It reads each nameserver's status as the lookup already sets it; one answer, even NXDOMAIN, is enough for an empty result without an error.

resolver: error from ResolveIPAddresses when no nameserver answered (closes #190 )

check / check (push) Failing after 2m25s

Details

ResolveIPAddresses now returns an error wrapping ErrNoNameserverAnswered
when every nameserver of the name's zone timed out or failed, instead of
no addresses and no error. It reads each nameserver's status as the
lookup already sets it; one answer, even NXDOMAIN, is enough for an
empty result without an 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.

watcher: notify NS query failure and recovery (closes #104 )

check / check (push) Successful in 1m31s

Details

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.

resolver: lower-case DNS names in record values (closes #157 )

check / check (push) Successful in 58s

Details

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.
