00:07.07 Notify 03BRL-CAD:starseeker * 60464 brlcad/trunk/include/rt/search.h: Add warning to check for unexpectedly empty paths in user code to avoid accidental triggering of the tops population.
00:08.44 brlcad starseeker: er, why mysteriously invalid directory pointers?
00:11.21 Notify 03BRL-CAD:starseeker * 60465 brlcad/trunk/include/rt/search.h: Need to investigate the weird side effects a bit more...

00:44.34 Notify 03BRL-CAD:starseeker * 60466 brlcad/trunk/src/gtools/CMakeLists.txt: Start working on a new diff tool, based on the test example for db_diff. Doesn't do the mged script generation of g_diff, but it has a few other nifty features. It supports a -v option that takes 0 (no output, return code only), 1 (less verbose) and 2 (more verbose) as options to control how much information is reported. It accepts -a, -c, -u and
00:44.36 Notify -r options to enable reporting for added, changed, unchanged, and removed objects respectively (if none are supplied, the default is report all changes.) In addition, although it is not yet tested extensively, there is a -F option which lets the user supply a search-command-style filter string to filter results. Say, for example, you only want your diff output to report objects of type tgc. On a bash command prompt,
00:44.38 Notify that search would look like gdiff2 -F "-type tgc" file1.g file2.g and would report only items that were tgc primitives at some stage of the diffing process. I.e., an added tgc in file2.g would be reported, as would a primitive named s.1 that was changed from a tgc in file1.g to an ell in file2.g. This should provide a way to trim potentially large diff results down to what is of current interest to a user.
00:45.34 starseeker brlcad: the "cleanup" db_dirdelete calls at search.c:2276 were wiping out pointers I needed.

00:46.17 brlcad starseeker: ah
00:46.19 starseeker I may be doing something incorrect when cleaning up there
00:46.29 brlcad hence the follow-up comment
00:46.34 starseeker right
00:46.46 brlcad neat, new differ
00:46.59 starseeker too deep to get into tonight (I'm late already) but I was so close to a "searchified" diff I had to push through
00:48.16 starseeker had wild idea this afternoon, had to try it out
00:59.17 brlcad cool

02:21.34 Notify 03BRL-CAD:brlcad * 60467 brlcad/trunk/src/libbu/affinity.c: implement hooks that let a thread migrate around in local proximity, hopefully still on the same CPU. assumes multicore architecture is likely and that given core counts reflect a probable configuration. not ideal, but exploring the idea.
