20140188790 | GLOBALLY UNIQUE IDENTIFIERS IN AN ONLINE CONTENT MANAGEMENT SYSTEM - Systems, methods, and computer-readable storage media for implementing globally unique identifiers (GUIDs) in a multi-user network-based content management environment, from the perspective of a server creating a GUID for a content item, and serving requests based on the GUID. A content management system can identify a content item at a location within the data storage. Each user of the content management system can be associated with a respective user account having an amount of storage space within the storage environment. The content management system can model a user account as a collection of content item objects and globally unique identifiers that are independent of a directory-based hierarchy of content items. | 07-03-2014 |
20140188868 | PREDICTIVE MODELS OF FILE ACCESS PATTERNS BY APPLICATION AND FILE TYPE - The speed at which files can be accessed from a remote location is increased by predicting the file access pattern based on a predictive model. The file access pattern describes the order in which blocks of data for a given file type are read by a given application. From aggregated data across many file accesses, one or more predictive models of access patterns can be built. A predictive model takes as input the application requesting the file access and the file type being requested, and outputs information describing an order of data blocks for transmitting the file to the requesting application. Accordingly, when a server receives a request for a file from an application, the server uses the predictive model to determine the order that the application is most likely to use the data blocks of the file. The data is then transmitted in that order to the client device. | 07-03-2014 |
20140189051 | MAINTAINING CONCURRENCY AND CONSISTENCY OF GLOBALLY UNIQUE IDENTIFIERS - Systems, methods, and computer-readable storage media for ensuring data consistency and concurrency for globally unique identifiers (GUIDs) and associated content items via locking. A content management system configured to practice the method can receive, from a client device, a request to perform a content item operation in a storage environment that affects a GUID. Then the content management system can acquire a first mutex for a namespace associated with the content item operation, such as an application-level lock, and acquire a second mutex for the GUID, such as a row-level lock in a database table. After acquiring the locks, the content management system can perform the content item operation according the request, and update the GUID based on the content item operation. Then the content management system can release the mutexes and provide a confirmation to the client device in response to the request. | 07-03-2014 |
20140189118 | MAINTAINING CONSISTENT GLOBALLY UNIQUE IDENTIFIERS VIA AN ASYNCHRONOUS INTERFACE - Systems, methods, and computer-readable storage media for maintaining consistent globally unique identifiers (GUIDs) for content items accessible via an asynchronous interface in a multi-user network-based content management environment (storage environment). The example content management system can make a content item within a data storage available to an authorized user via the asynchronous interface, and receive, from a client device, content item change information derived from data generated by an operating system function at the client device. Then the content management system can analyze the content item change information to determine a corresponding action at the content management system, and implement the corresponding action on the server side. The content management system can optionally provide a confirmation of the corresponding action to the client device. | 07-03-2014 |
20140189355 | ENCRYPTING GLOBALLY UNIQUE IDENTIFIERS AT COMMUNICATION BOUNDARIES - Systems, methods, and computer-readable storage media for encrypting communications containing or referencing globally unique identifiers to prevent unauthorized access to content item data, such as through spoofing or ancillary information leakage. An example system configured to practice the method identifies a communication, between a storage environment and a client device, associated with a globally unique identifier for a content item stored in at least one of the storage environment and the client device. The content item can be addressable via a globally unique identifier. Prior to transmitting the communication, the system can encrypt a portion of the communication containing the globally unique identifier using an encryption key based on a client-specific key and a secret version-specific key to yield an encrypted communication, and transmit the encrypted communication to the client device. | 07-03-2014 |
20140279842 | INFERRING A SEQUENCE OF EDITING OPERATIONS TO FACILITATE MERGING VERSIONS OF A SHARED DOCUMENT - The disclosed embodiments relate to a system that infers a sequence of editing operations that were applied to a document to produce an updated version of the document. During operation, the system computes a minimum edit distance between the document and the updated version of the document. During this process, the system associates a block cost with each contiguous block of characters that is changed by an editing operation and also a character cost with each character that is changed. Next, the system uses information stored during the computation to determine the sequence of editing operations which were used to achieve the minimum edit distance. The system communicates the sequence of editing operations to a remote computing device, wherein the remote computing device uses an operational transformation technique to transform the sequence of editing operations before applying the transformed sequence of editing operations to a remote version of the document. | 09-18-2014 |
20140280463 | IMPLEMENTING A CONSISTENT ORDERING OF OPERATIONS IN COLLABORATIVE EDITING OF SHARED CONTENT ITEMS - Systems, methods, and computer-readable storage media for ordering editing operations in collaborative editing of shared content items. The content management system can receive an edit operation from a first client for a content item that is shared for collaborative editing between the first client and a second client. In response to receiving the operation, the system can send an update to the first client including a previous operation received from the second client prior to receiving the operation from the first client, wherein the update can instruct the first client to perform a transform operation to transform a parameter of the operation according to an effect of the previous operation received from the second client. The system can then receive a result of the transform operation from the first client and update the shared content item based on the previous operation and the result of the transform operation. | 09-18-2014 |
