This commit adds two new string filter types to match "contains" and "does not contain": - starts_with: matches strings that start with the specified prefix - not_starts_with: matches strings that do not start with the specified prefix Changes: - proto: Added starts_with and not_starts_with fields to StringCondition message - backend: Updated matchesStringCondition() to handle new filter types using bytes.HasPrefix - frontend UI: Added "Starts With" and "Not Starts With" options to filter dropdown - frontend types: Updated ProfileFilter interface and createStringCondition() for new match types - tests: Added 4 comprehensive tests covering stack and frame filters with both new filter types The implementation follows the same pattern as existing contains/not_contains filters, with case-insensitive matching and proper null handling.
The NotStartsWith filter was being treated as a positive condition, causing incorrect filter logic. Stack filters with negative conditions need ALL functions to not match (AND logic), while positive conditions need ANY function to match (OR logic). Fixed in 4 functions: - handleUnsymbolizedFunctionCondition - matchesFunctionNameInRange - matchesSystemNameInRange - matchesFilenameInRange This fixes the failing TestStackFilterFunctionNameNotStartsWith test.
NewRecordReader now returns (reader, error) instead of just reader. Updated all 4 test cases to handle the error return value.
