關於Android 4.0編譯生成Recovery的一個錯誤：ValueError: too many values to unpack

在製作差分包的過程中發現這個問題，後來發現這個項目在編譯的過程中就已經報錯了，只是不影響.img .bin文件的生成而已。

錯誤提示：

Traceback (most recent call last):
  File "./build/tools/releasetools/ota_from_target_files", line 1107, in <module>
    main(sys.argv[1:])
  File "./build/tools/releasetools/ota_from_target_files", line 1075, in main

    name, uid, gid, mode = line.split()

錯誤的函數：

  def GetMetadata(cls, input_zip):

    try:
      # See if the target_files contains a record of what the uid,
      # gid, and mode is supposed to be.
      output = input_zip.read("META/filesystem_config.txt")
    except KeyError:
      # Run the external 'fs_config' program to determine the desired
      # uid, gid, and mode for every Item object.  Note this uses the
      # one in the client now, which might not be the same as the one
      # used when this target_files was built.
      p = common.Run(["fs_config"], stdin=subprocess.PIPE,
                     stdout=subprocess.PIPE, stderr=subprocess.PIPE)
      suffix = { False: "", True: "/" }
      input = "".join(["%s%s\n" % (i.name, suffix[i.dir])
                       for i in cls.ITEMS.itervalues() if i.name])
      output, error = p.communicate(input)
      assert not error

    for line in output.split("\n"):
      if not line: continue
      name, uid, gid, mode = line.split()
      i = cls.ITEMS.get(name, None)
      if i is not None:
        i.uid = int(uid)
        i.gid = int(gid)
        i.mode = int(mode, 8)
        if i.dir:
          i.children.sort(key=lambda i: i.name)

    # set metadata for the files generated by this script.
    i = cls.ITEMS.get("system/recovery-from-boot.p", None)
    if i: i.uid, i.gid, i.mode = 0, 0, 0644
    i = cls.ITEMS.get("system/etc/install-recovery.sh", None)
    if i: i.uid, i.gid, i.mode = 0, 0, 0544

解決：這個問題最終解決了，首先回顧項目背景

改項目有通過暗碼可以切換19個運營商，因爲各個運營商開關機動畫，壁紙等不一樣，還有一些出廠自帶的apk，也對有的apk做了過濾，爲了能正常切換對應運營商實現不同定製，生成編譯文件系統中添加了 /SYSTEM/vendor/thirdparty目錄並且添加了客戶提供的幾個apk。

在編譯後filesystem_config.txt中也有該目錄的體現。但是因爲提交apk時直接按照客戶給的，沒有重命名apk，而apk名字中有空格，就導致了該問題。
