9597 :: How to know if `--mm:arc` is applicable?

If my code is compiled and tested with --mm:orc with no problem, and if I don't use any module with async in name, or any object that can contain itself, then I can use ARC safely. Am I right?

Depending on your dependencies (or lack thereof): Yes.

And thanks for reminding me, orc could easily be used as a cycle detector but doesn't offer an API for that yet.

I have been meaning to make an RFC for that something like --nimEnsureAcyclic would make very many happy people :D

I vaguely remember compilation error messages when trying to create cycles and compiling with --mm:arc. What happened to those?

Araq (orginal) [2022-11-11T10:54:38+01:00] view original

The warning messages still exist but only capture a subset of problems. They are also not sound as in theory code that comes later could break up cycles manually via obj.field = nil.
