Without some distinct identifier, downloaded sources will accumulate (and have been since the last time the datestamp was updated). The old caches are ignored and will be purged according to GitHub's cache expiration, because otherwise we'd continue to carry 4 years' worth of outdated source tarballs.
When a non-library component has unfilled Backpack signature requirements, the error message now shows where each requirement came from (e.g. "brought into scope by build-depends: Fail1") using the ModuleSource information already available in the ModuleScope. Updated the Fail3 test golden files and strengthened the test assertion to verify provenance information is present. Addresses haskell#7192 run fourmalou more formatting
- Follow hlint suggestion: use replicateM_ - Follow hlint suggestion: functor law - Follow hlint suggestion: use flip - Satisfy fourmolu
Remove commented-out `planPkgOf` function from `SolverInstallPlan`.
Handle removing files better
HLint monoid laws, functor law and replicateM_
It has backward compatibility, but tagged as `DEPRECATED`, and we build tests with `-Werror=deprecations`.
update IntegrationTests2 for tasty-1.5.4
The primary entrypoint is now `make bootstrap-jsons`, which is now documented and called out in `bootstrap/README.md`. It automatically tries to obtain ghc versions from first `ghcup`, falls back to Nix if `nix-shell` is found, and if all else fails warns the user to install the appropriate ghcs. The Nix script can still be used directly, but now obtains the list of ghc versions from the `Makefile`.
- Format ghc-supported-languages module - Add an args check with help - All extensions should be registered - Exclude known languages - Rename exceptions to langsAsExts - Rename executable to ghc-supported-extensions - Use explicit import lists, except for prelude - Don't use dieNoVerbosity - Move to exes/GhcSupportedExtensions.hs - Handle the zero args case gracefully - Satisfy fourmolu - We're checking KnownExtension - Avoid _ in registered pattern match - Mention language editions - Add a note about missing language editions
available targets are only host
Isolate the common logic between building and only downloading. _Push the ifs up and the loops down_

Determine packages to build in-place by their solver id, not their package id.
Cabal uses a peculiar c program to check if LD supports and should use -x. To do this, it shells out to GHC to compiler the C file. This however requires that GHC will not bail out, yet cabal does not pass --package-db flags to this GHC invocation, and as such we can run into situations where GHC bails out, especially during GHC bootstrap phases where not all boot packages are available. We however do not need GHC to compiler a c program, and can rely on the C compiler. Fundamentally cabal does not allow modelling program dependencies in the program db, as such we must configure gcc first before using it. We make a small change to lib:Cabal (specifically the GHC module, and it's Internal companion) to allow it to configure gcc first, before trying to configure ld, and thus having gcc in scope while configuring ld. This removes the need for the awkward ghc invocation to compiler the test program.
Split the function into multiple ones.
If a node has dangling edges, then the list of missing neighbours cannot be empty.
Exceptions are not nice but this is an obvious invariant. Graph should provide a better API to make this unnecessary.
Not really a fix. I do not know why this happens.
It is duplicate information since we write the program invocation right after.
This is a partial revert of f47840d GHC toggles -dyanmic-too for TH and now we're missing shared interface files.
…r usage Adds a test package with a Custom Setup.hs that injects the build compiler's GHC version as a CPP define (SETUP_GHC_VERSION) into the executable's cppOptions. The executable prints both the setup-injected version and its own __GLASGOW_HASKELL__, allowing the test to assert the build compiler was actually used.
