Cannot upload `cabal-version: 3.8` package to Hackage

[RyanGlScott]

When I attempt to upload singletons-base (which needs cabal-version: 3.8) to Hackage, it fails with:

$ cabal upload --publish dist-newstyle/sdist/singletons-base-code-generator-0.1.tar.gz 
<snip>
Uploading dist-newstyle/sdist/singletons-base-code-generator-0.1.tar.gz...
Error uploading dist-newstyle/sdist/singletons-base-code-generator-0.1.tar.gz:
http code 400
Error: Invalid package

'cabal-version' must be at most 3.6

Is there something that needs to change on Hackage's end to support this? I require cabal-version: 3.8 due to the package's use of a cabal code generator.

I am using the latest stable release of cabal (cabal-install version 3.12.1.0) as of the time of writing.

Didn't realize we still had that upper-cabal-spec bound. I've disabled it in the code, but will need to schedule a hackage redeploy -- perhaps this weekend.

[RyanGlScott]

Thanks! Let me know if there is anything I can do to help.

[RyanGlScott]

Any update on this, @gbaz?

[RyanGlScott]

In the meantime, I am going to revert the use of a code generator, as it is effectively incompatible with Hackage.

[gbaz]

Sorry about the delay. Will try to get to this very soon.

[gbaz]

And the update is now complete, sorry for the delays.

[RyanGlScott]

I am still getting the same error when attempting to upload the package just now. Am I doing something wrong?

@gbaz I think 8882476 was not backported to central-server branch, it still points to

hackage-server/src/Distribution/Server/Packages/Unpack.hs

Lines 222 to 224 in ec45aab

	-- To keep people from uploading packages most users cannot use.
	unless (specVer <= CabalSpecV3_6) $
	throwError "'cabal-version' must be at most 3.6"

I believe the whole batch hasn't been merged yet but Gershom thought it was? #1352

[gbaz]

indeed, doing a new redeploy now. 🤦

[gbaz]

and done, hope i got it right this time.
