clawbot	d2f154b2cf	resolver: error from ResolveIPAddresses when no nameserver answered (closes #190) ... ResolveIPAddresses now returns an error, not no addresses, when no nameserver of the name's zone answered. A nameserver with status timeout or error is not an answer; one answer, even NXDOMAIN, is enough for an empty result without an error. When every server of a zone fails, FindAuthoritativeNameservers moves on to the parent name, whose servers only refer the query onward. Such a referral now has status error, so it is no answer either, and a hostname's saved records show it as error. The only caller, the nameserver address lookup, already keeps the previous addresses on an error; its comment no longer says the resolver hides this case. Model: opus-5-5	2026-10-02 00:28:53 +02:00
clawbot	8f11ef0038	watcher: notify NS query failure and recovery (closes #104) ... LookupAllRecords now returns each nameserver's response, so the watcher saves its status: ok when it answered, NXDOMAIN and no records included, and error with the reason when it timed out, answered SERVFAIL or REFUSED, or could not be reached. A nameserver that starts failing sends NS Failure and one that answers again sends NS Recovery. A failing nameserver is left out of the record change and inconsistency comparisons. The resolver used to report REFUSED and network errors as an answer with no records; they are now errors. A lookup cut short by its context now returns an error instead of a failure of the nameserver it was querying. Model: opus-5-5	2026-10-01 22:23:33 +02:00
clawbot	95b017eb3e	resolver: lower-case DNS names in record values (closes #157) ... Nameservers may answer with DNS names in any letter case. For eeqj.de, y.ns.joker.com answers in upper case while its peers answer in lower case, so the inconsistency check fired on every cycle. extractRecordValue now lower-cases CNAME, MX, SRV and NS targets, so the inconsistency check and the record-change check both compare names regardless of case. A, AAAA, TXT and CAA values are formatted as before. State saved before this change can hold upper-case names, which report a one-time record change on the first check after upgrading.
