摘要： An automated memory management or garbage collection routine uses a first garbage collection routine to perform garbage collection on new objects, and a second garbage collection routine to perform garbage collection on old objects. The two garbage collection routines are operated concurrently, with each routine separately marking objects to be reclaimed. The second routine may operate in a background mode by traversing a tree of objects from a copy of memory, while the first routine may operate on actual memory.
摘要翻译：自动内存管理或垃圾收集例程使用第一个垃圾收集例程来对新对象执行垃圾收集，以及第二个垃圾收集例程来对旧对象执行垃圾收集。两个垃圾收集例程同时运行，每个例程分别标记要回收的对象。第二例程可以在背景模式下通过从存储器的副本中遍历一个对象树，而第一例程可以在实际存储器上操作。

摘要： Per-segment overflow ranges. One method includes acts for handling overflows of a mark stack. A reference to an object is accessed. The object is processed by attempting to place references to other objects referenced in the object onto a mark stack. An overflow condition of the mark stack is detected. A range in a segment is defined which includes the object that caused the overflow condition. The range is assigned on a per segment basis such that the range is defined to only include addresses in a single segment.

摘要： Adding references to objects to a mark stack. A limited number of references to objects referenced by an object with a large number of object references are added to the stack. An object is accessed. A determination is made that references in the object should be added to a mark stack using a reference in the mark stack to the object in conjunction with a pointer. The pointer is used to track which references in the object have been placed on the mark stack. A reference to the object on the mark stack is accessed. A pointer is initialized. A reference to another object referenced by the object is pushed onto the mark stack. The pointer is incremented. It is then determined that that more references should be pushed to the mark stack. Acts of pushing references onto the mark stack and incrementing the pointer are repeated.

摘要： 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.

摘要： A system and method is provided to facilitate communications between object systems. A caller is provided having optimized in-lined functionality when initiating a remote function call between managed and unmanaged object systems, for example. The in-lined functionality includes utilizing direct calls and returns within a calling function. In this manner, pushing additional arguments onto an execution stack because of an external stub reference is mitigated. In addition, one or more code loops can be analyzed to enable stack markers to be “hoisted” and thus pushed a single time instead of each time the calling function executes. Other aspects of the optimized caller provide garbage collection and thread management, security attribute checking on outgoing calls, calling convention considerations, wherein arguments and return values are organized according to the convention utilized by the remote object system, and in-lined marshalling to provide enhanced performance over external stub code references. Code extensibility options can be included enabling functions to be generalized thereby insulating object systems from implementation details of the called functions.
摘要翻译：提供了一种系统和方法来促进对象系统之间的通信。例如，在启动被管理对象系统和非托管对象系统之间的远程函数调用时，提供一个具有优化内嵌功能的调用者。嵌入式功能包括在调用功能中使用直接调用和返回。以这种方式，由于外部存根引用将附加参数推送到执行堆栈得到缓解。此外，可以分析一个或多个代码循环，以使堆栈标记“挂起”，从而推动一次，而不是每次调用函数执行。优化的呼叫者的其他方面提供垃圾收集和线程管理，对呼出的呼叫的安全属性检查，调用惯例注意事项，其中参数和返回值根据远程对象系统使用的惯例进行组织，并且内联编组以提供增强的对外部存根代码引用的性能。可以包括代码可扩展性选项，使得功能得以泛化，从而将对象系统与被调用函数的实现细节隔离。

摘要： A garbage collection system and method in a multiprocessor environment having a shared memory wherein two or more processing units participate in the reclamation of garbage memory objects. The shared memory is divided into regions or heaps and all heaps are dedicated to one of the participating processing units. The processing units generally perform garbage collection operations, i.e., a thread on the heap or heaps that are dedicated to that the processing unit. However, the processing units are also allowed to access and modify other memory objects, in other heaps when those objects are referenced by and therefore may be traced back to memory objects within the processing units dedicated heap. The processors are synchronized at rendezvous points to prevent reclamation of used memory objects.

摘要： A method of reclaiming unused memory objects in a computing system includes traversing memory objects referenced by a program; marking the memory objects reached; adding the memory objects reached to a mark-list; detecting if the mark-list if full; and if the mark-list is full, sweeping the memory objects, and reclaiming the memory objects not marked. A system for reclaiming unused memory objects in a computing system includes a traverse module, a mark module, a record module, a mark-list module, a sweep module, and a reclaim module. The traverse module traverses memory objected reference by a program. The mark module marks the memory objects reached. The record module adds the memory objects reached to a mark-list. The mark-list module detects if the mark-list is full. The sweep module sweeps the memory objects if the mark-list is full. And, the sweep module skips the unmarked objects if the mark-list is not full. The reclaim operation reclaims the memory objects not marked.
