The validation script reveals the scope of remaining work while confirming that the infrastructure is ready for systematic migration. Phase 2 should focus on high-impact files, starting with the 4 mixed-pattern components that pose immediate security risks. + +The foundation is solid, tools are in place, and the path forward is clear. \ No newline at end of file diff --git a/scripts/validate-migration.sh b/scripts/validate-migration.sh new file mode 100755 index 00000000..cf62b93e --- /dev/null +++ b/scripts/validate-migration.sh @@ -0,0 +1,249 @@ +#!/bin/bash + +# TimeSafari PlatformServiceMixin Migration Validation Script +# Author: Matthew Raymer +# +# This script validates the migration status from legacy patterns to PlatformServiceMixin +# and provides detailed reporting on migration progress. + +set -e + +# Colors for output +RED='\033[0;31m' +GREEN='\033[0;32m' +YELLOW='\033[1;33m' +BLUE='\033[0;34m' +NC='\033[0m' # No Color + +echo -e "${BLUE}🔍 TimeSafari PlatformServiceMixin Migration Validation${NC}" +echo "==================================================" + +# Initialize counters +total_issues=0 +legacy_db_imports=0 +legacy_log_imports=0 +direct_platform_usage=0 +mixin_usage=0 + +# Function to log with timestamp +log_with_timestamp() { + echo -e "[$(date '+%Y-%m-%d %H:%M:%S')] $1" +} + +# Function to check for legacy patterns +check_legacy_patterns() { + echo -e "\n${YELLOW}📋 Checking for legacy patterns...${NC}" + + # Check for legacy databaseUtil imports + echo -n " Checking databaseUtil imports...
