Embodiment Construction

[0058]There are the following common asynchronous task implementation schemes: one is to create a thread for each task, so that other tasks can continue to run in the main thread, and in the message processing thread, waiting for the response of the message . The advantage of this scheme is that it is simple to implement, but the disadvantage is that each task needs to enable a separate thread, which consumes a lot of system resources when there are too many tasks. Another implementation scheme is to generate a device descriptor for each event, and then add the device descriptor to the system monitoring through the system's IO multiplexing technology to realize the notification of the response message. The advantage of this scheme is that a single thread can manage multiple events, but the disadvantage is that the implementation is complex, and different system implementations need to be adapted. In order to solve the problem of high system resource consumption, complex imple...

Abstract

The invention belongs to the technical field of asynchronous task processing, and particularly provides a cross-platform asynchronous message processing method and device, equipment and a storage medium, and the method comprises the following steps: when a message is sent, registering the message and an overtime processing function of the message into a time wheel timer, adding the message into a red-black tree, and setting a reference count to be increased; receiving a response message, and judging whether an overtime processing function of the message is called or not; if not, inquiring a red-black tree to judge whether the message exists or not; if yes, obtaining a specific object in the red-black tree for response processing; if not, discarding the response message, and reducing the reference count; if yes, judging that the response is overtime, deleting the message from the red-black tree, and removing the message from the timed task at the same time; and when the reference count value is zero, destroying the object. The objects are managed by introducing reference counts, and it is guaranteed that the objects can be correctly released.

Description

technical field [0001] The invention relates to the technical field of asynchronous task processing, in particular to a cross-platform asynchronous message processing method, device, device and storage medium. Background technique [0002] At present, the commonly used asynchronous task implementation schemes are as follows: [0003] One is to create a thread for each task, so that other tasks can continue to run in the main thread, and in the message processing thread, waiting for the response of the message. The advantage of this scheme is that it is simple to implement, but the disadvantage is that each task needs to enable a separate thread, which consumes a lot of system resources when there are too many tasks. [0004] Another implementation scheme is to generate a device descriptor for each event, and then add the device descriptor to the system monitoring through the system's IO multiplexing technology to realize the notification of the response message. The advant...
