* github.com/miekg/dns * Greatly simplify the logic for handling serial numbers. Related code was all over the place. Now it is abstracted into one testable method makeSoa. This simplifies code in many other places. * Update docs/_providers/bind.md: Edit old text. Add SOA description. * SOA records are now treated like any other record internally. You still can't specify them in dnsconfig.js, but that's by design. * The URL for issue 491 was wrong in many places * BIND: Clarify GENERATE_ZONEFILE message

// PopulateFromString populates a RecordConfig given a type and string.

// Many providers give all the parameters of a resource record in one big

// string (all the parameters of an MX, SRV, CAA, etc). Rather than have

// each provider rewrite this code many times, here's a helper function to use.

// Therefore the typical calling sequence is:
|

// if err := rc.PopulateFromString(rtype, value, origin); err != nil {
|

// panic(fmt.Errorf("unparsable record received from provider: %w", err))
