* Don't allow `where` with invalid value matches to nil valuesRyuta Kamizono2019-02-181-0/+6
| | | | | | | | | That is considered as silently leaking information. If type casting doesn't return any actual value, it should not be matched to any record. Fixes #33624. Closes #33946.
* Fix type casting column default in `change_column`Ryuta Kamizono2019-01-201-1/+13
| | | | | | | | | | | | | | Since #31230, `change_column` is executed as a bulk statement. That caused incorrect type casting column default by looking up the before changed type, not the after changed type. In a bulk statement, we can't use `change_column_default_for_alter` if the statement changes the column type. This fixes the type casting to use the constructed target sql_type. Fixes #34938.

* Enable `Style/RedundantBegin` cop to avoid newly adding redundant begin blockRyuta Kamizono2018-12-212-22/+16
| | | | | | | | | | Currently we sometimes find a redundant begin block in code review (e.g. https://github.com/rails/rails/pull/33604#discussion_r209784205). I'd like to enable `Style/RedundantBegin` cop to avoid that, since rescue/else/ensure are allowed inside do/end blocks in Ruby 2.5 (https://bugs.ruby-lang.org/issues/12906), so we'd probably meets with that situation than before.

* Rename error that occurs when writing on a readEileen Uchitelle2018-12-071-3/+3
| | | | | | | I originally named this `StatementInvalid` because that's what we do in GitHub, but `@tenderlove` pointed out that this means apps can't test for or explitly rescue this error. `StatementInvalid` is pretty broad so I've renamed this to `ReadOnlyError`.
* Add ability to prevent writes to a databaseEileen Uchitelle2018-11-301-0/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This PR adds the ability to prevent writes to a database even if the database user is able to write (ie the database is a primary and not a replica). This is useful for a few reasons: 1) when converting your database from a single db to a primary/replica setup - you can fix all the writes on reads early on, 2) when we implement automatic database switching or when an app is manually switching connections this feature can be used to ensure reads are reading and writes are writing. We want to make sure we raise if we ever try to write in read mode, regardless of database type and 3) for local development if you don't want to set up multiple databases but do want to support rw/ro queries. This should be used in conjunction with `connected_to` in write mode. For example: ``` ActiveRecord::Base.connected_to(role: :writing) do Dog.connection.while_preventing_writes do Dog.create! # will raise because we're preventing writes end end ActiveRecord::Base.connected_to(role: :reading) do Dog.connection.while_preventing_writes do Dog.first # will not raise because we're not writing end end ```

* Add support for UNLOGGED Postgresql tablesJacob Evelyn2018-11-131-0/+74
| | | | | | | | | | | This commit adds support for the `ActiveRecord::ConnectionAdapters::PostgreSQLAdapter.create_unlogged_tables` setting, which turns `CREATE TABLE` SQL statements into `CREATE UNLOGGED TABLE` statements. This can improve PostgreSQL performance but at the cost of data durability, and thus it is highly recommended that you *DO NOT* enable this in a production environment.

| * Omit BEGIN/COMMIT statements for empty transactionsEugene Kenny2018-08-132-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a transaction is opened and closed without any queries being run, we can safely omit the `BEGIN` and `COMMIT` statements, as they only exist to modify the connection's behaviour inside the transaction. 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.

| * 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`
