rsync - Nov 2010 - Checksum-caching on server

Hi,

as scanning large repositories for each client connection causes
unnecessary CPU/IO load, I want to know if is it possible to generate
checksum digest files on the server, meanwhile?

Best regards,

Renne

See the 3 patches in the patches tar file that implement different kinds of
checksum caching:

   - checksum-reading.diff -- reads checksums out of a .rsyncsums file (see
   included perl script tool).
   - checksum-writing.diff -- based on checksum-reading.diff, it tries to
   update the checksum file on the fly.
   - checksum-xattr.diff -- looks for checksums in a special extended
   attribute (see included perl script tool).

The checksum-writing patch is only lightly tested, and might have issues.
 The other patches are pretty simple, and will work based on the cached
checksum info.
