rsync md4sum code.
G'day, I've been working on a Python interface to librsync and have noticed that it uses md4sum code borrowed from Andrew Tridgell and Martin Pool that comes via rsync and was originally written for samba. Is there anything special about this code compared to the RSA md4sum code that can be found with libmd <"http://www.penguin.cz/~mhi/libmd/">? Python uses the RSA md5sum co...

Problem with checksum failing on large files
I'm having a problem with large files being rsync'd twice because of the checksum failing. The rsync appears to complete on the first pass, but then is done a second time (with second try successful). When some debug code was added to receiver.c, I saw that the checksum for the remote file & the temp file do not match on the first try, so (as expected) it repeats the rsync & the
