=head1 NAME

AFS::Command::BOS - OO API to the AFS bos command

=head1 SYNOPSIS

    use AFS::Command::BOS;

    my $bos = AFS::Command::BOS->new();

    my $bos = AFS::Command::BOS->new
      (
       command			=> $path_to_your_bos_binary,
      );

    my $bos = AFS::Command::BOS->new
      (
       localauth		=> 1,
      );

=head1 DESCRIPTION

This module implements an OO API wrapper around the AFS 'bos' command.
The supported methods depend on the version of the bos binary used,
and are determined automagically.

=head1 METHODS -- Inherited

All of the following methods are inherited from the AFS::Command::Base
class.  See that documentation for details.

=head1 METHODS (with complex return values)

=head2 getdate

=over

=item Arguments

The bos help string is:

    bos getdate: get dates for programs
    Usage: bos getdate -server <machine name> -file <files to check>+ [-dir <destination dir>]
		       [-cell <cell name>] [-noauth] [-localauth]

The corresponding method invocation looks like:

    my $result = $bos->getdate
      (
       # Required arguments
       server			=> $server,
       file			=> $file, # OR [ $file1, $file2, ... ]
       # Optional arguments
       dir			=> $dir,
       cell			=> $cell,
       noauth			=> 1,
       localauth		=> 1,
      );

=item Return Values

This method returns an AFS::Object::BosServer object, which
contains one or more generic AFS::Object, one for each file
specified in the arguments.

    my $result = $bos->getdate
      (
       file				=> [ 'bosserver', 'vlserver', 'ptserver' ],
       cell				=> $cell,
      ) || die $bos->errors();

    foreach my $fileobj ( $result->getFiles() ) {
	my ($file,$date) = ($fileobj->file(),$fileobj->date());
	print "File $file has date $date\n";
    }

Each of these objects has the following attributes and methods:

B<AFS::Object::BosServer>

This object is nothing more than a container for the generic objects
for each file.  It has several methods for extracting the file objects:

    Methods			Returns
    -------			-------
    getFileNames()		a list of filenames
    getFiles()			a list of AFS::Object objects
    getFile($filename)		the AFS::Object object for $filename

B<AFS::Object>

The following attributes should always be present:

    Attributes			Values
    ----------			------
    file			fully qualified pathname to the file
    date			last modified timestamp on the file

The following attributes may be present, if there are .BAK or .OLD
versions of the file.

    Attributes			Values
    ----------			------
    bak				last modified timestamp on the .BAK file
    old				last modified timestamp on the .OLD file

=back

=head2 getlog

=over

=item Arguments

The bos help string is:

    bos getlog: examine log file
    Usage: bos getlog -server <machine name> -file <log file to examine>
		      [-cell <cell name>] [-noauth] [-localauth]

The corresponding method invocation looks like:

    my $result = $bos->getlog
      (
       # Required arguments
       server			=> $server,
       file			=> $file,
       # Optional arguments
       cell			=> $cell,
       noauth			=> 1,
       localauth		=> 1,
       # Enhanced arguments
       redirect			=> $redirect,
      );

The 'redirect' argument is the name of a file to "redirect" the log
file to.  By default, 'bos getlog' dumps the contents of the requested
file to stdout, which is not what you normally want in an application.
The value of this argument is passed directly to IO::File->open().

If this argument is not specified, then the contents of the logfile
are stashed in an attribute of the returned object.

=item Return Values

This method returns an AFS::Object::BosServer object, which
contains one attribute.

    my $result = $bos->getlog
      (
       server			=> $server,
       file			=> "/usr/afs/logs/VolserLog",
       redirect			=> "/var/tmp/VolserLog.$$",
      ) || die $bos->errors();

    my $logfile = IO::File->new("</var/tmp/VolserLog.$$") ||
      die "Unable to open logfile: $ERRNO\n";

    while ( defined($_ = $logfile->getline()) ) {
	....
    }

    # Alternately, the memory pig way:

    my $result = $bos->getlog
      (
       server			=> $server,
       file			=> "/usr/afs/logs/VolserLog",
      );

    foreach ( split(/\n+/,$result->log()) ) {
	....
    }

The object has the following attribute:

B<AFS::Object::BosServer>

    Attributes			Values
    ----------			------
    log				Contents of the logfile, or the redirect pathname

If redirect was given, then this attribute is simply same pathname.
If redirect was not given, then the value of this attribute is the
contents of the requested logfile, as a single (potentially huge)
string.

NOTE: Since this method is usually invoked to retrieve one of the AFS
logfiles, which can be enormous on heavily loaded servers that have
not been restarted in a while, use of the redirect option is strongly
encouraged.  If not used, the memory allocated to store the logfile
may be prohibitively large.  Developer beware.
