treewide: refactor `.attrs.sh` detection When specifying the `builder` attribute in `stdenv.mkDerivation`, this will be effectively transformed into builtins.derivation { builder = stdenv.shell; args = [ "-e" builder ]; } This also means that `default-builder.sh` is never sourced and as a result it's not guaranteed that `$NIX_ATTRS_SH_FILE` is set to a correct location[1]. Also, we need to source `.attrs.sh` to source `$stdenv`. So, the following is done now: * If `$NIX_ATTRS_SH_FILE` points to a correct location, then use it. Directly using `.attrs.sh` is problematic for `nix-shell(1)` usage (see previous commit for more context), so prefer the environment variable if possible. * Otherwise, if `.attrs.sh` exists, then use it. See [1] for when this can happen. * If neither applies, it can be assumed that `__structuredAttrs` is turned off and thus nothing needs to be done. [1] It's possible that it doesn't exist at all - in case of Nix 2.3 or it can point to a wrong location on older Nix versions with a bug in `__structuredAttrs`. 2023-09-28 13:09:26 +00:00			`if [ -e "$NIX_ATTRS_SH_FILE" ]; then .

build-support: Add fetchfossil function. This is a dead-simple fetcher which clones a Fossil repository, opens it directly into $out, and then nicks out the single Fossil checkout marker. 2016-08-19 05:29:30 +00:00			`source $stdenv/setup`
