mime: ParseMediaType parses invalid media types (original) (raw)

The following program fails with the panic:

package main

import ( "mime" "fmt" )

func main() { sdata := "0" mt, params, err := mime.ParseMediaType(sdata) if err != nil { return } sdata1 := mime.FormatMediaType(mt, params) _, _, err = mime.ParseMediaType(sdata1) if err != nil { fmt.Printf("%q(%q, %+v) -> %q\n", sdata, mt, params, sdata1) panic(err) } }

"0"("0", map[]) -> ""
panic: mime: no media type

If "0" is not a valid mediatype, then the first ParseMediaType should produce an error.
