I am writing a Python C extension that contains multiple C pthreads. Eventually these threads are sent a SIGTERM in order for them to exit. When I step through the extension in GDB these threads exit successfully, and I return back to the Python interpreter where I can continue to run commands. It is also working successfully in the Python interpreter.
However, when I try to run a Python file that contains similar behavior, the entire program terminates after the signal is sent to the child thread.
I am confused as to how the signal is propagating up from the threads to the program itself, any guidance is appreciated.
