2163 | =head1 NAME | |
2164 | ||
2165 | GITCVS::log | |
2166 | ||
2167 | =head1 DESCRIPTION | |
2168 | ||
2169 | This module provides very crude logging with a similar interface to | |
2170 | Log::Log4perl | |
2171 | ||
2172 | =head1 METHODS | |
2173 | ||
2174 | =cut | |
2175 | ||
2176 | =head2 new | |
2177 | ||
2178 | Creates a new log object, optionally you can specify a filename here to | |
5348b6e7 | 2179 | indicate the file to log to. If no log file is specified, you can specify one |
3fda8c4c ML |
2180 | later with method setfile, or indicate you no longer want logging with method |
2181 | nofile. | |
2182 | ||
2183 | Until one of these methods is called, all log calls will buffer messages ready | |
2184 | to write out. | |
2185 | ||
2186 | =cut | |
2187 | sub new | |
2188 | { | |
2189 | my $class = shift; | |
2190 | my $filename = shift; | |
2191 | ||
2192 | my $self = {}; | |
2193 | ||
2194 | bless $self, $class; | |
2195 | ||
2196 | if ( defined ( $filename ) ) | |
2197 | { | |
2198 | open $self->{fh}, ">>", $filename or die("Couldn't open '$filename' for writing : $!"); | |
2199 | } | |
2200 | ||
2201 | return $self; | |
2202 | } | |
2203 | ||
2204 | =head2 setfile | |
2205 | ||
2206 | This methods takes a filename, and attempts to open that file as the log file. | |
2207 | If successful, all buffered data is written out to the file, and any further | |
2208 | logging is written directly to the file. | |
2209 | ||
2210 | =cut | |
2211 | sub setfile | |
2212 | { | |
2213 | my $self = shift; | |
2214 | my $filename = shift; | |
2215 | ||
2216 | if ( defined ( $filename ) ) | |
2217 | { | |
2218 | open $self->{fh}, ">>", $filename or die("Couldn't open '$filename' for writing : $!"); | |
2219 | } | |
2220 | ||
2221 | return unless ( defined ( $self->{buffer} ) and ref $self->{buffer} eq "ARRAY" ); | |
2222 | ||
2223 | while ( my $line = shift @{$self->{buffer}} ) | |
2224 | { | |
2225 | print {$self->{fh}} $line; | |
2226 | } | |
2227 | } | |
2228 | ||
2229 | =head2 nofile | |
2230 | ||
2231 | This method indicates no logging is going to be used. It flushes any entries in | |
2232 | the internal buffer, and sets a flag to ensure no further data is put there. | |
2233 | ||
2234 | =cut | |
2235 | sub nofile | |
2236 | { | |
2237 | my $self = shift; | |
2238 | ||
2239 | $self->{nolog} = 1; | |
2240 | ||
2241 | return unless ( defined ( $self->{buffer} ) and ref $self->{buffer} eq "ARRAY" ); | |
2242 | ||
2243 | $self->{buffer} = []; | |
2244 | } | |
2245 | ||
2246 | =head2 _logopen | |
2247 | ||
2248 | Internal method. Returns true if the log file is open, false otherwise. | |
2249 | ||
2250 | =cut | |
2251 | sub _logopen | |
2252 | { | |
2253 | my $self = shift; | |
2254 | ||
2255 | return 1 if ( defined ( $self->{fh} ) and ref $self->{fh} eq "GLOB" ); | |
2256 | return 0; | |
2257 | } | |
2258 | ||
2259 | =head2 debug info warn fatal | |
2260 | ||
2261 | These four methods are wrappers to _log. They provide the actual interface for | |
2262 | logging data. | |
2263 | ||
2264 | =cut | |
2265 | sub debug { my $self = shift; $self->_log("debug", @_); } | |
2266 | sub info { my $self = shift; $self->_log("info" , @_); } | |
2267 | sub warn { my $self = shift; $self->_log("warn" , @_); } | |
2268 | sub fatal { my $self = shift; $self->_log("fatal", @_); } | |
2269 | ||
2270 | =head2 _log | |
2271 | ||
2272 | This is an internal method called by the logging functions. It generates a | |
2273 | timestamp and pushes the logged line either to file, or internal buffer. | |
2274 | ||
2275 | =cut | |
2276 | sub _log | |
2277 | { | |
2278 | my $self = shift; | |
2279 | my $level = shift; | |
2280 | ||
2281 | return if ( $self->{nolog} ); | |
2282 | ||
2283 | my @time = localtime; | |
2284 | my $timestring = sprintf("%4d-%02d-%02d %02d:%02d:%02d : %-5s", | |
2285 | $time[5] + 1900, | |
2286 | $time[4] + 1, | |
2287 | $time[3], | |
2288 | $time[2], | |
2289 | $time[1], | |
2290 | $time[0], | |
2291 | uc $level, | |
2292 | ); | |
2293 | ||
2294 | if ( $self->_logopen ) | |
2295 | { | |
2296 | print {$self->{fh}} $timestring . " - " . join(" ",@_) . "\n"; | |
2297 | } else { | |
2298 | push @{$self->{buffer}}, $timestring . " - " . join(" ",@_) . "\n"; | |
2299 | } | |
2300 | } | |
2301 | ||
2302 | =head2 DESTROY | |
2303 | ||
2304 | This method simply closes the file handle if one is open | |
2305 | ||
2306 | =cut | |
2307 | sub DESTROY | |
2308 | { | |
