| * Build a multi-statement query when inserting fixtures:Edouard CHIN2018-01-221-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - The `insert_fixtures` method can be optimized by making a single multi statement query for all fixtures having the same connection instead of doing a single query per table - The previous code was bulk inserting fixtures for a single table, making X query for X fixture files - This patch builds a single **multi statement query** for every tables. Given a set of 3 fixtures (authors, dogs, computers): ```ruby # before %w(authors dogs computers).each do |table| sql = build_sql(table) connection.query(sql) end # after sql = build_sql(authors, dogs, computers) connection.query(sql) ``` - `insert_fixtures` is now deprecated, `insert_fixtures_set` is the new way to go with performance improvement - My tests were done with an app having more than 700 fixtures, the time it takes to insert all of them was around 15s. Using a single multi statement query, it took on average of 8 seconds - In order for a multi statement to be executed, mysql needs to be connected with the `MULTI_STATEMENTS` [flag](https://dev.mysql.com/doc/refman/5.7/en/c-api-multiple-queries.html), which is done before inserting the fixtures by reconnecting to da the database with the flag declared. Reconnecting to the database creates some caveats: 1. We loose all open transactions; Inside the original code, when inserting fixtures, a transaction is open. Multple delete statements are [executed](https://github.com/rails/rails/blob/a681eaf22955734c142609961a6d71746cfa0583/activerecord/lib/active_record/fixtures.rb#L566) and finally the fixtures are inserted. The problem with this patch is that we need to open the transaction only after we reconnect to the DB otherwise reconnecting drops the open transaction which doesn't commit all delete statements and inserting fixtures doesn't work since we duplicated them (Primary key duplicate exception)... - In order to fix this problem, the transaction is now open directly inside the `insert_fixtures` method, right after we reconnect to the db - As an effect, since the transaction is open inside the `insert_fixtures` method, the DELETE statements need to be executed here since the transaction is open later 2. The same problem happens for the `disable_referential_integrity` since we reconnect, the `FOREIGN_KEY_CHECKS` is reset to the original value - Same solution as 1. , the disable_referential_integrity can be called after we reconnect to the transaction 3. When the multi statement query is executed, no other queries can be performed until we paginate over the set of results, otherwise mysql throws a "Commands out of sync" [Ref](https://dev.mysql.com/doc/refman/5.7/en/commands-out-of-sync.html) - Iterating over the set of results until `mysql_client.next_result` is false. [Ref](https://github.com/brianmario/mysql2#multiple-result-sets) - Removed the `active_record.sql "Fixture delete"` notification, the delete statements are now inside the INSERT's one - On mysql the `max_allowed_packet` is looked up: 1. Before executing the multi-statements query, we check the packet length of each statements, if the packet is bigger than the max_allowed_packet config, an `ActiveRecordError` is raised 2. Otherwise we concatenate the current sql statement into the previous and so on until the packet is `< max_allowed_packet`

* | 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.

| * Fix sqlite migrations with custom primary keysAshley Ellis Pierce2017-12-061-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, if a record was created with a custom primary key, that table could not be migrated using sqlite. While attempting to copy the table, the type of the primary key was ignored. Once that was corrected, copying the indexes would fail because custom primary keys are autoindexed by sqlite by default. To correct that, this skips copying the index if the index name begins with "sqlite_". This is a reserved word that indicates that the index is an internal schema object. SQLite prohibits applications from creating objects whose names begin with "sqlite_", so this string should be safe to use as a check. ref https://www.sqlite.org/fileformat2.html#intschema

| | | | | | | | | | | | | | | | | | | | | | | | Add support for specifying non-default operator classes in PostgreSQL indexes. An example CREATE INDEX query that becomes possible is: CREATE INDEX users_name ON users USING gist (name gist_trgm_ops); Previously it was possible to specify the `gist` index but not the custom operator class. The `add_index` call for the above query is: add_index :users, :name, using: :gist, opclasses: {name: :gist_trgm_ops}
* | Add new error class `QueryCanceled` which will be raised when canceling ↵Ryuta Kamizono2017-11-272-2/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

|/ | | | | | 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`.

* `Postgres::OID::Range` serializes to a `Range`, quote in `Quoting`Thomas Cannon2017-09-262-1/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PostgreSQL 9.1+ introduced range types, and Rails added support for using this datatype in ActiveRecord. However, the serialization of `PostgreSQL::OID::Range` was incomplete, because it did not properly quote the bounds that make up the range. A clear example of this is a `tsrange`. Normally, ActiveRecord quotes Date/Time objects to include the milliseconds. However, the way `PostgreSQL::OID::Range` serialized its bounds, the milliseconds were dropped. This meant that the value was incomplete and not equal to the submitted value. An example of normal timestamps vs. a `tsrange`. Note how the bounds for the range do not include their milliseconds (they were present in the ruby Range): UPDATE "iterations" SET "updated_at" = $1, "range" = $2 WHERE "iterations"."id" = $3 [["updated_at", "2017-09-23 17:07:01.304864"], ["range", "[2017-09-23 00:00:00 UTC,2017-09-23 23:59:59 UTC]"], ["id", 1234]] `PostgreSQL::OID::Range` serialized the range by interpolating a string for the range, which works for most cases, but does not work for timestamps: def serialize(value) if value.is_a?(::Range) from = type_cast_single_for_database(value.begin) to = type_cast_single_for_database(value.end) "[#{from},#{to}#{value.exclude_end? ? ')' : ']'}" else super end end (byebug) from = type_cast_single_for_database(value.begin) 2010-01-01 13:30:00 UTC (byebug) to = type_cast_single_for_database(value.end) 2011-02-02 19:30:00 UTC (byebug) "[#{from},#{to}#{value.exclude_end? ? ')' : ']'}" "[2010-01-01 13:30:00 UTC,2011-02-02 19:30:00 UTC)" @sgrif (the original implementer for Postgres Range support) provided some feedback about where the quoting should occur: Yeah, quoting at all is definitely wrong here. I'm not sure what I was thinking in 02579b5, but what this is doing is definitely in the wrong place. It should probably just be returning a range of subtype.serialize(value.begin) and subtype.serialize(value.end), and letting the adapter handle the rest. `Postgres::OID::Range` now returns a `Range` object, and `ActiveRecord::ConnectionAdapters::PostgreSQL::Quoting` can now encode and quote a `Range`: def encode_range(range) "[#{type_cast(range.first)},#{type_cast(range.last)}#{range.exclude_end? ? ')' : ']'}" end ... encode_range(range) #=> "['2010-01-01 13:30:00.670277','2011-02-02 19:30:00.745125')" This commit includes tests to make sure the milliseconds are preserved in `tsrange` and `tstzrange` columns
