摘要： A compiler requires normal exceptions that are throwable by a method to be either explicitly declared or else "caught" by appropriate exception handlers in the method to be compiled. This ensures that all normal exceptions thrown will be handled by a programmer specified exception handler. The compiler inspects all instructions in a specified method that throw exceptions and all instructions that invoke other methods, and determines whether each type of exception throwable by those instructions and invocable methods is (A) a serious exception (i.e., not a normal exception), (B) is caught by an enclosing exception handler, or (C) is explicitly declared in the method header of the specified method. If any throwable exception cannot be so categorized, that means the throwable exception is a normal exception that is not caught by an enclosing exception and is not explicitly declared in the method header, which means that the method to be compiled is not well formed. As a result, the compiler rejects the specified method, aborting compilation and generating an appropriate error message. The compiler determines the set of throwable exceptions in part by inspecting the methods that are invocable by the specified method for declarations of throwable exceptions. When initiating execution of the specified method, the program execution system inspects the method's declaration of throwable exceptions and blocks execution of the specified method unless exception handlers have been established for handling all the exceptions, if any, included in the declaration.
摘要翻译：一个编译器需要正常的异常，这些异常可以被一个方法抛出，要在被编译的方法中被明确声明或被适当的异常处理程序“捕获”。这样可以确保抛出的所有正常异常都将由程序员指定的异常处理程序处理。编译器检查指定方法中的所有指令，抛出异常和调用其他方法的所有指令，并确定这些指令和可调用方法可抛出的每种异常类型是否为（A）严重异常（即不是正常异常），（B）被封闭的异常处理程序捕获，或者（C）被明确地声明在指定方法的方法头中。如果任何可抛出的异常不能被分类，那意味着可抛出的异常是一个正常的异常，它不被封闭的异常所捕获，并且没有在方法头中被明确声明，这意味着要编译的方法形式不是很好。因此，编译器会拒绝指定的方法，中止编译并生成相应的错误消息。编译器通过检查通过指定的方法可调用的方法来确定可抛出异常的集合，以声明可抛出的异常。当启动指定方法的执行时，程序执行系统会检查方法的可抛出异常声明并阻止执行指定的方法，除非已经建立了异常处理程序来处理声明中包含的所有异常（如果有的话）。

摘要： In summary, the present invention is a multithreaded computer system having a memory that stores a plurality of objects and a plurality of procedures. Each object has a lock status of locked or unlocked, and includes a data pointer to a data structure. The system uses a first object locking procedure to service lock requests on objects that have never been locked as well as object that have not recently been locked, and uses a second object locking procedure to service lock requests on locked objects and object that have been recently locked. The first object locking procedure has instructions for changing a specified unlocked object's lock status to locked, for copying the data structure referenced by the data pointer to an enlarged data structure including a lock data subarray for storing lock data, and for updating the data pointer to point to the enlarged data structure. The second object locking procedure has instructions for updating a specified object's stored lock data. A lock data cleanup procedure, executed when the system's garbage collection procedure is executed, releases the lock data subarray of a specified object if the object has not been recently locked.

摘要： A peer-to-peer platform that may provide mechanisms through which peers may discover each other, communicate with each other, and cooperate with each other to form peer groups is described. The peer-to-peer platform may comprise several layers including a peer-to-peer platform layer, a peer-to-peer services layer, and a peer-to-peer applications layer. At the highest abstraction level, the peer-to-peer platform may be viewed as a set of protocols. Each protocol may be defined by one or more messages exchanged among participants of the protocol. In one embodiment, the peer-to-peer platform may include, but is not limited to, one or more of a peer discovery protocol, a peer resolver protocol, a peer information protocol, a peer membership protocol, a pipe binding protocol, and an endpoint routing protocol. To underpin this set of protocols, the peer-to-peer platform may define a number of concepts including peer, peer group, advertisement, message, pipe, and endpoint.

摘要： A system and method for providing peer groups in a peer-to-peer environment. A peer group may be one or more peers in a peer-to-peer environment that share a set of network services and content. A peer group may define an implicit scope for messages originating from members peers of the peer group. A peer group may provide redundant services and content for greater reliability. In one embodiment, interaction among peers and peer groups in the peer-to-peer environment may be implemented using protocols that are platform-independent as to programming language implementations and network transports. In one embodiment, peers may discover existing peer groups and join the existing peer groups. In one embodiment, peers may create new peer groups.

摘要： A computer processor includes a number of register pairs LOCKADD/LOCKCOUNT to hold values identifying when a computer resource is locked. The LOCKCOUNT register is incremented or decremented in response to lock or unlock instructions, respectively. The lock is freed when a count associated with the LOCKCOUNT register is decremented to zero. In embodiments without LOCKOUT registers, the lock may be freed on any unlock instruction corresponding to the lock. In some embodiments, a computer object includes a header in which two header LSBs store: (1) a LOCK bit indicating whether the object is locked, and (2) a WANT bit indicating whether a thread is waiting to acquire a lock for the object.

摘要： A processor includes logic for attaining a very fast exception handling functionality while executing non-threaded programs by invoking a multithreaded-type functionality in response to an exception condition. The processor, while operating in multithreaded conditions or while executing non-threaded programs, progresses through multiple machine states during execution. The very fast exception handling logic includes connection of an exception signal line to thread select logic, causing an exception signal to evoke a switch in thread and machine state. The switch in thread and machine state causes the processor to enter and to exit the exception handler immediately, without waiting to drain the pipeline or queues and without the inherent timing penalty of the operating system's software saving and restoring of registers.

摘要： Embodiments of a system and method for establishing reliable connections between peers in a peer-to-peer networking environment. In one embodiment, a reliable communications channel may use transmit and receive windows, acknowledgement of received messages, and retransmission of messages not received to provide reliable delivery of messages between peers in the peer-to-peer environment. In one embodiment, each message may include a sequence number configured for use in maintaining ordering of received messages on a receiving peer. A communications channel may make multiple hops on a network, and different hops in the connection may use different underlying network protocols. Communications channels may also pass through one or more firewalls and/or one or more gateways on the network. A communications channel may also pass through one or more router (relay) peers on the network. The peers may adjust the sizes of the transmit and receive window based upon reliability of the connection.

摘要： A system and method for establishing communications channels between and among peers in a peer-to-peer networking environment. Pipes may be used as communication channels for sending and receiving messages and other data between services or applications over input and output endpoints. Pipes may be asynchronous, unidirectional, stateless and unreliable. Bidirectional pipes may also be supported. Pipes may have ends that may be moved around and bound to different peers at different times. Point-to-point and propagate pipes may be supported. Pipes may connect peers that have a direct physical link and peers that do not have a direct link. Peers may communicate through pipes without knowing on which peer a pipe endpoint is bound. A message is sent to all peer endpoints currently connected (listening) to the pipe. The set of connected endpoints may be obtained from a pipe service using a pipe binding protocol.
