GHC 8.6.1 release status

[Ben Gamari-3]

Hi everyone,

I was getting ready to prepare the final 8.6.1 release tarballs when
Herbert pointed out that the testsuite of his cryptohash-sha256 package
currently segfaults. This appears to be a rather serious, non-deterministic
regression. I've opened #15544 to track this and will delay the final
8.6.1 release until this is resolved.

Cheers,

- Ben

I think the release should include this fix to haddock. Will that happen?

https://github.com/haskell/haddock/pull/905

Will the release contain the fix

    https://github.com/haskell/haddock/pull/893

for the issue

   https://github.com/haskell/haddock/issues/462

too? Without that fix, Haddock is basically unusable for lots of packages under the memory restrictions of Travis CI.

Cheers,

Alex, do you have any objection to merging these?

Hi Ben,

I talked to Alex about these today:

* PR #905 has been merged.

* PR #893 requires the merge of https://phabricator.haskell.org/D5003. Apart from that there were no objections.

Cheers,

Simon

Just another Haddock-related question: Is the fix in https://github.com/haskell/haddock/issues/837 included in 8.6.1, too? Currently I'm a bit confused about exactly which Haddock release/snapshot will be shipped with 8.6.1...

Is the fix in https://github.com/haskell/haddock/issues/837 included in 8.6.1, too?

The fix is both on ghc's ghc-8.6 branch and on haddock's ghc-8.6 branch.

Currently I'm a bit confused about exactly which Haddock release/snapshot will be shipped with 8.6.1...

I'm not sure either. CC'ing Herbert.

As far as I can tell, these changes aren’t yet in GHC 8.6:

* https://github.com/haskell/haddock/pull/905 is on Haddock’s 8.6 branch, but GHC 8.6 hasn’t yet bumped the submodule.

* https://github.com/haskell/haddock/pull/893 is not even yet on Haddock’s 8.6 branch. Note that this one requires matching GHC-side changes to be cherry-picked too.

I think the idea is loosely for GHC 8.6 to ship whatever is in the Haddock `ghc-8.6` branch.

Hello!

I'm having some problem related to plugin recompilation:
https://ghc.haskell.org/trac/ghc/ticket/15564

This prevents inline-java from building with ghc-6.8.1. Perhaps it is
worth checking before the release.

Best,
Facundo

I just replied on the ticket. I think the issue is fixed by D5048.

[lennart spitzner-2]

greetings,

this topic was discussed on mailing list before[1], but I don't think anything came of it. It was also recently discussed on the cabal issue tracker [2] but alas the cabal maintainers have so far not shown interest in resolving the issue.

And while cabal-install caused this problem to surface for many users, the fact that package environment files unnecessarily add state to ghc behaviour holds regardless of cabal behaviour, and must be addressed on ghc's end. I expand on this reasoning in a blog post [3].

Thanks for considering.
