FS#76 - Povray returns incorrect exit code when aborting render
If you abort a render with ^C, Povray exits with a ‘success’ error code.
To test:
povray scene.ini (^C to abort it) echo $?
Right now 0 is returned (’success’). A non-zero value should be returned (’failure’).
This is particularly important for scripting, where command lines like:
povray scene.ini && halt
...can be used. I only want the halt to be executed if the scene renders successfully. If I change my mind and ^C it, I don’t want the machine to shut down!
Technically, it can be debated whether error code 0 is appropriate or not; as a matter of fact, when the render is aborted by the user, POV-Ray does not exit due to an error in the strict sense.
I think a sensible behaviour would be to pass on the SIGINT signal, which can then be trapped in the calling script. This is how 3.7 does it.
