Re: [go-nuts] Remove path from error messages
Hi and Thanks Peter for your reply! I have compiled this on my mac, and am
running it on a linux system. I compile it like this:
GOOS=linux GOARCH=amd64 go build -o binaries/linux64/mysqlrun mysqlrun.go
Then I copy that binary to the server I am running it on and if there is an
error -- it spits out an error message containing the path and the line
number. I've notice this happens with any program. OK this is only an
example to show the error message. If you've got a program:
package main
import (
"fmt"
"strconv"
)
func main() {
var divByS string
fmt.Println("What do you want to divide by?")
fmt.Printf("Number: ")
fmt.Scanln()
fmt.Println("Great, divide 100 by " + divByS)
divBy, err := strconv.Atoi(divByS)
if err != nil {
fmt.Printf("OOOpps %v\n", err)
}
x := 100 / divBy
fmt.Println(x)
}
yes I know it's easy to catch a divide by zero, but it's to show the
error... When I run this:
What do you want to divide by?
Number: 0
Great, divide 100 by 0
panic: runtime error: integer divide by zero
goroutine 1 [running]:
main.main()
/Users/rich/go/test.go:18 +0x2cf
I don't want the highlighted part to print.

Re: [go-nuts] Remove path from error messages
Error messages don't include any contextual information by default. If the path to a Go file is in there, it's because whatever created the error message (or modified it at some point) put it there. Where is that error created, and what touches it as it flows through the call stack to the logging statement that prints it to the screen? Don't forget to also check the logging package itself, which can sometimes annotate with caller information. Trace that out, and you'll find your answer.

[go-nuts] Remove path from error messages
I apologize if this has been asked before but I searched google and this group and didn't find it. How do you remove the path from the error messages? So I have a valid error: 2018/10/16 18:13:12 [error] in main.checkMaster[/Users/rich/go/mysqlrun/mysqlrun.go:739] Error 1045: Access denied for user How do I get rid of the part highlighted above? It's a valid error. The user specified the wrong password so I want the error -- I just don't want the path part as a part of that error. This happens any time there is an error in a script, it prints out information about the author that I don't particularly want published.
