Description Henk Penning 2012-11-21 10:54:37 UTC
When using "--files-from list" where the list contains the name of a file that 
doest't exist on the server, rsync exits with RERR_PARTIAL.

If the only error (on the server side) is "can't lstat file", an exit with
the more specific RERR_VANISHED would be more to the point.

Context: "instant mirroring of CPAN" ; CPAN publishes (every minute) a list
of changes (files to delete or update). I use "rsync --files-from" to fetch
the updated files. In a corner-case I need to determine if a given file
actually exists on the server (if not, discard the update).

At the moment, this is hard. But if a single-file rsync would return
RERR_VANISHED if the file doesn't exist, I could use that.

So, I suggest "rsync --files-from" exits with RERR_VANISHED if the only
error is that one or more files in the list can't be lstat'ed.

Thanks, regards -- Henk Penning

In looking at this, I like the RERR_PARTIAL return better for missing args (which is what files-from files are).  However, you can use one of these to get rsync to treat missing args as OK:
