baserubyに1.8.xを指定すると make benchmark がエラー

Added by kosaki (Motohiro KOSAKI) about 13 years ago. Updated over 12 years ago.

Status:
Closed
Target version:
-
ruby -v:
ruby 1.9.3dev (2011-01-28 trunk 30708) [x86_64-linux]
Backport:
[ruby-dev:43143]

Description

=begin
trunkをビルドするとき、baserubyを指定する必要があるのですが、多くの人はruby-1.8.xを
指定していると思います(それが推奨と以前聞きました)。

しかしながら、make benchmarkがbaseruby指定時にbaserubyとビルドしたrubyとの性能比較モードで
動作するため以下のエラーが出ます。


benchmark results:

make: *** [benchmark] Error 1

「Benchmark process exited」と言われてもまったく分からんのですが、
エスパー能力により以下のスクリプトが stack level too deep で異常終了
するのが原因と分かりました。

benchmark/bm_app_factorial.rb

def fact(n)
if(n > 1)
n * fact(n-1)
else
1
end
end

8.times{
fact(5000)
}

  1. benchmarkディレクトリに1.8.xで動作するスクリプトしか置かない
  2. make benchmark のデフォルト動作を変え、baserubyは無視する

の二案あるのですが (2) が現実的だと思います。

Motohiro, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.


  • lib/benchmark.rb: fix benchmarck to work with current ruby.
    patched by Benoit Daloze [ruby-core:33846] [ruby-dev:43143]
    merged from https://github.com/eregon/ruby/commits/benchmark

  • lib/benchmark (Report#width): update documentation
