RE: [commit: vector] master: Implement poly-kinded Typeable (8b27167)

Hang on... vector has an upstream repo; see http://hackage.haskell.org/trac/ghc/wiki/Repositories and in particular the "Upstream repo?" bullet. So we may need to do more than push to the mirror?

GHC 7.8 release?
by Simon Peyton-Jones 12 Feb '13

12 Feb '13

Dear GHC users, Carter: Will this RTS update make it into ghc 7.8 update thats coming up in the next monthish? Andreas: We are almost there - we are now trying to sort out a problem on mac os x. It would be helpful to know if there is a cutoff date for getting things into 7.8. Simon, Ian, and I have just been discussing 7.8, and would be interested in what you guys think. At ICFP we speculated that we'd make a release of GHC soon after Christmas to embody tons of stuff that has been included since 7.6, specifically: · major improvements in DPH (vectorisation avoidance, new vectoriser) · type holes · rebindable list syntax · major changes to the type inference engine · type level natural numbers · overlapping type families · the new code generator · support for vector (SSE/AVX) instructions Whenever it comes it would definitely be great to include Andreas & friends' work: · Scheduler changes to the RTS to improve latency The original major reason for proposing a post-Xmas release was to get DPH in a working state out into the wild. However, making a proper release imposes costs on everyone else. Library authors have to scurry around to make their libraries work, etc. Some of the new stuff hasn't been in HEAD for that long, and hence has not been very thoroughly tested. (But of course making a release unleashes a huge wave of testing that doesn't happen otherwise.) So another alternative is to leave it all as HEAD, and wait another few months before making a release. You can still use all the new stuff by compiling HEAD, or grabbing a snapshot distribution. And it makes it hard for the Haskell platform if GHC moves too fast. Many people are still on 7.4. There seem to be pros and cons each way. I don't have a strong opinion. If you have a view, let us know. Simon

RE: GHC 7.8 release?
by Simon Peyton-Jones 10 Feb '13

10 Feb '13

, even a point release (7.6.2 vs. 7.6.1) of ghc tends to be moderately violent with respect to the Platform. Ideally, such a point release should not be difficult to slot in because it should be compatible modulo bug fixes, but with ghc's release strategy nobody has any confidence in it being that simple. Well our clear intention for point releases (7.6.1 to 7.6.1) is that they should break nothing. I am concerned that in your experience point releases are “moderately violent”. We go to some pains to make sure that we don’t break anything. If we don’t succeed on this point-release policy, please do tell us when the release candidate comes out. If we don’t know we are causing pain, we can’t stop inflicting it :-) (Major releases are another matter. There, things are likely to break.)

Compiling DynFlags is jolly slow

Even the non-generated code in DynFlags is quite large, and ungainly to edit. What would you think about splitting it up, perhaps moving DumpFlag, GeneralFlag and WarningFlag into separate modules? Ideally each module would also export a [Flag (CmdLineP DynFlags)], which would then be ++ed together in DynFlags, but I'm not sure if that's possible without making the modules mutually recursive. On the other hand, perhaps there's a way to split it up which would remove the need for (some of) the existing import loops; I'm not sure how feasible that is OTTOMH. Thanks Ian

No instance for (Fractional Int32)
by Gabor Greif 09 Feb '13

09 Feb '13

Hi all, This is what I get while building a cross-ghc: libraries/base/Foreign/C/Types.hs:162:72: No instance for (Fractional Int32) arising from the 'deriving' clause of a data type declaration Possible fix: use a standalone 'deriving instance' declaration, so you can specify the instance context yourself When deriving the instance for (Fractional CFloat) Has anybody seen this with HEAD? Cheers, Gabor
