Question

I use a thread pool and and I submit some tasks to be proccessed.

Sometimes a server that I ping or my internet connection could be down. This can be determined by any of the running threads.

In that case I would like the thread that detected the error to notify the others to pause
their execution until the error is fixed.

Do you know how is this possible?

I add to the above. The ideal solution would be :
when a threads detects the program to send a message to all other threads to wait.
Also it should notify an external server and after receiving that everything is ok from the
server to send again a signal to the other threads to continue the work.

Answer 1

I found it using threading.Event

I just have an event

event = Event()

and I use the

event.wait()

In the beggining I

event.set()

when a thread detects an error it

event.clear()

and the threads are waiting until

event.set()

This seems to work
