Stream finished does not always work with http incoming message

• Version: v15.12.0
• Platform: Darwin Kernel Version 20.3.0
• Subsystem: http

What steps will reproduce the bug?

The stream.finished never resolves or rejects when applied onto a destroyed incoming message like in example below. It finishes for example when applied on a destroyed file stream. Also it finishes when the line with await new Promise(r => setTimeout(r, 1000)); is commented. This looks really inconsistent.

let http = require("http");
let { finished } = require("stream/promises");

let server = http.createServer(async function(req, res)
{
	for await (let chunk of req) break;
	await new Promise(r => setTimeout(r, 1000));
	console.log("waiting");
	await finished(req);
	console.log("sending");
	res.end();
});

(async function()
{
	await new Promise(resolve => server.listen(resolve));
	let req = http.request({ port: server.address().port, method: "post" }).end("abc");
	try
	{
		let res = await new Promise((resolve, reject) => req.on("response", resolve).on("error", reject));
		await finished(res.resume());
	}
	catch(e)
	{
		console.log(e);
	}
}());

How often does it reproduce? Is there a required condition?

Always.

What is the expected behavior?

Error: socket hang up
waiting
sending

What do you see instead?

Error: socket hang up
waiting

Additional information

Commencez par exécuter la reproduction fournie de http.createServer sur Node v15.12.0 et suivre l’interaction entre la requête entrante, la fonction finished de stream/promises et le await différé. Comparez le comportement de la requête détruite avec celui du flux de fichier présenté dans le rapport. C’est terminé lorsque la reproduction atteint "sending" et produit la sortie socket hang-up attendue.
