           Summary: 2.6.9 client cannot receive files from 3.0.0 server
           Product: rsync
           Version: 3.0.0
          Platform: x86
        OS/Version: Windows XP
            Status: NEW
          Severity: major
          Priority: P3
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: ruralrob at gmail.com
         QAContact: rsync-qa at samba.org


My client is a Windows machine running rsync 2.6.9 under Cygwin. The server is
a Debian system that, until today, was also running rsync 2.6.9. Every day on
the Windows machine I would issue a command something like the following:

rsync -tzvr --delete rob at xx.xx.xx.xx:sourcepath destpath

to sync some files from the Linux machine to the Windows machine. This worked
fine until today, when I upgraded rsync on the server to 3.0.0. (The newer
version is not available for Cygwin yet). Now when I try to do the above
operation, I get:

Invalid block length 146536 [sender]
rsync error: protocol incompatibility (code 2) at io.c(1324) [sender=3.0.0]
rsync: connection unexpectedly closed (639 bytes received so far) [receiver]
rsync error: error in rsync protocol data stream (code 12) at
/home/lapo/packaging/tmp/rsync-2.6.9/io.c(453) [receiver=2.6.9]
rsync: connection unexpectedly closed (639 bytes received so far) [generator]
rsync error: error in rsync protocol data stream (code 12) at
/home/lapo/packaging/tmp/rsync-2.6.9/io.c(453) [generator=2.6.9]

Shouldn't a 2.6.9 client still be able to copy files from a 3.0.0 server (with
the server falling back to the older protocol)?
