And if you have a completely automated test process, it should be able to run the tests while you procure a tasty beverage of your choice.Īs already mentioned, the next step is to try to gather as much information about the bug as possible. If the bug has a 30 % chance of occurring and you run the test 20 times without seeing the bug you can be pretty certain that it has disappeared. Can you isolate the behavior that produces the bug? Can you find a way of getting a better reproduction rate? Can you script what you just did, so that you have a way of reproducing the bug that doesn't require user input?Įven if you can't find a 100 % reliable repro case, an automated test is still useful. To do that effectively you need a reliable way of reproducing the bug. I.e., change something and see if the bug is still there or not. To learn more about the bug, you need to be able to do experiments.
AUTODESK INVENTOR TUTORIAL BUG PS3
Timing issues or uninitialized variables is causing a system (possibly a PS3 only system) to overwrite memory that doesn't belong to it. This gives us a pretty decent working hypothesis: The most likely explanation is that the bad system is overwriting the memory used by the other systems.Īll taken together. This indicates that a bad system is causing failures in multiple other systems. Could be uninitialized memory (can contain random data) or a thread timing issue.ĭifferent call stacks. This indicates that the bug depends on something random. This indicates that the bug might be in a PS3 specific system. Or the bug could be caused by uninitialized variables.

The bug could be timing related, making it disappear in slower debug builds.
AUTODESK INVENTOR TUTORIAL BUG CODE
It could be that some of the code that is stripped out in release builds protects against the bug. Instead be confident that everything you learn about the bug takes you one step closer to finding the cause.Īctually, the very things that make tricky bugs tricky already tells you some things about them: Don't get stressed out by the fact that you are not fixing the bug right now. Write down ideas of what might be causing the bug as you think of them and cross them out as you eliminate them. Take a sheet of paper and write down everything you know and don't know about the bug. Instead of focusing on fixing the bug, something you can't possibly do at this point, focus on finding out more about it. The more you learn, the less scary the bug will seem. The reason you feel that way is because you don't know anything about it. I recently dealt with a bug of this kind and here are my tips and tricks for bringing down such beasts: What can we do? Luckily, the situation is not as hopeless as it might seem. And there are only a few days left until submission. Squint against the searing rays of burning processor cycles and feel the warm wind of chassi fans fill the air with anticipation. Put on your camouflage vest and step out onto the hot motherboard plains.
