=head1 DESCRIPTION |
473
|
|
|
|
|
|
|
|
474
|
|
|
|
|
|
|
If you need nonblocking access to an external program, or want to execute |
475
|
|
|
|
|
|
|
some blocking code in a separate process, but you don't want to write a |
476
|
|
|
|
|
|
|
wrapper module or some L boilerplate code, |
477
|
|
|
|
|
|
|
then POE::Quickie can help. You just specify what you're interested in |
478
|
|
|
|
|
|
|
(stdout, stderr, and/or exit code), and POE::Quickie will handle the rest in |
479
|
|
|
|
|
|
|
a sensible way. |
480
|
|
|
|
|
|
|
|
481
|
|
|
|
|
|
|
It has some convenience features, such as killing processes after a timeout, |
482
|
|
|
|
|
|
|
and storing process-specific context information which will be delivered with |
483
|
|
|
|
|
|
|
every event. |
484
|
|
|
|
|
|
|
|
485
|
|
|
|
|
|
|
There is also an even lazier API which suspends the execution of your event |
486
|
|
|
|
|
|
|
handler and gives control back to POE while your task is running, the same |
487
|
|
|
|
|
|
|
way L does. This is provided by the |
488
|
|
|
|
|
|
|
L|/FUNCTIONS> functions which are exported by default. |

|
|
|
|
|
Constructs a POE::Quickie object. You only need to do this if you want to |
495
|
|
|
|
|
|
|
specify any of the parameters below, since a POE::Quickie object will be |
496
|
|
|
|
|
|
|
constructed automatically when it is needed. The rest of the methods can |
497
|
|
|
|
|
|
|
be called on the object (C<< $object->run() >>) or as class methods |
498
|
|
|
|
|
|
|
(C<< POE::Quickie->run() >>). You can safely let the object go out of scope; |
499
|
|
|
|
|
|
|
POE::Quickie will continue to run your processes until they finish. |
500
|
|
|
|
|
|
|
|
501
|
|
|
|
|
|
|
Takes 3 optional parameters: B<'debug'>, B<'default'>, and B<'trace'>. These |
502
|
|
|
|
|
|
|
will be passed to the object's L constructor. See |
503
|
|
|
|
|
|
|
its documentation for details. |

|
|
|
This method spawns a new child process. It returns its process id. |
508
|
|
|
|
|
|
|
|
509
|
|
|
|
|
|
|
You can either call it with a single argument (string, arrayref, or coderef), |
510
|
|
|
|
|
|
|
which will used as the B<'Program'> argument, or you can supply the following |
511
|
|
|
|
|
|
|
key-value pairs: |
512
|
|
|
|
|
|
|
|
513
|
|
|
|
|
|
|
B<'Program'> (required), will be passed to directly to |
514
|
|
|
|
|
|
|
L's constructor. |
515
|
|
|
|
|
|
|
|
516
|
|
|
|
|
|
|
B<'ProgramArgs'> (optional), will be passed directly to |
517
|
|
|
|
|
|
|
L's constructor. |
518
|
|
|
|
|
|
|
|
519
|
|
|
|
|
|
|
B<'Input'> (optional), a string containing the input to the process. This |
520
|
|
|
|
|
|
|
string, if provided, will be sent immediately to the child, and its stdin |
521
|
|
|
|
|
|
|
will then be shut down. B no processing will be done on the data |
522
|
|
|
|
|
|
|
before it is sent. For instance, if you are executing a program which expects |
523
|
|
|
|
|
|
|
line-based input, be sure to end your input with a newline. |
524
|
|
|
|
|
|
|
|
525
|
|
|
|
|
|
|
B<'StdoutEvent'> (optional), the event for delivering lines from the |
526
|
|
|
|
|
|
|
process' STDOUT. If you don't supply this, they will be printed to the main |
527
|
|
|
|
|
|
|
process's STDOUT. To explicitly ignore them, set this to C. |
528
|
|
|
|
|
|
|
|
529
|
|
|
|
|
|
|
B<'StderrEvent'> (optional), the event for delivering lines from the |
530
|
|
|
|
|
|
|
process' STDERR. If you don't supply this, they will be printed to the main |
531
|
|
|
|
|
|
|
process' STDERR. To explicitly ignore them, set this to C. |
532
|
|
|
|
|
|
|
|
533
|
|
|
|
|
|
|
B<'ExitEvent'> (optional), the event to be called when the process has exited. |
534
|
|
|
|
|
|
|
If you don't supply this, a warning indicating the exit code will be printed |
535
|
|
|
|
|
|
|
if it is nonzero. To explicitly ignore it, set this to C. |
536
|
|
|
|
|
|
|
|
537
|
|
|
|
|
|
|
B<'ResultEvent'> (optional), like 'ExitEvent', but it will also contain all |
538
|
|
|
|
|
|
|
the stdout/stderr generated by the child process. |
539
|
|
|
|
|
|
|
|
540
|
|
|
|
|
|
|
B<'Context'> (optional), a variable which will be sent back to you with every |
541
|
|
|
|
|
|
|
event. If you pass a reference, that same reference will be delivered back |
542
|
|
|
|
|
|
|
to you later (not a copy), so you can update it as you see fit. |
543
|
|
|
|
|
|
|
|
544
|
|
|
|
|
|
|
B<'Timeout'> (optional), a timeout in seconds after which the process will |
545
|
|
|
|
|
|
|
be forcibly L if it is still running. There is |
546
|
|
|
|
|
|
|
no timeout by default. |
547
|
|
|
|
|
|
|
|
548
|
|
|
|
|
|
|
B<'AltFork'> (optional), if true, a new instance of the active Perl |
549
|
|
|
|
|
|
|
interpreter (L|perlvar>) will be launched with B<'Program'> (which |
550
|
|
|
|
|
|
|
must be a string) as the code argument (L|perlrun>), and the current |
551
|
|
|
|
|
|
|
L|perlvar> passed as include arguments (L|perlrun>). Default |
552
|
|
|
|
|
|
|
is false. |
553
|
|
|
|
|
|
|
|
554
|
|
|
|
|
|
|
All other arguments will be passed to POE::Wheel::Run's |
555
|
|
|
|
|
|
|
L|POE::Wheel::Run/new> method. Useful if you want to specify the |
556
|
|
|
|
|
|
|
input/output filters and such. |

This L all processes which POE::Quickie is |
561
|
|
|
|
|
|
|
managing for your session. Takes one optional argument, a signal name (e.g. |
562
|
|

B<'SIGTERM'>). |

636
|
|
|
|
|
|
|
The following functions are modeled after the ones provided by |
637
|
|
|
|
|
|
|
L. They will not return until the executed |
638
|
|
|
|
|
|
|
process has exited. However, |
639
|
|
|
|
|
|
|
L|POE::Kernel/run_one_timeslice> in POE::Kernel will be |
640
|
|
|
|
|
|
|
called in the meantime, so the rest of your application will continue to run. |
641
|
|
|
|
|
|
|
|
642
|
|
|
|
|
|
|
They all take the same arguments as the L|/run> method, except for the |
643
|
|
|
|
|
|
|
B<'*Event'> and B<'Context'> arguments. |
644
|
|
|
|
|
|
|
|
645
|
|
|
|
|
|
|
B Since these functions block, you must be careful not to call them in |
646
|
|
|
|
|
|
|
event handlers which were executed with C<< $poe_kernel->call() >> by other |
647
|
|
|
|
|
|
|
sessions, so you don't hold them up. A simple way to avoid that is to |
648
|
|
|
|
|
|
|
C or C a new event to your session and do it from there. |

child process. |

Returns 3 values: an array of all stdout chunks, an array of all stderr |
658

|
|
|
chunks, and the exit code (L|perlvar>) of the child process. In addition, |
659
|

it will echo the stdout/stderr to your process' stdout/stderr. |
