.golangci.yml (3)
29-30: Consider being more selective with govet checks.Using
enable-all: truefor govet might generate excessive noise. Consider explicitly enabling only the most relevant checks for your codebase to maintain a balance between strictness and practicality.govet: - enable-all: true + check-shadowing: true + fieldalignment: true + nilness: true + printf: true + structtag: true + tests: true
86-88: Consider a gradual linter adoption approach.Setting no limits (
0) on issues per linter and duplicate issues might be overwhelming during initial adoption. Consider starting with reasonable limits and gradually decreasing them as issues are fixed.issues: - max-issues-per-linter: 0 - max-same-issues: 0 + max-issues-per-linter: 20 + max-same-issues: 5
89-90: Consider adding path exclusions.To prevent linting of generated code, vendor directories, or test files (where appropriate), consider adding path exclusions:
run: timeout: 5m + skip-dirs: + - vendor + - generated + skip-files: + - ".*\\.generated\\.go$"nethttp/client_test.go (1)
58-67: Consider adding descriptive test case names.While the test structure is good, consider making the test cases more descriptive by adding a
namefield to the test struct. This would make test failures more informative.tests := []struct { + name string expectedTags map[string]interface{} url string opName string opts []ClientOption num int }{ - {url: "/ok", num: 3, opts: nil, opName: "HTTP Client"}, + {name: "basic_request", url: "/ok", num: 3, opts: nil, opName: "HTTP Client"},nethttp/client.go (1)
195-195: Document the rationale for ignoring the error.While the comment explains that checking the error causes test failures, it would be beneficial to document:
- Why the error can be safely ignored
- What types of errors could occur
- The impact of these errors on tracing functionality
This documentation would help future maintainers understand the trade-offs made here.

.golangci.yml (1)
89-90: LGTM!
The 5-minute timeout is a reasonable default that balances thoroughness with CI/CD pipeline efficiency.
nethttp/client_test.go (6)
Line range hint 19-37: Well-structured test helper with good practices!
The changes demonstrate good testing practices:
- Using t.Helper() for better error reporting
- Properly managing spans and cleanup
- Using modern context-aware request creation
71-124: Well-structured test execution with proper parallel test handling!
The changes demonstrate good practices:
- Proper variable capture in parallel tests
- Comprehensive span validation
- Clear error messages
129-130: LGTM! Consistent with parallel testing pattern.
161-164: Good addition of safety check for http.Hijacker!
The type assertion check improves error handling and provides a clearer error message.
280-290: Well-implemented helper function with proper error handling!
Good practices:
- Using t.Helper() for better error reporting
- Adding type safety checks
- Clear error messages
338-344: Good addition of peer.address tag validation!
The additional validation ensures proper handling of peer address information in spans.
nethttp/client.go (4)
36-37: LGTM! Field reordering improves readability.
The reordering of urlTagFunc and spanObserver fields in the clientOptions struct enhances code organization without impacting performance.
82-83: LGTM! Documentation improvement.
The comment correction enhances documentation clarity by fixing the spelling of "behavior".
104-121: LGTM! Well-structured example code.
The example effectively demonstrates proper usage of TraceRequest, including context handling, error management, and resource cleanup.
203-207: LGTM! Improved status code handling and method comparison.
Good improvements:
- The gosec linter suppression is properly justified as HTTP status codes cannot overflow uint16
- Using
http.MethodHeadconstant instead of string literal improves type safety and maintainability
nethttp/server_test.go (9)
4-4: LGTM: Good test performance improvements!
The addition of parallel test execution using t.Parallel() is a great improvement that will help reduce test execution time. The placement at the beginning of test functions is correct, and the context import is appropriately added to support the new request creation pattern.
Also applies to: 18-18, 37-37, 61-61, 87-87, 122-122, 195-195, 259-259, 315-315, 396-396, 437-437
28-31: LGTM: Improved test case structure
The restructuring of test case fields improves readability while maintaining the same test coverage and functionality.
Also applies to: 75-81
129-147: LGTM: Improved request creation and test cases
Good improvements:
- Using
http.MethodGetconstant instead of string literal "GET" - Comprehensive test cases covering different User-Agent scenarios
- Clear and well-structured test data
224-226: LGTM: Improved error handling in response writes
Good addition of error handling for response writes. The error messages are clear and will help with debugging test failures.
Also applies to: 229-231, 295-297, 406-408, 425-427
223-223: LGTM: Better usage of HTTP status code constants
Good replacement of magic numbers with http.Status* constants, improving code readability and maintainability.
Also applies to: 234-234, 240-240, 410-410, 429-429
265-270: LGTM: Improved request creation with context
Good improvement using http.NewRequestWithContext with proper error handling. This is a better practice for context management.
Also applies to: 321-326
399-399: LGTM: Better test case identification
Good addition of the name field to test cases, improving test output readability and maintenance.
Also applies to: 434-435
371-374: LGTM: Improved benchmark reliability
Good addition of error handling in benchmark response writes, consistent with other improvements in the test file.
120-122: Verify the necessity of linter suppression
The //nolint:paralleltest,tparallel directive is suppressing parallel test linting, but the test is actually running in parallel. This directive might be unnecessary.

��️ Refactor suggestion
Consider enabling context-related linters.
Given that this project involves HTTP operations and the PR objectives mention context handling improvements, these commented linters would be valuable:
contextcheck: Verifies proper context.Context usagenoctx: Finds HTTP requests without context.Contextwrapcheck: Ensures errors are wrapped with additional context

+ - contextcheck
- # - noctx
