GitPython 更新挂钩 SHA 无法解析

Question

我正在使用 python3.5 和 GitPython 模块编写更新挂钩。

对于初学者来说，我只是想迭代已添加/删除/修改的文件并将其保存到文件中。这是钩子：

import git
import sys

branch, oldref, newref = sys.argv[1:]
print('oldref: {0}'.format(oldref))
print('newref: {0}'.format(newref))

repo = git.Repo('/srv/test')
oldcommit = repo.commit(oldref)
newcommit = repo.commit(newref)

with open(r'/tmp/hook.stdout', 'w') as outfile:
    for diff in oldcommit.diff(newcommit):
        outfile.write('{0}\n'.format(diff.b_path))

当我尝试推送存储库时，出现以下错误：

remote: oldref: a38d324b84327e428127182b2d36b03afa73c11c
remote: newref: 1fbc70042891ecddef104f1938259b30f5f1e912
remote: Traceback (most recent call last):

remote:   File "/usr/local/lib/python3.5/dist-packages/git/repo/fun.py", line 193, in rev_parse

remote:     oinfo = repo.odb.info(sha1)
remote:   File "/usr/local/lib/python3.5/dist-packages/git/db.py", line 37, in info
remote:     hexsha, typename, size = self._git.get_object_header(bin_to_hex(sha))
remote:   File "/usr/local/lib/python3.5/dist-packages/git/cmd.py", line 940, in get_object_header
remote:     return self.__get_object_header(cmd, ref)
remote:   File "/usr/local/lib/python3.5/dist-packages/git/cmd.py", line 929, in __get_object_header
remote:     return self._parse_object_header(cmd.stdout.readline())
remote:   File "/usr/local/lib/python3.5/dist-packages/git/cmd.py", line 891, in _parse_object_header
remote:     raise ValueError("SHA could not be resolved, git returned: %r" % (header_line.strip()))
remote: ValueError: SHA could not be resolved, git returned: b''
remote: error: hook declined to update refs/heads/master

如果我手动运行脚本：

python3.5 /path_to_repo/.git/hooks/update refs/heads/master SHA1 SHA2

它运行良好并将文件名保存到文件中，我尝试过使用不同的 SHA，如果我使用错误消息中看到的 SHA 运行脚本（oldref、newref），我会得到一个空文件，但没有错误消息（因为提交已被拒绝（我想 newref SHA 不会出现在远程存储库中）。我缺少什么？

面临同样的问题，它与新版本带来的变化有关git version 2.39.3

快速解决方案将安装以前版本的 git，2.31.1直到新版本的 GitPython 发布并支持最新的 git 版本。
