|
|
- UserContext dataclass for per-user project tracking
|
|
- UserContextManager class with load/save operations
|
|
- Atomic persistence with backup rotation
|
|
- Multi-user isolation via separate context files
|
|
affects: [04-02, 04-03, orchestrator]

# Phase 4 Plan 01: UserContextManager Summary
|
|
|
|
**Per-user project context tracking with atomic persistence, enabling /gsd:use command functionality**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 7 min
|
|
- **Started:** 2026-03-11T10:43:13Z
|
|
- **Completed:** 2026-03-11T10:49:44Z
|
|
- **Tasks:** 3
|
|
- **Files modified:** 4
|
|
|
|
## Accomplishments
|
|
- UserContext dataclass with to_dict/from_dict methods for serialization
|
|
- UserContextManager with load/save, get_current_project, set_current_project, get_recent_projects methods
|
|
- Atomic writes with backup rotation (context.json -> context.json.bak)
|
|
- Multi-user isolation verified through 20 comprehensive tests
|
|
- Exports added to __init__.py for public API
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1-3: UserContextManager tests and implementation** - `fe7274a` (test)
|
|
- Note: Implementation was already done in commit 9bd29a2 as part of 04-02
|
|
- This commit adds the tests that complete the TDD cycle
|
|
|
|
**Plan metadata:** (pending)
|
|
|
|
## Files Created/Modified
|
|
- `src/gsd_openclaw/user_context.py` - UserContext dataclass and UserContextManager class (249 lines)
|
|
- `src/gsd_openclaw/__init__.py` - Added UserContext, UserContextManager exports
|
|
- `tests/conftest.py` - Added tmp_users_root and user_context_manager fixtures
|
|
- `tests/test_user_context.py` - Comprehensive test suite (20 tests in 4 test classes)
|
|
|
|
## Decisions Made
|
|
- User context stored per-user in ~/gsd-workspaces/.users/{user_id}/context.json
|
|
- Recent projects list limited to 5 entries (oldest removed when exceeded)
|
|
- Backup fallback on corrupted main file (matches state_manager.py pattern)
|
|
- Schema version "1.0" for future compatibility
|
|
|
|
## Deviations from Plan
|
|
|
|
### Auto-fixed Issues
|
|
|
|
**1. [Rule 1 - Bug] Fixed backup fallback test expectation**
|
|
- **Found during:** Task 2 (atomic write tests)
|
|
- **Issue:** Test expected backup to exist after first save, but backup only created on subsequent saves
|
|
- **Fix:** Updated test to save twice before corrupting main file, ensuring backup exists
|
|
- **Files modified:** tests/test_user_context.py
|
|
- **Verification:** All 20 tests pass
|
|
- **Committed in:** fe7274a (Task commit)
|
|
|
|
### Out-of-Order Execution
|
|
|
|
**Note:** The implementation (user_context.py) was already committed in 9bd29a2 as part of plan 04-02. This plan (04-01) was executed after 04-02, adding the test coverage that should have been written first in TDD fashion. The implementation matches the plan specification exactly.
|
|
|
|
---
|
|
|
|
**Total deviations:** 1 auto-fixed (test logic)
|
|
**Impact on plan:** Minor - test fixed to match correct backup rotation behavior
|
|
|
|
## Issues Encountered
|
|
- None beyond the test fix noted above
|
|
|
|
## User Setup Required
|
|
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- UserContextManager ready for use in orchestrator and /gsd:use command handling
|
|
- All tests passing, exports available via gsd_openclaw package
|
|
|
|
## Self-Check: PASSED
|
|
- user_context.py: FOUND
|
|
- test_user_context.py: FOUND
|
|
- SUMMARY.md: FOUND
|
|
- Commit fe7274a: FOUND
