| # repository and check it out to 1dir in the working directory. Now suppose |

| # the co request to update it. Without using expand-modules, the client |
| # would have two bad choices: it could either send information about all |
| # working directories under the current directory, which could be |
| # unnecessarily slow, or it could be ignorant of the fact that aliasmodule |
| # stands for 1dir, and neglect to send information for 1dir, which would |

| =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} ); |
| |
