摘要： A transactional file system wherein multiple file system operations may be performed as a transaction. An application specifies that file system-related operations are to be handled as a transaction, and the application 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. Logging and recovery are also facilitated by logging page data separate from the main log with a unique signature that enables the log to determine whether a page was fully flushed to disk prior to a system crash.

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 transactional file system performs multiple file system operations as part of a user-level transaction. An application specifies that operations should be handled as part of a transaction, and the application is given a file handle associated with the transaction context. Operations are managed consistent with transactional behavior and data isolation is provided with multiple versions of a file and by tracking copies of pages that have changed. Transactional readers do not receive changes to a file made by transactional writers, until the transactional writer commits the transaction and the reader reopens the file. Logging and recovery are also facilitated by logging page data separate from the main log, with a unique signature that enables the log to determine whether a page was fully flushed to disk prior to a system crash. Namespace isolation is also provided until a transaction commits via isolation directories.

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.
