如何使用 GitPython 进行浅克隆 过滤器规格可以作为列表传递

编程问答 2022-04-24

问题描述

我正在尝试使用 GitPython 对存储库进行浅层/部分克隆

这是 git CLI 命令：

$ git clone -v --filter=tree:0 --filter=blob:none --sparse [email protected]:gitlab-org/gitlab-docs.git ./Projects/ 
Cloning into './Projects'...
remote: Enumerating objects: 4145,done.
remote: Counting objects: 100% (71/71),done.
remote: Compressing objects: 100% (64/64),done.

Receiving objects: 100% (31/31),182.70 KiB | 2.31 MiB/s,done.
Updating files: 100% (31/31),done.

尝试使用 GitPython 包通过 python 运行相同的命令：

代码：

from git import Repo


print('cloning ....')
repo = Repo.clone_from(
        '[email protected]:gitlab-org/gitlab-docs.git','./Projects/',filter='{tree:0,blob:none}',sparse=True
        )   
print(repo)

输出：

% python test.py 
cloning ....
Traceback (most recent call last):
  File "/partial_clone_fetch/test.py",line 5,in <module>
    repo = Repo.clone_from(
  File "/partial_clone_fetch/.env/lib/python3.9/site-packages/git/repo/base.py",line 1083,in clone_from
    return cls._clone(git,url,to_path,GitCmdObjectDB,progress,multi_options,**kwargs)
  File "/partial_clone_fetch/.env/lib/python3.9/site-packages/git/repo/base.py",line 1021,in _clone
    finalize_process(proc,stderr=stderr)
  File "/partial_clone_fetch/.env/lib/python3.9/site-packages/git/util.py",line 369,in finalize_process
    proc.wait(**kwargs)
  File "/partial_clone_fetch/.env/lib/python3.9/site-packages/git/cmd.py",line 450,in wait
    raise GitCommandError(remove_password_if_present(self.args),status,errstr)
git.exc.GitCommandError: Cmd('git') failed due to: exit code(128)
  cmdline: git clone -v --filter={tree:0,blob:none} --sparse [email protected]:gitlab-org/gitlab-docs.git ./Projects/
  stderr: 'fatal: invalid filter-spec '{tree:0,blob:none}'

不知道如何在 GitPython 中准确传递多个过滤器，并且没有足够的可用文档。
