hackage2nix: Split configuration, auto disable hydra builds We split configuration-hackage2nix.yaml into multiple files. We bump cabal2nix-unstable to get support for multiple config files in hackage2nix. * The file main.yaml is only supposed to be edited by humans. * The file stackage.yaml is only supposed to be updated by the update-stackage.sh * The file broken.yaml can be edited by humans, but probably future helpers will want to insert broken packages into this file based on hydra reports. * The file transitive-broken.yaml is newly introduced to be generated by regenerate-transitive-broken-packages.sh regenerate-transitive-broken-packages.sh makes a nix query (in transitive-broken-packages.nix) which evaluates all haskellPackages once with and once without "allowBroken" this way it get's a list of packages which are broken by some transitive dependency, but does not disable packages which have eval errors not caused by a broken package. 2021-05-05 22:38:46 +02:00			`let`

maintainers/scripts/haskell: fix regenerate-transitive-broken - use `restrict-eval` so that we're not affected by the user's environment - use jq instead of the horrible echo+sed hack The second point also fixes the indentation before each line to be two spaces instead of one, so I set it back to one space to avoid a diff. 2022-12-24 11:02:15 +01:00			`${lib.concatMapStringsSep "\n" (x: " - ${x}") brokenDeps}`
