Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for re-associating content items of a user account of a content management system on a computing device relinked to the content management system. The systems, methods, and non-transitory computer-readable storage media can include the content management system receiving a request to relink the computing device with a user account of the content management system. The systems, methods, and non-transitory computer-readable storage media can also include determining a local content item of the client device corresponds to at least one revision of a plurality of revisions of a content item of the user account, wherein the content item is currently removed from the user account. Finally, the systems, methods, and non-transitory computer-readable storage media can cause the client device to delete the local content item.

Abstract: A client application of a content management system provides instructions for synchronizing content items and placeholder items using a local file journal and updated file journal. The client application compares entries in the updated file journal to entries in the local file journal to determine modifications to make to content items or placeholder items stored in a shared content storage directory on the client device. Based on the result of the comparison, the client application replaces placeholder items with content items or replaces content items with placeholder items.

Abstract: 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.

Abstract: The disclosed technology relates to a system configured to identify a first operation in a first set of operations configured to converge a server state and a file system state, wherein the first operation is not in a second set of operations generated in response to an change to at least one of the server state and the file system state. The system is further configured to cancel the first operation, identify a second operation in both the first set of operations and the second set of operations, and initiate execution of the second operation concurrently with the canceling of the first operation.

Abstract: A content management system synchronizes content items across client computing systems connected by a network. If a storage allocation for shared content items on a client device is exceeded by the request to add or edit a content item such that it is enlarged, a client application or the host of content management system selects content items to remove from residence on the client device but keep remotely on content management system. Upon removal of the selected content items, the client application creates shadow items, representing the content item but only containing the metadata of the content item. This creates sufficient space while maintaining user access to all synchronized shared content items. Entries in a file journal may be used to track and manage whether a stored item is a content item or a shadow item.

Abstract: A client can allocate and reassociate unique identifiers to local content items associated with an account at a content management system, and use the unique identifiers to commit operations for the content items on the content management system. For example, a client can create a content item and determine the content item does not have an identifier from the content management system. The client obtains an identifier for the content item and asks the content management system to verify a uniqueness of the identifier. When the identifier is unique, the client adds a node corresponding to the content item to a local tree representing a state at the client of content items associated with the account, and uploads the content item with the identifier to the content management system. When the identifier is not unique, the client obtains a new identifier for the content item.
