    摘要: Computing responses to semantic queries. A method includes accessing a plurality of objects that represent source code for an input program. The source code is transformed into a plurality of immutable objects that are structured such that the immutable objects can be used to derive any response as defined by the semantic rules about the source code. A query is received from a requestor requesting a semantic characteristic of the input program. The semantic characteristic is calculated. The semantic characteristic is returned to the requestor. The semantic characteristic is cached in a cache. Information describing a dependency between the cached semantic characteristic and one or more of the objects in the plurality of objects is stored.

    摘要: A signaling system of the present invention provides a synchronized approach to delivering, reporting, and/or otherwise processing status changes in a software dependency chain. In a first phase, the signaling system identifies all dependencies between software components, and further sets a binary indicator of each node in a first representation. After identifying any changes in a source node, the system (e.g., a value is updated), the system updates each binary indicator to a second setting. In a second phase, the system initiates all listeners in the dependency chain in an essentially progressive order from source node, to intermediate node, and end-node, etc. Once all listeners have had a chance to perform one or more processes based on the updated value, the system can discard the dependency graph, allowing a new dependency graph to be built for subsequent value changes.

    摘要: A transaction manager virtualization layer is provided for supporting multiple active transaction managers in a cluster or node. By virtualizing the transaction managers, applications and services are enabled to migrate across cluster nodes or even outside a cluster that includes relevant recovery mechanisms for transactions that are not completed at the time of migration. Multiple implementations of a transaction manager may be enabled to run side-by-side in a node or cluster allowing a rolling upgrade of transaction managers in clusters.

    摘要: An efficient, logical and expressive type system supports the combination of refinement types and type membership expressions, as well as a top type that encompasses all valid values as members. Various embodiments verify the validity of subtyping relationships by translating to first-order logic, and invoking a general-purpose theorem prover with the first-order logic as input. In contrast to treating formulas as types, types are translated into formulas of standard first-order logic. Moreover, to represent data structures of the programming language as first-order logic, universal and existential quantifiers of first-order logic, and function symbols in terms, are exploited. Data intensive applications can be generated, verified, and deployed with greater speed and scale.

    摘要: Minimizing transaction managers. A method that may be practiced in a commit tree topology including a plurality of transaction managers to manage transactions. The transactions include a set of operations that are all performed if a transaction is completed or all aborted if a transaction is not completed. The transaction managers store transaction result information to allow recovery of a transaction in case of system failure. The method includes acts for minimizing storage overhead by minimizing the number of transaction managers used to coordinate transactions. The method includes identifying a set of transaction managers. A first transaction manager is selected from among the set of transaction managers. A second transaction manager is identified from among the set of transaction managers that is always available when the first transaction manager is available. Messages are redirected from a subordinate associated with the first transaction manager to the second transaction manager.

    摘要: An efficient, logical and expressive type system is provided for flexibly defining types of a declarative programming language so that efficient and structurally compact data intensive applications can be generated. The type system supports the combination of refinement types and type membership expressions, as well as a top type that encompasses all valid values as members. With the type system, types can be expressed as intersections and/or unions of other types. Thus, types can be efficiently represented for a full range of types of data as may be found in real world data stores.
