From 508f9bd384082492cf9545b5d329487398db7871 Mon Sep 17 00:00:00 2001 From: Farhan Syah Date: Fri, 15 May 2026 15:25:52 +0800 Subject: [PATCH 01/83] refactor(nodedb): split trait_impl into focused submodules Replace the single monolithic trait_impl.rs (564 lines) with a trait_impl/ directory containing document.rs, graph.rs, vector.rs, dispatch.rs, sql_lifecycle.rs, and mod.rs. Each file covers one logical slice of the NodeDb trait implementation. Array CRDT sync state (array_replica, array_schemas, array_outbound, array_inbound, array_catchup) is now gated behind `#[cfg(not(target_arch = "wasm32"))]` to allow the same codebase to compile for native and WASM targets. Fix CsrIndex checkpoint deserialization to use the fallible `from_checkpoint` path (returns `Result>`) instead of the deprecated infallible unwrap variant. --- nodedb-lite/src/nodedb/array.rs | 25 +- nodedb-lite/src/nodedb/batch.rs | 3 +- nodedb-lite/src/nodedb/convert.rs | 3 +- nodedb-lite/src/nodedb/core.rs | 66 +- nodedb-lite/src/nodedb/graph_rag.rs | 12 +- nodedb-lite/src/nodedb/health.rs | 5 +- nodedb-lite/src/nodedb/mod.rs | 58 +- nodedb-lite/src/nodedb/sync_delegate.rs | 2 + nodedb-lite/src/nodedb/trait_impl.rs | 564 ------------------ nodedb-lite/src/nodedb/trait_impl/dispatch.rs | 192 ++++++ nodedb-lite/src/nodedb/trait_impl/document.rs | 80 +++ nodedb-lite/src/nodedb/trait_impl/graph.rs | 262 ++++++++ nodedb-lite/src/nodedb/trait_impl/mod.rs | 13 + .../src/nodedb/trait_impl/sql_lifecycle.rs | 72 +++ nodedb-lite/src/nodedb/trait_impl/vector.rs | 268 +++++++++ 15 files changed, 1015 insertions(+), 610 deletions(-) delete mode 100644 nodedb-lite/src/nodedb/trait_impl.rs create mode 100644 nodedb-lite/src/nodedb/trait_impl/dispatch.rs create mode 100644 nodedb-lite/src/nodedb/trait_impl/document.rs create mode 100644 nodedb-lite/src/nodedb/trait_impl/graph.rs create mode 100644 nodedb-lite/src/nodedb/trait_impl/mod.rs create mode 100644 nodedb-lite/src/nodedb/trait_impl/sql_lifecycle.rs create mode 100644 nodedb-lite/src/nodedb/trait_impl/vector.rs diff --git a/nodedb-lite/src/nodedb/array.rs b/nodedb-lite/src/nodedb/array.rs index 0cc854b..8907119 100644 --- a/nodedb-lite/src/nodedb/array.rs +++ b/nodedb-lite/src/nodedb/array.rs @@ -8,6 +8,7 @@ use nodedb_array::schema::ArraySchema; use nodedb_array::tile::cell_payload::CellPayload; use nodedb_array::types::cell_value::value::CellValue; use nodedb_array::types::coord::value::CoordValue; +#[cfg(not(target_arch = "wasm32"))] use nodedb_types::OPEN_UPPER; use nodedb_types::error::{NodeDbError, NodeDbResult}; @@ -30,9 +31,13 @@ impl NodeDbLite { .map_err(NodeDbError::storage)?; // Register the schema CRDT so subsequent emit_* calls can find schema_hlc. + #[cfg(not(target_arch = "wasm32"))] self.array_schemas .put_schema(name, &schema_for_crdt) .map_err(NodeDbError::storage)?; + // On wasm, schema registration is skipped (sync not available). + #[cfg(target_arch = "wasm32")] + let _ = schema_for_crdt; Ok(()) } @@ -68,10 +73,8 @@ impl NodeDbLite { ) .map_err(NodeDbError::storage)?; - // Emit op after engine succeeds.

This aligns the graph API with the rest of the NodeDb trait where every operation is scoped to a named collection. The change propagates through all binding layers: - C FFI (nodedb_lite.h, ffi_graph.rs, jni_bridge) - WASM bindings (graphInsertEdge, graphTraverse, graphDeleteEdge, graphShortestPath, graphStats) - Integration and e2e test suites NodeId construction switches from the infallible NodeId::new to the validated NodeId::try_new / NodeId::from_validated path. EdgeId parsing switches from the infallible EdgeId::new to EdgeId::from_str with proper error propagation. Add graphStats to the WASM API surface and add graph_stats_parity test to verify Lite output matches expected structure. --- nodedb-lite-ffi/include/nodedb_lite.h | 24 ++++--- nodedb-lite-ffi/src/ffi_document.rs | 6 ++ nodedb-lite-ffi/src/ffi_graph.rs | 73 ++++++++++++++++----- nodedb-lite-ffi/src/jni_bridge/core.rs | 38 ++++++++--- nodedb-lite-ffi/tests/ffi.rs | 11 +++- nodedb-lite-wasm/src/lib.rs | 84 +++++++++++++++++++------ nodedb-lite-wasm/tests/array.rs | 18 ++++-- nodedb-lite-wasm/tests/browser.rs | 11 ++-- nodedb-lite/tests/e2e.rs | 13 +++- nodedb-lite/tests/graph_stats_parity.rs | 65 +++++++++++++++++++ nodedb-lite/tests/integration.rs | 23 ++++--- 11 files changed, 294 insertions(+), 72 deletions(-) create mode 100644 nodedb-lite/tests/graph_stats_parity.rs diff --git a/nodedb-lite-ffi/include/nodedb_lite.h b/nodedb-lite-ffi/include/nodedb_lite.h index 50871cf..8dccaf3 100644 --- a/nodedb-lite-ffi/include/nodedb_lite.h +++ b/nodedb-lite-ffi/include/nodedb_lite.h @@ -272,6 +272,7 @@ int32_t nodedb_document_delete(struct NodeDbNodeDbHandle *handle, /** * Full-text search (BM25).

Replace every call site with try_encode, which returns Option. In production paths (transport.rs, maintenance.rs) encoding failures are logged and the operation is skipped rather than sending corrupt data. The handshake path treats an encode failure as a hard error and propagates it. Test helpers use .expect() since a failure there indicates a broken test invariant. Replace the hardcoded wire_version literal 1 with the WIRE_FORMAT_VERSION constant from nodedb_types throughout transport, handshake, and examples. --- nodedb-lite/examples/live_sync.rs | 38 ++++++++++++------ nodedb-lite/examples/load_test.rs | 9 +++-- nodedb-lite/src/sync/client/handshake.rs | 3 +- nodedb-lite/src/sync/client/maintenance.rs | 6 +-- nodedb-lite/src/sync/transport.rs | 46 +++++++++++++++++----- 5 files changed, 72 insertions(+), 30 deletions(-) diff --git a/nodedb-lite/examples/live_sync.rs b/nodedb-lite/examples/live_sync.rs index b26ed5a..7bba226 100644 --- a/nodedb-lite/examples/live_sync.rs +++ b/nodedb-lite/examples/live_sync.rs @@ -11,6 +11,7 @@ use tokio_tungstenite::tungstenite::Message;

Columnar store: segment IDs are now u64 in the mutation API; cast u32 segment_id values at all call sites. on_memtable_flushed now returns a Result and is propagated. write_segment and the compaction path accept additional Option parameters. Spatial index: checkpoint_to_bytes and from_checkpoint now take an Option<_> hints argument. Array segments/retention: writer.finish() now takes an Option argument. FTS manager: add a wildcard arm to the query mode match so new variants do not cause a compile error. Catalog: CollectionInfo gains primary and vector_primary fields; populate them at every construction site. SqlCatalog::collection_info gains a DatabaseId parameter. Decimal pattern updated to Decimal{..}. column_type_to_sql adds a catch-all bytes arm.

Corresponding array sync and definition sync interop files provide placeholder tests (all #[ignore]) for the transport paths not yet gate-tested against a live Origin node. Update array_sync_* module docs to clearly label them as edge-side simulations that bypass WebSocket transport, and cross-reference the interop placeholders for the real-transport coverage gap.

Origin will replay deltas whose +LSN is greater than `last_seen_lsn`. + +### Future (post-beta) + +A per-collection/per-document clock would allow Origin to resume at finer +granularity and skip replay of already-seen collections. This is a known +improvement area and is not part of the 0.1.0-beta.1 contract. + +### Divergence from field comment + +The `HandshakeMsg.vector_clock` field has a doc comment that says +`"{ collection: { doc_id: lamport_ts } }"`. Lite sends `{ "_global": { peer_hex: counter } }`. +The mismatch is intentional at the implementation level (Origin only takes the +max), but the comment is misleading. The comment should be updated to reflect +that Origin only uses the scalar maximum and that the `_global` encoding is +the accepted Lite contract. This is tracked as a documentation gap, not a bug. + +--- + +## Fork Detection + +Fork detection activates when **both** `lite_id` is non-empty **and** `epoch > 0`. + +| Scenario | Origin response | +|---------------------------------------------------|-----------------------------------------------------| +| `lite_id` empty or `epoch == 0` | Fork detection skipped; session proceeds normally | +| New `lite_id` (never seen before) | Epoch stored; session proceeds normally | +| Same `lite_id`, `epoch > last_seen_epoch` | Epoch updated; session proceeds normally | +| Same `lite_id`, `epoch == last_seen_epoch` | `fork_detected: true`, `success: false` | +| Same `lite_id`, `epoch < last_seen_epoch` | `fork_detected: true`, `success: false` | +| Same `lite_id`, same epoch, clean reconnect | Treated as fork if `epoch_tracker` still holds the same value — Lite must bump epoch on reconnect after write | + +Source: `nodedb/nodedb/src/control/server/sync/session/handshake.rs:173-214`. + +**Important nuance**: the epoch tracker is in-memory (`Mutex>`). +A server restart clears the tracker, so a client reconnecting after an Origin +restart with the same `lite_id` + `epoch` will **not** trigger fork detection +on that reconnect. This is the expected behaviour for the beta. + +--- + +## Resume Semantics + +After a successful handshake, Origin sets `last_seen_lsn` to the maximum +counter from the client's `vector_clock` and uses it as the replay start point. +Deltas with LSN `> last_seen_lsn` are sent to the client; deltas at or below +that mark are skipped. + +Lite's global-clock encoding means the resume point is the **highest counter +Lite has seen across all peers**, not per-collection. This may cause minor +redundant replay in multi-collection scenarios but will never cause a gap. + +--- + +## Trust Mode + +An empty `jwt_token` bypasses JWT validation. Origin creates an identity with +`user_id = 0`, `tenant_id = 0`, role `ReadWrite`. This mode is for +development and integration tests only. Production deployments must provide +a valid JWT. + +Source: `nodedb/nodedb/src/control/server/sync/session/handshake.rs:54-103`. + +--- + +## CollectionPurged (0x14) — Out of Scope for 0.1.0-beta.1 + +### Origin side (wired) + +Origin's event plane broadcasts a `CollectionPurgedMsg` (frame type `0x14`) to +every connected Lite session that has subscribed or pushed deltas to the +affected collection. The broadcast path is: + +1. `DROP COLLECTION` DDL → `catalog_entry/post_apply/async_dispatch/collection.rs` +2. → `crdt_sync/delivery.rs::broadcast_collection_purged()` +3. → encodes `CollectionPurgedMsg { collection, purge_lsn }` and enqueues into + each matching session's control channel. + +`SyncSession::track_collection()` records the `(tenant_id, collection)` pair +on every `DeltaPush` and `ShapeSubscribe` so the broadcast filter is correct. + +### Lite side (not handled for beta) + +Lite's `dispatch_frame` in `sync/transport.rs` does **not** match on +`SyncMessageType::CollectionPurged` (0x14). The frame falls through to the +`_ =>` arm and is logged as "unexpected frame type from Origin". No shape +eviction, no local collection purge, no application notification occurs. + +### Why not tested in 0.1.0-beta.1 + +- Triggering the broadcast requires issuing a `DROP COLLECTION` DDL against + Origin, which requires a pgwire or HTTP control connection. The interop test + harness exposes only the sync WebSocket on port 9090. +- Asserting Lite's current behavior (silent log) would couple tests to log + output rather than observable state. + +### When to promote to in-scope + +When Lite's `dispatch_frame` handles `CollectionPurged` by evicting the +subscribed shape's local state and notifying the application layer, and when +the test harness exposes a pgwire/HTTP endpoint so tests can issue +`DROP COLLECTION` to trigger the broadcast end-to-end. + +--- + +## Definition Sync (EXPERIMENTAL — NOT IN 0.1.0-beta.1) + +Definition sync carries function, trigger, and procedure definitions from +Origin to connected Lite clients via `DefinitionSync` (frame opcode `0x70`, +`SyncMessageType::DefinitionSync`). + +### Lite side (wired, receive-only) + +Lite's `dispatch_frame` in `nodedb-lite/nodedb-lite/src/sync/transport.rs` +matches on `SyncMessageType::DefinitionSync` (lines 317–319) and calls +`delegate.import_definition(&msg)`. `import_definition` is implemented in +`nodedb-lite/nodedb-lite/src/nodedb/sync_delegate.rs` (line 82) and handles +both `"put"` (create/replace) and `"delete"` (drop) actions with msgpack +payloads.

The sync session handler (`session_handler.rs`), the DDL post-apply +dispatcher (`async_dispatch.rs`), and the CRDT delivery path (`dlq.rs`, +`listener.rs`) have no emission path for definition changes. + +### Placeholder tests + +`nodedb-lite/nodedb-lite/tests/definition_sync_interop.rs` contains four +`#[ignore]` tests covering function put, function delete, trigger put, and +procedure put. + +### Promotion criteria + +Definition sync can be promoted from EXPERIMENTAL to PREVIEW when: + +1.

The missing Lite receive path (`SyncMessageType::ArrayDelta` / `ArrayDeltaBatch`) and promotion criteria are recorded in `docs/lite-sync-protocol.md` (Array Sync section) and `docs/lite-support-matrix.md`. - Public documentation aligned with the actual `NodeDb` trait API: method signatures, return types, and error variants match the implementation. - WASM target builds: jemalloc and WAL POSIX-only paths are now gated behind `cfg` flags so `nodedb-lite-wasm` compiles cleanly for `wasm32-unknown-unknown`. - WASM and C FFI bindings updated to the current `NodeDb` trait surface; graph methods are now collection-scoped. diff --git a/Cargo.toml b/Cargo.toml index 15d12d1..6655c54 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -69,6 +69,7 @@ getrandom = { version = "0.3", features = ["std"] } # Testing tempfile = "3" rust_decimal = { version = "1", features = ["serde-with-str"] } +tokio-postgres = { version = "0.7", features = ["with-serde_json-1"] } # WASM bindings wasm-bindgen = "0.2" diff --git a/nodedb-lite/Cargo.toml b/nodedb-lite/Cargo.toml index 2ffa2f1..0a203bc 100644 --- a/nodedb-lite/Cargo.toml +++ b/nodedb-lite/Cargo.toml @@ -58,3 +58,4 @@ futures = { workspace = true } tokio = { workspace = true, features = ["rt", "rt-multi-thread", "macros"] } tempfile = { workspace = true } rust_decimal = { workspace = true } +tokio-postgres = { workspace = true } From eb1ab15eefb24236fce42bb8fceb6980b4074ebd Mon Sep 17 00:00:00 2001 From: Farhan Syah Date: Sat, 16 May 2026 05:55:52 +0800 Subject: [PATCH 13/83] feat(storage): add bounded range scan to StorageEngineSync Add `scan_range_bounded_sync` to the `StorageEngineSync` trait, with a redb implementation that computes namespace-prefixed start/end keys and performs a half-open byte-range scan.

On flush the full in-memory state — posting memtable, surrogate maps, R-trees, and doc-to-entry mappings — is serialized to the respective storage namespace. On open the indices are restored from these checkpoints without re-tokenizing source documents or rebuilding R-trees. The spatial checkpoint also persists the doc_id → entry_id mapping, preventing duplicate R-tree entries on upsert/delete after a cold open. --- nodedb-lite/src/engine/fts/checkpoint.rs | 312 +++++++++++++++++++ nodedb-lite/src/engine/fts/manager.rs | 34 +- nodedb-lite/src/engine/fts/mod.rs | 3 +- nodedb-lite/src/engine/spatial/checkpoint.rs | 189 +++++++++++ nodedb-lite/src/engine/spatial/index.rs | 70 ++++- nodedb-lite/src/engine/spatial/mod.rs | 1 + 6 files changed, 589 insertions(+), 20 deletions(-) create mode 100644 nodedb-lite/src/engine/fts/checkpoint.rs create mode 100644 nodedb-lite/src/engine/spatial/checkpoint.rs diff --git a/nodedb-lite/src/engine/fts/checkpoint.rs b/nodedb-lite/src/engine/fts/checkpoint.rs new file mode 100644 index 0000000..a250cac --- /dev/null +++ b/nodedb-lite/src/engine/fts/checkpoint.rs @@ -0,0 +1,312 @@ +//!

Each queue buffers pending sync frames until the transport loop drains them. Wire `ColumnarEngine` with optional `outbound` and `timeseries_outbound` fields so inserts are automatically enqueued when sync is enabled. The timeseries outbound uses a distinct `TimeseriesPush` frame type to match Origin's separate timeseries engine path. --- nodedb-lite/src/engine/columnar/store.rs | 204 +++++++++++++++++++ nodedb-lite/src/sync/outbound/columnar.rs | 146 ++++++++++++++ nodedb-lite/src/sync/outbound/fts.rs | 162 +++++++++++++++ nodedb-lite/src/sync/outbound/mod.rs | 13 ++ nodedb-lite/src/sync/outbound/queue.rs | 181 +++++++++++++++++ nodedb-lite/src/sync/outbound/spatial.rs | 207 ++++++++++++++++++++ nodedb-lite/src/sync/outbound/timeseries.rs | 142 ++++++++++++++ nodedb-lite/src/sync/outbound/vector.rs | 178 +++++++++++++++++ 8 files changed, 1233 insertions(+) create mode 100644 nodedb-lite/src/sync/outbound/columnar.rs create mode 100644 nodedb-lite/src/sync/outbound/fts.rs create mode 100644 nodedb-lite/src/sync/outbound/mod.rs create mode 100644 nodedb-lite/src/sync/outbound/queue.rs create mode 100644 nodedb-lite/src/sync/outbound/spatial.rs create mode 100644 nodedb-lite/src/sync/outbound/timeseries.rs create mode 100644 nodedb-lite/src/sync/outbound/vector.rs diff --git a/nodedb-lite/src/engine/columnar/store.rs b/nodedb-lite/src/engine/columnar/store.rs index f279d42..a7f6cbe 100644 --- a/nodedb-lite/src/engine/columnar/store.rs +++ b/nodedb-lite/src/engine/columnar/store.rs @@ -25,6 +25,8 @@ use nodedb_types::value::Value; use crate::error::LiteError; use crate::storage::engine::{StorageEngine, WriteOp}; +use crate::sync::ColumnarOutbound; +use crate::sync::outbound::timeseries::TimeseriesOutbound; /// Meta key prefix for columnar schemas. const META_COLUMNAR_SCHEMA_PREFIX: &str = "columnar_schema:"; @@ -61,6 +63,17 @@ type CollectionMap = HashMap>>; pub struct ColumnarEngine { storage: Arc, collections: RwLock, + /// Optional outbound queue for plain columnar insert sync. + /// `None` when sync is disabled or not yet configured. + outbound: Option>, + /// Optional outbound queue for timeseries-profile insert sync. + /// + /// Timeseries collections must use `TimeseriesPush` frames on Origin + /// (the columnar `MutationEngine` and the timeseries engine are separate + /// storage paths on Origin).

Each module has a single responsibility — connection setup, inbound frame dispatch, sync delegate trait, and outbound push loop respectively. Add `pending_array_ack` to `SyncClient` state so successfully applied `ArrayDelta` and `ArrayDeltaBatch` frames generate an `ArrayAckMsg` that the push loop transmits to advance Origin's GC frontier. Expose `replica_id()` on `ArrayInbound` to support ack construction without holding the inbound lock. --- .../src/sync/array/inbound/dispatcher.rs | 7 + nodedb-lite/src/sync/client/receive.rs | 16 +- nodedb-lite/src/sync/client/state.rs | 9 +- nodedb-lite/src/sync/mod.rs | 6 + nodedb-lite/src/sync/transport.rs | 650 ------------------ nodedb-lite/src/sync/transport/connect.rs | 119 ++++ nodedb-lite/src/sync/transport/delegate.rs | 112 +++ nodedb-lite/src/sync/transport/dispatch.rs | 296 ++++++++ nodedb-lite/src/sync/transport/mod.rs | 61 ++ .../src/sync/transport/push/columnar.rs | 68 ++ .../src/sync/transport/push/control.rs | 117 ++++ nodedb-lite/src/sync/transport/push/fts.rs | 84 +++ nodedb-lite/src/sync/transport/push/mod.rs | 118 ++++ nodedb-lite/src/sync/transport/push/send.rs | 54 ++ .../src/sync/transport/push/spatial.rs | 88 +++ .../src/sync/transport/push/timeseries.rs | 123 ++++ nodedb-lite/src/sync/transport/push/vector.rs | 87 +++ nodedb-lite/src/sync/transport/tests.rs | 227 ++++++ 18 files changed, 1590 insertions(+), 652 deletions(-) delete mode 100644 nodedb-lite/src/sync/transport.rs create mode 100644 nodedb-lite/src/sync/transport/connect.rs create mode 100644 nodedb-lite/src/sync/transport/delegate.rs create mode 100644 nodedb-lite/src/sync/transport/dispatch.rs create mode 100644 nodedb-lite/src/sync/transport/mod.rs create mode 100644 nodedb-lite/src/sync/transport/push/columnar.rs create mode 100644 nodedb-lite/src/sync/transport/push/control.rs create mode 100644 nodedb-lite/src/sync/transport/push/fts.rs create mode 100644 nodedb-lite/src/sync/transport/push/mod.rs create mode 100644 nodedb-lite/src/sync/transport/push/send.rs create mode 100644 nodedb-lite/src/sync/transport/push/spatial.rs create mode 100644 nodedb-lite/src/sync/transport/push/timeseries.rs create mode 100644 nodedb-lite/src/sync/transport/push/vector.rs create mode 100644 nodedb-lite/src/sync/transport/tests.rs diff --git a/nodedb-lite/src/sync/array/inbound/dispatcher.rs b/nodedb-lite/src/sync/array/inbound/dispatcher.rs index 7f29e18..8544904 100644 --- a/nodedb-lite/src/sync/array/inbound/dispatcher.rs +++ b/nodedb-lite/src/sync/array/inbound/dispatcher.rs @@ -81,6 +81,13 @@ impl ArrayInbound { } } + /// The stable replica identity for this Lite peer. + /// + /// Used by the transport layer to construct `ArrayAckMsg` bodies. + pub fn replica_id(&self) -> u64 { + self.replica.replica_id().as_u64() + } + /// Drive [`nodedb_array::sync::apply::apply_op`] on a borrowed /// [`LiteApplyEngine`]. pub(super) fn apply_single_op(&self, op: &ArrayOp) -> Result { diff --git a/nodedb-lite/src/sync/client/receive.rs b/nodedb-lite/src/sync/client/receive.rs index 50b6022..98661e9 100644 --- a/nodedb-lite/src/sync/client/receive.rs +++ b/nodedb-lite/src/sync/client/receive.rs @@ -1,7 +1,8 @@ //!

Extend the sync delegate with `handle_array_delta` and `handle_array_delta_batch` handlers. Both decode the incoming op payload to extract the HLC, invoke the inbound apply path, and return an `ArrayAckMsg` on success.

Extract SQL-value coercion into `query::coerce` (single source of truth for `ColumnType` mapping), columnar DML into `query::columnar_dml`, and strict DML into `query::strict_dml`. The query engine now routes INSERT, UPDATE, DELETE, and UPSERT to the correct engine-specific dispatcher based on the `EngineType` in the plan, rather than defaulting to document semantics for all mutations. Add `StrictEngine::list_rows` to expose full-table scans for the strict query path. --- nodedb-lite/src/engine/strict/crud.rs | 18 +++ nodedb-lite/src/query/coerce.rs | 87 +++++++++++++ nodedb-lite/src/query/columnar_dml.rs | 48 +++++++ nodedb-lite/src/query/engine.rs | 157 ++++++++++++++++++----- nodedb-lite/src/query/mod.rs | 3 + nodedb-lite/src/query/strict_dml.rs | 173 ++++++++++++++++++++++++++ 6 files changed, 455 insertions(+), 31 deletions(-) create mode 100644 nodedb-lite/src/query/coerce.rs create mode 100644 nodedb-lite/src/query/columnar_dml.rs create mode 100644 nodedb-lite/src/query/strict_dml.rs diff --git a/nodedb-lite/src/engine/strict/crud.rs b/nodedb-lite/src/engine/strict/crud.rs index 47a7193..f2312e2 100644 --- a/nodedb-lite/src/engine/strict/crud.rs +++ b/nodedb-lite/src/engine/strict/crud.rs @@ -295,6 +295,24 @@ impl StrictEngine { Ok(arrays) } + /// Scan all rows in a collection and decode each to `Vec`. + /// + /// Returns rows in storage key order.

Add FTS persistence tests verifying that index state survives a simulated restart without document re-indexing. Add real-transport array sync interop tests covering multi-op sequences against a live Origin instance. Extend SQL parity suites for strict, columnar, and timeseries DML, negative cases, and UPDATE/DELETE for engine-aware dispatch paths. Update definition sync interop, graph stats parity, HTAP, integration, and existing SQL parity tests to reflect per-collection graph isolation and async query engine signatures. --- nodedb-lite/tests/array_sync_interop_real.rs | 275 ++++++++++++++++ nodedb-lite/tests/definition_sync_interop.rs | 328 ++++++++++++++----- nodedb-lite/tests/fts_persistence.rs | 142 ++++++++ nodedb-lite/tests/graph_engine_gate.rs | 215 ++++++++++++ nodedb-lite/tests/graph_stats_parity.rs | 4 +- nodedb-lite/tests/htap.rs | 5 + nodedb-lite/tests/integration.rs | 16 +- nodedb-lite/tests/kv_engine_gate.rs | 116 +++++++ nodedb-lite/tests/kv_ttl_and_range.rs | 186 +++++++++++ nodedb-lite/tests/spatial_engine_gate.rs | 328 +++++++++++++++++++ nodedb-lite/tests/sql_parity/columnar.rs | 80 +++-- nodedb-lite/tests/sql_parity/negative.rs | 25 ++ nodedb-lite/tests/sql_parity/strict.rs | 194 +++++++++-- nodedb-lite/tests/sql_parity/timeseries.rs | 9 +- nodedb-lite/tests/sync_interop_columnar.rs | 209 ++++++++++++ nodedb-lite/tests/sync_interop_fts.rs | 323 ++++++++++++++++++ nodedb-lite/tests/sync_interop_spatial.rs | 277 ++++++++++++++++ 17 files changed, 2587 insertions(+), 145 deletions(-) create mode 100644 nodedb-lite/tests/array_sync_interop_real.rs create mode 100644 nodedb-lite/tests/fts_persistence.rs create mode 100644 nodedb-lite/tests/graph_engine_gate.rs create mode 100644 nodedb-lite/tests/kv_engine_gate.rs create mode 100644 nodedb-lite/tests/kv_ttl_and_range.rs create mode 100644 nodedb-lite/tests/spatial_engine_gate.rs create mode 100644 nodedb-lite/tests/sync_interop_columnar.rs create mode 100644 nodedb-lite/tests/sync_interop_fts.rs create mode 100644 nodedb-lite/tests/sync_interop_spatial.rs diff --git a/nodedb-lite/tests/array_sync_interop_real.rs b/nodedb-lite/tests/array_sync_interop_real.rs new file mode 100644 index 0000000..7377b79 --- /dev/null +++ b/nodedb-lite/tests/array_sync_interop_real.rs @@ -0,0 +1,275 @@ +//!

Add a vector engine gate suite covering HNSW insert, nearest-neighbor search, and delete across collections. Expand the sync protocol spec with outbound queue semantics, per-engine frame types, and array ack flow. Update the SQL support matrix to reflect columnar, strict, and timeseries DML coverage in the query engine.

WASM (`nodedb-lite-wasm`) is preview — build and basic engine usage work end-to-end, but the npm package is not yet published. iOS FFI is in progress and not included in `0.1.0-beta.1`; see [Platforms](#platforms). +NodeDB Lite is in **public beta** as of **v0.1.0 (2026-05-23)**. All engines listed in [`docs/lite-support-matrix.md`](docs/lite-support-matrix.md) are feature-complete and covered by tests. The public surface — the `NodeDb` trait, the supported SQL plan variants, the C FFI ABI, and the WASM / npm bindings — is stable; clients written against 0.1.0 will keep working through 1.0. + +**v0.1.0 — Beta (today).** Use it for embedded workloads and for piloting Lite ↔ Origin sync. The public surface is stable; expect internal changes (redb layout, on-disk index format, sync-protocol internals) between minor releases. Patch and minor bumps will land as needed. + +**v1.0.0 — Production-ready (target: 2026-07-23).** What 1.0 guarantees: + +- **API & SQL stability** — semver from 1.0 onward. No breaking changes to the `NodeDb` trait, the supported SQL plan variants, or the C FFI / WASM ABIs within a major. +- **Sync protocol stability** — the Lite ↔ Origin WebSocket wire frames frozen at the version Origin ships in its 1.0. +- **On-disk format stability** — no breaking migrations within 1.x. Forward-compatible upgrades only. +- **Platform parity** — iOS FFI built and tested against a macOS environment; Android JNI packaging fully gated. +- **Performance SLAs** — published p99 targets per engine, regression-gated in CI. +- **Security audit** — third-party audit completed and findings remediated before 1.0 ships. + +Pre-1.0 versions may change internals between releases — that work is critical-path hardening (persistence layouts, sync coordination, platform packaging) that has to be exercised in real production conditions before we put a stability stamp on it. The public API, SQL surface, and sync wire frames won't break; everything underneath is fair game until 1.0. + +> **Note:** This release track applies to **NodeDB Lite** only. [NodeDB Origin](https://github.com/NodeDB-Lab/nodedb), [`ndb` CLI](https://github.com/NodeDB-Lab/nodedb-cli), and [NodeDB Studio](https://github.com/NodeDB-Lab/nodedb-studio) are versioned independently on their own tracks. ## Why NodeDB Lite - **One embedded engine, not a stitched-together client stack.** Vectors, graph, documents, full-text, timeseries, key-value, and other NodeDB data models run in one runtime with shared storage and one query surface. - **Built for offline-first.** Every write is captured as a CRDT delta locally, then merged to Origin when the network comes back. - **Same API as Origin.** The `NodeDb` trait is identical across Lite and server deployments, so moving from on-device to remote is a connection decision, not an architecture rewrite. -- **Edge-ready.** Linux, macOS, Windows, Android, iOS, and browser/WASM support from the same product line. +- **Edge-ready.** Linux, macOS, Windows, Android, and browser/WASM in `0.1.0`; iOS lands before `1.0`. ## When to Use @@ -74,23 +89,22 @@ NodeDB Lite is in beta as of version `0.1.0-beta.1`.

The wire shape is: - -``` -vector_clock = { "_global": { "": } } -``` - -Origin's `handle_handshake` extracts `last_seen_lsn` as the **maximum value -across all inner maps of all collection keys**: - -```rust -// nodedb/nodedb/src/control/server/sync/session/handshake.rs:75-79 -self.last_seen_lsn = msg - .vector_clock - .values() - .flat_map(|m| m.values().copied()) - .max() - .unwrap_or(0); -``` - -This means Origin does **not** parse collection or document identifiers from the -clock; it only extracts the scalar high-water mark. The `_global` key is -treated identically to any real collection name — Origin takes the max counter -from its inner map. - -**Consequence**: Lite's global-clock encoding is accepted by Origin and resume -semantics are preserved for the beta release. Origin will replay deltas whose -LSN is greater than `last_seen_lsn`. - -### Future (post-beta) - -A per-collection/per-document clock would allow Origin to resume at finer -granularity and skip replay of already-seen collections. This is a known -improvement area and is not part of the 0.1.0-beta.1 contract. - -### Divergence from field comment - -The `HandshakeMsg.vector_clock` field has a doc comment that says -`"{ collection: { doc_id: lamport_ts } }"`. Lite sends `{ "_global": { peer_hex: counter } }`. -The mismatch is intentional at the implementation level (Origin only takes the -max), but the comment is misleading. The comment should be updated to reflect -that Origin only uses the scalar maximum and that the `_global` encoding is -the accepted Lite contract. This is tracked as a documentation gap, not a bug. - ---- - -## Fork Detection - -Fork detection activates when **both** `lite_id` is non-empty **and** `epoch > 0`. - -| Scenario | Origin response | -|---------------------------------------------------|-----------------------------------------------------| -| `lite_id` empty or `epoch == 0` | Fork detection skipped; session proceeds normally | -| New `lite_id` (never seen before) | Epoch stored; session proceeds normally | -| Same `lite_id`, `epoch > last_seen_epoch` | Epoch updated; session proceeds normally | -| Same `lite_id`, `epoch == last_seen_epoch` | `fork_detected: true`, `success: false` | -| Same `lite_id`, `epoch < last_seen_epoch` | `fork_detected: true`, `success: false` | -| Same `lite_id`, same epoch, clean reconnect | Treated as fork if `epoch_tracker` still holds the same value — Lite must bump epoch on reconnect after write | - -Source: `nodedb/nodedb/src/control/server/sync/session/handshake.rs:173-214`. - -**Important nuance**: the epoch tracker is in-memory (`Mutex>`). -A server restart clears the tracker, so a client reconnecting after an Origin -restart with the same `lite_id` + `epoch` will **not** trigger fork detection -on that reconnect. This is the expected behaviour for the beta. - ---- - -## Resume Semantics - -After a successful handshake, Origin sets `last_seen_lsn` to the maximum -counter from the client's `vector_clock` and uses it as the replay start point. -Deltas with LSN `> last_seen_lsn` are sent to the client; deltas at or below -that mark are skipped. - -Lite's global-clock encoding means the resume point is the **highest counter -Lite has seen across all peers**, not per-collection. This may cause minor -redundant replay in multi-collection scenarios but will never cause a gap. - ---- - -## Trust Mode - -An empty `jwt_token` bypasses JWT validation. Origin creates an identity with -`user_id = 0`, `tenant_id = 0`, role `ReadWrite`. This mode is for -development and integration tests only. Production deployments must provide -a valid JWT. - -Source: `nodedb/nodedb/src/control/server/sync/session/handshake.rs:54-103`. - ---- - -## CollectionPurged (0x14) — Out of Scope for 0.1.0-beta.1 - -### Origin side (wired) - -Origin's event plane broadcasts a `CollectionPurgedMsg` (frame type `0x14`) to -every connected Lite session that has subscribed or pushed deltas to the -affected collection. The broadcast path is: - -1. `DROP COLLECTION` DDL → `catalog_entry/post_apply/async_dispatch/collection.rs` -2. → `crdt_sync/delivery.rs::broadcast_collection_purged()` -3. → encodes `CollectionPurgedMsg { collection, purge_lsn }` and enqueues into - each matching session's control channel. - -`SyncSession::track_collection()` records the `(tenant_id, collection)` pair -on every `DeltaPush` and `ShapeSubscribe` so the broadcast filter is correct. - -### Lite side (not handled for beta) - -Lite's `dispatch_frame` in `sync/transport.rs` does **not** match on -`SyncMessageType::CollectionPurged` (0x14). The frame falls through to the -`_ =>` arm and is logged as "unexpected frame type from Origin". No shape -eviction, no local collection purge, no application notification occurs. - -### Why not tested in 0.1.0-beta.1 - -- Triggering the broadcast requires issuing a `DROP COLLECTION` DDL against - Origin, which requires a pgwire or HTTP control connection. The interop test - harness exposes only the sync WebSocket on port 9090. -- Asserting Lite's current behavior (silent log) would couple tests to log - output rather than observable state. - -### When to promote to in-scope - -When Lite's `dispatch_frame` handles `CollectionPurged` by evicting the -subscribed shape's local state and notifying the application layer, and when -the test harness exposes a pgwire/HTTP endpoint so tests can issue -`DROP COLLECTION` to trigger the broadcast end-to-end. - ---- - -## Definition Sync (PREVIEW) - -Definition sync carries function, trigger, and procedure definitions from -Origin to connected Lite clients via `DefinitionSync` (frame opcode `0x70`, -`SyncMessageType::DefinitionSync`). - -### Lite side (receive path) - -Lite's `dispatch_frame` in `nodedb-lite/nodedb-lite/src/sync/transport.rs` -matches on `SyncMessageType::DefinitionSync` and calls -`delegate.import_definition(&msg)`. `import_definition` is implemented in -`nodedb-lite/nodedb-lite/src/nodedb/sync_delegate.rs` and handles both `"put"` -(create/replace) and `"delete"` (drop) actions. The wire type -`DefinitionSyncMsg` is defined in -`nodedb/nodedb-types/src/sync/wire/timeseries.rs` with opcode registered at -`nodedb/nodedb-types/src/sync/wire/frame.rs`. - -### Origin side (emission path) - -Origin emits `DefinitionSync` (0x70) frames after every WAL-durable DDL -commit that affects executable definitions: - -- `CREATE [OR REPLACE] FUNCTION` / `DROP FUNCTION` — handled by - `control/server/pgwire/ddl/function/create/handler.rs` and `drop.rs` -- `CREATE [OR REPLACE] TRIGGER` / `DROP TRIGGER` — handled by - `control/server/pgwire/ddl/trigger/create.rs` and `drop.rs` -- `CREATE [OR REPLACE] PROCEDURE` / `DROP PROCEDURE` — handled by - `control/server/pgwire/ddl/procedure/create/handler.rs` and `drop.rs` - -Broadcast is coordinated through `DefinitionSyncFanout` -(`control/server/sync/definition_fanout.rs`), a per-session bounded mpsc -registry that mirrors the `ArrayDeliveryRegistry` pattern. The fanout is held -on `SharedState` and registered per session from `session_handler.rs` after -handshake. The session handler uses `tokio::select!` to await either an -inbound WebSocket message or a new frame on the definition-sync channel, so -server-push delivery is not gated on client traffic. - -### Tests - -`nodedb-lite/nodedb-lite/tests/definition_sync_interop.rs` contains four -real-transport tests against a live `OriginServer`: - -- `definition_sync_function_put` — CREATE OR REPLACE FUNCTION → `"put"` frame -- `definition_sync_function_delete` — DROP FUNCTION → `"delete"` frame -- `definition_sync_trigger_put` — CREATE OR REPLACE TRIGGER → `"put"` frame -- `definition_sync_procedure_put` — CREATE OR REPLACE PROCEDURE → `"put"` frame - -All four pass (4/4) in the `heavy` nextest group. - ---- - -## Array Sync (BETA) - -Array sync uses a dedicated wire sub-protocol layered on top of the standard -sync session.

VectorState gains codec_sidecars and per_index_config maps so each collection can carry an independent quantization sidecar. ensure_hnsw is promoted to a free function and gains a VectorStorageDtype argument; callers in batch insert and vector trait impl now look up the per-collection dtype before creating a new index. On insert the sidecar is lazily installed and the vector is encoded in-place; on delete the sidecar slot is tombstoned and the sidecar is persisted so restarts do not re-surface deleted entries. Encode/persist failures degrade gracefully to FP32 rerank rather than aborting the write. --- nodedb-lite/src/engine/vector/mod.rs | 1 + .../src/engine/vector/sidecar/install.rs | 483 ++++++++++++++++++ nodedb-lite/src/engine/vector/sidecar/mod.rs | 6 + .../src/engine/vector/sidecar/persist.rs | 269 ++++++++++ nodedb-lite/src/engine/vector/state.rs | 83 +++ nodedb-lite/src/nodedb/batch.rs | 12 +- nodedb-lite/src/nodedb/trait_impl/vector.rs | 96 +++- 7 files changed, 944 insertions(+), 6 deletions(-) create mode 100644 nodedb-lite/src/engine/vector/sidecar/install.rs create mode 100644 nodedb-lite/src/engine/vector/sidecar/mod.rs create mode 100644 nodedb-lite/src/engine/vector/sidecar/persist.rs diff --git a/nodedb-lite/src/engine/vector/mod.rs b/nodedb-lite/src/engine/vector/mod.rs index c6ce906..f5353a4 100644 --- a/nodedb-lite/src/engine/vector/mod.rs +++ b/nodedb-lite/src/engine/vector/mod.rs @@ -9,5 +9,6 @@ pub use nodedb_vector::hnsw::search as hnsw_search; pub use nodedb_vector::{DistanceMetric, HnswIndex, HnswParams, SearchResult}; pub mod search; +pub mod sidecar; pub mod state; pub use state::VectorState; diff --git a/nodedb-lite/src/engine/vector/sidecar/install.rs b/nodedb-lite/src/engine/vector/sidecar/install.rs new file mode 100644 index 0000000..5dcf212 --- /dev/null +++ b/nodedb-lite/src/engine/vector/sidecar/install.rs @@ -0,0 +1,483 @@ +// SPDX-License-Identifier: Apache-2.0 + +//!

The physical visitor adapter delegates to these modules, removing the inline search implementation that was previously embedded in adapter.rs. Unsupported ArrayOp variants (Project, Aggregate, Elementwise, Compact) are converted from unimplemented! panics to proper LiteError::Unsupported returns, giving callers a recoverable error instead of a process abort. unsupported.rs gains the missing _storage_dtype parameter on the vector primary write stub to match the updated visitor trait signature. --- nodedb-lite/src/query/engine.rs | 1 + .../src/query/physical_visitor/adapter.rs | 124 +---- nodedb-lite/src/query/physical_visitor/mod.rs | 2 + .../src/query/physical_visitor/text_op.rs | 2 - .../src/query/physical_visitor/vector_op.rs | 429 ++++++++++++++++++ .../query/physical_visitor/vector_write.rs | 395 ++++++++++++++++ nodedb-lite/src/query/visitor/adapter.rs | 2 +- nodedb-lite/src/query/visitor/unsupported.rs | 1 + 8 files changed, 852 insertions(+), 104 deletions(-) create mode 100644 nodedb-lite/src/query/physical_visitor/vector_op.rs create mode 100644 nodedb-lite/src/query/physical_visitor/vector_write.rs diff --git a/nodedb-lite/src/query/engine.rs b/nodedb-lite/src/query/engine.rs index 25ad924..cd5e23e 100644 --- a/nodedb-lite/src/query/engine.rs +++ b/nodedb-lite/src/query/engine.rs @@ -35,6 +35,7 @@ pub struct LiteQueryEngine { } impl LiteQueryEngine { + #[allow(clippy::too_many_arguments)] pub fn new( crdt: Arc>, strict: Arc>, diff --git a/nodedb-lite/src/query/physical_visitor/adapter.rs b/nodedb-lite/src/query/physical_visitor/adapter.rs index 5db3cde..418e493 100644 --- a/nodedb-lite/src/query/physical_visitor/adapter.rs +++ b/nodedb-lite/src/query/physical_visitor/adapter.rs @@ -15,13 +15,13 @@ use nodedb_physical::PhysicalTaskVisitor;

charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce four focused op-family modules under src/query/ — document_ops, kv_ops, crdt_ops, and meta_ops — each broken into sub-files by concern (reads, writes, indexes, etc.). Add value_utils for shared JSON/Loro conversion helpers used across the handlers. Wires the new modules into query/mod.rs so the rest of the crate can resolve them. --- nodedb-lite/src/query/crdt_ops/list.rs | 81 ++ nodedb-lite/src/query/crdt_ops/mod.rs | 5 + nodedb-lite/src/query/crdt_ops/read.rs | 50 + nodedb-lite/src/query/crdt_ops/version.rs | 156 ++++ nodedb-lite/src/query/crdt_ops/write.rs | 61 ++ nodedb-lite/src/query/document_ops/indexes.rs | 147 +++ nodedb-lite/src/query/document_ops/mod.rs | 17 + nodedb-lite/src/query/document_ops/reads.rs | 400 ++++++++ nodedb-lite/src/query/document_ops/sets.rs | 92 ++ nodedb-lite/src/query/document_ops/writes.rs | 446 +++++++++ nodedb-lite/src/query/kv_ops/indexes.rs | 160 ++++ nodedb-lite/src/query/kv_ops/mod.rs | 5 + nodedb-lite/src/query/kv_ops/reads.rs | 303 +++++++ nodedb-lite/src/query/kv_ops/sorted.rs | 396 ++++++++ nodedb-lite/src/query/kv_ops/writes.rs | 855 ++++++++++++++++++ nodedb-lite/src/query/meta_ops/array.rs | 66 ++ .../src/query/meta_ops/continuous_agg.rs | 249 +++++ nodedb-lite/src/query/meta_ops/distributed.rs | 62 ++ nodedb-lite/src/query/meta_ops/indexes.rs | 45 + nodedb-lite/src/query/meta_ops/info.rs | 52 ++ nodedb-lite/src/query/meta_ops/lifecycle.rs | 175 ++++ nodedb-lite/src/query/meta_ops/mod.rs | 30 + nodedb-lite/src/query/meta_ops/synonyms.rs | 99 ++ nodedb-lite/src/query/meta_ops/temporal.rs | 135 +++ nodedb-lite/src/query/mod.rs | 5 + nodedb-lite/src/query/value_utils.rs | 44 + 26 files changed, 4136 insertions(+) create mode 100644 nodedb-lite/src/query/crdt_ops/list.rs create mode 100644 nodedb-lite/src/query/crdt_ops/mod.rs create mode 100644 nodedb-lite/src/query/crdt_ops/read.rs create mode 100644 nodedb-lite/src/query/crdt_ops/version.rs create mode 100644 nodedb-lite/src/query/crdt_ops/write.rs create mode 100644 nodedb-lite/src/query/document_ops/indexes.rs create mode 100644 nodedb-lite/src/query/document_ops/mod.rs create mode 100644 nodedb-lite/src/query/document_ops/reads.rs create mode 100644 nodedb-lite/src/query/document_ops/sets.rs create mode 100644 nodedb-lite/src/query/document_ops/writes.rs create mode 100644 nodedb-lite/src/query/kv_ops/indexes.rs create mode 100644 nodedb-lite/src/query/kv_ops/mod.rs create mode 100644 nodedb-lite/src/query/kv_ops/reads.rs create mode 100644 nodedb-lite/src/query/kv_ops/sorted.rs create mode 100644 nodedb-lite/src/query/kv_ops/writes.rs create mode 100644 nodedb-lite/src/query/meta_ops/array.rs create mode 100644 nodedb-lite/src/query/meta_ops/continuous_agg.rs create mode 100644 nodedb-lite/src/query/meta_ops/distributed.rs create mode 100644 nodedb-lite/src/query/meta_ops/indexes.rs create mode 100644 nodedb-lite/src/query/meta_ops/info.rs create mode 100644 nodedb-lite/src/query/meta_ops/lifecycle.rs create mode 100644 nodedb-lite/src/query/meta_ops/mod.rs create mode 100644 nodedb-lite/src/query/meta_ops/synonyms.rs create mode 100644 nodedb-lite/src/query/meta_ops/temporal.rs create mode 100644 nodedb-lite/src/query/value_utils.rs diff --git a/nodedb-lite/src/query/crdt_ops/list.rs b/nodedb-lite/src/query/crdt_ops/list.rs new file mode 100644 index 0000000..859738b --- /dev/null +++ b/nodedb-lite/src/query/crdt_ops/list.rs @@ -0,0 +1,81 @@ +// SPDX-License-Identifier: Apache-2.0 +//!

The unsupported-stub macro is updated to reflect the narrower set of still-unimplemented variants now that document, kv, crdt, and meta are handled. Each dispatch module calls into the corresponding *_ops handler, keeping the visitor impl free of business logic. --- .../src/query/physical_visitor/adapter.rs | 387 ----------------- .../query/physical_visitor/adapter/array.rs | 305 +++++++++++++ .../query/physical_visitor/adapter/crdt.rs | 157 +++++++ .../physical_visitor/adapter/document.rs | 285 +++++++++++++ .../src/query/physical_visitor/adapter/kv.rs | 399 ++++++++++++++++++ .../query/physical_visitor/adapter/meta.rs | 242 +++++++++++ .../src/query/physical_visitor/adapter/mod.rs | 109 +++++ .../src/query/physical_visitor/unsupported.rs | 33 +- 8 files changed, 1500 insertions(+), 417 deletions(-) delete mode 100644 nodedb-lite/src/query/physical_visitor/adapter.rs create mode 100644 nodedb-lite/src/query/physical_visitor/adapter/array.rs create mode 100644 nodedb-lite/src/query/physical_visitor/adapter/crdt.rs create mode 100644 nodedb-lite/src/query/physical_visitor/adapter/document.rs create mode 100644 nodedb-lite/src/query/physical_visitor/adapter/kv.rs create mode 100644 nodedb-lite/src/query/physical_visitor/adapter/meta.rs create mode 100644 nodedb-lite/src/query/physical_visitor/adapter/mod.rs diff --git a/nodedb-lite/src/query/physical_visitor/adapter.rs b/nodedb-lite/src/query/physical_visitor/adapter.rs deleted file mode 100644 index 5cf5a6e..0000000 --- a/nodedb-lite/src/query/physical_visitor/adapter.rs +++ /dev/null @@ -1,387 +0,0 @@ -// SPDX-License-Identifier: Apache-2.0 -//! `PhysicalTaskVisitor` impl for Lite.

When set, fully-compacted segments are retained as tombstones with a fully_deleted_at_ms timestamp rather than being immediately removed, preserving the audit trail for temporal purge. purge_bitemporal_before(collection, cutoff_ms) clears tombstoned segment entries whose fully_deleted_at_ms is older than the cutoff and persists the updated metadata. Row count, scan, and compaction paths all skip tombstoned entries. Non-bitemporal collections behave identically to before. --- nodedb-lite/src/engine/columnar/store.rs | 143 ++++++++++++++++++++++- nodedb-lite/src/query/ddl/columnar.rs | 9 +- nodedb-lite/src/query/ddl/convert.rs | 2 +- nodedb-lite/src/query/ddl/htap.rs | 2 +- nodedb-lite/src/query/ddl/timeseries.rs | 2 +- 5 files changed, 149 insertions(+), 9 deletions(-) diff --git a/nodedb-lite/src/engine/columnar/store.rs b/nodedb-lite/src/engine/columnar/store.rs index f982062..a0b5300 100644 --- a/nodedb-lite/src/engine/columnar/store.rs +++ b/nodedb-lite/src/engine/columnar/store.rs @@ -23,6 +23,7 @@ use nodedb_types::Namespace; use nodedb_types::columnar::{ColumnarProfile, ColumnarSchema}; use nodedb_types::value::Value; +use crate::engine::array::ops::util::time::now_ms; use crate::error::LiteError; use crate::storage::engine::{StorageEngine, WriteOp}; #[cfg(not(target_arch = "wasm32"))] @@ -47,13 +48,27 @@ const META_COLUMNAR_COLLECTIONS: &[u8] = b"meta:columnar_collections"; struct SegmentMeta { segment_id: u32, row_count: u64, + /// Milliseconds since Unix epoch when this segment was first written. + /// Used by bitemporal purge to determine which superseded segments are + /// eligible for deletion. + #[serde(default)] + system_time_from_ms: i64, + /// For bitemporal collections: the millisecond timestamp when the last + /// live row in this segment was deleted (compacted away). `None` means + /// the segment still has live rows.

Merge implements full SQL MERGE semantics — WHEN MATCHED UPDATE/DELETE and WHEN NOT MATCHED INSERT — evaluated against a join map built from the source collection. MaterializeScan provides cursor-paginated collection export for the clone materializer. The response is msgpack-framed as [next_cursor, [[doc_id, surrogate, value_bytes], ...]] and works for both schemaless (CRDT) and strict document collections. All three ops were previously returning Unsupported errors. --- nodedb-lite/src/query/document_ops/sets.rs | 557 ++++++++++++++++++++- 1 file changed, 556 insertions(+), 1 deletion(-) diff --git a/nodedb-lite/src/query/document_ops/sets.rs b/nodedb-lite/src/query/document_ops/sets.rs index 08b610e..b1eac47 100644 --- a/nodedb-lite/src/query/document_ops/sets.rs +++ b/nodedb-lite/src/query/document_ops/sets.rs @@ -3,17 +3,23 @@ use std::collections::HashMap; +use nodedb_physical::physical_plan::document::merge_types::{ + MergeActionOp, MergeClauseKind, MergeClauseOp, +}; use nodedb_types::result::QueryResult; use nodedb_types::value::Value; use crate::error::LiteError; use crate::query::engine::LiteQueryEngine; +use crate::query::msgpack_helpers::{write_array_header, write_bin, write_str, write_u32}; use crate::query::value_utils::value_to_string; use crate::storage::engine::{StorageEngine, StorageEngineSync}; use super::is_strict; use super::reads::loro_value_to_ndb_value; -use super::writes::batch_insert; +use super::writes::{batch_insert, point_delete, point_insert, point_update}; + +type UpdateValue = nodedb_physical::physical_plan::document::types::UpdateValue; /// InsertSelect: copy documents from source to target collection. /// @@ -90,3 +96,552 @@ pub async fn insert_select( batch_insert(engine, target_collection, &documents).await } + +/// MaterializeScan: cursor-paginated full collection scan for the clone materializer. +/// +/// Lite is single-node — there is no distributed cursor executor.

The adapter/columnar.rs dispatch module covers Scan, Insert, Delete, and aggregate ops, delegating to the columnar engine and returning structured QueryResult values. The unsupported macro no longer includes a columnar stub. --- nodedb-lite/src/query/columnar_ops/mod.rs | 3 + nodedb-lite/src/query/columnar_ops/reads.rs | 369 ++++++++++ nodedb-lite/src/query/columnar_ops/writes.rs | 655 ++++++++++++++++++ nodedb-lite/src/query/mod.rs | 2 + .../physical_visitor/adapter/columnar.rs | 129 ++++ .../src/query/physical_visitor/adapter/mod.rs | 9 +- .../src/query/physical_visitor/unsupported.rs | 7 - 7 files changed, 1166 insertions(+), 8 deletions(-) create mode 100644 nodedb-lite/src/query/columnar_ops/mod.rs create mode 100644 nodedb-lite/src/query/columnar_ops/reads.rs create mode 100644 nodedb-lite/src/query/columnar_ops/writes.rs create mode 100644 nodedb-lite/src/query/physical_visitor/adapter/columnar.rs diff --git a/nodedb-lite/src/query/columnar_ops/mod.rs b/nodedb-lite/src/query/columnar_ops/mod.rs new file mode 100644 index 0000000..9631710 --- /dev/null +++ b/nodedb-lite/src/query/columnar_ops/mod.rs @@ -0,0 +1,3 @@ +// SPDX-License-Identifier: Apache-2.0 +pub mod reads; +pub mod writes; diff --git a/nodedb-lite/src/query/columnar_ops/reads.rs b/nodedb-lite/src/query/columnar_ops/reads.rs new file mode 100644 index 0000000..fc338a3 --- /dev/null +++ b/nodedb-lite/src/query/columnar_ops/reads.rs @@ -0,0 +1,369 @@ +// SPDX-License-Identifier: Apache-2.0 +//!

Temporal purge handlers (handle_temporal_purge_document_strict, handle_temporal_purge_columnar, handle_temporal_purge_edge_store) are converted from Unsupported returns to full implementations backed by the new history modules. Tests covering bitemporal purge for strict and columnar engines are added in temporal.rs. --- nodedb-lite/src/query/engine.rs | 3 + nodedb-lite/src/query/meta_ops/distributed.rs | 62 ---- .../src/query/meta_ops/distributed/cancel.rs | 100 ++++++ .../src/query/meta_ops/distributed/mod.rs | 14 + .../src/query/meta_ops/distributed/raw.rs | 42 +++ .../src/query/meta_ops/distributed/tenant.rs | 310 ++++++++++++++++ .../src/query/meta_ops/distributed/txn.rs | 114 ++++++ .../src/query/meta_ops/distributed/wal.rs | 110 ++++++ nodedb-lite/src/query/meta_ops/mod.rs | 6 +- nodedb-lite/src/query/meta_ops/temporal.rs | 336 ++++++++++++++++-- .../src/query/physical_visitor/adapter/kv.rs | 27 +- .../query/physical_visitor/adapter/meta.rs | 78 +++- 12 files changed, 1085 insertions(+), 117 deletions(-) delete mode 100644 nodedb-lite/src/query/meta_ops/distributed.rs create mode 100644 nodedb-lite/src/query/meta_ops/distributed/cancel.rs create mode 100644 nodedb-lite/src/query/meta_ops/distributed/mod.rs create mode 100644 nodedb-lite/src/query/meta_ops/distributed/raw.rs create mode 100644 nodedb-lite/src/query/meta_ops/distributed/tenant.rs create mode 100644 nodedb-lite/src/query/meta_ops/distributed/txn.rs create mode 100644 nodedb-lite/src/query/meta_ops/distributed/wal.rs diff --git a/nodedb-lite/src/query/engine.rs b/nodedb-lite/src/query/engine.rs index cd5e23e..c0277d8 100644 --- a/nodedb-lite/src/query/engine.rs +++ b/nodedb-lite/src/query/engine.rs @@ -19,6 +19,7 @@ use crate::error::LiteError; use crate::storage::engine::{StorageEngine, StorageEngineSync}; use super::catalog::LiteCatalog; +use super::meta_ops::CancellationRegistry; /// Lite-side query engine. pub struct LiteQueryEngine { @@ -32,6 +33,7 @@ pub struct LiteQueryEngine { pub(crate) vector_state: Arc>, pub(crate) array_state: Arc>, pub(crate) fts_state: Arc, + pub(crate) cancellation: CancellationRegistry, } impl LiteQueryEngine { @@ -57,6 +59,7 @@ impl LiteQueryEngine { vector_state, array_state, fts_state, + cancellation: CancellationRegistry::new(), } } diff --git a/nodedb-lite/src/query/meta_ops/distributed.rs b/nodedb-lite/src/query/meta_ops/distributed.rs deleted file mode 100644 index d02d0f5..0000000 --- a/nodedb-lite/src/query/meta_ops/distributed.rs +++ /dev/null @@ -1,62 +0,0 @@ -// SPDX-License-Identifier: Apache-2.0 -//!

`timeseries_ops`: time-range scan, retention, aggregation, gap-fill, and continuous aggregate handlers - `query_ops`: sub-query, join, lateral, set-op, and recursive plan execution handlers shared by the visitor layer --- nodedb-lite/src/query/graph_ops/algorithms.rs | 716 ++++++++++++++++++ nodedb-lite/src/query/graph_ops/edges.rs | 278 +++++++ nodedb-lite/src/query/graph_ops/fusion.rs | 396 ++++++++++ nodedb-lite/src/query/graph_ops/labels.rs | 112 +++ .../src/query/graph_ops/match_engine/ast.rs | 143 ++++ .../query/graph_ops/match_engine/dispatch.rs | 442 +++++++++++ .../query/graph_ops/match_engine/executor.rs | 319 ++++++++ .../src/query/graph_ops/match_engine/mod.rs | 14 + .../graph_ops/match_engine/predicates.rs | 202 +++++ nodedb-lite/src/query/graph_ops/mod.rs | 9 + nodedb-lite/src/query/graph_ops/stats.rs | 179 +++++ nodedb-lite/src/query/graph_ops/temporal.rs | 222 ++++++ nodedb-lite/src/query/graph_ops/traversal.rs | 281 +++++++ nodedb-lite/src/query/mod.rs | 4 + nodedb-lite/src/query/query_ops/aggregate.rs | 456 +++++++++++ nodedb-lite/src/query/query_ops/facets.rs | 202 +++++ .../src/query/query_ops/joins/broadcast.rs | 83 ++ .../src/query/query_ops/joins/common.rs | 257 +++++++ nodedb-lite/src/query/query_ops/joins/hash.rs | 187 +++++ .../src/query/query_ops/joins/inline_hash.rs | 56 ++ nodedb-lite/src/query/query_ops/joins/mod.rs | 8 + .../src/query/query_ops/joins/nested_loop.rs | 141 ++++ .../src/query/query_ops/joins/shuffle.rs | 85 +++ .../src/query/query_ops/joins/sort_merge.rs | 223 ++++++ .../src/query/query_ops/lateral_loop.rs | 236 ++++++ .../src/query/query_ops/lateral_top_k.rs | 299 ++++++++ nodedb-lite/src/query/query_ops/mod.rs | 8 + .../src/query/query_ops/recursive_scan.rs | 213 ++++++ .../src/query/query_ops/recursive_value.rs | 210 +++++ nodedb-lite/src/query/spatial_ops/mod.rs | 3 + nodedb-lite/src/query/spatial_ops/reads.rs | 236 ++++++ nodedb-lite/src/query/spatial_ops/writes.rs | 95 +++ nodedb-lite/src/query/timeseries_ops/mod.rs | 3 + nodedb-lite/src/query/timeseries_ops/reads.rs | 337 +++++++++ .../src/query/timeseries_ops/writes.rs | 385 ++++++++++ 35 files changed, 7040 insertions(+) create mode 100644 nodedb-lite/src/query/graph_ops/algorithms.rs create mode 100644 nodedb-lite/src/query/graph_ops/edges.rs create mode 100644 nodedb-lite/src/query/graph_ops/fusion.rs create mode 100644 nodedb-lite/src/query/graph_ops/labels.rs create mode 100644 nodedb-lite/src/query/graph_ops/match_engine/ast.rs create mode 100644 nodedb-lite/src/query/graph_ops/match_engine/dispatch.rs create mode 100644 nodedb-lite/src/query/graph_ops/match_engine/executor.rs create mode 100644 nodedb-lite/src/query/graph_ops/match_engine/mod.rs create mode 100644 nodedb-lite/src/query/graph_ops/match_engine/predicates.rs create mode 100644 nodedb-lite/src/query/graph_ops/mod.rs create mode 100644 nodedb-lite/src/query/graph_ops/stats.rs create mode 100644 nodedb-lite/src/query/graph_ops/temporal.rs create mode 100644 nodedb-lite/src/query/graph_ops/traversal.rs create mode 100644 nodedb-lite/src/query/query_ops/aggregate.rs create mode 100644 nodedb-lite/src/query/query_ops/facets.rs create mode 100644 nodedb-lite/src/query/query_ops/joins/broadcast.rs create mode 100644 nodedb-lite/src/query/query_ops/joins/common.rs create mode 100644 nodedb-lite/src/query/query_ops/joins/hash.rs create mode 100644 nodedb-lite/src/query/query_ops/joins/inline_hash.rs create mode 100644 nodedb-lite/src/query/query_ops/joins/mod.rs create mode 100644 nodedb-lite/src/query/query_ops/joins/nested_loop.rs create mode 100644 nodedb-lite/src/query/query_ops/joins/shuffle.rs create mode 100644 nodedb-lite/src/query/query_ops/joins/sort_merge.rs create mode 100644 nodedb-lite/src/query/query_ops/lateral_loop.rs create mode 100644 nodedb-lite/src/query/query_ops/lateral_top_k.rs create mode 100644 nodedb-lite/src/query/query_ops/mod.rs create mode 100644 nodedb-lite/src/query/query_ops/recursive_scan.rs create mode 100644 nodedb-lite/src/query/query_ops/recursive_value.rs create mode 100644 nodedb-lite/src/query/spatial_ops/mod.rs create mode 100644 nodedb-lite/src/query/spatial_ops/reads.rs create mode 100644 nodedb-lite/src/query/spatial_ops/writes.rs create mode 100644 nodedb-lite/src/query/timeseries_ops/mod.rs create mode 100644 nodedb-lite/src/query/timeseries_ops/reads.rs create mode 100644 nodedb-lite/src/query/timeseries_ops/writes.rs diff --git a/nodedb-lite/src/query/graph_ops/algorithms.rs b/nodedb-lite/src/query/graph_ops/algorithms.rs new file mode 100644 index 0000000..be1f7f4 --- /dev/null +++ b/nodedb-lite/src/query/graph_ops/algorithms.rs @@ -0,0 +1,716 @@ +// SPDX-License-Identifier: Apache-2.0 + +//!

The new type carries two fields: - `meta`: primitive `MetadataFilter` conditions (equality, range, in-list, IS NULL) that can be serialized and pushed to the physical visitor for pre-filtering. - `exprs`: complex `QExpr` predicates (functions, arithmetic, CAST, CASE) that are evaluated row-by-row at post-scan time. Previously, any `FilterExpr::Expr` in a WHERE clause caused an `Unsupported` error. Now primitive and complex predicates coexist: the primitive portion is pushed down as before, while complex predicates fall through to `apply_scan_post_processing` for row-level evaluation. All visitor call-sites (vector search, text search, lateral, queries, recursive, scan_post, search, timeseries) are updated to access `.meta` for the physical pre-filter bytes. --- nodedb-lite/src/query/filter_convert.rs | 454 ++++++++++++++++-- .../src/query/visitor/adapter/text_search.rs | 10 +- .../query/visitor/adapter/vector_search.rs | 5 +- nodedb-lite/src/query/visitor/lateral.rs | 4 +- nodedb-lite/src/query/visitor/queries.rs | 33 +- nodedb-lite/src/query/visitor/recursive.rs | 5 +- nodedb-lite/src/query/visitor/scan_post.rs | 25 +- nodedb-lite/src/query/visitor/search.rs | 4 +- nodedb-lite/src/query/visitor/timeseries.rs | 4 +- 9 files changed, 475 insertions(+), 69 deletions(-) diff --git a/nodedb-lite/src/query/filter_convert.rs b/nodedb-lite/src/query/filter_convert.rs index 0ad4f20..94c8200 100644 --- a/nodedb-lite/src/query/filter_convert.rs +++ b/nodedb-lite/src/query/filter_convert.rs @@ -1,11 +1,16 @@ // SPDX-License-Identifier: Apache-2.0 -//!

RedbStorage remains for WASM pending OPFS wiring; the redb dep is retained until a subsequent cleanup pass. Drop StorageEngineSync entirely. pagedb is async-only and block_on is not viable in a WASM/OPFS environment, so the sync surface has no forward path. All callers across nodedb-lite, nodedb-lite-ffi, and nodedb-lite-wasm convert to the async StorageEngine trait. scan_range and scan_range_bounded become async trait methods. State held across await points moves from std::sync::Mutex to tokio::sync::Mutex. RedbOpLog retains a localized block_in_place adapter to satisfy the external OpLog trait bound on native-only paths. FFI bridges call through the runtime handle. Add PagedbStorage at src/storage/pagedb_storage.rs and switch native FFI, integration tests, and examples from RedbStorage to PagedbStorage. Various correctness issues surfaced and were fixed during validation: missing awaits on formerly-sync calls, MutexGuard not Send across await boundaries, an incorrect open API call in PagedbStorage, array sync tests converted to multi_thread flavor, and a WHERE predicate bug in document-schemaless scan_post that made fields invisible by treating the document column as opaque JSON rather than expanding its fields into the filter context. 686/686 non-environmental tests pass after the migration. --- Cargo.toml | 12 +- nodedb-lite-ffi/include/nodedb_lite.h | 3 +

Segment writes use an 8-byte length-prefix envelope inside the wire path to recover exact byte counts past page padding; the bytes the engines see remain bit-identical to the on-disk formats they always wrote. Cold-load paths probe the segment first and fall back to the legacy KV blob when none is present, so existing data continues to open cleanly.

WASM builds now use the encrypted page-store backend through its OPFS VFS, with a pure-JS worker for the browser side. Substrate: - Delete `RedbStorage` impl, its tests, and the `redb` workspace dependency - Drop redb error variants from `LiteError`; pagedb error mapping is the sole storage-error surface Naming cleanup (KV-store-backed, no substrate in the name): - `RedbOpLog` → `KvOpLogStore` - `op_log_redb.rs` → `op_log_store.rs` - `redb_key` / `split_redb_key` → `kv_key` / `split_kv_key` - `RedbEntry` / `to_redb_entries` → `KvFlushEntry` / `to_kv_entries` - 35+ doc comments rewritten WASM: - Replace the hand-rolled `OpfsBackend` (redb `StorageBackend` over `FileSystemSyncAccessHandle`) with `PagedbStorage` - Drop `redb`, `nodedb-array`, and the OPFS-specific `web-sys` features from `nodedb-lite-wasm` - `openPersistent(filename, peerId, workerUrl)` now requires a worker URL (the JS worker is shipped by the page-store crate as a const) Lite test suite: 709 / 709 non-network tests passing on native. WASM compile: `cargo check -p nodedb-lite-wasm --target wasm32-unknown-unknown` is green. Migration is substrate-complete; zero `redb` references remain in source, tests, or Cargo.toml. --- Cargo.toml | 1 - nodedb-lite-wasm/Cargo.toml | 20 +- nodedb-lite-wasm/src/array.rs | 54 +- nodedb-lite-wasm/src/lib.rs | 434 +++++---- nodedb-lite-wasm/src/opfs_backend.rs | 121 --- nodedb-lite-wasm/tests/smoke.rs | 37 + nodedb-lite/Cargo.toml | 8 +- nodedb-lite/src/config.rs | 2 +- nodedb-lite/src/engine/array/manifest.rs | 2 +- nodedb-lite/src/engine/array/segments.rs | 2 +- nodedb-lite/src/engine/crdt/engine.rs | 4 +- nodedb-lite/src/engine/fts/checkpoint.rs | 4 +- nodedb-lite/src/engine/fts/manager.rs | 3 +- nodedb-lite/src/engine/fts/mod.rs | 2 +- nodedb-lite/src/engine/graph/mod.rs | 2 +- nodedb-lite/src/engine/htap/bridge.rs | 2 +- nodedb-lite/src/engine/spatial/checkpoint.rs | 4 +- nodedb-lite/src/engine/strict/engine.rs | 2 +- nodedb-lite/src/engine/strict/schema.rs | 2 +- .../engine/timeseries/engine/compaction.rs | 8 +- .../src/engine/timeseries/engine/core.rs | 2 +- .../src/engine/timeseries/engine/flush.rs | 14 +- .../src/engine/timeseries/engine/lifecycle.rs | 12 +- .../src/engine/timeseries/engine/mod.rs | 6 +- .../src/engine/timeseries/engine/sync.rs | 2 +- .../src/engine/timeseries/engine/wal.rs | 2 +- nodedb-lite/src/engine/timeseries/identity.rs | 6 +- .../src/engine/timeseries/query_routing.rs | 2 +- .../src/engine/vector/sidecar/persist.rs | 4 +- nodedb-lite/src/error.rs | 38 +- nodedb-lite/src/lib.rs | 3 +- nodedb-lite/src/nodedb/collection/ddl.rs | 4 +- nodedb-lite/src/nodedb/collection/kv.rs | 53 +- nodedb-lite/src/nodedb/core/flush.rs | 2 +- nodedb-lite/src/nodedb/core/open.rs | 4 +- nodedb-lite/src/nodedb/core/types.rs | 2 +- nodedb-lite/src/nodedb/definitions.rs | 2 +- nodedb-lite/src/nodedb/diagnostic.rs | 2 +- nodedb-lite/src/nodedb/health.rs | 4 +- nodedb-lite/src/query/kv_ops/indexes.rs | 4 +- nodedb-lite/src/query/kv_ops/reads.rs | 22 +- nodedb-lite/src/query/kv_ops/writes.rs | 38 +- .../src/query/meta_ops/distributed/tenant.rs | 2 +- .../src/query/meta_ops/distributed/wal.rs | 6 +- nodedb-lite/src/query/meta_ops/info.rs | 2 +- nodedb-lite/src/query/meta_ops/synonyms.rs | 2 +- .../query/physical_visitor/adapter/graph.rs | 4 + .../src/query/physical_visitor/adapter/mod.rs | 7 + .../src/query/visitor/adapter/visitor.rs | 6 + nodedb-lite/src/sequence.rs | 2 +- nodedb-lite/src/storage/checksum.rs | 4 +- nodedb-lite/src/storage/engine.rs | 30 +- nodedb-lite/src/storage/mod.rs | 1 - nodedb-lite/src/storage/pagedb_storage.rs | 78 +- nodedb-lite/src/storage/redb_storage.rs | 882 ------------------ nodedb-lite/src/sync/array/inbound/apply.rs | 6 +- .../src/sync/array/inbound/dispatcher.rs | 6 +- .../src/sync/array/inbound/fixtures.rs | 4 +- nodedb-lite/src/sync/array/mod.rs | 6 +- .../array/{op_log_redb.rs => op_log_store.rs} | 20 +- nodedb-lite/src/sync/array/outbound.rs | 12 +- nodedb-lite/src/sync/mod.rs | 2 +- nodedb-lite/src/sync/outbound/columnar.rs | 2 +- nodedb-lite/src/sync/transport/delegate.rs | 2 +- nodedb-lite/tests/common/harness.rs | 6 +- nodedb-lite/tests/concurrency.rs | 2 +- nodedb-lite/tests/crash_recovery.rs | 2 +- nodedb-lite/tests/kv_engine_gate.rs | 6 +- nodedb-lite/tests/sync_interop_columnar.rs | 2 +- nodedb-lite/tests/sync_interop_fts.rs | 2 +- nodedb-lite/tests/sync_interop_spatial.rs | 2 +- nodedb-lite/tests/sync_interop_timeseries.rs | 2 +- nodedb-lite/tests/sync_interop_vector.rs | 2 +- 73 files changed, 613 insertions(+), 1441 deletions(-) delete mode 100644 nodedb-lite-wasm/src/opfs_backend.rs create mode 100644 nodedb-lite-wasm/tests/smoke.rs delete mode 100644 nodedb-lite/src/storage/redb_storage.rs rename nodedb-lite/src/sync/array/{op_log_redb.rs => op_log_store.rs} (96%) diff --git a/Cargo.toml b/Cargo.toml index ddcec26..4402cb9 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -46,7 +46,6 @@ sonic-rs = "0.5" zerompk = { version = "0.5", features = ["std", "derive"] } # Storage -redb = "2" pagedb = { version = "0", default-features = false } roaring = "0.11" arrow = { version = "58", default-features = false, features = ["ipc"] } diff --git a/nodedb-lite-wasm/Cargo.toml b/nodedb-lite-wasm/Cargo.toml index 0008644..abf628e 100644 --- a/nodedb-lite-wasm/Cargo.toml +++ b/nodedb-lite-wasm/Cargo.toml @@ -12,6 +12,13 @@ homepage.workspace = true [lib] crate-type = ["cdylib", "rlib"] +[features] +# Enable the pagedb OPFS VFS and the persistent-storage JS API. +# This is the default for browser builds — disable only when testing in Node.js +# environments that do not provide the Web Worker API. +default = ["opfs"] +opfs = ["pagedb/opfs"] + [dependencies] nodedb-lite = { workspace = true } nodedb-types = { workspace = true } @@ -23,18 +30,13 @@ serde = { workspace = true } serde_json = { workspace = true } sonic-rs = { workspace = true } wasm-bindgen-futures = "0.4" +# pagedb is a direct dep here so we can export `run_opfs_worker` which calls +# into pagedb's OpfsWorker registrar.

Three independent optimizations stacked: - Bounded LRU read cache in front of the storage layer. Caches the raw encoded value (TTL deadline intact so expiry is re-checked on every hit) and is invalidated on every write/delete. Capacity configurable via `LiteConfig::kv_cache_capacity` (default 10,000 entries, ≈ 800 KB at typical payload sizes). - Lock-free fast path on `kv_get` when the write buffer overlay is empty. `kv_overlay_len: AtomicUsize` mirrors the overlay size under Release/Acquire ordering; the single-writer design makes this safe without locking on the common read-only path. - `KeyBuf` stack-allocates the composite namespace key when it fits in 64 bytes (typical for KV keys), avoiding the per-call heap allocation on hot reads. Write-side cost is small and bounded: an atomic store and a cache pop per write. Bench: kv_set 1.5 µs → 1.7 µs; kv_get (miss) unchanged at ~11 µs; kv_get (hit) 11.5 µs → 165 ns. 714 / 714 non-network tests pass. --- Cargo.toml | 1 + nodedb-lite/Cargo.toml | 1 + nodedb-lite/src/config.rs | 14 ++ nodedb-lite/src/nodedb/collection/kv.rs | 239 +++++++++++++++++++--- nodedb-lite/src/nodedb/core/open.rs | 13 +- nodedb-lite/src/nodedb/core/types.rs | 15 ++ nodedb-lite/src/storage/pagedb_storage.rs | 42 +++- 7 files changed, 286 insertions(+), 39 deletions(-) diff --git a/Cargo.toml b/Cargo.toml index 4402cb9..d0d38d1 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -48,6 +48,7 @@ zerompk = { version = "0.5", features = ["std", "derive"] } # Storage pagedb = { version = "0", default-features = false } roaring = "0.11" +lru = "0.12" arrow = { version = "58", default-features = false, features = ["ipc"] } crc32c = "0.6" diff --git a/nodedb-lite/Cargo.toml b/nodedb-lite/Cargo.toml index 737fd10..2b0a4b4 100644 --- a/nodedb-lite/Cargo.toml +++ b/nodedb-lite/Cargo.toml @@ -23,6 +23,7 @@ nodedb-graph = { workspace = true } nodedb-vector = { workspace = true } nodedb-fts = { workspace = true } roaring = { workspace = true } +lru = { workspace = true } nodedb-strict = { workspace = true } nodedb-columnar = { workspace = true } nodedb-array = { workspace = true } diff --git a/nodedb-lite/src/config.rs b/nodedb-lite/src/config.rs index 54f3f91..9d98fec 100644 --- a/nodedb-lite/src/config.rs +++ b/nodedb-lite/src/config.rs @@ -72,6 +72,19 @@ pub struct LiteConfig { /// Argon2id parallelism lanes.

For recommendation and entity-centric queries, the caller knows which nodes matter — PPR lets them express that as a seed weight map. When `AlgoParams::personalization_vector` is set, the teleport distribution is built from the map (normalized to sum=1.0; nodes absent from the map start at 0.0). Initial rank is seeded from the same distribution. When the map sums to near-zero the engine falls back to uniform to avoid division by zero. When the field is absent, behavior is identical to before. Three tests cover: seed concentration, empty-map fallback to uniform, and round-trip stability of the unnormalized input. --- nodedb-lite/src/query/graph_ops/algorithms.rs | 147 +++++++++++++++++- 1 file changed, 145 insertions(+), 2 deletions(-) diff --git a/nodedb-lite/src/query/graph_ops/algorithms.rs b/nodedb-lite/src/query/graph_ops/algorithms.rs index be1f7f4..eae58c3 100644 --- a/nodedb-lite/src/query/graph_ops/algorithms.rs +++ b/nodedb-lite/src/query/graph_ops/algorithms.rs @@ -65,11 +65,41 @@ fn pagerank(csr: &CsrIndex, params: &AlgoParams) -> Vec> { let max_iter = params.iterations(20); let tol = params.convergence_tolerance(); - let mut rank = vec![1.0f64 / n as f64; n]; + // Threshold below which a personalization vector sum is treated as zero → uniform fallback. + const UNIFORM_FALLBACK_THRESHOLD: f64 = 1e-12; + + // Build the teleport (personalization) distribution. + // For standard PageRank (no personalization) this is uniform 1/n. + // For PPR this is normalized per the caller-supplied map; nodes absent from the + // map receive 0.0.

Add a versioned key-value history layer under `engine/document/history/` that encodes each document version as: key: `{collection}:{doc_id}\0{system_from_ms:020}` value: `[tag:u8][valid_from:i64 LE][valid_until:i64 LE][body]` Tag bytes mirror Origin's format (0x00 LIVE, 0xFF TOMBSTONE, 0xFE GDPR_ERASED) so cross-node comparisons need no translation. Collections marked `WITH (bitemporal=true)` in DDL are flagged via `CollectionMeta::is_bitemporal()`. The document trait implementation branches on that flag: bitemporal collections use the new history module for both reads and writes; non-bitemporal collections continue through the existing CRDT path unchanged. The two new trait methods (`document_get_as_of`, `document_put_with_valid_time`) are wired through dispatch. 13 integration tests cover the storage format and the public API. --- .../src/engine/document/history/key.rs | 128 ++++++++ .../src/engine/document/history/mod.rs | 23 ++ .../src/engine/document/history/ops.rs | 234 ++++++++++++++ .../src/engine/document/history/value.rs | 156 ++++++++++ nodedb-lite/src/engine/document/mod.rs | 11 + nodedb-lite/src/engine/mod.rs | 1 + nodedb-lite/src/nodedb/trait_impl/dispatch.rs | 22 ++ nodedb-lite/src/nodedb/trait_impl/document.rs | 241 +++++++++++++-- nodedb-lite/src/query/ddl/document.rs | 64 ++++ nodedb-lite/src/query/ddl/mod.rs | 12 + nodedb-lite/tests/document_bitemporal_api.rs | 290 ++++++++++++++++++ .../tests/document_bitemporal_storage.rs | 185 +++++++++++ 12 files changed, 1346 insertions(+), 21 deletions(-) create mode 100644 nodedb-lite/src/engine/document/history/key.rs create mode 100644 nodedb-lite/src/engine/document/history/mod.rs create mode 100644 nodedb-lite/src/engine/document/history/ops.rs create mode 100644 nodedb-lite/src/engine/document/history/value.rs create mode 100644 nodedb-lite/src/engine/document/mod.rs create mode 100644 nodedb-lite/src/query/ddl/document.rs create mode 100644 nodedb-lite/tests/document_bitemporal_api.rs create mode 100644 nodedb-lite/tests/document_bitemporal_storage.rs diff --git a/nodedb-lite/src/engine/document/history/key.rs b/nodedb-lite/src/engine/document/history/key.rs new file mode 100644 index 0000000..7d9cd67 --- /dev/null +++ b/nodedb-lite/src/engine/document/history/key.rs @@ -0,0 +1,128 @@ +// SPDX-License-Identifier: Apache-2.0 + +//!

charset=UTF-8 Content-Transfer-Encoding: 8bit Wires the graph_pagerank trait method through to the CSR engine. Standard PageRank uses uniform initial ranks; Personalized PageRank biases toward caller-supplied seed nodes (values are normalized before the power iteration). Empty collections return an empty Vec rather than an error — a graph with no edges has no ranks to report, which is not a failure condition. Five integration tests cover: standard convergence, personalized bias, damping override, empty-graph short-circuit, and the iteration cap. --- nodedb-lite/src/nodedb/trait_impl/dispatch.rs | 11 ++ nodedb-lite/src/nodedb/trait_impl/graph.rs | 59 ++++++ nodedb-lite/tests/graph_pagerank_api.rs | 168 ++++++++++++++++++ 3 files changed, 238 insertions(+) create mode 100644 nodedb-lite/tests/graph_pagerank_api.rs diff --git a/nodedb-lite/src/nodedb/trait_impl/dispatch.rs b/nodedb-lite/src/nodedb/trait_impl/dispatch.rs index da3a503..3c880ee 100644 --- a/nodedb-lite/src/nodedb/trait_impl/dispatch.rs +++ b/nodedb-lite/src/nodedb/trait_impl/dispatch.rs @@ -136,6 +136,17 @@ impl NodeDb for NodeDbLite { self.graph_stats_impl(collection, as_of).await } + async fn graph_pagerank( + &self, + collection: &str, + personalization: Option>, + damping: Option, + max_iterations: Option, + ) -> NodeDbResult> { + self.graph_pagerank_impl(collection, personalization, damping, max_iterations) + .await + } + async fn graph_shortest_path( &self, collection: &str, diff --git a/nodedb-lite/src/nodedb/trait_impl/graph.rs b/nodedb-lite/src/nodedb/trait_impl/graph.rs index 188f6f1..7862c25 100644 --- a/nodedb-lite/src/nodedb/trait_impl/graph.rs +++ b/nodedb-lite/src/nodedb/trait_impl/graph.rs @@ -14,6 +14,8 @@ use nodedb_types::id::{EdgeId, NodeId}; use nodedb_types::result::{SubGraph, SubGraphEdge, SubGraphNode}; use nodedb_types::value::Value; +use nodedb_graph::params::{AlgoParams, GraphAlgorithm}; + use crate::engine::array::ops::util::time::now_ms; use crate::engine::graph::history; use crate::engine::graph::index::{CsrIndex, Direction}; @@ -21,6 +23,7 @@ use crate::engine::graph::traversal::DEFAULT_MAX_VISITED; use crate::nodedb::LockExt; use crate::nodedb::NodeDbLite; use crate::nodedb::convert::{loro_value_to_document, value_to_loro}; +use crate::query::graph_ops::algorithms; use crate::storage::engine::StorageEngine; /// Returns the CRDT collection name for edges belonging to a graph collection. @@ -316,6 +319,62 @@ impl NodeDbLite { }]) } + /// Run PageRank (or Personalized PageRank) on the collection's CSR graph. + /// + /// Returns an empty `Vec` when the collection has no edges rather than an + /// error — an empty graph simply has no ranks to report. + pub(super) async fn graph_pagerank_impl( + &self, + collection: &str, + personalization: Option>, + damping: Option, + max_iterations: Option, + ) -> NodeDbResult> { + // Fast path: if the collection isn't in the CSR map it has no edges. + { + let csr_map = self.csr.lock_or_recover(); + if !csr_map.contains_key(collection) { + return Ok(Vec::new()); + } + } + + let params = AlgoParams { + collection: collection.to_string(), + damping, + max_iterations: max_iterations.map(|v| v as usize), + personalization_vector: personalization, + ..Default::default() + }; + + let result = algorithms::run_algo(&self.csr, GraphAlgorithm::PageRank, ¶ms) + .map_err(|e| NodeDbError::storage(format!("graph_pagerank: {e}")))?; + + // `result.columns` == ["node_id", "rank"]; extract and sort descending. + let mut pairs: Vec<(String, f64)> = result + .rows + .into_iter() + .filter_map(|mut row| { + if row.len() < 2 { + return None; + } + let rank = match row.pop() { + Some(Value::Float(f)) => f, + _ => return None, + }; + let node_id = match row.pop() { + Some(Value::String(s)) => s, + _ => return None, + }; + Some((node_id, rank)) + }) + .collect(); + + pairs.sort_unstable_by(|(_, a), (_, b)| { + b.partial_cmp(a).unwrap_or(std::cmp::Ordering::Equal) + }); + Ok(pairs) + } + /// Unweighted BFS shortest path from `from` to `to` within `collection`, /// bounded by `max_depth`.

Graph tombstone sentinel mismatch: record_edge_delete was checking u64::MAX while record_edge_insert wrote i64::MAX as u64, making delete tombstones a silent no-op. Introduce SYSTEM_TO_CURRENT constant and use it consistently. Vector id_map was never written to the checkpoint, so vector_search returned raw HNSW integer strings instead of document IDs after restart. flush.rs now writes the id_map blob alongside the HNSW checkpoint; open.rs restores it.

charset=UTF-8 Content-Transfer-Encoding: 8bit CREATE COLLECTION now calls `CrdtEngine::register_collection` immediately so the SQL catalog can resolve the collection name for SELECT even before any document has been inserted. On open, the registration set is rebuilt by scanning the `document_bitemporal:` prefix in the Meta namespace so the fix survives process restart. `execute_scan` for schemaless-document collections checks the bitemporal flag and, when set, reads live state directly from DocumentHistory rather than the Loro in-memory snapshot (which is only updated on explicit flush). `scan_live_documents` in `history::ops` provides the authoritative live-ID set by walking the history prefix and filtering to the latest non-tombstoned version per document. Test `select_after_create` covers the cold-start path: CREATE COLLECTION, INSERT, SELECT — all without an intervening flush. --- nodedb-lite/src/engine/crdt/engine.rs | 31 ++++- .../src/engine/document/history/ops.rs | 65 ++++++++++- nodedb-lite/src/nodedb/core/open.rs | 22 ++++ nodedb-lite/src/query/ddl/document.rs | 8 ++ nodedb-lite/src/query/engine.rs | 67 +++++++++++ nodedb-lite/tests/select_after_create.rs | 110 ++++++++++++++++++ 6 files changed, 300 insertions(+), 3 deletions(-) create mode 100644 nodedb-lite/tests/select_after_create.rs diff --git a/nodedb-lite/src/engine/crdt/engine.rs b/nodedb-lite/src/engine/crdt/engine.rs index 483eb00..8d57d1d 100644 --- a/nodedb-lite/src/engine/crdt/engine.rs +++ b/nodedb-lite/src/engine/crdt/engine.rs @@ -49,6 +49,11 @@ pub struct CrdtEngine { /// Conflict resolution policies per collection. /// Evaluated on sync when Origin rejects a delta. pub(super) policies: nodedb_crdt::PolicyRegistry, + /// Explicitly registered collection names for collections that exist in the + /// catalog (e.g. bitemporal document collections) but have no Loro root-map + /// entry yet (i.e. no document has been inserted).

All call sites now use the platform-independent `crate::runtime::now_millis()` (u64) and the new `now_millis_i64()` (i64) helper, which works on native and WASM without `SystemTime` / `UNIX_EPOCH` import repetition. Also fixes the `#[allow(clippy::await_holding_lock)]` suppression in `kv_put_with_deadline` by scoping the mutex guard so it is dropped before the await point. --- nodedb-lite/src/engine/array/engine.rs | 9 +- nodedb-lite/src/engine/array/ops/util/mod.rs | 1 - nodedb-lite/src/engine/array/ops/util/time.rs | 13 - nodedb-lite/src/engine/htap/bridge.rs | 18 +- nodedb-lite/src/event.rs | 11 +- nodedb-lite/src/nodedb/collection/kv.rs | 231 ++++++++++-------- nodedb-lite/src/query/value_utils.rs | 12 - nodedb-lite/src/runtime.rs | 9 + 8 files changed, 141 insertions(+), 163 deletions(-) delete mode 100644 nodedb-lite/src/engine/array/ops/util/time.rs diff --git a/nodedb-lite/src/engine/array/engine.rs b/nodedb-lite/src/engine/array/engine.rs index dfb2360..f2ad22e 100644 --- a/nodedb-lite/src/engine/array/engine.rs +++ b/nodedb-lite/src/engine/array/engine.rs @@ -442,7 +442,7 @@ impl ArrayEngineState { // Retention compaction (only if configured). if let Some(retain_ms) = state.audit_retain_ms { - let now_ms = now_millis(); + let now_ms = crate::runtime::now_millis_i64(); crate::engine::array::retention::run_retention( storage, name, @@ -461,13 +461,6 @@ impl ArrayEngineState { // ── Helpers ─────────────────────────────────────────────────────────────────── -fn now_millis() -> i64 { - std::time::SystemTime::now() - .duration_since(std::time::UNIX_EPOCH) - .unwrap_or_default() - .as_millis() as i64 -} - async fn cell_versions_from_segments( storage: &Arc, name: &str, diff --git a/nodedb-lite/src/engine/array/ops/util/mod.rs b/nodedb-lite/src/engine/array/ops/util/mod.rs index 8a037d3..db838f4 100644 --- a/nodedb-lite/src/engine/array/ops/util/mod.rs +++ b/nodedb-lite/src/engine/array/ops/util/mod.rs @@ -3,4 +3,3 @@ //!

On open, `NodeDbLite` now runs `backfill_latest_version` for every bitemporal collection found in Meta storage. The backfill is idempotent (safe on fresh databases) and logs a warning rather than failing open if it errors, so databases written before the index was introduced continue to work via the prefix-scan fallback. --- .../src/engine/document/history/key.rs | 9 + .../src/engine/document/history/ops.rs | 297 -------------- .../engine/document/history/ops/backfill.rs | 260 ++++++++++++ .../src/engine/document/history/ops/flags.rs | 66 +++ .../src/engine/document/history/ops/mod.rs | 21 + .../src/engine/document/history/ops/read.rs | 386 ++++++++++++++++++ .../src/engine/document/history/ops/write.rs | 85 ++++ nodedb-lite/src/engine/document/mod.rs | 4 +- nodedb-lite/src/nodedb/core/open.rs | 41 +- 9 files changed, 857 insertions(+), 312 deletions(-) delete mode 100644 nodedb-lite/src/engine/document/history/ops.rs create mode 100644 nodedb-lite/src/engine/document/history/ops/backfill.rs create mode 100644 nodedb-lite/src/engine/document/history/ops/flags.rs create mode 100644 nodedb-lite/src/engine/document/history/ops/mod.rs create mode 100644 nodedb-lite/src/engine/document/history/ops/read.rs create mode 100644 nodedb-lite/src/engine/document/history/ops/write.rs diff --git a/nodedb-lite/src/engine/document/history/key.rs b/nodedb-lite/src/engine/document/history/key.rs index 7d9cd67..9716acd 100644 --- a/nodedb-lite/src/engine/document/history/key.rs +++ b/nodedb-lite/src/engine/document/history/key.rs @@ -73,6 +73,15 @@ pub fn coll_prefix_end(collection: &str) -> Vec { format!("{collection};").into_bytes() } +/// Build the key for the `LatestVersion` pointer for `(collection, doc_id)`. +/// +/// Layout: `{collection}:{doc_id}` — no NUL separator, no timestamp suffix. +/// The value stored under this key is the `system_from_ms` decimal string of +/// the currently-live `DocumentHistory` row. +pub fn latest_version_key(collection: &str, doc_id: &str) -> Vec { + format!("{collection}:{doc_id}").into_bytes() +} + /// Extract `system_from_ms` from a versioned key byte slice. /// /// Returns `None` if the key has no NUL separator or if the timestamp diff --git a/nodedb-lite/src/engine/document/history/ops.rs b/nodedb-lite/src/engine/document/history/ops.rs deleted file mode 100644 index b56486b..0000000 --- a/nodedb-lite/src/engine/document/history/ops.rs +++ /dev/null @@ -1,297 +0,0 @@ -// SPDX-License-Identifier: Apache-2.0 - -//!

From 12bee3d7d9d4ba7aef3558d271ce4dbf3fb1f7b3 Mon Sep 17 00:00:00 2001 From: Farhan Syah Date: Wed, 10 Jun 2026 22:11:13 +0800 Subject: [PATCH 62/83] feat(sync): add SyncGate trait for per-document local-only control MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce a `SyncGate` trait that hosts can install at startup to decide, per document write, whether that document should be pushed to Origin. Documents the gate rejects are still written to local CRDT state and indexed locally (so local reads, FTS, and vector search work), but are excluded from: - the outbound CRDT delta stream (CrdtEngine::drop_pending) - the FTS sync outbound queue - vector insert sync (wired in the follow-up document_put_with_vector path) API: pub trait SyncGate: Send + Sync { fn should_sync(&self, collection: &str, fields: &HashMap) -> bool; } NodeDbLite::set_sync_gate(gate: Arc) The gate is held in an RwLock (one writer at startup, many readers on every write) and re-exported from the crate root alongside NodeDbLite. Also adds FtsCollectionManager::search_with_allowed (over-fetch 8× then filter by ID set) and threads an `allowed_ids` parameter through run_text_search so the gate can scope FTS results to a local haystack. Includes an integration test (tests/sync_gate.rs) that verifies a `PublicOnlyGate` withholds non-public documents from pending CRDT deltas while keeping them readable locally. --- nodedb-lite/src/engine/crdt/engine.rs | 10 + nodedb-lite/src/engine/fts/manager.rs | 51 +++++ nodedb-lite/src/engine/fts/search.rs | 25 ++- nodedb-lite/src/lib.rs | 2 +- nodedb-lite/src/nodedb/core/ops.rs | 38 +++- nodedb-lite/src/nodedb/core/types.rs | 18 ++ nodedb-lite/src/nodedb/mod.rs | 9 +- nodedb-lite/src/nodedb/trait_impl/document.rs | 181 ++++++++++++++++-- nodedb-lite/tests/sync_gate.rs | 76 ++++++++ 9 files changed, 373 insertions(+), 37 deletions(-) create mode 100644 nodedb-lite/tests/sync_gate.rs diff --git a/nodedb-lite/src/engine/crdt/engine.rs b/nodedb-lite/src/engine/crdt/engine.rs index 8d57d1d..074dd2c 100644 --- a/nodedb-lite/src/engine/crdt/engine.rs +++ b/nodedb-lite/src/engine/crdt/engine.rs @@ -434,6 +434,16 @@ impl CrdtEngine { self.pending_deltas.clear(); } + /// Drop a single pending delta by `mutation_id` without touching CRDT state. + /// + /// Unlike [`reject_delta`](Self::reject_delta), this does **not** delete the + /// document — the row stays in local CRDT state (so local reads/search work); + /// it is simply never pushed to Origin.

For text search the existing search_with_allowed over-fetch path (8× top_k) is used. All call sites updated: FFI (C API, JNI), WASM bindings, and all integration tests. Passing None preserves the prior behavior exactly. New test: vector_search_allowed_ids_filters_to_set verifies that a document outside the allowed set is excluded even when its embedding is identical to the query vector. --- nodedb-lite-ffi/src/ffi_document.rs | 1 + nodedb-lite-ffi/src/ffi_vector.rs | 5 ++- nodedb-lite-ffi/src/jni_bridge/core.rs | 2 +- nodedb-lite-wasm/src/lib.rs | 3 +- nodedb-lite/src/nodedb/trait_impl/dispatch.rs | 20 +++++++++- nodedb-lite/src/nodedb/trait_impl/vector.rs | 19 ++++++++- nodedb-lite/tests/e2e.rs | 2 +- nodedb-lite/tests/eviction.rs | 2 +- nodedb-lite/tests/fts_persistence.rs | 2 + .../tests/fts_persistence_bitemporal.rs | 29 ++++++++++++-- nodedb-lite/tests/integration.rs | 11 +++-- nodedb-lite/tests/vector_engine_gate.rs | 40 +++++++++++++++++-- .../tests/vector_id_map_persistence.rs | 15 +++++-- 13 files changed, 130 insertions(+), 21 deletions(-) diff --git a/nodedb-lite-ffi/src/ffi_document.rs b/nodedb-lite-ffi/src/ffi_document.rs index b8ff564..8977728 100644 --- a/nodedb-lite-ffi/src/ffi_document.rs +++ b/nodedb-lite-ffi/src/ffi_document.rs @@ -156,6 +156,7 @@ pub unsafe extern "C" fn nodedb_text_search( query_str, top_k, nodedb_types::TextSearchParams::default(), + None, )) { Ok(results) => { let json_items: Vec = results diff --git a/nodedb-lite-ffi/src/ffi_vector.rs b/nodedb-lite-ffi/src/ffi_vector.rs index 4a56804..0ae72f0 100644 --- a/nodedb-lite-ffi/src/ffi_vector.rs +++ b/nodedb-lite-ffi/src/ffi_vector.rs @@ -67,7 +67,10 @@ pub unsafe extern "C" fn nodedb_vector_search( } let q = unsafe { std::slice::from_raw_parts(query, dim) }; - match h.rt.block_on(h.db.vector_search(collection, q, k, None)) { + match h + .rt + .block_on(h.db.vector_search(collection, q, k, None, None)) + { Ok(results) => { let json_items: Vec = results .iter() diff --git a/nodedb-lite-ffi/src/jni_bridge/core.rs b/nodedb-lite-ffi/src/jni_bridge/core.rs index c017604..56d2719 100644 --- a/nodedb-lite-ffi/src/jni_bridge/core.rs +++ b/nodedb-lite-ffi/src/jni_bridge/core.rs @@ -132,7 +132,7 @@ pub extern "system" fn Java_com_nodedb_lite_NodeDbLite_nativeVectorSearch( use nodedb_client::NodeDb; let results = match h .rt - .block_on(h.db.vector_search(&collection, &buf, k as usize, None)) + .block_on(h.db.vector_search(&collection, &buf, k as usize, None, None)) { Ok(r) => r, Err(_) => return std::ptr::null_mut(), diff --git a/nodedb-lite-wasm/src/lib.rs b/nodedb-lite-wasm/src/lib.rs index 74c80f5..fa5a052 100644 --- a/nodedb-lite-wasm/src/lib.rs +++ b/nodedb-lite-wasm/src/lib.rs @@ -268,7 +268,7 @@ impl NodeDbLiteWasm { k: usize, ) -> Result { let results = dispatch!(self, db, { - db.vector_search(collection, query, k, None) + db.vector_search(collection, query, k, None, None) .await .map_err(|e| JsError::new(&e.to_string())) })?; @@ -482,6 +482,7 @@ impl NodeDbLiteWasm { query, top_k, nodedb_types::TextSearchParams::default(), + None, ) .await .map_err(|e| JsError::new(&e.to_string())) diff --git a/nodedb-lite/src/nodedb/trait_impl/dispatch.rs b/nodedb-lite/src/nodedb/trait_impl/dispatch.rs index 3c880ee..3caa31d 100644 --- a/nodedb-lite/src/nodedb/trait_impl/dispatch.rs +++ b/nodedb-lite/src/nodedb/trait_impl/dispatch.rs @@ -7,6 +7,8 @@ //!

The task calls `flush()` on each tick, bounding the data-loss window uniformly across all engines (KV buffer, CRDT deltas, HNSW id-map, CSR graph, FTS, spatial). Add `LiteConfig::outbound_queue_cap` (default 100 000) that caps the number of pending entries in each durable outbound sync queue. Writes return `LiteError::Backpressure` when the cap is reached.

Entries survive process restarts and disconnects; the sync transport re-drains them on reconnect while Origin deduplicates via its idempotent-producer gate. Key changes: - Add `DurableOutboundQueue`: generic storage-backed bounded queue with configurable cap. Returns `LiteError::Backpressure` at capacity. - Add `StreamSeqTracker`: per-stream monotonic sequence frontier persisted in `Namespace::Meta`. Tracks `last_assigned` and `last_acked` per stream so frame numbering resumes after restart. - Add `constants::PUSH_DRAIN_LIMIT` (256) to bound each push cycle. - Add `reconcile_outbound_enqueue` helper for uniform backpressure error logging at enqueue sites. - FTS and spatial queues gain a staging buffer that is flushed to durable storage by the periodic flush path, keeping synchronous write paths free of async storage I/O. - All outbound queue types are now generic over `S: StorageEngine`. --- nodedb-lite/src/sync/constants.rs | 5 + nodedb-lite/src/sync/mod.rs | 12 +- nodedb-lite/src/sync/outbound/columnar.rs | 298 +++++++--- .../src/sync/outbound/durable_queue.rs | 288 ++++++++++ nodedb-lite/src/sync/outbound/fts.rs | 540 ++++++++++++++---- nodedb-lite/src/sync/outbound/mod.rs | 4 + nodedb-lite/src/sync/outbound/reconcile.rs | 46 ++ nodedb-lite/src/sync/outbound/spatial.rs | 529 +++++++++++++---- nodedb-lite/src/sync/outbound/timeseries.rs | 278 ++++++--- nodedb-lite/src/sync/outbound/vector.rs | 464 ++++++++++++--- nodedb-lite/src/sync/stream_seq.rs | 311 ++++++++++ 11 files changed, 2300 insertions(+), 475 deletions(-) create mode 100644 nodedb-lite/src/sync/constants.rs create mode 100644 nodedb-lite/src/sync/outbound/durable_queue.rs create mode 100644 nodedb-lite/src/sync/outbound/reconcile.rs create mode 100644 nodedb-lite/src/sync/stream_seq.rs diff --git a/nodedb-lite/src/sync/constants.rs b/nodedb-lite/src/sync/constants.rs new file mode 100644 index 0000000..00d872f --- /dev/null +++ b/nodedb-lite/src/sync/constants.rs @@ -0,0 +1,5 @@ +//!

Idempotent-producer state (producer_id, accepted_epoch) is persisted to storage and reloaded on reconnect. --- nodedb-lite/src/nodedb/sync_delegate.rs | 401 ------------- .../nodedb/sync_delegate/array_handlers.rs | 169 ++++++ .../nodedb/sync_delegate/definition_apply.rs | 50 ++ nodedb-lite/src/nodedb/sync_delegate/mod.rs | 554 ++++++++++++++++++ 4 files changed, 773 insertions(+), 401 deletions(-) delete mode 100644 nodedb-lite/src/nodedb/sync_delegate.rs create mode 100644 nodedb-lite/src/nodedb/sync_delegate/array_handlers.rs create mode 100644 nodedb-lite/src/nodedb/sync_delegate/definition_apply.rs create mode 100644 nodedb-lite/src/nodedb/sync_delegate/mod.rs diff --git a/nodedb-lite/src/nodedb/sync_delegate.rs b/nodedb-lite/src/nodedb/sync_delegate.rs deleted file mode 100644 index f2007f7..0000000 --- a/nodedb-lite/src/nodedb/sync_delegate.rs +++ /dev/null @@ -1,401 +0,0 @@ -//! `SyncDelegate` implementation — bridges the sync transport to NodeDbLite's engines. - -#[cfg(not(target_arch = "wasm32"))] -use crate::storage::engine::StorageEngine;

The push loop halts all outbound frames when fenced and waits for reconnect (which clears the flag). - Add `producer_id` and `accepted_epoch` fields populated from the handshake ack; stamped on every outbound frame for idempotent-producer gating by Origin. - Add per-array-ack coalescing: `pending_array_ack` is now keyed by array name so the highest-HLC ack for each array is retained and multiple arrays can be acked in one push tick. - Add token refresh exponential backoff: `token_last_attempt_ms` and `token_refresh_backoff_ms` (initial 5 s, max 5 min) prevent hammering a failing token provider; `is_refresh_backoff_elapsed` gates each attempt. - Add 30-second timeout on the token provider call so a hung provider cannot block the sync task. - Add `stale_timeouts` counter to `SyncMetrics` and `FlowController::cleanup_stale_and_record` to evict timed-out in-flight entries and increment the metric in one step. --- nodedb-lite/src/sync/client/delta.rs | 14 ++ nodedb-lite/src/sync/client/handshake.rs | 15 +- nodedb-lite/src/sync/client/receive.rs | 141 ++++++++++++++- nodedb-lite/src/sync/client/state.rs | 108 ++++++++++- nodedb-lite/src/sync/client/token.rs | 219 ++++++++++++++++++++++- nodedb-lite/src/sync/flow_control.rs | 73 +++++++- 6 files changed, 552 insertions(+), 18 deletions(-) diff --git a/nodedb-lite/src/sync/client/delta.rs b/nodedb-lite/src/sync/client/delta.rs index e0c3e7d..74bac37 100644 --- a/nodedb-lite/src/sync/client/delta.rs +++ b/nodedb-lite/src/sync/client/delta.rs @@ -34,6 +34,10 @@ impl SyncClient { peer_id: self.peer_id, mutation_id: delta.mutation_id, device_valid_time_ms: Some(device_valid_time_ms), + // producer_id, epoch, and seq are overwritten with real producer/epoch/stable-seq in push_crdt_deltas. + producer_id: 0, + epoch: 0, + seq: 0, }) .collect() } @@ -133,12 +137,14 @@ mod tests { collection: "orders".into(), document_id: "o1".into(), delta_bytes: vec![1, 2, 3], + seq: 0, }, PendingDelta { mutation_id: 2, collection: "users".into(), document_id: "u1".into(), delta_bytes: vec![4, 5, 6], + seq: 0, }, ]; @@ -159,6 +165,8 @@ mod tests { mutation_id: 1, lsn: 42, clock_skew_warning_ms: None, + applied_seq: 0, + status: nodedb_types::sync::wire::AckStatus::Applied, }) .await; @@ -202,6 +210,7 @@ mod tests { collection: "test".into(), document_id: "d1".into(), delta_bytes, + seq: 0, }]; let msgs = client.build_delta_pushes(&pending).await; assert_eq!(msgs[0].checksum, expected_crc); @@ -225,18 +234,21 @@ mod tests { collection: "a".into(), document_id: "d1".into(), delta_bytes: vec![1], + seq: 0, }, PendingDelta { mutation_id: 2, collection: "a".into(), document_id: "d2".into(), delta_bytes: vec![2], + seq: 0, }, PendingDelta { mutation_id: 3, collection: "a".into(), document_id: "d3".into(), delta_bytes: vec![3], + seq: 0, }, ]; @@ -253,6 +265,8 @@ mod tests { mutation_id: 1, lsn: 10, clock_skew_warning_ms: None, + applied_seq: 0, + status: nodedb_types::sync::wire::AckStatus::Applied, }) .await; let msgs = client.build_delta_pushes(&pending).await; diff --git a/nodedb-lite/src/sync/client/handshake.rs b/nodedb-lite/src/sync/client/handshake.rs index b4abc2d..4b891a2 100644 --- a/nodedb-lite/src/sync/client/handshake.rs +++ b/nodedb-lite/src/sync/client/handshake.rs @@ -47,9 +47,18 @@ impl SyncClient { clock.advance(peer_id, counter); } } + drop(clock); + + self.set_producer_id(ack.producer_id).await; + self.set_accepted_epoch(ack.accepted_epoch).await; *self.state.lock().await = SyncState::Connected; - tracing::info!(session = %ack.session_id, "sync handshake accepted"); + tracing::info!( + session = %ack.session_id, + producer_id = ack.producer_id, + accepted_epoch = ack.accepted_epoch, + "sync handshake accepted" + ); true } } @@ -96,6 +105,8 @@ mod tests { error: None, fork_detected: false, server_wire_version: 1, + producer_id: 0, + accepted_epoch: 0, }; assert!(client.handle_handshake_ack(&ack).await); @@ -112,6 +123,8 @@ mod tests { error: Some("invalid token".into()), fork_detected: false, server_wire_version: 1, + producer_id: 0, + accepted_epoch: 0, }; assert!(!client.handle_handshake_ack(&ack).await); diff --git a/nodedb-lite/src/sync/client/receive.rs b/nodedb-lite/src/sync/client/receive.rs index 98661e9..76548e1 100644 --- a/nodedb-lite/src/sync/client/receive.rs +++ b/nodedb-lite/src/sync/client/receive.rs @@ -9,9 +9,27 @@ use super::state::SyncClient; impl SyncClient { /// Process a ShapeSnapshot from Origin. + /// + /// Marks the shape as snapshot-loaded and re-bases the sequence tracker + /// so that gap detection restarts from the snapshot LSN rather than any + /// stale watermark from before the resync.

Halt all push when fenced. Run stale in-flight cleanup with AIMD multiplicative decrease every tick. - `SyncDelegate` trait: all pending/ack methods are now async; add `next_stream_seq`, `set_pending_delta_seq`, `persist_*_seq` for durable seq stamping; add `clear_engine_in_flight`, `load/persist _producer_state`. --- nodedb-lite/src/sync/transport/connect.rs | 28 +- nodedb-lite/src/sync/transport/delegate.rs | 204 ++++++++-- nodedb-lite/src/sync/transport/dispatch.rs | 147 +++---- .../src/sync/transport/dispatch_acks.rs | 370 ++++++++++++++++++ nodedb-lite/src/sync/transport/mod.rs | 1 + .../src/sync/transport/push/columnar.rs | 38 +- .../src/sync/transport/push/control.rs | 40 +- nodedb-lite/src/sync/transport/push/fts.rs | 52 ++- nodedb-lite/src/sync/transport/push/mod.rs | 28 ++ .../src/sync/transport/push/spatial.rs | 58 ++- .../src/sync/transport/push/timeseries.rs | 38 +- nodedb-lite/src/sync/transport/push/vector.rs | 68 +++- nodedb-lite/src/sync/transport/tests.rs | 126 ++++-- 13 files changed, 999 insertions(+), 199 deletions(-) create mode 100644 nodedb-lite/src/sync/transport/dispatch_acks.rs diff --git a/nodedb-lite/src/sync/transport/connect.rs b/nodedb-lite/src/sync/transport/connect.rs index f1eee1d..8b477a8 100644 --- a/nodedb-lite/src/sync/transport/connect.rs +++ b/nodedb-lite/src/sync/transport/connect.rs @@ -25,9 +25,29 @@ pub(super) async fn connect_and_run( client: &Arc, delegate: &Arc, ) -> Result<(), LiteError> { - // Reset state for a fresh connection. + // Reload durable producer identity so the outbound path has a valid + // producer_id/accepted_epoch before the handshake is built.

Reject writes with `LiteError::Backpressure` when the memory governor reports `PressureLevel::Critical` in `document_put_impl`, `vector_insert_impl`, `document_put_with_vector_batch_impl`, and the batch vector ingest path. - Wire all outbound enqueue calls through `reconcile_outbound_enqueue` so backpressure errors are uniformly logged and propagated. - FTS and spatial enqueue calls switched from direct durable enqueue to the new staging path (`stage_index`, `stage_delete`, `stage_insert`); the flush task spills staged entries to durable storage periodically. - `NodeDbLite::open_inner` wires `StreamSeqTracker`, loads the Lite identity (`lite_id` + `epoch`) for the handshake, opens all outbound queues with the configured cap, and wires FTS/spatial outbound queues into the query engine for SQL-path writes. - `flush()` now drains the KV write buffer first and spills FTS/spatial staging buffers to durable queues on each flush tick. - Add `LiteError::Backpressure` variant; fix typo in SPDX identifiers. --- nodedb-lite/src/error.rs | 26 ++++ nodedb-lite/src/nodedb/batch.rs | 9 ++ nodedb-lite/src/nodedb/collection/kv.rs | 80 +++++----- nodedb-lite/src/nodedb/core/flush.rs | 30 ++++ nodedb-lite/src/nodedb/core/open.rs | 140 +++++++++++++++--- nodedb-lite/src/nodedb/core/ops.rs | 28 +++- nodedb-lite/src/nodedb/core/types.rs | 65 +++++--- nodedb-lite/src/nodedb/mod.rs | 51 +++++++ nodedb-lite/src/nodedb/trait_impl/document.rs | 23 ++- .../src/nodedb/trait_impl/document_batch.rs | 130 +++++++++------- nodedb-lite/src/nodedb/trait_impl/graph.rs | 9 ++ nodedb-lite/src/nodedb/trait_impl/vector.rs | 46 +++++- nodedb-lite/src/query/columnar_dml.rs | 20 ++- nodedb-lite/src/query/columnar_ops/writes.rs | 25 +++- nodedb-lite/src/query/engine.rs | 37 ++++- nodedb-lite/src/query/meta_ops/temporal.rs | 54 ++++--- .../query/physical_visitor/adapter/array.rs | 16 +- .../physical_visitor/adapter/columnar.rs | 39 ++++- .../query/physical_visitor/adapter/graph.rs | 38 ++++- .../query/physical_visitor/adapter/spatial.rs | 2 + .../physical_visitor/adapter/timeseries.rs | 46 +++++- .../src/query/physical_visitor/text_op.rs | 22 ++- .../src/query/physical_visitor/vector_op.rs | 4 + nodedb-lite/src/query/spatial_ops/writes.rs | 10 ++ .../src/query/timeseries_ops/writes.rs | 64 ++++++-- nodedb-lite/src/query/visitor/array/dml.rs | 2 + nodedb-lite/src/query/visitor/array/query.rs | 12 +- nodedb-lite/src/query/visitor/array/schema.rs | 26 +++- nodedb-lite/src/query/visitor/dml.rs | 18 ++- nodedb-lite/src/query/visitor/timeseries.rs | 17 ++- 30 files changed, 838 insertions(+), 251 deletions(-) diff --git a/nodedb-lite/src/error.rs b/nodedb-lite/src/error.rs index 61c5df0..cf2e119 100644 --- a/nodedb-lite/src/error.rs +++ b/nodedb-lite/src/error.rs @@ -44,6 +44,10 @@ pub enum LiteError { /// failure that cannot be recovered automatically (OPFS has no rename). #[error("OPFS worker bridge failed: {detail}")] WorkerFailed { detail: String }, + + /// An error during key derivation, salt I/O, or encryption setup. + #[error("encryption error: {detail}")] + Encryption { detail: String }, } impl From for LiteError { @@ -80,4 +84,26 @@ mod tests { let ndb: nodedb_types::error::NodeDbError = e.into(); assert!(ndb.to_string().contains("test")); } + + #[test] + fn lite_error_encryption_display_and_convert() { + let e = LiteError::Encryption { + detail: "argon2 key derivation failed".into(), + }; + let rendered = e.to_string(); + assert!(rendered.contains("encryption error")); + assert!(rendered.contains("argon2 key derivation failed")); + + let ndb: nodedb_types::error::NodeDbError = e.into(); + assert!(ndb.to_string().contains("argon2 key derivation failed")); + } + + #[test] + fn lite_error_backpressure_display() { + let e = LiteError::Backpressure { + detail: "outbound queue full".into(), + }; + assert!(e.to_string().contains("backpressure")); + assert!(e.to_string().contains("outbound queue full")); + } } diff --git a/nodedb-lite/src/nodedb/batch.rs b/nodedb-lite/src/nodedb/batch.rs index f76b459..23c9b9f 100644 --- a/nodedb-lite/src/nodedb/batch.rs +++ b/nodedb-lite/src/nodedb/batch.rs @@ -24,6 +24,15 @@ impl NodeDbLite { return Ok(()); } + if self.governor.pressure() == crate::memory::PressureLevel::Critical { + return Err(NodeDbError::storage( + crate::error::LiteError::Backpressure { + detail: "batch vector insert rejected: memory governor is at Critical pressure" + .into(), + }, + )); + } + let dim = vectors[0].1.len(); { diff --git a/nodedb-lite/src/nodedb/collection/kv.rs b/nodedb-lite/src/nodedb/collection/kv.rs index 9f07118..e3919de 100644 --- a/nodedb-lite/src/nodedb/collection/kv.rs +++ b/nodedb-lite/src/nodedb/collection/kv.rs @@ -114,6 +114,14 @@ impl NodeDbLite { value: &[u8], deadline_ms: u64, ) -> NodeDbResult<()> { + if self.governor.pressure() == crate::memory::PressureLevel::Critical { + return Err(nodedb_types::error::NodeDbError::storage( + crate::error::LiteError::Backpressure { + detail: "KV write rejected: memory governor is at Critical pressure".into(), + }, + )); + } + let rkey = kv_key(collection, key.as_bytes()); let encoded = encode_value(deadline_ms, value); @@ -126,10 +134,7 @@ impl NodeDbLite { key: rkey.clone(), value: encoded, }); -

Nextest configuration: - Add `scripts/ensure-origin.sh` setup script that builds the Origin binary before sync-interop and SQL parity test runs. - Wire the setup script into both the `default` and `ci` profiles for all `sync_interop_*`, `sync_load`, `definition_sync_interop`, and `sql_parity` test binaries. Existing integration and sync-interop tests updated throughout to match the new async delegate API, durable outbound queue signatures, and `Encryption` parameter on `PagedbStorage::open`. --- .config/nextest.toml | 15 +++ nodedb-lite/tests/array_sync_catchup.rs | 14 +- nodedb-lite/tests/array_sync_interop.rs | 10 +- nodedb-lite/tests/array_sync_interop_real.rs | 9 ++ nodedb-lite/tests/array_sync_reject.rs | 3 + nodedb-lite/tests/auto_flush.rs | 111 +++++++++++++++ nodedb-lite/tests/common/harness.rs | 3 + nodedb-lite/tests/common/origin.rs | 96 +++++++------ nodedb-lite/tests/crdt_semantics/helpers.rs | 6 + .../tests/crdt_semantics/rejection_paths.rs | 28 +++- nodedb-lite/tests/definition_sync_interop.rs | 20 ++- nodedb-lite/tests/encryption_roundtrip.rs | 75 +++++++++++ nodedb-lite/tests/eviction.rs | 10 +- nodedb-lite/tests/fts_persistence.rs | 8 +- .../tests/fts_persistence_bitemporal.rs | 26 +++- .../tests/graph_persistence_bitemporal.rs | 26 +++- nodedb-lite/tests/integration.rs | 10 +- nodedb-lite/tests/kv_ttl_and_range.rs | 10 +- nodedb-lite/tests/select_after_create.rs | 10 +- nodedb-lite/tests/semantics/clock.rs | 15 ++- nodedb-lite/tests/semantics/compat.rs | 25 +++- nodedb-lite/tests/semantics/dedup.rs | 126 ++++++++++++++++++ nodedb-lite/tests/semantics/fork.rs | 61 ++++++--- nodedb-lite/tests/semantics/mod.rs | 1 + nodedb-lite/tests/spatial_engine_gate.rs | 12 +- nodedb-lite/tests/sql_parity/columnar.rs | 15 ++- nodedb-lite/tests/sql_parity/document.rs | 25 +++- nodedb-lite/tests/sql_parity/strict.rs | 30 ++++- nodedb-lite/tests/sql_parity/timeseries.rs | 15 ++- nodedb-lite/tests/sync_interop_columnar.rs | 10 +- .../tests/sync_interop_compensation.rs | 24 +++- nodedb-lite/tests/sync_interop_delta_ack.rs | 42 +++++- nodedb-lite/tests/sync_interop_fts.rs | 15 ++- nodedb-lite/tests/sync_interop_handshake.rs | 25 +++- nodedb-lite/tests/sync_interop_live.rs | 57 ++++++-- nodedb-lite/tests/sync_interop_reconnect.rs | 28 +++- nodedb-lite/tests/sync_interop_resync.rs | 90 ++++++++++++- nodedb-lite/tests/sync_interop_shape.rs | 15 ++- nodedb-lite/tests/sync_interop_spatial.rs | 15 ++- nodedb-lite/tests/sync_interop_timeseries.rs | 10 +- nodedb-lite/tests/sync_interop_vector.rs | 15 ++- nodedb-lite/tests/sync_load.rs | 8 +- .../tests/vector_id_map_persistence.rs | 18 ++- scripts/ensure-origin.sh | 68 ++++++++++ 44 files changed, 1060 insertions(+), 195 deletions(-) create mode 100644 nodedb-lite/tests/auto_flush.rs create mode 100644 nodedb-lite/tests/encryption_roundtrip.rs create mode 100644 nodedb-lite/tests/semantics/dedup.rs create mode 100755 scripts/ensure-origin.sh diff --git a/.config/nextest.toml b/.config/nextest.toml index 47d5c5b..9d1b709 100644 --- a/.config/nextest.toml +++ b/.config/nextest.toml @@ -5,6 +5,13 @@ # # Run with: cargo nextest run -p nodedb-lite +experimental = ["setup-scripts"] + +[scripts.setup.build-origin] +command = { command-line = "scripts/ensure-origin.sh", relative-to = "workspace-root" } +slow-timeout = { period = "600s", terminate-after = 1 } +capture-stderr = true + [profile.default] # Hard ceiling per test.

WASM (nodedb-lite-wasm): - Update `lib.rs` to use `PagedbStorageMem` and the new `vector_search` signature with `allowed_ids` parameter. - Update WASM README to reflect pagedb backend and new API surface. Docs: - README: update storage backend name from redb to pagedb throughout; update `vector_search` call sites to include the `allowed_ids` argument; add `nodedb-array` and `nodedb-physical` to dev-patch example. - `docs/lite-support-matrix.md`: remove reference to internal protocol notes directory. - `SECURITY.md`: minor copy cleanup. Workspace: - `Cargo.toml`: pin all nodedb-* dependency versions to `0.3`. Examples: - `live_sync.rs`, `load_test.rs`: update to new API signatures. --- Cargo.toml | 28 +- README.md | 33 +- SECURITY.md | 10 +- docs/lite-support-matrix.md | 5 +- nodedb-lite-ffi/include/nodedb_lite.h | 38 +- nodedb-lite-ffi/src/ffi_array.rs | 345 +++++++------ nodedb-lite-ffi/src/ffi_document.rs | 228 +++++---- nodedb-lite-ffi/src/ffi_graph.rs | 246 ++++----- nodedb-lite-ffi/src/ffi_vector.rs | 126 ++--- nodedb-lite-ffi/src/handle_registry.rs | 181 +++++++ nodedb-lite-ffi/src/jni_bridge/array.rs | 453 +++++++++------- nodedb-lite-ffi/src/jni_bridge/core.rs | 568 ++++++++++----------- nodedb-lite-ffi/src/jni_bridge/document.rs | 187 +++++++ nodedb-lite-ffi/src/jni_bridge/mod.rs | 1 + nodedb-lite-ffi/src/lib.rs | 450 ++++++++++------ nodedb-lite-ffi/tests/array_smoke.rs | 8 +- nodedb-lite-ffi/tests/ffi.rs | 10 +- nodedb-lite-wasm/README.md | 8 +- nodedb-lite-wasm/src/lib.rs | 136 +++-- nodedb-lite/examples/live_sync.rs | 15 + nodedb-lite/examples/load_test.rs | 3 + 21 files changed, 1870 insertions(+), 1209 deletions(-) create mode 100644 nodedb-lite-ffi/src/handle_registry.rs create mode 100644 nodedb-lite-ffi/src/jni_bridge/document.rs diff --git a/Cargo.toml b/Cargo.toml index d0d38d1..539c944 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -14,20 +14,20 @@ homepage = "https://nodedb.dev" [workspace.dependencies] # Internal nodedb-lite = { path = "nodedb-lite", version = "0.1.0", default-features = false } -nodedb-types = { version = "*" } -nodedb-client = { version = "*" } -nodedb-codec = { version = "*" } -nodedb-crdt = { version = "*" } -nodedb-query = { version = "*" } -nodedb-spatial = { version = "*" } -nodedb-graph = { version = "*" } -nodedb-vector = { version = "*" } -nodedb-fts = { version = "*" } -nodedb-strict = { version = "*" } -nodedb-columnar = { version = "*" } -nodedb-sql = { version = "*" } -nodedb-array = { version = "*" } -nodedb-physical = { version = "*" } +nodedb-types = { version = "0.3" } +nodedb-client = { version = "0.3" } +nodedb-codec = { version = "0.3" } +nodedb-crdt = { version = "0.3" } +nodedb-query = { version = "0.3" } +nodedb-spatial = { version = "0.3" } +nodedb-graph = { version = "0.3" } +nodedb-vector = { version = "0.3" } +nodedb-fts = { version = "0.3" } +nodedb-strict = { version = "0.3" } +nodedb-columnar = { version = "0.3" } +nodedb-sql = { version = "0.3" } +nodedb-array = { version = "0.3" } +nodedb-physical = { version = "0.3" } # Async tokio = { version = "1" } diff --git a/README.md b/README.md index c8aad0d..475d57b 100644 --- a/README.md +++ b/README.md @@ -51,7 +51,7 @@ NodeDB Lite replaces the usual SQLite + vector sidecar + ad hoc cache + custom s NodeDB Lite is in **public beta** as of **v0.1.0 (2026-05-23)**.

Add an interop test covering lite-to-Origin collection registration end to end, plus a non-panicking query helper for bounded-retry polling while the collection becomes visible. --- .../src/sync/collection_schema_builder.rs | 7 +- nodedb-lite/tests/common/sql.rs | 7 + .../sync_interop_collection_registration.rs | 210 ++++++++++++++++++ 3 files changed, 223 insertions(+), 1 deletion(-) create mode 100644 nodedb-lite/tests/sync_interop_collection_registration.rs diff --git a/nodedb-lite/src/sync/collection_schema_builder.rs b/nodedb-lite/src/sync/collection_schema_builder.rs index 1e9d409..6307b71 100644 --- a/nodedb-lite/src/sync/collection_schema_builder.rs +++ b/nodedb-lite/src/sync/collection_schema_builder.rs @@ -47,8 +47,13 @@ pub(crate) fn descriptor_from_meta(meta: &CollectionMeta) -> Option Result, tokio_postgres::Error> { + self.client.query(sql, &[]).await + } + /// Execute a SQL statement that returns no rows (DDL/DML). pub async fn execute(&self, sql: &str) { self.client.execute(sql, &[]).await.unwrap_or_else(|e| { diff --git a/nodedb-lite/tests/sync_interop_collection_registration.rs b/nodedb-lite/tests/sync_interop_collection_registration.rs new file mode 100644 index 0000000..ff0b08e --- /dev/null +++ b/nodedb-lite/tests/sync_interop_collection_registration.rs @@ -0,0 +1,210 @@ +// SPDX-License-Identifier: Apache-2.0 + +//!
