support and tests to ensure that default ENGINE is still present for migrations with version 5.1 and before. It also ensures we still dump the ENGINE option to +schema.rb+ in order to avoid inconsistencies.
