GHC 8.4 Change proposal

[Jens-Ulrik Petersen]

Hi Haskell SIG,

I just have prepared this Change proposal for F30:

https://fedoraproject.org/wiki/Changes/GHC_8.4

Feedback is welcome, as well as offers of assistance if you are able to
help.

Thanks, Jens

It looks like there might be some issues with current builds right
now. Are bumps for everything mostly automated? What needs to be done
on our end?

Yeah, I have rebuilt what is possible from the mass rebuild.

Unfortunately a few libraries got retired recently due to having been
orphaned somehow (fgl, setlocale, hgettext, pcap)

Are bumps for everything mostly automated?

Yeah largely automated by fedora-haskell-tools and cabal-rpm.

This is my usual dilemma: how to share this work...
My only suggest is your are free to bump packages in git master to LTS 12
yourself.
But it might lead to some duplication of efforts; still I don't want to
discourage people from contributing and maintaining their packages so it is
okay. :-)

Finally a progress update...

The Change is running late but I expect to finish pushing and building all
the updated packages in the next few days: building is already underway.

Note that f30 already branched as you probably know, but I am still
building the packages into the f30-ghc sidetag and then releng will tag the
completed builds into both f30 and f31.
Currently I am building from master branch into f30-ghc, but I will be
merging the master branches into f30 rsn...

Please avoid touching master branches and DO NOT commit to f30 branches
until this work is completed, thank you!

If anyone wants me to git push to master sooner to see their changes early
just let me know and I can easily do that.

I have build everything locally (except haskell-platform which may well get
retired), so crossed-fingers everything is looking good so far.
Also I released cabal-rpm-0.13.1 on Hackage which should correspond to the
final f30 packaging.

Let me know if you have questions or concerns,

Jens

Hi,
Everything is built now in f30-ghc: waiting for releng to tag the builds to
f30 and f31.

With the move to ghc-8.4 I am planning to retire the following groups of
packages:

[enumerator is long deprecated and no longer builds out of the box]
ghc-attoparsec-enumerator
ghc-blaze-builder-enumerator
ghc-enumerator
ghc-zlib-enum

[FTBFS]
ghc-bytestring-trie
haskell-platform  [more or less deprecated - no release for 8.4.4]

[weldr packages FTBFS since 8.2]
ghc-bdcs-api
ghc-bdcs
ghc-conduit-combinators
ghc-content-store

[Elliot: this seems no longer needed (has a new dep on cabal-plan) -
ghc-mod is no longer maintained or in Fedora]
ghc-cabal-helper

[got retired recently, but I built bustle without it, so maybe we don't
need it after all]
ghc-hgettext

[the following important core libraries now included in ghc]
ghc-mtl
ghc-parsec
ghc-stm
ghc-text

I retired these from F30 and Rawhide today.

[FTBFS]
> ghc-bytestring-trie

The latest version on Hackage actually builds - the package is not even in
Stackage though.

haskell-platform  [more or less deprecated - no release for 8.4.4]

I am still on the fence on this this one.

Chris, David, Weldr people: can I go ahead and retire these for you now?

Ping :)

These have been retired today too.
