Research direction

Find the golink package definition in Nixpkgs and inspect its source revision and dependency handling. Start by comparing the reported upstream commit with the package’s current version; the build logs identify the vendored Go JSON dependency failures. Update the package to a compatible upstream revision or dependency set, then confirm the package builds under Go 1.27.

Description

0.kind: bug
Nixpkgs version

Unstable (26.11)

Describe the bug
       > Building subPackage .
       > # github.com/go-json-experiment/json
       > vendor/github.com/go-json-experiment/json/alias.go:618:21: undefined: json.SkipFunc
       > vendor/github.com/go-json-experiment/json/alias.go:957:14: undefined: json.DiscardUnknownMembers

I believe the issue is that these were removed in 1.27.

Upstream had to bump dependencies when they changed their Golang version: https://github.com/tailscale/golink/commit/2a5a7c18f5b3ce3e56220d446876e6a386979f40

It may be necessary to roll up the golink version to that revision.

Steps to reproduce

Builds are failing in hydra for all three architectures, for example:

https://hydra.nixos.org/log/51yxcmqs3b5srya09rh9x81gql0nipwq-golink-1.0.0-unstable-2026-07-03.drv
https://hydra.nixos.org/log/c90xcz90dacxpsfc76q6jd7w5vvl77sf-golink-1.0.0-unstable-2026-07-03.drv
https://hydra.nixos.org/log/083yl02kll40cck8z3lisd3ysk8cxg3g-golink-1.0.0-unstable-2026-07-03.drv

Expected behaviour

Things in NixOS should build.
