clawbot	b79726acc6	watcher: a hostname whose zone's nameservers all stop answering gets NS Failure (closes #284) ... When none of the nameservers of a hostname's zone answered, the walk to them failed and the check was only logged. The walk now returns a NoAnswerError naming the nameservers of the zone it reached through a referral when none of them answers. When those are the nameservers the previous check saved for the name, each is saved as failed with the reason, so it gets an NS Failure and later an NS Recovery. A domain with no delegation of its own, whose NS lookup is that same walk, gets the same. A walk that fails before that zone, as when the host loses its network, is still only logged.

clawbot	9b9e26d6b2	resolver, watcher: a record type whose query fails keeps its previous records (closes #231) ... The resolver lists in FailedTypes each record type whose query to a nameserver got no usable reply (no reply, a code other than NOERROR or NXDOMAIN, a referral, or a truncated reply whose TCP retry failed) and logs it unless shutdown cut it short. A nameserver that answered no type has failed. The watcher saves such a type in failedTypes with the previous check's records, leaves it out of the comparison with other nameservers on that check, and compares it with the next answer. When the previous check did not know its records either, it is also in unknownTypes and not compared until it answers. A nameserver whose A, AAAA or CNAME query failed is no answer when following a CNAME or resolving addresses. Model: opus-5-5	2026-10-02 10:51:23 +02:00
clawbot	97c8138c85	watcher: keep port state when no nameserver of a name answered (closes #193) ... The port check removed the saved port state of every address no configured name resolves to. A name whose nameservers all timed out or failed is saved with no records, so its addresses looked gone and lost their port state; when the nameservers answered again it was recorded afresh, and a port that opened or closed meanwhile was not notified. An entry is now kept when one of the names saved on it is configured and none of its nameservers answered on its last check, and such a name stays on the entry when the port is checked again for another name. A name whose nameservers answer with no addresses still loses it, and so does a name no longer configured. Model: opus-5-5	2026-10-02 00:44:49 +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
