[英]nodejs v8.11.3 aborts in http2 with TLS if client closes session
I am hitting an issue with nodejs v8.11.3. 我遇到了nodejs v8.11.3的问题。 I am using http2 with TLS (https) and the server aborts when the client has closed the session.
我将HTTP2与TLS(https)一起使用,并且当客户端关闭会话时服务器中止。 Here is the error:
这是错误:
HTTP2 31334: Http2Session server: socket closed
HTTP2 31334: Http2Session server: marking session closed
HTTP2 31334: Http2Session server: submitting goaway

What confuses me is why does the server still emit a GOAWAY frame although the socket already was closed? 令我困惑的是,尽管套接字已经关闭,为什么服务器仍然发出GOAWAY帧?
Does anybody know some quirks to avoid the problem? 有人知道一些怪癖可以避免此问题吗?
Note: the problem does not always happen, but is reproducible as part of a more complex test scenario. 注意:问题并非总是会发生,但可以作为更复杂的测试方案的一部分重现。

I made a quirk to circumvent the problem by monkeypatching "goaway" and introduction an explicit check if the socket has been closed. 我做了一个古怪的事情,通过猴子补丁“ goaway”来解决这个问题,并引入了一个明确的检查套接字是否已关闭的方法。 TypeScript code:
TypeScript代码:
const GOAWAY = Symbol();
interface ExtServerHttp2Session extends http2.ServerHttp2Session {
[GOAWAY]?: (code?: number, lastStreamID?: number, opaqueData?: Buffer | DataView /*| TypedArray*/) => void;
}
function patchedGoaway(
this: ExtServerHttp2Session,
code?: number,
lastStreamID?: number,
opaqueData?: Buffer | DataView /*| TypedArray*/
): void {
if (!this.closed) {
this[GOAWAY]!(code, lastStreamID, opaqueData);
}
}
function monkeyPatch(session: http2.Http2Session) {
const extSession = session as ExtServerHttp2Session;
if (!extSession[GOAWAY]) {
extSession[GOAWAY] = extSession.goaway;
extSession.goaway = patchedGoaway;
}
}
Now when handling a new stream, you call monkeyPatch(stream.session)
. 现在,当处理新的流时,您可以调用
monkeyPatch(stream.session)
。
