How to test DRD ~~~~~~~~~~~~~~~ 1. Start with compiling DRD. 2. Check as follows that all global symbols in DRD have been wrapped by the DRD_() macro (output must be empty): ( cd drd && nm -A drd*.o|grep ' T '|grep -v ' T vgDrd_' ) 3. Check as follows that all global symbols in the preloaded shared library are redirected functions (output must contain one symbol that starts with a double underscore, something like __i686.get_pc_thunk.bx): ( cd drd && nm -A vgpreload*.o|grep ' T '|grep -v ' T _vg' ) 4. Verify that all files needed for the regression tests are included in drd/tests/Makefile.am: ( cd drd/tests; for f in *.vgtest *.exp*; do grep -q "$f" Makefile.am || echo $f; done ) 5. Verify that all files referenced in EXTRA_DIST in drd/tests/Makefile.am exist: ( cd drd/tests; for e in $(awk '/\\$/{n=$0; sub("\\\\$", "", n); if (line != "")\ { line = line " " n } else { line=n }} \ /[^\\]$/{if (line != ""){print line;line=""};print}' < Makefile.am \ | sed -n 's/^EXTRA_DIST *=//p' | sed 's/..noinst_SCRIPTS.//') do [ -e "$e" ] || echo "$e" done ) 6. Run the regression tests as follows: perl tests/vg_regtest drd DRD_VERIFY_CONFLICT_SET=1 perl tests/vg_regtest drd 7. Run the regression tests that were developed for Thread Sanitizer: ./vg-in-place --tool=drd --check-stack-var=yes drd/tests/tsan_unittest 2>&1|less 8. Test the slowdown for matinv for various matrix sizes via the script drd/scripts/run-matinv (must be about 25 for i == 1 and about 50 for i == 10 with n == 200). 9. Test whether DRD works with standard KDE applications and whether it does not print any false positives. Test this both with KDE3 and KDE4 on Linux: ./vg-in-place --tool=drd --read-var-info=yes kate ./vg-in-place --tool=drd --read-var-info=yes --check-stack-var=yes kate ./vg-in-place --tool=drd --read-var-info=yes --trace-children=yes knode ./vg-in-place --tool=drd --read-var-info=yes --check-stack-var=yes --trace-children=yes knode ./vg-in-place --tool=drd --read-var-info=yes --check-stack-var=yes /usr/bin/designer and on Darwin: ./vg-in-place --tool=drd --trace-fork-join=yes --show-confl-seg=no --gen-suppressions=all /Applications/Utilities/Terminal.app/Contents/MacOS/Terminal ./vg-in-place --tool=drd --trace-fork-join=yes --show-confl-seg=no --gen-suppressions=all /Applications/Safari.app/Contents/MacOS/Safari 10. Test whether DRD works with standard GNOME applications. Expect race reports triggered by ORBit_RootObject_duplicate() and after having closed the GNOME terminal window: ./vg-in-place --tool=drd --read-var-info=yes --trace-children=yes gnome-terminal 11. Rerun the GraphicsMagick test suite: 1. Recompile gcc via drd/scripts/download-and-build-gcc. 2. Replace the distro-provided libgomp.so* by the newly compiled versions: cp $HOME/gcc-.../lib/libgomp.so.1.0.0.0 /usr/lib cp $HOME/gcc-.../lib64/libgomp.so.1.0.0.0 /usr/lib64 rpm --verify libgomp43-32bit rpm --verify libgomp43 3. Build and install Valgrind in /usr: ./autogen.sh && ./configure --prefix=/usr CC=$HOME/gcc-4.4.0/bin/gcc \ && make -s && make -s install 4. Download the GraphicsMagick source code: cvs -d :pserver:anonymous@cvs.graphicsmagick.org:/GraphicsMagick login cvs -d :pserver:anonymous@cvs.graphicsmagick.org:/GraphicsMagick co GraphicsMagick cd GraphicsMagick ./configure export OMP_NUM_THREADS=4 make -j2 -s MEMCHECK="$HOME/software/valgrind/vg-in-place --tool=drd --check-stack-var=yes --read-var-info=yes --quiet" check 5. Expected result: 776 tests / 23 expected failures / 147m24s user time on a E8400 CPU @ 3 GHz. 12. Test DRD with Firefox. First build and install Firefox 3: drd/scripts/download-and-build-firefox Now run the following command: LD_LIBRARY_PATH=$HOME/software/mozilla-build/dist/lib: ./vg-in-place --tool=drd --check-stack-var=yes --trace-children=yes --show-confl-seg=no $HOME/software/mozilla-build/dist/bin/firefox-bin 13. Verify that the XML output matches the DRD XML output XSD. drd/tests/verify-xml-output
