摘要： Implementing synchronization among threads in a workflow. A memory area stores a plurality of work items in a scheduler queue. The work items are associated with an activity in the workflow, and each work item is associated with a thread. A processor is configured to assign a synchronization handle to each of the work items. The synchronization handle indicates a particular shared resource to be accessed by the work items. A token value is computed for each work item based on the assigned synchronization handle and the work items in a hierarchy in the activity. The work items are sorted in a synchronization queue based on the token value associated with each work item. The processor sequentially executes each of the sorted work items in the synchronization queue to serialize the access to the particular shared resource and effects a synchronous execution of the threads associated with the work items.

摘要： Asynchronous fault handling for a workflow. A state automaton for an activity in the workflow is defined. The state automaton includes at least an executing state, a faulting state, and a closed state and classifies an execution lifetime of the activity. The activity is defined to include work items and includes an execution hierarchy for the work items. Each work item includes an operation for executing a portion of the activity. Each work item is transitioned to the executing state. The included operation of transitioned work items is executed in the executing state. One or more of the transitioned work items are identified in response to the faulting event as a function of the execution hierarchy and the included operation. The faulting event is asynchronously handled by transitioning the one or more identified work items to the faulting state while executing the included operation of the remaining transitioned work items.

摘要： The present invention relates to systems and methods that facilitate pulling and/or receiving data from a client and posting the data for access by subscribing systems. The systems and methods include a message agent that generates a connection instance that can store connection-related information such as data conveyance state, data identification, and connection identification. Access to the connection instance can be provided to a machine, which can utilize the information to lock the connection and connection instance and begin pulling or receiving data from the client. As the machine pulls or receives data, the data can be published and the connection instance can be concurrently updated to reflect the present state of data conveyance. The information within the connection instance can be utilized to re-establish of severed connection, and to dynamically float the connection between machines to dynamically balance load, ensure reliability and recover from errors.

摘要： Optimistic concurrency is effectuated to manage constraints in a synchronization environment at multiple computing device endpoints in a consistent fashion without utilizing concentrated centralized constraint logic. Implemented data synchronization constraints that identify false violation scenarios may be automatically resolved without user intervention by using an etag system directed by a master component to assist computing device endpoints to maintain data synchronization among them. Data entries defining each file hierarchy component to be synched are generated and shared with the master component and each computing device endpoint in a synchronization environment. Individual computing device endpoints can use the data entries generated locally with those generated by other computing device endpoints to locally resolve identified false violation scenarios.
