Hello,
thanks for keeping this project alive, it's very useful. I'm looking for a way of implementing a timeout in one of the long-running tasks of my webware application. The application revolves around a web spider that crawls several tech news sites and lists the results, the long-running task is the spider itself, wrapped into a TaskKit.Task object. I'd like to set a timeout for the run of the spider, because it depends on the outside world, and it happens to hang in a non-predictable manner. (Yes, it would be best to solve that problem first. Still I want the timeout) I'm using Linux, the standard way to achieve this would be (as described in the Python manual) to create a signal handler for SIGALRM that raises an Exception in the main thread and set a signal.alarm() in the task that needs the timeout. For some reason, this one didn't work for me. I'm setting the signal handler in the __init__.py of my plugin, the signal.alarm() in the spider task. However, the alarm doesn't ring. Question 1: Did anybody implement SIGALRM / signal.alarm() successfully for a long-running task within the Webware framework? Question 2: Is there any other way to achieve a timeout-like behaviour? One idea would be to create a "watchdog" task looking after the spider task, but then again, how do you abort a TaskKit.Task() object anynchronously? BTW, if anyone is interested in having a look at the project, I'm happy to share url and password/login upon request, no questions asked. I'm not posting this freely because I'm paying huge amounts for the bandwidth used, and I fear to expose the login data in the Webware archive.
