Bug ID: 11726
Summary: --copy-links cause rsync to fail with ancestor symlink
(..)
Product: rsync
Version: 3.1.2
Hardware: All
OS: All
Status: NEW
Severity: major
Priority: P5
Component: core
Assignee: way...@samba.org
Reporter: cyp...@cyphar.com
QA Contact: rsync...@samba.org
If you have a directory created like so:
% mkdir -p from/dir/
% ln -s .. from/dir/loop
% rsync -a --copy-links from to
rsync:
readlink_stat("/tmp/from/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop/dir/loop")
failed: Too many levels of symbolic links (40)
rsync error: some files/attrs were not transferred (see previous errors) (code
23) at main.c(1178) [sender=3.1.2]
For a trivial case of infinitely recursive symlinks (in other words when you go
through a symlink that takes you to an ancestor), rsync should just declare
"that's as far as we need to go here".
