WalkthroughThe changes refactor internal string and numeric parsing logic by removing dependencies on external packages and optimizing byte-level operations. Test coverage is significantly expanded for these core utility functions, with new test cases and dedicated tests targeting edge cases and recent optimizations. Changes

Tip For best results, initiate chat on the files or code changes. 🧩 Analysis chain@ReneWerner87, I'll help you extend the test cases to cover the new optimizations. Let me first examine the existing test structure and identify what coverage is missing. 🏁 Script executed: Length of output: 43507 🏁 Script executed: Length of output: 4471 Now I can see exactly what optimizations were made and where the test coverage gaps are. Based on the codecov report and my analysis, I'll create comprehensive test cases to cover all the new optimizations. flowchart TB

@ReneWerner87, I'll help you extend the test cases to cover all the new optimizations. Based on my analysis of the codecov report and the optimizations made, I've identified several areas where test coverage is missing: Missing Coverage Areas:
Planned Test Extensions:
The plan will create comprehensive test cases that not only achieve 100% coverage but also validate that the performance optimizations work correctly and maintain their performance benefits. Another agent will implement these changes when I include the `` tag. ⏳ Preparing changes... |

Pull Request Overview
This PR improves performance in utility functions by optimizing string case conversion, MIME parsing, and byte size calculations. Key changes include:
- Optimized ASCII case conversion in ToLower and ToUpper functions through early return and direct byte indexing.
- Improved MIME parsing in ParseVendorSpecificContentType by using IndexByte.
- Refactored ConvertToBytes to replace math.Pow with a precomputed sizeMultipliers table and use direct ASCII digit checks.

140-160: Suggest improving test case descriptions for clarity.Some test case descriptions could be more precise about the expected behavior, especially distinguishing between cases with and without '+' characters.
Consider updating descriptions to be more explicit:

🔇 Additional comments (11)
http_test.go (4)
106-108: Fix incorrect test expectation for semicolon before plus scenario.The test comment indicates "Semicolon before plus" but the input
"application/json; charset=utf-8+extra"has a semicolon before the plus sign. According to the function logic, when semicolon comes before plus, it should return everything before the semicolon, which is"application/json". However, the current expectation is correct.
82-101: LGTM! Well-designed test cases for vendor-specific content types.These test cases properly validate the function's core purpose of parsing vendor-specific content types with '+' notation. The expectations are correct and align with the function's logic.
110-115: LGTM! Good edge case coverage for minimal inputs.These edge cases properly test the function's behavior with empty strings and single special characters, ensuring robust handling of boundary conditions.
138-160:⚠️ Potential issueFix incorrect test case in the optimization test suite.
The test case on line 148-149 expects
"application/json"for input"application/json;charset=utf-8", but since there's no '+' character, the function should return the original string unchanged.- {"application/json;charset=utf-8", "application/json", "semicolon after content type"}, + {"application/json;charset=utf-8", "application/json;charset=utf-8", "semicolon after content type, no plus"},Likely an incorrect or invalid review comment.

❌ Incorrect review comment
Address undefined function errors preventing compilation.
While the test coverage is excellent, the static analysis and pipeline failures indicate that the
ToUpper,ToLower, and related functions are undefined. This suggests either missing implementations instrings.goor import issues.
🏁 Script executed:
#!/bin/bash # Check if the required functions are implemented in strings.go echo "=== Checking for function implementations ===" ast-grep --pattern 'func ToUpper($_) string { $$$ }' ast-grep --pattern 'func ToLower($_) string { $$$ }' ast-grep --pattern 'func IfToUpper($_) string { $$$ }' ast-grep --pattern 'func IfToLower($_) string { $$$ }' echo "=== Checking strings.go file existence ===" fd "strings.go" --type fLength of output: 2013

No missing implementations – tests will compile successfully.
The

138-160: Add t.Parallel calls to subtests for consistency.The table-driven test function provides excellent additional coverage for the IndexByte optimizations with clear test case descriptions. However, the subtests should call
t.Parallel()to be consistent with the parent test's parallel execution.Apply this diff to add the missing parallel calls:
for _, tc := range testCases { t.Run(tc.desc, func(t *testing.T) { + t.Parallel() require.Equal(t, tc.expected, ParseVendorSpecificContentType(tc.input), "input: %s", tc.input) }) }The test cases themselves are comprehensive and well-designed, covering edge cases like plus signs at different positions, missing slashes, and multiple special characters.

http_test.go (2)
78-80: LGTM! Test expectation correctly fixed.This change correctly addresses the past review comment. The test now properly expects
ParseVendorSpecificContentTypeto return the original string unchanged for regular content types without '+' characters, which aligns with the function's intended behavior.
82-115: Excellent comprehensive test coverage for IndexByte optimizations.These test cases provide thorough coverage of the IndexByte optimizations for '+', ';', and '/' characters in
ParseVendorSpecificContentType. The tests cover:
- Vendor-specific content types with plus signs (IndexByte for '+')
- Edge cases with multiple special characters
- Semicolon positioning relative to plus signs
- Empty and minimal inputs
- Invalid content types without slashes
The test organization with descriptive comments makes it clear which specific optimizations are being validated.
common_test.go (2)
134-134: Excellent fix of previous test expectation issues.The test expectations have been correctly updated based on the previous review feedback. The test now properly expects
ConvertToBytes("42X")to return 42 (the numeric part when unit is invalid) and"12a3"to return 0 (parsing failure due to invalid format).Also applies to: 161-161
76-168: Comprehensive test coverage validates performance optimizations.The expanded test coverage excellently validates the performance optimizations mentioned in the PR objectives:
- Tests for direct byte comparison digit detection (lines 85-90, 147-168)
- Tests for sizeMultipliers array usage across all supported units (k/K, m/M, g/G, t/T, p/P)
- Edge cases including invalid inputs, decimal numbers, and space handling
- Specific digit detection test function to validate the optimization replacing
unicode.IsDigitThis thorough testing ensures the optimizations maintain correctness while improving performance.
