Compile error: parse.go:248:77: undefined sqlparser.SCHEMAS about go-mysql-server

[erizocosmico]

I cannot reproduce this error. Can you share the steps you went through to get this error? Are all go-mysql-server dependencies up to date in your vendor folder as well?

[drauschenbach]

@erizocosmico I created an environment to reproduce.

[erizocosmico]

It's because dep is getting the latest vitess version, which has missing things go-mysql-server needs. go-mysql-server uses go modules to manage dependencies, so using go modules should make the problem go away.
If by any reason you can not use go modules and are stuck with dep you should pin the vitess version to v3.0.0-rc.3.0

[drauschenbach]

I see. Thank you.

@erizocosmico I know this issue is closed but maybe you can help me out. I'm using go mod but I can't get this to work.

$ mkdir x && cd x

$ go mod init github.com/bombsimon/x
go: creating new go.mod: module github.com/bombsimon/x

$ go get github.com/src-d/go-mysql-server
go get: github.com/src-d/[email protected]: parsing go.mod:
        module declares its path as: gopkg.in/src-d/go-mysql-server.v0
                but was required as: github.com/src-d/go-mysql-server

# Explicit version
$ go get github.com/src-d/[email protected]
go: finding github.com/src-d v0.5.1
go: finding github.com v0.5.1
go get: github.com/src-d/[email protected]: parsing go.mod:
        module declares its path as: gopkg.in/src-d/go-mysql-server.v0
                but was required as: github.com/src-d/go-mysql-server

# Or older version
go get github.com/src-d/[email protected]
go: finding github.com/src-d v0.4.0
go: finding github.com v0.4.0
go get: github.com/src-d/[email protected]: parsing go.mod:

                but was required as: github.com/src-d/go-mysql-server

Above output is with go1.13, same issue with go1.12 (but another error message).

$ go1.12.10 get github.com/src-d/go-mysql-server
go: github.com/src-d/[email protected]: parsing go.mod: unexpected module path "gopkg.in/src-d/go-mysql-server.v0"
go: error loading module requirements

Seems to be working with other projects with go modules:

$ go get github.com/sirupsen/logrus
go: downloading golang.org/x/sys v0.0.0-20190422165155-953cdadca894
go: extracting golang.org/x/sys v0.0.0-20190422165155-953cdadca894
go: finding golang.org/x/sys v0.0.0-20190422165155-953cdadca894

$ cat go.mod
module github.com/bombsimon/x

go 1.13

require github.com/sirupsen/logrus v1.4.2 // indirect

Any advice?

[erizocosmico]

@bombsimon oh, I see the last release is from before migrating from gopkg.in.

In this case, use:

go get github.com/src-d/go-mysql-server@ b09e8c1c8ab906a3a90cf76115c0a3fc5ee4470a

or any other commit hash to get a specific revision (that one is the master revision right now).

I just asked the maintainer for a new version so this problem goes away without resorting to pinning a specific commit.

@erizocosmico: Thank you so much! I've yet to fully understand some of those special cases regarding go mod but that seems like an easy fix. :) Again, thanks!
