| | | The intention here is to make the required config copy-able from the console/logs, so add a newline at the end of the message to make that easier. (Otherwise it would be `... raise_in_transactional_callbacks = true (called from...`.)

| | | | | For now, we don't want to take "scoping" calls in to account when calculating cache keys for relations, so just opt-out.

| * | Autosave callbacks shouldn't be `after_save`Agis-2014-10-134-1/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 068f092ced8483e557725542dd919ab7c516e567 registered autosave callbacks as `after_save` callbacks. This caused the regression described in #17209. Autosave callbacks should be registered as `after_update` and `after_create` callbacks, just like before. This is a partial revert of 068f092ced8483e557725542dd919ab7c516e567. Fixes #17209.

It will never use nullify or delete_all delete_all's behavior varies greatly based on `hm` vs `hm:t` and deletion strategy.

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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
