Abstract

The invention discloses a method for cancelling time-consuming operation and blocking asynchronous conversion. The method comprises the following steps: creating a time-consuming operation thread; establishing a two-state semaphore for the time-consuming operation thread; enabling any thread to modify the two-state model quantity state into a signal so as to send a cancel request; and enabling the time-consuming operation thread to detect cancel by monitoring or querying a two-state semaphore state. Meanwhile, any blocking function can be converted into an asynchronous function or a UI blocking function for use. According to the method and system for cancelling time-consuming operation and blocking asynchronous conversion, the cancelling request and the blocking asynchronous conversion have business independence. The cancel request is sent to the thread executing the time-consuming operation only by using a uniform interface, and a special cancel interface does not need to be provided for different services, objects and operations. And the time-consuming operation can be realized only by providing a blocking interface instead of asynchronous and UI blocking interfaces.

Description

technical field [0001] The invention relates to thread processing technology, in particular to a method and system for canceling time-consuming operations and blocking asynchronous conversion. Background technique [0002] A large number of time-consuming operations are involved in the software, such as device IO, communication IO, and large calculations. These operations take a certain amount of time, and the completion time depends on factors such as system and network conditions, and has certain uncertainties. GUI SDK generally works in single-threaded mode, such as Windows GUI, Android GUI, QT GUI, etc. In a GUI App (graphical user interface application), the UI thread (the thread that processes the GUI) is responsible for monitoring and distributing UI messages (GUI messages), so that the GUI can accept user interface input. Therefore, the UI thread cannot directly perform time-consuming operations, otherwise the user's input will not be distributed and processed by t...
