middleware/timeout/timeout.go (1)
Line range hint
11-28: Consider adding documentation about timeout behavior.While the implementation is solid, it would be helpful to add documentation comments explaining:
- The timeout behavior and its impact on request processing
- How custom timeout errors are handled
- Examples of common use cases
Example documentation:
+// New creates a timeout middleware that cancels the request processing if it takes +// longer than the specified duration. It returns fiber.ErrRequestTimeout when: +// - The context deadline is exceeded +// - Any of the specified custom errors (tErrs) occur +// +// Example: +// +// app.Use(timeout.New(handler, 5*time.Second)) +// +// // With custom timeout errors +// app.Use(timeout.New(handler, 5*time.Second, ErrSlowDB, ErrSlowAPI)) func New(h fiber.Handler, t time.Duration, tErrs ...error) fiber.Handler {middleware/expvar/expvar.go (1)
Line range hint
19-30: Consider adding security recommendations for debug endpoints.The
/debug/varsendpoint exposes runtime statistics which could be sensitive in production environments.Consider:
- Adding a configuration option to disable this middleware in production
- Documenting security best practices (e.g., IP restrictions, authentication) for protecting this endpoint
- Adding a warning log when this middleware is enabled in production
Would you like me to help draft the security documentation and implementation?
middleware/redirect/redirect.go (1)
33-36: Consider documenting query string security implicationsWhile the query string handling is implemented correctly, it might be worth adding a comment about potential security implications of preserving query parameters during redirects, especially for sensitive operations.
Consider adding a comment like:
+ // Preserve query string during redirect, ensure sensitive parameters are handled appropriately queryString := string(c.RequestCtx().QueryArgs().QueryString()) if queryString != "" { queryString = "?" + queryString }middleware/requestid/requestid_test.go (1)
54-84: LGTM! Well-structured table-driven tests.The test structure effectively covers both
fiber.Ctxandcontext.Contextscenarios, aligning well with the PR objective of adding context support.Consider updating to use
anyinstead ofinterface{}since the project uses Go 1.18+:type args struct { - inputFunc func(c fiber.Ctx) interface{} + inputFunc func(c fiber.Ctx) any }🧰 Tools

middleware/pprof/pprof.go (1)
51-71: Consider security implications of exposed pprof endpoints.Since pprof endpoints expose sensitive runtime information about your application, ensure that:
- These endpoints are properly secured in production
- Access is restricted to authorized personnel
- Consider implementing additional middleware for authentication/authorization when accessing these endpoints
You might want to wrap this middleware with security checks or disable it completely in production unless explicitly needed for debugging.
middleware/etag/etag.go (1)
95-95: LGTM! Consider documenting the API changeThe change maintains consistency with the new context handling approach.
Consider adding a note in the framework's upgrade guide about the migration from
Context()toRequestCtx()to help users update their code.docs/middleware/timeout.md (3)
11-11: Enhance context propagation documentationWhile the explanation is accurate, it would be helpful to add more details about how the timeout context is propagated through the request lifecycle and its implications for downstream operations.
Consider adding:
-As a `fiber.Handler` wrapper, it creates a context with `context.WithTimeout` which is then used with `c.Context()`. +As a `fiber.Handler` wrapper, it creates a context with `context.WithTimeout` which is then used with `c.Context()`. This timeout context is propagated to all downstream operations, allowing them to respect the timeout constraint and gracefully handle cancellation.
87-87: Consider improving error variable namingWhile the implementation is correct, consider using a more descriptive error variable name.
-var ErrFooTimeOut = errors.New("foo context canceled") +var ErrOperationTimeout = errors.New("operation context canceled")
119-119: Improve DB transaction error handlingWhile the context usage is correct, the DB transaction example could be improved with better error handling and transaction management.
Consider updating the example to include transaction rollback:
handler := func(ctx fiber.Ctx) error { tran := db.WithContext(ctx.Context()).Begin() + // Ensure transaction rollback on panic + defer func() { + if r := recover(); r != nil { + tran.Rollback() + } + }() if tran = tran.Exec("SELECT pg_sleep(50)"); tran.Error != nil { + tran.Rollback() return tran.Error } if tran = tran.Commit(); tran.Error != nil { + tran.Rollback() return tran.Error } return nil }middleware/static/static.go (1)
Line range hint
117-147: Consider documenting context handling best practicesWhile the changes to use
RequestCtx()are correct, consider adding documentation about:
- The performance implications of context handling in static file serving
- Best practices for context propagation in middleware
- Guidelines for when to use
RequestCtx()vs other context methodsThis will help maintainers and contributors understand the architectural decisions behind these changes.
middleware/adaptor/adaptor.go (1)
Line range hint
37-111: Architectural consistency in context handlingThe consistent transition from
Context()toRequestCtx()across the adaptor package strengthens the middleware's context handling capabilities. This change properly supports the PR's objective of adding context support for RequestID middleware while maintaining the integrity of the net/http to Fiber adaptation layer.Consider documenting these context handling patterns in the package documentation to help maintainers understand the correct usage of
RequestCtx()vsContext().bind.go (1)
Line range hint
98-166: Architecture Feedback: Good progress on context standardizationThe consistent update of context handling across all binding methods is a positive architectural change that:
- Standardizes the context access pattern
- Prepares the groundwork for RequestID middleware enhancement
- Maintains backward compatibility while improving the codebase
Consider documenting these context-related changes in the framework's migration guide to help users understand the standardized approach.
redirect.go (1)
144-146: Consider improving error handling in content type parsing.While the context change is correct, the content type parsing and binding operations silently ignore potential errors. Consider adding error logging or handling for better debugging and reliability.
Example improvement:
- ctype := utils.ToLower(utils.UnsafeString(r.c.RequestCtx().Request.Header.ContentType())) - ctype = binder.FilterFlags(utils.ParseVendorSpecificContentType(ctype)) + ctype := utils.ToLower(utils.UnsafeString(r.c.RequestCtx().Request.Header.ContentType())) + if ctype == "" { + // Log or handle empty content type + ctype = MIMEApplicationForm // or appropriate default + } + ctype = binder.FilterFlags(utils.ParseVendorSpecificContentType(ctype))ctx_interface_gen.go (1)
54-55: LGTM: Consistent method namingThe renaming from
SetUserContext()toSetContext()maintains consistency with theContext()getter method and follows Go's standard naming patterns.Consider adding a context key type and constants for request ID to prevent key collisions:
type contextKey string const ( RequestIDKey contextKey = "requestID" )docs/whats_new.md (1)
232-234: Improve clarity of context-related changesThe sentence structure could be improved to better convey these important breaking changes. Consider adding commas and restructuring for clarity.

1497-1508: Add usage example for RequestCtx()The documentation would benefit from including a practical example showing how to use the RequestCtx() method, particularly demonstrating its compatibility with the context.Context interface.
Consider adding this example:
+```go title="Example" +app.Get("/", func(c fiber.Ctx) error { + // Get the raw RequestCtx + reqCtx := c.RequestCtx() + + // Use it with context.Context compatible APIs + ctx := reqCtx.UserValue("context").(context.Context) + + // Or set a deadline + deadline := time.Now().Add(1 * time.Second) + reqCtx.SetDeadline(deadline) + + return nil +}) +``` <details> <summary>🧰 Tools</summary> <details> <summary>🪛 LanguageTool</summary> [typographical] ~1505-~1505: Consider adding a comma here.

(PLEASE_COMMA) </details> </details> --- `1911-1922`: **Enhance SetContext example with practical use case** While the current example shows the basic usage, it would be more helpful to demonstrate a practical use case with context values and cancellation. Consider expanding the example: ```diff ```go title="Example" app.Get("/", func(c fiber.Ctx) error { - ctx := context.Background() - c.SetContext(ctx) - // Here ctx could be any context implementation + // Create a context with cancellation + ctx, cancel := context.WithCancel(context.Background()) + defer cancel() + + // Add values to context + ctx = context.WithValue(ctx, "userID", "123") + + // Set the enhanced context + c.SetContext(ctx) + + // Use the context values in your handler + if userID, ok := ctx.Value("userID").(string); ok { + return c.SendString("Processing request for user: " + userID) + } // ... })ctx.go (2)
391-397: Consider adding error logging for type assertion.The implementation is solid but could benefit from debug-level logging when type assertion fails, helping with troubleshooting in production.
func (c *DefaultCtx) Context() context.Context { ctx, ok := c.fasthttp.UserValue(userContextKey).(context.Context) if !ok { + if ctx != nil { + c.app.config.Logger.Debugf("Failed to assert stored context value to context.Context") + } ctx = context.Background() c.SetContext(ctx) } return ctx }
403-406: Add nil check for context parameter.While the current implementation works, adding a nil check would prevent potential issues and provide better error feedback.
func (c *DefaultCtx) SetContext(ctx context.Context) { + if ctx == nil { + panic("nil context provided to SetContext") + } c.fasthttp.SetUserValue(userContextKey, ctx) }ctx_test.go (2)
Line range hint
855-874: Consider adding error cases to Context() testsWhile the test covers the basic functionality well, consider adding test cases for:
- Context cancellation scenarios
- Timeout scenarios
- Error propagation through context chain
t.Run("CancelledContext", func(t *testing.T) { t.Parallel() ctx, cancel := context.WithCancel(context.Background()) cancel() c.SetContext(ctx) require.Error(t, ctx.Err()) })
3223-3225: Fix indentation in test assertionThe indentation is inconsistent with the rest of the file.
- require.Equal(t, "public, max-age=100", string(c.RequestCtx().Response.Header.Peek(HeaderCacheControl)), "CacheControl Control") - require.Equal(t, StatusOK, c.Response().StatusCode()) + require.Equal(t, "public, max-age=100", string(c.RequestCtx().Response.Header.Peek(HeaderCacheControl)), "CacheControl Control") + require.Equal(t, StatusOK, c.Response().StatusCode())middleware/requestid/requestid.go (1)
64-64: Avoid logging errors in utility functionsLogging errors within utility functions can lead to unnecessary log output and might not be appropriate at this abstraction level. Consider handling the unsupported type without logging.
Modify the default case to handle unsupported context types gracefully:
default: - log.Errorf("Unsupported context type: %T", c) + // Unsupported context type; return empty string }

Let's verify that the proxy functionality remains intact after this change:
ctx.go (2)
385-387: LGTM! Clear and concise implementation.
The method provides clean access to the underlying fasthttp context with appropriate documentation.
1192-1193: LGTM! Good refactoring for consistency.
The change to use RequestCtx() aligns with the new context access pattern while maintaining the same efficient implementation.
ctx_test.go (3)
846-853: LGTM: Test coverage for RequestCtx() is adequate
The test verifies the basic functionality of RequestCtx() by checking the returned type. The test is simple but sufficient for this getter method.
875-886: LGTM: SetContext test provides good coverage
The test properly verifies that context values are maintained after setting a new context. Good use of test utilities and assertions.
Line range hint 888-923: Excellent concurrent request testing
The test thoroughly verifies context isolation between multiple concurrent requests using parallel subtests. Good practices:
- Uses t.Parallel() for concurrent testing
- Verifies proper status codes
- Checks response body content
- Tests multiple requests (1-10)

Insufficient test coverage for context propagation across middleware chains
The current tests do not cover context propagation across multiple middleware components. Please add comprehensive tests to ensure context values are properly preserved throughout the middleware chain.

🛠️ Refactor suggestion
Use any instead of interface{}
Since Go 1.18, it's recommended to use any instead of interface{} for improved code readability.
Apply this diff to update the function signature:
-func FromContext(c interface{}) string {
+func FromContext(c any) string {📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

52-53: Enhance the context support documentationWhile the introduction of context support is clear, consider adding more details about:
- Why this change is beneficial (e.g., better integration with Go's standard context)
- Migration notes for users upgrading from v2
Consider expanding the text like this:
-In version v3, Fiber will inject `requestID` into the built-in `Context` of Go. +In version v3, Fiber injects `requestID` into Go's built-in `Context`, enabling better integration with standard Go packages and improving request tracing across service boundaries. If you're upgrading from v2, you'll need to update your code to use `c.Context()` instead of directly accessing the context.
54-60: Add error handling to the example codeThe example demonstrates the new context usage correctly, but it would be more complete with error handling for cases where the requestID might not be present in the context.
Consider updating the example like this:
func handler(c fiber.Ctx) error { id := requestid.FromContext(c.Context()) + if id == "" { + // Handle case where requestID is not found + log.Printf("Warning: No request ID found in context") + id = "unknown" + } log.Printf("Request ID: %s", id) return c.SendString("Hello, World!") }

Description
In most business project scenarios of Go, it is a simple process from router to controller to service layer. Fiber is the operation of the routing layer, and we will convert Fiber's ctx into Go's built-in
Contextat the controller layer. Moreover, GO's built-inContextis more concurrent and secure at the service layer.To ensure link tracing of service invocations in the service layer, the
requestIDneeds to be passed to the service layer. Therefore, here we optimize Fiber'sUserContextto inject therequestIDinto itFixes #3175
