GEARMAND(1p)						User Contributed Perl Documentation					      GEARMAND(1p)

NAME

       gearmand - Gearman client/worker connector.

SYNOPSIS

	gearmand --daemon

DESCRIPTION

       This is the main executable for Gearman::Server.  It provides command-line configuration of port numbers, pidfiles, and daemonization.

OPTIONS

       --daemonize / -d
	   Make the daemon run in the background (good for init.d scripts, bad for running under daemontools/supervise).

       --port=7003 / -p 7003
	   Set the port number, defaults to 7003.

       --pidfile=/some/dir/gearmand.pid
	   Write a pidfile when starting up

       --debug=1
	   Enable debugging (currently the only debug output is when a client or worker connects).

       --accept=10
	   Number of new connections to accept each time we see a listening socket ready. This doesn't usually need to be tuned by anyone, however
	   in dire circumstances you may need to do it quickly.

       --wakeup=3
	   Number of workers to wake up per job inserted into the queue.

	   Zero(0) is a perfectly acceptable answer, and can be used if you don't care much about job latency.  This would bank on the base idea
	   of a worker checking in with the server every so often.

	   Negative One (-1) indicates that all sleeping workers should be woken up.

	   All other negative numbers will cause the server to throw exception and not start.

       --wakeup-delay=
	   Time interval before waking up more workers (the value specified by --wakeup) when jobs are still in the queue.

	   Zero(0) means go as fast as possible, but not all at the same time. Similar to -1 on --wakeup, but is more cooperative in gearmand's
	   multitasking model.

	   Negative One (-1) means that this event won't happe, so only the initial workers will be woken up to handle jobs in the queue.

NAME

       Thread::Pool::Simple - A simple thread-pool implementation

SYNOPSIS

	 use Thread::Pool::Simple;

	 my $pool = Thread::Pool::Simple->new(
			min => 3,	    # at least 3 workers
			max => 5,	    # at most 5 workers
			load => 10,	    # increase worker if on average every worker has 10 jobs waiting
			init => [&init_handle, $arg1, $arg2, ...]   # run before creating worker thread
			pre => [&pre_handle, $arg1, $arg2, ...]   # run after creating worker thread
			do => [&do_handle, $arg1, $arg2, ...]	   # job handler for each worker
			post => [&post_handle, $arg1, $arg2, ...] # run before worker threads end
			passid => 1,	    # whether to pass the job id as the first argument to the &do_handle
			lifespan => 10000,  # total jobs handled by each worker
		      );

	 my ($id1) = $pool->add(@arg1); # call in list context
	 my $id2 = $pool->add(@arg2);	# call in scalar conetxt
	 $pool->add(@arg3)		# call in void context

	 my @ret = $pool->remove($id1); # get result (block)
	 my $ret = $pool->remove_nb($id2); # get result (no block)

	 $pool->cancel($id1);		# cancel the job
	 $pool->cancel_all();		# cancel all jobs

	 $pool->join(); 		# wait till all jobs are done
	 $pool->detach();		# don't wait.

DESCRIPTION

       "Thread::Pool::Simple" provides a simple thread-pool implementaion without external dependencies outside core modules.

       Jobs can be submitted to and handled by multi-threaded `workers' managed by the pool.
