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)
