WalkthroughThis pull request refactors error handling by introducing an object pooling mechanism for error instances (ZogErr). New methods and adjustments have been implemented to obtain, manage, and release these error objects efficiently via a dedicated pool. The changes span multiple files: adding a Changes

119-134:⚠️ Potential issueApply consistent error handling across all pool retrievals.
The same type assertion issue exists in IssueFromTest(), IssueFromCoerce(), and TestCtx.Issue().
Apply the same error handling pattern to all methods retrieving from the pool.
Also applies to: 136-145, 162-173

29-33: LGTM! Pool initialization looks good.The implementation follows sync.Pool best practices and maintains consistency with other pools in the file.
Consider pre-allocating the pool with an initial size hint if you have metrics on typical error rates:
var ZogIssuePool = sync.Pool{ New: func() any { + // Pre-allocate pool if typical error rates are known + // pool := make([]*ZogErr, 0, initialSize) return &ZogErr{} }, }utils.go (1)
125-131: Consider optimizing CollectList for large error collections.The current implementation could be optimized for large error collections.
Consider pre-allocating the slice and using a more efficient iteration:
func (i *issueHelpers) CollectList(issues ZogIssueList) { + if len(issues) == 0 { + return + } for _, err := range issues { if err, ok := err.(*p.ZogErr); ok { err.Free() } } }

99-103: LGTM! Efficient combination of sanitization and collection.The implementation properly combines sanitization and collection operations, reducing iterations over the error collections.

Add error handling for type assertion.
The type assertion from pool.Get() could panic if the pool returns an incorrect type.
Add error handling:
func (c *SchemaCtx) Issue() ZogIssue {
- e := ZogIssuePool.Get().(*ZogErr)
+ e, ok := ZogIssuePool.Get().(*ZogErr)
+ if !ok {
+ // Fallback to creating a new instance if pool returns wrong type
+ e = &ZogErr{}
+ }
e.EPath = c.Path.String()
e.Typ = c.DType
e.Val = c.Val
return e

Reset fields before returning to pool.
The Free() method should reset fields before returning the instance to the pool to prevent potential data leaks and ensure clean state for reuse.
Add field reset:
func (e *ZogErr) Free() {
+ // Reset fields to zero values before returning to pool
+ e.C = ""
+ e.EPath = ""
+ e.ParamsM = nil
+ e.Typ = ""
+ e.Val = nil
+ e.Msg = ""
+ e.Err = nil
ZogIssuePool.Put(e)
