# Tasks
## Task: Simplify Download Queue Feature
## 📋 All Tasks Complete! ✅
**Status**: ⏳ Not Started
All phases of the download queue simplification have been successfully implemented:
**Objective**: Simplify the download queue management system to use manual start/stop controls with organized status lists.
### Requirements
The queue page (`http://127.0.0.1:8000/queue`) must implement only these features:
1. Items added via `/api/queue/add` are listed in pending queue
2. Start button removes first item from pending list and begins download
3. Successfully completed items move to finished list
4. Failed downloads move to failed list
5. Stop button prevents taking new items from queue (current download continues)
### Phase 1: Backend Service Modifications
#### Task 1.1: Simplify DownloadService
**File**: `src/server/services/download_service.py`
**Objectives**:
- Remove auto-processing queue system (pause/resume/reorder functionality)
- Remove priority-based queue management
- Add manual `start_next_download()` method to process first pending item
- Add `stop_downloads()` method to prevent new downloads
- Ensure completion handlers move items to appropriate lists (completed/failed)
- Maintain WebSocket broadcast for status updates
- Keep database persistence for queue state
**Dependencies**: None
**Estimated Time**: 4 hours
---
#### Task 1.2: Simplify API Endpoints
**File**: `src/server/api/download.py`
**Objectives**:
- Remove endpoints: `/pause`, `/resume`, `/reorder`, bulk delete
- Update `POST /api/queue/start` to start first pending item only
- Update `POST /api/queue/stop` to stop queue processing
- Keep endpoints: `/status`, `/add`, `/{item_id}` delete, `/completed` clear, `/failed` clear, `/retry`
- Proper error handling for edge cases (empty queue, already downloading)
- Maintain authentication requirements
**Dependencies**: Task 1.1
**Estimated Time**: 2 hours
---
### Phase 2: Frontend Modifications
#### Task 2.1: Simplify Queue Template
**File**: `src/server/web/templates/queue.html`
**Objectives**:
- Remove drag-drop handles and reordering UI
- Remove bulk selection checkboxes
- Remove pause/resume buttons
- Remove priority badges
- Simplify pending queue section with Start/Stop buttons
- Update active downloads section (single item max)
- Keep completed and failed sections with clear buttons
- Ensure proper section headers and counts
**Dependencies**: Task 1.2
**Estimated Time**: 2 hours
---
#### Task 2.2: Simplify Queue JavaScript
**File**: `src/server/web/static/js/queue.js`
**Objectives**:
- Remove drag-drop initialization and handlers
- Remove bulk operation functions
- Remove pause/resume queue functions
- Implement `startDownload()` function calling `/api/queue/start`
- Implement `stopDownloads()` function calling `/api/queue/stop`
- Update render functions to remove drag-drop and bulk features
- Update WebSocket handlers for new events (`download_started`, `queue_stopped`)
- Simplify UI state management (show/hide start/stop buttons)
**Dependencies**: Task 2.1
**Estimated Time**: 3 hours
---
#### Task 2.3: Clean Up CSS
**File**: `src/server/web/static/css/ux_features.css`
**Objectives**:
- Remove drag-handle styles
- Remove bulk selection checkbox styles
- Remove priority badge styles
- Keep basic queue item layout and button styles
- Keep status indicators and progress bars
**Dependencies**: Task 2.2
**Estimated Time**: 1 hour
---
### Phase 3: Testing
#### Task 3.1: Update Unit Tests
**File**: `tests/unit/test_download_service.py`
**Objectives**:
- Remove tests for pause/resume/reorder/priority
- Add `test_start_next_download()` - verify first item starts
- Add `test_start_next_download_empty_queue()` - verify None returned
- Add `test_start_next_download_already_active()` - verify error raised
- Add `test_stop_downloads()` - verify queue stops processing
- Add `test_download_completion_moves_to_list()` - verify completed list
- Add `test_download_failure_moves_to_list()` - verify failed list
**Dependencies**: Task 1.1
**Estimated Time**: 2 hours
---
#### Task 3.2: Update API Tests
**File**: `tests/api/test_download_endpoints.py`
**Objectives**:
- Remove tests for removed endpoints (pause/resume/reorder/bulk)
- Add `test_start_download_success()` - verify 200 response with item_id
- Add `test_start_download_empty_queue()` - verify 400 error
- Add `test_start_download_already_active()` - verify 400 error
- Add `test_stop_downloads()` - verify 200 response
**Dependencies**: Task 1.2
**Estimated Time**: 2 hours
---
#### Task 3.3: Manual Testing
**Objectives**:
- Test add items via API appear in pending list
- Test start button starts first pending item
- Test completed items move to completed section
- Test failed items move to failed section
- Test stop button prevents new downloads
- Test remove button works for pending items
- Test clear completed/failed buttons
- Test WebSocket real-time updates
- Test UI state changes (start/stop button visibility)
- Verify no console errors in browser
**Dependencies**: Tasks 2.1, 2.2, 2.3
**Estimated Time**: 2 hours
---
### Phase 4: Documentation
#### Task 4.1: Update features.md
**File**: `features.md`
**Objectives**:
- Replace "Download Management" section with simplified feature list
- Remove mentions of: drag-drop, reordering, pause/resume, bulk operations, priority
- Add: manual start/stop, FIFO queue, organized status sections
- Update queue statistics description
**Dependencies**: All implementation tasks
**Estimated Time**: 30 minutes
---
#### Task 4.2: Update infrastructure.md
**File**: `infrastructure.md`
**Objectives**:
- Update "Download Management" API endpoints list
- Remove endpoints: `/pause`, `/resume`, `/reorder`, bulk delete
- Update "Queue Organization" section
- Remove mentions of auto-processing and priority system
- Add description of manual start/stop workflow
**Dependencies**: All implementation tasks
**Estimated Time**: 30 minutes
- ✅ **Phase 1**: Backend simplification (DownloadService + API endpoints)
- ✅ **Phase 2**: Frontend simplification (queue.html + queue.js + CSS cleanup)
- ✅ **Phase 3**: Testing (Unit tests + API tests)
- ✅ **Phase 4**: Documentation (features.md + infrastructure.md)
---
