* Include dependencies of haskell.nix that were tracked in `nix/sources.json`
as flake inputs (`flake.lock` replaces `nix/sources.json`).
* Use `flake-compat` to continue to provide a compatible interface for non
flake projects.

Fixes:
Warning: `stdenv.lib` is deprecated and will be removed in the next release. Please use `pkgs.lib` instead. For more information see https://github.com/NixOS/nixpkgs/issues/108938
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.
Adding materialize call to a derivation should not prevent nix form
building it concurrently with other derivations.
This test makes sure that is the case.
Now that we are enumerating ghc versions in ci.nix we do not need
to do it in build.nix. Also adds ghcide 0.2.0 so it will be cahced.
ghcide-object-code is disabled on ghc 8.10.1
Changing from absolute links to relative links increases the length of
the parameters passed during linking by half. For things that have many
dependencies, this results in linking failing with an "argument list too
long" error.
Fixes#562
This change also updates the CI configuration files to help make
it easier for CI to cope with this sort of change.

This overlay helps accessing common executable components.
Typically we want to make these available in a nix-shell
created with shellFor. In most cases the package name
will be the same as the executable, but we have a
`toolPackageName` mapping to help when it is not.
```
# To get a single tool:
haskell-nix.tool "cabal" "3.2.0.0"
# This does the same thing as:
(haskell-nix.hackage-package {
name = "cabal-install"
version = "3.2.0.0"
}).components.exes.cabal
# To get an attr set containing multiple tools:
haskell-nix.tools { cabal = "3.2.0.0"; hlint = "2.2.11"; }
# To add tools to a shell:
shellFor { tools = { cabal = "3.2.0.0"; hlint = "2.2.11"; }; }
```
When used in shellFor the tools will be compiled with the same version
of ghc used in the shell (the build ghc in the case of cross
compilation).
Instead of a version string we can use an attr set containing
arguments that will be passed to `cabalProject`.
For instance to specify the ghc used to compile. Use:
```
haskell-nix.tool "cabal" {
version = "3.2.0.0";
ghc = haskell-nix.compiler.ghc883;
}
```
* Update nixpkgs pins to include 20.03, wobble
- Add 20.03
- Remove 19.03 (and old 18.09 file)
- Update 19.09 to latest
- Update github pin to 20.03
- Remove workarounds for 19.03
* Mark openssl as allowedInsecure
* Force python3 for mkdocs
* Remove unused (and broken) test files
* Make default.nix expose pinned nixpkgs
Also make `nixpkgs/default.nix` just an attribute set of sources.
This is simpler, and consistent with what e.g. `niv` does.
* Add backwards compatibility shim, and version argument to allow evolution in future
* Fix some missed things
* Fix and improve quickstart
* Define release.nix in terms of ci.nix
Beef up ci.nix to handle the same things as release.nix, then implement
the one in terms of the other.
* Fix infinite loop in evaluating release.nix with high ifdLevel
* Add tests to cross-compile
* Remove obsolete fix
* Do generic platform filtering
* Undefined variable
* Extract ci-lib.nix
* More undefined variables
* Use filterAttrsOnlyRecursive to avoid forcing all the drv attributes
* Set ifdLevel 0 to see if it fixes hydra eval
* Turn off tests on aarch64 cross
* Ifd level 1
* Ifd level 2
* Ifd level 3
* Maybe it's required that's too big?

This change replaces `passthru.run` and `collectRunComponents` with
`haskellLib.check` and `$pkg.checks`.
Uses `ln -s` instead of `cp` for DLLs to avoid duplicating them.
Adds features to help debugging eval issues with haskell.nix/release.nix.
The ifdInputLevel can be set to limit the jobs included to control
how much work is done at the eval stage when looking for issues.
Reduce CI times by excluding older ghc versions from haskellNixRoots
(GHC 8.6.3 and 8.6.4)
Sets `preferLocalBuild=false` on `callCabalProjectToNix` and `callStackToNix`
to ensure they are cached on hydra for both Linux and macOS.
Fix `data-dir:` when cleaning components.
`normalizeRelativeDir` adds a slash on to the end of `dataDir`.
Adding another one here results in `//` and files are left out by
mistake.
Changes to the haskell.nix code to fix broken tests:
* Add missing `then` to `call-cabal-project-to-nix.nix`.
* Fix default `hsSourceDirs` so that `.` gets included for `.all` component if one of the components does not have a `hsSourceDir` set.
* Fix `haskellNixRoots` so it works when cross compiling to windows.
Improvements to the haskell.nix tests:
* Run haskell.nix tests of nixpkgs 19.03 and 19.09.
* Run haskell.nix tests cross compiled to Windows under Wine (when possible).
* Add nix used as IFD inputs as tests to ensure they are cached.
* Use `haskell-nix.cabal-install` instead of `nixpkgs.cabal-install` in tests.
Projects like asterius and leksah that include dependencies on ghc. Sometimes the are needed by a setup.hs file (as is the case for the binaryen package used by asterius). The recent overlays merge broke this and #279 was needed to allow reinstallableLibGhc to be used to fix it. This PR adds a test case to make sure it is not inadvertently broken again. Also gives us a place to try out better ways to make this type of package work.* Test setup deps issue depending on ghc and Cabal
* Uses nixpkgs 19.09 + macOS wine fix on hydra/buildkite
* Enables macOS hydra tests
* disables musl tests for now
* Adds haskellNixRoots to tests
* Uses reinstallableLibGhc to fix the new setup-depends test
* Adds meta.platforms to haskell.nix components
* Set meta.platforms on cabal-install
* Builds some maintainer-scripts on hydra
* Pins hackage index-state for ghc-extra-packages
The Overlays branch
This is a major reorganization in how haskell.nix is used, and marks our 1.0 release.
The branch doesn't build due to numerous issues that we believe to be with the CI
and not this branch. We expect only very minor adjustments prior to calling this the
official 1.0 release.
* Move iohk-nix patches into haskell.nix
This moves the customizations we did in iohk-nix
into haskell.nix via overlays and config.
Add bootPkgs logic
this moves the nuking of bootPkgs where it belongs. This should eventually still be
removed and replaced by a proper solution, that doesn't require the nuking of
bootPkgs.
Allow us to bootstrap binary ghcs and a cabal-install
With this we can do the following:
```
$ nix repl compiler/old-ghc-nix
nix-repl> :b (let pkgs = import <nixpkgs> {}; in with import ./. {}; import ./compiler/bootstrap/cabal-install.nix { inherit (pkgs) fetchurl stdenv zlib; inherit hackage
; ghc = ghc844; src = pkgs.fetchurl { url = "https://github.com/haskell/cabal/archive/Cabal-v3.0.0.0-rc3.tar.gz"; sha256 = "1zl2mgg8307ykq3v8nmafc6zdhhj1cw7w8ffpap16dsm6
5lbnx33"; }; })
```
which wile it may look daunting, will allow us to bootstrap a
cabal-install with a ghc. From that point onwards, we should be able to
build any hackage package via haskell.nix.
Pass through cabal-install version
Better threading of arguments.
Add bootstrap overlay
Allow alex + happy to be built
This still has a wart: we need nix-tools, and for that we use the ghc865 from
nixpkgs. Ideally we'd build nix-tools against a specific ghc, but then
we'd need a build expression for that.
Make ghcjs work
Building something like this:
```
nix build '(with import ./. { nixpkgs = ../nixpkgs; nixpkgsArgs = { crossSystem = { config = "js-unknown-ghcjs"; }; }; }; (haskell-nix.hackage-package { name = "hello"; version = "1.0.0.2"; })).components.exes.hello'
```
will now work. Assuming `nixpkgs` has been appropriately patched to support the `js-unknown-ghcjs` triple.
Also: this will need an additional `Cabal` patch, to make `Cabal` understand what it needs to do with: `dist/build/hello/hello: copyFile: does not exist (No such file or directory)`
It needs to learn that `dist/build/hello/hello.jsexe` is what it wants to copy and that that is a directory. Luckily we do have some code in Cabal already that does this for `.exe` on windows.
Build `js-unknown-ghcjs` packages with haskell.nix
Using the following expression:
```
with import ./. { nixpkgs = ../nixpkgs; nixpkgsArgs = { crossSystem = { config = "js-unknown-ghcjs"; }; }; };
let Cabal = buildPackages.haskell-nix.hackage-package {
name = "Cabal"; version = "2.4.1.0";
modules = [
{ packages.Cabal.patches = [ ./Cabal-install-folder.diff ]; }
];
}; in
(haskell-nix.hackage-package {
name = "hello"; version = "1.0.0.2";
modules = [
({config, ... }:{ packages.hello.package.setup-depends = [ Cabal ]; })
];}).components.exes.hello
```
in a `test.nix` file. And running
```
nix build -f ./test.nix
```
on it, will produce
```

* Buildkite: Add a test for nix-tools closure size
The limit is a rather generous 500MB.
* nix-tools: Reduce closure size
1. Run justStackExecutables on hpack to remove dependency on ghc and
libraries.
Ideally we would be using the component builder on hpack.
2. Replace nix-prefetch-scripts with nix-prefetch-git. stack.yaml
supports mercurial repositories but I've never seen it used.
