비커 캐시는 TypeError를 불평합니다

Question

Beaker Cache는 TypeError를 불평합니다.나는 Google에서 추적 된 비커의 이슈 트래커를 검색했지만 아무 것도 찾을 수 없었습니다.

다음과 같은 쿼리를 캐시합니다.

@staticmethod
def get_queries(query):
    @cache.cache(query, type = 'file', expire = 300)
    def load(query):
        entries = db.get_expensive_query(query)
        return entries
    return load(query)

.

그러나 프로그램을 실행하면 이는 내가받는 것입니다.

  File "/Users/ivan/project/controller/caching.py", line 15, in get_queries
      return load(query)
  File "/Library/Python/2.6/site-packages/Beaker-1.5.4-py2.6.egg/beaker/cache.py", line 417, in cached
    return cache[0].get_value(cache_key, createfunc=go)
  File "/Library/Python/2.6/site-packages/Beaker-1.5.4-py2.6.egg/beaker/cache.py", line 214, in get
    return self._get_value(key, **kw).get_value()
  File "/Library/Python/2.6/site-packages/Beaker-1.5.4-py2.6.egg/beaker/container.py", line 256, in get_value
    if not self._is_expired(stored, expired):
  File "/Library/Python/2.6/site-packages/Beaker-1.5.4-py2.6.egg/beaker/container.py", line 245, in _is_expired
    time.time() >= expiretime + storedtime
TypeError: cannot concatenate 'str' and 'float' objects

.

나는 뭔가 잘못하고 있거나 이것이 비커 버그인가?

Answer 1

Your code calls cache.cache with an integer for expire, which is correct, but clearly either expiretime or storedtime is winding up with a string. [From the error message it has to be expiretime. --ed] So here's what I think happened:

(1) You called cache.cache with a string expire at some point. [Maybe even from the default cache.expire in the CacheManager opts, not sure.]

(2) You fixed the bug, producing the code you submitted (which works for me).

(3) You reran the code without deleting the cache directory, and so somehow it picked up the previous state.

I can reproduce your error by following the above prescription. Could you delete your cache (everything in cache.data_dir and cache.lock_dir) and try again?
