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

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