I don't think this is the same thing. after I send out a too big UDP and receive the ICMP need fragment error, I can use MSG_ERRQUEUE flag to receive the mtu info from the same UDP socket. the icmp package only works when you send out a icmp package. 在 2017年7月15日星期六 UTC+8上午9:40:38，Matt Har

Re: [go-nuts] Help with mapping XML to struct

The sample document you gave actually doesn't have any attributes at all. I guess you meant namespaces? Are you leaving out the namespace declarations from your sample? They usually look like xmlns:soapenv="http://some_url";. Those are important to parsing with namespaces in Go. If you don't have

Re: [go-nuts] Re: http.Server.Shutdown() crashing?

The reason it was exiting was because you didn't wait at the end of main() after http.ListenAndServe exited. ListenAndServe will exit as soon as the listening socket is closed, but there can still be connected sockets open at that time (including the one handling /stop). When main returns, the Go p

If the type of the map is map[string]interface{}, it can be used with either type of template. https://play.golang.org/p/-sFMhKOtNN If you create your own template type, then you can also create your own FuncMap type, and in your own Funcs method, pass it on to the underlying template: type FuncM

The reason why using select instead ok-comma is because I don't one upstream to block another. Using blocking ok-comma is ok when upstreams are fast. However, when one is slow, others could starve. On Friday, July 14, 2017 at 12:46:27 PM UTC+8, Ian Lance Taylor wrote: > > On Thu, Jul 13, 2017 at
