Subject: [ruby-dev:46740] [ruby-trunk - Bug #7344] gem pristine bigdecimal が失敗してしまう


Issue #7344 has been updated by drbrain (Eric Hodel).


=begin
I think I understand the comments on this bug thanks to google translate but please inform me of anything important I did not address.

Using recent ruby and rubygems:

  $ gem20 env
  RubyGems Environment:
    - RUBYGEMS VERSION: 2.0.0.preview2.1
    - RUBY VERSION: 2.0.0 (2012-12-15 patchlevel -1) [x86_64-darwin12.2.1]
    - INSTALLATION DIRECTORY: /usr/local/lib/ruby/gems/2.0.0
    - RUBY EXECUTABLE: /usr/local/bin/ruby20
    - EXECUTABLE DIRECTORY: /usr/local/bin
    - RUBYGEMS PLATFORMS:
      - ruby
      - x86_64-darwin-12
    - GEM PATHS:
       - /usr/local/lib/ruby/gems/2.0.0
       - /Users/drbrain/.gem/ruby/2.0.0
    - GEM CONFIGURATION:
       - :update_sources => true
       - :verbose => true
       - :backtrace => false
       - :bulk_threshold => 1000
       - :benchmark => false
       - "gemcutter_key" => "********************************"
       - "install" => "--format-executable --no-user-install"
       - "update" => "--format-executable --no-user-install"
       - "uninstall" => "--format-executable --no-user-install"
    - REMOTE SOURCES:
       - http://rubygems.org/

I can pristine big decimal (like hsbt):

  $ gem20 pristine bigdecimal
  Restoring gems to pristine condition...
  Skipped bigdecimal-1.1.0, it is a default gem

and ((%gem pristine --all%)) works:

  $ sudo gem20 pristine --all
  Password:
  Restoring gems to pristine condition…
  […]
  Skipped bigdecimal-1.1.0, it is a default gem
  […]

I can install bigdecimal:

  $ gem20 install bigdecimal
  Building native extensions.  This could take a while...
  Successfully installed bigdecimal-1.1.0
  Parsing documentation for bigdecimal-1.1.0
  Done installing documentation for bigdecimal (1 sec).
  1 gem installed

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?

You also can't uninstall the duplicate version you installed, this is a bug:

  $ gem20 uninstall bigdecimal
  ERROR:  While executing gem ... (Gem::InstallError)
      gem "bigdecimal" cannot be uninstalled because it is a default gem

I will fix this bug ^

NOTE: RubyGems will build bigdecimal.so then install bigdecimal.so and ext/bigdecimal/lib/ into lib/.  RubyGems edits the Makefile so ((%make install%)) will copy the files:

https://github.com/rubygems/rubygems/blob/master/lib/rubygems/ext/builder.rb#L19-L23

So source/build directories and lib directories can be separate (but not source, build and lib).

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。

% gem pristine bigdecimal
Restoring gems to pristine condition...

make: *** [install-so] Error 1

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。
