  • 0

I would like to know why doesn’t python2.7 drop blocking operations when ctrl+c is pressed, I am unable to kill my threaded application, there are several socket waits, semaphore waits and so on. In python3 ctrl+c dropped every blocking operation and garbage-collected everything, released all the sockets and whatsoever … Is there (I am convinced there is, I just yet don’t know how) a way to acomplish this? Signal handle? Thanks guys

    I guess you are launching the threads and then the main thread is waiting to join them on termination.

    You should catch the exception generated by Ctrl-C in the main thread, in order to signal the spawned threads to terminate (changing a flag in each thread, for instance). In this manner, all the children thread will terminate and the main thread will complete the join call, reaching the bottom of your main.
