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. |

Nix
Nix is a powerful package manager for Linux and other Unix systems that makes package management reliable and reproducible. Please refer to the Nix manual for more details.
Installation
On Linux and macOS the easiest way to install Nix is to run the following shell command (as a user other than root):
$ curl -L https://nixos.org/nix/install | sh
Information on additional installation methods is available on the Nix download page.
Building And Developing
See our Hacking guide in our manual for instruction on how to build nix from source with nix-build or how to get a development environment.
