In practical use, when a processor executes an application program, information of the application program needs to be read from a disk into a memory, and the processor accesses the information of the application program from the memory. However, when the processor accesses exception data for the application, such as an exception code section, the application may exit abnormally. In some cases, the reason why the information of the application program is abnormal may be that after the information is loaded from the disk to the memory, the information loaded into the memory is abnormal due to a hardware problem of the memory, or the information in the memory is maliciously tampered.

The currently adopted repair method is that when detecting that an application program exits abnormally for multiple times within a certain time, a prompt box pops up to prompt a user that the application program is abnormal. And the user manually restores the application program by restarting the device and the like. However, the repair method requires user participation and equipment restart to reload all data of the application program into the memory, and has low repair efficiency and poor user experience.

In order to solve the foregoing technical problem, an embodiment of the present application provides a method for repairing an abnormal exit of an application program, where when the abnormal exit of a target application program is detected, location information of first data related to the abnormal exit of the target application program in a memory is obtained, the first data is cleared from the memory according to the location information of the first data in the memory, and original data of the first data is read from a disk into the memory, so that a processor can normally run the target application program according to the original data of the first data, thereby implementing repair of the target application program. According to the restoration method, users do not need to participate, equipment does not need to be restarted, only the data with errors need to be restored, the whole data of the target application program does not need to be loaded into the memory, the restoration efficiency is high, the target application program can be automatically restored under the condition that the users and the target application program are not aware (namely the users are not interfered, and the target application program is not suspended), and user experience is good.

The following describes, by way of specific examples, a repair procedure for application exception exit according to an embodiment of the present application.

Fig. 3 is a schematic flowchart of a method for repairing an application exception exit according to an embodiment of the present application, and fig. 4 is a schematic diagram of a repairing process according to an embodiment of the present application. As shown in fig. 3 and 4, the method of the embodiment of the present application includes:

s101, when abnormal exit of the target application program is detected, first position information of first data in a memory is obtained.

The method for repairing application exception quit provided by the embodiment of the application can be applied to the electronic device shown in fig. 1 or the computing device shown in fig. 2.

The execution subject of the embodiment of the present application may be the processor in fig. 1 or fig. 2 described above.

Specifically, when detecting that the target application program exits abnormally (crash), the processor obtains first location information of the first data in the memory, where the first location information may be understood as storage location information, or a storage address, of the first data in the memory.

The first data is data related to abnormal exit of the target application, and is, for example, data such as parameters and program instructions related to the target application. That is to say, due to some reasons, for example, a hardware problem of the memory, or information in the memory is maliciously tampered, the first data stored in the memory is abnormal, and when the processor reads the abnormal first data, the target application program is abnormally exited. Optionally, the first data is read-only data.

S102, clearing the first data from the memory according to the first position information of the first data in the memory.

Specifically, after the processor obtains first location information of first data in the memory, which causes the target application program to exit abnormally, the processor clears the first data from the memory according to the first location information, so that the processor reads correct information.

In some embodiments, the clearing the first data from the memory according to the first location information of the first data in the memory in S102 may include step B:

and B, clearing the first data from the memory according to the first position information of the first data in the memory and the preset length of the first data.

Specifically, as shown in fig. 5, the first location information may be understood as a starting location a1 of a storage location of the first data in the memory, and the preset length of the first data is b. In this way, the processor may query the starting storage location a1 of the first data in the memory according to the first location information of the first data in the memory, shift the length b from the location a1, obtain the ending storage location a2 of the first data in the memory, and delete the first data from the location a1 to the location a2 in the memory.

It should be noted that the preset length of the first data is set according to an actual situation, and the embodiment of the present application does not limit this.

In some examples, the preset length of the first data is 8 bytes, that is, 64 bits.

S103, reading the original data of the first data from the disk to a memory.

The original data of the first data is data which is not tampered and can be used for normal operation of the target application program.

Specifically, according to the step S102, after the processor clears the first data from the memory, the processor reads the original data of the first data from the second device, and stores the read original data of the first data in the memory. In this way, the processor can read the original data of the first data which is not tampered from the memory, and normal operation of the target application program is achieved.

In this embodiment of the application, the processor reads the original data of the first data from the disk into the memory under the following several conditions.

In case 1, after the processor clears the first data from the memory, the processor immediately reads the original data of the first data from the disk into the memory. That is, the trigger condition for the processor to read the original data of the first data from the disk into the memory is that the first data in the memory is detected to be cleared.

In case 2, when detecting that the target application program is restarted, reading original data of the first data from the disk into the memory. That is, after the processor clears the first data from the memory, the original data of the first data is not immediately read from the disk to the memory, but when it is detected that the target application program is restarted and the first data cannot be read from the memory, the original data of the first data is read from the disk to the memory.

From the above, the embodiments of the present application

According to the method for repairing the abnormal exit of the application, when the abnormal exit of the target application is detected, the first position information of the first data related to the abnormal exit of the target application in the memory is obtained, the first data is cleared from the memory according to the first position information of the first data in the memory, and the original data of the first data is read from the disk to the memory, so that the processor can normally run the target application according to the original data of the first data, and the quick repair of the target application is realized. According to the restoration method, users do not need to participate, equipment does not need to be restarted, when the target application program is abnormal, only wrong data, namely first data, is restored, and all data of the target application program do not need to be reloaded into the memory.

On the basis of the foregoing embodiment, the present application describes in detail a specific process of acquiring the first location information of the first data in the memory in S101.

Fig. 6 is another schematic flow chart of the method for repairing an application exception exit provided in the embodiment of the present application, and as shown in fig. 6, the method in the embodiment of the present application includes:

s201, when abnormal exit of the target application program is detected, second position information of the original data of the first data in the disk is obtained.

Since the first data in the memory is a mirror image of the original data of the first data in the disk, the storage location of the first data in the memory can be obtained by obtaining the storage location of the original data of the first data in the disk.

Specifically, when the processor detects that the target application program exits abnormally, the processor obtains second position information of the original data of the first data in the disk. And then, obtaining first position information of the first data in the memory according to second position information of the original data of the first data in the disk.

In some examples, the original data of the first data is stored in a first file in the disk, and at this time, the second location information of the original data of the first data in the disk may include: the information of the first file in the disk, and the address offset of the original data of the first data in the first file.

Optionally, the information of the first file may be identification information of the first file, and the identification information of the first file may include a file name of the first file.

Optionally, the information of the first file may be a storage path of the first file in the disk, for example, the storage path of the first file in the disk is:

/data/dalvik-cache/arm64/system@app@iConnect@iConnect.apk@classes.dex。

in some embodiments, when the first data is an instruction related to abnormal exit of the target application, the acquiring, in S201, second location information of the original data of the first data in the disk includes step S2011:

step S2011, second position information of the original data of the first data in the disk is obtained from the preset file.

The preset file may be a preset file for storing second location information of the original data of the first data in the disk.

In some examples, the preset file may be a tombstone (tombstone) which records location information of original data of the first data in the disk.

In some examples, when the embodiment of the present application is applied to an Android operating system (Android), the preset file may be: android native dimension log, which may record some information when an exception (crash) occurs to an application, for example, including: information of the first file, an address offset of original data of the first data in the first file.

Optionally, the preset file may be generated when the processor reads the original data of the first data from the disk to the memory for the first time.

Optionally, the preset file is generated when the target application program exits abnormally. When the processor accesses the first data, the target application program exits abnormally, at this time, a preset file is generated, and second position information of the original data of the first data in the disk is stored in the preset file.

In some embodiments, as shown in fig. 7, the step S2011 of obtaining, from the preset file, second location information of the original data of the first data in the disk may include steps S2011a to S2011 b:

and S2011a, obtaining the type of the abnormal exit of the target application program from the preset file.

S2011b, when the type of the abnormal exit of the target application is to execute the first data, obtaining, from the preset file, second location information of the original data of the first data in the disk.

The preset file of the embodiment of the application comprises: and the type of the abnormal exit of the target application program and second position information of the original data of the first data in the disk.

The type of the target application program abnormal exit can integrally comprise two types, wherein the first type is as follows: the second class is due to exceptions caused by the execution of the first data: not an exception due to execution of the first data.

Based on this, when the processor detects that the target application program abnormally exits, the processor obtains the type of the abnormal exit of the target application program from the preset file, and judges whether the type of the abnormal exit of the target application program is the abnormal exit caused by executing the first data, if so, the first data in the memory is falsified. At this time, the processor obtains second position information of the original data of the first data in the disk from the preset file, and obtains first position information of the first data in the memory according to the second position information. Then, the processor may clear the first data from the memory according to first location information of the first data in the memory, and read the original data of the first data from the disk to the memory according to second location information of the original data of the first data in the disk, so as to ensure that the original data of the first data stored in the memory is normal data without tampering.

For example, taking the Android system as an example, when the processor detects that the target application program sends an abnormal exit (crash), the Android system generates a corresponding preset file (for example, a tombstone file) in a specific directory as shown below.

The tombstone file contains: the type of the target application abnormal exit at this time (i.e. code1(ILL _ ILLOPC)), and information such as the second location information of the original data of the first data in the disk (i.e. 00pc00000000007858e0/data/dalvik-cache/arm64/system @ app @ iConnect. apk @ classes. dex). The processor monitors generation of the tombstone file and analyzes content of the tombstone file, so that the type of crash generated by the target application program is ILL _ ILLOPC, and second position information of original data of the first data in the disk can be acquired.

The ILL _ ILLOPC indicates that the type of exception occurring in the target application is an exception caused by executing the first data.

Optionally, the first data is a PC instruction.

S202, obtaining first position information of the first data in the memory according to second position information of the original data of the first data in the magnetic disk.

Continuing with the above example, assume that the second location information of the original data of the first data in the disk is: 00pc00000000007858e 0/dara/dalvik-cache/arm64/system @ app @ iConnect @ iConnect.apk @ classes.de x. Wherein,/data/dalvik-cache/arm 64/system @ app @ iConnect @ iconnect.apk @ classes.dex is the storage path of the first file in the disk. 0x7858e0 denotes an offset of original data of the first data in the first file.

In this way, the processor may obtain the first location information of the first data in the memory according to the second location information of the original data of the first data in the disk.

In some embodiments, as shown in fig. 8, in the above S202, the processor obtains the first location information of the first data in the memory according to the second location information of the original data of the first data in the magnetic disk, which may include S2021 to S2023.

S2021, accessing the first file in the magnetic disk according to the information of the first file.

Continuing with the above example, assume that the second location information of the original data of the first data in the disk is: 00pc00000000007858e0/data/dalvik-cache/arm64/system @ app @ iConnect @ iConnect.apk @ classes.de x.

The information of the first file may be a storage path of the first file in the disk, that is:

/data/dalvik-cache/arm64/system@app@iConnect@iConnect.apk@classes.dex。

the processor accesses the first file in the disk according to the information of the first file.

In one example, the processor may access the first file in the disk according to the information of the first file by: opening a first file storing original data of the first data in the disk through an open function, and acquiring a file handle fd:

int fd＝open(/data/dalvik-cache/arm64/system@app@iConnect@iConnect.apk@classes.dex，O_RDONLY)。

s2022, obtaining third location information of the original data of the first data in the first file according to the address offset of the original data of the first data in the first file.

Continuing with the example above, the address offset of the original data of the first data in the first file may be 0x7858e0 as described above.

In this way, after the processor opens the first file in the disk by the open function according to the information of the first file, the processor obtains the position information of the original data of the first data in the first file according to the address offset (for example: 0x7858e0) of the original data of the first data in the first file, and records the position information as the third position information. Specifically, the storage location of the original data of the first data in the first file is obtained by an offset of 0x7858e0 from the initial address of the first file, and the storage location is recorded as third location information of the original data of the first data in the first file.

S2023, obtaining the first location information of the first data in the memory according to the mirror image of the third location information in the memory.

Specifically, the processor obtains first location information of the first data in the memory according to a mirror image of third location information of the original data of the first data in the first file in the memory.

In this way, the processor may clear the first data from the memory according to the first location information of the first data in the memory and the preset length of the first data.

In one possible implementation, the processor may clear the first data in the memory by a posix _ fadvise function.

posix_fadvise(fd，0x7858e0，8，POSIX_FADV_DONTNEED)

Wherein fd denotes a storage path of the first file in the disk, 0x7858e0 denotes an address offset of original data of the first data in the first file, 8 is a length of the first data, and POSIX _ FADV _ dotted means that the first data is cleared from the memory.

According to the method for repairing the abnormal exit of the application, when the abnormal exit of the target application program is detected, second position information of original data of the first data in the disk is obtained, first position information of the first data in the memory is accurately obtained according to the second position information of the original data of the first data in the disk, the first data is cleared from the memory according to the accurately obtained first position information of the first data in the memory, and accurate clearing of error-reported first data is achieved.
