Originally created by @ixje on GitHub (Nov 12, 2024).

I'm always frustrated when breakpoints set for a given prog (=smart contract) don't hit because they are registered for the current context and not globally for the smart contract.

Describe the solution you'd like

I'd like an AddBreakPoint on VM which allows to set a global breakpoint for a given contract (similar to the C# one).

Describe alternatives you've considered

Create AddBreakpoint / RemoveBreakPoint on Context.

Additional context

Imagine an IDE with NEO smart contract debugger support build on neo-go. The IDE tells what addresses to put a break point on, then runs the debugger waiting for a break point to hit. Currently it won't hit any break points except for those in the entry function.

If you're fine with the following rough approach I'm happy to PR for it

func AddBreakPoint(h uint160, addr int) {
   for ctx in vm.istack {
      if h == ctx.scriptHash {
          ctx.breakpoints.add(addr)
      }
}

and similar logic for a RemoveBreakPoint
