[Jprogramming] [Jgeneral] Report of the J Wiki Group Zoom Meeting of July 7, 2022

[Raul Miller]

Eh... and I still managed to get it wrong, here...

Maybe setting stops gave that behavior, but reviewing
https://github.com/jsoftware/j-playground/issues/31 I see that it was
stopping from an error (as opposed to an explicit stop -- I don't know
if those were ever enabled).

We can still lock up a playground window using that script...

On the plus side, having the popup loop still active means that it
should be possible to debug it.

More specifically, emj.wasm 0x0122fa5 (a call_indirect with a bunch of
parameters which might be zeros) is what triggers the popup. So if we
could figure out what that corresponds to in the C source, that's what
we would have to change to fix this problem.

I'll drop a quick note into that github issue...

FYI,

And, attempting to close that javascript popup would bring it back up again. So there was no way to regain control of that browser session -- you had to close the window. More recently, setting stops seems to have been completely disabled in the playground.
