uwsgi.cache_set() 不在 mule 进程内的单独线程中工作

Question

为了实验，我在 mule 进程中设置了缓存 uwsgi.cache_set('test', data)。缓存已按预期设置。

现在我生成一个线程，我可以从中访问该缓存

线程已在 uwsgi.ini 中启用：

[uwsgi]
threads = 4

在 mule.py 中：

#Threaded function
def a_function():
    uwsgi.cache_set('test', b'NOT OK') <- Nothing happens here
    cache_return = uwsgi.cache_get('test') <- Returns b'OK' which means the cache did not overwrite the previous value.

if __name__ == '__main__':
    cache = uwsgi.cache_set('test', b'OK')  <- Works here
    cache_return = uwsgi.cache_get('test') <- Return b'OK', as expected
    t = Thread(target=a_function)
    t.start()

问题是为什么会发生这种情况以及如何从线程内部设置缓存。

好吧，我好像用错了函数 (cache_set) 而不是 cache_update。

uwsgi.cache_set(key, value[, expire, cache_name])

Set a value in the cache. If the key is already set but not expired, it doesn’t set anything.

uwsgi.cache_update(key, value[, expire, cache_name])
Update a value in the cache. This always sets the key, whether it was already set before or not and whether it has expired or not.
