This removes a dynamic stack allocation, making the derivation unparsing logic robust against overflows when large strings are added to a derivation. Overflow behavior depends on the platform and stack configuration. For instance, x86_64-linux/glibc behaves as (somewhat) expected: $ (ulimit -s 20000; nix-instantiate tests/lang/eval-okay-big-derivation-attr.nix) error: stack overflow (possible infinite recursion) $ (ulimit -s 40000; nix-instantiate tests/lang/eval-okay-big-derivation-attr.nix) error: expression does not evaluate to a derivation (or a set or list of those) However, on aarch64-darwin: $ nix-instantiate big-attr.nix ~ zsh: segmentation fault nix-instantiate big-attr.nix This indicates a slight flaw in the single stack protection page approach that is not encountered with normal stack frames. |
