[WIP] Build plutus-playground-client on Hydra

[michaelpj]

We're not building it or running the tests, which is bad.

I think this adds it to release.nix, but in the process I discovered it doesn't build. Probably sandboxing issues.

I've fixed one (missing python2 dep), but now I'm getting networking errors.

[michaelpj]

If you work out what it is, feel free to push to this branch. Hydra's going to take a while since this is the first time it's built any of the dependencies.

[michaelpj]

Okay, it indeed fails in a similar way.

It’s because we’re using a special nixpkgs, but that’s not defined in the jobset, so it won’t be prefetched. So it can’t be reached from inside the sandbox.

We have to see if we can build without that extra nixpkgs fork, and if not, get it fed through from the jobset.

[shmish111]

it doesn't build without that fork

[michaelpj]

That's not the issue, the extra nixpkgs is just fine. It gets way past that.

[michaelpj]

fetchtarball is fine in sandboxing otherwise literally nothing would work ;)

[michaelpj]

It's some node-gyp thing.

[shmish111]

yeah it's trying to build nodejs, something deep inside, not one of our derivations

[michaelpj]

No, it's during the build of plutus-playground-client. I don't know why that's calling node-gyp to do something but it is.

[shmish111]

gyp http GET https://nodejs.org/download/release/v6.12.2/node-v6.12.2-headers.tar.gz is what fails

[michaelpj]

Maybe your yarn.nix is out of date so it's trying to build some of the missing packages?

[shmish111]

no, seems to be up to date, it would probably fail to build in non-sanboxed if that were the case

[michaelpj]

It's happening during yarn install, for some reason node-sass is doing stuff. It is included in yarn.nix, so I'd have thought it shouldn't be doing stuff...

[michaelpj]

Maybe you need to do something like this? https://stackoverflow.com/questions/45424094/how-to-get-yarn-install-offline-with-node-sass-working

[michaelpj]

Can't see how to get the binary binding that it wants from anywhere. Going to leave this in your court...

[michaelpj]

fetchurl-ing the binaries from their releases page seems to work.
