* Merge pull request #29495 from eugeneius/_write_attributeMatthew Draper2017-07-096-13/+19
|\ | | | | Improve the performance of writing attributes
| * Rename raw_write_attribute to write_attribute_without_type_castEugene Kenny2017-07-073-8/+8
| | | | | | | | | | | | | | | | This name more accurately describes what the method does, and also disambiguates it from `_write_attribute`, which ignores aliases. We can also make the method private, since it's not public API and only called from one place - `update_columns` - without an explicit receiver.
| * Improve the performance of writing attributesEugene Kenny2017-06-184-8/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using a similar approach to 08576b94ad4f19dfc368619d7751e211d23dcad8, this change adds a new internal `_write_attribute` method which bypasses the code that checks for attribute aliases and custom primary keys. We can use this method instead of `write_attribute` when we know that we have the name of the actual column to be updated and not an alias. This makes writing an attribute with `attribute=` about 18% faster. Benchmark: ``` begin require "bundler/inline" rescue LoadError => e $stderr.puts "Bundler version 1.10 or later is required. Please update your Bundler" raise e end gemfile(true) do source "https://rubygems.org" gem "rails", github: "rails/rails" gem "arel", github: "rails/arel" gem "sqlite3" gem "benchmark-ips" end require "active_record" ActiveRecord::Base.establish_connection(adapter: "sqlite3", database: ":memory:") ActiveRecord::Schema.define do create_table :posts, force: true do |t| end end class Post < ActiveRecord::Base end post = Post.new(id: 1) Benchmark.ips do |x| x.report("attribute=") { post.id = post.id + 1 } end ``` Before: Warming up -------------------------------------- attribute= 25.889k i/100ms Calculating ------------------------------------- attribute= 290.946k (± 3.1%) i/s - 1.476M in 5.077036s After: Warming up -------------------------------------- attribute= 30.056k i/100ms Calculating ------------------------------------- attribute= 345.088k (± 4.8%) i/s - 1.743M in 5.064264s

Before the outer transaction closes, a rollback is performed. Previously the record in the outer transaction would get marked as not persisted but the inner transaction would get persisted. ```ruby Post.transaction do post_one.save # will get rolled back Post.transaction(requires_new: true) do post_two.save # incorrectly remains marked as persisted end raise ActiveRecord::Rollback end ``` To fix this the PR changes transaction handling to have the child transaction ask the parent how the records should be marked. When there are child transactions, it will always be a SavpointTransaction because the stack isn't empty. From there we pass the parent_transaction to the child SavepointTransaction where we add the children to the parent so the parent can mark the inner transaction as rolledback and thus mark the record as not persisted. `update_attributes_from_transaction_state` uses the `completed?` check to correctly mark all the transactions as rolledback and the inner record as not persisted. ```ruby Post.transaction do post_one.save # will get rolled back Post.transaction(requires_new: true) do post_two.save # with new behavior, correctly marked as not persisted on rollback end raise ActiveRecord::Rollback end ``` Fixes #29320
| * | | Deprecate and replace `set_state` methodeileencodes2017-07-011-6/+27
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `set_state` was directly setting the transaction state instance variable. It's better to set the state via specific methods (`rollback!` and `commit!` respectively. While undocumented and untested, it's possible someone is using `set_state` in their app or gem so I've added a deprecation notice to it. No where in the app do we use `nullify!` but I wanted to keep existing behavior while replacing the method with a better pattern.

The delegation is a lower priority than delegating to `klass`, so it is pretty unclear which method is delegated to `arel`. For example, `bind_values` method was removed at b06f64c (a series of changes https://github.com/rails/rails/compare/79f71d3...b06f64c). But a relation still could respond to the method because `arel` also have the same named method (#28976). Removing the delegation will achieve predictable behavior.
