根据文件路径、commit id、 批量获取ｐａｔｃｈ

　　根据已知文件路径，和ｃｏｍｍｉｔ ID，遍历仓库，获取ｐａｔｃｈ。文件路径和ｃｏｍｍｉｔ id以如下文件格式给出：

system / core / ecf5fd58a8f50362ce9e8d4245a33d56f29f142bframeworks / base / e739d9ca5469ed30129d0fa228e3d0f2878671acframeworks / av / 119a012b2a9a186655da4bef3ed4ed8dd9b94c26frameworks / av / 1e9801783770917728b7edbdeff3d0ec09c621ac

　　思路：以行的方式读取文件，获取字符串后分别解析出路径和ｃｏｍｍｉｔ　ｉｄ ;  通过ｐｙｔｈｏｎ　ｏｓ库操作ｓｈｅｌｌ命令，切换文件目录，使用ｇｉｔ　ｆｏｒmat -patch生成ｐａｔｃｈ

完整ｃｏｄｅ如下：

#!/usr/bin/python# coding:utf-8import os# 分割字符串def deal_string(string):    str_list = []    for i in string.split("/"):        str_list.append(i.strip())    return str_list# 生成patchdef product_patch(str_list):    length = str_list.__len__()    directory = "/tmp/patches/2016_09/"     # patch打包路径    code_dir = "/work/android/"  # code 路径    commit_id = str_list[length-1]    for i in range(length-1):                      # len-1前为路径,len-1为commit id        directory = directory + str_list[i] + "/"        code_dir = code_dir + str_list[i] + "/"    if os.path.exists(directory) is False:        os.makedirs(directory)                     # 生成patch目录    os.chdir(code_dir)                # 切换到code工作区    command = 'git format-patch ' + commit_id + ' -1 '   # 生成patch    os.system(command)    os.system('mv *.patch ' + directory)            # 移动patchif __name__ == '__main__':    filename = '2016_09.txt'    open_file = open(filename, 'r')    for line in open_file:        line_list = deal_string(line)        product_patch(line_list)    open_file.close()
