Though this may be in the humor category, here's what I was using most recently. I got it to run somewhat (so it may be a start). Here's what I did (on my Intel P4 Linux box): Start with a 5816 image and a new VM. Load Tim's VMMaker 3.7b1 Load this CS Open a Transcript find a small image with Morphic. In a Workspace: (InterpreterSimulatorLSB new openOn: 'small.image') test. I see the Morphic screen from small.image painted, but it doesn't keep running. I don't get any walkbacks; it just completes normally.

No, sorry; I just fixed that and didn't re-post.

Nah - while primitiveGetAttribute might well be wrong, that's not the
problem that's annoying me right now. I simply don't get notifiers that
should appear; put a self halt in the simulator and it simply exits, no
error handling, nothing. I've tried a 3.4 VM and that makes no
difference, so I doubt that it's a bug caused by the new VM I'm
running. The weird thing is that I can interrupt the simulator with no
problem and get the debugger, proceed, interrupt again and again.
No change in 5424 unfortunately. I'm getting quite annoyed with this.
Ned, if you put a 'self halt'in BitBltSimulation>initialiseModule does
it actually open a debugger for you? All I get is ... stop.

Well that's a relief - if I were getting different behaviour at that
level I'd be really pissed off.
Certainly there's some very odd stuff happening with errors.
Good news I can actually get a MVC image up in sim. Who knows
what tomorrow will bring?

Who knows > what tomorrow will bring? Fun fact: we get a debugger if we use #profileSends: instead of just #runForNBytes: Another fun fact: when you hit the halt the UIProcess gets killed off and restarted (this is of course why your loop stops). Try this: * put your halt in initialiseModule as before * open a ProcessBrowser, note the ID of the UI process * do this in a workspace: p := Processor activeProcess. sim test. "stops without a clue" * update the ProcessBrowser You will see the old activeProcess suspended in the list. Note that you can't debug it. Apparently the fork of the new UI process happens, but the debugger is not opening in it. Hmmm... try running the simulator from an MVC project. You get the debugger. Maybe something is referring to the uiProcess, ScheduledController, or some other global state and so is fooling the debugger into not opening correctly. -- Ned Konz http://bike-nomad.com/squeak/ |

Hi, Ned -

Well, Smalltalk started with humor ("Hey, wouldn't it be cool to send a message for every operation?..."), so I consider this to be a propitious start.
Seriously, though, Tim and I have both been sneaking up on a successful run. In fact, last night Tim opined that halfWordAt: was the problem. The two images I've tried get off in the weeds after loading other plugins such as balloon2D for corner rounding, Zip for decompression, and something else to find out if it's in a plugin (you have the same fix for this).
Anyway, please send me (only, unless someone else wants it) a zip with the small image and changes that you used. Then I can duplicate your work and set about getting my other images to work as well.
Thanks for your help. This is great progress.
Once reflection works, the only problem is figuring out where you want to go...
;-)
- Dan
PS to all: Tim and I will try to keep VMMaker up to date until we have things well checked out, and we'll send out little progress notes as we do.
PPS: I dropped the previous CCs because I think we're all on VMDev. Please let me know if this is not the case.

Yup. I saw that too. It was 'fixed' by making the module initialisation
for B2DPlugin not do the wrong thing; that was causing an error in the
bowels of the simulator >which was not raising a notifier< !
I'm currently convinced there is something seriously screwed in some
signal/exception code. Note that the unit test for exceptions fails the
'outer' related test. I also had a problem a while ago that I never
really got to the bottom of in VMMAker - an error would simply 'go by'
and make it look like the generation was done. We need to fix this PDQ
in my view.
I've been working with Dan on this and if you use mylatest VMMaker3-7b2
and the attached sim patch it should go a bit better. And since my
current bug seems to be to do with halfWordAt: it looks like Ned might
have fixed that... ta very much.
