Gregory P. Smith 5591b02a4c Fixes Issue #16114: The subprocess module no longer provides a
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.

Gregory P. Smith 3905171f1e Fixes issue #15756: subprocess.poll() now properly handles errno.ECHILD
to return a returncode of 0 when the child has already exited or cannot
be waited on.

Antoine Pitrou ab85ff3d1a Issue #12591: Improve support of "universal newlines" in the subprocess
module: the piped streams can now be properly read from or written to.

(this was broken due to the 2.x to 3.x transition; communicate() support
is still sketchy)

Gregory P. Smith f560485388 Get rid of the close_fds DeprecationWarning. Changes the default on a per

Gregory P. Smith d23047b62c issue7213 + issue2320: Cause a DeprecationWarning if the close_fds argument is
not passed to subprocess.Popen as the default value will be changing in a
future Python to the safer and more often desired value of True.

DeprecationWarnings that show up in a lot of existing code are controversial
and have caused pain in the past.  I'd like to leave this on for 3.2 beta1 and
see how things go.  We can remove the warning if it is deemed too noisy during
any betas.  (case study: the md5 and sha module DeprecationWarnings are loathed
around the world as those modules were never going to be removed in 2.x and
2to3 has a fixer for code that uses them)
2010-12-04 09:10:44 +00:00
Brian Curtin 79cdb661f5 Fix #10554. Added context manager support to Popen objects.
Added a few common Popen uses to the tests like we've done for a few other
instances of adding context managers. Eventually the entire test suite
could be converted to use the context manager format.
