      expires: refactoring judgment about whether a key is expired · e542132b
      zhaozhao.zz authored
      Calling lookupKey*() many times to search a key in one command
      may get different result.
      
      That's because lookupKey*() calls expireIfNeeded(), and delete
      the key when reach the expire time. So we can get an robj before
      the expire time, but a NULL after the expire time.
      
      The worst is that may lead to Redis crash, for example
      `RPOPLPUSH foo foo` the first time we get a list form `foo` and
      hold the pointer, but when we get `foo` again it's expired and
      deleted. Now we hold a freed memory, when execute rpoplpushHandlePush()
      redis crash.
      
      To fix it, we can refactor the judgment about whether a key is expired,
      using the same basetime `server.cmd_start_mstime` instead of calling
      mstime() everytime.
