Martin Panter 528619b6c3 Issue #26782: Add STARTUPINFO to subprocess.__all__ on Windows 2016-04-16 23:42:37 +00:00
Victor Stinner 9def284387 subprocess._optim_args_from_interpreter_flags() 
Issue #26100:

* Add subprocess._optim_args_from_interpreter_flags()
* Add test.support.optim_args_from_interpreter_flags()
* Use new functions in distutils, test_cmd_line_script, test_compileall and
  test_inspect

The change enables test_details() test of test_inspect when -O or -OO command
line option is used.

Gregory P. Smith 6edadfc9ca * Re-fix issue #19284: Don't generate the no-op -R command line 
parameter to "enable" the always on sys.flags.hash_randomization
  in _args_from_interpreter_flags() used by multiprocessing and
  some unittests.  This simplifies the code.
* assert_python_ok docstring typo fix.
* Fix test_cmd_line not to fail if PYTHONHASHSEED is set to a fixed seed.

Gregory P. Smith 2cd1b3b089 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.

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.
 2015-04-07 16:11:33 -07:00
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.
