Current state of ghc boot lib versions vs. hackage

[Jan Stolarek]

I'm still not sure how to handle libraries that I modified with my primops change (#6135): primitive and array. There is some discussion on the core libraries commitee list and it seems that I'll have to further modify primops, and thus primitive and array, before 7.8 is released. Should I submit my patches to maintainers of these two libraries? Also, in order to make updated versions of the libraries compatible with older versions of GHC I would need to add some #ifdef pragmas. The question is whether we and package maintainers want that compatibility or should we expect that newly released versions of primitive and array will require at least 7.8 to run?

Temat: Re: Current state of ghc boot lib versions vs. hackage

Hello Herbert,

I think that current GHC HEAD's primitive and vector are undesirable version.

Because:

   1. GHC HEAD's primitive and vector are older than latest released version. (You already pointed out that.）
   2. But ... GHC HEAD's primitive and vector have some changes from older released version (to build with GHC HEAD).
   3. primitive HEAD and vector HEAD has some changes from latest release. These are not same as above GHC HEAD's changes.
   4. We can't merge simd branch's primitive and vector changes before merging primive HEAD and vector HEAD' changes. (Becuase simd branch's primitive and vector depend on primitive HEAD and vector HEAD's changes.)

By above reasons, I think that GHC HEAD should merge primitive HEAD and vector HEAD's changes.


Best Regards,
