PR #208478 added a lot of documentation about which packages were rebuilt in each stage of the stdenv bootstrap. However nothing checks that these comments agree with reality; they can bitrot over time. This PR rewrites those comments as assertions, so they cannot bitrot. This conversion did expose some ambiguity in our scheme for naming the stages. Suppose that `pkgs.stdenv.name=="stdenv-stage4", then which of these is "the stage4 coreutils"? ``` pkgs.coreutils pkgs.stdenv.__bootPackages.coreutils ``` The choice is arbitrary, and both choices have confusing corner cases. We should revisit this at some point.

# This file constructs the standard build environment for the
|
||
# Linux platform. It's completely pure; that is, it relies on no
|
||
# external (non-Nix) tools, such as /usr/bin/gcc, and it contains a C
|
||
# compiler and linker that do not search in default locations,
|
||
# ensuring purity of components produced by it.
|
||
#
|
||
# It starts from prebuilt seed bootstrapFiles and creates a series of
|
||
# nixpkgs instances (stages) to gradually rebuild stdenv, which
|
||
# is used to build all other packages (including the bootstrapFiles).
|
||
#
|
||
# Goals of the bootstrap process:
|
||
# 1. final stdenv must not reference any of the bootstrap files.
|
||
# 2. final stdenv must not contain any of the bootstrap files
|
||
# (the only current violation is libgcc_s.so in glibc).
|
||
# 3. final stdenv must not contain any of the files directly
|
||
# generated by the bootstrap code generators (assembler, linker,
|
||
# compiler). The only current violations are: libgcc_s.so in glibc,
|
||
# the lib{mpfr,mpc,gmp,isl} which are statically linked
|
||
# into the final gcc).
|
||
#
|
||
# These goals ensure that final packages and final stdenv are built
|
||
# exclusively using nixpkgs package definitions and don't depend
|
||
# on bootstrapTools (via direct references, inclusion
|
||
# of copied code, or code compiled directly by bootstrapTools).
|
||
#
|
||
# Stages are described below along with their definitions.
|
||
#
|
||
# Debugging stdenv dependency graph:
|
||
# An useful tool to explore dependencies across stages is to use
|
||
# '__bootPackages' attribute of 'stdenv. Examples of last 3 stages:
|
||
# - stdenv
|
||
# - stdenv.__bootPackages.stdenv
|
||
# - stdenv.__bootPackages.stdenv.__bootPackages.stdenv
|
||
# - ... and so on.
|
||
#
|
||
# To explore build-time dependencies in graphical form one can use
|
||
# the following:
|
||
# $ nix-store --query --graph $(nix-instantiate -A stdenv) |
|
||
# grep -P -v '[.]sh|[.]patch|bash|[.]tar' | # avoid clutter
|
||
# dot -Tsvg > stdenv-final.svg
|
||
#
|
||
# To find all the packages built by a particular stdenv instance:
|
||
# $ for stage in 0 1 2 3 4; do
|
||
# echo "stage${stage} used in:"
|
||
# nix-store --query --graph $(nix-instantiate -A stdenv) |
|
||
# grep -P ".*bootstrap-stage${stage}-stdenv.*->.*" |
|
||
# sed 's/"[0-9a-z]\{32\}-/"/g'
|
||
# done
|
||
#
|
||
# To verify which stdenv was used to build a given final package:
|
||
# $ nix-store --query --graph $(nix-instantiate -A stdenv) |
|
||
# grep -P -v '[.]sh|[.]patch|bash|[.]tar' |
|
||
# grep -P '.*stdenv.*->.*glibc-2'
|
||
# "...-bootstrap-stage2-stdenv-linux.drv" -> "...-glibc-2.35-224.drv";
|
||
#
|
||
# For a TUI (rather than CLI) view, you can use:
|
||
#
|
||
# $ nix-tree --derivation $(nix-instantiate -A stdenv)
