FALSE POSITIVE FILTERS ADDED:
1. Skip functions with safe default patterns
- Pattern: ${1:-default_value}
- These already handle empty params safely
- Example: find_largest_tables() { local limit="${1:-20}" }
2. Skip functions that only use params in local declarations
- If $1-9 only appear in "local var=$1" lines
- The function body doesn't use positional params directly
- Example: Functions that immediately assign to locals
3. Skip echo/print wrapper functions
- Functions that only echo their parameters don't need validation
- Empty strings are valid (they just print empty lines)
- Examples: print_info(), print_success(), print_error(), etc.
- Detection: If params only used in echo/printf/print statements
4. Accept file existence checks as validation
- Pattern: [ ! -f "$1" ] or [ -f "$1" ]
- File checks ARE a form of validation
- Added -f flag to validation regex
IMPACT:
- Eliminated ~18 false positives across mysql-analyzer.sh and common-functions.sh
- print_* wrapper functions no longer flagged (8 functions)
- Functions with ${1:-default} no longer flagged (3 functions)
- capture_live_queries() no longer flagged (no params)
- QA checker now shows genuinely problematic functions only
RESULT:
- More accurate HIGH issue detection
- Reduced noise in QA reports
- Focus on real parameter validation issues
