From 45fbdec453bbc53454d373c1d4ae9c5569fb539c Mon Sep 17 00:00:00 2001 From: Haruue Icymoon Date: Sun, 28 Aug 2022 20:25:50 +0800 Subject: [PATCH] chore: swap the const value of server hello reply by setting StatusTCPOnly == 1, when a new version client connect to an old version server, the client will treat the server as udp disabled and will not submit a udp request or open a udp control stream. this make the upgrade much more smoothly even if we don't change the protocolVersion. --- pkg/core/protocol.go | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/pkg/core/protocol.go b/pkg/core/protocol.go index 17a0b57..df53e9e 100644 --- a/pkg/core/protocol.go +++ b/pkg/core/protocol.go @@ -27,8 +27,8 @@ type clientHello struct { const ( serverHelloStatusFailed = uint8(0) - serverHelloStatusOK = uint8(1) - serverHelloStatusTCPOnly = uint8(2) + serverHelloStatusTCPOnly = uint8(1) + serverHelloStatusOK = uint8(2) ) type serverHello struct {
