[go-nuts] Having trouble in running a go-git api example
Hi, I am trying to run example provided here(https://github.com/go-git/go-git/tree/master/_examples) 1) firstly I run the clone example by cloning a repo(https://github.com/go-git/go-git/blob/master/_examples/clone/auth/basic/access_token/main.go). (it was successful) 2) Then I run the commit example by creating a file.(https://github.com/go-git/go-git/blob/master/_examples/commit/main.go) it was successful. 3) Now I want to push that file to git repo. but I am not able to understand what argument i should give along with the go executable file.(https://github.com/go-git/go-git/blob/master/_examples/push/main.go) Can anyone please help me this.

I don't think we want to lock ourselves into the current behavior if
we can avoid it. We may find reasons to change it over time.
(That said I wouldn't be surprised if changing this behavior broke
some people's use cases.)

IINM, if the last field of a Go struct has zero size the struct is
extended by at least one byte to prevent taking the address of the
zero sized field that could be outside of the allocated memory area
for the instance of C. (That could, for example, make the precision garbage
collector consider the following memory block reachable when it is not.)
If that's the case then the definition above is actually laid out as
type C struct {
Pre uint64
Inner byte
}
Note that the flexible array member concept of C is in most cases not
compatible with memory managed
by the Go runtime as described in the documentation for package unsafe. It
should be fine in memory
not managed by the Go runtime, though.

[go-nuts] JWT Updated and ask for advice
Hi good afternoon golang dev's, I'm starting in golang blogs and I don't
where to post this kind of questions,
Learning fiber framework and JWT Auth I'm getting in the register Func and
Login Func the user Id is saving correctly on DB. The cookie and JWT are
getting correctly and disply the cookie and preseve on the frontEnd, but
when I want to get the login UserId on Controller I got 0 did some one
know's what is happening?
I leave the code hopping have some orientation.
Jwt has been updated and I’m confuse.
```
// Midleware:
const SecretKey = "secret"
func IsAuthenticated(c *fiber.Ctx) error {
cookie := c.Cookies("jwt")
token, err := jwt.ParseWithClaims(cookie, &jwt.RegisteredClaims{},
func(token *jwt.Token)
(interface{}, error) {
return []byte(SecretKey), nil
})
if err != nil || !token.Valid {
c.Status(fiber.StatusUnauthorized)
return c.JSON(fiber.Map{
"message": "unauthenticated",
})
}
return c.Next()
}
func GetUserId(c *fiber.Ctx) (uint, error) {
cookie := c.Cookies("jwt")
log.Println("Cookie .: ", cookie)
token, err := jwt.ParseWithClaims(cookie, &jwt.RegisteredClaims{},
func(token *jwt.Token)
(interface{}, error) {
return []byte(SecretKey), nil
})
log.Println("Token .: ", token)
log.Println("Error .: ", err)
if err != nil {
return 0, err
}
// var user dto.User
// expireTime := time.Now().Add(24 * time.Hour)
// payloads := jwt.RegisteredClaims{
// Subject: strconv.Itoa(int(user.Id)),
// ExpiresAt: &jwt.NumericDate{Time: expireTime},
// }
payload := token.Claims.(*jwt.RegisteredClaims)
id, _ := strconv.Atoi(payload.Subject)
return uint(id), nil
}
func GenerateJWT(id uint) (string, error) {
expireTime := time.Now().Add(24 * time.Hour)
var user dto.User
token, err := jwt.NewWithClaims(jwt.SigningMethodHS256,
jwt.RegisteredClaims{
Subject: strconv.Itoa(int(user.Id)),
ExpiresAt: &jwt.NumericDate{Time: expireTime},
}).SignedString([]byte(SecretKey))
if err != nil {
log.Println(err)
}
return token, err
}
//Controller:
func User(c *fiber.Ctx) error {
var user dto.User
id, err := middlewares.GetUserId(c)

[go-nuts] Tracking which connection is used to make an HTTP request
I have created an http.Client with a custom TLS dialer. The custom TLS
dialer creates a *tls.Conn and while doing this, it logs out a lot of
information such as which server is used.
Now, when I make an HTTP request, I want to log out which dial produced the
*tls.Conn the HTTP request ended up using.
Using httptrace.ClientTrace.GotConn it is possible to get the net.Conn that
was used by the request. But how do I relate that with which dial was used
to create it?
I see four options but they all have drawbacks:
1) I can keep a map from net.Conn to information that identifies the dial.
But when can I delete entries from this map? Go does not have weak pointers.
2) I can make a my own struct and return from my custom dialer:
type myConn struct {
net.Conn
dialInfo string
}
However, that does not work well for TLS. The reason is that the Go HTTP
client has special logic in case a custom dialer returns a *tls.Conn. That
logic will be disabled.
3) I can log out the address of the net.Conn object both from my custom
dialer and from GotConn. I can do that by using something like
reflect.ValueOf(conn).Pointer(). However in practice it seems like
different net.Conn objects can easily get the same address.
4) I can log out the local and remote IP addresses and port of the net.Conn
both from the dialer and from GotConn. It is a lot of information and
different connections may use the same IP and ports. But maybe the best I
can do?
Any other ideas?

[go-nuts] Zero-sized data type
Hi, I am looking for zero-sized data type, something like Flexible Array
Member.
The size of `struct {}` is indeed zero, but for what reason when it's
inside a struct with another member say (https://go.dev/play/p/DpydJIke7dS):
type C struct {
Pre uint64
Inner struct{}
}
That struct sized for 16, while the sum of all member sizes is only 8, it's
like there's hidden padding/align.
Thanks!

Re: [go-nuts] workspace question
Thank you, Jan. Apparently where I went wrong was assuming that the
dependency had to be listed in go.mod. (i.e., using the names from your
example, foo/go.mod needed to have a "require bar" in it). That is what I
was struggling to achieve; it never occurred to me that it could be
omitted. I'm still surprised it works without that; it seems weird to have
a dependency on another module and *not* list it with all of the other
dependencies.
At any rate, I have it working now based on your help — much appreciated.

[go-nuts] go:embed question
I know that //go:embed directive reads the content of the embedable file at compile time. Now if that's the case I wondering if you are running a Go executable with "go run" at the same time while you are downloading like go run github.com/user/projectname@latest (which should embed an external file) why the file is not embedded? Normally if the file you want to embed does not exits, the compiler will throw you an error telling that "no matching files found". Why is not the case when you are running without a prior download? I'm asking this because if I'm running the application normally the file is getting embedded correctly, but if I'm trying to build it on-the-fly with go run this is not happening? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
