[issue6547] shutil.copytree fails on dangling symlinks
Timothee Besset added the comment:
It's a symlink that points to a file that doesn't exist. There are many ways
this can happen, in this particular case my text editor (emacs) seems to keep
some metadata about which user, machine and process is editing a file. I tried
to reproduce in 2.6 (Debian sid amd64) and I can confirm it still happens:
t...@ttimozilla:~$ mkdir test
t...@ttimozilla:~$ cd test
t...@ttimozilla:~/test$ ln -s foo bar
t...@ttimozilla:~/test$ ls -1l bar
lrwxrwxrwx 1 timo timo 3 Apr 19 17:12 bar -> foo
t...@ttimozilla:~/test$ ls -1l foo
ls: cannot access foo: No such file or directory
t...@ttimozilla:~/test$ python2.6
Python 2.6.5 (r265:79063, Mar 20 2010, 03:56:44)

[issue6547] shutil.copytree fails on dangling symlinks
Timothee Besset added the comment: I am not sure what shutil does with symlinks already. At the very least it should not abort the operation. Ideally I feel it should create the same symlink pointing to a possibly missing file, since that's what '/bin/cp' does, and shutil.copytree is broadly understood as a drop in replacement.. -- ___ Python tracker <http://bugs.python.org/issue6547> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue6547] shutil.copytree fails on dangling symlinks
New submission from Timothee Besset :
shutil.copytree fails if there is a dangling symlink and symlink is set
to False (which is the default). It will raise an exception when trying
to get to the content of the symlink.
Tested on Debian Etch amd64, python 2.5.2
File "/usr/lib/python2.5/shutil.py", line 138, in copytree
raise Error, errors
shutil.Error: [('/opt/daemons/gameslave/.#fabfile.py',
'/tmp/tmphxInsp/gameslave/.#fabfile.py', "[Errno 2] No such file or
directory: '/opt/daemons/gameslave/.#fabfile.py'")]
$ ls -1l /opt/daemons/gameslave/.#fabfile.py
lrwxrwxrwx 1 timo quakelive 20 Jul 22 14:32
/opt/daemons/gameslave/.#fabfile.py -> t...@localhost.12341
(the link is created by emacs - means file being edited I'm guessing)
