* erb.rb: Use str_uplus instead of rb_str_dupk0kubun2017-05-271-3/+3

* erb.rb: Generate static string with opt_str_uminusk0kubun2017-05-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to skip object allocation for static string. We can't always enable frozen_string_literal pragma because we can't freeze string literals embedded by user for backward compatibility. So we need to use fstring for each static string. Since adding ".freeze" to string literals in #content_dump is slow on compiling, I used unary "-" operator instead. benchmark/bm_app_erb_render.rb: Added rendering-only benchmark to test rendering performance on production environment. This benchmark is created to reproduce the behavior on Sinatra (Tilt). Thus it doesn't use ERB#result to skip parsing compiled code. It doesn't use ERB#def_method too to regard `title` and `content` as local variables. If we use #def_method, `title` and `content` needs to be method call. I wanted to avoid it. This patch's benchmark results is: * Before app_erb_render 1.250 app_erb 0.704 * After app_erb_render 1.066 app_erb 0.686 This patch optimizes rendering performance (app_erb_render) without spoiling (total of rendering +) compiling performance (app_erb). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58905 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* erb.rb: Use script encoding instead of force_encodingk0kubun2017-05-261-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original intention of introducing `_erbout.force_encoding` in r21170 was: - "returns a string in the same character encoding as the input string." - "When the input string has a magic comment, however, it returns a string in the encoding specified by the magic comment." And they are tested by test/erb/test_erb_m17n.rb well and this patch passes the test. Since magic comment is always added in ERB compiled code, using ''.dup instead of String.new will set correct encoding without calling force_encoding method. The benchmark results are: * Before $ ./ruby benchmark/run.rb --matzruby=./ruby -m bm_app_erb MatzRuby: ruby 2.5.0dev (2017-05-26 skip-force-enc.. 58903) [x86_64-linux] last_commit=Skip force_encoding in compiled code of erb Ruby: app_erb: matz 0.715 * After $ ./ruby benchmark/run.rb --matzruby=./ruby -m bm_app_erb MatzRuby: ruby 2.5.0dev (2017-05-26 skip-force-enc.. 58903) [x86_64-linux] last_commit=Skip force_encoding in compiled code of erb Ruby: app_erb: matz 0.672 And perf(1) results are: * Before $ sudo perf stat ./ruby benchmark/bm_app_erb.rb Performance counter stats for './ruby benchmark/bm_app_erb.rb': 709.571746 task-clock (msec) # 1.000 CPUs utilized 5 context-switches # 0.007 K/sec 1 cpu-migrations # 0.001 K/sec 1,337 page-faults # 0.002 M/sec 3,088,936,521 cycles # 4.353 GHz <not supported> stalled-cycles-frontend <not supported> stalled-cycles-backend 4,849,564,282 instructions # 1.57 insns per cycle 1,027,042,087 branches # 1447.411 M/sec 19,983,456 branch-misses # 1.95% of all branches 0.709747823 seconds time elapsed * After $ sudo perf stat ./ruby benchmark/bm_app_erb.rb Performance counter stats for './ruby benchmark/bm_app_erb.rb': 693.494673 task-clock (msec) # 1.000 CPUs utilized 7 context-switches # 0.010 K/sec 1 cpu-migrations # 0.001 K/sec 1,316 page-faults # 0.002 M/sec 3,025,639,349 cycles # 4.363 GHz <not supported> stalled-cycles-frontend <not supported> stalled-cycles-backend 4,694,848,271 instructions # 1.55 insns per cycle 994,496,704 branches # 1434.037 M/sec 19,693,239 branch-misses # 1.98% of all branches 0.693724345 seconds time elapsed [fix GH-1147] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58904 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | | | | | | | | | | | | | | | if stags and etags are not changed from default. :putobject insn (of regexp) will be used instead of :toregexp insn. This means that the regexp won't be compiled for every `SimpleScanner#scan` call. It may not be a good idea to apply this kind of optimization for all cases. But I applied this because it is default scanner and used frequently and has relatively large impact for benchmark like this: * Before app_erb 1.023 * After app_erb 0.781 This commit fixes only the bottleneck of performance regression introduced in r53412. For maintainability, I won't fix other small regressions like additional overhead of method calls.

| | | | | | | | | | | | | | | | | | | * lib/rubygems/test_case.rb (teardown): call `Gem::refresh()` at the end of `teardown`. On parallel test sometimes fails test process. The reason is: (1) previous tests remains `Gem::Specification@@stubs` value which points to temporary directories and the directories are removed by `teardown` method of previous test. (2) `require 'rubygems/gem_runner'` in `test_gem_gem_runner.rb` tries to require test utility file. However, with strange `@@stubs` RubyGems tries to load specification from removed directory. `StubSpecification#to_spec` returns `nil` and error will occur. The solution this patch employs is to refresh all of parameters includes `Gem::Specification@@stubs` by `Gem::refresh()`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58736 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
