On the other hand, the size reduction is really nice (320MB vs 500MB). I don't know if we can do this, but does it make sense to apply --depth=250 for old commits only and shallow depth for recent commits? For old projects, commits older than 1-2 years is probably less often accessed and could use some aggressive packing. This still hits git-blame badly. We could even make sure all objects "on the blame surface" have short delta chain. But that may be pushing pack-objects too much. -- Duy -- To unsubscribe from this list: 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
