* Add `Style/RedundantFreeze` to remove redudant `.freeze`Yasuo Honda2018-09-291-1/+1
| | | | | | | | | | | | | | | | | | | | | Since Rails 6.0 will support Ruby 2.4.1 or higher `# frozen_string_literal: true` magic comment is enough to make string object frozen. This magic comment is enabled by `Style/FrozenStringLiteralComment` cop. * Exclude these files not to auto correct false positive `Regexp#freeze` - 'actionpack/lib/action_dispatch/journey/router/utils.rb' - 'activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb' It has been fixed by https://github.com/rubocop-hq/rubocop/pull/6333 Once the newer version of RuboCop released and available at Code Climate these exclude entries should be removed. * Replace `String#freeze` with `String#-@` manually if explicit frozen string objects are required - 'actionpack/test/controller/test_case_test.rb' - 'activemodel/test/cases/type/string_test.rb' - 'activesupport/lib/active_support/core_ext/string/strip.rb' - 'activesupport/test/core_ext/string_ext_test.rb' - 'railties/test/generators/actions_test.rb'

* Freeze string literals when not mutated.schneems2015-07-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I wrote a utility that helps find areas where you could optimize your program using a frozen string instead of a string literal, it's called [let_it_go](https://github.com/schneems/let_it_go). After going through the output and adding `.freeze` I was able to eliminate the creation of 1,114 string objects on EVERY request to [codetriage](codetriage.com). How does this impact execution? To look at memory: ```ruby require 'get_process_mem' mem = GetProcessMem.new GC.start GC.disable 1_114.times { " " } before = mem.mb after = mem.mb GC.enable puts "Diff: #{after - before} mb" ``` Creating 1,114 string objects results in `Diff: 0.03125 mb` of RAM allocated on every request. Or 1mb every 32 requests. To look at raw speed: ```ruby require 'benchmark/ips' number_of_objects_reduced = 1_114 Benchmark.ips do |x| x.report("freeze") { number_of_objects_reduced.times { " ".freeze } } x.report("no-freeze") { number_of_objects_reduced.times { " " } } end ``` We get the results ``` Calculating ------------------------------------- freeze 1.428k i/100ms no-freeze 609.000 i/100ms ------------------------------------------------- freeze 14.363k (± 8.5%) i/s - 71.400k no-freeze 6.084k (± 8.1%) i/s - 30.450k ``` Now we can do some maths: ```ruby ips = 6_226k # iterations / 1 second call_time_before = 1.0 / ips # seconds per iteration ips = 15_254 # iterations / 1 second call_time_after = 1.0 / ips # seconds per iteration diff = call_time_before - call_time_after number_of_objects_reduced * diff * 100 # => 0.4530373333993266 miliseconds saved per request ``` So we're shaving off 1 second of execution time for every 220 requests. Is this going to be an insane speed boost to any Rails app: nope. Should we merge it: yep. p.s. If you know of a method call that doesn't modify a string input such as [String#gsub](https://github.com/schneems/let_it_go/blob/b0e2da69f0cca87ab581022baa43291cdf48638c/lib/let_it_go/core_ext/string.rb#L37) please [give me a pull request to the appropriate file](https://github.com/schneems/let_it_go/blob/b0e2da69f0cca87ab581022baa43291cdf48638c/lib/let_it_go/core_ext/string.rb#L37), or open an issue in LetItGo so we can track and freeze more strings. Keep those strings Frozen ![](https://www.dropbox.com/s/z4dj9fdsv213r4v/let-it-go.gif?dl=1)
* Add a note on custom validation contexts.Justin Weiss2014-08-051-3/+5
| | | | | | | | | 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]

* Don't enable validations when passing false hash values to ActiveModel.validatesSteve Purcell2012-05-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Passing a falsey option value for a validator currently causes that validator to be enabled, just like "true": ActiveModel.validates :foo, :presence => false This is rather counterintuitive, and makes it inconvenient to wrap `validates` in methods which may conditionally enable different validators. As an example, one is currently forced to write: def has_slug(source_field, options={:unique => true}) slugger = Proc.new { |r| r[:slug] = self.class.sluggify(r[source_field]) if r[:slug].blank? } before_validation slugger validations = { :presence => true, :slug => true } if options[:unique] validations[:uniqueness] = true end validates :slug, validations end because the following reasonable-looking alternative fails to work as expected: def has_slug(source_field, options={:unique => true}) slugger = Proc.new { |r| r[:slug] = self.class.sluggify(r[source_field]) if r[:slug].blank? } before_validation slugger validates :slug, :presence => true, :slug => true, :uniqueness => options[:unique] end (This commit includes a test, and all activemodel and activerecord tests pass as before.)
