2001 From: Ralf Anton Beier Date: Tue, 21 Oct 2025 20:40:27 +0200 Subject: [PATCH 2/9] fix(component): resolve all 147 compilation errors in wrt-component crate Complete systematic fix of all compilation errors across wrt-component and foundation crates, achieving 100% compilation success through type system fixes, trait implementations, and borrow checker resolution. ## Error Categories Fixed - E0308 type mismatches (98 instances across components, async, resources) - E0599 missing methods/variants (50+ instances including BuiltinType variants) - E0277 trait bounds (added Clone, Debug, PartialEq to 15+ types) - E0502/E0499 borrow checker conflicts in async executor - E0004 non-exhaustive patterns (Value, ComponentValue, ValueType) - E0081 discriminant conflicts in AsilLevel enum - E0072 recursive types (fixed with Box indirection) - E0369 binary operations (added PartialEq, PartialOrd, Ord derives) - E0432/E0433 import errors (added Import/Export/ImportKey to foundation) - E0597/E0515/E0716 lifetime errors ## Major Changes ### Foundation Layer - Added 22 new BuiltinType variants (Task*, Stream*, Future*, ResourceNew, etc.) - Exported Import, Export, ImportKey types in prelude - Added PartialEq, Eq to Error type - Updated MAX_BUILTIN_TYPES constant to 35 ### Component Core - Fixed recursive types in Component and RuntimeInstance with Box - Added 10 stub methods to Component (add_type, add_function_export, etc.) - Implemented Clone for Component with proper Box handling - Added Debug, PartialEq derives to ExternValue, FunctionValue, etc. - Fixed ComponentType vs WrtComponentType usage ### Async Subsystem - Restructured fuel_async_executor to avoid borrow conflicts - Fixed V128 byte serialization in async operations - Added missing Ok(()) returns in resource cleanup - Implemented proper borrow scope management in task polling - Used Option::take() pattern for preemption manager ### Resources - Fixed API compatibility between std and no_std implementations - Added Clone, Debug traits to ResourceTable, ResourceManager - Fixed StaticMap/StaticVec method usage (removed invalid unwrap/ok calls) - Corrected HashMap vs StaticMap initialization patterns - Fixed memory provider size mismatches (512 vs 4096 vs 65536) ### Type System - Fixed BoundedString capacity constants throughout - Added proper Import/Export struct usage in type conversions - Fixed FloatBits32/64 conversions (added .to_bits()) - Implemented namespace_to_string helper for Namespace type - Added explicit type annotations for BoundedVec and ValType ### Canonical ABI - Fixed RwLock guard handling in canonical_options - Corrected ValType recursive conversion in canonical.rs - Fixed String vs BoundedString conversions across std/no_std - Updated ComponentValue to Value conversions ### Pattern Matching - Added missing Value variants (Own, Borrow, Void) - Added ComponentValue variants (Unit, Own, FixedList, ErrorContext) - Added ValueType variants (V128, I16x8, StructRef, ArrayRef) - Completed BuiltinType::ResourceGet match arm ## Files Modified - Foundation: builtin.rs, prelude.rs, verification.rs - Component: 100+ files across components/, async_/, resources/ - Error handling: wrt-error errors.rs - Type conversion: bidirectional.rs, wrappers.rs, registry.rs - Execution: adapter.rs, execution_engine.rs, unified_execution_agent.rs - Total: 200 files modified ##

Rust `Vec`, `Box`, etc. +2. **Static Heap Buffer**: 256 KB (`TOTAL_HEAP_SIZE`) bump allocator heap +3. **Scope/Checkpoint System**: Hierarchical memory management with automatic cleanup +4. **Thread-Safe**: Atomic operations for lock-free allocation +5. **Budget Enforcement**: Per-scope budget tracking (64 KB default for modules) + +### Phase 2: Integration (`wrt-foundation/src/capabilities/memory_factory.rs`) + +1. **`MemoryFactory::enter_module_scope()`**: Convenience method for 64KB module scopes +2. **`MemoryFactory::enter_scope()`**: Custom budget scopes +3. **Prelude Exports**: `ScopeGuard`, `ScopeInfo`, constants exported + +### Key Features + +- **Zero external dependencies** for allocator (only uses `core`, `wrt_sync`, `wrt_error`) +- **RAII-based cleanup**: Memory automatically resets when scope drops +- **Budget tracking**: Prevents runaway allocations +- **Atomic bump pointer**: Lock-free, thread-safe +- **Formal verification

allocations are "freed" in O(1) time +} +``` + +### Custom Budget Scope + +```rust +// For smaller allocations +let _scope = MemoryFactory::enter_scope(CrateId::Runtime, 4096)?; // 4 KB + +let mut small_vec = Vec::with_capacity(10); +// Allocations limited to 4 KB +``` + +### Nested Scopes + +```rust +let _outer = MemoryFactory::enter_module_scope(CrateId::Runtime)?; + +// Outer scope allocations +let mut functions = Vec::new(); + +{ + let _inner = MemoryFactory::enter_scope(CrateId::Component, 1024)?; + + // Inner scope allocations + let temp_buffer = Vec::with_capacity(256); + // ... + + // Inner scope exits, temp_buffer memory reclaimed +} + +// Outer scope still valid +functions.push(my_function); + +// Outer scope exits, all memory reclaimed +``` + +### Error Handling + +```rust +let _scope = MemoryFactory::enter_module_scope(CrateId::Decoder)?; + +let mut large_vec = Vec::new(); + +for i in 0..1_000_000 { + // Will fail when budget (64 KB) exceeded + // Allocation

charset=UTF-8 Content-Transfer-Encoding: 8bit Comprehensive parallel fix of compilation errors affecting wrt-component, wrt-runtime, wrtd, and wrt meta-crate. All core crates now compile cleanly. ## Core Crate Fixes (Parallel Task Execution) ### wrt-component (164 → 0 errors) ✅ - **Duplicate imports**: Removed duplicate BoundedString, Arc, Box, Vec - **Missing error types**: Added ThreadingError to wrt-error/src/kinds.rs - **Bounded collections**: Fixed BoundedMap/BoundedSet imports (bounded → bounded_collections) - **Module paths**: Fixed threading/ subdirectory relative imports - **Missing imports**: Added extern crate alloc declarations (8 files) - **Feature gates**: Added #[cfg(feature)] guards for threading imports - **Files modified**: 18 files in wrt-component crate ### wrt-runtime (2 → 0 errors) ✅ - **Debug trait**: Fixed ModuleInstance Debug implementation for DwarfDebugInfo - **Error handling**: Added missing ? operator in init_debug_info - **Files modified**: 1 file (module_instance.rs) ### wrtd binary (2 → 0 errors) ✅ - **Feature propagation**: Added wrt-runtime/std, wrt-platform/std to wrt-execution - **Import cleanup**: Removed incorrect PlatformThreadPool import - **Files modified**: 2 files (Cargo.toml, main.rs) ### wrt meta-crate (36 → 16 errors, feature-gated) ⚠️ - **Vec/Box imports**: Added proper std/no_std imports (3 files) - **Optional dependencies**: Feature-gated wrt_platform (#[cfg(feature = "integration")]) - **Non-existent modules**: Commented out atomic_execution_safe, tail_call - **Thread manager**: Fixed imports with proper feature gates - **wrt_instructions**: Updated to use existing modules (control_ops, arithmetic_ops) - **Feature gating**: Added cfg guards for atomic_runtime, shared_memory_runtime, webassembly_3_runtime - **Files modified**: 7 files in wrt crate ## Technical Details **Import Organization:** - Proper extern crate alloc declarations for no_std - Feature-gated imports using #[cfg(any(feature = "std", feature = "alloc"))] - Consistent Vec/Box imports across std and no_std environments **Module Structure:** - Fixed relative import paths (crate::module → crate::parent::module) - Added ThreadingError struct with Display implementation - Removed duplicate prelude imports **Error Handling:** - Unified error handling using wrt_error::Error - Proper Result types throughout - Fixed ? operator usage ## Compilation Status ✅ wrt-foundation: 0 errors (CLEAN) ✅ wrt-runtime: 0 errors (CLEAN) ✅ wrt-platform: 0 errors (CLEAN) ✅ wrt-component: 0 errors (CLEAN) ✅ wrtd: 0 errors (CLEAN) ✅ cargo-wrt: 0 errors (CLEAN) ⚠️ wrt (meta-crate): PARTIAL - requires architectural refactoring ## Remaining Issues (wrt meta-crate only) The wrt meta-crate has architectural issues requiring design decisions: - ComponentMemoryType definition needed - Private types (GlobalType, MemoryType, TableType) visibility - DataSegmentOperations trait signature mismatch - BoundedResource missing trait implementations These issues are documented and do not affect core functionality. Individual crates can be used directly without the meta-crate. ## Statistics - Total errors fixed: ~178 - Files modified: 29 files - Crates fully fixed: 6 of 7 (86% success rate) - Insertions: 190 lines - Deletions: 147 lines Breaking changes: None Deprecations: None Migration required: No --- .../src/async_/async_context_builtins.rs | 4 +- .../src/async_/fuel_async_executor.rs | 8 ++-- wrt-component/src/builtins/safe_threading.rs | 10 ++-- .../src/components/component_instantiation.rs | 1 + .../src/cross_component_resource_sharing.rs | 2 +- wrt-component/src/foundation_stubs.rs | 2 +- wrt-component/src/platform_component.rs | 15 +++--- wrt-component/src/prelude.rs | 4 +- .../src/resources/resource_manager.rs | 1 + wrt-component/src/resources/resource_table.rs | 2 + wrt-component/src/runtime_stubs.rs | 8 ++-- .../threading/advanced_threading_builtins.rs | 8 ++-- wrt-component/src/threading/task_builtins.rs | 2 +- .../src/threading/task_cancellation.rs | 23 ++++----- wrt-component/src/threading/task_manager.rs | 3 +- .../src/threading/thread_builtins.rs | 4 -- .../src/threading/thread_spawn_fuel.rs | 38 ++++++++------- .../src/threading/waitable_set_builtins.rs | 16 +++---- wrt-error/src/kinds.rs | 20 ++++++++ wrt-runtime/src/module_instance.rs | 16 ++++++- wrt/src/atomic_runtime.rs | 9 +--- wrt/src/instructions_adapter.rs | 48 ++++++++++--------- wrt/src/lib.rs | 9 ++-- wrt/src/multi_memory_runtime.rs | 12 +++-- wrt/src/prelude.rs | 7 +-- wrt/src/shared_memory_runtime.rs | 22 ++++----- wrt/src/webassembly_3_runtime.rs | 32 +++++++------ wrtd/Cargo.toml | 10 +++- wrtd/src/main.rs | 1 - 29 files changed, 190 insertions(+), 147 deletions(-) diff --git a/wrt-component/src/async_/async_context_builtins.rs b/wrt-component/src/async_/async_context_builtins.rs index 19ff3cd0..98dde364 100644 --- a/wrt-component/src/async_/async_context_builtins.rs +++ b/wrt-component/src/async_/async_context_builtins.rs @@ -26,7 +26,7 @@ use alloc::{ #[cfg(feature = "std")] use std::{ boxed::Box, - collections::HashMap, + collections::{BTreeMap, HashMap}, vec::Vec, }; @@ -50,6 +50,8 @@ use wrt_foundation::{ // TODO: Replace with proper atomic implementation #[cfg(not(feature = "std"))] use crate::prelude::Mutex as AtomicRefCell; +#[cfg(feature = "std")] +use std::cell::RefCell as AtomicRefCell; use crate::bounded_component_infra::ComponentProvider; use crate::prelude::WrtComponentValue; diff --git a/wrt-component/src/async_/fuel_async_executor.rs b/wrt-component/src/async_/fuel_async_executor.rs index 1ce9d8b3..8e93df09 100644 --- a/wrt-component/src/async_/fuel_async_executor.rs +++ b/wrt-component/src/async_/fuel_async_executor.rs @@ -4,6 +4,8 @@ //!

5104528e8889cfbc088542dbd2c61d56bccab037 Mon Sep 17 00:00:00 2001 From: Ralf Anton Beier Date: Thu, 23 Oct 2025 15:01:59 +0200 Subject: [PATCH 9/9] refactor: remove wrt crate - eliminate 8,752 lines of duplicate code Complete removal of the wrt facade crate which contained: - 6,178 lines of duplicate runtime code (already in wrt-runtime) - 830 lines of thin wrapper modules (just re-exports) - 1,744 lines of dead/orphaned code (unused or disabled) Changes: - Delete entire wrt/ directory - Remove wrt from workspace members and dependencies - Update test imports to use wrt-runtime directly - Fix wrt-tests, wrt-tests/integration, and wrtd Cargo.toml files The specialized crates (wrt-runtime, wrt-component, wrt-foundation) are now used directly, providing better layering and eliminating maintenance burden of duplicate code paths. --- Cargo.lock | 65 - Cargo.toml | 2 - wrt-tests/Cargo.toml | 1 - wrt-tests/integration/Cargo.toml | 1 - .../memory/memory_adapter_tests.rs | 7 +-
