New submission from Nick Venenga <n...@venenga.com>:
shutil.copy fails to copy a file from a shadow copy back to its original file since os.path.samefile returns True. os.path.samefile doesn't reliably detect these files are different since it relies on ino which is the same for both files >>> sc = >>> pathlib.Path('//?/GLOBALROOT/Device/HarddiskVolumeShadowCopy3/test.file') >>> o = pathlib.Path("V:/test.file") >>> os.path.samefile(sc, o) True >>> os.stat(sc) os.stat_result(st_mode=33206, st_ino=3458764513820579328, st_dev=1792739134, st_nlink=1, st_uid=0, st_gid=0, st_size=1, st_atime=1644973968, st_mtime=1644974052, st_ctime=1644973968) >>> os.stat(o) os.stat_result(st_mode=33206, st_ino=3458764513820579328, st_dev=1792739134, st_nlink=1, st_uid=0, st_gid=0, st_size=2, st_atime=1644973968, st_mtime=1644974300, st_ctime=1644973968) >>> open(sc, "r").read() '1' >>> open(o, "r").read() '12' In the above example, you can see the shadow copy file and the original file. Their mode and ino are the same, but their modified time and contents are different ---------- components: Windows messages: 413307 nosy: nijave, paul.moore, steve.dower, tim.golden, zach.ware priority: normal severity: normal status: open title: os.path.samefile incorrect results for shadow copies type: behavior versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46763> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
