Subject: [ruby-dev:46760] [ruby-trunk - Bug #7344] gem pristine bigdecimal が失敗してしまう


Issue #7344 has been updated by kou (Kouhei Sutou).


> The installed version of bigdecimal and the default gem version are the same, so the installed version can't be used:
>
> $ ruby20 -rbigdecimal -e 'p $".grep(/bigdecimal/)'
> ["/usr/local/lib/ruby/2.0.0/x86_64-darwin12.2.1/bigdecimal.bundle"]
>
> I don't know if this is a bug in RubyGems or not. kou, can you comment?

Umm... It is difficult... OK. It's a bug in RubyGems. We can fix it by the following change:

I think that install command on Mac OS X doesn't report error for the same source and destination file. Could you try the following commands?

  % touch a
  % install a a
  % echo $?

Here is the result on my Debian GNU/Linux:

  % touch a
  % install a a
  install: 'a' and 'a' are the same file
  % echo $?
  1

I think that install on Mac OS X returns 0 for "echo $?".

gem pristine bigdecimal を実行すると以下のエラーが発生して落ちてしまいます。

単独で実行している時は影響がないのですが、 OS アップデート時などに gem pristine --all を実行した時は b で必ず止まってしまうので困っています。
