Revision 8977c110b5bbd230c28c727ddb85856067d55cfb authored by Junio C Hamano on 04 January 2007, 07:09:08 UTC, committed by Junio C Hamano on 05 January 2007, 06:17:59 UTC
Running the SHA1_Update() on the whole packfile in a single call
revealed an overflow problem we had in the SHA-1 implementation
on POWER architecture some time ago, which was fixed with commit
b47f509b (June 19, 2006).  Other SHA-1 implementations may have
a similar problem.

The sliding mmap() series already makes chunked calls to
SHA1_Update(), so this patch itself will become moot when it
graduates to "master", but in the meantime, run the hash
function in smaller chunks to prevent possible future problems.
