Should asyncio ignore KeyboardInterrupt?
by Terry Reedy 05 Jul '15

05 Jul '15

Should the loop.run... methods of asyncio respect KeyboardInterrupt (^C)? Developer and user convenience and this paragraph in PEP "However, exceptions deriving only from BaseException are typically not caught, and will usually cause the program to terminate with a traceback. In some cases they are caught and re-raised. (Examples of this category include KeyboardInterrupt and SystemExit ; it is usually unwise to treat these the same as most other exceptions.) " and this examples in the doc (two places) TCP echo server # Serve requests until CTRL+c is pressed print('Serving on {}'.format(server.sockets[0].getsockname())) try: loop.run_forever() except KeyboardInterrupt: pass suggest yes. On the other hand, the section on "Set signal handlers for SIGINT and SIGTERM" suggests not, unless an explicit handler is registered and then only on Unix. In any case, Adam Bartos, python-list, "An asyncio example", today asks. ''' This is a minimal example: import asyncio async def wait(): await asyncio.sleep(5) loop = asyncio.get_event_loop() loop.run_until_complete(wait()) Ctrl-C doesn't interrupt the waiting, instead KeyboardInterrupt occurs after those five seconds. It's 3.5.0b2 on Windows. Is it a bug? ''' Using run_forever instead, I found no way to stop other than killing the process (Idle or Command Prompt). -- Terry Jan Reedy

Please contact Robert.S.Cohn(a)intel.com if you want a free license to intel compilers or tools. From: "M.-A. Lemburg" <mal(a)egenix.com<mailto:mal@egenix.com>> Ø BTW: I remember there was some discussion a while ago to get ICC licenses to core devs. Has there been any progress on this ?
