项目里做了一个通用锁，使用 decorator 来方便的包住某些需要限制并发的函数。因为并发不是函数级别的，而是根据参数来限制，所以需要把参数传到通用锁的 decorator 里，代码大致如下
def lock_decorator(key=None):
def _lock_func(func):

关于知乎 "装修全用宜家是否合适" 的问题, 我的回答是
- 只要家具不是打算用几十年或更久, 大部分用宜家没问题, 但是需要定制化的还是去定制, 主要是尺寸问题
- 如果自己需要的某些东西有更好的专业领域提供, 且自己更了解, 那么宜家并不是最佳选择, 比如更舒服的椅子
- 宜家的产品价格并不包括运回家的运费和安装费, 如果你打算自己找朋友帮忙, 请把叫人帮忙带来的人情债也算入成本
- 如果自己装, 需要有人帮忙且有足够多合适的工具, 比如我后面借到了第二套电动螺丝刀后效率又提高了很多
长文见下
