Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.

First, an application scenario of the present disclosure will be explained. The method can be applied to a terminal with an android operating system, the version information of the currently running system version is obtained in the terminal starting process according to the default processing mode of the android system, whether the currently running system version is updated or not is determined according to the version information, and if the currently running system version is determined to be updated, a fsck (file system check) tool carried by the system is triggered to check the file system of the terminal; and if the currently running system version is determined not to be updated, the fsck tool is not triggered to check the file system of the terminal. However, the system version may not be updated because the source code file of the file system is modified, but may also be updated because other source code files are modified, so that when the source code of the file system is not modified, fsck is still triggered to check the file system, and files contained in the file system are more, and the check of the file system takes about 10 seconds, which results in a long startup time of the terminal, thereby resulting in a poor user experience.

The disclosure provides a terminal starting method, a device, a storage medium and a terminal for overcoming the technical problems in the related art, wherein whether a file system of the terminal is updated or not is determined through a hash value of a current file corresponding to the file system, and fsck is not triggered to check the file system under the condition that the file system is not updated, so that the starting speed of the terminal can be increased, and the user experience is improved.

The present disclosure is described below with reference to specific examples.

Fig. 1 is a flowchart illustrating a terminal booting method according to an exemplary embodiment, and as shown in fig. 1, the method may include:

s101, in the process of starting the terminal, obtaining a current file hash value corresponding to a file system of the terminal.

The file hash value is used for representing the content of a source code file in the file system, and the file hash value corresponding to the file system changes when the content of any source code file in the file system changes. The file hash value may be stored in a preset environment variable, or may be stored in version information of a system version currently running in the terminal.

The file hash value can be obtained in advance through the following modes: in the process of compiling the source code corresponding to the file system of the terminal, calculating a first hash value corresponding to each source code file in the file system through a preset hash algorithm, and then obtaining the file hash value according to a plurality of first hash values. The predetermined hash algorithm may be a hash, or other hash algorithms in the prior art, which is not limited in this disclosure.

For example, in the case that the preset hash algorithm is a sharsum, a command for obtaining a hash value may be added to the mkcomplie _ h file of the source code of the android, and when all the source code files in the source/include/linux/f2fs _ fs.h and the source/fs/f2fs directories are compiled, a first hash value corresponding to each source code file may be calculated through the sharsum algorithm. Then, a new hash value file is generated by the plurality of first hash values, for example, the plurality of first hash values may be sequentially spliced to obtain the hash value file, and finally, the hash value corresponding to the hash value file is calculated by the sharsum algorithm, and the hash value corresponding to the hash value file is used as the file hash value.

It should be noted that the hash value corresponding to the hash value file may also be calculated by other hash value algorithms, which is not limited in this disclosure.

The first hash value may include a plurality of bytes, and a byte number corresponding to the first hash value may be determined according to the preset hash algorithm, for example, the first hash value calculated by the sharsum algorithm may include 160 bytes. Under the condition that the number of bytes corresponding to the first hash value is large, the hash value file generated according to the plurality of first hash values is also long, so that the efficiency of calculating the hash value corresponding to the hash value file is low.

In a possible implementation manner, a second hash value corresponding to the designated byte of each first hash value may be obtained, and the hash value of the file is calculated by the preset hash algorithm according to a plurality of second hash values. Illustratively, the specified byte may be the first byte of the first hash value. After the second hash value corresponding to the designated byte of each first hash value is obtained, a hash value file may be generated according to the plurality of second hash values, and then the hash value corresponding to the hash value file is obtained through the preset hash algorithm, and the hash value corresponding to the hash value file is used as the file hash value.

Further, after the file hash value is obtained through calculation, the file hash value can be stored in a preset environment variable, so that the terminal can obtain the current file hash value by reading the value of the preset environment variable in the starting process; after the compilation is completed, the file hash value may be added to the version information of the system version generated by the compilation, for example, the file hash value may be added to the last of the version information, for example, if the file hash value is "8e3c99a365cc2c2274d76c8d4a4441e750a6eab6", the version information to which the file hash value is added may be "#1SMP PREEMPT wen 2.

It should be noted that the length of the string corresponding to the version information defined in the source code may be limited, for example, the length of the string corresponding to the version information may be limited to 64 bytes, in this case, the target file hash value may be determined according to the length of the string that may be added to the version information, and the target file hash value may be added to the version information. For example, if the length of the character string that can be added to the version information is 11 bytes, the first 11 bytes in the file hash value can be used as the target file hash value. For example, the hash value of the target file is "8e3c99a365c", and the version information to which the hash value of the file is added may be "#1SMP PREEMPT Wed Jun 2 17. Therefore, the file hash value is stored without adding an environment variable and under the condition that the source code is slightly modified.

In this step, in the terminal starting process, if the current file hash value is stored in the version information, the version information of the system version currently running by the terminal may be obtained, and the version information is analyzed to obtain the current file hash value in the version information. For example, the version information may be parsed to obtain a preset character string "fsfs-hash" in the version information: ", the character string following the preset character string is taken as the hash value of the current file.

And S102, determining whether the file system of the terminal is updated or not according to the hash value of the current file.

In this step, after obtaining the current file hash value corresponding to the file system of the terminal, the historical file hash value corresponding to the file system of the terminal may be obtained from the data partition of the terminal, and when the current file hash value is the same as the historical file hash value, it is determined that the file system of the terminal is not updated, and when the current file hash value is different from the historical file hash value, it is determined that the file system of the terminal is updated.

For example, after the current file hash value and the historical file hash value are obtained, each byte in the current file hash value and each byte in the historical file hash value may be sequentially compared, and if the hash values of the current file hash value and each byte in the historical file hash value are the same, it indicates that the system file of the current running system version of the terminal is the same as the system file of the historical system version, and it is determined that the file system of the terminal is not updated; if the hash value of any byte of the hash value of the current file is different from that of any byte of the hash value of the historical file, the hash value of the current file indicates that the system version currently operated by the terminal is different from the system file of the historical system version, and the file system update of the terminal is determined.

S103, skipping the file system check of the file system when the file system is determined not to be updated.

In this step, in the case that it is determined that the file system is not updated, fsck may not be triggered any more, and the file system check for the file system may be skipped.

It should be noted that the processing flow related to fsck is skipped when checking the file system of the file system indicates that fsck is not executed any more, and the processing flow after fsck is executed as it is.

In the case that the file system update is determined, the historical file hash value in the data partition of the terminal may be updated to the current file hash value, and fsck is triggered to check the file system.

By adopting the method, whether the file system is updated or not is determined through the hash value of the current file corresponding to the file system of the terminal, and fsck is not triggered to check the file system under the condition that the file system is not updated, so that the starting speed of the terminal can be increased, and the user experience is improved.
