Is blinker thread safe

[Neilen]

Hi,

Is blinker thread safe? Presumably if you connect to a signal your
callback will be executed in the context of the thread that does the
send(), so your callback might need to do some locking, but is blinker
itself OK with the same signals being used by multiple threads?

Thanks

Hi Neilen,

Yes, blinker is designed to be thread safe.  Any number of threads can send() on the same signal in tandem with connects, disconnects & weakref disconnects on that signal without conflicts.

You're correct that callbacks are executed in the thread that calls send() and you may need to do locking in the callback or have the callback push work into a queue for a worker thread.

Cheers,

Jason

Thanks for the clear feedback. Now I can get to work :)
