Adds expression index on lower(name) for memory-efficient case-insensitive searches, replacing in-memory caches that caused OOM on large codebases. Includes batched reference resolution, enhanced error reporting with detailed breakdown by error type, and improved CLI progress display for scanning phases.
Replace native tree-sitter with web-tree-sitter + tree-sitter-wasms for
universal cross-platform support. Add node-sqlite3-wasm as a fallback
when better-sqlite3 native bindings aren't available. Move better-sqlite3
and sqlite-vss to optionalDependencies so installs never fail.
Fix installer to use npx fallback when global npm install fails, so MCP
config, hooks, and quick-start instructions all work without the bare
codegraph command in PATH.
Fix tests: update schema version expectation, fix db test paths and
method names, extract MAX_OUTPUT_LENGTH as module constant, normalize
Windows path separators in import resolver.
- Add provenance column on edges for tracking how edges were created
- Add project_metadata table for version/provenance tracking
- Make unresolved_refs file_path/language NOT NULL with defaults
- Add composite indexes for unresolved_refs and edges.provenance
- Update v2 migration to handle all new schema additions
- Record schema version on initialize to prevent re-migration
- Add dynamic prepared statement cache (getDynamicStmt) for varying SQL
- Add batch methods: getNodesByIds, getNodesByKinds, getFileHashMap, getFileSyncMap
- Add project metadata methods: getMetadata, setMetadata, getAllMetadata
- Optimize getStats to use single aggregate query
- Optimize getStaleFiles to use temporary table JOIN
- Add provenance parameter to getOutgoingEdges
- Add intent field to SearchOptions type
- SQLite performance pragmas: synchronous=NORMAL, 64MB cache,
memory temp store, 256MB mmap (safe with WAL mode)
- Batch insert for unresolved refs: single transaction instead of
N individual inserts per file
- Symbol caching (warmCaches): pre-load all nodes into memory maps
before resolution, eliminating repeated SQLite queries per ref
- Async file I/O: fs.stat/readFile in indexFile() are now non-blocking
- Denormalize filePath/language onto UnresolvedReference: avoids N
node lookups during resolution, with schema migration v2
