This is a new incremental compilation issue, distinct from the previous 'called Option::unwrap' issues. cc @cjgillot

[Aaron1011]

Thanks for the great reproducer - I was able to reproduce this by first building commit 27f1892baf487c61390b61d14f96b7828bd5e660, then building commit znx3p0/canary@1920c7e

[Aaron1011]

This is caused by the way that we handle DepKind::TraitSelect (which is an anon dep-node).

The current query system is set up so that we will never try to force a query with a stale DefPathHash. Normally, the only way of invoking a query with a DefId is to obtain that DefId from another query result, or to receive that DefId as part of the query argument.

If a query 'A' obtains a DefId by invoking another query 'B', then removing the corresponding definition from the crate will change the result of query 'B', causing it to be marked red. When we try to mark query 'A' as green, we will see the red dependency 'B' and bail out, before we ever attempt to force another query with the stale DefPathHash that we saved from the previous compilation session.

When we actually invoke a query during the execution of some query's body, we will try to find a matching DepNode from the previous compilation session. If the input to the invoked query contains a DefId (e.g. as part of the AdtDef inside of a Ty), then a change to the DefPathHash will cause us to compute a different hash for the query input. As a result, we will never try to load the depnode from a previous session, since we will not find a node with a matching hash.

However, anon dep nodes break this assumption. Specifically, when we create a DepKind::TraitSelect, we invoke queries like type_of using DefIds taken from the surrounding SelectionContext. From the perspective of the query system, these DefIds are essentially pulled out of thin air - the query system sees DepKind::TraitSelect as having no input. Specifically, we call:

rust/compiler/rustc_trait_selection/src/traits/select/mod.rs

Line 756 in fd20513

let (result, dep_node) = self.in_task(|this| this.evaluate_stack(&stack));

Inside a (recursive) call to evaluate_stack, we may call queries with DefIds obtained from the predicate - for example, to look up constituent types for auto trait impls.

As a result, trying to mark a TraitSelect node green can cause us to try to force a query with a stale DefPathHash, since our edges vec will not contain a dependency on a query used to produce the DefPathHash to begin with. With normal non-anon nodes, the dependency on a particular DefId will always be explicitly carried through the graph of query invocations - either being forwarded through a query argument (thus affecting the DepNode hash), or by using the result of another query.

The fact that we will never legitimately try to force a stale DefPathHash has helped us find bugs (e.g. #91696 (comment)), so I think it would be unfortunate if we had to start silently ignoring the forcing of a stale DefPathHash.

I'll need to think about how we can adjust anon dep nodes to fix this issue. Ideally, we would just remove the concept of anon dep nodes entirely - however, I'm pretty sure that it's the only way to make the global evaluation cache work with incremental compilation.

[Aaron1011]

I've determined the root cause of the issue - we're failing to keep track of the created DepNode when using the provisional cache. When evaluation finishes 'normally', we store the created anon TraitSelect depnode into the evaluation cache:

rust/compiler/rustc_trait_selection/src/traits/select/mod.rs

Lines 765 to 766 in ee5d8d3

	debug!(?result, "CACHE MISS");
	self.insert_evaluation_cache(param_env, fresh_trait_pred, dep_node, result);

When we later read from the evaluation cache, we will generate a read of that DepNode:

rust/compiler/rustc_query_system/src/cache.rs

Lines 49 to 52 in ee5d8d3

	pub fn get<CTX: DepContext>(&self, tcx: CTX) -> T {
	tcx.dep_graph().read_index(self.dep_node);
	self.cached_value.clone()
	}

This ensures that any queries using a cached result will still get all of the dependency edges created during the initial uncached execution (e.g. a call to type_of when determining constituent types).

However, when we store a result in the provisional cache (due to an auto-trait cycle), we don't store the generated DepNode:

rust/compiler/rustc_trait_selection/src/traits/select/mod.rs

Lines 776 to 785 in ee5d8d3

	} else {
	debug!(?result, "PROVISIONAL");
	debug!(
	"caching provisionally because {:?} \
	is a cycle participant (at depth {}, reached depth {})",
	fresh_trait_pred, stack.depth, reached_depth,
	);
	stack.cache().insert_provisional(stack.dfn, reached_depth, fresh_trait_pred, result);
	}

When we later move entires from the provisional cache to the 'real' evaluation cache, we insert them using a different DepNode:

rust/compiler/rustc_trait_selection/src/traits/select/mod.rs

Lines 768 to 775 in ee5d8d3

	stack.cache().on_completion(stack.dfn, |fresh_trait_pred, provisional_result| {
	self.insert_evaluation_cache(
	param_env,
	fresh_trait_pred,
	dep_node,
	provisional_result.max(result),
	);
	});

In the provided reproducer, we first store routes::Storable: core::marker::Send in the provisional cache, and then move it to the 'real' evaluation cache. This means that any queries using the cached result of evaluating routes::Storable: core::marker::Send (e.g. a call to evaluate_obligation) will not get dependency edges added for any queries invoked during the initial 'provisional' evaluation of the predicate. In particular, we will not get the edge to type_of(canary[57e4]::routes::Storable::Route::0), which has a changed result between the two compilation sessions.

I've confirmed that storing the provisional result into the evaluation cache using its original DepNodeIndex fixes the ICE. However, I need to do some more investigation - I think we may need to combine both DepNodeIndex's to ensure that we don't miss any edges.

Minimal reproduction script:

repro.rs:

#[cfg(first)]
struct CycleOne(Box<CycleTwo>);

#[cfg(second)]
enum CycleOne {
    Variant(Box<CycleTwo>)
}

struct CycleTwo(CycleOne);

fn assert_send<T: Send>() {}

fn bar() {
    assert_send::<CycleOne>();
    assert_send::<CycleTwo>();
}

repro.sh:

set -euxo pipefail

rm -r foo
rustc repro.rs --crate-type lib -C incremental=foo --cfg first
rustc repro.rs --crate-type lib -C incremental=foo --cfg second

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.60.0-dev running on x86_64-unknown-linux-gnu

note: compiler flags: -C incremental --crate-type lib

query stack during panic:
#0 [evaluate_obligation] evaluating trait selection obligation `CycleTwo: core::marker::Send`
#1 [typeck] type-checking `bar`
#2 [typeck_item_bodies] type-checking all item bodies
#3 [analysis] running analysis passes on this crate
