Would it help to change all of the references in the pack from sha1 to encoded relative offsets? Then collect all of the object fetch code into a single subroutine which would change it algorithm depending on which type of pack it is operating on. Now the pack wouldn't mix reference types, they would all be encoded relative or sha1. -- Jon Smirl jonsmirl@gmail.com - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.htmlReceived on Thu Sep 07 11:00:05 2006
