How to reproduce

package main

import (
    "github.com/gin-gonic/gin"
    "net/http"
)

func main() {
    r := gin.Default()
    r.GET("/ping", func(c *gin.Context) {
        c.JSON(http.StatusOK, gin.H{
            "message": "pong",
        })
    })
    file := "/tmp/testgin.sock"
    //os.Remove(file)
    r.RunUnix(file)
}

Environment

• go version: v1.20.3
• gin version (or commit ref): v1.9.1
• operating system: osx, ubuntu

The socket should instead be cleaned up at shutdown.

It creates the sock file but does not delete it after Ctrl + C or stop by supervisord. defer os.Remove(file) not executed.

Maybe I should handle this situation manually?

I don't think you should have to, if the service is not running anymore, the socket should disappear imo.
