I'd just like to query the status of the nightly builds. Is anything happening in that area? [1] is right on the front page of the GHC Trac even though no builds were ran for ~5 months. Perhaps it should be moved out of the way if there's no plan to resume these in the near future.
just to clarify: For what purpose do you want the nightlies? To check whether GHC validates cleanly, to compare performance numbers, or to get hold of up-to-date binary distributions?
Personally it's to see what validates that day and while we're at it, I don't see the reason to not use this to get the nightly binaries as well. I agree with pretty much everything that Páli said in his reply. If we can get the validate results from other people's machines, at the very least we have a sanity check: does it only fail for me or for everyone else too? I think that if we have a list of platforms with angry red everywhere, accessible to everyone, people are more likely to react to build failures and we're less likely to have e-mails on ghc-devs from people going ‘is it just me or is it failing for everyone?’.
For the first, I’d really really like to see something that runs before a change enters master, so that non-validating mistakes like http://git.haskell.org/ghc.git/commitdiff/b26e2f92c5c6f77fe361293a128da637e7... (without the corresponding change in http://git.haskell.org/ghc.git/commitdiff/59f491a933ec7380698b776e14c3753c2a...) do not reach master in the first place.
I’m happy to help setting up such an infrastructure, including designing the precise workflow.
I think doing a per-commit validate before something enters master would be difficult simply because one would have to wait a long time before their commit is allowed in. Even on the fast boxes, the quick validate from clean checkout seems to take about an hour at best.
For the second and third, a build farm like the builders would of course be great. I actually once got a Igloo snowboall from Linaro for that purpose, but never finished setting it up properly. So once the builders are going to be revived, I’d like to finally do that.
Greetings, Joachim
