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)
* | | | Stop using deprecated `render :text` in testPrem Sichanugrist2015-07-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will silence deprecation warnings. Most of the test can be changed from `render :text` to render `:plain` or `render :body` right away. However, there are some tests that needed to be fixed by hand as they actually assert the default Content-Type returned from `render :body`.

| | | | | | | | | | | | | | | | | | | | | These methods had defined in 2004 by dhh in initial commit and `ActionDispatch::Request` class has been inherited from `Rack::Request` class in 2009 by josh. In 2014 these methods and more of them defined in `Rack::Request` class so we don't need them anymore in rails codebase.

* / Fix method signature of `parse_query` to match rackeileencodes2015-04-061-1/+1
|/ | | | | | | Recently rack was changed to have a second argument on the `parse_query` method (in rack/rack#781). Rails relies on this and it's `parse_query` method was complaining about missing the second argument. I changed the arguments to `*` so we don't have this issue in the future.
* Add ActiveSupport::ArrayInquirer and Array#inquiryGeorge Claghorn2015-03-241-27/+2
| | | | | | | | | | | | | | | | | | | | | | Wrapping an array in an `ArrayInquirer` gives a friendlier way to check its string-like contents. For example, `request.variant` returns an `ArrayInquirer` object. To check a request's variants, you can call: request.variant.phone? request.variant.any?(:phone, :tablet) ...instead of: request.variant.include?(:phone) request.variant.any? { |v| v.in?([:phone, :tablet]) } `Array#inquiry` is a shortcut for wrapping the receiving array in an `ArrayInquirer`: pets = [:cat, :dog] pets.cat? # => true pets.ferret? # => false pets.any?(:cat, :ferret} # => true

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bug caused a segfault and you can find more info about it at: https://bugs.ruby-lang.org/issues/10685. We did a couple of work arounds, but 2.2.1 rolled out and those aren't needed anymore. Here are the reverted commits: - Revert "Work around for upstream Ruby bug #10685", commit 707a433870e9e06af688f85a4aedc64a90791a64. - Revert "Fix segmentation fault in ActionPack tests", commit 22e0a22d5f98e162290d9820891d8191e720ad3b. I'm also bumping the Ruby version check to 2.2.1 to prevent future segfaults.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In f6e293ec54f02f83cdb37502bea117f66f87bcae we avoided a segfault in the tests, however I think we should try to avoid the crash, as it may happen in user code as well. Here is what I distiled the bug down to: ```ruby # Rails case - works on 2.0, 2.1; crashes on 2.2 require 'action_dispatch' ActionDispatch::Response.new(200, "Content-Type" => "text/xml") # General case - works on 2.0, 2.1; crashes on 2.2 def foo(optional = {}, default_argument: nil) end foo('quux' => 'bar') ```
