* Merge pull request #33878 from kamipo/fallback_to_unprepared_statementRyuta Kamizono2018-09-155-7/+19

| * Fallback to unprepared statement only when bind params limit is exceededRyuta Kamizono2018-09-145-7/+19
| | | | | | | | | | | | | | | | | | | | | | This is a follow up and/or an alternative of #33844. Unlike #33844, this would attempt to construct unprepared statement only when bind params limit (mysql2 65535, pg 65535, sqlite3 249999) is exceeded. I only defined 65535 as the limit, not defined 249999 for sqlite3, since it is an edge case, I'm not excited to add less worth extra code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Once #33608 merged If users create a new database using MySQL 5.1.x, it will fail to create databases since MySQL 5.1 does not know `utf8mb4` character set. This pull request removes `encoding: utf8mb4` from `mysql.yml.tt` to let create_database method handles default character set by MySQL server version. `supports_longer_index_key_prefix?` method will need to validate if MySQL 5.5 and 5.6 server configured correctly to support longer index key prefix, but not yet.

|\ \ \ | |/ / |/| | Eager loading/preloading should be worked regardless of large number of records
| * | Eager loading/preloading should be worked regardless of large number of recordsRyuta Kamizono2018-09-126-5/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 213796f, bind params are used for IN clause if enabled prepared statements. Unfortunately, most adapter modules have a limitation for # of bind params (mysql2 65535, pg 65535, sqlite3 250000). So if eager loading large number of records at once, that query couldn't be sent to the database. Since eager loading/preloading queries are auto-generated by Active Record itself, so it should be worked regardless of large number of records like as before. Fixes #33702.
* | | Add mention about `ActiveRecord::Base::filter_attributes` to the changelog entrybogdanvlviv2018-09-122-8/+13
| | | | | | | | | | | | | | | Also remove `# :nodoc:` for `ActiveRecord::Core::ClassMethods` in order to show non-nodoc methods in that module on the api docs http://edgeapi.rubyonrails.org
* | | Build string set when `filter_attributes` is assignedbogdanvlviv2018-09-121-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | It would allow `filter_attributes` to be reused across multiple calls to `#inspect` or `#pretty_print`. - Add `require "set"` - Remove `filter_attributes` instance reader. I think there is no need to keep it.
* | | DRY `activerecord/lib/active_record/core.rb` and fix testsbogdanvlviv2018-09-122-20/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Move ``` filter_attributes = self.filter_attributes.map(&:to_s).to_set filter_attributes.include?(attribute_name) && !read_attribute(attribute_name).nil? ``` to private method. - Fix tests in `activerecord/test/cases/filter_attributes_test.rb` - Ensure that `teardown` sets `ActiveRecord::Base.filter_attributes` to previous state. - Ensure that `Admin::Account.filter_attributes` is set to previous state in the "filter_attributes could be overwritten by models" test.

* | | Fix query cache to load before first requestEileen Uchitelle2018-09-121-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a test app we observed that the query cache was not enabled on the first request. This was because the query cache hooks are installed on load and active record is loaded in the middle of the first request. If we remove the `on_load` from the railtie the query cache hooks will be installed before the first request, allowing the cache to be enabled on that first request. This is ok because query cache doesn't load anything else, only itself so we're not eager loading all of active record before the first request, just the query cache hooks. [Eileen M.

* | | Use utf8mb4 character set by default for MySQL database (#33608)Yasuo Honda2018-09-117-11/+18
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* | Fixes #33610Darwin D Wu2018-09-115-7/+61
| | | | | | | | | | | | | | | | | | | | | | | | 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.

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.
