hi folks,
where can i get information (specifications) on the format of git pack-objects... please don't say "look at the source code" unless there simply doesn't exist any format specifications. as part of the git p2p bittorrent vfs layer stuff, a "file save" operation doesn't "happen by magic": i need to actually verify the pack objects received: count the number of entries? or do i?
tia,
l.

Its in the Documentation/technical subdirectory of git.git[1]. Look at pack-format.txt. Its rather sparse though.

good enough.
.... ahh... ah ha!
- The file is concluded with a trailer:
A copy of the 20-byte SHA1 checksum at the end of
corresponding packfile.20-byte SHA1-checksum of all of the above.
i believe that will suffice.
