This includes alias entries, +/// which reference previously defined external items. +/// +/// This match arm performs an `unsafe` dereference of a raw pointer +/// (`*const ComponentAlias`) in order to inspect the alias and compute +/// its section and external item kind. +/// +/// ## Invariants +/// +/// The following invariants guarantee that this operation is sound: +/// +/// 1. **The raw pointer refers to a live IR node** +/// +/// The `node` pointer stored in `ComponentItem::Alias` originates +/// from a `&ComponentAlias` reference obtained during the collect +/// phase. The encode plan does not outlive the IR that owns this +/// alias, and the assign phase executes while the IR is still alive. +/// Therefore, dereferencing `node` cannot observe freed memory. +/// +/// 2. **The IR is immutable during assignment** +/// +/// No mutable references to component IR nodes exist during the +/// assign phase. All IR structures are treated as read-only while +/// indices are being assigned. This ensures that dereferencing a +/// `*const ComponentAlias` does not violate Rust’s aliasing rules. +/// +/// 3. **The pointer has the correct provenance and type** +/// +/// The `node` pointer is never cast from an unrelated type. It is +/// created exclusively from a `&ComponentAlias` reference and stored +/// as a `*const ComponentAlias`. As a result, reinterpreting the +/// pointer as `&ComponentAlias` is well-defined. +/// +/// 4. **Alias metadata is sufficient for index assignment** +/// +/// The assign phase does not rely on alias indices being final or +/// globally unique at this point. It only uses alias metadata +/// (section and external item kind) to assign an actual index within +/// the appropriate component section. This metadata is stable and +/// independent of the eventual binary encoding order. +/// +/// ## Why this happens in the assign phase +/// +/// Alias entries may reference items defined earlier in the component, +/// and their indices depend on the final emission order. The assign +/// phase is responsible for: +/// +/// - Determining the canonical order of component items +/// - Assigning section-local indices +/// - Building the mapping from original IR indices to encoded indices +/// +/// Dereferencing the alias node here is necessary to compute the +/// correct `ExternalItemKind` for index assignment. +/// +/// ## Safety boundary +/// +/// The `unsafe` block marks the point where the encoder relies on the +/// invariants above. As long as the encode plan does not outlive the IR +/// and the IR remains immutable during assignment, this dereference is +/// sound. +/// +/// Any future change that allows IR nodes to be dropped, moved, or +/// mutably borrowed during the assign phase must re-evaluate this +/// safety argument. +/// +/// ## Summary +/// +/// - The alias pointer always refers to a live, immutable IR node +/// - The pointer has correct type provenance +/// - The assign phase only performs read-only inspection +/// +/// Therefore, dereferencing `*const ComponentAlias` during index +/// assignment is safe. pub(crate) fn assign_indices<'a>(plan: &mut ComponentPlan<'a>, indices: &mut IdxSpaces) { for item in &mut plan.items { match item { @@ -13,16 +90,16 @@ pub(crate) fn assign_indices<'a>(plan: &mut ComponentPlan<'a>, indices: &mut Idx // let ptr = *node as *const _;

The encode plan does not outlive the IR, -/// and encoding occurs while the IR is still alive. Therefore, -/// dereferencing these pointers never observes freed memory. -/// -/// 2. **Pointers are never mutated or aliased mutably** -/// -/// The IR is treated as immutable for the duration of encoding. -/// No mutable references to IR nodes exist while encoding is in -/// progress. This ensures that dereferencing a `*const T` does not -/// violate Rust’s aliasing rules. -/// -/// 3. **Pointers are only dereferenced for read-only access** -/// -/// The encoder only reads from the IR nodes in order to serialize -/// them. No mutation occurs through these raw pointers, and no -/// interior mutability is relied upon. -/// -/// 4. **All pointers refer to valid instances of `CanonicalFunction`** -/// -/// Every pointer stored in the encode plan is created from a -/// `&CanonicalFunction` reference and is never cast from an -/// unrelated type. As a result, pattern matching on the pointee’s -/// enum variants is well-defined and cannot observe invalid data. -/// -/// ## Why raw pointers are used -/// -/// Raw pointers are used instead of references to: -/// -/// - Avoid complex lifetime propagation through the encode plan -/// - Allow stable identity comparison of IR nodes -/// - Decouple the traversal (`collect`) phase from the encoding phase -/// -/// This is a common pattern in compiler and IR implementations where -/// nodes are owned by an arena or tree structure and referenced -/// indirectly during later phases. -/// -/// ## Safety boundary -/// -/// The `unsafe` block required to dereference the raw pointer marks the -/// boundary where these invariants are relied upon. As long as the -/// invariants above are maintained, matching on the pointed-to -/// `CanonicalFunction` value is safe. -/// -/// Any change that allows IR nodes to be dropped, moved, or mutably -/// aliased during encoding would invalidate these assumptions and must -/// be carefully reviewed. -/// -/// ## Summary -/// -/// - The raw pointer always refers to a live, immutable IR node -/// - The pointer is only used for identity and read-only access -/// - Enum variant matching is safe because the pointee is valid -/// -/// Therefore, dereferencing and pattern matching on -/// `*const

This module defines the infrastructure used to safely track **nested index +//! spaces** across parsing, instrumentation, and encoding phases of a +//! WebAssembly *component*. +//! +//! WebAssembly components introduce hierarchical index scopes: components may +//! contain subcomponents, instances, types, and other constructs that form +//! their own index spaces. Additionally, `(outer ...)` references allow inner +//! scopes to refer to indices defined in enclosing scopes. Correctly resolving +//! these relationships at encode time therefore requires an explicit model of +//! scope nesting rather than a single flat index map. +//! +//! At the same time, this crate supports **component instrumentation**, meaning +//! the IR may be visited, transformed, and encoded in an order that does *not* +//! correspond to the original parse order. As a result, index resolution cannot +//! rely on traversal order alone. +//! +//! To address these constraints, this module separates **identity** from +//! **ownership** using two cooperating abstractions: +//! +//! ### `ScopeRegistry` +//! +//! `ScopeRegistry` is a central, shared registry that maps *IR node identity* +//! to the index scope (`SpaceId`) that the node owns or inhabits. This mapping is +//! established during parsing and maintained throughout the lifetime of the IR. +//! +//! Key properties: +//! - Index scopes are assigned **once**, during parsing or instrumentation. +//! - Lookups are performed later, during encoding, using stable identities. +//! - Nested scopes are resolved dynamically using an explicit **scope stack** +//! rather than implicit traversal order. +//! +//! The registry intentionally operates on **raw pointers** (`*const T`) as +//! identity keys. This is safe under the invariants described below and avoids +//! coupling scope identity to Rust ownership or borrowing semantics. +//! +//! ### `ComponentHandle` +//! +//! `ComponentHandle` provides a **stable identity anchor** for a component after +//! it has been returned to the user. Once parsing completes, the `Component` +//! itself may be moved, wrapped, or otherwise owned by client code, which would +//! invalidate pointer-based identity tracking. +//! +//! `ComponentHandle` solves this by: +//! - Owning the `Component` behind an `Rc` +//! - Providing a stable allocation address for registry lookups +//! - Allowing internal encode logic to reliably recover the component’s +//! associated `SpaceId` +//! +//! All other IR nodes remain owned *within* the `Component` and therefore do +//! not require handles; their addresses remain stable for the lifetime of the +//! component. +//! +//! ### Safety and Invariants +//! +//! This design relies on the following invariants: +//! +//! - All IR nodes (except the top-level component) are owned by the `Component` +//! and are never moved after parsing. +//! - The top-level component’s identity is always accessed via +//! `ComponentHandle`, never via `&Component`. +//! - `ScopeRegistry` entries are created during parsing and may be extended +//! during instrumentation, but are never removed. +//! - Raw pointer usage is confined to **identity comparison only**; no pointer +//! is ever dereferenced. +//! +//! These constraints allow the system to use otherwise “dangerous” primitives +//! (raw pointers, shared mutation) in a controlled and domain-specific way, +//! trading generality for correctness and debuggability. +//! +//! ### Design Tradeoffs +//! +//! This approach deliberately favors: +//! - Explicit scope modeling over implicit traversal +//! - Stable identity over borrow-driven lifetimes +//! - Simplicity and traceability over highly generic abstractions +//! +//! While this introduces some indirection and bookkeeping, it keeps the encode +//! logic understandable, debuggable, and resilient to future extensions of the +//! component model. +//! +//!

Once parsing completes, the `Component` -//! itself may be moved, wrapped, or otherwise owned by client code, which would -//! invalidate pointer-based identity tracking. +//!

All other IR nodes remain owned *within* the `Component` and therefore do -//! not require handles; their addresses remain stable for the lifetime of the -//! component. +//! When an IR node needs to resolve its associated scope: +//! +//! - If the node is a component, the current `ComponentId` is used to query the +//! registry +//! - Otherwise, the node’s pointer identity is used to retrieve its `SpaceId` +//! +//! This design allows correct resolution of arbitrarily nested constructs such +//! as deeply nested components, instances, and `(outer ...)` references without +//! encoding traversal order into the registry itself. +//! +//! --- //! //! ### Safety and Invariants //! //! This design relies on the following invariants: //! -//! - All IR nodes (except the top-level component) are owned by the `Component` -//! and are never moved after parsing. -//! - The top-level component’s identity is always accessed via -//! `ComponentHandle`, never via `&Component`. +//! - Each component is assigned a unique `ComponentId` that remains stable for +//! its lifetime. +//! - All non-component IR nodes that participate in scoping are allocated in +//! stable memory (e.g. boxed and stored in append-only vectors). +//! - IR nodes are never moved or removed after registration with the +//! `ScopeRegistry`. //! - `ScopeRegistry` entries are created during parsing and may be extended //! during instrumentation, but are never removed. -//! - Raw pointer usage is confined to **identity comparison only**; no pointer +//! - Raw pointer usage is confined strictly to identity comparison; no pointer //! is ever dereferenced. //! -//! These constraints allow the system to use otherwise “dangerous” primitives -//! (raw pointers, shared mutation) in a controlled and domain-specific way, -//! trading generality for correctness and debuggability. +//! These constraints allow the system to use low-level identity mechanisms in a +//! controlled, domain-specific way while preserving correctness and debuggability. +//! +//! --- //! //! ### Design Tradeoffs //! //!

While this introduces some indirection and bookkeeping, it keeps the encode -//! logic understandable, debuggable, and resilient to future extensions of the -//! component model. +//! While this introduces some bookkeeping and indirection, it ensures that index +//! correctness is enforced structurally and remains robust in the presence of +//! instrumentation, reordering, and future extensions to the component model. //! //! In short: **index correctness is enforced structurally, not procedurally**. //! +//! ## Why `ScopeOwnerKind` Exists +//! +//! In the IR, multiple wrapper structs may reference the same underlying +//! scoped node. For example, a user-facing struct might contain a field +//! pointing to a `CoreType` that is also stored directly in a component's +//! internal vectors. Without additional tracking, the scope resolution logic +//! would see two references to the same pointer and mistakenly treat them as +//! separate scopes. +//! +//! `ScopeOwnerKind` is used to **disambiguate these cases**. Each node in the +//! scope registry records whether it is: +//! - An **original owner** of the scope (the canonical IR node), or +//! - A **derived/alias** that references an existing scope +//! +//! This ensures that the same scope is **never entered twice**, preventing +//! double-counting or incorrect index resolution during encoding. use crate::ir::component::idx_spaces::SpaceId; -// use crate::ir::component::ComponentHandle; use crate::ir::id::ComponentId; use crate::ir::types::CustomSection; use crate::{Component, Module}; @@ -102,43 +150,93 @@ use wasmparser::{ VariantCase, }; -/// A shared registry that maps IR node identity to the index scope it owns. +/// ## Scope Tracking and Index Resolution +/// +/// WebAssembly components introduce **nested index spaces**: components may +/// contain subcomponents, instances, types, and other constructs that define +/// their own indices. Inner scopes may also reference indices defined in +/// enclosing scopes via `(outer ...)`. +/// +/// Because this crate supports **instrumentation and transformation** of +/// components, the order in which the IR is visited and encoded may differ from +/// the original parse order. As a result, index resolution cannot rely on +/// traversal order alone. +/// +/// This module provides the infrastructure that ensures **correct and stable +/// index resolution** across parsing, instrumentation, and encoding. +/// +/// --- +/// +/// ### The Core Idea +/// +/// Each IR node that participates in indexing is associated with a logical +/// **scope**. These associations are recorded once and later queried during +/// encoding. +/// +/// The system guarantees that: +/// +/// - Index scopes are assigned explicitly, not inferred from traversal order +/// - Nested scopes are resolved correctly, even under reordering or +/// instrumentation +/// - Encoding always uses the correct index space for the node being emitted +/// +/// --- +/// +/// ### Component Scopes +/// +/// Components are identified by a stable **component ID** assigned when the +/// component is created or parsed. +/// +/// Component scopes are registered and resolved using this ID rather than by +/// memory identity. During traversal, encoding maintains a **stack of component +/// IDs** representing the current nesting of components. +/// +/// This makes component scope resolution: +/// +/// - Independent of ownership or storage layout +/// - Robust to reordering and nested traversal +/// - Explicit and easy to reason about +/// +/// --- +/// +/// ### Scopes Within Components +/// +/// All other scoped IR nodes—such as instances, type declarations, aliases, and +/// similar constructs—are associated with scopes relative to their enclosing +/// component. +/// +/// During encoding, a **scope stack** tracks the currently active index spaces +/// as traversal enters and exits nested constructs. When an IR node needs to +/// resolve an index, its associated scope is retrieved and interpreted relative +/// to the current stack. /// -/// `ScopeRegistry` records the `SpaceId` associated with IR nodes that introduce -/// or participate in nested index spaces (e.g. components, instances, and -/// component types). Entries are created during parsing and may be extended -/// during instrumentation, then consulted during encoding to correctly resolve -/// scoped indices such as `(outer ...)` references. +/// This allows deeply nested structures and `(outer ...)` references to be +/// encoded correctly without baking traversal assumptions into the IR. /// -/// The registry uses **raw pointer identity** (`*const T`) as lookup keys. This -/// is safe under the invariant that all registered nodes have stable addresses -/// for the lifetime of the component, and that pointers are never dereferenced— -/// only compared for identity. +/// --- /// -/// This design decouples scope resolution from traversal order, allowing IR -/// instrumentation to visit and encode nodes in arbitrary order while still -/// producing correct index mappings. +/// ### What This Enables /// -/// # Debugging tips +/// This design ensures that: /// -/// If a scope lookup fails (e.g. `scope_entry(...)` returns `None`): +/// - Instrumentation can reorder or inject IR nodes without breaking index +/// correctness +/// - Encoding logic remains simple and declarative +/// - Index resolution remains correct for arbitrarily nested components /// -/// * **Check pointer identity**: ensure the same node instance is used for both -/// registration and lookup. Lookups must use the exact allocation that was -/// registered (for example, `Rc` vs `Component` will not match). +/// Users of the library do not need to manage scopes manually—scope tracking is +/// handled transparently as part of parsing and encoding. /// -/// * **Verify registration timing**: the node must be registered *after* it is -/// fully constructed and before any encode-time lookups occur. +/// --- /// -/// * **Confirm ownership invariants**: only nodes owned by the `Component` -/// should be registered. Moving a node out of the component or cloning it -/// will invalidate pointer-based lookups. +/// ### Design Philosophy /// -/// * **Log addresses**: printing `{:p}` for the registered pointer and the -/// lookup pointer is often the fastest way to identify mismatches. +/// The scope system is intentionally explicit and conservative. Rather than +/// inferring meaning from traversal order, it records the structure of index +/// spaces directly and resolves them mechanically at encode time. /// -/// These failures usually indicate a violation of the registry’s ownership or -/// lifetime assumptions rather than a logic error in index assignment itself. +/// In short: **index correctness is enforced structurally, not procedurally**. +/// ``` #[derive(Default, Debug)] pub(crate) struct IndexScopeRegistry { pub(crate) node_scopes: HashMap, ScopeEntry>, @@ -214,11 +312,6 @@ impl GetScopeKind for Component<'_> { ScopeOwnerKind::Component } } -// impl GetScopeKind for ComponentHandle<'_> { -// fn scope_kind(&self) -> ScopeOwnerKind { -// ScopeOwnerKind::Component -// } -// } impl GetScopeKind for CoreType<'_> { fn scope_kind(&self) -> ScopeOwnerKind { match self { @@ -315,7 +408,6 @@ pub struct ComponentStore<'a> { impl<'a> ComponentStore<'a> { pub fn get(&self, id: &ComponentId) -> &'a Component<'a> { self.components.get(id).unwrap() - // unsafe { ptr.cast::>().as_ref() } } } diff --git a/src/ir/component/section.rs b/src/ir/component/section.rs index 31cd6a96..a603d9cd 100644 --- a/src/ir/component/section.rs +++ b/src/ir/component/section.rs @@ -93,7 +93,6 @@ pub(crate) fn populate_space_for_comp_ty( let section = ComponentSection::ComponentType;

"actual id") of each component item based on the order in which -/// items will be emitted into the binary. This includes alias entries, -/// which reference previously defined external items. -/// -/// This match arm performs an `unsafe` dereference of a raw pointer -/// (`*const ComponentAlias`) in order to inspect the alias and compute -/// its section and external item kind. -/// -/// ### Invariants -/// -/// The following invariants guarantee that this operation is sound: -/// -/// 1. **The raw pointer refers to a live IR node** -/// -/// The `node` pointer stored in `ComponentItem::Alias` originates -/// from a `&ComponentAlias` reference obtained during the collect -/// phase. The encode plan does not outlive the IR that owns this -/// alias, and the assign phase executes while the IR is still alive. -/// Therefore, dereferencing `node` cannot observe freed memory. -/// -/// 2. **The IR is immutable during assignment** -/// -/// No mutable references to component IR nodes exist during the -/// assign phase. All IR structures are treated as read-only while -/// indices are being assigned. This ensures that dereferencing a -/// `*const ComponentAlias` does not violate Rust’s aliasing rules. -/// -/// 3. **The pointer has the correct provenance and type** -/// -/// The `node` pointer is never cast from an unrelated type. It is -/// created exclusively from a `&ComponentAlias` reference and stored -/// as a `*const ComponentAlias`. As a result, reinterpreting the -/// pointer as `&ComponentAlias` is well-defined. -/// -/// 4. **Alias metadata is sufficient for index assignment** -/// -/// The assign phase does not rely on alias indices being final or -/// globally unique at this point. It only uses alias metadata -/// (section and external item kind) to assign an actual index within -/// the appropriate component section. This metadata is stable and -/// independent of the eventual binary encoding order. -/// -/// ### Why this happens in the assign phase -/// -/// Alias entries may reference items defined earlier in the component, -/// and their indices depend on the final emission order. The assign -/// phase is responsible for: -/// -/// - Determining the canonical order of component items -/// - Assigning section-local indices -/// - Building the mapping from original IR indices to encoded indices -/// -/// Dereferencing the alias node here is necessary to compute the -/// correct `ExternalItemKind` for index assignment. -/// -/// ### Safety boundary -/// -/// The `unsafe` block marks the point where the encoder relies on the -/// invariants above. As long as the encode plan does not outlive the IR -/// and the IR remains immutable during assignment, this dereference is -/// sound. -/// -/// Any future change that allows IR nodes to be dropped, moved, or -/// mutably borrowed during the assign phase must re-evaluate this -/// safety argument. -/// -/// ### Summary -/// -/// - The alias pointer always refers to a live, immutable IR node -/// - The pointer has correct type provenance -/// - The assign phase only performs read-only inspection -/// -/// Therefore, dereferencing `*const ComponentAlias` during index -/// assignment is safe. -pub(crate) fn assign_indices(plan: &mut ComponentPlan, ctx: &mut VisitCtx) { - for item in &mut plan.items { - match item { - ComponentItem::Component { - node, - plan: subplan, - idx, - } => unsafe { - let ptr: &Component = &**node;
