go-winio module problem

[Green7]

I can't install go-winio module.
go version 1.12..7 on Windows, without go-winio on disc.
I create new project and execute:
go mod init test
go get github.com/microsoft/go-winio

go: github.com/microsoft/go-winio@v0.4.13: parsing go.mod: unexpected module path "github.com/Microsoft/go-winio"
go: error loading module requirements

You can add this to your go.mod until its merged:

replace github.com/microsoft/go-winio => github.com/balboah/go-winio v0.4.14

The current name is github.com/Microsoft/go-winio, per https://github.com/microsoft/go-winio/blob/master/go.mod#L1, so this just looks like user error?

Looking across the Go projects in github.com/microsoft, it's a mixed bag of microsoft (20) vs Microsoft (14), and it seems that microsoft is canonical.

Go 1.13.8 gives a more-useful error in this case:

paulh@KEITARO:~/tt$ go version
go version go1.13.8 linux/amd64
paulh@KEITARO:~/tt$ go mod init test

(Users of x/sys/windows don't work on non-Windows, but that's a different issue)

Unfortunately the organization was renamed a couple of years ago from Microsoft -> microsoft, which caused many issues for Go projects. We decided we wouldn't change the repo's casing, as that would break existing users, but there are certainly still issues when other projects use the lower-case org name.

Testing with go 1.15, even on Windows (case-insensitive filenames), go won't use a miscased module:

> go mod init test
go: creating new go.mod: module test
> go get github.com/microsoft/go-winio
go: downloading github.com/microsoft/go-winio v0.4.16
go: github.com/microsoft/go-winio upgrade => v0.4.16
go get: github.com/microsoft/go-winio@v0.4.16: parsing go.mod:
        module declares its path as: github.com/Microsoft/go-winio
                but was required as: github.com/microsoft/go-winio
> go version
go version go1.15.5 windows/amd64

So assuming the problem persists only with pre-modules Go packages, the ecosystem should clean itself over time, and certainly won't get any worse, unless people are deliberately making it worse bypassing the check with rules like

replace github.com/microsoft/go-winio => github.com/Microsoft/go-winio v0.4.16

except working.

I'm not seeing any issues with different repos from the same owner with different casing either.

> go get github.com/Microsoft/go-winio
go: github.com/Microsoft/go-winio upgrade => v0.4.16
> go get github.com/microsoft/moc
go: downloading github.com/microsoft/moc v0.10.5
go: github.com/microsoft/moc upgrade => v0.10.5

@TBBle Thanks for checking on this! Good to hear that it sounds like modules makes it easier to detect when the wrong casing is being used.

Since it sounds like this issue is resolved by using the correct casing in the go get invocation, I'm going to close this out.
