如何使用 dulwich 检出特定文件或目录
How to checkout specific files or directories with dulwich
我有一个基于 dulwich 的有效结帐功能:
def checkout(repo, ref=None):
if ref is None:
ref = repo.head()
index = repo.index_path()
tree_id = repo[ref].tree
build_index_from_tree(repo.path, index, repo.object_store, tree_id)
return [repo.object_store.iter_tree_contents(tree_id)]
但是我该如何修改它以签出单个文件或目录?
有什么东西可以代替 build_index_from_tree
行吗?

内联 build_index_from_tree() 的内容,然后添加一个 if 语句以过滤掉任何没有以您的路径开头的 entry.path 的条目:
if subpath[-1] != "/":
subpath += "/"
if not isinstance(root_path, bytes):
root_path = root_path.encode(sys.getfilesystemencoding())
for entry in object_store.iter_tree_contents(tree_id):
if not validate_path(entry.path, validate_path_element_default):
continue
# new lines added here:
if not entry.path.startswith(subpath):
continue
full_path = _tree_to_fs_path(root_path, entry.path[len(subpath):])
if not os.path.exists(os.path.dirname(full_path)):
os.makedirs(os.path.dirname(full_path))
obj = object_store[entry.sha]
build_file_from_blob(obj, entry.mode, full_path)
