From 53f5b0f32fbb716663766ed0412627bfcf2c79b8 Mon Sep 17 00:00:00 2001 From: Farhan Syah Date: Wed, 15 Apr 2026 19:59:53 +0800 Subject: [PATCH 01/11] refactor(cluster): split rpc_codec.rs into per-concern module The monolithic rpc_codec.rs (955 lines) is replaced with a module directory subdivided by message category: raft_msgs, raft_rpc, cluster_mgmt, vshard, execute, header, and discriminants. This keeps each encode/decode concern self-contained and below the 500-line file limit, making it straightforward to extend individual message groups without touching unrelated codec paths. Raft loop internals (handle_rpc, join, loop_core, tick) and cluster_info are updated to import from the new module paths. --- nodedb-cluster/src/cluster_info.rs | 8 +- nodedb-cluster/src/forward.rs | 60 +- nodedb-cluster/src/lib.rs | 2 +- nodedb-cluster/src/raft_loop/handle_rpc.rs | 13 +- nodedb-cluster/src/raft_loop/join.rs | 4 +- nodedb-cluster/src/raft_loop/loop_core.rs | 56 +- nodedb-cluster/src/raft_loop/tick.rs | 4 +- nodedb-cluster/src/rpc_codec.rs | 955 ------------------ nodedb-cluster/src/rpc_codec/cluster_mgmt.rs | 215 ++++ nodedb-cluster/src/rpc_codec/discriminants.rs | 31 + nodedb-cluster/src/rpc_codec/execute.rs | 305 ++++++ nodedb-cluster/src/rpc_codec/header.rs | 103 ++ nodedb-cluster/src/rpc_codec/metadata.rs | 89 ++ nodedb-cluster/src/rpc_codec/mod.rs | 27 + nodedb-cluster/src/rpc_codec/raft_msgs.rs | 297 ++++++ nodedb-cluster/src/rpc_codec/raft_rpc.rs | 190 ++++ nodedb-cluster/src/rpc_codec/vshard.rs | 20 + nodedb-cluster/tests/common/mod.rs | 14 +- 18 files changed, 1351 insertions(+), 1042 deletions(-) delete mode 100644 nodedb-cluster/src/rpc_codec.rs create mode 100644 nodedb-cluster/src/rpc_codec/cluster_mgmt.rs create mode 100644 nodedb-cluster/src/rpc_codec/discriminants.rs create mode 100644 nodedb-cluster/src/rpc_codec/execute.rs create mode 100644 nodedb-cluster/src/rpc_codec/header.rs create mode 100644 nodedb-cluster/src/rpc_codec/metadata.rs create mode 100644 nodedb-cluster/src/rpc_codec/mod.rs create mode 100644 nodedb-cluster/src/rpc_codec/raft_msgs.rs create mode 100644 nodedb-cluster/src/rpc_codec/raft_rpc.rs create mode 100644 nodedb-cluster/src/rpc_codec/vshard.rs diff --git a/nodedb-cluster/src/cluster_info.rs b/nodedb-cluster/src/cluster_info.rs index bed68a3a..99de757d 100644 --- a/nodedb-cluster/src/cluster_info.rs +++ b/nodedb-cluster/src/cluster_info.rs @@ -13,7 +13,7 @@ use std::sync::{Arc, RwLock}; use serde::{Deserialize, Serialize}; -use crate::forward::RequestForwarder; +use crate::forward::PlanExecutor; use crate::lifecycle_state::{ClusterLifecycleState, ClusterLifecycleTracker}; use crate::multi_raft::GroupStatus; use crate::raft_loop::{CommitApplier, RaftLoop}; @@ -25,16 +25,16 @@ use crate::topology::ClusterTopology; /// Implemented for every `RaftLoop` via a blanket impl so the main /// binary can coerce `Arc>` to `Arc` without thinking about the -/// `CommitApplier` / `RequestForwarder` type parameters. +/// `CommitApplier` / `PlanExecutor` type parameters. pub trait GroupStatusProvider: Send + Sync { /// Current status of every Raft group hosted on this node. fn group_statuses(&self) -> Vec; } -impl GroupStatusProvider for RaftLoop +impl GroupStatusProvider for RaftLoop where A: CommitApplier, - F: RequestForwarder, + P: PlanExecutor, { fn group_statuses(&self) -> Vec { RaftLoop::group_statuses(self) diff --git a/nodedb-cluster/src/forward.rs b/nodedb-cluster/src/forward.rs index 8cf6346b..093e0152 100644 --- a/nodedb-cluster/src/forward.rs +++ b/nodedb-cluster/src/forward.rs @@ -1,40 +1,40 @@ -//!

A new wire.rs module provides the ExecuteRequest/ExecuteResponse envelope types used by the gateway to ship pre-planned physical plans over QUIC instead of forwarding raw SQL strings. Protocol changes: - Add Status opcode (0x03) to OpCode for unauthenticated readiness checks - Add TryFrom/From impls for serde-compatible JSON numeric encoding - Add MessagePack derivations to shared types (Value, graph, timeseries) --- nodedb-query/src/expr/types.rs | 6 +- nodedb-types/src/graph.rs | 14 +- nodedb-types/src/protocol.rs | 102 ++++++- nodedb-types/src/timeseries/continuous_agg.rs | 30 ++- nodedb-types/src/value.rs | 7 + nodedb/src/bridge/physical_plan/columnar.rs | 10 +- nodedb/src/bridge/physical_plan/crdt.rs | 10 +- nodedb/src/bridge/physical_plan/document.rs | 84 +++++- nodedb/src/bridge/physical_plan/graph.rs | 14 +- nodedb/src/bridge/physical_plan/kv.rs | 10 +- nodedb/src/bridge/physical_plan/meta.rs | 10 +- nodedb/src/bridge/physical_plan/mod.rs | 12 +- nodedb/src/bridge/physical_plan/query.rs | 30 ++- nodedb/src/bridge/physical_plan/spatial.rs | 23 +- nodedb/src/bridge/physical_plan/text.rs | 16 +- nodedb/src/bridge/physical_plan/timeseries.rs | 10 +- nodedb/src/bridge/physical_plan/vector.rs | 22 +- nodedb/src/bridge/physical_plan/wire.rs | 254 ++++++++++++++++++ 18 files changed, 620 insertions(+), 44 deletions(-) create mode 100644 nodedb/src/bridge/physical_plan/wire.rs diff --git a/nodedb-query/src/expr/types.rs b/nodedb-query/src/expr/types.rs index 92d8d332..a3b65428 100644 --- a/nodedb-query/src/expr/types.rs +++ b/nodedb-query/src/expr/types.rs @@ -3,7 +3,7 @@ use nodedb_types::Value; /// A serializable SQL expression that can be evaluated against a document. -#[derive(Debug, Clone, serde::Serialize, serde::Deserialize)] +#[derive(Debug, Clone, PartialEq, serde::Serialize, serde::Deserialize)] pub enum SqlExpr { /// Column reference: extract field value from the document.

charset=UTF-8 Content-Transfer-Encoding: 8bit The previous startup sequencer used an atomic phase counter with watch channels and a monolithic Sequencer struct. This is replaced by StartupSequencer (startup_sequencer.rs) which models each phase as a named gate — a tokio Notify pair registered before the owning subsystem begins its work and fired immediately after it reports ready. Benefits: - Phase transitions are observable without polling: await_phase() is a zero-cost future on the gate's notifier - Multiple concurrent subsystems can own separate gates within the same phase and the phase only advances when all registered gates have fired - The GatewayGuard and startup snapshot are folded into the new health.rs module, removing guard.rs and snapshot.rs - Eliminates sequencer.rs (411 lines) and guard.rs (207 lines) SharedState is updated to hold Arc so listeners installed at different points in startup all see live phase transitions. --- nodedb/src/control/startup/error.rs | 76 ++- nodedb/src/control/startup/gate.rs | 274 ++++++++ nodedb/src/control/startup/guard.rs | 207 ------ nodedb/src/control/startup/health.rs | 162 +++++ nodedb/src/control/startup/mod.rs | 32 +- nodedb/src/control/startup/phase.rs | 60 +- nodedb/src/control/startup/sequencer.rs | 411 ------------ nodedb/src/control/startup/snapshot.rs | 133 ---- .../src/control/startup/startup_sequencer.rs | 611 ++++++++++++++++++ nodedb/src/control/state/fields.rs | 32 +- nodedb/src/control/state/init.rs | 18 +- 11 files changed, 1188 insertions(+), 828 deletions(-) create mode 100644 nodedb/src/control/startup/gate.rs delete mode 100644 nodedb/src/control/startup/guard.rs create mode 100644 nodedb/src/control/startup/health.rs delete mode 100644 nodedb/src/control/startup/sequencer.rs delete mode 100644 nodedb/src/control/startup/snapshot.rs create mode 100644 nodedb/src/control/startup/startup_sequencer.rs diff --git a/nodedb/src/control/startup/error.rs b/nodedb/src/control/startup/error.rs index d7c98b4a..023b041d 100644 --- a/nodedb/src/control/startup/error.rs +++ b/nodedb/src/control/startup/error.rs @@ -1,43 +1,61 @@ -//!

The flat ShutdownWatch is preserved as the underlying signal so all existing watch::Receiver subscribers continue to work without change. --- nodedb/src/control/shutdown/bus.rs | 503 +++++++++++++++++++++++++++ nodedb/src/control/shutdown/mod.rs | 4 + nodedb/src/control/shutdown/phase.rs | 129 +++++++ 3 files changed, 636 insertions(+) create mode 100644 nodedb/src/control/shutdown/bus.rs create mode 100644 nodedb/src/control/shutdown/phase.rs diff --git a/nodedb/src/control/shutdown/bus.rs b/nodedb/src/control/shutdown/bus.rs new file mode 100644 index 00000000..2808115e --- /dev/null +++ b/nodedb/src/control/shutdown/bus.rs @@ -0,0 +1,503 @@ +//!

CDC consume_remote and topic publish are updated to route through gateway.execute_sql instead of the old ForwardRequest path. --- nodedb/src/control/cluster_forwarder.rs | 134 ----- nodedb/src/control/exec_receiver.rs | 179 +++++++ nodedb/src/control/forward.rs | 146 ----- nodedb/src/control/gateway/cache_miss.rs | 142 +++++ nodedb/src/control/gateway/core.rs | 501 ++++++++++++++++++ nodedb/src/control/gateway/dispatcher.rs | 237 +++++++++ nodedb/src/control/gateway/error_map.rs | 340 ++++++++++++ nodedb/src/control/gateway/fuser.rs | 189 +++++++ nodedb/src/control/gateway/invalidation.rs | 105 ++++ nodedb/src/control/gateway/mod.rs | 18 + nodedb/src/control/gateway/plan_cache.rs | 338 ++++++++++++ nodedb/src/control/gateway/retry.rs | 189 +++++++ nodedb/src/control/gateway/route.rs | 71 +++ nodedb/src/control/gateway/router.rs | 198 +++++++ nodedb/src/control/gateway/version_set.rs | 380 +++++++++++++ nodedb/src/control/mod.rs | 6 +- nodedb/src/control/scatter_gather.rs | 89 ++-- .../src/control/server/http/routes/query.rs | 149 ++++-- .../src/control/server/http/routes/ws_rpc.rs | 66 ++- nodedb/src/control/server/http/server.rs | 110 +++- nodedb/src/control/server/ilp_listener.rs | 84 ++- nodedb/src/control/server/listener.rs | 39 +- .../server/native/dispatch/direct_ops.rs | 61 ++- .../src/control/server/native/dispatch/mod.rs | 1 + .../src/control/server/native/dispatch/sql.rs | 86 +-- .../server/native/dispatch/sql_gateway.rs | 76 +++ .../server/native/dispatch/transaction.rs | 55 +- nodedb/src/control/server/native/session.rs | 11 +- .../server/pgwire/ddl/dsl/search_fusion.rs | 2 +- .../server/pgwire/ddl/dsl/search_vector.rs | 6 +- .../server/pgwire/ddl/stream_select.rs | 2 +- .../src/control/server/pgwire/handler/plan.rs | 5 + .../control/server/pgwire/handler/retry.rs | 110 ---- .../server/pgwire/handler/routing/forward.rs | 182 ------- .../handler/routing/gateway_dispatch.rs | 125 +++++ .../server/pgwire/handler/routing/mod.rs | 18 +- nodedb/src/control/server/pgwire/listener.rs | 45 +- .../control/server/resp/gateway_dispatch.rs | 127 +++++ nodedb/src/control/server/resp/handler.rs | 60 +-- nodedb/src/control/server/resp/listener.rs | 20 +- nodedb/src/control/server/resp/mod.rs | 1 + nodedb/src/control/server/session.rs | 4 +- nodedb/src/event/cdc/consume.rs | 128 +++-- nodedb/src/event/topic/publish.rs | 62 ++- 44 files changed, 3923 insertions(+), 974 deletions(-) delete mode 100644 nodedb/src/control/cluster_forwarder.rs create mode 100644 nodedb/src/control/exec_receiver.rs delete mode 100644 nodedb/src/control/forward.rs create mode 100644 nodedb/src/control/gateway/cache_miss.rs create mode 100644 nodedb/src/control/gateway/core.rs create mode 100644 nodedb/src/control/gateway/dispatcher.rs create mode 100644 nodedb/src/control/gateway/error_map.rs create mode 100644 nodedb/src/control/gateway/fuser.rs create mode 100644 nodedb/src/control/gateway/invalidation.rs create mode 100644 nodedb/src/control/gateway/mod.rs create mode 100644 nodedb/src/control/gateway/plan_cache.rs create mode 100644 nodedb/src/control/gateway/retry.rs create mode 100644 nodedb/src/control/gateway/route.rs create mode 100644 nodedb/src/control/gateway/router.rs create mode 100644 nodedb/src/control/gateway/version_set.rs create mode 100644 nodedb/src/control/server/native/dispatch/sql_gateway.rs delete mode 100644 nodedb/src/control/server/pgwire/handler/routing/forward.rs create mode 100644 nodedb/src/control/server/pgwire/handler/routing/gateway_dispatch.rs create mode 100644 nodedb/src/control/server/resp/gateway_dispatch.rs diff --git a/nodedb/src/control/cluster_forwarder.rs b/nodedb/src/control/cluster_forwarder.rs deleted file mode 100644 index 7020fb24..00000000 --- a/nodedb/src/control/cluster_forwarder.rs +++ /dev/null @@ -1,134 +0,0 @@ -//!

Additional bootstrap changes: - WAL validation runs before wal_gate fires; corrupt segments are now fatal rather than silently ignored, preventing startup on a corrupted WAL - WAL replay failure is now fatal (was a warn + empty state) - ShutdownBus is wired with system metrics for per-phase drain telemetry - A NODEDB_TEST_SLOW_DRAIN_TASK env hook enables drain-abort integration tests Supporting changes: - recovery_check module added for catalog sanity check on startup - catalog_entry post_apply and invalidation tests updated - system metrics expanded for startup and shutdown phase telemetry - WAL manager gains validate_for_startup - Error types extended for new startup and gateway error variants --- nodedb/Cargo.toml | 1 + .../control/catalog_entry/post_apply/mod.rs | 177 +++++++++

When the checker detects divergence between the in-memory registry and the redb system catalog, it loads a fresh store from redb and calls clear_and_install_from to repair in place, keeping all existing Arc references stable so listeners need not be restarted. --- nodedb/src/control/security/apikey.rs | 13 ++++ .../src/control/security/blacklist/store.rs | 24 ++++++ .../catalog/collection_constraints.rs | 6 +- .../control/security/credential/store/list.rs | 31 ++++++++ .../src/control/security/permission/store.rs | 77 +++++++++++++++++++ nodedb/src/control/security/rls/store.rs | 30 ++++++++ nodedb/src/control/security/role.rs | 14 ++++ nodedb/src/control/trigger/registry.rs | 45 +++++++++++ .../timeseries/retention_policy/registry.rs | 26 +++++++ nodedb/src/event/alert/registry.rs | 21 +++++ .../src/event/cdc/consumer_group/registry.rs | 25 ++++++ nodedb/src/event/cdc/registry.rs | 21 +++++ nodedb/src/event/consumer.rs | 9 +++ nodedb/src/event/plane.rs | 63 ++++++++++----- nodedb/src/event/scheduler/registry.rs | 22 ++++++ nodedb/src/event/streaming_mv/registry.rs | 24 ++++++ 16 files changed, 428 insertions(+), 23 deletions(-) diff --git a/nodedb/src/control/security/apikey.rs b/nodedb/src/control/security/apikey.rs index f72565d3..0f004f67 100644 --- a/nodedb/src/control/security/apikey.rs +++ b/nodedb/src/control/security/apikey.rs @@ -137,6 +137,19 @@ impl ApiKeyStore { Ok(()) } + /// Clear the in-memory key map and re-run `load_from`. + /// Used by the catalog recovery sanity checker to repair + /// a divergent registry. + pub(crate) fn clear_and_reload(&self, catalog: &SystemCatalog) -> crate::Result<()> { + { + let mut keys = self.keys.write().map_err(|e| crate::Error::Internal { + detail: format!("api key lock poisoned during repair: {e}"), + })?; + keys.clear(); + } + self.load_from(catalog) + } + /// Persist a single key record to the catalog. fn persist_to(&self, catalog: &SystemCatalog, record: &ApiKeyRecord) -> crate::Result<()> { catalog.put_api_key(&record.to_stored()) diff --git a/nodedb/src/control/security/blacklist/store.rs b/nodedb/src/control/security/blacklist/store.rs index 9747ebad..b7e549b5 100644 --- a/nodedb/src/control/security/blacklist/store.rs +++ b/nodedb/src/control/security/blacklist/store.rs @@ -281,6 +281,30 @@ impl BlacklistStore { .collect() } + /// All in-memory entries (including potentially expired ones that + /// haven't been lazily evicted yet).

Real-listener NotLeader retry tests — C-δ.8 rewrite of the old mock-closure tests. +//! +//! ## Design rationale +//! +//! The previous tests (C-δ.6) exercised the `retry_not_leader` helper with a +//! mock closure that returned `Err(NotLeader)` on attempt 0. That proved the +//! **retry mechanic itself** works, but it did NOT prove that any listener's +//! handler code actually routes through `shared.gateway` and triggers the retry +//! path under a real `NotLeader` condition. +//! +//! This rewrite: +//! 1. Uses `node.shared.gateway` (the gateway installed during harness setup), +//! not a fresh `Gateway::new(node.shared)`. +//! 2. Issues real gateway executions through the installed gateway and asserts +//! the correct counter state. +//! 3. Documents WHY the real-listener NotLeader-trigger path is not exercisable +//! end-to-end via listener connections, and provides the appropriate +//! substitute proof per the C-δ.8 spec. +//! +//! ## Why "NotLeader retry not applicable via protocol client" for all 5 listeners +//! +//! The current `ExecuteRequest` + `LocalPlanExecutor` pipeline does NOT emit +//! `TypedClusterError::NotLeader` in the response. `LocalPlanExecutor::execute_plan` +//! (in `exec_receiver.rs`) only returns `DescriptorMismatch`, `DeadlineExceeded`, +//! or `Internal` — never `NotLeader`. The `Error::NotLeader` variant is only +//! produced by the **transport layer** (dispatcher line: "map transport error → +//! NotLeader") when the QUIC connection itself fails (e.g. sending to a node that +//! doesn't exist). In that case the hinted leader in the error is the bad node_id +//! itself, so the retry loop would update the routing table to the same bad node +//! and exhaust all 3 attempts — the client sees `NotLeader`, not success. +//! +//! The retry-on-success path exists for a FUTURE scenario where Raft-aware +//! execution on follower nodes explicitly returns `TypedClusterError::NotLeader` +//! with a real leader hint. That path is not yet wired (no follower Raft check in +//! `handle_rpc.rs::RaftRpc::ExecuteRequest` arm). Until it is, the only valid +//! proof of the retry mechanic is: +//! a) The `retry_not_leader` unit tests in `gateway/retry.rs` (mock closure). +//! b) The gateway-level dispatch tests that prove `shared.gateway` is the +//! installed instance (not a fresh one) and that `not_leader_retry_count()` +//! is observable. +//! +//! For each listener we add: +//! - A test that routes a query through `shared.gateway` (the installed gateway). +//! - An assertion that `not_leader_retry_count() == 0` (single-node, +//! no cross-node dispatch, no NotLeader expected). +//! - A proof that `shared.gateway` is the SAME instance as the one used by +//! the listener handlers: we insert a plan-cache entry directly via +//! `shared.gateway.plan_cache`, then assert the cache size is observable +//! from the same `shared.gateway` reference. +//! - For pgwire: a real tokio_postgres query that goes through the listener +//! and returns successfully. +//! - For HTTP/RESP/ILP/native: the test harness doesn't bind those listeners, +//! so we exercise the gateway-level error mapping for each protocol's +//! `GatewayErrorMap::to_` function instead. + +mod common; + +use std::sync::Arc; +use std::time::Duration; + +use nodedb::Error; +use nodedb::bridge::physical_plan::{KvOp, PhysicalPlan}; +use nodedb::control::gateway::GatewayErrorMap; +use nodedb::control::gateway::core::QueryContext; +use nodedb::types::{TenantId, VShardId}; + +use common::cluster_harness::TestClusterNode; + +fn test_ctx() -> QueryContext { + QueryContext { + tenant_id: TenantId::new(0), + trace_id: 0xC0DE_DE16, + } +} + +fn mp_string(s: &str) -> Vec { + zerompk::to_msgpack_vec(&nodedb_types::Value::String(s.into())).expect("encode string value") +} + +// ───────────────────────────────────────────────────────────────────────────── +// pgwire — real listener, real tokio_postgres query +// +// NotLeader retry not applicable via pgwire protocol: LocalPlanExecutor does +// not emit TypedClusterError::NotLeader.
