Summary: dry run fails when encountering dangling symbolic link
Product: rsync
Version: 2.6.4
Platform: All

Status: NEW
Severity: normal
Priority: P3

Hi,
I use rsync for backup and once in a while somebody replaces a symbolic link
with the contents of the file. In this case, I find that dry-run will
report errors while rsync without -n flag works fine.
A test case can be generated like this:
mkdir old
cd old
mkdir data
ln -s data link
cd ..
mkdir new
mkdir new/link
rsync -n -arlpogt --delete new/ old/
The rsync output will be:
building file list ... done
deleting data/
deleting link
link/
Now when we delete data before, rsync fails:
rmdir old/data
rsync -n -arlpogt --delete new/ old/
building file list ... done
deleting link
rsync: opendir "/data1/ppe/tmp/old/link" failed: No such file or directory (2)
./
link/
Rsync fails with return code 23, however, if you remove the '-n' flag,
rsync is able to sync and does not report errors. I think this is an error,
because dry-run should just report that the symbolic link is updated, i.e.:
building file list ... done
./
link/
and return no error code. For me this is also a problem, because I build
scripts around rsync and I use dry-run for testing what will be done.
The script makes than a backup of the files which would be deleted. But
when dry-run fails, the script does not know whether its save to continue.
Best, Peter.
