Julia: ctrl+c does not interrupt

Question

I'm using REPL inside VScode and trying to fix a code that gets stuck inside a certain package. I want to figure out which process is taking time by looking at the stack trace but cannot interrupt because REPL does not respond to ctrl+c. I pressed ctrl+x by accident and that showed ^X on the screen.

I am using JuMP and GLPK so it could be stuck there. However, I am not seeing any outputs.

I would also appreciate any tips on figuring out which process is causing it to be stuck.

Answer 1

Interrupts are not implemented in GLPK.jl. I've opened an issue: https://github.com/jump-dev/GLPK.jl/issues/171 (but it's unlikely to get fixed quickly).

If you're interested in contributing to JuMP, it's a good issue to get started with. You could look at the Gurobi.jl code for how we handle interrupts there as inspiration.
