Git internals : packfile and packfile index

[Maxzor]

Trying to get for now those KSY up :

• git packfile - .git/objects/pack/*.pack
• git packfile index - .git/objects/pack/*.idx

Will maybe tackle multi-index later.

Docs :

• http://shafiul.github.io/gitbook/7_the_packfile.html
• https://github.com/git/git/blob/HEAD/Documentation/technical/pack-format.txt

Thank to the help of @generalmimon on gitter.im , a packfile index KSY is working, see below :

Packfile is harder :

@generalmimon The git packfile is miles harder than the git packindex. Packfile is not self-sufficient for deserialization, needs either zlib, or its sibling index file :< kaitai-io/kaitai_compress#6

AFAIU my options are :

• find a magic byte at the end of the zlib stream
• process: zlib.inflate with the linked-above WIP project
• parse simultaneously in ide.kaitai.io/devel two files
• recode c git internals to not have two files to do the job of one file
• do nothing
