Reuse fixed-path and Allow-header buffers so redirect and OPTIONS handling stop rebuilding temporary data on every request. Cache fallback chains and add regression coverage for redirect, 404, 405, and Allow behavior to keep the faster miss paths stable.
Make Context keys lazy so requests that never call Set stop allocating on reset. Reuse stable 404 and 405 handlers and add focused benchmarks so ServeHTTP miss paths stay measurable.
- FileText: now respects the provided status code instead of defaulting to 200 OK
- Request body limits: prepareRequestBody() is now only called when MaxRequestBodySize > 0
- ShouldBindJSON, ShouldBindWANF, ShouldBindGOB, ShouldBindForm, GetReqBody, PostForm
all now use the original c.Request.Body path when no limit is configured
- maxBytesReader: fixed exact-limit boundary case where body size == limit was
incorrectly rejected
- Added regression tests for FileText status codes and body limit behavior
All existing tests pass, and new tests verify the corrected behavior.
- Remove fallback to HTML() on template rendering failure
- Return 500 error without writing any content on error
- Only fallback to HTML() when renderer is nil or unsupported type
- Prevents multiple response writes
Reduce code duplication by calling c.HTML() for fallback cases:
- When template rendering fails
- When HTMLRender is not configured
- When HTMLRender is not a *template.Template
This ensures consistent behavior between HTMLBuf and HTML methods.
Add buffered rendering methods that encode to a buffer first, then
write the response. This allows returning a proper 500 status code
if encoding fails, unlike the streaming variants which must write
the status code before encoding (an inherent HTTP constraint).
New methods:
- JSONBuf(code int, obj any)
- GOBBuf(code int, obj any)
- WANFBuf(code int, obj any)
- HTMLBuf(code int, name string, obj any)
Trade-off: one extra memory allocation per call in exchange for
correct error status codes on encoding failure.
- Implement ShouldBind with support for JSON, Form, WANF, and GOB formats
- Add ShouldBindForm, ShouldBindGOB, and helper functions for form binding
- Use fmt.Appendf instead of fmt.Sprintf for better performance
- Replace interface{} with any for modern Go style
- Use maps.Copy for cleaner header copying
- Update strings.SplitSeq to use range over strings.Seq
- Remove deprecated placeholder comments and add proper implementations
- Fix reflect.Pointer usage for Go 1.22+ compatibility
