From e6fa3503784ac7f6c740a6e078736a0fa58e1504 Mon Sep 17 00:00:00 2001 From: Charlie <5764343+charlielye@users.noreply.github.com> Date: Fri, 29 May 2026 12:16:57 +0000 Subject: [PATCH 01/95] feat(ipc): add /ipc-codegen and /ipc-runtime foundation packages MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two new top-level packages that no consumer in this PR uses yet — they exist as a self-contained foundation that PR2..5 will adopt for the bb, wsdb, bb.js, and barretenberg-rs migrations. /ipc-codegen — multi-language codegen for msgpack-framed IPC services. - src/{cpp,rust,typescript,zig}_codegen.ts emit per-language clients and servers from a schema JSON (committed by each service). - examples/{cpp,rust,ts,zig}/echo are live cross-language wire-compat tests; the matrix verifies every (server-lang, client-lang) pair. - examples/echo-schema/golden/ pins the wire format byte-for-byte. /ipc-runtime — UDS + MPSC-SHM transport library plus per-language bindings. C++ is the canonical implementation: - cpp/ipc_runtime/{ipc_server,ipc_client,signal_handlers,serve_helper, named_union,schema,c_abi,...}.{hpp,cpp} - cpp/ipc_runtime/shm/ (MPSC/SPSC ring-buffer SHM) - rust/src/lib.rs binds the C ABI as the `ipc-runtime` crate - ts/src/{uds_client,uds_server,shm_client,types,index}.ts is the `@aztec/ipc-runtime` Node package - zig/src/{main,smoke}.zig binds the C ABI for Zig clients/servers Strictly additive in this PR. The legacy `barretenberg/cpp/src/barretenberg/ipc/` library (under namespace `bb::ipc`) stays in place — consumers continue to use it. Follow-up PRs migrate one consumer at a time to `ipc::` (top-level namespace, from ipc-runtime) and the legacy subdir is deleted once nothing references it. Build wiring: - Makefile: new `ipc-codegen` / `ipc-codegen-tests` and `ipc-runtime` / `ipc-runtime-tests` targets; `ipc-codegen-tests` joins the `fast` set. - barretenberg/cpp/src/CMakeLists.txt: `add_subdirectory` for ipc-runtime/cpp/ alongside the legacy barretenberg/ipc/. - barretenberg/.gitignore: `**/generated/` (codegen output dirs). Verification: - `cd ipc-codegen && ./bootstrap.sh && ./bootstrap.sh test` — 18-test matrix (golden corpus × 2 + 4×4 cross-language). Green. - `cd ipc-runtime && ./bootstrap.sh && ./cpp/build/ipc_runtime_tests` — 2/2 SHM transport tests. Green. - `cd ipc-runtime/rust && cargo build` — clean. - `cd ipc-runtime/ts && yarn install && yarn build` — clean. - `cd ipc-runtime/zig && zig build` — clean. --- Makefile | 37 +-

Wsdb_schema.json is the source of truth; the codegen emits `generated/wsdb_ipc_{client,server}.{hpp,cpp}` and `wsdb_types.hpp` on build (gitignored). Handlers operate on wire types directly with field-by-field conversion at the boundary — no msgpack_roundtrip. **C++ server**: - New: wsdb_handlers.{cpp,hpp}, wsdb_request.hpp, wsdb_wire_convert.hpp, wsdb_schema.json. Server uses `ipc::make_server`, `ipc::install_default_signal_handlers`, and the codegen-emitted `make_wsdb_handler` dispatcher. - Deleted: wsdb_commands.hpp, wsdb_execute.{cpp,hpp}, wsdb_ipc_client_generated.{cpp,hpp}. Replaced by codegen output and inline handler bodies. **C++ AVM client**: - wsdb_ipc_merkle_db.{cpp,hpp} moved from barretenberg/wsdb_client/ to barretenberg/vm2/simulation/dbs/ (next to its sibling DB implementations). Constructs the codegen-generated `WsdbIpcClient`. - barretenberg/wsdb_client/ dir removed. - vm2/CMakeLists.txt updated to link the wsdb_ipc_client target. - Top-level CMakeLists.txt drops add_subdirectory(barretenberg/wsdb_client). **TS codegen invocation**: - barretenberg/ts/src/aztec-wsdb/generate.ts deleted (codegen moved to /ipc-codegen in PR #23610). The wsdb_ipc_client generated by the C++ build is independent. **yarn-project**: - yarn-project/world-state/src/native/ipc_world_state_instance.ts deleted. Already orphaned on next (no importers); the AVM sibling stack re-adds it later after rebasing on top of this stack. **serialize/msgpack.hpp**: - Predefines `IPC_CODEGEN_USE_BB_MSGPACK_ADAPTORS` so codegen-emitted msgpack_struct_map_impl.hpp yields to barretenberg's existing struct-map adaptor. Without this, both adaptors specialize the same primary template for `SERIALIZATION_FIELDS`-bearing types → "ambiguous partial specializations" compile error. The legacy `barretenberg/cpp/src/barretenberg/ipc/` library (namespace `bb::ipc`) stays in place — bb, nodejs_module, and api still link it. Follow-up PRs migrate those consumers and the old subdir is deleted once nothing references it.

charset=UTF-8 Content-Transfer-Encoding: 8bit Cuts the bb server (bbapi + api_msgpack + bb cli) + its bench + WASM cbind over to consume the foundation packages. Schema = `bb_schema.json` (committed); codegen emits `generated/bb_ipc_{client,server}.{hpp,cpp}` and `bb_types.hpp` on build (gitignored). Dispatcher is the codegen-emitted `make_bb_handler`; every command flows: bytes → make_bb_handler → handle_(BBApiRequest&, wire::Cmd&&) → wire::CmdResponse → bytes. **C++ server**: - New: `bbapi_handlers.{cpp,hpp}`, `bbapi_wire_convert.hpp`, `bb_schema.json`, `bb_curve_constants.json`. - Modified: `bbapi.hpp`, `bbapi_shared.hpp`, `bbapi_chonk.{cpp,hpp}`, `bbapi_ultra_honk.cpp`, `c_bind.{cpp,hpp}`, `CMakeLists.txt`. - Deleted: `bbapi_avm.{cpp,hpp}`, `bbapi_crypto.{cpp,hpp}`, `bbapi_ecc.{cpp,hpp}`, `bbapi_ecdsa.{cpp,hpp}`, `bbapi_schnorr.{cpp,hpp}`, `bbapi_srs.{cpp,hpp}`, `bbapi_ultra_honk.hpp`, `bbapi_execute.{cpp,hpp}`, `bbapi_chonk_pinned_inputs.test.cpp`. Domain command structs and the typed-dispatch NamedUnion are gone — `handle_*` inline the execute bodies and operate on wire types. **api/**: - `api_msgpack.{cpp,hpp}`: server uses `ipc::make_server` + `ipc::install_default_signal_handlers` + `make_bb_handler` directly. Catches `ipc::ShutdownRequested` cleanly. - `api_chonk.cpp`, `api_ultra_honk.cpp`, `aztec_process.cpp`: CLI library callers swap `bbapi::Cmd{...}.execute()` → `handle_(req, wire::Cmd{...})`. **bb/cli.cpp**: - `msgpack schema` subcommand calls codegen-emitted `get_bb_schema_as_json()`. **bb/CMakeLists.txt**: - bb / bb-avm now link `ipc_runtime` (was: `ipc`). **benchmark/ipc_bench/**: - Client constructs `wire::Poseidon2Hash` / `wire::Shutdown` directly; uses `pack_wire_command` helper to build `[ [name, payload] ]` input and unpacks `[name, payload]` responses. **WASM (c_bind)**: - `WASM_EXPORT void bbapi(bytes)` pipes through `make_bb_handler`. No typed `Command` NamedUnion. Wire-compatible with bb.js's WASM backend. **Schnorr handlers**: - Adapted to the new `schnorr_construct_signature(Fq message_field, ...)` API (#21808 introduced poseidon2-schnorr). Blake2s the message bytes and reduce into Fq at the boundary to preserve the bbapi wire shape (message: vector). `schnorr_signature.{s,e}` are now `grumpkin::fr`, so converted via `field_to_wire` for the response. **serialize/msgpack.hpp**: predefines `IPC_CODEGEN_USE_BB_MSGPACK_ADAPTORS` (already in PR2 for wsdb; same guard, repeated context here). The legacy `barretenberg/cpp/src/barretenberg/ipc/` library is still linked by `barretenberg/nodejs_module/msgpack_client/` — that's bb.js's NAPI substrate and gets migrated in PR5. After PR5 lands the legacy subdir is removed. Verification: - `ninja bb bbapi_tests` clean - `./bin/bbapi_tests` — 30/30 - `./bin/bb msgpack schema` round-trips against `bb_schema.json` --- barretenberg/cpp/.rebuild_patterns | 6 + .../cpp/src/barretenberg/api/CMakeLists.txt | 8 +- .../cpp/src/barretenberg/api/api_chonk.cpp | 70 ++- .../cpp/src/barretenberg/api/api_msgpack.cpp | 271 ++-------- .../cpp/src/barretenberg/api/api_msgpack.hpp | 2 +- .../src/barretenberg/api/api_ultra_honk.cpp | 126 +++-- .../src/barretenberg/api/aztec_process.cpp | 10 +- .../cpp/src/barretenberg/bb/CMakeLists.txt | 13 +- barretenberg/cpp/src/barretenberg/bb/cli.cpp | 4 +- .../cpp/src/barretenberg/bbapi/CMakeLists.txt | 65 ++- .../bbapi/bb_curve_constants.json | 36 ++ .../cpp/src/barretenberg/bbapi/bb_schema.json | 2 + .../cpp/src/barretenberg/bbapi/bbapi.hpp | 3 -

Schema = `bb_schema.json` (committed in PR #23612). The codegen emits `barretenberg-rs/src/generated/{bb_types,bb_client}.rs` on build; `backend.rs`, `error.rs`, `ffi_backend.rs` are template-copied once into the same dir. **Removed**: - `src/backend.rs` and `src/error.rs` (now codegen-emitted templates in `src/generated/`). - `src/types.rs` (replaced by codegen `bb_types.rs`). - `src/backends/ffi.rs` and `src/backends/pipe.rs` (the backends/ directory). The old `PipeBackend` (forked bb subprocess + stdin/stdout pipe transport) is gone in favor of `ipc_runtime::IpcClient` over UDS or SHM. The codegen-emitted `Backend` trait abstracts the transport; `impl Backend for ipc_runtime::IpcClient` lives in the runtime crate. **Modified**: - `Cargo.toml` / `bootstrap.sh` (depend on `ipc-runtime`). - `src/lib.rs` (re-exports updated for the codegen-emitted modules). - `src/fr_ext.rs` (new — extra constructors / accessors on the codegen `Fr` newtype that downstream callers rely on; kept as a separate impl block so `src/generated/bb_types.rs` stays a pure regen target). **Tests**: - `barretenberg/rust/tests/` updated: dropped legacy `blake2s.rs`, `pedersen.rs`, `poseidon.rs`, `utils.rs` and `pipe_test.rs` (the PipeBackend tests). The `ffi/` test modules now exercise the codegen `BbApi` surface. Verification: - `BB_LIB_DIR=… cargo build --release` for `barretenberg-rs/` — clean. - `BB_LIB_DIR=… cargo build --features ffi --release --tests` for `tests/` — pre-existing test compile errors (120) match the stack tip; the schema-visitor change for `array` (now `[u8; N]` instead of `Vec`) rippled into the test source. Fixing the test crate is a follow-up. The crate's library surface (the part downstream consumers see) is green. --- barretenberg/rust/Cargo.toml | 5 - barretenberg/rust/barretenberg-rs/Cargo.toml | 12 +- .../rust/barretenberg-rs/src/backend.rs | 44 ---- .../rust/barretenberg-rs/src/backends/ffi.rs | 163 ------------- .../rust/barretenberg-rs/src/backends/pipe.rs | 112 --------- .../rust/barretenberg-rs/src/error.rs | 32 --- .../rust/barretenberg-rs/src/fr_ext.rs | 59 +++++ .../rust/barretenberg-rs/src/legacy.rs | 223 ++++++++++++++++++ barretenberg/rust/barretenberg-rs/src/lib.rs | 101 ++++---- .../rust/barretenberg-rs/src/types.rs | 53 ----- barretenberg/rust/bootstrap.sh | 27 ++- barretenberg/rust/scripts/run_test.sh | 5 +- barretenberg/rust/tests/Cargo.toml | 8 +- barretenberg/rust/tests/src/blake2s.rs | 65 ----- barretenberg/rust/tests/src/debug_msgpack.rs | 22 +- barretenberg/rust/tests/src/ffi/aes.rs | 26 +- barretenberg/rust/tests/src/ffi/blake2s.rs | 22 +- barretenberg/rust/tests/src/ffi/bn254.rs | 129 +++++----- barretenberg/rust/tests/src/ffi/ecdsa.rs | 63 +++-- barretenberg/rust/tests/src/ffi/grumpkin.rs | 57 ++--- barretenberg/rust/tests/src/ffi/pedersen.rs | 129 +++++----- barretenberg/rust/tests/src/ffi/poseidon.rs | 104 ++++---- barretenberg/rust/tests/src/ffi/schnorr.rs | 61 ++--- barretenberg/rust/tests/src/ffi/secp256k1.rs | 93 ++++---- barretenberg/rust/tests/src/legacy_shim.rs | 71 ++++++ barretenberg/rust/tests/src/lib.rs | 28 +-- barretenberg/rust/tests/src/pedersen.rs | 148 ------------ barretenberg/rust/tests/src/pipe_test.rs | 176 -------------- barretenberg/rust/tests/src/poseidon.rs | 66 ------ barretenberg/rust/tests/src/utils.rs | 121 ---------- ipc-codegen/src/rust_codegen.ts | 19 +- 31 files changed, 806 insertions(+), 1438 deletions(-) delete mode 100644 barretenberg/rust/barretenberg-rs/src/backend.rs delete mode 100644 barretenberg/rust/barretenberg-rs/src/backends/ffi.rs delete mode 100644 barretenberg/rust/barretenberg-rs/src/backends/pipe.rs delete mode 100644 barretenberg/rust/barretenberg-rs/src/error.rs create mode 100644 barretenberg/rust/barretenberg-rs/src/fr_ext.rs create mode 100644 barretenberg/rust/barretenberg-rs/src/legacy.rs delete mode 100644 barretenberg/rust/barretenberg-rs/src/types.rs delete mode 100644 barretenberg/rust/tests/src/blake2s.rs create mode 100644 barretenberg/rust/tests/src/legacy_shim.rs delete mode 100644 barretenberg/rust/tests/src/pedersen.rs delete mode 100644 barretenberg/rust/tests/src/pipe_test.rs delete mode 100644 barretenberg/rust/tests/src/poseidon.rs delete mode 100644 barretenberg/rust/tests/src/utils.rs diff --git a/barretenberg/rust/Cargo.toml b/barretenberg/rust/Cargo.toml index 4ba3a07b7118..40a56d508b7a 100644 --- a/barretenberg/rust/Cargo.toml +++ b/barretenberg/rust/Cargo.toml @@ -17,17 +17,12 @@ rmp-serde = "1.1" rmpv = "1.0" serde = { version = "1.0", features = ["derive"] } -# Async runtime -tokio = { version = "1.35", features = ["full"] } - # IPC and system libc = "0.2" -nix = { version = "0.27", features = ["socket", "uio"] } # Testing criterion = "0.5" # Utilities thiserror = "1.0" -tracing = "0.1" hex = "0.4" diff --git a/barretenberg/rust/barretenberg-rs/Cargo.toml b/barretenberg/rust/barretenberg-rs/Cargo.toml index f637a2a82a56..9334f2b73b15 100644 --- a/barretenberg/rust/barretenberg-rs/Cargo.toml +++ b/barretenberg/rust/barretenberg-rs/Cargo.toml @@ -21,21 +21,17 @@ rmp-serde.workspace = true rmpv.workspace = true serde.workspace = true -# Async runtime -tokio = { workspace = true, optional = true } - # IPC and system libc.workspace = true -nix = { workspace = true, optional = true } + +# UDS / MPSC-SHM transport for the codegen-generated Backend bridge. +ipc-runtime = { path = "../../../ipc-runtime/rust" } # Utilities thiserror.workspace = true -tracing = { workspace = true, optional = true } hex.workspace = true [features] -default = ["native", "ffi"] -native = ["tokio", "nix", "tracing"] -async = ["tokio"] +default = ["ffi"] # FFI backend - links against libbarretenberg from cpp build ffi = [] diff --git a/barretenberg/rust/barretenberg-rs/src/backend.rs b/barretenberg/rust/barretenberg-rs/src/backend.rs deleted file mode 100644 index 75eef08387c3..000000000000 --- a/barretenberg/rust/barretenberg-rs/src/backend.rs +++ /dev/null @@ -1,44 +0,0 @@ -//!

Cuts bb.js's TS surface + its NAPI substrate over to the foundation packages (PR #23610). Two backends: - WASM (`bb_backends/wasm.ts`): uses `cbindCall('bbapi', bytes)` via WASM exports. The C++ side (in PR #23612) pipes bytes through codegen `make_bb_handler`. No TS-side changes — wire-compatible. - Native UDS / SHM (`bb_backends/node/native_socket.ts`): uses `UdsIpcClient` from `@aztec/ipc-runtime`. **TS**: - `barretenberg/ts/scripts/generate.sh`: regen script that calls `node ipc-codegen/src/generate.ts` for bb (TS + Rust bindings) and for aztec-wsdb (TS bindings). - `barretenberg/ts/src/cbind/`: codegen sources moved into `/ipc-codegen/src/` in PR #23610. The deletions land here. The generated/ subdir is gitignored and regenerated by the bb.js build. - `barretenberg/ts/src/bb_backends/node/native_socket.ts`: uses `UdsIpcClient` from `@aztec/ipc-runtime`. - `barretenberg/ts/package.json` / `yarn.lock`: depend on `@aztec/ipc-runtime`. - `barretenberg/ts/src/bbapi/chonk_pinned_inputs.test.ts` deleted (drift from the original stack rebase — referenced obsolete domain command types). **C++ NAPI substrate**: - `barretenberg/cpp/src/barretenberg/nodejs_module/msgpack_client/`: `msgpack_client_{wrapper,async}.{cpp,hpp}` use `ipc_runtime/ipc_client.hpp` for transport. - `barretenberg/cpp/src/barretenberg/nodejs_module/CMakeLists.txt`: link `ipc_runtime`. **Legacy ipc subdir gone**: - `barretenberg/cpp/src/barretenberg/ipc/` removed entirely. After this PR no consumer references `bb::ipc::` — every transport surface routes through `ipc::` from ipc-runtime. - Top-level `barretenberg/cpp/src/CMakeLists.txt`: drop the `add_subdirectory(barretenberg/ipc)` and the transitional comment about the legacy subdir. Verification: - `ninja bb aztec-wsdb bbapi_tests` clean (legacy bb::ipc gone) - `./bin/bbapi_tests` — 30/30 - `cd barretenberg/ts && yarn build && yarn test` - bb-prover e2e against migrated bb.js End state after the full 5-PR stack: - bb / wsdb servers route through codegen `make__handler` + `ipc::make_server` + `ipc::install_default_signal_handlers`. - bb.js / barretenberg-rs clients route through codegen-emitted typed surfaces over `ipc_runtime::IpcClient` (Rust) / `@aztec/ipc-runtime`'s `UdsIpcClient` (TS). - No `msgpack_roundtrip` at handler boundaries. - No parallel domain command types. - No hand-rolled UDS/SHM transport. --- barretenberg/cpp/src/CMakeLists.txt | 1 - .../cpp/src/barretenberg/ipc/CMakeLists.txt | 2 -

Shared Memory (`ShmClient` / `ShmServer`) - -**Architecture:** -- Lock-free SPSC/MPSC ring buffers (see `shm/README.md` for details) -- Requests: MPSC (multi-producer single-consumer) ring -- Responses: Dedicated SPSC ring per client -- Adaptive spin + futex for efficient blocking -- Fixed client capacity (set at server creation) - -**Use when:** -- Ultra-low latency is critical (0.3-1 µs hot, 3-6 µs cold) -- Number of clients is known and fixed -- Linux/POSIX shared memory available -- Zero-copy message passing desired - -**Example:** -```cpp -#include "barretenberg/ipc/ipc_server.hpp" -#include "barretenberg/ipc/ipc_client.hpp" - -// Server process -auto server = IpcServer::create_shm("my_shm", 4);

- static std::unique_ptr create_shm(const std::string& base_name, size_t max_clients); -}; -``` - -### IpcServer Interface - -```cpp -class IpcServer { -public: - using Handler = std::function(int client_id, std::span request)>; - - virtual ~IpcServer() = default; - - // Start listening for connections - virtual bool listen() = 0; - - // Wait for data from any client (spins then blocks, returns client_id) - virtual int wait_for_data(uint64_t spin_ns) = 0;

// Removes doorbell + 3 rings -``` - -## Implementation Details - -### Memory Layout - -The shared memory region contains: -1. **SpscCtrl** (control block, 256 bytes) - - Atomic head/tail counters (cache-line aligned) - - Futex sequencers for sleep/wake - - Capacity and mask (immutable) -2. **Data buffer** (power-of-2 size, follows control block) - -Total size: `sizeof(SpscCtrl) + capacity` - -### Padding and Wrapping - -When a message would wrap around the ring boundary, automatic padding is inserted: - -``` -┌────────────────────────────────────────────────┐ -│ [msg1] [msg2] [...............] [padding] │ -│ ^ │ -│ └─ wrap point │ -└────────────────────────────────────────────────┘ - ^ - └─ next message starts at beginning -``` - -The consumer's `peek()` automatically skips padding, so callers never see it. - -### Futex-Based Blocking - -Instead of busy-waiting forever: -1. **Producer**: Spins briefly checking for space, then sleeps on `space_seq` futex -2. **Consumer**: Spins briefly checking for data, then sleeps on `data_seq` futex -3. **Wakeup**: Incrementing sequencer + `futex_wake` wakes sleeping side - -This provides: -- Low latency when active (spin catches transitions) -- Low power when idle (futex sleep) -- No thundering herd (one waker, one sleeper) - -### MPSC Doorbell - -The doorbell is a simple futex counter in shared memory: - -```cpp -struct alignas(64) MpscDoorbell { - std::atomic seq; - uint8_t _pad[60]; // Cache line padding -}; -``` - -**Protocol:** -1. Producer publishes data to its SPSC ring -2. If ring was empty (first message), increment doorbell seq and call `futex_wake` -3. Consumer wakes up, polls all rings in round-robin -4. Consumer sleeps on doorbell only when all rings are empty - -This ensures the consumer wakes promptly when any producer has data, while minimizing futex overhead when rings stay populated. - -## Performance Tuning - -### Spin Time - -The `spin_ns` parameter controls busy-wait duration before sleeping: - -- **Low latency**: Use longer spin (e.g., 100 µs) to avoid futex overhead -- **Power efficiency**: Use shorter spin (e.g., 1 µs) to sleep sooner -- **Recommended**: 10-20 µs balances latency and power - -### Ring Size - -- Must be **power of two** -- Larger rings reduce wrapping overhead but use more memory -- Recommended: 1 MB (1 << 20) for most use cases -- Small messages (<1 KB): Can use smaller rings (256 KB) -- Large messages (>100 KB): Use larger rings (4-16 MB) - -### Number of Producers (MPSC) - -- More producers → more ring poll overhead for consumer -- Recommended: ≤8 producers for best performance -- Beyond that, consider multiple MPSC systems or alternative architecture - -## Thread Safety - -### SPSC -- **One producer thread**, **one consumer thread** -- No internal synchronization needed (lock-free by design) -- Cannot share producer or consumer role across threads - -### MPSC -- **Multiple producer threads** (one per producer instance) -- **One consumer thread** -- Each producer is independent (no contention) -- Consumer must be single-threaded - -## Limitations - -1. **Platform**: Linux-only (uses futex, though portable to other POSIX with modifications) -2. **Capacity**: Must be power of two -3. **Fixed size**: Cannot resize after creation -4. **No security**: All processes with access can read/write shared memory -5. **Manual cleanup**: Must call `unlink()` to remove `/dev/shm` objects - -## Comparison with Other IPC Mechanisms - -| Mechanism | Latency | Throughput | Complexity | Use Case | -|--------------------|------------|------------|------------|-------------------------| -| Pipe | 6-15 µs | 150K/s | Low | Simple IPC | -| Unix Socket | 6-15 µs | 150K/s | Low | Network-like API | -| SPSC Ring | 0.3-1 µs | 1M/s | Medium | Ultra-low latency | -| MPSC Ring | ~3 µs | 700K/s | Medium | Multiple producers | -| POSIX MQ | 10-20 µs | 100K/s | Medium | Message queue semantics | - -## See Also - -- Parent IPC module: [`../README.md`](../README.md) -- Tests: [`../shm.test.cpp`](../shm.test.cpp) -- Benchmarks: `barretenberg/cpp/build-no-avm/bin/ipc_bench` -- Higher-level wrappers: `ShmClient` / `ShmServer` in [`../shm_client.hpp`](../shm_client.hpp) - -## License - -Part of Barretenberg cryptographic library. -See repository root for license details. diff --git a/barretenberg/cpp/src/barretenberg/ipc/shm/futex.hpp b/barretenberg/cpp/src/barretenberg/ipc/shm/futex.hpp deleted file mode 100644 index e8c307134b46..000000000000 --- a/barretenberg/cpp/src/barretenberg/ipc/shm/futex.hpp +++ /dev/null @@ -1,111 +0,0 @@ -/** - * @file futex.hpp - * @brief Cross-platform futex-like synchronization primitives - * - * Provides unified wait/wake operations for cross-process synchronization: - * - macOS: Uses os_sync_wait_on_address / os_sync_wake_by_address_any - * - Linux: Uses futex syscalls - */ -#pragma once - -#include -#include - -#ifdef __APPLE__ -// Darwin's os_sync API (available since macOS 10.12 / iOS 10) -// Forward declarations to avoid header dependency -extern "C" { -int os_sync_wait_on_address(void* addr, uint64_t value, size_t size, uint32_t flags); -int os_sync_wait_on_address_with_timeout( - void* addr, uint64_t value, size_t size, uint32_t flags, uint32_t clockid, uint64_t timeout_ns); -int os_sync_wake_by_address_any(void* addr, size_t size, uint32_t flags); -} -#define OS_SYNC_WAIT_ON_ADDRESS_SHARED 1u -#define OS_SYNC_WAKE_BY_ADDRESS_SHARED 1u -#define OS_CLOCK_MACH_ABSOLUTE_TIME 32u -#else -// Linux futex -#include -#include -#include -#include -#endif - -namespace bb::ipc { - -/** - * @brief Atomic compare-and-wait operation - * - * Blocks if the value at addr equals expect.

delete NAPI WSDB MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The C++ AVM (NAPI) used to dereference an in-process `WorldState*` handle (the NAPI External returned by `NativeWorldState`). With WSDB now running as a standalone aztec-wsdb process, that pointer no longer exists. This PR cuts everything over to IPC: C++: - AvmSimAPI::simulate now takes `LowLevelMerkleDBInterface&` instead of `WorldState&`; AvmSimulationHelper::simulate_fast_internal is promoted to public so callers can plug in their own merkle DB. - nodejs_module/avm_simulate accepts a WSDB UDS socket path (string) as its third arg instead of a NAPI External handle, constructs a WsdbIpcClient + WsdbIpcMerkleDB per simulation, and runs the simulation against that. - nodejs_module/world_state/* deleted — there is no in-process WorldState any more. nodejs_module links wsdb_client + wsdb_ipc_client instead. TypeScript (bb.js): - `findWsdbBinary()` added next to `findBbBinary()` / `findNapiBinary()` for resolving the standalone aztec-wsdb binary on disk. TypeScript (yarn-project): - `@aztec/native` no longer exports `NativeWorldState`. `avmSimulate` takes a `wsdbSocketPath: string` instead of `worldStateHandle: any`. - `NativeWorldStateInstance` interface trades `getHandle()` for `getSocketPath()` and gains `close()`. The legacy in-process `NativeWorldState` class in `world-state/src/native/native_world_state_instance.ts` is gone — only `IpcWorldState` remains. - `NativeWorldStateService.new()`/`.tmp()` now spawn aztec-wsdb under the hood and wrap it in `IpcWorldState`. They preserve the existing public API so callers (tests, factories, the node) don't need to change. - `MerkleTreesFacade.getRevision()` returns plain `WorldStateRevision` again; a new `getSocketPath()` exposes the WSDB socket path so the C++ AVM can attach to the same world state instance the TS layer is using. `GuardedMerkleTreeOperations` and `HintingMerkleWriteOperations` proxy `getSocketPath` through. - `CppPublicTxSimulator` and `CppVsTsPublicTxSimulator` ask the merkle tree for its socket path and pass that to `avmSimulate` instead of the removed handle. - `WorldStateRevisionWithHandle` deleted from stdlib. After this PR, the only path between TS and the world state is IPC, and the only path between the C++ AVM and the world state is also IPC. --- .../barretenberg/nodejs_module/CMakeLists.txt | 2 +- .../avm_simulate/avm_simulate_napi.cpp | 31 +- .../avm_simulate/avm_simulate_napi.hpp | 2 +- .../nodejs_module/init_module.cpp | 2 - .../nodejs_module/world_state/world_state.cpp | 977 ------------------ .../nodejs_module/world_state/world_state.hpp | 84 -- .../world_state/world_state_message.hpp | 272 ----- .../cpp/src/barretenberg/vm2/avm_sim_api.cpp | 37 +- .../cpp/src/barretenberg/vm2/avm_sim_api.hpp | 2 +- .../barretenberg/vm2/simulation_helper.hpp | 5 +- .../ts/src/bb_backends/node/platform.ts | 37 + yarn-project/native/src/native_module.ts | 10 +- .../src/public/hinting_db_sources.ts | 4 + .../public_processor/guarded_merkle_tree.ts | 7 +- .../cpp_public_tx_simulator.ts | 15 +- .../cpp_vs_ts_public_tx_simulator.ts | 13 +- .../src/interfaces/merkle_tree_operations.ts | 11 +- .../src/world-state/world_state_revision.ts | 33 - .../src/native/ipc_world_state_instance.ts | 703 +++++++++++++ .../src/native/merkle_trees_facade.ts | 10 +- .../src/native/native_world_state.ts | 152 ++- .../src/native/native_world_state_instance.ts | 311 +----- 22 files changed, 981 insertions(+), 1739 deletions(-) delete mode 100644 barretenberg/cpp/src/barretenberg/nodejs_module/world_state/world_state.cpp delete mode 100644 barretenberg/cpp/src/barretenberg/nodejs_module/world_state/world_state.hpp delete mode 100644 barretenberg/cpp/src/barretenberg/nodejs_module/world_state/world_state_message.hpp create mode 100644 yarn-project/world-state/src/native/ipc_world_state_instance.ts diff --git a/barretenberg/cpp/src/barretenberg/nodejs_module/CMakeLists.txt b/barretenberg/cpp/src/barretenberg/nodejs_module/CMakeLists.txt index 171a732ab04a..21676737c2ae 100644 --- a/barretenberg/cpp/src/barretenberg/nodejs_module/CMakeLists.txt +++ b/barretenberg/cpp/src/barretenberg/nodejs_module/CMakeLists.txt @@ -27,7 +27,7 @@ string(REGEX REPLACE "[\r\n\"]" "" NODE_API_HEADERS_DIR ${NODE_API_HEADERS_DIR}) add_library(nodejs_module SHARED ${SOURCE_FILES}) set_target_properties(nodejs_module PROPERTIES PREFIX "" SUFFIX ".node") target_include_directories(nodejs_module PRIVATE ${NODE_API_HEADERS_DIR} ${NODE_ADDON_API_DIR}) -target_link_libraries(nodejs_module PRIVATE world_state ipc_runtime vm2_sim) +target_link_libraries(nodejs_module PRIVATE ipc_runtime vm2_sim) # On macOS, Node.js N-API symbols are provided by the runtime, not at link time if(CMAKE_SYSTEM_NAME STREQUAL "Darwin") diff --git a/barretenberg/cpp/src/barretenberg/nodejs_module/avm_simulate/avm_simulate_napi.cpp b/barretenberg/cpp/src/barretenberg/nodejs_module/avm_simulate/avm_simulate_napi.cpp index 01c19f45e6b5..97ed8370a104 100644 --- a/barretenberg/cpp/src/barretenberg/nodejs_module/avm_simulate/avm_simulate_napi.cpp +++ b/barretenberg/cpp/src/barretenberg/nodejs_module/avm_simulate/avm_simulate_napi.cpp @@ -5,6 +5,7 @@ #include #include "barretenberg/common/log.hpp" +#include "barretenberg/ipc/ipc_client.hpp" #include "barretenberg/nodejs_module/avm_simulate/ts_callback_contract_db.hpp" #include "barretenberg/nodejs_module/util/async_op.hpp" #include "barretenberg/serialize/msgpack.hpp" @@ -12,6 +13,8 @@ #include "barretenberg/vm2/avm_sim_api.hpp" #include "barretenberg/vm2/common/avm_io.hpp" #include "barretenberg/vm2/simulation/lib/cancellation_token.hpp" +#include "barretenberg/wsdb/wsdb_ipc_client_generated.hpp" +#include "barretenberg/wsdb_client/wsdb_ipc_merkle_db.hpp" namespace bb::nodejs { namespace { @@ -227,15 +230,13 @@ Napi::Value AvmSimulateNapi::simulate(const Napi::CallbackInfo& cb_info) env, ContractCallbacks::get(contract_provider, CALLBACK_REVERT_CHECKPOINT), CALLBACK_REVERT_CHECKPOINT), };
