dnsimple/dnstest

This system is a DNS server implementation written in Erlang, focused on protocol compliance and testing. It manages DNS zone data and supports advanced features such as DNSSEC and ALIAS records. The codebase includes a dedicated test suite that validates behavior against RFC standards, specifically covering empty non-terminal nodes and wildcard resolution logic.

The \priv\ directory now includes new JSON files defining DNS zone data for \example.com\, \minimal-dnssec.com\, \test.com\, and \wtest.com\, alongside Ruby scripts (\host\_record\_generator.rb\, \toomuchinfo\_record\_generator.rb\) to programmatically generate test records. These files provide the underlying data structures for internal testing and specification validation, supporting features such as DNSSEC, ALIAS records, and various record types.

The DNS server conformance testing application has been renamed from \erldns\_test\ to \dnstest\. This change updates the application source, module names, and internal dependencies (such as the test harness and metrics modules) to reflect the new identifier, while also migrating the logging implementation from \lager\ to the standard \logger\ library.

src · high confidence

Added new test suites in \src/tests/ent\_specs.erl\ and \src/tests/wildcard\_specs.erl\ to verify DNS server compliance with RFC 4592. The ENT tests validate that queries to empty non-terminal nodes correctly return SOA records in the authority section, including handling of DNSSEC-signed responses (RRSIG/NSEC) and ensuring NXNAME is not incorrectly set in NSEC bitmaps. The wildcard tests cover scenarios such as wildcard bounding by ENTs, interactions between CNAMEs and wildcards at the zone apex, and validation of long CNAME chains involving wildcards.

The project has migrated from the legacy rebar build tool to rebar3, updating the build configuration to use modern plugins (rebar3\_hex, rebar3\_ex\_doc, rebar3\_lint, erlfmt) and stricter compiler warnings. This change includes switching the primary DNS dependency from a git-hosted 'dns' package to the hex package 'dns\_erlang' (version 5.0.18), removing the 'lager' dependency in favor of standard Erlang logging, and updating the test runner script to use rebar3 for compilation and configuration loading.
