lib: trivial spelling fixes

# snippets that can be shared by multiple fetchers (pkgs/build-support)
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 )

lib/fetchers.nix: factor out impure proxy vars (#18702) Apparently everyone just copied those variables, instead of creating a library constant for them. Some even removed the comment. -.-

lib.fetchers: Add uppercase proxy environment variables The [Nix installer](https://github.com/NixOS/nix/blob/84e0c464f11b34fa7d5ca26dcf98a91c4d596d59/scripts/install-systemd-multi-user.sh#L38) and the [documentation](https://github.com/NixOS/nix/blob/84e0c464f11b34fa7d5ca26dcf98a91c4d596d59/doc/manual/src/installation/env-variables.md#L54-L56) state that they support uppercase proxy environment variables. [lib/fetchers.nix](https://github.com/NixOS/nixpkgs/blob/165090ed665fd56e1cabc4e2ac3b3b5524596a6a/lib/fetchers.nix#L10) only supports lowercase proxy environment variables. Fix: [nix#10491](https://github.com/NixOS/nix/issues/10491)
