NAME

Gearman::Driver::Job - Handles the POE magic

DESCRIPTION

This class is responsible for starting/stopping processes as well as handling all pipes (STDOUT/STDERR/STDIN) of the processes. All events are written to a logfile. Possible events are:

  • Starting processes

  • STDOUT of processes

  • STDERR of processes

  • Stopping processes

The current interface may only be interesting for people subclassing Gearman::Driver or for people writing commands/extensions for Gearman::Driver::Console.

ATTRIBUTES

driver

Reference to the Gearman::Driver instance.

name

The job's name.

method

Code reference which is run called by Gearman::XS::Worker. Actually it's not called directly by it, but in a wrapped coderef.

worker

Reference to the worker object.

max_processes

Maximum number of concurrent processes this job may have.

min_processes

Minimum number of concurrent processes this job may have.

encode

This may be set to a method name which is implemented in the worker class or any subclass. If the method is not available, it will fail. The returned value of the job method is passed to this method and the return value of this method is sent back to the Gearman server.

See also: "Encode" in Gearman::Driver::Worker.

decode

This may be set to a method name which is implemented in the worker class or any subclass. If the method is not available, it will fail. The workload from Gearman::XS::Job is passed to this method and the return value is passed as argument $workload to the job method.

See also: "Decode" in Gearman::Driver::Worker.

processes

This attribute stores a key/value pair containing: $pid => $job

It provides following methods:

  • count_processes()

  • delete_process($pid)

  • get_process($pid)

  • get_processes()

  • get_pids()

  • set_process($pid = $job)>

gearman

Instance of Gearman::Driver::Adaptor.

session

Instance of POE::Session.

lastrun

Each time this job is called it stores time() in this attribute.

This depends on "extended_status" in Gearman::Driver.

lasterror

Each time this job failed it stores time() in this attribute.

This depends on "extended_status" in Gearman::Driver.

lasterror_msg

Each time this job failed it stores the error message in this attribute.
