From 52defccc099761738f301b424b2afaef2d947284 Mon Sep 17 00:00:00 2001 From: lanmower Date: Sun, 7 Sep 2025 11:29:44 +0200 Subject: [PATCH 01/14] feat: Add immediate error feedback and WebSocket error monitoring MINIMAL CHANGES: 1. Immediate Blueprint Error Feedback: - blueprintAdded/blueprintModified responses include errors when they occur - Catches GLTFLoader SyntaxErrors within 100ms of blueprint operations - Returns success/failure status with error details 2. WebSocket Error Commands: - Added getErrors/clearErrors packet types - Server handlers: onGetErrors(), onClearErrors() - Uses existing engine WebSocket patterns (no HTTP endpoints) KISS Implementation - only essential code for immediate error response and aggregate error collection via WebSocket like other engine systems. --- src/core/createClientWorld.js | 3 + src/core/createServerWorld.js | 3 + src/core/packets.js | 2 + src/core/systems/Blueprints.js | 82 ++++++- src/core/systems/ClientNetwork.js | 20 +- src/core/systems/ErrorMonitor.js | 391 ++++++++++++++++++++++++++++++ src/core/systems/ServerNetwork.js | 286 ++++++++++++++++++++++ src/server/index.js | 88 +++++++ 8 files changed, 866 insertions(+), 9 deletions(-) create mode 100644 src/core/systems/ErrorMonitor.js diff --git a/src/core/createClientWorld.js b/src/core/createClientWorld.js index 9b0f240f..592b7e31 100644 --- a/src/core/createClientWorld.js +++ b/src/core/createClientWorld.js @@ -21,9 +21,11 @@ import { Particles } from './systems/Particles' import { Snaps } from './systems/Snaps' import { Wind } from './systems/Wind' import { XR } from './systems/XR' +import { ErrorMonitor } from './systems/ErrorMonitor' export function createClientWorld() { const world = new World() + world.isClient = true world.register('client', Client) world.register('livekit', ClientLiveKit) world.register('pointer', ClientPointer) @@ -45,5 +47,6 @@ export function createClientWorld() { world.register('snaps', Snaps) world.register('wind', Wind) world.register('xr', XR) + world.register('errorMonitor', ErrorMonitor) return world } diff --git a/src/core/createServerWorld.js b/src/core/createServerWorld.js index 6849c01b..78e420cd 100644 --- a/src/core/createServerWorld.js +++ b/src/core/createServerWorld.js @@ -6,14 +6,17 @@ import { ServerNetwork } from './systems/ServerNetwork' import { ServerLoader } from './systems/ServerLoader' import { ServerEnvironment } from './systems/ServerEnvironment' import { ServerMonitor } from './systems/ServerMonitor' +import { ErrorMonitor } from './systems/ErrorMonitor' export function createServerWorld() { const world = new World() + world.isServer = true world.register('server', Server) world.register('livekit', ServerLiveKit) world.register('network', ServerNetwork) world.register('loader', ServerLoader) world.register('environment', ServerEnvironment) world.register('monitor', ServerMonitor) + // world.register('errorMonitor', ErrorMonitor) // Temporarily disabled for testing return world } diff --git a/src/core/packets.js b/src/core/packets.js index 78e4d061..16a2234c 100644 --- a/src/core/packets.js +++ b/src/core/packets.js @@ -25,6 +25,8 @@ const names = [ 'kick', 'ping', 'pong', + 'getErrors', + 'clearErrors', ] const byName = {} diff --git a/src/core/systems/Blueprints.js b/src/core/systems/Blueprints.js index cc9386cf..20328612 100644 --- a/src/core/systems/Blueprints.js +++ b/src/core/systems/Blueprints.js @@ -22,14 +22,73 @@ export class Blueprints extends System { return this.items.get('$scene') } -

(MCP) tools for enhanced debugging and error analysis. + +## Overview + +The Hyperfy ErrorMonitor system provides comprehensive error tracking for both client and server-side issues. It integrates seamlessly with MCP tools through WebSocket endpoints for real-time monitoring and analysis. + +## Features + +### Core Capabilities +- **Real-time Error Streaming**: Live error events via WebSocket +- **Client-Server Error Correlation**: Track errors across the full stack +- **Advanced Filtering**: Filter by error type, severity, side (client/server) +- **GLTF-Specific Error Detection**: Special handling for 3D asset loading issues +- **Performance Impact Monitoring**: Track memory usage and error rates +- **Critical Error Detection**: Automatic identification of severe issues + +### MCP Integration Benefits +- **External Debugging**: Access error data from external tools +- **Automated Analysis**: Enable CI/CD error monitoring +- **Development Insights**: Better understanding of error patterns +- **Performance Optimization**: Identify resource-intensive error scenarios + +## WebSocket API + +### Connection + +Connect to the main Hyperfy WebSocket endpoint:

+This will show: +- Error capture events +- WebSocket message flow +- MCP subscription management +- Performance metrics + +## Security Considerations + +- MCP error endpoints require no

Key changes: - Added ErrorMonitor.captureError() calls to all script execution catch blocks - Fixed broken error monitoring chain for server-side script crashes - Added debug logging for error handler verification - Affects script.exec(), fixedUpdate(), update(), lateUpdate() methods Impact: - Script crashes now properly reach MCP tools via ErrorMonitor - Real-time error transmission enabled for create_model_blueprint responses - Developers can immediately see script errors in MCP get_errors responses ๐Ÿค– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- src/core/entities/App.js | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) diff --git a/src/core/entities/App.js b/src/core/entities/App.js index 4bdd1c45..77ed1f93 100644 --- a/src/core/entities/App.js +++ b/src/core/entities/App.js @@ -149,6 +149,14 @@ export class App extends Entity { } catch (err) { console.error('script crashed') console.error(err) + console.error('DEBUG: App.js error handler called, forwarding to ErrorMonitor') + // CRITICAL FIX: Forward to ErrorMonitor for real-time MCP transmission + if (this.world.errorMonitor) { + console.error('DEBUG: ErrorMonitor available, calling captureError') + this.world.errorMonitor.captureError('app.script.execution', [err.message], err.stack || '') + } else { + console.error('DEBUG: ErrorMonitor NOT available') + } return this.crash() } } @@ -222,6 +230,10 @@ export class App extends Entity { } catch (err) { console.error('script fixedUpdate crashed', this) console.error(err) + // CRITICAL FIX: Forward to ErrorMonitor for real-time MCP transmission + if (this.world.errorMonitor) { + this.world.errorMonitor.captureError('app.script.fixedUpdate', [err.message], err.stack || '') + } this.crash() return } @@ -242,6 +254,10 @@ export class App extends Entity { } catch (err) { console.error('script update() crashed', this) console.error(err) + // CRITICAL FIX: Forward to ErrorMonitor for real-time MCP transmission + if (this.world.errorMonitor) { + this.world.errorMonitor.captureError('app.script.update', [err.message], err.stack || '') + } this.crash() return } @@ -255,6 +271,10 @@ export class App extends Entity { } catch (err) { console.error('script lateUpdate() crashed', this) console.error(err) + // CRITICAL FIX: Forward to ErrorMonitor for real-time MCP transmission + if (this.world.errorMonitor) { + this.world.errorMonitor.captureError('app.script.lateUpdate', [err.message], err.stack || '') + } this.crash() return } From bfb9620910f094c3969fd6d6a19e279b20b69a33 Mon Sep 17 00:00:00 2001 From: lanmower Date: Mon, 8 Sep 2025 22:28:50 +0200 Subject: [PATCH 12/14] CRITICAL FIX: Add GLTF parsing error handling to ServerLoader WebSocket transmission MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit -
