net/http: documentation for interaction between http2 imported and http pkgs.

[gaillard]

Just requesting some documentation for the case when someone does something like

hs := &http.Server{Handler: thehandler}
if err := http2.ConfigureServer(hs, &http2.Server{}); err != nil {
    //handle
}
if err := hs.Serve(existingTLSListener); err != nil {
    //handle
}

and has therefore vendored in the http2 package. How does this interact with the bundled http2 in the http package?

[gaillard]

Any kind of one sentence answer here before documentation is worked on would be highly valued if anyone has the time

If you import golang.org/x/net/http2 and use it to register the client or server, the (presumably newer) http2 package you imported wins.

The bundled copy is only used as a default.

[gaillard]

Much appreciated, but which in the example above is doing the "registering"?

[bradfitz]

http2.ConfigureServer
