jvm-sandbox's Issues
[问题]sandbox server是和目标进程公用一个JVM？
简单的了解了下启动部分，看到jetty的启动是在AgentLauncher里进行的，所以最后外部访问的server是放在目标的JVM里吗？如果是这样，这么做的考量是什么呢？为什么不单独放在外部呢？
如果有理解错的地方，望指正。
自研模块如何添加第三方依赖jar
看例子里面的maven文件只添加了sandbox和servlet-api的provide依赖，如果想添加一些compile的依赖jar怎么打包模块，是用jarjar么？ 还是能有一个classpath的位置放这些第三方的包？
jvm-sandbox是否支持打成jar包，类似第三方依赖的方式引入项目
现在项目希望全部推行sandbox，有全部的demo样例吗，demo只要线上故障模拟？？
线上故障定位
线上系统流控
线上故障模拟
方法请求录制和结果回放
动态日志打印
安全信息监测和脱敏
行链路计算和覆盖率统计
执行-R命令时sandbox.log会有异常抛出
虽然不影响功能，但毕竟不优雅，需要再下次发布时解决

可以attach远程JVM吗
你好，我想用sandbox客户端在本地操作多台远程服务器上的JVM，可以吗？
Windows 无法启动解决
AgentLauncher.java#L24
小改一下就OK了, 原因.getCodeSource().getLocation()返回的URl,路径分隔符一定是/,用File.separator去substring自然在Win下会出问题
SANDBOX_HOME
= substringBeforeLast(AgentLauncher.class.getProtectionDomain().getCodeSource().getLocation().getFile(), File.separator)
+ File.separator + "..";
SANDBOX_HOME = new File(AgentLauncher.class.getProtectionDomain().getCodeSource().getLocation().getFile()).getParentFile().getParent();增强的类出现循环依赖错误

想问一下怎么访问被观测方法的入参？
问题：
想观察一下系统所有的对外发起HTTP的requestBody (基于Apache HTTPClient)，记录到log文件。
@Override
public CloseableHttpResponse execute(
final HttpUriRequest request,
final HttpContext context) throws IOException, ClientProtocolException
在观察的事件里面需要调用request.getURI()之类的方法
这里的HttpUriRequest, HttpContext, CloseableHttpResponse 类在应用系统里面（Tomcat）均是被WebappClassLoader载入的， 在沙箱的模块代码里面如何访问这些应用的Class的？
我看了下沙箱项目的ClassLoader的设计和Class的隔离的管理，下面是我的理解，不知道是否有误：
- 沙箱项目的Spy类在最顶级的BootstrapClassLoader被加载
- 被观察的系统的类按照其自己的设计和部署（比如Tomcat）, 用合适的ClassLoader载入自己相关目录资源下面的class.
- 沙箱模块自己的Class由沙箱自己的SandboxClassLoader载入，包括用户使用的EventWatcher
4.在被观察模块里面注入对Spy类的调用(触发调用用户提供的Handler)
用户在自己的handler里面怎么才能访问到入参的Class呢？这里是要用ContextClassLoader来反射调用吗？
不支持JDK9
jvm-sandbox容器在JDK9运行的时候会报错，需要对
- asm5.0太老了，需要升级到6.0
- 找不到
javax.annotation.Resource类
SANDBOX提供感知业务容器的HOOK
在很多场景中需要拿到目标对象的实例，而SANDBOX的框架机制是不允许你能拿到对象实例的。所以需要提供一个HOOK，侵入到业务代码中拿到这个实例。
需求：SANDBOX需要提供一个hook-api系列，以便与大家能通过SANDBOX容器通过这个HOOK拿到目标对象的实例
自定义module中的日志会输出到哪里呢？
哪里都找不到诶
有spring boot引入的例子么？
是否可以通过starter的方式接入呢？提供的手册，也不是了解具体要怎么操作。
启动时报这个错误，但jar包里肯定有这个类的。

希望@Http标签支持通配符匹配
目前在jvm-sandbox中
@Http("/greys/*")这种HTTP匹配的通配符写法不被支持，希望能支持下，给module实现更多的灵活空间
为什么安装完成没有用户模块${HOME}/.sandbox-module/
安装完成后再在${HOME}/.sandbox-module/ 没有这个目录

clock用例没有执行
attach之后得到：
./sandbox.sh -p 48630 -F

这个是什么意思呢？已经把package结果复制到 ~/.sandbox-module/下面了；attach也能attach成功，但是看不到active的module？
SandboxClassLoader的parent为AppClassLoader导致的logback加载问题

SLF4J: Actual binding is of type [ch.qos.logback.classic.util.ContextSelectorStaticBinder]当应用AppClassLoader中有logback时，sandbox启动时，会在应用的控制台日志中输出如上的信息，原因是SandboxClassLoader的parent为AppClassLoader，Slf4j在初始化时会扫描classpath下的实现类，这时会加载到应用中的资源；
建议是将SandboxClassLoader的parent设置为ext classloader。
用例过少
JVM Sandbox现在的用例非常少,可否供一些典型场景的用例供学习使用。这样子也方便项目推广。

sandbox-stable-bin.zip下载超时
想在现在的项目引入sandbox，在下载bin的时候报超时。
call before 为何对调用两次？
moduleEventWatcher.watch(
// 匹配到Clock$BrokenClock#checkState()
new NameRegexFilter("TestLambda", "main1"),
// 监听THROWS事件并且改变原有方法抛出异常为正常返回
new EventListener() {
@Override
public void onEvent(Event event) throws Throwable {
// 立即返回
System.out.println("aaaaaaaaaaaaaaaaaaaaaa");
}
},
// 指定监听的事件为抛出异常
Event.Type.CALL_BEFORE
把例子稍微修改了一下，为何调用一次main1之前会调用两次这个call before的内容，有遇到过的吗
方法功能增强问题
希望在支持Spring框架的情况下，能够进一步改进方法的增强方式，比如一个方法原来没有抛出异常，我现在改为让它抛出异常的话，我还需要同时加上@transactional注解事务，让它开启事务，以验证一些问题，这方面的功能增强仍然有提升空间。还有一个应用场景：
我写了一段代码，想要在指定方法的before之前拦截住，不让它执行原来有问题的代码，而改为执行我现在的代码，那么，一般情况下这段代码，是有很强的针对性的，我写的这段代码竟然能匹配很多类的很多个方法，个人感觉这种情况一般不会发生，真遇到这种情况，最初写工程的时候，我就要把它提取出来做一定的抽象和封装，这样才能减少代码冗余，降低维护成本。所以，正则匹配类名和方法名的这个问题，我觉得还可以再讨论一下。
Provider模块无法正确识别@Resource
在解决#5问题的时候，遗漏修改了ProviderClassLoader，导致实现了sandbox-provider-api的模块使用到了@resource时无法正确被加载

新版“脊柱”发布公告
新版“脊柱”发布公告
同步群主的消息
年后SANDBOX将会发布新版本，代号：脊柱；
核心特性有
-
插桩点增强
-
增加
AspectJ Pointcut expression支持可能会跳票
将会精简实现Aspject的部分表达式语法，以后写埋点的时候将不用那么痛苦去实现Filter，直接拼写表达式即可。表达式可以参考：Spring AOP AspectJ Pointcut Expressions With Examples
-
增加
Wildcard Pointcut expression支持进一步降低类匹配门槛
-
增加对实现类、子类的支持
当前Filter只能过滤普通的Class，但实际在使用过程中往往实现类是匿名内部类或通过工厂模式所生产，无法拿到确定的类。
-
-
API优化
相信各位已经在实现Sandbox-Module的时候被Event的处理折腾疯了，我也看到很多人在写例子的时候会踩到线程安全，递归调用等常见的坑，这些都是API不够友好所导致。
很多人也私聊推荐我们采用bytebuddy的优美API，我们收到了。正在考虑中，希望集思广益～
-
模块消息通讯
开源的最大价值在于给JVM-SANDOBX沉淀更多的模块。但沉淀的模块如果没有被复用的价值，那是不会有人期待公共模块的诞生，没有买卖就没有市场。
最近也在看Pinpoint的代码，里面对我触动最大的就是沉淀了市面上常见的中间件的埋点代码。如何让更多的埋点事件沉淀到JVM-SANDBOX生态圈上，并进一步降低大家的门槛。
我们的解决方案是增加模块之间的消息通讯，敬请期待～
-
增加更多的Example
这个似乎是更多人的呼声了，但你希望增加那些EXAMPLE呢？时间毕竟有限，我可以选择投票最高的2个来实现。
- 线上故障定位
- 线上系统流控
- 线上故障模拟
- 方法请求录制和结果回放
- 动态日志打印
- 安全信息监测和脱敏

provider目录是做什么目的的？
看到Sandbox有两个项目和"provider"相关，好像也是一种用SPI进行插件加载的架构。
${SANDBOX_TARGET_DIR}/provider/sandbox-mgr-provider.jar
但是实现是空的
com.alibaba.jvm.sandbox.provider.mgr.EmptyModuleJarLoadingChain
com.alibaba.jvm.sandbox.provider.mgr.EmptyModuleLoadingChain
另外在DefaultCoreModuleManager里面看到下面这个片段
/**
* 用户模块文件加载回调
*/
final private class InnerModuleJarLoadCallback implements ModuleJarLoader.ModuleJarLoadCallback {
@OverRide
public void onLoad(File moduleJarFile) throws Throwable {
providerManager.loading(moduleJarFile);
}
}
这个是不是说去掉这块也不影响主要功能， 只是说给用户一个口子在每个模块文件加载时候可以有一定的方式可以影响？

沙箱容器版本更新是否需要重启目标应用
如果目标应用已经被植入agent，而此时沙箱容器更新了版本，是不是必须要重启目标JVM才可以使用新版的沙箱容器？
模块加载成功后未生效
按照开发示例中代码进行测试，本地安装成功，attach成功，但是加载模块后，执行./sandbox.sh -p 18083 -d 'broken-clock-tinker/repairCheckState'后未生效。
运行环境：
JDK 1.7
Ubuntu 16.04

遇到的问题
希望支持命名空间
在实际使用过程中，一开始你很难统一大家都用同一个jvm-sandbox来部署、管理所有的moudle。大家都希望能有更多独立的控制权。（容器版本、部署路径、加载策略）
所以希望能支持命名空间，大家通过命名空间隔离。不同命名空间的容器能同时加载且相互之间不会被干扰。
提个建议：用微信群交流是不是更方便呢？
谢谢！
执行.sandbox.sh时报错
安装成功，但是执行./sandbox.sh报错，具体报错信息如下，可能是什么原因了...
SelfCallBarrier#delete(Node node)
节点删除后，虽然没有外部引用它，但它却引用了top节点和next节点，虽然可被回收，但相对gc不友好，
不知道理解的对不对?
为什么安装完成没有用户模块${HOME}/.sandbox-module/
安装完成后再在${HOME}/.sandbox-module/ 没有这个目录
关于 watch 使用时候的一点疑问
我看到文档中只描述了 BEFORE、RETURN、THROWS，但是翻看代码时候发现，com.alibaba.jvm.sandbox.api.event.EVENT 里面有 LINE 事件，请问一下这个有调用实例的 demo 吗，我们可以做到监控某行代码被调用到的情况吗
加载不到jar包，见内容
2018-01-23 07:30:50 INFO module loaded found 1 jar in /root/.sandbox-module
2018-01-23 07:30:50 WARN load sandbox module JAR[file=/root/.sandbox-module/clock-tinker-0.0.1-SNAPSHOT-jar-with-dependencies.jar], but none module loaded, close this ModuleClassLoader.
有同学反馈原声的EventListener很难用
集中在
- 并发场景需要处理
ReturnEvent需要拿到BeforeEvent中的信息需要处理- 各种Event是事件池管控，如若处理不当会引起Event污染的问题
JVM-SANDBOX暴露出EventListener是出于性能上的考虑，所以这个原生的Listener仍然还会留着，只是提供给对性能非常敏感的场景下进行高级使用。
另外将会提供出更多便于使用的封装API给大家
