When I have revert this only file to the version of 2012-09-18 - cache.disk
is working again
below the method from that file, which have became errorous in the last
versions:
def _open_shelf_with_lock(self):
"""Open and return a shelf object, obtaining an exclusive lock
on self.locker first. Replaces the close method of the
returned shelf instance with one that releases the lock upon
closing."""
def _close(self):
try:
shelve.Shelf.close(self)
finally:
portalocker.unlock(self.locker)
self.locker.close()
storage, locker, locker_locked = None, None, False
try:
locker = open(self.locker_name, 'a')
portalocker.lock(locker, portalocker.LOCK_EX)
locker_locked = True
storage = shelve.open(self.shelve_name)
storage.close = _close.__get__(storage, shelve.Shelf)
storage.locker = locker
except Exception:
logger.error('corrupted cache file %s, will try to delete and
recreate it!' % (self.shelve_name))
if storage:
storage.close()
storage = None
try:
os.unlink(self.shelve_name)
storage = shelve.open(self.shelve_name)
storage.close = _close.__get__(storage, shelve.Shelf)
storage.locker = locker
if not CacheAbstract.cache_stats_name in storage.keys():
storage[CacheAbstract.cache_stats_name] = {
'hit_total': 0,
'misses': 0,
}
storage.sync()
except (IOError, OSError):
logger.warn('unable to delete and recreate cache file %s' %
self.shelve_name)
if storage:
storage.close()
storage = None
if locker_locked:
portalocker.unlock(locker)
if locker:
locker.close()
return storage
