摘要： A fast division technique is provided to calculate the address of a slot in a paged object, when the slot is located on a different page than the beginning of the object. The fast division technique employs arithmetical-logical operations of shifting and masking, that are faster than most hardware implementations of integer division and modulus, respectively. In one aspect, the use of these operations is facilitated by requiring the page size and the size of the page header to be a power of two.

摘要： Methods of memory management in a run-time environment are described. A mechanism is provided for registering a routine to deinitialize or deallocate a large object at the end of a call (e.g. by setting it to null to unreference the object), which prevents the large object from being migrated into session memory, e.g. when live objects are migrated at the end of the call. This routine is called after the finalization of garbage collected objects that may use the large object. In a subsequent call, the large object is checked before use to determine if the object is deinitialized and re-initialized if the large object was deinitialized.
摘要翻译：描述运行时环境中的内存管理方法。提供了一种机制，用于在呼叫结束时（例如通过将其设置为空以取消对对象的重定位）来注册例程以对大对象进行去初始化或解除分配，这防止大对象迁移到会话存储器，例如，活动结束时迁移活动对象。在可能使用大对象的垃圾收集对象的最终化之后调用此例程。在随后的调用中，在使用之前检查大对象以确定对象是否已初始化，如果大对象已初始化，则重新初始化该对象。

摘要： Techniques for memory management or analysis with conservative garbage collectors is provided. The native stack is analyzed during runtime to identify within frames references to objects in the heap space. An amount of memory is calculated that represents the memory implicated by the reference. A log can be generated that conveys the frame, location of the reference in the frame and amount of memory implicated by the reference.

摘要： A method and apparatus for copying garbage collection is described. A set of ambiguously referenced objects is identified in a from-space. Live objects in the from-space which are not ambiguously referenced are moved to the to-space, and the ambiguously referenced are transfixed (i.e. left behind to reside in the from-space). The boundaries of the ambiguously referenced are determined. When moving objects to the to-space, the objects are moved into regions between boundaries of objects transfixed in the to-space.

摘要： A heap analyzer that processes a snapshot of the heap contained in a dump file is described. The heap analyzer tool can be configured to relocate the pointers in the dumped heap and allow developers to examine the heap in web browser by presenting markup for displaying a heap object in the browser and rendering pointers in the object as clickable links. When a link is selected, the pointer is followed to another object and markup is generated for rendering that object with its links. Furthermore, callbacks may be provided through an application programming interface (API) to allow developers to furnish their own code for analyzing and displaying their data structures.

摘要： Methods for managing memory in a run-time environment are described, in which an object is activated by both initializing the object and registering a routine to deallocate or deactivate the object at the end of a call (e.g. by setting it to null to unreference the object), which prevents the object, which may be a large object, from being migrated into session memory. This deactivation routine is called after the finalization of garbage collected objects that may use the object. In a subsequent call, the object is checked before use to determine if the object is already activated and re-initialized if the object is not activated.

摘要： A method and software for performing data migration is described in which a common data migration driver routine is provided to handle various and disparate kinds of migration operations in a conceptually unified manner. Differences between the migration operations are handled by variations in how the state of the data migration driver routine is initialized, including pointers to low-level routines. Furthermore, a table of actions can be used to direct the basic operation of object copying, external reference created, and object interning.

摘要： A method and software for analyzing a heap is described, in which a snapshot is made of a heap, which can be later analyzed by an analysis tool when a program that had run out of memory is no longer running. In one embodiment, an object allocated by the program is accessed and copied into a file, and an address of the object allocated by the process is recorded in association with an offset in the file of the copy of the object. The copy of the object copied into the file has preferably the same size as the object allocated by the process. A heap analysis tool may then be run on the objects copied into the file.
