Re: [Bigsister-general] Graphs on W2K

[Geir Skomsøy <suppressed>]

Check this bug report/fix:
http://sourceforge.net/tracker/index.php?func=detail&aid=1020336&group_id=14120&atid=114120
I have not tested this fix myself, saw after I made my own fix.

Here is the code that works for me on Win2003, just replace from $| = 1; 
to just before sub unavailable
(I had to give the IUSR  full controll to the /bigsis/tmp directory)

$| = 1;
    print "Pragma: no-cache\n";
    print "Cache-control: no-cache\n";
    print "Content-Type: image/$format\n";
    print "X-rrrdtool:";

    my $tmp;
    if( $Platform::has_fork ) {
    open( _GRAPH, "-|" );
    $rrd->rrd_graph( "-", @args );
    }
    else {
    $tmp = "/bigsis/tmp/graph.$$";
   
    $rrd->rrd_graph( Platform::filepath( $tmp ), @args );
    open( _GRAPH, "<$tmp" );
    }
    # binmode will fail if using FCGI;
    eval {
    binmode STDOUT;
    };
    binmode _GRAPH;
    while( <_GRAPH> ) { print; }
    close _GRAPH;
    unlink $tmp if( $tmp );
}
