* Add documentation for `:collation` column option (#33733)Nate Pinsky2018-08-271-0/+3
| | | | | | | | | | | | | * Add documentation for `:collation` option The table definition supports a `:collation` option for string and text columns, but this is not documented anywhere that I could find. I'm not sure if the "If not specified" part is accurate. From [this PR](https://github.com/rails/rails/commit/1515c4d98da3f730ef971fa5a13cad828bd9bef4), it looks like it passes `nil` and lets the database handle the collation, but I'm happy to change it if I misread the code.

| * Prevent deadlocks when waiting for connection from pool.Brent Wheeldon2018-03-231-1/+3
| | | | | | | | | | When a thread that had the load interlock but was blocked waiting to check a connection out of the connection pool but all of the threads using the available connections were blocked waiting to obtain the load interlock an `ActiveRecord::ConnectionTimeoutError` exception was be thrown by the thread waiting for the connection. When waiting for the connection to check out we should allow loading to proceed to avoid this deadlock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `Relation::Merger` has a problem that order values would be merged as nested array. That was caused an issue #33664 since if array value is passed to `order` and first element in the array includes `?`, the array is regarded as a prepared statement and bind variables. https://api.rubyonrails.org/classes/ActiveRecord/Sanitization/ClassMethods.html#method-i-sanitize_sql_for_order Just merging that as splat args like other values would fix the issue. Fixes #33664.

* | Avoid extra scoping when using `Relation#update`Ryuta Kamizono2018-07-312-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
