From 162e21f2bb326960770ed55ee44170b924c72fd8 Mon Sep 17 00:00:00 2001 From: sterni Date: Mon, 12 Sep 2022 18:03:43 +0200 Subject: fix(tvix/eval): force left argument of `?` before checking for attrs OpAttrsIsSet and OpAttrsTrySelect will fail silently if the attribute set value on the stack is actually a thunk, so we need to make sure to force at every step of the way. Emitting the force instructions in the compiler because it is easier to add, but maybe the VM should do this when handling the relevant opcodes? Comments welcome.
