529 | The DDA test in FCP is probably the single most broken protocol - only |
|
|
530 | one directory test can be outstanding at any time, and some guessing and |

531 | heuristics are involved in mangling the paths. |

|
|
534 | request, handling file reading and writing as well, and tries very hard to |
|
|
535 | do the right thing. |
|
|
536 | |
|
|
537 | Both C<$local_directory> and C<$remote_directory> must specify the same |
|
|
538 | directory - C<$local_directory> is the directory path on the client (where |
|
|
539 | L<AnyEvent::FCP> runs) and C<$remote_directory> is the directory path on |
|
|
540 | the server (where the freenet node runs). When both are running on the |
|
|
541 | same node, the paths are generally identical. |
|
|
542 | |
|
|
543 | C<$want_read> and C<$want_write> should be set to a true value when you |
|
|
544 | want to read (get) files or write (put) files, respectively. |
|
|
545 | |
|
|
546 | On error, an exception is thrown. Otherwise, C<$can_read> and |
|
|
547 | C<$can_write> indicate whether you can reaqd or write to freenet via the |
|
|
548 | directory. |

|
|
630 | |
|
|
631 | The C<AnyEvent::FCP> class keeps a request cache, where it caches all |
|
|
632 | information from requests. |
|
|
633 | |
|
|
634 | For these messages, it will store a copy of the key-value pairs, together with a C<type> slot, |
|
|
635 | in C<< $fcp->{req}{$identifier} >>: |
|
|
636 | |
|

|
|
642 | |
|
|
643 | persistent_request_modified |
|
|
644 | |
|
|
645 | This message will remove this entry: |
|
|
646 | |
|
|
647 | persistent_request_removed |
|
|
648 | |
|
|
649 | These messages get merged into the cache entry, under their |
|
|
650 | type, i.e. a C<simple_progress> message will be stored in C<< |
|

651 | $fcp->{req}{$identifier}{simple_progress} >>: |

|
672 | In addition, an event (basically a fake message) of type C<request_changed> is generated |
|
|
673 | on every change, which will be called as C<< $cb->($fcp, $kv, $type) >>, where C<$type> |
|
|
674 | is the type of the original message triggering the change, |
|
|
675 | |
|
|
676 | To fill this cache with the global queue and keep it updated, |
|
|
677 | call C<watch_global> to subscribe to updates, followed by |
|
|
678 | C<list_persistent_requests_sync>. |
|
|
679 | |
|
|
680 | $fcp->watch_global_sync_; # do not wait |
|
|
681 | $fcp->list_persistent_requests; # wait |
|
|
682 | |
|
|
683 | To get a better idea of what is stored in the cache, here is an example of |
|
|
684 | what might be stored in C<< $fcp->{req}{"Frost-gpl.txt"} >>: |
