=head1 NAME
CipUX::RPC::Server - RPC server class for CipUX
=head1 VERSION
version 3.4.0.9
=head1 SYNOPSIS
use CipUX::RPC::Server;
=head1 DESCRIPTION
Provides the functions for CipUX RPC server.
=head1 ABSTRACT
The CipUX rpc server is a generic abstract class, which can be used by other
classes or scripts.
=head1 SUBROUTINES/METHODS
The following functions are implemented or supported by CipUX::RPC::Server.
=head2 BUILD
Constructor, see new.
=head2 DEMOLISH
Destructor.
=head2 new
Constructor
B<Syntax:>
my $cipux_rpc = CipUX::RPC::Server->new();
=head2 check_authentication
Check weather the login has access or not.
=head2 is_ticket_bad
Return 1 if a ticket is OK otherwise 0;
=head2 signal_handler
Install signal_handler alias time to die.
B<Syntax:>
$server->signal_handler({});
=head2 answer_requests
Answer Requests.
B<Syntax:>
$server->answer_requests({
port=>8000,
address=>'localhost',
reuse=>0,
proto=>'tcp',
meth_hr=>TODO
task_hr=>TODO
});
=head2 check_access_to_task
Check the access for login to a task.
=head2 check_access_to_rpc_intern
Check the access for login to the rpc_intern section.
=head2 check_access_to_cat_module
Check the access for login to a CAT module.
=head2 error
Construct an error message.
=head2 evaluate_access
Evaluate the access to login or a given user depending on the sub command
(subcmd) of rpc_info or rpc_intern for one or more realms. Known realms are:
task, cat_module, rpc_intern.
=head2 update_task
Check and update tasks entries.
=head2 update_cat_module
Check and update CAT modules entries.
=head2 log2syslog
Log a given message to syslog.
=head2 get_config
Return the value for a given configuration variable.
=head2 rpc_list_functions
List the rpc functions.
=head2 rpc_start
Start the RPC server.
B<Syntax:>
$server->rpc_start({});
=head2 ping
The function 'ping' is for testing the connection. It requires not to log in
and no arguments. It returns 'OK'.
=head2 version
Return the CipUX version.
=head2 sum
The function 'sum' is for testing the connection. It requires not to log in and
2 arguments. It returns the sum of the arguments as a hash reference with a
single line.
=head2 login
Perform a login.
=head2 logout
Perform a logout.
=head2 session
Check the ticket and if it is valid update and return a new ticket.
=head2 ttl
Return the Time To Live. Default 900 seconds.
=head2 rpc_task
Execute a CipUX::Task.
=head2 rpc_info
Execute a rpc_info sub-command.
=head3 task_access

=head3 rpc_intern_access
Needs parameter: COMMAND
=head3 rpc_intern_access_survey
Needs parameter: COMMAND [COMMAND] ...
=head2 rpc_intern
Execute a rpc_intern sub-command.
=head3 ttl
Prints current TTL in seconds
=head3 cat_module_cache_size
Prints current cat module cache size
=head3 rpc_intern_cache_size
Prints current rpc intern cache size
=head3 task_cache_size
Prints current task_cache_size of cache
=head3 user_task_access
Needs parameter: USER TASK
=head3 user_task_access_survey
Needs parameter: $USER TASK [TASK] ...
=head3 user_cat_module_access
Needs parameter: USER MODULE

Needs parameter: USER MODULE [MODULE] ...
=head3 user_rpc_intern_access
Needs parameter: USER COMMAND
=head3 user_rpc_intern_access_survey
Needs parameter: USER COMMAND [COMMAND] ...
=head3 flush_cache
Flush RPC server RBAC cache
=head1 Public XML-RPC functions.
All the following CipUX::Task methods are public. Public means that they could
be executed remotely. Public means not that everybody can do this remotely.
There are two kinds of public functions:
(1) Functions without authorization
- login
- ping
- sum
(2) Every other function is available only after using 'login' function, with a
uid as first parameter and a valid ticket as second parameter.
Examples (pseudo code):
- (reference to user list) = cipux_task_list_users( uid, ticket );
- (true|false) = logout( uid, ticket );
- (new ticket|false) = session( uid, ticket );
If the uid do not match, or the uid has not the authorization to use the
function, or the group of the uid has not the authorization to use the
function, or the ticket is expired, or the ticket is not valid the request will
not be fulfilled.
In other words: if the uid match and has the right and the role also has the
right and the ticket is valid and is not expired, the request will be executed.
To see real examples have a look at CipUX::RPC::Client client.
