If the nix store lives on NFS, ghc 8.2.1 is unable to build a package
database. This bug was fixed by @bgamari in ghc 8.2.2 here:
https://ghc.haskell.org/trac/ghc/ticket/13945

This commit upgrades the unpacked bootstrap GHC version, so that we can build
newer versions of GHC even if the store is on NFS.

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Fits CONTRIBUTING.md.

Sorry, something went wrong.

Note that this impacts users of GHC 8.2, 8.4, and 8.6 equally: all of them need the GHC 8.2-binary bootstrap compiler when building from src.

Without this, any build of any GHC fails (almost) immediately with this error, since the bootstrap compiler is unable to create package databases on NFS:

'/nix/store/7j7kci9f1h73pjcmy1vf2f7b60251npk-ghc-8.2.1-binary/lib/ghc-8.2.1/bin/ghc-pkg'
exited with an error:
ghc-pkg: Couldn't open database
/nix/store/7j7kci9f1h73pjcmy1vf2f7b60251npk-ghc-8.2.1-binary/lib/ghc-8.2.1/package.conf.d
for modification: {handle:
/nix/store/7j7kci9f1h73pjcmy1vf2f7b60251npk-ghc-8.2.1-binary/lib/ghc-8.2.1/package.conf.d/package.cache.lock}:
hLock: invalid argument (Bad file descriptor)
make[1]: *** [ghc.mk:993: install_packages] Error 1
make: *** [Makefile:51: install] Error 2

I verified that the ghc 8.2.2 binary does not have this problem.

If you like I could change line 20 at the same time, since this is going to cause a rebuild already.
