* | | Use utf8mb4 character set by default for MySQL database (#33608)Yasuo Honda2018-09-112-3/+3
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Use utf8mb4 character set by default `utf8mb4` character set supports supplementary characters including emoji. `utf8` character set with 3-Byte encoding is not enough to support them. There was a downside of 4-Byte length character set with MySQL 5.5 and 5.6: "ERROR 1071 (42000): Specified key was too long; max key length is 767 bytes" for Rails string data type which is mapped to varchar(255) type. MySQL 5.7 supports 3072 byte key prefix length by default. * Remove `DEFAULT COLLATE` from Active Record unit test databases There should be no "one size fits all" collation in MySQL 5.7. Let MySQL server choose the default collation for Active Record unit test databases. Users can choose their best collation for their databases by setting `options[:collation]` based on their requirements. * InnoDB FULLTEXT indexes support since MySQL 5.6 it does not have to use MyISAM storage engine whose maximum key length is 1000 bytes. Using MyISAM storag engine with utf8mb4 character set would cause "Specified key was too long; max key length is 1000 bytes" https://dev.mysql.com/doc/refman/5.6/en/innodb-fulltext-index.html * References "10.9.1 The utf8mb4 Character Set (4-Byte UTF-8 Unicode Encoding)" https://dev.mysql.com/doc/refman/5.7/en/charset-unicode-utf8mb4.html "10.9.2 The utf8mb3 Character Set (3-Byte UTF-8 Unicode Encoding)" https://dev.mysql.com/doc/refman/5.7/en/charset-unicode-utf8.html "14.8.1.7 Limits on InnoDB Tables" https://dev.mysql.com/doc/refman/5.7/en/innodb-restrictions.html > If innodb_large_prefix is enabled (the default), the index key prefix limit is 3072 bytes > for InnoDB tables that use DYNAMIC or COMPRESSED row format. * CI against MySQL 5.7 Followed this instruction and changed root password to empty string. https://docs.travis-ci.com/user/database-setup/#MySQL-57 * The recommended minimum version of MySQL is 5.7.9 to support utf8mb4 character set and `innodb_default_row_format` MySQL 5.7.9 introduces `innodb_default_row_format` to support 3072 byte length index by default.

* | Don't expose `current_scope` for internal useRyuta Kamizono2018-09-111-2/+2

* | Fixes #33610Darwin D Wu2018-09-113-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | In order to avoid double assignments of nested_attributes for `has_many` relations during record initialization, nested_attributes in `create_with` should not be passed into `klass.new` and have them populate during `initialize_internals_callback` with scope attributes. However, `create_with` keys should always have precedence over where clauses, so if there are same keys in both `create_with` and `where_values_hash`, the value in `create_with` should be the one that's used.

This attribute equals to `Rails.application.config.filter_parameters` by default. ```ruby Rails.application.config.filter_parameters += [:credit_card_number] Account.last.insepct # => #<Account id: 123, credit_card_number: [FILTERED] ...> ```
* | Deprecate most methods which were never used in `DatabaseLimits`Ryuta Kamizono2018-09-051-0/+28
| | | | | | | | | | | | | | | | | | `DatabaseLimits` and those methods were introduced at 3809c80, but most methods were never used and never tested from the beginning (except `table_alias_length`, `index_name_length`, and `in_clause_length` (since 66c09372)). There is no reason to maintain unused those methods for about 8 years.

We used to stub `ActiveRecord::Base::configurations` method in those tests like `ActiveRecord::Base.stub(:configurations, @configurations) {}`. Since #33637 `ActiveRecord::Base::configurations` is a `ActiveRecord::DatabaseConfigurations` object(not a Hash object) we can't do so anymore. `ActiveRecord::DatabaseConfigurations` object builds during `ActiveRecord::Base::configurations=`. We can replace `ActiveRecord::Base.stub(:configurations, @configurations) {}` to ``` begin old_configurations = ActiveRecord::Base.configurations ActiveRecord::Base.configurations = @configurations # ... ensure ActiveRecord::Base.configurations = old_configurations end ``` Also I fixed tests in `activerecord/test/cases/tasks/legacy_database_tasks_test.rb` But currently It looks like duplication of `activerecord/test/cases/tasks/database_tasks_test.rb`. We should improve those tests or remove them. I've tried (in `activerecord/test/cases/tasks/legacy_database_tasks_test.rb` file): ``` def with_stubbed_configurations old_configurations = ActiveRecord::Base.configurations.to_h ActiveRecord::Base.configurations = @configurations ActiveRecord::Base.stub(:configurations, ActiveRecord::Base.configurations.to_h) do yield end ensure ActiveRecord::Base.configurations = old_configurations end ``` but it causes erros in tests cases. After discussion we decided to remove `activerecord/test/cases/tasks/legacy_database_tasks_test.rb` Related to #33637

| | | | | | | | | | | | | | | | | | | | | | | | This restores an ability that `update` with ids on a relation which is described at https://github.com/rails/rails/issues/33470#issuecomment-411203013. I personally think that the `update` with two arguments on a relation is not a designed feature, since that is totally not using a relation state, and also is not documented. But removing any feature should not be suddenly happened in a stable version even if that is not documented.

A three-tier config means that when Rails needed to choose a default configuration (in the case a user doesn't ask for a specific configuration) it wasn't clear to Rails which the default was. I [bandaid fixed this so the rake tasks could work](#32271) but that fix wasn't correct because it actually doubled up the configuration hashes. Instead of attemping to manipulate the hashes @tenderlove and I decided that it made more sense if we converted the hashes to objects so we can easily ask those object questions. In a three tier config like this: ``` development: primary: database: "my_primary_db" animals: database; "my_animals_db" ``` We end up with an object like this: ``` @configurations=[ #<ActiveRecord::DatabaseConfigurations::HashConfig:0x00007fd1acbded10 @env_name="development",@spec_name="primary", @config={"adapter"=>"sqlite3", "database"=>"db/development.sqlite3"}>, #<ActiveRecord::DatabaseConfigurations::HashConfig:0x00007fd1acbdea90 @env_name="development",@spec_name="animals", @config={"adapter"=>"sqlite3", "database"=>"db/development.sqlite3"}> ]> ``` The configurations setter takes the database configuration set by your application and turns them into an `ActiveRecord::DatabaseConfigurations` object that has one getter - `@configurations` which is an array of all the database objects. The configurations getter returns this object by default since it acts like a hash in most of the cases we need. For example if you need to access the default `development` database we can simply request it as we did before: ``` ActiveRecord::Base.configurations["development"] ``` This will return primary development database configuration hash: ``` { "database" => "my_primary_db" } ``` Internally all of Active Record has been converted to use the new objects. I've built this to be backwards compatible but allow for accessing the hash if needed for a deprecation period. To get the original hash instead of the object you can either add `to_h` on the configurations call or pass `legacy: true` to `configurations. ``` ActiveRecord::Base.configurations.to_h => { "development => { "database" => "my_primary_db" } } ActiveRecord::Base.configurations(legacy: true) => { "development => { "database" => "my_primary_db" } } ``` The new configurations object allows us to iterate over the Active Record configurations without losing the known environment or specification name for that configuration. You can also select all the configs for an env or env and spec. With this we can always ask any object what environment it belongs to: ``` db_configs = ActiveRecord::Base.configurations.configurations_for("development") => #<ActiveRecord::DatabaseConfigurations:0x00007fd1acbdf800 @configurations=[ #<ActiveRecord::DatabaseConfigurations::HashConfig:0x00007fd1acbded10 @env_name="development",@spec_name="primary", @config={"adapter"=>"sqlite3", "database"=>"db/development.sqlite3"}>, #<ActiveRecord::DatabaseConfigurations::HashConfig:0x00007fd1acbdea90 @env_name="development",@spec_name="animals", @config={"adapter"=>"sqlite3", "database"=>"db/development.sqlite3"}> ]> db_config.env_name => "development" db_config.spec_name => "primary" db_config.config => { "adapter"=>"sqlite3", "database"=>"db/development.sqlite3" } ``` The configurations object is more flexible than the configurations hash and will allow us to build on top of the connection management in order to add support for primary/replica connections, sharding, and constructing queries for associations that live in multiple databases.

This commit changes the behavior to first attempt to find the singular version, then attempt to find the plural version. That makes it work and find plural associations as in the example below: ``` class Post has_many :comments end class Comment belongs_to :post end ``` Previously the `:post` association reflection would only attempt to find a `comment` inverse, as opposed to both a `comment` and `comments` inverse.

This removes the overhead of those statements when saving a record with no changes, which makes workarounds like `save if changed?` unnecessary. This implementation buffers transactions inside the transaction manager and materializes them the next time the connection is used. For this to work, the adapter needs to guard all connection use with a call to `materialize_transactions`. Because of this, adapters must opt in to get this new behaviour by implementing `supports_lazy_transactions?`. If `raw_connection` is used to get a reference to the underlying database connection, the behaviour is disabled and transactions are opened eagerly, as we can't know how the connection will be used. However when the connection is checked back into the pool, we can assume that the application won't use the reference again and reenable lazy transactions. This prevents a single `raw_connection` call from disabling lazy transactions for the lifetime of the connection.

For example, if we replace ``` ActiveRecord::Associations::HasManyAssociation .any_instance .expects(:reader) .never ``` with `assert_not_called`, Minitest wisely raises ``` NameError: undefined method `reader' for class `ActiveRecord::Associations::HasManyAssociation' ``` as `:reader` comes from a deeply embedded abstract class, `ActiveRecord::Associations::CollectionAssociation`. This patch tackles this difficulty by adding `ActiveSupport::Testing::MethodCallAsserts#assert_called_on_instance_of` which injects a stubbed method into `klass`, and verifies the number of times it is called, similar to `assert_called`. It also adds a convenience method, `assert_not_called_on_instance_of`, mirroring `assert_not_called`. It uses the new method_call_assertions to replace the remaining Mocha calls in `ActiveRecord` tests. [utilum + bogdanvlviv + kspath]

The purpose of fe9547b6 is to work type casting to a value from database. We could achieve the purpose by using `read_attribute`, without using getter value. Fixes #33550.
