-302. [defect] jelte
+319. [func] naokikambe
+ b10-stats-httpd was updated. In addition of the access to all
+ statistics items of all modules, the specified item or the items of the
+ specified module name can be accessed. For example, the URI requested
+ by using the feature is showed as "/bind10/statistics/xml/Auth" or
+ "/bind10/statistics/xml/Auth/queries.tcp". The list of all possible
+ module names and all possible item names can be showed in the root
+ document, whose URI is "/bind10/statistics/xml". This change is not
+ only for the XML documents but also is for the XSD and XSL documents.
+ (Trac #917, git b34bf286c064d44746ec0b79e38a6177d01e6956)
+
+318. [func] stephen
+ Add C++ API for accessing zone difference information in database-based
+ data sources.
+ (Trac #1330, git 78770f52c7f1e7268d99e8bfa8c61e889813bb33)
+
+317. [func] vorner
+ datasrc: the getUpdater method of DataSourceClient supports an optional
+ 'journaling' parameter to indicate the generated updater to store diffs.
+ The database based derived class implements this extension.
+ (Trac #1331, git 713160c9bed3d991a00b2ea5e7e3e7714d79625d)
+
+316. [func]* vorner
+ The configuration of what parts of the system run is more flexible now.
+ Everything that should run must have an entry in Boss/components.
+ (Trac #213, git 08e1873a3593b4fa06754654d22d99771aa388a6)
+
+315. [func] tomek
+ libdhcp: Support for DHCPv4 packet manipulation is now implemented.
+ All fixed fields are now supported. Generic support for DHCPv4
+ options is available (both parsing and assembly). There is no code
+ that uses this new functionality yet, so it is not usable directly
+ at this time. This code will be used by upcoming b10-dhcp4 daemon.
+ (Trac #1228, git 31d5a4f66b18cca838ca1182b9f13034066427a7)
+
+314. [bug] jelte
+ b10-xfrin would previously initiate incoming transfers upon
+ receiving NOTIFY messages from any address (if the zone was
+ known to b10-xfrin, and using the configured address). It now
+ only starts a transfer if the source address from the NOTIFY
+ packet matches the configured master address and port. This was
+ really already fixed in release bind10-devel-20111014, but there
+ were some deferred cleanups to add.
+ (Trac #1298, git 1177bfe30e17a76bea6b6447e14ae9be9e1ca8c2)
+
+313. [func] jinmei
+ datasrc: Added C++ API for adding zone differences to database
+ based data sources. It's intended to be used for the support for
+ IXFR-in and dynamic update (so they can subsequently be retrieved
+ for IXFR-out). The addRecordDiff method of the DatabaseAccessor
+ defines the interface, and a concrete implementation for SQLite3
+ was provided.
+ (Trac #1329, git 1aa233fab1d74dc776899df61181806679d14013)
+
+312. [func] jelte
+ Added an initial framework for doing system tests using the
+ cucumber-based BDD tool Lettuce. A number of general steps are
+ included, for instance running bind10 with specific
+ configurations, sending queries, and inspecting query answers. A
+ few very basic tests are included as well.
+ (Trac #1290, git 6b75c128bcdcefd85c18ccb6def59e9acedd4437)
+
+311. [bug] jelte
+ Fixed a bug in bindctl where tab-completion for names that
+ contain a hyphen resulted in unexpected behaviour, such as
+ appending the already-typed part again.
+ (Trac #1345, git f80ab7879cc29f875c40dde6b44e3796ac98d6da)
+
+310. [bug] jelte
+ Fixed a bug where bindctl could not set a value that is optional
+ and has no default, resulting in the error that the setting
+ itself was unknown. bindctl now correctly sees the setting and
+ is able to set it.
+ (Trac #1344, git 0e776c32330aee466073771600390ce74b959b38)
+
+309. [bug] jelte
+ Fixed a bug in bindctl where the removal of elements from a set
+ with default values was not stored, unless the set had been
+ modified in another way already.
+ (Trac #1343, git 25c802dd1c30580b94345e83eeb6a168ab329a33)
+
+308. [build] jelte
+ The configure script will now use pkg-config for finding
+ information about the Botan library. If pkg-config is unavailable,
+ or unaware of Botan, it will fall back to botan-config. It will
+ also use botan-config when a specific botan library directory is
+ given using the '--with-botan=' flag
+ (Trac #1194, git dc491833cf75ac1481ba1475795b0f266545013d)
+
+307. [func] vorner
+ When zone transfer in fails with IXFR, it is retried with AXFR
+ automatically.
+ (Trac #1279, git cd3588c9020d0310f949bfd053c4d3a4bd84ef88)
+
+306. [bug] Stephen
+ Boss process now waits for the configuration manager to initialize
+ itself before continuing with startup. This fixes a race condition
+ whereby the Boss could start the configuration manager and then
+ immediately start components that depended on that component being
+ fully initialized.
+ (Trac #1271, git 607cbae949553adac7e2a684fa25bda804658f61)
+
+305. [bug] jinmei
+ Python isc.dns, isc.datasrc, xfrin, xfrout: fixed reference leak
+ in Message.get_question(), Message.get_section(),
+ RRset.get_rdata(), and DataSourceClient.get_updater().
+ The leak caused severe memory leak in b10-xfrin, and (although no
+ one reported it) should have caused less visible leak in
+ b10-xfrout. b10-xfrin had its own leak, which was also fixed.
+ (Trac #1028, git a72886e643864bb6f86ab47b115a55e0c7f7fcad)
+
+304. [bug] jelte
+ The run_bind10.sh test script now no longer runs processes from
+ an installed version of BIND 10, but will correctly use the
+ build tree paths.
+ (Trac #1246, git 1d43b46ab58077daaaf5cae3c6aa3e0eb76eb5d8)
+
+303. [bug] jinmei
+ Changed the installation path for the UNIX domain file used
+ for the communication between b10-auth and b10-xfrout to a
+ "@PACKAGE@" subdirectory (e.g. from /usr/local/var to
+ /usr/local/var/bind10-devel). This should be transparent change
+ because this file is automatically created and cleaned up, but
+ if the old file somehow remains, it can now be safely removed.
+ (Trac #869, git 96e22f4284307b1d5f15e03837559711bb4f580c)
+
+302. [bug] jelte
msgq no longer crashes if the remote end is closed while msgq
tries to send data. It will now simply drop the message and close
the connection itself.

+ * by the iterator. In that sense this method is redundant, but is

+--
+-- This is a short-term solution to creating the differences table for testing
+-- purposes.
+--
+-- It is assumed that the database used is a copy of the "example.org.sqlite3"
+-- database in this test directory. The diffs table is created and populated
+-- with a set of RRs that purport to represent differences that end in the
+-- zone as is.
+--
+-- The file can be executed by the command:
+-- % sqlite3 -init <this-file> <database-file> ".quit"
+--
+-- The file gets executed as the set of SQL statements on the database file,
+-- the ".quit" on the command line then getting executed to exit SQLite3.
+
+-- Create the diffs table

+BIND10 system testing with Lettuce
+or: to BDD or not to BDD
+
+In this directory, we define a set of behavioral tests for BIND 10. Currently,
+these tests are specific for BIND10, but we are keeping in mind that RFC-related
+tests could be separated, so that we can test other systems as well.
+
+Prerequisites:
+- Installed version of BIND 10 (but see below how to run it from source tree)
+- dig
+- lettuce (http://lettuce.it)
+
+To install lettuce, if you have the python pip installation tool, simply do
+pip install lettuce
+See http://lettuce.it/intro/install.html
+
+Most systems have the pip tool in a separate package; on Debian-based systems
+it is called python-pip. On FreeBSD the port is devel/py-pip.
+
+Running the tests
+-----------------
+
+At this moment, we have a fixed port for local tests in our setups, port 47806.
+This port must be free. (TODO: can we make this run-time discovered?).
+Port 47805 is used for cmdctl, and must also be available.
+(note, we will need to extend this to a range, or if possible, we will need to
+do some on-the-fly available port finding)
+
+The bind10 main program, bindctl, and dig must all be in the default search
+path of your environment, and BIND 10 must not be running if you use the
+installed version when you run the tests.
+
+If you want to test an installed version of bind 10, just run 'lettuce' in
+this directory.
+
+We have provided a script that sets up the shell environment to run the tests
+with the build tree version of bind. If your shell uses export to set
+environment variables, you can source the script setup_intree_bind10.sh, then
+run lettuce.
+
+Due to the default way lettuce prints its output, it is advisable to run it
+in a terminal that is wide than the default. If you see a lot of lines twice
+in different colors, the terminal is not wide enough.
+
+If you just want to run one specific feature test, use
+lettuce features/<feature file>
+
+To run a specific scenario from a feature, use
+lettuce features/<feature file> -s <scenario number>
+
+We have set up the tests to assume that lettuce is run from this directory,
+so even if you specify a specific feature file, you should do it from this
+directory.
+
+What to do when a test fails
+----------------------------
+
+First of all, look at the error it printed and see what step it occurred in.
+If written well, the output should explain most of what went wrong.
+
+The stacktrace that is printed is *not* of bind10, but of the testing
+framework; this helps in finding more information about what exactly the test
+tried to achieve when it failed (as well as help debug the tests themselves).
+
+Furthermore, if any scenario fails, the output from long-running processes
+will be stored in the directory output/. The name of the files will be
+<Feature name>-<Scenario name>-<Process name>.stdout and
+<Feature name>-<Scenario name>-<Process name>.stderr
+Where spaces and other non-standard characters are replaced by an underscore.
+The process name is either the standard name for said process (e.g. 'bind10'),
+or the name given to it by the test ('when i run bind10 as <name>').
+
+These files *will* be overwritten or deleted if the same scenarios are run
+again, so if you want to inspect them after a failed test, either do so
+immediately or move the files.
+
+Adding and extending tests
+--------------------------
+
+If you want to add tests, it is advisable to first go through the examples to
+see what is possible, and read the documentation on http://www.lettuce.it
+
+There is also a README.tutorial file here.
+
+We have a couple of conventions to keep things manageable.
+
+Configuration files go into the configurations/ directory.
+Data files go into the data/ directory.
+Step definition go into the features/terrain/ directory (the name terrain is
+chosen for the same reason Lettuce chose terrain.py, this is the place the
+tests 'live' in).
+Feature definitions go directly into the features/ directory.
+
+These directories are currently not divided further; we may want to consider
+this as the set grows. Due to a (current?) limitation of Lettuce, for
+feature files this is currently not possible; the python files containing
+steps and terrain must be below or at the same level of the feature files.
+
+Long-running processes should be started through the world.RunningProcesses
+instance. If you want to add a process (e.g. bind9), create start, stop and
+control steps in terrain/<base_name>_control.py, and let it use the
+RunningProcesses API (defined in terrain.py). See bind10_control.py for an
+example.
+
+For sending queries and checking the results, steps have been defined in
+terrain/querying.py. These use dig and store the results split up into text
+strings. This is intentionally not parsed through our own library (as that way
+we might run into a 'symmetric bug'). If you need something more advanced from
+query results, define it here.
+
+Some very general steps are defined in terrain/steps.py.
+Initialization code, cleanup code, and helper classes are defined in
+terrain/terrain.py.
+
+To find the right steps, case insensitive matching is used. Parameters taken
+from the steps are case-sensitive though. So a step defined as
+'do foo with value (bar)' will be matched when using
+'Do Foo with value xyz', but xyz will be taken as given.
+
+If you need to add steps that are very particular to one test, create a new
+file with a name relevant for that test in terrain. We may want to consider
+creating a specific subdirectory for these, but at this moment it is unclear
+whether we need to.
+
+We should try to keep steps as general as possible, while not making them to
+complex and error-prone.

+Quick tutorial and overview
+---------------------------
+
+Lettuce is a framework for doing Behaviour Driven Development (BDD).
+
+The idea behind BDD is that you first write down your requirements in
+the form of scenarios, then implement their behaviour.
+
+We do not plan on doing full BDD, but such a system should also help
+us make system tests. And, hopefully, being able to better identify
+what exactly is going wrong when a test fails.
+
+Lettuce is a python implementation of the Cucumber framework, which is
+a ruby system. So far we chose lettuce because we already need python
+anyway, so chances are higher that any system we want to run it on
+supports it. It only supports a subset of cucumber, but more cucumber
+features are planned. As I do not know much details of cucumber, I
+can't really say what is there and what is not.
+
+A slight letdown is that the current version does not support python 3.
+However, as long as the tool-calling glue is python2, this should not
+cause any problems, since these aren't unit tests; We do not plan to use
+our libraries directly, but only through the runnable scripts and
+executables.
+
+-----
+
+Features, Scenarios, Steps.
+
+Lettuce makes a distinction between features, scenarios, and steps.
+
+Features are general, well, features. Each 'feature' has its own file
+ending in .feature. A feature file contains a description and a number
+of scenarios. Each scenario tests one or more particular parts of the
+feature. Each scenario consists of a number of steps.
+
+So let's open up a simple one.
+
+-- example.feature
+Feature: showing off BIND 10
+ This is to show BIND 10 running and that it answer queries
+
+ Scenario: Starting bind10
+ # steps go here
+--
+
+I have predefined a number of steps we can use, as we build test we
+will need to expand these, but we will look at them shortly.
+
+This file defines a feature, just under the feature name we can
+provide a description of the feature.
+
+The one scenario we have no has no steps, so if we run it we should
+see something like:
+
+-- output
+> lettuce
+Feature: showing off BIND 10
+ This is to show BIND 10 running and that it answer queries
+
+ Scenario: Starting bind10
+
+1 feature (1 passed)
+1 scenario (1 passed)
+0 step (0 passed)
+--
+
+Let's first add some steps that send queries.
+
+--
+ A query for www.example.com should have rcode REFUSED
+ A query for www.example.org should have rcode NOERROR
+--
+
+Since we didn't start any bind10, dig will time out and the result
+should be an error saying it got no answer. Errors are in the
+form of stack traces (trigger by failed assertions), so we can find
+out easily where in the tests they occurred. Especially when the total
+set of steps gets bigger we might need that.
+
+So let's add a step that starts bind10.
+
+--
+ When I start bind10 with configuration example.org.config
+--
+
+This is not good enough; it will fire of the process, but setting up
+b10-auth may take a few moments, so we need to add a step to wait for
+it to be started before we continue.
+
+--
+ Then wait for bind10 auth to start
+--
+
+And let's run the tests again.
+
+--
+> lettuce
+
+Feature: showing off BIND 10
+ This is to show BIND 10 running and that it answer queries
+
+ Scenario: Starting bind10
+ When I start bind10 with configuration example.org.config
+ Then wait for bind10 auth to start
+ A query for www.example.com should have rcode REFUSED
+ A query for www.example.org should have rcode NOERROR
+
+1 feature (1 passed)
+1 scenario (1 passed)
+4 steps (4 passed)
+(finished within 2 seconds)
+--
+
+So take a look at one of those steps, let's pick the first one.
+
+A step is defined through a python decorator, which in essence is a regular
+expression; lettuce searches through all defined steps to find one that
+matches. These are 'partial' matches (unless specified otherwise in the
+regular expression itself), so if the step is defined with "do foo bar", the
+scenario can add words for readability "When I do foo bar".
+
+Each captured group will be passed as an argument to the function we define.
+For bind10, i defined a configuration file, a cmdctl port, and a process
+name. The first two should be self-evident, and the process name is an
+optional name we give it, should we want to address it in the rest of the
+tests. This is most useful if we want to start multiple instances. In the
+next step (the wait for auth to start), I added a 'of <instance>'. So if we
+define the bind10 'as b10_second_instance', we can specify that one here as
+'of b10_second_instance'.
+
+--
+ When I start bind10 with configuration second.config
+ with cmdctl port 12345 as b10_second_instance
+--
+(line wrapped for readability)
+
+But notice how we needed two steps, which we probably always need (but
+not entirely always)? We can also combine steps; for instance:
+
+--
+ at step('have bind10 running(?: with configuration ([\w.]+))?')
+def have_bind10_running(step, config_file):
+ step.given('start bind10 with configuration ' + config_file)
+ step.given('wait for bind10 auth to start')
+--
+
+Now we can replace the two steps with one:
+
+--
+ Given I have bind10 running
+--
+
+That's it for the quick overview. For some more examples, with comments,
+take a look at features/example.feature. You can read more about lettuce and
+its features on http://www.lettuce.it, and if you plan on adding tests and
+scenarios, please consult the last section of the main README first.

+Feature: Example feature
+ This is an example Feature set. Is is mainly intended to show
+ our use of the lettuce tool and our own framework for it
+ The first scenario is to show what a simple test would look like, and
+ is intentionally uncommented.
+ The later scenarios have comments to show what the test steps do and
+ support
+
+ Scenario: A simple example
+ Given I have bind10 running with configuration example.org.config
+ A query for www.example.org should have rcode NOERROR
+ A query for www.doesnotexist.org should have rcode REFUSED
+ The SOA serial for example.org should be 1234
+
+ Scenario: New database
+ # This test checks whether a database file is automatically created
+ # Underwater, we take advantage of our intialization routines so
+ # that we are sure this file does not exist, see
+ # features/terrain/terrain.py
+
+ # Standard check to test (non-)existence of a file
+ # This file is actually automatically
+ The file data/test_nonexistent_db.sqlite3 should not exist
+
+ # In the first scenario, we used 'given I have bind10 running', which
+ # is actually a compound step consisting of the following two
+ # one to start the server
+ When I start bind10 with configuration no_db_file.config
+ # And one to wait until it reports that b10-auth has started
+ Then wait for bind10 auth to start
+
+ # This is a general step to stop a named process. By convention,
+ # the default name for any process is the same as the one we
+ # use in the start step (for bind 10, that is 'I start bind10 with')
+ # See scenario 'Multiple instances' for more.
+ Then stop process bind10
+
+ # Now we use the first step again to see if the file has been created
+ The file data/test_nonexistent_db.sqlite3 should exist
+
+ Scenario: example.org queries
+ # This scenario performs a number of queries and inspects the results
+ # Simple queries have already been show, but after we have sent a query,
+ # we can also do more extensive checks on the result.
+ # See querying.py for more information on these steps.
+
+ # note: lettuce can group similar checks by using tables, but we
+ # intentionally do not make use of that here
+
+ # This is a compound statement that starts and waits for the
+ # started message
+ Given I have bind10 running with configuration example.org.config
+
+ # Some simple queries that is not examined further
+ A query for www.example.com should have rcode REFUSED
+ A query for www.example.org should have rcode NOERROR
+
+ # A query where we look at some of the result properties
+ A query for www.example.org should have rcode NOERROR
+ The last query response should have qdcount 1
+ The last query response should have ancount 1
+ The last query response should have nscount 3

+ # The answer section can be inspected in its entirety; in the future

+ A query for www.example.org type A class IN to 127.0.0.1:47806 should have rcode NOERROR
+
+ Scenario: changing database
+ # This scenario contains a lot of 'wait for' steps
+ # If those are not present, the asynchronous nature of the application
+ # can cause some of the things we send to be handled out of order;
+ # for instance auth could still be serving the old zone when we send
+ # the new query, or already respond from the new database.

+ # This scenario outlines every single step, and does not use

+Feature: Xfrin
+ Tests for Xfrin, specific for BIND 10 behaviour.
+
+ Scenario: Retransfer command
+ Given I have bind10 running with configuration xfrin/retransfer_master.conf with cmdctl port 47804 as master
+ And I have bind10 running with configuration xfrin/retransfer_slave.conf
+ A query for www.example.org should have rcode REFUSED
+ When I send bind10 the command Xfrin retransfer example.org IN 127.0.0.1 47807
+ Then wait for new bind10 stderr message XFRIN_XFR_TRANSFER_SUCCESS not XFRIN_XFR_PROCESS_FAILURE
+ A query for www.example.org should have rcode NOERROR
