尝试使用whisper-merge时,获取错误"TypeError:'NoneType'对象不可迭代"

Question

我正在尝试使用whisper-merge来合并2个wsp文件.它们具有相同的保留策略,一个只有比另一个更旧的数据.

当我跑步时,whisper-merge oldfile.wsp newfile.wsp我得到这个错误

Traceback (most recent call last):
  File "/usr/local/src/whisper-0.9.12/bin/whisper-merge.py", line 32, in <module>
    whisper.merge(path_from, path_to)
  File "/usr/local/lib/python2.7/dist-packages/whisper.py", line 821, in merge
    (timeInfo, values) = fetch(path_from, fromTime, untilTime)
TypeError: 'NoneType' object is not iterable

有任何想法吗？

这是2个文件的元数据输出:

• "from_file" http://sprunge.us/dBHC
• "to_file" http://sprunge.us/eIVG

对于包含多个归档的文件,whisper.py中的第812行被破坏. https://github.com/graphite-project/whisper/blob/0.9.12/whisper.py#L812

fromTime = int(time.time()) - headerFrom['maxRetention']

要在第813行之后立即修复,请根据存档保留时间分配fromTime. https://github.com/graphite-project/whisper/blob/0.9.12/whisper.py#L813

for archive in archives: # this line already exists
  fromTime = int(time.time()) - archive['retention'] # add this line
