Is this just my impression? Do we know if there are still open issues with the FFI in this area?

I’m glad some things has been covered, but as much as I would like to declare FFI work finished, I’m still working on it and I will spend a lot more time on stabilising (for example, I’m still having crashings in Johan’s work… crashes that are FFI related… some problem when copying bits to world surface that I bet can affect roassal2 too)

But well… we are a lot better now than 2 weeks ago :)

Excellent. Esteban I also got the bug mentioned by Johan. Now should we update to the latest vm?

may be playing with OSWindow will find some bugs. Did you check the SDL20 examples because they were failing?

I still do not start SDL migration (it shouldn’t be difficult). Probably this week, if I find the time :)

Hi,

With the latest development, Roassal2 seems to work well.

For example, the rendering of the logical view of Glamour browsers was broken, and now it works well. This is great news.

If Esteban says there are problems, there are problems. (And he did say so.)

yep… but since is like a “side effect fix” I wouldn’t be surprised if it is still there (and I just did not managed to produce the crash :( )

anyway, good luck :)

Thanks for pointing me to the right VM!

But indeed, it still crashes on a GrafPort>copyBits call when drawing a TRMorp. So if you are using Roassal2, Pharo will crash on you at some point. :-(

is weird.

load and run: crash. load, save&quit, open and run: not crash

at least in my environment.

Sounds familiar

Yes that seems the case here too, I have tick and tock moving around the screen for some hours now without any issues. Stef, those are *states*, not robots. Your mail really confused me, I thought you had robot hardware at RMOD !!

May be a garbage collect related issue, as saving triggers a GC, no ?

Stephan, why do you say this sounds familiar?

So I guess I was too happy too fast. The image that did not crash, in the end does crash after some time. I used it to do some LRP development and it just died on me with the usual segfault on GrafPort>copyBits :-(

So this still needs to be handled …

Can you provide a script that crashes it from a fresh Image (including loading Roassal2) ? So I try to can report additional observations.

Sure that’s easy: install LRP from here http://pleiad.cl/LRP and run the first example program on that page. Have a look at the page to see how to do that ;-)

To install you can get the pre-built image from https://ci.inria.fr/pharo-contribution/job/LiveRobotProgramming/

Or:

Gofer it smalltalkhubUser: 'jfabry' project: 'LiveRobotProgramming'; configuration; loadDevelopment

Run this code:

(machine esc (state tick) (state tock) (ontime 500 tick -> tock) (ontime 500 tock -> tick) )

And wait.
