I think the sending behaves like normal repack. The packfile object CRCs must match (assuming they are available, i.e. v2 index!). Loose objects might be down to zlib adler checksum. However, some errors in pack generation process could cause logically inconsistent pack to be sent. Against that, one would need to enable receive-side fsck on receive (this is how the infamous jgit push bug corrupted repositories). Transport errors are caught by underlying MACs or packfile SHA-1. > Secondary question: what happens if the receiving repo is corrupt? The push might fail or it might not. And not even receive-side fsck necressary catches the corruption (one would need full fsck for that). -Ilari -- 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
