Critical bug in unsupported type handling logic.

The refactored function has excellent error handling for supported types, but there's a logical inconsistency for unsupported types:

1. Line 853: For unsupported types, the function returns (zero_value, nil) - no error is returned
2. Consumer functions (in ctx.go): Only use default values when err != nil AND len(defaultValue) > 0
3. Issue: For unsupported types, since no error is returned, the zero value will always be returned even when a default value is provided

This contradicts the documented behavior in the comments added to ctx.go (lines 647-648, 1111-1112) which state that unsupported types should return the default value if provided.

Fix for unsupported type handling:

	default:
-		return v, nil
+		return v, errors.New("unsupported generic type")

Address test coverage gaps:

The static analysis indicates several error handling paths lack test coverage. Consider adding tests for:

• Integer overflow scenarios (lines 767-768, 791-792, etc.)
• Invalid boolean values (lines 839-840)
• Unsupported types (line 853)

Would you like me to generate comprehensive test cases to improve coverage of these error handling paths?

No issue: unsupported branch is unreachable under the GenericType constraint

The default case in genericParseType only ever applies if you instantiate the function with a type outside the GenericType union. But Go’s type‐list constraints (GenericType = int|int8|…|float64|bool|string|[]byte) prevent you from calling genericParseType with any other type at compile time. As a result:

• The default path (return v, nil) is never taken at runtime.
• Consumers correctly get a non-nil error only when parsing fails on supported types, so the default-value logic in ctx.go works as intended.

No change or additional test is needed for “unsupported types.” Please disregard the suggested errors.New("unsupported generic type") patch.

ctx.go (1)

647-654: Error handling pattern is correct, but comment doesn't match implementation.

The error handling logic correctly returns the default value when parsing fails AND a default is provided. However, the comment states that unsupported types return the default value, but the current implementation in genericParseType doesn't return an error for unsupported types, so the default won't be used.

This inconsistency should be resolved by fixing the unsupported type handling in helpers.go as noted in the previous comment.

ctx_test.go (6)

31-31: Good use of unsafe package for determining native type sizes.

The addition of the unsafe package is appropriate here as it's used to dynamically determine the bit sizes of native int and uint types in the tests, making them portable across different architectures.

---

5255-5380: Excellent refactoring of integer parsing tests!

The consolidated test structure with systematic coverage of all integer types and their boundaries is a significant improvement. The use of subtests and proper error checking for out-of-range values enhances test reliability.

---

5383-5493: Well-structured unsigned integer parsing tests.

The tests properly cover all unsigned integer types with appropriate boundary testing and error handling for overflow conditions.

---

5496-5538: Proper implementation of float parsing tests with epsilon comparison.

Good use of require.InEpsilon for floating-point comparisons, which correctly handles precision issues.

---

5541-5580: Correct implementation of byte parsing tests with explicit error handling.

The tests properly validate the new error behavior where empty strings return errParsedEmptyBytes, aligning with the PR's objective of explicit error handling.

---

5639-5803: Excellent benchmark coverage with helper functions.

The benchmarks are comprehensive and well-structured. The use of helper functions benchGenericParseTypeInt and benchGenericParseTypeUInt effectively reduces code duplication while maintaining thorough coverage of all type boundaries.

helpers.go (2)

756-760: LGTM! Well-defined error variables for explicit error handling.

The error variables provide clear, descriptive messages for different parsing failure scenarios, which aligns well with the refactoring goal of making error handling more explicit.

---

766-855: Solid implementation with room for improved test coverage.

The type-specific parsing logic is well-implemented:

• Correct use of strconv functions with appropriate bit sizes
• Consistent error wrapping with descriptive messages
• Proper type assertions for generic return values

However, static analysis indicates several error handling paths lack test coverage. Consider adding tests for these scenarios to ensure robust error handling.

Would you like me to help generate comprehensive test cases for the error handling paths to improve coverage?

helpers_test.go (4)

8-9: LGTM! Required imports for new tests.

The added imports are necessary for the new generic parsing tests - math for type constants, strconv for number formatting, and unsafe for sizeof operations.

Also applies to: 13-13

---

673-1315: Excellent test coverage for generic parsing!

The test implementation is comprehensive and well-structured:

• Covers all supported types (integers, floats, bytes, strings, booleans)
• Tests boundary values and error cases
• Includes both unit tests and benchmarks
• Uses generics effectively to reduce code duplication

The test design follows good practices with clear separation between test data and test logic.

No missing epsilon definition—tests share the same package

The epsilon constant is defined in ctx_test.go (const epsilon = 0.001) and, since both ctx_test.go and helpers_test.go declare package fiber, the constant is in scope. There’s no compilation error.

ctx_test.go (6)

2496-2496: LGTM! Good test coverage for default value behavior.

This addition properly tests that the generic Params function correctly returns a default value when an optional parameter is not provided, which aligns with the refactoring to improve error handling mentioned in the PR objectives.

---

5254-5280: LGTM! Well-structured test for Drop() functionality.

The test correctly verifies that:

• Drop() prevents any response from being sent (verified by ErrTestGotEmptyResponse)
• Normal handlers without Drop() still work as expected
• Proper error checking and assertions are used

---

5283-5304: LGTM! Good test coverage for Drop() with middleware interaction.

This test properly verifies that Drop() works correctly even when middleware attempts to set headers after c.Next(), ensuring the connection is still dropped as expected.

---

5307-5322: LGTM! Proper test for End() functionality.

The test correctly verifies that End() allows content to be sent before ending the response, which is the expected behavior for this lifecycle control method.

---

5340-5360: LGTM! Good test for complex middleware interaction.

This test properly verifies the interaction between End() and middleware that calls Drop() after c.Next(), ensuring that End() takes precedence and the response is still sent.

---

5363-5381: LGTM! Comprehensive test for Drop() and End() interaction.

This test correctly verifies that when Drop() is called first, subsequent End() calls don't change the behavior - the connection remains dropped. The test structure with middleware is well-designed.
