	Development release of BIND 10: bind10-devel-20101201

We are pleased to announce the seventh development release of BIND
10.  BIND 10 provides a C++ library for DNS (with python wrappers)
and several cooperating daemons for providing authoritative DNS
service (with SQLite3 backend and DNSSEC). It contains prototype
code and experimental interfaces. Current development includes a
stats daemon for collecting and reporting statistics data. We are
also continuing work on the first phase of the recursive caching
DNS server.

Documentation is included and also available via the BIND 10
website at http://bind10.isc.org/

	ftp://ftp.isc.org/isc/bind10/devel-20101201/bind10-devel-20101201.tar.gz

A PGP signature of the distribution is at

	ftp://ftp.isc.org/isc/bind10/devel-20101201/bind10-devel-20101201.tar.gz.sha512.asc

The signature was generated with the ISC public key, which is

A summary of the significant changes since the previous release
include (from the ChangeLog):

  124.  [bug]		jreed
	Fix some wrong version reporting. Now also show the version
	for the component and BIND 10 suite. (Trac #302, svn r3696)

  123.  [bug]		jelte
	src/bin/bindctl printed values had the form of python literals
	(e.g. 'True'), while the input requires valid JSON (e.g. 'true').
	Output changed to JSON format for consistency. (svn r3694)

  122.  [func]		stephen
	src/bin/bind10: Added configuration options to Boss to determine
	whether to start the authoritative server, recursive server (or
	both). A dummy recursor has been provided for test purposes.
	(Trac #412, svn r3676)

  121.  [func]		jinmei
	src/lib/dns: Added support for TSIG RDATA.  At this moment this is
	not much of real use, however, because no protocol support was
	added yet.  It will soon be added. (Trac #372, svn r3649)

  120.  [func]		jinmei
	src/lib/dns: introduced two new classes, TSIGKey and TSIGKeyRing,
	to manage TSIG keys. (Trac #381, svn r3622)

  119.	[bug]		jinmei
	The master file parser of the python datasrc module incorrectly
	regarded a domain name beginning with a decimal number as a TTL
	specification.  This confused b10-loadzone and had it reject to
	load a zone file that contains such a name.
	Note: this fix is incomplete and the loadzone would still be
	confused if the owner name is a syntactically indistinguishable
	from a TTL specification.  This is part of a more general issue
	and will be addressed in Trac #413. (Trac #411, svn r3599)

  118.	[func]		jinmei
	src/lib/dns: changed the interface of
	AbstractRRset::getRdataIterator() so that the internal
	cursor would point to the first RDATA automatically.  This
	will be a more intuitive and less error prone behavior.
	This is a backward compatible change. (Trac #410, r3595)

  117.  [func]		jinmei
	src/lib/datasrc: added new zone and zone table classes for the
	support of in memory data source.  This is an intermediate step to
	the bigger feature, and is not yet actually usable in practice.
	(Trac #399, svn r3590)

  116.	[bug]		jerry
	src/bin/xfrout: Xfrout and Auth will communicate by long tcp
	connection, Auth needs to make a new connection only on the first
	time or if an error occurred.
	(Trac #299, svn r3482)

  115.	[func]*		jinmei
	src/lib/dns: Changed DNS message flags and section names from
	separate classes to simpler enums, considering the balance between
	type safety and usability.  API has been changed accordingly.
	More documentation and tests were provided with these changes.
	(Trac #358, r3439)

  114.	[build]		jinmei
	Supported clang++.  Note: Boost >= 1.44 is required.
	(Trac #365, svn r3383)

  113.	[func]*		zhanglikun
	Folder name 'utils'(the folder in /src/lib/python/isc/) has been
	renamed	to 'util'. Programs that used 'import isc.utils.process'
	now need to use 'import isc.util.process'. The folder
	/src/lib/python/isc/Util is removed since it isn't used by any
	program. (Trac #364, r3382)

  112.	[func]		zhang likun
	Add one mixin class to override the naive serve_forever() provided
	in python library socketserver. Instead of polling for shutdwon
	every poll_interval seconds, one socketpair is used to wake up
	the waiting server. (Trac #352, svn r3366)

  111.	[bug]*   zhanglikun, Michal Vaner
	Make sure process xfrin/xfrout/zonemgr/cmdctl can be stopped
	properly when user enter "ctrl+c" or 'Boss shutdown' command
	through bindctl.  The ZonemgrRefresh.run_timer and
	NotifyOut.dispatcher spawn a thread themselves.
	(Trac #335, svn r3273)

  110.  [func]      Michal Vaner
	Added isc.net.check module to check ip addresses and ports for
	correctness and isc.net.addr to hold IP address. The bind10, xfrin
	and cmdctl programs are modified to use it.
	(Trac #353, svn r3240)

  109.  [func]		naokikambe
	Added the initial version of the stats module for the statistics
	feature of BIND 10, which supports the restricted features and
	items and reports via bindctl command. (Trac #191, r3218)
	Added the document of the stats module, which is about how stats
	module collects the data (Trac #170, [wiki:StatsModule])

  108.	[func]		jerry
	src/bin/zonemgr: Provide customizable configurations for
	lowerbound_refresh, lowerbound_retry, max_transfer_timeout and
	jitter_scope. (Trac #340, r3205)

  107.  [func]       zhang likun
	Remove the parameter 'db_file' for command 'retransfer' of
	xfrin module. xfrin.spec will not be generated by script.
	(Trac #329, r3171)

  106.  [bug]       zhang likun
	When xfrin can't connect with one zone's master, it should tell
	the bad news to zonemgr, so that zonemgr can reset the timer for
	that zone. (Trac #329, r3170)

  105.  [bug]       Michal Vaner
	Python processes: they no longer take 100% CPU while idle
	due to a busy loop in reading command session in a nonblocking way.
	(Trac #349, svn r3153), (Trac #382, svn r3294)

  104.	[bug]		jerry
	bin/zonemgr: zonemgr should be attempting to refresh expired zones.
	(Trac #336, r3139)
 
  103.	[bug]		jerry
	lib/python/isc/log: Fixed an issue with python logging,
	python log shouldn't die with OSError. (Trac #267, r3137)
 
  102.	[build]		jinmei
	Disable threads in ASIO to minimize build time dependency.
	(Trac #345, r3100)

  101.	[func]		jinmei
	src/lib/dns: Completed Opcode and Rcode implementation with more
	tests and documentation.  API is mostly the same but the
	validation was a bit tightened. (Trac #351, svn r3056)

  100.  [func]      Michal Vaner
	Python processes: support naming of python processes so
	they're not all called python3.
	(Trac #322, svn r3052)

  99.	[func]*		jinmei
	Introduced a separate EDNS class to encapsulate EDNS related
	information more cleanly.  The related APIs are changed a bit,
	although it won't affect most of higher level applications.
	(Trac #311, svn r3020)

  98.	[build]		jinmei
	The ./configure script now tries to search some common include
	paths for boost header files to minimize the need for explicit
	configuration with --with-boost-include. (Trac #323, svn r3006)

  97.	[func]		jinmei
	Added a micro benchmark test for query processing of b10-auth.
	(Trac #308, svn r2982)

  96.	[bug]		jinmei
	Fixed two small issues with configure: Do not set CXXFLAGS so that
	it can be customized; Make sure --disable-static works.
	(Trac #325, r2976)

We look forward to hearing from you,
