57-68: Ensure thread safety when setting session tokens.Verification successful
The
Setmethod implementations found in the codebase indicate that thread safety measures are in place. Specifically:
- In
middleware/session/middleware.go, theSetmethod uses a mutex (m.mu.Lock()andm.mu.Unlock()) to ensure thread safety.- In
middleware/session/data.go, theSetmethod also uses a lock (d.Lock()andd.Unlock()) to ensure thread safety.These implementations confirm that the session management operations are thread-safe.

Known IssuesStorage Adapter UPSERT BehaviorThere is an issue with the way Fiber's storage adapters handle setting keys. The current operation for setting a key is an UPSERT, which means it will insert a new key if it does not exist or update it if it does. This can lead to issues in scenarios with simultaneous requests altering the same session. For example:
If the session destruction completes first, the inconsequential change could recreate the session, potentially preventing actions like logging out and posing security risks. Since this PR changes the session behavior to save and update on every request, it amplifies the problem if not addressed. |

middleware/csrf/session_manager.go (4)
21-32: Improved session manager initializationThe changes to
newSessionManagerare well-implemented:
- Removing the
k stringparameter simplifies the function.- Registering
sessionKeyTypeandTokenwith the session store ensures proper serialization/deserialization.These changes align well with the new session key management approach.
However, consider adding error handling for the type registration:
if err := s.RegisterType(sessionKeyType(0)); err != nil { // Handle or log the error } if err := s.RegisterType(Token{}); err != nil { // Handle or log the error }This would make the function more robust against potential registration failures.
37-52: Improved session retrieval logic with suggestionsThe changes to
getRawmethod are well-implemented:
- Prioritizing context-based session retrieval can improve performance.
- Fallback to store retrieval ensures compatibility with various session management scenarios.
However, there are a few areas for improvement:
Error handling: The error from
m.session.Get(c)is silently ignored. Consider logging this error or returning it to the caller.Potential refactoring: The token retrieval logic is duplicated. Consider refactoring to reduce duplication:
func (m *sessionManager) getToken(s fiber.Session) (Token, bool) { token, ok := s.Get(sessionKey).(Token) return token, ok } // In getRaw: var token Token var ok bool if sess := session.FromContext(c); sess != nil { token, ok = m.getToken(sess) } else { storeSess, err := m.session.Get(c) if err != nil { log.Warn("csrf: failed to get session from store: ", err) return nil } token, ok = m.getToken(storeSess) }This refactoring would make the code more maintainable and reduce the risk of inconsistencies.

12-95: LGTM: Enhanced Config struct with improved session managementThe changes to the
Configstruct significantly improve session management capabilities:
- The addition of
Next,ErrorHandler,IdleTimeout, andAbsoluteTimeoutfields enhances configurability and error handling.- Replacing
ExpirationwithIdleTimeoutandAbsoluteTimeoutprovides more granular control over session expiration.- The improved documentation for all fields enhances code readability and usability.
These changes align well with the PR objectives of improving session management and addressing inconsistencies in timeout handling.
Consider adding a note to the
AbsoluteTimeoutdocumentation to clarify its relationship withIdleTimeout. For example:// AbsoluteTimeout defines the maximum duration of the session before it expires. // // If set to 0, the session will not have an absolute timeout, and will expire after the idle timeout. // Note: This value should be greater than or equal to IdleTimeout. // // Optional. Default: 0 AbsoluteTimeout time.DurationThis addition would help prevent potential configuration errors.
Line range hint
135-190: LGTM: Improved configDefault with enhanced error handlingThe updates to
configDefaultfunction are well-aligned with the changes made to theConfigstruct:
- Proper handling of new fields like
IdleTimeoutandAbsoluteTimeout.- Addition of a safeguard to ensure
AbsoluteTimeoutis always greater than or equal toIdleTimeout.- Improved error messages for better debuggability.
These changes contribute to more robust session configuration.
Consider using
log.Panicinstead ofpanicfor consistency with the error handling approach used elsewhere in the package. This would allow for better error logging and potential recovery in production environments. For example:if cfg.AbsoluteTimeout > 0 && cfg.AbsoluteTimeout < cfg.IdleTimeout { log.Panic("[session] AbsoluteTimeout must be greater than or equal to IdleTimeout") }if len(selectors) != numSelectors { log.Panic("[session] KeyLookup must be in the format '<source>:<name>'") }default: log.Panic("[session] unsupported source in KeyLookup")This change would provide more consistent error handling throughout the package.

125-125: ApproveIdleTimeoutinConfigDefault, suggest documenting rationale.The change from
ExpirationtoIdleTimeoutinConfigDefaultis consistent with the struct modification. The default value of 30 minutes is reasonable for CSRF token validity.Consider adding a comment explaining the rationale for choosing 30 minutes as the default
IdleTimeout. This would provide valuable context for developers using or maintaining the middleware.
150-151: ApproveIdleTimeoutcheck, suggest minor improvement.The change from
ExpirationtoIdleTimeoutin theconfigDefaultfunction is consistent with the previous modifications. The logic correctly ensures that a default value is set ifIdleTimeoutis not properly configured.Consider changing the condition to explicitly check for negative values:
-if cfg.IdleTimeout <= 0 { +if cfg.IdleTimeout < 0 {This change would allow users to set
IdleTimeoutto 0 if they want to disable the timeout feature. If this is not the intended behavior, please add a comment explaining why 0 is not a valid value.middleware/session/middleware.go (4)
12-39: LGTM: Well-structured Middleware type with proper concurrency considerations.The Middleware struct and related constants are well-designed. The use of sync.RWMutex for concurrency safety and sync.Pool for instance reuse are good practices.
Consider adding a brief comment explaining the purpose of the
destroyedfield in the Middleware struct for better clarity.
41-108: LGTM: Well-implemented initialization functions with proper session lifecycle management.The
NewandNewWithStorefunctions provide a flexible way to initialize the session middleware. The handler correctly manages the session lifecycle, including initialization and cleanup.Consider adding error handling for the case where
NewWithStorefails to create a store. Currently, ifNewStore(cfg)were to return an error (which it doesn't in the current implementation), it would be silently ignored.
235-289: LGTM: Well-implemented session management methods.The Destroy, Fresh, ID, and Reset methods provide necessary session management operations and are correctly implemented.
Consider adding a brief comment explaining the purpose of the
destroyedflag in the Destroy method, and how it interacts with other parts of the middleware (e.g., in the handler function).
1-301: Overall assessment: Well-implemented session middleware with room for minor improvements.This new session middleware implementation for Fiber is robust and well-structured. Key strengths include:
- Proper use of sync.Pool for performance optimization.
- Good concurrency safety with appropriate use of mutexes.
- Flexible configuration options.
- Comprehensive session management operations.
Areas for improvement:
- Error handling in the
initializeandacquireMiddlewaremethods could be more graceful to avoid potential panics in production.- Test coverage could be increased, particularly for error handling paths.
- Some additional documentation would improve code clarity, especially regarding the
destroyedflag and its implications.These improvements would further enhance the reliability and maintainability of the middleware. Overall, this is a solid implementation that provides a strong foundation for session management in Fiber applications.
Consider adding a middleware-specific logger or integrating with Fiber's logging system. This would allow for more granular control over log levels and could help with debugging in production environments without relying on panics for error reporting.

- Simplified session manager initialization.
- Consistent replacement of
ExpirationwithIdleTimeoutthroughout the CSRF middleware.- Better alignment with NIST guidelines on distinguishing between timeout and expiration.
These modifications enhance the security and consistency of the CSRF protection mechanism. The code is now more maintainable and adheres to best practices for session management.
Consider the following for future improvements:
- Implement the absolute timeout mechanism mentioned in the PR comments.

441-479: Approved: New methods for absolute session expirationThe addition of
absExpiration,isAbsExpired, andsetAbsExpirationmethods is a valuable improvement to the session management system. These methods provide an additional layer of control over session lifetimes, aligning well with the PR objectives.Consider adding a brief explanation in the package documentation about the difference between idle timeout and absolute expiration. For example:
/* Package session provides session management for Fiber applications. This package uses two types of session expiration: 1. Idle Timeout: The session expires after a period of inactivity. 2. Absolute Expiration: The session expires at a fixed point in time, regardless of activity. Idle Timeout is managed automatically, while Absolute Expiration can be set manually using the setAbsExpiration method. */ package sessionThis addition would provide clarity on the two expiration mechanisms and how they differ.

59-59: Consider clarifying IdleTimeout behavior in the legacy approachThe note about IdleTimeout behavior in the legacy approach is helpful. To further improve clarity, consider expanding this note to explain how the IdleTimeout behaves differently in the middleware handler approach. This will help users understand the key differences between the two approaches.
Consider adding the following information:
When using the legacy approach, the IdleTimeout will be updated when the session is saved. +When using the middleware handler approach, the IdleTimeout is automatically updated on each request.
132-148: Enhance Config struct documentationThe Config struct documentation is comprehensive, but it could benefit from additional context for the new timeout fields. This would help users understand the difference between IdleTimeout and AbsoluteTimeout and how they affect session behavior.
Consider adding brief descriptions to the IdleTimeout and AbsoluteTimeout fields:
type Config struct { // ... other fields ... - IdleTimeout time.Duration - AbsoluteTimeout time.Duration + IdleTimeout time.Duration // Maximum duration of inactivity before session expires + AbsoluteTimeout time.Duration // Maximum total duration of a session, regardless of activity // ... other fields ... }
207-218: Ensure consistent formatting for method signaturesThe method signatures in the Session Methods section are not consistently formatted. Some methods are on separate lines, while others are on the same line. Consistent formatting would improve readability.
Consider applying the following changes to ensure consistent formatting:
func (s *Session) Fresh() bool func (s *Session) ID() string -func (s *Session) Get(key string) any -func (s *Session) Set(key string, val any) -func (s *Session) Destroy() error -func (s *Session) Regenerate() error +func (s *Session) Get(key string) any +func (s *Session) Set(key string, val any) +func (s *Session) Destroy() error +func (s *Session) Regenerate() error func (s *Session) Release() func (s *Session) Reset() error -func (s *Session) Save() error -func (s *Session) Keys() []string +func (s *Session) Save() error +func (s *Session) Keys() []string func (s *Session) SetIdleTimeout(idleTimeout time.Duration)
397-418: Enhance custom types exampleThe example for registering custom types is helpful, but it could be more informative by demonstrating how to actually use the custom type in a session. This would provide a complete picture of how to work with custom types in sessions.
Consider expanding the example to show how to set and get a custom type in a session:
func main() { app := fiber.New() sessionMiddleware, sessionStore := session.NewWithStore() sessionStore.RegisterType(User{}) app.Use(sessionMiddleware) + app.Get("/", func(c fiber.Ctx) error { + sess := session.FromContext(c) + if sess == nil { + return c.SendStatus(fiber.StatusInternalServerError) + } + + // Set custom type in session + sess.Set("user", User{Name: "John Doe", Age: 30}) + + // Get custom type from session + if user, ok := sess.Get("user").(User); ok { + return c.SendString(fmt.Sprintf("User: %s, Age: %d", user.Name, user.Age)) + } + + return c.SendString("User not found in session") + }) app.Listen(":3000") }This enhancement demonstrates how to set and retrieve a custom type in a session, providing a more complete example for users.
423-437: Ensure consistent formatting for property descriptionsThe property descriptions in the Config table are not consistently formatted. Some end with periods, while others don't. Consistent formatting would improve readability and professionalism.
Consider applying the following changes to ensure consistent formatting:
-| **Storage** | `fiber.Storage` | Defines where session data is stored. | `nil` (in-memory storage) | -| **Next** | `func(c fiber.Ctx) bool` | Function to skip this middleware under certain conditions. | `nil` | -| **ErrorHandler** | `func(c fiber.Ctx, err error)` | Custom error handler for session middleware errors. | `nil` | -| **KeyGenerator** | `func() string` | Function to generate session IDs. | `UUID()` | -| **KeyLookup** | `string` | Key used to store session ID in cookie or header. | `"cookie:session_id"` | -| **CookieDomain** | `string` | The domain scope of the session cookie. | `""` | -| **CookiePath** | `string` | The path scope of the session cookie. | `"/"` | -| **CookieSameSite** | `string` | The SameSite attribute of the session cookie. | `"Lax"` | -| **IdleTimeout** | `time.Duration` | Maximum duration of inactivity before session expires. | `30 * time.Minute` | -| **AbsoluteTimeout** | `time.Duration` | Maximum duration before session expires. | `0` (no expiration) | -| **CookieSecure** | `bool` | Ensures session cookie is only sent over HTTPS. | `false` | -| **CookieHTTPOnly** | `bool` | Ensures session cookie is not accessible to JavaScript (HTTP only). | `true` | -| **CookieSessionOnly** | `bool` | Prevents session cookie from being saved after the session ends (cookie expires on close). | `false` | +| **Storage** | `fiber.Storage` | Defines where session data is stored | `nil` (in-memory storage) | +| **Next** | `func(c fiber.Ctx) bool` | Function to skip this middleware under certain conditions | `nil` | +| **ErrorHandler** | `func(c fiber.Ctx, err error)` | Custom error handler for session middleware errors | `nil` | +| **KeyGenerator** | `func() string` | Function to generate session IDs | `UUID()` | +| **KeyLookup** | `string` | Key used to store session ID in cookie or header | `"cookie:session_id"` | +| **CookieDomain** | `string` | The domain scope of the session cookie | `""` | +| **CookiePath** | `string` | The path scope of the session cookie | `"/"` | +| **CookieSameSite** | `string` | The SameSite attribute of the session cookie | `"Lax"` | +| **IdleTimeout** | `time.Duration` | Maximum duration of inactivity before session expires | `30 * time.Minute` | +| **AbsoluteTimeout** | `time.Duration` | Maximum duration before session expires | `0` (no expiration) | +| **CookieSecure** | `bool` | Ensures session cookie is only sent over HTTPS | `false` | +| **CookieHTTPOnly** | `bool` | Ensures session cookie is not accessible to JavaScript (HTTP only) | `true` | +| **CookieSessionOnly** | `bool` | Prevents session cookie from being saved after the session ends (cookie expires on close) | `false` |This change ensures all descriptions are consistently formatted without periods at the end.

109-110: LGTM with a minor suggestionThe addition of
IdleTimeoutin the configuration table is correct. However, consider enhancing the description to provide more context:- IdleTimeout | `time.Duration` | IdleTimeout is the duration of inactivity before the CSRF token will expire. | 30 * time.Minute | + IdleTimeout | `time.Duration` | IdleTimeout is the duration of inactivity before the CSRF token will expire. The token's expiration is extended by this duration with each request. | 30 * time.Minute |This additional information helps users understand the dynamic nature of the token expiration.
304-304: LGTM with a minor suggestion for clarityThe explanation of the token lifecycle accurately reflects the new behavior introduced by the
IdleTimeoutconfiguration. However, consider a small adjustment for even better clarity:- Tokens are valid until they expire or until they are deleted. By default, tokens are valid for 30 minutes, and each subsequent request extends the expiration by the idle timeout. The token only expires if the user doesn't make a request for the duration of the idle timeout. + Tokens are valid until they expire or until they are deleted. By default, tokens have an idle timeout of 30 minutes. Each request resets this timeout, extending the token's validity. The token only expires if no requests are made for the duration of the idle timeout.This adjustment more explicitly ties the concept to the
IdleTimeoutconfiguration and clarifies the reset behavior.middleware/session/store_test.go (2)
128-129: Ensure middleware is properly initialized in the testLines 128-129 create a new
Middlewareinstance withmiddleware := &Middleware{}and set it in the context's locals. To accurately simulate the middleware's behavior, ensure that the middleware is properly configured as it would be in a real application. This might involve initializing any necessary fields or using a constructor function if available.

Improve test coverage for error handling paths
The static analysis tool has identified several lines that are not covered by tests, primarily in error handling paths. This lack of coverage could lead to undetected issues in error scenarios. Consider adding test cases that exercise these error paths:
- Failure to get session from store (lines 48, 74, 93)
- Failure to save session (lines 78, 97)
- Session deletion (line 87)
Improving test coverage for these scenarios will enhance the reliability of the CSRF middleware and ensure that error handling behaves as expected in various situations.
Would you like assistance in generating test cases for these error handling paths?

33-43: Approved: Simplified sessionPool initializationThe change to
sessionPoolis a good optimization, directly returning a newSessioninstance. This simplifies the code and potentially improves performance by reducing the need for additional checks or initializations when acquiring a session from the pool.For consistency, consider updating the
byteBufferPoolin a similar manner:var byteBufferPool = sync.Pool{ New: func() any { - return new(bytes.Buffer) + return &bytes.Buffer{} }, }This change would make both pool initializations consistent in their approach.
46-61: Approved: Simplified acquireSession function with minor suggestionThe changes to the
acquireSessionfunction are appropriate and align well with the modifications to theSessionstruct. The removal of thebyteBuffercheck and settingfreshto true for newly acquired sessions are correct improvements.Consider improving error handling in the type assertion:
-s := sessionPool.Get().(*Session) //nolint:forcetypeassert,errcheck // We store nothing else in the pool +s, ok := sessionPool.Get().(*Session) +if !ok { + panic("invalid type in session pool") +}This change would make the code more robust against potential future modifications to the pool.
63-85: Approved: New Release method with clear documentationThe addition of the
Releasemethod is an excellent improvement for efficient resource management. The detailed documentation clearly explains its purpose and usage, which is crucial for preventing misuse.For consistency with other methods in the file, consider adding a usage example in the documentation:

saveSessionmethod is a great addition, providing a clear separation of concerns from theSavemethod. It handles the core logic of saving the session, including setting theidleTimeoutand encoding the data, which aligns well with the PR objectives of improving session management.Consider enhancing error handling by wrapping the error returned from

463-501: Approved: Enhanced session expiration management with suggestionThe addition of
absExpiration,isAbsExpired, andsetAbsExpirationmethods is an excellent improvement to the session management capabilities. These methods allow for more granular control over session expiration, supporting both idle timeout and absolute (hard) expiration policies. This aligns well with the PR objectives and follows best practices in session management.For consistency with other methods in the file, consider renaming
setAbsExpirationtosetAbsoluteExpiration:-func (s *Session) setAbsExpiration(absExpiration time.Time) { +func (s *Session) setAbsoluteExpiration(absExpiration time.Time) {This change would make the method name more explicit and consistent with the full terminology used in the comments.

35-62: Improved NewStore function with enhanced documentation and featuresThe renaming of
NewtoNewStoreand the addition of detailed documentation significantly improve the function's clarity and usability. The new absolute timeout handling is a valuable addition to session management.Consider updating the usage example in the documentation to reflect the new function name:
- store := session.New() + store := session.NewStore()

121-182: Improved getSession method with enhanced session managementThe additions to handle session freshness, expiration, and absolute timeouts significantly improve the session management capabilities. The error handling for session data decoding has also been enhanced.
However, there's a potential issue with error variable shadowing in the data decoding error handling. Consider the following change:
- err := sess.decodeSessionData(rawData) + decodeErr := sess.decodeSessionData(rawData) sess.data.Unlock() - if err != nil { + if decodeErr != nil { sess.mu.Unlock() - return nil, fmt.Errorf("failed to decode session data: %w", err) + return nil, fmt.Errorf("failed to decode session data: %w", decodeErr) }This change prevents shadowing the outer

Consider adding brief descriptions for each method.
To enhance the usefulness of the Signatures section, consider adding brief descriptions for each method. This would help users understand the purpose of each method at a glance. For example:
// Session Methods func (s *Session) Fresh() bool // Returns true if the session is new func (s *Session) ID() string // Returns the session ID func (s *Session) Get(key string) any // Retrieves a value from the session // ... (add descriptions for other methods)This addition would make the documentation more informative and user-friendly.

Comprehensive and informative Examples section.The Examples section provides a wide range of use cases, including the recommended middleware handler approach, custom storage implementation, session usage without middleware handler, and handling of custom types. The inclusion of security notices and middleware order information adds significant value.
Consider improving consistency of code comments across examples.
To enhance readability and maintain consistency, consider adding more inline comments to all example code snippets. This would help users understand the purpose of each code block more easily. For instance, in the "Middleware Handler (Recommended)" example:
// Initialize Fiber app app := fiber.New() // Create session middleware and store sessionMiddleware, sessionStore := session.NewWithStore() // Use session middleware app.Use(sessionMiddleware) // Use CSRF middleware with session store app.Use(csrf.New(csrf.Config{ Store: sessionStore, })) // Define route handler app.Get("/", func(c fiber.Ctx) error { // Get session from context sess := session.FromContext(c) if sess == nil { return c.SendStatus(fiber.StatusInternalServerError) } // ... (rest of the handler code) })Applying this level of commenting consistently across all examples would improve the overall documentation quality.

440-477: LGTM! Well-structured Config section.The Config section provides a comprehensive table of configuration options with descriptions and default values, followed by a code snippet showing the default configuration. This structure makes it easy for users to understand and customize the session middleware.
Consider clarifying some configuration option descriptions.
To enhance user understanding, consider refining the descriptions of some configuration options. For example:
- KeyLookup: Clarify that this is a string in the format "source:name" where source can be "header" or "cookie".
- CookieSameSite: Provide a brief explanation of what each possible value ("Lax", "Strict", "None") means.
- IdleTimeout and AbsoluteTimeout: Clarify the difference between these two timeout mechanisms.
For instance:
| **KeyLookup** | `string` | Key used to store session ID. Format: "source:name" (e.g., "cookie:session_id" or "header:X-Session-ID") | `"cookie:session_id"` | | **CookieSameSite** | `string` | SameSite attribute of the session cookie. Options: "Lax" (default, prevents CSRF in most cases), "Strict" (may break some functionalities), "None" (requires HTTPS) | `"Lax"` | | **IdleTimeout** | `time.Duration` | Maximum duration of inactivity before session expires. Resets on each request. | `30 * time.Minute` | | **AbsoluteTimeout** | `time.Duration` | Maximum total duration of a session, regardless of activity. Set to 0 for no expiration. | `0` (no expiration) |These clarifications would help users make more informed decisions when configuring the middleware.

23-23: LGTM: Consistent renaming ofNew()toNewStore()The changes in the
Test_Store_getSessionIDfunction correctly implement the renaming ofNew()toNewStore(). This modification is consistent across all test cases within the function, maintaining the intended functionality while updating the API.Also applies to: 36-38, 51-53
76-76: LGTM: Consistent renaming in Test_Store_GetThe change in the
Test_Store_Getfunction correctly implements the renaming ofNew()toNewStore(). This modification maintains consistency with the updated API.
96-96: LGTM: Consistent renaming in Test_Store_DeleteSessionThe change in the
Test_Store_DeleteSessionfunction correctly implements the renaming ofNew()toNewStore(). This modification maintains consistency with the updated API.
142-156: LGTM: Comprehensive test cases for Store.DeleteThe new
TestStore_Deletefunction is a valuable addition to the test suite. It covers two important scenarios:
- Attempting to delete a session with an empty ID, which correctly returns an
ErrEmptySessionIDerror.- Attempting to delete a non-existing session, which correctly doesn't return an error.
These test cases enhance the robustness of the session deletion functionality and provide good coverage for edge cases.
Line range hint
1-217: Overall assessment: Significant improvement in test coverageThe changes to
middleware/session/store_test.gorepresent a substantial enhancement to the test suite for session management. Key improvements include:
- Consistent renaming of
New()toNewStore()across all test cases.- Addition of new test functions that cover important scenarios:
TestStore_Get_SessionAlreadyLoadedTestStore_DeleteTest_Store_GetByIDThese additions significantly improve the test coverage for session creation, retrieval, manipulation, and deletion. They also address edge cases and error conditions, enhancing the overall robustness of the session management system.
The suggested minor improvements (using
NewStore()consistently and releasing acquired contexts) will further refine the test suite. Overall, these changes contribute to a more comprehensive and reliable testing framework for the session middleware.middleware/session/store.go (4)
16-20: LGTM: New error variables enhance error handlingThe introduction of
ErrSessionAlreadyLoadedByMiddlewareandErrSessionIDNotFoundInStore, along with the update toErrEmptySessionID, improves error handling specificity. The error messages are consistent and follow Go conventions.
35-62: LGTM: Improved NewStore function with enhanced documentation and functionalityThe renaming of
NewtoNewStoreimproves clarity. The added documentation, including parameters, return values, and usage examples, enhances developer understanding. The new absolute timeout handling aligns well with the PR objectives for improved session management.
77-104: LGTM: Enhanced Get method with improved error handlingThe addition of a check for sessions already loaded by middleware prevents potential issues with duplicate loading. The updated documentation clearly explains this new behavior, enhancing the method's usability and robustness.
237-255: LGTM: Enhanced Delete method with improved documentation and error handlingThe addition of detailed documentation, including parameters, return values, and usage examples, significantly improves the method's usability. The new error handling for empty session IDs enhances the robustness of the method.

125-176: LGTM! Well-structured Types section.The Types section clearly defines the Config, Middleware, Session, and Store structs, providing users with a comprehensive overview of the key components in the session middleware. The inclusion of code snippets for each type enhances understanding.
Line range hint
1-477: Excellent documentation update for the session middleware.This comprehensive update to the session middleware documentation significantly enhances its usefulness for Fiber users. Key strengths include:
- Detailed migration guide from v2 to v3.
- Clear explanations of new concepts like
IdleTimeoutandAbsoluteTimeout.- Comprehensive examples covering various use cases.
- Well-structured Config section with detailed explanations.
- Inclusion of important security notices and best practices.
The minor formatting and consistency issues identified earlier do not detract from the overall quality of the documentation. Once addressed, this will be an exemplary resource for developers using the Fiber framework.

58-60: Consider clarifying IdleTimeout behavior in the legacy approachThe note about IdleTimeout behavior in the legacy approach is helpful. To further improve clarity, consider expanding this note to explain how the IdleTimeout behaves when using the recommended middleware handler approach. This will help users understand the differences between the two approaches more clearly.
:::note When using the legacy approach, the IdleTimeout will be updated when the session is saved. +When using the recommended middleware handler approach, the IdleTimeout is automatically updated on each request. :::
132-147: Consider adding brief descriptions for Config struct fieldsTo enhance the documentation, consider adding brief descriptions for each field in the Config struct. This will help users understand the purpose and impact of each configuration option more easily.
For example:
type Config struct { // Storage defines where session data is stored Storage fiber.Storage // Next defines a function to skip this middleware when returned true Next func(fiber.Ctx) bool // Add descriptions for other fields... }
180-228: Enhance consistency in method descriptionsTo improve the documentation, consider adding brief descriptions for each method in the Signatures section, similar to the detailed explanation provided for the GetByID method. This will help users understand the purpose and usage of each method more easily.
For example:
// New creates a new session middleware func New(config ...Config) *Middleware // NewWithStore creates a new session middleware and returns both the middleware and the store func NewWithStore(config ...Config) (fiber.Handler, *Store) // Add descriptions for other methods...
418-444: Enhance custom types exampleThe example for registering custom types is helpful, but it could be improved by showing how to actually use the custom type in a session. Consider adding a route that demonstrates setting and getting a custom type in the session.
Here's an example of how you could enhance the custom types example:
app.Get("/set-user", func(c fiber.Ctx) error { sess := session.FromContext(c) if sess == nil { return c.SendStatus(fiber.StatusInternalServerError) } user := User{Name: "John Doe", Age: 30} sess.Set("user", user) return c.SendString("User set in session") }) app.Get("/get-user", func(c fiber.Ctx) error { sess := session.FromContext(c) if sess == nil { return c.SendStatus(fiber.StatusInternalServerError) } user, ok := sess.Get("user").(User) if !ok { return c.SendString("User not found in session") } return c.JSON(user) })
445-482: Align Config table with Default Config codeTo improve consistency and clarity, consider aligning the order of fields in the Config table with the order in the Default Config code. This will make it easier for users to compare the default values with the available options.
Additionally, ensure that all fields in the Default Config are also present in the Config table. For example, the
Storefield is present in the Default Config but not in the Config table.🧰 Tools

12-95: Approve changes to Config struct with a minor suggestionThe changes to the
Configstruct are well-documented and provide improved flexibility for session management. The addition ofNext,ErrorHandler,IdleTimeout, andAbsoluteTimeoutfields enhances the middleware's capabilities.Consider adding a brief example in the documentation for the
Nextfield to illustrate its usage, similar to how you've documented theDefaultErrorHandler. This would help developers understand how to implement conditional middleware skipping.
Line range hint
133-187: Approve changes to configDefault with a suggestionThe updates to
configDefaultimprove configuration validation and error handling. The addition of checks forIdleTimeoutandAbsoluteTimeoutensures more robust session management.Consider wrapping the panic calls with a custom function to allow for easier testing and potential future enhancements in error handling. For example:
func configError(message string) { panic("[session] " + message) } // Usage if len(selectors) != numSelectors { configError("KeyLookup must be in the format '<source>:<name>'") }This approach maintains the current behavior while providing flexibility for future modifications.

117-131: LGTM with suggestion: DefaultErrorHandler implementationThe
DefaultErrorHandlerfunction provides a good basic error handling mechanism. However, consider enhancing the error logging to include more context, such as the request ID or path.Example improvement:
func DefaultErrorHandler(c fiber.Ctx, err error) { log.Errorf("session error on %s: %v", c.Path(), err) if sendErr := c.SendStatus(fiber.StatusInternalServerError); sendErr != nil { log.Errorf("session: failed to send error status: %v", sendErr) } }This change would provide more detailed logging, making it easier to trace and debug issues.

8-8: LGTM: Import statement additionThe addition of the
logpackage fromgithub.com/gofiber/fiber/v3/logis appropriate for the new error handling functionality introduced in this file.
19-21: LGTM: Addition of Next functionThe
Nextfunction allows for conditional skipping of the middleware, providing more flexibility in request handling.
28-31: LGTM: Addition of ErrorHandlerThe
ErrorHandlerfunction allows for custom error handling, improving the middleware's flexibility and error management capabilities.
66-71: LGTM: Replacement of Expiration with IdleTimeoutThe
IdleTimeoutfield replaces the previousExpirationfield, providing a clearer semantic meaning for session inactivity expiration. The default value and documentation are appropriate.
73-78: LGTM: Addition of AbsoluteTimeoutThe
AbsoluteTimeoutfield adds the ability to set a maximum duration for a session, independent of activity. This enhances session management capabilities.
155-157: LGTM: IdleTimeout handlingThe check for
IdleTimeoutensures that a valid duration is always set, defaulting to theConfigDefaultvalue if necessary.
158-161: LGTM: AbsoluteTimeout validationThe check ensuring that
AbsoluteTimeoutis greater than or equal toIdleTimeoutis crucial for maintaining logical session timeout behavior.🧰 Tools

164-225: Consider optimizing test setup.The test cases are comprehensive and well-structured. However, consider moving the
fiber.New()initialization outside the subtest to improve test efficiency:func Test_Store_GetByID(t *testing.T) { t.Parallel() // Create a new store store := NewStore() + app := fiber.New() t.Run("valid session ID", func(t *testing.T) { t.Parallel() - app := fiber.New() // Create a new session ctx := app.AcquireCtx(&fasthttp.RequestCtx{}) // ... rest of the test }) }

23-104: LGTM! Consistent initialization and proper resource cleanup.The changes correctly:
- Use the new
NewStore()initialization consistently- Add proper context cleanup with
defer app.ReleaseCtx(ctx)addressing previous resource leak concerns
125-146: LGTM! Well-structured test for middleware conflict.The test properly verifies the behavior when a session is already loaded by middleware.
148-162: LGTM! Comprehensive test coverage for delete operations.The test cases properly verify:
- Error handling for empty session IDs
- Graceful handling of non-existing sessions
