摘要： In some embodiments, a system for synchronizing content with client devices receives a request from a client device to synchronize operations pertaining to content items associated with a user account registered at the system. The request can include the operations and a cursor identifying a current position of the client in a journal of revisions on the system. Based on the operations, the system generates linearized operations associated with the content items. The linearized operations can include a respective operation derived for each of the content items from one or more of the operations. The system converts each respective operation in the linearized operations to a respective revision for the journal of revisions and, based on the cursor, determines whether the respective revision conflicts with revisions in the journal. When the respective revision does not conflict with revisions in the journal, the system adds the respective revision to the journal.

摘要： The disclosed technology relates to a system configured to compute a difference between a local tree data structure representing a file system state for content items associated with a user account on the computing system and a sync tree data structure representing a known synchronization state between a content management system and the computing system. The system is configured to generate, based on the difference, a set of operations that when performed update the content items stored on the content management system to converge a server state for content items associated the user account on the content management system and the file system state.

摘要： 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.

摘要： An interface of a content management system manages storage and access of content on the system. For example, after receiving, from a client, a request to download a content item, the interface determines whether the request includes a valid token. If so, the interface sends a content item request to a storage service, retrieves the content item, and sends the content item to the client. Otherwise, the interface sends an authorization request to an authorization service, an authentication request to an authentication service, and a content item request to the storage service. Based on the requests, the interface determines whether the content item is available in storage and whether the client is authorized to access the content item. When the content item is available in storage and the client is authorized to access the content item, the interface retrieves the content item and sends the content item to the client.

摘要： The disclosed technology relates to a system configured to identify at least one difference between a sync tree and at least one of a remote tree and a local tree. The sync tree represents a known synced state between a server state and a file system state, the remote tree represents the server state, and the local tree represents the file system state. The system may further generate, based on the at least one difference, a set of operations configured to converge the server state and the file system state and manage the execution of the set of operations.

摘要： In some embodiments, a synchronization system can synchronize symbolic links across multiple devices. For example, a content management system can receive, from a client device, one or more synchronization operations for synchronizing content items between the content management system and the client device. The content items can be content items associated with a user account registered at the content management system. The content management system can determine that the one or more synchronization operations include an operation for adding a content item to the user account, and that the content item is a symbolic link that includes a path to a target content item. The content management system can then synchronize the content item as a symbolic link.

摘要： The disclosed technology relates to a system configured to obtain a set of tree data structures including a remote tree representing a server state of content items associated with a user account on a content management system, a local tree representing a file system state of content items associated with the user account on a client device, and a sync tree representing a known sync state between the content management system and the client device. The system is configured to determine that the user account on the content management system includes at least one modification not synchronized to the client device by comparing the remote tree and the sync tree.
