摘要： A system and method for providing exceptional flow control in protected code through memory layers. Code is generated. The generated code includes a sequence of normal operations and is subject to protection against copying during execution of the generated code. The generated code is instantiated as a master process into a master layer in a memory space. The master process is cloned by instantiating a copy of the master process as a child layer in the memory space. Execution points within the generated code are identified. A copy of at least a portion of the generated code containing each execution point as an exception layer is instantiated in the memory space. The generated code in the exception layer is patched at each identified execution point with operations exceptional to the normal operations sequence and which are performed upon a triggering of each execution point during execution of the generated code.

摘要： Techniques for assuring thread rendezvous for a plurality of threads executing in a computing system are disclosed. Techniques can be used to assure thread rendezvous for read-only code in a manner that is more efficient than polling techniques. A Light-weight, Yet Trappable On Demand (LYTOD) instruction can be generated for code that is executed by one or more threads. Typically, a LYTOD instruction is generated at critical points of the code in order to assure safe-point thread rendezvous. The LYTOD is a lightweight instruction that can change its behavior from a lightweight instruction to an instruction that causes a trap when executed. The LYTOD can, for example, be implemented as a read-from-memory instruction that operates to load a register with a content of a valid memory location.

摘要： One embodiment of the present invention provides a system that executes an application designed for one application framework in a different application framework. First, the system receives an application designed to operate in the first application framework. The system determines a first set of security permissions used by the application in the first application framework, and maps these security permissions into a second set of security permissions associated with the second application framework. The system then configures the second application framework to provide the second set of security permissions. These steps allow the application to execute transparently in the second application framework with substantially similar security behavior as in the first application framework.

摘要： Techniques are disclosed for sharing programmatic modules among isolated virtual machines. A master JVM process loads data from a programmatic module, storing certain elements of that data into its private memory region, and storing other elements of that data into a “read-only” area of a shareable memory region. The master JVM process copies loaded data from its private memory region into a “read/write” area of the shareable memory region. Instead of re-loading the data from the programmatic module, other JVM processes map to the read-only area and also copy the loaded data from the read/write area into their own private memory regions. The private memory areas of all of the JVM processes begin at the same virtual memory address, so references between read-only data and copied data are preserved correctly. As a result, multiple JVM processes start up faster, and memory is conserved by avoiding the redundant storage of shareable data.
摘要翻译：公开了用于在隔离的虚拟机之间共享程序化模块的技术。主JVM进程从编程模块加载数据，将该数据的某些元素存储到其专用存储器区域中，并将该数据的其他元素存储到可共享存储器区域的“只读”区域中。主JVM进程将加载的数据从其专用存储器区域复制到可共享内存区域的“读/写”区域。代替从编程模块重新加载数据，其他JVM进程映射到只读区域，并将加载的数据从读/写区域复制到其自己的专用存储器区域中。所有JVM进程的专用内存区域都从同一个虚拟内存地址开始，因此只读数据和复制的数据之间的引用被正确保存。因此，多个JVM进程启动速度更快，并且通过避免可共享数据的冗余存储来节省内存。

摘要： A system and method for dynamically and persistently tracking incremental profiling data in a process cloning application environment is presented. A master runtime system process is executed. A memory space of the master runtime system process is cloned as a child runtime system process responsive to a process request. The child runtime system process is executed. The execution of the child runtime system process is profiled by collecting profiling data incrementally. The child runtime system process profiles are fed back to the master runtime system process to benefit subsequent cloned child runtime system processes. In a further embodiment, the child runtime system process profiles are maintained in a persistent storage for use by the master runtime system process upon the next start up.

摘要： A method and system that reduces the space allocated for internal data structures by a runtime engine. The internal data structures store member information for preloaded classes used by applications executed by the runtime engine. The system determines the different types of internal data structures represented in the classes and identifies thee possible values of each type's members. The system next determines the amount of space required to store the values for each type in a respective value table and the number of bits needed to index each entry of that table. The system determines based on the stored information whether occurrences of a member are optimally represented as a set of value table indices and a value table or, in the conventional manner, as a general variable that stores the member's value for each occurrence. The system then emits appropriate information for the member and its parent data structure.
