1610 | =head1 NAME | |
1611 | ||
1612 | GITCVS::log | |
1613 | ||
1614 | =head1 DESCRIPTION | |
1615 | ||
1616 | This module provides very crude logging with a similar interface to | |
1617 | Log::Log4perl | |
1618 | ||
1619 | =head1 METHODS | |
1620 | ||
1621 | =cut | |
1622 | ||
1623 | =head2 new | |
1624 | ||
1625 | Creates a new log object, optionally you can specify a filename here to | |
1626 | indicate the file to log to. If no log file is specified, you can specifiy one | |
1627 | later with method setfile, or indicate you no longer want logging with method | |
1628 | nofile. | |
1629 | ||
1630 | Until one of these methods is called, all log calls will buffer messages ready | |
1631 | to write out. | |
1632 | ||
1633 | =cut | |
1634 | sub new | |
1635 | { | |
1636 | my $class = shift; | |
1637 | my $filename = shift; | |
1638 | ||
1639 | my $self = {}; | |
1640 | ||
1641 | bless $self, $class; | |
1642 | ||
1643 | if ( defined ( $filename ) ) | |
1644 | { | |
1645 | open $self->{fh}, ">>", $filename or die("Couldn't open '$filename' for writing : $!"); | |
1646 | } | |
1647 | ||
1648 | return $self; | |
1649 | } | |
1650 | ||
1651 | =head2 setfile | |
1652 | ||
1653 | This methods takes a filename, and attempts to open that file as the log file. | |
1654 | If successful, all buffered data is written out to the file, and any further | |
1655 | logging is written directly to the file. | |
1656 | ||
1657 | =cut | |
1658 | sub setfile | |
1659 | { | |
1660 | my $self = shift; | |
1661 | my $filename = shift; | |
1662 | ||
1663 | if ( defined ( $filename ) ) | |
1664 | { | |
1665 | open $self->{fh}, ">>", $filename or die("Couldn't open '$filename' for writing : $!"); | |
1666 | } | |
1667 | ||
1668 | return unless ( defined ( $self->{buffer} ) and ref $self->{buffer} eq "ARRAY" ); | |
1669 | ||
1670 | while ( my $line = shift @{$self->{buffer}} ) | |
1671 | { | |
1672 | print {$self->{fh}} $line; | |
1673 | } | |
1674 | } | |
1675 | ||
1676 | =head2 nofile | |
1677 | ||
1678 | This method indicates no logging is going to be used. It flushes any entries in | |
1679 | the internal buffer, and sets a flag to ensure no further data is put there. | |
1680 | ||
1681 | =cut | |
1682 | sub nofile | |
1683 | { | |
1684 | my $self = shift; | |
1685 | ||
1686 | $self->{nolog} = 1; | |
1687 | ||
1688 | return unless ( defined ( $self->{buffer} ) and ref $self->{buffer} eq "ARRAY" ); | |
1689 | ||
1690 | $self->{buffer} = []; | |
1691 | } | |
1692 | ||
1693 | =head2 _logopen | |
1694 | ||
1695 | Internal method. Returns true if the log file is open, false otherwise. | |
1696 | ||
1697 | =cut | |
1698 | sub _logopen | |
1699 | { | |
1700 | my $self = shift; | |
1701 | ||
1702 | return 1 if ( defined ( $self->{fh} ) and ref $self->{fh} eq "GLOB" ); | |
1703 | return 0; | |
1704 | } | |
1705 | ||
1706 | =head2 debug info warn fatal | |
1707 | ||
1708 | These four methods are wrappers to _log. They provide the actual interface for | |
1709 | logging data. | |
1710 | ||
1711 | =cut | |
1712 | sub debug { my $self = shift; $self->_log("debug", @_); } | |
1713 | sub info { my $self = shift; $self->_log("info" , @_); } | |
1714 | sub warn { my $self = shift; $self->_log("warn" , @_); } | |
1715 | sub fatal { my $self = shift; $self->_log("fatal", @_); } | |
1716 | ||
1717 | =head2 _log | |
1718 | ||
1719 | This is an internal method called by the logging functions. It generates a | |
1720 | timestamp and pushes the logged line either to file, or internal buffer. | |
1721 | ||
1722 | =cut | |
1723 | sub _log | |
1724 | { | |
1725 | my $self = shift; | |
1726 | my $level = shift; | |
1727 | ||
1728 | return if ( $self->{nolog} ); | |
1729 | ||

1732 | $time[5] + 1900, | |
1733 | $time[4] + 1, | |
1734 | $time[3], | |
1735 | $time[2], | |
1736 | $time[1], | |
1737 | $time[0], | |
1738 | uc $level, | |
1739 | ); | |
1740 | ||
1741 | if ( $self->_logopen ) | |
1742 | { | |
1743 | print {$self->{fh}} $timestring . " - " . join(" ",@_) . "\n"; | |
1744 | } else { | |
1745 | push @{$self->{buffer}}, $timestring . " - " . join(" ",@_) . "\n"; | |
1746 | } | |
1747 | } | |
1748 | ||
1749 | =head2 DESTROY | |
1750 | ||
1751 | This method simply closes the file handle if one is open | |
1752 | ||
1753 | =cut | |
1754 | sub DESTROY | |
1755 | { | |
