From 8d4aa2c15c88d6e2912882ebf480d89c172d4e1f Mon Sep 17 00:00:00 2001 From: Adam Joseph Date: Mon, 11 Dec 2023 23:34:47 -0800 Subject: fix(tvix/eval): add unimplemented __curPos and builtins.filterSource This commit adds __curPos (to the global scope, yuck) and builtins.filterSource. These are not implemented; forcing them will produce the same result as `throw "message"`. Unfortunately these two post-2.3 features are used throughout nixpkgs. Since an unresolved indentifier is a catchable error, this breaks the entire release eval. With this commit, it simply causes those broken packages that use these features to appear as they are: broken.
