This change updates to the latest `nix-tools` to get the following fixes (there are 3 PRs in nix-tools, but just the one in haskell.nix to avoid having to update the materialized files multiple times):
## Better support for source repository packages
* https://github.com/input-output-hk/nix-tools/pull/107
Currently these are replaced by the `cabalProject` functions with regular `packages:` before running cabal configure. Cabal does not treat these the same (the setting of `tests:` and `benchmarks:` in the `cabal.project` file):
* The plan found by `cabalProject` may not match the one used when running `cabal`.
* The performance of the solver may not be consistent with running `cabal`.
This change replaces `source-repository-package` with another `source-repository-package` pointing at a minimal git repo.
## Only include planned components
* https://github.com/input-output-hk/nix-tools/pull/108
Only the components in the `plan.json` are now included in the haskell.nix cabal projects. This avoids missing dependencies attempting to build components that were not in the plan. Should fix#993.
## Pick latest packages
* https://github.com/input-output-hk/nix-tools/pull/109
When the same package occurs more than once in a `plan.json` file (perhaps because it is needed both by the project itself and by one of the `setup` dependencies or `build-tool-dependencies` of the project) the latest version will now be the one picked by haskell.nix. This is a work around for a common issue with `cabal-doctest` when cross compiling to windows (an old version of Win32 is used even if a newer one was required by the projects `constraints`).
The use of `sources.HTTP` to work around issues building GHC 9.0.1 causes a mismatch between `flake` based and non
`flake` based derivations.
The fixed version of HTTP is now in hackage so updating the internal hackage index state used haskell.nix removes the need for the HTTP source override.
See https://github.com/input-output-hk/nix-tools/pull/101
We should look up hsPkgs.${pkg-name}.components.exe.${component-name}
instead of including the package as a dependency.
Adding `hsPkgs.${pkg-name}` a tool it is not clear which executable in the package `haskell.nix` should choose.
Haskell.nix did not deal with this well and in fact it could lead to `nix-shell` crashing. For instance using `shellFor` to make a shell for building `haskell-language-server` with `cabal build` crashed as a dependency on `ghcide` the executable (by the `ghcide-bench` executable) caused infinite recursion. Allowing `ghcide-bench` to correctly depend just on `components.exes.ghcide` fixes this.
This PR also includes:
* Updated materialized files built with the new nix-tools and latest index-state
* Small update to GHCJS (pins happy) to fix issue that showed up when the materialization was updated
* A fix for the infinite recursion issue when updating materialized files (by adding ghc-boot-packages-unchecked).
* Performance fix for shellFor (checks just the names of component derivations when filtering).
Changes to the interface of haskell.nix (from the changelog.md file):
* Removed `sources.nixpkgs-default`, use `sources.nixpkgs` instead.
* Removed `./nixpkgs` directory, use `(import ./. {}).sources`
or `./nix/sources.nix` instead.
* Removes V1 interface for details on how to fix old code see:
https://github.com/input-output-hk/haskell.nix/issues/709
* Removed defaultCompilerNixName.
* cabalProject, cabalProject', hackage-project and hackage-package
now require a `compiler-nix-name` argument.
* `haskell-nix.tool` and `.tools` now require a `compiler-nix-name` argument.
New functions `p.tool` and `p.tools` (where p is a project) do not.
Like `shellFor { tools = ... }` they will use the compiler nix name
from the project (including stack projects where it is derived from
the resolver).
* `haskell-nix.alex` and `haskell-nix.happy` have been removed. Use
`p.tool "alex" "3.2.5"` or `shellFor { tools = { alex = "3.2.5"; } }`.
* `haskell-nix.nix-tools` -> `haskell-nix.nix-tools.ghc883` (it includes
the hpack exe now).
* `haskell-nix.cabal-install` ->
`p.tool "cabal" "3.2.0.0"` or `shellFor { tools = { cabal = "3.2.0.0"; } }`
* `haskell-nix.haskellNixRoots` -> `haskell-nix.roots ghc883` or `p.roots`
Other changes:
Adds hpack executable to the nix-tools derivations.
Adds a `cabal-hpack` test to make sure `hpack` works with
`cabalProject`.
Reduces the number of calls to `cabalProject` (particularly when
checking materialization), by giving internal tools a per-compiler
attribute.
Uses happy 1.19.12 when building newer ghc versions.
Updates cabal-install 3.2.0.0 to use the source from github that
is compatible with ghc 8.10.1.
Updates the docs for callCabalProjectToNix.
Adds a license mapping to fix a common warning.
* ghc 8.10
* Adds/Updates/Removes materialization files
* Disable one-shot-kqueue-on-macos patch on ghc-8.10
* Test ghc883 and ghc8101 but only with nix 20.03
* Various smaller fixes.
This should fix the infinite recursion issue with #654
