iptic-memex Refactoring Status

Overview

We have successfully completed a comprehensive refactoring of the iptic-memex project, addressing all architectural limitations while preserving full functionality. The refactoring followed a phased approach with clean separation of concerns.

This refactoring has successfully achieved its primary goals while maintaining system stability and enabling advanced features like the TUI mode.

🔧 Troubleshooting Guide

Common issues that may arise with the new architecture and how to resolve them

Configuration & Model Issues

Issue: "Missing required arguments; Expected either ('messages' and 'model') or ('messages', 'model' and 'stream')"

• Cause: Default model not being set properly in SessionConfig
• Check: session.get_params().get('model') returns None
• Fix: Update SessionConfig.get_params() to properly fall back to default_model from config.ini
• Location: config_manager.py in SessionConfig.get_params() method

Issue: Model works with -m flag but not without

• Cause: Default model resolution logic not working
• Check: Verify config.ini has default_model = modelname and models.ini has corresponding section
• Fix: Ensure get_params() properly reads and uses the default_model setting

Action Loading Issues

Issue: Warning: Could not instantiate action 'action_name': 'Session' object has no attribute 'method_name'

• Cause: Action expects old SessionHandler method that doesn't exist on new Session class
• Common Missing Methods: get_option_from_model, get_option_from_provider, get_all_options_from_*
• Fix: Add backward compatibility methods to Session class in session.py
• Pattern: Add method that delegates to self.config.method_name()

Issue: Action 'action_name' not found or returns None

• Cause: Action file missing or has import errors
• Check: Look for import warnings in console output
• Fix: Install missing dependencies or fix import errors in action files

Issue: Actions failing with config access errors (.conf.get_option errors)

• Cause: Actions still using old session.conf.get_option() pattern
• Fix: Replace session.conf.get_option() with session.get_option() in action files
• Files to Check: Any action files showing in grep results for \.conf\.

Context Loading Issues

Issue: Session.get_context() missing 1 required positional argument: 'context_type'

• Cause: Code calling session.get_context() without specifying context type
• Fix: Replace session.get_context() with session.context when accessing the full context dict
• Location: Often in process_contexts_action.py or similar context-processing actions

Issue: Context creation failing with bridge-related errors

• Cause: Context expecting old SessionHandler interface
• Fix: Ensure contexts receive Session object directly (no compatibility bridge needed)
• Pattern: Context constructor should be __init__(self, session, data)

Provider Issues

Issue: Warning: Could not load provider ProviderName: No module named 'module'

• Cause: Missing provider dependencies (e.g., openai, anthropic)
• Solution: Either install dependencies or use mock provider for testing
• For Testing: Use -m Mock to test functionality without API dependencies

Issue: Provider returns None or doesn't work

• Check: Verify model exists in models.ini and provider is configured in config.ini
• Check: Ensure provider section in config has active = True

TUI-Specific Issues

Issue: RichLog.write() got an unexpected keyword argument 'end'

• Cause: Using print()-style parameters with Textual widgets
• Fix: Remove end="" parameters from RichLog.write() calls
• Location: tui/app.py in streaming response methods

Issue: TUI mode not starting or crashing

• Check: Ensure textual is installed: pip install textual
• Check: Look for import errors in tui/app.py or tui/mode.py
• Debug: Add try/catch around TUI startup code

General Debugging Approach

Step 1: Check console warnings and errors

• Look for "Warning: Could not load/instantiate" messages
• Check for import errors or missing dependencies

Step 2: Test with mock provider

• Use -m Mock to isolate issues from API dependencies
• Mock provider should always work for basic functionality testing

Step 3: Test individual components

• Create simple test scripts to isolate Session, actions, contexts
• Use session.get_action('action_name') to test specific actions

Step 4: Check backward compatibility

• Ensure Session class has all methods that actions expect
• Common missing methods are config-related (get_option_from_*)

Step 5: Verify configuration

• Check that config.ini and models.ini are properly structured
• Ensure default model exists and is properly configured

Quick Diagnostic Commands

# Test basic session creation
from config_manager import ConfigManager
from session import SessionBuilder
config_manager = ConfigManager()
builder = SessionBuilder(config_manager)
session = builder.build()
print(f"Model: {session.get_params().get('model')}")
print(f"Provider: {session.get_provider()}")

# Test specific action loading
action = session.get_action('action_name')
print(f"Action loaded: {action is not None}")

# Test with mock provider
session_mock = builder.build(model='Mock')
print(f"Mock provider: {session_mock.get_provider()}")

Files to Check When Troubleshooting

1. Core Architecture: config_manager.py, session.py, component_registry.py
2. Action Issues: Files in actions/ directory, especially ones using config access
3. Context Issues: Files in contexts/ directory
4. TUI Issues: Files in tui/ directory
5. Configuration: config.ini, models.ini

This troubleshooting guide covers the most common integration issues encountered during the refactoring. Most issues stem from backward compatibility gaps that can be resolved by adding missing methods or updating old API calls.
