rsync - May 2009 - DO NOT REPLY [Bug 6362] New: --dry-run conflicts with --hard-links

https://bugzilla.samba.org/show_bug.cgi?id=6362

           Summary: --dry-run conflicts with --hard-links
           Product: rsync
           Version: 3.1.0
          Platform: x64
               URL: https://bugzilla.novell.com/show_bug.cgi?id=500605
        OS/Version: Linux
            Status: NEW
          Severity: minor
          Priority: P3
         Component: core
        AssignedTo: wayned@samba.org
        ReportedBy: petr.uzel@suse.cz
         QAContact: rsync-qa@samba.org


This is a forwarded bug from Novell bugzilla (see URL).

In short, rsync has problems with --dry-run and --hard-links options if the
source directory contains 'enough' hardlinked files. I'm not sure
what is the
minimum number of hardlinks to trigger the bug, though (I will try to
investigate).

I can confirm the bug with latest git development version.

------- Comment #1 from matt@mattmccutchen.net  2009-05-28 18:41 CST -------
I think there's an error in the steps to reproduce: the references to
/tmp/data
should say /tmp/X1/data.  After making that correction, I can reproduce the
problem.  It goes away if I disable incremental recursion with --no-i-r. 
Interesting.

Matt, you are correct - I forgot to mention this mistake - sorry for that.

Thanks for looking into this - I can confirm that the --no-i-r fixes the issue.
