# Phase 2 Features - Implementation Summary

## ✅ Features Implemented

### 1. Right-Click Context Menu for Job Abortion

**Feature:** Users can right-click on "in_progress" jobs to abort them.

**Implementation:**
- Added context menu that appears on right-click
- Only shows for jobs with status "in_progress"
- Clicking "Abort Job" marks the job as aborted (⚫ black icon)
- Context menu automatically hides when clicking elsewhere

**Files Modified:**
- `app/templates/dashboard/index.html` - Added context menu HTML and JavaScript
- `app/static/css/style.css` - Added context menu styling

**Usage:**
1. Right-click on any job with orange icon (in progress)
2. Select "Abort Job" from the context menu
3. Job status changes to aborted (black icon)

---

### 2. Git Branch Validation

**Feature:** Validates that the branch exists on remote before allowing job submission.

**Implementation:**
- When user enters branch name and clicks "Validate Branch"
- System executes SSH commands to remote server:
  1. `./TPF/gitea_repo_controller.sh clone` - Clones/updates repository
  2. `./TPF/gitea_repo_controller.sh checkout <branch_name>` - Checks out branch
- Parses output to detect success or failure
- Shows appropriate message to user

**Success Flow:**
```
User enters branch → Clicks "Validate Branch" → 
Loading indicator → SSH commands execute → 
Branch found → Green success message → 
"Next" button appears → User proceeds to scenario selection
```

**Failure Flow:**
```
User enters branch → Clicks "Validate Branch" → 
Loading indicator → SSH commands execute → 
Branch not found (fatal: error) → Red error message → 
"Branch not found on remote. Please push the branch first." → 
User cannot proceed
```

**Files Modified:**
- `app/routes/jobs.py` - Added branch validation logic with SSH commands
- `app/templates/jobs/submit.html` - Added AJAX validation and UI feedback
- `app/static/css/style.css` - Added validation message styling
- `Dockerfile` - Added sshpass package
- `docker-compose.yml` - Added SSH environment variables
- `.env.example` - Added SSH configuration template

**Configuration Required:**

Update these environment variables in `docker-compose.yml` or `.env`:
```env
SSH_PASSWORD=your_actual_password
SSH_HOST=asfserver
SSH_USER=asf
```

---

## 🔧 Technical Details

### SSH Command Execution

The system uses `subprocess` to execute SSH commands:

```python
# Clone repository
clone_cmd = f"sshpass -p '{ssh_password}' ssh -o StrictHostKeyChecking=no {ssh_user}@{ssh_host} './TPF/gitea_repo_controller.sh clone'"

# Checkout branch
checkout_cmd = f"sshpass -p '{ssh_password}' ssh -o StrictHostKeyChecking=no {ssh_user}@{ssh_host} './TPF/gitea_repo_controller.sh checkout {branch_name}'"
```

### Error Detection

The system detects branch validation failures by checking for:
- "fatal:" in stdout or stderr
- Non-zero return code
- Timeout (60 seconds)

### Security Considerations

⚠️ **Important:** The SSH password is stored in environment variables. For production:
1. Use SSH keys instead of passwords
2. Store credentials in a secure vault (e.g., HashiCorp Vault)
3. Use encrypted environment variables
4. Implement proper access controls

---

## 📋 Deployment Steps

### 1. Update Configuration

Edit `docker-compose.yml`:
```yaml
environment:
  SSH_PASSWORD: your_actual_password  # Replace with real password
  SSH_HOST: asfserver                 # Your SSH host
  SSH_USER: asf                       # Your SSH user
```

### 2. Rebuild Container

```bash
docker-compose down
docker-compose up -d --build
```

### 3. Test Branch Validation

1. Go to Submit New Job
2. Enter a valid branch name
3. Click "Validate Branch"
4. Should see green success message
5. Try invalid branch - should see red error

### 4. Test Job Abortion

1. Create a job (it will be "in progress")
2. Right-click on the job
3. Select "Abort Job"
4. Job icon should turn black (⚫)

## 🎨 UI/UX Improvements

### Context Menu
- Clean, modern design
- Smooth hover effects
- Automatically positions near cursor
- Closes when clicking elsewhere

### Branch Validation
- Three states: Loading (yellow), Success (green), Error (red)
- Loading spinner animation
- Clear error messages
- Disabled "Next" button until validation succeeds
- Re-validation required if branch name changes

### Visual Feedback
- ⚫ Black icon for aborted jobs
- 🟠 Orange icon for in-progress jobs
- 🟢 Green icon for passed jobs
- 🔴 Red icon for failed jobs

## 🐛 Known Limitations

1. **SSH Password Security:** Currently stored in plain text environment variables
2. **No Retry Logic:** If SSH command fails, user must manually retry
3. **Timeout:** 60-second timeout for SSH commands
4. **No Progress Bar:** User doesn't see detailed progress during validation
5. **Single Server:** Only supports one SSH host

---

## 🚀 Future Enhancements

### Suggested Improvements:
1. **SSH Key Authentication:** Replace password with SSH keys
2. **Retry Logic:** Automatic retry on transient failures
3. **Progress Indicators:** Show detailed progress during validation
4. **Multiple Servers:** Support for multiple SSH hosts
5. **Caching:** Cache branch validation results
6. **Webhooks:** Real-time notifications when branch is pushed
7. **Batch Operations:** Abort multiple jobs at once
8. **Job History:** Show abort history and who aborted

## 📞 Support

If you encounter issues:

1. **Branch Validation Fails:**
   - Check SSH credentials in docker-compose.yml
   - Verify sshpass is installed: `docker exec testarena_web which sshpass`
   - Check SSH connectivity: `docker exec testarena_web ssh asf@asfserver`
   - Review logs: `docker-compose logs web`

2. **Context Menu Not Showing:**
   - Ensure job status is "in_progress"
   - Check browser console for JavaScript errors
   - Clear browser cache

3. **Abort Not Working:**
   - Check logs: `docker-compose logs web`
   - Verify job exists in database
   - Check user permissions
