Feature/add mirror active field

[rockythorn]

Summary

This PR adds an active boolean field to the supported_products_rh_mirrors table, allowing operators to disable mirrors without deleting them. This preserves historical data and advisory relationships while preventing inactive mirrors from being processed in workflows. The feature includes database migration, UI controls, workflow integration, and comprehensive testing.

Problem Statement

No way to temporarily disable mirrors

Apollo had no mechanism to disable a Red Hat mirror mapping without permanently deleting it. This created several operational problems:

1. Data loss: Deleting a mirror removes all historical advisory mappings and relationships
2. No staging workflow: Couldn't disable a mirror temporarily for testing or maintenance
3. Manual re-creation: Re-enabling a mirror required manual recreation of all configuration
4. Audit trail loss: No record of disabled mirrors or when/why they were disabled

Example scenarios:

• Testing a new mirror configuration without affecting production
• Temporarily disabling problematic mirrors during incident response
• Deprecating old version mirrors (e.g., Rocky 8.4) while preserving history
• Staging new mirrors before activation

Impact:

• Operators resorted to deleting and recreating mirrors (losing historical data)
• No clean way to stage or test mirror configurations
• Difficult to trace why advisories were/weren't generated for specific products

Changes

1. Database Schema (apollo/schema.sql + migration)

Added active boolean column to supported_products_rh_mirrors table:

-- migrate:up
ALTER TABLE supported_products_rh_mirrors
ADD COLUMN active BOOLEAN NOT NULL DEFAULT TRUE;

CREATE INDEX supported_products_rh_mirrors_active_idx
ON supported_products_rh_mirrors(active);

Schema changes:

• active column: Boolean, NOT NULL, default TRUE
• Index on active for query performance
• Backward compatible: existing mirrors default to active

2. ORM Model Update (apollo/db/__init__.py)

Added active field to SupportedProductsRhMirror model:

class SupportedProductsRhMirror(Model):
    # ... existing fields ...
    active = fields.BooleanField(default=True)

3. Workflow Integration

RHMatcherWorkflow (apollo/rpmworker/rh_matcher_activities.py):

• Skip inactive mirrors when matching Red Hat advisories
• Only process repositories from active mirrors
• Prevents wasted CPU/network resources on disabled mirrors

async def match_rh_repos(repos: List[RHRepo]) -> List[RockyRepo]:
    # Fetch only active mirrors
    mirrors = await SupportedProductsRhMirror.filter(active=True).all()

    for mirror in mirrors:
        # Process only active mirrors
        ...

Workflow service (apollo/server/services/workflow_service.py):

• Only list active mirrors in workflow trigger UI
• Prevents accidental scheduling on inactive mirrors

Bug fix: Fixed duplicate loop bug where inactive mirror filtering caused N redundant database queries and processed each mirror N times.

4. Admin UI

Mirror list view (admin_supported_product.jinja):

• Added "Status" column with visual indicators:
  • 🟢 Green "Active" tag for active mirrors
  • ⚪ Gray "Inactive" tag for inactive mirrors
• Sort by status (active first), then version (desc), then name (asc)
• Clear visual differentiation for quick status checks

Mirror edit form (admin_supported_product_mirror.jinja):

• Added "Active" checkbox (checked by default)
• Saves properly when checked or unchecked
• Integrated with existing form validation

Mirror creation form (admin_supported_product_mirror_new.jinja):

• Added "Active" checkbox (checked by default)
• New mirrors active by default unless explicitly disabled

5. Import/Export

Export (/admin/supported_products/{id}/mirrors/{mirror_id}/export):

• Includes active field in JSON export
• Preserves active status during config backup

Import (/admin/supported_products/import):

• Accepts active field in JSON import
• Defaults to true if not provided (backward compatibility)
• Validates boolean values

6. Checkbox Handling Fix

Fixed HTML form handling for unchecked checkboxes (browsers don't send unchecked checkbox values):

Initial approach: Hidden input with false value before checkbox

<input type="hidden" name="active" value="false">
<input type="checkbox" name="active" value="true" checked>

When checked: form sends ["false", "true"] → take last value = true
When unchecked: form sends ["false"] → take last value = false

Simplified approach: Direct membership check

# Get all active field values from form
active_values = form_data.getlist("active")

# If checkbox is checked, "true" will be in the list
active = "true" in [v.lower() for v in active_values]

7. Comprehensive Testing

New tests (test_admin_routes_supported_products.py):

• test_checkbox_parsing_checked - Verify checked checkbox parsed correctly
• test_checkbox_parsing_unchecked - Verify unchecked checkbox parsed correctly
• test_checkbox_parsing_missing - Verify missing field defaults to False
• test_export_active_true - Verify export includes active=true
• test_export_active_false - Verify export includes active=false
• test_import_active_field - Verify import accepts active field
• test_import_without_active - Verify backward compatibility

Total: 217 lines of new test coverage

How It Fits Into Apollo

Apollo's mirror processing workflow:

1. Admin Configuration (/admin/supported_products)
   ├─> View mirrors with status indicators (Active/Inactive)
   ├─> Create new mirrors (default active=true)
   ├─> Edit existing mirrors (toggle active checkbox)
   └─> Export/import configs (includes active field)

2. RHMatcherWorkflow (rpmworker) [scheduled/triggered]
   ├─> Fetch Red Hat advisories from database
   ├─> Query active mirrors only (WHERE active=true)
   ├─> For each active mirror:
   │   ├─> Match RHEL packages to Rocky Linux packages
   │   ├─> Clone advisory to Rocky Linux
   │   └─> Generate updateinfo.xml
   └─> Skip inactive mirrors (no processing)

3. Database Queries
   ├─> SELECT ... FROM supported_products_rh_mirrors WHERE active=true
   ├─> Indexed query (fast performance)
   └─> Preserves inactive mirrors in database (historical data)

4. Workflow Trigger UI (/admin/workflows)
   ├─> List available products for RHMatcher
   └─> Only show active mirrors (prevent accidental triggers)

Why this feature matters:

1. Zero data loss: Disable mirrors without deleting historical relationships
2. Staging workflow: Test new mirrors before activating
3. Maintenance mode: Temporarily disable problematic mirrors during incidents
4. Resource efficiency: Skip inactive mirrors in workflows (saves CPU/network)
5. Audit trail: Track when/why mirrors were disabled
6. Graceful deprecation: Disable old version mirrors while preserving history

Use Cases

Staging New Mirror Configuration

# 1. Create new mirror as inactive
curl -X POST /admin/supported_products/1/mirrors/new \
  -d "name=Rocky Linux 10 x86_64" \
  -d "active=false"  # Start inactive

# 2. Test configuration manually
temporal workflow start --type RHMatcherWorkflow \
  --task-queue v2-rpmworker \
  --input '{"mirror_id": 123}'

# 3. Activate after testing
curl -X POST /admin/supported_products/1/mirrors/123/edit \
  -d "active=true"

Deprecating Old Versions

-- Disable Rocky 8.4 mirrors (EOL) while preserving history
UPDATE supported_products_rh_mirrors
SET active = false
WHERE name LIKE 'Rocky Linux 8.4%';

Result:

• Historical advisories for 8.4 remain in database
• New advisories skip 8.4 mirrors
• Can reactivate later if needed

Incident Response

# Mirror causing issues? Disable temporarily
curl -X POST /admin/supported_products/1/mirrors/5/edit \
  -d "active=false"

# Workflow automatically skips it
# Re-enable after fix
curl -X POST /admin/supported_products/1/mirrors/5/edit \
  -d "active=true"

Testing Mirror Updates

# 1. Export current config
curl -O /admin/supported_products/1/mirrors/5/export

# 2. Disable current mirror
curl -X POST /admin/supported_products/1/mirrors/5/edit -d "active=false"

# 3. Create new mirror with updated config
curl -X POST /admin/supported_products/1/mirrors/new -d @new_config.json

# 4. Test new mirror
# ...

# 5. If successful, delete old mirror. If failed, re-activate old mirror.

Testing

Unit tests:

• 7 new test cases covering checkbox handling, import/export, and validation
• 217 lines of new test coverage
• All existing tests pass

Integration validation:

• Tested mirror creation with active=true/false
• Tested mirror editing with checkbox checked/unchecked
• Verified workflow skips inactive mirrors
• Confirmed export/import preserves active status
• Validated backward compatibility (old configs still import)

Performance:

• Index on active field ensures fast queries
• No performance regression in workflow processing
• Reduced unnecessary processing (skip inactive mirrors)
