Partition all-cabal-hashes into case-insensitive-safe components. OS X by default has a case-insensitive filesystem, and fetching all-cabal-hashes there fails due to a hash mismatch caused by package pairs like compactable and Compactable. This partitions the package set such that each partition contains no equivalent-up-to-case pairs. 2017-10-10 17:24:30 +01:00			`{ fetchFromGitHub`

callHackage: make 'all-cabal-hashes' repository overridable This commit changes callHackage to use a deterministic version of the Hackage checkout from https://github.com/commercialhaskell/all-cabal-hashes by default. This means that packages uploaded to Hackage after today will be available to callHackage only after "pkgs/data/misc/hackage/default.nix" has been updated. People who want the previous behavior where we always had the latest version of Hackage available -- at the cost of frequent downloads from Github --, can add the following override to their "~/.nixpkgs/config.nix" file: { packageOverrides = super: { all-cabal-hashes = builtins.fetchTarball "https://github.com/commercialhaskell/all-cabal-hashes/archive/hackage.tar.gz"; }; } 2016-11-01 17:29:43 +00:00
