* Freeze string literals when not mutated.schneems2015-07-193-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)

* Removes unnecessary comments from i18n validations tests [ci skip]Zamith2015-07-111-61/+2
| | | | | | These comments do not add a lot to the readability, grepability or overall understanding of the tests, therefore I believe they can be safely removed.

| | | | | | | | | | Only one constraint option can be used at a time (except for the minimum and maximum ones that can eventually be combined). However, other options can be used with them (e.g. the validation failure message). So let's make the distinction between these two different options categories.

| | | | | | | | | | This adds a script `bin/test` to most Rails framework components. The script uses the rails minitest plugin to augment the runner. See https://github.com/rails/rails/pull/19571 for details about the plugin. I did not yet add `bin/test` for activerecord, activejob and railties. These components rely on specific setup performed in the rake-tasks.

* | [ci skip] Don’t encourage `sudo gem install`claudiob2015-05-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | I think we are better off leaving `sudo` outside of the documented way of installing gems (`activerecord`, `actionpack`, …). We don’t want newbies to think that `sudo` is required or, even worse, than they actually have to type `[sudo] gem install`. In most scenarios, `sudo` is not needed to install gems, and people who do need it, probably already know about it. What do you think? :grin:
