From 8221a403e6aeef462c9700725e11c908ad40ee90 Mon Sep 17 00:00:00 2001 From: Andrey Kumanyaev Date: Sun, 24 May 2026 00:25:23 +0200 Subject: [PATCH 001/235] feat(graph): extract Store interface from *Graph public surface MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The persistence layer is about to grow a second and third backend (on-disk bbolt + on-disk SQLite), eventually a remote one. To let the rest of gortex stay backend-agnostic, lift the surface the codebase actually consumes out of *Graph into a graph.Store interface and have *Graph satisfy it via a compile-time assertion. The interface mirrors the 28 public methods on *Graph as they exist today, in their current slice-shaped signatures, so this commit is strictly additive: every existing caller keeps working unchanged. A few notes on the shape: - Slice-shaped reads (AllNodes / AllEdges / FindNodesByName / …) materialise their result in memory. Fine for the in-memory store; disk and remote backends will want iterator variants added alongside as those implementations come online — they don't have to replace these. - Memory-estimate methods (RepoMemoryEstimate / AllRepoMemoryEstimates) are inherently in-memory specific. Disk and remote backends return whatever they can compute and callers treat the result as advisory. - *Graph.ResolveMutex() is intentionally NOT on the interface. It's an in-memory implementation detail (resolver coordination) that does not generalise to disk / remote backends. Resolver callers keep operating on *Graph directly until that coordination is reshaped. The compile-time assertion `var _ Store = (*Graph)(nil)` is the load-bearing check: if anyone's edit to *Graph drifts a signature, the build breaks here instead of at runtime when a different backend gets swapped in. No behaviour change, no caller change, no test change. Graph package tests still pass with -race. --- internal/graph/store.go | 87 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 87 insertions(+) create mode 100644 internal/graph/store.go diff --git a/internal/graph/store.go b/internal/graph/store.go new file mode 100644 index 0000000..78f1321 --- /dev/null +++ b/internal/graph/store.go @@ -0,0 +1,87 @@ +package graph + +// Store is the persistence-and-query backend the rest of gortex sees +// behind the *Graph type.

Codifies the union of behaviour the rest of gortex depends on from *graph.Graph today, so new backends (on-disk bbolt, on-disk SQLite, remote) can prove drop-in compatibility before being wired into the daemon. 31 subtests cover: - point lookups (GetNode, GetNodeByQualName) - name + scope queries (FindNodesByName, FindNodesByNameInRepo, GetFileNodes, GetRepoNodes) - edge adjacency (GetOutEdges, GetInEdges) + idempotency + line-disambiguation - bulk reads (AllNodes, AllEdges) + counts + Stats / RepoStats / RepoPrefixes - mutations: AddNode, AddBatch, AddEdge, RemoveEdge, ReindexEdge, SetEdgeProvenance - eviction: EvictFile, EvictRepo (+ "no nodes" edge cases) - structural invariants: EdgeIdentityRevisions, VerifyEdgeIdentities - memory estimation: RepoMemoryEstimate, AllRepoMemoryEstimates - Meta map round-trip - empty-store invariants - concurrent AddNode from 8 goroutines (race-safe) Backends invoke via: storetest.RunConformance(t, func(t *testing.T) graph.Store { return openMyBackend(t) }) memory_conformance_test.go proves the in-memory *graph.Graph passes the full suite — 31/31 subtests green with -race. This is the canonical baseline; on-disk backends will land alongside in follow-up commits and slot into the same harness. A few methods are documented as "permissive" in the suite (EdgeIdentityRevisions allows zero, VerifyEdgeIdentities allows nil, memory-estimate methods only check NodeCount) because they're inherently in-memory-specific. Disk and remote backends return whatever they can compute and callers treat the result as advisory — matches the contract documented on the Store interface itself. --- .../storetest/memory_conformance_test.go | 18 + internal/graph/storetest/storetest.go | 599 ++++++++++++++++++ 2 files changed, 617 insertions(+) create mode 100644 internal/graph/storetest/memory_conformance_test.go create mode 100644 internal/graph/storetest/storetest.go diff --git a/internal/graph/storetest/memory_conformance_test.go b/internal/graph/storetest/memory_conformance_test.go new file mode 100644 index 0000000..2953724 --- /dev/null +++ b/internal/graph/storetest/memory_conformance_test.go @@ -0,0 +1,18 @@ +package storetest_test + +import ( + "testing" + + "github.com/zzet/gortex/internal/graph" + "github.com/zzet/gortex/internal/graph/storetest" +) + +// TestMemoryStoreConformance proves the in-memory *graph.Graph (the +// only Store impl that exists today) satisfies the conformance suite. +// This is the canonical baseline; new backends must pass the same +// battery. +func TestMemoryStoreConformance(t *testing.T) { + storetest.RunConformance(t, func(t *testing.T) graph.Store { + return graph.New() + }) +} diff --git a/internal/graph/storetest/storetest.go b/internal/graph/storetest/storetest.go new file mode 100644 index 0000000..d22640d --- /dev/null +++ b/internal/graph/storetest/storetest.go @@ -0,0 +1,599 @@ +// Package storetest provides a conformance test suite that every +// graph.Store implementation MUST pass.

Embeds bbolt v1.4.3 (already a transitive dep, promoted to direct here), keeps gortex deployable as a single binary, and adds a real on-disk option for any deployment that wants graph state to survive daemon restarts without paying the full snapshot/restore cycle every time. ## Schema Ten top-level bbolt buckets: nodes key=nodeID value=gob(Node) edges key=edgeKeyBytes value=gob(Edge) idx_node_kind key=kind\x00nodeID value=empty idx_node_file key=filePath\x00nodeID value=empty idx_node_repo key=repoPrefix\x00nodeID value=empty idx_node_name key=name\x00nodeID value=empty idx_node_qualname key=qualName value=nodeID idx_edge_out key=fromID\x00edgeKeyBytes value=empty idx_edge_in key=toID\x00edgeKeyBytes value=empty meta misc counters `edgeKeyBytes` encodes (from, to, kind, file, line) with 2-byte big-endian length prefixes on each variable-length component plus a 4-byte big-endian line — uniquely decodable so RemoveEdge / ReindexEdge locate exact rows, lexicographically scannable so adjacency prefix walks are O(k) in the matches. The four scoped node indexes use the standard "{attr}\x00{nodeID} → empty" pattern so a Seek on the attr-prefix enumerates every matching nodeID in O(k). idx_node_qualname is a flat unique lookup (1:1). The `meta` bucket holds the 8-byte big-endian edge-identity-revisions counter, bumped from putEdgeTx and SetEdgeProvenance to mirror the in-memory store's revision semantics. ## Concurrency All writes go through `db.Update` (bbolt single-writer); all reads through `db.View` (unlimited concurrent readers under MVCC). SetEdgeProvenance also takes a small in-memory `provMu` to make its read-modify-write atomic against concurrent provenance bumps. The conformance suite's 8-goroutine concurrent AddNode test passes under `-race`. ## Encoding Node and Edge are gob-encoded — same codec the existing FileStore-based snapshot uses, so Meta map[string]any round-trips without surprises and we inherit gob's forward-compatibility for unknown-field-during-decode (matters when an older daemon reads a newer-schema DB). ## Conformance `storetest.RunConformance` passes 30/30 subtests with `-race`: AddGetNode, AddGetEdge, AddNodeIdempotent, AddEdgeIdempotent, AddEdgeLineDisambiguates, AddBatch, RemoveEdge, EvictFile, EvictFile_NoNodes, EvictRepo, EvictRepo_NoNodes, NodeAndEdgeCount, AllNodesAndEdges, FindNodesByName, FindNodesByNameInRepo, GetFileNodes, GetRepoNodes, GetNodeByQualName, Stats, RepoStats, RepoPrefixes, SetEdgeProvenance, ReindexEdge, Concurrency, EdgeIdentityRevisions, VerifyEdgeIdentities, RepoMemoryEstimate, AllRepoMemoryEstimates, MetaPreserved, EmptyStore. Nothing skipped or weakened — including EdgeIdentityRevisions (real counter persisted in `meta`) and VerifyEdgeIdentities (cross-checks every edge bucket row against both adjacency indexes). ## Dependencies Zero new deps. `go.etcd.io/bbolt v1.4.3` was already an indirect transitive; this commit promotes it to a direct require because the new package imports it. --- go.mod | 2 +- go.sum | 16

Built on modernc.org/sqlite (the transpiled pure-Go SQLite driver) so the single-binary deployment story stays intact — no CGO beyond what tree-sitter already pulls in. Sits behind the same graph.Store interface as the in-memory and bbolt backends and passes the identical conformance suite. Why two on-disk backends: bbolt and SQLite have different sweet spots (bbolt = faster point lookups, simpler model; SQLite = richer query surface, mature tooling). The Store interface lets us ship both and let the deployment pick. Cross-backend benchmarking comes in a follow-up commit. ## Schema Two tables: nodes (PK on id, secondary indexes on name, kind, file_path, partial index on repo_prefix where non-empty, partial UNIQUE on qual_name where non-empty) edges (synthetic INTEGER PK AUTOINCREMENT, UNIQUE(from_id, to_id, kind, file_path, line), secondary indexes on (from_id, kind) and (to_id, kind) for the hot adjacency walks) Meta rides as a gob-encoded BLOB on both tables; NULL when empty so the common case stays zero-cost. The UNIQUE constraint on edges (from, to, kind, file, line) gives INSERT OR IGNORE semantics matching the in-memory store's logical edge-key dedup without needing application-level checks. The two partial indexes (repo_prefix where non-empty, qual_name where non-empty) skip the empty-string default values that the zero-valued Node struct produces, keeping those indexes tight. ## Connection management - DSN PRAGMAs: journal_mode=WAL, synchronous=NORMAL, busy_timeout=5000. - SetMaxOpenConns(1) plus a Go-side write mutex serialises writes and sidesteps SQLITE_BUSY under the 8-goroutine conformance Concurrency test. - All hot queries use prepared *sql.Stmt built once in Open and closed in Close. - AddBatch wraps the inserts in a single BEGIN/COMMIT transaction — the 10-100x speedup that matters at indexing scale. ## EdgeIdentityRevisions / VerifyEdgeIdentities - EdgeIdentityRevisions: in-process atomic.Int64, bumped only when SetEdgeProvenance actually changes the stored origin (mirrors the in-memory store, where the counter is also per-process). - VerifyEdgeIdentities: returns nil. The in-memory invariant is "same *Edge pointer in both adjacency views"; the SQL store has one row per edge so the invariant is structurally trivial. ## Conformance `storetest.RunConformance` passes 30/30 subtests with `-race`. Total: 93 tests across all three backends (in-memory + bolt + sqlite) green. ## Dependencies One new direct dep: `modernc.org/sqlite v1.50.1` (latest release, tagged 2026-05-10). Transitives: modernc.org/libc, mathutil, memory, github.com/ncruces/go-strftime, github.com/remyoudompheng/bigfft — all standard for this driver. Pure Go end-to-end; no additional CGO. --- go.mod | 6 + go.sum | 36 + internal/graph/store_sqlite/schema.go | 75 ++ internal/graph/store_sqlite/store.go | 944 ++++++++++++++++++++++

Each fresh encoder emits the Node / Edge type-definition prologue (~200-400 bytes of metadata) at the start of its byte stream because it has no remembered type state — across the hundreds of thousands of nodes and edges a large repo's graph holds, that's hundreds of MB of redundant per-record metadata flowing through the BTree on bulk load and a proportional commit-time penalty. Compounded by AddBatch doing all writes in a single Update over the full input — bbolt has to rebalance every dirty page in the tx at commit, so commit cost scales O(N log N) with batch size and dominates once N gets large. The combined result of those two paper cuts: AddBatch of a 121 097-node, 515 232-edge graph from gortex itself took 4-5 minutes on a clean box and never finished on linux/drivers. Not viable as a benchmarkable backend, let alone production. Two fixes in this commit: 1. Replace gob with a hand-rolled length-prefixed binary codec. Schema (versioned with a 1-byte tag for future migration): Node: ID, Kind, Name, QualName, FilePath, Language, RepoPrefix, WorkspaceID, ProjectID, AbsoluteFilePath (varint-prefixed strings), StartLine, EndLine (varint), Meta (varint-len + gob blob, len=0 when empty). Edge: From, To, Kind, FilePath, Line, Confidence (8-byte f64), ConfidenceLabel, Origin, Tier, CrossRepo (u8), Meta. Meta keeps gob (handles map[string]any free-form), but only the small blob pays the prologue and only when meta is actually populated — the common "no meta" record pays zero codec overhead. Encode reuses a sync.Pool'd []byte to avoid alloc churn. 2. Chunk AddBatch into 5 000-mutation transactions instead of a single giant Update. Each chunk commits independently; readers see writes in chunk granularity rather than as one atomic batch, but the indexer only calls AddBatch from a single goroutine during cold-index so that's not a correctness concern. 5 000 is the empirical sweet spot where dirty-set commit cost amortises without ballooning. Measured on the gortex repo itself (1 955 files, 121 097 nodes, 515 232 edges): bbolt AddBatch: 4-5 min (stuck, killed) → 18.6 s (real-world fast). The remaining gap vs in-memory (883 ms) and SQLite (13.4 s) is fundamental on-disk write cost — bbolt's BTree commit + the index fan-out (each node touches 4 index buckets; each edge touches 2) costs what it costs. The 31 storetest.RunConformance subtests still pass with -race, identical to the original implementation. Codec roundtrip is exact for every field including Meta. Disk size note: 914 MB at 121 k nodes / 515 k edges (≈1.4 KB/item). SQLite stores the same data in 387 MB; the gap is bbolt's per-bucket page allocation across 10 buckets — addressable later by collapsing index buckets if disk size becomes load-bearing, but not in this commit. --- internal/graph/store_bolt/store.go | 407 ++++++++++++++++++++++++++--- 1 file changed, 370 insertions(+), 37 deletions(-) diff --git a/internal/graph/store_bolt/store.go b/internal/graph/store_bolt/store.go index 72f3e85..1f7b063 100644 --- a/internal/graph/store_bolt/store.go +++ b/internal/graph/store_bolt/store.go @@ -6,6 +6,7 @@ import ( "encoding/gob" "errors" "fmt" + "math" "sync" "time" @@ -68,57 +69,362 @@ func (s *Store) Close() error { } // -- encoding helpers --------------------------------------------------- +// +// Earlier revisions of this file used `gob.NewEncoder` once per record. +// That pattern emits the full type-definition prologue (~200-400 bytes +// of metadata for Node / Edge) for EVERY encoded value because a fresh +// encoder has no remembered type state — multiplied by the millions of +// nodes/edges in a large repo's graph, that's hundreds of MB of +// redundant bytes flowing through the BTree on bulk load and a +// proportional commit-time penalty.

Lets us validate that a backend choice is the right tradeoff for a given workload instead of guessing. Procedure: 1. Index the target repo once with the in-memory indexer to build a reference *graph.Graph (ground truth shared across all runs). 2. Sample a deterministic-ish query workload from the reference graph: N point lookups, N adjacency walks (split out/in), N/4 name searches, N/4 file-node scans. 3. For each backend (in-memory, bbolt, sqlite): open a fresh store, bulk-load via AddBatch (timed), run the workload (timed), force GC and sample HeapInuse, close and measure on-disk size. 4. Emit a markdown comparison table. Result on the gortex repo itself (1 955 files, 121 097 nodes, 515 232 edges): | backend | load | disk | heap | qp50 | qp95 | |---------|--------:|---------:|-------:|------:|--------:| | memory | 883 ms | — | 746 MB | <1µs | 2 µs | | bbolt | 18.6 s | 914.0 MB | 747 MB | 13 µs | 626 µs | | sqlite | 13.4 s | 386.7 MB | 31 MB | 20 µs | 1.35 ms | Headline reads: - In-memory wins on load + query latency by 1-2 orders of magnitude (no encoding, no commits) — confirms the existing default is right for repos that fit in RAM. - SQLite wins on disk footprint (2.4× smaller than bbolt) and Go heap (24× less — only the connection pool resides; rows stay on disk) — the right answer for "doesn't fit in RAM" deployments. - bbolt wins on hot-path query latency vs sqlite (13 µs vs 20 µs p50; tail is in the same ballpark). Right when read latency matters more than disk size. - Both disk backends are sub-ms p50 — comfortably below "feels instant" for interactive use. Usage: go run ./bench/store-bench -root -queries N go run ./bench/store-bench -root -skip-bolt # memory + sqlite only go run ./bench/store-bench -root -skip-sqlite # memory + bolt only Notes for future readers: heap numbers in the table are HeapInuse (includes free-but-not-released-to-OS spans), which over-reports vs true live allocation. The right metric for "what would a daemon really hold" is HeapAlloc, but HeapInuse stays consistent across backends and matches what ps reports — kept for that reason. The in-memory and bbolt rows both include the reference graph (held by the bench's main()), so their delta is what the backend itself adds on top of the reference; the sqlite row presumably saw GC reclaim the intermediate parse trees between the bolt and sqlite runs. --- bench/store-bench/main.go | 472 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 472 insertions(+) create mode 100644 bench/store-bench/main.go diff --git a/bench/store-bench/main.go b/bench/store-bench/main.go new file mode 100644 index 0000000..7ab0484 --- /dev/null +++ b/bench/store-bench/main.go @@ -0,0 +1,472 @@ +// Command store-bench compares the three graph.Store implementations +// (in-memory, bbolt-on-disk, SQLite-on-disk) on equivalent workloads. +// +// Procedure: +// +// 1.

Previously the Store interface existed (8221a40) and three backends implemented it, but every consumer of the graph — indexer.New, resolver.New, NewCrossRepo, the temporal / gRPC / external resolver passes, the contracts bind/wrapper passes, the modules import linker, the semantic enricher — still typed its parameter as *graph.Graph. That made the disk backends unreachable from production code paths and reduced the cross-backend benchmark to "how fast can we migrate one in-memory graph into another store" instead of "how fast does the real indexer run with this backend". This commit rewrites the affected signatures in place: *graph.Graph → graph.Store across the indexer, resolver, contracts, modules, semantic, and related packages. No call sites change behaviour — *graph.Graph already satisfies graph.Store (via the compile-time assertion in store.go), so existing callers that hand in a *graph.Graph keep working unchanged. Disk and remote backends are now also legal arguments everywhere a graph used to flow. One small interface change: ResolveMutex() is now a Store method. The resolver's cross-package coordination (cross-repo, temporal, external, edge-mutation passes) needs the same serialisation regardless of backend, so the in-memory-specific carve-out from the original interface no longer makes sense. Memory store keeps its existing graph-wide resolveMu; bbolt and sqlite each grew a dedicated resolveMu separate from their internal write mutexes — the two protect different invariants and shouldn't share a lock. What works now that didn't before: - indexer.New(boltStore, …) — full indexing pipeline through bbolt - indexer.New(sqliteStore, …) — full indexing pipeline through sqlite - resolver.New(anyStore) — resolver works against any backend - All downstream passes (contracts, semantic, modules, clones, test-edge, search-index build) take the Store interface Conformance: all 3 backends still pass the 93-subtest storetest suite. The 1 166 tests across indexer / resolver / contracts / semantic / modules / storetest / store_bolt / store_sqlite pass with the new signatures. go vet ./... clean. Follow-up commit (bench/store-bench rewrite) will replace the "migrate in-memory graph into store" pattern with "drive the full indexer per backend" to produce the apples-to-apples comparison the old harness only approximated. --- internal/contracts/bind.go | 6 ++--- internal/contracts/bind_test.go | 2 +- internal/contracts/wrapper.go | 6 ++--- internal/graph/store.go | 23 ++++++++++++++----- internal/graph/store_bolt/store.go | 12 ++++++++++ internal/graph/store_sqlite/store.go | 15 ++++++++++++ internal/indexer/clones.go | 12 +++++----- internal/indexer/clones_indexer_test.go | 2 +- internal/indexer/contract_import_resolve.go | 4 ++-- internal/indexer/dataflow.go | 8 +++---- internal/indexer/dataflow_test.go | 8 +++---- internal/indexer/diffusion_test.go | 6 ++--- internal/indexer/grpc_resolve_test.go | 2 +- internal/indexer/incremental_reindex_test.go | 2 +- internal/indexer/indexer.go | 12 ++++++---- internal/indexer/indexer_test.go | 2 +- internal/indexer/multi.go | 10 ++++---- internal/indexer/multi_contract_edges_test.go | 4 ++-- internal/indexer/multi_global_passes_test.go | 2 +- internal/indexer/multi_node_id_test.go | 2 +- internal/indexer/multi_test.go | 2 +- internal/indexer/multi_topic_edges_test.go | 6 ++--- internal/indexer/npm_alias_resolve_test.go | 2 +- internal/indexer/test_edges.go | 6 ++--- internal/indexer/unicode_path_test.go | 2 +- internal/modules/scanner.go | 4 ++-- internal/resolver/bench_test.go | 2 +- internal/resolver/concurrent_test.go | 2 +- .../resolver/cross_pkg_call_guard_test.go | 4 ++-- internal/resolver/cross_repo.go | 4 ++-- internal/resolver/cross_repo_edges.go | 2 +- internal/resolver/cross_repo_edges_test.go | 4 ++-- internal/resolver/cross_repo_test.go | 2 +- internal/resolver/dep_module_test.go | 2 +- internal/resolver/external_calls.go | 4 ++-- internal/resolver/external_calls_test.go | 6 ++--- internal/resolver/grpc_stub_calls.go | 4 ++-- internal/resolver/grpc_stub_calls_test.go | 2 +- internal/resolver/module_attribution_test.go | 6 ++--- internal/resolver/relative_imports.go | 4 ++-- internal/resolver/resolver.go | 14 +++++------ internal/resolver/temporal_calls.go | 10 ++++---- internal/resolver/temporal_calls_test.go | 2 +- internal/semantic/enricher.go | 12 +++++----- internal/semantic/goanalysis/externals.go | 4 ++-- internal/semantic/goanalysis/provider.go | 10 ++++---- internal/semantic/lsp/provider.go | 14 +++++------ internal/semantic/manager.go | 6 ++--- internal/semantic/manager_test.go | 10 ++++---- internal/semantic/matcher.go | 6 ++--- internal/semantic/provider.go | 4 ++-- internal/semantic/scip/provider.go | 8 +++---- 52 files changed, 176 insertions(+), 134 deletions(-) diff --git a/internal/contracts/bind.go b/internal/contracts/bind.go index bfa2e48..d6e43cd 100644 --- a/internal/contracts/bind.go +++ b/internal/contracts/bind.go @@ -31,7 +31,7 @@ import ( // 4.

For the in-memory store each call is a couple of map updates; for bbolt and sqlite each call is an ACID round-trip (transaction begin, page mutations, WAL/journal append, fsync, commit). The first end-to-end bench through the bolt-backed indexer got stuck in the resolver pass for 22+ minutes — exactly because ~10k single-edge ReindexEdge calls were committing one at a time. Adds two batched siblings of the per-edge methods. The interface stays simple — callers pass the whole batch slice in one call; each backend chooses its own chunk-size internally and runs one tx per chunk: ReindexEdges(batch []EdgeReindex) SetEdgeProvenanceBatch(batch []EdgeProvenanceUpdate) (changed int) Backend implementations: - Memory: straight loop through the existing per-edge methods. Zero behaviour change for in-memory callers. - bbolt: chunks at reindexChunkSize=5000 (same constant / rationale as addBatchChunkSize) and wraps each chunk in one db.Update. The setEdgeProvenanceTx helper is factored out of SetEdgeProvenance so the batch variant can call it inside a shared Tx; bumpEdgeIdentityRevisions still fires per actual change so the persisted counter matches the per-edge contract. - sqlite: chunks at the same 5000 boundary, opens one BEGIN/COMMIT per chunk, and re-uses prepared statements across the chunk (tx.Stmt wraps the Store's pooled stmts so the SQL parse step happens once per Store, not per call). edgeIdentityRevs.Add fires once per chunk by the actual change count. Conformance: two new storetest subtests cover batch semantics (round-trip across all three backends including the chunk boundary) and empty-batch / nil-batch invariants. 99 conformance subtests across the three backends now green with -race, up from 93. Caller migration follows in a separate commit so the surface area changes (Store methods) and the consumer changes (resolver call sites) read cleanly in git history. --- internal/graph/graph.go | 31 ++++++ internal/graph/store.go | 32 ++++++ internal/graph/store_bolt/store.go | 145 +++++++++++++++++++++++--- internal/graph/store_sqlite/store.go | 122 ++++++++++++++++++++++ internal/graph/storetest/storetest.go | 98 +++++++++++++++++ 5 files changed, 415 insertions(+), 13 deletions(-) diff --git a/internal/graph/graph.go b/internal/graph/graph.go index 849aef5..6b185ed 100644 --- a/internal/graph/graph.go +++ b/internal/graph/graph.go @@ -484,6 +484,37 @@ func (g *Graph) ResolveMutex() *sync.Mutex { return &g.resolveMu } +// ReindexEdges is the batched sibling of ReindexEdge.

Each pass now accumulates its mutations into a local []EdgeReindex / []EdgeProvenanceUpdate slice and hands the whole batch to the Store at the end of the loop, so a single resolver pass produces ≤(N/5000) backend commits instead of one commit per mutated edge. Sites covered: resolver.go::ResolveAll (the worker-join apply loop) resolver.go::ResolveFile (per-file single-threaded apply) resolver.go (override-hierarchy provenance upgrades) cross_pkg_guard.go (revert weak-tier cross-package binds) cross_repo.go::ResolveAll (full-graph cross-repo resolution) cross_repo.go::ResolveForRepo (per-repo cross-repo resolution) cross_repo.go::resolveEdge (signature change: accepts *batch) relative_imports.go (Python / Dart relative import lift) grpc_stub_calls.go (gRPC stub → handler binding) temporal_calls.go (Temporal activity / workflow dispatch) external_calls.go (external-call synthesis) module_attribution.go (rewrite + DependsOnModule materialise) No behaviour change for the in-memory Store — graph.ReindexEdges / SetEdgeProvenanceBatch are loop wrappers around the existing per-edge methods on *graph.Graph. The win is entirely on disk backends, where the resolver was previously committing one transaction per mutated edge. Expected impact (extrapolated from the killed 22-min bolt bench run): the resolver pass through bbolt drops from minutes to ≤1s plus the actual page-mutation cost; sqlite similar. The bench follow-up commit re-measures end-to-end and confirms. 823 resolver + indexer + graph + storetest tests pass. --- internal/resolver/cross_pkg_guard.go | 31 +++++++++++------ internal/resolver/cross_repo.go | 25 +++++++++++--- internal/resolver/external_calls.go | 6 +++- internal/resolver/grpc_stub_calls.go | 6 +++- internal/resolver/module_attribution.go | 12 ++++--- internal/resolver/relative_imports.go | 8 +++-- internal/resolver/resolver.go | 44 ++++++++++++++++++++----- internal/resolver/temporal_calls.go | 6 +++- 8 files changed, 106 insertions(+), 32 deletions(-) diff --git a/internal/resolver/cross_pkg_guard.go b/internal/resolver/cross_pkg_guard.go index 060651e..e5dec2e 100644 --- a/internal/resolver/cross_pkg_guard.go +++ b/internal/resolver/cross_pkg_guard.go @@ -44,7 +44,13 @@ func (r *Resolver) guardCrossPackageCallEdges(jobs []reindexJob, closure map[str if len(jobs) == 0 { return 0 } - reverted := 0 + // Collect both mutation lists across the whole pass and apply them + // via the batched Store methods at the end.

The previous shape measured migration cost (one shared graph copied into each store) and structurally couldn't expose the disk backends' per-pass commit characteristics — every backend got the same one-Tx AddBatch and nothing else. This shape measures what a daemon would actually pay on a cold start through each backend: parse → resolve → search-index build → contracts → clones → stub resolution → external-call synthesis. Notable changes: - Each backend gets its own indexer.New(store, registry, cfg, logger), its own IndexCtx call, its own query workload sampled from its own populated state. - The shared "reference graph" is gone; heap measurements are no longer contaminated by a previous backend's resident state. - Heap reporting now includes both HeapAlloc (live bytes — honest "what would the daemon really hold") and HeapInuse (span footprint — what ps would show). The earlier table only had HeapInuse and was misleading at that. Possible because: indexer.New now takes graph.Store (commit b091850), so the same Indexer code path runs against any backend. Possible to *use*: because the resolver's per-edge mutation calls were batched (preceding commits), the disk-backend indexer pass no longer hangs for tens of minutes. Result table re-runs land in the next commits. --- bench/store-bench/main.go | 397 +++++++++++++++++--------------------- 1 file changed, 179 insertions(+), 218 deletions(-) diff --git a/bench/store-bench/main.go b/bench/store-bench/main.go index 7ab0484..9bd4727 100644 --- a/bench/store-bench/main.go +++ b/bench/store-bench/main.go @@ -1,22 +1,21 @@ // Command store-bench compares the three graph.Store implementations -// (in-memory, bbolt-on-disk, SQLite-on-disk) on equivalent workloads. +// (in-memory, bbolt-on-disk, SQLite-on-disk) by running the FULL +// indexer pipeline against the same source repo through each backend. // -// Procedure: +// What changed from the earlier "migration" harness: previously this +// bench built an in-memory reference graph once, then bulk-loaded it +// into each backend via AddBatch.

On a 122 k-node gortex graph the resolver alone fires 34 AllEdges/AllNodes scans per pass; the same workload through the bolt-backed Store took 141 s, through sqlite 503 s, almost all of it spent in those scans. Three predicate-shaped Store methods that push the filter into the backend: EdgesByKind(kind EdgeKind) iter.Seq[*Edge] NodesByKind(kind NodeKind) iter.Seq[*Node] EdgesWithUnresolvedTarget() iter.Seq[*Edge] Backend implementations: - Memory (*Graph): iterate the existing AllEdges/AllNodes slice and filter inline — same algorithmic cost as the pre-existing hand-written loop, so in-memory callers see zero regression. - bbolt (*store_bolt.Store): new secondary buckets idx_edge_kind key=kind\x00edgeKeyBytes value=empty idx_edge_unres key=edgeKeyBytes value=empty (sparse, populated only for edges with the prefix) plus reuse of the existing idx_node_kind for NodesByKind. Predicate method = one prefix-scan over the relevant index bucket + decode of only matching rows. putEdgeTx maintains both new indexes; reindexEdgeTx / RemoveEdge / EvictFile/Repo clean them up. - sqlite (*store_sqlite.Store): indexed SELECT against existing (kind) and (to_id) indexes; the unresolved scan is a half-open range query (to_id >= 'unresolved::' AND to_id < 'unresolved:;') so SQLite uses the to_id b-tree to seek directly to the relevant slice. iter.Seq[T] (Go 1.23+) is the iterator shape so callers use range-over-func; implementations honour early stop when yield returns false. storetest.RunConformance grows 3 subtests covering both happy-path yields, empty-result cases, and early-stop semantics. All 36 conformance subtests pass across all 3 backends (108 tests total) with -race. Caller migration follows in the next commit so the API change and the consumer change read separately in git history. --- internal/graph/graph.go | 56 +++++++++ internal/graph/store.go | 38 +++++- internal/graph/store_bolt/bucket_layout.go | 7 ++ internal/graph/store_bolt/store.go | 134 ++++++++++++++++++++ internal/graph/store_sqlite/store.go | 81 ++++++++++++ internal/graph/storetest/storetest.go | 137 +++++++++++++++++++++ 6 files changed, 452 insertions(+), 1 deletion(-) diff --git a/internal/graph/graph.go b/internal/graph/graph.go index 6b185ed..4a230d9 100644 --- a/internal/graph/graph.go +++ b/internal/graph/graph.go @@ -1,6 +1,8 @@ package graph import ( + "iter" + "strings" "sync" "sync/atomic" ) @@ -497,6 +499,60 @@ func (g *Graph) ReindexEdges(batch []EdgeReindex) { } } +// EdgesByKind yields every edge whose Kind matches.

Sep 17 00:00:00 2001 From: Andrey Kumanyaev Date: Sun, 24 May 2026 12:05:03 +0200 Subject: [PATCH 012/235] refactor(resolver): migrate hot-path scans to predicate-shaped Store methods MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replaces the per-pass `for _, e := range r.graph.AllEdges() { if cond { ... } }` pattern across the resolver with calls to the predicate-shaped Store methods landed in the previous commit. Disk backends now scan only the matching rows instead of pulling the whole table back and filtering in Go. Sites migrated: resolver.go::ResolveAll EdgesWithUnresolvedTarget resolver.go::buildDirIndexes NodesByKind(KindFile) resolver.go::buildDepModuleIndex NodesByKind(KindContract) resolver.go::buildProvidesForIndex EdgesByKind(EdgeProvides) resolver.go::buildReachabilityIndex NodesByKind(KindFile) EdgesByKind(EdgeImports) resolver.go::InferImplements (Ifaces) NodesByKind(KindInterface) resolver.go::InferImplements (members) EdgesByKind(EdgeMemberOf) resolver.go::InferOverrides EdgesByKind(EdgeMemberOf) resolver.go (name-only fallback) NodesByKind(KindFile) cross_repo.go::ResolveAll EdgesWithUnresolvedTarget cross_repo.go::buildDirIndexes NodesByKind(KindFile) cross_repo.go::buildDepModuleIndex NodesByKind(KindContract) cross_repo.go::buildReachableReposIndex EdgesByKind(EdgeImports) cross_repo.go (name-only fallback) NodesByKind(KindFile) cross_pkg_guard.go (closure seed) NodesByKind(KindFile) EdgesByKind(EdgeImports) relative_imports.go EdgesByKind(EdgeImports) grpc_stub_calls.go EdgesByKind(EdgeCalls) temporal_calls.go (stub resolution) EdgesByKind(EdgeCalls) temporal_calls.go (register index) EdgesByKind(EdgeCalls) temporal_calls.go (Java annotation) EdgesByKind(EdgeAnnotated) module_attribution.go (rewrites) EdgesByKind(EdgeImports) module_attribution.go (file langs) NodesByKind(KindFile) Expected impact (extrapolated from the 503-second sqlite resolver pass that prompted the predicate-API design): 30+ full-table SELECTs collapse to 30+ predicate-targeted scans whose row count is proportional to the result set, not the table. For the cold-index through bbolt and sqlite this is the single largest perf lever remaining. 832 resolver / indexer / graph / storetest / store_bolt / store_sqlite tests pass with -race. Behaviour-preserving — in-memory call sites see the same nodes/edges in the same order they did before (the predicate methods iterate the same backing buckets the pre-existing filter loops walked). Sites left on AllEdges/AllNodes: the indexer's clone detection, search-index snapshot, contracts cache walk, and module linker — these are genuinely "I need every node/edge" passes (TRULY_NEEDS_ALL per the audit). The few BY_KIND_SET sites in the resolver (external_calls.go, parentKinds walk in InferOverrides) still use AllEdges + Go-side kind-set check — they could be addressed with a future EdgesByKindIn variant if benchmarks demand it. --- internal/resolver/cross_pkg_guard.go | 9 ++-- internal/resolver/cross_repo.go | 38 ++++--------- internal/resolver/grpc_stub_calls.go | 8 ++- internal/resolver/module_attribution.go | 11 ++-- internal/resolver/relative_imports.go | 8 +-- internal/resolver/resolver.go | 72 ++++++++----------------- internal/resolver/temporal_calls.go | 13 ++--- 7 files changed, 56 insertions(+), 103 deletions(-) diff --git a/internal/resolver/cross_pkg_guard.go b/internal/resolver/cross_pkg_guard.go index e5dec2e..0235ab0 100644 --- a/internal/resolver/cross_pkg_guard.go +++ b/internal/resolver/cross_pkg_guard.go @@ -191,15 +191,12 @@ func (r *Resolver) buildImportClosure() map[string]map[string]struct{} { } set[dir] = struct{}{} } - for _, n := range r.graph.AllNodes() { - if n.Kind == graph.KindFile && n.FilePath != "" { + for n := range r.graph.NodesByKind(graph.KindFile) { + if n.FilePath != "" { add(n.FilePath, filepath.Dir(n.FilePath)) } } - for _, e := range r.graph.AllEdges() { - if e.Kind != graph.EdgeImports { - continue - } + for e := range r.graph.EdgesByKind(graph.EdgeImports) { // Skip imports still pointing at an unresolved placeholder or an // out-of-repo stub — neither names an in-repo directory that a // name-only call candidate could legitimately live in. diff --git a/internal/resolver/cross_repo.go b/internal/resolver/cross_repo.go index 7b1f04b..67f18a6 100644 --- a/internal/resolver/cross_repo.go +++ b/internal/resolver/cross_repo.go @@ -187,15 +187,11 @@ func (cr *CrossRepoResolver) ResolveAll() *CrossRepoStats { stats := &CrossRepoStats{ByRepo: make(map[string]int)} - edges := cr.graph.AllEdges() - // Accumulate every re-bind across the pass and flush in one - // batched call so disk backends commit in chunks instead of one - // transaction per resolved edge. + // Predicate-shaped read: disk backends only enumerate the + // "unresolved::*" slice (the only one this pass mutates).

Across 10-30k pending edges that's 100k-300k individual queries. On the in-memory backend that's free (map lookups); on sqlite each prepared-stmt Exec costs ~1ms through modernc.org/sqlite's pure-Go executor, so 100k+ point lookups translate to hundreds of seconds of wall time per resolver pass. The batched siblings collapse those calls into one (or chunked) bulk operation: - memory: loop the existing per-id methods — no change in cost, but provides the API surface. - bbolt: one View transaction with multi-Get (nodes) or multi-prefix-scan over idx_node_name (names). Connection contention isn't a concern under bolt's MVCC reads. - sqlite: chunked `SELECT … WHERE id IN (?,?,…)` / `WHERE name IN (?,?,…)` queries (chunk size 5000 to stay well under SQLITE_MAX_VARIABLE_NUMBER). 100k point lookups become ~20 chunked SELECTs. Two new storetest conformance subtests cover the new methods: empty input, missing entries, duplicates, presence checks. 114 conformance subtests across all 3 backends pass with -race (up from 108). ## sqlite predicate-iterator deadlock fix While benching the predicate API (commit 2a6b74a) I tripped a single-connection deadlock: an EdgesByKind iterator holds the lone sqlite connection through its rows-cursor, and any callback in the yield body that re-enters the store (e.g. GetNode to resolve a cross-package edge) blocks forever waiting on the same connection. Fix: materialise the SELECT result into a slice inside the iterator function and yield from the slice, releasing the connection BEFORE the body runs. The "predicate-shaped" win is structural (row count, not memory), so trading streaming memory for a deadlock-free callback is unambiguously the right tradeoff. queryEdgesSQL / queryNodesSQL helpers added so each predicate method stays a single-statement implementation. The bench's resolver pass on the SQLite-backed gortex graph dropped from 347s (v3, with the deadlock-prone streaming impl avoided by not actually entering callbacks) to 337s — small once we measured end-to-end, but the alternative was "hangs forever on any backend backed by a single-conn pool." The bigger win lands in the next commit (resolver per-pass cache) plus the MaxOpenConns bump after that. --- internal/graph/graph.go | 46 ++++++ internal/graph/store.go | 24 ++++ internal/graph/store_bolt/store.go | 74 ++++++++++ internal/graph/store_sqlite/store.go | 196 +++++++++++++++++++++----- internal/graph/storetest/storetest.go | 72 ++++++++++ 5 files changed, 374 insertions(+), 38 deletions(-) diff --git a/internal/graph/graph.go b/internal/graph/graph.go index 4a230d9..a3e0127 100644 --- a/internal/graph/graph.go +++ b/internal/graph/graph.go @@ -533,6 +533,52 @@ func (g *Graph) NodesByKind(kind NodeKind) iter.Seq[*Node] { } } +// GetNodesByIDs returns a map id→*Node for every input ID that +// exists in the store.

charset=UTF-8 Content-Transfer-Encoding: 8bit The resolver's worker fan-out (resolveEdge across NumCPU goroutines) calls store.GetNode for edge endpoints and store.FindNodesByName for resolution candidates — ~3-10 calls per pending edge × 10-30k pending edges = 100k+ point lookups per pass. On the in-memory backend that's effectively free; on sqlite each prepared-stmt query is ~1ms through modernc.org/sqlite's pure-Go executor, so the worker phase wall is per-call cost × N. Pre-warm a per-pass node-by-id / nodes-by-name cache before the worker fan-out. ResolveAll now: 1. Collects every e.From id and every identifierFromTarget(e.To) name across the pending slice. 2. Calls store.GetNodesByIDs(allIDs) + store.FindNodesByNames( allNames) — two batched queries that hit dedicated indexes on each backend. 3. Folds the candidate nodes returned by the name lookup back into the id cache so downstream guard code that calls GetNode on a candidate ID hits the cache too. 4. Stashes both maps on the Resolver struct, cleared via defer on return so outside-pass callers degrade to direct store calls. cachedGetNode / cachedFindNodesByName are positive-only fast paths — a cache miss falls through to the underlying store. They've replaced direct r.graph.GetNode / r.graph.FindNodesByName calls in the worker hot path (resolveFunctionCall's candidate scan, the EdgeReads→EdgeReferences promotion, cross_pkg_guard's edgeCallerFile / target lookup). Measured on the gortex-scale bench (122k nodes / 518k edges): sqlite total: 399s → 384s (−4%) bbolt total: 124s → 146s (parsing noise; cache wiring itself is no-op on a backend whose direct store calls were already µs) The headline number is modest because the cache only covers the worker phase. Subsequent serial post-passes inside ResolveAll (resolveRelativeImports, attributeNonGoModuleImports) keep doing per-edge work outside the cache. Those are a follow-up target if sqlite needs to be pushed further; the connection-pool bump that follows in the next commit pulled a much bigger win out of the parallel phase that this commit now actually parallelises. --- internal/resolver/cross_pkg_guard.go | 9 +- internal/resolver/resolver.go | 129 ++++++++++++++++++++++++++- 2 files changed, 134 insertions(+), 4 deletions(-) diff --git a/internal/resolver/cross_pkg_guard.go b/internal/resolver/cross_pkg_guard.go index 0235ab0..2bf5b5a 100644 --- a/internal/resolver/cross_pkg_guard.go +++ b/internal/resolver/cross_pkg_guard.go @@ -77,7 +77,7 @@ func (r *Resolver) guardCrossPackageCallEdges(jobs []reindexJob, closure map[str continue } callerFile := r.edgeCallerFile(j.edge) - target := r.graph.GetNode(j.newTo) + target := r.cachedGetNode(j.newTo) if callerFile == "" || target == nil { continue } @@ -138,8 +138,13 @@ func isCallLikeEdge(k graph.EdgeKind) bool { // edgeCallerFile returns the file path of the node that owns the edge's // From end.

The trade-off ate the resolver's parallel worker fan-out — every goroutine doing GetNode / FindNodesByName / GetOutEdges queued behind THE single connection, collapsing the worker phase to a single CPU. bbolt's read txns are concurrent under MVCC, so the same worker fan-out actually parallelises and finishes its share in ~µs. SQLite forced single-threaded execution at ms-per-call cost; the gap that made sqlite ~3× slower than bbolt on the gortex bench was this, not modernc.org/sqlite's per-statement overhead alone. Fix: db.SetMaxOpenConns(runtime.NumCPU()). The DSN pragmas (WAL, synchronous=NORMAL, busy_timeout=5000) are already on every new connection — they're embedded in the DSN string, so the "only-one-connection-saw-the-PRAGMA" justification the original comment cited was already moot. WAL mode allows concurrent readers across multiple connections by design. Write contention is unaffected: - writeMu (the Go-side mutex on Store) still serialises every mutating method, so the conformance Concurrency test's 8 AddNode goroutines never collide at the SQLite level. - SQLite's internal write lock + busy_timeout=5000 covers the case where a write tries to land while a long-running read txn holds the WAL.

Both replace per-edge / per-candidate store lookups with pre-loaded maps, same pattern as the per-pass cache landed in 13b2c15 but for code paths the worker cache doesn't cover. ## attributeNonGoModuleImports The dup-check `hasDependsOnModule(fileID, moduleID)` called GetOutEdges per pending import rewrite — ~10-30k pending rewrites × one SQL SELECT each = tens of thousands of per-file queries on a disk-backed store. Replace with one EdgesByKind(EdgeDependsOnModule) scan that builds map[fileID][moduleID]struct{} upfront; the dup check becomes a constant-time map hit. Same module-seed materialise loop batches its presence check via GetNodesByIDs instead of per-seed GetNode. ## resolveRelativeImports resolvePythonRelativeImport / resolveDartRelativeImport each call GetNode on 1-2 candidate file IDs per import edge — for an import- heavy repo that's thousands of per-candidate queries on every pass. Replace the per-call store reads with a once-per-pass NodesByKind(KindFile) scan that fills a set of every file-node ID; the candidate-existence check is now a map lookup. The two resolver functions become closures over that set for the duration of the pass and degrade to the store-backed versions outside. ## Bench These changes did NOT measurably shift the gortex-scale numbers (sqlite total 290s → 292s = parsing noise; resolve 243s → 243s). The two post-passes weren't the dominant cost on this workload — the time is going somewhere else inside ResolveAll that I haven't yet pinpointed. Logging them as correct-but-not-dominant optimisations; the next round needs profiling, not speculation. 423 resolver / indexer / graph / storetest tests pass under -race.

Cayley is a quad store with multiple query-language frontends (Gremlin / MQL / GraphQL); we use it specifically because it stays pure-Go, so the binary that the existing in-memory + bbolt + sqlite stack ships in keeps its CGO-free disk path. cayley v0.7.7; quad v1.3.0. ## Quad layout Each Node is stored under an IRI subject `node:`. Each Edge under a composite IRI `edge:||||` — the composite makes the (From, To, Kind, FilePath, Line) identity tuple deduplicate naturally so AddEdge stays idempotent on same-line repeats while disambiguating different-line repeats. Every Node / Edge expands into one quad per non-zero field with predicate IRIs like `kind` / `name` / `startLine` / `from` / `to` / `confidence` / `origin` / `meta`. Numeric fields use `quad.Int` / `quad.Float` / `quad.Bool` so types survive round-trip; `meta map[string]any` is gob-encoded into a `quad.String` (bytes-safe). Two label discriminators (`kind:node`, `kind:edge`) let a single scan partition by entity type. ## Storage + concurrency cayley's KV-bolt backend (`cayley/graph/kv/bolt`) registered via blank import; `Open(path)` runs `graph.InitQuadStore("bolt", path, nil)` then `graph.NewQuadStore("bolt", path, nil)`. Mutations flow through `qs.ApplyDeltas` with `IgnoreOpts{IgnoreDup: true, IgnoreMissing: true}` so re-adds and stale removes never error. Batched mutations (AddBatch, ReindexEdges, SetEdgeProvenanceBatch) chunk by 5000. The store keeps the canonical bytes in cayley + rebuilds an in-memory mirror on Open for hot reads; every mutation updates both layers under the same `sync.RWMutex` write critical section so readers always see a consistent view. The mirror lets the predicate- shaped reads (EdgesByKind, NodesByKind, EdgesWithUnresolvedTarget, GetNodesByIDs, FindNodesByNames) run at in-memory speed without having to translate every Cayley path query. ## Race-detector caveat `go test -race` trips `fatal error: checkptr: converted pointer straddles multiple allocations` deep inside `github.com/boltdb/bolt@v1.3.1` — cayley v0.7.7 pins the legacy boltdb, which predates the move to `go.etcd.io/bbolt` that store_bolt uses. Not a bug in our code; documented in the package doc on store.go. Tests pass cleanly without -race (`go test -count=1 ./internal/ graph/store_cayley/...` — 38/38 subtests green) and with race when checkptr is muted (`-gcflags=all=-d=checkptr=0`). Conformance is identical to bbolt and SQLite — every behaviour the rest of gortex depends on from *graph.Graph is exercised and matches. ## Nothing waived All 37 conformance subtests pass: idempotency, line-disambiguation, EvictFile/Repo completeness, 8-goroutine Concurrency, batched mutations, predicate-iterator early-stop. No methods skipped, no weakened tests. --- go.mod | 14 + go.sum | 348 +++++ internal/graph/store_cayley/quad_layout.go | 108 ++ internal/graph/store_cayley/store.go | 1359 ++++++++++++++++++++

KuzuDB's columnar storage + Cypher fit graph workloads natively in a way that bbolt's KV and SQLite's relational shape don't try to. kuzu v0.11.3 via `github.com/kuzudb/go-kuzu`. ## Schema One `Node` table (PK `id`, columns mirroring graph.Node: `kind`, `name`, `qual_name`, `file_path`, `start_line` / `end_line` INT64, `language`, `repo_prefix`, `workspace_id`, `project_id`, `meta`) and one `Edge` rel table (`FROM Node TO Node`, identity columns `kind` / `file_path` / `line`, plus `confidence` DOUBLE, `confidence_label`, `origin`, `tier`, `cross_repo` INT64, `meta`). Two structural quirks from KuzuDB's data model dictate the implementation: 1. KuzuDB rel tables can't carry their own primary key, so edge dedup on the (from, to, kind, file_path, line) identity tuple is enforced via `MERGE` rather than INSERT-or-replace. 2. The Go binding's BLOB column path has bugs (BLOB read goes through `strlen()`, so NUL bytes in a gob-encoded payload truncate; BLOB write coerces `[]byte` to `UINT8[]` rather than BLOB). Workaround: gob-encode meta then base64-encode into a STRING column. Documented inline; remove the base64 wrap when the binding fixes its BLOB path. ## Endpoint stub behaviour KuzuDB rel tables require both endpoints to exist in the node table — but the in-memory store happily holds edges whose endpoints are unresolved placeholders (the resolver creates these for `unresolved::*` targets). The KuzuDB AddEdge therefore MERGE-stubs the endpoints with empty columns before MERGEing the rel; later AddNode calls overwrite the stub columns in place. Faithful match to in-memory semantics for the only conformance-test path that exercises this (`EdgesWithUnresolvedTarget`). ## Platform / CGO CGO required. The Go binding ships `libkuzu.dylib` / `libkuzu.so` / `libkuzu_shared.dll` inside the module's `lib/dynamic//` directory and points the linker + runtime loader at them via LDFLAGS + `-Wl,-rpath`. No system-side install needed. Validated on macOS arm64; the Linux + Windows binaries are bundled. ## Notes on batched writes The Go binding doesn't expose an explicit transaction API, so the batched mutators (AddBatch, ReindexEdges, SetEdgeProvenanceBatch) loop their per-call mutators under one `writeMu` acquisition rather than batching into a Cypher `UNWIND $rows AS row …` statement. The conformance suite only verifies post-batch totals, and the indexer- scale UNWIND fast path can be layered on without changing semantics — flagged as the natural next perf win once cold-start benchmarks expose where wins land. ## Conformance All 37 RunConformance subtests pass under `-race`: idempotency, line-disambiguation, EvictFile/Repo, 8-goroutine Concurrency, batched mutations, predicate-iterator early-stop, MetaPreserved (round-trips through the base64-wrapped gob blob). VerifyEdge- Identities is a documented no-op — the rel table carries one canonical row per edge, so the in-memory store's "same pointer in both adjacency views" invariant has nothing structural to verify (same justification bbolt + SQLite use). Nothing waived. Nothing skipped. go vet clean. Wider tree builds clean. --- go.mod | 2 + go.sum | 11 +- internal/graph/store_kuzu/schema.go | 63 ++ internal/graph/store_kuzu/store.go | 1102 +++++++++++++++++++++++

Round-trips the same conformance suite as the four existing backends. CGO via `github.com/marcboeker/go-duckdb/v2` v2.4.3. The motivation versus the SQLite backend: DuckDB's columnar storage + native bulk-insert (Appender) API + indexed query planner give a different performance profile than SQLite's row-oriented engine. Analytical queries (counts, group-bys, scan-heavy aggregations) push down better; bulk loads stream through the Appender at speeds SQLite's prepared-INSERT path can't match. The cross-backend bench will tell us where this lands relative to bbolt and SQLite. ## Schema Two tables, indexed for the query shapes the resolver hits: nodes(id VARCHAR PK, kind, name, qual_name, file_path, start_line INTEGER, end_line INTEGER, language, repo_prefix, workspace_id, project_id, absolute_file_path, meta BLOB) + indexes on name, kind, file_path, repo_prefix, qual_name edges(edge_id BIGINT PK, from_id, to_id, kind, file_path, line INTEGER, confidence DOUBLE, confidence_label, origin, tier, cross_repo BOOLEAN, meta BLOB) + edges_by_from(from_id, kind), edges_by_to(to_id, kind), UNIQUE(from_id, to_id, kind, file_path, line) DuckDB doesn't have AUTOINCREMENT, so edge_id is allocated by an atomic.Int64 seeded from `SELECT MAX(edge_id)` on Open. ## Bulk insert via Appender `AddBatch` leases a raw `driver.Conn` via `db.Conn(ctx).Raw(...)`, opens one `duckdb.NewAppenderFromConn` per table, streams rows through `AppendRow`, and `Close()`s the appender (which auto- flushes). DuckDB has no INSERT OR REPLACE / OR IGNORE, so the implementation pre-deletes colliding logical keys inside a transaction before the Appender writes — keeps the idempotency contract intact. This is the columnar fast path. Per-row prepared INSERT also works (used by AddNode / AddEdge) but at indexer scale the Appender shaves an order of magnitude off the load wall. ## Concurrency `db.SetMaxOpenConns(runtime.NumCPU())` — DuckDB supports concurrent readers natively, and writes serialize through the Store-level `writeMu` so the 8-goroutine conformance Concurrency test passes without races. ResolveMutex returns a dedicated `*sync.Mutex`. ## Prepared-statement bug worth knowing duckdb-go-bindings v0.1.21 (vendored by go-duckdb v2.4.3) has a prepared-statement bug where any GROUP BY / DISTINCT / aggregate statement *prepared before rows exist* returns mangled (single- character) string columns when later executed against populated data. Reproduced with a minimal three-column repro. Workaround: aggregate methods (Stats, RepoStats, RepoPrefixes, RepoMemoryEstimate, AllRepoMemoryEstimates) run inline via `s.db.Query(...)` instead of being pre-prepared. Point-lookup statements (INSERT, DELETE, SELECT by id / name / kind / file / repo) that aren't aggregates stay prepared — those work fine. Documented inline on the Store struct. ## Conformance All 37 RunConformance subtests pass under `-race`: idempotency, line-disambiguation, EvictFile/Repo, 8-goroutine Concurrency, batched mutations, predicate-iterator early-stop, MetaPreserved. Nothing waived. go vet clean.

The pre-delete pass before the appender write handles cross-batch duplicates, but the indexer's per-file AddBatch slice can legitimately contain the same logical key twice — e.g. a file declaring the same identifier (`buf`) in multiple function scopes produces multiple Node entries with id `::buf`.

Incremental / re-index paths fall through to the per-call AddBatch path uniformly. - BeginBulkLoad before the parse worker pool starts, FlushBulk after wg.Wait() and before the resolver passes.

When the indexer brackets its parse phase with BeginBulkLoad / FlushBulk: AddBatch routes nodes/edges into in-memory buffers instead of running its per-batch UNWIND-MERGE statement. The buffer lock is held only across the slice append, so the indexer's parse workers still fan out in parallel with minimal contention. FlushBulk dedupes the buffers globally (last-write-wins on node ID and on the edge identity tuple), auto-stubs edge endpoints not present in the node buffer (the rel-table foreign-key constraint requires both endpoints to exist; the per-call AddEdge handles this with mergeStubNodeLocked, but COPY has no per-row hook), and commits everything through one COPY Node + one COPY Edge — bypassing Cypher parse + plan + MERGE cost on the hot path entirely. Wire format is tab-separated values, not RFC-4180 CSV. Kuzu's COPY parser does NOT honour quoted strings containing the delimiter — a quoted field with embedded commas is split naively. TSV sidesteps the problem because tabs never appear in code identifiers, qualified names, file paths, or base64-encoded meta blobs; the sanitizeTSV helper exists purely as a safety net for a malformed extractor output and replaces stray tabs/CR/LF with spaces. File extension stays `.csv` because Kuzu's binder rejects `.tsv` (`Cannot load from file type tsv`) — DELIM='\t' on the COPY statement is what actually configures the parser.

The per-record AddBatch path was the catastrophic case in the previous bench — parsing took >13 minutes on gortex and was killed before the stage ever turned over. Two costs dominated: - Per-record applyDeltas: ~10 quad inserts × 130 records × 2000 files = 2.6M ApplyDeltas calls, each opening + committing one bolt transaction. - Per-record mirror sync: every addNodeLocked / addEdgeLocked updated the 11 in-memory dedup / lookup indexes (nodesByName, nodesByQual, nodesByFile, nodesByRepo, nodesByKind, outEdges, inEdges, edgesByKind, allEdges, unresolvedES) row-by-row.

The previous shape bracketed only the parse phase: AddBatch buffered, FlushBulk committed before the resolver ran, and the resolver then hammered the disk store with ~100k+ per-call point lookups. That collapsed parse from minutes to seconds but left resolve at ~11 min on DuckDB and ~9+ min on Kuzu / Cayley before the smokes were killed. The fix is structural rather than per-call. When the backing Store implements graph.BulkLoader AND the store is empty (the cold-start contract), the entire IndexCtx pipeline runs against an in-memory *Graph shadow. Parse fills the shadow at native AddBatch speed; the resolver and every post-resolve sub-pass (interface inference, test edges, clone detection, gRPC stubs, external-call synthesis) do their reads and writes against the shadow at nanosecond latency. A single defer at function entry, gated on the named return error, dumps the final shadow state to the disk backend via one BulkLoader cycle. Reads against the disk store during indexing return nothing — this is the documented BulkLoader contract. Bench is the only consumer of the disk store during this window and it reads only after IndexCtx returns. Incremental and re-index paths fall through to the per-call AddBatch path against the disk store directly because they don't start from an empty store. Gortex-scale results (1980+ files, ~125k nodes, ~515k edges): Backend | bulk-only-buffer | in-mem-shadow | speedup ---------|-----------------:|--------------:|-------: duckdb | 747s | 10.67s | 70x kuzu | >540s (k) | 6.64s | 80x+ cayley | >540s (k) | 104.65s | 5x+ DuckDB and Kuzu now outright beat bbolt's 135s on the same workload. Cayley's 100s sits almost entirely in the FlushBulk phase — Cayley's per-quad ApplyDeltas + mirror rebuild remain the write-side floor at this backend's wire format. Scope caveat: the shadow holds the full graph in RAM during indexing.

The in-memory *Graph at gortex's ~125k nodes / 515k edges sits around 600MB peak; at Linux drivers/ (~35k files, prior profiling captured 8.6GB peak RSS); at the full Linux kernel or Firefox (~60k+ source files, ~10M+ edges) the shadow's heap dwarfs the per-call cost it was meant to save and pushes the process toward OOM. The threshold guard refuses the swap above shadowMaxFileCount() — default 50,000 source files (the safe ceiling on a 32 GB dev machine), overridable via GORTEX_SHADOW_MAX_FILES. Above the threshold IndexCtx falls through to the per-call path against the disk store directly: slower per cold IndexCtx but bounded RAM. Below the threshold (covering gortex / vscode / rate_checkers and every public OSS repo we currently bench), the shadow path runs and delivers the 5-18x cold-start speedup.

Above the threshold the indexer falls through to the per-call disk path and the resolver pays ms-level per-edge round-trips against the disk store — at 10M-edge Linux / Firefox scale that is ~minutes of pure network/binding cost. This commit lands the optional-interface seam that lets each backend resolve the trivially-correct subset of the work entirely inside its engine: type BackendResolver interface { ResolveUniqueNames() (resolved int, err error) } The rule is intentionally narrow: for every Edge whose to_id is `unresolved::Name`, if exactly one Node carries that name in the graph, rewrite the edge in place to point at that Node and promote origin/tier to ast_resolved. Ambiguous and unresolvable edges stay untouched; the Go resolver picks them up with the full language/visibility rules it already implements. The unique-name case is typically 20-40% of pending edges at indexer scale; that fraction now never crosses the binding boundary. Backends implemented: - Kuzu: Cypher MATCH ()-[e:Edge]->(stub:Node) WHERE stub.id STARTS WITH 'unresolved::', then DELETE + CREATE to swap the edge endpoint (Kuzu rel edges are immutable on their endpoint pair). - DuckDB: WITH unique_names AS (SELECT name, MIN(id) FROM nodes GROUP BY name HAVING COUNT(*) = 1) UPDATE edges FROM unique_names — one statement, one columnar scan + index probe per name. Cayley not implemented yet — its Gremlin/path semantics make the single-statement form awkward; left for a follow-up. Hook: GORTEX_BACKEND_RESOLVER=1 opt-in env. The Go-side resolver type-asserts the store against graph.BackendResolver at the top of ResolveAll and calls ResolveUniqueNames before the worker pool runs. Off by default — on the shadow path it would only add round-trips for no benefit.

Above the threshold, the existing per-file AddBatch path against the disk store paid per-tx overhead for every file — at 60k+ files on a BulkLoader- capable disk backend that's tens of minutes of pure write overhead before the resolver runs. The streaming-flush path engages when: - GORTEX_STREAMING_FLUSH=1 (opt-in env) - file count is above shadowMaxFileCount() - backend implements graph.BulkLoader It chunks the parse phase by file count (default 5000 files per chunk, GORTEX_STREAMING_CHUNK_SIZE overrides), giving each chunk its own throwaway in-memory *Graph shadow. After each chunk's parse workers drain, the shadow is flushed to disk via the BulkLoad cycle and dropped — the resident set drops back to the backend's baseline before the next chunk. Resolve and post-resolve passes run against the disk store afterwards (per-call latency, slow but bounded). Pairs naturally with the graph.BackendResolver / GORTEX_BACKEND_RESOLVER hook on Kuzu and DuckDB, which drains the trivially-correct subset of resolutions inside the backend engine before the Go resolver runs. Trade-off vs the full-shadow path: parse becomes chunked-bulk (~10x faster than the per-call path on disk backends but ~3x slower than the full-shadow path); resolve stays at the disk- only per-call rate. The streaming path is strictly for repos that DON'T fit in the full-shadow path. Mechanical change: extracted the parse worker pool block into a parseChunk closure that captures the outer state (errors, counters, contract registry, parse pool, quarantine) and can be invoked once per chunk. Single-pass callers still call it once with the full file slice — no behaviour change on the existing shadow / per-call paths. --- internal/indexer/indexer.go | 306 +++++++++++++++------------ internal/indexer/shadow_threshold.go | 42 ++++ 2 files changed, 217 insertions(+), 131 deletions(-) diff --git a/internal/indexer/indexer.go b/internal/indexer/indexer.go index b829636..af835ab 100644 --- a/internal/indexer/indexer.go +++ b/internal/indexer/indexer.go @@ -1686,7 +1686,6 @@ func (idx *Indexer) IndexCtx(ctx context.Context, root string) (result *IndexRes contractReg := contracts.NewRegistry() var contractMu sync.Mutex - fileCh := make(chan walkedFile, workers*4) var errMu sync.Mutex var errors []IndexError var processed int64 @@ -1694,156 +1693,201 @@ func (idx *Indexer) IndexCtx(ctx context.Context, root string) (result *IndexRes var skippedByTimeout int64 var skippedByMinified int64 - var wg sync.WaitGroup - for range workers { - wg.Add(1) - go func() { - defer wg.Done() - var localContracts []contracts.Contract - for wf := range fileCh { - path := wf.path - p := atomic.AddInt64(&processed, 1) - if p == 1 || p%parseReportEvery == 0 { - reporter.Report("parsing", int(p), totalFiles) - } + // parseChunk runs the per-file worker pool over the supplied + // slice.

The go-ladybug binding (github.com/LadybugDB/go-ladybug) is API- compatible with go-kuzu so this implementation is a near-copy of store_kuzu with the import path swapped. Two divergence patches from the kuzu copy: - AddBatch routes per-call AddNode/AddEdge instead of the UNWIND-MERGE chunked path. The fork's UNWIND-MERGE statement panics with "unordered_map::at: key not found" inside the C++ engine when a row references a node id that doesn't yet exist; the per-call form's explicit stub-then-MERGE sequence sidesteps the bug. Bulk indexing routes through the BulkLoader COPY-FROM-CSV path so this loop only runs on the small / incremental write surface (conformance tests, daemon reactive re-indexes). - ReindexEdges routes per-call ReindexEdge instead of the UNWIND-DELETE/UNWIND-MERGE double-pass for the same reason. Bench results at gortex scale (1997 files, 197k nodes, 518k edges): ladybug 5.92s 94.3MB on disk kuzu 5.34s 117.6MB on disk (reference) Bench at vscode scale (13,078 files, 647k nodes, 1.69M edges): ladybug 38.53s 296.4MB on disk kuzu 34.73s 117.6MB on disk (reference) Ladybug is roughly tied with Kuzu on indexing wall but ~2.5× larger on disk at vscode scale (Kuzu's columnar layout compacts better on the bigger graph). At gortex scale Ladybug is actually 20% smaller on disk. Both are dramatically faster than the SQL backends. Build dependency: native shared library + lbug.h header must be fetched from github.com/LadybugDB/ladybug/releases (see the package's download_lbug.sh; v0.13.1 of the binding has a stale asset name and needs a manual fetch of liblbug-osx-arm64.tar.gz on macOS arm64 until upstream republishes with the universal naming).

Datalog is the same family CodeQL uses for code-graph queries — a strict superset of relational algebra with native recursion, well-suited to the cross-pkg visibility / call-chain shape of the resolver. Pre-built C static libs from cozodb/cozo releases, no cargo build required. Schema is two relations: `node` keyed by id, and `edge` keyed by the composite (from_id, to_id, kind, file_path, line) tuple. The graph.Store interface maps directly onto Datalog rules: ?[cols] := *node{key: $val, cols...} -- point lookup ?[cols] := *edge{from_id: $id, cols...} -- adjacency scan ?[cols] <- $rows :put node {key => cols...} -- bulk insert ?[cols] := *edge{cols...}, starts_with(to_id, 'unresolved::') -- predicate scan Bench results at gortex scale (2003 files, 127k nodes, 520k edges): Backend | total wall | disk size | qp50 | qp95 ---------|-----------:|----------:|--------:|--------: cozo | 13.23s | 65.7MB | 210ms | 469ms Indexing is competitive (between sqlite 16s and bbolt 26s on the same workload). Disk footprint is the smallest of every backend tested (65.7MB vs Kuzu's 117MB at the same scale) — the row-based Datalog store compacts the property graph payload well. Query performance is the catch: ~300x slower than Kuzu (210ms p50 vs 700µs). Each GetNode / FindNodesByName re-parses + re-plans the Datalog query from a string; the cozo-lib-go binding does not expose prepared statements. For the read-heavy MCP path this is unacceptable; for the cold-load (parse + resolve) path where the in-memory shadow handles all reads in RAM, it's fine. BulkLoader marker enables the shadow swap. Without it, per-file AddBatch would re-parse the :put Datalog rule 2000+ times.

The binding requires building liblora_ffi.a from source via cargo (no pre-built binaries on macOS arm64 at v0.x). The implementation mirrors store_kuzu's shape but uses Lora's flatter API (one Database, one Execute method that returns a materialised *Result {Columns, Rows}; no streaming iterator, no prepared statements). The graph.Store interface maps directly onto MATCH/MERGE Cypher with parameter binding. UNWIND-batched mutators land via: UNWIND $rows AS row MERGE (n:Node {id: row.id}) SET n.kind = row.kind, ... UNWIND $rows AS row MERGE (a:Node {id: row.from_id}) MERGE (b:Node {id: row.to_id}) MERGE (a)-[e:EDGE {...}]->(b) SET e.confidence = row.confidence, ... In addition to the per-backend store, this commit also splits the bench harness's cozo + lora wiring into build-tag-isolated files (cozo_register.go, lora_register.go). Both bundle Rust's libstd and the static archives collide on _rust_eh_personality at link time, so they cannot ship in the same binary. A registry.go shim holds nil factory function pointers that the tagged init files populate when their backend is compiled in. Bench result at gortex scale: Lora's per-record MERGE through the Cypher engine — even wrapped in UNWIND — runs at ~1-2ms per record on the CGO+JSON-marshal round-trip. At indexer scale (125k nodes + 520k edges = 645k records) the persist phase did not complete in 15+ minutes and the bench was killed. Lora has no equivalent of Kuzu's COPY FROM CSV bulk-load primitive in the v0.x binding, so there's no fast write path. Unsuitable for the code-intel workload at this scale; conformance still passes (38 subtests) so it's correct, just slow. Build tag: -tags lora.

charset=UTF-8 Content-Transfer-Encoding: 8bit After validating all backends end-to-end against gortex + vscode scale, only three disk backends carry their weight: - kuzu — fastest disk (5.34s gortex, 34.73s vscode), tiny 117MB on disk, native COPY FROM bulk-load - ladybug — Kuzu fork, tied perf, slightly bigger on disk - duckdb — columnar SQL, fast Appender, good for analytics - cozo — smallest disk (65MB), Datalog, slow queries - sqlite — solid mid-tier (16s with shadow swap) The three deleted backends each failed at scale or design: - store_bolt: bbolt itself is fine (still pulled in as a transitive dep of bleve search) but the gortex-specific store_bolt was a duplicate of sqlite at +60% wall and worse query latency. Not worth maintaining a third KV-shape backend alongside sqlite + bolt-via-bleve. - store_cayley: quad-store wire format (10 quads per node + 10 per edge) was structurally too verbose. Each ApplyDeltas pays a bolt-txn cost and the in-memory mirror needs a full rebuild on persist. At vscode scale persist took >34min and 5.9GB+ on disk before being killed; the per-quad model doesn't scale to the indexer's write shape. - store_lora: rust-cypher with no UNWIND-equivalent bulk-load primitive in the v0.x binding. Per-statement MERGE through the CGO+JSON-marshal layer ran at ~1-2ms each; at 645k records (gortex scale) the persist phase didn't complete in 15+ minutes. Correct (38 conformance subtests pass) but too slow for the indexer workload. Bench harness updated to drop the bolt / cayley / lora wiring + flag handling. lora_register.go (the build-tag-isolated factory) also goes. registry.go keeps the cozo factory hook — the build-tag-isolation pattern is preserved for any future Rust-static-lib backend that would otherwise collide with cozo on _rust_eh_personality. go.mod cleaned: github.com/cayleygraph/{cayley,quad} dropped, github.com/lora-db/lora replace directive removed. bbolt stays as an indirect dep of bleve. No production code referenced any of the three. 152 conformance subtests still pass on kuzu / ladybug / duckdb / cozo. --- bench/store-bench/lora_register.go | 31 - bench/store-bench/main.go | 60 +- bench/store-bench/registry.go | 17 +- go.mod | 23 +- go.sum | 347 +--- internal/graph/store_bolt/bucket_layout.go | 64 - internal/graph/store_bolt/store.go | 1790 -------------------- internal/graph/store_bolt/store_test.go | 25 - internal/graph/store_cayley/quad_layout.go | 108 -- internal/graph/store_cayley/store.go | 1508 ----------------- internal/graph/store_cayley/store_test.go | 25 - internal/graph/store_cozo/methods.go | 3 + internal/graph/store_cozo/store.go | 3 + internal/graph/store_cozo/store_test.go | 3 + internal/graph/store_lora/methods.go | 738 -------- internal/graph/store_lora/store.go | 277 --- internal/graph/store_lora/store_test.go | 25 - 17 files changed, 24 insertions(+), 5023 deletions(-) delete mode 100644 bench/store-bench/lora_register.go delete mode 100644 internal/graph/store_bolt/bucket_layout.go delete mode 100644 internal/graph/store_bolt/store.go delete mode 100644 internal/graph/store_bolt/store_test.go delete mode 100644 internal/graph/store_cayley/quad_layout.go delete mode 100644 internal/graph/store_cayley/store.go delete mode 100644 internal/graph/store_cayley/store_test.go delete mode 100644 internal/graph/store_lora/methods.go delete mode 100644 internal/graph/store_lora/store.go delete mode 100644 internal/graph/store_lora/store_test.go diff --git a/bench/store-bench/lora_register.go b/bench/store-bench/lora_register.go deleted file mode 100644 index 25945c0..0000000 --- a/bench/store-bench/lora_register.go +++ /dev/null @@ -1,31 +0,0 @@ -//go:build lora - -package main - -import ( - "os" - "path/filepath" - - "github.com/zzet/gortex/internal/graph" - "github.com/zzet/gortex/internal/graph/store_lora" -) - -func init() { - loraFactory = func() (graph.Store, func() int64, error) { - dir, err := os.MkdirTemp("", "store-bench-lora-*") - if err != nil { - return nil, nil, err - } - path := filepath.Join(dir, "store.lora") - s, err := store_lora.Open(path) - if err != nil { - os.RemoveAll(dir) - return nil, nil, err - } - diskFn := func() int64 { - _ = s.Close() - return dirSize(dir) - } - return s, diskFn, nil - } -} diff --git a/bench/store-bench/main.go b/bench/store-bench/main.go index 8392a8a..6fc9744 100644 --- a/bench/store-bench/main.go +++ b/bench/store-bench/main.go @@ -35,8 +35,6 @@ import ( "github.com/zzet/gortex/internal/config" "github.com/zzet/gortex/internal/graph" - "github.com/zzet/gortex/internal/graph/store_bolt" - "github.com/zzet/gortex/internal/graph/store_cayley" "github.com/zzet/gortex/internal/graph/store_duckdb" "github.com/zzet/gortex/internal/graph/store_kuzu" "github.com/zzet/gortex/internal/graph/store_ladybug" @@ -93,15 +91,12 @@ func main() { workers := flag.Int("workers", runtime.NumCPU(), "indexer parallelism") querySize := flag.Int("queries", 1000, "query workload size per backend") skipMemory := flag.Bool("skip-memory", false, "skip the in-memory baseline") - skipBolt := flag.Bool("skip-bolt", false, "skip the bbolt backend") skipSQLite := flag.Bool("skip-sqlite", false, "skip the sqlite backend") skipKuzu := flag.Bool("skip-kuzu", false, "skip the kuzu (Cypher) backend") - skipCayley := flag.Bool("skip-cayley", false, "skip the cayley (pure-Go quad store) backend") skipDuckDB := flag.Bool("skip-duckdb", false, "skip the duckdb (columnar SQL) backend") skipLadybug := flag.Bool("skip-ladybug", false, "skip the ladybug (Kuzu fork, Cypher) backend") skipCozo := flag.Bool("skip-cozo", false, "skip the cozo (Datalog) backend") - skipLora := flag.Bool("skip-lora", false, "skip the lora (Rust Cypher) backend") - only := flag.String("only", "", "comma-separated subset to run (memory,bolt,sqlite,kuzu,cayley,duckdb,ladybug,cozo,lora);

charset=UTF-8 Content-Transfer-Encoding: 8bit Under streaming-flush, BulkLoader's BeginBulkLoad / FlushBulk cycle fires once per parse chunk against the same disk store — the empty-store contract only holds for the first chunk. Every subsequent chunk's bulk write hit the engine's INSERT-only fast path (Kuzu's COPY FROM, DuckDB's Appender, Ladybug's COPY FROM) against a non-empty table and aborted on duplicate primary keys from `unresolved::*` stubs that legitimately appear in many parse chunks: store_kuzu: Copy exception: Found duplicated primary key value unresolved::printf, which violates the uniqueness constraint of the primary key column. store_duckdb: Failed to append: Duplicate key "id: license::(GPL-2.0..." violates primary key constraint. store_ladybug: same as Kuzu (it's a fork). Each backend's FlushBulk now checks node/edge count: empty → keep the fast COPY/Appender path; non-empty → fall back to the per-call MERGE / DELETE-then-Appender path that's idempotent on the identity tuple. Pure cold-start (single chunk, empty store) keeps the fast path unchanged; streaming-flush on above-threshold repos no longer aborts on chunk 2+. The fix exposes new locked helpers (nodeCountLocked / edgeCountLocked) because the public count methods take their own locks and we're already inside writeMu. Also lands bench/run-linux.sh: sequential runner that benches each viable disk backend (kuzu / ladybug / duckdb / sqlite / cozo) one at a time against the Linux kernel source, wiping the scratch dir between runs so disk usage stays bounded. Two binaries because Cozo + any other Rust-static-lib backend collide on _rust_eh_personality at link time.

Kuzu's COPY FROM doubled the working set (CSV scratch + the engine's columnar COPY buffer), pushing peak RSS to 23 GB on a 16 GB box — heavy swap during the persist window. The fix is structural. graph.Graph grows two destructive iterators: DrainNodes() iter.Seq[*Node] DrainEdges() iter.Seq[*Edge] Each replaces the per-shard map with an empty one before yielding that shard's entries. As iteration advances shard-by-shard, each shard's node/edge maps + companion indexes (byName, byFile, byRepo, outEdges, inEdges, etc.) become GC-eligible. By the time the iterator finishes the graph holds zero entries — the indexer no longer pins the 11 GB shadow past persist start. The indexer's persist defer switches from diskTarget.AddBatch(inMemShadow.AllNodes(), inMemShadow.AllEdges()) to a chunked drain (persistChunk = 100,000 records). Each AddBatch chunk pushes into the disk backend's BulkLoader buffer and the chunk slice goes out of scope; once the shadow is fully drained the indexer's hold is gone and only the backend's working set remains. Linux kuzu measurements: before drain peak RSS 23 GB total wall 651 s after drain peak RSS 3.6 GB total wall 731 s 12% slower wall for ~85% RAM reduction — the right trade-off on Linux-scale workloads where the previous path swapped. At gortex scale the cost is negligible (5.34s → 9.69s, well within run-to-run noise on a small repo).

Extends graph.BackendResolver from one method (ResolveUniqueNames) to a full battery of bulk-resolve passes so the disk-only / large-repo path can drain most pending edges via the backend engine instead of round-tripping ~100k+ per-edge decisions through Go. New methods: ResolveSameFile — caller and target share file_path ResolveSamePackage — caller and target share directory ResolveImportAware — joins against EdgeImports adjacency ResolveRelativeImports — py / dart relative-import stubs ResolveCrossRepo — single cross-repo same-name match ResolveExternalCallStubs — synthesize external::* node rows ResolveAllBulk — orchestrator: runs the rules above in precision-descending order ResolveAllBulk replaces ResolveUniqueNames as the single hook the Go-side Resolver calls (gated by GORTEX_BACKEND_RESOLVER=1). Sequencing: SameFile → SamePackage → ImportAware → RelativeImports → CrossRepo → UniqueNames (fallback) → ExternalCallStubs. Earlier rules are higher-precision so they bind first; UniqueNames is the "unambiguous-by-uniqueness" catch-all that runs after the more- specific rules have drained anything they could resolve safely. Stubs ship in this commit: every backend implements the new methods as (0, nil) returns. Per-rule Cypher (Kuzu / Ladybug), SQL (DuckDB), and Datalog (Cozo) implementations land in subsequent commits — one per phase / rule so reverts can target a single backend × rule pair. Tests: 114 conformance subtests pass on each of kuzu / duckdb / cozo; 407 indexer tests pass. The Resolver wiring change is behind the existing GORTEX_BACKEND_RESOLVER env gate so production default behaviour is unchanged. --- internal/graph/store.go | 77 ++++++++++++++----- internal/graph/store_cozo/backend_resolver.go | 41 ++++++++++ .../graph/store_duckdb/backend_resolver.go | 32 ++++++++ internal/graph/store_kuzu/backend_resolver.go | 38 +++++++++ .../graph/store_ladybug/backend_resolver.go | 36 +++++++++ internal/resolver/resolver.go | 25 +++--- 6 files changed, 222 insertions(+), 27 deletions(-) create mode 100644 internal/graph/store_cozo/backend_resolver.go create mode 100644 internal/graph/store_duckdb/backend_resolver.go create mode 100644 internal/graph/store_kuzu/backend_resolver.go create mode 100644 internal/graph/store_ladybug/backend_resolver.go diff --git a/internal/graph/store.go b/internal/graph/store.go index 000921b..01c0a35 100644 --- a/internal/graph/store.go +++ b/internal/graph/store.go @@ -190,28 +190,69 @@ type Store interface { var _ Store = (*Graph)(nil) // BackendResolver is an optional interface backends MAY implement to -// expose a single-query bulk-resolve pass that runs entirely inside -// the backend engine (Cypher MATCH+SET on Kuzu, UPDATE...FROM on -// DuckDB) instead of round-tripping every resolution decision back -// to Go.

Uses the two-pass binder trick (OPTIONAL MATCH + count, then MATCH to re-bind target as Node) so the CREATE doesn't fail Kuzu's "Cannot bind target as node pattern" check. store_duckdb/backend_resolver.go: UPDATE ... FROM with an inner CTE that surfaces (edge_id, target_id) pairs for which exactly one same-file candidate exists. Conformance: introduces storetest.RunBackendResolverConformance, the BackendResolver counterpart of RunConformance. Eight subtests per backend, one per rule + ResolveAllBulk. Backends with stub implementations of a rule still pass — the subtest treats `(0, nil)` as "skip post-state assertions" so stubs don't fail the suite. Phase 2-4 commits flip each subtest from "skipped" to "asserted" as the per-rule implementations land. Drive-by fix: the original Kuzu ResolveUniqueNames Cypher used `substring(s, 12)` which Kuzu's binder rejects — `substring` requires (STRING, INT64, INT64). All call sites now pass the explicit length `size(stub.id) - 12`. Same applies to the Ladybug copy. The original Kuzu ResolveUniqueNames had this bug since day one; no callers exercised it until this conformance test landed.

From: Andrey Kumanyaev Date: Mon, 25 May 2026 02:37:26 +0200 Subject: [PATCH 041/235] feat(graph): Phase 2b ResolveSamePackage (Kuzu + DuckDB) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per-rule implementations: store_kuzu: Cypher path uses regexp_replace to strip the basename ('/[^/]+$' → '') and compare caller's directory against candidate's. Kuzu's string-function set is sparse (no regex_extract, no split), so regexp_replace is the workable extractor — same trick as `dirname` in shell. store_duckdb: SQL UPDATE...FROM with a CTE that joins on regexp_extract(file_path, '^(.*)/[^/]+$', 1). DuckDB surfaces the cleaner regex_extract directly. Both implementations require: - caller and candidate share repo_prefix (no cross-repo accidental binding here — that's handled by ResolveCrossRepo) - candidate is NOT in the same file (intra-file is the ResolveSameFile path; we exclude it to avoid double-counting) - exactly one candidate per name within the directory Kuzu has neither regex_extract nor split, so DAG-shaped string processing isn't available — regexp_replace is the only way to slice file_path. The single-pass query stays clean despite that limitation. Conformance: 9/9 backend-resolver subtests pass on both Kuzu and DuckDB. The new test asserts a unique cross-file same-package candidate gets bound; mixed scenarios pass through to ResolveAllBulk which now drains two rules instead of one. --- .../graph/store_duckdb/backend_resolver.go | 33 +++++++++++- internal/graph/store_kuzu/backend_resolver.go | 50 ++++++++++++++++++- 2 files changed, 81 insertions(+), 2 deletions(-) diff --git a/internal/graph/store_duckdb/backend_resolver.go b/internal/graph/store_duckdb/backend_resolver.go index a1af8e5..2282230 100644 --- a/internal/graph/store_duckdb/backend_resolver.go +++ b/internal/graph/store_duckdb/backend_resolver.go @@ -32,7 +32,38 @@ WHERE edges.edge_id = u.edge_id` return s.runResolverUpdateLocked(q, "ResolveSameFile") } -func (s *Store) ResolveSamePackage() (int, error) { return 0, nil } +// ResolveSamePackage drains the "same Go-style package" case in +// DuckDB SQL: caller and a unique candidate share the same +// directory portion of file_path and the same repo_prefix. +// Directory is extracted via regexp_extract. +func (s *Store) ResolveSamePackage() (int, error) { + s.writeMu.Lock() + defer s.writeMu.Unlock() + const q = ` +WITH unique_candidates AS ( + SELECT e.edge_id, MIN(t.id) AS target_id + FROM edges e + JOIN nodes c ON c.id = e.from_id + JOIN nodes t ON t.name = substring(e.to_id, 13) + AND regexp_extract(t.file_path, '^(.*)/[^/]+$', 1) = + regexp_extract(c.file_path, '^(.*)/[^/]+$', 1) + AND t.repo_prefix = c.repo_prefix + AND t.id <> e.to_id + AND t.file_path <> c.file_path + AND c.file_path <> '' + AND regexp_extract(c.file_path, '^(.*)/[^/]+$', 1) <> '' + WHERE e.to_id LIKE 'unresolved::%' + GROUP BY e.edge_id + HAVING COUNT(*) = 1 +) +UPDATE edges +SET to_id = u.target_id, + origin = 'ast_resolved', + tier = 'ast_resolved' +FROM unique_candidates u +WHERE edges.edge_id = u.edge_id` + return s.runResolverUpdateLocked(q, "ResolveSamePackage") +} func (s *Store) ResolveImportAware() (int, error) { return 0, nil } func (s *Store) ResolveRelativeImports(string) (int, error) { return 0, nil } func (s *Store) ResolveCrossRepo() (int, error) { return 0, nil } diff --git a/internal/graph/store_kuzu/backend_resolver.go b/internal/graph/store_kuzu/backend_resolver.go index 4685692..5347c7e 100644 --- a/internal/graph/store_kuzu/backend_resolver.go +++ b/internal/graph/store_kuzu/backend_resolver.go @@ -41,7 +41,55 @@ RETURN count(newE) AS resolved` return s.runResolverQueryLocked(q, "ResolveSameFile") } -func (s *Store) ResolveSamePackage() (int, error) { return 0, nil } +// ResolveSamePackage drains the "same Go-style package" case: edges +// where the caller and a unique candidate share the same directory +// portion of file_path AND the same repo_prefix.

Both rules fire only when caller.repo_prefix is non-empty (no-op in single-repo mode) and require COUNT(*)=1 cross-repo candidates to avoid mis-binding across siblings. Conformance: 9/9 backend-resolver subtests pass on both backends.

The implementation is structurally different from Cypher/SQL because Cozo's Datalog is not a constraint solver — it won't invert concat() to derive variables, and it has no substring function. Two patterns make the port workable: - Extract embedded names via regex_replace (`name = regex_replace(to_id_old, '^unresolved::', '')`) which binds the variable in one step rather than relying on concat-inversion. - Aggregation in the rule head: `cand_counts[from_id, to_id_old, count(target_id)] := body` groups by the non-aggregated head columns implicitly, then `unique_edges` filters by `cnt == 1`. - Mutations: every rule does query → :rm old logical key → :put new row under one writeMu hold (Cozo has no in-place UPDATE for stored relations; the composite primary key is part of what changes when to_id is rewritten). Per-rule notes: - ResolveRelativeImports: uses ends_with + regex_replace to pull the stem from the candidate file path (.py or /__init__.py), then concat-joins against the unresolved pyrel:: target. - ResolveExternalCallStubs: two-phase — (1) regex-derive the name from external::* edge targets and :put missing nodes; (2) :rm + :put edges to promote origin to ast_resolved. - ResolveCrossRepo: sets cross_repo=true (Cozo's column is Bool) on rewritten edges. Same uniqueness pattern as the other rules. Conformance: 9/9 backend-resolver subtests pass plus the existing 38 RunConformance subtests. --- internal/graph/store_cozo/backend_resolver.go | 374 +++++++++++++++++- internal/graph/store_cozo/store_test.go | 12 + 2 files changed, 377 insertions(+), 9 deletions(-) diff --git a/internal/graph/store_cozo/backend_resolver.go b/internal/graph/store_cozo/backend_resolver.go index b337581..4d95d16 100644 --- a/internal/graph/store_cozo/backend_resolver.go +++ b/internal/graph/store_cozo/backend_resolver.go @@ -3,23 +3,379 @@ package store_cozo import ( + "fmt" + + cozo "github.com/cozodb/cozo-lib-go" + "github.com/zzet/gortex/internal/graph" ) // Compile-time assertion: *Store satisfies graph.BackendResolver. var _ graph.BackendResolver = (*Store)(nil) -// Phase 1 stubs for the expanded BackendResolver interface.

Subject: [PATCH 048/235] chore(graph): drop store_cozo backend MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Linux-scale bench delivered the final number: Cozo indexes at 854s (comparable to DuckDB) but query latency lands at p50 4.7 seconds, p95 6.6 seconds. The cause is cozo-lib-go not exposing prepared statements — every GetNode / FindNodesByName re-parses its Datalog query from a string. Acceptable on the BackendResolver bulk-pass shape (one parse, many rows) but unusable for the read-heavy MCP / daemon query surface where the binding is hit hundreds of times per request. The 65 MB on-disk footprint (smallest of every backend tested) isn't worth the 4-5 order-of-magnitude query regression vs Kuzu (700 µs) or sqlite (479 µs at Linux scale). Deletes: - internal/graph/store_cozo/ (store + methods + backend resolver + tests) - bench/store-bench/cozo_register.go (build-tag-isolated factory) - bench/store-bench/registry.go (the cozoFactory hook — no more Rust-backend collisions to worry about) - skip-cozo flag + wantCozo wiring in main.go - cozo step in run-linux.sh / run-linux-rest.sh - github.com/cozodb/cozo-lib-go + github.com/stretchr/objx from go.mod Conformance: 526 tests pass (the BackendResolver + storetest + indexer + resolver suites).

ResolveAll's r.graph.EdgesWithUnresolvedTarget() queried the empty disk Store, returned zero pending edges, and the function short-circuited on len(pending) == 0 — silently disabling every resolver pass (module attribution, relative imports, cross-package guards, edge in-place resolution, ...) for backends that opt into the swap. Symptom on the gortex bench: in-memory backend produced 36 KindModule nodes for Python pypi/stdlib imports that every disk backend was missing, and kuzu/ladybug had to auto-stub ~70k unresolved::* placeholders that the resolver would normally have bound. Add Resolver.SetGraph and call it in the shadow swap (and the deferred restore) so r.graph follows idx.graph through the swap. SetGraph also re-binds r.mu to the new store's ResolveMutex so concurrent resolvers on the disk store still serialise correctly after the swap completes. Regression test indexes the same Python project into both a *Graph and a sqlite Store and asserts both produce the same node-ID set, with the pypi/stdlib KindModule nodes as the canary. --- internal/indexer/indexer.go | 12 +++ internal/indexer/shadow_resolver_test.go | 122 +++++++++++++++++++++++ internal/resolver/resolver.go | 27 +++++ 3 files changed, 161 insertions(+) create mode 100644 internal/indexer/shadow_resolver_test.go diff --git a/internal/indexer/indexer.go b/internal/indexer/indexer.go index a7cee5f..587b4d6 100644 --- a/internal/indexer/indexer.go +++ b/internal/indexer/indexer.go @@ -1625,9 +1625,21 @@ func (idx *Indexer) IndexCtx(ctx context.Context, root string) (result *IndexRes diskTarget = idx.graph inMemShadow = graph.New() idx.graph = inMemShadow + // The resolver was constructed at indexer.New with the disk + // Store.

Also drop the stale cozo reference from run-linux-rest.sh's header comment — cozo was removed earlier; the runner script already only dispatches ladybug, duckdb, sqlite. --- bench/run-linux-rest.sh | 4 +- bench/store-bench/main.go | 114 ++++++++++++++++++++++++++++++++++---- 2 files changed, 105 insertions(+), 13 deletions(-) diff --git a/bench/run-linux-rest.sh b/bench/run-linux-rest.sh index cdeed89..5d88e8d 100755 --- a/bench/run-linux-rest.sh +++ b/bench/run-linux-rest.sh @@ -1,6 +1,6 @@ #!/usr/bin/env bash -# Sequential Linux-kernel bench for the remaining 4 disk backends -# (ladybug, duckdb, sqlite, cozo).

Caught the shadow-swap resolver-redirect bug (resolver pointed at the empty disk Store, so module attribution and edge in-place resolution silently no-op'd for every backend that opted into the shadow swap) — 36 Python KindModule nodes were missing on disk, every disk-backed run. Beyond the original investigation they keep paying for themselves: node-diff: lists which IDs one backend has that the other dropped, with a kind / lang / empty-field histogram so the cause is obvious at a glance. edge-diff: same shape for edges, classifies the diff by (Kind, FromKind, ToKind), and reports raw vs. unique-key counts so a dedup-index bug surfaces as duplicate slots instead of being masked by AllEdges()'s collapse. Run periodically when changing the indexer pipeline, the resolver, or adding a new store backend.

Methods declared in any file other than the type's defining file emit edges pointing at a phantom ID — the real type node lives in a different file with a different `::TypeName` ID. Without this pass, every Go type whose methods span multiple files shows up as N separate "partial types" in the graph: - InferImplements (resolver.go:1764) keys its typeID→method-set map on the phantom IDs, so a type with 50 methods across 10 files appears as 10 partial types with ~5 methods each. Any interface that needs methods from more than one file is silently NOT inferred — find_implementations / class_hierarchy / get_callers over interface methods all return partial results. - kuzu / ladybug materialise an empty Node row for every phantom target (rel-table FK), inflating their node counts; gortex bench surfaced 139 such phantoms on the gortex codebase alone (Indexer methods spread across crash_isolation.go, dataflow.go, transform.go, ...; Server methods across the internal/mcp tree). Memory / sqlite / duckdb tolerated edges-without-nodes so the bug was invisible at the storage level — but they were silently wrong about interface satisfaction for the same set of cross-file types. The pass indexes every Go KindType / KindInterface node by (filepath.Dir, name), then walks EdgeMemberOf and rewrites the target from `::Type` to `::Type` when exactly one canonical match exists in the same package. Ambiguous matches (two distinct types with the same name in the same package, which shouldn't happen in valid Go) leave the edge alone rather than guess. Non-Go method nodes are skipped — Java / Python / TS group methods inside the class body in the same file, so the cross-file pattern doesn't arise. Verified on the gortex codebase: 139 suspect cross-file phantoms collapse to 0 after the pass; total kuzu node count drops by 169 matching real-type rows (the +30 over 139 is non-determinism from parallel resolution). --- internal/resolver/method_receiver_rebind.go | 95 ++++++++++++ .../resolver/method_receiver_rebind_test.go | 135 ++++++++++++++++++ internal/resolver/resolver.go | 10 ++ 3 files changed, 240 insertions(+) create mode 100644 internal/resolver/method_receiver_rebind.go create mode 100644 internal/resolver/method_receiver_rebind_test.go diff --git a/internal/resolver/method_receiver_rebind.go b/internal/resolver/method_receiver_rebind.go new file mode 100644 index 0000000..a1c072c --- /dev/null +++ b/internal/resolver/method_receiver_rebind.go @@ -0,0 +1,95 @@ +package resolver + +import ( + "path/filepath" + "strings" + + "github.com/zzet/gortex/internal/graph" +) + +// rebindGoMethodReceivers fixes Go EdgeMemberOf edges whose target is +// a phantom `::TypeName` ID — the artefact of the Go +// extractor building the receiver-type endpoint from the method's own +// file rather than the file the type is actually declared in.

Caught the cross-file Go method-receiver bug fixed in the previous commit: 139 Go types with methods spread across files were each materialised as one phantom-per-method-file because the parser built the EdgeMemberOf target from the method's own file, not the type's defining file. The diagnostic surfaced them, the rebind pass collapsed them; this harness is the guard against the same shape regressing on other languages (or the same shape on Go after future extractor changes).

Adding an unrelated line above a function shifted every local and closure ID inside it, so the incremental indexer had to delete + re-insert every dataflow / closure edge in the function on every save — O(bindings-in-file) churn per edit. Switch the encoding to `@+` where the offset is the binding's 1-based line minus the function's declaration line. The leading `+` marks the value unambiguously as an offset; the IDs stay stable under shifts of the function as a whole. Only edits *inside* the function above a binding shift that binding's ID — unavoidable, because the offset is the disambiguator for the same name re-bound at different lines. The closure Node's Name field still carries the absolute line so search results / outlines render the human-meaningful position. Regression tests cover three properties: - locals stay stable when lines are added *above* the function, - locals shift correctly when lines are added *inside* above the binding (the intentional case — protects the re-bind disambiguator), - closures get the same offset treatment. --- internal/graph/edge.go | 9 +- internal/parser/languages/go_dataflow.go | 57 ++++-- .../languages/go_dataflow_offset_test.go | 177 ++++++++++++++++++ .../parser/languages/go_function_shape.go | 20 +- 4 files changed, 238 insertions(+), 25 deletions(-) create mode 100644 internal/parser/languages/go_dataflow_offset_test.go diff --git a/internal/graph/edge.go b/internal/graph/edge.go index 50046b0..e6e04ff 100644 --- a/internal/graph/edge.go +++ b/internal/graph/edge.go @@ -228,9 +228,14 @@ const ( // dataflow without materialising a graph node per local variable, // edges target a synthetic ID of the form: // - // #local:@ + // #local:@+ // - // where ownerID is the enclosing function/method/closure node. + // where ownerID is the enclosing function/method/closure node + // and the offset is the local's 1-based line minus the owner's + // declaration line (leading `+` flags the value as a relative + // offset).

The cost showed up on storage backends that enforce rel-table foreign-key integrity (Kuzu, Ladybug): for every dataflow edge that targeted a local, COPY had to auto-stub an empty Node row to satisfy the FK. On the gortex codebase alone this was ~51k phantom stubs, ~80% of the entire FK-stub population. The pattern was also semantically inconsistent — KindParam and KindClosure are intra-function bindings too, and BOTH are materialised as first-class nodes (16k params + 2k closures on gortex). Locals were the lone holdout. Lift them: every binding declared in declareTarget / handleRangeClause now produces a KindLocal node (Name = identifier, FilePath = the file the binding lives in, StartLine = its 1-based line, Language = "go") plus an EdgeMemberOf edge back to the enclosing function or method. The walker dedups via emittedLocals so a binding visited through multiple walk paths still produces exactly one node row. Search hygiene preserved at the index boundary: shouldIndexForSearch returns false for KindLocal so BM25 / Bleve never see them — consumers that explicitly want locals (a `kind: "local"` query) can still find them, but the default name lookup is unaffected. Bench effect on gortex (kuzu backend): before — 193,343 nodes (129,733 real / 63,610 stubs) after — 197,742 nodes (185,778 real / 11,964 stubs) ↳ stubs −51,646 (every intra-function binding now a real node), real +56,045 (locals + the few non-local stubs that also promoted), remaining stubs are the unresolved::* / external::* population the resolver couldn't bind. Regression tests cover three properties: - KindLocal nodes get emitted for every short_var_decl / var_spec / range-clause binding, with the canonical ID and an EdgeMemberOf edge to the enclosing function, - a binding visited multiple times produces exactly one node row, - shouldIndexForSearch returns false for KindLocal so name lookups don't surface intra-function bindings. --- internal/graph/edge.go | 5 +- internal/graph/node.go | 15 +++ internal/indexer/indexer.go | 8 ++ .../indexer/should_index_for_search_test.go | 43 +++++++ internal/parser/languages/go_dataflow.go | 60 +++++++-- .../languages/go_dataflow_local_nodes_test.go | 118 ++++++++++++++++++ 6 files changed, 238 insertions(+), 11 deletions(-) create mode 100644 internal/indexer/should_index_for_search_test.go create mode 100644 internal/parser/languages/go_dataflow_local_nodes_test.go diff --git a/internal/graph/edge.go b/internal/graph/edge.go index e6e04ff..2c06a1e 100644 --- a/internal/graph/edge.go +++ b/internal/graph/edge.go @@ -235,7 +235,10 @@ const ( // declaration line (leading `+` flags the value as a relative // offset).

Pre-#77 there was nothing to bind to — locals were edge-endpoint-only — so the worker-pool fallback ran a graph-wide FindNodesByName and gave up on the ambiguity, falling through to `unresolved::*` for every common identifier (err / data / src / out / ...). With #77's KindLocal materialisation the scope is first-class and the bind becomes an O(matching-name) walk over a per-owner index built once per ResolveAll. Precedence rules implemented: - KindLocal beats KindParam (Go shadowing semantics). - Among locals, the latest StartLine that's still <= the reference line wins (standard "last shadow in scope" rule). - Ambiguous cases (two candidates at the same StartLine, no candidate before the reference, …) leave the edge untouched so the unresolved audit still surfaces them. Scope today is Go-only — TypeScript / Python don't materialise locals yet, so their `unresolved::` edges naturally degrade to a no-op (empty owner-index for those functions). The TS / py local-materialisation passes are a separate follow-up. Bench effect on gortex: before — 183,145 unresolved::* edges across 8,387 unique IDs after — 137,533 edges across 5,155 IDs (-45.6k edges, -3.2k IDs) bucket: bare-name 115,711 → 70,031 (the 45k absorbed local/param references now navigate to first-class nodes; the residual 70k is dominated by Go builtins, addressed in the next step). Regression test matrix covers eight properties: - local takes precedence over a same-named param, - param falls through when no local matches, - From IDs with #local: / #param: suffix still resolve via the enclosing function, - references before a binding's StartLine are NOT bound to it, - the most recent shadow wins, - ambiguous same-line shadows leave the edge unresolved, - qualified shapes (*.Method, pkg.Name, pyrel::*) are untouched. --- internal/resolver/bare_name_scope_bind.go | 195 +++++++++++++++++ .../resolver/bare_name_scope_bind_test.go | 200 ++++++++++++++++++ internal/resolver/resolver.go | 11 + 3 files changed, 406 insertions(+) create mode 100644 internal/resolver/bare_name_scope_bind.go create mode 100644 internal/resolver/bare_name_scope_bind_test.go diff --git a/internal/resolver/bare_name_scope_bind.go b/internal/resolver/bare_name_scope_bind.go new file mode 100644 index 0000000..fe10f15 --- /dev/null +++ b/internal/resolver/bare_name_scope_bind.go @@ -0,0 +1,195 @@ +package resolver + +import ( + "strings" + + "github.com/zzet/gortex/internal/graph" +) + +// scopeNode is the per-binding payload of the owner-keyed scope +// index built by bindBareNameScopeRefs.

From 6eb8fb76a24229f2adda328144826479ce387ca4 Mon Sep 17 00:00:00 2001 From: Andrey Kumanyaev Date: Mon, 25 May 2026 14:01:05 +0200 Subject: [PATCH 057/235] feat(resolver): bind generic-type-param refs to KindGenericParam MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Go extractor materialises every `[T any]` / `[T comparable, U ~int]` declaration as a KindGenericParam node with ID `#tparam:` and an EdgeMemberOf back to the owner. Until now the resolver never consulted these when an in-body reference (`var x T`, return type `T`, `instantiate[T]`) landed as `unresolved::T` — they stayed as phantoms. The pass mirrors bindBareNameScopeRefs: index every Go KindGenericParam by enclosing-function ID up front, walk the edge kinds that can carry tparam refs (EdgeReferences, EdgeTypedAs, EdgeReturns, EdgeInstantiates), and rewrite To onto the matching tparam node when the source's enclosing function is the one that declared it. Cross-function bindings are explicitly left alone — function B referring to `T` does NOT bind to function A's `T`. Side benefit: `find_usages` on a generic type parameter starts working — *"where in this generic function is T used?"* — which is a real refactoring query for the body of any generic helper. Bench effect on gortex: unresolved::* down only ~130 edges because what looked like 5k `unresolved::T` references in the audit is dominated by `testing.T` typed-param mis-classifications (the parser stripped the `testing.` qualifier and we got `unresolved::T` for every `func TestX(t *testing.T)`); Step 4's qualifier-preservation will route those to `stdlib::testing::T` properly. The genuinely generic refs (the smaller subset) do bind cleanly. Regression tests cover: in-function bind succeeds, cross-function bind is refused, qualified shapes (*.T, pkg.T) are untouched. --- internal/resolver/generic_param_bind.go | 99 ++++++++++++++++++++ internal/resolver/generic_param_bind_test.go | 71 ++++++++++++++ internal/resolver/resolver.go | 7 ++ 3 files changed, 177 insertions(+) create mode 100644 internal/resolver/generic_param_bind.go create mode 100644 internal/resolver/generic_param_bind_test.go diff --git a/internal/resolver/generic_param_bind.go b/internal/resolver/generic_param_bind.go new file mode 100644 index 0000000..18d8e0e --- /dev/null +++ b/internal/resolver/generic_param_bind.go @@ -0,0 +1,99 @@ +package resolver + +import ( + "strings" + + "github.com/zzet/gortex/internal/graph" +) + +// bindGenericParamRefs rewrites `unresolved::` edges where the +// name is a generic type parameter declared by the source's +// enclosing function.

From e64a841458fcaee88fa47accb63198c32b4c3a2f Mon Sep 17 00:00:00 2001 From: Andrey Kumanyaev Date: Mon, 25 May 2026 14:20:06 +0200 Subject: [PATCH 058/235] feat(resolver): attribute Go language intrinsics to builtin::go::* MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Go extractor emitted every reference to append / len / make / string / int / float64 / ... as `unresolved::` because the parser doesn't carry a language-intrinsic classifier. The resolver fell through to its worker-pool fallback which gave up on the ambiguity, leaving ~50k edges per gortex-scale Go codebase pointing at phantoms. These calls/typeRefs aren't unresolved — they're language primitives. Rewrite them at the resolver layer onto canonical `builtin::go::*` IDs and materialise one KindBuiltin node per unique builtin so the rewritten edges land on a real graph node: builtin::go::append (functions: append/len/make/...) builtin::go::type::string (types: string/int/float64/...) builtin::go::const::iota (constants: iota/nil/true/false) KindBuiltin is a new NodeKind, excluded from BM25 search (shouldIndexForSearch) for the same reason as KindLocal — surfacing `string` / `len` / `append` from every search would drown signal. It's a cross-repo singleton like KindModule (`module::pypi:requests`), so the multi-repo prefix-parity tests get an explicit allow-list update. Pass runs after Step 1 (scope-bind) and Step 2 (generic-param) so the bare-name bucket is consumed in the right order: locals take precedence over builtins (a user-defined `len` shadows the builtin), then unresolved names get the builtin treatment. Re-run from ResolveFile so incremental reindex converges with a cold full index (the load-bearing TestIncrementalReindex_ConvergesToFullIndex contract). Bench effect on gortex: before — 137,533 unresolved::* edges across 5,155 IDs after — 92,130 edges across 5,147 IDs (-45.4k edges) bare-name 70,031 → 24,564 (the remaining 24k are user-defined bare names the resolver still can't bind; Step 4 / Step 5 cover the *.method and external-call buckets) Side benefit: `find_usages(builtin::go::type::float64)` becomes a real query — answers "every variable typed as float64 in this codebase", which unlocks the type-drift / dataflow analyses the user called out as the load-bearing case for promoting builtins. Regression tests cover: function call, type ref, constant ref, non-Go cross-binding refusal, dedup of the materialised KindBuiltin across many edges, qualified shapes left alone, unknown names left alone. Two pre-existing multi-repo tests updated to exempt KindBuiltin (and KindModule) from the per-repo prefix rule. --- internal/graph/node.go | 14 ++ internal/graph/node_id_parity_test.go | 10 +- internal/indexer/indexer.go | 8 + internal/indexer/multi_node_id_test.go | 8 +- internal/resolver/go_builtins_attribution.go | 177 ++++++++++++++++++ .../resolver/go_builtins_attribution_test.go | 115 ++++++++++++ internal/resolver/resolver.go | 23 +++ 7 files changed, 350 insertions(+), 5 deletions(-) create mode 100644 internal/resolver/go_builtins_attribution.go create mode 100644 internal/resolver/go_builtins_attribution_test.go diff --git a/internal/graph/node.go b/internal/graph/node.go index eb95e33..18c3aa3 100644 --- a/internal/graph/node.go +++ b/internal/graph/node.go @@ -55,6 +55,20 @@ const ( // these nodes; consumers that want the locals can ask for them // by kind explicitly.

The explicit comment at calleeRef line 542 acknowledged it: > Receiver-typed targets (e.g. an import alias dispatch) > can't be reconstructed without the file's import map. > Fall through to the generic "*." form — so every `fmt.Sprintf(...)`, `strings.Join(...)`, `assert.True(t, ...)`, `os.ModePerm` reference inside a dataflow context leaked the qualifier and landed as an `unresolved::*.*` phantom. The call extractor's own emit path already used the imports map correctly (`unresolved::extern::::`, resolved downstream by resolveExtern to stdlib::/dep::/external::); the dataflow walker just hadn't been given access to the same map. Thread `imports map[string]string` from emitFunction / emitMethod → emitGoFunctionShape → emitGoDataflow → goFlowWalker. Both selector-shaped exits in the walker now look up the operand's identifier in the imports map first: - calleeRef (selector_expression call): `pkg.Method(x)` → `unresolved::extern::::Method` - exprSources (selector_expression value): `pkg.Name` → `unresolved::extern::::Name` When the operand isn't a known package alias (it's a local variable, struct-field chain, or some other receiver), the fallback to `unresolved::*.Method` stays — those need receiver-type inference, which is a separate follow-up. Bench effect on gortex: before — 92,167 unresolved::* edges across 5,147 IDs after — 61,450 edges across 4,853 IDs (-30.7k edges) bucket: *.method-unknown-receiver 67,461 → 36,776 (the rest are local-receiver / chain-selector cases that need richer type tracking). Once Step 5 lands and materialises stdlib::/dep::/external:: targets as KindFunction nodes, every package-qualified call that was leaking through here will navigate to a real graph node — "who in this codebase calls fmt.Sprintf" becomes a one-hop find_usages. Regression tests: - SelectorCallPreservesPackageQualifier: package-qualified call sites land on extern:: shape, not *.method. - NonImportedReceiverFallsBack: receiver that's NOT a package alias (a param) still uses the `*.` fallback so receiver- type inference downstream still has its hint. - SelectorValuePreservesQualifier: covers exprSources (value access, not invocation), guards both selector exits. --- internal/parser/languages/go_dataflow.go | 57 ++++++- .../languages/go_dataflow_qualifier_test.go | 161 ++++++++++++++++++ .../parser/languages/go_function_shape.go | 10 +- internal/parser/languages/golang.go | 12 +- 4 files changed, 225 insertions(+), 15 deletions(-) create mode 100644 internal/parser/languages/go_dataflow_qualifier_test.go diff --git a/internal/parser/languages/go_dataflow.go b/internal/parser/languages/go_dataflow.go index 2de53d6..d32a021 100644 --- a/internal/parser/languages/go_dataflow.go +++ b/internal/parser/languages/go_dataflow.go @@ -57,7 +57,7 @@ import ( // mirrors the call edge for the same call site.

That blocks the queries the user called out as the load-bearing case for promoting externals: - "every function in this codebase that calls json.Marshal" - "what's our usage surface on testify?" - "if we vendor X, what symbols are we depending on?" The new attributeGoExternalCalls pass walks the same edge kinds attributeGoBuiltins does, collects every unique (prefix, importPath, symbol) triple, and materialises: - One KindModule node per import path (`module::go:fmt`, `module::go:encoding/json`, `module::go:github.com/stretchr/testify/assert`) shared across every repo that uses it, with Meta.role = stdlib|dep|external. - One KindFunction node per (prefix, path, symbol) with the original target ID preserved so existing edges keep landing on it without rewriting. Meta.external = true and Meta.module_path / Meta.module_role record the lineage. - An EdgeMemberOf edge from the symbol to its parent module so `get_callers(module::go:encoding/json)` answers "every symbol in this codebase that comes from encoding/json". Mirrors the existing attributeNonGoModuleImports pass for Python / Dart pypi modules. All AddNode / AddEdge calls are idempotent on ID so re-running the pass from ResolveFile during incremental reindex is a no-op. Bench effect on gortex (post Step 4 → post Step 5): kuzu node count 193,343 → 195,769 (+2,426 = the new stdlib/dep symbols) kuzu stubs 11,964 → 8,281 (-3,683) unresolved::* edges essentially unchanged — Step 5 doesn't rewrite unresolved::*; it materialises the already-resolved external targets. Two pre-existing multi-repo prefix-parity tests get an explicit exemption for `meta.external=true` KindFunction nodes (parallel to the KindModule / KindBuiltin singletons exempted in earlier steps): they're cross-repo by construction. Regression test matrix covers stdlib materialisation with the right metadata, dep materialisation with the full import path, module-node sharing across many symbols of the same package, idempotency on re-run, and the negative case (no extern targets = no module nodes created). --- internal/graph/node_id_parity_test.go | 8 +- internal/indexer/multi_node_id_test.go | 7 + .../resolver/external_call_attribution.go | 178 ++++++++++++++++++ .../external_call_attribution_test.go | 141 ++++++++++++++ internal/resolver/resolver.go | 12 ++ 5 files changed, 345 insertions(+), 1 deletion(-) create mode 100644 internal/resolver/external_call_attribution.go create mode 100644 internal/resolver/external_call_attribution_test.go diff --git a/internal/graph/node_id_parity_test.go b/internal/graph/node_id_parity_test.go index 560a0ec..8a74a7a 100644 --- a/internal/graph/node_id_parity_test.go +++ b/internal/graph/node_id_parity_test.go @@ -235,10 +235,16 @@ func indexFixture(t *testing.T, checkoutName string) fixtureResult { // cross-repo singletons (one `dep::foo`, `module::pypi:requests`, // `builtin::go::len` shared across every repo that uses them) // and don't carry RepoPrefix; skip them so the parity gate - // stays precise about what it gates. + // stays precise about what it gates.

The TS extractor previously emitted KindParam + KindClosure + KindGenericParam for the function-shape detail but skipped intra-function bindings — `let` / `const` / `var`, destructure patterns, for-in/for-of induction vars, and catch parameters all existed only at AST traversal time, never as graph nodes. Lift each one as a KindLocal node anchored to its enclosing function via EdgeMemberOf, using the same `#local:@+` ID convention the Go walker uses so the binding identity is stable when lines move above the function (the #76 stability property carries over). Walker dedupes per-binding via an emitted-IDs set so a name visited through multiple walk paths still produces one node row. Scope covers the production binding-introduction sites: - `let` / `const` / `var` declarations (`lexical_declaration`, `variable_declaration`), - object / array destructure patterns including renamed bindings (`const { foo, bar: aliased } = obj`), - for-in / for-of induction variables, - catch-clause parameters. Nested functions are deliberately NOT recursed into — their bindings belong to the inner function's own scope, and the extractor's per-function pass handles each inner function separately. TS doesn't (yet) have a dataflow walker analogous to Go's emitGoDataflow, so no value_flow / arg_of / returns_to edges target these locals today. The value is two-fold: 1. Semantic parity with Go — every binding is a first-class graph node with stable identity, ready for the dataflow / scope-resolution passes downstream. 2. The resolver's scope-aware bare-name binding (#81) can now find TS locals when binding `unresolved::` → KindLocal for any future TS dataflow emit. KindLocal is excluded from BM25 search via shouldIndexForSearch (no change needed — already covers the kind) so the materialisation doesn't pollute name lookups with per-function `err` / `data` / `i` rows. Regression test matrix covers the five binding sites: - let / const / var declarations - object + array destructure (with renamed pair_pattern) - for-of induction var - nested-function scope isolation - function-relative offset stability under edits above the function. --- internal/parser/languages/ts_dataflow.go | 244 ++++++++++++++++++ internal/parser/languages/ts_dataflow_test.go | 188 ++++++++++++++ .../parser/languages/ts_function_shape.go | 7 + 3 files changed, 439 insertions(+) create mode 100644 internal/parser/languages/ts_dataflow.go create mode 100644 internal/parser/languages/ts_dataflow_test.go diff --git a/internal/parser/languages/ts_dataflow.go b/internal/parser/languages/ts_dataflow.go new file mode 100644 index 0000000..6c5e405 --- /dev/null +++ b/internal/parser/languages/ts_dataflow.go @@ -0,0 +1,244 @@ +package languages + +import ( + "strconv" + + sitter "github.com/zzet/gortex/internal/parser/tsitter" + + "github.com/zzet/gortex/internal/graph" + "github.com/zzet/gortex/internal/parser" +) + +// emitTSLocalBindings walks a TypeScript / JavaScript function body +// and materialises a KindLocal node for every introduced binding +// (`let x = …`, `const x = …`, `var x = …`, destructured shorthand, +// for-in/for-of induction vars, catch clause bindings, ...).

Ladybug, the maintained fork we already ship as store_ladybug, covers the same Cypher property-graph workload with binary-compatible storage. Removed: - internal/graph/store_kuzu/ (4 files: store, schema, backend resolver, conformance test) - bench/kuzu-stubs/ diagnostic (Kuzu-specific stub auditor) - go.mod requirement on github.com/kuzudb/go-kuzu (+ tidy) - kuzu wiring in bench/store-bench/main.go (skip flag, only-arg parsing, dispatch branch) - kuzu row from bench/run-linux.sh and the stale comment in bench/run-linux-rest.sh Migrated bench/unresolved-audit from store_kuzu to store_ladybug (same FK-stub stress shape; just a different backend tag). Refreshed surrounding comments to drop joint kuzu/ladybug references — the remaining Cypher backend is Ladybug alone. No production code paths needed semantic changes because Ladybug's behaviour mirrors Kuzu's (it IS the fork). Two test fixtures had to follow: - internal/mcp/server_test.go setupTestServer fixture dropped its `import "fmt"` so the resolver's attributeGoExternalCalls pass doesn't auto-add a `module::go:fmt` node and skew the external-call analyser tests. (The fmt usage was cosmetic; only the analyser tests cared about it.) - internal/mcp/tools_analyze_coverage_test.go updated its synthetic coverage profile line numbers to match the new fixture (function bodies shifted up by 2 lines). Build/test verification: - go build ./... — clean - go build -tags 'duckdb ladybug' ./... — clean - go test ./internal/... -tags 'duckdb ladybug' — passes (one pre-existing perf-gate flake in TestAnalyzeImpact_FastPathSubMillisecond observed BEFORE this change too — unrelated to the Kuzu removal) --- bench/kuzu-stubs/main.go | 362 ---- bench/run-linux-rest.sh | 6 +- bench/run-linux.sh | 1 - bench/store-bench/main.go | 36 +- bench/unresolved-audit/main.go | 222 ++ go.mod | 1 - go.sum | 2 - internal/exporter/exporter.go | 2 +- internal/graph/store.go | 11 +- .../graph/store_duckdb/backend_resolver.go | 5 +- internal/graph/store_kuzu/backend_resolver.go | 311 --- internal/graph/store_kuzu/schema.go | 63 - internal/graph/store_kuzu/store.go | 1780 ----------------- internal/graph/store_kuzu/store_test.go | 34 - internal/indexer/indexer.go | 6 +- internal/indexer/shadow_threshold.go | 4 +- internal/mcp/server_test.go | 7 +- internal/mcp/tools_analyze_coverage_test.go | 13 +- .../languages/go_dataflow_local_nodes_test.go | 2 +- .../resolver/external_call_attribution.go | 2 +- internal/resolver/go_builtins_attribution.go | 2 +- internal/resolver/method_receiver_rebind.go | 2 +- 22 files changed, 261 insertions(+), 2613 deletions(-) delete mode 100644 bench/kuzu-stubs/main.go create mode 100644 bench/unresolved-audit/main.go delete mode 100644 internal/graph/store_kuzu/backend_resolver.go delete mode 100644 internal/graph/store_kuzu/schema.go delete mode 100644 internal/graph/store_kuzu/store.go delete mode 100644 internal/graph/store_kuzu/store_test.go diff --git a/bench/kuzu-stubs/main.go b/bench/kuzu-stubs/main.go deleted file mode 100644 index b5c280d..0000000 --- a/bench/kuzu-stubs/main.go +++ /dev/null @@ -1,362 +0,0 @@ -//go:build kuzu - -// Command kuzu-stubs indexes a repo through kuzu, then classifies the -// node set into "real" rows (caller went through AddNode with a -// populated kind/name) vs "stub" rows (auto-materialised by COPY's FK -// guard with everything blank but the ID).

Capability probe (fts_probe_test.go) confirms the call surface: - INSTALL FTS + LOAD EXTENSION FTS once per database - CALL CREATE_FTS_INDEX('table', 'name', [columns]) - CALL QUERY_FTS_INDEX('table', 'name', 'query') (3-arg, no limit) - Auto-updates on later table writes — no drop / rebuild needed The one rough edge surfaced by the probe: Ladybug's default tokeniser does NOT split camelCase or snake_case. `ValidateToken` indexes as a single token `validatetoken`, so a query `validate` returns 0 hits — that's a recall regression vs our in-process BM25 backend which has explicit camelCase / snake_case / path-segment splitting (internal/search.Tokenize). This commit bridges the gap by pre-tokenising at write time and applying the same tokeniser on the read side: - SymbolFTS sidecar table holds (id, tokens) — the tokens column is the camelCase-/snake-/path-split form of the symbol's name + qual_name, joined by spaces. Stored separately from the main Node table so the bulk-load path doesn't have to learn the FTS schema. - UpsertSymbolFTS(nodeID, tokens) writes to the sidecar with MERGE so a re-parse of a file replaces the prior text in place (no duplicates). - BuildSymbolIndex installs + loads the extension and calls CREATE_FTS_INDEX over SymbolFTS.tokens. Idempotent via an atomic sentinel; lazy-builds on the first SearchSymbols if the indexer hasn't called it yet. - SearchSymbols runs the user query through search.Tokenize (same splitter as the write side), joins with spaces, and fires CALL QUERY_FTS_INDEX. Returns sorted hits with their BM25 scores. Falls back to search.TokenizeQuery when Tokenize drops every term (short queries like "go" / "js" that the strict tokeniser would silently swallow). Wires through the new graph.SymbolSearcher capability interface (UpsertSymbolFTS / BuildSymbolIndex / SearchSymbols). The SymbolHit shape mirrors what the daemon's search_symbols path needs. Other backends (sqlite / duckdb) don't implement it yet; the indexer-side integration that consumes it (skip Bleve when SymbolSearcher is present) is the next commit. Conformance test matrix (TestSymbolSearcher_EndToEnd, 6 sub-cases): - exact identifier ("ValidateToken") ✓ top hit - camelCase head ("validate") ✓ 2 hits - camelCase tail ("token") ✓ top hit - two-word query ("validate token") ✓ top hit - qualifier hop ("auth" via qual_name) ✓ 2 hits - control miss target ("pretty") ✓ top hit Plus TestSymbolSearcher_AutoUpdate (post-create upserts findable without rebuild) and TestSymbolSearcher_IdempotentUpsert (text replacement, no duplicate rows). --- internal/graph/store.go | 45 ++++ internal/graph/store_ladybug/fts.go | 234 ++++++++++++++++++ .../graph/store_ladybug/fts_probe_test.go | 148 +++++++++++ internal/graph/store_ladybug/fts_test.go | 143 +++++++++++ internal/graph/store_ladybug/schema.go | 17 ++ internal/graph/store_ladybug/store.go | 5 + 6 files changed, 592 insertions(+) create mode 100644 internal/graph/store_ladybug/fts.go create mode 100644 internal/graph/store_ladybug/fts_probe_test.go create mode 100644 internal/graph/store_ladybug/fts_test.go diff --git a/internal/graph/store.go b/internal/graph/store.go index 2b81cb2..52bc382 100644 --- a/internal/graph/store.go +++ b/internal/graph/store.go @@ -295,3 +295,48 @@ type BulkLoader interface { BeginBulkLoad() FlushBulk() error } + +// SymbolHit is a single full-text-search result: the matched node ID +// plus its relevance score from the backend's scorer (BM25 in +// Ladybug's FTS).

Wire the indexer to populate the backend FTS from the same node stream that drives the disk-store bulk load, plus mirror per-call updates so incremental reindex doesn't diverge. Three pieces: 1. graph.SymbolSearcher gains BulkUpsertSymbolFTS(items) — the cold-load fast path. Per-call UpsertSymbolFTS is fine for incremental updates (1 file change → tens of nodes) but pays ~1ms/MERGE × 600k nodes = 10 minutes on a Vscode cold-start. Bulk path implemented on store_ladybug via TSV + COPY FROM, mirroring the existing Node / Edge bulk loader: dedup by ID, wipe-and-rewrite (no append), invalidate the indexBuilt sentinel so the next SearchSymbols rebuilds the FTS. 2. internal/indexer.go drain wires SymbolSearcher into the shadow-swap path: as DrainNodes yields each node, if the disk target is a SymbolSearcher and the node passes shouldIndexForSearch (same filter the in-process BM25 backend uses — keeps the FTS corpus and BM25 corpus identical), append a SymbolFTSItem with the tokens computed by ftsTokensFor. After FlushBulk, call BulkUpsertSymbolFTS + BuildSymbolIndex. Reporter emits a `building symbol fts` stage so the UI can show progress. 3. internal/indexer.go incremental-reindex path adds a parallel UpsertSymbolFTS call alongside the existing idx.search.Add, gated on idx.graph.(graph.SymbolSearcher). The two indexes stay in sync without the daemon having to dual-write explicitly. ftsTokensFor folds n.QualName into the tokenised text so a query like "auth" still matches "auth.ValidateToken" (qualifier-hop recall the in-process BM25 backend has by handling QualName as a separate field). Tokens go through search.Tokenize so camelCase / snake_case / path-segment splitting matches the BM25 contract. Bench wiring + Bleve skip ride in the next commit; with this commit alone the backend FTS is populated but search_symbols still reads from Bleve. Test sweep stays clean (one pre-existing perf flake in TestAnalyzeImpact_FastPathSubMillisecond unrelated to this change). --- internal/graph/store.go | 27 +++++-- internal/graph/store_ladybug/fts.go | 116 ++++++++++++++++++++++++++++ internal/indexer/indexer.go | 80 +++++++++++++++++++ 3 files changed, 218 insertions(+), 5 deletions(-) diff --git a/internal/graph/store.go b/internal/graph/store.go index 52bc382..e4109a4 100644 --- a/internal/graph/store.go +++ b/internal/graph/store.go @@ -304,6 +304,15 @@ type SymbolHit struct { Score float64 } +// SymbolFTSItem is the payload BulkUpsertSymbolFTS takes per node: +// the node's ID and its pre-tokenised text.

Plug the read side: a search.Backend adapter that forwards Search to graph.SymbolSearcher.SearchSymbols, picked up at indexer construction when the store implements the capability. internal/search/symbolsearcher_backend.go: search.SymbolSearcherBackend implements search.Backend over a graph.SymbolSearcher. Search forwards to SearchSymbols and translates per-hit (NodeID, Score) into search.SearchResult. Add / Remove are no-ops because the indexer drives the SymbolSearcher writes directly (BulkUpsertSymbolFTS at drain, per-call UpsertSymbolFTS in the incremental path) — never through the search.Backend contract. Count tracks deltas-since- construction as best-effort observability. internal/indexer/indexer.go: initialSearchBackend(g) picks the search backend the Swappable wraps on construction. If g implements graph.SymbolSearcher, the adapter is the initial backend; otherwise the existing search.NewAuto path (BM25 with Bleve auto-upgrade) is used. Net effect today: any indexer.New on a Ladybug-backed store routes every Engine.SearchSymbolsScoped / SearchSymbolsRanked call through CALL QUERY_FTS_INDEX in Ladybug's vectorised engine instead of the in-process BM25 / Bleve index. What's still not bypassed yet — and what the next commit covers: the Swappable's auto-upgrade goroutine still runs, builds Bleve from AllNodes once the corpus crosses search.AutoThreshold, and swaps it in. That defeats this commit's purpose at large repo size by reinstating the ~100MB Bleve heap.

That was the right behaviour when the only options were BM25 (small corpus) and Bleve (large corpus) — but with the SymbolSearcher adapter now serving Search via the disk store's native FTS, an auto-upgrade would: 1. Spawn a 30-60s background build of a parallel in-process Bleve index covering the SAME corpus the disk FTS already holds — wasted CPU. 2. Allocate ~100MB of heap for Bleve's tokeniser + posting lists — the exact memory the FTS path was meant to release. 3. Silently Swap() the SymbolSearcherBackend out for Bleve once the build completes — defeating the FTS path entirely. Every search_symbols call after the swap would hit Bleve instead of the disk FTS, and the user would never know. Gate the upgrade on isSymbolSearcherBackend(idx.search): when the active backend is the FTS adapter, don't spawn. The upgradeOnce.Do still records the gate so a later reindex on the same indexer instance also stays on the adapter — symmetric with the existing "one upgrade per indexer lifetime" contract. isSymbolSearcherBackend unwraps the Swappable to inspect the underlying backend, since search.Backend.Inner is only on the Swappable type. Defensive nil-handling so callers in tests that pass a non-Swappable can still call it. This commit completes the FTS read-path migration: every search on a Ladybug-backed daemon now goes to native FTS, no Bleve build runs at any point of the indexer lifecycle.

Cold-load shape: - Accumulate (id, vec) pairs alongside the existing vecBackend.Add loop. No extra pass; the slice is built from the same vector slice the in-process backend consumes. - One BulkUpsertEmbeddings + one BuildVectorIndex call after the loop. Both errors logged at warn, non-fatal — the in-process backend still works as the fallback path until Vector Step 3 routes reads through. - Skipped when the store doesn't implement VectorSearcher (sqlite, duckdb, in-memory) so the existing path keeps working byte-for-byte for those backends. The in-process HNSW build stays for now. The next commit (Vector Step 3) extends search.SymbolSearcherBackend to also implement search.ChannelSearcher's vector channel, gating the in-process NewVector / Add loop behind the same hasVectorSearcher check that this commit consults. That's where the ~1GB heap saving on Vscode-scale shows up. This commit on its own is observably a no-op for the daemon — both the in-process and backend HNSW are populated and the read path still hits the in-process one. The behaviour shift comes with Step 3. --- internal/indexer/indexer.go | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) diff --git a/internal/indexer/indexer.go b/internal/indexer/indexer.go index dc2cf07..c46db91 100644 --- a/internal/indexer/indexer.go +++ b/internal/indexer/indexer.go @@ -3082,9 +3082,35 @@ func (idx *Indexer) buildSearchIndex() { } vecBackend := search.NewVector(dims) + // Backend FTS — VectorSearcher capability bridging: if the + // underlying store implements graph.VectorSearcher, mirror + // every embedding into its native HNSW too.

Two pieces: - internal/search/vector.go: VectorBackend gains a delegate field + SetDelegate(VectorDelegate). When set, Add becomes a no-op (bumps a delegateCount so HybridBackend's `Count() > 0` gate still fires once the indexer has populated the corpus), Search forwards to delegate.SimilarTo, Count returns the delta count. The in-process hnsw.Graph is never touched — nothing is allocated for the parallel index. SetDelegate is safe to call once at construction; HybridBackend's SetChunkMap and other state stays live so de-chunking and dim reporting keep working. Search.VectorDelegate is exported with a graph.VectorHit return so the indexer can install a delegate without writing a per-package translation type — search already imports graph for SymbolHit, so the type sharing is free. - internal/indexer/indexer.go: buildSearchIndex's vector branch now detects graph.VectorSearcher on idx.graph and installs a vectorSearcherDelegate before the vec.Add loop. The same loop still drives BulkUpsertEmbeddings on the backend (Vector Step 2) — the only behavioural change here is that the in-process hnsw.Graph never holds the vectors, freeing roughly dim × 4 × N bytes of heap (≈ 1 GB at 384-dim × 663k symbols on a Vscode-scale repo). Read path on a Ladybug-backed daemon: HybridBackend.SearchChannels → embedder.Embed(query) → VectorBackend.Search → delegate .SimilarTo → CALL QUERY_VECTOR_INDEX in Ladybug's vectorised engine. Same shape the FTS path took. Bench (Vector Step 4) measures the heap delta on a corpus with embeddings actually populated.

Liberal t.Logf logging so the probe surfaces what works regardless of where the binder lands. Findings (Ladybug 0.16 via go-ladybug v0.13.1): - INSTALL ALGO + LOAD EXTENSION ALGO: both succeed; same dance as FTS + VECTOR (extension is shipped in the dylib but needs the explicit catalog-load step before CALL functions appear). - CALL PROJECT_GRAPH('G', ['Node'], ['Edge']) is the prerequisite for every algo. Projections are named, persistent within the connection, and addressable by name; CALL DROP_PROJECTED_GRAPH cleans them up. Named-arg syntax (page_rank(..., dampingFactor := 0.85, maxIterations := 20)) parses fine. - page_rank — hub gets 0.115 vs next-highest 0.048 (3.5×), correctly identifying the highest in-degree node. - louvain — 2 communities matching the triangle structure (x.go + hub = group 0, y.go = group 1). - weakly_connected_components — 1 WCC of 7 nodes (the bridge c -> d unifies the otherwise-disjoint triangles). - strongly_connected_components + strongly_connected_components_kosaraju — 3 SCCs: {a,b,c}, {d,e,f}, {hub}. BFS and DFS variants agree. - k_core_decomposition — every node at k=3 (algo treats edges as undirected; all 7 have undirected degree ≥3). Every algo returns rows in the shape `(node, )` where node is a node object — we project `node.id AS id` to map back to the gortex node ID. No extra projection metadata is needed; the algo operates directly on the projected Node table. Designed-but-unconfirmed: projection predicates via the filtered form `{'Node': 'n.kind = "function"'}` — the docs claim it, the probe doesn't exercise it.

When the backing graph.Store implements graph.PageRanker (today only store_ladybug), `analyze kind=pagerank` delegates to Ladybug's parallel Ligra-based implementation; otherwise it falls back to the existing in-process analysis.ComputePageRank. Four pieces: - internal/graph/store.go: PageRanker interface + PageRankOpts / PageRankHit types. Mirrors SymbolSearcher / VectorSearcher in shape: optional capability, callers gate on the type assert, backends opt in. Opts carry NodeKinds / EdgeKinds (rewritten into a projected-graph predicate), DampingFactor, MaxIterations, Tolerance, Limit. Zero values defer to the backend's tuned defaults. - internal/graph/store_ladybug/algo.go: shared ALGO-extension scaffolding (algoState + ensureAlgoExtensionLocked + projectGraphLocked + dropProjectionLocked + withProjection) plus the PageRank method itself. The project → run → drop lifecycle is wrapped in algo.projectionMu so concurrent algo calls don't race on the projection name. NodeKinds filter becomes a predicate map `{'Node': 'n.kind = "function" OR ...'}` — Ladybug rejects multi-table predicates so node and edge filters emit independently. - internal/graph/store_ladybug/algo_test.go: five conformance tests covering the happy path (hub ranks #1 by 3.5x margin), Limit, NodeKinds filter, tuning knobs (named-arg path), consecutive-call hygiene (project → drop → project leak check). - internal/mcp/tools_analyze_pagerank.go: new `analyze kind=pagerank` dispatch routed through s.backendStore(). On engine-native error, falls through to ComputePageRank rather than surfacing a half-finished result. NodeKinds filter honoured on both paths (engine-native via PROJECT_GRAPH predicate, fallback via post- filter on the result map). Sample on the probe graph (hub-and-spoke + two SCC triangles): hub rank=0.115 (3.5x next-highest — high in-degree) d / e / f rank=~0.045 (y.go triangle nodes) c / b / a rank=~0.035 (x.go triangle nodes) The handler doesn't yet route the cached Server.pageRank through the capability — that's a search-rerank wiring change with a different blast radius. Done as part of Step 5 alongside the other three algos. --- internal/graph/store.go | 55 ++++++ internal/graph/store_ladybug/algo.go | 210 ++++++++++++++++++++++ internal/graph/store_ladybug/algo_test.go | 139 ++++++++++++++ internal/graph/store_ladybug/store.go | 6 + internal/mcp/tools_analyze_pagerank.go | 190 ++++++++++++++++++++ internal/mcp/tools_enhancements.go | 6 +- 6 files changed, 604 insertions(+), 2 deletions(-) create mode 100644 internal/graph/store_ladybug/algo.go create mode 100644 internal/graph/store_ladybug/algo_test.go create mode 100644 internal/mcp/tools_analyze_pagerank.go diff --git a/internal/graph/store.go b/internal/graph/store.go index 42443d1..8ebf47f 100644 --- a/internal/graph/store.go +++ b/internal/graph/store.go @@ -429,3 +429,58 @@ type VectorSearcher interface { BuildVectorIndex(dims int) error SimilarTo(vec []float32, limit int) ([]VectorHit, error) } + +// PageRankOpts tunes the PageRank computation.

Same shape as the PageRanker capability: when the backing graph.Store implements graph.CommunityDetector (today only store_ladybug), `analyze kind=louvain` delegates the partitioning step to Ladybug's parallel Grappolo implementation; otherwise falls back to the existing pure-Go DetectCommunitiesLouvain. Four pieces: - internal/graph/store.go: CommunityDetector interface + CommunityOpts (NodeKinds, EdgeKinds, MaxPhases, MaxIterations) + CommunityHit (NodeID + opaque CommunityID int64). Sits next to PageRanker. - internal/graph/store_ladybug/algo.go: Louvain method on the Store. Reuses the same withProjection helper from PageRank (project → run → drop under algo.projectionMu) so projection- name collisions across interleaved algo calls are impossible. asInt64 helper normalises the int-shaped scalars the binding surfaces (int64 / int / float64 depending on call site). - internal/analysis/communities.go: extracted the post- processing tail of DetectCommunitiesLouvain into finaliseCommunityPartition(nodes, comm, …) so both the in-process and engine-native paths share the same label disambiguation / cohesion / hub / parent assignment / modularity computation. New DetectCommunitiesLouvainBackend wraps CommunityDetector.Louvain → finaliseCommunityPartition, so the engine-native path produces a shape-identical CommunityResult — downstream consumers can't tell the difference. - internal/mcp/tools_analyze_pagerank.go: new `analyze kind=louvain` handler that routes through s.backendStore()'s CommunityDetector when available, otherwise calls the in-process DetectCommunitiesLouvain. Distinct from `analyze kind=clusters` which uses Leiden (the Server's cached communities) — Louvain exposes a different (typically more granular) partition that some clients want first-class access to. Engine-native error falls through to in-process rather than surfacing a half-done result. Conformance: 4 ladybug tests cover the happy path (two triangles → two communities, members of the same triangle land together), tuning knobs, consecutive-call hygiene, and interleaved PageRank-then-Louvain (catches a regression where the shared projection name would collide between algos).

Same routing shape as PageRanker / CommunityDetector: backend-implemented when the store offers it, in-process fallback otherwise. Five pieces: - internal/graph/store.go: ComponentFinder interface with both methods on one type (the two algos always travel together) + ComponentOpts (NodeKinds, EdgeKinds, MaxIterations) + ComponentHit (NodeID + opaque ComponentID int64). - internal/graph/store_ladybug/algo.go: WeaklyConnectedComponents and StronglyConnectedComponents share a runComponentAlgo helper (both algos return the same (node, group_id) shape). Picks Ladybug's BFS-based SCC by default; strongly_connected_components_kosaraju is available via graph_query when callers want the DFS variant. - internal/analysis/components.go: pure-Go ComputeWCC + ComputeSCC fallbacks. WCC is BFS-from-each-unseen-node. SCC is iterative Tarjan — the explicit (node, neighbour-iteration-index) stack replaces recursion so a deep call graph won't blow the goroutine stack. collectComponents dedupes the "sort by size, renumber, apply MinSize" boilerplate both algos need. - internal/analysis/components_test.go: 5 tests covering the happy path, edge-kind filter, MinSize singleton elision, and a 10k-node straight-line graph that verifies the iterative Tarjan handles depth without stack overflow. - internal/mcp/tools_analyze_components.go: shared handleAnalyzeConnectedComponents(ctx, req, directed) handler serves both `analyze kind=wcc` and `analyze kind=scc`. Args: limit (number of components), min_size (drop trivial SCCs), member_limit (cap members per row for token economy). Conformance ladybug-side: 3 tests cover WCC (one component for the hub-bridged graph), SCC (3 components: {a,b,c}, {d,e,f}, {hub}), and the MaxIterations tuning knob.

Find the densely connected centre of the graph. Five pieces: - internal/graph/store.go: KCorer interface + KCoreOpts (NodeKinds, EdgeKinds — no per-call tuning, the algo always runs the full decomposition) + KCoreHit (NodeID + KDegree int64). - internal/graph/store_ladybug/algo.go: KCoreDecomposition runs CALL k_core_decomposition over the standard PROJECT_GRAPH('Node', 'Edge') projection. No per-call knobs. - internal/analysis/kcore.go: pure-Go ComputeKCore — the classic Batagelj & Zaversnik 2003 bucket algorithm (O(V + E), no recursion). Builds the dense node index, undirected dedupe-on-edge adjacency, processes nodes in degree-ascending order via bucket lists with O(1) move-down. - internal/analysis/kcore_test.go: 4 tests covering a 4-clique + leaf (clique members at k=3, leaf at k=1), a 4-node line (everyone at k=1), an empty graph (no hits), and an edge- kind filter that isolates a node. - internal/mcp/tools_analyze_kcore.go: `analyze kind=kcore` handler routed through s.backendStore(). Args: limit (cap rows), min_degree (drop trivial low-core nodes), kind (NodeKinds filter). Engine-native errors fall through to the in-process path. Conformance ladybug-side: 2 tests cover the happy path (every node in the hub-and-spoke + two-triangle graph has k=3 because all nodes have ≥3 undirected neighbours — the whole graph is its own 3-core) and consecutive-call projection-leak hygiene. K-core pairs well with PageRank: PageRank weights influence by random-walk authority, k-core weights structural density. Both exposed as first-class analyze kinds.

charset=UTF-8 Content-Transfer-Encoding: 8bit store-bench now reports a single-sample wall-clock for each of the four graph algorithms wired through capability interfaces. Routing per backend: - implements the capability interface (today only ladybug) → times the engine-native CALL. - is the in-memory *graph.Graph (memory backend) → times the in-process analysis.* fallback. - anything else (sqlite, duckdb) → skipped. Their in-process equivalents would require copying state into *graph.Graph, and the one-time copy would dominate the measurement, making the comparison meaningless. Sample (gortex repo, ~190k nodes, ~607k edges): | algo | in-process (memory) | engine-native (ladybug) | winner | |------------|---------------------|-------------------------|-------------------| | pagerank | 2552ms | 4091ms | in-process (1.6x) | | louvain | 1954ms | 630ms | ladybug (3.1x) | | wcc | 169ms | 995ms | in-process (5.9x) | | scc | 188ms | 1554ms | in-process (8.3x) | | kcore | 294ms | 1282ms | in-process (4.4x) | Interpretation: the engine-native algos win where parallelism pays off relative to the projection overhead (Louvain — parallel Grappolo is genuinely fast on dense graphs) and lose where the algorithm itself is cheap (WCC / SCC / K-Core — projection + Cypher round-trip dominates the actual work). PageRank's comparison is muddied because the in-process implementation restricts to call+reference edges while the engine-native runs on the full edge set with tolerance-based convergence — they're not literally the same workload. The picture is qualitatively different from FTS / Vector (engine-native won by 10-50x): there, the wins came from specialised data structures (inverted index, HNSW); for graph algos the actual computation is small per-edge and the overhead of marshalling through Cypher is comparable to the work itself. The routing decision is per-algo, not all-or-nothing. singleSample turns a one-shot measurement into the toolStats triple the per-tool table expects (both p50 and p95 land on the same number; N=1). Acceptable for an order-of-magnitude comparison; a more careful bench would multi-run with cooldown. --- bench/store-bench/main.go | 93 ++++++++++++++++++++++++++++++++++++++- 1 file changed, 92 insertions(+), 1 deletion(-) diff --git a/bench/store-bench/main.go b/bench/store-bench/main.go index 196837c..9027d3c 100644 --- a/bench/store-bench/main.go +++ b/bench/store-bench/main.go @@ -34,6 +34,7 @@ import ( "go.uber.org/zap" + "github.com/zzet/gortex/internal/analysis" "github.com/zzet/gortex/internal/config" "github.com/zzet/gortex/internal/graph" "github.com/zzet/gortex/internal/graph/store_duckdb" @@ -378,6 +379,17 @@ func runBackend( } } + // Graph-algorithm timings: pagerank / louvain / wcc / scc / kcore. + // Each cell is a single wall-clock measurement of the algorithm + // running over the populated store.

For each backend (memory, sqlite, duckdb, ladybug): - Builds a fresh graph.Store via factory - Fresh ConfigManager pointing at ~/.config/gortex/config.yaml - indexer.NewMultiIndexer over the store (same wiring as the daemon, minus the embedder) - mi.IndexAll() — runs per-repo Indexer goroutines + deferred cross-cutting passes + global graph passes - Cross-repo edges probe: counts edges whose endpoints have different RepoPrefix — the load-bearing capability multi-repo indexing exists to deliver - GetNode sample (p50 / p95), heap snapshot, disk size Scope selection via flags: -all-repos bench every repo in the global config (blanks ActiveProject so ActiveRepos returns all) -projects=a,b union the named projects default honour active_project (the daemon's behaviour) Caveat: a live run today shows ladybug stuck deep in per-row lbug_connection_execute calls — MultiIndexer's per-repo Indexers each drain their own shadow independently, so the bulk-load COPY path is not amortised across repos the way it is on a single-repo cold index. That's MultiIndexer perf work, not bench work; the harness is wired so a fixed MultiIndexer drops in without re-plumbing the bench. Committed at this point so the harness survives the upcoming mcp.Server.graph -> graph.Store refactor that's about to land. --- bench/multi-repo-bench/main.go | 574 +++++++++++++++++++++++++++++++++ 1 file changed, 574 insertions(+) create mode 100644 bench/multi-repo-bench/main.go diff --git a/bench/multi-repo-bench/main.go b/bench/multi-repo-bench/main.go new file mode 100644 index 0000000..930267c --- /dev/null +++ b/bench/multi-repo-bench/main.go @@ -0,0 +1,574 @@ +// Command multi-repo-bench measures multi-repository indexing +// across graph.Store backends. +// +// The single-repo store-bench tells us the per-backend cost of +// indexing one repo through the full pipeline.

Every public function that previously took *graph.Graph as a parameter now takes graph.Store (the interface *graph.Graph already implements). What changed: - internal/mcp/Server.graph: *graph.Graph -> graph.Store - 55 files across 18 packages: parameter signatures only - 3 struct fields where the parameter-type change cascaded (wiki.Inputs.Graph, wiki.Generator.graph, docs.Deps.Graph, dataflow.Engine.g, skills.Generator.graph) - 2 in-package functions in internal/graph: ClassifyZeroEdge, CaveatForZeroEdge No behavioural change: every method called on a parameter is on the graph.Store interface, *graph.Graph satisfies graph.Store, and every existing caller continues to work because Store is strictly more permissive than *graph.Graph. What this unlocks: the daemon can now construct a Server with any graph.Store implementation (store_ladybug, store_sqlite, store_duckdb), not just the in-memory *graph.Graph. The capability interfaces (PageRanker, CommunityDetector, ComponentFinder, KCorer, SymbolSearcher, VectorSearcher) auto-engage via the existing type assertions in handleAnalyze*.

The Go binding shares one kuzu_connection handle across goroutines; concurrent conn.Query calls (e.g. per-repo Indexers all running NodeCount on shadow-swap entry) raced in the C layer and SIGSEGV'd. Fixed by routing every querySelect through a writeMu lock; querySelectLocked sidesteps the lock via a shared querySelectInner so caller-locked paths still work. 2. **Snapshot cache replay on persistent backends** — server.go loaded from gob+gzip snapshot via per-row g.AddNode for any --backend, including ladybug. That replays 190k+ AddNode calls per-row through ladybug's MERGE Cypher path (glacial). The snapshot is for in-memory state recovery; on-disk backends already persist across restarts and don't need it. Fixed by switching to persistence.NopStore when backend isn't memory. 3. **MultiIndexer hijacking --index** — useMulti was simply `mi != nil`. With a populated default config and an explicit `--index ` flag, the daemon ignored --index and ran multi-repo. Tightened the gate to `mi != nil && hasActiveRepos && serverIndex == ""` so `--index` is honoured. 4. **MCP `analyze kind=pagerank|kcore` returning 0 rows** — my own bug. The analyze dispatcher reads `kind` to pick the handler; then handlePageRank / handleKCore also read `kind` (intending it as a NodeKinds filter) and got the dispatcher's "pagerank" string, parsed it as a NodeKind, matched nothing. Renamed the per-handler arg to `node_kinds`. 5. **Silent daemon during long indexing** — non-TTY runs went silent for minutes (Spinner is /dev/tty-only). Added progress.ZapReporter (logs every stage transition + every N seconds intra-stage) and progress.StartHeartbeat (5-second goroutine emitting current node/edge counts). Cmd/gortex/server.go wires the heartbeat around the indexing goroutine. 6. **indexer.go IndexCtx instrumentation** — added the "indexer: shadow-swap decision" log line (bulk_loader, pre_nodes, pre_edges, files, below_shadow_max, shadow_taken) plus drain-start / FlushBulk start / FlushBulk complete timings on the shadow path. Critical for the multi-repo debugging — surfaced the gate-fairness bug. 7. **store_ladybug.fts.go bulk path** — already in the prior commit; .tsv → .csv extension for the COPY parser. 8. **cmd/lbug-probe** — tiny in-module program to verify store_ladybug.Open() against arbitrary paths. Surfaced that ladybug Open fails on bare /tmp/store paths (works inside subdirs); workaround noted in --backend-path docs. Single-repo end-to-end works on both backends. Multi-repo on ladybug surfaces the next bug — per-repo shadow-swap gate races and the big repo falls back to per-row writes — covered in the next commit. --- cmd/gortex/server.go | 55 ++++++++++-- cmd/lbug-probe/main.go | 23 +++++ internal/graph/store_ladybug/store.go | 28 ++++-- internal/indexer/indexer.go | 38 ++++++++- internal/mcp/tools_analyze_kcore.go | 2 +- internal/mcp/tools_analyze_pagerank.go | 2 +- internal/progress/zaplog.go | 114 +++++++++++++++++++++++++ 7 files changed, 243 insertions(+), 19 deletions(-) create mode 100644 cmd/lbug-probe/main.go create mode 100644 internal/progress/zaplog.go diff --git a/cmd/gortex/server.go b/cmd/gortex/server.go index 41de214..d212656 100644 --- a/cmd/gortex/server.go +++ b/cmd/gortex/server.go @@ -1,6 +1,7 @@ package main import ( + "context" "fmt" "net" "net/http" @@ -14,6 +15,7 @@ import ( "strings" "github.com/zzet/gortex/internal/config" + "github.com/zzet/gortex/internal/progress" "github.com/zzet/gortex/internal/contracts" "github.com/zzet/gortex/internal/daemon" "github.com/zzet/gortex/internal/indexer" @@ -328,7 +330,7 @@ func runServer(cmd *cobra.Command, _ []string) error { } // Multi-repo support. - cm, err := config.NewConfigManager("") + cm, err := config.NewConfigManager(cfgFile) if err != nil { fmt.Fprintf(os.Stderr, "[gortex] warning: could not load global config: %v\n", err) } @@ -422,11 +424,24 @@ func runServer(cmd *cobra.Command, _ []string) error { srv.SetLSPDiagnosticsBroadcasting() } - // Create persistence store. + // Create persistence store.

That implicitly assumed every repo in a workspace pinned to the same language SDK version and the same dependency versions. Two repos on different Go versions have semantically distinct stdlib symbols (Go 1.21's `min` is a builtin; in 1.20 it isn't); a global ID conflates them. New format: `::::` (e.g. `gortex::stdlib::fmt::Errorf`). Empty repoPrefix falls back to the legacy form and the helpers still recognise it. Files: - internal/graph/stub.go — new: StubID, IsStub, StubKind, IsStdlibStub / IsBuiltinStub / IsExternalCallStub / IsModuleStub, StubRest, StubRepoPrefix. One place to change the format if we revise it again. - internal/resolver/resolver.go — resolveExtern + applyBuiltinIfKnown use StubID with the caller's RepoPrefix. - internal/resolver/go_builtins_attribution.go — same shape. - internal/resolver/external_call_attribution.go — dedup key extended with repoPrefix; module ID and symbol ID both repo-prefixed. - internal/resolver/cross_pkg_guard.go — IsStdlibStub check. - internal/resolver/external_calls.go — IsStdlibStub + StubRest. - internal/semantic/goanalysis/externals.go — derives the repoPrefix from a source file in the first root package and threads it through to every stub it materialises. Provider signature unchanged. 2) **Per-Indexer shadow-swap sentinel** (was: NodeCount==0) The shadow-swap gate in indexer.IndexCtx asked "is the disk store empty?". That was correct for single-repo daemons but wrong for MultiIndexer: each per-repo Indexer is a fresh instance, but the disk store is shared, so once any sibling repo drained, every subsequent per-repo Indexer failed the gate and fell back to the per-row Cypher write path. On gortex's ~190k-node repo that was 30+ minutes of per-row writes. New gate: `idx.indexCount.Load() == 0` — each Indexer's first IndexCtx call takes the shadow path; subsequent re-indexes go direct. Combined with the per-repo stub prefixes above (eliminates COPY PRIMARY KEY conflicts on shared stubs across repos), every per-repo Indexer can take its own shadow and drain in parallel. This fix lands the design correctly; the remaining bottleneck (serialisation through ladybug's single connection — small repos waiting 100+ seconds for the big repo's drain to release writeMu) is the next commit's target (connection pool). 3) Also: store_ladybug/store.go writeMu fix from prior commit is the necessary serialisation that, while slow under multi-repo, prevents the SIGSEGV we saw under concurrent cgo calls. The right long-term fix is a pool, not "remove the lock". --- internal/graph/stub.go | 143 ++++++++++++++++++ internal/indexer/indexer.go | 26 +++- internal/resolver/cross_pkg_guard.go | 2 +- .../resolver/external_call_attribution.go | 55 +++++-- internal/resolver/external_calls.go | 7 +- internal/resolver/go_builtins_attribution.go | 18 ++- internal/resolver/resolver.go | 13 +- internal/semantic/goanalysis/externals.go | 44 +++++- 8 files changed, 274 insertions(+), 34 deletions(-) create mode 100644 internal/graph/stub.go diff --git a/internal/graph/stub.go b/internal/graph/stub.go new file mode 100644 index 0000000..1bf135a --- /dev/null +++ b/internal/graph/stub.go @@ -0,0 +1,143 @@ +package graph + +import "strings" + +// Stub-node identifier conventions. +// +// A "stub" is a placeholder Node the resolver materialises for a +// symbol the indexer can see referenced but not defined in the +// current repo's source: a stdlib call, a language builtin, an +// external module import, etc. Stubs let the graph hold edges +// to "external" targets uniformly with edges to first-party +// nodes. +// +// Format (all stubs): +// +// :::: +// +// where: +// +// repoPrefix — the owning repo's RepoPrefix (Indexer.RepoPrefix). +// Empty only when the stub is created outside a +// per-repo context (legacy single-repo daemons). +// kind — one of: stdlib, builtin, external_call, module. +// rest — kind-specific (e.g. "fmt::Errorf" for stdlib). +// +// Why per-repo?

Three load-bearing changes: 1) **Connection pool** (`internal/graph/store_ladybug/connpool.go`) ladybug's Go binding shares one kuzu_connection across goroutines; concurrent conn.Query → cgo race → SIGSEGV. The pool gives each goroutine its own private Connection drawn from a sync-channel of 8 pre-opened connections; on checkout the pool lazy-loads any registered extensions on the first use of that Connection. executeOrQuery now returns a release closure the caller defers — the borrowed Connection has to stay checked out until the iterator is consumed (open QueryResult holds the kuzu_query handle). 2) **Reads parallelise, writes serialise** (store.go) querySelect no longer locks writeMu (each call gets its own pool connection). FlushBulk's runCopyPooled still acquires writeMu — ladybug enforces "only one write transaction at a time" at the DB level; concurrent COPYs from different connections fail fast with the literal error "Cannot start a new write transaction in the system". Reads no longer queue behind writes; writes queue cleanly without per-row fallback. 3) **Always COPY in FlushBulk** (was: per-row MERGE fallback when disk non-empty). The fallback existed to dodge PRIMARY KEY conflicts on shared stubs; per-repo stub prefixes (prior commit) eliminate those conflicts, so the slow path was actively making things worse for multi-repo. Plus a CSV pre-rewrite step that prefixes residual `unresolved::*` ids with the per-batch repo prefix — the resolver's leftover "unresolved::import::path/filepath" ids collide across repos the same way the now-fixed stubs did, and extractors emit them too deeply to reach without a per-language refactor. Sample numbers (4-repo workspace, gortex/web/gcx-go/gcx-ts): | repo | nodes | edges | FlushBulk | |---------|-------:|--------:|----------:| | gcx-ts | 269 | 741 | 146 ms | | gcx-go | 675 | 3,264 | 195 ms | | web | 1,898 | 5,268 | 747 ms | | gortex | 68,775 | 312,689 | 2.16 s | | total | | | ~3.2 s | Memory baseline for the same workload: ~10 s. Ladybug is now 3× faster on multi-repo cold index AND persists across restarts. The earlier per-row path took 110-300 seconds per repo because gortex's per-row MERGE held writeMu while every other repo's FlushBulk waited. --- internal/graph/store_ladybug/connpool.go | 155 ++++++++++++++++++ internal/graph/store_ladybug/store.go | 195 +++++++++++++++++------ 2 files changed, 301 insertions(+), 49 deletions(-) create mode 100644 internal/graph/store_ladybug/connpool.go diff --git a/internal/graph/store_ladybug/connpool.go b/internal/graph/store_ladybug/connpool.go new file mode 100644 index 0000000..4b49f92 --- /dev/null +++ b/internal/graph/store_ladybug/connpool.go @@ -0,0 +1,155 @@ +package store_ladybug + +import ( + "fmt" + "sync" + + lbug "github.com/LadybugDB/go-ladybug" +) + +// connPool holds a fixed-size pool of *lbug.Connection bound to +// the same *lbug.Database.

With three such walks in DI alone, deferred_passes ballooned to 6+ minutes on Ladybug versus ~6s on in-memory. GetRepoEdges collapses the nested walk into a single backend query: one Cypher MATCH on Ladybug, one JOIN on SQLite/DuckDB. The in-memory implementation keeps the same observable behaviour by iterating each shard's byRepo bucket and appending outEdges in place — the in-memory backend was never the bottleneck, this method just gives the disk backends a hook that's cheap there too. Empty repoPrefix returns nil so disk backends don't silently fall through to a full-graph scan. The conformance test asserts: intra-repo edges, cross-repo edges (source in r1 → target in r2), and unresolved::* targets all come back when the source node lives in the requested repo, and that edges sourced from a different repo do not. --- internal/graph/graph.go | 26 +++++++++++ internal/graph/store.go | 13 ++++++ internal/graph/store_duckdb/store.go | 22 +++++++++- internal/graph/store_ladybug/store.go | 17 ++++++++ internal/graph/store_sqlite/store.go | 23 ++++++++++ internal/graph/storetest/storetest.go | 62 +++++++++++++++++++++++++++ 6 files changed, 162 insertions(+), 1 deletion(-) diff --git a/internal/graph/graph.go b/internal/graph/graph.go index 37a151e..9d27f72 100644 --- a/internal/graph/graph.go +++ b/internal/graph/graph.go @@ -1572,6 +1572,32 @@ func (g *Graph) GetRepoNodes(repoPrefix string) []*Node { return out } +// GetRepoEdges returns every edge whose source node has the given +// RepoPrefix — the in-memory reference implementation of the +// Store-interface method.

On disk backends each per-node call costs one prepared- statement / Cypher round-trip — the gortex repo's ~68k repo nodes turned into ~68k queries per pass, and DI extraction alone walks it three times. Each loop now drives a single GetRepoEdges(r) call instead. The extractContracts path additionally pre-buckets the already-fetched GetRepoNodes slice by FilePath to replace the per-file GetFileNodes call, and pre-buckets the GetRepoEdges result by e.From to replace per-file GetOutEdges. ~1900 file-level queries on the gortex repo go to zero. Single-repo (no repoPrefix) paths keep AllEdges / per-file lookups untouched — those paths already fan out over the whole graph cheaply on every backend.

COPY is INSERT-only on the node table, so the first collision raised a Copy exception, leaked buffer pool memory, and eventually OOM-panicked the daemon mid-warmup. Two changes to land contracts safely AND fast: 1. internal/indexer/indexer.go::bulkCommit drops the BeginBulkLoad/FlushBulk bracket. AddBatch's non-bulk-active path uses MERGE semantics on every backend, so duplicates are absorbed in place. 2. internal/graph/store_ladybug/store.go::AddBatch (non-bulk path) routes nodes through addNodesUnwindLocked instead of looping per-row upserts. The UNWIND-MERGE batch turns N node writes into ceil(N/chunk) Cypher calls — meaningful on Ladybug where each cgo round-trip is ~1 ms. Edges stay on per-call upsertEdgeLocked because the fork's UNWIND-MERGE crashes when an edge row references a node id that isn't yet in the table. Why: contracts must persist correctly on Ladybug; the COPY bracket cannot satisfy that on collision-prone IDs. How to apply: when adding a new pass that mass-emits nodes whose IDs may already exist, just call AddBatch — it now batches on the backend internally without needing a BulkLoader bracket. --- internal/graph/store_ladybug/store.go | 24 ++++++++--------- .../indexer/contracts_bulk_commit_test.go | 21 ++++++++------- internal/indexer/indexer.go | 27 +++++++------------ 3 files changed, 32 insertions(+), 40 deletions(-) diff --git a/internal/graph/store_ladybug/store.go b/internal/graph/store_ladybug/store.go index bbb1e1f..7edaa5e 100644 --- a/internal/graph/store_ladybug/store.go +++ b/internal/graph/store_ladybug/store.go @@ -357,20 +357,18 @@ func (s *Store) AddBatch(nodes []*graph.Node, edges []*graph.Edge) { s.writeMu.Lock() defer s.writeMu.Unlock() - // Per-call AddNode/AddEdge loop instead of the Kuzu-style UNWIND - // path.

DuckDB was a useful columnar-SQL experiment but the go-duckdb cgo footprint (six platform-tagged binding modules pulled in transitively) doesn't pay for itself once ladybug is the production target, and the schema / appender plumbing is divergent enough from sqlite to make every Store-interface change carry double the per-backend cost.

This commit walks every remaining mention and either rewires the call onto ladybug (the bench tools that compare memory vs a disk Store still want a disk Store) or generalises the prose to "disk backend" so nothing points at a package that no longer exists. - bench/node-diff and bench/edge-diff are rewritten onto store_ladybug under the \`ladybug\` build tag, with non-tagged stub mains so the packages still compile when the binary is built without ladybug. - bench/store-bench and bench/multi-repo-bench drop their sqlite and duckdb branches, flag values, and "only" set entries; ladybug stays as the single disk-backed comparison point. - Comments in internal/graph/store.go, internal/indexer/{indexer, shadow_threshold}.go, internal/resolver/* and cmd/gortex/{server, daemon_state}.go that named sqlite or duckdb are rewritten in backend-neutral language ("disk backend"). --- bench/edge-diff/main.go | 24 ++--- bench/edge-diff/stub.go | 17 ++++ bench/multi-repo-bench/main.go | 46 +--------- bench/node-diff/main.go | 26 +++--- bench/node-diff/stub.go | 17 ++++ bench/store-bench/main.go | 91 ++++--------------- cmd/gortex/daemon_state.go | 4 +- cmd/gortex/server.go | 12 +-- internal/graph/store.go | 11 +-- internal/indexer/indexer.go | 11 +-- internal/indexer/shadow_threshold.go | 3 +- .../resolver/external_call_attribution.go | 6 +- internal/resolver/module_attribution.go | 4 +- internal/resolver/relative_imports.go | 4 +- internal/resolver/resolver.go | 19 ++-- 15 files changed, 113 insertions(+), 182 deletions(-) create mode 100644 bench/edge-diff/stub.go create mode 100644 bench/node-diff/stub.go diff --git a/bench/edge-diff/main.go b/bench/edge-diff/main.go index 0a667f2..19174a0 100644 --- a/bench/edge-diff/main.go +++ b/bench/edge-diff/main.go @@ -1,4 +1,6 @@ -// Command edge-diff indexes the same repo twice (memory + sqlite) and +//go:build ladybug + +// Command edge-diff indexes the same repo twice (memory + ladybug) and // prints the symmetric difference of the edge sets, classified by // (Kind, FromKind, ToKind).

Source had no remaining importers, so this is purely mechanical cleanup; running go mod tidy reproduces the same go.mod state. --- go.mod | 24 +---------------- go.sum | 82

charset=UTF-8 Content-Transfer-Encoding: 8bit Why: FindUsagesScoped issued one Reader.GetNode per inbound edge to the target symbol — on Ladybug each is a cgo Cypher call (~14ms), so a hot symbol with hundreds of callers turned a single find_usages into seconds of round-trip overhead. analyze kind=kcore had the same per-id GetNode pattern as analyze(pagerank) for hit→row hydration. FindUsagesScoped now pre-filters inbound edges by kind (via the hoisted isUsageEdgeKind helper) and batches the From-node lookup into one GetNodesByIDs call.

On gortex-scale graphs (313k+ edges) one rebuild costs 30+s, so a repeat PageRank call after a single graph mutation was paying ~30s of pure rebuild cost on the projection alone. Caching it across calls drops the second-and-later analyze(pagerank) from ~63s to ~1.3s when the underlying graph hasn't changed. Implementation: - algoState gains a projectionCacheEntry keyed by canonicalised projectionOpts (nodeKinds + edgeKinds, sorted for order-independence). - Store.writeGen (atomic.Uint64) advances on every mutation that hits disk: AddNode, AddEdge, AddBatch, SetEdgeProvenance(Batch), ReindexEdge(s), RemoveEdge, EvictFile/Repo, FlushBulk, and every backend resolver pass that actually rewrites edges. Reads do not bump it. - withProjection's fast path returns the cached projection name when the cache key and writeGen both match. Cache miss drops the previous projection (if any) and rebuilds. Lazy invalidation — no proactive drop on writes. - dropCachedProjection runs from Store.Close so the engine's catalog isn't left holding a dangling projection across teardown. The projection lifecycle (INSTALL ALGO + LOAD + PROJECT_GRAPH + algo CALL + DROP) is now pinned to the setup conn (s.conn) via two new helpers, runCypherOnSetupSafe / querySelectOnSetupSafe. Ladybug binds projected-graph declarations to the connection that ran them, and the pool was previously cycling across pool connections — surfacing as "Projected graph G does not exists" the moment the algo CALL landed on a different pool slot. Pinning fixes the pre-existing TestPageRanker_* / TestCommunityDetector_* / TestComponentFinder_* / TestKCorer_* flakes. Tests: - TestAlgo_ProjectionCachedAcrossCalls asserts the projection's generation field is unchanged across two same-opts PageRank calls AND across a Louvain call with the same shape. - TestAlgo_ProjectionRebuiltAfterWrite asserts a post-PageRank AddNode bumps writeGen and the next PageRank rebuilds. - TestAlgo_ProjectionRebuiltOnShapeChange asserts a NodeKinds-filtered PageRank after an unfiltered one replaces the cache entry's key.

Mirrors the existing GetNodesByIDs / IN $ids pattern, with the same dedupeNonEmpty + stringSliceToAny plumbing. - *OverlaidView routes overlay-owned ids to the per-session layer, fans the remainder out to base in one batched call, then re-applies the same per-id overlay-deleted-target / overlaid-source filters GetIn/OutEdges already apply. - storetest gains testGetEdgesByNodeIDs: small fan-in/fan-out graph, mixed present/missing/duplicate/empty-string ids; asserts the per-id slices match what GetIn/OutEdges would return individually + the nil-slice-for-missing semantics callers depend on.

At ~14ms per cgo round-trip that's ~2.5s of pure cgo plumbing per search. smart_context fires 5+ such searches and was ~800x slower than the in-memory baseline. Batching collapses the ~180 round-trips into ~4 (two for prepare, plus one out-edge batch in the graph_completion retriever — signals reuse the cache). Implementation: - rerank.Context grows outEdgeCache / inEdgeCache (map[id][]*Edge) populated once per Rerank by prepare(). prepare() collects every candidate's ID into one ids slice, then fires the two new GetIn/OutEdgesByNodeIDs calls instead of looping per-candidate. - Context exposes inEdges(id) / outEdges(id) accessors. Signals that previously called ctx.Graph.GetIn/OutEdges directly now go through them, so they read the prepared cache when available and fall back to a per-id Graph call when the node was outside the candidate set. FanInSignal / FanOutSignal / MinHashSignal switched. - GraphCompletion.Retrieve collects every seed ID, fires one GetOutEdgesByNodeIDs across the whole batch, walks the cached edges to collect distinct target IDs, then one GetNodesByIDs to materialise the expansion nodes. Replaces the per-seed nested GetOutEdges + per-edge GetNode loop (1 + N round-trips per seed) with two batched calls total. - retriever_test.go: fix the Seeder closure signature drift left over from the earlier graph.Store refactor (test file was a pre-existing build failure unrelated to this work; restoring it is a prereq for running the rerank suite). Per-search edge-fetch round-trip count: 6N (~180 with N=30) → 4.

One log call per query so production at info level pays nothing; bench harness greps for "search_symbols phases" at --log-level debug. Surfaces honest per-phase numbers so the disk-backend regression on ladybug stops being speculated about. Wires through: - query.SearchTimings on QueryOptions for engine-internal phases - rerank.Context.Prepare exported (+ prepared-slice flag so Pipeline.Rerank skips the duplicate prepare pass when the caller pre-invoked it for timing) - applyRerankBoostsTimed returns prepare/signals as separate durations - fetchAndMergeBM25Timed measures around each engine call so the BM25 backend wall-clock is honest Why: the rerank+materialisation N+1 is dead but the remaining search_symbols cost on ladybug was being guessed at. Per-phase numbers are needed to drive the next two perf changes — combine expansion terms into one BM25 query, and replace the AllNodes substring fallback with a backend-side filter. --- internal/mcp/combo_apply.go | 44 +++++++++++++++------ internal/mcp/tools_core.go | 60 +++++++++++++++++++++++++++-- internal/mcp/tools_search_assist.go | 18 +++++++++ internal/query/engine.go | 27 +++++++++++-- internal/query/subgraph.go | 21 ++++++++++ internal/search/rerank/context.go | 17 ++++++++ internal/search/rerank/pipeline.go | 19 ++++++++- 7 files changed, 187 insertions(+), 19 deletions(-) diff --git a/internal/mcp/combo_apply.go b/internal/mcp/combo_apply.go index c90cdf3..3dccc3e 100644 --- a/internal/mcp/combo_apply.go +++ b/internal/mcp/combo_apply.go @@ -1,16 +1,18 @@ package mcp import ( + "time" + "github.com/zzet/gortex/internal/graph" "github.com/zzet/gortex/internal/search/rerank" ) -// applyRerankBoosts is the I13 entry point that runs the full -// 11-signal rerank.Pipeline over the candidate set with the -// session-aware Context wired in (locality, combo, frecency, -// feedback, churn, community).

Both BM25 backends — the in-process BM25Backend and Ladybug's QUERY_FTS_INDEX — treat a multi-token query as an OR-style union with a single global score, so this collapses the prior N+1 round-trip pattern into exactly two BM25 calls regardless of how many synonyms the LLM expanded into. Add a per-fragment FindNodesByNames rescue after the combined call. One name-batch lookup preserves the per-term behaviour where a fragment like "BillingInvoice" finds its exact-name node even when BM25 tokenisation drops the PascalCase concatenation — without it, soup-split mode silently dropped exact matches the per-term loop used to surface via the engine's FindNodesByName fallback. Two new tests guard the invariants: - CombinedQueryUnionIsSuperset: merged result is ≥ the per-term fan-out union (no candidate dropped by collapsing into one call). - ExactNameRescuePreserved: PascalCase fragments still surface via the rescue step. Why: BM25 per-term fan-out is N round-trips on disk backends; the search hot path's expansion-merge was the second-largest cost after the now-batched edge fetch.

Replaces the search-substring fallback's prior pattern in query.Engine.gatherBackendCandidates of AllNodes()-then-Go-filter, which materialised every node (68k rows on gortex's own graph, orders of magnitude more on Linux-kernel- sized indexes) per fallback-triggering search_symbols call. Implementations: - In-memory Graph: single pass over the byName shard buckets, with short-circuit when limit is reached. - Ladybug Store: one Cypher MATCH with LOWER(n.name) CONTAINS $q LIMIT $k. Ladybug's CONTAINS isn't indexed today, so the cost is still a server-side scan — but the row count crossing cgo is bound to the matching subset rather than the whole node table. - OverlaidView: overlay-touched name hits merged with the masked base call, honouring the same overlaid-file / name-removed filters FindNodesByName applies. - storetest: conformance sub-test populates Login / LoginHandler / Logout / Unrelated and asserts case-insensitive matching, limit honour, empty-needle no-op, and zero-match cleanliness.

The bulkActive flag is per-Store, not per-Indexer — two drains that overlap (warmup parallel-parses 10 repos at a time so this happens regularly) raced on bulkActive and the second caller panicked with "BeginBulkLoad called twice without FlushBulk", killing warmup. Why: warmup drains are concurrent by construction; the prior panic was a latent race that lost on this bench run. How to apply: replace the panic with a per-Store bulkSlot mutex. BeginBulkLoad locks the slot for the full Begin→Flush window; the second caller blocks at the lock instead of panicking. Slot is released right before copyBulkLocked so the next drain's staging window can overlap with the in-flight COPY — COPY-vs-COPY already serialises on writeMu inside copyBulkLocked, so this is safe and trims drain queue latency. --- internal/graph/store_ladybug/store.go | 32 +++++++++++++++++++++++---- 1 file changed, 28 insertions(+), 4 deletions(-) diff --git a/internal/graph/store_ladybug/store.go b/internal/graph/store_ladybug/store.go index 79e6b40..0c14a8c 100644 --- a/internal/graph/store_ladybug/store.go +++ b/internal/graph/store_ladybug/store.go @@ -57,6 +57,15 @@ type Store struct { // call.

On a 122k-node Ladybug DB those cgo round-trips dominate (probe: ~85ms per BM25 call when split four ways; with two BM25 calls per search_symbols, that's ~170ms eaten across calls before the rerank loop even runs). SymbolBundleSearcher folds the post-FTS hops into one bundled call: 4 backend calls per BM25 invocation, but they all run server-side without re-crossing the engine→rerank boundary, AND the bundle's edges pre-seed rerank.Context's outEdgeCache / inEdgeCache so prepare() can skip its own batched fetch. The combined Cypher (FTS + OPTIONAL MATCH + collect + OPTIONAL MATCH + collect) was probed too but Kuzu cross- products the two collect frames — measured 150-185ms median vs the four-query split's 68-90ms. Conformance test in storetest is opt-in: backends that don't implement SymbolBundleSearcher (the in-memory Graph deliberately doesn't — its fallback path stays exercised) skip cleanly. bench/ladybug-bundle-probe is the probe binary used to pick the strategy. --- bench/ladybug-bundle-probe/main.go | 308 ++++++++++++++++++++++++++ internal/graph/store.go | 50 +++++ internal/graph/store_ladybug/fts.go | 124 +++++++++++ internal/graph/storetest/storetest.go | 146 ++++++++++++ 4 files changed, 628 insertions(+) create mode 100644 bench/ladybug-bundle-probe/main.go diff --git a/bench/ladybug-bundle-probe/main.go b/bench/ladybug-bundle-probe/main.go new file mode 100644 index 0000000..3a3a5be --- /dev/null +++ b/bench/ladybug-bundle-probe/main.go @@ -0,0 +1,308 @@ +//go:build ladybug + +// ladybug-bundle-probe: validates candidate Cypher patterns for the +// SymbolBundleSearcher capability — one engine call that returns the +// FTS hit + its full Node row + its in/out edges, so the rerank pipeline +// doesn't have to make 2-3 follow-up cgo round-trips per BM25 fan-out. +// +// Runs against an existing on-disk DB (default /tmp/gortex-daemon-lbug/store.lbug) +// already populated by the daemon.

Plumbing details: * search.SymbolSearcherBackend (the daemon's production text backend adapter) gains SearchSymbolBundles + a SymbolBundleSearcherBackend interface; HybridBackend + Swappable forward when the inner backend supports it. The engine type-asserts through the chain so BM25-only and BM25+vector deployments both pick it up. * QueryOptions gains RerankContext so the MCP search_symbols handler builds rctx BEFORE the BM25 fetch and threads it through; both primary + combined-expansion BM25 calls now seed the same rctx, and the handler-side applyRerankBoosts reads back from it. * SearchTimings gains BundleMS (wall-clock inside SearchSymbolBundles) + CacheHitRate (post-filter candidates whose edges were seeded by the bundle). The bm25_backend_ms derivation subtracts BundleMS so existing fields stay meaningful; the search_symbols debug log surfaces both new fields. * rerank.Context gains SeedEdgeCaches / CachePreSeeded / EdgeCacheHitRate accessors. The cachePreSeeded flag is set by the engine and read by prepare() in the next commit. This commit alone wins on the GetNodesByIDs side (the bundle's nodes replace the post-BM25 batch fetch) but prepare() still nukes the edge caches on its next reset — the full edge-fetch skip lands in the follow-up commit. Net: about a quarter of the rerank cost evaporates already; the rest needs prepare's bypass. --- internal/mcp/tools_core.go | 44 +++++- internal/query/engine.go | 161 ++++++++++++++++++---- internal/query/subgraph.go | 43 +++++- internal/search/hybrid.go | 58 +++++++- internal/search/rerank/context.go | 81 +++++++++++ internal/search/swappable.go | 36 +++++ internal/search/symbolsearcher_backend.go | 42 ++++++ 7 files changed, 428 insertions(+), 37 deletions(-) diff --git a/internal/mcp/tools_core.go b/internal/mcp/tools_core.go index 57ca85a..c0fdfa9 100644 --- a/internal/mcp/tools_core.go +++ b/internal/mcp/tools_core.go @@ -1171,6 +1171,17 @@ func (s *Server) handleSearchSymbols(ctx context.Context, req mcp.CallToolReques } expandedTerms := mergeExpansionTerms(soupFragments, llmTerms, equivTerms) + // Build the rerank context BEFORE the BM25 fetch so the engine's + // bundle path can seed its edge caches as the BM25 calls land. + // The handler-side applyRerankBoostsTimed reuses this same rctx, + // so the merged candidate set's edges are already cached when + // prepare() runs against the post-filter slice.

Today's prepare() unconditionally nukes the cache at the top of the call and re-fires GetInEdgesByNodeIDs + GetOutEdgesByNodeIDs against the candidate set — pure overhead on the bundle path. On Ladybug each batched edge fetch is ~20ms cgo, so skipping both in prepare claws back ~40ms of every search_symbols invocation that goes through the bundle path. prepare() now respects the cachePreSeeded flag the engine set when it seeded bundle edges: the cache survives the reset, and the batched fetch only runs for the IDs NOT already cached (vector hits, fallback substring hits) via the missingEdgeIDs helper. When the bundle covers the full candidate set — the common shape for BM25-only searches — the missing list is empty and no cgo round-trip fires. The fan-in / fan-out max computation moves OUT of the conditional so the stats are derived from whatever cache state we end up with — pre-seeded, fetched, or merged. --- internal/search/rerank/context.go | 83 +++++++++++++++++++++++++++---- 1 file changed, 72 insertions(+), 11 deletions(-) diff --git a/internal/search/rerank/context.go b/internal/search/rerank/context.go index 0eec357..3f8c97f 100644 --- a/internal/search/rerank/context.go +++ b/internal/search/rerank/context.go @@ -247,6 +247,15 @@ func (c *Context) now() int64 { // Ladybug backend each per-candidate GetInEdges / GetOutEdges call // costs ~14ms cgo; batching collapses ~150 round-trips per Rerank // into 2. +// +// Bundle pre-seed fast path: when the caller has set cachePreSeeded +// (via SeedEdgeCaches with preSeeded=true), prepare keeps the existing +// caches in place and skips the batched edge fetch entirely.

SearchSymbolsRanked always ran e.rerank.Rerank() inside the engine, even when called from fetchAndMergeBM25Timed which discards the per-call score order and re-reranks the merged candidate set with the handler's full session-aware Context. Cost: ~165ms per BM25 fan-out × 2 fan-outs = ~330ms wasted. 2. The bundle path used vectorBackend.SearchChannels(query) to pull vector IDs, but SearchChannels re-runs the text BM25 too (HybridBackend.searchChannels fires both channels). The bundle already returned the text hits — paying the FTS Cypher again per BM25 fan-out wastes ~40ms × 2 fan-outs. Why: bench instrumentation showed engine_rerank_ms=330 and discounted text/vec accounting suggested duplicate text pulls; both confirmed by code trace. The merge-side rerank is the source of truth either way. How to apply: - QueryOptions.SkipInnerRerank flag — fetchAndMergeBM25Timed flips it.

When the resulting class is QueryClassSymbol / Path / Signature (and the soup detector hasn't fired), the handler: - forces expand = expandOff so neither the LLM nor the equivalence channel emits expansion terms, and the combined-OR BM25 fan-out in fetchAndMergeBM25 never runs; - sets scope.SkipVectorChannel = true so gatherBackendCandidates skips VectorChannelOnly on the bundle hot path and routes through plain text-only backend.Search on the legacy / fallback path — no embedder call, no ANN search, no SearchChannels. Why: the rerank's classWeightTable (internal/search/rerank/ query_kind.go) already multiplies the semantic signal by 0.65 / 0.45 / 0.80 for these three classes precisely because vector contributes near-zero useful evidence for literal-token queries. The retrieval fan-out was paying for it anyway — a per-call embed + ANN round-trip on the bundle path AND a combined-OR Cypher fan-out from the expansion path — both for results that the rerank then de-weights. On "NewServer" / "handleStreamable" the combined-OR Cypher is the single largest bm25_expansion contributor, and VectorChannelOnly is ~10-20 ms per call. Removing both for identifier queries collapses ~50% of the bm25 round-trips. QueryOptions grows SkipVectorChannel (new) and SkipExactNameSplice (reserved for the dedupe pass) so the engine can be told the calling shape without the caller threading state through arg packs. gatherBackendCandidates now takes the full QueryOptions instead of just SearchTimings — same arity, cleaner contract. A spy backend test asserts an identifier query produces zero VectorChannelOnly calls and zero SearchChannels calls, and that the backend only sees the original query (no combined-OR expansion payload). A negative test confirms a concept query still pulls the vector channel. --- internal/mcp/search_equivalence.go | 16 ++ internal/mcp/tools_core.go | 62 ++++-- internal/mcp/tools_search_fast_path_test.go | 208 ++++++++++++++++++++ internal/query/engine.go | 58 ++++-- internal/query/subgraph.go | 22 +++ 5 files changed, 331 insertions(+), 35 deletions(-) create mode 100644 internal/mcp/tools_search_fast_path_test.go diff --git a/internal/mcp/search_equivalence.go b/internal/mcp/search_equivalence.go index f7f97f8..2b367b2 100644 --- a/internal/mcp/search_equivalence.go +++ b/internal/mcp/search_equivalence.go @@ -54,6 +54,22 @@ func (m expandMode) allowsEquivalenceExpansion() bool { return m == expandBoth || m == expandEquivalenceOnly } +// isIdentifierClass reports whether the query class is one of the +// identifier-shape classes (symbol / path / signature) — the classes +// where the rerank's classWeightTable already proves the semantic +// channel contributes near-zero useful signal (0.65 / 0.45 / 0.80 vs +// the baseline 1.00 for concept).

Skip the exact-name splice on the combined-OR fan-out. gatherBackendCandidates honours a new opts.SkipExactNameSplice flag that suppresses the FindNodesByName(query) Cypher round-trip in the tail of the gather path. fetchAndMergeBM25Timed sets the flag on its combined-OR call — the concatenated bag of expansion terms ("NewServer StartServer Server.Init …") is never going to match any node's literal Name, so the splice was paying a guaranteed- empty cgo round-trip every fan-out. The per-fragment exact-name rescue below still surfaces the PascalCase-fragment cases the splice was insuring against. The primary query keeps the splice on, which is where it actually earns its keep. 2. Tighten the BM25 over-fetch slack on the identifier fast path. The default was offset+limit+10 → typically 30 candidates for a limit=10 query, which gatherBackendCandidates then doubled to 60 on the way into the bundle. With no expansion + no vector channel + no LLM rerank, the only downstream consumer is the structural rerank scoring a single FTS-ranked head; a wide head is wasted work and every extra candidate drags an in/out edge pair through the bundle phase. Tighten to offset+limit+5 (typically 15) for the identifier fast path — the assist / rerank-engaged paths keep the wider window because they actually need the head to reorder. Why: stops two wasted cgo round-trips per identifier search_symbols call and halves the bundle phase's edge load on the common case. The bench's bundle_ms phase carries roughly limit*2 nodes' worth of in/out edges; cutting that down at the source lifts more wall-clock than tuning the per-row work. --- internal/mcp/tools_core.go | 8 ++++++ internal/mcp/tools_search_assist.go | 12 ++++++++- internal/mcp/tools_search_fast_path_test.go | 15 +++++------ internal/query/engine.go | 30 ++++++++++++--------- 4 files changed, 44 insertions(+), 21 deletions(-) diff --git a/internal/mcp/tools_core.go b/internal/mcp/tools_core.go index 5f00a66..59a3197 100644 --- a/internal/mcp/tools_core.go +++ b/internal/mcp/tools_core.go @@ -1187,6 +1187,14 @@ func (s *Server) handleSearchSymbols(ctx context.Context, req mcp.CallToolReques // Slightly widen the BM25 over-fetch when we're going to // rerank: more head candidates means a more useful reorder. fetchLimit = offset + limit + rerankCap + } else if identifierFastPath { + // Identifier-shape fast path: no expansion, no vector channel, + // no LLM rerank — the only down-stream consumer is the + // structural rerank pipeline scoring a single FTS-ranked head. + // A wide head is wasted work; every extra candidate drags an + // in/out edge pair through the bundle phase.

Two backend-naive patterns fed the crash: 1. g.AllEdges() materialised every edge in the graph over cgo (~300k edges × per-Edge struct + meta map). The OOM landed between this allocation and the per-node loop kicking off. buildIfaceRequiredMethods only ever filtered for EdgeImplements — swap to g.EdgesByKind(EdgeImplements) which on Ladybug is one targeted Cypher and on memory is the same shard walk. 2. The per-node g.GetInEdges(n.ID) loop fired one Cypher per node (~133k cgo round-trips, ~1 ms each). Replaced with a single g.GetInEdgesByNodeIDs(nodeIDs) pre-fetch keyed on the full candidate set; the loop then reads from the resulting map. Why: analyze(dead_code) is a production blocker — until this lands the Ladybug daemon dies the first time any agent runs it. How to apply: same pattern as the search hot-path bundle redesign. Pull the data the analyzer actually needs in one round-trip, operate on the map. Avoid the legacy per-element fetch that scales linearly with cgo cost. --- internal/analysis/deadcode.go | 44 +++++++++++++++++++++++++++-------- 1 file changed, 34 insertions(+), 10 deletions(-) diff --git a/internal/analysis/deadcode.go b/internal/analysis/deadcode.go index d90bb97..49edf06 100644 --- a/internal/analysis/deadcode.go +++ b/internal/analysis/deadcode.go @@ -220,13 +220,14 @@ func FindDeadCode(g graph.Store, processes *ProcessResult, excludePatterns []str } nodes := g.AllNodes() - allEdges := g.AllEdges() - // Build set of interface-required method names per type. // If a type implements an interface, all methods that the interface // requires are alive even if never called directly (they satisfy the // contract).

The whole filter is a graph query (nodes of certain kinds with no incoming edges of certain allowed kinds) that the DB has indexes for. These two optional capabilities let backends push the candidate filter + the iface-implements join server-side so the only rows crossing cgo are the surviving ~hundreds of true candidates. Ladybug uses one Cypher per node kind with WHERE NOT EXISTS { MATCH ... } — TestDeadCode_Probe confirmed all three subquery shapes parse, and per-kind is simpler than UNWIND with a map-keyed allowlist.

The whole computation is a graph query the DB has indexes for. When the backend implements DeadCodeCandidator, the WHERE-NOT-EXISTS candidate filter runs server-side and only the surviving ~hundreds of true candidates cross the cgo boundary; the Go side still handles the file-path / build-tag / well-known-name post-filters that need string parsing the engine can't do efficiently. The iface-implements join uses IfaceImplementsScanner the same way — one Cypher instead of NodesByKind + EdgesByKind. Both code paths funnel through the same post-filter loop in FindDeadCode, so callers see the same []DeadCodeEntry contract. Backends without the capabilities (today: the in-memory *Graph also implements them, plus future bbolt / SQLite backends will gain them opt-in) fall through to today's AllNodes + GetInEdgesByNodeIDs path, identical to the pre-Part-2 behaviour. The IncludeFields / IncludeVariables / IncludeConstants opt-in switches now also gate which kinds the candidator scans server-side, so an opt-out kind never crosses cgo for no reason. --- internal/analysis/deadcode.go | 245 +++++++++++++++++++++++++--------- 1 file changed, 179 insertions(+), 66 deletions(-) diff --git a/internal/analysis/deadcode.go b/internal/analysis/deadcode.go index 49edf06..79ca07b 100644 --- a/internal/analysis/deadcode.go +++ b/internal/analysis/deadcode.go @@ -210,6 +210,22 @@ func isEntryPointNode(n *graph.Node) bool { return v } +// candidateNodeKinds enumerates the node kinds FindDeadCode is willing +// to flag (modulo the opt-in switches for fields / variables / +// constants).

129/235] fix(test): align test helpers with graph.Store interface drift Why: SourceReader.Graph() and 24 analyze test helpers still typed their parameter as *graph.Graph, but the production interface tightened to graph.Store; the worktree branch never got the follow-up, so internal/mcp and internal/analysis no longer build with GOWORK=off. --- internal/analysis/scaffold_test.go | 2 +-

With the indexer's bulk-load path binding ~10 string fields per node row across ~70k nodes, this fired ~700k times per warmup — directly responsible for the 215M warmup-time allocation count that survived the prior FlatTuple.GetValue fix. Why: lbug_value_create_string takes ownership of the lbug_value* it returns (caller destroys via lbug_value_destroy), but the C string passed in is copied internally — the Go-side C.CString must be freed by the caller. The original code passed C.CString(v) inline and never held the pointer to free it. goMapToLbugStruct compounded the bug: fieldNames captured one CString that was never freed, while the defer allocated a second CString (for the same key) that went nowhere and leaked instantly. Fix: capture the CString returned by C.CString into a local, hand the pointer to the lbug create_string / fieldNames slice, then defer C.free on that same pointer. --- internal/thirdparty/go-ladybug/value_helper.go | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) diff --git a/internal/thirdparty/go-ladybug/value_helper.go b/internal/thirdparty/go-ladybug/value_helper.go index 6d146b7..1ec5ff0 100644 --- a/internal/thirdparty/go-ladybug/value_helper.go +++ b/internal/thirdparty/go-ladybug/value_helper.go @@ -497,14 +497,15 @@ func goMapToLbugStruct(value map[string]any) (*C.lbug_value, error) { } sort.Strings(sortedKeys) for _, k := range sortedKeys { - fieldNames = append(fieldNames, C.CString(k)) + cName := C.CString(k) + fieldNames = append(fieldNames, cName) + defer C.free(unsafe.Pointer(cName)) lbugValue, error := goValueToLbugValue(value[k]) if error != nil { return nil, fmt.Errorf("failed to convert value in the map with error: %w", error) } fieldValues = append(fieldValues, lbugValue) defer C.lbug_value_destroy(lbugValue) - defer C.free(unsafe.Pointer(C.CString(k))) } var lbugValue *C.lbug_value @@ -607,7 +608,9 @@ func goValueToLbugValue(value any) (*C.lbug_value, error) { case float32: lbugValue = C.lbug_value_create_float(C.float(v)) case string: - lbugValue = C.lbug_value_create_string(C.CString(v)) + cStr := C.CString(v) + lbugValue = C.lbug_value_create_string(cStr) + C.free(unsafe.Pointer(cStr)) case time.Time: if timeHasNanoseconds(v) { lbugValue = C.lbug_value_create_timestamp_ns(timeToLbugTimestampNs(v)) From c0911596f2ba88fdeb597706fde8cd142eaa3bca Mon Sep 17 00:00:00 2001 From: Andrey Kumanyaev Date: Wed, 27 May 2026 03:44:31 +0200 Subject: [PATCH 180/235] chore(ladybug-go): drop test-only deps + unused helper + unused ctx param MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three lint findings left over from vendoring v0.13.1 without its test suite: - go.mod / go.sum referenced testify, davecgh/go-spew, pmezard/go-difflib and yaml.v3 — all test-only.

Move that work behind `gortex enrich releases` / the new `enrich_releases` MCP tool, and turn the analyze handler into a pure graph read over KindRelease nodes + meta.added_in. Missing data returns a structured error pointing at the enricher instead of a silent empty result that looks like "this repo has no releases". The enricher gains a branch filter (default: the repo's default branch via `for-each-ref --merged=`) so topic-branch tags don't pollute the persisted timeline. Mutations re-upsert via g.AddNode so LadyBug-backed daemons persist meta.added_in across restarts. Surfaces: - `gortex enrich releases [path] [--branch] [--snapshot]` — routes through the daemon via the new ControlEnrichReleases RPC when one is up, else falls back to in-memory + optional snapshot. - `enrich_releases` MCP tool — counterpart to enrich_churn for agent- driven refresh. - `gortex githook install --regen-releases [--releases-branch]` — wires the enrich into post-commit / post-merge. - `analyze kind=releases` — optional `tag` param returns the file list whose meta.added_in matches; bare call returns the ordered timeline. releases.EnrichGraph / EnrichGraphWithRepoPrefix stay as thin wrappers over EnrichGraphForBranch with an empty branch so legacy callers keep walking every tag. --- cmd/gortex/daemon_controller.go | 56 +++++++++ cmd/gortex/enrich.go | 72 ++++++++++- cmd/gortex/githook.go | 50 ++++---- internal/daemon/proto.go | 27 +++++ internal/daemon/server.go | 19 +++ internal/daemon/server_test.go | 4 + internal/githooks/install.go | 15 +++ internal/githooks/install_test.go | 24 ++++ internal/hooks/probe_e2e_test.go | 3 + internal/mcp/server.go | 1 + internal/mcp/tools_enhancements.go | 168 ++++++++++++++++++++++---- internal/mcp/tools_enrich_releases.go | 92 ++++++++++++++ internal/mcp/tools_releases_test.go | 119 ++++++++++++++++++ internal/releases/releases.go | 43 ++++++- 14 files changed, 646 insertions(+), 47 deletions(-) create mode 100644 internal/mcp/tools_enrich_releases.go create mode 100644 internal/mcp/tools_releases_test.go diff --git a/cmd/gortex/daemon_controller.go b/cmd/gortex/daemon_controller.go index 74ca451..23db531 100644 --- a/cmd/gortex/daemon_controller.go +++ b/cmd/gortex/daemon_controller.go @@ -19,6 +19,7 @@ import ( "github.com/zzet/gortex/internal/daemon" "github.com/zzet/gortex/internal/graph" "github.com/zzet/gortex/internal/indexer" + "github.com/zzet/gortex/internal/releases" "github.com/zzet/gortex/internal/search" "github.com/zzet/gortex/internal/semantic/lsp" ) @@ -173,6 +174,61 @@ func (c *realController) EnrichChurn(ctx context.Context, p daemon.EnrichChurnPa return combined, nil } +// EnrichReleases runs the per-file release enricher against the +// daemon's graph.

The count-only sibling is a one-row aggregate per direction — the gcx and compact output paths in get_file_summary only emit a total_edges scalar, never per-edge rows, so they reach for it and skip the row-materialisation crossing the cgo boundary. handleGetFileSummary routes accordingly: gcx (non-compact) goes through GetFileSymbolsCounts; compact and json still take the full fetch because they consume edges (compact summarises by confidence, json ships every edge in the body). filterSubGraph + stripFileAndImportNodes preserve sg.TotalEdges when sg.Edges is nil so the count-only payload keeps its header scalar through the filter chain. stripFileAndImportNodes is the new home of the "symbols-only" view the compact path had inline. Every output format (compact, gcx, json, toon) now sees the same shape; the tool description updates the contract accordingly.

The Go-side fileIDIndex turns that into a single RLock + map probe at one string-slot per node. Kept in sync on every mutation path: - AddNode → fileIDIndex.add - addNodesUnwindLocked → fileIDIndex.addNodes - copyBulkLocked → fileIDIndex.addNodes (after dedup, before COPY) - EvictFile → fileIDIndex.removeFile - EvictRepo → look up affected file_paths first, then removeFiles populateFileIDIndexLocked at Open seeds it from on-disk Node rows so a daemon restart against an existing store inherits the index without a re-index pass. GetFileNodes pivots through the accelerator — IN $ids on the PK HASH index instead of the property-filter scan. GetFileSubGraph anchors on the file node's primary key (HASH index) and walks out through EdgeDefines ∪ EdgeContains using the rel-table FROM index. The full-walk shape proved 4-5× faster than the obvious `MATCH (n) WHERE n.id IN $ids` on the same id set — the planner falls back to a node-table scan when the IN-list gets long. GetFileSubGraphCounts is the count-only sibling: two scalar aggregates that pivot off the same file-node walk and report total adjacent edges without materialising any of them. Intra-file edges are counted in both directions; the dedup query (a third 3-pattern join) added more latency than the inflated count costs the gcx caller, who only renders it as a header scalar.

Root-caused and fixed each: - Bulk COPY into an index-bearing table errored mid-COPY, poisoned the pooled connection, and crashed in lbug_connection_destroy. Drop the FTS / vector index before the DELETE+COPY in BulkUpsertSymbolFTS and BulkUpsertEmbeddings; the Build* paths recreate it afterward. - A re-track bulk-COPY'd over already-persisted node rows (duplicate PK SIGSEGV): the shadow-swap firstIndex sentinel is per-Indexer, so it is true on every restart. Evict the repo before the shadow COPY when the store already holds its rows. - EvictRepo only deleted nodes by the repo_prefix column, but edge-endpoint stubs in a repo's namespace (gortex/unresolved::X) are written by mergeStubNodeLocked with an empty repo_prefix. The evict missed them, so a re-track's INSERT-only COPY collided on the leftover stub, failed, and — the repo's real rows already evicted — dropped the whole repo from the graph. Also evict by id-prefix (/). - The first per-edge write to a reopened store hangs forever in lbug_connection_prepare. Route repos that changed during downtime through the shadow/bulk re-track path (HasChangesSinceMtimes) instead of per-edge IncrementalReindex; gated to disk-backed stores so the in-memory backend keeps in-place eviction of offline-deleted files. - Reads racing a COPY faulted: writeMu is now an RWMutex (reads RLock, writes exclusive Lock), so no read runs during a write. Speed: skip the global resolution passes (RunDeferredPassesAll / RunGlobalResolve / graph-wide derivations) and per-repo search-index rebuilds when no file changed — the persisted graph already carries the resolved/derived edges, native FTS, and native HNSW vectors. No-change warm restart drops from 30-500s (+ crash) to ~6s. Also fix a FileMtime primary-key collision: file_id was the bare relative path, so repos sharing paths (src/parser.c, grammar.js across tree-sitter grammars) collided on MERGE and all but the last writer loaded zero mtimes, full-re-indexing (and crash-looping) every restart. Prefix file_id with the repo prefix; strip on load. --- cmd/gortex/daemon_state.go | 97 ++++++++--- internal/graph/store_ladybug/file_mtimes.go | 34 +++- .../store_ladybug/file_mtimes_probe_test.go | 66 +++++++ internal/graph/store_ladybug/fts.go | 13 ++ internal/graph/store_ladybug/store.go | 55 +++++- internal/graph/store_ladybug/vector.go | 11 ++ internal/indexer/indexer.go | 163 ++++++++++++++++-- internal/indexer/multi.go | 56 +++++- 8 files changed, 448 insertions(+), 47 deletions(-) diff --git a/cmd/gortex/daemon_state.go b/cmd/gortex/daemon_state.go index bced996..5874a63 100644 --- a/cmd/gortex/daemon_state.go +++ b/cmd/gortex/daemon_state.go @@ -9,6 +9,7 @@ import ( "sort" "strings" "sync" + "sync/atomic" "time" "go.uber.org/zap" @@ -691,6 +692,15 @@ func warmupDaemonState(state *daemonState, logger *zap.Logger) *indexer.MultiWat jobs := make(chan config.RepoEntry, len(repos)) var wg sync.WaitGroup + // changedRepos counts repos that actually did indexing work this + // warmup: a cold full-track, or a reconcile that re-indexed / evicted + // at least one file.

On the in-memory backend that persists via pointer identity; on disk backends (Ladybug) the node is a per-call GetNode / AllNodes reconstruction, so the stamps were silently discarded, leaving type-aware features and temporal role queries empty on the default backend. These passes run at warmup / via RunGlobalGraphPasses, after the bulk-load buffer is flushed, so the in-place mutation is not captured by the bulk COPY either. Collect the stamped nodes per provider and AddBatch them; stampTemporalRole now takes the store and re-upserts each node. Same write-back idiom as reach / coverage / blame / releases / churn.

The committed darwin dylib and the old download_lbug.sh are removed; .gitignore ignores the fetched lib tree. CI: every job that builds cmd/gortex or runs go test ./... fetches liblbug first (ci.yml test/build-windows/build-onnx, init-smoke), so the link is validated natively on all three OSes. Release: .goreleaser.yml builds the unix targets only (static); a new native-windows job in release.yml builds the dynamic .exe, bundles the runtime DLLs (hard-failing if any is missing), zips, cosign-signs and appends to the release. Scoop manifest is a follow-up (windows is no longer a goreleaser artifact). Validated on darwin: static build is self-contained (no liblbug runtime dep) and the store_ladybug suite passes against the static lib. Linux and windows links are validated by CI on their native runners. --- .github/workflows/ci.yml | 10 ++ .github/workflows/init-smoke.yml | 3 + .github/workflows/release.yml | 112 +++++++++++++ .gitignore | 7 +- .goreleaser.yml | 57 ++----- Makefile | 21 ++- internal/thirdparty/go-ladybug/cgo_shared.go | 32 +++- .../thirdparty/go-ladybug/download_lbug.sh | 79 --------- scripts/fetch-lbug.sh | 151 ++++++++++++++++++ 9 files changed, 340 insertions(+), 132 deletions(-) delete mode 100644 internal/thirdparty/go-ladybug/download_lbug.sh create mode 100755 scripts/fetch-lbug.sh diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index a6b1687..56d85b2 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -20,6 +20,9 @@ jobs: with: go-version: ${{ matrix.go-version }} + - name: Fetch liblbug + run: bash scripts/fetch-lbug.sh + - name: Build run: go build -o gortex ./cmd/gortex/ @@ -47,6 +50,10 @@ jobs: with: go-version: '1.26' + - name: Fetch liblbug (windows dynamic — lbug_shared.dll) + shell: bash + run: bash scripts/fetch-lbug.sh + - name: Build CLI run: go build -o gortex.exe ./cmd/gortex/ @@ -77,6 +84,9 @@ jobs: with: go-version: '1.26' + - name: Fetch liblbug + run: bash scripts/fetch-lbug.sh + - name: Install ONNX Runtime run: | wget -q https://github.com/microsoft/onnxruntime/releases/download/v1.24.4/onnxruntime-linux-x64-1.24.4.tgz diff --git a/.github/workflows/init-smoke.yml b/.github/workflows/init-smoke.yml index 6a6c306..e2bbea9 100644 --- a/.github/workflows/init-smoke.yml +++ b/.github/workflows/init-smoke.yml @@ -29,6 +29,9 @@ jobs: go-version-file: go.mod cache: true + - name: Fetch liblbug + run: bash scripts/fetch-lbug.sh + - name: Build gortex run: go build -o /tmp/gortex ./cmd/gortex diff --git a/.github/workflows/release.yml b/.github/workflows/release.yml index a6b0149..df113b4 100644 --- a/.github/workflows/release.yml +++ b/.github/workflows/release.yml @@ -79,6 +79,18 @@ jobs: chmod 600 "$SIGNING_DIR"/cert.* "$SIGNING_DIR"/notary.* + # Fetch the static liblbug for every unix target into + # lib/static/-/ on the host. $PWD is bind-mounted into the + # goreleaser-cross container, so the cross-compiles below link them + # in (self-contained binaries, nothing to ship alongside).

Open reads schema_version on the raw setup conn (before the pool exists) and applies ordered steps above the stored version: additive ALTERs (ALTER TABLE ... ADD IF NOT EXISTS ..., empirically confirmed against liblbug v0.13.1) preserve the cache; a step that ALTER cannot express (Meta-payload reshape, table restructure) sets a rebuild flag surfaced via NeedsRebuild() so the caller re-indexes. Forward-only — no down migrations; you never roll an embedded derived cache back, you rebuild. Deliberately NOT a golang-migrate/Flyway framework: the graph tables are a re-buildable cache, so this is the embedded-store user_version + switch pattern (~5 small funcs, no deps). The ladder is empty (currentSchema Version=1, the baseline); a pre-versioning DB is detected and stamped v1. Wiring NeedsRebuild() into the daemon warmup lands with the first rebuild-requiring step. --- internal/graph/store_ladybug/migrate.go | 202 +++++++++++++++++++ internal/graph/store_ladybug/migrate_test.go | 202 +++++++++++++++++++ internal/graph/store_ladybug/schema.go | 13 ++ internal/graph/store_ladybug/store.go | 20 +- 4 files changed, 436 insertions(+), 1 deletion(-) create mode 100644 internal/graph/store_ladybug/migrate.go create mode 100644 internal/graph/store_ladybug/migrate_test.go diff --git a/internal/graph/store_ladybug/migrate.go b/internal/graph/store_ladybug/migrate.go new file mode 100644 index 0000000..5993d48 --- /dev/null +++ b/internal/graph/store_ladybug/migrate.go @@ -0,0 +1,202 @@ +package store_ladybug + +// Forward-only schema migration ladder for the Ladybug backend. +// +// The Node/Edge/SymbolFTS/FileMtime tables are a derived cache — every +// row is re-buildable by re-indexing — so this is deliberately NOT a +// golang-migrate / Flyway framework (no up/down files, no rollback, no +// per-instance lock table).

A graded smart_context fanning this over hub symbols hung for minutes and grew the heap into the tens of GB while holding the store, freezing concurrent reads (and daemon status). Add an optional graph.FrontierExpander capability implemented by the ladybug store: one Cypher per BFS level returns the frontier's edges of the requested kinds plus the neighbour node columns, meta-free, with a server-side LIMIT (frontierRowCap) and unresolved/external targets filtered in-query. Rewrite bfs to use it for directed walks (the in-memory backend and bidirectional/overlay walks keep the per-node path), cap allEdges by the node limit, drop the duplicate per-neighbour GetNode, and re-hydrate full-detail neighbours in one batched GetNodesByIDs. A 2000-fan-in hub now returns GetCallers as 64 nodes / 63 edges in ~16ms; a live multi-repo graded smart_context that previously hung at ~40 GB returns in seconds at a flat ~4.8 GB footprint. Covered by frontier_test.go (Cypher correctness) and frontier_scale_test.go (bounding). Also fix two pre-existing errcheck issues (unchecked Store.Close) in migrate_test.go. --- internal/graph/store.go | 27 +++ .../store_ladybug/frontier_scale_test.go | 70 ++++++ internal/graph/store_ladybug/frontier_test.go | 144 ++++++++++++ internal/graph/store_ladybug/migrate_test.go | 4 +- internal/graph/store_ladybug/store_read.go | 71 ++++++ internal/graph/store_ladybug/store_rows.go | 50 ++++ internal/query/engine.go | 214 +++++++++++------- 7 files changed, 495 insertions(+), 85 deletions(-) create mode 100644 internal/graph/store_ladybug/frontier_scale_test.go create mode 100644 internal/graph/store_ladybug/frontier_test.go diff --git a/internal/graph/store.go b/internal/graph/store.go index c36d08d..9752377 100644 --- a/internal/graph/store.go +++ b/internal/graph/store.go @@ -1489,6 +1489,33 @@ type FileSubGraphReader interface { GetFileSubGraph(filePath string) (nodes []*Node, edges []*Edge) } +// FrontierHop is one (edge, neighbour) pair from a FrontierExpander: an +// edge adjacent to a queried source node plus the node at its far end, +// with the neighbour's columns populated and Meta left nil (traversal +// callers don't read it).

DELIM=\t' reads. A node id carrying a raw tab or newline — e.g. a ws:: WebSocket-contract node (fmt.Sprintf("ws::%s", event) over a raw regex submatch) or a string-literal-derived node — split the physical row, so the continuation line had a single field and the COPY aborted the whole batch with "expected 2 values per row, but got 1". The vector index for that batch was silently lost. Route the id through sanitizeTSV (tab/CR/LF -> space), the same canonicalisation writeNodesTSV and copyBulkLocked already apply to the Node primary key, so SymbolVec.id stays byte-equal to the persisted Node.id and the SimilarTo join still matches. A lossless escape would be wrong here: it would round-trip the raw newline back into SymbolVec.id, breaking the join against the sanitized Node id.

Kuzu COPY into a node table is only legal into an empty table or one that already carries a materialized PK hash index; DELETE empties rows logically but leaves the table non-empty for COPY, and whether the PK hash index is present at COPY time depends on uncontrolled auto-checkpoint timing. So the 2nd+ bulk upsert failed non-deterministically with 'COPY into a non-empty primary-key node table without a hash index is not supported'. It fires in production on any reindex / warm-restart reconcile that re-enters buildSearchIndex, not just tests. SymbolVec is uniquely exposed: it is the only PK table created lazily right before its first COPY (absent from the static schema DDL), so its PK index isn't checkpointed by warmup the way Node/Edge/SymbolFTS are. Drop the vector index first (DROP TABLE has no cascade and is rejected while the HNSW index references the table), then DROP TABLE IF EXISTS, reset s.vec.dim to 0 so ensureSymbolVecSchemaLocked recreates instead of short-circuiting on cur==dim, recreate the table, and COPY into the fresh empty table — an empty table is unconditionally a valid COPY target, so the racy state class is removed. Pool-safe: each statement borrows its own pooled connection, serialized by the writeMu write lock held across the call. Also drop the index before DROP TABLE in ensureSymbolVecSchemaLocked's dim-change branch (same latent index-reference hazard). vector_recopy_test.go loops the wipe-and-rewrite (bulk -> BuildVectorIndex -> bulk -> ...) in one store. Pre-fix the full -tags ladybug vector suite at -count=8 produced 16 failures; post-fix it is 48/48 (and 36/36 under -race). These vector tests are //go:build ladybug and not in the default 'make test' gate, which is why the flake went unnoticed. Note: BulkUpsertSymbolFTS shares the same DELETE-then-COPY hazard but its per-repo clear in multi-repo mode means DROP TABLE is unsafe there (would wipe sibling repos); that path needs a separate remedy and is left for a follow-up. --- internal/graph/store_ladybug/vector.go | 22 +++++++-- .../graph/store_ladybug/vector_recopy_test.go | 49 +++++++++++++++++++ 2 files changed, 68 insertions(+), 3 deletions(-) create mode 100644 internal/graph/store_ladybug/vector_recopy_test.go diff --git a/internal/graph/store_ladybug/vector.go b/internal/graph/store_ladybug/vector.go index 51ad286..3e6196d 100644 --- a/internal/graph/store_ladybug/vector.go +++ b/internal/graph/store_ladybug/vector.go @@ -69,7 +69,10 @@ func (s *Store) ensureSymbolVecSchemaLocked(dim int) error { if cur != 0 { // Dim changed (e.g. different embedding model on this // fresh daemon process).

MERGE so a non-empty per-repo COPY can't be rejected MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BulkUpsertSymbolFTS cleared the corpus then COPYed it back. In multi-repo mode the clear is per-repo (MATCH (f) WHERE f.id STARTS WITH $p DELETE f) and intentionally keeps sibling repos' rows, so SymbolFTS is non-empty by design. Kuzu COPY into a node table is only legal when the table is empty or already carries a materialized PK hash index, whose presence depends on auto-checkpoint timing, so the COPY failed non-deterministically with 'COPY into a non-empty primary-key node table without a hash index is not supported'. This is the same class as the SymbolVec re-COPY bug and fires on multi-repo reindex / warm-restart reconcile, but DROP TABLE + recreate (the SymbolVec remedy) is unsafe here — it would wipe the sibling repos. Replace the COPY with a single 'LOAD FROM (header=false, delim=tab) MERGE (f:SymbolFTS {id: column0}) SET f.tokens = column1'. LOAD FROM scans the file as a row source and MERGEs straight into SymbolFTS — a DML write with no empty-table precondition — in one statement, no staging table. Measured on a 20k-row corpus (liblbug 0.17.0): direct COPY into empty 74ms; staging COPY-into-temp + MERGE 193ms; LOAD FROM + MERGE 91ms. So it is ~2x faster than staging and within ~23% of a raw COPY while removing the rejection entirely. (CHECKPOINT before COPY was tried and made it deterministically worse, 8/8 fail.) fts_recopy_test.go drives the per-repo non-empty re-bulk repeatedly (pre-fix the full -tags ladybug run at -count=4 failed 3/4; deterministic after). fts_timing_test.go is the 3-way COPY/staging/LOAD-FROM perf comparison.

But restart's readiness loop polled daemon.IsRunning(), i.e. socket reachability, and the socket is torn down well before the process exits and the lock clears. So the new daemon opened the store while the old one still held the lock, and liblbug refused with its single generic status (lbug_state is just Success/Error, and lbug_database_init exposes no error string — so the message was unrecoverable). - daemon.RunningPID(): PID-file liveness probe (newline-tolerant) that, unlike IsRunning, still reports a daemon whose socket is gone but whose process and store lock are still alive — the exact restart window. - runDaemonStop captures the PID and waitForDaemonExit blocks until the process has actually exited (15s graceful, then SIGKILL + socket/PID cleanup), so "stopped" now means the lock is released. - runDaemonRestart drops the socket-poll loop and relies on the blocking stop. - runDaemonStart refuses early with "daemon already running (pid N)" instead of letting the backend open die on the lock; openLadybugBackend wraps the bare status with an actionable hint.
