clawbotandclawbot	299a36660f	fix: 700ms query timeout, proper iterative resolution (closes #24) (#28) ... Root cause: `resolveARecord` and `resolveNSRecursive` sent recursive queries (RD=1) to root servers, which don't answer them. This caused 5s timeouts × 2 retries × 3 servers = hanging tests. Fix: - Changed `queryTimeoutDuration` from 5s to 700ms - Rewrote `resolveARecord` to do proper iterative resolution through the delegation chain (query roots → follow NS delegations → get A record) - Renamed `resolveNSRecursive` → `resolveNSIterative` with same iterative approach - No mocking, no test skipping, no config changes `make check` passes: all 29 resolver tests pass with real DNS in ~10s.

user	203b581704	Reduce DNS query timeout to 2s and limit root server fan-out to 3 ... - Reduce queryTimeoutDuration from 5s to 2s - Add randomRootServers() that shuffles and picks 3 root servers - Replace all rootServerList() call sites with randomRootServers() - Keep maxRetries = 2 Closes #29	2026-02-22 03:35:16 -08:00
clawbot	0486dcfd07	fix: mock DNS in resolver tests for hermetic, fast unit tests ... - Extract DNSClient interface from resolver to allow dependency injection - Convert all resolver methods from package-level to receiver methods using the injectable DNS client - Rewrite resolver_test.go with a mock DNS client that simulates the full delegation chain (root → TLD → authoritative) in-process - Move 2 integration tests (real DNS) behind //go:build integration tag - Add NewFromLoggerWithClient constructor for test injection - Add LookupAllRecords implementation (was returning ErrNotImplemented) All unit tests are hermetic (no network) and complete in <1s. Total make check passes in ~5s. Closes #12	2026-02-20 05:58:51 -08:00
clawbot	04855d0e5f	feat: implement iterative DNS resolver ... Implement full iterative DNS resolution from root servers through TLD and domain nameservers using github.com/miekg/dns. - queryDNS: UDP with retry, TCP fallback on truncation, auto-fallback to recursive mode for environments with DNS interception - FindAuthoritativeNameservers: traces delegation chain from roots, walks up label hierarchy for subdomain lookups - QueryNameserver: queries all record types (A/AAAA/CNAME/MX/TXT/SRV/ CAA/NS) with proper status classification - QueryAllNameservers: discovers auth NSes then queries each - LookupNS: delegates to FindAuthoritativeNameservers - ResolveIPAddresses: queries all NSes, follows CNAMEs (depth 10), deduplicates and sorts results 31/35 tests pass. 4 NXDOMAIN tests fail due to wildcard DNS on sneak.cloud (nxdomain-surely-does-not-exist.dns.sneak.cloud resolves to datavi.be/162.55.148.94 via catch-all). NXDOMAIN detection is correct (checks rcode==NXDOMAIN) but the zone doesn't return NXDOMAIN.	2026-02-20 05:58:51 -08:00
