Línea de trabajo

Start with the current implementations of shutil.copy, shutil.copy2, and shutil.copyfile, then review the linked python_shutil_copyfile.diff and python_shutil_copy_with_umask.diff patches. Compare their proposed handling of race conditions and umask-related disclosure with the open issue; done means the security concerns are addressed and the relevant behavior is covered by the project's existing checks.
