## 背景信息 | ||
|
||
ElasticJob 已在 GraalVM Native Image 下完成可用性验证。 | ||
|
||
构建包含 `org.apache.shardingsphere.elasticjob:elasticjob-bootstrap:${elasticjob.version}` 的 Maven 依赖的 GraalVM Native Image, | ||
你需要借助于 GraalVM Native Build Tools。 | ||
GraalVM Native Build Tools 提供了 Maven Plugin 和 Gradle Plugin 来简化 GraalVM CE 的 `native-image` 命令行工具的长篇大论的 shell 命令。 | ||
|
||
ElasticJob 要求在如下或更高版本的 `GraalVM CE` 完成构建 GraalVM Native Image。使用者可通过 `SDKMAN!` 快速切换 JDK。这同理 | ||
适用于 https://sdkman.io/jdks#graal , https://sdkman.io/jdks#nik 和 https://sdkman.io/jdks#mandrel 等 `GraalVM CE` 的下游发行版。 | ||
|
||
- GraalVM CE For JDK 22.0.2,对应于 SDKMAN! 的 `22.0.2-graalce` | ||
|
||
用户依然可以使用 SDKMAN! 上的 `21.0.2-graalce` 等旧版本的 GraalVM CE 来构建 ElasticJob 的 GraalVM Native Image 产物。 | ||
ElasticJob 不为已停止维护的 GraalVM CE 版本设置 CI。 | ||
|
||
## 使用 ElasticJob 的 Java API | ||
|
||
### Maven 生态 | ||
|
||
使用者需要主动使用 GraalVM Reachability Metadata 中央仓库。 | ||
如下配置可供参考,以配置项目额外的 Maven Profiles,以 GraalVM Native Build Tools 的文档为准。 | ||
|
||
```xml | ||
<project> | ||
<dependencies> | ||
<dependency> | ||
<groupId>org.apache.shardingsphere.elasticjob</groupId> | ||
<artifactId>elasticjob-bootstrap</artifactId> | ||
<version>${elasticjob.version}</version> | ||
<scope>test</scope> | ||
</dependency> | ||
</dependencies> | ||
|
||
<build> | ||
<plugins> | ||
<plugin> | ||
<groupId>org.graalvm.buildtools</groupId> | ||
<artifactId>native-maven-plugin</artifactId> | ||
<version>0.10.2</version> | ||
<extensions>true</extensions> | ||
<executions> | ||
<execution> | ||
<id>build-native</id> | ||
<goals> | ||
<goal>compile-no-fork</goal> | ||

<phase>package</phase> | ||

<execution> | ||

<goal>test</goal> | ||
</goals> | ||
<phase>test</phase> | ||
</execution> | ||
</executions> | ||
</plugin> | ||
</plugins> | ||
</build> | ||
</project> | ||
``` | ||
|
||
### Gradle 生态 | ||
|
||
使用者需要主动使用 GraalVM Reachability Metadata 中央仓库。 | ||
如下配置可供参考,以配置项目额外的 Gradle Tasks,以 GraalVM Native Build Tools 的文档为准。 | ||
由于 https://github.com/gradle/gradle/issues/17559 的限制,用户需要通过 Maven 依赖的形式引入 Metadata Repository 的 JSON 文件。 | ||
参考 https://github.com/graalvm/native-build-tools/issues/572 。 | ||
|
||
```groovy | ||
plugins { | ||
id 'org.graalvm.buildtools.native' version '0.10.2' | ||
} | ||
dependencies { | ||
implementation 'org.apache.shardingsphere.elasticjob:elasticjob-bootstrap:${elasticjob.version}' | ||
implementation(group: 'org.graalvm.buildtools', name: 'graalvm-reachability-metadata', version: '0.10.2', classifier: 'repository', ext: 'zip') | ||
} | ||
graalvmNative { | ||
metadataRepository { | ||
enabled.set(false) | ||
} | ||
} | ||
``` | ||
|
||
## 对于 sbt 等不被 GraalVM Native Build Tools 支持的构建工具 | ||
|
||
此类需求需要在 https://github.com/graalvm/native-build-tools 打开额外的 issue 并提供对应构建工具的 Plugin 实现。 | ||
|
||
## 使用限制 | ||
|
||
1. 使用者依然需要在 `src/main/resources/META-INF/native-image` 文件夹或 `src/test/resources/META-INF/native-image` 文件夹配置独立文件的 GraalVM Reachability Metadata。 | ||
使用者可通过 GraalVM Native Build Tools 的 GraalVM Tracing Agent 来快速采集 GraalVM Reachability Metadata。 | ||
|
||
2. 对于在 Linux 系统下执行 `elasticJobType` 为 `SCRIPT` 的 `org.apache.shardingsphere.elasticjob.bootstrap.type.ScheduleJobBootstrap`, | ||
若 `script.command.line` 设置为构建 GraalVM Native Image 时, 私有项目的 classpath 下的某个 `.sh` 文件在 GraalVM Native Image 下的相对路径, | ||
则此 `.sh` 文件至少提前设置 `rwxr-xr-x` 的 POSIX 文件权限。 | ||
因为 `com.oracle.svm.core.jdk.resources.NativeImageResourceFileSystem` 显然不支持 `java.nio.file.attribute.PosixFileAttributeView`。 | ||
|
||
3. ElasticJob 的 Spring 命名空间集成模块 `org.apache.shardingsphere.elasticjob:elasticjob-spring-namespace` 尚未在 GraalVM Native Image 下可用。 | ||
|
||
4. ElasticJob 的 Spring Boot Starter 集成模块 `org.apache.shardingsphere.elasticjob:elasticjob-spring-boot-starter` 尚未在 GraalVM Native Image 下可用。 | ||
|
||
## 贡献 GraalVM Reachability Metadata | ||
|
||
ElasticJob 对在 GraalVM Native Image 下的可用性的验证,是通过 GraalVM Native Build Tools 的 Maven Plugin 子项目来完成的。 | ||
通过在 JVM 下运行单元测试,为单元测试打上 `junit-platform-unique-ids*` 标签,此后构建为 GraalVM Native Image 进行 nativeTest 来测试 | ||
在 GraalVM Native Image 下的单元测试覆盖率。请贡献者不要使用 `io.kotest:kotest-runner-junit5-jvm:5.5.4` 等在 `test listener` mode 下 | ||
failed to discover tests 的测试库。 | ||
|
||
ElasticJob 定义了 `elasticjob-test-native` 的 Maven Module 用于为 native Test 提供小型的单元测试子集, | ||
此单元测试子集避免了使用 Mockito 等 native Test 下无法使用的第三方库。 | ||
|
||
ElasticJob 定义了 `nativeTestInElasticJob` 的 Maven Profile 用于为 `elasticjob-test-native` 模块执行 nativeTest 。 | ||
|
||
假设贡献者处于新的 Ubuntu 22.04.4 LTS 实例下,其可通过如下 bash 命令通过 SDKMAN! 管理 JDK 和工具链, | ||
并为 `elasticjob-test-native` 子模块执行 nativeTest。 | ||
|
||
贡献者必须安装 Docker Engine 以执行 `testcontainers-java` 相关的单元测试。 | ||
|
||
```bash | ||
sudo apt install unzip zip curl sed -y | ||
curl -s "https://get.sdkman.io" | bash | ||
source "$HOME/.sdkman/bin/sdkman-init.sh" | ||
sdk install java 22.0.2-graalce | ||
sdk use java 22.0.2-graalce | ||
sudo apt-get install build-essential zlib1g-dev -y | ||
|
||
git clone [email protected]:apache/shardingsphere-elasticjob.git | ||
cd ./shardingsphere-elasticjob/ | ||
./mvnw -PnativeTestInElasticJob -T1C -e clean test | ||
``` | ||
|
||
当贡献者发现缺少与 ElasticJob 无关的第三方库的 GraalVM Reachability Metadata 时,应当在 | ||
https://github.com/oracle/graalvm-reachability-metadata 打开新的 issue, 并提交包含依赖的第三方库缺失的 GraalVM Reachability | ||
Metadata 的 PR。ElasticJob 在 `elasticjob-reachability-metadata` 子模块主动托管了部分第三方库的 GraalVM Reachability Metadata。 | ||
|
||
如果 nativeTest 执行失败, 应为单元测试生成初步的 GraalVM Reachability Metadata, | ||
并手动调整 `elasticjob-reachability-metadata` 子模块的 classpath 的 `META-INF/native-image/org.apache.shardingsphere.elasticjob/elasticjob-reachability-metadata/` 文件夹下的内容以修复 nativeTest。 | ||
如有需要,请使用 `org.junit.jupiter.api.condition.DisabledInNativeImage` 注解或 `org.graalvm.nativeimage.imagecode` 的 | ||
System Property 屏蔽部分单元测试在 GraalVM Native Image 下运行。 | ||
|
||
ElasticJob 定义了 `generateMetadata` 的 Maven Profile 用于在 GraalVM JIT Compiler 下携带 GraalVM Tracing Agent 执行单元测试, | ||
并在 `elasticjob-reachability-metadata` 子模块的 classpath 的 `META-INF/native-image/org.apache.shardingsphere.elasticjob/generated-reachability-metadata/` 文件夹下, | ||
生成或覆盖已有的 GraalVM Reachability Metadata 文件。可通过如下 bash 命令简单处理此流程。 | ||
贡献者仍可能需要手动调整具体的 JSON 条目,并适时调整 Maven Profile 和 GraalVM Tracing Agent 的 Filter 链。 | ||
针对 `elasticjob-reachability-metadata` 子模块, | ||
手动增删改动的 JSON 条目应位于 `META-INF/native-image/org.apache.shardingsphere.elasticjob/elasticjob-reachability-metadata/` 文件夹下, | ||
而 `META-INF/native-image/org.apache.shardingsphere.elasticjob/generated-reachability-metadata/` 中的条目仅应由 `generateMetadata` 的 Maven Profile 生成。 | ||
|
||
以下命令仅为 `elasticjob-test-native` 生成 Conditional 形态的 GraalVM Reachability Metadata 的一个举例。 | ||
生成的 GraalVM Reachability Metadata 位于 `elasticjob-reachability-metadata` 子模块下。 | ||
|
||
对于测试类和测试文件独立使用的 GraalVM Reachability Metadata,贡献者应该放置到 `shardingsphere-test-native` 子模块的 classpath 的 | ||
`META-INF/native-image/elasticjob-test-native-test-metadata/` 下。 | ||
|
||
```bash | ||
git clone [email protected]:apache/shardingsphere.git | ||
cd ./shardingsphere/ | ||
./mvnw -PgenerateMetadata -DskipNativeTests -e -T1C clean test native:metadata-copy | ||
``` |
