rsync - Feb 2006 - DO NOT REPLY [Bug 3542] New: "rsync --list-only a b/" tries to create b

https://bugzilla.samba.org/show_bug.cgi?id=3542

           Summary: "rsync --list-only a b/" tries to create b
           Product: rsync
           Version: 2.6.7
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P3
         Component: core
        AssignedTo: wayned@samba.org
        ReportedBy: hashproduct@verizon.net
         QAContact: rsync-qa@samba.org


Rsync's --list-only option requires a destination, which is strange because
the
destination isn't used for anything.  Nevertheless, in get_local_name, rsync
ensures that the destination is usable, which may involve trying to create the
destination as a directory.  Luckily, if rsync tries to create the directory,
the attempt is caught in do_mkdir and an error message results, but rsync
really shouldn't care about the destination at all.

The patch I will soon attach causes get_local_name to return NULL immediately
if --list-only is given.  However, there has to be a better way to ensure the
destination is not touched in this situation.

Separately, it would be an improvement if the destination argument could be
omitted when --list-only is given.  (Until I read the man page, I kept trying
to run "rsync --list-only source/" and wondered why I got a usage
error.)

Thanks!  This is now fixed in CVS.

Also, rsync no longer returns a usage error when used with one local source arg
and no destination: this now implies the --list-only option, just like the
comparable situation with a remote source arg.
