Unexpected downloads with `cabal repl` in 3.9 prerelease

[geekosaur]

Describe the bug
I just rebuilt my xmonad config using the new cabal prerelease. The standard build went as expected, but the secondary build with cabal repl (so I have a "hot" config I can use for quick testing) unexpectedly downloaded but did not build a number of packages.

To Reproduce
Steps to reproduce the behavior:

This assumes you have cloned https://github.com/xmonad.hs/tree/skkukuk; and it may require that you have done an earlier build with cabal 3.8.1.0 and the Hackage index per cabal v2-update 'hackage.haskell.org,2023-01-20T16:06:23Z'.

$ sh ./update.sh
Go update github xmonad and xmonad-contrib; I'll wait…

Please use version-prefixed commands (e.g. v2-build or v1-build) to avoid ambiguity.

Expected behavior
The build for ghci should match the one for the executable.

System information

• Ubuntu 20.04.1
• cabal 3.9 (prerelease), ghc 9.2.5

Additional context
The current version of the update and build scripts includes annotations of the commands being run, unlike the log which I took from my terminal. You can look in update.sh and build for details; note that build is invoked with the name of the target xmonad config executable.

I worried it might be caused by this, but on closer inspection I doubt it #8500

[Mikolaj]

Could you kindly check if the bug if perhaps gone in this version with some fixes: https://gitlab.haskell.org/haskell/cabal/-/pipelines/63307

The commandline to get the Linux version via ghcup is
ghcup --no-cache install cabal -u 'https://gitlab.haskell.org/haskell/cabal/-/jobs/1376184/artifacts/raw/out/cabal-install-3.9-x86_64-linux-alpine.tar.xz' internal-second-prerelease-of-3.10

[geekosaur]

I'm testing it now, but I haven't seen a repeat since then and suspect I would have to rewind my packages store (not cabal store) to an older version somehow to trigger it again.

[Mikolaj]

Another one to try. This one is not a hip shot, but should really fix it (artifacts at the bottom of the right pane of this page): https://github.com/haskell/cabal/actions/runs/4179798663
