我想在Python脚本的输出中包含当前的git散列(作为生成该输出的代码的版本号)。
如何在我的Python脚本中访问当前的git哈希?

这是对富田裕治‘富田’的改进回答。
import subprocess
def get_git_revision_hash():
full_hash = subprocess.check_output(['git', 'rev-parse', 'HEAD'])
full_hash = str(full_hash, "utf-8").strip()
return full_hash
def get_git_revision_short_hash():
short_hash = subprocess.check_output(['git', 'rev-parse', '--short', 'HEAD'])
short_hash = str(short_hash, "utf-8").strip()
return short_hash
print(get_git_revision_hash())
print(get_git_revision_short_hash())

如果您由于某些原因没有可用的Git,但您有Git repo(。),你可以从. Git /fetch/heads/[branch]中获取提交哈希。
例如,我在存储库根运行了下面的Python代码片段来获得提交id:
git_head = '.git\\HEAD'
# Open .git\HEAD file:
with open(git_head, 'r') as git_head_file:
# Contains e.g. ref: ref/heads/master if on "master"
git_head_data = str(git_head_file.read())
# Open the correct file in .git\ref\heads\[branch]
git_head_ref = '.git\\%s' % git_head_data.split(' ')[1].replace('/', '\\').strip()
# Get the commit hash ([:7] used to get "--short")
with open(git_head_ref, 'r') as git_head_ref_file:
commit_id = git_head_ref_file.read().strip()[:7]
下面是格雷格更完整的回答:
import subprocess
print(subprocess.check_output(["git", "describe", "--always"]).strip().decode())
或者,如果脚本从repo外部被调用:
import subprocess, os
print(subprocess.check_output(["git", "describe", "--always"], cwd=os.path.dirname(os.path.abspath(__file__))).strip().decode())
或者,如果脚本是从repo外部调用的,而你喜欢pathlib:
import subprocess
from pathlib import Path
print(subprocess.check_output(["git", "describe", "--always"], cwd=Path(__file__).resolve().parent).strip().decode())

def get_git_revision_hash():
full_hash = subprocess.check_output(['git', 'rev-parse', 'HEAD'])
full_hash = str(full_hash, "utf-8").strip()
return full_hash
def get_git_revision_short_hash():
short_hash = subprocess.check_output(['git', 'rev-parse', '--short', 'HEAD'])
short_hash = str(short_hash, "utf-8").strip()
return short_hash
print(get_git_revision_hash())
print(get_git_revision_short_hash())
如果subprocess是不可移植的,并且你不想安装一个包来做这么简单的事情,你也可以这样做。
import pathlib
def get_git_revision(base_path):
git_dir = pathlib.Path(base_path) / '.git'
with (git_dir / 'HEAD').open('r') as head:
ref = head.readline().split(' ')[-1].strip()
with (git_dir / ref).open('r') as git_hash:
return git_hash.readline().strip()
我只测试了这个在我的回购,但它似乎工作相当稳定。
不需要自己从git命令中获取数据。GitPython是一种很好的方式来做到这一点,还有很多其他git的东西。它甚至有对Windows的“尽最大努力”支持。
在pip安装gitpython之后你就可以做了
import git
repo = git.Repo(search_parent_directories=True)
sha = repo.head.object.hexsha
使用这个库时需要考虑的一些问题。以下文件摘自gitpython.readthedocs.io
Leakage of System Resources GitPython is not suited for long-running processes (like daemons) as it tends to leak system resources. It was written in a time where destructors (as implemented in the __del__ method) still ran deterministically. In case you still want to use it in such a context, you will want to search the codebase for __del__ implementations and call these yourself when you see fit. Another way assure proper cleanup of resources is to factor out GitPython into a separate process which can be dropped periodically
