570 | =head1 PERLMULTICORE SUPPORT |
|
|
571 | |
|
|
572 | This module supports the perlmulticore standard (see |
|
|
573 | L<http://perlmulticore.schmorp.de/> for more info) for the following |
|
|
574 | functions - generally these are functions accessing the disk and/or using |
|
|
575 | considerable CPU time: |
|
|
576 | |
|
|
577 | LoadFile |
|
|
578 | $item->decode |
|
|
579 | $item->decode_temp |
|
|
580 | $item->remove_temp |
|
|
581 | $item->info |
|
|
582 | |
|
|
583 | The perl interpreter will be reacquired/released on every callback |
|
|
584 | invocation, so for performance reasons, callbacks should be avoided if |
|
|
585 | that is costly. |
|
|
586 | |
|
|
587 | Future versions might enable multicore support for more functions. |
|
|
588 | |
|
|
589 | =head1 BUGS AND LIMITATIONS |
|
|
590 | |
|
|
591 | The original uulib library this module uses was written at a time where |
|
|
592 | main memory of measured in megabytes and buffer overflows as a security |
|
|
593 | thign didn't exist. While a lot of security fixes have been applied over |
|
|
594 | the years (includign some defense in depth mechanism that can shield |
|
|
595 | against a lot of as-of-yet undetected bugs), using this library for |
|
|
596 | security purposes requires care. |
|
|
597 | |
|
|
598 | Likewise, file sizes when the uulib library was written were tiny compared |
|
|
599 | to today, so do not expect this library to handle files larger than 2GB. |
|
|
600 | |
|
|
601 | Lastly, this module uses a very "C-like" interface, which means it doesn't |
|
|
602 | protect you from invalid points as you might expect from "more perlish" |
|
|
603 | modules - for example, accessing a file item object after callinbg |
|
|
604 | C<CleanUp> will likely result in crashes, memory corruption, or worse. |
