* Don't calculate all in-place changes to determine if attribute_changed?Sean Griffin2014-12-221-1/+5
| | | | | | | | | Calling `changed_attributes` will ultimately check if every mutable attribute has changed in place. Since this gets called whenever an attribute is assigned, it's extremely slow. Instead, we can avoid this calculation until we actually need it. Fixes #18029
* Fix inaccurate docs in active_model errors [ci skip]Robson Marques2014-12-221-2/+2
| | | | | | | | | | | | | | The default value for the argument `message` in `ActiveModel::Errors#add` has a new behavior since ca99ab2481d44d67bc392d0ec1125ff1439e9f94. Before person.errors.add(:name, nil) # => ["is invalid"] After person.errors.add(:name, nil) # => [nil]

* Add AM test: after/around callback returning falseclaudiob2014-12-141-4/+15
| | | | | | | | | | | This stems from https://github.com/rails/rails/pull/17227#discussion_r21641358 It's simply a clarification of the current behavior by which if an `after_` or `around_` ActiveModel callback returns +false+, then the callback chain **is not halted**. The callback chain in ActiveModel is only halted when a `before_` callback returns `false`.
* Add AM test for after_validation returning falseclaudiob2014-12-141-2/+13
| | | | | | | | This stems from https://github.com/rails/rails/pull/17227#discussion_r21641358 It's simply a clarification of the current behavior by which if an `after_validation` ActiveModel callback returns +false+, then further `after_` callbacks **are not halted**.
* Pass through the `prepend` option to `AS::Callback`Godfrey Chan2014-12-122-2/+38
| | | | | | | | | | | | | I'm not sure what's the use case for this, but apparently it broke some apps. Since it was not the intended result from #16210 I fixed it to not raise an exception anymore. However, I didn't add documentation for it because I don't know if this should be officially supported without knowing how it's meant to be used. In general, validations should be side-effect-free (other than adding to the error message to `@errors`). Order-dependent validations seems like a bad idea. Fixes #18002
* add brackets around attribute_name_tiii2014-12-081-1/+1
| | | | | | since 'attr_name_will_change!' is not an actual method it should be clearer that you have to insert the attribute name as in line 104 [ci skip]
* Correctly handle multiple attribute method prefix/suffixes which matchSean Griffin2014-12-041-6/+4
| | | | | | | | | Active Record defines `attribute_method_suffix :?`. That suffix will match any predicate method when the lookup occurs in Active Model. This will make it incorrectly decide that `id_changed?` should not exist, because it attempts to determine if the attribute `id_changed` is present, rather than `id` with the `_changed?` suffix. Instead, we will look for any correct match.
* Ensure numericality validations work with mutationSean Griffin2014-12-011-0/+11
| | | | | | | | | | | | | | | | | | | | | The detection of in-place changes caused a weird unexpected issue with numericality validations. That validator (out of necessity) works on the `_before_type_cast` version of the attribute, since on an `:integer` type column, a non-numeric string would type cast to 0. However, strings are mutable, and we changed strings to ensure that the post type cast version of the attribute was a different instance than the before type cast version (so the mutation detection can work properly). Even though strings are the only mutable type for which a numericality validation makes sense, special casing strings would feel like a strange change to make here. Instead, we can make the assumption that for all mutable types, we should work on the post-type-cast version of the attribute, since all cases which would return 0 for non-numeric strings are immutable. Fixes #17852

* Bump required Ruby version to 2.1.0claudiob2014-11-281-1/+1
| | | | | | | | | [This article](http://weblog.rubyonrails.org/2014/8/20/Rails-4-2-beta1/#maintenance-consequences-and-rails-5-0) states that: > Rails 5.0 is in most likelihood going to target Ruby 2.2. Before the exact minimum version is fully decided, @arthurnn [suggests](https://github.com/rails/rails/pull/17830#issuecomment-64940383) that **at least** version 2.1.0 **must** be required by the `gemspec` files.

| | | | | | | | | ActiveModel::Dirty#clear_attribute_changes method In Rails 4.2 it is impossible to define a custom default value for a model's attribute without making it appear as _changed?, especially when the model is first initialized. Making this method publicly visible will allow such a behaviour, without the need to use private APIs.

| | | | | | | | | | | | | | | This patch uniformizes warning messages. I used the most common style already present in the code base: * Capitalize the first word. * End the message with a full stop. * "Rails 5" instead of "Rails 5.0". * Backticks for method names and inline code. Also, converted a few long strings into the new heredoc convention.

| | | | | | | | | | | | | | | | | | The documentation on `:on` for validations was inconsistent, and most only referenced the `:create` and `:update` contexts. I fixed those to be consistent with the documentation on `AM::Validations.validates`, which seemed to have the best docs. [ci skip]

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we want this flag to be enabled anytime we are running the tests under JRuby, let's enable this at the Rakefile level so people get the performance boost on their local checkout. Moreover, we avoid having to update this particular line anytime the option changes on the JRuby side. The only drawback is that we have to define it in every Rakefile but there's no big deal, this is already the case for other options.

I measured that using this script: ``` require 'objspace' require 'active_record' require 'allocation_tracer' ActiveRecord::Base.establish_connection adapter: "sqlite3", database: ":memory:" ActiveRecord::Base.connection.instance_eval do create_table(:articles) { |t| t.string :name } end class Article < ActiveRecord::Base; end a = Article.create name: "foo" a = Article.find a.id N = 10 result = ObjectSpace::AllocationTracer.trace do N.times { Article.find a.id } end result.sort.each do |k,v| p k => v end puts "total: #{result.values.map(&:first).inject(:+)}" ``` When I run this against master and this branch I get this output: ``` pete@balloon:~/projects/rails/activerecord$ git checkout master M Gemfile Switched to branch 'master' pete@balloon:~/projects/rails/activerecord$ bundle exec ruby benchmark_allocation_with_callback_send.rb > allocations_before pete@balloon:~/projects/rails/activerecord$ git checkout remove-dynamic-send-on-built-in-callbacks M Gemfile Switched to branch 'remove-dynamic-send-on-built-in-callbacks' pete@balloon:~/projects/rails/activerecord$ bundle exec ruby benchmark_allocation_with_callback_send.rb > allocations_after pete@balloon:~/projects/rails/activerecord$ diff allocations_before allocations_after 39d38 < {["/home/pete/projects/rails/activesupport/lib/active_support/callbacks.rb", 81]=>[40, 0, 0, 0, 0, 0]} 42c41 < total: 630 --- > total: 590 ``` In addition to this, there are two micro-optimizations present: * Using `block.call if block` vs `yield if block_given?` when the block was being captured already. ``` pete@balloon:~/projects$ cat benchmark_block_call_vs_yield.rb require 'benchmark/ips' def block_capture_with_yield &block yield if block_given? end def block_capture_with_call &block block.call if block end def no_block_capture yield if block_given? end Benchmark.ips do |b| b.report("block_capture_with_yield") { block_capture_with_yield } b.report("block_capture_with_call") { block_capture_with_call } b.report("no_block_capture") { no_block_capture } end pete@balloon:~/projects$ ruby benchmark_block_call_vs_yield.rb Calculating ------------------------------------- block_capture_with_yield 124979 i/100ms block_capture_with_call 138340 i/100ms no_block_capture 136827 i/100ms ------------------------------------------------- block_capture_with_yield 5703108.9 (±2.4%) i/s - 28495212 in 4.999368s block_capture_with_call 6840730.5 (±3.6%) i/s - 34169980 in 5.002649s no_block_capture 5821141.4 (±2.8%) i/s - 29144151 in 5.010580s ``` * Defining and calling methods instead of using send. ``` pete@balloon:~/projects$ cat benchmark_method_call_vs_send.rb require 'benchmark/ips' class Foo def tacos nil end end my_foo = Foo.new Benchmark.ips do |b| b.report('send') { my_foo.send('tacos') } b.report('call') { my_foo.tacos } end pete@balloon:~/projects$ ruby benchmark_method_call_vs_send.rb Calculating ------------------------------------- send 97736 i/100ms call 151142 i/100ms ------------------------------------------------- send 2683730.3 (±2.8%) i/s - 13487568 in 5.029763s call 8005963.9 (±2.7%) i/s - 40052630 in 5.006604s ``` The result of this is making typical ActiveRecord operations slightly faster: https://gist.github.com/phiggins/e46e51dcc7edb45b5f98
