Adding Ben, Roman, Gabi SImon | -----Original Message----- | From: ghc-devs [mailto:ghc-devs-bounces@haskell.org] On Behalf Of | Austin Seipp | Sent: 04 August 2014 12:48 | To: ghc-devs@haskell.org | Cc: Manuel Chakravarty; Geoffrey Mainland | Subject: I'm going to disable DPH until someone starts maintaining it | | Everyone, | | I'm still working on the AMP, and of course, things aren't going as | planned. Why is that? | | I'm attempting to update `vector` to the latest version from GitHub, as | it has some fixes we need for AMP. Mostly, it has some instances we | need. | | Unfortunately, this is basically impossible because dph is locked into | a vector fork of ours that we have been maintaining for *months*, and | doesn't work with the latest vector upstream (0.11) due to changes in | the stream representation. This means I can either: | | 1) Fix everything in DPH to work with vector 0.11, which is probably | going to take a lot of work. | 2) Merely fix our fork of vector and let things continue working. | This is much easier than #1. | | Now, you might say that #2 is clearly a preferable solution, and it's | very easy - so just do that, Austin! | | But I don't want to do it. You could say this is the straw that has | broken the camel's back. | | Why? Because I'm afraid I just don't have any more patience for DPH, | I'm tired of fixing it, and it takes up a lot of extra time to build, | and time to maintain. | | In fact I'm the only person who's committed to it in *months*, and that | has only been to fix breakage. The hackage packages are out of date and | sync with what's in the repository (I can't upload them, nor can anyone | else besides Ben I believe). | | So - why are we still building it, exactly? | | We had a conversation about this months ago. The concern was that | things would break and we don't want it to fall out of sync. We're at | that point right now - things are breaking, it's out of sync, and it's | a pain to keep fixing it, and the actual *benefits* we get from doing | so are completely unclear to me. It basically just seems like extra | work for nothing, honestly. | | Unless someone speaks[1] up *very* soon, I'm going to disable DPH | during ./validate and the regular build. It will be possible to build | it with a '--dph' flag (the dual of the current '--no-dph' flag), | although it will be broken very soon with these incoming changes. | | Providing someone starts fixing it, I'm completely, 100% open to re- | enabling it in ./validate by default. But I'm personally tired of | fixing it. | | I'm CC'ing Manuel, Geoff & Ben for their inputs. | | [1] And by 'speak up', I mean I'd like to see someone actively step | forward address my concerns above in a decisive manner. With patches. | | -- | Regards, | | Austin Seipp, Haskell Consultant | Well-Typed LLP, http://www.well-typed.com/ | _______________________________________________ | ghc-devs mailing list | ghc-devs@haskell.org | http://www.haskell.org/mailman/listinfo/ghc-devs
