Las pruebas sin estado ejecutan consultas sin datos de prueba precargados: a menudo crean pequeños conjuntos de datos sintéticos sobre la marcha, dentro de la prueba misma. Las pruebas estatales requieren datos de prueba precargados de Yandex.Métrica y no está disponible para el público en general. Tendemos a usar sólo `stateless` pruebas y evitar la adición de nuevos `stateful` prueba. - -Cada prueba puede ser de dos tipos: `.sql` y `.sh`. `.sql` test es el script SQL simple que se canaliza a `clickhouse-client --multiquery --testmode`. `.sh` test es un script que se ejecuta por sí mismo. - -Para ejecutar todas las pruebas, use `clickhouse-test` herramienta. Mira `--help` para la lista de posibles opciones. Simplemente puede ejecutar todas las pruebas o ejecutar un subconjunto de pruebas filtradas por subcadena en el nombre de la prueba: `./clickhouse-test substring`. - -La forma más sencilla de invocar pruebas funcionales es copiar `clickhouse-client` a `/usr/bin/`, ejecutar `clickhouse-server` y luego ejecutar `./clickhouse-test` de su propio directorio. - -Para agregar una nueva prueba, cree un `.sql` o `.sh` archivo en `queries/0_stateless` directorio, compruébelo manualmente y luego genere `.reference` archivo de la siguiente manera: `clickhouse-client -n --testmode < 00000_test.sql > 00000_test.reference` o `./00000_test.sh > ./00000_test.reference`. - -Las pruebas deben usar (crear, soltar, etc.) solo tablas en `test` base de datos que se supone que se crea de antemano; también las pruebas pueden usar tablas temporales. - -Si desea utilizar consultas distribuidas en pruebas funcionales, puede aprovechar `remote` función de la tabla con `127.0.0.{1..2}` direcciones para que el servidor se consulte; o puede usar clústeres de prueba predefinidos en el archivo de configuración del servidor como `test_shard_localhost`. - -Algunas pruebas están marcadas con `zookeeper`, `shard` o `long` en sus nombres. -`zookeeper` es para pruebas que están usando ZooKeeper. `shard` es para pruebas que -requiere servidor para escuchar `127.0.0.*`; `distributed` o `global` tienen el mismo -significado. `long` es para pruebas que duran un poco más de un segundo. Usted puede -deshabilitar estos grupos de pruebas utilizando `--no-zookeeper`, `--no-shard` y -`--no-long` opciones, respectivamente. - -## Bugs Conocidos {#known-bugs} - -Si conocemos algunos errores que se pueden reproducir fácilmente mediante pruebas funcionales, colocamos pruebas funcionales preparadas en `tests/queries/bugs` directorio. Estas pruebas se moverán a `tests/queries/0_stateless` cuando se corrigen errores. - -## Pruebas de integración {#integration-tests} - -Las pruebas de integración permiten probar ClickHouse en la configuración agrupada y la interacción de ClickHouse con otros servidores como MySQL, Postgres, MongoDB. Son útiles para emular divisiones de red, caídas de paquetes, etc. Estas pruebas se ejecutan bajo Docker y crean múltiples contenedores con varios software. - -Ver `tests/integration/README.md` sobre cómo ejecutar estas pruebas. - -Tenga en cuenta que la integración de ClickHouse con controladores de terceros no se ha probado. Además, actualmente no tenemos pruebas de integración con nuestros controladores JDBC y ODBC. - -## Pruebas unitarias {#unit-tests} - -Las pruebas unitarias son útiles cuando desea probar no ClickHouse como un todo, sino una sola biblioteca o clase aislada. Puede habilitar o deshabilitar la compilación de pruebas con `ENABLE_TESTS` Opción CMake. Las pruebas unitarias (y otros programas de prueba) se encuentran en `tests` subdirectorios en todo el código. Para ejecutar pruebas unitarias, escriba `ninja test`. Algunas pruebas usan `gtest`, pero algunos son solo programas que devuelven un código de salida distinto de cero en caso de fallo de prueba. - -No es necesariamente tener pruebas unitarias si el código ya está cubierto por pruebas funcionales (y las pruebas funcionales suelen ser mucho más simples de usar). - -## Pruebas de rendimiento {#performance-tests} - -Las pruebas de rendimiento permiten medir y comparar el rendimiento de alguna parte aislada de ClickHouse en consultas sintéticas. Las pruebas se encuentran en `tests/performance`. Cada prueba está representada por `.xml` archivo con la descripción del caso de prueba. Las pruebas se ejecutan con `clickhouse performance-test` herramienta (que está incrustada en `clickhouse` binario). Ver `--help` para la invocación. - -Cada prueba ejecuta una o varias consultas (posiblemente con combinaciones de parámetros) en un bucle con algunas condiciones para detener (como “maximum execution speed is not changing in three seconds”) y medir algunas métricas sobre el rendimiento de las consultas (como “maximum execution speed”). Algunas pruebas pueden contener condiciones previas en el conjunto de datos de pruebas precargado. - -Si desea mejorar el rendimiento de ClickHouse en algún escenario, y si se pueden observar mejoras en consultas simples, se recomienda encarecidamente escribir una prueba de rendimiento. Siempre tiene sentido usar `perf top` u otras herramientas de perf durante sus pruebas. - -## Herramientas de prueba y secuencias de comandos {#test-tools-and-scripts} - -Algunos programas en `tests` directorio no son pruebas preparadas, pero son herramientas de prueba. Por ejemplo, para `Lexer` hay una herramienta `src/Parsers/tests/lexer` que solo hacen la tokenización de stdin y escriben el resultado coloreado en stdout. Puede usar este tipo de herramientas como ejemplos de código y para exploración y pruebas manuales. - -También puede colocar un par de archivos `.sh` y `.reference` junto con la herramienta para ejecutarlo en alguna entrada predefinida, entonces el resultado del script se puede comparar con `.reference` file. Este tipo de pruebas no están automatizadas. - -## Pruebas diversas {#miscellaneous-tests} - -Hay pruebas para diccionarios externos ubicados en `tests/external_dictionaries` y para modelos aprendidos a máquina en `tests/external_models`. Estas pruebas no se actualizan y deben transferirse a pruebas de integración. - -Hay una prueba separada para inserciones de quórum. Esta prueba ejecuta el clúster ClickHouse en servidores separados y emula varios casos de fallas: división de red, caída de paquetes (entre nodos ClickHouse, entre ClickHouse y ZooKeeper, entre el servidor ClickHouse y el cliente, etc.), `kill -9`, `kill -STOP` y `kill -CONT` , como [Jepsen](https://aphyr.com/tags/Jepsen). A continuación, la prueba comprueba que todas las inserciones reconocidas se escribieron y todas las inserciones rechazadas no. - -La prueba de quórum fue escrita por un equipo separado antes de que ClickHouse fuera de código abierto. Este equipo ya no trabaja con ClickHouse. La prueba fue escrita accidentalmente en Java. Por estas razones, la prueba de quórum debe reescribirse y trasladarse a pruebas de integración. - -## Pruebas manuales {#manual-testing} - -Cuando desarrolla una nueva característica, es razonable probarla también manualmente. Puede hacerlo con los siguientes pasos: - -Construir ClickHouse. Ejecute ClickHouse desde el terminal: cambie el directorio a `programs/clickhouse-server` y ejecutarlo con `./clickhouse-server`. Se utilizará la configuración (`config.xml`, `users.xml` y archivos dentro de `config.d` y `users.d` directorios) desde el directorio actual de forma predeterminada. Para conectarse al servidor ClickHouse, ejecute `programs/clickhouse-client/clickhouse-client`. - -Tenga en cuenta que todas las herramientas de clickhouse (servidor, cliente, etc.) son solo enlaces simbólicos a un único binario llamado `clickhouse`. Puede encontrar este binario en `programs/clickhouse`. Todas las herramientas también se pueden invocar como `clickhouse tool` en lugar de `clickhouse-tool`. - -Alternativamente, puede instalar el paquete ClickHouse: ya sea una versión estable del repositorio de Yandex o puede crear un paquete para usted con `./release` en la raíz de fuentes de ClickHouse. Luego inicie el servidor con `sudo service clickhouse-server start` (o detener para detener el servidor). Busque registros en `/etc/clickhouse-server/clickhouse-server.log`. - -Cuando ClickHouse ya está instalado en su sistema, puede crear un nuevo `clickhouse` binario y reemplazar el binario existente: - -``` bash -$ sudo service clickhouse-server stop -$ sudo cp ./clickhouse /usr/bin/ -$ sudo service clickhouse-server start -``` - -También puede detener el servidor de clickhouse del sistema y ejecutar el suyo propio con la misma configuración pero con el registro en la terminal: - -``` bash -$ sudo service clickhouse-server stop -$ sudo -u clickhouse /usr/bin/clickhouse server --config-file /etc/clickhouse-server/config.xml -``` - -Ejemplo con gdb: - -``` bash -$ sudo -u clickhouse gdb --args /usr/bin/clickhouse server --config-file /etc/clickhouse-server/config.xml -``` - -Si el servidor de clickhouse del sistema ya se está ejecutando y no desea detenerlo, puede cambiar los números de `config.xml` (o anularlos en un archivo en `config.d` directorio), proporcione la ruta de datos adecuada y ejecútela. - -`clickhouse` binary casi no tiene dependencias y funciona en una amplia gama de distribuciones de Linux. Para probar rápidamente y sucio sus cambios en un servidor, simplemente puede `scp` su fresco construido `clickhouse` binario a su servidor y luego ejecútelo como en los ejemplos anteriores. - -## Entorno de prueba {#testing-environment} - -Antes de publicar la versión como estable, la implementamos en el entorno de prueba. El entorno de prueba es un clúster que procesa 1/39 parte de [El Yandex.Métrica](https://metrica.yandex.com/) datos. Compartimos nuestro entorno de pruebas con Yandex.Equipo de Metrica. ClickHouse se actualiza sin tiempo de inactividad sobre los datos existentes. Nos fijamos en un primer momento que los datos se procesan con éxito sin retraso de tiempo real, la replicación continúan trabajando y no hay problemas visibles para Yandex.Equipo de Metrica. La primera comprobación se puede hacer de la siguiente manera: - -``` sql -SELECT hostName() AS h, any(version()), any(uptime()), max(UTCEventTime), count() FROM remote('example01-01-{1..3}t', merge, hits) WHERE EventDate >= today() - 2 GROUP BY h ORDER BY h; -``` - -En algunos casos también implementamos en el entorno de prueba de nuestros equipos de amigos en Yandex: Market, Cloud, etc. También tenemos algunos servidores de hardware que se utilizan con fines de desarrollo. - -## Pruebas de carga {#load-testing} - -Después de implementar en el entorno de prueba, ejecutamos pruebas de carga con consultas del clúster de producción. Esto se hace manualmente. - -Asegúrese de que ha habilitado `query_log` en su clúster de producción. - -Recopilar el registro de consultas para un día o más: - -``` bash -$ clickhouse-client --query="SELECT DISTINCT query FROM system.query_log WHERE event_date = today() AND query LIKE '%ym:%' AND query NOT LIKE '%system.query_log%' AND type = 2 AND is_initial_query" > queries.tsv -``` - -Este es un ejemplo complicado. `type = 2` filtrará las consultas que se ejecutan correctamente. `query LIKE '%ym:%'` es seleccionar consultas relevantes de Yandex.Métrica. `is_initial_query` es seleccionar solo las consultas iniciadas por el cliente, no por ClickHouse (como partes del procesamiento de consultas distribuidas). - -`scp` este registro en su clúster de prueba y ejecútelo de la siguiente manera: - -``` bash -$ clickhouse benchmark --concurrency 16 < queries.tsv -``` - -(probablemente también desee especificar un `--user`) - -Luego déjalo por una noche o un fin de semana e ir a tomar un descanso. - -Usted debe comprobar que `clickhouse-server` no se bloquea, la huella de memoria está limitada y el rendimiento no se degrada con el tiempo. - -Los tiempos de ejecución de consultas precisos no se registran y no se comparan debido a la alta variabilidad de las consultas y el entorno. - -## Pruebas de construcción {#build-tests} - -Las pruebas de compilación permiten verificar que la compilación no esté rota en varias configuraciones alternativas y en algunos sistemas extranjeros. Las pruebas se encuentran en `ci` directorio. Ejecutan compilación desde la fuente dentro de Docker, Vagrant y, a veces, con `qemu-user-static` dentro de Docker. Estas pruebas están en desarrollo y las ejecuciones de pruebas no están automatizadas. - -Motivación: - -Normalmente lanzamos y ejecutamos todas las pruebas en una sola variante de compilación ClickHouse. Pero hay variantes de construcción alternativas que no se prueban a fondo. Ejemplos: - -- construir en FreeBSD; -- construir en Debian con bibliotecas de paquetes del sistema; -- construir con enlaces compartidos de bibliotecas; -- construir en la plataforma AArch64; -- construir en la plataforma PowerPc. - -Por ejemplo, construir con paquetes del sistema es una mala práctica, porque no podemos garantizar qué versión exacta de paquetes tendrá un sistema. Pero esto es realmente necesario para los mantenedores de Debian. Por esta razón, al menos tenemos que admitir esta variante de construcción. Otro ejemplo: la vinculación compartida es una fuente común de problemas, pero es necesaria para algunos entusiastas. - -Aunque no podemos ejecutar todas las pruebas en todas las variantes de compilaciones, queremos verificar al menos que varias variantes de compilación no estén rotas. Para este propósito utilizamos pruebas de construcción. - -## Pruebas de Compatibilidad de protocolos {#testing-for-protocol-compatibility} - -Cuando ampliamos el protocolo de red ClickHouse, probamos manualmente que el antiguo clickhouse-client funciona con el nuevo clickhouse-server y el nuevo clickhouse-client funciona con el antiguo clickhouse-server (simplemente ejecutando binarios de los paquetes correspondientes). - -## Ayuda del compilador {#help-from-the-compiler} - -Código principal de ClickHouse (que se encuentra en `dbms` directorio) se construye con `-Wall -Wextra -Werror` y con algunas advertencias habilitadas adicionales. Aunque estas opciones no están habilitadas para bibliotecas de terceros. - -Clang tiene advertencias aún más útiles: puedes buscarlas con `-Weverything` y elige algo para la compilación predeterminada. - -Para las compilaciones de producción, se usa gcc (todavía genera un código ligeramente más eficiente que clang). Para el desarrollo, el clang suele ser más conveniente de usar. Puede construir en su propia máquina con el modo de depuración (para ahorrar batería de su computadora portátil), pero tenga en cuenta que el compilador puede generar más advertencias con `-O3` debido a un mejor flujo de control y análisis entre procedimientos. Al construir con clang con el modo de depuración, la versión de depuración de `libc++` se utiliza que permite detectar más errores en tiempo de ejecución. - -## Desinfectantes {#sanitizers} - -**Dirección desinfectante**. -Ejecutamos pruebas funcionales y de integración bajo ASan por compromiso. - -**Valgrind (Memcheck)**. -Realizamos pruebas funcionales bajo Valgrind durante la noche. Se tarda varias horas. Actualmente hay un falso positivo conocido en `re2` biblioteca, ver [este artículo](https://research.swtch.com/sparse). - -**Desinfectante de comportamiento indefinido.** -Ejecutamos pruebas funcionales y de integración bajo ASan por compromiso. - -**Desinfectante de hilo**. -Ejecutamos pruebas funcionales bajo TSan por compromiso. Todavía no ejecutamos pruebas de integración bajo TSan por compromiso. - -**Desinfectante de memoria**. -Actualmente todavía no usamos MSan. - -**Asignador de depuración.** -Versión de depuración de `jemalloc` se utiliza para la compilación de depuración. - -## Fuzzing {#fuzzing} - -ClickHouse fuzzing se implementa tanto usando [LibFuzzer](https://llvm.org/docs/LibFuzzer.html) y consultas SQL aleatorias. -Todas las pruebas de fuzz deben realizarse con desinfectantes (Dirección y Undefined). - -LibFuzzer se usa para pruebas de fuzz aisladas del código de la biblioteca. Fuzzers se implementan como parte del código de prueba y tienen “_fuzzer” nombre postfixes. -El ejemplo de Fuzzer se puede encontrar en `src/Parsers/tests/lexer_fuzzer.cpp`. Las configuraciones, diccionarios y corpus específicos de LibFuzzer se almacenan en `tests/fuzz`. -Le recomendamos que escriba pruebas fuzz para cada funcionalidad que maneje la entrada del usuario. - -Fuzzers no se construyen de forma predeterminada. Para construir fuzzers ambos `-DENABLE_FUZZING=1` y `-DENABLE_TESTS=1` se deben establecer opciones. -Recomendamos deshabilitar Jemalloc mientras se construyen fuzzers. Configuración utilizada para integrar -Google OSS-Fuzz se puede encontrar en `docker/fuzz`. - -También usamos una prueba de fuzz simple para generar consultas SQL aleatorias y verificar que el servidor no muera al ejecutarlas. -Lo puedes encontrar en `00746_sql_fuzzy.pl`. Esta prueba debe ejecutarse de forma continua (de la noche a la mañana y más). - -## Auditoría de seguridad {#security-audit} - -La gente de Yandex Security Team hace una visión general básica de las capacidades de ClickHouse desde el punto de vista de la seguridad. - -## Analizadores estáticos {#static-analyzers} - -Corremos `PVS-Studio` por compromiso. Hemos evaluado `clang-tidy`, `Coverity`, `cppcheck`, `PVS-Studio`, `tscancode`. Encontrará instrucciones de uso en `tests/instructions/` directorio. También puedes leer [el artículo en ruso](https://habr.com/company/yandex/blog/342018/). - -Si usted usa `CLion` como IDE, puede aprovechar algunos `clang-tidy` comprueba fuera de la caja. - -## Endurecer {#hardening} - -`FORTIFY_SOURCE` se utiliza de forma predeterminada. Es casi inútil, pero todavía tiene sentido en casos raros y no lo desactivamos. - -## Estilo de código {#code-style} - -Se describen las reglas de estilo de código [aqui](https://clickhouse.tech/docs/en/development/style/). - -Para comprobar si hay algunas violaciones de estilo comunes, puede usar `utils/check-style` script. - -Para forzar el estilo adecuado de su código, puede usar `clang-format`. File `.clang-format` se encuentra en la raíz de las fuentes. Se corresponde principalmente con nuestro estilo de código real. Pero no se recomienda aplicar `clang-format` a los archivos existentes porque empeora el formato. Usted puede utilizar `clang-format-diff` herramienta que puede encontrar en el repositorio de origen clang. - -Alternativamente, puede intentar `uncrustify` herramienta para reformatear su código. La configuración está en `uncrustify.cfg` en la raíz de las fuentes. Es menos probado que `clang-format`. - -`CLion` tiene su propio formateador de código que debe ajustarse para nuestro estilo de código. - -## Pruebas Metrica B2B {#metrica-b2b-tests} - -Cada lanzamiento de ClickHouse se prueba con los motores Yandex Metrica y AppMetrica. Las pruebas y las versiones estables de ClickHouse se implementan en máquinas virtuales y se ejecutan con una copia pequeña del motor Metrica que procesa una muestra fija de datos de entrada. A continuación, los resultados de dos instancias del motor Metrica se comparan juntos. - -Estas pruebas son automatizadas por un equipo separado. Debido a la gran cantidad de piezas móviles, las pruebas fallan la mayor parte del tiempo por razones completamente no relacionadas, que son muy difíciles de descubrir. Lo más probable es que estas pruebas tengan un valor negativo para nosotros. Sin embargo, se demostró que estas pruebas son útiles en aproximadamente una o dos veces de cada cientos. - -## Cobertura de prueba {#test-coverage} - -A partir de julio de 2018, no realizamos un seguimiento de la cobertura de las pruebas. - -## Automatización de pruebas {#test-automation} - -Realizamos pruebas con el CI interno de Yandex y el sistema de automatización de trabajos llamado “Sandbox”. - -Los trabajos de compilación y las pruebas se ejecutan en Sandbox por confirmación. Los paquetes resultantes y los resultados de las pruebas se publican en GitHub y se pueden descargar mediante enlaces directos. Los artefactos se almacenan eternamente. Cuando envías una solicitud de extracción en GitHub, la etiquetamos como “can be tested” y nuestro sistema CI construirá paquetes ClickHouse (liberación, depuración, con desinfectante de direcciones, etc.) para usted. - -No usamos Travis CI debido al límite de tiempo y potencia computacional. -No usamos Jenkins. Se usó antes y ahora estamos felices de no estar usando Jenkins. - -[Artículo Original](https://clickhouse.tech/docs/en/development/tests/) diff --git a/docs/es/development/tests.md b/docs/es/development/tests.md new file mode 120000 index 00000000000..c03d36c3916 --- /dev/null +++ b/docs/es/development/tests.md @@ -0,0 +1 @@ +../../en/development/tests.md \ No newline at end of file diff --git a/docs/fa/development/tests.md b/docs/fa/development/tests.md deleted file mode 100644 index abab3230e2f..00000000000 --- a/docs/fa/development/tests.md +++ /dev/null @@ -1,262 +0,0 @@ ---- -machine_translated: true -machine_translated_rev: 72537a2d527c63c07aa5d2361a8829f3895cf2bd -toc_priority: 69 -toc_title: "\u0646\u062D\u0648\u0647 \u0627\u062C\u0631\u0627\u06CC \u062A\u0633\u062A\ -

-هر تست عملکردی یک یا چند نمایش داده شد به سرور در حال اجرا تاتر می فرستد و نتیجه را با مرجع مقایسه می کند. - -تست ها در واقع `queries` فهرست راهنما. دو زیرشاخه وجود دارد: `stateless` و `stateful`. تست های بدون تابعیت بدون هیچ گونه داده های تست پیش بارگذاری شده نمایش داده می شوند-اغلب مجموعه داده های مصنوعی کوچک را در پرواز در داخل تست خود ایجاد می کنند. تست های نفرت انگیز نیاز به داده های تست از قبل نصب شده از یاندکس.متریکا و در دسترس عموم نیست. ما تمایل به استفاده از تنها `stateless` تست ها و جلوگیری از اضافه کردن جدید `stateful` تستها - -هر تست می تواند یکی از دو نوع باشد: `.sql` و `.sh`. `.sql` تست اسکریپت ساده مربع است که به لوله کشی است `clickhouse-client --multiquery --testmode`. `.sh` تست یک اسکریپت است که به خودی خود اجرا است. - -برای اجرای تمام تست ها استفاده کنید `clickhouse-test` ابزار. نگاه کن `--help` برای لیستی از گزینه های ممکن. شما به سادگی می توانید تمام تست ها را اجرا کنید یا زیر مجموعه ای از تست های فیلتر شده توسط زیر رشته را در نام تست اجرا کنید: `./clickhouse-test substring`. - -ساده ترین راه برای فراخوانی تست های کاربردی کپی است `clickhouse-client` به `/usr/bin/` فرار کن `clickhouse-server` و سپس اجرا کنید `./clickhouse-test` از دایرکتوری خود را. - -برای اضافه کردن تست جدید, ایجاد یک `.sql` یا `.sh` پرونده در `queries/0_stateless` فهرست راهنما را به صورت دستی بررسی کنید و سپس تولید کنید `.reference` پرونده به روش زیر: `clickhouse-client -n --testmode < 00000_test.sql > 00000_test.reference` یا `./00000_test.sh > ./00000_test.reference`. - -تست باید استفاده کنید (ساختن, قطره, و غیره) تنها جداول در `test` پایگاه داده است که فرض بر این است که از قبل ایجاد می شود; همچنین تست می توانید جداول موقت استفاده. - -اگر شما می خواهید به استفاده از نمایش داده شد توزیع شده در تست های کاربردی, شما می توانید اهرم `remote` تابع جدول با `127.0.0.{1..2}` یا شما می توانید خوشه تست از پیش تعریف شده در فایل پیکربندی سرور مانند استفاده کنید `test_shard_localhost`. - -برخی از تست ها با مشخص شده اند `zookeeper`, `shard` یا `long` در نام خود. -`zookeeper` برای تست هایی است که از باغ وحش استفاده می کنند. `shard` برای تست هایی است که -نیاز به سرور برای گوش دادن `127.0.0.*`; `distributed` یا `global` همان -معنی. `long` برای تست هایی است که کمی طولانی تر اجرا می شوند که یک ثانیه. شما می توانید -غیر فعال کردن این گروه از تست با استفاده از `--no-zookeeper`, `--no-shard` و -`--no-long` گزینه, به ترتیب. - -## اشکالات شناخته شده {#known-bugs} - -اگر ما می دانیم برخی از اشکالات است که می تواند به راحتی توسط تست های کاربردی تکثیر, ما تست های عملکردی تهیه شده در `tests/queries/bugs` فهرست راهنما. این تست خواهد شد به نقل مکان کرد `tests/queries/0_stateless` هنگامی که اشکالات ثابت هستند. - -## تست های ادغام {#integration-tests} - -ادغام آزمون اجازه می دهد برای تست ClickHouse در خوشه پیکربندی و ClickHouse تعامل با سرور های دیگر مانند MySQL, Postgres, MongoDB. مفید برای تقلید انشعابات شبکه قطره بسته و غیره هستند. این تست ها تحت کارگر بارانداز اجرا و ایجاد ظروف متعدد با نرم افزار های مختلف. - -ببینید `tests/integration/README.md` در مورد چگونگی اجرای این تست. - -توجه داشته باشید که ادغام کلیک با رانندگان شخص ثالث تست نشده است. همچنین ما در حال حاضر تست های یکپارچه سازی با رانندگان جی بی سی و بی سی ما ندارد. - -## تست های واحد {#unit-tests} - -تست واحد مفید هستند که شما می خواهید برای تست نیست خانه کلیک به عنوان یک کل, اما یک کتابخانه جدا شده و یا کلاس. شما می توانید ساخت تست ها را فعال یا غیر فعال کنید `ENABLE_TESTS` گزینه کیک. تست واحد (و دیگر برنامه های تست) در واقع `tests` زیرشاخه در سراسر کد. برای اجرای تست واحد, نوع `ninja test`. برخی از تست ها استفاده می کنند `gtest`, اما برخی فقط برنامه هایی که بازگشت کد خروج غیر صفر در شکست تست. - -این لزوما به تست واحد اگر کد در حال حاضر توسط تست های کاربردی تحت پوشش (و تست های کاربردی معمولا بسیار ساده تر برای استفاده). - -## تست های عملکرد {#performance-tests} - -تست های عملکرد اجازه می دهد برای اندازه گیری و مقایسه عملکرد برخی از بخش جدا شده از خانه رعیتی در نمایش داده شد مصنوعی. تست ها در واقع `tests/performance`. هر تست توسط نمایندگی `.xml` فایل با شرح مورد تست. تست ها با اجرا `clickhouse performance-test` ابزار (که در تعبیه شده است `clickhouse` دودویی). ببینید `--help` برای نیایش. - -هر تست یک یا چند نمایش داده شد (احتمالا با ترکیبی از پارامترهای) در یک حلقه با برخی از شرایط برای توقف (مانند “maximum execution speed is not changing in three seconds”) و اندازه گیری برخی از معیارهای مورد عملکرد پرس و جو (مانند “maximum execution speed”). برخی از تست ها می توانند پیش شرط ها را در مجموعه داده های تست پیش بارگذاری شده داشته باشند. - -اگر شما می خواهید برای بهبود عملکرد تاتر در برخی از سناریو, و اگر پیشرفت را می توان در نمایش داده شد ساده مشاهده, بسیار توصیه می شود برای نوشتن یک تست عملکرد. همیشه حس می کند به استفاده از `perf top` و یا دیگر ابزار دقیق در طول تست های خود را. - -## ابزار تست و اسکریپت {#test-tools-and-scripts} - -برخی از برنامه ها در `tests` دایرکتوری تست تهیه نشده, اما ابزار تست. مثلا, برای `Lexer` یک ابزار وجود دارد `src/Parsers/tests/lexer` این فقط تقلید از استدین را انجام می دهد و نتیجه رنگی را به انحراف می نویسد. شما می توانید از این نوع ابزار به عنوان نمونه کد و برای اکتشاف و تست دستی استفاده کنید. - -شما همچنین می توانید جفت فایل قرار دهید `.sh` و `.reference` همراه با ابزار برای اجرا در برخی از ورودی از پیش تعریف شده - سپس نتیجه اسکریپت را می توان به مقایسه `.reference` پرونده. این نوع تست ها خودکار نیستند. - -## تست های متفرقه {#miscellaneous-tests} - -تست برای لغت نامه های خارجی واقع در وجود دارد `tests/external_dictionaries` و برای مدل های ماشین یاد گرفته شده در `tests/external_models`. این تست ها به روز نمی شوند و باید به تست های ادغام منتقل شوند. - -تست جداگانه برای درج حد نصاب وجود دارد. این اجرای آزمون ClickHouse خوشه در سرورهای جداگانه و شبیه سازی شکست های مختلف در موارد: شبکه تقسیم بسته رها کردن (بین ClickHouse گره بین ClickHouse و باغ وحش بین ClickHouse سرور و کلاینت ، ), `kill -9`, `kill -STOP` و `kill -CONT` مثل [جپسن](https://aphyr.com/tags/Jepsen). سپس چک تست که همه درج اذعان نوشته شده بود و همه درج رد شد. - -تست حد نصاب توسط تیم جداگانه نوشته شده بود قبل از کلیک باز منابع بود. این تیم دیگر با کلیکهاوس کار. تست به طور تصادفی در جاوا نوشته شده بود. به این دلایل, تست حد نصاب باید بازنویسی شود و به تست ادغام نقل مکان کرد. - -## تست دستی {#manual-testing} - -هنگامی که شما توسعه یک ویژگی جدید معقول نیز دستی تست است. شما می توانید این کار را با مراحل زیر انجام دهید: - -ساخت خانه کلیک. اجرای کلیک از ترمینال: تغییر دایرکتوری به `programs/clickhouse-server` و با `./clickhouse-server`. این پیکربندی استفاده کنید (`config.xml`, `users.xml` و فایل ها در `config.d` و `users.d` دایرکتوری ها) از دایرکتوری جاری به طور پیش فرض. برای اتصال به سرور کلیک اجرا کنید `programs/clickhouse-client/clickhouse-client`. - -توجه داشته باشید که تمام clickhouse ابزار (سرور مشتری و غیره) فقط symlinks به یک باینری به نام `clickhouse`. شما می توانید این دودویی در `programs/clickhouse`. همه ابزار همچنین می توانید به عنوان استناد شود `clickhouse tool` به جای `clickhouse-tool`. - -متناوبا شما می توانید بسته بندی کلیک را نصب کنید: در هر صورت انتشار پایدار از مخزن یاندکس و یا شما می توانید بسته را برای خودتان با ساخت `./release` در منابع کلیک خانه ریشه. سپس سرور را با شروع `sudo service clickhouse-server start` (یا توقف برای متوقف کردن سرور). به دنبال سیاهههای مربوط در `/etc/clickhouse-server/clickhouse-server.log`. - -هنگامی که تاتر در حال حاضر بر روی سیستم شما نصب شده, شما می توانید جدید ساخت `clickhouse` دودویی و جایگزین باینری موجود: - -``` bash -$ sudo service clickhouse-server stop -$ sudo cp ./clickhouse /usr/bin/ -$ sudo service clickhouse-server start -``` - -همچنین شما می توانید سیستم کلیک سرور را متوقف و اجرا خود را با همان پیکربندی اما با ورود به ترمینال: - -``` bash -$ sudo service clickhouse-server stop -$ sudo -u clickhouse /usr/bin/clickhouse server --config-file /etc/clickhouse-server/config.xml -``` - -به عنوان مثال با دیابت بارداری: - -``` bash -$ sudo -u clickhouse gdb --args /usr/bin/clickhouse server --config-file /etc/clickhouse-server/config.xml -``` - -اگر سیستم کلیک-سرور در حال اجرا است و شما نمی خواهید برای متوقف کردن, شما می توانید شماره پورت در خود تغییر دهید `config.xml` (یا نادیده گرفتن در یک فایل در `config.d` فهرست راهنما) مسیر داده مناسب را فراهم کرده و اجرا کنید. - -`clickhouse` دودویی تقریبا هیچ وابستگی و کار در سراسر طیف گسترده ای از توزیع های لینوکس. برای تست سریع و کثیف تغییرات خود را بر روی یک سرور, شما به سادگی می توانید `scp` تازه ساخته شده است `clickhouse` باینری به سرور شما و سپس به عنوان مثال بالا اجرا شود. - -## محیط تست {#testing-environment} - -قبل از انتشار انتشار به عنوان پایدار ما را در محیط تست استقرار. محیط تست یک خوشه است که بخشی از 1/39 را پردازش می کند [یاندکسمتریکا](https://metrica.yandex.com/) داده ها. ما محیط تست خود را با یاندکس به اشتراک می گذاریم.تیم متریکا تاتر بدون خرابی در بالای داده های موجود به روز رسانی. ما در ابتدا نگاه کنید که داده ها با موفقیت و بدون عقب مانده از زمان واقعی پردازش, تکرار ادامه کار و هیچ مشکلی برای یاندکس قابل مشاهده وجود دارد.تیم متریکا اولین چک را می توان در راه زیر انجام داد: - -``` sql -SELECT hostName() AS h, any(version()), any(uptime()), max(UTCEventTime), count() FROM remote('example01-01-{1..3}t', merge, hits) WHERE EventDate >= today() - 2 GROUP BY h ORDER BY h; -``` - -در برخی موارد ما نیز به تست محیط زیست از تیم های دوست ما در یاندکس استقرار: بازار, ابر, و غیره. همچنین در حال حاضر برخی از سرورهای سخت افزاری است که برای اهداف توسعه استفاده می شود. - -## تست بار {#load-testing} - -پس از استقرار به محیط تست ما تست بار با نمایش داده شد از خوشه تولید را اجرا کنید. این کار به صورت دستی انجام می شود. - -اطمینان حاصل کنید که شما را فعال کرده اند `query_log` در خوشه تولید خود را. - -جمع کردن گزارش پرس و جو برای یک روز یا بیشتر: - -``` bash -$ clickhouse-client --query="SELECT DISTINCT query FROM system.query_log WHERE event_date = today() AND query LIKE '%ym:%' AND query NOT LIKE '%system.query_log%' AND type = 2 AND is_initial_query" > queries.tsv -``` - -این یک مثال راه پیچیده است. `type = 2` نمایش داده شد که با موفقیت اجرا فیلتر کنید. `query LIKE '%ym:%'` است برای انتخاب نمایش داده شد مربوطه از یاندکس.متریکا `is_initial_query` است را انتخاب کنید تنها نمایش داده شد که توسط مشتری شروع, نه با کلیک خود (به عنوان بخش هایی از پردازش پرس و جو توزیع). - -`scp` این ورود به خوشه تست خود را و اجرا به شرح زیر است: - -``` bash -$ clickhouse benchmark --concurrency 16 < queries.tsv -``` - -(احتمالا شما همچنین می خواهید برای مشخص کردن یک `--user`) - -پس یه شب یا هفته ولش کن و برو استراحت کن - -شما باید بررسی کنید که `clickhouse-server` سقوط نمی کند, رد پای حافظه محدود است و عملکرد در طول زمان تنزل نمی. - -زمان اجرای پرس و جو دقیق ثبت نشده است و با توجه به تنوع بالا از نمایش داده شد و محیط زیست در مقایسه نیست. - -## ساخت تست {#build-tests} - -تست های ساخت اجازه می دهد تا بررسی کنید که ساخت در تنظیمات مختلف جایگزین و در برخی از سیستم های خارجی شکسته نمی شود. تست ها در واقع `ci` فهرست راهنما. ساخت از منبع داخل کارگر بارانداز ولگرد و گاهی با اجرا می شوند `qemu-user-static` در داخل کارگر بارانداز. این تست ها در حال توسعه هستند و تست اجرا می شود خودکار نیست. - -انگیزه: - -به طور معمول ما انتشار و اجرای تمام تست بر روی یک نوع واحد از ساخت تاتر. اما انواع ساخت جایگزین است که به طور کامل تست شده وجود دارد. مثالها: - -- ساخت در بورس; -- ساخت در دبیان با کتابخانه ها از بسته های سیستم; -- ساخت با لینک مشترک از کتابخانه ها; -- ساخت پلت فرم AArch64; -- ساخت بر روی پلت فرم پاور. - -مثلا, ساخت با بسته های سیستم عمل بد است, چرا که ما نمی تواند تضمین کند که چه نسخه دقیق از بسته های یک سیستم باید. اما این واقعا توسط نگهداری دبیان مورد نیاز است. به همین دلیل ما حداقل باید برای حمایت از این نوع ساخت. مثال دیگر: ارتباط مشترک یک منبع مشترک از مشکل است, اما برای برخی از علاقه مندان مورد نیاز است. - -هر چند ما می توانیم تمام تست در همه نوع از ایجاد اجرا کنید, ما می خواهیم برای بررسی حداقل که انواع ساخت های مختلف شکسته نمی. برای این منظور ما از تست های ساخت استفاده می کنیم. - -## تست برای سازگاری پروتکل {#testing-for-protocol-compatibility} - -هنگامی که ما گسترش ClickHouse پروتکل شبکه ما تست دستی که clickhouse-مشتری با این نسخهها کار جدید clickhouse-سرور و جدید clickhouse-مشتری با این نسخهها کار با clickhouse-سرور (به سادگی با در حال اجرا فایل های باینری از مربوطه بسته). - -## کمک از کامپایلر {#help-from-the-compiler} - -کد اصلی کلیک (که در واقع `dbms` فهرست راهنما) با ساخته شده است `-Wall -Wextra -Werror` و با برخی از هشدارهای اضافی را فعال کنید. اگر چه این گزینه ها برای کتابخانه های شخص ثالث فعال نیست. - -کلانگ هشدارهای بیشتری دارد - شما می توانید با `-Weverything` و انتخاب چیزی به طور پیش فرض ساخت. - -برای تولید ساخت, شورای همکاری خلیج فارس استفاده می شود (هنوز تولید کد کمی موثر تر از صدای جرنگ جرنگ). برای توسعه, صدای جرنگ جرنگ است که معمولا راحت تر به استفاده از. شما می توانید بر روی دستگاه خود را با حالت اشکال زدایی ساخت (برای صرفه جویی در باتری لپ تاپ خود را), اما لطفا توجه داشته باشید که کامپایلر قادر به تولید هشدارهای بیشتر با است `-O3` با توجه به جریان کنترل بهتر و تجزیه و تحلیل بین روش. هنگام ساخت با صدای جرنگ جرنگ, `libc++` به جای استفاده `libstdc++` و هنگامی که ساختمان با حالت اشکال زدایی, نسخه اشکال زدایی از `libc++` استفاده شده است که اجازه می دهد تا برای گرفتن خطاهای بیشتر در زمان اجرا. -

-# ClickHouse Test {#clickhouse-testing} - -## Les Tests Fonctionnels {#functional-tests} - -Les tests fonctionnels sont les plus simples et pratiques à utiliser. La plupart des fonctionnalités de ClickHouse peuvent être testées avec des tests fonctionnels et elles sont obligatoires à utiliser pour chaque changement de code de ClickHouse qui peut être testé de cette façon. - -Chaque test fonctionnel envoie une ou plusieurs requêtes au serveur clickhouse en cours d'exécution et compare le résultat avec la référence. - -Les Tests sont situés dans `queries` répertoire. Il y a deux sous-répertoires: `stateless` et `stateful`. Les tests sans état exécutent des requêtes sans données de test préchargées - ils créent souvent de petits ensembles de données synthétiques à la volée, dans le test lui-même. Les tests avec État nécessitent des données de test préchargées de Yandex.Metrica et non disponible pour le grand public. Nous avons tendance à utiliser uniquement `stateless` tests et éviter d'ajouter de nouveaux `stateful` test. - -Chaque test peut être de deux types: `.sql` et `.sh`. `.sql` test est le script SQL simple qui est canalisé vers `clickhouse-client --multiquery --testmode`. `.sh` test est un script qui est exécuté par lui-même. - -Pour exécuter tous les tests, utilisez `clickhouse-test` outil. Regarder `--help` pour la liste des options possibles. Vous pouvez simplement exécuter tous les tests ou exécuter un sous ensemble de tests filtrés par sous chaîne dans le nom du test: `./clickhouse-test substring`. - -Le moyen le plus simple d'invoquer des tests fonctionnels est de copier `clickhouse-client` de `/usr/bin/`, exécuter `clickhouse-server` et puis exécutez `./clickhouse-test` à partir de son propre répertoire. - -Pour ajouter un nouveau test, créez un `.sql` ou `.sh` fichier dans `queries/0_stateless` répertoire, vérifiez-le manuellement, puis générez `.reference` fichier de la façon suivante: `clickhouse-client -n --testmode < 00000_test.sql > 00000_test.reference` ou `./00000_test.sh > ./00000_test.reference`. - -Les Tests doivent utiliser (create, drop, etc) uniquement des tables dans `test` base de données supposée être créée au préalable; les tests peuvent également utiliser des tables temporaires. - -Si vous souhaitez utiliser des requêtes distribuées dans les tests fonctionnels, vous pouvez tirer parti de `remote` fonction de table avec `127.0.0.{1..2}` ou vous pouvez utiliser des clusters de test prédéfinis dans le fichier de configuration du serveur comme `test_shard_localhost`. - -Certains tests sont marqués avec `zookeeper`, `shard` ou `long` en leurs noms. -`zookeeper` est pour les tests qui utilisent ZooKeeper. `shard` est pour les tests -nécessite l'écoute du serveur `127.0.0.*`; `distributed` ou `global` avoir le même -sens. `long` est pour les tests qui s'exécutent légèrement plus longtemps qu'une seconde. Vous pouvez -désactivez ces groupes de tests en utilisant `--no-zookeeper`, `--no-shard` et -`--no-long` options, respectivement. - -## Bugs Connus {#known-bugs} - -Si nous connaissons des bugs qui peuvent être facilement reproduits par des tests fonctionnels, nous plaçons des tests fonctionnels préparés dans `tests/queries/bugs` répertoire. Ces tests seront déplacés à `tests/queries/0_stateless` quand les bugs sont corrigés. - -## Les Tests D'Intégration {#integration-tests} - -Les tests d'intégration permettent de tester ClickHouse en configuration cluster et clickhouse interaction avec D'autres serveurs comme MySQL, Postgres, MongoDB. Ils sont utiles pour émuler les splits réseau, les chutes de paquets, etc. Ces tests sont exécutés sous Docker et créent plusieurs conteneurs avec divers logiciels. - -Voir `tests/integration/README.md` sur la façon d'exécuter ces tests. - -Notez que l'intégration de ClickHouse avec des pilotes tiers n'est pas testée. De plus, nous n'avons actuellement pas de tests d'intégration avec nos pilotes JDBC et ODBC. - -## Les Tests Unitaires {#unit-tests} - -Les tests unitaires sont utiles lorsque vous voulez tester non pas le ClickHouse dans son ensemble, mais une seule bibliothèque ou classe isolée. Vous pouvez activer ou désactiver la génération de tests avec `ENABLE_TESTS` Option CMake. Les tests unitaires (et autres programmes de test) sont situés dans `tests` sous-répertoires à travers le code. Pour exécuter des tests unitaires, tapez `ninja test`. Certains tests utilisent `gtest`, mais certains ne sont que des programmes qui renvoient un code de sortie non nul en cas d'échec du test. - -Ce n'est pas nécessairement d'avoir des tests unitaires si le code est déjà couvert par des tests fonctionnels (et les tests fonctionnels sont généralement beaucoup plus simples à utiliser). - -## Tests De Performance {#performance-tests} - -Les tests de Performance permettent de mesurer et de comparer les performances d'une partie isolée de ClickHouse sur des requêtes synthétiques. Les Tests sont situés à `tests/performance`. Chaque test est représenté par `.xml` fichier avec description du cas de test. Les Tests sont exécutés avec `clickhouse performance-test` outil (qui est incorporé dans `clickhouse` binaire). Voir `--help` pour l'invocation. - -Chaque essai d'exécuter une ou plusieurs requêtes (éventuellement avec des combinaisons de paramètres) dans une boucle avec certaines conditions pour l'arrêt (comme “maximum execution speed is not changing in three seconds”) et mesurer certaines mesures sur les performances de la requête (comme “maximum execution speed”). Certains tests peuvent contenir des conditions préalables sur un ensemble de données de test préchargé. - -Si vous souhaitez améliorer les performances de ClickHouse dans certains scénarios, et si des améliorations peuvent être observées sur des requêtes simples, il est fortement recommandé d'écrire un test de performance. Il est toujours logique d'utiliser `perf top` ou d'autres outils perf pendant vos tests. - -## Outils et Scripts de Test {#test-tools-and-scripts} - -Certains programmes dans `tests` directory ne sont pas des tests préparés, mais sont des outils de test. Par exemple, pour `Lexer` il est un outil `src/Parsers/tests/lexer` Cela fait juste la tokenisation de stdin et écrit le résultat colorisé dans stdout. Vous pouvez utiliser ce genre d'outils comme exemples de code et pour l'exploration et les tests manuels. - -Vous pouvez également placer une paire de fichiers `.sh` et `.reference` avec l'outil pour l'exécuter sur une entrée prédéfinie - alors le résultat du script peut être comparé à `.reference` fichier. Ce genre de tests ne sont pas automatisés. - -## Divers Tests {#miscellaneous-tests} - -Il existe des tests pour les dictionnaires externes situés à `tests/external_dictionaries` et pour machine appris modèles dans `tests/external_models`. Ces tests ne sont pas mis à jour et doivent être transférés aux tests d'intégration. - -Il y a un test séparé pour les inserts de quorum. Ce test exécute le cluster ClickHouse sur des serveurs séparés et émule divers cas d'échec: scission réseau, chute de paquets (entre les nœuds ClickHouse, entre Clickhouse et ZooKeeper, entre le serveur ClickHouse et le client, etc.), `kill -9`, `kill -STOP` et `kill -CONT` , comme [Jepsen](https://aphyr.com/tags/Jepsen). Ensuite, le test vérifie que toutes les insertions reconnues ont été écrites et que toutes les insertions rejetées ne l'ont pas été. - -Le test de Quorum a été écrit par une équipe distincte avant que ClickHouse ne soit open-source. Cette équipe ne travaille plus avec ClickHouse. Test a été écrit accidentellement en Java. Pour ces raisons, quorum test doit être réécrit et déplacé vers tests d'intégration. - -## Les Tests Manuels {#manual-testing} - -Lorsque vous développez une nouvelle fonctionnalité, il est raisonnable de tester également manuellement. Vous pouvez le faire avec les étapes suivantes: - -Construire ClickHouse. Exécuter ClickHouse à partir du terminal: changer le répertoire à `programs/clickhouse-server` et de l'exécuter avec `./clickhouse-server`. Il utilisera la configuration (`config.xml`, `users.xml` et les fichiers à l'intérieur `config.d` et `users.d` répertoires) à partir du répertoire courant par défaut. Pour vous connecter au serveur ClickHouse, exécutez `programs/clickhouse-client/clickhouse-client`. - -Notez que tous les outils clickhouse (serveur, client, etc.) ne sont que des liens symboliques vers un seul binaire nommé `clickhouse`. Vous pouvez trouver ce binaire à `programs/clickhouse`. Tous les outils peuvent également être invoquée comme `clickhouse tool` plutôt `clickhouse-tool`. - -Alternativement, vous pouvez installer le paquet ClickHouse: soit une version stable du référentiel Yandex, soit vous pouvez créer un paquet pour vous-même avec `./release` dans les sources de ClickHouse racine. Puis démarrez le serveur avec `sudo service clickhouse-server start` (ou stop pour arrêter le serveur). Rechercher des journaux à `/etc/clickhouse-server/clickhouse-server.log`. - -Lorsque ClickHouse est déjà installé sur votre système, vous pouvez créer un nouveau `clickhouse` binaire et remplacer le binaire: - -``` bash -$ sudo service clickhouse-server stop -$ sudo cp ./clickhouse /usr/bin/ -$ sudo service clickhouse-server start -``` - -Vous pouvez également arrêter system clickhouse-server et exécuter le vôtre avec la même configuration mais en vous connectant au terminal: - -``` bash -$ sudo service clickhouse-server stop -$ sudo -u clickhouse /usr/bin/clickhouse server --config-file /etc/clickhouse-server/config.xml -``` - -Exemple avec gdb: - -``` bash -$ sudo -u clickhouse gdb --args /usr/bin/clickhouse server --config-file /etc/clickhouse-server/config.xml -``` - -Si le système clickhouse-server est déjà en cours d'exécution et que vous ne voulez pas l'arrêter, vous pouvez modifier les numéros de port dans votre `config.xml` (ou de les remplacer dans un fichier `config.d` répertoire), fournissez le chemin de données approprié, et exécutez-le. - -`clickhouse` binary n'a presque aucune dépendance et fonctionne sur un large éventail de distributions Linux. Rapide et sale de tester vos modifications sur un serveur, vous pouvez simplement `scp` votre douce construite `clickhouse` binaire à votre serveur et ensuite l'exécuter comme dans les exemples ci-dessus. - -## L'Environnement De Test {#testing-environment} - -Avant de publier la version stable, nous la déployons sur l'environnement de test. L'environnement de test est un cluster processus 1/39 partie de [Yandex.Metrica](https://metrica.yandex.com/) données. Nous partageons notre environnement de test avec Yandex.Metrica de l'équipe. ClickHouse est mis à niveau sans temps d'arrêt au-dessus des données existantes. Nous regardons d'abord que les données sont traitées avec succès sans retard par rapport au temps réel, la réplication continue à fonctionner et il n'y a pas de problèmes visibles pour Yandex.Metrica de l'équipe. Première vérification peut être effectuée de la façon suivante: - -``` sql -SELECT hostName() AS h, any(version()), any(uptime()), max(UTCEventTime), count() FROM remote('example01-01-{1..3}t', merge, hits) WHERE EventDate >= today() - 2 GROUP BY h ORDER BY h; -``` - -Dans certains cas, nous déployons également à l'environnement de test de nos équipes d'amis dans Yandex: marché, Cloud, etc. Nous avons également des serveurs matériels qui sont utilisés à des fins de développement. - -## Les Tests De Charge {#load-testing} - -Après le déploiement dans l'environnement de test, nous exécutons des tests de charge avec des requêtes du cluster de production. Ceci est fait manuellement. - -Assurez-vous que vous avez activé `query_log` sur votre cluster de production. - -Recueillir le journal des requêtes pour une journée ou plus: - -``` bash -$ clickhouse-client --query="SELECT DISTINCT query FROM system.query_log WHERE event_date = today() AND query LIKE '%ym:%' AND query NOT LIKE '%system.query_log%' AND type = 2 AND is_initial_query" > queries.tsv -``` - -C'est une façon compliquée exemple. `type = 2` filtrera les requêtes exécutées avec succès. `query LIKE '%ym:%'` est de sélectionner les requêtes de Yandex.Metrica. `is_initial_query` est de sélectionner uniquement les requêtes initiées par le client, pas par ClickHouse lui-même (en tant que partie du traitement de requête distribué). - -`scp` ce journal à votre cluster de test et l'exécuter comme suit: - -``` bash -$ clickhouse benchmark --concurrency 16 < queries.tsv -``` - -(probablement vous voulez aussi spécifier un `--user`) - -Ensuite, laissez-le pour une nuit ou un week-end et allez vous reposer. - -Tu devrais vérifier ça `clickhouse-server` ne plante pas, l'empreinte mémoire est limitée et les performances ne se dégradent pas au fil du temps. - -Les délais précis d'exécution des requêtes ne sont pas enregistrés et ne sont pas comparés en raison de la grande variabilité des requêtes et de l'environnement. - -## Essais De Construction {#build-tests} - -Les tests de construction permettent de vérifier que la construction n'est pas interrompue sur diverses configurations alternatives et sur certains systèmes étrangers. Les Tests sont situés à `ci` répertoire. Ils exécutent build from source à L'intérieur de Docker, Vagrant, et parfois avec `qemu-user-static` à l'intérieur de Docker. Ces tests sont en cours de développement et les essais ne sont pas automatisées. - -Motivation: - -Normalement, nous libérons et exécutons tous les tests sur une seule variante de construction ClickHouse. Mais il existe des variantes de construction alternatives qui ne sont pas complètement testées. Exemple: - -- construire sur FreeBSD; -- construire sur Debian avec les bibliothèques des paquets système; -- construire avec des liens partagés de bibliothèques; -- construire sur la plate-forme AArch64; -- construire sur la plate-forme PowerPc. - -Par exemple, construire avec des paquets système est une mauvaise pratique, car nous ne pouvons pas garantir quelle version exacte des paquets un système aura. Mais c'est vraiment nécessaire pour les responsables Debian. Pour cette raison, nous devons au moins soutenir cette variante de construction. Un autre exemple: la liaison partagée est une source commune de problèmes, mais elle est nécessaire pour certains amateurs. - -Bien que nous ne puissions pas exécuter tous les tests sur toutes les variantes de builds, nous voulons vérifier au moins que les différentes variantes de build ne sont pas cassées. Pour cela nous utilisons les essais de construction. - -## Test de compatibilité du protocole {#testing-for-protocol-compatibility} - -Lorsque nous étendons le protocole réseau ClickHouse, nous testons manuellement que l'ancien clickhouse-client fonctionne avec le nouveau clickhouse-server et que le nouveau clickhouse-client fonctionne avec l'ancien clickhouse-server (simplement en exécutant des binaires à partir des paquets correspondants). - -## L'aide du Compilateur {#help-from-the-compiler} - -Code ClickHouse principal (qui est situé dans `dbms` annuaire) est construit avec `-Wall -Wextra -Werror` et avec quelques avertissements supplémentaires activés. Bien que ces options ne soient pas activées pour les bibliothèques tierces. - -Clang a des avertissements encore plus utiles - vous pouvez les chercher avec `-Weverything` et choisissez quelque chose à construire par défaut. - -Pour les builds de production, gcc est utilisé (il génère toujours un code légèrement plus efficace que clang). Pour le développement, clang est généralement plus pratique à utiliser. Vous pouvez construire sur votre propre machine avec le mode débogage (pour économiser la batterie de votre ordinateur portable), mais veuillez noter que le compilateur est capable de générer plus d'Avertissements avec `-O3` grâce à une meilleure analyse du flux de contrôle et de l'inter-procédure. Lors de la construction avec clang avec le mode débogage, la version de débogage de `libc++` est utilisé qui permet d'attraper plus d'erreurs à l'exécution. - -## Désinfectant {#sanitizers} - -**Désinfectant d'adresse**. -Nous exécutons des tests fonctionnels et d'intégration sous ASan sur la base de per-commit. - -**Valgrind (Memcheck)**. -Nous effectuons des tests fonctionnels sous Valgrind pendant la nuit. Cela prend plusieurs heures. Actuellement il y a un faux positif connu dans `re2` bibliothèque, consultez [cet article](https://research.swtch.com/sparse). - -**Désinfectant de comportement indéfini.** -Nous exécutons des tests fonctionnels et d'intégration sous ASan sur la base de per-commit. - -**Désinfectant pour filetage**. -Nous exécutons des tests fonctionnels sous TSan sur la base de per-commit. Nous n'exécutons toujours pas de tests D'intégration sous TSan sur la base de la validation. - -**Mémoire de désinfectant**. -Actuellement, nous n'utilisons toujours pas MSan. - -**Débogueur allocateur.** -Version de débogage de `jemalloc` est utilisé pour la construction de débogage. - -## Fuzzing {#fuzzing} - -Clickhouse fuzzing est implémenté à la fois en utilisant [libFuzzer](https://llvm.org/docs/LibFuzzer.html) et des requêtes SQL aléatoires. -Tous les tests de fuzz doivent être effectués avec des désinfectants (adresse et indéfini). - -LibFuzzer est utilisé pour les tests de fuzz isolés du code de la bibliothèque. Les Fuzzers sont implémentés dans le cadre du code de test et ont “_fuzzer” nom postfixes. -Exemple Fuzzer peut être trouvé à `src/Parsers/tests/lexer_fuzzer.cpp`. Les configs, dictionnaires et corpus spécifiques à LibFuzzer sont stockés à `tests/fuzz`. -Nous vous encourageons à écrire des tests fuzz pour chaque fonctionnalité qui gère l'entrée de l'utilisateur. - -Fuzzers ne sont pas construits par défaut. Pour construire fuzzers à la fois `-DENABLE_FUZZING=1` et `-DENABLE_TESTS=1` options doivent être définies. -Nous vous recommandons de désactiver Jemalloc lors de la construction de fuzzers. Configuration utilisée pour intégrer clickhouse fuzzing à -Google OSS-Fuzz peut être trouvé à `docker/fuzz`. - -Nous utilisons également un simple test fuzz pour générer des requêtes SQL aléatoires et vérifier que le serveur ne meurt pas en les exécutant. -Vous pouvez le trouver dans `00746_sql_fuzzy.pl`. Ce test doit être exécuté en continu (pendant la nuit et plus longtemps). - -## Audit De Sécurité {#security-audit} - -Les gens de L'équipe de sécurité Yandex font un aperçu de base des capacités de ClickHouse du point de vue de la sécurité. - -## Analyseurs Statiques {#static-analyzers} - -Nous courons `PVS-Studio` par commettre base. Nous avons évalué `clang-tidy`, `Coverity`, `cppcheck`, `PVS-Studio`, `tscancode`. Vous trouverez des instructions pour l'utilisation dans `tests/instructions/` répertoire. Aussi, vous pouvez lire [l'article en russe](https://habr.com/company/yandex/blog/342018/). - -Si vous utilisez `CLion` en tant QU'IDE, vous pouvez tirer parti de certains `clang-tidy` contrôles de la boîte. - -## Durcir {#hardening} - -`FORTIFY_SOURCE` est utilisé par défaut. C'est presque inutile, mais cela a toujours du sens dans de rares cas et nous ne le désactivons pas. - -## Code De Style {#code-style} - -Les règles de style de Code sont décrites [ici](https://clickhouse.tech/docs/en/development/style/). - -Pour vérifier certaines violations de style courantes, vous pouvez utiliser `utils/check-style` script. - -Pour forcer le style approprié de votre code, vous pouvez utiliser `clang-format`. Fichier `.clang-format` est situé à la racine des sources. Il correspond principalement à notre style de code réel. Mais il n'est pas recommandé d'appliquer `clang-format` pour les fichiers existants, car il rend le formatage pire.

Örneğin, için `Lexer` bir araç var `src/Parsers/tests/lexer` bu sadece stdin'in tokenizasyonunu yapar ve renklendirilmiş sonucu stdout'a yazar. Bu tür araçları kod örnekleri olarak ve keşif ve manuel test için kullanabilirsiniz. - -Ayrıca Çift Dosya yerleştirebilirsiniz `.sh` ve `.reference` aracı ile birlikte bazı önceden tanımlanmış giriş üzerinde çalıştırmak için-daha sonra komut sonucu karşılaştırılabilir `.reference` Dosya. Bu tür testler otomatik değildir. - -## Çeşitli Testler {#miscellaneous-tests} - -Bulunan dış sözlükler için testler vardır `tests/external_dictionaries` ve makine öğrenilen modeller için `tests/external_models`. Bu testler güncelleştirilmez ve tümleştirme testlerine aktarılmalıdır. - -Çekirdek ekler için ayrı bir test var. Bu test, ayrı sunucularda ClickHouse kümesini çalıştırır ve çeşitli arıza durumlarını taklit eder: ağ bölünmesi, paket bırakma (ClickHouse düğümleri arasında, ClickHouse ve ZooKeeper arasında, ClickHouse sunucusu ve istemci arasında, vb.), `kill -9`, `kill -STOP` ve `kill -CONT` , istemek [Jepsen](https://aphyr.com/tags/Jepsen). Daha sonra test, kabul edilen tüm eklerin yazıldığını ve reddedilen tüm eklerin olmadığını kontrol eder. - -Clickhouse açık kaynaklı önce çekirdek testi ayrı ekip tarafından yazılmıştır. Bu takım artık ClickHouse ile çalışmıyor. Test yanlışlıkla Java ile yazılmıştır. Bu nedenlerden dolayı, çekirdek testi yeniden yazılmalı ve entegrasyon testlerine taşınmalıdır. - -## Manuel Test {#manual-testing} - -Yeni bir özellik geliştirdiğinizde, el ile de test etmek mantıklıdır. Bunu aşağıdaki adımlarla yapabilirsiniz: - -ClickHouse Oluşturun. Terminalden Clickhouse'u çalıştırın: dizini değiştir `programs/clickhouse-server` ve ile çalıştırın `./clickhouse-server`. Bu yapılandırma kullanacak (`config.xml`, `users.xml` ve içindeki dosyalar `config.d` ve `users.d` dizinler) geçerli dizinden varsayılan olarak. ClickHouse sunucusuna bağlanmak için, çalıştırın `programs/clickhouse-client/clickhouse-client`. - -Tüm clickhouse araçlarının (sunucu, istemci, vb.) sadece tek bir ikili için symlinks olduğunu unutmayın `clickhouse`. Bu ikili bulabilirsiniz `programs/clickhouse`.

-## 功能性测试 {#gong-neng-xing-ce-shi} - -功能性测试是最简便使用的。绝大部分 ClickHouse 的功能可以通过功能性测试来测试，任何代码的更改都必须通过该测试。 - -每个功能测试会向正在运行的 ClickHouse服务器发送一个或多个查询，并将结果与预期结果进行比较。 - -测试用例在 `tests/queries` 目录中。这里有两个子目录：`stateless` 和 `stateful`目录。无状态的测试无需预加载测试数据集 - 通常是在测试运行期间动态创建小量的数据集。有状态测试需要来自 Yandex.Metrica 的预加载测试数据，而不向一般公众提供。我们倾向于仅使用«无状态»测试并避免添加新的«有状态»测试。 - -每个测试用例可以是两种类型之一：`.sql` 和 `.sh`。`.sql` 测试文件是用于管理`clickhouse-client --multiquery --testmode`的简单SQL脚本。`.sh` 测试文件是一个可以自己运行的脚本。 - -要运行所有测试，请使用 `tests/clickhouse-test` 工具，用 `--help` 可以获取所有的选项列表。您可以简单地运行所有测试或运行测试名称中的子字符串过滤的测试子集：`./clickhouse-test substring`。 - -调用功能测试最简单的方法是将 `clickhouse-client` 复制到`/usr/bin/`，运行`clickhouse-server`，然后从自己的目录运行`./ clickhouse-test`。 - -要添加新测试，请在 `tests/queries/0_stateless` 目录内添加新的 `.sql` 或 `.sh` 文件，手动检查，然后按以下方式生成 `.reference` 文件： `clickhouse-client -n --testmode < 00000_test.sql > 00000_test.reference` 或 `./00000_test.sh > ./00000_test.reference`。 - -测试应该只使用（创建，删除等）`test` 数据库中的表，这些表假定是事先创建的; 测试也可以使用临时表。 - -如果要在功能测试中使用分布式查询，可以利用 `remote` 表函数和 `127.0.0.{1..2}` 地址为服务器查询自身; 或者您可以在服务器配置文件中使用预定义的测试集群，例如`test_shard_localhost`。 - -有些测试在名称中标有 `zookeeper`，`shard` 或 `long`。`zookeeper` 用于使用ZooKeeper的测试; `shard` 用于需要服务器监听`127.0.0.*`的测试。`long` 适用于运行时间稍长一秒的测试。 - -## 已知的bug {#yi-zhi-de-bug} - -如果我们知道一些可以通过功能测试轻松复制的错误，我们将准备好的功能测试放在 `tests/queries/bugs` 目录中。当修复错误时，这些测试将被移动到 `tests/queries/0_stateless` 目录中。 - -## 集成测试 {#ji-cheng-ce-shi} - -集成测试允许在集群配置中测试 ClickHouse，并与其他服务器（如MySQL，Postgres，MongoDB）进行 ClickHouse 交互。它们可用于模拟网络拆分，数据包丢弃等。这些测试在Docker下运行，并使用各种软件创建多个容器。 - -参考 `tests/integration/README.md` 文档关于如何使用集成测试。 - -请注意，ClickHouse 与第三方驱动程序的集成未经过测试。此外，我们目前还没有与 JDBC 和ODBC 驱动程序进行集成测试。 - -## 单元测试 {#dan-yuan-ce-shi} - -当您想要测试整个 ClickHouse，而不是单个独立的库或类时，单元测试非常有用。您可以使用`ENABLE_TESTS` CMake 选项启用或禁用测试构建。单元测试（和其他测试程序）位于代码中的`tests` 子目录中。要运行单元测试，请键入 `ninja test`。有些测试使用 `gtest`，但有些只是在测试失败时返回非零状态码。 - -如果代码已经被功能测试覆盖（并且功能测试通常使用起来要简单得多），则不一定要进行单元测试。 - -## 性能测试 {#xing-neng-ce-shi} - -性能测试允许测量和比较综合查询中 ClickHouse 的某些独立部分的性能。测试位于`tests/performance` 目录中。每个测试都由 `.xml` 文件表示，并附有测试用例的描述。使用 `clickhouse performance-test` 工具（嵌入在 `clickhouse` 二进制文件中）运行测试。请参阅 `--help` 以进行调用。 - -每个测试在循环中运行一个或多个查询（可能带有参数组合），并具有一些停止条件（如«最大执行速度不会在三秒内更改»）并测量一些有关查询性能的指标（如«最大执行速度»））。某些测试可以包含预加载的测试数据集的前提条件。 - -如果要在某些情况下提高 ClickHouse 的性能，并且如果可以在简单查询上观察到改进，则强烈建议编写性能测试。在测试过程中使用 `perf top` 或其他 perf 工具总是有意义的。 - -性能测试不是基于每个提交运行的。不收集性能测试结果，我们手动比较它们。 - -## 测试工具和脚本 {#ce-shi-gong-ju-he-jiao-ben} - -`tests`目录中的一些程序不是准备测试，而是测试工具。例如，对于`Lexer`，有一个工具`src/Parsers/tests/lexer` 标准输出。您可以使用这些工具作为代码示例以及探索和手动测试。 - -您还可以将一对文件 `.sh` 和 `.reference` 与工具放在一些预定义的输入上运行它 - 然后可以将脚本结果与 `.reference` 文件进行比较。这些测试不是自动化的。 - -## 杂项测试 {#za-xiang-ce-shi} - -有一些外部字典的测试位于 `tests/external_dictionaries`，机器学习模型在`tests/external_models`目录。这些测试未更新，必须转移到集成测试。 - -对于分布式数据的插入，有单独的测试。此测试在单独的服务器上运行 ClickHouse 集群并模拟各种故障情况：网络拆分，数据包丢弃（ClickHouse 节点之间，ClickHouse 和 ZooKeeper之间，ClickHouse 服务器和客户端之间等），进行 `kill -9`，`kill -STOP` 和`kill -CONT` 等操作，类似[Jepsen](https://aphyr.com/tags/Jepsen)。然后，测试检查是否已写入所有已确认的插入，并且所有已拒绝的插入都未写入。 - -在 ClickHouse 开源之前，分布式测试是由单独的团队编写的，但该团队不再使用 ClickHouse，测试是在 Java 中意外编写的。由于这些原因，必须重写分布式测试并将其移至集成测试。 - -## 手动测试 {#shou-dong-ce-shi} - -当您开发了新的功能，做手动测试也是合理的。可以按照以下步骤来进行： - -编译 ClickHouse。在命令行中运行 ClickHouse：进入 `programs/clickhouse-server` 目录并运行 `./clickhouse-server`。它会默认使用当前目录的配置文件 (`config.xml`， `users.xml` 以及在 `config.d` 和 `users.d` 目录的文件)。可以使用 `programs/clickhouse-client/clickhouse-client` 来连接数据库。 - -或者，您可以安装 ClickHouse 软件包：从 Yandex 存储库中获得稳定版本，或者您可以在ClickHouse源根目录中使用 `./release` 构建自己的软件包。然后使用 `sudo service clickhouse-server start` 启动服务器（或停止服务器）。在 `/etc/clickhouse-server/clickhouse-server.log` 中查找日志。 - -当您的系统上已经安装了 ClickHouse 时，您可以构建一个新的 `clickhouse` 二进制文件并替换现有的二进制文件： - - sudo service clickhouse-server stop - sudo cp ./clickhouse /usr/bin/ - sudo service clickhouse-server start - -您也可以停止 clickhouse-server 并使用相同的配置运行您自己的服务器，日志打印到终端： - - sudo service clickhouse-server stop - sudo -u clickhouse /usr/bin/clickhouse server --config-file /etc/clickhouse-server/config.xml - -使用 gdb 的一个示例: - - sudo -u clickhouse gdb --args /usr/bin/clickhouse server --config-file /etc/clickhouse-server/config.xml - -如果 clickhouse-server 已经运行并且您不想停止它，您可以更改 `config.xml` 中的端口号（或在 `config.d` 目录中的文件中覆盖它们），配置适当的数据路径，然后运行它。 - -`clickhouse` 二进制文件几乎没有依赖关系，适用于各种 Linux 发行版。要快速地测试服务器上的更改，您可以简单地将新建的 `clickhouse` 二进制文件 `scp` 到其他服务器，然后按照上面的示例运行它。 - -## 测试环境 {#ce-shi-huan-jing} - -在将版本发布为稳定之前，我们将其部署在测试环境中测试环境是一个处理\[Yandex.Metrica\]（https://metrica.yandex.com/）总数据的1/39部分大小的集群。我们与 Yandex.Metrica 团队公用我们的测试环境。ClickHouse 在现有数据的基础上无需停机即可升级。我们首先看到数据处理成功而不会实时滞后，复制继续工作，并且 Yandex.Metrica 团队无法看到问题。首先的检查可以通过以下方式完成： - - SELECT hostName() AS h, any(version()), any(uptime()), max(UTCEventTime), count() FROM remote('example01-01-{1..3}t', merge, hits) WHERE EventDate >= today() - 2 GROUP BY h ORDER BY h; - -在某些情况下，我们还部署到 Yandex 的合作团队的测试环境：市场，云等。此外，我们还有一些用于开发目的的硬件服务器。 - -## 负载测试 {#fu-zai-ce-shi} - -部署到测试环境后，我们使用生产群集中的查询运行负载测试。这是手动完成的。 - -确保在生产集群中开启了 `query_log` 选项。 - -收集一天或更多的查询日志： - - clickhouse-client --query="SELECT DISTINCT query FROM system.query_log WHERE event_date = today() AND query LIKE '%ym:%' AND query NOT LIKE '%system.query_log%' AND type = 2 AND is_initial_query" > queries.tsv - -这是一个复杂的例子。`type = 2` 将过滤成功执行的查询。`query LIKE'％ym：％'` 用于从 Yandex.Metrica 中选择相关查询。`is_initial_query` 是仅选择由客户端发起的查询，而不是由 ClickHouse 本身（作为分布式查询处理的一部分）。 - -`scp` 这份日志到测试机器，并运行以下操作： - - clickhouse benchmark --concurrency 16 < queries.tsv - -(可能你需要指定运行的用户 `--user`) - -然后离开它一晚或周末休息一下。 - -你要检查下 `clickhouse-server` 是否崩溃，内存占用是否合理，性能也不会随着时间的推移而降低。 - -由于查询和环境的高度可变性，不会记录精确的查询执行时序并且不进行比较。 - -## 编译测试 {#bian-yi-ce-shi} - -构建测试允许检查构建在各种替代配置和某些外部系统上是否被破坏。测试位于`ci`目录。它们从 Docker，Vagrant 中的源代码运行构建，有时在 Docker 中运行 `qemu-user-static`。这些测试正在开发中，测试运行不是自动化的。 - -动机： - -通常我们会在 ClickHouse 构建的单个版本上发布并运行所有测试。但是有一些未经过彻底测试的替代构建版本。例子： - -- 在 FreeBSD 中的构建； -- 在 Debian 中使用系统包中的库进行构建； -- 使用库的共享链接构建； -- 在 AArch64 平台进行构建。 - -例如，使用系统包构建是不好的做法，因为我们无法保证系统具有的确切版本的软件包。但 Debian 维护者确实需要这样做。出于这个原因，我们至少必须支持这种构建。另一个例子：共享链接是一个常见的麻烦来源，但是对于一些爱好者来说需要它。 - -虽然我们无法对所有构建版本运行所有测试，但我们想要检查至少不会破坏各种构建变体。为此，我们使用构建测试。 - -## 测试协议兼容性 {#ce-shi-xie-yi-jian-rong-xing} - -当我们扩展 ClickHouse 网络协议时，我们手动测试旧的 clickhouse-client 与新的 clickhouse-server 和新的clickhouse-client 一起使用旧的 clickhouse-server (只需从相应的包中运行二进制文件) - -## 来自编译器的提示 {#lai-zi-bian-yi-qi-de-ti-shi} - -ClickHouse 主要的代码 (位于`dbms`目录中) 使用 `-Wall -Wextra -Werror` 构建，并带有一些其他已启用的警告。 虽然没有为第三方库启用这些选项。 - -Clang 有更多有用的警告 - 您可以使用 `-Weverything` 查找它们并选择默认构建的东西。 - -对于生产构建，使用 gcc（它仍然生成比 clang 稍高效的代码）。对于开发来说，clang 通常更方便使用。您可以使用调试模式在自己的机器上构建（以节省笔记本电脑的电量），但请注意，由于更好的控制流程和过程分析，编译器使用 `-O3` 会生成更多警告。 当使用 clang 构建时，使用 `libc++` 而不是 `libstdc++`，并且在使用调试模式构建时，使用调试版本的 `libc++`，它允许在运行时捕获更多错误。 - -## Sanitizers {#sanitizers} - -### Address sanitizer -我们使用Asan对每个提交进行功能和集成测试。 - -### Valgrind (Memcheck) -我们在夜间使用Valgrind进行功能测试。这需要几个小时。目前在 `re2` 库中有一个已知的误报，请参阅[文章](https://research.swtch.com/sparse)。 - -### Undefined behaviour sanitizer -我们使用Asan对每个提交进行功能和集成测试。 - -### Thread sanitizer -我们使用TSan对每个提交进行功能测试。目前不使用TSan对每个提交进行集成测试。 - -### Memory sanitizer -目前我们不使用 MSan。 - -### Debug allocator -您可以使用 `DEBUG_TCMALLOC` CMake 选项启用 `tcmalloc` 的调试版本。我们在每次提交的基础上使用调试分配器运行测试。 - -更多请参阅 `tests/instructions/sanitizers.txt`。 - -## 模糊测试 {#mo-hu-ce-shi} - -ClickHouse模糊测试可以通过[libFuzzer](https://llvm.org/docs/LibFuzzer.html)和随机SQL查询实现。 -所有的模糊测试都应使用sanitizers（Address及Undefined）。 - -LibFuzzer用于对库代码进行独立的模糊测试。模糊器作为测试代码的一部分实现，并具有“_fuzzer”名称后缀。 -模糊测试示例在`src/Parsers/tests/lexer_fuzzer.cpp`。LibFuzzer配置、字典及语料库存放在`tests/fuzz`。 -我们鼓励您为每个处理用户输入的功能编写模糊测试。 - -默认情况下不构建模糊器。可通过设置`-DENABLE_FUZZING=1`和`-DENABLE_TESTS=1`来构建模糊器。 我们建议在构建模糊器时关闭Jemalloc。 -用于将ClickHouse模糊测试集成到的Google OSS-Fuzz的配置文件位于`docker/fuzz`。 - -此外，我们使用简单的模糊测试来生成随机SQL查询并检查服务器是否正常。你可以在`00746_sql_fuzzy.pl` 找到它。测试应连续进行（过夜和更长时间）。 - -## 安全审计 {#an-quan-shen-ji} - -Yandex Cloud 部门的人员从安全角度对 ClickHouse 功能进行了一些基本概述。 - -## 静态分析 {#jing-tai-fen-xi} - -我们偶尔使用静态分析。我们已经评估过 `clang-tidy`， `Coverity`， `cppcheck`， `PVS-Studio`， `tscancode`。您将在 `tests/instructions/` 目录中找到使用说明。你也可以阅读[俄文文章](https://habr.com/company/yandex/blog/342018/). - -如果您使用 `CLion` 作为 IDE，您可以开箱即用一些 `clang-tidy` 检查。 - -## 其他强化 {#qi-ta-qiang-hua} - -默认情况下使用 `FORTIFY_SOURCE`。它几乎没用，但在极少数情况下仍然有意义，我们不会禁用它。 - -## 代码风格 {#dai-ma-feng-ge} - -代码风格在[这里](https://clickhouse.tech/docs/en/development/style/) 有说明。 - -要检查一些常见的样式冲突，您可以使用 `utils/check-style` 脚本。 - -为了强制你的代码的正确风格，你可以使用 `clang-format` 文件。`.clang-format` 位于源代码根目录， 它主要与我们的实际代码风格对应。但不建议将 `clang-format` 应用于现有文件，因为它会使格式变得更糟。您可以使用 `clang-format-diff` 工具，您可以在 clang 源代码库中找到 - -或者，您可以尝试`uncrustify` 工具来格式化您的代码。配置文件在源代码的根目录中的`uncrustify.cfg`。它比 `clang-format` 经过更少的测试。 - -`CLion` 有自己的代码格式化程序，必须调整为我们的代码风格。 - -## Metrica B2B 测试 {#metrica-b2b-ce-shi} - -每个 ClickHouse 版本都经过 Yandex Metrica 和 AppMetrica 引擎的测试。测试和稳定版本的 ClickHouse 部署在虚拟机上，并使用处理输入数据固定样本的度量引擎的小副本运行。将度量引擎的两个实例的结果一起进行比较 - -这些测试是由单独的团队自动完成的。由于移动部件的数量很多，大部分时间的测试都是完全无关的，很难弄清楚。很可能这些测试对我们来说是负值。然而，这些测试被证明是有用的大约一个或两个倍的数百。 - -## 测试覆盖率 {#ce-shi-fu-gai-lu} - -截至2018年7月，我们不会跟踪测试复盖率。 - -## 自动化测试 {#zi-dong-hua-ce-shi} - -我们使用 Yandex 内部 CI 和名为«沙箱»的作业自动化系统运行测试。我们还继续使用 Jenkins（可在Yandex内部使用）。 - -构建作业和测试在沙箱中按每次提交的基础上运行。结果包和测试结果发布在 GitHub 上，可以通过直接链接下载，结果会被永久存储。当您在 GitHub 上发送拉取请求时，我们将其标记为«可以测试»，我们的 CI 系统将为您构建 ClickHouse 包（发布，调试，地址消除等）。 - -由于时间和计算能力的限制，我们不使用 Travis CI。 - -在 Jenkins，我们运行字典测试，指标B2B测试。我们使用 Jenkins 来准备和发布版本。Jenkins是一种传统的技术，所有的工作将被转移到沙箱中。 -

Some tests can contain preconditions on preloaded test dataset. If you want to improve performance of ClickHouse in some scenario, and if improvements can be observed on simple queries, it is highly recommended to write a performance test. It always makes sense to use `perf top` or other perf tools during your tests.
