Gregory P. Smith a0c9caad66 Fix issue #6973: When we know a subprocess.Popen process has died, do
not allow the send_signal(), terminate(), or kill() methods to do
anything as they could potentially signal a different process.
2015-11-15 18:19:10 -08:00
Gregory P. Smith 6e73000723 Add a subprocess.run() function than returns a CalledProcess instance for a
more consistent API than the existing call* functions.
(enhancement from issue 23342)

Gregory P. Smith cb6fdf2c63 issue10838: Rename the subprocess.mswindows internal global to _mswindows.
It is internal only, not a documented API.

Gregory P. Smith ace55865c5 Addresses Issue #10838: The subprocess now module includes
SubprocessError and TimeoutError in its list of exported names for the
users wild enough to use "from subprocess import *".

MAXFD, mswindows and list2cmdline should be dealt with (renamed or
moved) in separate commits.

Brian Curtin 445ad997ab Fix #14470. Remove w9xpopen per PEP 11.
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

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.

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 59fd1bfcc1 The _posixsubprocess module is now required on POSIX.
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.

Reid Kleckner 2b228f0d9b Include the timeout value in TimeoutExpired.
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__.

Reid Kleckner 31aa7dd141 Add a 'timeout' argument to subprocess.Popen.
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.

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.
