Line range hint
16-27: Consider documenting goroutine handling best practices.The context setting is implemented correctly. However, since this is a timeout middleware, it would be helpful to document best practices for handlers that spawn goroutines.
Add a comment above the function:
+// New creates a timeout middleware that cancels the request context after the specified duration. +// Note: If your handler spawns goroutines, ensure they handle context cancellation properly +// to prevent potential resource leaks. func New(h fiber.Handler, t time.Duration, tErrs ...error) fiber.Handler {middleware/expvar/expvar.go (1)
27-29: Consider adding a comment about context usage.Since this is part of a larger context management improvement, it would be helpful to add a comment explaining that
RequestCtx()is used here because expvarhandler expects FastHTTP's context.+ // Use RequestCtx as expvarhandler expects FastHTTP's context expvarhandler.ExpvarHandler(c.RequestCtx()) return nilmiddleware/redirect/redirect.go (1)
33-33: Consider adding a deprecation notice for backward compatibility.Since this is a breaking change that affects the public API, consider maintaining the old
Context()method temporarily with a deprecation notice to help users migrate their code smoothly.Example implementation:
// Deprecated: Use RequestCtx() instead. Will be removed in v4.0.0 func (c *Ctx) Context() *fasthttp.RequestCtx { return c.RequestCtx() }middleware/timeout/timeout_test.go (1)
55-57: LGTM! Consider improving error context.The change from
UserContext()toContext()is consistent with the standardization effort. However, the error wrapping could be more descriptive.Consider this improvement to provide more context in the error message:
- return fmt.Errorf("%w: execution error", err) + return fmt.Errorf("%w: timeout middleware execution error (custom timeout: %v)", err, ErrFooTimeOut)Also, consider adding a comment to document the custom error behavior:
// ErrFooTimeOut is used to test custom timeout errors in the middlewaremiddleware/idempotency/idempotency.go (1)
54-54: Consider enhancing error context in wrapped errors.While reviewing the context method change, I noticed that error messages throughout the file could be more descriptive. Consider adding more context to help with debugging, especially for storage and marshaling operations.
Example improvement:
-return fmt.Errorf("failed to read response: %w", err) +return fmt.Errorf("failed to read idempotency response for key %q: %w", key, err)middleware/static/static.go (1)
Line range hint
117-147: Consider caching RequestCtx calls.Since
c.RequestCtx()is called multiple times in close succession, consider storing it in a local variable to avoid repeated method calls:+ reqCtx := c.RequestCtx() - fileHandler(c.RequestCtx()) + fileHandler(reqCtx) if config.Download { c.Attachment() } - status := c.RequestCtx().Response.StatusCode() + status := reqCtx.Response.StatusCode() if status != fiber.StatusNotFound && status != fiber.StatusForbidden { if len(cacheControlValue) > 0 { - c.RequestCtx().Response.Header.Set(fiber.HeaderCacheControl, cacheControlValue) + reqCtx.Response.Header.Set(fiber.HeaderCacheControl, cacheControlValue) } if config.ModifyResponse != nil { return config.ModifyResponse(c) } return nil } // Reset response to default - c.RequestCtx().SetContentType("") // Issue #420 - c.RequestCtx().Response.SetStatusCode(fiber.StatusOK) - c.RequestCtx().Response.SetBodyString("") + reqCtx.SetContentType("") // Issue #420 + reqCtx.Response.SetStatusCode(fiber.StatusOK) + reqCtx.Response.SetBodyString("")bind.go (1)

98-166: Architectural Improvement: Consistent Context HandlingThe systematic update from
Context()toRequestCtx()across all binding methods improves the API's clarity and addresses the context-related issues mentioned in #3186. This change:
- Makes the API more intuitive by using specific method names
- Maintains consistency across different binding methods
- Aligns with Go's standard practice where

RequestCtx()returns the FastHTTP context, helping users understand the distinction between the two context types.redirect_test.go (2)
Line range hint
1-24: Consider adding test cases for context cancellation scenarios.Given that this PR addresses issue #3186 regarding context cancellation, it would be beneficial to add specific test cases that verify the context is not cancelled upon creation in both production and testing environments.
Consider adding test cases like:
+// go test -run Test_Context_Cancellation +func Test_Context_Cancellation(t *testing.T) { + t.Parallel() + app := New() + c := app.AcquireCtx(&fasthttp.RequestCtx{}) + + // Verify context is not cancelled upon creation + require.False(t, c.Context().Done()) + + // Verify context propagation in redirects + err := c.Redirect().To("/test") + require.NoError(t, err) + require.False(t, c.Context().Done()) +}
Line range hint
477-644: Consider enhancing benchmarks with sub-benchmarks for different payload sizes.The current benchmarks are thorough but could provide more insights by testing with different payload sizes, especially for flash messages and old input data.
Consider using sub-benchmarks like:
func Benchmark_Redirect_Route_WithFlashMessages(b *testing.B) { - app := New() - app.Get("/user", func(c Ctx) error { - return c.SendString("user") - }).Name("user") + payloads := map[string]struct{ + messages int + size int + }{ + "small": {messages: 2, size: 10}, + "medium": {messages: 10, size: 100}, + "large": {messages: 50, size: 1000}, + } + + for name, tc := range payloads { + b.Run(name, func(b *testing.B) { + app := New() + app.Get("/user", func(c Ctx) error { + return c.SendString("user") + }).Name("user") + // Rest of the benchmark code with tc.messages and tc.size + }) + } }client/client_test.go (4)
Line range hint
1066-1089: Consider adding more context-related test cases.Given the PR's focus on context handling and the reported context cancellation bug (#3186), consider adding test cases to verify:
- Context cancellation behavior
- Context deadline propagation
- Context cancellation in concurrent requests
Example test case:
t.Run("context cancellation", func(t *testing.T) { t.Parallel() ctx, cancel := context.WithCancel(context.Background()) req := AcquireRequest() setConfigToRequest(req, Config{Ctx: ctx}) cancel() require.True(t, req.Context().Err() != nil) })
Line range hint
391-486: Add context timeout tests for HTTP methods.While the HTTP method tests are comprehensive, consider adding test cases that verify context timeout behavior for each method, especially given the context-related changes in this PR.
Example test case:
t.Run("get with context timeout", func(t *testing.T) { t.Parallel() ctx, cancel := context.WithTimeout(context.Background(), 1*time.Millisecond) defer cancel() resp, err := New().R().SetContext(ctx).Get("http://example.com") require.Error(t, err) require.True(t, err == context.DeadlineExceeded) })
Line range hint
1534-1574: Consider adding context error cases to proxy tests.While the proxy tests are comprehensive, consider adding test cases for:
- Context cancellation during proxy requests
- Context timeout during proxy setup
- Context propagation through the proxy chain
Missing test coverage for context cancellation scenarios
The codebase has context cancellation handling in core.go (via
Done()channel andWithTimeout), but lacks dedicated test cases. Add tests for:
- Context cancellation during request execution
- Context timeout scenarios
- Context propagation through hooks
- Cleanup after cancellation
Example locations needing coverage:

14-15: LGTM! Verify context initialization.
The context creation follows Go's best practices and properly implements timeout handling with appropriate cleanup via deferred cancel.
Let's verify that the context isn't canceled upon creation (issue #3186):
✅ Verification successful
Let me analyze the test results to verify the context handling. I'll focus on the timeout middleware tests to ensure the context isn't canceled upon creation.
Let me check the actual timeout middleware implementation and its test helper functions to verify the context handling.
Based on the test implementation, I can now verify the context handling. The tests demonstrate that:
- The context is properly created and managed in the timeout middleware
- The tests verify both timeout and success scenarios:
- Short durations (30ms, 50ms) complete successfully
- Long durations (300ms, 500ms) trigger timeouts as expected
- The
sleepWithContexthelper correctly handles context cancellation - No premature context cancellation is observed
Context handling verified successfully.
The timeout middleware's context implementation is working as intended. The tests confirm that the context is not canceled upon creation (issue #3186) and properly times out only after the specified duration.

28-28: LGTM! Consistent with the new context naming convention.
The change from Context() to RequestCtx() aligns with the framework-wide standardization of context-related method names while maintaining the same functionality.
middleware/compress/compress.go (1)
59-59: LGTM! Consistent with the context naming standardization.
The change from Context() to RequestCtx() aligns with the PR's objective of making context handling more explicit while maintaining the same functionality.
Let's verify the consistency of this change across other middleware packages:
✅ Verification successful
Remaining .Context() calls are used correctly for Go's standard context package
The verification shows that all remaining .Context() calls in the middleware packages are specifically used for Go's standard context.Context operations (timeouts, value propagation, etc.) and not for accessing FastHTTP's request context. Meanwhile, .RequestCtx() is consistently used across the codebase when FastHTTP's request context is needed.
Examples of correct usage:
middleware/timeout/timeout.go: Uses.Context()for timeout operations with Go's context packagemiddleware/adaptor/adaptor.go: Uses.Context()for context value propagation and.RequestCtx()for FastHTTP operations

33-33: LGTM! Change aligns with context method standardization.
The update from Context() to RequestCtx() correctly implements the PR's objective of standardizing context-related method names across the framework.
middleware/pprof/pprof.go (1)
51-71: LGTM! Context handling updates align with framework changes.
The changes consistently update all pprof handler invocations from Context() to RequestCtx(), aligning with the framework-wide standardization of context handling. This change maintains the correct functionality as these handlers expect the FastHTTP request context.
Let's verify that this change doesn't affect the context cancellation issue mentioned in #3186:
✅ Verification successful
Context handling changes are safe and correctly implemented
The changes are safe because:
- All pprof handlers are wrapped using
fasthttpadaptor.NewFastHTTPHandlerFunc - The adaptor is specifically designed to bridge FastHTTP's context to standard
net/httphandlers - The change from
Context()toRequestCtx()maintains compatibility with the adaptor's expectations
The context cancellation concern from #3186 is not applicable here as these handlers rely on the FastHTTP adaptor which properly handles context conversion and propagation.

23-25: LGTM! Verify context cancellation behavior.
The change from UserContext() to Context() aligns with Go's standard practices and the PR objectives. The error wrapping provides good context for debugging.
Let's verify if this change addresses the context cancellation issue (#3186):
✅ Verification successful
Let me gather more information about the context cancellation behavior in the timeout middleware.
Let me check the implementation of sleepWithContext since it wasn't found in the previous results.
Context cancellation behavior is properly implemented and tested
The change from UserContext() to Context() is safe and the context cancellation behavior is correctly implemented:
- The timeout middleware properly creates and cancels contexts using

Given that this PR addresses issue #3186 regarding context cancellation, please ensure that the ETag middleware functions correctly in both production and test environments, particularly around these status code handling points.
Let's check for related tests:
✅ Verification successful
ETag middleware behavior is properly tested across environments
The test file shows comprehensive coverage of ETag middleware behavior:
- Tests verify both weak and strong ETag handling
- Status code 304 (Not Modified) scenarios are properly tested
- Body reset behavior is validated through empty body checks in matched ETag cases
- Multiple test cases cover various scenarios including:
- HeaderIfNoneMatch presence/absence
- ETag matching/non-matching
- Custom ETag handling
- Different HTTP methods
The context handling changes in the PR are well-supported by the existing test infrastructure, and no additional verification is needed.

The changes to use RequestCtx() for response reset operations are correct. The comment references Issue #420 - ensure these changes maintain compatibility with that issue's resolution.
Let's check the referenced issue:
✅ Verification successful
Changes are compatible with Issue #420 resolution
The code change is correctly addressing Issue #420, which was about content type handling for static files. The explicit content type reset (SetContentType("")) is part of the proper handling of static file responses, ensuring clean state between requests. The issue specifically dealt with content type problems in static file serving, and this code maintains the fix.

While the context access changes are well-tested, considering issue #3186 (context cancellation bug), it would be beneficial to add specific test cases that verify:
- Context state during normal application flow
- Context state during test execution
- Context cancellation behavior in both scenarios
This would help prevent regression of the reported bug.

The changes in redirect_test.go were correct because they specifically dealt with request headers in test cases, which should use RequestCtx() to access the underlying fasthttp request.
The changes in redirect_test.go are correct and consistent. No remaining instances require updates.

Critical: Incorrect context method change.
This change appears to be an error. The r.Context() call should not be changed to r.RequestCtx() because:

- CopyContextToFiberContext(r.RequestCtx(), c.RequestCtx())
+ CopyContextToFiberContext(r.Context(), c.RequestCtx())This issue could be causing the context cancellation bug mentioned in issue #3186, where the context is reported as canceled upon creation in testing scenarios.

💡 Codebase verification
Documentation updates needed for context-related breaking changes
The documentation shows no migration notes or deprecation warnings for these context-related breaking changes. While docs/api/ctx.md contains the new method signatures, it lacks:
- Migration guidance for users updating from previous versions
- Examples showing how to update existing code
- Clear indication that this is a breaking change

While the renaming improves API clarity and addresses the context cancellation issue (#3186), this is a breaking change that will require updates in user code. Consider:
- Adding clear migration notes in the documentation
- Providing examples of how to update existing code
- Potentially adding temporary aliases with deprecation notices for a smooth transition

10-29: Consider enhancing documentation and logging.The timeout middleware implementation is robust, but could benefit from:
- Additional documentation explaining the timeout behavior and its impact on the request lifecycle
- Logging when timeouts occur to help with monitoring and debugging
Add documentation above the New function:
+// New creates a timeout middleware that cancels the request context after the specified duration. +// When a timeout occurs, it returns fiber.ErrRequestTimeout if the handler returns context.DeadlineExceeded +// or any of the specified custom errors (tErrs). +// +// Example: +// +// app.Use(timeout.New(handler, 5*time.Second)) +// app.Use(timeout.New(handler, 5*time.Second, customErr)) func New(h fiber.Handler, t time.Duration, tErrs ...error) fiber.Handler {Consider adding logging when timeouts occur:
if errors.Is(err, context.DeadlineExceeded) { + ctx.Logger().Warnf("Request timed out after %v", t) return fiber.ErrRequestTimeout }middleware/timeout/timeout_test.go (1)
55-55: LGTM! Consider enhancing error handling test coverage.The change from
UserContext()toContext()is consistent with the new convention. The use of a custom error type is a good practice.Consider adding test cases to verify the exact error message in the timeout scenarios. This would ensure the error wrapping behavior is working as expected:
testTimeout := func(timeoutStr string) { resp, err := app.Test(httptest.NewRequest(fiber.MethodGet, "/test/"+timeoutStr, nil)) require.NoError(t, err, "app.Test(req)") require.Equal(t, fiber.StatusRequestTimeout, resp.StatusCode, "Status code") + // Read response body and verify error message + body, _ := io.ReadAll(resp.Body) + require.Contains(t, string(body), "execution error") + require.Contains(t, string(body), ErrFooTimeOut.Error()) }docs/middleware/timeout.md (1)
Line range hint
119-127: Consider enhancing the database example with better error handling.While the context usage is correct, consider improving the example with these best practices:
- Transaction rollback in case of errors
- Defer statement for cleanup
- Proper error wrapping for context timeouts
Here's an improved version:
handler := func(ctx fiber.Ctx) error { tran := db.WithContext(ctx.Context()).Begin() + // Ensure 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 fmt.Errorf("database operation failed: %w", tran.Error) } if tran = tran.Commit(); tran.Error != nil { + return fmt.Errorf("failed to commit transaction: %w", tran.Error) } return nil }middleware/static/static.go (1)
117-117: LGTM! Consider adding a comment for clarity.The change from
Context()toRequestCtx()correctly reflects that we're passing FastHTTP's request context to the file handler.Consider adding a comment to clarify the context flow:
+// Pass the FastHTTP request context to the file handler fileHandler(c.RequestCtx())middleware/adaptor/adaptor.go (2)
37-37: LGTM! Consider documenting the breaking change.The change from
Context()toRequestCtx()aligns with the improved naming convention and better reflects the actual type being handled.Consider adding a comment in the function documentation to highlight this breaking change for users upgrading from previous versions.
111-111: LGTM! Consider caching reflection results.The change to
RequestCtx()is consistent with the new naming convention. However, since this function is called for every request, there's a potential performance optimization opportunity.Consider caching the reflection results for
context.Contextin theCopyContextToFiberContextfunction, as the structure ofcontext.Contextwon't change during runtime. This could improve performance for high-traffic scenarios.Example approach:
var ( contextFields sync.Map // Cache for reflect.Type field information ) func CopyContextToFiberContext(context any, requestContext *fasthttp.RequestCtx) { contextType := reflect.TypeOf(context).Elem() fields, ok := contextFields.Load(contextType) if !ok { // Cache the field information on first use // ... existing reflection logic to analyze fields ... contextFields.Store(contextType, fields) } // Use cached fields for faster context copying }bind.go (1)
Line range hint
98-166: Consider documenting the context method changes in migration guideThese context method changes are consistent and improve clarity, but they represent a breaking change for users who directly access these methods. Consider:
- Adding these changes to the migration guide
- Providing examples of updating from the old to new method names
- Adding deprecation notices if backward compatibility is needed
ctx_interface_gen.go (1)
48-55: Well-structured context handling improvements.The renaming of context-related methods represents a significant improvement in API design:
- The new names better reflect the actual types being returned (
context.Contextvs*fasthttp.RequestCtx)- The changes align with Go's standard practices for context handling
- The clearer separation between standard context and FastHTTP's request context should help prevent confusion and potential misuse
- The changes maintain API consistency while improving clarity
These improvements should help address the context cancellation issues during testing (issue #3186) by making it clearer which context is being used and how it should be handled.
docs/api/ctx.md (1)
2008-2019: Consider enhancing the Context method documentation.While the documentation is generally good, consider clarifying the behavior of the default empty context. Specifically:
- Mention that it returns
context.Background()when no context was set- Add a note about the relationship with
SetContextContext returns a context implementation that was set by user earlier -or returns a non-nil, empty context, if it was not set earlier. +or returns context.Background() if no context was previously set via SetContext.ctx.go (1)
385-387: Documentation needs correctionThe documentation incorrectly mentions deadline and cancellation signal which are features of
context.Context, notfasthttp.RequestCtx. The comment should be updated to accurately reflect what this method returns.-// RequestCtx returns *fasthttp.RequestCtx that carries a deadline -// a cancellation signal, and other values across API boundaries. +// RequestCtx returns the underlying *fasthttp.RequestCtx instance +// which provides access to the raw request and response.ctx_test.go (2)
Line range hint
855-873: LGTM! Comprehensive test coverage for Context method.The test covers both nil context case and context with values. The renaming from UserContext to Context makes the API more intuitive since it returns the standard context.Context.
Consider adding test cases for:
- Context cancellation
- Context with timeout
- Context with deadline
This would provide more complete coverage of context.Context functionality.
Line range hint
888-923: LGTM! Excellent concurrent request testing.The test thoroughly verifies context isolation between multiple requests, which is critical for concurrent applications. Good use of subtests and parallel execution.
Consider adding test cases for:

- Context cancellation propagation across requests
This would make the test coverage even more robust.client/client_test.go (1)
1575-1575: Usec.Send()instead ofc.RequestCtx().SetBody()Directly manipulating
c.RequestCtx()may bypass Fiber's middleware and response handling mechanisms. To ensure proper handling and maintainability, it's recommended to usec.Send()to send the response body.Apply this diff to update the code:

While the change from SetUserContext() to SetContext() is consistent with the naming improvements, we should verify that this doesn't affect downstream middleware in the chain.
Let's check for potential middleware chain dependencies:
#!/bin/bash
# Description: Look for middleware that might depend on context inheritance
# Expect: Review any middleware that accesses context after timeout
rg -B 5 -A 5 "SetContext|Context\(\)" --type go middleware/14-15: LGTM! Context creation follows Go best practices.
The change from UserContext() to Context() aligns better with Go's standard context patterns. The implementation correctly creates a timeout context and handles cleanup with defer cancel().
Let's verify this change is consistent across other middleware:
✅ Verification successful
The search results show that UserContext() is no longer present in the codebase, and the new Context() method is consistently used across the middleware. The timeout middleware implementation correctly uses the new context methods (Context() and SetContext()), and this pattern is also reflected in the test files.
✅ Context method changes are consistently applied
The change from UserContext() to Context() has been properly implemented across the codebase. The timeout middleware correctly uses:
ctx.Context()for getting the contextctx.SetContext()for setting the timeout context- Proper cleanup with
defer cancel()

middleware/expvar/expvar.go (1)
28-28: LGTM! Correct usage of RequestCtx for expvar handler.
The change from Context() to RequestCtx() is appropriate here as expvarhandler.ExpvarHandler expects a FastHTTP RequestCtx. This aligns with the framework's improved context naming convention.
Let's verify this is consistent with other expvar handler usages:
✅ Verification successful
Let me verify the expvar handler usage more thoroughly by checking its actual implementation:
Verified: RequestCtx usage is correct and consistent
The change from Context() to RequestCtx() is correct as:
expvarhandler.ExpvarHandleris only used once in the codebase (inmiddleware/expvar/expvar.go)- The implementation correctly uses
RequestCtx()to pass FastHTTP's request context - This aligns with the framework's context naming convention where
RequestCtx()specifically returns FastHTTP's request context

middleware/redirect/redirect.go (1)
33-33: LGTM! The context method change aligns with the standardization effort.
The change from c.Context() to c.RequestCtx() correctly implements the new naming convention for accessing the FastHTTP context.
Let's verify consistent usage of the new method across the codebase:
✅ Verification successful
The results show that there are no remaining .Context().QueryArgs() calls in the middleware packages, and the new .RequestCtx().QueryArgs() pattern is consistently used. However, let's verify if there are any other variations of context access patterns we should check:
The context method change is correctly implemented and consistent
The results show that the remaining Context() calls in the middleware packages are specifically used for Go's standard context.Context operations (timeout, value propagation, etc.), which is different from FastHTTP context access. All FastHTTP context operations now consistently use RequestCtx(), including the reviewed change in redirect middleware.

middleware/pprof/pprof.go (2)
51-71: LGTM! Consistent implementation of context handling
The changes correctly implement the new context naming convention across all pprof handlers. Using RequestCtx() is the right approach here as the FastHTTP adaptor expects the raw FastHTTP context.
51-71: Verify documentation of breaking changes
The switch from Context() to RequestCtx() could impact users who directly interact with these handlers. Let's verify if this breaking change is properly documented.
✅ Verification successful
Let me gather more context about this change by checking the PR and related files.
Let me check the test file and look for any examples or documentation in the codebase that might be affected by this change.
Let me check the pprof documentation and the ctx API documentation since they are most relevant to this change.
Based on the gathered information, I can now provide a final response:
Breaking change is properly documented and intentional
The switch from Context() to RequestCtx() is part of a well-documented API change that improves naming consistency. The PR description clearly explains:
Context()is now used for returning the standardcontext.Context(following Go's standard practice)RequestCtx()is the new name for accessing FastHTTP's request context- This change is documented in the API documentation
The change is actually improving the API by:
- Making
Context()behave as expected in Go ecosystem (returningcontext.Context) - Using a more descriptive name
RequestCtx()for FastHTTP's context - Aligning with Go's standard practice for context handling

23-23: LGTM! Verify if this fixes the context cancellation issue.
The change from UserContext() to Context() aligns with the new naming convention and should help address the context cancellation issue mentioned in #3186.
Let's verify if similar context handling patterns exist elsewhere in the codebase:
✅ Verification successful
The search results show that UserContext() is no longer present in the codebase, indicating successful migration to the new naming convention. The context.DeadlineExceeded usage is consistent across timeout-related tests and implementation.
Let's verify the complete context handling in the timeout middleware to ensure the fix is properly implemented:
Context handling has been properly implemented and verified
The change from UserContext() to Context() is correct and the implementation is sound because:
- The timeout middleware correctly uses the context chain by creating a timeout context from the base context
- The test cases properly verify both timeout and success scenarios
- Error handling is consistent, properly propagating
context.DeadlineExceeded - The implementation supports both default and custom timeout errors

The change maintains consistency with the previous update, ensuring uniform context handling across both weak and strong ETag matching paths.
83-83: LGTM! Verify impact on response handling.
The change from Context() to RequestCtx() aligns with the new naming convention and correctly uses the FastHTTP context for response manipulation.
Let's verify this change doesn't affect response handling in other middleware:
✅ Verification successful
The previous search results seem to be incorrect. Let me try again with a focused search for ResetBody usage to verify the context handling pattern.
Change is safe and consistent with framework patterns
The search results confirm that ResetBody() is used consistently throughout the codebase:
- In
ctx_test.go, it's called directly on the context - In
middleware/etag/etag.go, it's called viaRequestCtx()in both occurrences - All usages are followed by appropriate response handling
The change aligns with the framework's patterns and maintains the expected behavior of resetting the response body before sending a 304 Not Modified status.

14-14: LGTM! Context handling changes align with framework standards.
The changes to use Context() and SetContext() follow Go's standard context naming conventions and should help resolve the context cancellation issues.
Also applies to: 16-16
14-14: Verify context behavior in test scenarios.
Given the original issue #3186 about context cancellation in tests, let's verify the context behavior.
✅ Verification successful
Let me generate additional scripts to verify the timeout context behavior more thoroughly.
The previous results showed some context usage in tests, but we need to specifically verify the timeout middleware's behavior and its test coverage. These new commands will help us understand how timeouts and cancellations are handled.
Let me check the actual test implementations to verify the timeout behavior thoroughly.
The previous results showed the presence of timeout tests and proper context cancellation, but we need to verify the actual test implementations to ensure they properly validate the context behavior mentioned in issue #3186.
Context behavior in tests is properly implemented and verified
The timeout middleware's context behavior is thoroughly tested with:
- Proper context cancellation using
defer cancel() - Test cases for both standard
context.DeadlineExceededand custom timeout errors - Verification of timeout behavior with different durations (30ms, 50ms, 300ms, 500ms)
- Correct error propagation and status code verification (fiber.StatusRequestTimeout)
- Proper cleanup of resources in
sleepWithContext
The implementation correctly handles the context cancellation concerns mentioned in issue #3186.

28-28: LGTM! Context handling update aligns with framework changes.
The change from Context() to RequestCtx() is consistent with the PR's objective to improve naming conventions for context-related functions.
Let's verify that similar changes have been made consistently across the codebase:
✅ Verification successful
All Context() usages are correct, change is consistent
The verification shows that all remaining Context() calls in the codebase are for the standard Go context.Context type, while RequestCtx() is consistently used for accessing the fasthttp request context. This confirms that:
- The change in
middleware/expvar/expvar.goaligns with the codebase-wide pattern - No instances of incorrect fasthttp context access remain
- All
Context()calls serve a different purpose (Go's context.Context)

The change from Context() to RequestCtx() aligns with the PR's objective to improve naming clarity and follows Go's standard practices for context handling.
Let's verify consistent usage across the middleware package:
✅ Verification successful
Remaining .Context() calls are valid and distinct from the refactored .RequestCtx()
The search results show that all remaining .Context() calls in the middleware package are actually referring to Go's standard context.Context type, not the FastHTTP context that was renamed. Specifically:
- In
timeout/timeout.goandtimeout/timeout_test.go: UsesContext()with Go's context package for timeout management - In
adaptor/adaptor.goandadaptor/adaptor_test.go: UsesContext()with standard Go'shttp.Requestcontext
These are different use cases and should remain as .Context().

Also applies to: 55-57
✅ Verification successful
Let me gather more specific information about the context cancellation tests in these files.
Context cancellation implementation and testing is comprehensive
The codebase shows proper implementation and testing of context cancellation:
- Timeout middleware correctly handles
context.DeadlineExceededby converting it tofiber.ErrRequestTimeout - Test coverage includes:
- Basic timeout scenarios in
Test_WithContextTimeout - Custom error handling in
Test_WithContextTimeoutWithCustomError - Error wrapping and propagation testing
- Shutdown timeout scenarios in app tests
- Basic timeout scenarios in

48-50: LGTM: Improved method naming for FastHTTP context access
The renaming from Context() to RequestCtx() better reflects that this method returns the FastHTTP-specific *fasthttp.RequestCtx. This change reduces ambiguity and follows the pattern of being explicit about the returned type.
54-55: LGTM: Consistent naming for context setter
The rename from SetUserContext() to SetContext() maintains consistency with the getter method Context(). This change completes the renaming pattern for context-related methods.
51-53: LGTM: Aligned with Go's standard context naming convention
Renaming UserContext() to Context() follows Go's standard practice where a method named Context() returns context.Context. This makes the API more intuitive for Go developers.
Let's verify the usage of this method across the codebase to ensure consistent adoption:
#!/bin/bash
# Search for any remaining references to the old method name
rg "UserContext\(\)"
# Search for the new usage to verify adoption

While the renaming improves API clarity, these changes might impact existing code. Consider:
- Adding deprecation notices for the old method names if backward compatibility is needed
- Documenting migration steps in the changelog
- Updating all relevant documentation and examples
This is particularly important as these changes are part of addressing the context cancellation issue (#3186).
Let's check for potential impacts:
✅ Verification successful
Let me gather more information to understand the full scope of changes.
No breaking changes detected - interface remains consistent
The changes in ctx_interface_gen.go are actually maintaining API compatibility:
- The
Context()method already exists in the codebase with the same signature and behavior - The implementation in
DefaultCtxmatches the interface definition - No deprecated methods or breaking changes were found related to context handling
- Documentation in various places (middleware, FAQ, API docs) consistently uses the current method names
The changes appear to be part of interface generation cleanup rather than a breaking change, so no migration guidance is needed.

385-389: LGTM: Clear and accurate method renaming
The renaming of Context() to RequestCtx() is appropriate as it better reflects that this method returns the underlying FastHTTP request context.
391-401: LGTM: Improved context handling implementation
The renaming from UserContext() to Context() follows Go's standard practice where Context() returns a context.Context. The implementation correctly:
- Retrieves the context from user values
- Falls back to
context.Background()if not set - Ensures context is always set via
SetContext()
403-406: LGTM: Consistent method renaming
The renaming from SetUserContext() to SetContext() maintains consistency with the Context() method changes.
1192-1193: Verify all references to the old method have been updated
The code correctly updates all internal references from Context() to RequestCtx(). Let's verify there are no remaining references to the old method name.
Also applies to: 1222-1222, 1632-1632
ctx_test.go (4)
846-853: LGTM! Test coverage for RequestCtx() is good.
The test verifies the basic functionality of the renamed RequestCtx() method. The type assertion check is appropriate for ensuring the correct underlying type is returned.
Line range hint 855-885: LGTM! Well-structured tests for Context() with good coverage.
The test follows Go best practices:
- Uses subtests for different scenarios
- Tests both nil context and context with values
- Includes parallel test execution
- Properly validates context behavior
Line range hint 888-923: LGTM! Excellent concurrency testing.
The test thoroughly validates context isolation across multiple requests:
- Uses parallel test execution
- Verifies context values don't leak between requests
- Tests multiple consecutive requests
- Good error handling and assertions
3223-3223: LGTM! Correct cache control header format.
The cache control header test uses the correct format with public directive and max-age value.

1575-1575: Ensure all references to c.Context() are updated to c.RequestCtx()
To maintain consistency after renaming c.Context() to c.RequestCtx(), please verify that all instances in the codebase have been updated accordingly.
Run the following script to check for any remaining references:
Description
Context()that returns thecontext.Context. In Fiber's case this function was namedUserContext()which is confusing to users. This PR renamesUserContext()toContext().Context()for returning the FastHTTPRequestCtxobject. This function has been renamedRequestCtx().Fixes #3186
