How to get a list of Ostream or Oinfo in a variable from a repository path in gitpython?

问题

I currently have a valid git database with no packfile, but due to a bug ingit-pack-objects(the process crashes with a stack dump file) I’m unable to perform thegit repackcommand.

I took a look at the error, and it’s linked to the C nature of the official git project (fixing would require changing corestructdefinitions) so, this will takes a lot of time to fix.

The only alternative I found which don’t use C is gitdb (part of gitpython). However I wasn’t able to find how to use thewrite_pack()function.
Or more exactly, I have no idea on how to build theobject_iterparameter from the database path from loose objects.
I don’t even know the exact class type used in theobject_iterlist.

So, how to use gitdb for that purpose ?

Solved!

#/usr/bin/python
import os,sys,zlib,gitdb
from gitdb.db import LooseObjectDB
from gitdb.pack import PackEntity
from gitdb.util import bin_to_hex,hex_to_bin

ldb=LooseObjectDB(sys.argv[1]+'/.git/objects')
PackEntity.create((ldb.stream(sha) for sha in ldb.sha_iter()),sys.argv[1]+'/.git/objects/pack',object_count=ldb.size(),zlib_compression=zlib.Z_BEST_COMPRESSION)
