A method of integrating an Xt Intrinsics based toolkit with a JAVA application. The application includes a process thread that implements an X event loop and an application thread that suspends execution of the event loop to allow a call to be made through the JAVA Native Interface to a toolkit or a widget to cause something to be displayed. The application thread includes a write socket to communicate a token to a read socket of the event loop, and performs a blocking read suspending the thread. The event loop returns an acknowledgment token via a write socket to a read socket of the thread that unblocks its blocking read and the event loop invokes its own blocking read suspending its execution. The file descriptor function, XtAppAddInput, preferably, is used to read the token and to set the blocking read. After a toolkit call is made, a token is sent from a second write socket of the thread to a second read socket of the event loop that unblocks its blocking read resuming the event loop. JAVA multithreading support services, such as JAVA's wait and notifyAll methods, are employed in multithreaded applications to ensure that only one thread at a time can make a call. Use of a separate Intrinsics application context to service the event loop is employed, windows are managed in separate hierarchies associated with each application context, and a special JAVA Canvas manages native windows transparent to the programmer.

At least one embodiment of the present application can implement hot upgrade of processes.

A automation system, a computer and method for communicating includes exchanging data, between a first computer, a second computer and at least one automation device over a wide area network via an application-specific protocol, wherein one of the computers has a local network connection to the automation device, the application-specific protocol has an application layer, and the first and second computers execute respective first and second automation programs such that a transparent connection is provided for the automation programs and their application-specific protocol beyond local network boundaries which can be it efficiently, where signaling functions from lower communication layers that are missing are simulated by introducing event loops on both sides of the communication.

Methods and systems for pre-fetching operations include executing event callbacks in an event loop using a processor until execution stops on a polling request. A path walk is performed on future events in the event loop until the polling request returns to pre-fetch information for the future events into a processor cache associated with the processor. Execution of the event callbacks in the event loop is resumed after the polling request returns.

The present disclosure relates to a form modification method, device, storage medium and electronic equipment. The method includes: generating a first virtual form model of the current form according to the original form model of the current form, and the first virtual form model is consistent with the original form model ; When the first operation on the current form is detected, put the second virtual form model obtained by duplicating the first virtual form model into the current event cycle, so that all the events that occur in the event cycle and target the current form The modification operations all act on the second virtual form model; according to the comparison result between the third virtual form model and the first virtual form model obtained after the end of the event loop, the original form model is modified. The virtual form model can be modified multiple times within an event loop, so that the redrawing of the form does not need to be triggered every time the form model is modified, so unnecessary resource consumption can be avoided and performance loss can be reduced.

The present application provides a URL data mining method and system. The data mined by the method can be applied to the upgrade of Internet behavior management equipment, including: obtaining URL data, cutting the URL data, and adding them to the coroutine event loop in turn; by running the coroutine The event cycle visits the URL address, and receives the request response fed back by the URL address server, and obtains the response data according to the request response; then checks whether the response data contains JS jump code; if it contains JS jump code, parses the JS jump code, and obtains the Orient the URL address, and receive the response data again; finally, store the URL address and the response data in a file according to the preset format. The method transforms passive acquisition of URL data into active acquisition, and reduces thread and process blockage caused by request response timeout waiting through coroutine events, thereby improving data mining efficiency.

The invention discloses a dynamic token-based multi-path source node location privacy protection routing method, which is characterized by comprising the following steps: 1) defining a network structure; 2) defining an attacker model; 3) token link transmission; 4) Event loop and interference loop transmission path; 5) Multi-path transmission. This method makes it difficult for attackers to backtrack to the source node, can prolong and resist backtracking attacks, increase the security time of the network, and realize the privacy protection of the source node location. In the loop transmission stage, the participation of some nodes can save network energy. power consumption and improve network life.

The invention relates to the field based on IPv6, and in particular relates to a design method of an industrial Internet edge gateway supporting high concurrent Web access, including the real-time collection of edge device data by an edge computing node in an IPv6 environment; The collected data is uploaded to the gateway Sqlite database; the size of the thread pool is set according to the time proportion of the current intensive computing, so that each thread in the thread pool is an event loop, that is, a thread is an event loop bound to a thread and an event, and an event It is a task request; uses the Reactor reaction model to process the client's connection request and uses the main thread to distribute it to sub-threads; uses Round Robin to control the thread load in the thread pool to achieve a balanced state; uses the edge-triggered model-based The epoll IO multiplexing mechanism monitors events; the present invention can support high concurrent access of clients even in edge gateways with limited resources, which facilitates real-time management of edge devices by users.

This class encapsulates uniform member variables and member methods for different operating systems; logically sorts each device, designs Hash storage methods, and stores data efficiently and accurately. It can establish Tcp connection to thousands of data terminals, maintain the status, take data and issue control commands, and realize high concurrent communication in the Proactor mode of the interface communication layer of the landscape lighting system.

A computer implemented method for processing tasks is disclosed. The method includes invoking a timed iterator, during an event loop pass, without spawning a new thread, wherein the invoking includes passing a task list and a timeout constraint to the timed iterator. The method further includes executing one or more tasks in the task list for a period of time as specified in the timeout constraint, and relinquishing program control to a caller after the period of time.

The purpose of this application is to provide a website server event processing technology, by running the main thread, after the main thread creates a coroutine based on the processing request of the event, then suspend the main thread and switch to the coroutine process; run the coroutine, create a communication channel by the coroutine, and hand over the main business logic of the event to the worker thread pool for processing, then suspend the coroutine and switch to the main thread; again Run the main thread, continue to process the event loop by the main thread, until the message that the worker thread pool sent by the communication channel is obtained, suspend the main thread and switch to the coroutine; run again In the coroutine, the secondary business logic of the event is processed by the coroutine, and after the processing is completed, the coroutine is terminated and switched back to the main thread. As a result, other requests that are being processed in parallel by the main thread are processed in a timely manner, reducing the average response time of the system.
