Remove replace directives from go.mod

[mmannerm]

What is the underlying problem you're trying to solve?

go run github.com/open-policy-agent/[email protected] or go install github.com/open-policy-agent/[email protected] will not work and results in to an error

go: downloading github.com/open-policy-agent-opa v0.68.0
go: github.com/open-policy-agent/[email protected] (in github.com/open-policy-agent/[email protected]):
    The go.mod file for the module providing named packages contains one or
    more replace directives. It must not contain directives that would cause
    it to be interpreted differently than if it were the main module.

The replace statement in question is go.mod#L120.

replace github.com/golang/glog => ./build/replacements/github.com/golang/glog

Describe the ideal solution

The ideal solution would be that you can go run the opa policy agent directly via go run or you can install it directly with go install instead of relying on package manager.

Describe a "Good Enough" solution

Creating RPM packages and other packages for easier installation of opa executable is more work than fixing the replace statement.

Additional Context

The golang team is not willing to support replace statements with go install or go run: golang/go#44840

Hi there! And thanks for filing this issue. And I agree, that would be nice. The trade-off we're looking at seems to be between supporting go install vs. providing a poor experience for Windows users on the official binaries. And supporting our distributed executables are likely always going to be prioritized higher than go install support. But obviously, if we can do both, we should!

Indeed. In that case it was a no-brainer to just get rid of the replace, while it solves (or at least solved!) an actual issue here. But looking at the git history, that replace is from 2022, and I don't think anyone looked at it since then. So it could very well be that the issue has been fixed upstream. I don't have much time to look into it this week, and no windows machine to test with 😅 But if someone has the bandwidth to investigate, that would be much appreciated!

I'll have a quick look.
