CI as debugging aid?
Locked
 
|
It just occurred to me that we could possibly use CI jobs as a means
of debugging naughty plugins. Recall that we had LargePositiveInteger test failures crashing the VM (http://squeakci.org/job/SqueakTrunk/67/console for instance)? If we ran a full test suite on a VM with debugging support, we could gain some insight into this particular, intermittent, problem. Once 4.4's out the door, we'd just need to get our hands on a debugging VM. If Eliot built one as part of his usual publishing routine, we could just use that... *cough*. frank |

If you are thinking of the assert-enabled Cog that Eliot describes here: http://lists.squeakfoundation.org/pipermail/squeak-dev/2012-December/166750.html You can probably just use the one that Eliot provided. I expect that this is just a matter of setting a couple of flags in the configuration step of building Cog, so you (we) can probably do this easily on the squeakci.org server to make your own debugging VM. We'll need to confirm which flags to set of course. I'm not sure how useful this would be, but it can't hurt to try it. Next April 1, I think I'll release my SUnit enhancements to provide support for "self shouldnt: #crash" in unit tests ;-) Dave |

Yes, those are the VMs I mean.

I think there was some noise around setting up builds to test the Cog VMs anyway, on vm-dev, wasn't there? > I'm not sure how useful this would be, but it can't hurt to try it. > > Next April 1, I think I'll release my SUnit enhancements to provide > support for "self shouldnt: #crash" in unit tests ;-) :) frank > Dave > |

So if you need a locally-built VM on that squeakci server with some specific configuration (such as debugging support), you can easily tweak that test build to produce whatever you want. But to be clear: These are *not* VMs that are intended for distribution, and nobody should use them as a replacement for the official distributions on Eliot's site. Likewise, there is an automated build of the standard interpreter VM at http://squeakci.org/job/InterpreterVM/ that does a VM build to check source integrity, and these are *not* a replacement for Ian's official distributions at http://squeakvm.org/unix/.
