Gregory P. Smith 163468a766 bpo-16500: Don't use string constants for os.register_at_fork() behavior (#1834)
Instead use keyword only arguments to os.register_at_fork for each of the scenarios.
Updates the documentation for clarity.

Gregory P. Smith d0a5b1c343 Fixes #23564: Fix a partially broken sanity check in the _posixsubprocess
internals regarding how fds_to_pass were passed to the child.  The bug
had no actual impact as subprocess.py already avoided it.

Victor Stinner 160e819a1d Issue #23694: Fix usage of _Py_open() in the _posixsubprocess module
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.

Victor Stinner a555cfcb73 Issue #23694: Enhance _Py_open(), it now raises exceptions
* _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

Victor Stinner 8f437aac06 Issue #22290: Fix error handling in the _posixsubprocess module.
* 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.

Gregory P. Smith a26987a0a5 Fix the comment to not refer to the removed end_fd parameter. 2014-06-01 13:46:36 -07:00
Gregory P. Smith d4dcb70287 Don't restrict ourselves to a "max" fd when closing fds before exec()
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.

Gregory P. Smith efeb9da4ae Add conditional code for android's lack of definition of SYS_getdent64.
Fixes issue20307.  No Misc/NEWS entry because frankly this is an
esoteric platform for anyone to be figuring out how to cross compile
CPython for.

Gregory P. Smith a10ddb8a55 Fixes Issue #16114: The subprocess module no longer provides a
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.

Gregory P. Smith 5591b02a4c Fixes Issue #16114: The subprocess module no longer provides a
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.
