Abstract: Systems and methods for maintaining and updating file system shadows by a synchronization client of a cloud-based platform. In some embodiments, an executor of the synchronization client can execute an action on an item in the local file system which changes the state of the item from an old state to a new state. The synchronization client updates the file system shadows with the new state of the item via an interface to facilitate generation of a synchronization event for the change to the item, that would otherwise go undetected if the change to the item was immediately reversed. In some embodiments, methods for providing shadow consistency and enhancing concurrent access to shadows are implemented by the synchronization client in maintaining and updating the file system shadows.

Abstract: Techniques for monitoring local and/or remote file systems by a synchronization component (e.g., client/server) of a cloud-based platform are disclosed. In some embodiments, a method of building synchronization events by a synchronization component (e.g., a synchronization server/client) includes obtaining a set of items that have been changed and their new states and retrieving last known states of the set of items that are stored in a reference snapshot inside a filesystem scanner. The method further includes generating differences between the new states and the last known states of the set of items as item changes and utilizing information provided by the item changes to translate the item changes into synchronization events for execution on the opposing file system. A method of handling failed synchronization events by a synchronization component of the cloud-based platform by collapsing a subsequent event with the failed synchronization event is also disclosed.

Abstract: Techniques are disclosed for implementing repository redundancy in a system which incrementally updates remote clients with events that occurred in a cloud-enabled platform. In one embodiment, a method comprises comparing a local timestamp of an event with a remote timestamp of the event. The event is to be stored in a queue in a repository cluster to be read by a remote client. The method further comprises updating the local timestamp of the event if the comparing indicates that the remote timestamp is more recent than the local timestamp. Among other advantages, embodiments disclosed herein ensure that no event in an action log is missed or skipped by any of remote clients in a distributed action log framework system during a switchover from an active but failed server to a backup server, and require zero or minimal down time during the switchover, thereby providing robustness and serviceability to such system.

Abstract: Techniques are disclosed for race condition handling in a system which incrementally updates clients with what occurred in a cloud-enabled platform. In one embodiment, a method comprises, in response to an event received at a synchronization client which indicates a modification to an item, comparing a sequence identifier of the item in the event with a current sequence identifier of the item. The sequence identifier of the item can be numeric and can monotonically increase as a state of the item changes. The method further comprises, if the sequence identifier in the event is larger than the current sequence identifier of the item, determining a difference between the item's state as represented in the event and a current state of the item; and, based on the difference, generating at least one synchronization step to update the current state of the item to the item's state as represented in the event.
