MSAN, ASAN, & TSAN

Testing Skia with memory, address, and thread santizers.

Downloading Clang Binaries (Googlers Only)

CLANGDIR="${HOME}/clang"
python infra/bots/assets/clang_linux/download.py -t $CLANGDIR

Building Clang from scratch

CLANGDIR="${HOME}/clang"

python tools/git-sync-deps
CC= CXX= infra/bots/assets/clang_linux/create.py -t "$CLANGDIR"

Configure and Compile Skia with MSAN

CLANGDIR="${HOME}/clang"
mkdir -p out/msan
cat > out/msan/args.gn <<- EOF
    cc = "${CLANGDIR}/bin/clang"
    cxx = "${CLANGDIR}/bin/clang++"
    extra_cflags = [ "-B${CLANGDIR}/bin" ]
    extra_ldflags = [ "-B${CLANGDIR}/bin", "-fuse-ld=lld", "-L${CLANGDIR}/msan" ]
    sanitize = "MSAN"
    skia_use_fontconfig = false
EOF
python tools/git-sync-deps
bin/gn gen out/msan
ninja -C out/msan

You may also need to install the following packages to run the MSAN binary

sudo apt-get install libc++dev libc++abi-dev

Configure and Compile Skia with ASAN

CLANGDIR="${HOME}/clang"
mkdir -p out/asan
cat > out/asan/args.gn <<- EOF
    cc = "${CLANGDIR}/bin/clang"
    cxx = "${CLANGDIR}/bin/clang++"
    sanitize = "ASAN"

python tools/git-sync-deps
bin/gn gen out/asan
ninja -C out/asan

Configure and Compile Skia with TSAN

CLANGDIR="${HOME}/clang"
mkdir -p out/tsan
cat > out/tsan/args.gn <<- EOF
    cc = "${CLANGDIR}/bin/clang"
    cxx = "${CLANGDIR}/bin/clang++"
    sanitize = "TSAN"
    is_debug = false
