net/http: can't send star request

[dvyukov]

The following program fails with the panic:

package main

import (
    "bufio"
    "bytes"
    "net/http"
)

func main() {
    data := []byte("M-SEARCH * HTTP/1.1\n\n")
    r, err := http.ReadRequest(bufio.NewReader(bytes.NewReader(data)))
    if err != nil {
        return
    }
    buf := new(bytes.Buffer)
    if err := r.Write(buf); err != nil {
        return
    }
    _, err = http.ReadRequest(bufio.NewReader(buf))
    if err != nil {
        panic(err)
    }
}

panic: parse %2A: invalid URI for request

Star is a common path for some request types. It is handled by a special path in URL.Parse, but URL.String generated %2A for it, which is an invalid path.
