           Summary: Random false checksum mismatches
           Product: rsync
           Version: 3.0.7
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P3
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: matt at mattmccutchen.net
         QAContact: rsync-qa at samba.org


Under circumstances that are not fully understood but appear to be related to
the presence of a transfer and a deletion in a previous directory, rsync 3.0.7
sometimes reports a checksum mismatch for files whose contents are in fact
identical on source and destination.

Original report by Mikolaj Kucharski:
https://lists.samba.org/archive/rsync//2011-January/025988.html

A minimized test case:

mkdir src src/sub
touch src/1 src/2 src/sub/file
rsync -a src/ dest/
echo data >src/1
rm src/2

rsync -nvi -rc --delete src/ dest/
