How to use Address Sanitizer

Note: We use Address Sanitizer to run functional tests for every commit automatically.

mkdir build_asan && cd build_asan

Note: using clang instead of gcc is strongly recommended.

CC=clang CXX=clang++ cmake -D SANITIZE=address ..
ninja

Copy binary to your server

scp ./dbms/programs/clickhouse yourserver:~/clickhouse-asan

Start ClickHouse and run tests

sudo -u clickhouse ./clickhouse-asan server --config /etc/clickhouse-server/config.xml

How to use Thread Sanitizer

mkdir build_tsan && cd build_tsan
CC=clang CXX=clang++ cmake -D SANITIZE=thread ..
ninja

Start ClickHouse and run tests

sudo -u clickhouse TSAN_OPTIONS='halt_on_error=1,suppressions=../dbms/tests/tsan_suppressions.txt' ./clickhouse-tsan server --config /etc/clickhouse-server/config.xml

How to use Undefined Behaviour Sanitizer

mkdir build_ubsan && cd build_ubsan

Note: clang is mandatory, because gcc (in version 8) has false positives due to devirtualization and it has less amount of checks.

CC=clang CXX=clang++ cmake -D SANITIZE=undefined ..
ninja

Start ClickHouse and run tests

sudo -u clickhouse UBSAN_OPTIONS='print_stacktrace=1' ./clickhouse-ubsan server --config /etc/clickhouse-server/config.xml

How to use Memory Sanitizer

CC=clang-8 CXX=clang++-8 cmake -D ENABLE_HDFS=0 -D ENABLE_CAPNP=0 -D ENABLE_RDKAFKA=0 -D ENABLE_ICU=0 -D ENABLE_POCO_MONGODB=0 -D ENABLE_POCO_NETSSL=0 -D ENABLE_POCO_ODBC=0 -D ENABLE_ODBC=0 -D ENABLE_MYSQL=0 -D ENABLE_EMBEDDED_COMPILER=0 -D USE_INTERNAL_CAPNP_LIBRARY=0 -D USE_INTERNAL_SSL_LIBRARY=0 -D USE_SIMDJSON=0 -DENABLE_READLINE=0 -D SANITIZE=memory ..
