285 | Basically, heres what this should do: | |
286 | 1) Determine correct packet handler for this packet | |
287 | 2) Mark the packet handled (so it can be dequeued in purge_queue()) | |
288 | 3) Send the packet to the packet handler | |
289 | 4) Go to next packet in the queue and start over | |
290 | 5) When done, run purge_queue() to purge handled commands | |
291 | ||
292 | Note that any unhandlable packets should probably be left in the | |
293 | queue. This is the best way to prevent data loss. This means | |
294 | that a single packet may get looked at by this function multiple | |
295 | times. This is more good than bad! This behavior may change. | |

692 | * The Rate Limiting System, An Abridged Guide to Nonsense. | |
693 | * | |
694 | * OSCAR defines several 'rate classes'. Each class has seperate | |
695 | * rate limiting properties (limit level, alert level, disconnect | |
696 | * level, etc), and a set of SNAC family/type pairs associated with | |
697 | * it. The rate classes, their limiting properties, and the definitions | |
698 | * of which SNACs are belong to which class, are defined in the | |
699 | * Rate Response packet at login to each host. | |
700 | * | |
701 | * Logically, all rate offenses within one class count against further | |
702 | * offenses for other SNACs in the same class (ie, sending messages | |
703 | * too fast will limit the number of user info requests you can send, | |
704 | * since those two SNACs are in the same rate class). | |
705 | * | |
706 | * Since the rate classes are defined dynamically at login, the values | |
707 | * below may change. But they seem to be fairly constant. | |
708 | * | |
709 | * Currently, BOS defines five rate classes, with the commonly used | |
710 | * members as follows... | |
711 | * | |
712 | * Rate class 0x0001: | |
713 | * - Everything thats not in any of the other classes | |
714 | * | |
715 | * Rate class 0x0002: | |
716 | * - Buddy list add/remove | |
717 | * - Permit list add/remove | |
718 | * - Deny list add/remove | |
719 | * | |
720 | * Rate class 0x0003: | |
721 | * - User information requests | |
722 | * - Outgoing ICBMs | |
723 | * | |
724 | * Rate class 0x0004: | |
725 | * - A few unknowns: 2/9, 2/b, and f/2 | |
726 | * | |
727 | * Rate class 0x0005: | |
728 | * - Chat room create | |
729 | * - Outgoing chat ICBMs | |
730 | * | |
731 | * The only other thing of note is that class 5 (chat) has slightly looser | |
732 | * limiting properties than class 3 (normal messages). But thats just a | |
733 | * small bit of trivia for you. | |
734 | * | |
735 | * The last thing that needs to be learned about the rate limiting | |
736 | * system is how the actual numbers relate to the passing of time. This | |
737 | * seems to be a big mystery. | |
