* Add `Style/RedundantFreeze` to remove redudant `.freeze`Yasuo Honda2018-09-291-8/+8
| | | | | | | | | | | | | | | | | | | | | Since Rails 6.0 will support Ruby 2.4.1 or higher `# frozen_string_literal: true` magic comment is enough to make string object frozen. This magic comment is enabled by `Style/FrozenStringLiteralComment` cop. * Exclude these files not to auto correct false positive `Regexp#freeze` - 'actionpack/lib/action_dispatch/journey/router/utils.rb' - 'activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb' It has been fixed by https://github.com/rubocop-hq/rubocop/pull/6333 Once the newer version of RuboCop released and available at Code Climate these exclude entries should be removed. * Replace `String#freeze` with `String#-@` manually if explicit frozen string objects are required - 'actionpack/test/controller/test_case_test.rb' - 'activemodel/test/cases/type/string_test.rb' - 'activesupport/lib/active_support/core_ext/string/strip.rb' - 'activesupport/test/core_ext/string_ext_test.rb' - 'railties/test/generators/actions_test.rb'
* Enable `Performance/UnfreezeString` copyuuji.yaginuma2018-09-231-3/+3

* Maintain original encoding from patheileencodes2017-05-121-0/+2
| | | | | | | | | When the path info is read from the socket it's encoded as ASCII 8BIT. The unescape method changes the encoding to UTF8 but it should maintain the encoding of the string that's passed in. This causes parameters to be force encoded to UTF8 when we don't actually know what the encoding of the parameter should be.

* 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)
* Use block variable instead of globalschneems2015-06-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | ```ruby require 'benchmark/ips' Benchmark.ips do |x| x.report("$&") { "foo".sub(/f/) { $&.upcase } } x.report("block var") { "foo".sub(/f/) {|match| match.upcase } } end ``` ``` Calculating ------------------------------------- $& 48.658k i/100ms block var 49.666k i/100ms ------------------------------------------------- $& 873.156k (± 9.3%) i/s - 4.331M block var 969.744k (± 9.2%) i/s - 4.818M ``` It's faster, and gets rid of a few "magic" global variables
* Force encoding of US-ASCII to UTF-8 in unescape_uri.Karl Entwistle2014-07-101-5/+7
| | | | | | | | | Because URI paths may contain non US-ASCII characters we need to force the encoding of any unescaped URIs to UTF-8 if they are US-ASCII. This essentially replicates the functionality of the monkey patch to URI.parser.unescape in active_support/core_ext/uri.rb. Fixes #16104.

* Make URL escaping more consistentAndrew White2014-04-201-0/+9
| | | | | | | | | | | | | | | | | | | | | | 1. Escape '%' characters in URLs - only unescaped data should be passed to URL helpers 2. Add an `escape_segment` helper to `Router::Utils` that escapes '/' characters 3. Use `escape_segment` rather than `escape_fragment` in optimized URL generation 4. Use `escape_segment` rather than `escape_path` in URL generation For point 4 there are two exceptions. Firstly, when a route uses wildcard segments (e.g. *foo) then we use `escape_path` as the value may contain '/' characters. This means that wildcard routes can't be optimized. Secondly, if a `:controller` segment is used in the path then this uses `escape_path` as the controller may be namespaced. Fixes #14629, #14636 and #14070.
* Optimize URI escapingAndrew White2014-04-201-17/+42
| | | | | | | | | | | | | The URI::Parser#escape method is a general use method that has to deal with a variety of input however our use of it is limited in scope so we can increase the performance by implementing our specific needs within ActionDispatch::Journey::Router::Utils directly. If there is no encoding required then there is no change in performance or number of objects allocated, but for each character that needs to be encoded we save five object allocations and gain a performance boost. The performance boost seen varies from 20% when there is one character to over 50% when encoding ten characters.
* Always escape string passed to url helper.edogawaconan2014-04-201-1/+1
| | | | | | | | | | Makes it clear that anything passed with the helper must not be percent encoded. Fixes previous behavior which tricks people into believing passing non-percent-encoded will generate a proper percent-encoded path while in reality it doesn't ('%' isn't escaped). The intention is nice but the heuristic is broken.

Move the Journey code underneath the ActionDispatch namespace so that we don't pollute the global namespace with names that may be used for models. Fixes rails/journey#49.
