: Approved the introduction ofsync.Pool
for managingfasthttp.RequestCtx
instances.The use of
sync.Pool
is a good practice for reducing memory allocations and improving performance. Ensure thatfasthttp.RequestCtx
objects are properly reset before reuse to avoid any side effects.
169-173
: Approved the use ofctxPool
inhandlerFunc
for acquiring and releasingfasthash.RequestCtx
.The implementation correctly utilizes the pool to manage
fasthttp.RequestCtx
instances, which should help in reducing memory allocations and improving performance. Verify that contexts are correctly acquired and released.
191-191
: Approved the response conversion inhandlerFunc
.The conversion from
fasthttp.RequestCtx
tonet/http
response is implemented correctly. Verify that all headers and status codes are correctly transferred to ensure a seamless client experience.
137-137
: Verify error handling inhandlerFunc
.Ensure that errors during the request body copying are correctly handled and that appropriate HTTP error responses are sent to the client.
Also applies to: 152-152
Verification successful
The error handling in
handlerFunc
is correctly implemented.
- If an error occurs during the body copying process, an HTTP 500 error response is sent to the client.

is done efficiently.Verification successful
Verified the handling of HTTP headers and context in middleware.
The
HTTPMiddleware
function correctly handles the setting of HTTP method, URI, and headers from thehttp.Request
to thefiber.Ctx
, ensuring that headers are not unintentionally overwritten and context is copied efficiently.

: Impressive documentation on Adaptor middleware improvements.The documentation clearly outlines the significant performance improvements in the Adaptor middleware, including detailed metrics. This aligns well with the PR objectives and provides users with a clear understanding of the benefits.
- Execution Time: The improvements are consistently above 40%, which is a great enhancement.
- Memory Usage: The reductions are impressive, nearly 90% in most cases.
- Allocations: The reduction to 5 allocs/op from 16 is substantial.
This section is well-documented and provides valuable information to the users about the improvements. It's also good to see the detailed metrics for different payload sizes, which helps in understanding the scalability of the improvements.

: General Documentation Review: Comprehensive and InformativeOverall, the documentation is comprehensive and covers a wide range of changes and improvements in Fiber v3. The migration guides are detailed, providing users with clear instructions on how to adapt their existing applications to the new version. The use of caution labels in draft sections is a good practice, ensuring that users are aware these sections are not finalized.
Here are a few suggestions for improvement:
- Ensure all draft sections are completed before the final release to provide users with full information.
- Consider adding more examples where significant changes are introduced, especially in areas like the new routing and middleware registration methods, to help users better understand the new patterns.
The documentation effectively communicates the enhancements and changes, making it easier for users to transition to the new version.
