2022-01-03add zipAttrsWith primoppennae
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.

2021-12-02Fix docker commandDavid Purdum
`docker -ti run nixos` does not run on docker version 20.10.7 (my machine). This fixes it to read `docker run -ti nixos`.
2021-12-02Introduce builtins.groupBy primopSilvan Mosberger
This function is very useful in nixpkgs, but its implementation in Nix itself is rather slow due to it requiring a lot of attribute set and list appends.
2021-12-01reproducibility: hide non-reproducible settings from manualArthur Gautier
Because the manual is generated from default values which are themselves generated from various sources (cpuid, bios settings (kvm), number of cores). This commit hides non-reproducible settings from the manual output.

This is in line with XDG Base Directory Specification, where ~/.config is supposed to be used when XDG_CONFIG_HOME is unset. It also better matches the reality, where ~/.config/nix.conf does not seem to be used.
