Publication number: 20090228429Abstract: The claimed subject matter provides a system and/or a method that extends transactional guarantees to unstructured data in a file system. A database engine, configured to retain structured data, can reserve a portion of the file system to store unstructured data to be managed by the database engine. A kernel component can associate a transaction with at least one stream that corresponds to the reserved portion of the file system. The association enables transaction based access to the reserved portion of the file system managed by the database engine.Type: ApplicationFiled: March 5, 2008Publication date: September 10, 2009Applicant: MICROSOFT CORPORATIONInventors: Cristian Diaconu, Michael J.

Patent number: 7577960Abstract: The invention provides a system and method for managing cached objects using notification bonds. A server is configured to manage original objects. A client creates cached objects from the original objects and establishes notification bonds with the server. Each notification bond enables the client to obtain a notification from the server in response to an object related event associated with an original object. The client uses the data in the notification to update the cache object corresponding to the original object without synchronizing other cache objects.Type: GrantFiled: June 19, 2003Date of Patent: August 18, 2009Assignee: Microsoft CorporationInventors: David Cappers Steere, Rohan Kumar, Yun Lin, Danilo D'Amico Almeida, Shishir Purushottam Pardikar

Patent number: 7437429Abstract: Access to WebDAV (Distributed Authoring and Versioning) servers is provided in a manner that is essentially transparent to applications. A WebDAV redirector and related components support file system I/O requests and network requests directed to WebDAV servers identified by URI (Universal Resource Identifier) names, or by a drive may be mapped to a WebDAV share. An application's create or open I/O requests directed to a WebDAV server are detected, and result in a local copy of the file being downloaded and cached for local access. When closed, the local file is uploaded to the WebDAV server. Network-related requests such as for browsing that are directed to a WebDAV server are also handled transparently. WebDAV files may be locally encrypted and decrypted at the file system level, transparent to applications and the WebDAV server, via an encrypting file system that performs local encryption and decryption at the local file system level.Type: GrantFiled: January 17, 2002Date of Patent: October 14, 2008Assignee: Microsoft CorporationInventors: Shishir Pardikar, Rohan Kumar, Yun Lin, Praerit Garg, Jianrong Gu

Patent number: 7349943Abstract: A system and method that automatically and transparently handle client-side caching of network file data, independent of any remote file handling protocol. A protocol-independent client-side caching mechanism is inserted as a service that handles file-related requests directed to a network, and attempts to satisfy the requests via a client-side caching persistent store. By way of pre-process and post-process calls on a file create request, the caching mechanism creates file-related data structures, and overwrites the information in those structures that a buffering service uses to call back to a network redirector, whereby the client-side caching mechanism inserts itself into the communication flow between the network redirector and the buffering service.Type: GrantFiled: March 12, 2003Date of Patent: March 25, 2008Assignee: Microsoft CorporationInventors: Yun Lin, Navjot Virk, Shishir Pardikar, Rohan Kumar

Publication number: 20070239720Abstract: Systems and methods that create a virtual name space of Universal Naming Convention (UNC) over a local file system (e.g., drive letter based names), via employing a UNC provider and filter arrangement that changes a name in the file object to reparse it to a volume where the local file exists. A name in the file object is changed to a local name (e.g., morphed name); subsequently reparsed and forwarded to a Name Space Owner component (NSO). As such, a request can originate from a UNC stack and reparsed on the local stack. The name space is presented to an application in UNC format, while the underlying file write occur in the file system.Type: ApplicationFiled: April 7, 2006Publication date: October 11, 2007Applicant: Microsoft CorporationInventors: Rohan Kumar, Neal Christiansen, Eileen Brown, Garret Buban

Publication number: 20070214190Abstract: A file stream exchange system and method are provided. The system can be employed, for example, with a storage system that supports transactions as a primary mechanism and employs a rich type system. The system provides a mechanism for the storage system to provide reliable updates to file streams while preserving the common criteria for security. The system employs a unique way of remapping the file-streams associated with the file-backed items that eliminates the need for copying over basic attributes, security information and timestamps etc. Significantly, the system does not rename the files involved in the operation nor does the system rely on attribute tunneling to copy over any subset of attributes for the completion of the task. The system includes a replace stream component which is a kernel mode mechanism that allows transactional exchange of stream data of two file-backed items without violating the common criteria for security.Type: ApplicationFiled: February 17, 2006Publication date: September 13, 2007Applicant: Microsoft CorporationInventors: Mahesh Sreenivas, Arkadi Brjazovski, Stefan Steiner, Rohan Kumar, Sameet Agarwal
