=head1 NAME

Amanda::Logfile - manage Amanda trace logs

=head1 SYNOPSIS

  use Amanda::Logfile qw(:logtype_t); # XXX change
  use Amanda::Config qw( :getconf config_dir_relative );

  for my $logfile (Amanda::Logfile::find_log()) {
    $logfile = config_dir_relative(getconf($CNF_LOGDIR)) . "/" . $logfile;

    my $hdl = Amanda::Logfile::open_logfile($logfile);
    while (my ($type, $prog, $str) = Amanda::Logfile::get_logline($hdl)) {
      if ($type == $L_INFO) {
        my $pname = Amanda::Logfile::program_t_to_string($prog);
        print "Found info line from $pname: $str\n";
      }
    }
    Amanda::Logfile::close_logfile($log);

    my @dumps = Amanda::Logfile::search_logfile("TapeLabel-001", "19780615", $logfile);

    my @matching = Amanda::Logfile::dumps_match([@dumps], "myhost", "/usr", undef, undef, 0);
    for my $dump (@matching) {
      print "$dump->{'label'}:$dump->{'filenum'} = $dump->{'hostname'}:$dump->{'disk'}\n";
    }
  }

=head1 API STATUS

Stabilizing

=head1 RAW LOGFILE ACCESS

This section corresponds to the C C<logfile> module. 

Raw access to logfiles is accomplished by opening a logfile and
fetching log lines one by one via the C<get_logline> function.

A log line is represented by a list C<($type, $prog, $string)>
where C<$type> is one of the C<L_*> constants (available in export
tag C<logtype_t>), C<$prog> is one of the C<P_*> constants (available
in export tag C<program_t>), and C<$str> is the remainder of the line.

Both families of constants can be converted to symbolic names with
C<logtype_t_to_string> and C<program_t_to_string>, respectively.

=head2 FUNCTIONS

=over

=item C<open_logfile($filename)>

Opens a logfile for reading, returning an opaque log file handle.

=item C<close_logfile($handle)>

Closes a log file handle.

=item C<get_logline($handle)>

Return a list as described above representing the next log line in
C<$handle>, or nothing at the end of the logfile. 

=back

All of these functions can be imported by name if desired.

=head1 Amanda::Find::find_result_t objects

These objects contain information about dumps, as read from logfiles.
Instance variables are:

=over

=item C<$timestamp>

=item C<$hostname>

=item C<$diskname>

=item C<$level>

=item C<$label>

=item C<$filenum>

=item C<$status>

=item C<$partnum>

=back

=head1 HIGHER-LEVEL FUNCTIONS

Functions in this section extract information from logfiles.

=over

=item C<find_log()>

Return a list of logfiles for active tapes.  The tapelist must be loaded before
this function is called (see L<Amanda::Tapelist>).

=item C<search_logfile($label, $datestamp, $logfile, $add_missing_disks)>

Return all results in C<$logfile> matching C<$label> and C<$datestamp>.
If C<$add_missing_disks> is true, then any disks in the logfile
not present in the disklist are added to the disklist; otherwise,
such dumps are skipped.

=item C<dumps_match([@results], $hostname, $diskname, $datestamp, $level, $ok)>

Return a filtered version of C<@results> containing only results that match the 
given expressions.  If C<$ok> is true, don't match partial results.  Note that
C<$level> is given as a string, since it is a match expression.

All of these functions can be imported by name.
