rsync - Mar 2014 - [Bug 10497] New: rsync fails to sync certain sparse file combinations with compression

https://bugzilla.samba.org/show_bug.cgi?id=10497

           Summary: rsync fails to sync certain sparse file combinations
                    with compression
           Product: rsync
           Version: 3.1.1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: core
        AssignedTo: wayned at samba.org

I am finding that rsync is failing to sync up certain combinations (sender and
receiver) of sparse files when using compression.  With 3.1.1pre1 I just see:

# rsync -axHS -z --msgs2stderr
/export/images/Fedora-Minimal-armhfp-20-1-sda.raw barry:/export/tmp/
rsync: [sender] write error: Broken pipe (32)
rsync error: error in rsync protocol data stream (code 12) at io.c(820)
[sender=3.1.1pre1]

With some older versions I can see the server fail with "inflate returned
-3 (0
bytes)", so it appears that the compressed stream is getting corrupted
somehow.

strace of the server with 3.1.1pre1 just shows it quitting:

[pid  2216] exit_group(12)              = ?
[pid  2216] +++ exited with 12 +++

Interestingly, this appears to be one of those situations in 3.1.0 fixed in
3.1.1pre1 where the temp file would be left around.

I'd imagine that this is a duplicate of 10372.  See that bug for some
suggestions.
