Gitlab设置自动代码规范检查

使用Gitlab给公司搭建了一套Git仓库服务器,结合OpenLDAP授权给研发人员使用已经半年有余了,大家也逐渐适应了新的Git Flow(工作流),期间也遇到了很多问题或者需求,比如:

  • 怎么禁止提交不安全的文件类型?
  • 怎么强制研发人员遵守代码规范?

目的是:

  • 通过限制文件类型,可以禁止研发上传例如.rar/.zip/.gz/.tgz/.mdb/.sql/.bak等文件,防止研发备份的程序或者代码通过自动发布系统上传到服务器后,被黑客恶意下载从而导致信息数据泄露。另外限制二进制数据还可以节省Git服务器空间

  • 强制研发人员遵守代码规范,简洁整齐、规范统一的代码让别人读起来会更容易理解,团队协作也会更高效,因此从Git服务器上进行严格规范限制,不合格的代码不让提交

自然想到的解决办法就是使用Git的pre-receive钩子了。

我的Git服务器目录结构如下:

/data/git-data/
├───────────── custom_hooks
│              ├── pre-receive   # 钩子脚本
├───────────── repositories      # Git数据目录
└───────────── set_hook.sh       # 计划任务脚本(对新增仓库自动添加custom_hooks)
一、下载安装phpcs

下载phpcs(PHP_CodeSniffer)工具

注意: phpcs依赖php运行环境,请提前自行安装php

wget -O /usr/local/bin/phpcs \
https://github.com/squizlabs/PHP_CodeSniffer/releases/download/3.0.2/phpcs.phar
chmod +x /usr/local/bin/phpcs
二、设置hooks脚本

自定义钩子脚本

  • 创建/data/git-data/custom_hooks目录,用于存放钩子脚本
  • 创建/data/git-data/custom_hooks/pre-receive文件,脚本内容如下:
#!/usr/bin/env bash
#
# Pre-receive hook that will block any new commits that contain files ending
# with .gz, .zip or .tgz .sql .log .svn
#
# More details on pre-receive hooks and how to apply them can be found on
# https://help.github.com/enterprise/admin/guides/developer-workflow/managing-pre-receive-hooks-on-the-github-enterprise-appliance/
#
#TEMPDIR=`mktemp -d --tmpdir=/dev/shm`

zero_commit="0000000000000000000000000000000000000000"

# Do not traverse over commits that are already in the repository
# (e.g. in a different branch)
# This prevents funny errors if pre-receive hooks got enabled after some
# commits got already in and then somebody tries to create a new branch
# If this is unwanted behavior, just set the variable to empty
excludeExisting="--not --all"

RETVAL=0

while read oldrev newrev refname; do
    # branch or tag get deleted
    if [ "$newrev" = "$zero_commit" -o "$oldrev" = "$zero_commit"  ]; then
        continue
    fi

    newfiles=`git diff --name-only --diff-filter=A $oldrev $newrev`

    for FILE in $newfiles
    do
        case $FILE in
            *.ipk|*.ipa|*.apk|*.war|*.exe|*.db|*.zip|*.rar|*.gz|*.tgz|*.7z|*.log|*.ai|*.psd|*.svn|*.bak|*Thumbs.db|.idea )
                echo "+================================ ERROR =============================+"
                echo "| FILE:    $FILE"
                echo "| REFNAME: $refname"
                echo "| OLDREV:  $oldrev"
                echo "| NEWREV:  $newrev"
                echo "+============================== 禁止提交 ============================+"
                RETVAL=1
            ;;
            *.php | *.php5 )
                if [ -n "echo $f|grep -oP '.+/(Org/Thrift|Vendor)/.+'" ]; then
                    continue      # 忽略的目录
                fi
                if [ "$f" = "$FILE" ]; then
                    object=`git ls-tree --full-name -r ${newrev} | egrep "(\s)${FILE}\$" | awk '{ print $3 }'`
                    if [ -z ${object} ]; then continue; fi
                    git cat-file blob ${object} | /usr/local/bin/phpcs --error-severity=1 --warning-severity=8 --extensions=php,php5 --standard=PSR2 --ignore=*/Run/*,*/Runtime/*
                    if [ $? -eq 0 ]; then continue; fi
                    echo "+================================ ERROR =============================+"
                    echo "| FILE:    $FILE"
                    echo "| REFNAME: $refname"
                    echo "| OLDREV:  $oldrev"
                    echo "| NEWREV:  $newrev"
                    echo "+============================== 校验错误 ============================+"
                    RETVAL=1
                fi
            ;;
        esac
    done
done
exit $RETVAL
  • 修改目录和文件权限
chmod -R 755 /data/git-data/custom_hooks
三、设置计划任务

创建计划任务脚本、设置计划任务,自动将custom_hooks目录链接到相应Git仓库下使之生效。

/data/git-data/set_hook.sh脚本如下:

#!/bin/sh

# 忽略一些目录
/bin/find /data/git-data/repositories/ -name '*.git' ! -name '*.wiki.git' ! -path '*/mob/*' ! -path '*/docs/*' ! -path '*/ops/*' -type d | while read gitdir
do
    /bin/ln -s /data/git-data/custom_hooks $gitdir/   # 创建软连接
done

加可执行权限

chmod +x /data/git-data/set_hook.sh

crontab -e创建计划任务,每天执行一次:

0 0 * * * /data/git-data/set_hook.sh
