CURRENT STATUS

Description

Split the existing Ctx API into two separate APIs for Requests and Responses. Having distinct APIs for Request and Response types will allow developers to more easily write self-documenting code by avoiding ambiguous methods such as Ctx.Cookie and Ctx.Cookies. Much of the existing Ctx API simply calls the corresponding Req or Res API. For example, Ctx.Get calls Request.Get and Ctx.Set calls Response.Set.

Because Express defines only res and req APIs with no context API, this change will make it easier to manage Fiber's adherence to Express's APIs. In addition, it will allow us to avoid needing to create certain one-off methods. For example, Ctx.GetRespHeader can now become Ctx.Res().Get

Although the majority of the Ctx API is unchanged, Ctx.Request and Ctx.Response have been removed in favor of Ctx.Req and Ctx.Res. Now, instead of a raw fasthttp.Request or fasthttp.Response, we return fiber.Request and fiber.Response objects, which implement their respective APIs. As such, this is a breaking change for users who access Ctx.Request and Ctx.Response direct.

Inspired by Koa and fasthttp, both of which have individual request/response objects and a single context object whose methods are simply aliases for corresponding methods on the req/res APIs.

Deprecation:

  • Ctx.GetRespHeader is replaced by Ctx.Res().Get

@nickajacks1 Just so you are aware, the tests are very unstable/flaky right now in main. This is because we no longer retry failed tests multiple times on the CI. This is being fixing in #2892

Hi @gofiber/maintainers

Sorry this is taking so long.
I've reached the first major milestone - the Request API is fully moved over to the Request type.
I'd like to get a health check - does the overall direction still seem OK? If so, I suspect that moving the Response API over will be comparatively quick.
None of the unit tests have been moved over. IMO that's quite a bit of work and shouldn't hold up v3 since it's not public facing and can be done at any time.

Even though Express has Locals as part of the res API, I feel like it makes more sense to keep it as part of Ctx since it doesn't inherently have anything to do with the response (or request for that matter). I'm going to leave in Ctx for now.

ok, sounds reasonable we can always adapt it later

Ok, the Response API is fully moved over.

Some remaining work:
I didn't move Redirect to the Response API yet. The Redirect API has some dependencies on DefaultCtx that requires more thought. Moving Redirect to Res won't break the API in any way, so we can take our time thinking about this.

Next week I'll start on either the docs or the interface part.

I was thinking, is it actually that useful to make Request and Response interfaces if Ctx is already an interface and can thus be expanded instead of Request/Response? If we say that custom extensions should just go through Ctx, that might simplify both the API and implementation a bit.
Thoughts @gofiber/maintainers ?

I am interested in learning more about the approach of expanding the Ctx interface for custom extensions, instead of introducing separate Request and Response interfaces. Could you please explain how this approach works and how it simplifies the API for developers?

In addition, can you help us by merging the changes added to the main branch, and updating your PR to use the new Bind() interface?

Thank you, great work so far, and I look forward to your reply!

I am interested in learning more about the approach of expanding the Ctx interface for custom extensions, instead of introducing separate Request and Response interfaces. Could you please explain how this approach works and how it simplifies the API for developers?

The two primary points I have in mind are:

  1. Any extension of behavior can already be handled by using a custom Ctx since the split implementation is at its core a kind of syntactic sugar. I have not been able to think of a use case for Req/Res interfaces that can't be handled with the Ctx interface.
  2. Since the Ctx and Request+Response APIs have overlap, it may be less clear to developers which they should implement. If they want to update SendString to tee out some logs, should they do it by making a custom Ctx or a custom Respose? I feel like having either Ctx or Request+Response be interfaces may be more straightforward (and I lean toward Ctx). This is more what I meant when I implied that having all three of Ctx, Request, and Response be interfaces could make the API more complex.

In addition, can you help us by merging the changes added to the main branch, and updating your PR to use the new Bind() interface?

ye. will also probably be able to mark the PR ready for review soon.

Marking as ready for review. If it is decided to make Request and Response interfaces, I will update the PR.
Regarding the docs, I think it might be better to get this in first and then write up the docs.

Out of diff range and nitpick comments (4)
middleware/etag/etag.go (1)

Line range hint 37-92: Ensure proper handling of weak ETags and canonical setting of ETag headers.

- if bytes.HasPrefix(clientEtag, weakPrefix) {
-   if bytes.Equal(clientEtag[2:], etag) || bytes.Equal(clientEtag[2:], etag[2:]) {
-     c.Context().ResetBody()
-     return c.SendStatus(fiber.StatusNotModified)
-   }
- }
- c.Context().Response.Header.SetCanonical(normalizedHeaderETag, etag)
+ if bytes.HasPrefix(clientEtag, weakPrefix) && (bytes.Equal(clientEtag[2:], etag) || bytes.Equal(clientEtag[2:], etag[2:])) {
+   c.Context().ResetBody()
+   return c.SendStatus(fiber.StatusNotModified)
+ } else {
+   c.Context().Response.Header.SetCanonical(normalizedHeaderETag, etag)
+ }

This change ensures that the ETag header is only set when necessary and improves the handling of weak ETags by consolidating the conditions into a clearer structure.

middleware/session/store.go (1)

Line range hint 108-126: Review the handling of session IDs and cookies to ensure security and performance.

- id = string(c.Context().Request.Header.Peek(s.sessionName))
- if len(id) > 0 {
-   return id
- }
+ if idBytes := c.Context().Request.Header.Peek(s.sessionName); len(idBytes) > 0 {
+   return utils.CopyString(string(idBytes))
+ }

This change ensures that the session ID is copied correctly, preventing potential issues related to slice reuse in Go, which can lead to subtle bugs and security vulnerabilities.

middleware/proxy/proxy_test.go (2)

Line range hint 147-147: Ensure TLS configuration specifies a minimum version.

- clientTLSConf := &tls.Config{InsecureSkipVerify: true} //nolint:gosec // We're in a test func, so this is fine
+ clientTLSConf := &tls.Config{InsecureSkipVerify: true, MinVersion: tls.VersionTLS13} //nolint:gosec // We're in a test func, so this is fine

Line range hint 314-314: Ensure TLS configuration specifies a minimum version.

- clientTLSConf := &tls.Config{InsecureSkipVerify: true} //nolint:gosec // We're in a test func, so this is fine

middleware/session/store_test.go (1)

Line range hint 28-58: Ensure consistent use of context for setting and getting session IDs.

The changes correctly utilize the new context-centric approach for setting and getting session IDs from cookies, headers, and URL queries. This aligns with the overall architectural changes in the framework.

middleware/idempotency/idempotency.go (1)

120-122: Ensure proper handling of response status codes and body in idempotency middleware.

The changes correctly handle the response status code and body, ensuring that they are properly managed and stored for idempotent operations. This aligns with best practices for idempotency in web applications.

middleware/logger/default_logger.go (1)

Line range hint 36-69: Review the use of context for retrieving response status codes in logging.

The changes correctly utilize the new context-centric approach for retrieving response status codes, ensuring that the logging functionality is consistent with the overall architectural changes in the framework.

middleware/adaptor/adaptor.go (1)

87-93: Ensure headers are correctly set and context is properly copied.

Verification successful

The CopyContextToFiberContext function uses reflection to dynamically handle and copy context fields from a generic context object to fasthttp.RequestCtx. It is designed to handle potentially unexported fields and sets user values based on the fields it iterates over. This implementation suggests a comprehensive approach to copying context, aligning with the expected behavior for proper context management in the HTTPMiddleware function.

210-210: Ensure custom ETag handling in test scenarios is correctly implemented.

middleware/filesystem/filesystem.go (1)

233-240: Ensure file serving and header setting are correctly implemented, including handling of GET and HEAD requests.

Verification successful

The verification process has successfully located the filesystem.go file and confirmed the implementation details related to setting the body stream and handling GET and HEAD requests. The code snippets provided from the search results clearly show the handling for both fiber.MethodGet and fiber.MethodHead:

  • For GET requests, the SetBodyStream method is used to set the body of the response with the file content and the specified content length.
  • For HEAD requests, the SkipBody property is set to true, which is consistent with the expected behavior where the body should not be sent but headers and status should be.

These findings align with the initial review comment that approved the implementation and requested verification of these specific functionalities. Therefore, the implementation is correct as per the review comment.

The verification confirms that the file serving and header setting in `filesystem.go` are implemented correctly for both GET and HEAD requests. The handling of the body stream and response headers aligns with the expected standards for these request methods.

- `middleware/filesystem/filesystem.go`: Correct implementation for setting the body stream and handling GET and HEAD requests.

197-197: Review the error handling logic for unmatched routes.

Verification successful

The expanded search has successfully located the error handling logic for unmatched routes in the router.go file. The results show two instances where NewError(StatusNotFound, "Cannot ...") is used, indicating that the error handling logic is indeed implemented for unmatched routes. Both instances are associated with comments that clarify the intent to return a 404 status when no matching route is found.

Given this information, it appears that the error handling logic for unmatched routes is both present and implemented in a manner consistent with good practices (i.e., providing clear error messages and handling cases where no routes match).

Final Response:

The error handling logic for unmatched routes in router.go is correctly implemented and robust. The code correctly generates a StatusNotFound error when no routes match the incoming request, which is a standard practice for handling such cases in web applications.

  • Location of the implementation:
    • router.go around lines where NewError(StatusNotFound, "Cannot ...") is called.

Tip

Codebase Verification

The review comment's concern about the robustness of the default tree path handling in router.go is valid. The code does not include explicit error handling or fallback mechanisms if the default tree path is also missing or invalid. This could potentially lead to runtime errors, especially since the code attempts to calculate the length of the tree and iterate over it without ensuring that the tree is properly initialized.

  • Location: router.go in the next function around the assignment tree = app.treeStack[c.req.methodINT][""].

    }

Given this context, the error handling around the SetBodyStream method is indirectly managed through the openFile function, which ensures that any errors encountered while opening the file are handled appropriately before the file is passed to SetBodyStream.

156-157: Ensure that the default media type is set correctly when the Accept header is missing.


414-414: Verify that the error handling for determining the absolute file path is robust.

Verification successful

The search results indicate that the error handling for determining the absolute file path using filepath.Abs is indeed present in response.go and other files. The specific pattern in response.go is:

if file, err = filepath.Abs(file); err != nil {
    return fmt.Errorf("failed to determine abs file path: %w", err)
}

This confirms that the error handling for determining the absolute file path is robust and follows the expected pattern of wrapping the error with a descriptive message.

Finished docs in time, so I added them to this PR after all.
I'd like some criticism on how I updated the docs. I took the approach of keeping everything on a single page and using subsections for Request and Response methods.

I'm not sure what the best way to document the whole "c.Send() is the same as c.Res().Send()" thing is. I basically just sprinkled both forms in the examples, but I wonder if that would be confusing to newcomers.
I put a big green Tip box at the top to highlight it:
chrome_8rQ4swzyeG
I didn't individually list the Ctx methods that simply call a Req/Res method since I felt that would get overly verbose.

I am interested in learning more about the approach of expanding the Ctx interface for custom extensions, instead of introducing separate Request and Response interfaces. Could you please explain how this approach works and how it simplifies the API for developers?

The two primary points I have in mind are:

  1. Any extension of behavior can already be handled by using a custom Ctx since the split implementation is at its core a kind of syntactic sugar. I have not been able to think of a use case for Req/Res interfaces that can't be handled with the Ctx interface.
  2. Since the Ctx and Request+Response APIs have overlap, it may be less clear to developers which they should implement. If they want to update SendString to tee out some logs, should they do it by making a custom Ctx or a custom Respose? I feel like having either Ctx or Request+Response be interfaces may be more straightforward (and I lean toward Ctx). This is more what I meant when I implied that having all three of Ctx, Request, and Response be interfaces could make the API more complex.

I'm not sure about making Req and Resp not an interface. We're still able to update Ctx methods but it won't affect response for example. And it may cause some confusions as well. For example, if i've updated SendString, it means i'll have different behaving resp and ctx methods

Yeah, and this would be a problem whether or not Response is an interface. If response is an interface and you only override Ctx.SendString, you still have different behavior between Response and Ctx. Gonna have to think about that one some more since we'll want to address that either way.

Changing the subject a little...If Ctx implements both Request and Response, there's a corner case trap developers might hit if both Request and Response share method signatures, such as Get:

printResponseContentType := func(r Response) {
	fmt.Println(r.Get("Content-Type"))
}
printResponseContentType(c) // this prints the request's header, not the response's

The only ways I've thought of to get around this so far are to explicitly add methods to Request and Response that Ctx does not implement so that Ctx does not implement those interfaces OR enforce that Request and Response do not have overlapping methods (which eliminates one of the benefits of splitting the APIs). I'll brainstorm for clean ways to deal with it, but feel free to spitball ideas.

RE: overriding a method in Ctx but not Req/Res, resulting in differing behavior between e.g., c.Get and c.Req().Get, I fear the only real options to prevent/mitigate this that I could come up with may be to

  • Establish a clear direction for how we want the usage of interfaces to go and provide a detailed guide for interface usage (which we should make anyway) that lists ways you can shoot yourself in the foot. This unfortunately still leaves the door open for people to not read the guide and still shoot themselves in the foot.
  • Do not provide aliases in Ctx, which seems heavy handed and unpopular.
  • Do not make Ctx an interface, which may not be an option at this stage.

I imagine the last two options are non-starters, so I will focus on the first.
If the user overrides the Req or Res method instead of the Ctx method, everything is hunky dory. If they override Ctx methods that are also provided by Res or Res, we hit the case where c.Get and c.Req().Get do different things. This means that the undesirable case is only avoidable by making Req and Res interfaces. A relatively safe rule of thumb is probably that users should prefer to override at the Req/Res level if possible, falling back to Ctx if the situation requires it.

Maybe it's better if we don't make Req and Resp an interface and add a guide about customization
