* Fix broken comments indentation caused by rubocop auto-correct [ci skip]Ryuta Kamizono2016-09-141-6/+6
| | | | | | All indentation was normalized by rubocop auto-correct at 80e66cc4d90bf8c15d1a5f6e3152e90147f00772. But comments was still kept absolute position. This commit aligns comments with method definitions for consistency.

| | | | | The current code base is not uniform. After some discussion, we have chosen to go with double quotes by default.
* clarify that helper_method makes both methods available in the viewTony Miller2016-03-071-1/+2
| | | | | It's probably obvious to most, but clarify that `:helper_method` will make both of these methods available to the view.
* 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)

This is wrong because there is a helper file. Missing helper file helpers/my_helper.rb Now when helper try to require non-existed file rails will throw proper exception. No such file to load -- missing

| | | | | | | The `path` method on missing helper errors is inconsistent with the implementation on LoadError in Ruby 2.0. Wrap up the missing helper exceptions so that the inconsistent behavior is mirrored in Ruby 2.0 (until we can figure out *why* it's inconsistent).

| | | | | | | | | | | | | | | | | | | | | | | | flushing due to runtime Kernel#extend: * The helper module adds a new _helper_serial property onto AbstractController subclasses * When #helper is used to add helpers to a class, the serial number is updated * An ActionView subclass is created and cached based on this serial number. * That subclass includes the helper module from the controller * Subsequent requests using the same controller with the same serial will result in reusing that subclass, rather than being forced to take an action (like include or extend) that will result in a global method cache flush on MRI and a flush of the entire AV class' cache on JRuby. * For now, this optimization is not applied to the RJS helpers, which results in a global method cache flush in MRI and a flush of the JavaScriptGenerator class in JRuby only when using RJS. * Since the effects are limited to using RJS, and would only affect JavaScriptGenerator in JRuby (as opposed to the entire view object), it seems worthwhile to apply this now. * This resulted in a significant performance improvement. I will have benchmarks in the next day or two that show the performance impact of the last several commits. * There is a small chance this could break existing code (although I'm not sure how). If that happens, please report it immediately.
