Test runner does not handle stack overflow correctly #63

Closed bitfield closed 2 years ago

bitfield commented 2 years ago

Solution ec84829229e74e1da9828f67823637c9 to 'Tree Building' is not correct, but the test runner shows a pass. Running the tests on my machine produces:

Hi @bitfield

Can you post the code of the solution that gives that result here please? I don't think we can access it just with the uuid.

junedev commented 2 years ago

@andrerfcsantos I guessed the URL: https://exercism.org/tracks/go/exercises/tree-building/solutions/ec84829229e74e1da9828f67823637c9

bitfield commented 2 years ago

Thanks! I don't know how to get that URL from the exercise itself. Is there an easy way?

junedev commented 2 years ago

@bitfield I don't think there is any way to get this URL from the mentoring screen and building the URL like I did above probably only works when the student actually published the solution. So the best way to report an issue would be to include the solution in the issue description in the future. There is a copy button next to the download button in the mentoring screen.

junedev commented 2 years ago

I investigated this. Normal recoverable panics are handled just fine but this is a fatal runtime error because of the stack overflow. That is not handled correctly by the test runner. I fixed this now.
