<span></span><br>
<span>Dear all,</span><br>
<span></span><br>
<span>We have a new release, version 0.1.5 of our getdns API implementation.</span><br>
<span></span><br>
<span>This release includes the features from the API that affect hop-by-hop</span><br>
<span>communication and apply to stub resolution mode. The</span><br>
<span>"add_opt_parameters" extension from section 3.3 of the spec and all</span><br>
<span>getdns_context_set_edns_* functions from Section 8.8 have are now</span><br>
<span>implemented. The GETDNS_TRANSPORT_TCP_ONLY_KEEP_CONNECTIONS_OPEN</span><br>
<span>transport mode is also implemented with this release. IPv6 link-local</span><br>
<span>with scope_id upstreams are now supported, both in /etc/resolv.conf as</span><br>
<span>via getdns_context_set_upstream_recursive_servers().</span><br>
<span></span><br>
<span>In addition, TCP Fast open is available as an optional feature (linux</span><br>
<span>only). This mechanism enables data exchange during TCP’s initial</span><br>
<span>handshake and in doing so it decreases application network latency by</span><br>
<span>one full round-trip time.</span><br>
<span></span><br>
<span>To enable these features we have done a major internal rework. Before,</span><br>
<span>we used libunbound for both stub and recursive mode, but to get the</span><br>
<span>amount of control needed for the hop-by-hop communication features we</span><br>
<span>had to implement stub resolution independently. For this task we also</span><br>
<span>needed to review and refine our extensible event loop mechanism so it is</span><br>
<span>able to handle events for multiple simultaneous connections. (This was</span><br>
<span>handled internally by libunbound before)</span><br>
<span></span><br>
<span>As a consequence, this release is binary incompatible with respect to</span><br>
<span>the extensible event loop mechanism. The getdns_context_fd() function</span><br>
<span>that facilitated asynchronous processing based on select is no longer</span><br>
<span>available. Instead, getdns_context_run() should be used to perform</span><br>
<span>blocking asynchronous processing. The getdns_context_process_async()</span><br>
<span>and getdns_context_get_num_pending_requests() functions remain for</span><br>
<span>asynchronous processing in non-blocking fashion.</span><br>
<span></span><br>
<span>Besides our own three event loop extensions shipped alongside the</span><br>
<span>library (for libevent, libev and libuv) we are aware of only one</span><br>
<span>software package affected by this: the nodejs bindings. A new release</span><br>
<span>of the nodejs bindings fitting this release will follow shortly.</span><br>
<span></span><br>
<span>The internal rework has many improvements as a consequence. Many</span><br>
<span>implementation details that previously had specific code paths for the</span><br>
<span>different modus operandi (i.e. sync/recursive, sync/stub,</span><br>
<span>async/recursive and async stub) could be merged, resulting in a more</span><br>
<span>consistent and easier to maintain code base. Consequences can already</span><br>
<span>be seen in the simultaneous querying for IPv4 and IPv6 addresses and the</span><br>
<span>more consistent handling of name spaces, plus the possibility to alter</span><br>
<span>name space evaluation order even after a context has been used to sent</span><br>
<span>out a query.</span><br>
<span></span><br>
<span>Note that stub resolution will still use libunbound if any of the DNSSEC</span><br>
<span>extensions are into play. Performing stub validation independently from</span><br>
<span>libunbound is on the road map for the next release.</span><br>
<span></span><br>
<span>Besides these features, many bugs have been fixed with this release.</span><br>

<span>ChangeLog</span><br>
<span>=========</span><br>
<span>* 2014-10-31: Version 0.1.5</span><br>
<span> * Unit tests for transport settings</span><br>
<span> * Fix: adhere to set maximum UDP payload size</span><br>
<span> * API change: when no maximum UDP payload size is set, outgoing</span><br>
<span> values will adhere to the suggestions in RFC 6891 and may follow</span><br>
<span> a scheme that uses multiple values to maximize receptivity.</span><br>
<span> * Stub mode use 1232 maximum UDP payload size when connecting to an</span><br>
<span> IPv6 upstreams and 1432 with an IPv4 upstream.</span><br>
<span> * Evaluate namespaces (or not) on a per query basis</span><br>
<span> * GETDNS_NAMESPACE_LOCALNAMES namespace now gives just_address_answers</span><br>
<span> only and does not mimic a DNS packet answer anymore</span><br>
<span> * The add_opt_parameters extension</span><br>
<span> * IPv6 scope_id support with link-local addresses. Both with parsing</span><br>
<span> /etc/resolv.conf and by providing them explicitly via</span><br>
<span> getdns_context_set_upstream_recursive_servers</span><br>
<span> * Query for A and AAAA simultaneously with return_both_v4_and_v6</span><br>
<span> * GETDNS_TRANSPORT_TCP_ONLY_KEEP_CONNECTIONS_OPEN DNS transport</span><br>
<span> * Fix: Answers without RRs in query secion (i.e. REFUSED)</span><br>
<span> * Fix: Return empty response dict on timeout in async mode too</span><br>
<span> * Move spec examples to spec subdirectory</span><br>
<span> * Fix issue#76: Setting UDP Payload size below 512 should not error</span><br>
<span> * Fix: Include OPT RR in response dict always (even without options)</span><br>
<span> * TCP Fast open support (linux only).</span><br>
<span> Enable with the --enable-tcp-fastopen configure option</span><br>
<span> * Bump library version because of binary API change</span><br>
