185fd33a17 Issue #23836: Use _Py_write_noraise() to retry on EINTR in child_exec() of 
_posixsubprocess

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.

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

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.

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.

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.

daf455554b Issue #18571: Implementation of the PEP 446: file descriptors and file handles 
are now created non-inheritable; add functions os.get/set_inheritable(),
os.get/set_handle_inheritable() and socket.socket.get/set_inheritable().

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.

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.

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.
