| 09:33.24 | andrei | brlcad, please say when you're arround |
| 09:39.28 | brlcad | andrei: that's the general idea, yes |
| 09:39.47 | brlcad | there is a manual page for the redblack API that might help |
| 09:39.53 | brlcad | brlman libredblack |
| 09:39.59 | andrei | Well I ve been reading the code for a while |
| 09:40.07 | brlcad | er, "brlman redblack" actually |
| 09:40.11 | andrei | and what I understood is that in the node structure |
| 09:40.15 | andrei | you actually store a list of |
| 09:40.51 | andrei | sec, let me find the exact name of the structure |
| 09:41.17 | andrei | bu_rb_package |
| 09:41.21 | andrei | that contains the generic data |
| 09:46.03 | brlcad | andrei: I believe that's the general idea though you're not supposed to know that directly ... that's a private structure member |
| 09:46.12 | *** join/#brlcad Stattrav (~Stattrav@unaffiliated/stattrav) | |
| 09:46.54 | brlcad | actually, I take that back -- that is the data container |
| 09:47.05 | brlcad | it's been a while since I've looked at that bit of api myself |
| 09:49.25 | brlcad | so you have to keep in mind that the API is a data-driven design, classic C, so you're seeing implementation details that must be declared mixed with API that you're expected to use |
| 09:50.02 | brlcad | I don't think you actually need to know about bu_rb_packages other than maybe for the purpose of creating a comparison func and even then I'm not positive you need to know |
| 09:50.25 | brlcad | bu_rb_insert() will populate a package for you, for example |
| 09:50.49 | andrei | hmm |
| 09:50.57 | brlcad | a good simple test would be to store strings into a rb tree |
| 09:51.20 | andrei | that was what I was trying to do |
| 09:51.31 | andrei | and use strlen(string) as a comp function |
| 09:52.01 | brlcad | you could insert something like "h", "e", "a", "l", "l", "o" .. then delete "a", then traverse all nodes and see if you can find h e l l o |

| 09:54.30 | andrei | regarding arbitrary inserts |
| 09:54.41 | andrei | I'm not entirely sure at what is the compare function used |
| 09:54.47 | andrei | as I see there is a pointer to a compare function |
| 09:55.17 | andrei | ah nevermind |
| 09:56.12 | Stattrav | brlcad: is there a list of requirements for the brlcad build on linux ? |
| 10:04.48 | brlcad | Stattrav: have you seen https://sourceforge.net/projects/brlcad/files/BRL-CAD%20for%20Virtual%20Machines/ ? |
| 10:05.05 | brlcad | that's a fully preconfigured checkout and install of brl-cad on linux ready to go |
| 10:05.20 | brlcad | you'll just need to download VirtualBox and have about 6GB of disk space available |
| 10:05.54 | brlcad | the doc/README.Linux might list requirements, but they are very very minimal |
| 10:06.05 | Stattrav | aah :) |
| 10:06.32 | Stattrav | I was building from SVN and the cmake failed and thus installed the necessary packages |
| 10:06.41 | Stattrav | I can add to them though |
| 10:07.10 | brlcad | cmake may fail for a huge range of issues including misconfigured cmake :) |
| 10:07.35 | brlcad | the actual requirements are something minimal like cmake, make, gcc/g++ |
| 10:08.06 | Stattrav | so bullet, freetype2, libxi-dev, libxft-dev |
| 10:08.10 | brlcad | plus some optional bits like x11 libs (dev and user), lex/yacc, and a few other assumptions |
| 10:08.14 | Stattrav | yeah |
| 10:11.30 | brlcad | andrei: have you read the section of include/bu.h on the redblack structures/functions? |
| 10:11.52 | andrei | yes |
| 10:11.53 | brlcad | that's probalby the best starting point |
| 10:11.59 | brlcad | cool |
| 10:12.02 | andrei | from what you told me |
| 10:12.08 | andrei | you want me to use the wrappers |
| 10:12.23 | andrei | rather than the primary functions |
| 10:13.35 | andrei | oh, actually not |
| 10:14.02 | andrei | I thought bu_rb_insert is a wrapper over |
| 10:14.04 | andrei | HIDDEN int |
| 10:14.05 | andrei | _rb_insert |
| 10:17.54 | andrei | just a second |
| 10:17.57 | andrei | I m trying to get something clear |
| 10:25.44 | andrei | <PROTECTED> |
| 10:25.45 | andrei | but |
| 10:27.18 | andrei | <PROTECTED> |
| 10:27.58 | andrei | what is the order parameter |
| 10:27.59 | andrei | role |
| 10:29.00 | andrei | I can't find the rb_order_func in order to see what it does |
| 10:29.18 | andrei | ah, nevermind, I found the macro |
| 10:31.35 | brlcad | you can ignore HIDDEN functions |
| 10:31.38 | brlcad | they're implementation detail |
| 10:31.41 | brlcad | HIDDEN is "static" |
| 10:32.17 | brlcad | when it doubt, just pass a zero ;) |
| 10:32.44 | andrei | the basic red black tree node has a key and a valu |
| 10:32.46 | andrei | e |
| 10:49.52 | andrei | The rb tree in bu.h isn't actually a binary tree of some order? |
| 11:04.50 | brlcad | andrei: I'm not sure I understand your question |
| 11:05.01 | brlcad | usually order would be the maximum number of children in a node |
| 11:05.24 | brlcad | but order might also be related to traversal ordering |
| 11:05.48 | andrei | exactly |
| 11:06.02 | andrei | no, now everything became clear |
| 11:06.12 | andrei | I had no idea what s with the "order" parameter |
| 11:06.28 | brlcad | if it's in the API, it's probably traversal ordering |
| 11:06.42 | brlcad | whether to traverse preorder, postorder, inorder |
| 11:07.39 | andrei | hold on, I ll upload a picture , maybe that will help you understand what I mean |
| 11:08.03 | andrei | http://i.imgur.com/eAXdl.png |
| 11:10.44 | brlcad | a see a tree ... and? :) |
| 11:10.51 | andrei | and the order represents |
| 11:10.56 | andrei | the number of the node |
| 11:11.21 | andrei | if I m not mistaken |
| 11:11.25 | brlcad | yes ... |
| 11:11.30 | andrei | order 0 in first node should be node 8 |
| 11:11.43 | andrei | and order 2 is 17 |
| 11:11.49 | brlcad | er ... |
| 11:12.17 | brlcad | that's not how I'd define order |
| 11:13.16 | brlcad | one (of many) possible definition of order is the maximum number of children for each node |
| 11:13.28 | brlcad | for that diagram, that'd be "order 4" |
| 11:13.36 | brlcad | and it applies to the whole tree |
| 11:13.48 | brlcad | as each node has potentially four children |
| 11:14.19 | brlcad | THAT SAID ... order in the API could simply refer to the order of _traversal_ |
| 11:16.15 | brlcad | if I walked that tree, do I get 1,6,8,11,13,... or do I get 13,8,1,6,11,... or 6,1,11,.. etc |
| 11:16.33 | brlcad | inorder, preorder, postorder, etc |
| 11:17.07 | andrei | well |
| 11:17.29 | brlcad | I'd bet rb_* api refers to traversal, not describing the tree |
| 11:17.41 | brlcad | need a more specific question at least |
| 11:18.15 | andrei | void |
| 11:18.17 | andrei | bu_rb_walk(struct bu_rb_tree *tree, int order, void (*visit) (/* ??? */), int trav_type) |
| 11:18.29 | andrei | the type of "walking " is clearly dictated by trav_type |
| 11:18.49 | andrei | and it s defined in bu.h as |
| 11:18.58 | andrei | preorder - 0 , inorder - 1 and post - 2 |
| 11:19.36 | andrei | my understanding is that this function walks the tree in the chosen mode |
| 11:19.53 | andrei | and applies a function to everynode |
| 11:21.23 | brlcad | so for that function, I'd agree |
| 11:22.11 | brlcad | iirc, many of the bu_rb_*() have an 'order' parameter and they don't all mean what it means to bu_rb_walk |
| 11:23.55 | brlcad | reading through redblack.3 I believe that order parameter refers to which comparison function to use |
| 11:24.28 | brlcad | it looks like you can store multiple "orders" per node and have a different comaprison function for each |
| 11:26.05 | brlcad | so basically it's a tree of lists and it's asking which list entry do you want |
| 11:26.27 | brlcad | most of the time there would only be 1 so it's probably either 0 or 1 depending on where the index starts |

| 14:31.34 | brlcad | andrei: so it's already different than it was when you first ran the VM |
| 14:32.28 | andrei | I think so, yes. |

| 14:33.43 | brlcad | andrei: so there's a brlcad-trunk-svn dir -- that's your svn checkout |
| 14:33.53 | brlcad | i.e., your source dir |
| 14:34.10 | brlcad | there should also be a brlcad-build dir (or similarly named) |
| 14:34.24 | brlcad | that's your build directory |
| 14:34.53 | andrei | there is a brlcad-build indeed |
| 14:34.58 | andrei | but it's empty |
| 14:35.29 | brlcad | if you cd to it, and run make, what happens? |
| 14:36.04 | andrei | make: *** No targets specified and no makefile found. Stop. |
| 14:36.21 | brlcad | okay, so apparently tom nuked it in the latest version |

| 14:36.36 | brlcad | in the build dir |
| 14:36.58 | andrei | I believe the directory is called brlcad-svn , I think it's the same thing tho |
| 14:37.07 | brlcad | okay, that |
| 14:37.27 | brlcad | he apparently renamed the dirs in the latest image |
| 14:37.58 | andrei | it's my fault anyway, I m too unsecure to realise even obvious matters |

| 15:33.45 | andrei | Yes |
| 15:33.52 | andrei | if you mean minor bugs |
| 15:34.02 | stas | was just curious |
| 15:34.09 | andrei | for example the first time I boot , I cannot change the bootloader option |
| 15:34.15 | andrei | it s like I have no stdin control |
| 15:34.31 | stas | thats grub2 actually |
| 15:35.14 | andrei | aside of that |

| 16:33.31 | brlcad | stas: that's usually a good idea |
| 16:36.59 | andrei | brlcad , I ve been reading the CMakeLists for a bit |
| 16:37.15 | andrei | is there where I should add my source? |
| 16:37.46 | brlcad | you put your .c file into the src/libbu source directory |
| 16:37.52 | Stattrav | brlcad: what in the benchmarks do you need to store ? just the summary or the entire run and frame info ? |
| 16:38.06 | andrei | I already have done that |
| 16:38.22 | brlcad | andrei: make sure you have a full build, then edit src/libbu/CMakeLists.txt to add your .c file to the build |
| 16:38.23 | Stattrav | and most importantly I've just submitted my latest benchmarks to benchmark@brlcad.org |
| 16:38.56 | brlcad | Stattrav: everything |
| 16:38.58 | andrei | I have a full build and I have added my file( which is called test_rb.c) in /src/libbu |
| 16:39.12 | andrei | and I'm stuck at adding it in Cmakelists.txt |
| 16:39.27 | brlcad | Stattrav: a benchmarks database should preserve the original log file (entirely, unmodified) as well as all useful extractable values |
| 16:39.31 | Stattrav | brlcad: and brlcad.org uses its own mail server ? IMAP |
| 16:39.50 | stas | please take a look at this page when you have a minute http://stas.github.com/resume.html, if there are questions, just ping me |
| 16:39.51 | stas | thanks |
| 16:40.55 | Stattrav | yeah I got that part of storing the entire log. but I was just wondering if I were write the regexes to extract the values what needs to be extracted. |
| 16:41.24 | brlcad | everything that's useful to extract (which is just about everything not constant) |

| 16:44.35 | brlcad | looks great, just make sure you include a link to it in your proposal write-up |
| 16:45.04 | stas | thanks, I'll do. anyway, I'll stay around |
| 16:45.40 | brlcad | great, might get to those questions beforehand then (just not today) |
| 16:48.31 | stas | deal |
| 16:57.50 | Stattrav | Oh, nice the benchmark shell script also checks for the --enable-runtime-debug and --enable-optimized |

| 17:16.12 | CIA-128 | BRL-CAD: Gah. We were getting away with checking a series of hard-coded subpaths for the |
| 17:16.12 | CIA-128 | BRL-CAD: data subdirectory in bu_brlcad_data. Have CMake tell us what the right value is |
| 17:16.12 | CIA-128 | BRL-CAD: via brlcad_config.h. Leave the hard-coded paths as a fall-back. |

| 17:22.29 | brlcad | Stattrav: what do you mean by "fixing" a db schema? you mean defining one? |
| 17:22.35 | Stattrav | yeah |
| 17:22.43 | Stattrav | defining one |
| 17:22.43 | andrei | for example my test code is called test_rbtree. can I use |
| 17:22.44 | brlcad | you'll want/need to define one for at least some basic machine characteristics |

| 17:23.08 | andrei | ah nevermind |
| 17:23.20 | andrei | I realised found the answer, thanks anyway |
| 17:23.24 | andrei | I found* |
| 17:23.37 | brlcad | andrei: glad to help ;) |
| 17:24.17 | andrei | I needed a CMake tutorial as I was completely lost in it :) |
| 17:24.35 | andrei | and it became clear after I read it |
| 17:24.46 | brlcad | Stattrav: so the entire point of the benchmark database is to characterize a given run against a database of existing runs, so basic hardware metrics will need to be tracked/extracted |
| 17:25.03 | Stattrav | yes. Machine characteristics, summary of the benchmark run, performance metric, some flags ? |
| 17:25.06 | brlcad | the problem is that those metrics are not well-defined because of the huge variety of hardware involved |
| 17:25.24 | Stattrav | version of brlcad being run |
| 17:26.40 | brlcad | sure, but that's trivial |
| 17:26.42 | Stattrav | You must already have an instance of MySQL or some SQL running at the moment to support drupal and mediawiki right. |
| 17:27.07 | brlcad | harder, I might want to know whether there is much/any difference between a quad core cpu and quad-cpu single core machines |
| 17:27.11 | brlcad | over time |
| 17:27.18 | Stattrav | ohh |
| 17:27.19 | brlcad | and that's not easily derived from the log files |
| 17:27.28 | brlcad | but it's there |
| 17:27.45 | Stattrav | that could be obtained from the cpuinfo on linux and windows and mac I should check it up |
| 17:27.46 | brlcad | at least for some logs |
| 17:28.30 | brlcad | the logs are what they are -- some have /proc/cpuinfo, some have sysctl output, some have uname -a, etc... |
| 17:28.45 | brlcad | depends on the OS, hardware, tools installed, etc |
| 17:28.56 | Stattrav | yeah I have seen uname -a |
| 17:29.01 | brlcad | when it's available, it's shoved into the log |
| 17:29.15 | brlcad | look at your log (the actual file, not just what was displayed) |
| 17:29.17 | Stattrav | Python has a crossplatform libs iirc |
| 17:29.41 | Stattrav | yeah |
| 17:29.47 | brlcad | we run on more platforms than python :) |

| 17:34.20 | Stattrav | sure |
| 17:34.54 | brlcad | so if selected, you'd probably spend a solid week developing a robust set of tables that capture everything |
| 17:35.29 | Stattrav | yup |
| 17:36.32 | Stattrav | give me 5-10 mins, I shall this schema for what I think I can extract so far. just for the heck of it |
| 17:36.45 | brlcad | a good patch submission could be a quick first-stab at that or some enhancement/fix to the benchmark tool |
| 17:36.45 | Stattrav | s/shall/shall write/ |
| 17:37.06 | brlcad | think about this in terms of users too, not just raw data |
| 17:37.32 | Stattrav | ohh, do you have some pending fix to benchmark tool ? |
| 17:38.27 | brlcad | there's a couple-todo's related to it, like making it output the CPPFLAGS/CFLAGS used to compile rt |
| 17:38.53 | brlcad | that's potentially an rt mod, but it'd get exposed through the bencmark tool |
| 17:39.33 | brlcad | another could be a C mod to our libbu basic utility library |
| 17:39.54 | brlcad | it often outputs (unknown) for the tool name during production compiles |
| 17:40.59 | Stattrav | ohh |
| 17:40.59 | brlcad | gsoc students, new project idea just added by one of the mentors: http://brlcad.org/wiki/Convert_BoT_to_Pipe |
| 17:41.04 | brlcad | just fyi |
| 17:55.11 | Stattrav | brlcad: which one in the basic utility ? |
| 17:58.45 | brlcad | try a release build, then re-run the benchmark -- your log file may have some information missing |
| 17:59.29 | Stattrav | ohh |
| 17:59.32 | Stattrav | let me check that |
| 17:59.45 | Stattrav | i have 7.20 on my machine as well |
| 17:59.53 | brlcad | the libbu routines in question are bu_which() and bu_whereis() along with the one that pulls up /proc/cpuinfo |
| 18:00.22 | brlcad | the issue is related to our modes of compilation and strictness |
| 18:00.39 | Stattrav | ohh |
| 18:00.47 | brlcad | if you compile in a strict compliance mode, you don't get some libc routines, so the implementation falls back to nothing (unknown) |
| 18:01.22 | brlcad | the fix would need to either figure out something more clever or find/define additional fallback methods |
| 18:02.03 | Stattrav | ohh |

| 18:19.12 | Stattrav | the schema that is |
| 18:22.51 | brlcad | mu gut inclination would be to keep the original logs as files on disk instead of in the db |
| 18:23.39 | brlcad | so a dev could do their own quick processing or scripting if needed using grep/awk/whatever instead of having to fire up an sql query |
| 18:23.40 | Stattrav | aah |
| 18:23.52 | brlcad | not a strong inclination, so welcome comments |
| 18:24.10 | Stattrav | but you wanted some kind of plots etc |
| 18:24.27 | Stattrav | replication ? |
| 18:24.32 | brlcad | sure, but then you will have extracted everythign from the logs into the db |
| 18:24.34 | Stattrav | as in store them on the disk as well as the db |
| 18:24.47 | Stattrav | oh yeah that is what i mean |
| 18:24.47 | brlcad | think of the file as the "paper trail" |
| 18:25.07 | brlcad | you could regenerate/repopulate the db with the files |
| 18:25.14 | Stattrav | yes |
| 18:25.37 | Stattrav | a population script could always be written |
| 18:26.06 | brlcad | there you have milestone #2 then ;) |
| 18:26.24 | Stattrav | aahaha |
| 18:27.22 | Stattrav | that was the first job I had when I was working, write the db population scripts for the load testing. They thought I'd learn the codebase and schema through that |
| 18:28.59 | brlcad | also, other comments on the schema -- you'll want to try and capture a characterization of the hardware/os/compiler/cadversion (probably four separate other tables) |
| 18:29.17 | Stattrav | oh yeah |
| 18:29.55 | Stattrav | and link these tables via id (foreign key) |
| 18:30.10 | brlcad | right |
| 18:31.49 | Stattrav | so grep over the codebase reveals that bu_which is used for just uname, sysctl, pwd, tclcadautopath, terminal and editors. That is it right |
| 18:32.48 | Stattrav | brlcad: btw do you want me to write a sample API for submission via the HTTP or via the mail ? |
| 18:33.36 | brlcad | an architecture diagram would be more helpful initially |
| 18:33.41 | Stattrav | sure |
| 18:34.06 | brlcad | can get to api details later |
| 18:35.01 | Stattrav | sure |
| 18:36.47 | *** join/#brlcad stas (~stas@188.24.46.106) | |
| 18:37.50 | Stattrav | Cant think of anyother modes of submission apart from HTTP API, via mail, ftp sync. Is there anything else that is commonly used that I am missing ? |
| 18:39.06 | brlcad | devs that manually drop a log (via scp/cp) into a queue dir |
| 18:39.20 | brlcad | http and mail should just drop into that queue dir too |

| 18:43.57 | Stattrav | brlcad: sure. tomorrow, I shall present you a diagram/UML for the same. Got to get some things done for my classes tomorrow. thank you btw |
| 18:43.58 | Akshat | <brlcad> you there |
| 18:44.08 | Stattrav | Akshat: he is always here. Just ask :) |
| 18:44.09 | brlcad | ~ask |
| 18:44.09 | ibot | Questions in the channel should be specific, informative, complete, concise, and on-topic. Don't ask if you can ask a question first. Don't ask if a person is there; just ask what you intended to ask them. Better questions more frequently yield better answers. We are all here voluntarily or against our will. |
| 18:44.40 | Akshat | ok |
| 18:44.44 | brlcad | Stattrav: it doesn't need to be uml (and is fine if it is) -- just need the notion |
| 18:44.50 | brlcad | like the cia.vc diagram I posted on the list |
| 18:44.54 | Akshat | i was interested in code reduction can i know which type of code will i get |
| 18:45.21 | brlcad | Akshat: you get the code you select |
| 18:45.36 | brlcad | we're not going to give you code and say "reduce this" |
| 18:45.50 | Stattrav | brlcad: it is easier for me to make one than anything else :) emacs |
| 18:45.52 | brlcad | you will figure out what to refactor, discuss, and proceed |
| 18:47.03 | Akshat | nice , i even doen't expect that :) |
| 18:48.32 | Akshat | <brlcad> i am new to chatzilla, and might be reacting inappropriately |
| 18:49.39 | brlcad | Akshat: no problem, there are plenty of people around to tell you if/when you're being annoying or doing something wrong ;) |
| 18:49.43 | brlcad | like that |
| 18:49.46 | brlcad | that's annoying |

| 19:07.00 | Akshat | its good |
| 19:07.35 | Akshat | so how are you working over it |
| 19:09.45 | ksuzee | Well, I've already registed on Mail Lists, as Sean advised me. Also, I'm dowloading the sources to start working out with them. And you? |
| 19:11.43 | Akshat | i have joined today,but they have not replied yet. so what is this "sources" , bunch of code. |
| 19:14.27 | Akshat | hello!!! |
| 19:14.33 | ksuzee | I mean the open code of the project |
| 19:15.19 | Akshat | is that interesting to you |
| 19:15.21 | Stattrav | Akshat: as brlcad points out, repeated "Hello"s with multiple question marks are annoying |
| 19:15.58 | Akshat | <stattrav> ok |
| 19:16.55 | ksuzee | "<Akshat> is that interesting to you" - is it for me? |
| 19:17.56 | Akshat | <ksuzee> yes , i just wanted to know , is working with that stuff a fun |
| 19:21.39 | ksuzee | yes, I think, it's quite interesting |
| 19:24.40 | Akshat | <ksuzee> can you give me link address of that sources, it would be very kind. |
| 19:25.29 | ksuzee | here's it http://sourceforge.net/projects/brlcad/files/BRL-CAD%20Source/7.20.4/ Everythins's for you) |
| 19:25.59 | Akshat | <ksuzee> thank you |
| 19:30.48 | brlcad | even easier, if you download VirtualBox, we've provided a virtual disk image this year with everything downloaded and preinstalled |

| 20:57.11 | Al_Da_Best | ``Erik: Hi, I have a few ideas for one of the scientific projects for GSOC, namely the non-vacuum gravity simulator. I was thinking about expanding on the basic falling block(well, object) by adding in a number of adjustable parameters. I was thinking along the lines of making the ground plane variable, so you could alter say, the coeff of restitution and the simulation would model the result |
| 20:57.12 | Al_Da_Best | of that. Also possibly allow for falling through different fluids and at different depths of fluids (so allowing for a rapid change in density etc). |

| 22:20.53 | CIA-128 | BRL-CAD: 03starseeker * r49756 10/brlcad/trunk/ (5 files in 2 dirs): We only want Debug and Release builds for BRL-CAD. Always want Debug flags, even when doing optimized release builds, unless explicitly turned off. Try and correct logic to reflect that - untested on multiconfig. |

| 23:20.08 | andrei | Thank you |
| 23:20.10 | brlcad | Al_Da_Best: that would be an awesome project -- you should try to familiarize yourself with the existing simulation code |
| 23:20.28 | andrei | C90 standards are messing up my logic a bit |
| 23:21.10 | Al_Da_Best | brlcad, I'm starting to do so, mainly just looking around the source to see where things fit together at the moment |
| 23:25.32 | brlcad | src/libged/simulate is where the main effort is that resulted in http://www.youtube.com/watch?v=SByoQQStH2s |
| 23:27.23 | brlcad | some work is still needed, though, as seen: http://www.youtube.com/watch?v=nrOtSd07rCY&feature=related |
| 23:28.18 | brlcad | ideally, someone working that area would familiarize and finish the pieces remaining, then move on to new features |
| 23:28.19 | Al_Da_Best | Cool. Yeah the second video clearly shows issues there |
| 23:28.34 | Al_Da_Best | Indeed. Get the basics down before complicating it |
| 23:38.12 | Al_Da_Best | Just a small error I've noticed on the Checklist page, the dates for draft/final application are in July instead of March/April (http://brlcad.org/wiki/Summer_of_Code/Checklist) |
| 23:39.02 | Al_Da_Best | Well, not so much an error so much as aimed at a different event (I think) |
| 23:39.11 | brlcad | yeah, that was for socis |
| 23:39.25 | andrei | brlcad |
| 23:39.31 | Al_Da_Best | Thought it might be |
| 23:39.41 | andrei | I managed to get the insert/delete functions tester working |
| 23:39.59 | andrei | however I have some small understanding issues regarding the way the "rb_walk" function works |
| 23:40.02 | CIA-128 | BRL-CAD: 03Sean 07http://brlcad.org * r3335 10/wiki/Summer_of_Code/Checklist: update dates for gsoc2012 |
| 23:42.19 | andrei | as it is written now , it will only walk through nodes containing data |
| 23:45.23 | andrei | the "visit" function can only be called with an void *data and a depth parameter? |
| 23:46.28 | andrei | as it's called by visit(rb_data(root, order), depth); or visit(<node>, depth); |
| 23:58.30 | brlcad | andrei: glad to hear it's mostly working, but I'd have to read the impl to know the answer to your question, don't recall off the top of my head |
