matthewrankin opened a new issue #89: Remove redundant Unmarshal in 
`gobuild.py.launcher.go`
URL: https://github.com/apache/incubator-openwhisk-runtime-go/issues/89
 
 
   Below are lines 71–91 of [`common/gobuild.py.launcher.go`][1]. Line 83 
appears to be redundant and unnecessary, as it is the same as line 73, which 
has already unmarshalled the data.

   ```go
                // parse one line
                var input map[string]interface{}
                err = json.Unmarshal(inbuf, &input)  // Line 73
                if err != nil {
                        log.Println(err.Error())
                        fmt.Fprintf(out, "{ error: %q}\n", err.Error())
                        continue
                }
                if debug {
                        log.Printf("%v\n", input)
                }
                // set environment variables
                err = json.Unmarshal(inbuf, &input)  // Line 83: Appears to be 
redundant.
                for k, v := range input {
                        if k == "value" {
                                continue
                        }
                        if s, ok := v.(string); ok {
                                os.Setenv("__OW_"+strings.ToUpper(k), s)
                        }
                }
   ```
