Hi,

I notice the core doc mentions that "Most code in Twisted is not thread-safe. For example, writing data to a transport from a protocol is not thread-safe. "

I want to know whether there is a way to know what methods are thread safe besides of reading source codes? Or I use reacator.callFromThread for all related methods from threads other than reactor thread?

Yes. Unless it is clearly mentioned in a function's documentation, reactor.callFromThread is the only function that is safe to call from any thread.
