buildRebar3 and buildMix depend less on hex registry #25655

elitak · 2017-05-09T19:28:07Z

Motivation for this change

I was trying to build one of my own projects using packages newer than those in the hex registry and found it was impossible because both Mix and rebar3 were trying to pull in the updated registry after failing to find the requested versions.

Mix has a new environment flag that fixes the behavior, so that change was easy.

Rebar3, on the other hand, still insists on updating the registry even when the built dependencies are present in ./_build/default/lib. The best solution I could come up with short of fixing this in upstream (erlang/rebar3#958) was to change the rebar3 bootstrap to have it generate all of what was symlinked said directory to ./_checkouts instead, sans src subdirs, since rebar3 will try to recompile the source (always, because the derivations lack .rebar3/erlcinfo metadata) into a RO store directory.

My changes to the rebar3 bootstrapping could use review and probably more testing, but as it stands, ./pkgs/development/beam-modules/hex-packages.nix is plenty broken. Does anyone know where is the script that generated this package listing? I need to make a fix there so that packages that depend on broken, elided packages are also elided. It could use a refresh, too.

elitak · 2017-05-09T21:33:35Z

@yurrriq I don't see the script that emits hex-packages.nix, if that's what you meant to link...

ericbmerritt · 2017-05-09T21:36:20Z

The script that updates the registry is update.sh. The code that actually creates hex-packages.nix is here https://github.com/erlang-nix/hex2nix.

elitak · 2017-05-09T21:37:06Z

Ok thanks.

elitak · 2017-05-10T04:34:31Z

Hex2nix isnt building now because I somehow broke rebar3 escriptize with these changes. This is turning into a real mess; I'm getting pretty aggravated by rebar3 not being able to reliably use dependencies I'm laying at its feet. The lack of documentation, code clarity, command-line options, and debug logging in rebar3 is wearing my patience thin.

I might just abandon this and port all my projects to Mix, unless someone who's familiar with the rebar3+nix-bootstrap can offer a better solution than my moving _build/default/lib/* to _checkouts/*, because even if I get that to work, it feels like way too many hacks to accommodate what should be a more robust build tool.

ericbmerritt · 2017-05-10T17:00:08Z

@elitak rebar3 doesn't want to give up dependency management in any way shape or form. I have had conversations with the maintainers and they are not interested in fixing that problem. We had to do quite a number of hacky things to get it working. You are running into all that stuff. Mix was much simpler.

elitak · 2017-05-10T17:05:57Z

Alright, I'm just backing out the rebar3 changes for now, leaving the innocuous buildMix change.

Removing --no-deps-check here broke a lot of builds, since it now runs the deps check. Is running the deps check the intended effect?

yorickvP · 2019-07-02T11:08:24Z

Example of a build that doesn't work anymore:

{
  jason = buildMix rec {
    name = "jason";
    version = "1.1.2";

    src = fetchzip {
      url = "https://github.com/michalmuskala/jason/archive/v${version}.tar.gz";
      sha256 = "0fh87vrfqsyiaazsangsg992i1azad8cmzyzvg7fdm9z6b3v7lm0";
    };
  };
}

lukateras · 2019-07-02T12:14:08Z

Can confirm, --no-deps-check should stay.

We had to do quite a number of hacky things to get it working. You are running into all that stuff. Mix was much simpler.

You can use fake-hex-registry, it was created specifically for that purpose. (I'm going to try to upstream mix-to-nix to Nixpkgs once it doesn't require eval-time builds and fetches).
