Abstract: The disclosed technology relates to a system configured to receive a set of operations configured to converge a server state and a file system state, wherein the server state is for content items stored by a content management system and the file system state is for the content items stored on a client device. The system is further to detect a violation of a rule by an operation in the set of operations, identify resolution actions for the violation of the rule, and perform the resolution actions.

Abstract: In some embodiments, a client generates an operation modifying a local copy of a content item on a user account at a content management system and records an intent to commit the operation to a journal of revisions at the content management system. Based on the operation, the client sends to the content management system a first request to commit the operation at the journal, the first request including a cursor identifying a current position of the client in the journal. The client sends, to the content management system, a second request for a status of the commit and, based on the second request, determines whether the commit of the operation to the journal has succeeded. Based on whether the commit of the operation to the journal has succeeded, the client determines whether to update one or more tree data structures on the client and clear the intent to commit.

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: 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.

Abstract: The disclosed technology relates to a system configured to initialize, based on an initial file state, a client synchronization service configured to generate a final file state by performing a synchronization process on the initial file state. The system may further introduce at least one anomaly into the synchronization process, determine that the final file state is incorrectly synchronized, and store the initial file state for debugging the client synchronization service.

Abstract: A content management system can maintain the entirety of a user account's content library. As a default behavior, updates made to the content library when accessed from any client device authorized by the user account, including adding, modifying, and/or deleting content items, can be synchronized across all other authorized client devices. A user can opt out of the default behavior and specify, for each authorized client device, certain portions of the content library that the content management system should or should not synchronize.

Abstract: A client can allocate identifiers to local content items and ensure the identifiers are unique at a content management system. For example, a client can add a first content item at a first path and determine the first content item does not have a first unique identifier. The client can determine that a second content item at a second path was previously associated with the first path and determine that the first content item should inherit a second unique identifier from the second content item. The client can then assign the second unique identifier to the first content item and add a node representing the first content item to a local tree representing a local state of content items at the client, the node including the second unique identifier. The client can also upload the first content item with the second unique identifier to the content management system.
