Abstract: Using a common reference address when processing calls among a native ABI and a foreign ABI. Based on caller calling using a reference address, a lookup structure is used to determine whether the reference address is within a memory range storing native code (and that the callee is native) or a memory range not storing native code (and that the callee is foreign). Execution of the callee is initiated based on one of (i) when the caller is native and when the callee is foreign, calling the callee using the reference address within an emulator; (ii) when the caller is foreign and the callee is native, calling an entry thunk; (iii) when the caller is native and the callee is foreign, calling an exit thunk; or (iv) when the caller is native and the callee is native, directly calling the callee using the reference address.

In a data receiving process, the one or more applications obtain data on the paths through a system call, and further obtain data in a plurality of packets from at least one path. In a data sending process, the one or more applications distribute data to corresponding paths through a system call.

Abstract: Systems and methods for generating asynchronous application programming interface (API) documents are generally described. In various examples, a metadata discovery request may be sent to a message broker. A list of topics may be received from the message broker. First metadata related to a first topic of the list of topics may be received from the message broker. A first message may be received from the message broker, where the first message pertains to the first topic. A first schema may be determined using the first message pertaining to the first topic. The first schema may include data describing content of the first message and organization of the content of the first message. An asynchronous API document may be generated based at least in part on the first schema and the first metadata.

Abstract: In an embodiment, an operating system for a computer system includes a kernel that assigns code sequences to execute on various processors. The kernel itself may execute on a processor as well. Specifically, in one embodiment, the kernel may execute on a processor with a relatively low instructions per clock (IPC) design. At least a portion of other processors in the system may have higher IPC designs, and processors with higher IPC designs may be used to execute some of the code sequences. A given code sequence executing on a processor may queue multiple messages to other code sequences, which the kernel may asynchronously read and schedule the targeted code sequences for execution in response to the messages. Rather than synchronously preparing a message and making a call to send the message, the executing code sequences may continue executing and queuing messages until the code has completed or is in need of a result from one of the messages.

Abstract: The present disclosure relates to controlling communication between various applications or integrating various applications using interaction patterns. Interaction pattern data, which defines multiple roles for an interaction pattern is generated. Each role is associated with a transaction and is a source or target of a transaction. A transaction is performed using an application programming interface (API). A role can be a provider, or a consumer of the API based on whether the role is a source or target of the transaction. Application conformance data, which defines a set of roles implemented by the application is generated. An application is permitted to invoke an API of another application, if the application implements a first role and the other application implements a second role, and the first role and the second role are a source and target, respectively, of a transaction performed using the API.

Abstract: Some embodiments provide a method for distributing a set of parameters associated with policies for authorizing Application Programming Interface (API) calls to an application. For a previously stored hierarchical first document that comprises a first set of elements in a first hierarchical structure, the method receives a hierarchical update second document that comprises a second set of elements in a second hierarchical structure corresponding to the first hierarchical structure, wherein at least a subset of elements in the first and the second documents correspond to the set of parameters for evaluating API calls. The method receives a first set of hash values for elements of the first document that are not specified in the second document, and generates a second set of hash values for a set of elements specified in the second document. The method generates an overall hash for the second document by using the received first set of hash values and the generated second set of hash values.

Abstract: A set of consumers of a producer-consumer system includes a main consumer subset and a backstop consumer subset. A plurality of updates to message processing information are deployed to the set of consumers. Each update of the plurality of updates is first deployed to the backstop consumer sub-set and is subsequently deployed to the main consumer subset. The main consumer subset may obtain messages from producers and attempt to process the messages. By contrast, the backstop consumer subset may obtain messages only after a failed processing attempt by the main consumers. Upon obtaining a message, a main consumer may process the message successfully or may fail processing and provide the message for processing by a backstop consumer, which may be more up to date than the main consumer.

The method includes: receiving, by a first entity, an authorization revocation request message from a second entity, where the authorization revocation request message carries an identifier of an application programming interface (API) invocation entity; and sending, by the first entity, an authorization revocation response message to the second entity based on the authorization revocation request message.

Abstract: A system can host APIs for a plurality of different tenants and receive requests from many different client devices. As requests are received, an associated tenant can be identified, and a router can determine if a container instance is available to service the request. A container instance may be an empty container instance including an internal endpoint, a Web server, and a runtime environment. An empty container instance can be unassociated with a particular tenant. To associate a container instance with a tenant, a data store, such as a key-value data store can retrieve configuration files that turn the agnostic container instance into a container instance that is associated with particular tenant and includes configuration code to perform the requisite API functions. The pool of empty and populated containers can be managed efficiently.
