Overview ¶
Package validation provides input validation utilities for security-critical operations.
This package contains validators for user-provided inputs that are used in database queries, file paths, or subprocess calls. Using these validators prevents injection attacks (SQL/Flux injection, command injection, path traversal).

Functions ¶
func SanitizeTicker ¶
SanitizeTicker normalizes and validates a ticker symbol. Returns the uppercase ticker if valid, or an error if invalid.
Use this when you need both validation and normalization:
safeTicker, err := validation.SanitizeTicker(userInput)
if err != nil {
return err
}
// safeTicker is uppercase and validated
func ValidateTicker ¶
ValidateTicker validates a stock ticker symbol to prevent Flux injection.
Valid tickers:
- 1-10 characters
- Uppercase letters A-Z
- Digits 0-9
- Dots (.) for class shares like BRK.A
- Hyphens (-) for class shares like BF-B
Returns an error if the ticker is invalid.
Example:
if err := validation.ValidateTicker(ticker); err != nil {
return nil, fmt.Errorf("invalid ticker: %w", err)
}
// Safe to use in Flux query
func ValidateTickers ¶
ValidateTickers validates multiple ticker symbols. Returns an error listing all invalid tickers if any fail validation.
