14 | /* |

15 | * In OSCAR, every connection has a set of SNAC groups associated |
---|
16 | * with it. These are the groups that you can send over this connection |
---|
17 | * without being guarenteed a "Not supported" SNAC error. |
---|
18 | * |
---|
19 | * The grand theory of things says that these associations transcend |
---|
20 | * what libfaim calls "connection types" (conn->type). You can probably |
---|
21 | * see the elegance here, but since I want to revel in it for a bit, you |
---|
22 | * get to hear it all spelled out. |
---|
23 | * |
---|
24 | * So let us say that you have your core BOS connection running. One |
---|
25 | * of your modules has just given you a SNAC of the group 0x0004 to send |
---|
26 | * you. Maybe an IM destined for some twit in Greenland. So you start |
---|
27 | * at the top of your connection list, looking for a connection that |
---|
28 | * claims to support group 0x0004. You find one. Why, that neat BOS |
---|
29 | * connection of yours can do that. So you send it on its way. |
---|
30 | * |
---|
31 | * Now, say, that fellow from Greenland has friends and they all want to |
---|
32 | * meet up with you in a lame chat room. This has landed you a SNAC |
---|
33 | * in the family 0x000e and you have to admit you're a bit lost. You've |
---|
34 | * searched your connection list for someone who wants to make your life |
---|
35 | * easy and deliver this SNAC for you, but there isn't one there. |
---|
36 | * |
---|
37 | * Here comes the good bit. Without even letting anyone know, particularly |
---|
38 | * the module that decided to send this SNAC, and definitly not that twit |
---|
39 | * in Greenland, you send out a service request. In this request, you have |
---|
40 | * marked the need for a connection supporting group 0x000e. A few seconds |
---|
41 | * later, you receive a service redirect with an IP address and a cookie in |
---|
42 | * it. Great, you say. Now I have something to do. Off you go, making |
---|
43 | * that connection. One of the first things you get from this new server |
---|
44 | * is a message saying that indeed it does support the group you were looking |
---|
45 | * for. So you continue and send rate confirmation and all that. |
---|
46 | * |
---|
47 | * Then you remember you had that SNAC to send, and now you have a means to |
---|
48 | * do it, and you do, and everyone is happy. Except the Greenlander, who is |
---|
49 | * still stuck in the bitter cold. |
---|
50 | * |
---|
51 | * Oh, and this is useful for building the Migration SNACs, too. In the |
---|
52 | * future, this may help convince me to implement rate limit mitigation |
---|
53 | * for real. We'll see. |
---|
54 | * |
---|
55 | * Just to make me look better, I'll say that I've known about this great |
---|
56 | * scheme for quite some time now. But I still haven't convinced myself |
---|
57 | * to make libfaim work that way. It would take a fair amount of effort, |
---|
58 | * and probably some client API changes as well. (Whenever I don't want |
---|
59 | * to do something, I just say it would change the client API. Then I |
---|
60 | * instantly have a couple of supporters of not doing it.) |
---|
61 | * |
---|
62 | * Generally, addgroup is only called by the internal handling of the |
---|
63 | * server ready SNAC. So if you want to do something before that, you'll |
---|
64 | * have to be more creative. That is done rather early, though, so I don't |
---|
65 | * think you have to worry about it. Unless you're me. I care deeply |
---|
66 | * about such inane things. |
