In various aspects, a method, system and computer program product provides for concurrent changes to data of a document or a file by a plurality of users at a plurality of user devices. The documents or file may be rendered in JavaScript™ Object Notation (JSON) format. The documents may be patched or changed by employing new functional operations for applying metadata for elements of the arrays associated with the document or file, and to merge changes from made among the various users. The disclosure provides for maintaining and producing new versions of the document or the file, the changes controlled so that data of the arrays are merged atomically and the updates do not fail permitting simultaneous changes to the document or file by multiple users.

A document cooperation supporting apparatus for supporting a simultaneous edit of a document according to an exemplary embodiment of the present invention, and an operating method thereof sequentially transmit edit commands to each of the client terminals based on a reception sequence of the edit commands when the simultaneously generated edit commands are received from the plurality of client terminals, and performs an operational transformation on edit commands having later reception sequences to provide a cooperation environment enabling users to simultaneously edit the document.

The present technology pertains to a organization directory hosted by a synchronized content management system. The corporate directory can provide access to user accounts for all members of the organization to all content items in the organization directory on the respective file systems of the members' client devices. Members can reach any content item at the same path as other members relative to the organization directory root on their respective client device. In some embodiments novel access permissions are granted to maintain path consistency.

Embodiments of systems and methods as disclosed may provide a platform agnostic way to edit content within an enterprise. For example, a platform independent thin client editor may be provided such that this editor can be accessed by users at a variety of computing platforms across the distributed computer network of an enterprise, regardless of the platform from which the thin client editor is being accessed. Moreover, certain embodiments may provide a role based mechanism for controlling the editing of content. Embodiments of such a role based mechanism may allow one editor of a content item to designate a role associated with the content item so that only users associated with that role may be allowed to edit the content item or portion of the content item.

The present disclosure relates to a system and techniques for enabling data to be updated within a data store through concurrent operations. Embodiments of the system enables multiple client applications (e.g., implemented on a cloud platform) to update data concurrently. In some embodiments, operations may be determined to be either client-managed operations or service-managed operations. Client-managed operations may be performed by a client application, whereas the client application may pass service-managed operations to a service application. The service application may put each of the service-managed operations into a commit queue wherein each service-managed operation is committed only after the one put into the queue before it has been committed.

Remote data management, including: receiving, at a data storage service from a client device and via a remote data management application program interface (API), a data object; receiving, at the data storage service from the client device and via the remote data management API, a message including an indication of updated metadata and including an identification of a particular data object stored by the data storage service; and generating, in accordance with the updated metadata received from the client device, a modified data object that is a reduced version of the particular data object specified by the message received from the client device, wherein the reduced version of the particular data object is stored by the data storage service.

A computer-implemented method is provided for managing and sharing picture files. In one embodiment of the present invention, the method comprises providing a server platform and providing a datastore on the server platform for maintaining full resolution copies of the files shared between a plurality of sharing clients. A synchronization engine is provided on the server platform and is configured to send real-time updates to a plurality of sharing clients when at least one of the sharing clients updates or changes one of said files. A web interface may also be provided that allows a user to access files in the datastore through the use of a web browser.

Systems, methods, and computer-readable media for accelerating a transaction from a trusted source are provided. A method, according to one implementation, includes the step of obtaining a transaction to be processed in a network. The transaction may include one or more changes to data records stored in a database. The method also includes determining whether the transaction is obtained from a trusted source, where the trusted source may be predefined as a device that knows the state of components in the network. When the transaction is obtained from a trusted source, the method includes the step of committing the one or more changes prior to checking the validity of the one or more changes. When the transaction is not obtained from a trusted source, the method includes the step of checking the validity of the one or more changes prior to committing the one or more changes.

NUMA-aware reader-writer locks may leverage lock cohorting techniques that introduce a synthetic level into the lock hierarchy (e.g., one whose nodes do not correspond to the system topology). The synthetic level may include a global reader lock and a global writer lock. A writer thread may acquire a node-level writer lock, then the global writer lock, and then the top-level lock, after which it may access a critical section protected by the lock. The writer may release the lock (if an upper bound on consecutive writers has been met), or may pass the lock to another writer (on the same node or a different node, according to a fairness policy). A reader may acquire the global reader lock (whether or not node-level reader locks are present), and then the top-level lock. However, readers may only hold these locks long enough to increment reader counts associated with them.
