| * Freeze string literals when not mutated.schneems2015-07-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)

| | | | | | | | | | | | | | | | | | When executing an `ActionController::Parameters#fetch` with a block that raises a `KeyError` the raised `KeyError` will be rescued and converted to an `ActionController::ParameterMissing` exception, covering up the original exception.

* Stop using deprecated `render :text` in testPrem Sichanugrist2015-07-173-6/+6
| | | | | | | | | 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`.

| * Add deprecation warning for `render :text`Prem Sichanugrist2015-07-171-0/+14
| | | | | | | | | | | | We've started on discouraging the usage of `render :text` in #12374. This is a follow-up commit to make sure that we print out the deprecation warning.
* | push fields_for_style? in to a protected methodAaron Patterson2015-07-171-5/+5
| | | | | | | | | | this way we don't need to call `to_unsafe_h` to get access to ask questions about the underlying hash
* | push is_a checks up the stackAaron Patterson2015-07-171-13/+13
| | | | | | | | now `hash_filter` doesn't need to know about the `Parameters` class
* | remove useless conditionalAaron Patterson2015-07-171-1/+0
| | | | | | | | | | Since we proved that `element` is always of type `Parameter`, we know that it will always respond to `permit`, so lets remove this conditional
* | remove useless conditionalsAaron Patterson2015-07-171-2/+2
| | | | | | | | | | | | | | | | `element` can never be a hash because: 1. `slice` returns a Parameters object and calls each on it: https://github.com/rails/rails/blob/cb3f25593b1137e344086364d4b1a52c08e8eb3b/actionpack/lib/action_controller/metal/strong_parameters.rb#L656 2. `each` which is implemented by `each_pair` will call `convert_hashes_to_parameters` on the value: https://github.com/rails/rails/blob/cb3f25593b1137e344086364d4b1a52c08e8eb3b/actionpack/lib/action_controller/metal/strong_parameters.rb#L192-197 3. `convert_hashes_to_parameters` will convert any hash objects in to parameters objects: https://github.com/rails/rails/blob/cb3f25593b1137e344086364d4b1a52c08e8eb3b/actionpack/lib/action_controller/metal/strong_parameters.rb#L550-566
* | remove useless functionAaron Patterson2015-07-171-8/+2
| | | | | | | | | | | | Now that the value is cached on the stack, `array_of_permitted_scalars_filter` is exactly the same as `array_of_permitted_scalars?`, so lets just have one
* | stop passing `params` to `array_of_permitted_scalars_filter`Aaron Patterson2015-07-171-4/+6
| | | | | | | | | | | | this way the method doesn't have to know what the new params object is, it just yields to a block. This change also caches the value of `self[key]` on the stack
* | push key checking upAaron Patterson2015-07-171-1/+2
|/ | | | | | We should disconnect `array_of_permitted_scalars_filter` from the instance so that we can make hash filtering functional. For now, pull the conditional up out of that method
* Standardize `ActionController::Parameters#to_unsafe_h` return valueZoltan Kiss2015-07-151-1/+1
| | | | | | `ActionController::Parameters#to_h` returns a hash, so lets have `ActionController::Parameters#to_unsafe_h` return a hash instead of an `ActiveSupport::HashWithIndifferentAccess` for consistency.

* Make AC::Parameters not inherited from HashPrem Sichanugrist2015-07-151-28/+99
| | | | | | | | This is another take at #14384 as we decided to wait until `master` is targeting Rails 5.0. This commit is implementation-complete, as it guarantees that all the public methods on the hash-inherited Parameters are still working (based on test case). We can decide to follow-up later if we want to remove some methods out from Parameters.

|\ | | | | Allow default_render to take a block to customize behavior when there's no template
| * Override default_render's behavior with a blockDave Copeland2015-06-201-2/+17
| | | | | | | | | | | | | | | | | | | | In 0de4a23 the behavior when there is a missing template was changed to not raise an error, but instead head :no_content. This is a breaking change and some gems rely on this happening. To allow gems and other code to work around this, allow `default_render` to take a block which, if provided, will execute the contents of that block instead of doing the `head :no_content`.
