rsync - Nov 2012 - [Bug 9416] New: --files-from : RERR_PARTIAL vs RERR_VANISHED

https://bugzilla.samba.org/show_bug.cgi?id=9416

           Summary: --files-from : RERR_PARTIAL vs RERR_VANISHED
           Product: rsync
           Version: 3.1.0
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: penning at uu.nl
         QAContact: rsync-qa at samba.org


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:

    --ignore-missing-args
    --delete-missing-args
