3 people	6e9aefc47e	feat: complete Phase 4.1 error handling and robustness (HAN-385) ... - Fast mode cache isolation: TraverserConfig.Fast=false gives each referral its own independent InfoCache with no cross-branch glue inheritance; Fast=true (default) retains the shared root cache so earlier branch discoveries are reused - Wire cfg.Fast from CLI config into TraverserConfig in main.go - IDN/Punycode: NewReferral now converts unicode domain labels to their ACE/punycode form via golang.org/x/net/idna before querying, with a graceful fallback when conversion fails - DNSSEC: hasFinalAnswer() now skips RRSIG records alongside CNAME so a signed referral does not prevent CNAME following - Tests: DNSSEC RRSIG does not block CNAME follow, fast/non-fast cache isolation, 12-NS referral, IDN conversion, wildcard answer, long CNAME chain depth limit, partial branch failure with graceful degradation Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: multica-agent <github@multica.ai>	2026-06-08 03:22:21 +10:00
3 people	368f200d23	Phase 4.1: Error handling, edge cases, and robustness ... - Exponential backoff retry logic (100ms, 200ms, 400ms... capped at 2s) replacing fixed 100ms delay between retries - Explicit REFUSED and NOTIMP response types (RespREFUSED, RespNOTIMPL) surfaced as terminal results with user-visible messages - CNAME loop detection: walking the ancestor referral chain before following a CNAME prevents infinite recursion; produces RespCNAMELoop - DNAME record support: synthesize CNAME target from DNAME mapping when the server omits the RFC 6672 synthesized CNAME record - ErrorMessage field on Response for surfacing error details to users - Fix resolveGlueViaSystem timeout bug: deadline.Sub(deadline) was always 0; replaced with time.Until(deadline) - DNAME records excluded from hasFinalAnswer so DNAME-only responses are correctly classified as RespCNAMEFollow - Text and JSON output updated with labels for all new response types - Tests: CNAME loop (2-step and direct), REFUSED, NOTIMP, graceful degradation (partial and total server failure), DNAME synthesis, IsNameInChain, backoffDelay, ResponseClassification strings Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: multica-agent <github@multica.ai>	2026-06-08 03:11:46 +10:00
3 people	8e7beacc22	fix: address code review issues on PR #9 ... - gofmt main.go to fix tab indentation in main() body - stats.go ComputeSummary: return nil when Answers and ByType are empty - dns/types.go: remove duplicate ParseQueryType (dead code) - formatter.go: log hook errors to stderr when Debug > 0; add Debug to Config - text.go referralID: remove redundant depth==0 branch - text.go writeServers: remove version lookup placeholder string Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: multica-agent <github@multica.ai>	2026-06-08 02:32:58 +10:00
