摘要： A set of application programming interfaces (“APIs”) is provided that enables an application to perform operations on multiple system resources as a single logical unit of work through a transaction. The application can then commit or roll back the entire group of changes as a single unit in a coordinated manner. The APIs expose functions and methods that take a reference to a transaction context, such as a handle, name, or pointer, as one of their parameters so that the application can manipulate the resource as a transacted operation. The transaction is bound to all created handles so that all operations on the resource using those handles are also transacted. In an illustrative example, the set of APIs are transacted name-based WIN32 APIs that take a transaction handle. The transacted APIs expose transacted operations to the application for durable system resources in the OS kernel, including the NTFS file system (New Technology File System) and registry.
摘要翻译：提供了一组应用程序编程接口（“API”），使得应用程序可以通过事务将多个系统资源作为单个逻辑工作单元执行操作。然后，应用程序可以以协调的方式将整个更改组作为单个单元进行提交或回滚。 API公开了将事务上下文（例如句柄，名称或指针）引用为其参数之一的函数和方法，以便应用程序可以将该资源作为事务处理操作。事务绑定到所有创建的句柄，以便使用这些句柄的资源上的所有操作也被处理。在一个说明性的例子中，这组API是处理基于名称的WIN32 API，它采取事务处理。事务处理的API将处理的操作暴露给OS应用程序中的持久系统资源，包括NTFS文件系统（新技术文件系统）和注册表。

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： 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： Minimizing transaction managers. A method that may be practiced in a commit tree topology including a plurality of transaction managers to manage transactions. The transactions include a set of operations that are all performed if a transaction is completed or all aborted if a transaction is not completed. The transaction managers store transaction result information to allow recovery of a transaction in case of system failure. The method includes acts for minimizing storage overhead by minimizing the number of transaction managers used to coordinate transactions. The method includes identifying a set of transaction managers. A first transaction manager is selected from among the set of transaction managers. A second transaction manager is identified from among the set of transaction managers that is always available when the first transaction manager is available. Messages are redirected from a subordinate associated with the first transaction manager to the second transaction manager.

摘要： A security model is provided in a transactional logging infrastructure that is arranged as a protected subsystem built on an underlying secure file system. Files in the underlying file system used by virtual log streams are protected from direct user writes, and are written-to only through the protected subsystem that is brokered by a machine-wide principal so that virtual log files sharing the same multiplexed physical log are kept secure from each other. Log file handles and user- and kernel-mode objects are exposed to log clients through interfaces using consistent security semantics for both dedicated and virtual logs. Log clients are agnostic of the underlying secure file system and can only manipulate file system containers—abstract objects that implement the physical log and used to virtualize the file system by normalizing input/output operations—by using the interfaces brokered by the principal in the protected subsystem.

摘要： A transactional logging service is provided to user-mode and kernel-mode log clients by utilizing a marshalling area to buffer a set of log records that a log client assembles into a log stream. Disk I/O (input/output) functionality is then separately brokered using a kernel-mode address space for a single dedicated physical log, or virtual logs multiplexed to a single log, which is written to stable storage that contains log records from across all of the log streams. Physical log writes are handled by a shared log flush queue and physical log reads are provided by a file system cache that underlies the service. A multi-level cache hierarchy is utilized when a log client needs to access a log record. A series of caches are queried in order of increasing latency until the targeted log record is located. The target log record is only read from disk in the event that it missed at each cache in the hierarchy.
