* code gardening: removes redundant selfsXavier Noria2016-08-081-1/+1
| | | | | | | | | A few have been left for aesthetic reasons, but have made a pass and removed most of them. Note that if the method `foo` returns an array, `foo << 1` is a regular push, nothing to do with assignments, so no self required.

| | | | | The current code base is not uniform. After some discussion, we have chosen to go with double quotes by default.

| | | | | All of this is `nodoc`'ed, so we shouldn't have to worry about breaking changes, if there are any -- all internal API :).
* Lock down new `ImplicitRender` behavior for 5.0 RCGodfrey Chan2016-02-251-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Conceptually revert #20276 The feature was implemented for the `responders` gem. In the end, they did not need that feature, and have found a better fix (see plataformatec/responders#131). `ImplicitRender` is the place where Rails specifies our default policies for the case where the user did not explicitly tell us what to render, essentially describing a set of heuristics. If the gem (or the user) knows exactly what they want, they could just perform the correct `render` to avoid falling through to here, as `responders` did (the user called `respond_with`). Reverting the patch allows us to avoid exploding the complexity and defining “the fallback for a fallback” policies. 2. `respond_to` and templates are considered exhaustive enumerations If the user specified a list of formats/variants in a `respond_to` block, anything that is not explicitly included should result in an `UnknownFormat` error (which is then caught upstream to mean “406 Not Acceptable” by default). This is already how it works before this commit. Same goes for templates – if the user defined a set of templates (usually in the file system), that set is now considered exhaustive, which means that “missing” templates are considered `UnknownFormat` errors (406). 3. To keep API endpoints simple, the implicit render behavior for actions with no templates defined at all (regardless of formats, locales, variants, etc) are defaulted to “204 No Content”. This is a strictly narrower version of the feature landed in #19036 and #19377. 4. To avoid confusion when interacting in the browser, these actions will raise an `UnknownFormat` error for “interactive” requests instead. (The precise definition of “interactive” requests might change – the spirit here is to give helpful messages and avoid confusions.) Closes #20666, #23062, #23077, #23564 [Godfrey Chan, Jon Moss, Kasper Timm Hansen, Mike Clark, Matthew Draper]

* move digest cache on to the DetailsKey objectAaron Patterson2016-02-181-0/+16
| | | | | | | | | | | | | This moves digest calculation cache on to the details key object. Before, the digest cache was a class level ivar, and one of the keys was the hash value of the details key object: https://github.com/rails/rails/blob/13c4cc3b5aea02716b7459c0da641438077f5236/actionview/lib/action_view/digestor.rb#L28 An object's hash value is not unique, so it's possible for this cache key to produce colliding keys with no resolution. This commit move cache on to the details key object itself, so we know that the digests are always unique per details key object.

* Freeze string literals when not mutated.schneems2015-07-191-3/+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)

* Template lookup now respect default locale and I18n fallbacks.Rafael Mendonça França2014-12-291-8/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Given the following templates: mailer/demo.html.erb mailer/demo.en.html.erb mailer/demo.pt.html.erb Before this change for a locale that doesn't have its related file the `mailer/demo.html.erb` will be rendered even if `en` is the default locale. Now `mailer/demo.en.html.erb` has precedence over the file without locale. Also, it is possible to give a fallback. mailer/demo.pt.html.erb mailer/demo.pt-BR.html.erb So if the locale is `pt-PT`, `mailer/demo.pt.html.erb` will be rendered given the right I18n fallback configuration. Fixes #11884.

* remove Set.new from DetailsKey::get, impacts rendering overhead performanceLuke Gruber2014-06-251-1/+1
| | | | | | | | | Using ruby-prof, I noticed that Set#add had the largest 'self time' percentage (5% of the overall time spent rendering) when benchmarking the rendering of a small cached ERB template that was 3 lines long. It turns out it was from this line. I don't believe the Set is necessary, either. Removing this line increases the rendering ips using Benchmark::ips accordingly.

* Action Pack VariantsŁukasz Strzałkowski2013-12-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default, variants in the templates will be picked up if a variant is set and there's a match. The format will be: app/views/projects/show.html.erb app/views/projects/show.html+tablet.erb app/views/projects/show.html+phone.erb If request.variant = :tablet is set, we'll automatically be rendering the html+tablet template. In the controller, we can also tailer to the variants with this syntax: class ProjectsController < ActionController::Base def show respond_to do |format| format.html do |html| @stars = @project.stars html.tablet { @notifications = @project.notifications } html.phone { @chat_heads = @project.chat_heads } end format.js format.atom end end end The variant itself is nil by default, but can be set in before filters, like so: class ApplicationController < ActionController::Base before_action do if request.user_agent =~ /iPad/ request.variant = :tablet end end end This is modeled loosely on custom mime types, but it's specifically not intended to be used together. If you're going to make a custom mime type, you don't need a variant. Variants are for variations on a single mime types.
