摘要： An external request to perform a file operation within a resource manager is received. The resource manager selects a resource manager file identifier that is to be an attribute of a file associated with the file operation. The file operation and the resource manager file identifier are logged in a log entry of a log. Subsequent to logging the log entry, the log entry is accessed during a forward pass through the log, for example, during a roll-forward recovery. If it is determined that the resource manager file identifier in the log entry is assigned to the file, the first log entry is not processed. On the other hand, if it is determined that the resource manager file identifier in the log entry is not assigned to the file, the resource manager file identifier is selected to be assigned to a file when the first log entry is processed.

摘要： A transactional file system wherein multiple file system operations may be performed as transaction. An application specifies that file system-related operations should be handled in a transaction, and is given a file handle associated with a transaction context. For file system requests associated with a transaction context, a file system component manages operations consistent with transactional behavior. The component provides data isolation by providing multiple file versions such that transactional readers do not receive changes until after the transaction commits and the reader reopens the file. The component handles namespace logging operations in a multiple-level log that facilitates logging and recovery. Page data is logged separate from the main log, with signatures establishing whether pages were fully flushed to disk. Namespace isolation via isolation directories allows a transaction to see its operational effects but not effects of other uncommitted transactions. Transactions over a network are facilitated.
摘要翻译：可以作为事务执行多个文件系统操作的事务文件系统。一个应用程序指定文件系统相关的操作应该在事务中处理，并且被赋予与事务上下文关联的文件句柄。对于与事务上下文相关联的文件系统请求，文件系统组件管理与事务行为一致的操作。该组件通过提供多个文件版本来提供数据隔离，以便在事务提交之后事务读取器不会接收更改，并且读取器重新打开该文件。该组件处理多级日志中的命名空间日志记录操作，便于记录和恢复。页面数据与主日志分开记录，签名确定页面是否完全刷新到磁盘。通过隔离目录命名空间隔离允许事务查看其操作效果，但不影响其他未提交的事务。通过网络进行的交易是便利的。

摘要： A method and a processing device are provided for sequentially aggregating data to a write log included in a volume of a random-access medium. When data of a received write request is determined to be suitable for sequentially aggregating to a write log, the data may be written to the write log and a remapping tree, for mapping originally intended destinations on the random-access medium to one or more corresponding entries in the write log, may be maintained and updated. At time periods, a checkpoint may be written to the write log. The checkpoint may include information describing entries of the write log. One or more of the checkpoints may be used to recover the write log, at least partially, after a dirty shutdown. Entries of the write log may be drained to respective originally intended destinations upon an occurrence of one of a number of conditions.

摘要： Aspects of the subject matter described herein relate to storage allocation. In aspects, a hierarchical data structure is used to track allocation data for storage managed by a file system. The hierarchical data structure may have multiple levels with each level having data regarding a different granularity of storage. Portions of the hierarchical data structure may be locked independently of other portions of the hierarchical data structure. The hierarchical data structure may indicate that one or more portions of storage are for exclusive use by a directory. Extra space may be reserved in allocated space in anticipation of subsequent operations. Allocation requestors may obtain storage allocation from regions associated with different levels of the hierarchical data structure.

摘要： Aspects of the subject matter described herein relate to antivirus protection and transactions. In aspects, a filter detects that a file is participating in a transaction and then may cause the file to be scanned together with any changes that have made to the file during the transaction. After a file is scanned, a cache entry may be updated to indicate that the file is clean. The cache entry may be used subsequently for like-type states. For example, if the file was scanned inside a transaction, the cache entry may be used later in the transaction. If the file was scanned outside a transaction, the cache entry may be used later for requests pertaining to files not in a transaction. Cache entries may be discarded when they are invalid or no longer useful.
摘要翻译：本文所述主题的方面涉及防病毒保护和交易。在方面，过滤器检测到文件正在参与事务，然后可能导致文件与事务中对文件所做的任何更改一起进行扫描。扫描文件后，可能会更新缓存条目以指示文件干净。缓存条目可以随后用于类型状态。例如，如果文件在事务中被扫描，则高速缓存条目可以在事务中稍后使用。如果文件在事务之外被扫描，则缓存条目可以稍后用于与不在事务中的文件相关的请求。缓存条目无效或不再有用时可能会被丢弃。

摘要： A common logging system (a “virtual logging system”) that presents to one or more log clients the appearance that each log client is interacting with a dedicated logging system. In reality, the virtual logging system is multiplexing virtual log streams, including log records, for each log client into a single transactional log. In particular, the invention is directed at a system and method for decoupling space reservation between a plurality of distributed components and a core component in the virtual logging system.

摘要： Aspects of the subject matter described herein relate to transactions. In aspects, a consistency requester such as a shadow copy service requests to have a consistent view of a set of resources. In response, transactions that are in a problematic state are allowed to exit the problematic state while new and existing transactions that are not in the problematic state are allowed to perform any work except work that takes them into the problematic state. After no transactions are in the problematic state, a consistent view of the set of resources is available. This view may be used by the consistency requester as desired. Afterwards, the consistency requester may indicate that a consistent view is no longer needed. Transactions are then allowed to enter the problematic state. Transactions may also be allowed to enter the problematic state if a timeout elapses.
摘要翻译：本文描述的主题的方面涉及交易。在一些方面，诸如卷影副本服务的一致性请求者请求具有一组资源的一致视图。作为回应，处于有问题状态的事务被允许退出有问题的状态，而不能处于问题状态的新的和现有的事务被允许执行任何工作，除了使它们进入有问题的状态的工作。在没有交易处于问题状态之后，可以使用一组资源的一致视图。该视图可以由所需的一致性请求者使用。之后，一致性请求者可能表示不再需要一致的视图。然后允许交易进入有问题的状态。如果超时，也可允许交易进入问题状态。

摘要： A system and method supporting multiple independent transactional resource managers on a single logical volume, in which each resource manager is a unit of storage management. Each resource manager independently maintains metadata associated with a collection of files that are contained within the scope of a resource manager, such as the files within a subdirectory corresponding to the resource manager. A general architecture allows databases or other entities to integrate with a transactional file system volume via the resource managers, whereby each database has its files independently associated with a transactional resource manager such that database operations do not affect other operations on the volume. Having independent resource managers allows different levels of performance, reliability, feature availability, and manageability to be specified within a single volume. Functions to create, start, and shut down a resource manager are also provided, along with other functions that facilitate resource manager usage.
摘要翻译：在单个逻辑卷上支持多个独立事务资源管理器的系统和方法，其中每个资源管理器是存储管理的一个单元。每个资源管理器独立地维护与包含在资源管理器的范围内的文件集合相关联的元数据，例如与资源管理器对应的子目录内的文件。通用架构允许数据库或其他实体通过资源管理器与事务文件系统卷进行集成，从而每个数据库都将其文件与事务性资源管理器独立关联，以使数据库操作不影响卷上的其他操作。拥有独立的资源管理器可以在单个卷中指定不同级别的性能，可靠性，功能可用性和可管理性。还提供了创建，启动和关闭资源管理器的功能，以及促进资源管理器使用的其他功能。
