Shawn O. PearceMy sp/mmap changes to pack-check.c modified the function such that it expects packed_git.pack_size to be populated with the total bytecount of the packfile by the caller.
But that isn't the case for packs obtained by git-http-fetch as pack_size was not initialized before being accessed. This caused verify_pack to think it had 2^32-21 bytes available when the downloaded pack perhaps was only 305 bytes in length. The use_pack function then later dies with "offset beyond end of packfile" when computing the overall file checksum.

For the tip of my sp/mmap topic. Without it HTTP fetch and push support is severely broken as it cannot deal with packs.
