This is the source for the development version of BIND 10.

BIND is the popular implementation of a DNS server, developer
interfaces, and DNS tools. BIND 10 is a rewrite of BIND 9. BIND 10
is written in C++ and Python and provides a modular environment
for serving, maintaining, and developing DNS.

BIND10-devel is new development leading up to the production
BIND 10 release. It contains prototype code and experimental
interfaces. Nevertheless it is ready to use now for testing the
new BIND 10 infrastructure ideas. The Year 2 milestones of the
five year plan are described here:

	https://bind10.isc.org/wiki/Year2Milestones

This release includes the bind10 master process, b10-msgq message
bus, b10-auth authoritative DNS server (with SQLite3 and in-memory
backends), b10-resolver recursive or forwarding DNS server, b10-cmdctl
remote control daemon, b10-cfgmgr configuration manager, b10-xfrin
AXFR inbound service, b10-xfrout outgoing AXFR service, b10-zonemgr
secondary manager, b10-stats statistics collection and reporting
daemon, and a new libdns++ library for C++ with a python wrapper.

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

BUILDING

See the Guide for detailed installation directions at
doc/guide/bind10-guide.html.

Simple build instructions:

  ./configure
  make

If building from Git repository, run:

  autoreconf --install

before running ./configure

Requires autoconf 2.59 or newer.

Use automake-1.11 or better for working Python 3.1 tests.
Alternatively, you could manually specify an absolute path to python
executable by the --with-pythonpath option of the configure script,
e.g.,
% ./configure --with-pythonpath=/usr/local/bin/python3.1

Operating-System specific tips:

- FreeBSD
  You may need to install a python binding for sqlite3 by hand.  A
  sample procedure is as follows:
  - add the following to /etc/make.conf
    PYTHON_VERSION=3.1
  - build and install the python binding from ports, assuming the top
    directory of the ports system is /usr/ports
  % cd /usr/ports/databases/py-sqlite3/
  % make
  % sudo make install

INSTALLATION

Install with:

  make install

TESTS

The tests use the googletests framework for C++. It is available
from http://code.google.com/p/googletest/.  To enable the tests,
configure BIND 10 with: 

  ./configure --with-gtest

Then run "make check" to run these tests.

TEST COVERAGE

Code coverage reports may be generated using make. These are
based on running on the unit tests. The resulting reports are placed
in coverage-cpp-html and coverage-python-html directories for C++
and Python, respectively.

The code coverage report for the C++ tests uses LCOV. It is available
from http://ltp.sourceforge.net/. To generate the HTML report,
first configure BIND 10 with:
 
  ./configure --with-lcov

The code coverage report for the Python tests uses coverage.py (aka
pycoverage). It is available from http://nedbatchelder.com/code/coverage/.
To generate the HTML report, first configure BIND 10 with:

  ./configure --with-pycoverage

Doing code coverage tests:

  make coverage
	Does the clean, perform, and report targets for C++ and Python.

  make clean-coverage
	Zeroes the code coverage counters and removes the HTML reports
	for C++ and Python.

  make perform-coverage
	Runs the C++ (using the googletests framework) and Python
	tests.

  make report-coverage
	Generates the coverage reports in HTML for C++ and Python.

  make clean-cpp-coverage
	Zeroes the code coverage counters and removes the HTML report
	for the C++ tests.

  make clean-python-coverage
	Zeroes the code coverage counters and removes the HTML report
	for the Python tests.

  make report-cpp-coverage
	Generates the coverage report in HTML for C++, excluding
	some unrelated headers.  The HTML reports are placed in a
	directory called coverage-cpp-html/.

  make report-python-coverage
	Generates the coverage report in HTML for Python. The HTML
	reports are placed in a directory called coverage-python-html/.

DEVELOPERS

The generated run_*.sh scripts available in the src/bin directories
are for running the code using the source tree.

RUNNING

You can start the BIND 10 processes by running bind10 which is
installed to the sbin directory under the installation prefix.
The default location is:

  /usr/local/sbin/bind10

For development work, you can also run the bind10 services from the
source tree:

 ./src/bin/bind10/run_bind10.sh 

(Which will use the modules and configurations also from the source
tree.)

CONFIGURATION

Commands can be given through the bindctl tool.

The server must be running for bindctl to work.

The following configuration commands are available

help: show the different command modules
<module> help: show the commands for module
<module> <command> help: show info for the command


config show [identifier]: Show the currently set values. If no identifier is
                          given, the current location is used. If a config
                          option is a list or a map, the value is not
                          shown directly, but must be requested separately.
config go [identifier]:   Go to the given location within the configuration.
config set [identifier] <value>: Set a configuration value.
config unset [identifier]: Remove a value (reverts to default if the option
                           is mandatory).
config add [identifier] <value>: add a value to a list
config remove [identifier] <value>: remove a value from a list 
config revert:	Revert all changes that have not been committed
config commit: Commit all changes
config diff: Show the changes that have not been committed yet
