Answer 1

I haven't used dulwich, but from these doc's, possibly something like:

from dulwich.repo import Repo
from dulwich.client import HttpGitClient
local = Repo.init("local", mkdir=True)
client = HttpGitClient('http://github.com/adammorris/')
remote_refs = client.fetch("history.js.git",local)
local["HEAD"] = remote_refs["refs/heads/master"]

At this point, it didn't load the files, but I could do "git checkout" from the local path, and it updated the files.

Also, saw these:

• Programmatically `git checkout .` with dulwich

Yes, the fetch function will pull in a pack file under .git directory. And I just don't know how to merge it into master branch. – Regen

It sounds like fetch() should import the pack into same branch as the repo. Is possible to use do_commit() to merge it into the master branch? #6905234 – Seventeenth

Tried this and found I needed to set the refs first, like local["HEAD"] = remote_refs["refs/heads/master"] - saw this also: #6641046 – Seventeenth

Full example. Works with Bitbucket.

from dulwich import index
from dulwich.client import HttpGitClient
from dulwich.repo import Repo

local_repo = Repo.init(LOCAL_FOLDER, mkdir=True)
remote_repo = HttpGitClient(REMOTE_URL, username=USERNAME, password=PASSWORD)
remote_refs = remote_repo.fetch(REMOTE_URL, local_repo)
local_repo[b"HEAD"] = remote_refs[b"refs/heads/master"]

index_file = local_repo.index_path()
tree = local_repo[b"HEAD"].tree
index.build_index_from_tree(local_repo.path, index_file, local_repo.object_store, tree)

Replace LOCAL_FOLDER, REMOTE_URL, USERNAME, PASSWORD with your data.
