on my system (Windows) queue.get() with no arguments will just hang during shutdown. I'm attempting to preserve the blocking behavior of audio_queue.get() with arguments True and 1. * True - the call still blocks, preserving your existing behavior * 1 - blocks for at most 1 second See https://docs.python.org/3/library/queue.html#queue.Queue.get for details. Specifically: """ Prior to 3.0 on POSIX systems, and for all versions on Windows, if block is true and timeout is None, this operation goes into an uninterruptible wait on an underlying lock. This means that no exceptions can occur, and in particular a SIGINT will not trigger a KeyboardInterrupt. """

please disregard this request, as I did not test this code enough and am still experiencing some breakage. |

I think my suggested edit is still valid, as without the arguments in queue.get(...) that line will hang on windows and not process a KeyboardInterrupt per the method documentation comments. I was testing my script this morning where I made a subclass inheriting AudioToTextRecorder and overloaded _recording_worker with my edits and had an inconsistent case of the reader process not terminating in time, so I wanted to run the script a few times to see if I could get some insight as to why this was happening. |
