| * Fixes Issue #16114: The subprocess module no longer provides aGregory P. Smith2012-10-101-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | misleading error message stating that args[0] did not exist when either the cwd or executable keyword arguments specified a path that did not exist. It now keeps track of if the child got as far as preexec and reports it if not back to the parent via a special "noexec" error message value in the error pipe so that the cwd can be blamed for a failed chdir instead of the exec of the executable being blamed instead. The executable is also always reported accurately when exec fails. Unittests enhanced to cover these cases.

| | | | | | | | | | | | | | | | | | Remove the pure Python POSIX subprocess implementation. If non-CPython VMs (are there any for 3.x yet?) were somehow depending on this, they already have the exact same set of problems with Python code being executed after os.fork() that _posixsubprocess was written to deal with. They should implement an equivalent outside of Python.
