2556 | =head1 METHODS | |
2557 | ||
2558 | =cut | |
2559 | ||
2560 | =head2 new | |
2561 | ||
2562 | Creates a new log object, optionally you can specify a filename here to | |
5348b6e7 | 2563 | indicate the file to log to. If no log file is specified, you can specify one |
3fda8c4c ML |
2564 | later with method setfile, or indicate you no longer want logging with method |
2565 | nofile. | |
2566 | ||
2567 | Until one of these methods is called, all log calls will buffer messages ready | |
2568 | to write out. | |
2569 | ||
2570 | =cut | |
2571 | sub new | |
2572 | { | |
2573 | my $class = shift; | |
2574 | my $filename = shift; | |
2575 | ||
2576 | my $self = {}; | |
2577 | ||
2578 | bless $self, $class; | |
2579 | ||
2580 | if ( defined ( $filename ) ) | |
2581 | { | |
2582 | open $self->{fh}, ">>", $filename or die("Couldn't open '$filename' for writing : $!"); | |
2583 | } | |
2584 | ||
2585 | return $self; | |
2586 | } | |
2587 | ||
2588 | =head2 setfile | |
2589 | ||
2590 | This methods takes a filename, and attempts to open that file as the log file. | |
2591 | If successful, all buffered data is written out to the file, and any further | |
2592 | logging is written directly to the file. | |
2593 | ||
2594 | =cut | |
2595 | sub setfile | |
2596 | { | |
2597 | my $self = shift; | |
2598 | my $filename = shift; | |
2599 | ||
2600 | if ( defined ( $filename ) ) | |
2601 | { | |
2602 | open $self->{fh}, ">>", $filename or die("Couldn't open '$filename' for writing : $!"); | |
2603 | } | |
2604 | ||
2605 | return unless ( defined ( $self->{buffer} ) and ref $self->{buffer} eq "ARRAY" ); | |
2606 | ||
2607 | while ( my $line = shift @{$self->{buffer}} ) | |
2608 | { | |
2609 | print {$self->{fh}} $line; | |
2610 | } | |
2611 | } | |
2612 | ||
2613 | =head2 nofile | |
2614 | ||
2615 | This method indicates no logging is going to be used. It flushes any entries in | |
2616 | the internal buffer, and sets a flag to ensure no further data is put there. | |
2617 | ||
2618 | =cut | |
2619 | sub nofile | |
2620 | { | |
2621 | my $self = shift; | |
2622 | ||
2623 | $self->{nolog} = 1; | |
2624 | ||
2625 | return unless ( defined ( $self->{buffer} ) and ref $self->{buffer} eq "ARRAY" ); | |
2626 | ||
2627 | $self->{buffer} = []; | |
2628 | } | |
2629 | ||
2630 | =head2 _logopen | |
2631 | ||
2632 | Internal method. Returns true if the log file is open, false otherwise. | |
2633 | ||
2634 | =cut | |
2635 | sub _logopen | |
2636 | { | |
2637 | my $self = shift; | |
2638 | ||

2640 | return 0; | |
2641 | } | |
2642 | ||
2643 | =head2 debug info warn fatal | |
2644 | ||
2645 | These four methods are wrappers to _log. They provide the actual interface for | |
2646 | logging data. | |
2647 | ||
2648 | =cut | |
2649 | sub debug { my $self = shift; $self->_log("debug", @_); } | |
2650 | sub info { my $self = shift; $self->_log("info" , @_); } | |
2651 | sub warn { my $self = shift; $self->_log("warn" , @_); } | |
2652 | sub fatal { my $self = shift; $self->_log("fatal", @_); } | |
2653 | ||
2654 | =head2 _log | |
2655 | ||
2656 | This is an internal method called by the logging functions. It generates a | |
2657 | timestamp and pushes the logged line either to file, or internal buffer. | |
2658 | ||
2659 | =cut | |
2660 | sub _log | |
2661 | { | |
2662 | my $self = shift; | |
2663 | my $level = shift; | |
2664 | ||
2665 | return if ( $self->{nolog} ); | |
2666 | ||
2667 | my @time = localtime; | |
2668 | my $timestring = sprintf("%4d-%02d-%02d %02d:%02d:%02d : %-5s", | |
2669 | $time[5] + 1900, | |
2670 | $time[4] + 1, | |
2671 | $time[3], | |
2672 | $time[2], | |
2673 | $time[1], | |
2674 | $time[0], | |
2675 | uc $level, | |
2676 | ); | |
2677 | ||
2678 | if ( $self->_logopen ) | |
2679 | { | |
2680 | print {$self->{fh}} $timestring . " - " . join(" ",@_) . "\n"; | |
2681 | } else { | |
2682 | push @{$self->{buffer}}, $timestring . " - " . join(" ",@_) . "\n"; | |
2683 | } | |
2684 | } | |
2685 | ||
2686 | =head2 DESTROY | |
2687 | ||
2688 | This method simply closes the file handle if one is open | |
2689 | ||
2690 | =cut | |
2691 | sub DESTROY | |
2692 | { | |
