New submission from Jason R. Coombs <jar...@jaraco.com>:
In https://github.com/jaraco/path/issues/186, the Path project discovered a regression with Python 3.8. It seems that if one creates a symlink with an absolute path. I used `shutil.copytree('temp', 'temp2', True)` and it produced this result: ``` ~ # dir temp Volume in drive C has no label. Volume Serial Number is B8F4-40BB Directory of C:\Users\jaraco\temp 2020-05-16 11:05 PM <DIR> . 2020-05-16 11:05 PM <DIR> .. 2020-05-16 11:05 PM <SYMLINK> bar [c:\Users\jaraco\temp\foo] 2020-05-16 11:04 PM 0 foo 2 File(s) 0 bytes 2 Dir(s) 17,495,805,952 bytes free ~ # dir temp2 Volume in drive C has no label. Volume Serial Number is B8F4-40BB Directory of C:\Users\jaraco\temp2 2020-05-16 11:05 PM <DIR> . 2020-05-16 11:05 PM <DIR> .. 2020-05-16 11:06 PM <SYMLINK> bar [\\?\c:\Users\jaraco\temp\foo] 2020-05-16 11:04 PM 0 foo 2 File(s) 0 bytes 2 Dir(s) 17,495,846,912 bytes free ``` As you can see, in the copy, bar has an additional `\\?\` prefix on the symlink path. On Python 3.7 and earlier, the copy was made without mutating the metadata. ---------- components: Windows keywords: 3.8regression messages: 369091 nosy: jaraco, paul.moore, steve.dower, tim.golden, zach.ware priority: normal severity: normal status: open title: shutil.copyfile mutates symlink for absolute path type: behavior versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40654> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
