Description

The SDK HELO version seems incorrect.

Steps to reproduce:

Spin up a one node cluster with the default bucket

Use the following Go code

package main

import (

    "fmt"

    "gopkg.in/couchbase/gocb.v1"

type User struct {

    Id string `json:"uid"`

    Email string `json:"email"`

    Interests []string `json:"interests"`

func main() {

        gocb.SetLogger(gocb.DefaultStdioLogger())

        cluster, _ := gocb.Connect("couchbase://localhost")

        bucket, _ := cluster.OpenBucket("default", "")

        bucket.Upsert("u:kingarthur",

                User{

                        Id: "kingarthur",

                        Email: "kingarthur@couchbase.com",

                        Interests: []string{"Holy Grail", "African Swallows"},

                }, 0)

        var inUser User

        bucket.Get("u:kingarthur", &inUser)

        fmt.Printf("User: %v\n", inUser)

build and execute

Tail the memcached.log:

2017-11-10T18:26:58.200201Z NOTICE 43: HELO [gocb/v7.0.5] [ 10.111.163.1:64882 - 10.111.163.101:11207 ]

As you can see the HELO version of the SDK is gocb/v7.0.5 I was expecting 1.30, as I believe that is the SDK version being used.

Hey Patrick Varley,

The Go SDK is actually made up of two somewhat independently developed projects, gocbcore which implements all of the connection, protocol and configuration management, as well as gocb on top which provides a more sane API for developers to use. The version which is reported to the server is the gocbcore version (as this is the one which would actually impact the behaviour of the client). Note that the reason we cannot send the gocb version is that there is no way to map a specific gocb version to a specific gocbcore version due to how Go's package management works. For instance, if you checked out gocb last month, you would get gocb.v1.3.0 and gocbcore v7.0.4. However, doing the exact same installation today would yield instead gocb.v1.3.0 and gocbcore v7.0.5. Note that the gocb version hasn't been updated, but gocbcore underneath has been.

Cheers, Brett

Surely the correct thing to do would be to report both modules?

Hey Patrick,

What would be the benefit of this? The gocb library doesn't have any tangible impact on the clients behavior, its simply a forwarding layer.

So we can identify problematic SDK versions and proactively inform customer.

From a end user DBA point of view they can see what clients are connected and what versions they are on.

This is what the other SDKs too:

Java SDK sets both the core and top level client versions in the HELO
Python SDK sets the libcouchbase and python SDK versions in the HELO
