StringReader defines dispose(bool disposing) and inherits dispose() from 
TextReader.  So it’s either that dispose(bool) is completely hiding the 
inherited dispose or the overload resolution is completely broken – probably 
the former.  It’s probably related to exposing protected members to everyone or 
just some bug in filtering protected members out.

Subject: Re: [Ironruby-core] SVN r114 is out

What could be wrong here?

  def using(o)
    begin
      yield if block_given?
    ensure
      o.dispose
    end
  end

This code worked until rev.113 but now it tells me :

>>> $sr = StringReader.new('Hello, world')
=> #<System::IO::StringReader:0x0000060>
>>> $sr.dispose
:0:in `Initialize': wrong number or type of arguments for `dispose' 
(ArgumentError)

Thanks

This update contains the code we demo'd at RailsConf, and a few improvements 
that we've made since then.



If you rake compile this build, it will generate an ir.cmd file for you in the 
build\debug directory. The rakefile now looks for your MRI install (by 
searching your PATH for ruby.exe). If you have your build\debug directory on 
your path, this file will run correctly.



You will see a bunch of warnings when compiling. We know about these, and will 
fix them soon (it's the DLR folks deprecating a bunch of old APIs).



I've also added a RubyTestKey.snk file which contains a public key. Our 
assemblies are delay-signed using this key, and you must enable skip 
verification to run the assemblies on your dev machine. You'll need to run the 
runfirst.cmd file in svn\trunk to turn on skip verification for assemblies 
signed using our public key.



This should simplify some of the SIGN flag problems, although it introduces a 
new set of problems around signing if you want to distribute the signed 
assemblies. Unfortunately, we had to enable signing on external builds because 
there's some bug that only occurs when running an unsigned build. We're 
investigating this now.



Thanks,

-John
