example 2

[0043] In this embodiment, the query interface is an interface function, such as the interface function get_hotpatch_info(). Obtain the hotpatch information data structure hotpatch_info instances 2021, 2022, 2023, 2024 by calling the interface function get_hotpatch_info().

[0044] When a plurality of hotpatch information data structure hotpatch_info instances 2021, 2022, 2023, and 2024 corresponding to the hotpatch function are connected with the linked list 200, as an implementation mode, by calling the interface function get_hotpatch_info(), the interface function get_hotpatch_info() returns the linked list header 201, and then traverse the linked list 200 through the header 201 to obtain hot patch information.

[0045] Then, as in step S102, it is judged whether the hot patch is loaded. Loading refers to loading the compiled hot patch into the virtual address space of the target process. In this embodiment, it is determined whether the hot patch is loaded by searching fo...

Abstract

The invention provides a hot patch information inquiring method and device. The hot patch information inquiring method comprises the steps that step S101: when a hot patch is pre-generated, the hot patch information data structure is defined in the hot patch, and an inquiring interface for reading the hot patch information data structure instance is generated in the hot patch; step S102: whether the hot patch is loaded is judged, the step S103 is performed if the judgment result is yes, or hot patch information inquiring is ended; step S103: the address of the inquiring interface is computed; and step S104: the inquiring interface is called according to the address of the inquiring interface, and the hot patch information data structure instance is acquired through the inquiring interface so as to acquire the hot patch information. The hot patch information data structure is defined in the hot patch and the inquiring interface is generated, and the inquiring interface is called to read the hot patch information data structure instance so as to acquire the hot patch information without additional arrangement of configuration files.

Description

technical field [0001] The invention relates to the field of software update, in particular to a hot patch information query method and device. Background technique [0002] With the rapid development of computing technology in recent years, the replacement speed of computer products has also increased. At present, in the software development process, it is inevitable that there are some loopholes in software design or new needs of users for the software. In order not to affect the use of the software, the software is generally repaired or updated in the form of hot patches. Make repairs or updates to the software without discontinuing the software. The process hot patch technology is a technology for loading a hot patch to a running process without interrupting the running of the process. The processing method of the process hot patch technology is basically based on the function unit, that is, the process can be repaired or updated by repairing the functions that have vu...
