Re: [wildfly-dev] The art, science, and torture of debugging test suite hangs

It's really a pain when you are developing a multifaceted change to the application server and it hangs. Sometimes, if you're lucky, you can stick jconsole on there and figure out at least a general idea of what is going on, or reproduce the problem by running a test, a test class, or a test module in isolation with debugging turned on. Sometimes you're not so lucky, or sometimes the hang happens in the manualmode test suite where you have to attach a debugger 9,000 times only to find out that the hang doesn't happen when you do that. I think we should introduce a new build profile which activates the remote debugging port, but with suspend=n. This would allow entire full test suite runs to be done while allowing debugger to be attached for exploratory surgery in the event that something goes wrong. While it's possible that having debugging activated might actually prevent the hang you care about, at least there's a chance that something can be done. -- - DML _______________________________________________ wildfly-dev mailing list wildfly-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/wildfly-dev
