That's a good sign (for security) [i think] Do CIs now need approving reviews? 🎉 |

They don't strictly need it. Collaborators can still start CI jobs from Jenkins. |

Looks good overall, the only benchmark with significant performance impact is path/toNamespacedPath-posix.js.
IMHO it's good enough to land as is.
For context, originally path.posix.toNamespacedPath() is a noop. I doubt that this function is popular in userspace, but it's heavily used in Node.js internals (mostly in pair with getValidatedPath(), and in internal/modules).
There is an opened PR moving most of it to c++ (#52135) that should disconnect fs from performance impacts for js version of toNamespacedPath().
Alternatively on js side, I think we can reduce performance penalty in internals by introducing two versions of toNamespacedPath(): internal API without URL support and as public API with it.
@anonrig WDYT?

While the performance impact seems significant, I don't think it'll be noticeable (but I haven't tested it yet for the actual MS timings). It's just an extra As @LiviaMedeiros said, I could also make an internal function for it to be used in the internals. |
|
Can we run the benchmarks of file system operations? I don't think 20% is a cost that is acceptable. |

Should we add an error hint where if someone calls a path method with a string URL (not an URL instance) we suggest that they wrap their input in new URL? Basically if we’re about to throw anyway, if the input started with file: then enrich the error with this suggestion.

The 2 referenced issues are 2 years old and 9 months old that didn't receive as much traffic to warrant for this change in an extremely important part of the Node.js core.
I prefer this function to not change the signature of the existing functions, if the request/need for the change is not warranting the cost of touching an extremely hot path. We might expose a different function that we don't rely on (internally), but I'm not sure.
I'm -1 on the proposed change as it is.

I am not convinced that this is a step in the right direction.
For example, isn't the second argument of the URL constructor supposed to effectively do resolve() (with the typical URL caveats)?
On a related note, normalize() has a variety of issues because the resulting path is not necessary equivalent to the original path. Explicitly propagating these quirks to file URLs feels odd to me.
