Description Petr Šplíchal 2020-10-20 15:02:11 UTC 
Description of problem:

When shutil.copytree() is used with symlinks=True and a symlink is
pointing to a non-existent file an exception is raised even if
ignore_dangling_symlinks is enabled.

Version-Release number of selected component (if applicable):
python3-3.9.0-1.fc33.x86_64

Comment 1 Miro Hrončok 2020-10-20 16:58:31 UTC 
Petr, is this something that needs to be tracked downstream?
Comment 2 Petr Viktorin (pviktori) 2020-10-21 00:27:45 UTC 
According to the docs, ignore_dangling_symlinks only takes effect if symlinks is false: https://docs.python.org/3/library/shutil.html#shutil.copytree
Should this be made more clear?
Comment 3 Petr Šplíchal 2020-10-22 08:12:49 UTC 
Thanks for clarification, Petr. Seems I've misunderstood the
ignore_dangling_symlinks parameter and got confused by a traceback
caused by wrong venv enabled. Feel free to close the issue if it
does not make sense to track it here.
