Python 3.4 includes a range of improvements of the 3.x series, including hundreds of small improvements and bug fixes. Major new features and changes in the 3.4 release series so far include:
- PEP 446, changing file descriptors to not be inherited by default in subprocesses
The title of the PEP is "Make newly created file descriptors non-inheritable". It has an impact on all functions creating files and sockets not only the subprocess module.
I don't think Larry's description is wrong. "Non-inheritable" is a shorthand for "non-inheritable in subprocesses" with "subprocesses" taken in the general sense (i.e. not only created with the subprocess module).
Oh, I misunderstood "in subprocesses", I read "in the subprocess module".
The definition of FD inheritance is tricky. For example, on UNIX "non-inheritable" file descriptors are still inherited at fork :-)
I hope that the documentation is explicit enough: http://docs.python.org/dev/library/os.html#inheritance-of-file-descriptors
