• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Python function timeout

Hello everyone!

This time I need a little bit of special help - while programming my scripts.

First the affected part:
zwischenablage015qk5p.png


The problem is the following:
The function call in line 773 *might* take forever due to a small problem in a called module when the roads-shapefile is to big.
So i would like to start a timer, limited to i.e. 300 seconds. After these 300 seconds have passed, the script should go to the "except TimeoutError"-Part.
Then I can handle the problem, and re-run it.

Now I am running this script on windows and Python 2.7, so something like that
Code: 
signal.signal(signal.SIGALRM, handler)
... won't work.

I also tried it already with calling the multiprocessing-module, but it also doesn't really work.

Does anyone of you know, how I can add a timeout to the function call in line 773, which actively cancels the function calls inside ther erase_buffer_roads-function?

I kow, that this is a very special question, but maybe someone can help me!

Thanks in advance!
