The present embodiment takes the configuration of the file upgrade method of the wearable device in the electronic device as an example.
It should be noted that, the execution subject in the embodiment of the present application may be, for example, a processor of the wearable device in hardware, and may be, for example, an associated background service of the wearable device in software, which is not limited to this.
As shown in fig. 1, the file upgrade method of the wearable device includes:
s101: and obtaining a compressed file from the external equipment, wherein the compressed file is obtained by compressing the file to be upgraded by the external equipment by adopting a compression algorithm.
The external device may be, for example, a server or an external electronic device, and the external device is used to upgrade functions of the wearable device, such as firmware version or UI resource update.
The embodiment of the application obtains the compressed file from the external device, and the compressed file is obtained by compressing the file to be upgraded by the external device through the compression algorithm, so that compared with the prior art that the original file in the wearable device is directly upgraded, the embodiment of the application obtains the compressed file from the external device, such as the compressed file, by compressing the file to be upgraded by the external device through the open-source compression algorithm, so that the compressed file can be upgraded to obtain the target file, and the file in the wearable device can be upgraded quickly.
Optionally, the compression algorithm is any one of: the other compression algorithms may be, but not limited to, a QuickLZ compression algorithm, a FastLZ compression algorithm, an LZF compression algorithm, or a zlib compression algorithm, or may be any other compression algorithms with any open sources.
That is to say, the compressed file is obtained by compressing the file to be upgraded in advance by the external device using any one of the compression algorithms, and when the external device compresses the compressed file, a communication link with the wearable device may be established, so that the compressed file is sent to the wearable device based on the communication link, and thus, the wearable device may obtain the compressed file from the external device.
S102: and upgrading the compressed file to obtain a target file.
The wearable device may directly upgrade the compressed file after acquiring the compressed file from the external device, to obtain the target file, for example, the target file may be obtained by calling a pre-configured script file, and executing the script file to upgrade the compressed file.
In this embodiment, referring to fig. 2, the step of obtaining a target file by encoding a file to be upgraded by an external device using an encoding algorithm, where the compressed file carries a first check code, and the first check code is obtained by upgrading the compressed file, includes:
s201: and upgrading the compressed file to obtain a target compressed file.
The first check code is used for assisting in verifying the legitimacy of the subsequent decompressed file, and therefore the safety and the practicability of upgrading can be effectively guaranteed.
Optionally, the encoding algorithm is a CRC32 algorithm, or may be any other possible encoding algorithm, which is not limited in this respect.
The wearable device can directly upgrade the compressed file after acquiring the compressed file from the external device to obtain a target compressed file, and the file obtained by upgrading the compressed file can be called as the target compressed file.
S202: and decompressing the target compressed file to obtain a decompressed file.
After the update, the target compressed file may be decompressed to obtain a decompressed file, that is, the wearable device may directly update the compressed file to obtain the target compressed file, and then decompress the target compressed file, at this time, the target compressed file may be decompressed by using a decompression algorithm corresponding to the compression algorithm described above to obtain the decompressed file.
After the target compressed file is decompressed to obtain the decompressed file, the file data corresponding to the decompressed file is written into the target address, so that the file data corresponding to the decompressed file is stored in a standardized manner, the sequential reading of the subsequent file data is assisted to generate a corresponding second check code, and the application reliability of the file upgrading method is guaranteed.
S203: and generating a second check code according to the decompressed file.
The file data corresponding to the decompressed file is written into the target address, and the file data can be read from the target address; the file data is encoded according to an encoding algorithm, thereby generating a second parity.
That is, the file data is read from the target address after the target compressed file is decompressed and the decompressed file is obtained; and coding the file data according to a coding algorithm so as to generate a second check code, wherein the second check code is used for matching with the first check code so as to verify the legality of the decompressed file, thereby ensuring the upgrading safety.

S204: and carrying out validity verification on the decompressed file according to the first check code and the second check code.
In some embodiments, the validity verification of the decompressed file is performed according to the combination of the first check code and the second check code, which may be to judge whether the matching state of the first check code and the second check code conforms to a preset matching state; if the verification result accords with the set matching state, the verification of the legality of the decompressed file is determined to be passed, the method is simple and convenient to implement, and excessive computing resources cannot be consumed.
For example, if the matching states of the first check code and the second check code are consistent within the error range, it is determined that the matching states of the first check code and the second check code are in accordance with the set matching state, otherwise, it is determined that the matching states of the first check code and the second check code are not in accordance with the set matching state.
Of course, any other possible manner may be selected to perform validity verification on the decompressed file according to the first check code and the second check code, which is not limited herein.
S205: and if the validity verification is passed, taking the decompressed file as a target file.
The target file is the upgraded file corresponding to the file to be upgraded.
In the embodiment, the compressed file is obtained by obtaining the compressed file from the external equipment, wherein the compressed file is obtained by compressing the file to be upgraded by the external equipment by adopting a compression algorithm; the method has the advantages that the compressed file is upgraded to obtain the target file, and the compressed file to be upgraded is directly upgraded, so that the file upgrading efficiency of the wearable device can be effectively improved, and the practicability and the reliability of file upgrading are effectively guaranteed.
The application further provides an example that the external device compresses the file to be upgraded by using a compression algorithm to obtain a compressed file, and the specific description is as follows:
in some embodiments, the file to be upgraded includes n data segments, and the compressed file includes n compressed data segments, where the data amount of n-1 data segments is equal to the preset value, the data amount of the remaining one data segment is less than or equal to the preset value, and n is a positive integer greater than 1.
The external device compresses a file to be upgraded by using a compression algorithm to obtain a compressed file, which may be obtained by sequentially dividing the file to be upgraded into n data segments, so that each data segment of the file to be upgraded may be compressed by using a segment-by-segment compression method, where the compressed file includes n compressed data segments, the data amount of n-1 data segments is equal to a preset value, the data amount of the remaining one data segment is less than or equal to the preset value, and n is a positive integer greater than 1.
The preset value may be, for example, 4 KB.
It should be noted that the minimum erase unit of the storage NOR/NAND flash memory used by the embedded device is 4KB, so the compressed file is generally much larger than 4KB, otherwise no compression is necessary.
For example, the preset algorithm may be an open source compression and decompression algorithm, and the compression method according to the embodiment of the present application includes:
step S1: it is determined whether the remaining data amount of the current uncompressed file is greater than 4KB, wherein if not less than 4KB, step S2 is performed, otherwise step S4 is performed.
Step S2: the first 4KB data segment of the file is compressed using a compression algorithm (e.g., QuickLZ, FastLZ, LZF, zlib, etc.) and the compressed data is written to the compressed file.
Step S3: the data amount of the current uncompressed file is subtracted by 4KB, and step S1 is re-executed.
Step S4: the remaining less than 4KB of data of the current file is compressed using a compression algorithm and the compressed file is written.
It will be appreciated that the compression is complete and that the compression rates for the different compression algorithms are different (e.g., about QuickLZ 47%, about FastLZ 50%, about LZF 50%, about zlib 37%).
It should be noted that, for the compressed file, an identifier for performing validity verification may be added in the embodiment of the present application, for example, the CRC32 is calculated for the file to be upgraded, and the CRC32 is recorded in the identifier for performing validity verification, so as to generate the first verification code.
In some other embodiments, when the file to be upgraded includes n data segments, and the compressed file includes n compressed data segments, where the data amount of n-1 data segments is equal to the preset value, the data amount of the remaining one data segment is less than or equal to the preset value, and n is a positive integer greater than 1, the step of decompressing the target compressed file to obtain the decompressed file in the embodiment shown in fig. 2 may be further specifically detailed as:
optionally, the target compressed file includes a plurality of compressed data segments, where the compressed data segments correspond to the data segments one to one, and the decompressing the target compressed file to obtain a decompressed file includes: and decompressing each compressed data segment by segment to obtain a decompressed file.
Optionally, the target compressed file includes a plurality of compressed data segments, the compressed data segments correspond to the data segments one to one, the compressed data segments have corresponding sequence numbers, and the target compressed file is decompressed to obtain a decompressed file, including: decompressing the compressed data segment to obtain decompressed data corresponding to the compressed data segment; and combining the plurality of decompressed data according to the sequence number of the compressed data segment to obtain the decompressed file.
Therefore, a flexible decompression method is provided, the applicability of the upgrading method is effectively improved, the upgrading requirements under various different application scenes can be effectively adapted, and the use experience of a user is improved.
The step of decompressing each compressed data segment by segment to obtain a decompressed file may be as follows:
step S1: judging the identification of the file which is not decompressed currently, if the identification fails, executing the step S8, otherwise executing the step S2.
Step S2: and judging whether the data volume of the data header of the file which is not decompressed currently is 4KB or not.
Step S3: and if the decompressed data size is 4KB, decompressing the compressed data segment specified by the current data header by using a decompression algorithm corresponding to the compression algorithm, and then writing the decompressed 4KB data into the target address.
Step S4: if the decompressed data amount is less than 4KB, step S6 is performed, otherwise step S5 is performed.
Step S5: the data amount of the compressed data segment is subtracted from the data amount of the file that is not currently decompressed, and the next header is found, and step S2 is performed.
Step S6: decompressing the residual data volume, and writing the decompressed data into the target address.
Optionally, in an embodiment of the present application, the method of the embodiment of the present application further includes: verifying the legality of the decompressed file according to the combination of the first check code and the second check code; and if the validity verification is passed, taking the decompressed file as a target file.
For example, the CRC32 calculation is performed on the decompressed file of the target address to obtain the second check code, and the second check code is compared with the first check code in the identification mark, if the second check code matches with the first check code, the decompression is considered to be successful, otherwise, the decompression is considered to be failed.
Specifically, since most resource contents have a high repetition rate and a high compression rate on average, the original file size is 234KB, the compressed size is 45KB, and the compression rate is about 20% in the QuickLZ example. On the same MI8SE mobile phone, the downloading time can be increased to 4 seconds from the original 26 seconds, the compression file of 45KB needs 10 seconds to be decompressed into the original file of 234KB, the total time consumption is 14 seconds, and the total time of upgrading is saved by 12 seconds, so that the upgrading efficiency is effectively increased, and the upgrading experience of a user for wearable equipment is improved.
