| 04:47.28 | BulletCatcher | I am able to sidestep heartnet's segfault by not dereferencing the null pointer. |
| 04:47.33 | BulletCatcher | On the test map RenderNodeGStateList::sort() never gets a list size greater than 1, so there is no benefit to sorting it anyway. |
| 04:47.37 | BulletCatcher | The source of the null pointer may be in OpaqueRenderNode::getPosition(), but I'm not really sure. |
| 04:50.05 | BulletCatcher | I set a breakpoint at it, and that is indeed where it comes from. |
| 04:50.36 | BulletCatcher | I don't know what the proper fix is, though. |

| 06:23.03 | BulletCatcher | heartnet: I have found what causes the crash on your map, but I am not sure how to fix it. |
| 06:24.07 | heartnet | Is that the specific issue on my map? |
| 06:24.44 | BulletCatcher | It is a client bug that your map triggers. |
| 06:26.39 | BulletCatcher | There won't be a fix before 2.4.2, so it may be easiest to just not use the OO flag on your map. |
| 06:26.55 | heartnet | Ah I forgot I confirmed it on the map only with a treen and OO flags too. So I think the mesh object is the matter. |
| 06:27.21 | heartnet | I will not put any OO flags on my map. |
| 06:28.07 | heartnet | I also confirmed it on the following simple map. |
| 06:28.09 | heartnet | http://www.bzflag.jp/public/segfault.bzw |
| 06:28.39 | JeffM | even if there is a fix in 2.4.2 someone with an old client would crash |
| 06:28.49 | BulletCatcher | I used that map for my own testing. Thanks for narrowing the problem. |
| 06:29.05 | JeffM | the question is how does the node's position get null |
| 06:29.09 | JeffM | that would be super bad |
| 06:29.18 | heartnet | np. Is this bug so critical? |
| 06:29.44 | JeffM | what object does the node belong to? |
| 06:29.47 | BulletCatcher | JeffM: Read up. I think OpaqueRenderNode::getPosition() is the source of the null pointer. |
| 06:30.14 | JeffM | BulletCatcher, sure but that gets it's data from someting that set's the position |
| 06:30.24 | JeffM | render nodes are attached to scene nodes |
| 06:30.29 | BulletCatcher | No, it always returns NULL. |
| 06:30.31 | JeffM | and those nodes should have a postion |
| 06:30.35 | JeffM | really? |
| 06:30.40 | JeffM | that's stupid |
| 06:31.06 | JeffM | is it only the orderdList node that has the issue? |
| 06:31.53 | BulletCatcher | So far, the only place it seems to be a problem in RenderNodeGStateList::sort(). |
| 06:32.11 | JeffM | yes and that sorts based on position |
| 06:32.14 | JeffM | so it should have one |
| 06:32.24 | JeffM | we should not be adding nodes that don't have positions |
| 06:32.32 | *** join/#bzflag Djpenguin (~David@c-98-207-67-102.hsd1.ca.comcast.net) |
| 06:32.32 | JeffM | since we only draw things that have a place on the map |
| 06:34.44 | JeffM | do you know what object creates this render node that crashes? |
| 06:35.43 | BulletCatcher | No, but I should be able to isolate it. |
| 06:35.59 | JeffM | the position should be gotten from the object |
| 06:36.00 | BulletCatcher | The tree on the map is made up of several objects in a group. |
| 06:37.47 | JeffM | hmmm opaque objects are not sorted so that's why it's null |
| 06:38.09 | JeffM | so yeah we'd have to know who is sorting the objects and not making them as AlphaGroupRenderNode |
| 06:46.30 | JeffM | what line calls the sort that crashes? |
| 06:48.20 | BulletCatcher | http://pastebin.com/YVGJpxh1 has the backtrace |
| 06:50.52 | JeffM | do you have depth buffer on or off? |
| 06:52.04 | JeffM | or put a breakpoint on SceneRenderer.cxx:485 and step into scene->isOrdered() |
| 06:52.11 | BulletCatcher | Display Settings shows Depth Complexity off. Is that it? |
| 06:52.21 | JeffM | and tell me if it goes into the bsp or zscene |
| 06:52.50 | JeffM | cus for zbuffered it should not hit that sort section |
| 06:52.59 | JeffM | cus isOrdered will be false |

| 06:54.08 | BulletCatcher | I have the map down to a single (very complex) mesh object. |
| 06:54.15 | *** join/#bzflag Marzipan (~Marzipan@bzflag/player/Marzipan) |
| 06:54.47 | JeffM | yeah it probalby just needs a mesh with alpha |
| 06:55.13 | JeffM | I think I know what's going on, I just need to know what scene type you have, z or bsp |
| 06:55.23 | BulletCatcher | How can I tell? |
| 06:55.30 | JeffM | put a breakpoint where i said |
| 06:55.42 | JeffM | step into scene->isOrdered() |
| 06:55.48 | JeffM | and tell me what class it goes into |
| 06:55.51 | JeffM | it's a virtual function |
| 06:57.40 | BulletCatcher | Breakpoint hits at ZSceneDatabase::isOrdered(). |
| 06:57.52 | JeffM | and that should return false right? |
| 06:58.06 | BulletCatcher | yes |
| 06:58.12 | JeffM | setting inOrder to false |
| 06:58.20 | JeffM | ok |
| 06:58.35 | JeffM | then it's not what I think |
| 06:58.42 | JeffM | I wonder who fills out the orderdList |
| 06:59.34 | JeffM | put a breakpoint at line 356 in scenerenderer.h |
| 06:59.41 | JeffM | and see who's calling that |
| 07:00.30 | JeffM | someone is asking for sorting but has not provided a node that has alpha support and therfore does not support sorting |
| 07:01.50 | BulletCatcher | SceneRenderer::addRenderNode() is called by MeshSceneNode::addRenderNodes(). |
| 07:02.52 | BulletCatcher | Oh, but inOrder is false there. |
| 07:03.21 | JeffM | yeah it'll be false |
| 07:03.29 | JeffM | it sorts cus gstate wants ordering |
| 07:03.43 | JeffM | and that's usualy cus someone wants alpha |
| 07:04.00 | JeffM | mail me the map and I can debug it tomorow |
| 07:04.07 | JeffM | it's going to be in the nodes created in the LOD of the mesh |
| 07:04.12 | JeffM | probably due to the drawinfo |
| 07:04.18 | BulletCatcher | You want the breakpoint on exactly line 356. |
| 07:05.06 | JeffM | no it's going to happen a lot sooner |
| 07:06.49 | JeffM | probably in parseDrawSet |
| 07:07.00 | BulletCatcher | With the breakpoint at line 356, the backtrace says that EighthDimShellNode::addRenderNodes() calls SceneRenderer::addRenderNode(). |
| 07:07.40 | JeffM | yeah that's the OO nodes |
| 07:08.11 | JeffM | something is getting the sorting wrong with OO and drawinfos |
| 07:08.31 | JeffM | they arn't used often so that's probably why we have never seen it before |
| 07:10.43 | JeffM | the fix is going to be in figuring out how the missmatch between the node type and gstate happened |
| 07:12.19 | JeffM | I don't think it's a new bug, I'd just get it reported on SF |
| 07:15.48 | BulletCatcher | heartnet: Is it okay for me to include the essential part of the segfault.bzw file in a SourceForge bug report? That will make it public, permanently. |
| 07:21.07 | JeffM | he took that tree from loumans map that was released with an open source license |
| 07:21.14 | JeffM | it may be tied to LOD as well |
| 07:21.49 | heartnet | It's ok. |
| 07:21.57 | BulletCatcher | thanks |
| 07:22.02 | heartnet | np |
| 07:22.20 | JeffM | bet you could dupe it with a mesh that was just 2 quads in draw info |
