示例1: _scenario
# 需要导入模块: from durus.connection import Connection [as 别名]
# 或者: from durus.connection.Connection import get_root()['A'] [as 别名]
def _scenario(self):
c1 = Connection(self._get_storage())
c2 = Connection(self._get_storage())
c1.get_root()['A'] = Persistent()
c1.get_root()['B'] = Persistent()
c1.get_root()['A'].a = 1
c1.commit()
c2.abort()
c1.cache.recent_objects.discard(c1.get_root()['A'])
# Imagine c1 has been running for a while, and
# cache management, for example, has caused the
# cache reference to be weak.
return c1, c2示例2: check_fine_conflict
