# the co request to update it. Without using expand-modules, the client

|
|
# 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;

|
|
{
|
|
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;
|

$time[2],
|

$time[1],

|

} 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;

This function takes a filename (with path) argument and returns an arrayofarrays

containing revision,filehash,commithash ordered by revision descending.
|
|
|
|
This version of gethistory skips deleted entries -- so it is useful for annotate.
|
|
The 'dense' part is a reference to a '--dense' option available for git-rev-list
|
|
and other git tools that depend on it.
