=head1 NAME
CTest - Perl extension for testing local 'C' routines
=head1 SYNOPSIS
use CTest;
=head1 DESCRIPTION
This module consists of various test routines to exercise the subroutines in
the the 'C' pieces for F<dnsbls>
=over 4
=item * $rv=t_main(qw(program_name args, arg2,..., argN);
input: program name
-d
-f etc... see readme
output: number of arguments passed
=item * t_setsig();
set the signal handler.
test routine should issue SIGINT
to child and catch resulting text
=item * t_set_parent(val);
set the value of "parent"
return the previous value
=item * t_set_qflag(val);
set the value of "qflag"
return the previous value
=item * t_set_stop(val);
set the value of "stop"
return the previous value
This flag forces 'main' to return(0)
as soon as it enters the -T print
routine BEFORE it issues STDOUT
=item * $pid = t_pidrun()
input: none
output: pid found in pid file
see t_chk4pid below
=item * t_savpid(path2pidfile)
input: path to pid file
output: none
saves the pid of the current process
in the pid file (path2pidfile)
=item * $pidpath = t_chk4pid(path)
input: path to pid file
output: undef or path to pid file
checks for a process running with the pid
found in "path". If the process is running
return undef, otherwise return the "path".
Always places the "pid" found in pid file
into the variable "pidrun".
=item * $pidpath = t_pidpath();
input: none
output: current pidpath/file
=item * $err = t_init(home,...);
input: dbhome
db file name
secondary db file name (optional)
output: 0 or error code
=item * $err = t_dump(which);
input: 0 = primary db
nz = secondary db
output: 0 or error code
prints database to STDOUT in the format
dot.quad.addr => timestamp
=item * t_close();
input: none
output: none
close the database files and environment
=item * $data = t_get(which,addr);
input: 0 = primary db
nz = secondary db
output: data (long)
or undef if not there
=item * $short_hostname = t_short();
input: none
output: short host name
=item * $rv = t_munge(fd,bp,msglen,is_tcp)
input: handle number, [fileno(FD)]
pointer buffer,
length of buffer,
tcp flag
output: number of bytes processed,
-1 on error
NOTES: is_tcp
Setting is_tcp true forces TCP mode in the ns.c
is_tcp tells ns.c how to process the requests
(TCP or UDP) and specifically how to process AXFR
requests so we can test all of the program branches.
is_tcp = 0 use UDP
is_tcp = 1 use TCP, AXFR in one message if possible
is_tcp = 2 use TCP, AXFR in two messages. The first
message contains all overhead records, SOA,
NS, MX and local host stuff. The second
message contains all numeric A & TXT records
or as many as will fit.
is_tcp >= 3 The first record is the same as is_tcp 2.
Each additional record contains an A + TXT
record pair for a particular numeric record,
with the last record containing only the SOA
=item * $rv = t_cmdline(cmd,stuff);
input: one of n a b e m L I z c P Z
parameter
output: true on success else false
SEE: command line parameters for
dnsbls -n -a -b -e -m -L -I -z -c -P -Z
B<L> sets the name of the local host. If the zone name has been
set already then the zoneEQlocal flag is set appropriately. If local host
name is already set when the zone name is set, zoneEQlocal will again be set
appropriately.
B<I> sets the IP address of the local host
=item * $rv = t_set_resp(seria_rec,stdResp,stdRespBeg);
Set various internal address registers
input: ipaddr for serial record
ipaddr for stdResp
ipaddr for stdRespBeg
output: true on success,
else undef
Set the ip address for db access
=item * $rv = t_cmp_serial(s1,s2);
input: zone serial number pair
returns: 0 s1 = s2
-1 s1 < s2
1 s1 > s2
>1 undefined
=item * $rv = t_name_skip(buf);
input: buffer of characters/numbers
returns: integer offset from begining
of buffer past dn names
=item * $rv = t_set_parent(val);
Set parent pid value
input: new value
returns: old value
=item * $rv = t_set_qflag(val);
Set qflag value
input: new value
returns: old value
=item * @rv or $rv = t_ret_resp();
returns: one or more of zonefile
response values aa,ab,ac,ad
as returned by inet_ntoa
=item * t_initlb();
Initialize ip address nibbles, text responses, A responses, origin level
ah..dz txa..txd aa..ad org to zero
=item * $rv = t_set_org(val);
Set org value
input: new value
returns: old value
=item * @rv or $rv = t_ret_a_nibls();
returns: one or more of zonefile
nibble groups
ah.am.al.az
bh.bm.bl.bz
ch.cm.cl.cz
dh.dm.dl.dz
as returned by inet_ntoa
=item * $rv = t_mybuffer(which)
Returns one of mybuffer, txa, txb, txc, txd as selected by which (0,1,2,3,4)
respectively.
=item * t_set_dbhome(path);
Set dbhome to 'path'
input: /some/path
=item * t_tabout(name,type);
Tab justify to 3 tabs, the name and type => 'mybuffer' which can be
retrieved with B<t_mybuffer(0)>
mybuffer = 'name A '
=item * t_add_A_rec(name,ip_response);
Use 'tabout' to the name, 'A' type plus ip_response code (text)
and put it in 'mybuffer' which can be retrieved with B<t_mybuffer(0)>
The text ip_response code is converted by inet_aton internally for testing.
=item * t_ishift();
Perform shift operation:
ip address nibbles
ch->dh cm->dm cl->dl cz->dz
bh->ch bm->cm bl->cl bz->cz
ah->bh am->bm al->bl az->bz
response codes
ac->ad ab->ac aa->ab
txt responses
txc->txd txb->txc txa->txb
=item * t_precrd(F,name,resp,text);
Print A record line and conditionally TXT line depending on the Zflag
input: File handle,
name fragment,
response code (ascii)
text string
=item * t_oflush(F);
Flush the adress nibbles and related codes and text to the output stream 'F'
input: file handle
=item * t_iload(netaddr,resp,text);
Load the address, response, text record into process stack.
input: netaddr => ah, am, al, az
resp => aa
text => txa
=item * t_iprint(F);
Conditionally print process stack based on the zonefile host address
nibbles.
input: file handle
=item * $rv = t_zone_name();
Return the zone name
input: none
returns: zone name or undef
=item * $rv = t_zonefile(fd);
Dump a zonefile named 'zonename.tmp' to the db home directory then rename it
to 'zonename.in'
input: file handle
returns: 0 on success
1 no serial number found
-1 start/end serial mismatch
=item * ($delta,$partsum,$partmax,$charsum) = t_ratelimit(
$run,
$new_tv_sec,
$new_tv_usec,
$then_tv_sec,
$then_tv_usec,
$diskmax,
$charsum,
$partsum
);
input: run, true=normal, false=debug/test
struct timeval 'new' sec, usec
struct timeval 'then' sec, usec
diskmax, rate limit chars/sec
charsum, characters so far
partsum, partial sum
returns: timeval delta,
partsum, new average
partmax initial value
charsum total so far or cleared
If either element of 'then' is undefined then the
remaining internal value is used rather than
being set from the input data
