[issue30400] Race condition in shutil.copyfile(): source file replaced file during copy

[STINNER Victor]

STINNER Victor <vstinner at redhat.com> added the comment:

Python doesn't use FD of directories by default because it introduces
issues of FD limit with deep directory tree, issue of managing FD lifetime,
etc. That's why some API have one flavor for path and another for FD.
