Three remaining issues surfaced with the RPATH setting - two minor, one trickier. Minor #1 - Itcl and Itk didn't have the RPATH flag set in their target definitions (fixed). Minor #2 - 3rd party binaries RPATHs don't match those produced by the main CMake build - using bin instead of lib (investigating). More significant is the behavior of CMake's RPATH_CHANGE - it is correctly setting the final path, but it is not clearing the build dir path. So far I've not found a way to make the available commands in CMake do the job, so I'm falling back on a solution similar to that necessary on Apple and using the chrpath utility. The code in this commit works if a system chrpath is present - we'll need to bundle a version in misc/tools to make sure we have the capabilities we need reliably. (chrpath is GPL, so we can't install it or use it as anything except a build tool - unfortunately I've not found a BSD/MIT licensed tool for this type of rpath work...)

Material object representation with multiple AVS sets for different types of material properties. There is a parent field within the object struct but there is currently no inheritance. There is also an update for the typein command.

We don't want this to accidentally activate if -lasan is no longer a requirement someday - BRL-CAD's code isn't ready for it yet. In particular, the LeakSanitizer trips up on the rt_free_rti/rt_clean tangle as well as _db_walk_subtree. The former may need elimination of the rt_uniresource global to properly clean up, and the latter is deep in the raytracing core and will have to be approached very carefully. For convenience, here are the backtraces: 889: Test command: build/bin/gqa "-P" "1" "-Ao" "-p" "ovlp_" "brlcad/src/gtools/tests/../../libged/tests/ged_tests.g" "ovlp" 889: Test timeout computed to be:

Oof. Writing down the details on this one, as I doubt I'll remember...
The start was turning on both the AddressSanitizer and Qt. When doing
so, most programs suddenly began reporting memory leaks. However, the
report was rather cryptic, being four entries similar to this one:
==1262202==ERROR: LeakSanitizer: detected memory leaks
Direct leak of 21 byte(s) in 1 object(s) allocated from:
#0 0x498087 in posix_memalign (build/src/libdm/tests/dm_test+0x498087)
#1 0x7f4e90e53675 in alloc brlcad/src/libbu/malloc.c:129:10
#2 0x7f4e90e53400 in bu_malloc brlcad/src/libbu/malloc.c:167:12
#3 0x7f4e90ee1c02 in bu_strdupm brlcad/src/libbu/str.c:165:17
#4 0x7f4e87dcd3e9 (<unknown module>)
#5 0x7f4e87dcdea5 (<unknown module>)
#6 0x7f4e9650eb89 (/lib64/ld-linux-x86-64.so.2+0x11b89)
I wasn't immediately sure if the unknown module error was related to the
plugin loading, and spent a lot of time trying to find a string memory
issue in dm_init.cpp. After that proved fruitless, other than to
confirm that the error disappeared if i removed the bu_dlclose-ing of
the handles saved at initialization, I began to look for ways to decode
the "unknown module" entries. That led to the following issue:
google/sanitizers#89 which describes the
problem ASan has with dynamic libraries. Comments indicated that it
would see real issues, but won't report which dynamic library they come
from (and there are no plans to fix this anytime soon... grr...). In
fairness, valgrind can see the error too but also has the same reporting
problem; it appears to be ubiquitous.
Fortunately, we have an alternative due to the way our plugin system and
test apps work - we can simply add and remove .so files to the directory
and see how the error reporting changes to zero in on which file(s) are
triggering the problem. Doing so quickly made apparent what should have
been obvious in retrospect - two of the errors each were coming from the
Qt and swrast plugins, which had been off in earlier testing.
Since there was no backtrace beyond the bu_strdupm call itself, and
there were two errors per file, the suspect was the bu_strdup calls
initializing the "char *" names for the fb structures. The C files use
static strings (which is why the non-Qt plugins didn't show the issue),
but C++ doesn't tolerate the type mismatch. The original hack
workaround was just to bu_strdup and create a (char *) string, but as
the leak detectors correctly note this also means there's no way to
clean up the allocated memory.
As far as I can tell there is no reason for these strings to be editable
(char *) strings - the dm container's equivalents are static. This
commit removes any logic assuming if_name is dynamic, and also removes
the bu_strdup hack from Qt and swrast.
