New Revision: 289962

URL: http://svn.apache.org/viewcvs?rev=289962&view=rev
Log:
Completed basic directory-backed record serving (DIRDNS-1):
o  Replaced hard-coded A-record serving with hashed adapter mapping record types to their respective encoders.
o  Added encoders for SOA, A, NS, MX, PTR, and CNAME resource records.

+ * 3. The DNAME Resource Record
+ * 
+ *    The DNAME RR has mnemonic DNAME and type code 39 (decimal).
+ * 
+ *    DNAME has the following format:
+ * 
+ *       <owner> <ttl> <class> DNAME <target>
+ * 
+ *    The format is not class-sensitive.  All fields are required.  The
+ *    RDATA field <target> is a <domain-name> [DNSIS].
+ * 
+ *    The DNAME RR causes type NS additional section processing.
+ * 
+ *    The effect of the DNAME record is the substitution of the record's
+ *    <target> for its <owner> as a suffix of a domain name.  A "no-
+ *    descendants" limitation governs the use of DNAMEs in a zone file:
+ * 
+ *       If a DNAME RR is present at a node N, there may be other data at N
+ *       (except a CNAME or another DNAME), but there MUST be no data at
+ *       any descendant of N.  This restriction applies only to records of
+ *       the same class as the DNAME record.
+ * 
+ *    This rule assures predictable results when a DNAME record is cached
+ *    by a server which is not authoritative for the record's zone.  It
+ *    MUST be enforced when authoritative zone data is loaded.  Together
+ *    with the rules for DNS zone authority [DNSCLR] it implies that DNAME
+ *    and NS records can only coexist at the top of a zone which has only
+ *    one node.
+ * 
+ *    The compression scheme of [DNSIS] MUST NOT be applied to the RDATA
+ *    portion of a DNAME record unless the sending server has some way of
+ *    knowing that the receiver understands the DNAME record format.
+ *    Signalling such understanding is expected to be the subject of future
+ *    DNS Extensions.
+ * 
+ *    Naming loops can be created with DNAME records or a combination of
+ *    DNAME and CNAME records, just as they can with CNAME records alone.
+ *    Resolvers, including resolvers embedded in DNS servers, MUST limit
+ *    the resources they devote to any query.  Implementors should note,
+ *    however, that fairly lengthy chains of DNAME records may be valid.

+ * 2. New resource record definition and domain
+ * 
+ *    A record type is defined to store a host's IPv6 address.  A host that
+ *    has more than one IPv6 address must have more than one such record.
+ * 
+ * 2.1 AAAA record type
+ * 
+ *    The AAAA resource record type is a record specific to the Internet
+ *    class that stores a single IPv6 address.
+ * 
+ *    The IANA assigned value of the type is 28 (decimal).
+ * 
+ * 2.2 AAAA data format
+ * 
+ *    A 128 bit IPv6 address is encoded in the data portion of an AAAA
+ *    resource record in network byte order (high-order byte first).
+ * 
+ * 2.3 AAAA query
+ * 
+ *    An AAAA query for a specified domain name in the Internet class
+ *    returns all associated AAAA resource records in the answer section of
+ *    a response.
+ * 
+ *    A type AAAA query does not trigger additional section processing.
+ * 
+ * 2.4 Textual format of AAAA records
+ * 
+ *    The textual representation of the data portion of the AAAA resource
+ *    record used in a master database file is the textual representation
+ *    of an IPv6 address as defined in [3].
+ * 
+ * 2.5 IP6.ARPA Domain
+ * 
+ *    A special domain is defined to look up a record given an IPv6
+ *    address.  The intent of this domain is to provide a way of mapping an
+ *    IPv6 address to a host name, although it may be used for other
+ *    purposes as well.  The domain is rooted at IP6.ARPA.
+ * 
+ *    An IPv6 address is represented as a name in the IP6.ARPA domain by a
+ *    sequence of nibbles separated by dots with the suffix ".IP6.ARPA".
+ *    The sequence of nibbles is encoded in reverse order, i.e., the
+ *    low-order nibble is encoded first, followed by the next low-order
+ *    nibble and so on.  Each nibble is represented by a hexadecimal digit.
+ *    For example, the reverse lookup domain name corresponding to the
+ *    address
+ * 
+ *        4321:0:1:2:3:4:567:89ab
+ * 
+ *    would be
+ * 
+ *    b.a.9.8.7.6.5.0.4.0.0.0.3.0.0.0.2.0.0.0.1.0.0.0.0.0.0.0.1.2.3.4.IP6.

+ * 
+ * VERSION      Version number of the representation.  This must be zero.
+ *              Implementations are required to check this field and make
+ *              no assumptions about the format of unrecognized versions.
+ * 
+ * SIZE         The diameter of a sphere enclosing the described entity, in
+ *              centimeters, expressed as a pair of four-bit unsigned
+ *              integers, each ranging from zero to nine, with the most
+ *              significant four bits representing the base and the second
+ *              number representing the power of ten by which to multiply
+ *              the base.  This allows sizes from 0e0 (<1cm) to 9e9
+ *              (90,000km) to be expressed.  This representation was chosen
+ *              such that the hexadecimal representation can be read by
+ *              eye; 0x15 = 1e5.  Four-bit values greater than 9 are
+ *              undefined, as are values with a base of zero and a non-zero
+ *              exponent.
+ * 
+ *              Since 20000000m (represented by the value 0x29) is greater
+ *              than the equatorial diameter of the WGS 84 ellipsoid
+ *              (12756274m), it is therefore suitable for use as a
+ *              "worldwide" size.
+ * 
+ * HORIZ PRE    The horizontal precision of the data, in centimeters,
+ *              expressed using the same representation as SIZE.  This is
+ *              the diameter of the horizontal "circle of error", rather
+ *              than a "plus or minus" value.  (This was chosen to match
+ *              the interpretation of SIZE; to get a "plus or minus" value,
+ *              divide by 2.)
+ * 
+ * VERT PRE     The vertical precision of the data, in centimeters,
+ *              expressed using the sane representation as for SIZE.  This
+ *              is the total potential vertical error, rather than a "plus
+ *              or minus" value.  (This was chosen to match the
+ *              interpretation of SIZE; to get a "plus or minus" value,
+ *              divide by 2.)  Note that if altitude above or below sea
+ *              level is used as an approximation for altitude relative to
+ *              the [WGS 84] ellipsoid, the precision value should be
+ *              adjusted.
+ * 
+ * LATITUDE     The latitude of the center of the sphere described by the
+ *              SIZE field, expressed as a 32-bit integer, most significant
+ *              octet first (network standard byte order), in thousandths
+ *              of a second of arc.  2^31 represents the equator; numbers
+ *              above that are north latitude.
+ * 
+ * LONGITUDE    The longitude of the center of the sphere described by the
+ *              SIZE field, expressed as a 32-bit integer, most significant
+ *              octet first (network standard byte order), in thousandths
+ *              of a second of arc, rounded away from the prime meridian.
+ *              2^31 represents the prime meridian; numbers above that are
+ *              east longitude.
+ * 
+ * ALTITUDE     The altitude of the center of the sphere described by the
+ *              SIZE field, expressed as a 32-bit integer, most significant
+ *              octet first (network standard byte order), in centimeters,
+ *              from a base of 100,000m below the [WGS 84] reference
+ *              spheroid used by GPS (semimajor axis a=6378137.0,
+ *              reciprocal flattening rf=298.257223563).  Altitude above
+ *              (or below) sea level may be used as an approximation of
+ *              altitude relative to the the [WGS 84] spheroid, though due
+ *              to the Earth's surface not being a perfect spheroid, there
+ *              will be differences.  (For example, the geoid (which sea
+ *              level approximates) for the continental US ranges from 10
+ *              meters to 50 meters below the [WGS 84] spheroid.
+ *              Adjustments to ALTITUDE and/or VERT PRE will be necessary
+ *              in most cases.  The Defense Mapping Agency publishes geoid
+ *              height values relative to the [WGS 84] ellipsoid.

+ *    <character-string> and <domain-name> as used here are defined in RFC
+ *    1035 [7].
+ * 
+ *    ORDER
+ *       A 16-bit unsigned integer specifying the order in which the NAPTR
+ *       records MUST be processed in order to accurately represent the
+ *       ordered list of Rules.  The ordering is from lowest to highest.
+ *       If two records have the same order value then they are considered
+ *       to be the same rule and should be selected based on the
+ *       combination of the Preference values and Services offered.
+ * 
+ *    PREFERENCE
+ *       Although it is called "preference" in deference to DNS
+ *       terminology, this field is equivalent to the Priority value in the
+ *       DDDS Algorithm.  It is a 16-bit unsigned integer that specifies
+ *       the order in which NAPTR records with equal Order values SHOULD be
+ *       processed, low numbers being processed before high numbers.  This
+ *       is similar to the preference field in an MX record, and is used so
+ *       domain administrators can direct clients towards more capable
+ *       hosts or lighter weight protocols.  A client MAY look at records
+ *       with higher preference values if it has a good reason to do so
+ *       such as not supporting some protocol or service very well.
+ * 
+ *       The important difference between Order and Preference is that once
+ *       a match is found the client MUST NOT consider records with a
+ *       different Order but they MAY process records with the same Order
+ *       but different Preferences.  The only exception to this is noted in
+ *       the second important Note in the DDDS algorithm specification
+ *       concerning allowing clients to use more complex Service
+ *       determination between steps 3 and 4 in the algorithm.  Preference
+ *       is used to give communicate a higher quality of service to rules
+ *       that are considered the same from an authority standpoint but not
+ *       from a simple load balancing standpoint.
+ * 
+ *       It is important to note that DNS contains several load balancing
+ *       mechanisms and if load balancing among otherwise equal services
+ *       should be needed then methods such as SRV records or multiple A
+ *       records should be utilized to accomplish load balancing.
+ * 
+ *    FLAGS
+ *       A <character-string> containing flags to control aspects of the
+ *       rewriting and interpretation of the fields in the record.  Flags
+ *       are single characters from the set A-Z and 0-9.  The case of the
+ *       alphabetic characters is not significant.  The field can be empty.
+ * 
+ *       It is up to the Application specifying how it is using this
+ *       Database to define the Flags in this field.  It must define which
+ *       ones are terminal and which ones are not.
+ * 
+ *    SERVICES
+ *       A <character-string> that specifies the Service Parameters
+ *       applicable to this this delegation path.  It is up to the
+ *       Application Specification to specify the values found in this
+ *       field.
+ * 
+ *    REGEXP
+ *       A <character-string> containing a substitution expression that is
+ *       applied to the original string held by the client in order to
+ *       construct the next domain name to lookup.  See the DDDS Algorithm
+ *       specification for the syntax of this field.
+ * 
+ *       As stated in the DDDS algorithm, The regular expressions MUST NOT
+ *       be used in a cumulative fashion, that is, they should only be
+ *       applied to the original string held by the client, never to the
+ *       domain name produced by a previous NAPTR rewrite.  The latter is
+ *       tempting in some applications but experience has shown such use to
+ *       be extremely fault sensitive, very error prone, and extremely
+ *       difficult to debug.
+ * 
+ *    REPLACEMENT
+ *       A <domain-name> which is the next domain-name to query for
+ *       depending on the potential values found in the flags field.  This
+ *       field is used when the regular expression is a simple replacement
+ *       operation.  Any value in this field MUST be a fully qualified
+ *       domain-name.  Name compression is not to be used for this field.
+ * 
+ *       This field and the REGEXP field together make up the Substitution
+ *       Expression in the DDDS Algorithm.  It is simply a historical
+ *       optimization specifically for DNS compression that this field
+ *       exists.  The fields are also mutually exclusive.  If a record is
+ *       returned that has values for both fields then it is considered to
+ *       be in error and SHOULD be either ignored or an error returned.

+ * 5.2 NXT RDATA Format
+ * 
+ *    The RDATA for an NXT RR consists simply of a domain name followed by
+ *    a bit map.
+ * 
+ *    The type number for the NXT RR is 30.
+ * 
+ *                            1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 3 3
+ *        0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
+ *       +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ *       |         next domain name                                      /
+ *       +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ *       |                    type bit map                               /
+ *       +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ * 
+ *    The NXT RR type bit map is one bit per RR type present for the owner
+ *    name similar to the WKS socket bit map.  The first bit represents RR
+ *    type zero (an illegal type which should not be present.) A one bit
+ *    indicates that at least one RR of that type is present for the owner
+ *    name.  A zero indicates that no such RR is present.  All bits not
+ *    specified because they are beyond the end of the bit map are assumed
+ *    to be zero.  Note that bit 30, for NXT, will always be on so the
+ *    minimum bit map length is actually four octets.  The NXT bit map
+ *    should be printed as a list of RR type mnemonics or decimal numbers
+ *    similar to the WKS RR.
+ * 
+ *    The domain name may be compressed with standard DNS name compression
+ *    when being transmitted over the network.  The size of the bit map can
+ *    be inferred from the RDLENGTH and the length of the next domain name.
