=head1 NAME |
|
|
|
GITCVS::log |
|
|
|
=head1 DESCRIPTION |
|
|
|
This module provides very crude logging with a similar interface to |
|
Log::Log4perl |
|
|
|
=head1 METHODS |
|
|
|
=cut |
|
|
|
=head2 new |
|
|
|
Creates a new log object, optionally you can specify a filename here to |
|
indicate the file to log to. If no log file is specified, you can specify one |
|
later with method setfile, or indicate you no longer want logging with method |
|
nofile. |
|
|
|
Until one of these methods is called, all log calls will buffer messages ready |
|
to write out. |
|
|
|
=cut |
|
sub new |
|
{ |
|
my $class = shift; |
|
my $filename = shift; |
|
|
|
my $self = {}; |
|
|
|
bless $self, $class; |
|
|
|
if ( defined ( $filename ) ) |
|
{ |
|
open $self->{fh}, ">>", $filename or die("Couldn't open '$filename' for writing : $!"); |
|
} |
|
|
|
return $self; |
|
} |
|
|
|
=head2 setfile |
|
|
|
This methods takes a filename, and attempts to open that file as the log file. |
|
If successful, all buffered data is written out to the file, and any further |
|
logging is written directly to the file. |
|
|
|
=cut |
|
sub setfile |
|
{ |
|
my $self = shift; |
|
my $filename = shift; |
|
|
|
if ( defined ( $filename ) ) |
|
{ |
|
open $self->{fh}, ">>", $filename or die("Couldn't open '$filename' for writing : $!"); |
|
} |
|
|
|
return unless ( defined ( $self->{buffer} ) and ref $self->{buffer} eq "ARRAY" ); |
|
|
|
while ( my $line = shift @{$self->{buffer}} ) |
|
{ |
|
print {$self->{fh}} $line; |
|
} |
|
} |
|
|
|
=head2 nofile |
|
|
|
This method indicates no logging is going to be used. It flushes any entries in |
|
the internal buffer, and sets a flag to ensure no further data is put there. |
|
|
|
=cut |
|
sub nofile |
|
{ |
|
my $self = shift; |
|
|
|
$self->{nolog} = 1; |
|
|
|
return unless ( defined ( $self->{buffer} ) and ref $self->{buffer} eq "ARRAY" ); |
|
|
|
$self->{buffer} = []; |
|
} |
|
|
|
=head2 _logopen |
|
|
|
Internal method. Returns true if the log file is open, false otherwise. |
|
|
|
=cut |
|
sub _logopen |
|
{ |
|
my $self = shift; |
|
|
|
return 1 if ( defined ( $self->{fh} ) and ref $self->{fh} eq "GLOB" ); |
|
return 0; |
|
} |
|
|
|
=head2 debug info warn fatal |
|
|
|
These four methods are wrappers to _log. They provide the actual interface for |
|
logging data. |
|
|
|
=cut |
|
sub debug { my $self = shift; $self->_log("debug", @_); } |
|
sub info { my $self = shift; $self->_log("info" , @_); } |
|
sub warn { my $self = shift; $self->_log("warn" , @_); } |
|
sub fatal { my $self = shift; $self->_log("fatal", @_); } |
|
|
|
=head2 _log |
|
|
|
This is an internal method called by the logging functions. It generates a |
|
timestamp and pushes the logged line either to file, or internal buffer. |
|
|
|
=cut |
|
sub _log |
|
{ |
|
my $self = shift; |
|
my $level = shift; |
|
|
|
return if ( $self->{nolog} ); |
|
|
|
my @time = localtime; |
|
my $timestring = sprintf("%4d-%02d-%02d %02d:%02d:%02d : %-5s", |
|

|
$time[4] + 1, |
|
$time[3], |
|
$time[2], |
|
$time[1], |
|
$time[0], |
|
uc $level, |
|
); |
|
|
|
if ( $self->_logopen ) |
|
{ |
|
print {$self->{fh}} $timestring . " - " . join(" ",@_) . "\n"; |
|
} else { |
|
push @{$self->{buffer}}, $timestring . " - " . join(" ",@_) . "\n"; |
|
} |
|
} |
|
|
|
=head2 DESTROY |
|
|
|
This method simply closes the file handle if one is open |
|
|
|
=cut |
|
sub DESTROY |
|
{ |
|
my $self = shift; |
|
|
|
if ( $self->_logopen ) |
