摘要： A computer method and system for passing a pointer to an interface from a server process to a client process. In a preferred embodiment, the server process instantiates an object that has multiple interfaces. The server process identifies an interface to pass to the client process and creates a stub object for receiving a request to invoke a function member of the interface and for invoking the requested function member upon receiving the request. The server process then sends an identifier of the stub to the client process. When the client process receives the identifier of the stub, it instantiates a proxy object for receiving requests to invoke a function member of the interface and for sending the request to the identified stub. The client process can then invoke the function members of the interface by invoking function members of the proxy object. The proxy object sends a request to the identified stub. The identified stub then invokes the corresponding function member of the interface.

摘要： Communication among agile objects and context-bound objects within object-oriented programming environments, including communication across contextual boundaries, is disclosed. In one embodiment, a reference to a second object within a second context is wrapped in a proxy wrapper. A first object within a first context calls the second object via the wrapped reference. No direct reference is held by the first object to the second object. Other embodiments relate to agile objects. Agile objects called by context-bound objects execute in the contexts of their callers. The context of a calling context-bound object becomes the context of an agile object for calling of the agile object by the calling context-bound object. Direct reference to the agile object by the context-bound object is thus permitted.

摘要： An object system provides composable object execution environment extensions with an object model that defines a framework with contexts, policies, policy makers and activators that act as object creation-time, reference creation-time and call-time event sinks to provide processing of effects specific to the environment extensions. At object creation time, an object instantiation service of the object system delegates to the activators to establish a context in which the object is created. The context contains context properties that represent particular of the composable environment extensions in which the object is to execute. The context properties also can act as policy makers that contribute policies to an optimized policy set for references that cross context boundaries. The policies in such optimized sets are issued policy events on calls across the context boundary to process effects of switching between the environment extensions of the two contexts.

摘要： A method and system for delayed registration of a remote protocol for communicating between a client computer system and a server computer system. The server computer system has a communications process that registers a plurality of protocols. When the client process needs to communicate with the server process, it sends a request to the communications process along with an indication of the protocols that it supports. The communications process selects a protocol that is supported by both the client computer system and the server computer system and directs the server process to register that protocol. The communication process provides the server endpoint for that protocol to the client process which can then communicate directly with the server process.

摘要： A computer-based method and system for accessing objects of different thread types in a single process. The system provides single-threaded apartments (STAs) for loading apartment-threaded objects and a multi-threaded apartment (MTA) for loading free-threaded objects. Each STA has a single thread, and the MTA has multiple threads. When an STA thread requests to access a free-threaded object, the system creates an MTA thread and requests the MTA thread to instantiate the free-threaded object. The STA thread then receives a marshalled pointer to the free-threaded object and unmarshals the received pointer. The STA thread then accesses the free-threaded object using the unmarshalled pointer so that the MTA thread accesses the free-threaded object on behalf of the STA thread. When an MTA thread requests access to an apartment-threaded object, the system creates an STA thread and requests the STA thread to instantiate the apartment-threaded object. The MTA thread then receives a marshalled pointer to the apartment threaded object and unmarshals the received pointer. The MTA thread then accesses the apartment-threaded object using the unmarshalled pointer so that the STA thread accesses the apartment-threaded object on behalf of the MTA thread.

摘要： A method and system for preventing incorrect information from corrupting server object information maintained by a client machine. A DCOM client machine is provided with object reference information for accessing remote objects. DCOM unmarshals the information into server object information, including an object identifier and string bindings of a remote resolver through which the client machine may contact the remote server to obtain string bindings for that remote object. Each resolver string bindings received by a client machine are compared against known resolver string bindings and each unique permutation of string bindings is associated with a unique machine identifier locally generated therefor. Each object identifier is paired with its corresponding unique machine identifier so that all references to a remote object include the identity of the machine on which the object was created.

摘要： A single programming model is provided for accessing a plurality of distinct message transports while developing one or more applications for message delivery between two endpoints. The programming model allows for independently configurable assurances and features for transporting the messages. The configurable assurances may be selected from at least once delivery, at most once message delivery, in order message delivery, and message time to live. The independently chosen features may include a session state storage, an extension of time to live, and transacted message buffering.

摘要： The present invention extends to methods, systems, and computer program products for maintaining message state at a cursor. A message consumer requests messages from a cursor. The cursor can maintain state information for the message consumers separately from a message log that stores messages. Any of a variety of message delivery assurances can be used when delivering a message to a message consumer.

摘要： The present invention monitors the receipt of messages between two endpoints on established sequence session in accordance with a Reliable Messaging protocol for Web Services (RM-WS protocol). The messages received may be application or infrastructure messages (e.g., acknowledgement messages in accordance with the RM-WS protocol). Further, the present invention defines a time period known as the inactivity timeout, which is an upper limit to the time that may pass without receiving a message (either application or infrastructure) on the sequence session. Based on this inactivity timeout period, the present invention calculates time periods for sending idempotent infrastructure messages in accordance with the RM-WS protocol for verifying and maintaining connection liveliness.

摘要： The present invention extends to methods, systems, and computer program products for maintaining message state at a message log. Messages are accumulated at a message log in accordance with a message retention policy. Any of a variety of message capture assurances can be used when capturing a message from a message producer within a message log. A message becomes visible to message consumers after the outcome of writing the message is known (either failure or success). Messages are requested using (e.g., monotonically increasing) sequence numbers. Messages are also dropped from the message log in accordance with the message retention policy.
