this is my function:
func downloadDoc(c *gin.Context) {
var fileToSearch service.ApDocumentsMedia
if err := c.BindJSON(&fileToSearch); err != nil {
c.AbortWithStatusJSON(http.StatusUnprocessableEntity, "is not binding!")
return
}
var file service.ApDocumentsMedia
if err := db.Where("uuid = ?", fileToSearch.Uuid).First(&file); err.RowsAffected <= 0 {
c.IndentedJSON(http.StatusNotFound, "Document not founded!")
return
}
c.Header("Content-Description", "File Transfer")
c.Header("Content-Transfer-Encoding", "binary")
c.Header("Content-Disposition", "attachment; filename="+strconv.Quote(file.Path))
c.Header("Content-Type", "application/octet-stream; charset=utf-8")
c.File(file.Path)
c.IndentedJSON(http.StatusOK, "File inviato")
}
but then when I go to call the function (using the frontend) it gives me this error:

I'm trying to get a list of system interfaces on my machine, I'm using the net package, which is defined here.
I have this tiny little snippet of code, which crashes when trying to print out the error, and I can't figure out why the error is sigsev'ing on me. It's supposed to return an error, or nil right?
I've ran this code with sudo, root and under a regular user account thinking it might be a permissions thing for the network interface, but it persists amongst all user levels.
package main
import (
"net"
"fmt"
)
func main() {
var err error
var interfaces []net.Interface
var ifString []string
interfaces, err = net.Interfaces()
fmt.Printf("%v",interfaces)
if err != nil {
for _, v := range interfaces {
ifString = append(ifString, v.Name)
}
} else {
fmt.Printf(err.Error())
ifString = append(ifString, "unable to get system interfaces")
}
}
Program output is as follows when running go build and executing it:
[{1 65536 lo up|loopback} {2 1500 eno1 b8:cc:3c:8e:d4:d3 up|broadcast|multicast} {9 1500 tun0 up|pointtopoint|multicast}]
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x4a5269]
goroutine 1 [running]:
main.main()
/home/andrew/interface/borked.go:20 +0x269
You are receiving a nil pointer dereference because that's exactly what you're doing.
Given the following if statement in your code:
if err != nil {
for _, v := range interfaces {
ifString = append(ifString, v.Name)
}
} else {
fmt.Printf(err.Error())
...
}
The else is reached when err is nil. Yet you are attempting to access a field in it: err.Error(), dereferencing a nil pointer.
You need to invert your if statement, it's the wrong way around.
I have an issue with Go's http.Server, which I'm embedding in a struct that is supposed to control the server startup and shutdown. The struct looks like this:
type HTTPListen struct {
Consumers []pipeline.Consumer
Cfg HTTPListenConfig
Srv *http.Server
Logger log.Logger
wg *sync.WaitGroup
mu sync.Mutex
state State
}
The issue is that in my test code, I call my struct's Start() method (which in turn runs the Serve() method on the http.Server), check a few vars, and then call Stop(), whitch Shutdown()s the server and then waits for the http.Server to exit (return err from the Serve() method).
Now, for some reason, the Serve() method seems to just hang on the WaitGroup.Wait(), when I try to shutdown the server immediately after starting. When I add a short pause (tried 100ms), or when running the tests with the race detector, It works just fine.
Not sure if it matters, but there are no incoming requests between calling Serve() and Shutdown().
EDIT: link to a playground minimal example. If you comment out the time.Sleep call, the program hangs.
Here is the relevant code for the two methods:
func (h *HTTPListen) Start() error {
h.Logger.Log("msg", "starting HTTPListen input")
addr := h.Cfg.ListenAddr
ln, err := net.Listen("tcp", addr)
if err != nil {
h.Logger.Log("msg", "failed to create listener on tcp/"+addr+": "+err.Error())
h.setState(StateFailed)
return err
}
h.wg.Add(1)
go func() {
defer h.wg.Done()
err := h.Srv.Serve(ln)
h.Logger.Log("msg", "HTTP server stopped: "+err.Error())
}()
h.setState(StateStarted)
h.Logger.Log("msg", "HTTPListen input started")
return nil
}
Stop method:
func (h *HTTPListen) Stop() error {
h.Logger.Log("msg", "stopping HTTPListen input")
ctx, cancel := context.WithTimeout(context.Background(), time.Second*10)
defer cancel()
if err := h.Srv.Shutdown(ctx); err != nil {
h.Logger.Log("msg", "HTTP server shutdown deadline expired")
}
h.wg.Wait()
h.setState(StateStopped)
h.Logger.Log("msg", "HTTPListen input stopped")
return nil
}
Log output:
kwz#cyclone ~/s/stblogd> go test -v ./pkg/pipeline/input/ -run TestHTTPListen_StartStop
=== RUN TestHTTPListen_StartStop
msg="starting HTTPListen input"
msg="HTTPListen input started"
msg="stopping HTTPListen input"
... hangs indefinitely
Log output when running tests with the race detector:
kwz#cyclone ~/s/stblogd> go test -race -v ./pkg/pipeline/input/ -run TestHTTPListen_StartStop
=== RUN TestHTTPListen_StartStop
msg="starting HTTPListen input"
msg="HTTPListen input started"
msg="stopping HTTPListen input"
msg="HTTP server stopped: http: Server closed"
msg="HTTPListen input stopped"
--- PASS: TestHTTPListen_StartStop (0.00s)
PASS
ok stblogd/pkg/pipeline/input 1.007s
I'm tempted to just slap a short delay on the test and call it a day, but I would like to know why it behaves like this.
This is a known issue, see this thread:
https://github.com/golang/go/issues/20239
Hopefully they will fix it soon but for now it sounds like adding a short delay in your test is the simplest solution - it probably doesn't come up in real world use much because you won't trigger a shutdown so soon after starting.
I'm using gorethink driver, I write a query function like this in model
func GetQuotesByUser(idUser string) []Quote{
ids:=GetQuoteIdsByUser(idUser)
if (len(ids)>0){
result,err:=r.Table("quote").GetAll(ids...).Run(config.Connection())
defer result.Close()
if err!=nil{
fmt.Println(err)
return []Quote{}
}
var quotes []Quote
err=result.All("es)
if err!=nil{
fmt.Println(err)
return []Quote{}
}
fmt.Println(quotes)
return quotes
} else{
return []Quote{}
}
}
I write a route handler that calls the above function
import (
"corate/util"
"corate/model"
"github.com/fatih/structs"
"net/http"
)
func DashboardHandler(w http.ResponseWriter,r *http.Request){
files:=[]string{"base","dashboard"}
session,_:=util.GlobalSessions.SessionStart(w,r)
defer session.SessionRelease(w)
quotes:=model.GetQuotesByUser("ca8a2e14-f65b-43b1-b655-97d7c29190ec")
q:=structs.Map(quotes)
util.RenderTemplate(w,q,files...)
}
This is main function
func main(){
// Setup database
config.Setupdb()
// Initialize session manager
util.InitSessionManager()
// Serve static folder
http.Handle("/public/",http.StripPrefix("/public/",http.FileServer(http.Dir("public"))))
// Setup routers and middlewares
http.HandleFunc("/",route.IndexHandler)
http.HandleFunc("/login",route.GoogleLoginHandler)
http.HandleFunc("/auth/google",route.GoogleCallbackHandler)
http.Handle("/dashboard",negroni.New(
negroni.HandlerFunc(route.IsAuthenticated),
negroni.Wrap(http.HandlerFunc(route.DashboardHandler)),
))
// Start listening
http.ListenAndServe(":3000",nil)
}
I use astaxie/beego/session library to manage sessions for this server
import (
"github.com/astaxie/beego/session"
)
var (
GlobalSessions *session.Manager
)
func InitSessionManager() {
GlobalSessions, _ = session.NewManager("memory", `{"cookieName":"gosessionid","gclifetime":3600}`)
go GlobalSessions.GC()
}
When I start the server, and login and request to dashboard path, DashboardHandler is processed,GetQuotesByUser is called, and it works, it works, it does print out true results of query. But in browser, the browser throws error:
No data received
ERR_EMPTY_RESPONSE
The console logs some errors as well

Why does it happen? Then I notice that if I don't utilize fatih/structs library, nothing will go wrong. But I want to use that library, it will help me much. I want to know reason of this strange behavior and how to fix it while still using fatih/structs library
GetQuotesByUser returns a slice, not a struct. So you can't pass it directly to structs.Map. You'll have to iterate the slice and convert each element to a map individually.
quotes := model.GetQuotesByUser("ca8a2e14-f65b-43b1-b655-97d7c29190ec")
qs := []map[string]interface{}{}
for _, q := range quotes {
qs = append(qs, structs.Map(q))
}
util.RenderTemplate(w,qs,files...)
Should get you close to what you're after.

<input type="checkbox" name="interest" value="tennis">Tennis
Username: <input type="text" name="username">

<input type="submit" value="Login">
The panic stacktrace gives you this info :
2015/10/23 13:00:39 http: panic serving [::1]:63868: runtime error: invalid memory address or nil pointer dereference goroutine 33 [running]:
It means you're trying to access something that does not exist (nil pointer).
Then the first line that comes from your file is this one :
v8.5/duplicate_submissions/server.go:27
Which is there :
26: t, err := template.ParseFiles("templates/index.gtpl")
27: fmt.Println(err.Error())
28: err = t.Execute(w, token)
It means err is nil.
Solution
If you get the error, you cannot continue the process. That's the reason why you cannot just print out the error. In order to stop gracefully the process, you need to return an HTTP status code and then return. For the case above, you can return a code 500 (internal server error).
t, err := template.ParseFiles("templates/index.gtpl")
if err != nil {
fmt.Println(err) // Ugly debug output
w.WriteHeader(http.StatusInternalServerError) // Proper HTTP response
return
}
That has to be done for a template.ParseFiles and t.Execute too.
By the way, that is called the "comma ok" pattern

My proxyCode.lua looks like
function _M.getNewSessionID()
-- strip the sessionID length 11 cookie name before putting into the session
-- return string.sub(ngx.var.uid_set,11)
return _M.removeCookieSessionPrefixname(ngx.var.uid_set,11)
end
function _M.removeCookieSessionPrefixname(cookieName)
return string.sub(cookieName,11)
end
function _M.getIncomingAuthToken()
local cookie = ngx.req.get_headers()["Cookie"]
if (cookie ~=nil) then
local str = string.match(cookie,"AuthToken=(.*)$")
if (str ~= nil) then
return string.sub(str,11)
end
end
return nil
end
Can someone help me why i am getting this error ? i am new to Lua programming. and trying to run legacy application on my laptop.
