# 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 ./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

```

```
|
|
|
|
```
|
|
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
|
|
```
