ChangeLog

@@ -1,7 +1,85 @@
-  108.	[func]		jerry		
+  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 stoped
+	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

+.PP
+The
+\fBb10\-stats\fR
+is a daemon forked by
+\fBbind10\fR\&. Stats module collects statistics data from each module and reports statistics information via
+\fBbindctl\fR\&. It communicates by using the Command Channel by

+with other modules like
+\fBbind10\fR,
+\fBb10\-auth\fR
+and so on\&. It waits for coming data from other modules, then other modules send data to stats module periodically\&. Other modules send stats data to stats module independently from implementation of stats module, so the frequency of sending data may not be constant\&. Stats module collects data and aggregates it\&.

+The arguments are as follows:

-= Statistics overview =
-
-Result of 26 Jan 2010 evening discussion,
-statistics overview was almost fixed.
-
-Statsd listens msgq "statistics" channel, gathers statistics
-from each BIND 10 components and dump them into a XML file periodically.
-
-= Statsd current status =
-
-Statsd can run with msgq.
-Statsd is not controlled by BoB.
-Statsd does not read configuration from cfgd.
-File path, dump frequency, rotate generations are fixed.
-Statsd dumps to "/tmp/stats" every 10 seconds except no statistics received.
-"/tmp/stats" are preserved 100 generations.
-
-Current implementation is put on "bind10/branches/parkinglot/src/bin/stats/".
-
-= statistics channel Message format =
-
-The Statsd accepts python dictionary format data from msgq
-"statistics" channel.
-
-The data need to contain "components", "version", "timestamp", "stats" keys.
-
-The statistics data format is { "component" : "<component_name>",
-"version": "<version number>", "timestamp": "<unixtime>", "stats":
-<python dictionary format statistics>}.
-
-"stats" data may be nested.
-"stats" data is defined by each component.
-
-Each component sends statistics data to "statistics" group periodically
-without joining the group.
-
-See a example component: "stats/test/test-agent.py".
-
-= How to publish statistics from each component =
-
-For example, parkinglot auth server has one "counter".
-Then, parkinglot's statistics message may be
- { "component":"parkinglot", "version":1, "timestamp":unixtime,
-   stats: { "counter": counter } }.
-Send it to msgq "statistics" channel periodically
-(For example, every 10 second).
-
-Then "Statsd" will write it to the statistics file periodically.
-

-- read configuration from cfgd.
-- how to publish statistics data
