A system and method, useful in tracing program execution, for serializing data, such as an object data, into consistent, structured (e.g., XML) output. A serializer processes an object's data, and for each set of data, records the object's data in a structured (e.g., XML) format that reflects the object's current state. Nodes corresponding to fields and properties of the object are nested in the structure. Simple types define nodes with the current data value associated with the tag. More complex types including arrays, collections, dictionaries and exceptions are stored as individual members of a type, with any complex members further broken down into sub-nodes. Object data including custom collections, dictionaries, non-public fields and properties and properties with only get-accessor are serialized. The resulting output, such as in an XML formatted structure, is easy to read by humans, and is easily processed, such as for automated analysis purposes.

A method, system, and apparatus for providing a communications channel for inter-object communication are provided. According to the method, a request may be received from a first object executing within a managed code environment to transmit data to a second object. In response thereto, an instant message (“IM”) including the data may be transmitted to an IM server computer. The IM may be forwarded to the managed code environment in which the second object is executing. The IM may then be received by the managed code environment, the data contained therein may be extracted, and the data may be presented to the second object. A reverse path may also be utilized for return communication between objects.

Described is a system and method by which an auxiliary computing device having an auxiliary display platform that displays information corresponding to data that originated on the main computer system may be extended by a device manufacturer. Extended hardware is added to the device, such as a radio receiver and / or an audio decoder. The auxiliary display platform is layered and extensible at each layer, and includes an extensible hardware abstraction layer that is extensible to support extended hardware if needed, and a driver layer that is extensible by adding driver code for the extended hardware. A runtime layer is also extensible to support the extended hardware as needed, as are libraries, the auxiliary shell program and other managed code. The client API is also extensible to allow applications on the main computer system to communicate with extended hardware via the device runtime layer.

Managed code, including applications, runtime, and driver, have a priori knowledge of the client's exact hardware configuration, just as the JIT compiler has a priori knowledge of the microprocessor type on the target computer system. At compile time, the compiler knows the effective version various system drivers, so that the compiler can emit an executable tuned for a particular driver version and target system.

The present invention relates to systems and methods that facilitate dynamic programming language execution in a managed code environment. A class component is provided that declares an inheritance hierarchy for one or more tagged values associated with a dynamic programming language. During execution of the tagged values, a rules component mitigates user-defined types from inheriting or deriving properties from the tagged values in order to support a type safe runtime environment. A bifurcated class tree is provided that defines non-tagged type elements on one side of the tree and tagged type element values on an alternate branch of the tree. The rules component analyzes runtime extensions that help to prevent data from one component of the tree deriving or inheriting properties from another component of the tree. The runtime extensions include such aspects as cast class extensions, test class extensions, and conversion class extensions for converting data types from one class subtype to another.

A description of the hierarchically-structured document is accessed and converted into an early-bound object having at least some of the same properties as the hierarchically-structured document, and having at least some of the methods that may be performed on the hierarchically-structured document. When a function call is placed to the early-bound object, the early-bound object causes the appropriate corresponding changes to be affected on the hierarchically-structured document while maintaining change tracking information for the document. This reduces the difficulty when drafting source code for a program that interfaces with hierarchically-structured documents that can have varying structures and may be governed by complex change tracking rules.

Unsafe application programs that implement managed code can be executed in a secure fashion. In particular, an operating system can be configured to execute an application program in user mode, but handle managed code compilation through a type-safe JIT compiler operating in kernel mode. The operating system can also designate a single memory location to be accessed through multiple address spaces with different permission sets. An application program operating in user mode can be executed in the read / execute address space, while the JIT compiler operates in a read / write address space. When encountering one or more pointers to intermediate language code, the application runtime can send one or more compilation requests to a kernel mode security component, which validates the requests. If validated, the JIT compiler will compile the requested intermediate language code, and the application program can access the compiled code from a shared memory heap.

The illustrative embodiments provide a computer implemented method, apparatus, and computer program product for accelerating execution of a program, written in an object oriented programming language, in an emulated environment. In response to receiving a request for an accelerated communications session from a guest virtual machine in the emulated environment, a native virtual machine is initiated external to the emulated environment but within the computing device hosting the emulated environment. Thereafter, an accelerated communications link is established between the guest virtual machine and the native virtual machine. The accelerated communications link enables a transfer of managed code between the guest virtual machine and the native virtual machine. The managed code is then executed by the native virtual machine.

A system and method is provided for efficiently pinning references to the managed heap. The system and method allow for references to managed objects to be declared as pinned during a call to unmanaged code. The references are then reported as pinned to a garbage collector in response to invocation of a garbage collection service. The reference can be declared as pinned by a programmer within the source code or automatically invoked at run-time based on an unsafe condition. The garbage collection service will not move or relocate objects that are referenced by the active pinned local variables. If a garbage collection does not occur, the fact that the local variables are declared pinned is ignored.

A processor comprising one or more control units, a plurality of first execution units, and one or more second execution units. Fetched instructions that conform to a processor instruction set are dispatched to the first execution units. Fetched instructions that conform to a second instruction set (different from the processor instruction set) are dispatched to the second execution units. The second execution units may be configured to performing graphics operations, or other specialized functions such as executing Java bytecode, managed code, video / audio processing operations, encryption / decryption operations etc. The second execution units may be configured to operate in a coprocessor-like fashion. A single control unit may handle the fetch, decode and scheduling for all the executions units. Alternatively, multiple control units may handle different subsets of the executions units.

A method and apparatus for providing instrumentation data to an instrumentation data source from within a managed code environment is provided. A decoupled provider is provided that executes partially in managed code and partially in unmanaged code. The decoupled provider facilitates communication with an instrumentation data source. The decoupled provider also dynamically registers schema for managed code objects to be instrumented at run-time. The decoupled provider also receives and processes requests from the instrumentation data source to retrieve instance data for managed code objects, to write properties on managed code objects, and to execute methods on managed code objects.

In the access control model of security, an access control matrix associates rights for operations on objects with subjects. An approach for assigning rights to code at run-time involves determining the run-time rights of a piece of code by examining the attributes of the pieces of code that have run (including their origins) and any explicit requests to augment rights. Thus, this approach relies on the execution history for security. This history based approach reduces the difficulties and the error-proneness of securing extensible software systems.

An instrumentation client API is provided within a managed code runtime environment for accessing instrumentation data that resides outside of the managed code runtime environment. The instrumentation client API provides access to instrumentation data in a manner that is consistent with the classes and models provided by the runtime environment, raises exceptions in a manner that is compatible with the runtime environment, and is secure. The instrumentation client API wraps, or translates, calls to and from an instrumentation data source external to the runtime environment. The API interacts with an interface provided by the instrumentation data source to provide functionality and connectivity that is not otherwise provided by the instrumentation data source. The API also provides access to instrumentation data in a manner that is consistent with the models and classes provided by the runtime platform. The classes defined by the API return collections and exceptions in a way that is consistent with the managed code runtime platform.

A system and method for facilitating cross-process access into a managed code process is useful in an embodiment of the invention for debugging managed code without perturbing the process being accessed or requiring the code under test to be running during debugging. A compiler according to an embodiment of the invention is used to produce mirror code wherein in-process pointers have been replaced with cross-process pointers in order to mirror the address space of the process under test to the address space of the mirror code process. In a further embodiment, the mirror code process is modified not only to allow but also to optimize the cross-process access.

A base station controller (BSC) of a radio or wireless telecommunications network base station includes a director. A BSC includes multiple central processing units (CPUs), with each CPU running a call-processing application for one or more connections. The director is a logical entity that intercepts wireless call-setup signaling and assigns each corresponding connection to a CPU according to a centralized load-balancing algorithm. The centralized load-balancing algorithm distributes connections to less loaded CPUs to i) prevent individual CPUs from overloading, ii) utilize otherwise unused system resources, and iii) increase overall system performance. The director hosts cell components that manage code division multiple access (CDMA) downlink spreading codes for a base station, providing centralized allocation of spreading codes by the base station.

A system and method for inducing asynchronous behavioral changes in a managed application process is presented. An application manager process is executed. A managed application process is executed. At least one application provided as object-oriented program code under the control of a managed code platform is executed. The managed application process logically communicates with the application manager process. One or more constructors corresponding to notifiable objects provided as object-oriented program code are identified. Each constructor keeps track of instantiated notifiable objects in a list in the managed application process. A change request is broadcast to the managed application process. The notifiable objects tracked by each identified constructor are iterated over to effect a behavioral change in the managed application process.

The present invention provides an object model that exposes speech-related functionality to applications that target a managed code environment. In one embodiment, the object model and associated interfaces are implemented consistently with other non-speech related interfaces supported across a platform.

The method comprises the steps of: receiving code-tracing data from an executing software component; adding the received code-tracing data to a log stored in temporary storage; detecting a property of the received code-tracing data; copying the log to non-volatile storage when the property matches a defined trigger property; and deleting contents of the log according to a caching policy when the property does not match a defined trigger property.

A system and method are provided for modeling structured, semi-structured, and unstructured data all within a single instance of a user defined type (UDT) within a database store. In particular, the XML data model is extended to fields of a UDT. As a result, the properties of the XML data model-such as document order and document structure-can be preserved within instances of a UDT. Moreover, code representing object behavior (i.e., methods that can be invoked on an object in managed code) can be added to the UDT to operate on an XML field, as well as non-XML fields of the UDT. This enables a framework for adding business logic to XML data. The content model of the XML data can be optionally described using XML schema documents associated with the XML fields of the UDT.

Documentation having code samples is managed. Documentation describing programming code for a software product is received. The documentation references a code sample having an associated test module for determining whether the code sample is valid. The code sample is tested by executing the associated test module to produce a test result indicating whether the code sample is valid. The documentation, code sample, and test result are stored. The documentation, code sample, and test result may be provided to a client adapted to display the code sample and test result to a user of the client. Invalid code samples in the documentation may be identified using the test modules and the invalid code samples may be replaced to make the code samples valid.
