- Added the ability to generate coverage reports for packages and
projects.
- Outputs mix and tix information, as well as a HTML report.
- Added the "doCoverage" module option that allows users to choose
packages to enable coverage for.
- Added a "doCoverage" flag to the component builder that outputs HPC
information when coverage is enabled.
- Added the "overrideModules" library function to make it more
ergonomic fo users to enable coverage on existing projects.
- Modified the "check" builder to also output ".tix" files (if they
exist). This information is required to generate the coverage
report.
- Added a test for coverage.
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.
Now that the defaultCompilerNixName is used to choose which GHC to use
for tools we need to update haskellNixRoots to make sure the common
tools wind up in the cache.
To do this we add the compilerNixName as a dimension in ci.nix.
This has the added bonus of ensuring the tests a run with the
supported versions of ghc (not just the default one).
haskellNixRoots is also updated to include the tools built with the
defaultCompilerNixName (in particular cabal-install was not pinned
and this was the likely cause of significant builds due to cache
misses).
* Include `tests` in path for cross compiled tests
* Add ghc-boot-packages-nix to haskellNixRoots
* Fix naming warnings in tests sources
* Uses a single cleanGit call for all the tests
* Add memoize code for ghc-boot and ghc-extra pkgs
* Memoize ghc-boot and ghc-extra pkgs nix
* Fix release.nix being more strict than ci.nix by updating filterAttrsOnlyRecursive in ci-lib.nix
* Nicer errors when materialized path does not exist
* Updated materialization docs
* Add internalHackageIndexState to set the index-state used within haskell.nix
I found that if I added this to my stack.yaml:
ghc-options:
$locals: -ddump-to-file -ddump-hi
As specified in https://docs.haskellstack.org/en/stable/yaml_configuration/#ghc-options
Then my build would fail to evaluate with:
error: The option `packages."\$locals".package.identifier.name' is used but not defined.
So to fix it, we filter out these special package globs in mkStackPkgSet.
This commit also adds a regression test for that configuration option.
This change replaces `passthru.run` and `collectRunComponents` with
`haskellLib.check` and `$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.
