Gergő Magyar	3f0c74fea0	fix(deps): upgrade @ladybugdb/core to 0.16.0 to resolve native segfaults (#1235) ... * fix(deps): upgrade @ladybugdb/core to 0.16.0 to resolve native segfaults Resolves the SIGSEGV / access-violation (0xC0000005) / exit-139 crashes that have been reported widely since 1.6.3. The native crashes originate in @ladybugdb/core 0.15.x — primarily during FTS index creation, VECTOR extension load, and concurrent query teardown — and are reproducible on Linux, macOS and Windows. The maintainer-confirmed fix is to bump the runtime to 0.16.0, which ships nodejs async + memory-management fixes, extension ABI bump, and macOS Intel binaries. Adopting 0.16.0 cleanly required three supporting changes; without them the upgrade itself regresses other paths: 1. maxDBSize must be passed explicitly. 0.16.0 keeps the upstream JSDoc note that the default 0 is "introduced temporarily for now to get around with the default 8 TB mmap address space limit some environment". Constrained CI runners and laptops cannot reserve 8 TB and crash with "Buffer manager exception: Mmap for size 8796093022208 failed." A new gitnexus/src/core/lbug/lbug-config.ts centralises a 16 GiB default (overridable via GITNEXUS_LBUG_MAX_DB_SIZE) and every Database() construction site now passes it. 2. enableCompression default flipped from false to true in 0.16.0. Every Database() call site is updated to pass false explicitly so existing GitNexus indexes keep the same wire format. 3. Bridge DB sidecar files (.wal, .shadow). 0.16.0 enforces a database-id check on .wal / .shadow sidecars and rejects opens whose sidecars belong to a different base name. writeBridge now (a) cleans the full sidecar set when removing the tmp slot, (b) renames .wal / .shadow alongside the main file during the atomic .tmp -> .lbug swap, and (c) wraps openBridgeDbReadOnly in a bounded retry on transient Win32-Error-33 lock errors. Eager db.init() / conn.init() forces the lazy native handle to surface lock contention at the retry site. Known limitation (not a regression): on Windows the 0.16.0 native binary does not release the OS file lock until the process exits, so the close-then-reopen-same-process pattern raises Error 33 after the first close. Production paths (analyze / serve / mcp each open the DB exactly once per process) are unaffected, but eight tests that exercise the pattern are guarded with a process.platform === 'win32' skip; CI's Linux + macOS shards exercise them as before. Tracking upstream: kuzudb/kuzu#3872 / #3883 / #4730. Closes #1136 #1154 #1160 #1162 #1178 #1195 #1196 #1199 #1204 #1206 Refs #1209 (supersedes — Dependabot bump without the supporting fixes) Made-with: Cursor * fix(test): isolate LadybugDB native test state Use per-suite LadybugDB databases in integration helpers so test forks do not reopen a database created by Vitest global setup, and centralize Windows-tolerant native temp cleanup for bridge tests. * fix(lbug): avoid bridge existence reopen Reuse the built LadybugDB config in the extension installer and avoid native close/reopen cycles when checking bridge existence on Windows. Made-with: Cursor * chore(docs): exclude local lbug plan Keep the refactor planning note out of the PR while leaving the ignored local copy on disk. Made-with: Cursor * refactor(lbug): centralize database construction Route LadybugDB opens through shared helpers so native constructor defaults stay consistent across core, pool, bridge, and extension install paths.

Gergő Magyar	ffa0510f9a	fix(lbug): prevent DuckDB extension install hangs (#1129) ... * fix(lbug): bound DuckDB extension install via ExtensionManager (closes #1128) `gitnexus analyze` could hang indefinitely (60% / 85% on Windows) when DuckDB's `INSTALL fts` or `INSTALL VECTOR` was unable to reach `extensions.duckdb.org`. The DuckDB driver's INSTALL is a synchronous network call, so any blocked egress would block the Node event loop forever. Replace the ad-hoc, in-process INSTALL/LOAD scattered across `lbug-adapter.ts` and `pool-adapter.ts` with a single `ExtensionManager` that owns the lifecycle of optional DuckDB extensions: * `LOAD` is always tried first — per-connection, idempotent, no network. * If `LOAD` fails and policy permits, INSTALL runs in a short-lived child Node process bounded by `GITNEXUS_LBUG_EXTENSION_INSTALL_TIMEOUT_MS` (default 15s). The parent loop keeps spinning; on timeout the child is killed with SIGKILL and the capability is flagged unavailable. * Capabilities and install attempts are cached per process, so a single bounded install per extension covers every subsequent call. Install policy is now an explicit, per-context decision: * `auto` (default for analyze) — try LOAD, fall back to bounded INSTALL. * `load-only` — used by `pool-adapter` (serve / MCP read paths) so user queries never block on a network install. * `never` — operator escape hatch for offline / airgapped environments. `createFTSIndex` and `createVectorIndex` now check the boolean return value before issuing the index DDL, so missing extensions degrade BM25 and semantic search gracefully without ever throwing during analyze. Tests: - New unit suite for `ExtensionManager` covering LOAD-first behavior, all three policies, install caching, observability, and warn dedup. - Existing vector-extension integration tests pass against the new boolean return type. - Existing embedding-pipeline mocks updated to return `true`. Docs: `gitnexus/README.md` documents `GITNEXUS_LBUG_EXTENSION_INSTALL` and `GITNEXUS_LBUG_EXTENSION_INSTALL_TIMEOUT_MS` with examples for offline and slow-network environments. Made-with: Cursor * fix(lbug): move DuckDB extension install child into script Keep the bounded out-of-process INSTALL behavior, but replace the inline child code with a stable packaged ESM script. This makes the child process directly runnable and gives debuggable stack traces without source-vs-dist branching or a runtime transpiler. Made-with: Cursor	2026-04-27 23:09:17 +01:00
