Abstract
Implementations are provided herein for sending event notifications based on modifications to files and/or directories. When a file is read, modified or changed under the conditions for a registered event notification, a consistency point can be established. An impact list can then be determined based on the target. It can then be determined whether the version of event caches associated with the files and folders identified in the impact list match a global event cache version determined at the time of the consistency point. If the event caches are an old version, the system call can be restarted, and the event caches can be rebuilt to the current version. If the event caches of the impact list are current, the file system operation can be performed, and notifications can be sent based on the set of listeners identified within the current set of event caches.
