IRC log for #brlcad on 20130418

01:54.10 Notify 03BRL-CAD:starseeker * 55178 (brlcad/trunk/misc/CMake/FindX11.cmake brlcad/trunk/src/other/incrTcl/itk/CMake/FindX11.cmake and 4 others): Try to tighten up the reporting when we have mixed paths - 'MATCHES' appears to be too loose. For some reason on Linux Mint libXpm is in /usr/lib rather than /usr/lib/x86_64-linux-gnu - that's fine, but the path difference triggers the reporting notice since it looks similar to
01:54.12 Notify cases on Mac OSX that are trouble - try not to say more than we need to. While we're at it, sync the src/other copies.

Go with DBL_MIN to get as close as possible to the original (working) exact comparisions without triggering compiler warnings.

17:37.09 starseek1r brlcad: do you think this would be a good reference for the SSI project? http://web.mit.edu/hyperbook/Patrikalakis-Maekawa-Cho/node56.html

18:16.23 brlcad starseeker: you have a stack trace on that seg fault? (55180)
18:20.27 brlcad or something I can try to reproduce it
18:20.37 brlcad don't doubt it, but might try for an additional fix
18:20.39 brlcad something with sensitivity under epsilon might be a portability problem (non IEEE 754 compilation)
18:21.10 brlcad the kind that bites hard years later
18:27.49 vladbogo hello
18:28.25 vladbogo i am trying to make a non graphical debug DM
18:28.41 vladbogo and i ran in quite a few problems
18:29.08 vladbogo i think i am missing something
18:30.52 vladbogo i see that mged_attach attaches a new DM but I don't understand why it's the background color initialized even though the DM can be non-graphical
18:31.10 vladbogo any idea?
18:38.33 brlcad what do you mean it attaches it?
18:38.58 brlcad it's not entirely surprising that assumptions of it being a graphical DM might be pervasive
18:39.14 brlcad setting a background color is necessarily a problem with, or is it?
18:39.47 brlcad I'd think even a debug DM would need to keep track of some state (like color) in order to correctly report settings
18:40.27 vladbogo you're right
19:04.03 starseeker brlcad: um. Don't have a stack trace handy, but easy to reproduce - just revert that change and then try shaded display of the 3dm test geometry example in regress/nurbs/
19:04.35 starseeker (or any other handy NURBS model, for that matter - didn't seem to matter which one we tried)
19:05.31 starseeker tar -xvjf regress/nurbs brep-3dm.tar.bz2 && 3dm -r -o brep.g brep.3dm
19:05.53 starseeker shaded viewing in mged or archer
19:06.03 starseeker will trigger the issue (at least here)
19:22.24 brlcad okay, thanks
19:22.28 brlcad see what I can find out
19:22.57 vladbogo hi again
19:23.19 vladbogo i think i managed to get the debug dm working
19:24.31 vladbogo but i want to ask you if it should print messages in a log file or is it ok to print to stdout?
19:29.03 Notify 03BRL-CAD:carlmoore * 55181 brlcad/trunk/src/util/cv.c: shift in_cookie , out_cookie to later (after file issues are checked out), and use argc == 5 because argc >5 was already elminated by earlier code
19:41.57 Notify 03BRL-CAD:carlmoore * 55182 brlcad/trunk/src/util/cv.c: insert 2 else's because if I get the 'huc' or 'nuc' strings, I know the strlen must be 3 so I don't need to test for strlen >4 || strlen <1
20:01.57 brlcad vladbogo: either is fine
20:02.09 vladbogo thanks
20:02.30 vladbogo i will probably submit the patch tomorrow
20:02.44 brlcad excellent!
20:02.49 brlcad ahead of the curve already ;)
20:02.55 vladbogo :)
20:02.57 brlcad make sure you read HACKING and match our style
20:03.02 brlcad that's the single biggest mistake
20:03.31 brlcad our style is probably a little different than you're used to and we're very strict about it needing to conform
20:03.35 vladbogo that's what i wanted to do because right now it's a little bit messy
20:03.38 brlcad indentation in particular
20:03.52 brlcad I definitely don't like messy :)
20:03.57 brlcad keep that to yourself :D
20:04.16 brlcad there are scripts in the sh directory that might help you
20:04.29 vladbogo well not quite messy but i used tabs instead of spaces and other similar things
20:04.38 brlcad sh/indent.sh and sh/ws.sh for example (along with template/header/footer)
20:04.53 brlcad we use both tabs AND spaces
20:05.09 brlcad it's a compressed fixed format
20:05.24 brlcad tabstops at 8, but indents are at 4
20:05.45 brlcad so it's 4spc, then 1 tab, then 1tab+4spcs, then 2tabs, and so on as you indent
20:05.46 vladbogo thanks
20:06.21 vladbogo i will take care
20:06.24 brlcad yw, thanks for your efforts too
20:07.24 vladbogo it was interesting working and i came to a more clear idea about the projects
20:08.14 vladbogo i was thinking about starting to make my application and post it as soon as possible in order to get a feedback
20:09.09 vladbogo is this ok or should I stick more on the code and make the application later?
