2104=head1 NAME
2105
2106GITCVS::log
2107
2108=head1 DESCRIPTION
2109
2110This module provides very crude logging with a similar interface to
2111Log::Log4perl
2112
2113=head1 METHODS
2114
2115=cut
2116
2117=head2 new
2118
2119Creates a new log object, optionally you can specify a filename here to
5348b6e7 2120indicate the file to log to. If no log file is specified, you can specify one
3fda8c4c
ML
2121later with method setfile, or indicate you no longer want logging with method
2122nofile.
2123
2124Until one of these methods is called, all log calls will buffer messages ready
2125to write out.
2126
2127=cut
2128sub new
2129{
2130 my $class = shift;
2131 my $filename = shift;
2132
2133 my $self = {};
2134
2135 bless $self, $class;
2136
2137 if ( defined ( $filename ) )
2138 {
2139 open $self->{fh}, ">>", $filename or die("Couldn't open '$filename' for writing : $!");
2140 }
2141
2142 return $self;
2143}
2144
2145=head2 setfile
2146
2147This methods takes a filename, and attempts to open that file as the log file.
2148If successful, all buffered data is written out to the file, and any further
2149logging is written directly to the file.
2150
2151=cut
2152sub setfile
2153{
2154 my $self = shift;
2155 my $filename = shift;
2156
2157 if ( defined ( $filename ) )
2158 {
2159 open $self->{fh}, ">>", $filename or die("Couldn't open '$filename' for writing : $!");
2160 }
2161
2162 return unless ( defined ( $self->{buffer} ) and ref $self->{buffer} eq "ARRAY" );
2163
2164 while ( my $line = shift @{$self->{buffer}} )
2165 {
2166 print {$self->{fh}} $line;
2167 }
2168}
2169
2170=head2 nofile
2171
2172This method indicates no logging is going to be used. It flushes any entries in
2173the internal buffer, and sets a flag to ensure no further data is put there.
2174
2175=cut
2176sub nofile
2177{
2178 my $self = shift;
2179
2180 $self->{nolog} = 1;
2181
2182 return unless ( defined ( $self->{buffer} ) and ref $self->{buffer} eq "ARRAY" );
2183
2184 $self->{buffer} = [];
2185}
2186
2187=head2 _logopen
2188
2189Internal method. Returns true if the log file is open, false otherwise.
2190
2191=cut
2192sub _logopen
2193{
2194 my $self = shift;
2195
2196 return 1 if ( defined ( $self->{fh} ) and ref $self->{fh} eq "GLOB" );
2197 return 0;
2198}
2199
2200=head2 debug info warn fatal
2201
2202These four methods are wrappers to _log. They provide the actual interface for
2203logging data.
2204
2205=cut
2206sub debug { my $self = shift; $self->_log("debug", @_); }
2207sub info { my $self = shift; $self->_log("info" , @_); }
2208sub warn { my $self = shift; $self->_log("warn" , @_); }
2209sub fatal { my $self = shift; $self->_log("fatal", @_); }
2210
2211=head2 _log
2212
2213This is an internal method called by the logging functions. It generates a
2214timestamp and pushes the logged line either to file, or internal buffer.
2215
2216=cut
2217sub _log
2218{
2219 my $self = shift;
2220 my $level = shift;
2221
2222 return if ( $self->{nolog} );
2223
2224 my @time = localtime;
2225 my $timestring = sprintf("%4d-%02d-%02d %02d:%02d:%02d : %-5s",
2226 $time[5] + 1900,
2227 $time[4] + 1,
2228 $time[3],
2229 $time[2],
2230 $time[1],
2231 $time[0],
2232 uc $level,
2233 );
2234
2235 if ( $self->_logopen )
2236 {
2237 print {$self->{fh}} $timestring . " - " . join(" ",@_) . "\n";
2238 } else {
2239 push @{$self->{buffer}}, $timestring . " - " . join(" ",@_) . "\n";
2240 }
2241}
2242
2243=head2 DESTROY
2244
2245This method simply closes the file handle if one is open
2246
2247=cut
2248sub DESTROY
2249{
2250 my $self = shift;
