[ENHANCEMENT] Publish binaries to github releases

[ThetaSinner]

I've made a start on this. We can't export the binaries that are built with Nix directly because they depend on glibc 2.38 where the LTS Ubuntu for example currently uses 2.35. So most people wouldn't be able to run the binaries.

I'm looking instead at producing musl builds. I am able to do this with Cargo now but haven't figured out how to do it with Nix. It also needs a new version of tx5 in Holochain because I had to make some changes to support musl there too.

it maybe also be looking at alternatives that might be easier to maintain long-term, e.g. [bundling the shared libraries alongside the binary into a self-contained bundle with nix-bundle, or bundling into AppImages.

haven't figured out how to do it with Nix.

since we're already using crane this could be helpful: https://crane.dev/examples/cross-musl.html

Another point that came up in this discussion was which features the release binaries should have turned on. We should look at turning on sqlite_encrypted and probably also do a check over other features to make sure a sensible set is turned on in the binaries we publish.

The quick and dirty way to do this would be to do a nix develop --override-input holochain . --override-input versions ./versions/weekly .#holonix -c <my script> and provide a script to attach the binaries to the release. I suspect a better way to deal with this would be to add a new derivation which outputs the binaries we want to release and use nix build to build them into a local directory to be uploaded. There's less risk of the PATH causing unexpected issues that way.

Oh I see, features is dealt with on #2957 👍🏻

@steveej FYI

[mattyg]

Yeah sorry I think I won't have time to attempt this

[ThetaSinner]

No worries, I think there are a few non-obvious pieces of complexity to this one. I would love a week to just work on CI improvements like changelogs, pulling information from other repos like lair on release, dumping out a the current set of libraries so people can see what to use together, and this. I might be able to find some time before the end of the year but it might be a new year thing this now unfortunately.
