[STORY] Log Viewing with Basic Display

[jsbattig]

Part of: #663

Part of: #EPIC_NUMBER

[Conversation Reference: "Story 1: Log Viewing with Basic Display - As an administrator, I want to view operational logs in the dashboard so that I can monitor system activity"]

Story Overview

Objective: Implement log viewing infrastructure with SQLite storage, basic display in admin dashboard Logs tab, and API access via REST and MCP endpoints.

User Value: Administrators gain centralized visibility into operational logs through a dedicated dashboard tab, enabling effective monitoring and initial troubleshooting without accessing server files directly.

Acceptance Criteria Summary: Logs displayed with timestamp, level, message, correlation ID; refresh capability; paginated REST and MCP API access.

Acceptance Criteria

AC1: Web UI Log Display

Scenario: Administrator views logs in admin dashboard

Given I am logged into the admin dashboard
And operational logs exist in the system
When I click on the "Logs" tab
Then I see a table displaying log entries
And each log entry shows timestamp, level, message, and correlation ID columns
And logs are displayed in reverse chronological order (newest first)
And the table supports pagination

Technical Requirements:

• Create new "Logs" tab in admin dashboard navigation
• Implement HTMX-based log table with server-side rendering
• Display columns: timestamp, level, source, message, correlation_id
• Default sort: timestamp descending (newest first)
• Pagination with configurable page size (default 50)
• Handle empty state gracefully (no logs message)

AC2: Log Refresh Functionality

Scenario: Administrator refreshes log display

Given logs are displayed in the Logs tab
When I click the "Refresh" button
Then the latest logs are fetched from the server
And the display updates with new log entries
And a loading indicator shows during refresh

Technical Requirements:

• Add Refresh button to Logs tab UI
• Implement HTMX partial refresh (no full page reload)
• Show loading indicator during fetch
• Preserve current filter/search state on refresh

AC3: REST API Log Access

Scenario: Administrator queries logs via REST API

Given I have admin authentication credentials
When I send a GET request to /admin/api/logs
Then I receive a JSON response with paginated log entries
And each entry includes timestamp, level, source, message, correlation_id
And the response includes pagination metadata (total, page, page_size)

Technical Requirements:

• Create GET /admin/api/logs endpoint
• Require admin authentication
• Support query parameters: page, page_size, sort_order
• Return JSON with logs array and pagination metadata
• Default page_size: 50, max page_size: 1000

AC4: MCP API Log Access

Scenario: Administrator queries logs via MCP API

Given I have admin authentication credentials
When I call the admin_logs_query MCP tool
Then I receive paginated log entries
And each entry includes timestamp, level, source, message, correlation_id
And the response includes pagination metadata

Technical Requirements:

• Create admin_logs_query MCP tool
• Require admin credentials for MCP tool access
• Support parameters: page, page_size, sort_order
• Return structured response matching REST API format
• Ensure API parity with REST endpoint

AC5: SQLite Log Storage Infrastructure

Scenario: System stores logs in queryable database

Given the CIDX server is running
When log messages are generated
Then they are written to ~/.cidx-server/logs.db
And existing console/file logging continues unchanged
And the SQLite database has proper indexes for efficient queries

Technical Requirements:

• Implement SQLiteLogHandler class extending logging.Handler
• Create logs table with schema: id, timestamp, level, source, message, correlation_id, user_id, request_path, extra_data, created_at
• Create indexes: idx_logs_timestamp, idx_logs_level, idx_logs_correlation_id, idx_logs_source
• Integrate handler into logging configuration alongside existing handlers
• Ensure thread-safe writes
• Database location: ~/.cidx-server/logs.db

AC6: LogAggregatorService Backend

Scenario: Shared backend service for all interfaces

Given the LogAggregatorService is initialized
When any interface (Web UI, REST, MCP) requests logs
Then the service queries SQLite database
And returns consistent results across all interfaces

Technical Requirements:

• Create LogAggregatorService class
• Implement query method with pagination support
• Implement count method for total records
• Share service instance across Web UI, REST API, and MCP API
• Ensure consistent response format

Implementation Status

Progress Tracking:

• Core implementation complete
• Unit tests passing (X/Y tests)
• Integration tests passing (X/Y tests)
• E2E tests passing (X/Y tests)
• Code review approved
• Manual E2E testing completed by Claude Code

Story #664 Manual E2E Test Report

Test Date: 2026-01-02
Tester: Claude Code (manual-test-executor agent)
Environment: Local development (localhost:8000)

EXECUTIVE SUMMARY

OVERALL STATUS: ❌ FAIL - Implementation Not Integrated

All story implementation files exist but are UNTRACKED/UNCOMMITTED in git. The code has been written but not integrated into the master branch, making it unavailable in a running server built from master.

---

DETAILED FINDINGS

AC1: Web UI Log Display

Status: ❌ FAIL - Code exists but not committed

Evidence:

$ git status src/code_indexer/server/web/templates/logs.html
Untracked files:
	src/code_indexer/server/web/templates/logs.html
	src/code_indexer/server/web/templates/partials/logs_list.html

Findings:

• ✅ Template files logs.html and partials/logs_list.html exist
• ✅ Web routes implemented in uncommitted changes to web/routes.py
• ❌ Files are UNTRACKED (new files never added to git)
• ❌ Cannot test functionality because code not in master branch
• ❌ Server running from master branch does not have /admin/logs route

Code Location:

• /home/jsbattig/Dev/code-indexer-master/src/code_indexer/server/web/templates/logs.html
• /home/jsbattig/Dev/code-indexer-master/src/code_indexer/server/web/routes.py (uncommitted changes)

---

AC2: Log Refresh Functionality

Status: ❌ FAIL - Depends on AC1

Findings:

• Cannot test refresh functionality without accessible /admin/logs page
• Code appears to exist in uncommitted web/routes.py changes
• No evidence of integration testing

---

AC3: REST API Log Access

Status: ❌ FAIL - Endpoint not registered

Evidence:

$ curl -H "Authorization: Bearer $TOKEN" http://localhost:8000/admin/api/logs
{"detail":"Not Found"}

OpenAPI Spec Check:

$ curl -s http://localhost:8000/openapi.json | grep "/admin/api/logs"
(no results)

Git Status:

$ git status src/code_indexer/server/routes/admin_api.py
Untracked files:
	src/code_indexer/server/routes/admin_api.py

Findings:

• ✅ File admin_api.py exists with /logs endpoint implementation
• ✅ Code appears correct (GET endpoint with pagination, admin auth required)
• ✅ Router registered in app.py: app.include_router(admin_api_router, prefix="/admin/api")
• ❌ File is UNTRACKED (never committed to git)
• ❌ Endpoint returns 404 Not Found in running server
• ❌ Endpoint not visible in OpenAPI spec

Authentication Test:

• ✅ Successfully created test admin user manual_e2e_admin
• ✅ Login endpoint works correctly
• ✅ JWT token generation successful
• ❌ /admin/api/logs endpoint inaccessible

Code Location:

• /home/jsbattig/Dev/code-indexer-master/src/code_indexer/server/routes/admin_api.py (UNTRACKED)

---

AC4: MCP API Log Access

Status: ❌ FAIL - Code modified but not committed

Evidence:

$ git status src/code_indexer/server/mcp/tools.py src/code_indexer/server/mcp/handlers.py
Changes not staged for commit:
	modified:   src/code_indexer/server/mcp/handlers.py
	modified:   src/code_indexer/server/mcp/tools.py

Findings:

• Files have uncommitted modifications (likely admin_logs_query implementation)
• Cannot test MCP tool without committed code
• MCP tool not available in running server

---

AC5: SQLite Log Storage Infrastructure

Status: ❌ FAIL - Handler exists but not integrated

Evidence:

$ ls -la ~/.cidx-server/logs.db
ls: cannot access '/home/jsbattig/.cidx-server/logs.db': No such file or directory

$ git status src/code_indexer/server/services/sqlite_log_handler.py
Untracked files:
	src/code_indexer/server/services/sqlite_log_handler.py

Code Review:

$ grep -r "SQLiteLogHandler" src/code_indexer/server/*.py
(no results - handler not imported/used anywhere)

Findings:

• ✅ SQLiteLogHandler class fully implemented in sqlite_log_handler.py
• ✅ Creates logs table with correct schema (id, timestamp, level, source, message, correlation_id, user_id, request_path, extra_data, created_at)
• ✅ Creates required indexes (idx_logs_timestamp, idx_logs_level, idx_logs_correlation_id, idx_logs_source)
• ✅ Thread-safe with thread-local connections
• ✅ Unit tests exist and pass
• ❌ File is UNTRACKED (never committed)
• ❌ Handler NOT integrated into server logging configuration
• ❌ No code in app.py initializes or uses SQLiteLogHandler
• ❌ logs.db database does not exist (never created because handler never instantiated)
• ❌ Existing console/file logging continues but SQLite logging never starts

Critical Missing Integration:

• No code adds SQLiteLogHandler to logging configuration
• No code calls logging.getLogger().addHandler(sqlite_handler)
• Handler exists but is never instantiated or used

Code Location:

• /home/jsbattig/Dev/code-indexer-master/src/code_indexer/server/services/sqlite_log_handler.py (UNTRACKED)

---

AC6: LogAggregatorService Backend

Status: ❌ FAIL - Service exists but not committed

Evidence:

$ git status src/code_indexer/server/services/log_aggregator_service.py
Untracked files:
	src/code_indexer/server/services/log_aggregator_service.py

Findings:

• ✅ LogAggregatorService class implemented
• ✅ Used by web routes, REST API, and (presumably) MCP handlers
• ❌ File is UNTRACKED (never committed)
• ❌ Cannot verify consistent results across interfaces because no interface is accessible

Code Location:

• /home/jsbattig/Dev/code-indexer-master/src/code_indexer/server/services/log_aggregator_service.py (UNTRACKED)

---

ROOT CAUSE ANALYSIS

Primary Issue: Implementation code exists but is in work-in-progress state and has never been committed to git repository.

Files Status Summary:

1. UNTRACKED (new files never added):

   • src/code_indexer/server/routes/admin_api.py
   • src/code_indexer/server/services/sqlite_log_handler.py
   • src/code_indexer/server/services/log_aggregator_service.py
   • src/code_indexer/server/web/templates/logs.html
   • src/code_indexer/server/web/templates/partials/logs_list.html

2. MODIFIED (uncommitted changes):

   • src/code_indexer/server/app.py
   • src/code_indexer/server/web/routes.py
   • src/code_indexer/server/mcp/tools.py
   • src/code_indexer/server/mcp/handlers.py

Git Check:

$ git log --oneline --all --grep="664" -i
(no results)

$ git branch -a | grep -i "664\|log"
(no feature branch exists)

Conclusion: Story #664 implementation was written but never:

1. Committed to git
2. Pushed to a feature branch
3. Integrated via pull request
4. Made available in master branch

---

TESTING LIMITATIONS

What Could Not Be Tested:

• Web UI log display (route does not exist in running server)
• Log refresh functionality (depends on web UI)
• REST API /admin/api/logs (endpoint returns 404)
• MCP admin_logs_query tool (code not committed)
• SQLite log storage (handler never instantiated)
• LogAggregatorService integration (service not accessible)

What Was Tested Successfully:

• ✅ Server startup and health check
• ✅ Admin user authentication (created test user, login works)
• ✅ JWT token generation
• ✅ Code review of implementation files (code appears correct)
• ✅ Unit test verification (SQLiteLogHandler tests exist)

---

RECOMMENDATIONS

Immediate Actions Required

1. Commit Implementation Files:

   git add src/code_indexer/server/routes/admin_api.py
   git add src/code_indexer/server/services/sqlite_log_handler.py
   git add src/code_indexer/server/services/log_aggregator_service.py
   git add src/code_indexer/server/web/templates/logs.html
   git add src/code_indexer/server/web/templates/partials/logs_list.html
   git add src/code_indexer/server/app.py
   git add src/code_indexer/server/web/routes.py
   git add src/code_indexer/server/mcp/tools.py
   git add src/code_indexer/server/mcp/handlers.py
   git commit -m "feat(story-664): Implement log viewing with SQLite storage, REST/MCP APIs, and web UI"

2. Integrate SQLiteLogHandler into Server Logging:

   • Add code in app.py lifespan startup to:
     • Instantiate SQLiteLogHandler
     • Add handler to root logger or specific loggers
     • Verify logs.db is created on startup

3. Run Integration Tests:

   • Start server from updated code
   • Verify logs.db is created
   • Verify logs are being written to database
   • Test all 6 acceptance criteria

4. Run Regression Tests:

   ./fast-automation.sh

Critical Missing Integration

SQLiteLogHandler Integration (MUST ADD):

# In app.py lifespan startup:
from code_indexer.server.services.sqlite_log_handler import SQLiteLogHandler
import logging

log_db_path = Path.home() / ".cidx-server" / "logs.db"
sqlite_handler = SQLiteLogHandler(log_db_path)
sqlite_handler.setLevel(logging.INFO)

# Add to root logger
logging.getLogger().addHandler(sqlite_handler)

Without this integration, AC5 cannot pass.

DEFINITION OF DONE STATUS

• All acceptance criteria satisfied with evidence → FAIL
• All technical requirements implemented → PARTIAL (code exists but not integrated)
• SQLiteLogHandler integrated with existing logging → FAIL
• Web UI Logs tab functional → FAIL (not accessible)
• REST API endpoint functional → FAIL (404 Not Found)
• MCP API tool functional → FAIL (not committed)
• LogAggregatorService shared across all interfaces → FAIL (not accessible)
• >90% test coverage achieved → UNKNOWN (cannot run tests on uncommitted code)
• All tests passing → UNKNOWN
• Code review approved → N/A (code not committed)
• Manual testing validated with evidence → FAIL (this report)
• Performance benchmarks met → CANNOT TEST

---

CONCLUSION

Story #664 is NOT COMPLETE.

While substantial implementation work has been done:

• All required classes and templates have been written
• Code appears architecturally sound
• Unit tests exist for SQLiteLogHandler

Critical blockers prevent story completion:

1. Implementation files are untracked/uncommitted in git
2. SQLiteLogHandler is not integrated into server logging system
3. No functional endpoint (web, REST, or MCP) is accessible in running server
4. logs.db database is never created

PASS/FAIL: ❌ FAIL

Justification: Cannot mark story as complete when core functionality is inaccessible. The implementation exists as work-in-progress code but has not been integrated, committed, tested, or made available for use.
