* | | | | Remove unused requireakihiro172015-10-081-1/+0
| | | | | | | | | | | | | | | | | | | | `require 'active_support/core_ext/string/filters'` was added in b3bfa36. However, it is no longer needed from 3ae981814.

|/ / / / | | | | | | | | | | | | | | | | | | | | `pk_and_sequence_for` is implemented for PG and MySQL adapters (not implemented for Sqlite3 adapter). But MySQL adapters are not using `pk_and_sequence_for` already.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Any gems or libraries which do work with serialization or YAML will ultimately need to compare these objects (albeit indirectly) to ensure correctness. These will likely never get used internally (as they're slow), but we should still expose them for others.

Instead of comparing two separate `AttributeSet` objects, and `Attribute` is now a singly linked list of every change that has happened to it. Since the attribute objects are immutable, to apply the changes we simply need to copy the head of the list. It's worth noting that this causes one subtle change in the behavior of AR. When a record is saved successfully, the `before_type_cast` version of everything will be what was sent to the database. I honestly think these semantics make more sense, as we could have just as easily had the DB do `RETURNING *` and updated the record with those if we had things like timestamps implemented at the DB layer. This brings our performance closer to 4.2, but we're still not quite there.

This means that `changed?` can be fully encapsulated on that object. Since the objects are immutable, in `changes_applied`, we can simply perform a shallow dup, instead of a deep one. I'm not sure if that will actually end up in a performance boost, but I'd like to semantically separate these concepts regardless

To fix we moved `inverse_of` and `check_validity_of_inverse!` to the `AbstractReflection` so it's available to the `ThroughReflection` without having to dup any methods. We then need to delegate `inverse_name` method in `ThroughReflection`. `inverse_name` can't be moved to `AbstractReflection` without moving methods that set the instance variable `@automatic_inverse_of`. This adds a test that ensures that `inverse_of` on a `ThroughReflection` returns the correct class name, and the correct record for the inverse relationship. Fixes #21692

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:!!!)

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
