| 15:54:47 | lheuer | Did anybody created a DoS attack via mergeMap yet? |
| 15:56:13 | larsbot | don't know of anyone who allows outsiders to submit TM fragments |
| 15:56:17 | larsbot | so that makes it hard |
| 15:57:30 | larsbot | to execute the attack, I mean |
| 16:00:58 | lheuer | Jep. The user has to execute the initial XTM parsing process but then it is possible to either create an endless loop or to serve the topic map that should be merged very, very, very slow so that the application blocks. |
| 16:01:23 | arnarl | heh, sending in a document with a single topic that contains all the identifiers in the map :-) |
| 16:01:45 | arnarl | like watching a galaxy being sucked into a black hole |
| 16:01:54 | lheuer | :)) |
| 16:12:12 | lheuer | The possibility to unmerge topic maps will be become more important, once Topic Maps has left its micro cosmos. |
| 16:16:01 | arnarl | source-locators :-) |
| 16:16:06 | arnarl | that and transactions |
| 16:20:24 | larsbot | transactions help against the blocking problem |
| 16:20:50 | larsbot | but the endless loop you can create if you make it point back to some kind of service that keeps providing new URLs for every iteration |
| 16:22:23 | arnarl | oh, I didn't think about that |
| 16:22:42 | arnarl | fetching resources like that is a bit nasty. |
| 16:22:46 | larsbot | yes |
| 16:23:10 | lheuer | Wouldn't DoS attacks beeing a good argument to remove the mergeMap element from an *interchange* syntax? |
| 16:23:25 | larsbot | feel free to try :-) |
| 16:23:38 | arnarl | We didn't even bother to implement it :-) |
| 16:23:51 | larsbot | gra and I have tried arguing this for a long time, and got nowhere |
| 16:24:07 | arnarl | http://www.garshol.priv.no/blog/28.html <-- wow :-) |
| 16:24:19 | larsbot | in any case, I think probably people would reply that there's no reason why you can't disable mergemap in certain situations |
| 16:24:22 | arnarl | and a waiting list :-) |
| 16:24:23 | larsbot | and I guess they would be right |
| 16:24:31 | larsbot | arnarl: :-) |
| 16:24:59 | arnarl | the problem with all such features is that even if you do not support them you still need to account for them. |
| 16:25:12 | arnarl | makes the whole infrastructure more complex |
| 16:25:27 | arnarl | and complexity we do not need more of with Topic Maps. |
| 16:25:45 | lheuer | I've a flag to indicate if the mergeMap element should be ignored or not. But don't offer mergeMap would be the easiest solution |
| 16:26:53 | arnarl | I like the comparison with US population numbers, but it is even better because a sizable portion of the conference is in Norwegian. |
| 16:27:06 | arnarl | not exactly a world language compared to english. |
| 16:27:07 | larsbot | * larsbot dreams of TM conferences in China :-) |
| 16:27:35 | arnarl | just don't point out the freedoms TM afford you. :-/ |
| 16:27:37 | larsbot | complexity: I agree; things would be much easier without it |
| 16:27:43 | larsbot | freedoms: LOL |
| 16:27:59 | larsbot | but mergemap is something people really use |
| 16:28:04 | larsbot | so cutting it entirely is a bit harsh |
| 16:28:23 | larsbot | kal's proposal to have a separate TM packaging syntax has a lot of merit |
| 16:28:34 | larsbot | the only real problem is that it's a bit late in the day for that |
| 16:30:46 | arnarl | aren't you doing XTM 2.0 now? |
| 16:33:11 | larsbot | yes, that's where we might cut it |
| 16:48:51 | arnarl | bye bye, have a nice weekend everybody! :-) |
