* Issue #25764: Merge subprocess fix from 3.4 into 3.5Martin Panter2015-12-051-17/+18

| * Issue #25764: Preserve subprocess fork exception when preexec_fn usedMartin Panter2015-11-301-17/+18
| | | | | | | | Also fix handling of failure to release the import lock.
* | Fixes #23564: Fix a partially broken sanity check in the _posixsubprocessGregory P. Smith2015-11-161-1/+2
| | | | | | | | | | internals regarding how fds_to_pass were passed to the child. The bug had no actual impact as subprocess.py already avoided it.

* | Issue #23694: Fix usage of _Py_open() in the _posixsubprocess moduleVictor Stinner2015-03-301-2/+1
| | | | | | | | | | | | | | Don't call _Py_open() from _close_open_fds_safe() because it is call just after fork(). It's not good to play with locks (the GIL) between fork() and exec(). Use instead _Py_open_noraise() which doesn't touch to the GIL.
* | Issue #23694: Enhance _Py_open(), it now raises exceptionsVictor Stinner2015-03-171-0/+1
|/ | | | | | | | * _Py_open() now raises exceptions on error. If open() fails, it raises an OSError with the filename. * _Py_open() now releases the GIL while calling open() * Add _Py_open_noraise() when _Py_open() cannot be used because the GIL is not held
* Issue #22290: Fix error handling in the _posixsubprocess module.Victor Stinner2014-10-051-6/+14
| | | | | | | | * Don't call the garbage collector with an exception set: it causes an assertion to fail in debug mode. * Enhance also error handling if allocating an array for the executable list failed. * Add an unit test for 4 different errors in the _posixsubprocess module.
* Fix the comment to not refer to the removed end_fd parameter.Gregory P. Smith2014-06-011-2/+2

* Don't restrict ourselves to a "max" fd when closing fds before exec()Gregory P. Smith2014-06-011-43/+44
| | | | | | | | | when we have a way to get an actual list of all open fds from the OS. Fixes issue #21618: The subprocess module would ignore fds that were inherited by the calling process and already higher than POSIX resource limits would otherwise allow. On systems with a functioning /proc/self/fd or /dev/fd interface the max is now ignored and all fds are closed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
