339 | =head1 DESCRIPTION |
340 | |
b916501e |
341 | Often you want to write a persistant daemon that has a pid file, and responds |
5b9ebe08 |
342 | appropriately to Signals. This module provides a set of basic roles as an |
4327fe98 |
343 | infrastructure to do that. |
a4952679 |
344 | |
05b96f4d |
345 | =head1 CAVEATS |
346 | |
347 | When going into background MooseX::Daemonize closes all open file |
348 | handles. This may interfere with you logging because it may also close the log |
349 | file handle you want to write to. To prevent this you can either defer opening |
350 | the log file until after start. Alternatively, use can use the |
351 | 'dont_close_all_files' option either from the command line or in your .sh |
352 | script. |
353 | |
354 | Assuming you want to use Log::Log4perl for example you could expand the |
355 | MooseX::Daemonize example above like this. |
356 | |
357 | after start => sub { |
358 | my $self = shift; |
359 | return unless $self->is_daemon; |
360 | Log::Log4perl->init(\$log4perl_config); |
361 | my $logger = Log::Log4perl->get_logger(); |
362 | $logger->info("Daemon started"); |
363 | # your daemon code here ... |
364 | }; |
365 | |

367 | =head1 ATTRIBUTES |
368 | |
4327fe98 |
369 | This list includes attributes brought in from other roles as well |
370 | we include them here for ease of documentation. All of these attributes |
5b9ebe08 |
371 | are settable though L<MooseX::Getopt>'s command line handling, with the |
4327fe98 |
372 | exception of C<is_daemon>. |
373 | |
a4952679 |
374 | =over |
375 | |
4327fe98 |
376 | =item I<progname Path::Class::Dir | Str> |
a4952679 |
377 | |
4327fe98 |
378 | The name of our daemon, defaults to C<$package_name =~ s/::/_/>; |
a4952679 |
379 | |
4327fe98 |
380 | =item I<pidbase Path::Class::Dir | Str> |
a4952679 |
381 | |
1d85c76d |
382 | The base for our PID, defaults to C</var/run/> |
a4952679 |
383 | |
4327fe98 |
384 | =item I<pidfile MooseX::Daemonize::Pid::File | Str> |
a4952679 |
385 | |
1d85c76d |
386 | The file we store our PID in, defaults to C<$pidbase/$progname.pid> |
a4952679 |
387 | |
4327fe98 |
388 | =item I<foreground Bool> |
a4952679 |
389 | |
5b9ebe08 |
390 | If true, the process won't background. Useful for debugging. This option can |
b916501e |
391 | be set via Getopt's -f. |
a4952679 |
392 | |
2ecc2ccb |
393 | =item I<no_double_fork Bool> |
394 | |
395 | If true, the process will not perform the typical double-fork, which is extra |
396 | added protection from your process accidentally aquiring a controlling terminal. |
397 | More information can be found by Googling "double fork daemonize". |
398 | |
399 | =item I<ignore_zombies Bool> |
400 | |
401 | If true, the process will not clean up zombie processes. |
402 | Normally you don't want this. |
403 | |
404 | =item I<dont_close_all_files Bool> |
405 | |
406 | If true, the objects open filehandles will not be closed when daemonized. |
407 | Normally you don't want this. |
408 | |
409 | |
4327fe98 |
410 | =item I<is_daemon Bool> |
411 | |
5b9ebe08 |
412 | If true, the process is the backgrounded daemon process, if false it is the |
413 | parent process. This is useful for example in an C<after 'start' => sub { }> |
414 | block. |
e7a196e7 |
415 | |
4327fe98 |
416 | B<NOTE:> This option is explicitly B<not> available through L<MooseX::Getopt>. |
b916501e |
417 | |
4327fe98 |
418 | =item I<stop_timeout> |
b916501e |
419 | |
420 | Number of seconds to wait for the process to stop, before trying harder to kill |
4327fe98 |
421 | it. Defaults to 2 seconds. |
e7a196e7 |
422 | |

a4952679 |
436 | |
4327fe98 |
437 | =head2 Daemon Control Methods |
438 | |
5b9ebe08 |
439 | These methods can be used to control the daemon behavior. Every effort |
440 | has been made to have these methods DWIM (Do What I Mean), so that you |
441 | can focus on just writing the code for your daemon. |

443 | Extending these methods is best done with the L<Moose> method modifiers, |

4327fe98 |
452 | =item B<stop> |
a4952679 |
453 | |
454 | Stop the process matching the pidfile, and unlinks the pidfile. |

474 | =item B<init_pidfile> |
475 | |
476 | This method will create a L<MooseX::Daemonize::Pid::File> object and tell |

478 | |
479 | =item B<check> |
480 | |
5b9ebe08 |
481 | This checks to see if the daemon process is currently running by checking |
4327fe98 |
482 | the pidfile. |
a4952679 |

a4952679 |
