* 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

| | | | | | | | | 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]

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

| | | | | | | | | | | | | | | | | | | | | | This change prevents a certain class of user error which results when mistakenly using the `validate` class method instead of the `validates` class method. Only apply when all arguments are symbols, because some validations use the `validate` method and pass in additional options, namely the `LenghValidator` via the `ActiveMode::Validations::validates_with` method.
