{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Stream finished does not always work with http incoming message","articleBody":"* **Version**: v15.12.0\n* **Platform**: Darwin Kernel Version 20.3.0\n* **Subsystem**: http\n\n### What steps will reproduce the bug?\n\nThe `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.\n\n``` js\nlet http = require(\"http\");\nlet { finished } = require(\"stream/promises\");\n\nlet server = http.createServer(async function(req, res)\n{\n\tfor await (let chunk of req) break;\n\tawait new Promise(r => setTimeout(r, 1000));\n\tconsole.log(\"waiting\");\n\tawait finished(req);\n\tconsole.log(\"sending\");\n\tres.end();\n});\n\n(async function()\n{\n\tawait new Promise(resolve => server.listen(resolve));\n\tlet req = http.request({ port: server.address().port, method: \"post\" }).end(\"abc\");\n\ttry\n\t{\n\t\tlet res = await new Promise((resolve, reject) => req.on(\"response\", resolve).on(\"error\", reject));\n\t\tawait finished(res.resume());\n\t}\n\tcatch(e)\n\t{\n\t\tconsole.log(e);\n\t}\n}());\n```\n\n### How often does it reproduce? Is there a required condition?\n\nAlways.\n\n### What is the expected behavior?\n\n```\nError: socket hang up\nwaiting\nsending\n```\n\n### What do you see instead?\n\n```\nError: socket hang up\nwaiting\n```\n","author":{"url":"https://github.com/misos1","@type":"Person","name":"misos1"},"datePublished":"2021-05-12T19:46:57Z","url":"https://github.com/nodejs/node/issues/38657"}
