New submission from cagney <[email protected]>:
When O_CLOEXEC is defined the file is opened with that flag (YA! - this means
that the operation is atomic and, by default, the FD will be closed across
os.posix_spawn()).
However the code then goes on an executes:
#ifndef MS_WINDOWS
if (_Py_set_inheritable(fd, 0, atomic_flag_works) < 0) {
close(fd);
return -1;
}
#endif
should this also be #ifndef O_CLOEXEC?
