This commit fixes three critical issues identified in CI/CD and adds comprehensive test coverage for the new multi-user functionality. ## Fixes ### 1. FastMCP Middleware Registration Error **Problem**: `AttributeError: 'FastMCP' object has no attribute 'app'` **Solution**: Implemented robust middleware registration that: - Tries multiple possible locations where FastMCP might store the app - Gracefully handles cases where app isn't immediately available - Wraps the run() method to defer middleware addition if needed - Attempts: _transport.app, sse.app, http_server.app, _app, _asgi_app - Falls back gracefully with warning if middleware can't be added **Files Changed**: - src/geoguessr_mcp/main.py: Added smart middleware registration logic ### 2. Test Permission Errors **Problem**: `PermissionError: [Errno 13] Permission denied: '/app'` Schema registry tried to create /app/data/schemas in CI without permission **Solution**: Made schema cache directory creation fault-tolerant: - Catches PermissionError and OSError when creating cache directory - Falls back to temporary directory (tempfile.mkdtemp) if permission denied - Logs clear warning messages about fallback behavior - Tests can now run in restricted environments **Files Changed**: - src/geoguessr_mcp/monitoring/schema/schema_registry.py: Added fallback logic ### 3. Black Formatting Issues **Problem**: 10 files needed reformatting **Solution**: Ran `black src/ --line-length 100` on all source files **Files Formatted**: - src/geoguessr_mcp/config.py - src/geoguessr_mcp/api/dynamic_response.py - src/geoguessr_mcp/middleware/auth.py - src/geoguessr_mcp/main.py - src/geoguessr_mcp/auth/multi_user_session.py - src/geoguessr_mcp/tools/auth_tools.py - src/tests/integration/test_auth_flow.py - src/tests/unit/services/*.py (3 files) ## New Tests Added comprehensive test coverage for multi-user features: ### test_user_context.py - Tests UserContext creation with/without sessions - Tests authentication status checking - Tests session expiration handling - Tests string representation - Tests API key hashing for anonymous users - Tests consistency of anonymous user IDs ### test_multi_user_session.py - Tests MultiUserSessionManager initialization - Tests session manager creation per API key - Tests session manager reuse for same API key - Tests isolation between different users - Tests auth status reporting - Tests context creation and retrieval ### test_request_context.py - Tests context variable get/set operations - Tests require_user_context() error handling - Tests context isolation between requests - Tests context updates and clearing - Tests None handling ## Code Quality All changes pass: - ✅ Python syntax checks (py_compile) - ✅ Black formatting (line-length 100) - ✅ Test structure validation - ✅ Import resolution ## CI/CD Impact These fixes should resolve: - ❌ Test execution failures (permission errors) - ❌ Black formatting check failures - ❌ Runtime errors when starting server with auth enabled Tests can now run in CI environment without requiring: - Root permissions - /app directory access - Pre-created cache directories # Pull Request ## Description  ## Type of Change  - [ ] Bug fix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to not work as expected) - [ ] Documentation update - [ ] Code refactoring - [ ] Performance improvement - [ ] Test improvement ## Related Issues  Fixes # ## Changes Made  - - - ## Testing Performed  - [ ] Unit tests added/updated - [ ] Integration tests added/updated - [ ] Manual testing performed - [ ] All existing tests pass ### Test Details  ```bash # Example test commands pytest tests/ ``` ## Screenshots (if applicable)  ## Checklist  - [ ] My code follows the project's style guidelines - [ ] I have performed a self-review of my code - [ ] I have commented my code, particularly in hard-to-understand areas - [ ] I have made corresponding changes to the documentation - [ ] My changes generate no new warnings - [ ] I have added tests that prove my fix is effective or that my feature works - [ ] New and existing unit tests pass locally with my changes - [ ] Any dependent changes have been merged and published - [ ] I have checked my code and corrected any misspellings ## Additional Context  ## Breaking Changes  ## Performance Impact  --- **By submitting this pull request, I confirm that my contribution is made under the terms of the MIT License.**

This commit fixes three critical issues identified in CI/CD and adds comprehensive test coverage for the new multi-user functionality.

Fixes

1. FastMCP Middleware Registration Error

Problem: AttributeError: 'FastMCP' object has no attribute 'app'

Solution: Implemented robust middleware registration that:

Tries multiple possible locations where FastMCP might store the app
Gracefully handles cases where app isn't immediately available
Wraps the run() method to defer middleware addition if needed
Attempts: _transport.app, sse.app, http_server.app, _app, _asgi_app
Falls back gracefully with warning if middleware can't be added

Files Changed:

src/geoguessr_mcp/main.py: Added smart middleware registration logic

2. Test Permission Errors

Problem: PermissionError: [Errno 13] Permission denied: '/app' Schema registry tried to create /app/data/schemas in CI without permission

Solution: Made schema cache directory creation fault-tolerant:

Catches PermissionError and OSError when creating cache directory
Falls back to temporary directory (tempfile.mkdtemp) if permission denied
Logs clear warning messages about fallback behavior
Tests can now run in restricted environments

src/geoguessr_mcp/monitoring/schema/schema_registry.py: Added fallback logic

3. Black Formatting Issues

Problem: 10 files needed reformatting

Solution: Ran black src/ --line-length 100 on all source files

Files Formatted:

src/geoguessr_mcp/config.py
src/geoguessr_mcp/api/dynamic_response.py
src/geoguessr_mcp/middleware/auth.py
src/geoguessr_mcp/main.py
src/geoguessr_mcp/auth/multi_user_session.py
src/geoguessr_mcp/tools/auth_tools.py
src/tests/integration/test_auth_flow.py
src/tests/unit/services/*.py (3 files)

New Tests

Added comprehensive test coverage for multi-user features:

test_user_context.py

Tests UserContext creation with/without sessions
Tests authentication status checking
Tests session expiration handling
Tests string representation
Tests API key hashing for anonymous users
Tests consistency of anonymous user IDs

test_multi_user_session.py

Tests MultiUserSessionManager initialization
Tests session manager creation per API key
Tests session manager reuse for same API key
Tests isolation between different users
Tests auth status reporting
Tests context creation and retrieval

test_request_context.py

Tests context variable get/set operations
Tests require_user_context() error handling
Tests context isolation between requests
Tests context updates and clearing
Tests None handling

Code Quality

All changes pass:

✅ Python syntax checks (py_compile)
✅ Black formatting (line-length 100)
✅ Test structure validation
✅ Import resolution

CI/CD Impact

These fixes should resolve:

❌ Test execution failures (permission errors)
❌ Black formatting check failures
❌ Runtime errors when starting server with auth enabled

Tests can now run in CI environment without requiring:

Root permissions
/app directory access
Pre-created cache directories
