* Omit BEGIN/COMMIT statements for empty transactionsEugene Kenny2018-08-1317-17/+185
| | | | | | | | | | | | | | | | | | | | | | 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.
* Use strings instead of symbols on calls to decorate_matching_attribute_typesDillon Welch2018-08-102-2/+2
| | | | | | The first thing this method does is run on the argument. This change passes in a string so we don't allocate a bunch of unnecessary extra strings by calling to_s on a symbol over and over.

| | | | | | | | | | This reverts commit d162188dd662a7d9f62ba8431474f50bc35e3e93, reversing changes made to 3576782888c307e3e192c44e332b957cd1174128. Reason: #24131 conflicts the #5153's default order contract, it means that existing apps would be broken by that change. We don't want to break existing apps without a deprecation cycle.

* Avoid extra scoping when using `Relation#update`Ryuta Kamizono2018-07-313-3/+9
| | | | | | | | | | | | | | Since 9ac7dd4, class level `update`, `destroy`, and `delete` were placed in the `Persistence` module as class methods. But `Relation#update` without passing ids which was introduced at #11898 is not a class method, and it was caused the extra scoping regression #33470. I moved the relation method back into the `Relation` to fix the regression. Fixes #33470.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Step 6 in #33162 When using Mocha like this: `ActiveRecord::Base.expects(:establish_connection).with(some_args)`, the expectations created look something like this: ``` @expectations= [#<Expectation:0x561350d968e0 expected exactly once, not yet invoked: ActiveRecord::Base.establish_connection("adapter" => "mysql2", "database" => nil) >, #<Expectation:0x561350dab8f8 allowed any number of times, not yet invoked: ActiveRecord::Base.establish_connection(any_parameters) >, #<Expectation:0x561350dc30c0 allowed any number of times, not yet invoked: ActiveRecord::Base.connection(any_parameters) >] ``` Minitest mocking (and the way we use it in `MethodCallAssertions`) expressly refuses to facilitate such permissiive expectations, insisting that all calls be specified in the actual expected order. This patch replaces such calls to `Mocha#expects` with `ActiveSupport::Testing::MethodCallAssertions` and specifies all expected calls in the epxected order.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since #29301, delegating to klass methods in the `scope` block would cause extra scoping by the receiver itself. The extra scoping would always override intermediate scoping like `unscoped` and caused the regression #33387. To keep the original scoping behavior, should avoid the extra scoping in the `scope` block. Fixes #33387.
