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...

Yeah... good point. The rdiff program should probably use a whole file
md4sum though.

Could you please forward this into the bug tracker so it's not lost?

How rsync performs synchronization
Hi--
Can someone tell me how rsync performs it?s synchronization feature? What
basic procedure does it use to check if files are different?
Thanks :)
All My Best,

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 &
