CHANGES.md.html

v0.10.0 (2017-11-05)

  • Increase entropy by randomising UDP source ports and transaction ids

  • Add missing build dependency on ppx_sexp_conv

v0.9.0 (2017-07-24)

  • Port to MirageOS 3.0 (#70, @samoht)

v0.8.4 (2017-03-28)

  • if we fail to resolver a name, timeout rather than sending NXDomain

  • switch to jbuilder

  • split into 2 opam packages: dns-forward and dns-forward-lwt-unix

v0.8.3 (2017-03-12)

  • if we fail to resolve a name, return NXDomain rather than simply timing out

  • avoid logging per-request if no servers are configured at all

v0.8.2 (2017-03-10)

  • add global configuration option assume-offline-after-drops which tells the resolver to consider an upstream offline if it fails to respond to this number of queries in a row

  • when a server is offline we continue to send queries to it, but we don't wait for responses. This prevents a bad server making us wait until timeout on every request.

  • we use Lwt.nchoose_split to wait for equal-priority results at once: this avoids waiting for requests in arbitrary list order (previously we used Lwt.fold_left_s)

  • we resend requests every 1s even if the timeout is longer

v0.8.1 (2017-02-06)

  • always set the Recursion Available bit from cached responses

v0.8.0 (2017-01-11)

  • send all requests in parallel, process results in order

  • don't cancel listening threads when the first response arrives, so we can cache all server responses

  • servers with zones are now included in general searches

  • prioritise successful responses over failures

v0.7.2 (2016-11-18)

  • Fix build with OCaml 4.04

v0.7.1 (2016-11-18)

  • Remove some spammy debug messages

v0.7.0 (2016-11-15)

  • Fix race where a timeout could mark an id as free and an old answer to the wrong question could be confused with the answer we're expecting

  • Minimise amount of transaction id re-use

v0.6.0 (2016-11-14)

  • If a single server fails, don't cancel all other resolution attempts.

v0.5.1 (2016-11-11)

  • Silence some of the spammy logging

v0.5.0 (2016-11-11)

  • Cache and local names callback: return packets of type "response" rather than "request"

v0.4.0 (2016-11-03)

  • Cache results for up to the TTL

v0.3.0 (2016-11-03)

  • Require lwt >= 2.6.0 for Lwt_results

  • Remove per-request timeout value: clients should cancel thread

  • Add per-server timeout value

  • Add notion of server ordering

v0.2.0 (2016-10-26)

  • Remove getclientname from Flow.Client

  • Make the addresses in the message_cb functions optional

v0.1.0 (2016-10-25)

  • Initial version
