以编程方式`与gul结帐.`与德威 [英] Programmatically `git checkout .` with dulwich

问题描述

从dulwich.objects获得此代码

Having this code

from dulwich.objects import Blob, Tree, Commit, parse_timezone
from dulwich.repo import Repo
from time import time

repo = Repo.init("myrepo", mkdir=True)
blob = Blob.from_string("my file content\n")
tree = Tree()
tree.add("spam", 0100644, blob.id)
commit = Commit()
commit.tree = tree.id


author = "Flav <[e-mail]>"
commit.author = commit.committer = author
commit.commit_time = commit.author_time = int(time())
tz = parse_timezone('+0200')[0]
commit.commit_timezone = commit.author_timezone = tz
commit.encoding = "UTF-8"
commit.message = "initial commit"

o_sto = repo.object_store
o_sto.add_object(blob)
o_sto.add_object(tree)
o_sto.add_object(commit)

repo.refs["HEAD"] = commit.id

结束历史提交，但创建的文件正在等待删除（ git status 这样说）。

I end up with the commit in the history, BUT the created file is pending for deletion (git status says so).

一个 git checkout。修正了它。

我的问题是：如何执行 git checkout。以编程方式使用dulwich？

My question is: how to do git checkout . programmatically with dulwich?

推荐答案

现在可以自版本0.8.4 ，方法 dulwich.index.build_index_from_tree（）。

它为索引文件和文件系统（工作副本）写了一个树，这是一种非常基本的结帐形式。

It writes a tree to both the index file and the filesystem (working copy), which is a very basic form of checkout.

查看注释

See the note

现有索引已被擦除，内容未在工作目录中合并
。仅适用于新鲜克隆

existing index is wiped and contents are not merged in a working dir. Suiteable only for fresh clones

我可以使用以下代码来工作

I could get it work with the following code

from dulwich import index, repo
#get repository object of current directory
repo = repo.Repo('.')
indexfile = repo.index_path()
#we want to checkout HEAD
tree = repo["HEAD"].tree

index.build_index_from_tree(repo.path, indexfile, repo.object_store, tree)
