Question

我使用GitPython 和一个空的仓库, 我试图通过 SHA 获得特定的 Git 对象。如果我直接使用 Git Git, 我会这样做

git ls-tree sha_of_tree
git show sha_of_blob

既然我用吉特皮森和我想买一棵树我就做以下工作:

repo = Repo("path_to_my_repo")
repo.tree("b466a6098a0287ac568ef0ad783ae2c35d86362b")

把这个拿回来

<git.Tree "b466a6098a0287ac568ef0ad783ae2c35d86362b">

现在我有一个树物, 但我无法访问它的属性, 如路径、名称、布料等等。

repo.tree("b466a6098a0287ac568ef0ad783ae2c35d86362b").path

Traceback (most recent call last):

File "<stdin>", line 1, in <module>
File "c:Python27libsite-packagesgitdbutil.py", line 238, in __getattr__
self._set_cache_(attr)
File "c:Python27libsite-packagesgitobjects	ree.py", line 147, in _set_cache_
super(Tree, self)._set_cache_(attr)
File "c:Python27libsite-packagesgitobjectsase.py", line 157, in _set_cache_
raise AttributeError( "path and mode attributes must have been set during %s object creation" % type(self).__name__ )
AttributeError: path and mode attributes must have been set during Tree object creation

但如果我输入以下输入,它就会有效

repo.tree().trees[0].path

The other part of my question is how to get a blob object with GitPython. I noticed that the only object tree has attribute blobs, so in order to get blob by SHA, I have to (a) first know which tree it belongs to, (b) find this blob, and then (c) call the data_stream method. I could just do

repo.git.execute("git show blob_sha")

但我想首先知道,这是这样做的唯一办法。

尝试此 :

   def read_file_from_branch(self, repo, branch, path, charset= ascii ):
               
            return the contents of a file in a branch, without checking out the
            branch
               
            if branch in repo.heads:
                blob = (repo.heads[branch].commit.tree / path)
                if blob:
                    data = blob.data_stream.read()
                    if charset:
                        return data.decode(charset)
                    return data
            return None

Answer 2

一般而言,一棵树有孩子,这些孩子是小树和更多的树,这些小树是树上直接的孩子,其他树是指导那棵树的孩子的目录。

直接访问树下的文件 :

repo.tree().blobs # returns a list of blobs

直接访问此树下方的目录 :

repo.tree().trees # returns a list of trees

看看子目录中的浮肿如何:

for t in repo.tree().trees:
    print t.blobs

让我们从前面获得第一个浮点的路径 :

repo.tree().blobs[0].path # gives the relative path
repo.tree().blobs[0].abspath # gives the absolute path

希望这能让您更好地了解如何浏览这个数据结构以及如何访问这些天体的属性。

我之所以寻找这个是因为我也有同样的问题, 我找到了一个解决办法:

>>> import binascii
>>> id_to_find = repo.head.commit.tree[ README ].hexsha  # For example
>>> id_to_find
"aee35f14ee5515ee98d546a170be60690576db4b"
>>> git.objects.blob.Blob(repo, binascii.a2b_hex(id_to_find))
<git.Blob "aee35f14ee5515ee98d546a170be60690576db4b">

我觉得应该有办法通过回购来引用Blob, 但我找不到它。
