"oops" while rearranging the #defines.

Gregory P. Smith e3f7848bc5 Bugfix for issue #8052 fix on *BSD variants. 
Many lack readdir64, use readdir.  Only use readdir64 on solaris where
it is required to work around a solaris bug.

Gregory P. Smith d635af5a61 Fixes issue #8052: The posix subprocess module's close_fds behavior was 
suboptimal by closing all possible file descriptors rather than just
the open ones in the child process before exec().

It now closes only the open fds when it is possible to safely determine what
those are.

Victor Stinner 5572ba7e15 _posixsubprocess.c: don't redefine _GNU_SOURCE if it's already defined 2011-05-26 14:10:08 +02:00
Gregory P. Smith 9c4f44f70a Fix issue #11432. if the stdin pipe is the same file descriptor as either stdout or stderr 
in the _posixsubprocess C extension module it would unintentionally close the fds and raise
an error.

Gregory P. Smith 8edd99d085 Issue #6559: fix the subprocess.Popen pass_fds implementation. Add a unittest. 
Issue #7213: Change the close_fds default on Windows to better match the new
default on POSIX.  True when possible (False if stdin/stdout/stderr are
supplied).

Update the documentation to reflect all of the above.
 2010-12-14 13:43:30 +00:00
Gregory P. Smith 51ee270876 issue7213: Open the pipes used by subprocesses with the FD_CLOEXEC flag from 
the C code, using pipe2() when available.  Adds unittests for close_fds and
cloexec behaviors.
 2010-12-13 07:59:39 +00:00
Gregory P. Smith d4cc7bf993 issue6559: Adds a pass_fds parameter to subprocess.Popen that allows the caller 
to list exactly which file descriptors should be kept open.

Victor Stinner dcb2403022 Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore, 
you have to convert your bytearray filenames to bytes
 2010-04-22 12:08:36 +00:00
Victor Stinner 0e59cc3fc3 Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for 
the current working directory.

Remove also a trailing space, and replace tabulation indentation by spaces.

Gregory P. Smith 32ec9da166 * Fix a refleak when a preexec_fn was supplied (preexec_fn_args_tuple was not 
being defref'ed).
* Fixes another potential refleak of a reference to the gc
  module in the unlikely odd case where gc module isenabled or disable calls
  fail.
* Adds a unittest for the above case to verify behavior and lack of leaks.
 2010-03-19 16:53:08 +00:00
Gregory P. Smith 68f52178d9 * Fix the refcount leak in _PySequence_BytesToCharpArray from r78946. 
* Also fixes a potential extra DECREF of an arg in the error case within
  _posixsubprocess.fork_exec() by not reusing the process_args variable.
 2010-03-15 06:07:42 +00:00
Gregory P. Smith fb94c5f1e5 * Replaces the internals of the subprocess module from fork through exec on 
POSIX systems with a C extension module.  This is required in order for
  the subprocess module to be made thread safe.

  The pure python implementation is retained so that it can continue to be
  used if for some reason the _posixsubprocess extension module is not
  available.

  The unittest executes tests on both code paths to guarantee compatibility.

* Moves PyLong_FromPid and PyLong_AsPid from posixmodule.c into longobject.h.
