Place breakpoint in file SuperCallAction.cs after the call to method = targetClass.ResolveSuperMethodNoLock(currentMethodName, currentDeclaringModule).InvalidateSitesOnOverride().Info;
this finds the method. You can see that it is a RubyLibraryMethodInfo (i.e. a Ruby method defined in C# library) and has two overloads (MethodBases property) {IronRuby.Builtins.RubyIO Reinitialize(IronRuby.Builtins.RubyIO, Int32, IronRuby.Builtins.MutableString)} {IronRuby.Builtins.RubyIO Reinitialize(IronRuby.Builtins.RubyIO, Int32, Int32)} This method is defined in IOOps and expects the first argument to be a file descriptor. If we look at File's private instance methods in MRI we see: irb(main):004:0> File.private_instance_methods(false).sort => ["initialize"] While in IronRuby we get a different result: >>> File.private_instance_methods(false).sort => ["blockdev?", "chardev?", "directory?", "executable?", "executable_real?", "exist?", "exists?", "file?", "grpowned?", "identical?", "owned?", "pipe?", "readable?", "readable_real?", "setgid?", "setuid?", "size", "size?", "socket?", "stic ky?", "symlink?", "writable?", "writable_real?", "zero?"] This means there are two bugs: 1) initialize is missing from File 2) bunch of private methods shouldn't be there Have a fix almost ready.

Does anyone know where super class ctors are resolved? I haven't been able to spot where they are resolved in the code. -Charles _______________________________________________ Ironruby-core mailing list Ironruby-core@rubyforge.org http://rubyforge.org/mailman/listinfo/ironruby-core _______________________________________________ Ironruby-core mailing list Ironruby-core@rubyforge.org http://rubyforge.org/mailman/listinfo/ironruby-core
