* Apply subsecond precision on assignment when using TZ aware attributesSean Griffin2015-09-241-1/+1
| | | | | | | | | | | When a time object was assigned to a datetime column, the decorator for TZ aware attributes wouldn't call super, so when using a database without support for subsecond precision, the nanosecond would not be truncated, leading to the value being marked as changed. Interestingly, this also shows our new implementation of dirty checking to be more robust than the old one (with less code and better performance! :tada:!!!)
* We still need to reset `@changed_attributes` in `changes_applied`Sean Griffin2015-09-241-0/+2
| | | | | | When I removed the call to `super` to avoid the setting of `@previous_changes`, I forgot to duplicate the other part of that behavior, which led to failing tests
* Improve the performance of `save` and friendsSean Griffin2015-09-242-2/+39
| | | | | | | | | | | | | | | | | | | | | | The biggest source of the performance regression in these methods occurred because dirty tracking required eagerly materializing and type casting the assigned values. In the previous commits, I've changed dirty tracking to perform the comparisons lazily. However, all of this is moot when calling `save`, since `changes_applied` will be called, which just ends up eagerly materializing everything, anyway. With the new mutation tracker, it's easy to just compare the previous two hashes in the same lazy fashion. We will not have aliasing issues with this setup, which is proven by the fact that we're able to detect nested mutation. Before: User.create! 2.007k (± 7.1%) i/s - 10.098k After: User.create! 2.557k (± 3.5%) i/s - 12.789k Fixes #19859
* Encapsulate a lot of the logic from `Dirty` in an objectSean Griffin2015-09-243-25/+65
| | | | | | | | | In order to improve the performance of dirty checking, we're going to need to duplicate all of the `previous_` methods in Active Model. However, these methods are basically the same as their non-previous counterparts, but comparing `@original_attributes` to `@previous_original_attributes` instead of `@attributes` and `@original_attributes`. This will help reduce that duplication.
* Clean up the implementation of AR::DirtySean Griffin2015-09-249-89/+70
| | | | | | | | | | | | | This moves a bit more of the logic required for dirty checking into the attribute objects. I had hoped to remove the `with_value_from_database` stuff, but unfortunately just calling `dup` on the attribute objects isn't enough, since the values might contain deeply nested data structures. I think this can be cleaned up further. This makes most dirty checking become lazy, and reduces the number of object allocations and amount of CPU time when assigning a value. This opens the door (but doesn't quite finish) to improving the performance of writes to a place comparable to 4.1

This patch fixes that issue ensuring that any timestamp assigned as an attribute is converted to column precision under the attribute.

These new methods allow us to change `conn.tables` in the future to only return tables and no views. Same for `conn.table_exists?`. The goal is to provide the following introspection methods on the connection: * `tables` * `table_exists?` * `views` * `view_exists?` * `data_sources` (views + tables) * `data_source_exists?` (views + tables)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | We should probably review the usage of these constants and decide whether we want to be more transparent about which things come from Active Model vs Active Record, as this is meaningful information as to whether there is database specific behavior or not.
* | | | Simplify the implementation of Active Model's type registrySean Griffin2015-09-211-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Things like decorations, overrides, and priorities only matter for Active Record, so the Active Model registry can be implemented much more simply. At this point, I wonder if having Active Record's registry inherit from Active Model's is even worth the trouble? The Active Model class was also missing test cases, which have been backfilled. This removes the error when two types are registered with the same name, but given that Active Model is meant to be significantly more generic, I do not think this is an issue for now. If we want, we can raise an error at the point that someone tries to register it.
* | | | Various stylistic nitpicksSean Griffin2015-09-216-42/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We do not need to require each file from AM individually, the type module does that for us. Even if the classes are extremely small right now, I'd rather keep any custom classes needed by AR in their own files, as they can easily have more complex changes in the future.
