fs.mkdir with recursive option and invalid name hangs the program

[GeorgianStan]

• Version: v12.18.0
• Platform: Windows10
• Subsystem:

What steps will reproduce the bug?

const fs = require("fs");
const path = "./to-delete/s:d";

fs.mkdir(path, { recursive: true }, (err) => {
  if (err) {
    console.log(err);
    return;
  }
  console.log("success");
});

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

Using : (double dots) character in folder name after the first prefix will make the program freeze

What is the expected behavior?

Throw an error

What do you see instead?

The program hangs

I'm not able to test it on linux. I've only tested it in Windows 10

Can you test with the latest 12.x version? I remember this issue and I think it was fixed recently .

[GeorgianStan]

I tested against Node v14.15.1. Same problem

[Xstoudi]

I can confirm it happens on v12.20.0 and v14.15.1.

[targos]

It seems to be the same issue as #31177.
libuv/libuv#2601 is supposed to fix it.

[Xstoudi]

The fix landed yesterday in libuv: libuv/libuv@dd8662b

[GeorgianStan]

Thank you. In what version is the fix available?

[jasnell]

Can confirm that the issue has been fixed in the 15.x line at least. Not sure about 14.x or 12.x.
