stop workflow in race condition

Plugins & Plugin Development Alternate UI
#1

Without changing anything on my setup I found I could not load AltUI on my openluup pi.
Looking into this there seems to be a race condition in workflow 151

this goes on forever.
As the gui is not responding anymore, is there a way to disable workflow mode from the command line on my pi?
Any pointer is highly appreciated!

you need to debug the workflow
to disable workflows all together you need to set the variable"EnableWorkflows" of ALTUI device to 0, there must be a way to do this in openluup from the cmd line but not sure how.

I was lucky, the conditions stopped to fire and I was able to deactivate the workflow.
@amg0 would it be possible to find a way to detect race conditions and then automatically deactivate the rouge workflow? Would be a very useful feature.

The system should still be able to respond to HTTP requests, so the [tt]&id=setvariable[/tt] request should have been able to accomplish this.

Not needed now, though…

#5

Hello - looking for advice on how to set the variable “EnableWorkflows” via cmd line if possible? Also on openLuup

#6

Can you not just stop openLuup, open user_data.json in vi or nano, find the variable, and edit it? openLuup seems to keep user_data.json in “pretty” format, so it’s straightforward to edit its contents.

Great thanks - did the trick.
