ee3220440d lib: implement compare, splitByAndCompare, and compareLists 2018-02-09 19:51:05 +00:00

Add setFunctionArgs lib function.
Among other things, this will allow *2nix tools to output plain data
while still being composable with the traditional
callPackage/.override interfaces.

Convert libs to a fixed-point
This does break the API of being able to import any lib file and get
its libs, however I'm not sure people did this.

I made this while exploring being able to swap out docFn with a stub
in #2305, to avoid functor performance problems. I don't know if that
is going to move forward (or if it is a problem or not,) but after
doing all this work figured I'd put it up anyway :)

Two notable advantages to this approach:

1. when a lib inherits another lib's functions, it doesn't
   automatically get put in to the scope of lib
2. when a lib implements a new obscure functions, it doesn't
   automatically get put in to the scope of lib

Using the test script (later in this commit) I got the following diff
on the API:

  + diff master fixed-lib
  11764a11765,11766
  > .types.defaultFunctor
  > .types.defaultTypeMerge
  11774a11777,11778
  > .types.isOptionType
  > .types.isType
  11781a11786
  > .types.mkOptionType
  11788a11794
  > .types.setType
  11795a11802
  > .types.types

This means that this commit _adds_ to the API, however I can't find a
way to fix these last remaining discrepancies. At least none are
_removed_.

Test script (run with nix-repl in the PATH):

  #!/bin/sh

  set -eux

  repl() {
      suff=${1:-}
      echo "(import ./lib)$suff" \
          | nix-repl 2>&1
  }

  attrs_to_check() {
      repl "${1:-}" \
          | tr ';'  $'\n' \
          | grep "\.\.\." \
          | cut -d' ' -f2 \
          | sed -e "s/^/${1:-}./" \
          | sort
  }

  summ() {
      repl "${1:-}" \
          | tr ' ' $'\n' \
          | sort \
          | uniq
  }

  deep_summ() {
      suff="${1:-}"
      depth="${2:-4}"
      depth=$((depth - 1))
      summ "$suff"

      for attr in $(attrs_to_check "$suff" | grep -v "types.types"); do
          if [ $depth -eq 0 ]; then
              summ "$attr" | sed -e "s/^/$attr./"
          else
              deep_summ "$attr" "$depth" | sed -e "s/^/$attr./"
          fi
      done
  }

  (
      cd nixpkgs

      #git add .
      #git commit -m "Auto-commit, sorry" || true
      git checkout fixed-lib
      deep_summ > ../fixed-lib
      git checkout master
      deep_summ > ../master
  )

  if diff master fixed-lib; then
      echo "SHALLOW MATCH!"
  fi

  (
      cd nixpkgs
      git checkout fixed-lib
      repl .types
  )

Excise use of importJSON
Putting information in external JSON files is IMHO not an improvement
over the idiomatic style of Nix expressions. The use of JSON doesn't
add anything over Nix expressions (in fact it removes expressive
power). And scattering package info over lots of little files makes
packages less readable over having the info in one file.

Remove fetchMD5warn
Deprecation warnings should not be used in Nixpkgs because they spam
innocent "nix-env -qa" users with (in this case) dozens of messages
that they can't do anything about.

This also reverts commit 2ca883338389b7ab995924a0cab0211993bdf1da.

nixos: make it easy to apply kernel patches
This makes it easy to specify kernel patches:

    boot.kernelPatches = [ pkgs.kernelPatches.ubuntu_fan_4_4 ];

To make the `boot.kernelPatches` option possible, this also makes it
easy to extend and/or modify the kernel packages within a linuxPackages
set. For example:

    pkgs.linuxPackages.extend (self: super: {
      kernel = super.kernel.override {
        kernelPatches = super.kernel.kernelPatches ++ [
          pkgs.kernelPatches.ubuntu_fan_4_4
        ];
      };
    });

Closes #15095

22d7c08dc5 lib.trivial: add a new importJSON function
This is meant to be used by packages who often re-generate their inputs.

Producing valid JSON is easier than nix, and also garantees it's purity.

4a91cfd32b Add a global variable ‘inNixShell’
This is primarily useful in Nix expressions that are also intended to
be used by nix-shell.  It allows saying things like:

  buildInputs = [ ... ] ++ (if inNixShell then [ emacs ] else [ ]);

This should not be used in Nixpkgs (since the question of what
constitutes a useful nix-shell environment is very subjective).
