+ By default the logging output stream is now flushed after each write.

+ IN if not set. This also adds better checks on the name and class

- The <command>b10-zonemgr</command> process is started by
- <command>bind10</command>.
- It keeps track of SOA refresh, retry, and expire timers
- and other details for BIND 10 to perform as a slave.
- When the <command>b10-auth</command> authoritative DNS server
- receives a NOTIFY message, <command>b10-zonemgr</command>
- may tell <command>b10-xfrin</command> to do a refresh
- to start an inbound zone transfer.
- The secondary manager resets its counters when a new zone is
- transferred in.

- <note><simpara>
- Access control (such as allowing notifies) is not yet provided.
- The primary/secondary service is not yet complete.

+Feature: IXFR out
+ Tests for IXFR-out, specific for BIND 10 behaviour.
+ These are (part of) the tests as described on
+ http://bind10.isc.org/wiki/IxfrSystemTests
+
+ # A lot of these tests test specific UDP behaviour.
+ #
+ # Where possible, we use the TCP equivalent. Some of the behaviour
+ # tested is UDP-specific though. In either case, a comment above
+ # the test shows how and why it differs from the test specification,
+ # or why it is commented out for now.
+ # When we do implement UDP IXFR, we should probably keep the TCP
+ # tests, and add them to the test specification, so we still have a
+ # 1-to-1 mapping between these tests and the specification document.
+ #
+ # These tests use a zone with just a few records, the first serial
+ # is 2, and it is incremented in steps of 2, up to serial 22.
+ # Each updates either deletes or adds the www.example.com A record.
+ # Version 2 has the record, then the update to version 4 deletes it,
+ # the update to 6 adds it again, and so on, until version 22 (where
+ # the last update has added it again)
+ #
+ # Some of the tests (scenario 1 tests 3 and 4, and scenario 2 tests 1 and
+ # 2 may still not work if we replicate BIND 9's behaviour; it always
+ # responds to UDP IXFR requests with just the SOA, and it does not do
+ # AXFR-style IXFR if the number of changes exceeds the size of the zone)
+ #
+ # So in effect, there is only one test that is currently active (scenario
+ # 1 test 7)
+
+
+ Scenario: Test Set 1
+ Given I have bind10 running with configuration ixfr-out/testset1-config.db
+ Then wait for bind10 xfrout to start
