.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Syslog messages\*(--as standardized in RFC3164\-\-embed a priority number (the \s-1PRI\s0
part) which is composed of a severity and a facility value. The constants which
encode these values are specified in section 4.1.1, and are made available by
this module. For instance, the exportable \s-1LOG_FTP\s0 constant has a value of 11,
the value for the \s-1FTP\s0 facility.
.SH "EXPORTS"

Nothing is exported by default. You may optionally import individual constants
and functions or groups of them:

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module will parse a Zone File and put all the Resource Records (RRs)
into an anonymous hash structure. Various record types are supported, see the
methods section for details. It could be useful for maintaining \s-1DNS\s0 zones,
or for transferring \s-1DNS\s0 zones to other servers. If you want to generate an
XML-friendly version of your zone files, it is easy to use XML::Simple with
this module once you have parsed the zone file.
.PP
DNS::ZoneParse scans the \s-1DNS\s0 zone file \- removes comments and seperates
the file into its constituent records. It then parses each record and
stores the records internally. See below for information on the accessor
methods.
.SS "\s-1METHODS\s0"
.IX Subsection "METHODS"
.IP "new" 4
.IX Item "new"
This creates the DNS::ZoneParse object and loads the zone file.
.Sp
Example:
my \f(CW$zonefile\fR = DNS::ZoneParse\->new(\*(L"/path/to/zonefile.db\*(R");
.Sp
You can also initialise the object with the contents of a file:
my \f(CW$zonefile\fR = DNS::ZoneParse\->new( \e$zone_contents );
.Sp
You can pass a second, optional parameter to the constructor to supply an
\&\f(CW$origin\fR if none can be found in the zone file.
.Sp
.Vb 1
\& my $zonefile = DNS::ZoneParse\->new( \e$zone_contents, $origin );
.Ve
.Sp
You can pass a third, optional parameter to the constructor to supply a
callback which will be called whenever an unparsable line is encountered in
the zone file. See \f(CW\*(C`on_unparseable_line\*(C'\fR for details on this parameter and
how errors are handled when parsing zone files.
.Sp
If you plan to pass a on_unparseable_line callback but do not wish to specify
an \f(CW$origin\fR, pass 'undef' as the \f(CW$origin\fR parameter.
.IP "a(), \fIcname()\fR, \fIsrv()\fR, \fImx()\fR, \fIns()\fR, \fIptr()\fR, \fItxt()\fR, \fIhinfo()\fR, \fIrp()\fR, \fIloc()\fR" 4
.IX Item "a(), cname(), srv(), mx(), ns(), ptr(), txt(), hinfo(), rp(), loc()"
These methods return references to the resource records. For example:
.Sp
.Vb 1
\& my $mx = $zonefile\->mx;
.Ve
.Sp
Returns the mx records in an array reference.
.Sp
All records (except \s-1SOA\s0) have the following properties: 'ttl', 'class',
\&'host', 'name', '\s-1ORIGIN\s0'.
.Sp
\&\s-1MX\s0 records also have a 'priority' property.
.Sp
\&\s-1SRV\s0 records also have 'priority', 'weight' and 'port' properties.
.Sp
\&\s-1TXT\s0 records also have a 'text' property representing the record's 'txt\-data'
descriptive text.
.Sp
\&\s-1HINFO\s0 records also have 'cpu' and 'os' properties.
.Sp
\&\s-1RP\s0 records also have 'mbox' and 'text' properties.
.Sp
\&\s-1LOC\s0 records also have 'd1', 'm1', 's1', 'NorS', 'd2', 'm2', 's2', 'EorW',
\&'alt', 'siz', 'hp', and 'vp', as per \s-1RFC\s0 1876.
.Sp
If there are no records of a given type in the zone, the call will croak with
an error message about an invalid method. (This is not an ideal behavior, but
has been kept for backwards compatibility.)
.Sp
The '\s-1ORIGIN\s0' property is the fully-qualified origin of the record. See
fqname for details on constructing a fully qualified domain name. Note: for
\&\s-1SOA\s0 records, the '\s-1ORIGIN\s0' will match the 'origin' property when the \s-1SOA\s0 record
is specified as fully qualified.
.IP "\fIsoa()\fR" 4
.IX Item "soa()"
Returns a hash reference with the following properties:
\&'serial', 'origin', 'primary', 'refresh', 'retry', 'ttl', 'minimumTTL',
\&'email', 'expire', 'class', '\s-1ORIGIN\s0'.
.Sp
The '\s-1ORIGIN\s0' property is returned separate from 'origin' property, though the
data may be the same. '\s-1ORIGIN\s0' represents the implicit origin for the record
while 'origin' represents the origin specified on the \s-1SOA\s0 line in the file.
.Sp
If the 'origin' value is relative (that is, does not end with a '.'), the
actual zone for which the \s-1SOA\s0 line applies must be computed by concatenating
the 'origin' and '\s-1ORIGIN\s0' values. See fqname for details. If the 'origin'
value is absolute, no computation is necessary and 'origin' is the same as
\&'\s-1ORIGIN\s0'.
.IP "\fIgenerate()\fR" 4
.IX Item "generate()"
Returns an array of hashes representing \f(CW$GENERATE\fR directives present in the
zone. Note, \f(CW$GENERATE\fR directives are BIND-specific additions. They are not
expanded by DNS::ZoneParse, but users are able to access and modify these
directives. The following properties are returned:
.Sp
\&'range', 'lhs', 'ttl', 'class', 'type', 'rhs', '\s-1ORIGIN\s0'.
.Sp
See the \s-1BIND\s0 documentation for details on the syntax and usage of the \f(CW$GENERATE\fR
directive.
.IP "dump" 4
.IX Item "dump"
Returns a copy of the datastructute that stores all the resource records. This
might be useful if you want to quickly transform the data into another format,
such as \s-1XML\s0.
.IP "fqname" 4
.IX Item "fqname"
Takes a single parameter, a hash reference containing a record.
.Sp
Returns the fully qualified name of this record, with a trailing '.'. In most
cases this is as simple as concatenating the 'name' and '\s-1ORIGIN\s0' with a '.'
unless 'name' is '@', in which case the fqname is simply the '\s-1ORIGIN\s0'. For
\&\s-1SOA\s0 records, the same process is performed on the 'origin' instead of 'name'.
.Sp
Please note, fqname will not expand the right hand side of a record (ie,
\&\s-1CNAME\s0, \s-1SOA\s0, \s-1MX\s0, etc). The user must expand these values via the above method.
.IP "ttl_to_int" 4
.IX Item "ttl_to_int"
Takes a single parameter, a string representing a valid record \s-1TTL\s0.
.Sp
Returns an integer representing the number of seconds the \s-1TTL\s0 represents.
Note, this does not take into account any leap-years, leap-seconds, \s-1DST\s0
changes, etc. It is simply the count of the number of seconds in the specified
period of time.
.IP "new_serial" 4
.IX Item "new_serial"
\&\f(CW\*(C`new_serial()\*(C'\fR incriments the Zone serial number. It will generate a
date-based serial number. Or you can pass a positive number to add to the
current serial number.
.Sp
Examples:
.Sp
.Vb 4
\& $zonefile\->new_serial();
\& # generates a new serial number based on date:
\& # YYYYmmddHH format, incriments current serial
\& # by 1 if the new serial is still smaller
\&
\& $zonefile\->new_serial(50);
\& # adds 50 to the original serial number
.Ve
.IP "output" 4
.IX Item "output"
\&\f(CW\*(C`output()\*(C'\fR returns the new zone file output as a string. If you wish your
output formatted differently, you can pass the output of \f(CW\*(C`dump()\*(C'\fR to your
favourite templating module.
.IP "last_parse_error_count" 4
.IX Item "last_parse_error_count"
Returns a count of the number of unparsable lines from the last time a
zone file was parsed. If no zone file has been parsed yet, returns 0.
.Sp
If you want to be sure that a zone file was parsed completely and without
error, the return value of this method should be checked after the constructor
is called (or after a call to _parse).
.IP "on_unparseable_line" 4
.IX Item "on_unparseable_line"
\&\f(CW\*(C`on_unparseable_line()\*(C'\fR is an accessor method for the callback used when an
unparseable line is encountered while parsing a zone file. If not set,
DNS::ZoneParse will \f(CW\*(C`croak\*(C'\fR when an unparsable line is encountered, but will
continue to parse the file. Each time an unparsable line is encountered, an
internal counter is incrememnted. See \f(CW\*(C`last_parse_error_count\*(C'\fR for details.
.Sp
The callback is passed four parameters, a reference to the DNS::ZoneParse
object which is doing the parsing, the text of the line that is unable to be
parsed, the text of the reason the line could not be parsed, and the text of
the last successfully parsed line.
.Sp
If you want to abort parsing when an unparsable line is found, call \f(CW\*(C`die\*(C'\fR
from within your callback and catch that die with an eval block around the
DNS::ZoneParse constructor (or call to _parse).
.Sp
The method takes a single optional parameter, a code reference to the function
that will be called when an unparsable line is reached. Returns a reference to
the last callback. If passed an undefined value, a reference to the current
callback is returned. If passed any other value, undef is returned.

.IX Header "API"
The DNS::ZoneParse \s-1API\s0 may change in future versions. At present, the parsing
is not as strict as it should be and support for \f(CW$ORIGIN\fR and \f(CW$TTL\fR is
quite basic. It would also be nice to support the \f(CW\*(C`INCLUDE\*(C'\fR
statement. Furthermore, parsing large zone files with thousands of records can
use lots of memory \- some people have requested a callback interface.

.SH "NAME"
Log::Syslog::Fast \- Perl extension for sending syslog messages over TCP, UDP,
or UNIX sockets with minimal CPU overhead.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 3
\& use Log::Syslog::Fast \*(Aq:all\*(Aq;
\& my $logger = Log::Syslog::Fast\->new(LOG_UDP, "127.0.0.1", 514, LOG_LOCAL0, LOG_INFO, "mymachine", "logger");
\& $logger\->send("log message", time);
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module sends syslog messages over a network socket. It works like
Sys::Syslog in setlogsock's 'udp', 'tcp', or 'unix' modes, but without the
significant \s-1CPU\s0 overhead of that module when used for high-volume logging. Use
of this specialized module is only recommended if 1) you must use network
syslog as a messaging transport but 2) need to minimize the time spent in the
logger.
.PP
This module supercedes the less general Log::Syslog::UDP.
.SH "METHODS"
.IX Header "METHODS"
.ie n .IP "Log::Syslog::Fast\->new($proto, $hostname, $port, $facility, $severity, $sender, $name);" 4
.el .IP "Log::Syslog::Fast\->new($proto, \f(CW$hostname\fR, \f(CW$port\fR, \f(CW$facility\fR, \f(CW$severity\fR, \f(CW$sender\fR, \f(CW$name\fR);" 4
.IX Item "Log::Syslog::Fast->new($proto, $hostname, $port, $facility, $severity, $sender, $name);"
Create a new Log::Syslog::Fast object with the following parameters:
.RS 4
.ie n .IP "$proto" 4
.el .IP "\f(CW$proto\fR" 4
.IX Item "$proto"
The transport protocol: one of \s-1LOG_TCP\s0, \s-1LOG_UDP\s0, or \s-1LOG_UNIX\s0.
.Sp
If \s-1LOG_TCP\s0 or \s-1LOG_UNIX\s0 is used, calls to \f(CW$logger\fR\->\fIsend()\fR will block until
remote receipt of the message is confirmed. If \s-1LOG_UDP\s0 is used, the call will
never block and may fail if insufficient buffer space exists in the network
stack (in which case an exception will be thrown).
.Sp
With \s-1LOG_UNIX\s0, \fI\->new\fR will first attempt to connect with a \s-1SOCK_STREAM\s0
socket, and then try a \s-1SOCK_DGRAM\s0 if that is what the server expects (e.g.
rsyslog).
.ie n .IP "$hostname" 4
.el .IP "\f(CW$hostname\fR" 4
.IX Item "$hostname"
For \s-1LOG_TCP\s0 and \s-1LOG_UDP\s0, the destination hostname where a syslogd is running.
For \s-1LOG_UNIX\s0, the path to the \s-1UNIX\s0 socket where syslogd is listening (typically
/dev/log).
.ie n .IP "$port" 4
.el .IP "\f(CW$port\fR" 4
.IX Item "$port"
For \s-1LOG_TCP\s0 and \s-1LOG_UDP\s0, the destination port where a syslogd is listening,
usually 514. Ignored for \s-1LOG_UNIX\s0.
.ie n .IP "$facility" 4
.el .IP "\f(CW$facility\fR" 4
.IX Item "$facility"
The syslog facility constant, eg 16 for 'local0'. See \s-1RFC3164\s0 section 4.1.1 (or
) for appropriate constant values. See \s-1EXPORTS\s0 below
for making these available by name.
.Sp
The \fIpriority\fR value is computed from the facility and severity per the \s-1RFC\s0.
.ie n .IP "$severity" 4
.el .IP "\f(CW$severity\fR" 4
.IX Item "$severity"
The syslog severity constant, eg 6 for 'info'. See \s-1RFC3164\s0 section 4.1.1 (or
) for appropriate constant values. See \s-1EXPORTS\s0 below
for making these available by name.
.ie n .IP "$sender" 4
.el .IP "\f(CW$sender\fR" 4
.IX Item "$sender"
The originating hostname. Sys::Hostname::hostname is typically a reasonable
source for this.

.IX Item "$name"
The program name or tag to use for the message.

.el .IP "\f(CW$logger\fR\->emit($logmsg, [$time])" 4
.IX Item "$logger->emit($logmsg, [$time])"
.PD
Send a syslog message through the configured logger. If \f(CW$time\fR is not provided,
\&\fB\f(BItime\fB\|(2)\fR will be called for you. That doubles the syscalls per message, so
try to pass it if you're already calling \fItime()\fR yourself.
.Sp
\&\->send may throw an exception if the system call fails (e.g. the transport
becomes disconnected for connected protocols, or the kernel buffer is full for
unconnected). For this reason it is usually wise to wrap calls with an
exception handler. Likewise, calling \->send from a \f(CW$SIG\fR{_\|_DIE_\|_} handler is
unwise.
.Sp
\&\fBemit\fR is an alias for \fBsend\fR.
.Sp
\&\fB\s-1NEWLINE\s0 \s-1CAVEAT\s0\fR
.Sp
Note that \fBsend\fR does not add any newline character(s) to its input. You will
certainly want to do this yourself for \s-1TCP\s0 connections, or the server will not
treat each message as a separate line. However with \s-1UDP\s0 the server should
accept a message without a trailing newline (though some implementations may
have difficulty with that).
.ie n .IP "$logger\->set_receiver($proto, $hostname, $port)" 4
.el .IP "\f(CW$logger\fR\->set_receiver($proto, \f(CW$hostname\fR, \f(CW$port\fR)" 4
.IX Item "$logger->set_receiver($proto, $hostname, $port)"
Change the protocol, destination host, and port. This will force a reconnection
in \s-1LOG_TCP\s0 or \s-1LOG_UNIX\s0 mode.
.ie n .IP "$logger\->set_priority($facility, $severity)" 4
.el .IP "\f(CW$logger\fR\->set_priority($facility, \f(CW$severity\fR)" 4

.ie n .IP "$logger\->set_format($format)" 4
.el .IP "\f(CW$logger\fR\->set_format($format)" 4
.IX Item "$logger->set_format($format)"
Change the message format. This should be either the constant \s-1LOG_RFC3164\s0 (the
default) or \s-1LOG_RFC5424\s0.
.ie n .IP "$logger\->\fIget_priority()\fR" 4

Returns the current message format.
.SH "UNREACHABLE SERVERS"
.IX Header "UNREACHABLE SERVERS"
If the remote syslogd is unreachable, certain methods may throw an exception or
raise a signal:
.IP "\(bu" 4
\&\s-1LOG_TCP\s0
.Sp
If the server is unreachable at connect time, \fI\->new\fR will fail with an
exception. If an established connection is closed remotely, \fI\->send\fR will
fail with an exception.
.IP "\(bu" 4
\&\s-1LOG_UDP\s0
.Sp
As \s-1UDP\s0 is connectionless, \fI\->new\fR will not throw an error as no attempt to
connect is made then. However, if the remote server starts or becomes unreachable and
1) the host is alive but 2) not listening on the specified port, and
3) \s-1ICMP\s0 packets are routable to the client, an exception \fBmay\fR be thrown by \fI\->send\fR; note that this may happen only on the second call, and subsequently
every other one. This behavior also depends on specific kernel interactions.
.IP "\(bu" 4
\&\s-1LOG_UNIX\s0
.Sp
With both \s-1SOCK_STREAM\-\s0 and SOCK_DGRAM\-based servers, \fI\->new\fR will throw an
exception if the socket is missing or not connectable.
.Sp
With \s-1SOCK_DGRAM\s0, \fI\->send\fR to a peer that went away will throw. With

=head1 NAME
Log::Syslog::Constants - Perl extension containing syslog priority constants as
defined in RFC3164.
=head1 SYNOPSIS
use Log::Syslog::Constants ':all';
@severities = (
LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR, LOG_WARNING, LOG_NOTICE, LOG_INFO,
LOG_DEBUG
);
@facilities = (
LOG_KERN, LOG_USER, LOG_MAIL, LOG_DAEMON, LOG_AUTH, LOG_SYSLOG, LOG_LPR,
LOG_NEWS, LOG_UUCP, LOG_CRON, LOG_AUTHPRIV, LOG_FTP, LOG_LOCAL0,
LOG_LOCAL1, LOG_LOCAL2, LOG_LOCAL3, LOG_LOCAL4, LOG_LOCAL5, LOG_LOCAL6,
LOG_LOCAL7
);
$info_constant = get_severity('INFO');
$local0_constant = get_facility('local0');
=head1 DESCRIPTION
Syslog messages--as standardized in RFC3164--embed a priority number (the PRI
part) which is composed of a severity and a facility value. The constants which
encode these values are specified in section 4.1.1, and are made available by
this module. For instance, the exportable LOG_FTP constant has a value of 11,
the value for the FTP facility.
=head1 EXPORTS
Nothing is exported by default. You may optionally import individual constants
and functions or groups of them:
use Log::Syslog::Constants qw(:severities); # LOG_CRIT, LOG_DEBUG, etc
use Log::Syslog::Constants qw(:facilities); # LOG_CRON, LOG_LOCAL3, etc
use Log::Syslog::Constants qw(:functions); # get_facility, get_severity
use Log::Syslog::Constants qw(:all); # all of the above
=head1 FUNCTIONS
=over 4
=item * get_facility($facility_string)
=item * get_severity($severity_string)
These functions look up a constant value by name, e.g.
C.

=head1 DESCRIPTION
This module will parse a Zone File and put all the Resource Records (RRs)
into an anonymous hash structure. Various record types are supported, see the
L section for details. It could be useful for maintaining DNS zones,
or for transferring DNS zones to other servers. If you want to generate an
XML-friendly version of your zone files, it is easy to use XML::Simple with
this module once you have parsed the zone file.
DNS::ZoneParse scans the DNS zone file - removes comments and seperates
the file into its constituent records. It then parses each record and
stores the records internally. See below for information on the accessor
methods.
=head2 METHODS
=over 4
=item new
This creates the DNS::ZoneParse object and loads the zone file.
Example:
my $zonefile = DNS::ZoneParse->new("/path/to/zonefile.db");
You can also initialise the object with the contents of a file:
my $zonefile = DNS::ZoneParse->new( \$zone_contents );
You can pass a second, optional parameter to the constructor to supply an
C<$origin> if none can be found in the zone file.
my $zonefile = DNS::ZoneParse->new( \$zone_contents, $origin );
You can pass a third, optional parameter to the constructor to supply a
callback which will be called whenever an unparsable line is encountered in
the zone file. See C for details on this parameter and
how errors are handled when parsing zone files.
If you plan to pass a on_unparseable_line callback but do not wish to specify
an C<$origin>, pass 'undef' as the C<$origin> parameter.
=item a(), cname(), srv(), mx(), ns(), ptr(), txt(), hinfo(), rp(), loc()
These methods return references to the resource records. For example:
my $mx = $zonefile->mx;
Returns the mx records in an array reference.
All records (except SOA) have the following properties: 'ttl', 'class',
'host', 'name', 'ORIGIN'.
MX records also have a 'priority' property.
SRV records also have 'priority', 'weight' and 'port' properties.
TXT records also have a 'text' property representing the record's 'txt-data'
descriptive text.
HINFO records also have 'cpu' and 'os' properties.
RP records also have 'mbox' and 'text' properties.
LOC records also have 'd1', 'm1', 's1', 'NorS', 'd2', 'm2', 's2', 'EorW',
'alt', 'siz', 'hp', and 'vp', as per RFC 1876.
If there are no records of a given type in the zone, the call will croak with
an error message about an invalid method. (This is not an ideal behavior, but
has been kept for backwards compatibility.)
The 'ORIGIN' property is the fully-qualified origin of the record. See
L for details on constructing a fully qualified domain name. Note: for
SOA records, the 'ORIGIN' will match the 'origin' property when the SOA record
is specified as fully qualified.
=item soa()
Returns a hash reference with the following properties:
'serial', 'origin', 'primary', 'refresh', 'retry', 'ttl', 'minimumTTL',
'email', 'expire', 'class', 'ORIGIN'.
The 'ORIGIN' property is returned separate from 'origin' property, though the
data may be the same. 'ORIGIN' represents the implicit origin for the record
while 'origin' represents the origin specified on the SOA line in the file.
If the 'origin' value is relative (that is, does not end with a '.'), the
actual zone for which the SOA line applies must be computed by concatenating
the 'origin' and 'ORIGIN' values. See L for details. If the 'origin'
value is absolute, no computation is necessary and 'origin' is the same as
'ORIGIN'.
=item generate()
Returns an array of hashes representing $GENERATE directives present in the
zone. Note, $GENERATE directives are BIND-specific additions. They are not
expanded by DNS::ZoneParse, but users are able to access and modify these
directives. The following properties are returned:
'range', 'lhs', 'ttl', 'class', 'type', 'rhs', 'ORIGIN'.
See the BIND documentation for details on the syntax and usage of the $GENERATE
directive.
=item dump
Returns a copy of the datastructute that stores all the resource records. This
might be useful if you want to quickly transform the data into another format,
such as XML.
=item fqname
Takes a single parameter, a hash reference containing a record.
Returns the fully qualified name of this record, with a trailing '.'. In most
cases this is as simple as concatenating the 'name' and 'ORIGIN' with a '.'
unless 'name' is '@', in which case the fqname is simply the 'ORIGIN'. For
SOA records, the same process is performed on the 'origin' instead of 'name'.
Please note, fqname will not expand the right hand side of a record (ie,
CNAME, SOA, MX, etc). The user must expand these values via the above method.
=item ttl_to_int
Takes a single parameter, a string representing a valid record TTL.
Returns an integer representing the number of seconds the TTL represents.
Note, this does not take into account any leap-years, leap-seconds, DST
changes, etc. It is simply the count of the number of seconds in the specified
period of time.
=item new_serial
C incriments the Zone serial number. It will generate a
date-based serial number. Or you can pass a positive number to add to the
current serial number.
Examples:
$zonefile->new_serial();
# generates a new serial number based on date:
# YYYYmmddHH format, incriments current serial
# by 1 if the new serial is still smaller
$zonefile->new_serial(50);
# adds 50 to the original serial number
=item output
C returns the new zone file output as a string. If you wish your
output formatted differently, you can pass the output of C to your
favourite templating module.
=item last_parse_error_count
Returns a count of the number of unparsable lines from the last time a
zone file was parsed. If no zone file has been parsed yet, returns 0.
If you want to be sure that a zone file was parsed completely and without
error, the return value of this method should be checked after the constructor
is called (or after a call to _parse).
=item on_unparseable_line
C is an accessor method for the callback used when an
unparseable line is encountered while parsing a zone file. If not set,
DNS::ZoneParse will C when an unparsable line is encountered, but will
continue to parse the file. Each time an unparsable line is encountered, an
internal counter is incrememnted. See C for details.
The callback is passed four parameters, a reference to the DNS::ZoneParse
object which is doing the parsing, the text of the line that is unable to be
parsed, the text of the reason the line could not be parsed, and the text of
the last successfully parsed line.
If you want to abort parsing when an unparsable line is found, call C
from within your callback and catch that die with an eval block around the
DNS::ZoneParse constructor (or call to _parse).
The method takes a single optional parameter, a code reference to the function
that will be called when an unparsable line is reached. Returns a reference to
the last callback. If passed an undefined value, a reference to the current
callback is returned. If passed any other value, undef is returned.
=back
=head2 EXAMPLES
This script will print the A records in a zone file, add a new A record for the
name "new" and then return the zone file.
use strict;
use DNS::ZoneParse;
my $zonefile = DNS::ZoneParse->new("/path/to/zonefile.db");
print "Current A Records\n";
my $a_records = $zonefile->a();
foreach my $record (@$a_records) {
print "$record->{name} resolves at $record->{host}\n";
}
push (@$a_records, { name => 'new', class => 'IN',
host => '127.0.0.1', ttl => '' });
$zonefile->new_serial();
my $newfile = $zonefile->output();
This script will convert a DNS Zone file to an XML file using XML::Simple.
use strict;
use DNS::ZoneParse;
use XML::Simple;
my $zonefile = DNS::ZoneParse->new("/path/to/zonefile.db");
my $new_xml = XMLout($zonefile->dump,
noattr => 1,
suppressempty => 1,
rootname => $zonefile->origin);
=head1 CHANGES
See F
=head1 API
The DNS::ZoneParse API may change in future versions. At present, the parsing
is not as strict as it should be and support for C<$ORIGIN> and C<$TTL> is
quite basic. It would also be nice to support the C
statement. Furthermore, parsing large zone files with thousands of records can
use lots of memory - some people have requested a callback interface.
=head1 BUGS
I can squash more bugs with your help. Please let me know if you spot something
that doesn't work as expected.
You can report bugs via the CPAN RT:
L
If possible, please provide a diff against F and
F that demonstrates the bug(s).
