[Qgis-developer] Week 8 - report on "Multithread Support on QGIS Toolbox"

[Marcus Santos]

Thanks Victor!

Ok, I’ll do it later then. 
Maybe I’ll focus on a temporary fix I did in the multithread implementation. What do you suggest?

You may have noticed that I have a sleep after starting the worker thread. 
Without this sleep the QGIS crashes due to a segfault. I believe that the worker thread is trying to access something in the processing that no longer exists when the main thread leaves the processing. I can’t see exactly where it crashes because it is not easy to debug with multiple threads using Eclipse. I tried to use pyCharm but I was not able to configure the remote debugging.
It can take some time to figure out what is happening here.

Let me know if everything is ok with the single execution.

Cheers,
Marcus
