that is causing it to hit this panic path in smallsort?

Is it possible that the rustdoc side is now doing something less determinant with floats where there wasn't before? #126761 touched the rustdoc side (cc @GuillaumeGomez) slightly after #124032 merged.

But based on that description I can't even see how the branch should ever hit, given T: Ord...

First, this code looks a bit suspect to me:

if item_ty_to_section(ty1) != item_ty_to_section(ty2)
    || (ty1 != ty2 && (ty1 == ItemType::ExternCrate || ty2 == ItemType::ExternCrate))
{
    return (reorder(ty1), idx1).cmp(&(reorder(ty2), idx2));
}

You can't just arbitrarily decide to sometimes order by type + index, and sometimes ignore it, and still expect to form a strict weak ordering.

What's even weirder is that if I look at item_ty_to_section, I believe that the above code is equivalent to the much simpler:

if ty1 != t2 {
    return reorder(ty1).cmp(&reorder(ty2));
}

which would be correct for a strict partial order. What was the intention of this branch?


Then we have the following, which is an actual Ord violation:

let s1 = i1.stability(tcx).as_ref().map(|s| s.level);
let s2 = i2.stability(tcx).as_ref().map(|s| s.level);
if let (Some(a), Some(b)) = (s1, s2) {
    match (a.is_stable(), b.is_stable()) {
        (true, true) | (false, false) => {}
        (false, true) => return Ordering::Greater,
        (true, false) => return Ordering::Less,
    }
}

Generally speaking, "order by property X if both objects have property X, otherwise ignore property X" does not form a strict weak ordering. Consider the following three objects:

type   stability   name
0      Some(2)     a
0      None        b
0      Some(1)     c

Here we simplify a bit and directly sort by type, then stability if both are Some, and then by name. Seems reasonable enough right? Nope, here you'll find that the objects with names a, b, c will sort like a < b < c < a, a clear Ord violation.


This then brings us to compare_names. This has an issue with a similar pattern:

// Then process the numeric part, if both sides have one (and they fit in a u64).
if let (Ok(ln), Ok(rn)) = (lb.parse::<u64>(), rb.parse::<u64>()) {
    match ln.cmp(&rn) {
        Ordering::Equal => (),
        x => return x,
    }
}

This violates strict weak ordering. Consider foo100000000000000000000, foo10, and foo2. The comparison function claims that foo10 < foo100000000000000000000 < foo2 < foo10.

Voultapher commented Jul 24, 2024

@workingjubilee to my knowledge this panic can only happen when the comparison function does not implement a strict weak ordering. This is usually indicative of a logic bug. The old implementation quietly accepted such cases and produced some unspecified but arguably not sorted order.

But based on that description I can't even see how the branch should ever hit, given T: Ord

I think this interpretation is something we should consider, maybe a better panic description can help avoid confusion in the future. T: Ord only says that it's implemented, not that it is implemented correctly.

@tgross35

Thanks Orson & Lukas for the detailed response. I suppose @rust-lang/rustdoc may want to take a look at a possible change here. The relevant bit was added in 2022 so I doubt anybody has any specific memory of why it exists as it currently does (#93830).

A PR to make the panic message more useful would be great, maybe even suggesting to double check T's implementation of Ord. Possibly worth a note in the docs as well.

This is very surprising. Checking what's going on.

@workingjubilee

Thank you @orlp for the entomology!

Yes, I am familiar with the "T: Ord is not actually a mathematical, compile-time-checked proof that the trait is implemented correctly" issue, and actually rather like that we now panic on violating strict weak orderings. But I couldn't quite remember what "strict weak order" was at the time I first asked. Math brain isn't up before noon, you see.

Checking again, if I understand correctly a strict weak ordering is still satisfied by most of libstd's PartialOrd impls, yes? Like floats?

@orlp

orlp commented Jul 24, 2024

@workingjubilee Strictly speaking, yes strict weak ordering corresponds with PartialOrd.

I should've been more specific and required a total order, which is also what Ord requires. A total order is a strict weak ordering where all elements must be comparable.

If something violates a strict weak ordering it also violates a total order.

@Voultapher

Voultapher commented Jul 24, 2024

Small word of caution, the docs say "If T: Ord does not implement a total order, the implementation may panic.". We do catch strict weak ordering violations in many cases, but it's not guaranteed. One thing I like about our implementation in contrast to for example the recently added libc++ std::sort strict weak ordering checks, the libc++ one works by consuming a fixed number of comparison at the very start (20/50) IIRC and running a O(N^3) check algorithm on them, but only for debug builds. In contrast our implementation sits at the heart of the small-sort and notices issues that were caused by some higher level components, this way it holistically works for the hole input, catching violations with a high chance, plus it serves dual purpose as a safety safeguard that lets us avoid additional state tracking complexity, bailing before committing the faulty merge result. There are cases where this logic isn't used at all e.g. len <= 20, non Freeze types.

Is it possible to get these changes into the 1.81 release? It doesn't change behavior and would greatly help when users encounter this panic for the first time, which they may after upgrading to 1.81.
