from unbuffered (0) to buffering (-1) to match the behavior existing code
expects and match the behavior of the subprocess module in Python 2 to avoid
introducing hard to track down bugs.
tests that depend on filling up an OS pipe so that they work properly
on systems configured with large pipe buffers.
Also a subprocess docstring update that i forgot was in my client when
i did the original 3.3 commit... easier to just leave that in here
with this one than go back and undo/redo.
As stated in PEP 11, 3.4 removes code on Windows platforms where
COMSPEC points to command.com. The w9xpopen project in Visual Studio
was added to support that case, and there was a special case in subprocess
to cover that situation. This change removes the w9xpopen project from
the Visual Studio solution and removes any references to the w9xpopen
executable.

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.
On error, call(), check_call(), check_output() and getstatusoutput() functions
of the subprocess module now kill the process, read its status (to avoid
zombis) and close pipes.
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)
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.
This was the original intention, but it wasn't threaded all the way through due
to 'endtime'. Also added a trivial assertion to get coverage of __str__.
If the timeout expires before the subprocess exits, the wait method and the
communicate method will raise a subprocess.TimeoutExpired exception. When used
with communicate, it is possible to catch the exception, kill the process, and
retry the communicate and receive any output written to stdout or stderr.

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)
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.

subprocess.Popen.__del__ referenced global objects, which is a no-no thanks to
interpreter shutdown semantics. Same issue goes for the methods that __del__
called. Now all the methods capture the global objects it needs as default
values to private parameters (could have stuck them on the class object itself,
but since the objects have nothing directly to do with the class that seemed
wrong).
There is no test as making one that works is hard. This patch was
verified against a consistently failing test in Mercurial's test suite, though,
so it has been tested in some regard.
Closes issue #5099. Thanks to Mary Stern for the bug report and Gabriel
Genellina for writing another patch for the same issue and attempting to write
a test.
