Is it a crazy idea to read the cvs files, compute an sha1 on each expanded delta and then write the delta straight into a pack file? Are the cvs and git delta formats the same? What about CVS's forward and reverse delta use? While this is going on, track the branches/changsets in memory and then finish up by writing these trees into the pack file too. This should take no more ram than cvsps needs currently. This leaves the packfile is a non-optimal format but a repack should fix that, right? -- Jon Smirl jonsmirl@xxxxxxxxx - : send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
