Technologies for implementing customized behaviors for content items are provided. An example method can include receiving, from a user account registered with a content management system, a request to access a content item managed by the content management system for the user account, the content item having one or more behaviors configured for an attribute associated with the content item and/or the content item associated with the attribute; obtaining, from a representation of a remote state of content items associated with the user account, metadata defining the attribute associated with the content item; based on the metadata, determining the one or more behaviors configured for the attribute and/or the content item associated with the attribute; and applying the one or more behaviors to the content item.

Per-node metadata for custom node behaviors across platforms

The disclosed technology relates to a system configured to receive operations data from a content management system, wherein the operations data comprises a log of operations, execute the log of operations, and update, based on execution of the log of operations, a remote tree representing a server state for content items stored on the content management system.

Updating a remote tree for a client synchronization service

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

Content management client synchronization service

The disclosed technology relates to a system configured to receive, from a content management system, an initial portion of a log of operations for a target namespace, build a subtree for the target namespace based on the initial portion of the log of operations, and mount the subtree for the target namespace at a mount location of a remote tree representing a server state for content items stored on the content management system.

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.

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.

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.
