* Refactor migration to move migrations paths to connectioneileencodes2018-01-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* `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.

| * Remove default ENGINE=InnoDB for Mysql2 adapterAlberto Almagro2017-12-112-3/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit ENGINE=InnoDB was added by default to Mysql2 adapter +create_table+ if no +options+ option was provided. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | statement due to user request (#31235) This changes `StatementTimeout` to `QueryCanceled` for PostgreSQL. In MySQL, errno 1317 (`ER_QUERY_INTERRUPTED`) is only used when the query is manually cancelled. But in PostgreSQL, `QUERY_CANCELED` error code (57014) which is used `StatementTimeout` is also used when the both case. And, we can not tell which reason happened. So I decided to introduce new error class `QueryCanceled` closer to the error code name.
* | Rename `TransactionTimeout` to more descriptive `LockWaitTimeout` (#31223)Ryuta Kamizono2017-11-271-2/+2
|/ | | | | | Since #31129, new error class `StatementTimeout` has been added. `TransactionTimeout` is caused by the timeout shorter than `StatementTimeout`, but its name is too generic. I think that it should be a name that understands the difference with `StatementTimeout`.

* MySQL: Don't lose `auto_increment: true` in the `db/schema.rb`Ryuta Kamizono2017-10-151-0/+34
| | | | | | | | | | Currently `AUTO_INCREMENT` is implicitly used in the default primary key definition. But `AUTO_INCREMENT` is not only used for single column primary key, but also for composite primary key. In that case, `auto_increment: true` should be dumped explicitly in the `db/schema.rb`. Fixes #30894.

* Don't fallback to utf8mb3 after MySQL 8.0.0Ryuta Kamizono2017-04-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `internal_string_options_for_primary_key` is used for creating internal tables in newly apps. But it is no longer needed after MySQL 8.0.0. MySQL 5.7 has introduced `innodb_default_row_format` (default `DYNAMIC`) and has deprecated `innodb_large_prefix` and `innodb_file_format`. The purpose of the deprecated options was for compatibility with earlier versions of InnoDB. https://dev.mysql.com/doc/refman/5.7/en/innodb-parameters.html#sysvar_innodb_large_prefix > innodb_large_prefix is deprecated and will be removed in a future release. innodb_large_prefix was introduced in MySQL 5.5 to disable large index key prefixes for compatibility with earlier versions of InnoDB that do not support large index key prefixes. https://dev.mysql.com/doc/refman/5.7/en/innodb-parameters.html#sysvar_innodb_file_format > The innodb_file_format option is deprecated and will be removed in a future release. The purpose of the innodb_file_format option was to allow users to downgrade to the built-in version of InnoDB in MySQL 5.1. Now that MySQL 5.1 has reached the end of its product lifecycle, downgrade support provided by this option is no longer necessary. The deprecated options has removed in MySQL 8.0.0. It is no longer needed to take care newly created internal tables as a legacy format after MySQL 8.0.0. Fixes #28730.

* `valid_type?` should accept only supported typesRyuta Kamizono2017-02-281-11/+0
| | | | | | | | | | | | | | | | | | | | `valid_type?` is used in schema dumper to determine if a type is supported. So if `valid_type?(:foobar)` is true, it means that schema dumper is allowed to create `t.foobar`. But it doesn't work. I think that `valid_type?` should accept only supported types. https://github.com/rails/rails/blob/v5.1.0.beta1/activerecord/lib/active_record/schema_dumper.rb#L135-L142 ```ruby columns.each do |column| raise StandardError, "Unknown type '#{column.sql_type}' for column '#{column.name}'" unless @connection.valid_type?(column.type) next if column.name == pk type, colspec = @connection.column_spec(column) tbl.print " t.#{type} #{column.name.inspect}" tbl.print ", #{format_colspec(colspec)}" if colspec.present? tbl.puts end ```
