2023-12-01	Put functional tests in `tests/functional`	John Ericson
	I think it is bad for these reasons when `tests/` contains a mix of functional and integration tests - Concepts is harder to understand, the documentation makes a good unit vs functional vs integration distinction, but when the integration tests are just two subdirs within `tests/` this is not clear. - Source filtering in the `flake.nix` is more complex. We need to filter out some of the dirs from `tests/`, rather than simply pick the dirs we want and take all of them. This is a good sign the structure of what we are trying to do is not matching the structure of the files. With this change we have a clean: ```shell-session $ git show 'HEAD:tests' tree HEAD:tests functional/ installer/ nixos/ ``` (cherry picked from commit 68c81c737571794f7246db53fb4774e94fcf4b7e)
2022-01-03	add zipAttrsWith primop	pennae
	nixpkgs can save a good bit of eval memory with this primop. zipAttrsWith is used quite a bit around nixpkgs (eg in the form of recursiveUpdate), but the most costly application for this primop is in the module system. it improves the implementation of zipAttrsWith from nixpkgs by not checking an attribute multiple times if it occurs more than once in the input list, allocates less values and set elements, and just avoids many a temporary object in general. nixpkgs has a more generic version of this operation, zipAttrsWithNames, but this version is only used once so isn't suitable for being the base of a new primop. if it were to be used more we should add a second primop instead.
