git-update-ref writes into the lockfile, and renames it afterwards. Like commit v1.3.0-rc3~22, it is not only cleaner, but also helps with shared setups: every developer can have a different primary group; what matters is that $GIT_DIR/refs/heads has to be writable by a group you are in.

#     which working directories the server needs to know about in order to
 | 
						|
#     handle a checkout of the specified modules. For example, suppose that the
 | 
						|
#     server has a module defined by
 | 
						|
#   aliasmodule -a 1dir
 | 
						|
#     That is, one can check out aliasmodule and it will take 1dir in the
 | 
						|
#     repository and check it out to 1dir in the working directory. Now suppose
 | 
						|
#     the client already has this module checked out and is planning on using
 | 
						|
#     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
 | 
						|
#     lead to incorrect operation. With expand-modules, the client would first
 |

 | 
						|
 | 
						|
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 $timestring = sprintf("%4d-%02d-%02d %02d:%02d:%02d : %-5s",
 | 
						|
        $time[5] + 1900,
 | 
						|
        $time[4] + 1,
 | 
						|
        $time[3],

        $time[2],
 |

        $time[1],

						|
        $time[0],
 | 
						|
        uc $level,
 | 
						|
    );
 | 
						|
 | 
						|
    if ( $self->_logopen )
 | 
						|
    {
 | 
						|
        print {$self->{fh}} $timestring . " - " . join(" ",@_) . "\n";
 | 
						|
    } else {

        push @{$self->{buffer}}, $timestring . " - " . join(" ",@_) . "\n";
 | 
						|
    }
 | 
						|
}
 | 
						|

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