A profiler may be detached from an actively running application by first sealing communications between the application and profiler, then evacuating the profiler by waiting for any profiler-modified or instrumented code to complete execution, profiler runtime code to complete execution, cleaning up any residual items from the profiler, and shutting down the profiler. The profiler may be operational in many different environments, including a managed environment such as a virtual machine and those environments having just in time compiling of executable code.

Detaching profilers

An error reporting system within the operating system of a computer that provides error reporting and/or debugging for managed applications. The error reporting service supports a registration programming interface through which applications that use non-native or non-standard error reporting functions can register runtime exception modules. A similar interface may be provided for applications to register debuggers. In response to a failure, such as a crash or an application hang, the error reporting service can poll the registered components to ascertain whether any is adapted for use in conjunction with such a failure. If so, the appropriate registered components can be used to collect failure data and/or debug the failed application. In this way, the error reporting service, and an existing framework that supports aggregation of application error reports, can be customized, including to allow error reporting and debugging of non-native applications.

System and method for customized error reporting

Systems and methods are described for coordinating error reporting among a plurality of managed runtimes that are concurrently executing in the same process. In accordance with various embodiments, an error reporting manager that executes concurrently in the same process as the managed runtimes coordinates error reporting among the managed runtimes in a manner that does not require the managed runtimes to be aware of each other or to communicate directly with each other.

Coordination of error reporting among multiple managed runtimes in the same process

A profiler manager may attach and detach profilers from a running application. A profiler may be detached through a two step process where the profiler is sealed from communicating with the running application, then an evacuation step where the application is able to complete any responses that are pending. While the profiler is in the evacuation phase, another profiler may be attached to the application. Messages to the evacuating profiler may be captured and directed to the proper profiler.
