From 0df602afed31954086a54b67e1e2c53672aef7d8 Mon Sep 17 00:00:00 2001 From: Fabio Alessandrelli Date: Sat, 23 Nov 2024 14:57:24 +0100 Subject: [UPNP] Allow disabling UPNP implementation on the Web Make UPNP classes custom instance, so they can come with empty implementation on the Web (where the would not work anyway) without breaking scripts referencing it. This results in smaller Web builds by not including the library which also results in the emscripten socket wrappers to be stipped away. --- modules/upnp/upnp.cpp | 299 +------------------------------------------------- 1 file changed, 1 insertion(+), 298 deletions(-) (limited to 'modules/upnp/upnp.cpp') diff --git a/modules/upnp/upnp.cpp b/modules/upnp/upnp.cpp index 4305bf842a..5ec0b984fc 100644 --- a/modules/upnp/upnp.cpp +++ b/modules/upnp/upnp.cpp @@ -30,298 +30,7 @@ #include "upnp.h" -#include -#include - -#include - -bool UPNP::is_common_device(const String &dev) const { - return dev.is_empty() || - dev.contains("InternetGatewayDevice") || - dev.contains("WANIPConnection") || - dev.contains("WANPPPConnection") || - dev.contains("rootdevice");
