NAME

Rex::Task - The Task Object

DESCRIPTION

The Task Object. Typically you only need this class if you want to manipulate tasks after their initial creation.

SYNOPSIS

 use Rex::Task;
 
 # create a new task
 my $task = Rex::Task->new(name => "testtask");
 $task->set_server("remoteserver");
 $task->set_code(sub { say "Hello"; });
 $task->modify("no_ssh", 1);
 
 # retrieve an existing task
 use Rex::TaskList;
 
 my $existing_task = Rex::TaskList->get_task('my_task');

METHODS

new

This is the constructor.

 $task = Rex::Task->new(
   func => sub { some_code_here },
   server => [ @server ],
   desc => $description,
   no_ssh => $no_ssh,
   hidden => $hidden,
   auth => {
     user      => $user,
     password   => $password,
     private_key => $private_key,
     public_key  => $public_key,
   },
   before => [sub {}, sub {}, ...],
   after  => [sub {}, sub {}, ...],
   around => [sub {}, sub {}, ...],
   before_task_start => [sub {}, sub {}, ...],
   after_task_finished => [sub {}, sub {}, ...],
   name => $task_name,
   executor => Rex::Interface::Executor->create,
   opts => {key1 => val1, key2 => val2, ...},
   args => [arg1, arg2, ...],
 );

connection

Returns the current connection object.

executor

Returns the current executor object.

hidden

Returns true if the task is hidden. (Should not be displayed on ,,rex -T''.)

server

Returns the servers on which the task should be executed as an ArrayRef.

set_server(@server)

With this method you can set new servers on which the task should be executed on.

delete_server

Delete every server registered to the task.

current_server

Returns the current server on which the tasks gets executed right now.

desc

Returns the description of a task.

set_desc($description)

Set the description of a task.

is_remote

Returns true (1) if the task will be executed remotely.

is_local

Returns true (1) if the task gets executed on the local host.

is_http

Returns true (1) if the task gets executed over http protocol.

is_https

Returns true (1) if the task gets executed over https protocol.

is_openssh

Returns true (1) if the task gets executed with openssh.

want_connect

Returns true (1) if the task will establish a connection to a remote system.

get_connection_type

This method tries to guess the right connection type for the task and returns it.

Current return values are below:

• SSH: connect to the remote server using Net::SSH2

• OpenSSH: connect to the remote server using Net::OpenSSH

• Local: runs locally (without any connections)

• HTTP: uses experimental HTTP connection

• HTTPS: uses experimental HTTPS connection

• Fake: populate the connection properties, but do not connect

  So you can use this type to iterate over a list of remote hosts, but don't let rex build a connection. For example if you want to use Sys::Virt or other modules.

modify($key, $value)

With this method you can modify values of the task.

rethink_connection

Deletes current connection object.

user

Returns the username the task will use.

set_user($user)

Set the username of a task.

password

Returns the password that will be used.

set_password($password)

Set the password of the task.

name

Returns the name of the task.

code

Returns the code of the task.

set_code(\&code_ref)

Set the code of the task.

run_hook($server, $hook)

This method is used internally to execute the specified hooks.

set_auth($key, $value)

Set the authentication of the task.

 $task->set_auth("user", "foo");
 $task->set_auth("password", "bar");

merge_auth($server)

Merges the authentication information from $server into the task. Tasks authentication information have precedence.

get_sudo_password

Returns the sudo password.

parallelism

Get the parallelism count of a task.

set_parallelism($count)

Set the parallelism of the task.

connect($server)

Initiate the connection to $server.

disconnect

Disconnect from the current connection.

get_data

Dump task data.

run($server, %options)

Run the task on $server, with %options.

modify_task($task, $key => $value)

Modify $task, by setting $key to $value.

is_task

Returns true(1) if the passed object is a task.

get_tasks

Returns list of tasks.

get_desc

Returns description of task.

exit_on_connect_fail

Returns true if rex should exit on connect failure.

set_exit_on_connect_fail

Sets if rex should exit on connect failure.

get_args

Returns arguments of task.

get_opts

Returns options of task.

set_args

Sets arguments for task.

set_opt

Sets an option for task.

set_opts

Sets options for task.

clone

Clones a task.
