Just by sending the files in an ordered fashion, clients can process them much faster. And we can optimize our check of whether we created this directory already -- faster. Timings for a checkout on a commandline cvs client for a project with ~13K files totalling ~100MB: Unsorted: 603.12 real 16.89 user 42.88 sys Sorted: 298.19 real 26.37 user 42.42 sys

=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 specifiy 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
|
|

|
|
}
|
|
|
|
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
|

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
|

|

|
|
=head2 _logopen
|
|
|
|
Internal method. Returns true if the log file is open, false otherwise.
|
|
|
|
=cut
|

sub _logopen
|
|

|
|
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 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

=head2 DESTROY
|
|
|
|
This method simply closes the file handle if one is open
|
