This patch adds `lib.repoRevToName` function that generalizes away most of the code used for derivation name generation by `fetch*` functions (`fetchzip`, `fetchFromGitHub`, etc, except those which are delayed until latter commits for mass-rebuild reasons). It's first argument controls how the resulting name will look (see below). Since `lib` has no equivalent of Nixpkgs' `config`, this patch adds `config.fetchedSourceNameDefault` option to Nixpkgs and then re-exposes `lib.repoRevToName config.fetchedSourceNameDefault` expression as `pkgs.repoRevToNameMaybe` which is then used in `fetch*` derivations. The result is that different values of `config.fetchedSourceNameDefault` now control how the `src` derivations produced by `fetch*` functions are to be named, e.g.: - `fetchedSourceNameDefault = "source"` (the default): ``` $ nix-instantiate -A fuse.src /nix/store/<hash>-source.drv ``` - `fetchedSourceNameDefault = "versioned"`: ``` $ nix-instantiate -A fuse.src /nix/store/<hash>-libfuse-2.9.9-source.drv ``` - `fetchedSourceNameDefault = "full"`: ``` $ nix-instantiate -A fuse.src /nix/store/<hash>-libfuse-2.9.9-github-source.drv ``` See the documentation of `config.fetchedSourceNameDefault` for more info.
