Dependents are required to set toolchain directive in go.mod

[bobrik]

A similar issue was reported in #5660, when toolchain was present directly. It was addressed in #5784 and a check was added in #5983.

Unfortunately, since then #5920 changed some go directives from go 1.22 to go 1.22.0, which has a similar effect of forcing consumers to add a toolchain directive, see: grpc-ecosystem/grpc-gateway#5094. See cloudflare/ebpf_exporter#520 for an example of what happens downstream.

From the looks of it open-telemetry/opentelemetry-go and open-telemetry/opentelemetry-go-instrumentation depend on each other and one can no longer simply truncate go directives, as go mod tidy would add toolchain back due to dependencies using go 1.22.0.

I'm not sure how to fix this.

Please try simply removing the toolchain directive after running go mid tidy.

You can also look at:

• cmd/go: toolchain directive in go.mod being updated unnecessarily golang/go#65847

I also want to say that it looks like the Go team is going to recommend using the patch version in the go directive:

The next run of go mod tidy or dependabot will just add it back.

That's disappointing. I'm not sure if there's anything that can be done here other than requiring the oldest toolchain possible.

go 1.22 forces toolchain, while go 1.22.0 doesn't. I'll do that.
