钩子
Git钩子是在Git仓库中特定事件发生时自动运行的脚本。可以定制一些钩子,这些钩子可以在特定的情况下被执行,分为Client端的钩子和Server端的钩子。Client端钩子被operation触发,比如commit,merge等,Server端钩子被网络动作触发。

常见钩子
pre-commit pre-commit脚本在每次你运行git commit命令时,Git向你询问提交信息或者产生提交对象时被执行。
prepare-commit-msg prepare-commit-msg钩子在pre-commit钩子在文本编辑器中生成提交信息之后被调用。这被用来方便地修改自动生成的squash或merge提交。
commit-msg commit-msg钩子和prepare-commit-msg钩子很像,但它会在用户输入提交信息之后被调用。
post-commit post-commit钩子在commit-msg钩子之后立即被运行 。
post-checkout post-checkout钩子和post-commit钩子很像,但它在你用git checkout查看引用的时候被调用。
pre-rebase pre-rebase钩子在git rebase发生更改之前运行
pre-receive p re-receive钩子在有人用git push向仓库推送代码时被执行。
update update钩子在pre-receive之后被调用,分别被每个推送上来的引用分别调用。
post-receive post-receive钩子在成功推送后被调用,适合用于发送通知。
钩子使用示例
通过post-commit发送commit通知
#!/usr/bin/env python
import smtplib
from email.mime.text import MIMEText
from subprocess import check_output
# 获得新提交的git log --stat输出
log = check_output(['git', 'log', '-1', '--stat', 'HEAD'])
# 创建一个纯文本的邮件内容
msg = MIMEText("Look, I'm actually doing some work:\n\n%s" % log)
msg['Subject'] = 'Git post-commit hook notification'
msg['From'] = 'mary@example.com'
msg['To'] = 'boss@example.com'
# 发送信息
SMTP_SERVER = 'smtp.example.com'
SMTP_PORT = 587
session = smtplib.SMTP(SMTP_SERVER, SMTP_PORT)
session.ehlo()
session.starttls()
session.ehlo()
session.login(msg['From'], 'secretPassword')
session.sendmail(msg['From'], msg['To'], msg.as_string())
session.quit()
