Development release of BIND 10: bind10-devel-20110120
We are pleased to announce the eighth 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) and forwarding. It
contains prototype code and experimental interfaces.
New features in this snapshot include: new b10-resolver daemon that
currently does forwarding only, b10-stats provides a statistics
collector and aggregator, and in-memory data source for the
authoritative server.
I have been using this forwarder for my workstations for over 40
days.
Documentation is included and also available via the BIND 10
website at http://bind10.isc.org/

A summary of the significant changes since the previous release
include (from the ChangeLog):
155. [doc] jreed
Miscellaneous documentation improvements for man pages and
the guide, including auth, resolver, stats, xfrout, and
zonemgr. (git c14c4741b754a1eb226d3bdc3a7abbc4c5d727c0)
154. [bug] jinmei
b10-xfrin/b10-zonemgr: Fixed a bug where these programs didn't
receive command responses from CC sessions. Eventually the
receive buffer became full, and many other components that rely
on CC channels would stall (as noted in #420 and #513). This is
an urgent care fix due to the severity of the problem; we'll need
to revisit it for cleaner fix later. (Trac #516, git 62c72fc)
153. [bug] jelte
b10-cfgmgr: Fixed a bug where configuration updates sometimes
lost previous settings in the configuration manager.
(Trac #427, git 2df894155657754151e0860e2ca9cdbed7317c70)
152. [func]* jinmei
b10-auth: Added new configuration variable "statistics-interval"
to allow the user to change the timer interval for periodic
statistics updates. The update can also be disabled by setting
the value to 0. Disabling statistics updates will also work as
a temporary workaround of a known issue that b10-auth can block in
sending statistics and stop responding to queries as a result.
(Trac #513, git 285c5ee)
151. [bug] smann
lib/log/dummylog.h:
lib/log/dummylog.cc: Modify dlog so that it takes an optional 2nd
argument of type bool (true or false). This flag, if set, will cause
the message to be printed whether or not -v is chosen.
(trac #432, git 880220478c3e8702d56d761b1e0b21b77d08ee5a)
150. [bug] jelte
b10-cfgmgr: No longer save the configuration on exit. Configuration
is already saved if it is changed successfully, so writing it on
exit (and hence, when nothing has changed too) is unnecessary and
may even cause problems.
(Trac #435, git fd7baa38c08d54d5b5f84930c1684c436d2776dc)
149. [bug] jelte
bindctl: Check if the user session has disappeared (either by a
timeout or by a server restart), and reauthenticate if so. This
fixes the 'cmdctl not running' problem.
(trac #431, git b929be82fec5f92e115d8985552f84b4fdd385b9)
148. [func] jelte
bindctl: Command results are now pretty-printed (i.e. printed in
a more readable form). Empty results are no longer printed at all
(used to print '{}'), and the message
'send the command to cmd-ctrl' has also been removed.
(git 3954c628c13ec90722a2d8816f52a380e0065bae)
147. [bug] jinmei
python/isc/config: Fixed a bug that importing custom configuration
(in b10-config.db) of a remote module didn't work.
(Trac #478, git ea4a481)
146. [func] jelte
Command arguments were not validated internally against their
specifications. This change fixes that (on the C++ side, Python
side depends on an as yet planned addition). Note: this is only
an added internal check, the cli already checks format.
(Trac #473, git 5474eba181cb2fdd80e2b2200e072cd0a13a4e52)
145. [func]* jinmei
b10-auth: added a new command 'loadzone' for (re)loading a
specific zone. The command syntax is generic but it is currently
only feasible for class IN in memory data source. To reload a
zone "example.com" via bindctl, execute the command as follows:
> Auth loadzone origin = example.com
(Trac #467)
144. [build] jinmei
Introduced a workaround for clang++ build on FreeBSD (and probably
some other OSes). If building BIND 10 fails with clang++ due to
a link error about "__dso_handle", try again from the configure
script with CXX_LIBTOOL_LDFLAGS=-L/usr/lib (the path actually
doesn't matter; the important part is the -L flag). This
workaround is not automatically enabled as it's difficult to
detect the need for it dynamically, and must be enabled via the
variable by hand. (Trac #474, git cfde436)
143. [build] jinmei
Fixed build problems with clang++ in unit tests due to recent
changes. No behavior change. (Trac #448, svn r4133)
142. [func] jinmei
b10-auth: updated query benchmark so that it can test in memory
data source. Also fixed a bug that the output buffer isn't
cleared after query processing, resulting in misleading results
or program crash. This is a regression due to change #135.
(Trac #465, svn r4103)
141. [bug] jinmei
b10-auth: Fixed a bug that the authoritative server includes
trailing garbage data in responses. This is a regression due to
change #135. (Trac #462, svn r4081)
140. [func] y-aharen
src/bin/auth: Added a feature to count queries and send counter
values to statistics periodically. To support it, added wrapping
class of asio::deadline_timer to use as interval timer.
The counters can be seen using the "Stats show" command from
bindctl. The result would look like:
... "auth.queries.tcp": 1, "auth.queries.udp": 1 ...
Using the "Auth sendstats" command you can make b10-auth send the
counters to b10-stats immediately.
(Trac #347, svn r4026)
139. [build] jreed
Introduced configure option and make targets for generating
Python code coverage report. This adds new make targets:
report-python-coverage and clean-python-coverage. The C++
code coverage targets were renamed to clean-cpp-coverage
and report-cpp-coverage. (Trac #362, svn r4023)
138. [func]* jinmei
b10-auth: added a configuration interface to support in memory
data sources. For example, the following command to bindctl
will configure a memory data source containing the "example.com"
zone with the zone file named "example.com.zone":
> config set Auth/datasources/ [{"type": "memory", "zones": \
[{"origin": "example.com", "file": "example.com.zone"}]}]
By default, the memory data source is disabled; it must be
configured explicitly. To disable it again, specify a null list
for Auth/datasources:
> config set Auth/datasources/ []
Notes: it's currently for class IN only. The zone files are not
actually loaded into memory yet (which will soon be implemented).
This is an experimental feature and the syntax may change in
future versions.
(Trac #446, svn r3998)
137. [bug] jreed
Fix run_*.sh scripts that are used for development testing
so they use a msgq socket file in the build tree.
(Trac #226, svn r3989)
136. [bug] jelte
bindctl (and the configuration manager in general) now no longer
accepts 'unknown' data; i.e. data for modules that it does not know
about, or configuration items that are not specified in the .spec
files.
(Trac #202, svn r3967)
135. [func] each
Add b10-resolver. This is an example recursive server that
currently does forwarding only and no caching.
(Trac #327, svn r3903)
134. [func] vorner
b10-resolver supports timeouts and retries in forwarder mode.
(Trac #401, svn r3660)
133. [func] vorner
New temporary logging function available in isc::log. It is used by
b10-resolver.
(Trac #393, r3602)
132. [func] vorner
The b10-resolver is configured through config manager.
It has "listen_on" and "forward_addresses" options.
(Trac #389, r3448)
131. [func] feng, jerry
src/lib/datasrc: Introduced two template classes RBTree and RBNode
to provide the generic map with domain name as key and anything as
the value. Because of some unresolved design issue, the new classes
are only intended to be used by memory zone and zone table.
(Trac #397, svn r3890)
130. [func] jerry
src/lib/datasrc: Introduced a new class MemoryDataSrc to provide
the general interface for memory data source. For the initial
implementation, we don't make it a derived class of AbstractDataSrc
because the interface is so different(we'll eventually consider this
as part of the generalization work).
(Trac #422, svn r3866)
129. [func] jinmei
src/lib/dns: Added new functions masterLoad() for loading master
zone files. The initial implementation can only parse a limited
form of master files, but BIND 9's named-compilezone can convert
any valid zone file into the acceptable form.
(Trac #423, svn r3857)
128. [build] vorner
Test for query name = '.', type = DS to authoritative nameserver
for root zone was added.
(Trac #85, svn r3836)
127. [bug] stephen
During normal operation process termination and resurrection messages
are now output regardless of the state of the verbose flag.
(Trac #229, svn r3828)
126. [func] stephen, vorner, ocean
The Nameserver Address Store (NSAS) component has been added. It takes
care of choosing an IP address of a nameserver when a zone needs to be
contacted.
(Trac #356, Trac #408, svn r3823)
Please provide feedback about using BIND 10. We look forward to
hearing from you.
