+746. [func] tomek
+ IOAddress no longer exposes underlying asio objects. The getAddress()
+ method has been removed and replaced with several convenience methods.
+ (Trac #1485, git ecdb62db16b3f3d447db4a9d2a4079d5260431f0)
+
+745. [bug] muks
+ b10-auth now returns rcode=REFUSED for all questions with
+ qtype=RRSIG (i.e., where RRSIGs are queried directly). This is
+ because RRSIGs are meaningless without being bundled alongside the
+ RRs they cover.
+ (Trac #2226, git 68d24e65c9c3dfee38adfbe1c93367b0083f9a58)
+
+744. [func] marcin
+ b10-dhcp6: Refactored the code which is processing Client FQDN option.
+ The major user-visible change is that server generates DDNS
+ NameChangeRequest for the first IPv6 address (instead of all)
+ acquired by a client. Also, the server generates fully qualified domain
+ name from acquired IPv6 address, if the client sends an empty name in
+ Client FQDN option.
+ (Trac# 3295, git aa1c94a54114e848c64771fde308fc9ac0c00fd0)
+
+743. [func] tmark
+ b10-dhcp4 now responds with changes in DDNS behavior based upon
+ configuration parameters specified through its dhcp-ddns configuration
+ element. The parameters now supported are override-no-update,
+ override-client-update, replace-client-name, generated-prefix, and
+ qualifying-suffix.
+ (Trac# 3282, git 42b1f1e4c4f5aa48b7588233402876f5012c043c)
+
+742. [func] muks
+ The authoritative server now includes the datasource configuration
+ when logging some errors with the
+ AUTH_DATASRC_CLIENTS_BUILDER_RECONFIGURE_ERROR message ID.
+ (Trac #2756, git 31872754f36c840b4ec0b412a86afe9f38be86e0)
+
+741. [bug] shane
+ Remove hard-coded (and unnecessary) TSIG key from error message.
+ This also prevents a crash if the TSIG name is missing.
+ (Trac #3099, git 0ba8bbabe09756a4627e80aacdbb5050407faaac)
+
+740. [func] muks
+ When displaying messages about mismatched configuration data types
+ in entered values (between the supplied value type and expected
+ schema type), bindctl now includes both the supplied and expected
+ configuration data types in the returned error. The user has more
+ information on what caused the error now.
+ (Trac #3239, git 84d5eda2a6ae0d737aef68d56023fc33fef623e6)
+
+739. [bug] muks
+ Various minor updates were made to the SSHFP RDATA parser. Mainly,
+ the SSHFP constructor no longer throws an isc::BadValue exception.
+ generic::SSHFP::getFingerprintLen() was also renamed to
+ getFingerprintLength().
+ (Trac #3287, git 2f26d781704618c6007ba896ad3d9e0c107d04b0)
+
+738. [bug] muks
+ b10-auth now correctly processes NXDOMAIN results in the root zone
+ when using a SQLite3 data source.
+ (Trac #2951, git 13685cc4580660eaf5b041b683a2d2f31fd24de3)
+
+737. [func] muks
+ b10-auth now additionally logs the source address and port when
+ DNS messages with unsupported opcodes are received.
+ (Trac #1516, git 71611831f6d1aaaea09143d4837eddbd1d67fbf4)
+
+736. [bug] wlodek
+ b10-dhcp6 is now capable to determine if a received
+ message is addressed to it, using server identifier option.
+ The messages with non-matching server identifier are dropped.
+ (Trac #2892, git 3bd69e9b4ab9be231f7c966fd62b95a4e1595901)
+
+735. [doc] stephen
+ Expanded Developer's Guide to include chapter on logging.
+ (Trac #2566, git a08d702839d9df6cddefeccab1e7e657377145de)
+
+734. [bug] marcin
+ libdhcp++: fixed a bug which caused an error when setting boolean
+ values for an option. Also, bind10-guide has been updated with the
+ examples how to set the boolean values for an option.
+ (Trac# 3292, git 7c4c0514ede3cffc52d8c2874cdbdb74ced5f4ac)
+
+733. [bug] marcin
+ libdhcp++: a function which opens IPv6/UDPv6 sockets for the
+ DHCPv6 server, gracefully handles errors to bind socket to
+ a multicast address.
+ (Trac #3288, git 76ace0c46a5fe0e53a29dad093b817ad6c891f1b)
+
+732. [func] tomek
+ b10-dhcp4, b10-dhcp6: Support for simplified client classification
+ added. Incoming packets are now assigned to a client class based on
+ the content of the packet's user class option (DHCPv4) or vendor class
+ option (DHCPv6). Two classes (docsis3.0 and eRouter1.0) have class
+ specific behavior in b10-dhcp4. See DHCPv4 Client Classification and
+ DHCPv6 Client Classification in BIND10 Developer's Guide for details.
+ This is a first ticket in a series of planned at least three tickets.
+ (Trac #3203, git afea612c23143f81a4201e39ba793bc837c5c9f1)
+
+731. [func] tmark
+ b10-dhcp4 now parses parameters which support DHCP-DDNS updates via
+ the DHCP-DDNS module, b10-dhcp-ddns. These parameters are part of new
+ configuration element, dhcp-ddns, defined in dhcp4.spec. The parameters
+ parse, store and retrieve but do not yet govern behavior. That will be
+ provided under separate ticket.
+ (Trac# 3033, git 0ba859834503f2b9b908cd7bc572e0286ca9201f)
+
+730. [bug] tomek
+ b10-dhcp4, b10-dhcp6: Both servers used to unnecessarily increase
+ subnet-id values after reconfiguration. The subnet-ids are now reset
+ to 1 every time a server is reconfigured.
+ (Trac #3234, git 31e416087685a6dadc3047fdbb0927bbf60095aa)
+
+729. [bug] marcin
+ b10-dhcp4 discards DHCPv4 messages carrying server identifiers
+ which don't match server identifiers used by the server.
+ (Trac #3279, git 805d2b269c6bf3e7be68c13f1da1709d8150a666)
+
728. [func] marcin
b10-dhcp6: If server fails to open a socket on one interface it
will log a warning and continue to open sockets on other interfaces.

+ at section dhcpv4Classifier DHCPv4 Client Classification
+
+Kea DHCPv4 server currently supports simplified client classification. It is called
+"simplified", because the incoming packets are classified based on the content
+of the vendor class (60) option. More flexible classification is planned, but there
+are no specific development dates agreed.
+
+For each incoming packet, @ref isc::dhcp::Dhcpv4Srv::classifyPacket() method is called.
+It attempts to extract content of the vendor class option and interpret as a name
+of the class. For now, the code has been tested with two classes used in cable modem
+networks: eRouter1.0 and docsis3.0, but any other content of the vendor class option will
+be interpreted as a class name.
+
+In principle any given packet can belong to zero or more classes. As the current
+classifier is very modest, there's only one way to assign a class (based on vendor class
+option), the ability to assign more than one class to a packet is not yet exercised.
+Neverthless, there is such a possibility and it will be used in a near future. To
+check whether a packet belongs to given class, isc::dhcp::Pkt4::inClass method should
+be used.
+
+Currently there is a short code section that alternates packet processing depending on
+which class it belongs to. It is planned to move that capability to an external hook
+library. See ticket #3275. The class specific behavior is:
+
+- docsis3.0 packets have siaddr (next server) field set
+- docsis3.0 packets have file field set to the content of the boot-file-name option
+- eRouter1.0 packets have siaddr (next server) field cleared
+
+Aforementioned modifications are conducted in @ref isc::dhcp::Dhcpv4Srv::classSpecificProcessing.
+

+For each incoming packet, @ref isc::dhcp::Dhcpv6Srv::classifyPacket() method is
+called. It attempts to extract content of the vendor class option and interprets
+as a name of the class. Although the RFC3315 says that the vendor class may
+contain more than one chunk of data, the existing code handles only one data
+block, because that is what actual devices use. For now, the code has been
+tested with two classes used in cable modem networks: eRouter1.0 and docsis3.0,
+but any other content of the vendor class option will be interpreted as a class
+name.
+
+In principle any given packet can belong to zero or more classes. As the current
+classifier is very modest, there's only one way to assign a class (based on vendor class
+option), the ability to assign more than one class to a packet is not yet exercised.
+Neverthless, there is such a possibility and it will be used in a near future. To
+check whether a packet belongs to given class, isc::dhcp::Pkt6::inClass method should
+be used.
+
+Currently there is no class behaviour coded in DHCPv6, hence no v6 equivalent of
+ at ref isc::dhcp::Dhcpv4Srv::classSpecificProcessing. Should any need for such a code arise,
+it will be conducted in an external hooks library.

-/// @brief A macro which handles an error in IfaceMgr.
-///
-/// There are certain cases when IfaceMgr may hit an error which shouldn't
-/// result in interruption of the function processing. A typical case is
-/// the function which opens sockets on available interfaces for a DHCP
-/// server. If this function fails to open a socket on a specific interface
-/// (for example, there is another socket already open on this interface
-/// and bound to the same address and port), it is desired that the server
-/// logs a warning but will try to open sockets on other interfaces. In order
-/// to log an error, the IfaceMgr will use the error handler function provided
-/// by the server and pass an error string to it. When the handler function
-/// returns, the IfaceMgr will proceed to open other sockets. It is allowed
-/// that the error handler function is not installed (is NULL). In these
-/// cases it is expected that the exception is thrown instead. A possible
-/// solution would be to enclose this conditional behavior in a function.
-/// However, despite the hate for macros, the macro seems to be a bit
-/// better solution in this case as it allows to convenietly pass an

+///
+/// There are certain cases when IfaceMgr may hit an error which shouldn't
+/// result in interruption of the function processing. A typical case is
+/// the function which opens sockets on available interfaces for a DHCP
+/// server. If this function fails to open a socket on a specific interface
+/// (for example, there is another socket already open on this interface
+/// and bound to the same address and port), it is desired that the server
+/// logs a warning but will try to open sockets on other interfaces. In order
+/// to log an error, the IfaceMgr will use the error handler function provided
+/// by the server and pass an error string to it. When the handler function
+/// returns, the IfaceMgr will proceed to open other sockets. It is allowed
+/// that the error handler function is not installed (is NULL). In these
+/// cases it is expected that the exception is thrown instead. A possible
+/// solution would be to enclose this conditional behavior in a function.
+/// However, despite the hate for macros, the macro seems to be a bit
+/// better solution in this case as it allows to convenietly pass an
+/// error string in a stream (not as a string).
+///

-This directory holds the first release of the logging system.
-
-
-Basic Ideas
-===========
-The BIND-10 logging system merges two ideas:
-
-* A hierarchical logging system similar to that used in Java (i.e. log4j)
-* Separation of message use from message text
-
-
-Hierarchical Logging System
-===========================
-When a program writes a message to the logging system, it does so using an
-instance of the Logger class. As well as performing the write of the message,
-the logger identifies the source of the message: different sources can write
-to different destinations and can log different severities of messages.
-For example, the "cache" logger could write messages of DEBUG severity or
-above to a file while all other components write messages of "INFO" severity
-or above to the Syslog file.
-
-The loggers are hierarchical in that each logger is the child of another
-logger. The top of the hierarchy is the root logger, which does not have
-a parent. The point of the hierarchy is that unless a logger is explicitly
-assigned an attribute (such as severity of message being logger), it picks
-it up from the parent. (In BIND-10, there is the root logger (named after
-the program) and every other logger is a child of that.) So in the example
-above, the INFO/Syslog attributes could be associated with the root logger
-while the DEBUG/file attributes are associated with the "cache" logger.
-
-
-Separation of Messages Use from Message Text
-============================================
-By separating the use of the message from the text associated with this -
-in essence, defining message text in an external file - it is possible to
-replace the supplied text of the messages with a local language version.
-
-Each message is identified by an identifier e.g. "LOG_WRITE_ERROR".
-Within the program, this is the symbol passed to the logging system.
-The logger system uses the symbol as an index into a dictionary to
-retrieve the message associated with it (e.g. "unable to open %s for
-input"). It then substitutes any message parameters (in this example,
-the name of the file where the write operation failed) and logs it to
-the destination.
-
-In BIND-10, a the default text for each message is linked into the
-program. Each program is able to read a locally-defined message file
-when it starts, updating the stored definitions with site-specific text.
-When the message is logged, the updated text is output. However, the
-message identifier is always included in the output so that the origin
-of the message can be identified even if the text has been changed.
-
-
-Using The System
-================
-The steps in using the system are:
-
-1. Create a message file. This defines messages by an identification - a
- mnemonic for the message, the convention being that these are a few
- words separated by underscores - and text that explains the message in
- more detail. The file is described in more detail below.
-
- Ideally the file should have a file type of ".mes".
-
-2. Run it through the message compiler to produce the .h and .cc files. This
- step should be included in the build process. (For an example of how to
- do this, see src/lib/nsas/Makefile.am.) During development though, the
- message compiler (found in the "src/lib/log/compiler" directory) will need
- to be run manually. The only argument is the name of the message file: it
- will produce as output two files in the default directory, having the same
- name as the input file but with file types of ".h" and ".cc".
-
-3. Include the .h file in your source code to define message symbols, and
- make sure that the .cc file is compiled and linked into your program -
- static initialization will add the symbols to the global dictionary.
-
-4. Declare loggers in your code and use them to log messages. This is
- described in more detail below.
-
-5. To set the debug level and run-time message file, call initLogger (declared
- in logger_support.h) in the main program unit.
-
-
-Message Files
-=============
-
-File Contents and Format
-------------------------
-A message file is a file containing message definitions. Typically there
-will be one message file for each component that declares message symbols.
-An example file could be:
-
--- BEGIN --
-
-# Example message file
-
-$NAMESPACE isc::log
-
-% LOG_UNRECOGNISED_DIRECTIVE line %1: unrecognised directive '%2'
-A line starting with a dollar symbol was found, but the first word on the line
-(shown in the message) was not a recognised message compiler directive.
-
-% LOG_WRITE_ERROR error writing to %1: %2
-The specified error was encountered by the message compiler when writing to
-the named output file.
-
--- END --
-
-Points to note:
-* Leading and trailing space are trimmed from the line. Although the above
- example has every line starting at column 1, the lines could be indented
- if desired.
-
-* Blank lines are ignored.
-
-* Lines starting with "#" are comments are are ignored. Comments must be on
- a line by themselves - inline comments will be interpreted as part of the
- text of the line.
-
-* Lines starting $ are directives. At present, just one directive is
- recognised:
-
- * $NAMESPACE, which has one argument: the namespace in which the symbols are
- created. In the absence of a $NAMESPACE directive, symbols will be put in
- the anonymous namespace.
-
-* Message lines. These start with a "%" and are followed by the message
- identification and the message text, the latter including zero or more
- replacement tokens, e.g.
-
- % LOG_WRITE_ERROR error writing to %1: %2
-
- * There may be zero or more spaces between the leading "%" and the message
- identification (which, in the example above, is the string
- "LOG_WRITE_ERROR").
-
- * The message identification can be any string of letters, digits and
- underscores, but should not start with a digit. The convention adopted
- in BIND 10 is for the first component (before the first underscore) to be
- a string indicating the origin of the message, and the remainder to
- describe the message. So in the example above, the LOG_ indicates that
- the error originated from the logging library and the "WRITE_ERROR"
- indicates that there was a problem in a write operation.
-
- * The rest of the line - from the first non-space character to the
- last non- space character - is taken exactly for the text
- of the message. There are no restrictions on what characters may
- be in this text, other than they be printable. (This means that
- both single-quote (') and double-quote (") characters are allowed.)
- The message text may include replacement tokens (the strings "%1",
- "%2" etc.). When a message is logged, these are replaced with the
- arguments passed to the logging call: %1 refers to the first argument,
- %2 to the second etc. Within the message text, the placeholders
- can appear in any order and placeholders can be repeated. Otherwise,
- the message is printed unmodified.
-
-* Remaining lines indicate an explanation for the preceding message. These
- are intended to be processed by a separate program and used to generate
- an error messages manual. They are ignored by the message compiler.
-
-Message Compiler
-----------------
-The message compiler is a program built in the src/log/compiler directory.
-It is invoked by the command:
-
- message [-h] [-v] -p] <message-file>
-
-("-v" prints the version number and exits; "-h" prints brief help text.) The
-compiler produces source files for C++ and Python.
-
-C++ Files
----------
-Without the "-p" option, the message compiler processes the message file
-to produce two files:
-
-1) A C++ header file (called <message-file-name>.h) that holds lines of
-the form:
-
- namespace <namespace> {
- extern const isc::log::MessageID LOG_WRITE_ERROR;
- :
- }
-
-The symbols define the keys in the global message dictionary, with the
-namespace enclosing the symbols set by the $NAMESPACE directive.
-
-(This is the reason for the restriction on message identifiers - they
-have to be valid C++ symbol names.)
-
-2) A C++ source file (called <message-file-name>.cc) that holds the definitions
-of the global symbols and code to insert the symbols and messages into the map.
-
-Symbols are defined to be equal to strings holding the identifier, e.g.
-
- extern const isc::log::MessageID LOG_WRITE_ERROR = "LOG_WRITE_ERROR";
-
-(The implementation allows symbols to be compared. However, use of strings
-should not be assumed - a future implementation may change this.)
-
-In addition, the file declares an array of identifiers/messages and an object
-to add them to the global dictionary:
-
- namespace {
- const char* values[] = {
- identifier1, text1,
- identifier2, text2,
- :
- NULL
- };
-
- const isc::log::MessageInitializer initializer(values);
- }
-
-The constructor of the MessageInitializer object retrieves the singleton
-global Dictionary object (created using standard methods to avoid the
-"static initialization fiasco") and adds each identifier and text to it.
-A check is made as each is added; if the identifier already exists, it is
-added to "overflow" vector; the vector is printed to the main logging output
-when logging is finally enabled (to indicate a programming error).
-
-Python Files
-------------
-If the "-p" option is given, the compiler produces a Python module defining
-the messages. The format of this is:
-
-import isc.log
- :
-LOG_WRITE_ERROR = isc.log.create_message("LOG_WRITE_ERROR",
- "error writing to %1 : %2")
-
-(The definition is output on one line - it is split across two lines in this
-document for readability.)
-
-The module can be imported into other Python code, and messages logged
-in a similar way to C++ using the Python logging library.
-
-Using the Logging - C++
-=======================
-1. Build message header file and source file as describe above.
-
-2. The main program unit must include a call to isc::log::initLogger()
- (described in more detail below) to set the logging severity, debug log
- level, and external message file:
-
- a) The logging severity is one of the enum defined in logger.h, i.e.
-
- isc::log::DEBUG
- isc::log::INFO
- isc::log::WARN
- isc::log::ERROR
- isc::log::FATAL
- isc::log::NONE
-
- b) The debug log level is only interpreted when the severity is
- DEBUG and is an integer ranging from 0 to 99. 0 should be used
- for the highest-level debug messages and 99 for the lowest-level
- (and typically more verbose) messages.
-
- c) The external message file. If present, this is the same as a
- standard message file, although it should not include any
- directives. (A single directive of a particular type will be
- ignored; multiple directives will cause the read of the file to
- fail with an error.)
-
- The settings remain in effect until the logging configuration is read,
- and so provide the default logging during program initialization.
-
-3. Declare a logger through which the message will be logged.
-
- isc::log::Logger logger("name");
-
- The string passed to the constructor is the name of the logger (it
- can be any string) and is used when configuring it. Loggers with
- the same name share the same configuration.
-
-4. Issue logging calls using supplied macros in "log/macros.h", e.g.
-
- LOG_ERROR(logger, LOG_WRITE_ERROR).arg("output.txt");
-
- (The macros are more efficient that calls to the methods on the logger
- class: they avoid the overhead of evaluating the parameters to arg()
- if the settings are such that the message is not going to be output.)
-
-Using the Logging - Python
-==========================
-1. Build message module as describe above.
-
-2. The main program unit must include a call to isc.log.init()
- (described in more detail below) to set the to set the logging
- severity, debug log level, and external message file:
-
- a) The logging severity is one of the strings:
-
- DEBUG
- INFO
- WARN
- ERROR
- FATAL
- NONE
-
- b) The debug log level is only interpreted when the severity is
- DEBUG and is an integer ranging from 0 to 99. 0 should be used
- for the highest-level debug messages and 99 for the lowest-level
- (and typically more verbose) messages.
-
- c) The external message file. If present, this is the same as a
- standard message file, although it should not include any
- directives. (Any that are there will be ignored.)
-
- The settings remain in effect until the logging configuration is read,
- and so provide the default logging during program initialization.
-
-3. Declare a logger through which the message will be logged.
-
- isc.log.Logger logger("name")
-
- The string passed to the constructor is the name of the logger (it
- can be any string) and is used when configuring it. Loggers with
- the same name share the same configuration.
-
-4. Issue calls to the logging methods:
-
- logger.error(LOG_WRITE_ERROR, "output.txt");
-
-Logging Initialization
-======================
-In all cases, if an attempt is made to use a logging method before the logging
-has been initialized, the program will terminate with a LoggingNotInitialized
-exception.
-
-C++
----
-Logging Initialization is carried out by calling initLogger(). There are two
-variants to the call, one for use by production programs and one for use by
-unit tests.
-
-Variant #1, Used by Production Programs
----------------------------------------
-void isc::log::initLogger(const std::string& root,
- isc::log::Severity severity = isc::log::INFO,
- int dbglevel = 0, const char* file = NULL,
- bool buffer = false);
-
-This is the call that should be used by production programs:
-
-root
-Name of the program (e.g. "b10-auth"). This is also the name of the root
-logger and is used when configuring logging.
-
-severity
-Default severity that the program will start logging with. Although this may
-be overridden when the program obtains its configuration from the configuration
-database, this is the severity that it used until then. (This may be set by
-a command-line parameter.)
-
-dbglevel
-The debug level used if "severity" is set to isc::log::DEBUG.
-
-file
-The name of a local message file. This will be read and its definitions used
-to replace the compiled-in text of the messages.
-
-buffer
-If set to true, initial log messages will be internally buffered, until the
-first time a logger specification is processed. This way the program can
-use logging before even processing its logging configuration. As soon as any
-specification is processed (even an empty one), the buffered log messages will
-be flushed according to the specification. Note that if this option is used,
-the program SHOULD call one of the LoggerManager's process() calls (if you
-are using the built-in logging configuration handling in ModuleCCSession,
-this is automatically handled). If the program exits before this is done,
-all log messages are dumped in a raw format to stdout (so that no messages
-get lost).
-
-Variant #2, Used by Unit Tests
-------------------------------
- void isc::log::initLogger()
-
-This is the call that should be used by unit tests. In this variant, all the
-options are supplied by environment variables. (It should not be used for
-production programs to avoid the chance that the program operation is affected
-by inadvertently-defined environment variables.)
-
-The environment variables are:
-
-B10_LOGGER_ROOT
-Sets the "root" for the unit test. If not defined, the name "bind10" is used.
-
-B10_LOGGER_SEVERITY
-The severity to set for the root logger in the unit test. Valid values are
-"DEBUG", "INFO", "WARN", "ERROR", "FATAL" and "NONE". If not defined, "INFO"
-is used.
-
-B10_LOGGER_DBGLEVEL
-If B10_LOGGER_SEVERITY is set to "DEBUG", the debug level. This can be a
-number between 0 and 99, and defaults to 0.
-
-B10_LOGGER_LOCALMSG
-If defined, points to a local message file. The default is not to use a local
-message file.
-
-B10_LOGGER_DESTINATION
-The location to which log message are written. This can be one of:
-
- stdout Message are written to stdout
- stderr Messages are written to stderr
- syslog[:facility] Messages are written to syslog. If the optional
- "facility" is used, the messages are written using
- that facility. (This defaults to "local0" if not
- specified.)
- Anything else Interpreted as the name of a file to which output
- is appended. If the file does not exist, a new one
- is opened.
-
-In the case of "stdout", "stderr" and "syslog", they must be written exactly
-as is - no leading or trailing spaces, and in lower-case.

-Severity Guidelines
-===================
-When using logging, the question arises, what severity should a message
-be logged at? The following is a suggestion - as always, the decision
-must be made in the context of which the message is logged.
-
-One thing that should always be borne in mind is whether the logging
-could be used as a vector for a DOS attack. For example, if a warning
-message is logged every time an invalid packet is received, an attacker
-could simply send large numbers of invalid packets. (Of course, warnings
-could be disabled (or just warnings for that that particular logger),
-but nevertheless the message is an attack vector.)
-
-FATAL
------
-The program has encountered an error that is so severe that it cannot
-continue (or there is no point in continuing). When a fatal error
-has been logged, the program will usually exit immediately (or shortly
-afterwards) after dumping some diagnostic information.
-
-ERROR
------
-Something has happened such that the program can continue but the
-results for the current (or future) operations cannot be guaranteed to
-be correct, or the results will be correct but the service is impaired.
-For example, the program started but attempts to open one or more network
-interfaces failed.
-
-WARN
-----
-An unusual event happened. Although the program will continue working
-normally, the event was sufficiently out of the ordinary to warrant
-drawing attention to it. For example, at program start-up a zone was
-loaded that contained no resource records,
-
-INFO
-----
-A normal but significant event has occurred that should be recorded,
-e.g. the program has started or is just about to terminate, a new zone
-has been created, etc.
-
-DEBUG
------
-This severity is only enabled on for debugging purposes. A debug level is
-associated with debug messages, level 0 (the default) being for high-level
-messages and level 99 (the maximum) for the lowest level. How the
-messages are distributed between the levels is up to the developer.
-So if debugging the NSAS (for example), a level 0 message might record
-the creation of a new zone, a level 10 recording a timeout when trying
-to get a nameserver address, but a level 50 would record every query for
-an address. (And we might add level 70 to record every update of the RTT.)
-
-Note that like severities, levels are cumulative; so if level 25 is
-set as the debug level, all debug levels from 0 to 25 will be output.
-In fact, it is probably easier to visualise the debug levels as part of
-the severity system:
-
- FATAL High
- ERROR
- WARN
- INFO
- DEBUG level 0
- DEBUG level 1
- :
- DEBUG level 99 Low
-
-When a particular severity is set, it - and all severities and/or debug
-levels above it - will be logged.
-
-To try to ensure that the information from different modules is roughly
-comparable for the same debug level, a set of standard debug levels has
-been defined for common type of debug output. However, modules are free
-to set their own debug levels or define additional ones.
-
-Logging Sources v Logging Severities
-------------------------------------
-When logging events, make a distinction between events related to the
-server and events related to DNS messages received. Caution needs to
-be exercised with the latter as, if the logging is enabled in the normal
-course of events, such logging could be a denial of service vector. For
-example, suppose that the main authoritative service logger were to
-log both zone loading and unloading as INFO and a warning message if
-it received an invalid packet. An attacker could make the INFO messages
-unusable by flooding the server with malformed packets.
-
-There are two approaches to get round this:
-
-a) Make the logging of packet-dependent events a DEBUG-severity message.
-DEBUG is not enabled by default, so these events will not be recorded
-unless DEBUG is specifically chosen.
-
-b) Record system-related and packet-related messages via different loggers
-(e.g. in the example given, server events could be logged using the
-logger "auth" and packet-related events at that level logged using the
-logger "pkt-auth".) As the loggers are independent and the severity
-levels independent, fine-tuning of what and what is not recorded can
-be achieved.
-
-
-Notes
-=====
-The message compiler is written in C++ (instead of Python) because it
-contains a component that reads the message file. This component is used
-in both the message compiler and the server; in the server it is used
-when the server starts up (or when triggered by a command) to read in
-a message file to overwrite the internal dictionary. Writing it in C++
-means there is only one piece of code that does this functionality.

+ at page logBind10Logging BIND 10 Logging
+
+ at section logBasicIdeas Basic Ideas
+
+The BIND 10 logging system is based on the log4J logging system
+common in Java development, and includes the following ideas:
+
+- A set of severity levels.
+- A hierarchy of logging sources.
+- Separation of message use from message text.
+
+ at subsection logSeverity Message Severity
+Each message logged by BIND 10 has a severity associated with it, ranging
+from FATAL - the most severe - to DEBUG - messages output as the code
+executes to facilitate debugging. In order of decreasing severity,
+the levels are:
+
+<dl>
+<dt>FATAL</dt>
+<dd>The program has encountered an error that is so severe that it
+cannot continue (or there is no point in continuing). For example, an
+unhandled exception generated deep within the code has been caught by the
+top-level program. When a fatal error has been logged, the program will
+exit immediately (or shortly afterwards) after dumping some diagnostic
+information.</dd>
+
+<dt>ERROR</dt>
+<dd>Something has happened such that the program can continue but the
+results for the current (or future) operations cannot be guaranteed to
+be correct, or the results will be correct but the service is impaired.
+For example, the program started but attempts to open one or more network
+interfaces failed.</dd>
+
+<dt>WARN</dt>
+<dd>(Warning) An unusual event happened. Although the program will
+continue working normally, the event was sufficiently out of the ordinary
+to warrant drawing attention to it. For example, the authoritative
+server loaded a zone that contained no resource records.</dd>
+
+<dt>INFO</dt>
+<dd>(Information) A normal but significant event has occurred that should
+be recorded, e.g. the program has started or is just about to terminate,
+a new zone has been created, etc.</dd>
+
+<dt>DEBUG</dt>
+<dd>Debug messages are output at this severity. Each message also
+has a debug level associated with it, ranging from 0 (the default)
+for high-level messages and level 99 (the maximum) for the the lowest
+level.</dd>
+</dl>
+
+When logging is enabled for a component, it is enabled for a particular
+severity level and all higher severities. So if logging is enabled
+for INFO messages, WARN, ERROR and FATAL messages will also be logged,
+but not DEBUG ones. If enabled for ERROR, only ERROR and FATAL messages
+will be logged.
+
+As noted above, DEBUG messages are also associated with a debug level.
+This allows the developer to control the amount of debugging information
+produced; the higher the debug level, the more information is output.
+For example, if debugging the NSAS (nameserver address store), debug
+levels might be assigned as follows: a level 0 debug message records
+the creation of a new zone, a level 10 logs every timeout when trying
+to get a nameserver address, a level of 50 records every query for an
+address and a level of 70 records every update of the round-trip time.
+
+Like severities, levels are cumulative; so if level 25 is set as the
+debug level, all debug messages associated levels 0 to 25 (inclusive)
+will be output. In fact, it is probably easier to visualise the debug
+levels as part of the severity system:
+ at code
+FATAL Most severe
+ERROR
+WARN
+INFO
+DEBUG level 0
+DEBUG level 1
+ :
+DEBUG level 99 Least severe
+ at endcode
+When a particular debug level is set, it - and all debug levels and
+severities above it - will be logged.
+
+To try to ensure that the information from different modules is roughly
+comparable for the same debug level, a set of standard debug levels has
+been defined for common types of debug output. (These can be found in
+ at ref log_dbglevels.h) However, modules are free to set their own debug
+levels or define additional ones.
+
+ at subsection logHierarchical Hierarchical Logging System
+
+When a program writes a message to the logging system, it does so using an
+instance of the @ref isc::log::Logger class. As well as performing the
+write of the message, the logger identifies the source of the message:
+different sources can write to different destinations and can log
+different severities of messages. For example, the logger associated
+with the resolver's cache code could write debugging and other messages
+to a file while all other components only write messages relating to
+errors to the syslog file.
+
+The loggers are hierarchical in that each logger is the child of another
+logger. The top of the hierarchy is the root logger; this does not
+have a parent. The reason for this hierarchy is that unless a logger
+explicitly assigns a value to an attribute (such as severity of messages
+it should log), it picks it up the value from the parent. In BIND 10,
+each component (b10-auth, b10-resolver etc.) has a root logger (named
+after the program) and every other logger in the component is a child
+of that. So in the example above, the error/syslog attributes could be
+associated with the b10-resolver logger while the logger associated with
+the cache sets its own values for the debug/file attributes.
+
+More information about the logging hierarchy can be found in the section
+on Logging configuration in the <a
+href="http://bind10.isc.org/docs/bind10-guide.html#logging">BIND 10
+Guide</a>.
+
+ at subsection logSeparationUseText Separation of Messages Use from Message Text
+
+Separating the use of the message from the text associated with it -
+in essence, defining message text in an external file - allows for the
+replacement the supplied text of the messages with a local language version.
+It also means that other attributes can be associated with the message,
+for example, an explanation of the meaning of the message and other
+information such as remedial action in the case of errors.
+
+Each message has an identifier such as "LOG_WRITE_ERROR".
+Within the program, this is the symbol passed to the logging system
+which uses the symbol as an index into a dictionary to retrieve the message
+associated with it (e.g. "unable to open %1 for input"), after which it
+substitutes any message parameters (in this example, the name of the file
+where the write operation failed) and logs the result to the destination.
+
+In BIND 10, a the default text for each message is linked into the
+program. Each program is able to read a locally-defined message file
+when it starts, updating the stored definitions with site-specific text.
+When the message is logged, the updated text is output. However, the
+message identifier is always included in the output so that the origin
+of the message can be identified even if the text has been changed.
+
+ at note Local message files have not yet been implemented in BIND 10.
+
+
+
+ at section logDeveloperUse Using Logging in a BIND 10 Component
+
+The steps in using the logging system in a BIND 10 component (such as
+an executable or library) are:
+
+<ol>
+<li>Create a message file. This defines messages by an identification
+string and and text that explains the message in more detail. Ideally the
+file should have a file type of ".mes".</li>
+
+<li>Run it through the message compiler to produce the files for your
+module. This step should be included in the build process. The message
+compiler is a BIND10 program and is one of the first programs built and
+linked in the build process. As a result, it should be available for
+compiling the message files of all BIND 10 components and libraries.
+
+For C++ development, the message compiler produces two files in the
+default directory, having the same name as the input file but with file
+types of ".h" and ".cc". For Python, the message compiler will produce
+a Python module containing the symbols.</li>
+
+<li>Include the resultant files in your source code to define message symbols,
+and (for C++) compile the code and link it into your program.</li>
+
+<li>Declare loggers in your code and use them to log messages.</li>
+
+<li>Call the logger initialization function in the program's main module.</li>
+
+</ol>
+
+The following sections describe these steps in more detail.
+
+
+ at subsection logMessageFiles Create a Message File
+
+A message file contains message definitions. Typically there
+will be one message file for each component that uses BIND 10 logging.
+An example file could be:
+
+ at code
+# Example message file
+
+$NAMESPACE isc::log
+
+% LOG_UNRECOGNISED_DIRECTIVE line %1: unrecognised directive '%2'
+A line starting with a dollar symbol was found, but the first word on the line
+(shown in the message) was not a recognised message compiler directive.
+
+% LOG_WRITE_ERROR error writing to %1: %2
+The specified error was encountered by the message compiler when writing to
+the named output file.
+ at endcode
+
+Points to note are:
+
+<ul>
+<li>Leading and trailing spaces are trimmed from each line before it
+is processed. Although the above example has every line starting at
+column 1, the lines could be indented if desired.</li>
+
+<li>Lines starting with "#" are comments are are ignored. Comments must
+be on a line by themselves; inline comments will be interpreted as part
+of the text of that line.</li>
+
+<li>Lines starting with "$" are directives. At present, just one
+directive is recognised:
+ <dl>
+ <dt>$NAMESPACE <namespace-name></dt>
+ <dd>The sole argument is the name of the namespace in which the
+ symbols are created. In the absence of a $NAMESPACE directive,
+ symbols will be put in the anonymous namespace.</dd>
+ </dl>
+</li>
+
+<li>Lines starting with "%" are message definitions and comprise the message
+identification and the message text. For example:
+ at code
+% LOG_WRITE_ERROR error writing to %1: %2
+ at endcode
+
+There may be zero or more spaces between the leading "%" and the
+message identification (which, in the example above, is the string
+"LOG_WRITE_ERROR").</li>
+
+<li>The message identification can be any string of letters, digits and
+underscores, but must not start with a digit.</li>
+
+<li>The rest of the line - from the first non-space character to the
+last non- space character - is the text of the message. There are no
+restrictions on what characters may be in this text, other than they be
+printable (so both single-quote (') and double-quote (") characters are
+allowed). The message text may include replacement tokens (the strings
+"%1", "%2" etc.). When a message is logged, these are replaced with the
+arguments passed to the logging call: %1 refers to the first argument,
+%2 to the second etc. Within the message text, the placeholders can
+appear in any order and placeholders can be repeated. Otherwise, the
+message is printed unmodified.</li>
+
+<li>Remaining lines indicate an explanation for the preceding message.
+The explanation can comprise multiple paragraphs, the paragraphs being
+separated by blank lines. These lines are intended to be processed by a
+separate program to generate an error messages manual; they are ignored
+by the message compiler.</li>
+
+<li>Except when used to separate paragraphs in the message explanation,
+blank lines are ignored.</li>
+</ul>
+
+Although there are few restriction on what can be in the message
+identifcation and text, there are a number of conventions used by BIND
+10, both in the contents of the message and in the usage. All code
+should adhere to these:
+
+<ul>
+<li>Message identifications should include at least one underscore.
+The component before the first underscore is a string indicating the
+origin of the message, and the remainder describes the condition.
+So in the example above, the LOG indicates that the error originated
+from the logging library and the "WRITE_ERROR" indicates that there was
+a problem in a write operation.</li>
+
+<li>The part of the message identification describing the error (e.g.
+"WRITE_ERROR" in the example above) should comprise no more than
+two or three words separated by underscores. An excessive number
+of words or overly long message identification should be avoided;
+such information should be put in the text of the message. For example,
+"RESOLVER_ERROR_FETCHING_NAME_FROM_UPSTREAM_SERVER" is excessively long,
+"RESOLVER_FETCH_ERROR" being better.</li>
+
+<li>Similarly, the text of the message should be reasonably concise. It should
+include enough information (possibly supplied at run-time in the form of
+parameters) to allow further investigations to be undertaken if required.
+
+Taking the above example, a suitable error message to indicate that the
+resolver has failed to read a name from an upstream authoritative server
+could be:
+
+ at code
+% RESOLVER_FETCH_ERROR fetch from %1 failed, error code %2 (%3)
+ at endcode
+
+... where %1 indicates the name or IP address of the server to which the
+fetch was sent, %2 the errno value returned and %3 the message associated
+with that error number (retrieved via a call to "strerror()").
+
+</li>
+
+<li>The message should not have a comma after the message identification.
+The message text should neither start with a capital letter (unless
+the first word is a proper noun or is normally written in capitals)
+nor end with a period. The message reporting system takes care of such
+punctuation.</li>
+
+<li>The parameters substituted into the message text should not include
+line breaks. Messages are normally output to the syslog file which
+has the inbuilt assumption of one line per message. Splitting a message
+across multiple lines makes it awkward to search the file for messages
+and associated information.</li>
+
+<li>The message identifier should be unique across the entire BIND 10
+system. (An error will be reported at system start-up if an identifier
+is repeated.)</li>
+
+<li>A particular message identifier should only be used at one place in
+the BIND 10 code. In this way, if the message indicates a problem, the
+code in question can be quickly identified.</li>
+
+<li>The explanation of the message - the free-form text following the
+message identification - appears in the BIND 10 message manual. It
+should:
+
+<ul>
+<li>Describe the serverity of the message (debug, informational etc.)</li>
+
+<li>Expand on the text of the message. In some cases, such as
+debug messages, the message text may provide more or less sufficient
+description. For warnings and errors, the explanation should provide
+sufficient background to the problem to allow a non-developer to
+understand the issue and to begin fault-finding. If possible, the
+explanation should also include suggested remedial action.</li>
+</ul>
+</ul>
+
+ at subsection logSourceFiles Produce Source Files
+The message file created in the previous step is then run through the
+message compiler to produce source files that are included in the BIND
+10 programs.
+
+ at subsubsection logMessageCompiler Message Compiler
+The message compiler is a program built in the src/log/compiler directory.
+It is invoked by the command:
+ at code
+message [-h] [-v] [-p] [-d dir] <message-file>
+ at endcode
+"-v" prints the version number and exits; "-h" prints brief help text.
+The compiler produces source files for C++ unless the "-p" switch is
+specified, in which case it produces Python code. Finally, the "-d"
+switch directs the compiler to produce the output files in the specified
+directory (the default being the current working directory).
+
+<b>C++ Files</b><br/>
+Without the "-p" option, the message compiler processes the message file
+to produce two files:
+
+<ol>
+<li>A C++ header file (called <message-file-name>.h) holding lines of
+the form:
+ at code
+namespace <namespace-name> {
+ extern const isc::log::MessageID LOG_BAD_DESTINATION;
+ extern const isc::log::MessageID LOG_BAD_SEVERITY;
+ :
+}
+ at endcode
+The symbols define keys in the global message dictionary, with
+the namespace enclosing the symbols set by the $NAMESPACE directive.
+(This is the reason for the restriction on message identifiers - they
+have to be valid C++ symbol names.)</li>
+
+<li>A C++ source file (called <message-file-name>.cc) that holds the definitions
+of the global symbols and code to insert the symbols and messages into
+an internal dictionary.
+
+Symbols are defined to be equal to strings equal to the identifier, e.g.
+ at code
+extern const isc::log::MessageID LOG_BAD_DESTINATION = "LOG_BAD_DESTINATION";
+extern const isc::log::MessageID LOG_BAD_SEVERITY = "LOG_BAD_SEVERITY";
+ :
+ at endcode
+(The current implementation allows symbols to be compared. However,
+use of strings should not be assumed - a future implementation may change
+this.) In addition, the file declares an array of identifiers/messages
+and an object to add them to the global dictionary, e.g.:
+ at code
+namespace {
+ const char* values[] = {
+ "LOG_BAD_DESTINATION", "unrecognized log destination: %1",
+ "LOG_BAD_SEVERITY", "unrecognized log severity: %1",
+ :
+ NULL
+ };
+ const isc::log::MessageInitializer initializer(values);
+}
+ at endcode
+
+The constructor of the @ref isc::log::MessageInitializer object retrieves
+the singleton global @ref isc::log::MessageDictionary object (created
+using standard methods to avoid the "static initialization fiasco") and
+adds each identifier and associated text to it. These constructors are run
+when the program starts; a check is made as each identifier is added and,
+if the identifier already exists in the dictionary, a warning message
+is printed to the main logging output when logging is finally enabled.
+The appearance of such a message indicates a programming error.
+</li>
+</ol>
+
+<b>Python Files</b><br/>
+If the "-p" option is given, the compiler produces a Python module defining
+the messages. The content of this is of the form:
+ at code
+import isc.log
+ :
+LOG_WRITE_ERROR = isc.log.create_message("LOG_WRITE_ERROR",
+ "error writing to %1 : %2")
+ at endcode
+(The definition is output on one line - it is split across two lines in this
+document for readability.)
+
+The module can be imported into other Python code, and messages logged
+in a similar way to C++ using the Python logging library.
+
+ at subsubsection logMakefile Include Message Compilation in Makefile
+The source file for the messages is the ".mes" file, but the files used
+by the code (which, in the case of C++, must be compiled and linked)
+are the output of the message compiler. (The compiler is produced very
+early on in the BIND 10 build sequence, so is available for use in the
+building of subsequent components.) To allow this, certain dependencies
+must be included in the Makefile.am for each component that uses logging.
+
+<b>Including Message files in C++ Component Builds</b><br/>
+The following segment from the "hooks" Makefile.am illustrates
+the entries needed.
+ at code
+# Define rule to build logging source files from message file
+hooks_messages.h hooks_messages.cc: s-messages
+
+s-messages: hooks_messages.mes
+ $(top_builddir)/src/lib/log/compiler/message $(top_srcdir)/src/lib/hooks/hooks_messages.mes
+ touch $@
+
+# Tell automake that the message files are built as part of the build process
+# (so that they are built before the main library is built).
+BUILT_SOURCES = hooks_messages.h hooks_messages.cc
+
+# Ensure that the message file is included in the distribution
+EXTRA_DIST = hooks_messages.mes
+
+# Get rid of generated message files on a clean
+CLEANFILES = *.gcno *.gcda hooks_messages.h hooks_messages.cc s-messages
+ at endcode
+The first two rules relate the output .h and .cc files produced by the
+message compiler to the input .mes file. The intermediate "s-messages"
+file is used to overcome synchronization issues with parallel builds
+(where "make" uses multiple processes running in parallel). Note that the
+reference to both the compiler and the input message file are via absolute
+paths defined in terms of Automake macros. In particular it is important
+that the message compiler - which is created during the build process - is
+referred to via the "top_builddir" macro, whereas the input message file -
+which is in the repository - is accessed through the "top_srcdir" macro.
+
+The BUILT_SOURCES line notifies the Automake that the .h and .cc files
+need to be created before they can be used in the compilation, so
+instructs it to organse things so that the message compiler is run first.
+
+As the .mes file is not directly included in any compilation, it will
+not be automatically copied into a distribution created through this
+Makefile.am. The EXTRA_DIST line informs Automake that this file does
+need to be included.
+
+Finally, the intermediate files - the .cc and .h file, as well as the
+intermediate s-messages file - need to be removed when "make clean" is run.
+These files are therefore included in the definition of the CLEANFILES macro.
+
+Not shown are the Makefile.am lines where the .h and .cc file are used. These
+are the same as other lines specifying .h and .cc source files.
+
+<b>Including Message files in Python Component Builds</b><br/>
+The following (modified) segments from the "xfrin" Makefile.am illustrates
+the entries needed.
+
+ at code
+CLEANFILES = $(PYTHON_LOGMSGPKG_DIR)/work/xfrin_messages.py
+CLEANFILES += $(PYTHON_LOGMSGPKG_DIR)/work/xfrin_messages.pyc
+ :
+EXTRA_DIST += xfrin_messages.mes
+ :
+# Define rule to build logging source files from message file
+$(PYTHON_LOGMSGPKG_DIR)/work/xfrin_messages.py : xfrin_messages.mes
+ $(top_builddir)/src/lib/log/compiler/message \
+ -d $(PYTHON_LOGMSGPKG_DIR)/work -p $(srcdir)/xfrin_messages.mes
+ at endcode
+The CLEANFILES lines remove the created Python (and compiled Python)
+code when "make clean" is run.
+
+The EXTRA_DIST line ensures that the .mes file is copied to the
+distribution tarball.
+
+The final dependency shows the use of the message compiler to
+create the Python message module in a working directory.
+
+
+ at subsection logUsage Using Logging Files in Program Development
+
+ at subsubsection logCppUsage Use in a C++ Program or Module
+To use logging in a C++ program or module:
+
+<ol>
+<li>Build the message header file and source file as described above.</li>
+
+<li>In each C++ file in which logging is to be used, declare a logger
+through which the message will be logged.
+
+ at code
+isc::log::Logger logger("name");
+ at endcode
+This declaration can be per-function, or it can be declared statically
+in file scope. The string passed to the constructor is the name of
+the logger (it can be any string) and is used when configuring it.
+(Remember though that the name of root logger for the program will be
+prepended to the name chosen. So if, for example, the name "cache"
+is chosen and the model is included in the "b10-resolver" program, the
+full name of the logger will be "b10-resolver.cache".) Loggers with
+the same name share the same configuration. For this reason if, as is
+usual, messages logged in different files in the same component (e.g.
+hooks module, nameserver address store, etc.) originate from loggers
+with the same name, the logger declaration can be placed into a header
+file.</li>
+
+<li>Issue logging calls using supplied macros in "log/macros.h", e.g.
+ at code
+LOG_ERROR(logger, LOG_WRITE_ERROR).arg("output.txt");
+LOG_DEBUG(nsas_logger, NSAS_DBG_TRACE, NSAS_LOOKUP_CANCEL).arg(zone);
+ at endcode
+All macros (with the exception of LOG_DEBUG) take two arguments:
+the C++ logger object that will be used to log the message, and the
+identification of the message to be logged. LOG_DEBUG takes three
+arguments, the additional one being the debug level associated with
+the message. The .arg() call appended to the end of the LOG_XXX()
+macro handles the arguments to the message. A chain of these is used
+in cases where a message takes multiple arguments, e.g.
+ at code
+LOG_DEBUG(nsas_logger, NSAS_DBG_RTT, NSAS_UPDATE_RTT)
+ .arg(addresses_[family][index].getAddress().toText())
+ .arg(old_rtt).arg(new_rtt);
+ at endcode
+Using the macros is more efficient than direct calls to the methods on
+the logger class: they avoid the overhead of evaluating the parameters
+to arg() if the logging settings are such that the message is not going
+to be output (e.g. it is a DEBUG message and the logging is set to output
+messages of INFO severity or above).</li>
+
+<li>The main program unit must include a call to isc::log::initLogger()
+(described in more detail below) to set the initial logging severity, debug log
+level, and external message file.
+</ol>
+
+ at subsubsection logPythonUsage Use in a Python Module
+To use logging in a Python module:
+<ol>
+<li>Build message module as described above.</li>
+
+<li>Declare a logger through which the message will be logged.
+ at code
+isc.log.Logger logger("name")
+ at endcode
+The string passed to the constructor is the name of the logger (it can
+be any string) and is used when configuring it. Loggers with the same
+name share the same configuration.</li>
+
+<li>Issue calls to the logging methods:
+ at code
+logger.error(LOG_WRITE_ERROR, "output.txt")
+ at endcode
+The message parameters are included as trailing arguments in the
+logger call.</li>
+
+<li>The main program unit must include a call to isc.log.init() (described
+in more detail below) to set the to set the logging severity, debug log
+level, and external message file. The settings remain in effect until
+the logging configuration is read, so are the ones used during program
+initialization.</li>
+</ol>
+
+
+ at subsection logInitialization Logging Initialization
+In all cases, if an attempt is made to use a logging method before
+the logging has been initialized, the program will terminate with a
+LoggingNotInitialized exception.
+
+ at subsection logInitializationCpp C++ Initialization
+Logging Initialization is carried out by calling @ref
+isc::log::initLogger(). There are two variants to the call, one for
+use by production programs and one for use by unit tests.
+
+ at subsubsection logInitializationCppVariant1 Variant #1, Used by Production Programs
+The call that should be used by all production programs is:
+ at code
+void isc::log::initLogger(const std::string& root,
+ isc::log::Severity severity = isc::log::INFO,
+ int dbglevel = 0, const char* file = NULL,
+ bool buffer = false);
+ at endcode
+Arguments are:
+<dl>
+<dt><code>root</code></dt>
+<dd>Name of the root logger. This should be the name of the program
+(e.g. "b10-auth") and is used when configuring logging.</dd>
+
+<dt><code>severity</code></dt>
+<dd>Default severity that the program will start logging with. Although
+this may be overridden when the program obtains its configuration from
+the configuration database, this is the severity that it used until then.
+The logging severity is one of the enum defined in @ref logger.h, i.e.
+
+ at code
+isc::log::DEBUG
+isc::log::INFO
+isc::log::WARN
+isc::log::ERROR
+isc::log::FATAL
+isc::log::NONE
+ at endcode
+
+(The level NONE may be used to disable logging.)
+</dd>
+
+<dt><code>dbglevel</code></dt>
+<dd>The debug log level is only interpreted when the severity is
+isc::log::DEBUG and is an integer ranging from 0 to 99. 0 should be
+used for the highest-level debug messages and 99 for the lowest-level
+(and typically more verbose) messages.</dd>
+
+<dt><code>file</code></dt>
+<dd>The name of a local message file. This will be read and its
+definitions used to replace the compiled-in text of the messages.
+The default value of NULL indicates that no local message file is
+supplied.</dd>
+
+<dt><code>buffer</code></dt>
+<dd>If set to true, initial log messages will be internally buffered,
+until the first time a logger specification is processed. This
+way the program can use logging before even processing its logging
+configuration. As soon as any specification is processed (even an
+empty one), the buffered log messages will be flushed according to
+the specification. Note that if this option is used, the program
+SHOULD call one of the @ref isc::log::LoggerManager::process() calls.
+(If you are using the built-in logging configuration handling in @ref
+isc::config::ModuleCCSession, this is automatically handled.) If the
+program exits before this is done, all log messages are dumped in a raw
+format to stdout (so that no messages get lost).</dd>
+</dl>
+
+ at subsubsection logInitializationCppVariant2 Variant #2, Used by Unit Tests
+ at code
+void isc::log::initLogger()
+ at endcode
+This is the call that should be used by unit tests. In this variant,
+all the options are supplied by environment variables: it should not
+be used for production programs to avoid the chance that the program
+operation is affected by inadvertently-defined environment variables. The
+environment variables are:
+
+<dl>
+<dt>B10_LOGGER_ROOT</dt>
+<dd>Sets the "root" for the unit test. If not defined, the name "bind10"
+is used.</dd>
+
+<dt>B10_LOGGER_SEVERITY</dt>
+<dd>The severity to set for the root logger in the unit test.
+Valid values are "DEBUG", "INFO", "WARN", "ERROR", "FATAL" and "NONE".
+If not defined, "INFO" is used.</dd>
+
+<dt>B10_LOGGER_DBGLEVEL</dt>
+<dd>If B10_LOGGER_SEVERITY is set to "DEBUG", the debug level. This can
+be a number between 0 and 99, and defaults to 0.</dd>
+
+<dt>B10_LOGGER_LOCALMSG</dt>
+<dd>If defined, points to a local message file. The default is not to
+use a local message file.</dd>
+
+<dt>B10_LOGGER_DESTINATION</dt>
+<dd>The location to which log message are written. This can be one of:
+<ul>
+<li><b>stdout</b> Message are written to stdout.</li>
+<li><b>stderr</b> Messages are written to stderr.</li>
+<li><b>syslog[:facility]</b> Messages are written to syslog. If the
+optional "facility" is used, the messages are written using that facility.
+(This defaults to "local0" if not specified.)</li>
+<li><b>Anything else</b> Interpreted as the name of a file to which
+output is appended. If the file does not exist, a new one is opened.</li>
+</ul>
+In the case of "stdout", "stderr" and "syslog", they must be written exactly
+as is - no leading or trailing spaces, and in lower-case.</dd>
+</dl>
+
+ at subsection logInitializationPython Python Initialization
+To initialize the logger in a Python program, the "init" method must be
+called:
+ at code
+isc.log.init(name, severity, debuglevel, file, buffer)
+ at endcode
+
+<dl>
+<dt><code>name</code></dt>
+<dd>String giving the name of the root logger. This is the only mandatory
+argument, the rest are optional.</dd>
+
+<dt><code>severity</code></dt>
+<dd>The severity, and is one of the strings "DEBUG", INFO" etc.
+The default is "INFO".</dd>
+
+<dt><code>debuglevel</code></dt>
+<dd>Debug level, an integer between 0 and 99. A default value of 0 will
+be used if this is not specified.</dd>
+
+<dt><code>file</code></dt>
+<dd>Name of the external message file (if present). By default, no
+external message file is used.</dd>
+
+<dt><code>buffer</code></dt>
+<dd>If set to true, initial log messages will be internally buffered,
+until the first time a logger specification is processed. This
+way the program can use logging before even processing its logging
+configuration. By default, no buffer is used.</dd>
+</dl>
+
+
+ at section logNotes Notes on the Use of Logging
+One thing that should always be kept in mind is whether the logging
+could be used as a means for a DOS attack. For example, if a warning
+message is logged every time an invalid packet is received, an attacker
+could simply send large numbers of invalid packets. Of course, warnings
+could be disabled (or just warnings for that that particular logger),
+but nevertheless the message is an attack vector. As a general rule,
+if the message can be triggered by a user action, it can be used as an
+attack vector.
+
+There are two approaches to get round this:
+<ol>
+<li>Log messages generated by such user actions as DEBUG messages. DEBUG
+is not enabled by default, so these events will not be recorded unless
+DEBUG is specifically enabled. Choosing a suitable debug level for
+such messages will select only those messages and not the more general
+debug messages.</li>
+
+<li>Record system-related and packet-related messages via different
+loggers. As the loggers are independent and the severity levels
+independent, fine-tuning of what and what is not recorded can be achieved.</li>
+
+</ol>
