Would it not be useful to indicate that there are failing tests somehow? The result is based on the value that the invoked command returns. That is, for the testing phase, the make test BINDIST=YES command returned ExitSuccess, that is why it is marked green. It'd be a shame to have various test results from multiple machines but not use them. I see what you mean. But I would also feel strange to mark the test results failed if only a few of them fail.

Re: Offering GHC builder build slaves
2014-04-09 0:25 GMT+02:00 Lyndon Nerenberg lyn...@orthanc.ca: Is there any way to verify that builder-client can actually do a successful build, without having access to the build system server? 'builder-client --do-build' wants to connect and authenticate first; it would be helpful if there was a way to bypass that so that I can first verify the local build environment is sane. This is because the builder client gets the commands to be executed from the server. A naive solution would be to put the commands in the script and run it. You can find the current set of installed commands at one of the active builders page, e.g. [1]. Note that you may have to change some of them, such as the flags passed to configure script and name of the make(1) command.

I can offer several build slaves, but I'm not sure what the process is.
As far as I know, the infrastructure has become a volunteer-run
effort, and it looks like I am the volunteer who runs it... :-)
How do I run multiple build slaves?
Ideally, each of the slaves should run in their own isolated (mostly
virtualized) environment.
Do I need a separate username for each?
Yes.
Is there a username convention?
So far I assigned names to the clients by the
${os}-${arch}-${branch} scheme, such as linux-ppc64-head.
The suggestion at https://ghc.haskell.org/trac/ghc/wiki/Builder is
that I post a username and password to ghc@. There are two issues
with this:
Actually, I think this wiki page is not valid any more -- the original
builder infrastructure was abandoned last year. I have started to
replicate the whole thing for my own clients, and it works well (for
me, and nowadays for Karel) since then.
However, my efforts has not been blessed and I am not sure if there
are at least plans to make the builders part of the official
haskell.org infrastructure. Either way it goes, I can update the
corresponding wiki page with my contact information and start
accommodation further clients until the fate of the service is
decided, if there will not be any objections in the next few days.
I am happy to send this information if the admins of the GHC builder
infrastructure are comfortable with the risks.
All right, I can follow up you with the details off-list.

Feel free to modify the wiki so that people find you. Make up some rules (about usernames etc.) as you go, if necessary. That is good to hear.

Re: Offering GHC builder build slaves
Hello all, I was actually going to send an email about this as I'm wrapping up 7.8.1, but since it got started early... Yes, I would really like if someone would be willing to help manage infrastructure for build slaves. If people are willing to support and run with what we've got now, that's great! Simon and I talked about this recently - the decision about what infrastructure to use was somewhat in the air (custom infrastructure has the downside it has less overall support of course), but we figured we'd bring it to the people to discuss, but you beat me to it! Here's a few extra notes: - I can absolutely provide infrastructure, especially for Windows virtual machines, using Rackspace. This is one thing that's missing, and it's how I'm building binaries now. In addition, we can also offer a lot of Linux (and FreeBSD systems) through this. The prices for very low-powered builders are very cheap, and we could easily add several of them for either CI or nightly builds, in 32 and 64bit configurations. This can effectively be free for a lot of supported platforms. - I can also absolutely make any infrastructure 'official' by giving it a domain name, for example, and we can lean on this free infrastructure for what we can, in addition to any machines people are willing to offer. We'll need these extra machines for more platforms! - Whatever we do, I'd really like better visibility. I don't think ghc-builds is enough, personally - historically people seem to ignore it unless someone manages to eye a problem or alert someone else, and I think this was because in the past there was a lot of noise which lead to this sort of perception. But really, it would be great if we could offer a web interface or something. An IRC bot would be useful too - more and more 'regular' users hang out there, and it provides a nice form of passive but responsive feedback. There are certainly fairly pre-canned solutions to this I'm sure. Anyway, whatever we do, I'm happy to support people with the resources, access and visibility they need. Pali, since you seem to leading this - what are your thoughts? I'm more than willing to give you some hardware and put it under haskell.org domain, and just get out of your way if you'd like. :) On Tue, Apr 8, 2014 at 6:59 AM, Alain O'Dea alain.o...@gmail.com wrote: This is great.

I have summarized some of my thoughts in my previous mail to Alain:
I think the best would be if we could cover all the possible and
probable combination of architectures and platforms and avoid the
redundancies.
Earlier, there was the concept of sponsor for the given platform, I
guess it would still make sense to re-introduce it. The sponsor is
somebody who is willing to pay attention to the given platform, run a
builder client for it, therefore maintaining it. For Tier-1
platforms, such support was a requirement back then.
So, we would need to set up at least the following builders: {Linux,
Windows, Mac OS X} {x86, x86_64}, and then I could migrate all the
others I have on my machine to there as well.

Re: Offering GHC builder build slaves
Right, I can provide right now, with minimal fuss::
- 64 bit Linux (32bit as well, if you just use a chroot - not hard.
Rackspace just doesn't provide 32bit VMs by default these days). 24/7
365 availability, roughty.
- 32 bit Windows and 64bit Windows. 24/7 365 availability, roughly.
- I do have a dedicated OS X Lion machine that can be a 64bit Mac
build slave. But no 32bit machine. And occasionally the network
sometimes cuts out, but this is normally fixable and/or transient.
So I think I can already cobble together all the necessary Tier 1
platforms to get us going, I just need to point the machines somewhere
to get them started.
In lieu of anyone else, I can monitor the Windows client. I can
monitor the Linux and OS X builds of course (and do so regularly
anyway), since it seems FreeBSD and Solaris are well cared for
(hooray!) But ideally someone else can do so too, and I'd really like
that! Anyone willing?
I'll look into getting these running with builder clients as soon as
possible and follow up.
