* Simplify codeMarcin Olichwirowicz2015-08-131-5/+4
| | | | | Since we are always responding with an array and using `any?`, we don't need to check if an array is empty

* deprecate the env method on controller instancesAaron Patterson2015-08-071-1/+1
| | | | | | people should be accessing request information through the request object, not via the env hash. If they really really want at the env hash, then they can get it off the request.
* stop using @_env in the controller instanceAaron Patterson2015-08-071-0/+8
| | | | | | | Actions are processed through `dispatch`, so they should have the request set on them before any user land code can be executed. Lets stop setting _env on the controller, and give access to it through the `env` method.
* refactor param parsing middleware to use request objectsAaron Patterson2015-08-071-0/+8
| | | | | this is another place that we should stop directly accessing the env hash and let the request object take care of that for us

* use a request object to access info from env in GetIpAaron Patterson2015-08-061-1/+7
| | | | | | | again, we want to hide the contents of `env` from the implementation. Allocate a request object to access the contents of env, but save allocations due to string literal allocations when accessing the env hash.
* ask the request if we should show exceptionsAaron Patterson2015-08-061-0/+7
| | | | | hide the env key in the request object so that other code doesn't need to know.

* | Freeze string literals when not mutated.schneems2015-07-192-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)
* | 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`.

* 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') ```
