ghc-7.4.2 and other updates/news
by Jens-Ulrik Petersen
Hi,
I want to update the SIG on various news:
* ghc-7.4.2 and haskell-platform-2012.4
I have started work locally testing updating rawhide to ghc-7.4.2
and haskell-platform-2012.4 RC2. If people want I can upload
my local ghc-7.4.2 and haskell-platform builds for testing.
Overall the results so far are fairly good.
Only a few remaining packages have problems:
- Agda (constructor issue)
- happstack-server (blaze-html or new deps)
- hledger-lib-0.19 needs shakespeare-text (review pending)
- xss-sanitize (css-text not imported yet!)
but they should be fixable by F19 time.
I plan to build ghc-7.4.2 for Rawhide within the next week.
* Updating packages to latest versions
We have a lot of packages that need a version refresh.
Now is a great time to bump your packages in git master.
Building for rawhide is also ok but not really necessary right now
since everything will need rebuilding shortly soon anyway.
I really need your help with this, but if you don't have time to do it
I will start touching packages generally in the coming week or so.
* cabal-rpm update
I have been using cabal-rpm to refresh a few packages by hand
and I am going to release 0.6.5 soon with some smaller tweaks
and improvements: the biggest visible change being no longer using
version-ranged BRs since I think this has too much maintenance
overhead at least until cabal-rpm can do updating of packages.
* Haskell Platform and ghc versions
I am wondering how closely we should follow Haskell Platform going
forward since the releases are not well synced with Fedora's schedule
and upstream so far refused to shift its schedule...
As such I quite like following HP - it is gives us a certain stability
and certainty of base versions, but also understand that some people
want to have the latest versions available and live on the bleeding edge.
Personally I am leaning towards doing more backporting - I am thinking
to backport ghc-7.4.2 and haskell-platform-2012.4 to F18 for example
(after it has gone to rawhide). If there is demand we could also
backport ghc-7.4.1 to F17 perhaps or I could make a yum repo for it
from the F18 packages. Ubuntu-12.10 just recently shipped with ghc-7.4.2.
What do people think? How important is it to have the official
haskell-platform in Fedora?
Another side issue is that I somewhat cavalierly made haskell-platform
into a monolithic package in F18, thinking this would decrease its update/build time.
This unfortunately means if we weren't going to follow HP closely we
would probably need to re-review all the HP packages again... :-/
