dgraph-alpha.service is broken

[KaiLemke]

Describe the bug

Setting up dgraph using the options services.dgraph.* results in a functioning dgraph-zero.service and a broken dgraph-alpha.service.

It seems to me dgraph is complaining about having the acl flag which is not available / appliacble for the OSS version. But the flag is not set nor are there setting or variables for ACLs.

Steps To Reproduce

Steps to reproduce the behavior:

1. Run sudo nixos-container create dgraph --flake 'gitlab:dgrow/dgraph.nix/5821e5bd78a39b09a5840e2877e6dbb0b5d6f398#container'
2. Run sudo nixos-container start dgraph
3. Run sudo nixos-container root-login dgraph
4. Inspect dgraph-zero.service and dgraph-alpha.service

I also tried without services.settings and services.dgraph.*.host and explicitly setting --acl "" without effect.

Expected behavior

dgraph-alpha.service starts - at least if the only setting is services.dgraph.enable.

Yes, I know it's broken, but the system is configured via nix flakes only and I don't have problems with containers usually.

[KaiLemke]

For comparison: If I start a docker container with https://hub.docker.com/layers/dgraph/standalone/v22.0.1/images/sha256-f649c7e17a0c9c7fd5fce4a0b398c3d16a9ed67bbbb59d3096985f204e091435?context=explore, I get no logs about this acl flag and dgraph version looks like this:

I get the same failure just running dgraph zero & dgraph alpha with dgraph from nix shell 'nixpkgs/nixos-22.11#dgraph'.

The version from nixos-22.05 worked fine, though the version output differed also:

What's different in 22.11 is, that the go version is different from the official docker image, in 22.05 not.

[happysalada]

Hey thanks for reporting ! I havent run dgraph in a whike unfortunately. I see two things that could potentially help. Update the version of dgraph to the latest. Check the output of the command journalctl -u dgraph-alpha There might be additional information in there.

Hi, I tried to upgrade to v22.0.2, but the build failed due to a dependency:

vendor/golang.org/x/sys/unix/syscall_unix.go:118:7: unsafe.Slice requires go1.17 or later (-lang was set to go1.16; check go.mod)

I'm a bit confused, because go.mod lists golang.org/x/sys v0.0.0-20221010170243-090e33056c14, but https://deps.dev/go/golang.org%2Fx%2Fsys/v0.4.0/versions does not list that version.

Also buildGoModule should use go1.19 - where does the go1.16 come from? I didn't work with buildGoModule before. So sorry, if I'm asking obvious things. ;)

Have you any ideas what's going on here?

[KaiLemke]

For completeness I already started a draft merge request: #212130

[happysalada]

Just as foreign to me. I dont know where this could come from.

I tried searching in yhe dgraph repo to see if it wasnt something set there. Couldnt find anything

I also tried changing the go version in nix to 18 and 17, but same failure.

I wish i knew more about go, but unfortunately, im a rust dev.
