[Win32utils-devel] [ win32utils-Bugs-26988 ] Process.create needs to explicitly make individual handles inheritable
Bugs item #26988, was opened at 2009-08-24 14:01 You can respond by visiting: http://rubyforge.org/tracker/?func=detail&atid=411&aid=26988&group_id=85 Category: win32-process Group: Code Status: Open Resolution: None Priority: 3 Submitted By: Michael Buselli (cosine) Assigned to: Nobody (None) Summary: Process.create needs to explicitly make individual handles inheritable Initial Comment: I''ve encountered some versions of Ruby on Windows (in my particular case Ruby 1.9.1 compiled with MinGW) where IO.pipe does not create inheritable handles. This causes problems when Process.create is used to create a pipe to a child process. The attached patch to win32-process works around this issue by always explicitly calling SetHandleInformation to make the passed handles inheritable. ---------------------------------------------------------------------- You can respond by visiting: http://rubyforge.org/tracker/?func=detail&atid=411&aid=26988&group_id=85

If the present software is helpful enough to add options it knows you need?which is why we have high-level functions like Process.create?it ought to make sure the objects are in the right state for you (i.e. inheritable), too. Thanks! ---------------------------------------------------------------------- Comment By: Daniel Berger (djberg96) Date: 2009-08-30 21:23 Message: Hi, Can''t you just explicitly set the :process_inherit option to true and get the same effect?
