This fixes #126344, specifically with the goal of enabling overriding the checkPhase argument. See `design notes` at the end for details. This allows among other things, enabling bash extension for the `checkPhase`. Previously using such bash extensions was prohibited by the `writeShellScript` code because there was no way to enable the extension in the checker. As an example: ```nix (writeShellScript "foo" '' shopt -s extglob echo @(foo|bar) '').overrideAttrs (old: { checkPhase = '' # use subshell to preserve outer environment ( export BASHOPTS shopt -s extglob ${old.checkPhase} ) ''; }) ``` This commit also adds tests for this feature to `pkgs/tests/default.nix`, under `trivial-overriding`. The test code is located at `pkgs/build-support/trivial-builders/test-overriding.nix`. Design notes: ------------- Per discussion with @sternenseemann, the original approach of just wrapping `writeTextFile` in `makeOverridable` had the issue that combined with `callPackage` in the following form, would shadow the `.override` attribute of the `writeTextFile`: ```nix with import <nixpkgs>; callPackage ({writeShellScript}: writeShellScript "foo" "echo foo") ``` A better approach can be seen in this commit, where `checkPhase` is moved from an argument of `writeTextFile`, which is substituted into `buildCommand`, into an `mkDerivation` argument, which is substituted from the environment and `eval`-ed. (see the source) This way we can simple use `.overideAttrs` as usual, and this also makes `checkPhase` a bit more conformant to `mkDerivation` naming, with respect to phases generally being overridable attrs.
