python - pygit2 Blob 历史

Question

我正在尝试使用 pygit2 在 git 裸存储库中执行与 git log filename 等效的操作。该文档仅解释了如何像这样执行 git log:

from pygit2 import GIT_SORT_TIME
for commit in repo.walk(oid, GIT_SORT_TIME):
    print(commit.hex)

你有什么想法吗？

谢谢

编辑:

我现在有这样的事情，或多或少是精确的:

from pygit2 import GIT_SORT_TIME, Repository


repo = Repository('/path/to/repo')

def iter_commits(name):
    last_commit = None
    last_oid = None

    # loops through all the commits
    for commit in repo.walk(repo.head.oid, GIT_SORT_TIME):

        # checks if the file exists
        if name in commit.tree:
            # has it changed since last commit?
            # let's compare it's sha with the previous found sha
            oid = commit.tree[name].oid
            has_changed = (oid != last_oid and last_oid)

            if has_changed:
                yield last_commit

            last_oid = oid
        else:
            last_oid = None

        last_commit = commit

    if last_oid:
        yield last_commit


for commit in iter_commits("AUTHORS"):
    print(commit.message, commit.author.name, commit.commit_time)

我建议您只使用 git 的命令行界面，它可以提供格式良好的输出，使用 Python 非常容易解析。例如，获取给定文件的作者姓名、日志消息和提交哈希值:

import subprocess
subprocess.check_output(['git','log','--pretty="%H,%cn%n----%B----"','some_git_file.py'])

有关可以传递给 --pretty 的格式说明符的完整列表，请查看 git log 的文档:https://www.kernel.org/pub/software/scm/git/docs/git-log.html
