# File-WatchConfig Bidirectional Relationships Implementation ## Overview Implemented bidirectional relationships between `WatchConfig` and `File` nodes to track which files belong to which watch configurations. ## Relationships Created ### WatchConfig → File - **Relationship**: `[:WATCHES]` - **Direction**: `(WatchConfig)-[:WATCHES]->(File)` - **Meaning**: A WatchConfig monitors this File ### File → WatchConfig - **Relationship**: `[:WATCHED_BY]` - **Direction**: `(File)-[:WATCHED_BY]->(WatchConfig)` - **Meaning**: This File is monitored by a WatchConfig ## Implementation Details ### 1. File Creation (FileIndexer.ts) - Modified `indexFile()` to accept optional `watchConfigId` parameter - When `watchConfigId` is provided, creates both relationships: ```cypher MATCH (wc:WatchConfig {id: $watchConfigId}) MERGE (wc)-[:WATCHES]->(f) MERGE (f)-[:WATCHED_BY]->(wc) ``` ### 2. File Indexing (FileWatchManager.ts) - Updated `indexFolder()` to pass `config.id` when indexing files - Updated `handleFileAdded()` to pass `config.id` for new files - Both methods now create relationships automatically ### 3. File Deletion - **Individual file deletion**: `DETACH DELETE` in `deleteFile()` automatically removes all relationships - **Folder removal**: `DETACH DELETE` in `handleRemoveFolder()` removes all files and their relationships ## Benefits 1. **Orphan Detection**: Easy to find files without watch configs ```cypher MATCH (f:File) WHERE NOT EXISTS { MATCH (f)<-[:WATCHES]-(wc:WatchConfig) } RETURN f ``` 2. **Watch Cleanup**: When removing a watch, can find all associated files ```cypher MATCH (wc:WatchConfig {id: $id})-[:WATCHES]->(f:File) RETURN f ``` 3. **File Provenance**: Can trace which watch config indexed a file ```cypher MATCH (f:File {path: $path})-[:WATCHED_BY]->(wc:WatchConfig) RETURN wc ``` ## Testing ### Verify Relationships After Indexing ```cypher MATCH (wc:WatchConfig)-[:WATCHES]->(f:File) RETURN wc.path, count(f) as file_count ``` ### Check for Orphaned Files ```cypher MATCH (f:File) WHERE NOT EXISTS { MATCH (f)<-[:WATCHES]-(wc:WatchConfig) } RETURN count(f) as orphaned_count ``` ### Verify Bidirectional Relationships ```cypher MATCH (wc:WatchConfig)-[:WATCHES]->(f:File)-[:WATCHED_BY]->(wc2:WatchConfig) WHERE wc <> wc2 RETURN count(*) as mismatched_relationships // Should return 0 ``` ## Migration Existing files without relationships will remain orphaned until: 1. The file is modified (triggers re-indexing with relationship) 2. The folder is re-indexed manually 3. A cleanup script is run to remove orphaned files ## Files Modified 1. `src/indexing/FileIndexer.ts` - Added `watchConfigId` parameter to `indexFile()` - Added relationship creation in File node query 2. `src/indexing/FileWatchManager.ts` - Pass `config.id` in `indexFolder()` - Pass `config.id` in `handleFileAdded()` 3. No changes needed for deletion (already handled by `DETACH DELETE`) ## Update: Fixed WatchConfig Creation ### Issue Found The WatchConfig nodes were being created with only the `path` (container path) but not the `host_path`. This is needed for proper path translation and user-facing displays. ### Fix Applied Updated `handleIndexFolder()` in `fileIndexing.tools.ts` to include `host_path` when creating WatchConfig: ```typescript const input: WatchConfigInput = { path: containerPath, // Container path for internal use host_path: resolvedPath, // Host path for user display recursive: params.recursive ?? true, // ... other properties }; ``` ### Why This Matters - **Container path** (`/workspace/...`): Used internally for file matching - **Host path** (`/Users/...`): Shown to users, used for path translation - Both paths are now stored in WatchConfig for complete path tracking ### Complete Flow 1. User provides host path: `/Users/c815719/src/project` 2. Translated to container path: `/workspace/project` 3. WatchConfig created with BOTH paths 4. Files indexed with container paths 5. Relationships created: `(WatchConfig)-[:WATCHES]->(File)` 6. File paths match WatchConfig container path ✅
