Haddock --quickjump is broken with GHC 9.2.2

[guibou]

Describe the bug

I'm using --quickjump in my haddock_flags and hit haskell/cabal#8104 with GHC 9.2.2 and haskell_doc does not build anymore.

To Reproduce

• Use GHC 9.2.2
• Add --quickjump in your haddock_flags
• bazel build //path/to/some/haskell_doc:rule

Expected behavior

It should build the haddock documentation, but instead it fails with:

haddock: internal error: external/rules_haskell_ghc_nixpkgs_haskell_toolchain/haddock/interfaces/doc-index.json: openBinaryFile: does not exist (No such file or directory)

The workaround is to remove --quickjump from the list of haddock_flags.

Note that the linked issue above suggest to replace --haddock-quickjump by --hadock-options=--quickjump, but that's what is done in cabal, AFAIK by passing --quickjump to haddock_flags, that's exactly the workaround they suggestion, so it appears that the setup I was using is the same as the workaround they suggest, but it does not fix the problem.

Hence I suppose that something else changed in GHC 9.2.2 in the way haddock works.

Environment

• OS name + version: nixos
• Bazel version: 4.2.2 from nixos
• Version of the rules: a dozens of patchs on top of ea0e70a

Additional context

I'm mostly opening this for reference, I'm satisfied with removing quickjump for now, but it may help any other rules haskell user.

I can reproduce this with GHC 9.2.8 and according to this comment here it will not work for GHC 9.2 since the relevant fix has never been backported.

Using GHC 9.4.6 works again. I'll leave this open for now, but it's not a bug on our end.
