uwsgi.cache_set() not working in separate thread inside a mule process

0

For experiment, I set up a cache uwsgi.cache_set('test', data) inside a mule process. The cache is set as expected.

Now I spawn a thread from which I can access that cache

---

Threading is enabled in uwsgi.ini:

[uwsgi]
threads = 4

---

in mule.py:

#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()

The question is why does this happen and how do I set caches from inside a thread.

OK it seems like I used the wrong function (cache_set) instead of 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.
