### Version v19.2.0, v14.21.1 ### Platform Linux wolf-x1c6 5.15.0-53-generic #59-Ubuntu SMP Mon Oct 17 18:53:30 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux ### Subsystem _No response_ ### What steps will reproduce the bug? ```js import fsPromises from 'node:fs/promises' const fh = await fsPromises.open('example.txt') fh.on('close', () => {throw new Error('handle closed!')}) const stream = fh.createReadStream({ autoClose: false, }) for await (const chunk of stream) { break } // Give the event loop a breather: this seems to be where the close happens await new Promise(resolve => setTimeout(resolve, 10)) console.log('fd', fh.fd) // = -1; stream closed ``` ### How often does it reproduce? Is there a required condition? Always ### What is the expected behavior? `FileHandle.createReadStream({autoClose: false})` should result in the file handle not being automatically closed when the stream is destroyed. ### What do you see instead? Using `fs.ReadStream[Symbol.asyncIterator]` seems to unconditionally close the file handle (after a small delay; I guess at the end of the event loop or something? but haven't dug in; just noted the `setTimeout` above is necessary to reproduce) despite `{autoClose: false}` being passed to `FileHandle.createReadStream()`. This seems to be the result of the underlying `readable.destroy()` also closing the file handle; but it means that, as far as I can tell, there's no way to only partially consume an `fs.ReadStream` created from a file handle without either closing the handle or leaking the stream. ### Additional information _No response_
