guix: Pin Guix using `guix time-machine` #17933

dongcarl · 2020-01-15T17:20:31Z

An alternative to #16519, pinning our version of Guix and eliminating a guix pull and changing the default Guix profile of builders.

I think this method might be superior, as it:

Eliminates the possibility of future changes to the guix environment command line interface breaking our builds
Eliminates the need to set up a separate channel repo

It is a more general pinning solution than #16519.

The reason why I didn't originally propose this is because guix time-machine is a recent addition to Guix, only available since f675f8dec73d02e319e607559ed2316c299ae8c7

Eliminates the need to set up a separate channel repo

Wasn't the conclusion that the channel could be in the same repo? See #16519 (comment)

Though, I guess the time machine still makes sense when we can switch it to vanilla upstream and not use dongcarl/guix?

Ah sorry, what I meant to say is that using time-machine eliminates the need for any channel/inferior whatsoever! You define some extra packages in the manifest, and just point directly to the version of Guix you want. This is why this diff is so small.

Previously in #16519, we had to point to the channel (which contained some extra packages), which in turn pointed to the version of Guix we wanted.

Side benefit: if we used channels in bitcoin/bitcoin or in bitcoin-core/packaging, we would need a .guix-channel file at the root of the tree. This method doesn't.

Approach ACK 4763171ff7ad03e654ccd9f78b5ac5ab17aecd25

Concept ACK

Side benefit: if we used channels in bitcoin/bitcoin or in bitcoin-core/packaging, we would need a .guix-channel file at the root of the tree. This method doesn't.

Big ++ if this means the project doesn't have to maintain more build / packaging infrastructure.

I've completed a Guix build using this PR (4763171) and this Docker container:

Why is this a draft?

fanquake

The reason why I didn't originally propose this is because guix time-machine is a recent addition to Guix, only available since f675f8dec73d02e319e607559ed2316c299ae8c7

Given that Guix is a new addition to the project, and there's only a few people doing builds, I've got no issue with us requiring Guix master for now.

I've completed time-machine builds for Linux and Windows. macOS builds are also working as far as I know; I haven't done a build yet, because I haven't got an SDK with the headers packaged.

I've taken a quick look at the 2019-10-bitcoin-staging-GREAT-CORE-UPDATES-MERGE branch as well. I can see the changes you've made match some upstream discussion on the Guix mailing list here.

It also seems that your commit with David Truby's fix for libstdc++ has now made it into Guix master 496bbeee7a0afbf1c7cbcc0de8c33c2111cb661f. So I guess will be dropped when you pull upstream.

@dongcarl I'd be pretty happy for us to merge this change. Will ACK once you mark as ready for review.
