摘要： Techniques are provided for performing OID-to-VMA translations during runtime. Vector registers are used to implement a “software TLB” to perform OID-to-VMA translations. Runtime dereferencing is performed using one or more vector registers to compare each OID that needs to be dereferenced against a set of cached OIDs. When a cached OID matches the OID being dereferenced, the VMA of the cached OID is retrieved from cache. Buffer cache items may be pinned during the period in which the software TLB stores entries for the items. The cache of OID translation information may be single or multi-leveled, and may be partially or completely stored in registers within a processor. When stored in registers, the translation information may be spilled out of the register, and reloaded into the register, as the register is needed for other purposes.
摘要翻译：提供了在运行时执行OID到VMA翻译的技术。矢量寄存器用于实现“软件TLB”来执行OID到VMA的翻译。使用一个或多个向量寄存器执行运行时取消引用，以将需要取消引用的每个OID与一组缓存的OID进行比较。当缓存的OID与取消引用的OID匹配时，缓存的OID的VMA从缓存中检索。在软件TLB存储项目的条目的时段期间，可能会固定缓冲区缓存项目。 OID翻译信息的缓存可以是单级或多级，并且可以部分地或完全地存储在处理器内的寄存器中。当存储在寄存器中时，翻译信息可以从寄存器中溢出，并重新加载到寄存器中，因为寄存器需要用于其他目的。

摘要： Techniques are described for unifying static and dynamic compiler optimizations in source code bases. In an embodiment, a first compiler compiles source code of a target function to generate ahead-of-time (AOT) compiled machine code. A second compiler compiles the source code to generate an intermediate representation (IR) of the target function. In response to determining that the target function should be just-in-time (JIT) compiled, the AOT-compiled machine code for the target function is linked to the IR of the target function. During runtime, a physical processor executes AOT-compiled machine code of an executable program. When the target function is encountered for the first time, a JIT compiler is invoked. The JIT compiler generates JIT-compiled machine code for the target function. The physical processor executes the JIT-compiled machine code in place of the AOT-compiled machine code for the target function.
摘要翻译：描述了在源代码库中统一静态和动态编译器优化的技术。在一个实施例中，第一编译器编译目标函数的源代码以生成预先（AOT）编译的机器码。第二个编译器编译源代码以生成目标函数的中间表示（IR）。响应于确定目标函数应该是即时编译（JIT），目标函数的AOT编译机器代码链接到目标函数的IR。在运行时，物理处理器执行AOT编译的可执行程序的机器代码。当第一次遇到目标函数时，将调用JIT编译器。 JIT编译器为目标函数生成JIT编译的机器代码。物理处理器执行JIT编译的机器代码，代替目标函数的AOT编译机器代码。

摘要： A method and apparatus for processing path-based database operations is provided. According to one aspect, a path cache is maintained. For each hierarchical node that is traversed during a path-determining operation, it is determined whether a cache entry corresponding to that node is already contained in the path cache. If such a cache entry is already contained in the path cache, then the path indicated in that cache entry is used to complete the pathname for the node for which the operation is being performed. As a result, hierarchically higher nodes do not need to be traversed to complete the operation. Alternatively, if such a cache entry is not already contained in the path cache, then a cache entry for the node currently being traversed is generated and inserted into the path cache for use in subsequent path-determining operations.
摘要翻译：提供了一种用于处理基于路径的数据库操作的方法和装置。根据一个方面，维护路径高速缓存。对于在路径确定操作期间遍历的每个分级节点，确定与该节点相对应的高速缓存条目是否已经包含在路径高速缓存中。如果这样的缓存条目已经包含在路径缓存中，则使用该缓存条目中指示的路径来完成正在执行该操作的节点的路径名。因此，不需要遍历层次更高的节点来完成操作。或者，如果这样的高速缓存条目尚未包含在路径高速缓存中，则生成用于当前正在遍历的节点的高速缓存条目并将其插入到路径高速缓存中以用于随后的路径确定操作。

摘要： A method and apparatus for managing relationships between resources stored in a repository is provided. A client sends, to a server, a request to store a first resource within a repository. In response to receiving the request, the server parses the first resource to retrieve relationship data that identifies a relationship between two or more resources to be stored, or currently stored, within the repository. The server stores, within a database accessible to the server, one or more relationship records that identify the relationship between the two or more resources. The one or more relationship records are stored separate from the two or more resources. Subsequently, the client may issue queries, to the server, about the one or more relationships records stored in the database. In this way, a user may access the one or more relationship records to analyze the relationship between resources stored in repository.

摘要： Systems, methods, and other embodiments associated with providing an XML-based translation service are described. One method embodiment includes accessing a translation-aware XML document that may comply with a translation-enabling XML schema. The document may store a first XML element that stores translatable data and a second XML element that stores a translation of the translatable data. The schema may describe that the first XML element includes a first identifier that identifies the first element as storing translatable data. The schema may also describe that the second XML element includes a second identifier that identifies the second element as storing a translation for translatable data. The method may also include establishing a session language identifier and providing a virtual view of the translation-aware XML document, the virtual view being determined, at least in part, by the session language identifier.

摘要： A method and storage media for performing access resolution using ACL types is provided. Under an AND semantic, an intersection set formed from the types of multiple ACLs protecting a resource may be utilized to efficiently determine whether a request for a privilege to access the resource is granted or denied. If the privilege is not a member of the intersection set, the privilege cannot be granted. A union set may be used for an OR semantic. A global ACL type may represent all privileges system-wide or application-wide. A global ACL may represent a system-wide or application-wide access policy. A conjunction of a global ACL and a regular ACL may be stored in a cache. The union set, intersection set, or access resolution may also be cached for subsequent request processing.
摘要翻译：提供了一种使用ACL类型执行访问分辨率的方法和存储介质。在AND语义下，可以利用从保护资源的多个ACL的类型形成的交集，以有效地确定是否授予或拒绝访问资源的特权请求。如果权限不是交集集的成员，则不能授予权限。联合集合可以用于OR语义。全局ACL类型可以表示系统范围或应用程序范围内的所有权限。全局ACL可以表示全系统或应用程序范围的访问策略。全局ACL和常规ACL的连接可以存储在缓存中。联合集，交集或访问分辨率也可被缓存以用于后续请求处理。

摘要： A method and apparatus for sharing state information among a plurality of servers is provided. A first server receives a request to perform a file operation, such as a NFS file system operation. Thereafter, the first server updates state information to reflect a change in state associated with processing the request. The first server then causes state update information, which identifies the change in state that was made at the first server, to be propagated to a second server. The second server updates state information, stored at the second server, to reflect the change in state associated with processing the request at the first server. Advantageously, a client may send a series of stateful file operations to either the first server or the second server, even if processing any one of the stateful file operation requests requires knowledge of the state of processing prior requests in the series of requests.
摘要翻译：提供了一种用于在多个服务器之间共享状态信息的方法和装置。第一服务器接收执行诸如NFS文件系统操作之类的文件操作的请求。此后，第一服务器更新状态信息以反映与处理请求相关联的状态变化。然后，第一服务器导致状态更新信息，其标识在第一服务器处进行的状态的改变，以被传播到第二服务器。第二服务器更新存储在第二服务器处的状态信息，以反映与在第一服务器处理请求相关联的状态变化。有利地，客户机可以向第一服务器或第二服务器发送一系列有状态的文件操作，即使处理有状态文件操作请求中的任何一个需要知道在一系列请求中处理先前请求的状态。
