In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first," "second," "third," "fourth," and the like in the description and claims of this application and in the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may include other steps or elements not expressly listed.
Having described the technical solutions of the embodiments of the present invention, various non-limiting embodiments of the present application are described in detail below.
Referring to fig. 1, fig. 1 is a schematic flow chart of an automatic loading method for an upgrade file according to an embodiment of the present invention, where the embodiment of the present invention may include the following:
s101: and creating a monitoring process and an executing process.
The monitoring process can manage the operation of the process by using the process management module, is used for monitoring the change signal of the upgrade file and starts the execution process; the execution process can adopt a multithreading technology and is used for checking the state of the upgrade file, sending a state code and loading the modified upgrade file. The listening process and the executing process may be distinguished by using a preset environment variable, for example, by setting an environment variable ICS _ CHILD.
S102: and acquiring first change time of the upgrade file recorded when the monitoring process is started.
S103: when detecting that the change time of the current upgrade file is longer than the first change time, the execution process sets the state code of the upgrade file as a first identification code and sends the first identification code to the monitoring process, wherein the first identification code is used as a change signal of the current upgrade file.
The monitoring process executes the monitoring preparation work and starts the execution process, processes the change signal of the upgrade file, and correspondingly realizes the code and refers to the code 1. The preparation work of monitoring the monitoring process can include creating a temporary lock file, storing the temporary lock file in an environment variable and detecting whether the monitoring process is normal or not by executing the process; starting the execution process, setting ICS _ CHILD for running the execution process, and circularly checking the return state code of the execution process.
The update of the upgrade file may be based on the modification time of the file, for example, when the first modification time of the upgrade file recorded when the monitoring process is started is mtime, and when the modification time of the current upgrade file is greater than mtime, it may be determined that the current upgrade file has been modified, that is, the upgrade file has been updated.
Referring to the code 2, when the execution process checks that the upgrade software is changed, the state code is set as a first identification code, and the first identification code is pre-agreed and serves as a change signal of the current upgrade file. For example, the first identification code may be 3, and when the status code is 3, it indicates that the upgrade file is changed, and restarts the execution process. S104: and when the monitoring process receives the first identification code, restarting the execution process for loading and updating the upgrade file.
When the monitoring process receives the status code of the first identification code, the monitoring process proves that the current upgrade software is changed, so that the execution process is restarted, and at the moment, the execution process executes the software service thread, namely, automatically loads the upgrade file, such as a patch, and the implementation code refers to the code 3.
As can be seen from the above, the software service recognizes the change of the file upgrade and automatically performs the restart operation according to the data state of the software service itself. The success rate of automatic updating of the upgrade file can be improved.
It should be noted that the monitoring process circularly checks the return status code of the execution process, and when the status of the monitoring process is detected to be a preset default value, the monitoring process is dormant. I.e., S103-S104 are executed in a loop until sleep.
The preset default value may be 0, when the state of the monitoring process is the default value, it indicates that the current upgrade file is not changed, and when the state is not the default value, it indicates that the upgrade file is changed. The sleep time may be preset, for example, 1 s.
Code 1: monitor progress
Code 2: executing a process
Code 3: integrated auto-load upgrade function
In the technical scheme provided by the embodiment of the invention, the updating state of the file is checked through the execution process, the execution process is restarted by the monitoring process and used for loading the modified upgrading software, and the restarting operation is automatically executed according to the data state of the software, so that the self-loading and updating of the upgrading software are realized, the software upgrading efficiency is improved, the data state in the software service is fully considered, the success rate of software upgrading is favorably improved, and the software version upgrading and patching cost is reduced.
In a specific implementation manner, please refer to fig. 2, based on the above embodiment, the method may further include:
s105: and when detecting that the lock file created by the monitoring process does not exist, operating the execution process to set the state code as a second identification code, and sending the second identification code to the monitoring process to prompt that the lock file does not exist.
When the monitoring process finds that the status code returned by the execution process is the second identification code, the lock file is lost, and the monitoring process creates the lock file, for example, the second identification code may be 2, and when the status code is 2, it indicates that the lock file does not exist.
S106: and judging whether the updating time of the lock file created by the monitoring process is delayed by preset time.
S107: and when the update time of the lock file is delayed by preset time, operating the execution process to set a state code as a third identification code, and sending the third identification code to the monitoring process to prompt that the lock file is not updated.
The preset delay time may be 5s, and of course, other values may be used, which do not affect the implementation of the present application.
When the monitoring process finds that the status code returned by the execution process is the third identification code, the lock file is not updated, and the monitoring process updates the current lock file, for example, the second identification code may be 1, and when the status code is 1, it indicates that the lock file is not updated.
It should be noted that the listening process loops to check that the executing process returns to the status code, i.e., S105-S107 loop to execute until sleeping.
The execution process checks the existence and the updating state of the lock file, feeds back in time, is beneficial to finding as soon as possible, establishing or updating, fully considers the data state in the software service, and is beneficial to improving the success rate of software upgrading.
The embodiment of the invention also provides a corresponding implementation device for the automatic loading method of the upgrade file, so that the method has higher practicability.
