привет!

занимаюсь тестированием 3rd parties модулей.
один из вариантов тестирования - штатные тесты
https://github.com/nginx/nginx-tests

хотелось бы в том числе запускать их с ASAN.

но на nginx без модулей сейчас получается вот так (половина тестов
разваливается)

скажите, у вас есть практика запуска с asan ?


воспроизвести ошибку выше можно примерно так (для CentOS 7)


export NGINX_VERSION: 1.19.10

yum install -q -y epel-release
yum install -q -y centos-release-scl-rh
yum install -q -y devtoolset-9-toolchain devtoolset-9-libasan-devel
yum install -q -y which wget make gcc git openssl-devel
yum install -q -y "perl(Test::More)" 'perl(IO::Socket::SSL)'
'perl(Net::SSLeay)' 'perl(Protocol::WebSocket)' 'perl(IO::Compress::Gzip)'
'perl(JSON::PP)'
groupadd -r nginx
useradd -r -g nginx -d /var/cache/nginx nginx
usermod -o -u 0 nginx
groupmod -o -g 0 nginx
