Method and device for monitoring blockage of main thread

Abstract

The invention discloses a method and a device for monitoring the blockage of a main thread, and relates to the technical field of computers. One specific implementation way of the method comprises thefollowing steps that: executing the following monitoring processes: adding a variable change function into the execution queue of the monitored main thread, wherein the variable change function is used for changing the preset value of a blockage judgment variable; and after a preset time interval, checking whether the value of the blockage judgment variable is changed or not, and when the value of the blockage judgment variable is not changed, determining that the main thread is subjected to blockage. By use of the implementation way, a main thread blockage situation during a whole application use period can be monitored, and user experience is not affected.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for monitoring main thread blocking. Background technique [0002] On a device running the iOS system, if the main thread is blocked during the running of the application, the iOS device will become unresponsive, and there will be an "app stuck" that does not respond to any screen updates or events such as touch, screen rotation, or key presses. Ton" phenomenon. This kind of situation in the application will have a very bad impact on the user experience, and may even cause the user to no longer use the application. Although the blocking of the main thread can lead to such serious consequences, any test and code inspection cannot guarantee that there are absolutely no problems in the application. Therefore, it is very important to establish a complete monitoring mechanism. [0003] In the absence of any additional monitoring mechanism, if the application fr...

Problems solved by technology

However, in the process of implementing the present invention, the inventor found that the watchdog plug-in can only monitor the blocking of several key functions triggered by events such as when the application starts or the background returns to the foreground, and cannot monitor the main line blocking in the entire life cycle of the application situation, and when blocking is detected, the watchdog plug-in will actively terminate the application, regardless of whether the application can return to normal later, which affects the user experience
