…port (#23686) Precursor to #23236 This implements the SNI features, but uses private symbols to avoid exposing the functionality at this time. Note that to properly test this feature, we need to add a way for `connectTls` to specify a hostname. This is something that should be pushed into that API at a later time as well. ```ts Deno.test( { permissions: { net: true, read: true } }, async function listenResolver() { let sniRequests = []; const listener = Deno.listenTls({ hostname: "localhost", port: 0, [resolverSymbol]: (sni: string) => { sniRequests.push(sni); return { cert, key, }; }, }); { const conn = await Deno.connectTls({ hostname: "localhost", [serverNameSymbol]: "server-1", port: listener.addr.port, }); const [_handshake, serverConn] = await Promise.all([ conn.handshake(), listener.accept(), ]); conn.close(); serverConn.close(); } { const conn = await Deno.connectTls({ hostname: "localhost", [serverNameSymbol]: "server-2", port: listener.addr.port, }); const [_handshake, serverConn] = await Promise.all([ conn.handshake(), listener.accept(), ]); conn.close(); serverConn.close(); } assertEquals(sniRequests, ["server-1", "server-2"]); listener.close(); }, ); ``` --------- Signed-off-by: Matt Mastracci <matthew@mastracci.com>
