QUESTION

Go migrate will not install on MacOS

Asked 2020-Sep-25 at 14:16

Mac OS here. I have Go version go1.14.2 darwin/amd64 installed locally under ~/go and in my ~/.bash_profile I have:

export PATH=$PATH:/usr/local/go/bin
export PATH=$PATH:/Users/myuser/workspace/myproject/repos
export PATH="$GOPATH/bin:$PATH"

export GOPATH=/Users/myuser/workspace/myproject/repos

export PATH=$PATH:/Users/myuser/workspace/myproject/repos/bin

I am trying to get go migrate working. When I run:

go get -tags 'postgres' -u github.com/golang-migrate/migrate/v4/cmd/migrate

I get:

$ go migrate
go migrate: unknown command

So then I tried downloading the binary directly off of GitHub and have copied it to /Users/myuser/workspace/myproject/repos/bin/:

$ ls -al ~/myuser/myproject/repos/bin/

But still, when I run go migrate I get errors:

$ go migrate
go migrate: unknown command

Given where I have Go downloaded and all my path settings, which I really don't want to change, how can I install go migrate successfully and make it work from the command line?

When I run:

$ which migrate
$

So it is not installed.

It's actually called migrate, you can check its location by running which migrate or command -v migrate, or call binary from your bin folder migrate.darwin-amd64

QUESTION

code-generator is not getting downloaded to vendor folder

Asked 2020-May-25 at 17:32

I am trying to create a CRD following the instructions here + using go modules.

My go.mod looks like this:

module github.com/v*****va/kustred

go 1.14

require (
        github.com/golangci/golangci-lint v1.25.0 // indirect
        github.com/google/go-cmp v0.4.0 // indirect
        github.com/json-iterator/go v1.1.9 // indirect
        github.com/kr/pretty v0.2.0 // indirect
        golang.org/x/net v0.0.0-20200520182314-0ba52f642ac2 // indirect
        gopkg.in/yaml.v2 v2.3.0 // indirect
        gotest.tools/gotestsum v0.4.2 // indirect
        k8s.io/apimachinery v0.18.3
        k8s.io/code-generator v0.18.3 // indirect
)

After I ran go mod vendor, I looked at the contents of vendor/k8s.io/, I see that only apimachinery and klog are present, code-generator is missing. I am not sure about relevance of vendor.moudles.txt but there is a line about code-generator commented out.

Am i missing something?

ANSWER

Answered 2020-May-25 at 17:32

It's indirect in this module file, so probably not needed (not imported by your code). That's why it's unnecessary to vendor.

It's tracked because it's a dependency of your machinery dependency but actually packages you're using from machinery don't need packages from code-generator.

If you want to vendor it explicitly, you can do a blank import somewhere in your code such that

import _ "k8s.io/code-generator"

QUESTION

Unable to read variables from a url using gorilla mux in golang

Asked 2020-Jan-22 at 06:20

I am trying to write a unit test using gotests and gomock to my restful service written in golang using gorilla but service fails to get variables from the url

Here is my request

req, err := http.NewRequest("GET", "product/5b5758f9931653c36bcaf0a0", nil)

actual endpoint is product/{id}

when I step into my service at the below code

params := mux.Vars(req)

params map is empty when it should have id key mapped to 5b5758f9931653c36bcaf0a0

Strange part is endpoint works fine from post man.

May I know whats wrong with the request?

ANSWER

Answered 2018-Jul-25 at 19:17

Since you're using GET requests, you can use the http.Get function, it works as expected:

package main

import (
    "fmt"
    "net/http"

    "github.com/gorilla/mux"
)

func handle(w http.ResponseWriter, r *http.Request) {
    params := mux.Vars(r)
    fmt.Println(params)
}

func main() {
    m := mux.NewRouter()
    m.HandleFunc("/products/{id}", handle)
    http.Handle("/", m)
    go func() {
        http.ListenAndServe(":8080", nil)
    }()
    _, err := http.Get("http://localhost:8080/products/765")
    // Handle Error
}

If you really want to use http.NewRequest, that function doesn't actually execute the request so here is what you would need:

req, err := http.NewRequest("GET", "product/5b5758f9931653c36bcaf0a0", nil)
client := &http.Client{}
client.Do(req)

Some tools are able to install, others are not. I can't do anything about the Not a git repository error because it's an automated process and I'm not the one typing the git commands.

I tried installing the tools separately in PowerShell and I get the same errors. My go directory is created (in %USERPROFILE%\go) and the GOPATH is set correctly.

Any ideas ?

Answered 2017-Mar-25 at 17:23

It looks like it's complaining due to C:\Users\user\go\src\golang.org\x\tools being not a git repo, so it can't update whatever is in it.

Assuming you didn't put your own code in that dir, try removing it and then running again.

If you look at the docs for the Go plugin, and scroll all the way to the bottom, it shows the commands to run if you want to manually install/upgrade the stuff the plugin needs.

Specifically, taken from their github repo, you can just run this from a cmd.exe prompt.

My DSN connection string includes ?multiStatements=true&sql_mode=TRADITIONAL.

I'm hoping I just do not understand how DB.Exec args interpolation / placeholder works, but I am finding it difficult to find examples.

The answer was to set interpolate params to true. https://github.com/go-sql-driver/mysql#interpolateparams

QUESTION

golang how to live test an http server?

Asked 2017-Nov-21 at 08:45

I use gotests, and gorilla mux and I can unit test my http handlefunc handlers, but they do not respond to the proper http request methods as they should under the gorilla mux. How I can do a "live server" version of the test?

func main() {
    router := mux.NewRouter()
    router.HandleFunc("/", views.Index).Methods("GET")
}

func Index(w http.ResponseWriter, r *http.Request) {
    w.Header().Set("Content-Type", "application/json; charset=UTF-8")
    w.WriteHeader(http.StatusOK)

    fmt.Fprintf(w, "INDEX\n")
}

func TestIndex(t *testing.T) {

    req, _ := http.NewRequest("GET", "/", nil)
    req1, _ := http.NewRequest("POST", "/", nil)
    rr := httptest.NewRecorder()

    handler := http.HandlerFunc(Index)

    type args struct {
        w http.ResponseWriter
        r *http.Request
    }
    tests := []struct {
        name string
        args args
    }{
        {name: "1: testing get", args: args{w: rr, r: req}},
        {name: "2: testing post", args: args{w: rr, r: req1}},
    }
    for _, tt := range tests {
        t.Run(tt.name, func(t *testing.T) {
            handler.ServeHTTP(tt.args.w, tt.args.r)
            log.Println(tt.args.w)
        })
    }
}

The problem here is that the function responds to both the get and post requests and doens't take into account my main router. This is fine for unit testing the function, but I think it would be better to just write an integrated test that tests the whole thing and gets everything out of the way in one go.

Use the net/http/httptest.Server type to test with a live server.

func TestIndex(t *testing.T) {
  // Create server using the a router initialized elsewhere. The router
  // can be a Gorilla mux as in the question, a net/http ServeMux, 
  // http.DefaultServeMux or any value that statisfies the net/http
  // Handler interface.
  ts := httptest.NewServer(router)  
  defer ts.Close()

  newreq := func(method, url string, body io.Reader) *http.Request {
    r, err := http.NewRequest(method, url, body)
    if err != nil {
        t.Fatal(err)
    }
    return r
  }

  tests := []struct {
    name string
    r    *http.Request
  }{
    {name: "1: testing get", r: newreq("GET", ts.URL+"/", nil)},
    {name: "2: testing post", r: newreq("POST", ts.URL+"/", nil)}, // reader argument required for POST
  }
  for _, tt := range tests {
    t.Run(tt.name, func(t *testing.T) {
        resp, err := http.DefaultClient.Do(tt.r)
        defer resp.Body.Close()
        if err != nil {
            t.Fatal(err)
        }
        // check for expected response here.
    })
  }
}

Although the question uses Gorilla mux, the approach and details in this answer apply to any router that satisfies the http.Handler interface.
