304 | =head2 FCP REQUESTS |
|
|
305 | |
|
|
306 | The following methods implement various requests. Most of them map |
|
|
307 | directory to the FCP message of the same name. The added benefit of |
|
|
308 | these over sending requests yourself is that they handle the necessary |
|
|
309 | serialisation, protocol quirks, and replies. |
|
|
310 | |
|
|
311 | All of them exist in two versions, the variant shown in this manpage, and |
|
|
312 | a variant with an extra C<_> at the end, and an extra C<$cb> argument. The |
|
|
313 | version as shown is I<synchronous> - it will wait for any replies, and |
|
|
314 | either return the reply, or croak with an error. The underscore variant |
|
|
315 | returns immediately and invokes one or more callbacks or condvars later. |
|
|
316 | |
|
|
317 | For example, the call |
|
|
318 | |
|
|
319 | $info = $fcp->get_plugin_info ($name, $detailed); |
|
|
320 | |
|
|
321 | Also comes in this underscore variant: |
|
|
322 | |
|
|
323 | $fcp->get_plugin_info_ ($name, $detailed, $cb); |
|
|
324 | |
|
|
325 | You can thinbk of the underscore as a kind of continuation indicator - the |
|
|
326 | normal function waits and returns with the data, the C<_> indicates that |
|
|
327 | you pass the continuation yourself, and the continuation will be invoked |
|
|
328 | with the results. |
|
|
329 | |
|
|
330 | This callback/continuation argument (C<$cb>) can come in three forms itself: |
|
|
331 | |
|
|
332 | =over 4 |
|
|
333 | |
|
|
334 | =item A code reference (or rather anything not matching some other alternative) |
|
|
335 | |
|
|
336 | This code reference will be invoked with the result on success. On an |
|
|
337 | error, it will die (in the event loop) with a backtrace of the call site. |
|
|
338 | |
|
|
339 | This is a popular choice, but it makes handling errors hard - make sure |
|
|
340 | you never generate protocol errors! |
|
|
341 | |
|
|
342 | =item A condvar (as returned by e.g. C<< AnyEvent->condvar >>) |
|
|
343 | |
|
|
344 | When a condvar is passed, it is sent (C<< $cv->send ($results) >>) the |
|
|
345 | results when the request has finished. Should an error occur, the error |
|
|
346 | will instead result in C<< $cv->croak ($error) >>. |
|
|
347 | |
|
|
348 | This is also a popular choice. |
|
|
349 | |
|
|
350 | =item An array with two callbacks C<[$success, $failure]> |
|
|
351 | |
|
|
352 | The C<$success> callback will be invoked with the results, while the |
|
|
353 | C<$failure> callback will be invoked on any errors. |
|
|
354 | |
|
|
355 | =item C<undef> |
|
|
356 | |
|
|
357 | This is the same thing as specifying C<sub { }> as callback, i.e. on |
|
|
358 | success, the results are ignored, while on failure, you the module dies |
|
|
359 | with a backtrace. |
|
|
360 | |
|
|
361 | This is good for quick scripts, or when you really aren't interested in |
|
|
362 | the results. |

739 | =head2 REQUEST CACHE |
|
|
740 | |
|
|
741 | The C<AnyEvent::FCP> class keeps a request cache, where it caches all |
|
|
742 | information from requests. |
|
|
743 | |
|
|
744 | For these messages, it will store a copy of the key-value pairs, together with a C<type> slot, |
|
|
745 | in C<< $fcp->{req}{$identifier} >>: |
|
|
746 | |
|
|
747 | persistent_get |
|
|
748 | persistent_put |
|
|
749 | persistent_put_dir |
|
|
750 | |
|
|
751 | This message updates the stored data: |
|
|
752 | |
|
|
753 | persistent_request_modified |
|
|
754 | |
|
|
755 | This message will remove this entry: |
|
|
756 | |
|
|
757 | persistent_request_removed |
|
|
758 | |
|
|
759 | These messages get merged into the cache entry, under their |
|
|
760 | type, i.e. a C<simple_progress> message will be stored in C<< |
|
|
761 | $fcp->{req}{$identifier}{simple_progress} >>: |
|
|
762 | |
|
|
763 | simple_progress # get/put |
|
|
764 | |
|
|
765 | uri_generated # put |
|
|
766 | generated_metadata # put |
|
|
767 | started_compression # put |
|
|
768 | finished_compression # put |
|
|
769 | put_failed # put |
|
|
770 | put_fetchable # put |
|
|
771 | put_successful # put |
|
|
772 | |
|
|
773 | sending_to_network # get |
|
|
774 | compatibility_mode # get |
|
|
775 | expected_hashes # get |
|
|
776 | expected_mime # get |
|
|
777 | expected_data_length # get |
|
|
778 | get_failed # get |
|
|
779 | data_found # get |
|
|
780 | enter_finite_cooldown # get |
|
|
781 | |
|
|
782 | In addition, an event (basically a fake message) of type C<request_changed> is generated |
|
|
783 | on every change, which will be called as C<< $cb->($fcp, $kv, $type) >>, where C<$type> |
|
|
784 | is the type of the original message triggering the change, |
|
|
785 | |
|
|
786 | To fill this cache with the global queue and keep it updated, |
|
|
787 | call C<watch_global> to subscribe to updates, followed by |
|
|
788 | C<list_persistent_requests_sync>. |
|
|
789 | |
|
|
790 | $fcp->watch_global_sync_; # do not wait |
|
|
791 | $fcp->list_persistent_requests; # wait |
|
|
792 | |
|
|
793 | To get a better idea of what is stored in the cache, here is an example of |
|
|
794 | what might be stored in C<< $fcp->{req}{"Frost-gpl.txt"} >>: |
|
|
