[Bug 1582] New: rsync dry run cannot find missing folders, contradicts actual run.

https://bugzilla.samba.org/show_bug.cgi?id=1582

           Summary: rsync dry run cannot find missing folders, contradicts
                    actual run.
           Product: rsync
           Version: 2.6.2
          Platform: All
        OS/Version: IRIX
            Status: NEW
          Severity: normal
          Priority: P3
         Component: core
        AssignedTo: wayned@samba.org
        ReportedBy: weyerse@sgi.com
         QAContact: rsync-qa@samba.org


If you are telling rsync to sync to a folder which does not exist, it would
normally create the folder and then continue to run normally.  But if you were
to use the -n dry run option, it can not create the folder and errors out.  This
leaves a user confused as to what happened.

Here is an example, in this example, junkdir does not exist on elk but does
exist on the host.  Normally rsync would then create the directory then copy the
junkdir4 directory as it should.  But with the dry run option (and the -vvv
debugging option to show what is happening) I get this:

/sw/pd/bin/rsync262 -azvvvn --delete --rsync-path=/sw/pd/bin/rsync262
/export/sw/irix/testirix6/junkdir/junkdir4
elk:/export/sw/irix6/sw01/testirix6/junkdir/
opening connection using rsh elk /sw/pd/bin/rsync262 --server -vvvnlogDtprz
--delete . /export/sw/irix6/sw01/testirix6/junkdir/

Now if I were to run this without the -n option, it would run normally, which
contradicts what -n option tells us.

This becomes a problem because we need the dry run to work exactly as a normal
run would, only without actually running.  Therefore a user can find out what
will happen in rsyncing the directories without it actually happening.  If they
find they have this error then running the normal command would be questionable.

I hope this report has been satisfactory.
