danbev · 2020-04-23T04:18:12Z

Currently, the following compiler warnings are generated:

../src/node_http2.cc: In static member function
‘static int node::http2::Http2Session::OnStreamClose(nghttp2_session*,
    int32_t, uint32_t, void*)’:
../src/node_http2.cc:994:16: warning:
variable ‘def’ set but not used [-Wunused-but-set-variable]
  994 |   Local<Value> def = v8::False(env->isolate());
      |                ^~~
../src/node_http2.cc: In static member function
‘static void node::http2::Http2Session::Ping(
    const v8::FunctionCallbackInfo<v8::Value>&)’:
../src/node_http2.cc:2755:16: warning:

 2755 |   Environment* env = Environment::GetCurrent(args);

../src/node_http2.cc: In static member function
‘static void node::http2::Http2Session::Settings(
const v8::FunctionCallbackInfo<v8::Value>&)’:
../src/node_http2.cc:2774:16: warning:
unused variable ‘env’ [-Wunused-variable]
 2774 |   Environment* env = Environment::GetCurrent(args);
      |                ^~~

This commit removes these unused variables.

Ugh, thank you... so annoying that the Windows build does not give the same warnings. It would definitely be good to get that PR elevating warnings into failures in CI landed

Fast track?

Sorry, I dropped the ball on this one. I've updated #32685 now and hopefully we can get it landed. We also need to add this to the CI jobs before it takes effect on all PRs.

This lands cleanly on v13.x but it's required and should not land therefore or another commit should land first. It should probably not be backported at all?
