Description

Application program compatible mode operation method and device and computing equipment

Technical Field

The present invention relates to the technical field of compatible operation of applications, and in particular, to an application compatible mode operation method and apparatus, a computing device, and a readable storage medium.

Background

At present, when third-party application software is obtained through an unofficial software package warehouse or the third-party application software is not compiled and finished on a target system and is not subjected to adaptation verification with the target system, the compatible operation problem of the third-party application software can be caused, and the third-party application software is difficult to normally operate with a high probability and is abnormally exited. Reasons for an application exception exit generally include: the application itself has problems with code logic; lack of a corresponding library file or a library file version mismatch, etc. For the missing of library files, a system manufacturer generally provides a software package corresponding to the missing library files; and aiming at the mismatch of the library file versions, the application program manufacturer conducts recompilation adaptation based on the current system.

It can be seen that, in the currently known technology, when the application program and the target system are incompatible, the application program is usually adapted individually for the current system, and the method for adapting is generally based on recompilation and the like of the current system. Doing so increases the maintenance cost of the application. And because the application program directly exits and is not restarted, the exiting is counted as the starting failure, and although recompilation and adaptation can be carried out aiming at the incompatibility problem, the success rate of starting the application program is not increased.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

As described in the background section, when the third-party application software is acquired through the unofficial software package repository, or the third-party application software is not compiled and completed on the target system and is not adapted and verified with the target system, the compatible operation problem of the third-party application software may be caused, and it is difficult to normally operate the third-party application software with a high probability. According to the technical scheme of the invention, the main idea for solving the problem is as follows: and when the application program exits abnormally, matching out a proper library file required by the running of the application program through the symbol detection of the dependent library.

According to an embodiment of the invention, an application compatible mode operation method is provided. Fig. 1 is a schematic diagram showing an overall architecture of an example of the application compatible mode operation method. As shown in fig. 1, in case of a failed start-up of the application, optionally, the monitoring module determines whether the application is running in a compatible mode. Performing a compatible mode determination may avoid subsequent useless lookup operations, however this step is not required. If so, the compatible controller determines whether an abnormal exit is caused by library file or library symbol missing. If yes, searching the library file or the library file corresponding to the missing symbol, and placing the obtained library file into a local directory corresponding to the application program. Alternatively, the local directory may be set as an application library priority path. After loading the downloaded library file from the local directory, the application can again run in compatible mode and start successfully.

Fig. 2 shows a schematic flow diagram of an example of the method. As shown in FIG. 2, the method for application compatible mode operation includes steps 210-240. The steps are described in detail below.

In step 210, in response to an application exception exit, the library file is traced from the application portal by the library file trace command to check if the library file is missing, and the symbols of all library files are traced from the application portal by the symbol trace command to check if the symbols are missing. An application portal refers to the initial interface at which an application begins running. Step 220 is performed to determine if a library file is missing, or if a symbol is missing, or if both a library file and a symbol are missing.

FIG. 3 illustrates one example of a specific work process for determining whether an application exits abnormally. As shown in FIG. 3, after an application program, such as APP1, is started, such as through a start menu, the process number of APP1 is added to the watch list. After the APP1 exits, the monitoring module receives the report that the APP1 exits, and then starts to judge whether the state is an abnormal exit state by monitoring the running condition of the application program. In the example shown in fig. 3, whether the exit is abnormal can be determined according to the return value of APP1, the return value of 0 represents normal exit, and non-0 represents abnormal exit. The application program provides a return value when exiting, and the monitoring module can call the application program and receive the return value when exiting. In addition to or instead of determining whether to exit abnormally by using the return value, whether to exit abnormally may be determined by whether the program running time of APP1 is less than a predetermined time. The preset time is set in advance and can be 20 seconds, 30 seconds or any other time. For example, if the running time is less than 30 seconds, it can be determined that APP1 is not successfully started.

That is, whether the application program exits abnormally may be determined by: the return value when the application exits indicates that the application exits abnormally and/or the application runs for less than a predetermined time.

Fig. 4 shows an example of a specific implementation of step 210. As shown in fig. 4, the compatible controller may invoke the library file tracking command "Idd" and the symbol tracking command "nm" to perform this step. Wherein the command "Idd" is used to print a shared library list on which a program or library file depends, and the command "nm" is used to display a symbol table of a binary object file.

Before the step is executed, the method can further comprise the steps of: it is determined whether the application is operating in a compatible mode as shown in fig. 1 and 4. Wherein compatible mode refers to an application running using library files in a repository (also referred to as a compatible library repository). The significance of performing this step is: and only when the application program fails to start, the reason of the failure is that the corresponding library file or library symbol is lacked, and the lacked library file or library symbol corresponding library file is located in the compatible library warehouse, the subsequent steps of searching the library file and the like are executed.

In step 220, in the case where the missing library file is found through the library file tracking command, the library file is matched in the repository according to the name and version of the found missing library file.

In step 230, in the case where the missing symbol is found through the symbol tracking command, the library file is matched in the repository according to the found missing symbol.

Fig. 5 shows an example of a specific procedure of this step. This step may be performed by the warehouse module, as shown in fig. 5. Specifically, the compatible controller sends the searched name and version of the missing library file and a list (symbol table) formed by the missing symbols to the warehouse module, and the warehouse module matches the library file in the warehouse according to the library name, version and symbols and sends the matched information to the compatible controller. In the event that no matching library file is found in the repository, information about the missing library file is added to the list to be added and maintenance personnel is notified to add the library file.

In step 240, the matched library file is downloaded to the local directory. This step is illustrated in FIG. 4, where the compatibility controller downloads the matched compatible library file to a local directory (which may be referred to as a "local compatible library directory," or a "local shared library directory").

The method can also comprise the step of loading the matched LIBRARY file from the local directory by using a LIBRARY file loading command LD _ LIBRARY _ PATH and restarting the application program.

The local compatible library or shared library is briefly described below. The dynamic link library is a way to realize the concept of sharing a function library, and is a file with an extension of dll in a windows system, and is a file with an extension of so in a linux system. Statically linked libraries are distinguished from dynamically linked libraries, where functions and data are compiled into a binary file and the compiler will recover these functions and data from the static library and combine them with other modules in the application during the linking process to generate an executable file.

There are many factors that may cause the shared library to lose ABI (Application Binary Interface) compatibility, including, for example, different versions of compilers, operating systems and hardware platforms, etc. Thus, the shared library is not typically written in C + + because the C + + standard does not specify standards at the ABI level, resulting in each version of the compiler having its own interpretation.

In addition, in order to solve the difficulty of code management caused by the upgrade change of the shared library, a better solution is version management, for example, naming the shared library as follows: libname.so.x.y.z. Wherein, x is the major version number, which represents the major upgrade of the library, y is the minor version number, which represents the incremental upgrade of the library, i.e. some new interfaces are added, and z is the release version number, which represents some error corrections and performance improvements of the library, and no new interface is added.

According to the embodiment of the invention, the invention further provides an application program compatible mode running device. Fig. 6 shows a schematic block diagram of an example of the application compatible mode operating device 600. As shown in fig. 6, the application compatible mode operating means 600 includes modules 610-620. The modules are described in detail below.

The compatible controller module 610 is configured to: in response to an application exception exit, the library file is tracked from the application entry by a library file tracking command to check if the library file is missing, and the symbols for all library files are tracked from the application entry by a symbol tracking command to check if the symbols are missing. An application portal refers to the initial interface at which an application begins running. The compatibility controller 610 is used to check whether a library file is missing, or a symbol is missing, or both a library file and a symbol are missing.

The warehouse module 620 is configured to: under the condition that the missing library file is found through the library file tracking command, matching the library file in the warehouse according to the name and the version of the found missing library file; and matching the library file in the warehouse according to the searched missing symbol under the condition that the missing symbol is searched through the symbol tracking command. Alternatively, in the event that no matching library file is found in the repository, the repository module 630 adds information about the missing library file to the to-be-added list and notifies maintenance personnel to add the library file.

The compatible controller 620 is also configured to download the matched library file to a local directory (which may be referred to as a "local compatible library directory").

The application compatible mode operating device 600 may further include: and the restarting module is used for loading the matched LIBRARY file from the local directory by using a LIBRARY file loading command LD _ LIBRARY _ PATH and restarting the application program.
