* Replace (slower) block.call with (faster) yieldclaudiob2014-10-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Performance optimization: `yield` with an implicit `block` is faster than `block.call`. See http://youtu.be/fGFM_UrSp70?t=10m35s and the following benchmark: ```ruby require 'benchmark/ips' def fast yield end def slow(&block) block.call end Benchmark.ips do |x| x.report('fast') { fast{} } x.report('slow') { slow{} } end # => fast 154095 i/100ms # => slow 71454 i/100ms # => # => fast 7511067.8 (±5.0%) i/s - 37445085 in 4.999660s # => slow 1227576.9 (±6.8%) i/s - 6145044 in 5.028356s ```
* Add necessary 'require reverse_merge' to HAWI.rbclaudiob2014-10-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hashes with indifferent access should support `reverse_merge` out-of-the-box but they don't; for instance the following code fails: ```ruby require 'active_support' require 'active_support/hash_with_indifferent_access' hash = HashWithIndifferentAccess.new key: :old_value hash.reverse_merge key: :new_value ``` This PR fixes the case above by simply requiring `active_support/core_ext/hash/reverse_merge` in `hash_with_indifferent_access.rb` and adding a test that confirms the fix. --- Here are more details about the bugfix. Currently, `reverse_merge` is [defined in HashWithIndifferentAccess](https://github.com/rails/rails/blob/4e8ea13ba1a0870905a46fac5f232d9f41eef8a4/activesupport/lib/active_support/hash_with_indifferent_access.rb#L208) by invoking `super`, that is by invoking `Hash#reverse_merge`: ```ruby def reverse_merge(other_hash) super(self.class.new_from_hash_copying_default(other_hash)) end ``` However, Ruby's `Hash` does not have the `reverse_merge` by default: it must be added by ActiveSupport, and that requires the following line of code to be present: ```ruby require 'active_support/core_ext/hash/reverse_merge' ```

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I suspect that positive lookbehind would have been used in the original implementation had it been available in supported Ruby versions at the time. Now that Rails requires Ruby 1.9.2 or above, this is no longer an issue. This fixes #14146 for acronyms such as APIRESTful. This technique also addresses namespaced acronyms that are not entirely uppercased. This was broken when the commit was originally written but has since been fixed in ccbb481. The latter does not deal with adjacent acronyms so this commit wins.

* Reduce allocations when running AR callbacks.Pete Higgins2014-09-281-6/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inspired by @tenderlove's work in c363fff29f060e6a2effe1e4bb2c4dd4cd805d6e, this reduces the number of strings allocated when running callbacks for ActiveRecord instances. 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

| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the following returns `false`, contrary to expectation: 1.minute.eql?(1.minute) Adding method `#eql?` will make this behave like expected. Method `#eql?` is just a bit stricter than `#==`, as it checks whether the argument is also a uration. Their parts may be different though. 1.minute.eql?(60.seconds) # => true 1.minute.eql?(60) # => false

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since Duration is extending from ProxyObject which extends itself from BasicObject, the Duration object doesn't respond to the #instance_of? method. Thus, the #method_missing hook get triggered, delegating the method to its `value` attribute. However, Rubinius' #eql? definition relies on #instance_of?, thus this will equal to true with a Fixnum (since its `value` attribute is a Fixnum) while it should not. The previous behavior was wrong anyway, no matter the implementation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Zero has one digit, but Math.log10(0) returns -Infinity. The method needs to special-case zero. The patch adds a regression test that is not clearly related to the underlying issue because digit_count is private and has no coverage. Gray area. This bug was uncovered by 60062cf.
