Create new functions for setting handle inheritable flag

[dustymabe]

I've found a case where it would be useful to mark windows file handles as inheritable or not inheritable in a process. In win32-process the SetHandleInformation function is a private function and is not supposed to be accessed outside of the class. It would be generally useful to have this functionality exposed so that users of win32-process could set this information on file handles.

Here is a commit where I accessed the private methods of the win32-process module in order to achieve the desired effect: dustymabe/vagrant-sshfs@6f285cd

In this commit I expose a few higher level functions that will allow users to easily set the inheritable flag for a handle. You can see how one would use these functions in the following commit which is the diff I would make to the code to go from my previous (hacky) implementation to the new one: dustymabe/vagrant-sshfs@78e942d

Would it be reasonable to expose these functions to the users?

Let me think about this. My initial reaction is that this should go into win32-file if anywhere.

Thanks!

I didn't know about win32-file before. I was just following what was already being done in win32-process to set the filehandles to be inheritable. In the case of win32-file, would win32-file have this functionality and then in the future win32-process would depend on win32-file in order to use it?

@dustymabe That's the preliminary idea. I'll probably let this stew for a bit, though.

[dustymabe]

hey @djberg96 any update?

[djberg96]

@dustymabe None, I'm afraid. I've actually been looking for people to take over maintenance of my win32* libraries because I just don't need them any more, and I haven't been dedicating the time that I should to them.

[dustymabe]

Thanks for the candid response. I wish ruby itself would pick up proper support for this in the language so it wasn't required for it to be maintained outside of the main packages. I have a solution that works so don't worry about this for now.

@dustymabe just a quick update that the chef folks are now maintaining the win32 stuff.

[dustymabe]

thanks! are they keeping it in this repo?

[djberg96]

@dustymabe Yep, this is the right place.
