- * The DTrace-specific annotations modify the attributes of a DTrace provider - * implementation when it is used by the tracing subsystem. The annotations are - * added to a {@code com.sun.tracing} provider specification to control - * specific attributes of the provider as it relates to DTrace. - *

- * Any other tracing subsystems supported by the system will ignore these - * annotations. - *

- * DTrace probes have additional fields and stability attributes that are - * not accounted for in the generic tracing package. If unspecified, the - * default values are used for the stability and dependency attributes of - * probes, as well as for the module and field names of the generated probes. - * The values can be specified by adding the appropriate annotations to the - * provider specification. - *

- * The {@code FunctionName} annotation is used to annotate the tracepoint - * methods defined in the provider specification. The value of this annotation - * is used as the {@code function} field in the generated DTrace probes. It - * is typically set to the name of the enclosing function where the - * tracepoint is triggered. - *

- * The {@code ModuleName} annotation is used to annotate the provider - * specification itself and applies to all the probes in the provider. It - * sets the value of the {@code module} field in the generated DTrace probes. - *

- * The remaining annotations, are also applied to the provider itself, and - * are used to set the stability and dependency attributes of all probes in - * that provider. Each probe field and the probe arguments can be - * independently assigned interface attributes to control the stability - * ratings of the probes. - *

- * Here is an example of how to declare a provider, specifying additional DTrace - * data: -

-    @ProviderName("my_app_provider")
-    @ModuleName("app.jar")
-    @ProviderAttributes(@Attributes={
-        name=StabilityLevel.STABLE,data=StabilityLevel.STABLE,
-        dependency=DependencyClass.COMMON})
-    @ProbeAttributes(@Attributes={
-        name=StabilityLevel.STABLE,data=StabilityLevel.STABLE,
-        dependency=DependencyClass.COMMON})
-    @ModuleAttributes(@Attributes={name=StabilityLevel.UNSTABLE})
-    public class MyProvider {
-        @FunctionName("main") void startProbe();
-    }

- * To add tracepoints to a program, you must first decide where to place the - * tracepoints, what the logical names are for these points, what information - * will be available to the tracing mechanisms at each point, and decide upon - * any logical grouping. - *

- * You add instrumentation to a program in three steps: - *

    - *
  • First, declare tracepoints by creating interfaces to define - * them, and include these interfaces in the program definition. - * The declared interfaces are standard Java technology-based - * interfaces and are compiled with the program.
    • - *
  • Second, add code in the application to create an instance of the - * interface at some point during the initialization of the application, - * using a factory class provided by the system. The reference to the - * instance can be stored as a global static, or passed as context to all - * the places where it is needed.
    • - *
  • Finally, add the actual tracepoints to the desired locations in the - * application by inserting a call to one of the methods defined in the - * interface, via the factory-created reference.
    • - *
- *

- * The method calls representing the tracepoints have no logical - * impact on the program. The side effect of the call is that any - * activated tracing mechanisms will be notified that the tracepoint has - * been hit, and will take whatever actions are appropriate (for example, - * logging the tracepoint, or triggering a DTrace probe, etc.). In most - * cases, the impact on performance of adding tracepoints to the application - * will be minimal. - *

- * Each logical grouping of tracepoints should be defined in a common - * interface, called a provider. An application can have one or many - * providers. Each provider is independent and can be created whenever - * it is appropriate for that provider, for example, when a subsytem is - * initialized. Providers should be disposed of when they are no longer - * needed, to free up any associated system resources. Each tracepoint - * in a provider is represented by a method in that interface. These methods - * are referred to as probes. The method signature determines the probe - * parameters. A call to the method with the specified parameters triggers - * the probe and makes its parameter values visible to any associated tracing - * mechanism. - *

- * User-defined interfaces which represent providers must extend the - * {@code Provider} interface. To activate the system-defined - * tracing mechanisms, you must obtain an instance of the - * {@code ProviderFactory} class, and pass the class of the provider to - * the {@code createProvider()} method. The returned instance is then used to - * trigger the probes later in the application. - *

- * In addition to triggering the probes, the provider instance can be used - * to obtain direct references to the {@code Probe} objects, which can be used - * directly for triggering, or can be queried to determine whether the probe is - * currently being traced. The {@code Provider} interface also defines a - * {@code Provider.dispose()} method which is used to free up any resources - * that might be associated with that provider. - *

- * When a probe is triggered, any activated tracing system will be given - * the provider name, the probe name, and the values of the probe arguments. - * The tracing system is free to consume this data is whatever way is - * appropriate. - * By default, the provider name is the same as the class name of the interface - * that defines the provider. Similarly, the probe name is - * the name of the method that defines the probe. These default values - * can be over-ridden by annotations. The provider definition can be - * annotated with the {@code @ProviderName} annotation, whose value will - * indicate the provider name that the tracing system will use. Similarly, - * the {@code @ProbeName} annotation annotates a declared method and - * indicates the probe name that should be used in the place of the - * method name. These annotations can be used to define providers and - * probes with the same name, in cases where the semantics of the Java language - * may prevent this. - *

- * Here is a very small and simple usage example: - *

- * -

-   import com.sun.tracing.Provider;
-   import com.sun.tracing.ProviderFactory;
-
-   interface MyProvider extends Provider {
-       void startProbe();
-       void finishProbe(int value);
-   }
-
-   public class MyApplication {
-       public static void main(String argv[]) {
-           ProviderFactory factory = ProviderFactory.getDefaultFactory();
-           MyProvider trace = factory.createProvider(MyProvider.class);
-
-           trace.startProbe();
-           int result = foo();
-           trace.finishProbe(result);
-
-           trace.dispose();
-       }
-   }
-
- *

- * The Java Development Kit (JDK) currently only includes one system-defined - * tracing framework: DTrace. DTrace is enabled automatically whenever an - * application is run on a system and a JDK release that supports it. When - * DTrace is enabled, probes are made available for listing and matching by - * DTrace scripts as soon as the provider is created. At the tracepoint, an - * associated DTrace script is informed of the creation of the provider, and - * it takes whatever action it is designed to take. Tracepoints in the - * program have the following DTrace probe names:
- * {@code :::} - * Where: - *

    - *
  • {@code } the provider name as specified by the application
    • - *
  • {@code } the operating system process ID
    • - *
  • {@code } undefined, unless specified by the application
    • - *
  • {@code } undefined, unless specified by the application
    • - *
  • {@code } the probe name as specified by the application
    • - *
- *

- * The {@code com.sun.tracing.dtrace} package contains additional - * annotations that can be used to control the names used for the - * module and function fields, as well as annotations - * that can be added to the provider to control probe stability and dependency - * attributes. - *

- * Integer, float and string probe parameters are made available to DTrace - * using - * the built-in argument variables, {@code arg0 ... arg_n}. Integer-types - * are passed by value (boxed values are unboxed), floating-point types are - * passed as encoded integer - * arguments, and {@code java.lang.String} objects are converted - * to UTF8 strings, so they can be read into the DTrace script using the - * {@code copyinstr()} intrinsic. Non-string and non-boxed primitive - * reference arguments are only - * placeholders and have no value. - *

- * Using the example above, with a theoretical process ID of 123, these are - * the probes that can be traced from DTrace: -

-    MyProvider123:::startProbe
-    MyProvider123:::finishProbe
-
- * When {@code finishProbe} executes, {@code arg0} will contain the - * value of {@code result}. - *

- * The DTrace tracing mechanism is enabled for all providers, apart from in the - * following circumstances: - *

    - *
  • DTrace is not supported on the underlying system.
    • - *
  • The property {@code com.sun.tracing.dtrace} is set to "disable".
    • - *
  • The RuntimePermission {@code com.sun.tracing.dtrace.createProvider} - * is denied to the process.
    • - *

- * This package also contains the {@code ProviderSkeleton} class, which - * holds most of the common code needed for implementing frameworks. - *

- * The "Null" framework is used when there are no other active frameworks. - * It accomplishes absolutely nothing and is merely a placeholder so that - * the application can call the tracing routines without error. - *

- * The "Multiplex" framework is used when there are multiple active frameworks. - * It is initialized with the framework factories and create providers and - * probes that dispatch to each active framework in turn. - *

- * The "PrintStream" framework is currently a debugging framework which - * dispatches trace calls to a user-defined PrintStream class, defined by - * a property. It may some day be opened up to general use. - *

- * See the {@code sun.tracing.dtrace} and {@code com.sun.tracing.dtrace} - * packages for information on the "DTrace" framework. - */ - -package sun.tracing; diff -r 7f7b6d9e9461 -r 17c1e9d67f71 jdk/src/jdk.runtime/share/native/libjsdt/JVM.c --- a/jdk/src/jdk.runtime/share/native/libjsdt/JVM.c Wed Feb 18 03:45:06 2015 -0800 +++ /dev/null Thu Jan 01 00:00:00 1970 +0000 @@ -1,334 +0,0 @@ -/* - * Copyright (c) 2008, Oracle and/or its affiliates.
