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. Make sure you have installed required packages (clang, lld). It may be required to specify non-standard lld binary using LINKER_NAME option (e.g. -D LINKER_NAME=lld-8).

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

Copy binary to your server

scp ./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' ./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 CXX=clang++ cmake -D SANITIZE=memory ..
ninja
