我正在尝试git log filename使用 pygit2 在 git 裸存储库中进行等效操作。该文档仅说明了如何执行git log以下操作：

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

你有什么主意吗？

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，它可以提供格式精美的输出，使用 Python 非常容易解析。例如，要获取给定文件的作者姓名、日志消息和提交哈希：

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

另一种解决方案是懒惰地从给定的提交中生成文件的修订版。由于它是递归的，如果历史记录太大，它可能会中断。

def revisions(commit, file, last=None):
    try:
        entry = commit.tree[file]
    except KeyError:
        return
    if entry != last:
        yield entry
        last = entry
    for parent in commit.parents:
        for rev in revisions(parent, file, last):
            yield rev
