Abstract: In a synchronization system, the present invention provides an improved user interface through which a user can view and manage settings associated with the user's account in the synchronization system. In the preferred embodiment, a column is displayed for each electronic device associated with the user's account in the synchronization system. In each column is a visual representation of items (e.g., folders) that are (1) backed up, remotely accessible and/or synchronized in the synchronization system and (2) located on the electronic device associated with such column. For each item that is synchronized across multiple devices, all the visual representations of such item in the columns are aligned across a single row in the interface. In the preferred embodiment, there is an arrow, or other visual indicator, between the visual representations of such items to indicate that the items are synchronized.

Abstract: The present technology pertains to synchronizing contents of a directory external to a synchronized directory by a content management system. The content management system is configured to synchronize only objects in the synchronized directory. Accordingly, the present technology creates an anchor object that represents the directory external to the synchronized directory within the synchronized directory. The anchor object includes special attributes that indicate to the synchronization client that the anchor object represents an external directory, and allows the contents of that directory to be synchronized directly to a server on the content management system without first storing the contents of the external directory on the hard drive of the client device.

Abstract: Systems and methods for snapshot isolation in a distributed storage system M are provided. In some examples, a method can include receiving a request for data from a data store comprising a plurality of storage nodes, the request comprising a key associated with the data and a request timestamp, identifying a storage node in the plurality of storage nodes from which to read the data based on the key and a mapping of keys to storage nodes, determining that the request is associated with a transaction comprising operations associated with at least one other storage node in the plurality of storage nodes, determining a status of the entry for the key in the key-value table based on a lookup of a transaction table using the transaction identifier, and providing the data when the status of the entry for the key indicates the data is ready to be read.

Abstract: The present technology can provide a mechanism for providing a team member transfer interface to an administrator user for transferring team member user accounts from one team to another and also a mechanism for transferring the team member user accounts, such as by switching an assignment of one or more user accounts from a first team to another in a single atomic action. The transferring of the team member user accounts may also depend on passing a set of validation checks that check for inconsistencies that could cause an error in the transfer, and also updating access and privileges associated with being members of certain teams.

Abstract: The present disclosure is directed toward systems, methods, and non-transitory computer readable media for generating contextual hubs for organizing and presenting web-accessible content from third-party sources. In particular, the systems described herein can organize and manage within a contextual hub. For instance, the disclosed systems may perform actions on tabs based on analyzing usage signals associated with the tabs. Furthermore, the disclosed systems can organize contextually related content within contextual hubs. The disclosed systems may also facilitate collaboration between users within a contextual hub by synchronizing interactions with content within a contextual hub.

Abstract: This disclosure generally covers systems and methods that identify relevant information for a user based on an object graph for documents and other files hosted by a document hosting system. In particular, certain embodiments of the disclosed systems and methods generate an object graph comprising interconnected nodes representing relationships among documents and other files on the document hosting system. Using the object graph, the disclosed systems and methods can identify relevant information and provide results or recommendations corresponding to that information based on a query or on user input, respectively.

Abstract: Resynchronization of folders shared among multiple client devices over a network is provided. Metadata and hash values stored on the client device are moved from a metadata database to a resynchronization database, and the data in the metadata database is deleted. Metadata is created for locally stored synchronized files. For each file, the created metadata is compared to the metadata stored in the resynchronization database. If the metadata matches, hash values are retrieved from the resynchronization database and stored with the created metadata in the metadata database. If the metadata does not match, hashes for the file are created and stored with the created metadata in the metadata database. A synchronization operation may be performed which consists of comparing the files stored on the client to the synchronized versions on a host server and updating or adding files that are not present or not up to date.

Abstract: Described embodiments enable device users sharing content items via a content management system to view and modify content items within native applications on their client devices. In various embodiments, a client application detects a save operation on a content item and prompts a user to provide a comment based on changes to the content item. User comments and metadata are provided to a content management system to create a historical log that provides a comprehensive summary of user interactions with a content item, including comments regarding content item changes, version information, and timestamps. The content management system provides the comments and other log contents to client applications associated with other users sharing the content item. The client applications use the comments and log information to provide notifications to the users regarding content item changes and comments by sharing users.

Abstract: An online photo management service that stores a collection of photos belonging to a user can send re-engagement messages to the user that can include photos automatically selected from the collection. The selection can be based on a scoring algorithm that rates the photos according to a set of attributes and computes a score based on the attributes and a set of weights. Based on user responses to re-engagement messages, the weights can be tuned to more reliably select photos likely to result in user re-engagement with the stored collection of photos.
