Abstract: Techniques are provided for inofile management and access control list file handle parity. For example, operations targeting a first storage object of a first node are replicated to a second storage object of a second node. A size of an inofile maintained by the second node is increased if an inode number to be allocated by the replication operation is greater than a current size of the inofile. Access control list file handle parity is achieved by maintaining parity between inode number and generation number pairings of the first node and the second node.

Abstract: A technique for synchronizing a datum between a plurality of stores, wherein a version history is associated with the datum in each store. The version history has one or more entries, and each entry has an identifier and a value. The identifier identifies a store that has modified the datum, and indicates a number of modifications to the datum. When synchronizing the datum between stores, the version histories of the datum are compared to determine whether one version history is subordinate to another version history. The datum having the subordinate version history is then replaced with the datum having the dominant version history. Conflict resolution is required if the version histories are not identical, if the version histories do not have the same identifiers, and if one version history does not contain all of the identifiers with equal or greater values of those in the other version history.

Abstract: A content management system defines a synchronization application programming interface (API) used by applications executing on client devices to synchronize content items after the content items are changed. Functions of the API specify changes to the content items in terms of semantically-meaningful locations within the content items, rather than physical file locations. The content management system can represent the state of a content item in terms of change descriptors that reference the semantic locations of the API. The content management system can then distribute the change descriptors to the client devices, which refer to the semantic locations of the change descriptors when determining how to reconcile changes made by other client devices.
