Walkthrough

Adds new binding flow (Bind.All with precedence/merge), extends logging API, introduces context-aware storage methods and memory GC/value handling, adds new router API name RebuildTree, new ctx constructor, test TLS helper, request pair sorter, idempotency helpers and memory lock, envvar middleware handler/type, heap methods for cache, and multiple doc/comment updates plus minor new public types.

Changes

Cohort / File(s) Summary
Binding flow and helpers
bind.go
Adds skipValidation field and new All(out) method to bind from URI → Body (conditional) → Query → Headers → Cookies with precedence/merge and final validation.
Binder utilities and stubs
binder/binder.go, binder/cbor.go, binder/msgpack.go, binder/header.go, binder/uri.go, binder/mapping.go

Internal storage and memory
internal/memory/memory.go, internal/storage/memory/memory.go
Internal memory item now stores value and expiration; starts timestamp updater and 1s GC loop. Public storage adds context-aware Get/Set/Delete/Reset, treats missing/expired as nil, and Keys filters expired.
Idempotency middleware
middleware/idempotency/idempotency.go, middleware/idempotency/locker.go
Adds IsFromCache/WasPutToCache helpers; implements per-key in-memory locking with NewMemoryLock and Lock/Unlock, including reference counting and cleanup.
EnvVar middleware
middleware/envvar/envvar.go
Adds EnvVar struct and New(...) handler that returns selected environment variables as JSON for GET/HEAD.
Cache heap
middleware/cache/heap.go
Implements heap.Interface: Len/Less/Swap/Push/Pop on indexedHeap and maintains indices map.
Limiter middleware API
middleware/limiter/limiter.go, middleware/limiter/limiter_fixed.go, middleware/limiter/limiter_sliding.go

Adds Cookie struct; adds Constraint struct for route segment validation; exports UnsupportedValueError alias; refines comments on Range and DefaultReq.
Client request sorting
client/request.go
Adds sort.Interface (Len/Swap/Less) to pair for key-sorted alignment of keys/values.
TLS test helper
internal/tlstest/tls.go
Adds GetTLSConfigs() to generate CA, server certs, and server/client tls.Config.
Logger middleware utilities
middleware/logger/config.go, middleware/logger/utils.go

Poem

I thump my paws on freshly tilled code,
Binding crumbs from every road;
Logs now chatter in many tongues,
Locks stand guard with careful lungs.
Memory sweeps, the heap keeps time—
Rebuilt routes hop back in line.
Carrot-shaped certs? Tastes sublime! 🥕✨

Pre-merge checks and finishing touches

❌ Failed checks (1 warning)
Check name Status Explanation Resolution
Description Check ⚠️ Warning The PR description is a single-line summary ("Document all exported elements in the code base") and does not follow the repository's required template. It omits the detailed Description section, a "Fixes #" reference, the "Changes introduced" list (including affected files and any breaking changes), the Type of change selections, and the required checklist items such as tests, docs, benchmarks, and migration guidance. Because these template items are missing, the description is insufficient for proper review and release planning. Please expand the PR description to fully populate the repository template: add a clear purpose and motivation, enumerate concrete changes and affected files (explicitly call out public API additions or renames such as BuildTree→RebuildTree), include "Fixes #…" if relevant, mark the appropriate Type of change boxes, and fill the checklist with tests, documentation updates, and any migration steps; if API changes are accidental, separate them into a distinct PR and keep this one documentation-only to simplify review.
✅ Passed checks (2 passed)
Check name Status Explanation
Title Check ✅ Passed The title "📒 docs: Ensure all exported elements are documented" concisely describes the PR's stated objective to document exported symbols and is related to many changes in the diff. However, the changeset also contains several non-documentation public API changes (new exported functions/types and a renamed public method BuildTree→RebuildTree) that the title does not surface. Because it accurately reflects the primary intent but omits notable API additions/renames, it may under-communicate the full scope to reviewers.

Code Review

This pull request significantly improves the documentation across the codebase by adding and clarifying comments for many exported helpers, types, and functions. The changes make the code easier to understand and follow Go's documentation conventions. The updates to comments for TLSHandler, Group, Registering, and various storage helpers are particularly helpful. I have one minor suggestion for improving the wording of a comment in register.go for better clarity. Overall, this is a great contribution to the project's maintainability.

24-38: Potential race condition in Lock method.

The lock counting logic has a race condition. Between Lines 33 (releasing l.mu) and 35 (acquiring lock.mu), another goroutine could potentially call Unlock on the same key, decrement the counter to 0, and delete the entry from the map. This would cause the current goroutine to hold a lock on a deleted entry.

Consider holding l.mu until after acquiring lock.mu:

 func (l *MemoryLock) Lock(key string) error {
 	l.mu.Lock()
 	lock, ok := l.keys[key]
 	if !ok {
 		lock = new(countedLock)
 		l.keys[key] = lock
 	}
 	lock.locked++
-	l.mu.Unlock()
 
 	lock.mu.Lock()
+	l.mu.Unlock()
 
 	return nil
 }

40-63: Race condition in Unlock method.

Similar to the Lock method, there's a race condition in the Unlock method. The counter check and deletion at Lines 54-59 should be done while still holding lock.mu to prevent race conditions with concurrent Lock calls.

Apply this fix to ensure thread safety:

 func (l *MemoryLock) Unlock(key string) error {
 	l.mu.Lock()
 	lock, ok := l.keys[key]
 	if !ok {
 		// This happens if we try to unlock an unknown key
 		l.mu.Unlock()
 		return nil
 	}
-	l.mu.Unlock()
-
-	lock.mu.Unlock()
-
-	l.mu.Lock()
 	lock.locked--
 	if lock.locked <= 0 {
 		// This happens if countedLock is used to Lock and Unlock the same number of times
 		// So, we can delete the key to prevent memory leak
 		delete(l.keys, key)
 	}
 	l.mu.Unlock()
+	lock.mu.Unlock()
 
 	return nil
 }
middleware/cache/heap.go (1)

51-56: Return the popped element before shortening the slice (fix runtime panic).

The current Pop truncates h.entries then evaluates h.entries[0:n][n-1], which will slice past the (new) len and panic. Capture the element first and then shorten the slice:

v := h.entries[n-1]
h.entries = h.entries[:n-1]
return v

♻️ Duplicate comments (1)
register.go (1)

27-28: LGTM! Documentation comment addresses previous feedback.

The updated documentation comment is clear and professional, describing that Registering provides route registration helpers for a specific path. This addresses the previous review comment about using more formal language.

🧹 Nitpick comments (7)
middleware/idempotency/locker.go (1)

13-16: Consider documenting the countedLock type.

While countedLock is unexported, adding a brief comment would help future maintainers understand its purpose as a reference-counted mutex.

+// countedLock is a reference-counted mutex that tracks the number of goroutines
+// waiting to acquire the lock.
 type countedLock struct {
 	mu     sync.Mutex
 	locked int
 }
middleware/envvar/envvar.go (2)

23-25: Consider adding documentation for the helper method.

While this is a private method, adding a brief comment would improve code maintainability and explain its purpose within the type.

+// set adds or updates an environment variable in the Vars map.
 func (envVar *EnvVar) set(key, val string) {
 	envVar.Vars[key] = val
 }

52-69: Consider adding documentation for the helper function.

The newEnvVar function contains important security logic (preventing accidental information disclosure) that would benefit from documentation explaining this behavior.

+// newEnvVar creates a new EnvVar instance populated with environment variables
+// based on the provided configuration. If no ExportVars are configured, returns
+// an empty map to prevent accidental information disclosure.
 func newEnvVar(cfg Config) *EnvVar {
 	vars := &EnvVar{Vars: make(map[string]string)}
internal/tlstest/tls.go (1)

52-55: Ignoring error returns from pem.Encode

While this is test code, silently discarding errors from pem.Encode could make debugging failures harder. Even in test utilities, it's good practice to handle errors.

Consider handling these errors:

-	_ = pem.Encode(&caPEM, &pem.Block{
+	if err := pem.Encode(&caPEM, &pem.Block{
 		Type:  "CERTIFICATE",
 		Bytes: caBytes,
-	})
+	}); err != nil {
+		return nil, nil, err
+	}
binder/binder.go (1)

76-83: Consider more descriptive panic message

The current panic message "failed to type-assert to T" doesn't provide enough context about what went wrong. Since T is a generic type parameter, the actual type information would be helpful for debugging.

 func GetFromThePool[T any](pool *sync.Pool) T {
 	binder, ok := pool.Get().(T)
 	if !ok {
-		panic(errors.New("failed to type-assert to T"))
+		panic(errors.New("binder: failed to type-assert pool value to expected type"))
 	}
 
 	return binder
 }
bind.go (2)

33-38: Document the unexported skipValidation field.

While skipValidation is unexported, it would be helpful to add an inline comment explaining its purpose for future maintainers.

 // Bind provides helper methods for binding request data to Go values.
 type Bind struct {
 	ctx            Ctx
 	dontHandleErrs bool
+	// skipValidation temporarily disables validation during multi-source binding
 	skipValidation bool
 }

373-391: Consider extracting zero value check logic.

The isZero function could potentially be moved to a utility package if this pattern is used elsewhere in the codebase. However, the current implementation is correct and efficient.
