Hi Shayne,

If you think you may be able to help with MacOS resources let's chat.
This is certainly an area where we could use help. Currently we have two
boxes which are generously provided to us by Davean Scies. These tend to
struggle with the load and consequently jobs sometimes timeout before
they are able to get a builder. It would be great to be able to do
better here.

Cheers,

- Ben

Exactly. One problem at a time. Preventing changes that break the hadrian
build from landing is what I advocate we concern ourselves with today.

Re: Fwd: [hadrian/windows] build broken

2019-05-30 Thread Alp Mestanogullari 
I haven't (yet) worked on making an OS X job for Hadrian. I brought back 
the Windows/Hadrian CI job with that fix, but then tried running the 
testsuite, which didn't go well, see:


https://gitlab.haskell.org/ghc/ghc/merge_requests/1035

https://gitlab.haskell.org/alp/ghc/-/jobs/87467

This seems to have brought back a problem that Ben and I started looking 
into and which led us to disabling that job in the first place... 
However, running the testsuite is one thing, but just making sure we can 
build GHC is another. I guess I can put together a patch to get us an OS 
X job that just builds GHC pretty quickly, and then later get both the 
Windows and OS X jobs to go as far as running the testsuite. That'd at 
least give us confidence that people can build GHC with Hadrian just 
fine on OS X.


Regarding the resources, that certainly sounds like something that would 
help if we are to double the number of OS X builds, indeed. I'm sure Ben 
(cc'd), who handles those matters, would be happy to talk about this 
with you!


In the meantime, I will prepare a patch to add an OSX/Hadrian job.

If the error persists, you'll probably want to do a clean build,
by removing at the very least _build/stage1, even though I'd say
it can't hurt to remove _build altogether. Along with that patch,
I also brought back the Windows CI job and the error did not show
up there, so I'm pretty confident you will not run into it again
with a fresh, clean build.

It's cooking now. Looking promising :) I build fresh every time. Good 
news on the Windows CI!! On that note, how are we doing on the MacOS 
front ? (Let me know if we need resources to make that happen - might 
be able to help if so!).


Do feel free to contact me or open a ticket if somehow the error
still shows up, even against a clean tree.

You bet. Thanks for your hard work!

Heh, it landed less than an hour ago.

If the error persists, you'll probably want to do a clean build, by 
removing at the very least _build/stage1, even though I'd say it can't 
hurt to remove _build altogether. Along with that patch, I also brought 
back the Windows CI job and the error did not show up there, so I'm 
pretty confident you will not run into it again with a fresh, clean build.

Re: Fwd: [hadrian/windows] build broken

2019-05-23 Thread Alp Mestanogullari 
Yes. We actually had one until a few weeks ago but it became really 
unstable because of some cache messing about with cabal-install's 
ability to build Hadrian, see 
https://gitlab.haskell.org/ghc/ghc/issues/16574.


I need to figure this out soon indeed, I'll do my best to get us a 
working Windows/Hadrian job ASAP.

Ooops I've let this thread pass by me, but this is most likely due to 
my latest refactoring of libffi rules in Hadrian. No need to create a 
new issue, I'll just reopen #16304, and have a look at this now.


On that note, Alp, are we planning on adding a hadrian/windows CI job 
soon?
