[0047] The program file compression method provided by the present invention dynamically determines the compression method corresponding to the data of the instruction nodes according to the data length of the instruction nodes of the function in the target program file, and writes the data of the instruction nodes into the corresponding compressed program file of the target program file by using the data length indicated by the compression method, so as to compress the data of the instruction nodes, thereby saving the storage space of the data.

[0050] Step 220, determine the compression method corresponding to the data of the instruction node according to the target compression relationship and the data length of the instruction node; wherein, the target compression relationship is used to represent the corresponding relationship between the numerical range and the compression method.

[0051] Optionally, according to the numerical range corresponding to the data length of the instruction node, determine the compression method corresponding to this numerical range in the target compression relationship.

[0052] Optionally, the data of the instruction node is a single number or an array; among them, the data of the return instruction node and the indirect jump node is a single number, such as

[128] , while the data of the address pair node is an array, such as [[1001, 10], [1002, 10]]; where 1001 represents the starting address of the address pair node, 1002 represents the target address of the address pair node, and 10 represents the number of the target program file.

[0056] The program file compression method provided by the present invention dynamically determines the compression method corresponding to the data of the instruction node according to the compression target relationship and the data length of the instruction node of the function in the target program file, and writes the data of the instruction node into the compressed program file corresponding to the target program file by using the data length indicated by the compression method, so as to compress the data of the instruction node, thereby saving the storage space of the data.

[0058] It should be noted that the first two digits of the compression method represent indication information, which is used to indicate the corresponding compression method with different identifiers. For example, when the indication information of the compression method is 00, this indication information means that the compression method corresponds to storing 1 byte of data, and the data storage range of the compression method storing 1 byte is 0 to 64; when the indication information of the compression method is 01, this indication information means that the compression method corresponds to storing 2 bytes of data, and the data storage range of the compression method storing 2 bytes is 0 to 16384; when the indication information of the compression method is 10, this indication information means that the compression method corresponds to storing 4 bytes of data, and the data storage range of the compression method storing 4 bytes is 0 to 1073741824; when the indication information of the compression method is 11, this indication information means that the compression method corresponds to storing 8 bytes of data, and the data storage range of the compression method storing 8 bytes is 0 to 4.6116860184274e+18.

[0059] Figure 3 Schematic diagram for determining the compression method of instruction nodes provided by the present invention, as Figure 3 shown, 1 byte is 8 bit, and the data storage range is 0 to 64; among them, the first two digits 00 represent the indication information of this compression method, and this indication information is used to indicate that the compression method of 1 byte stores data, and the data starts to be stored from the 3rd bit. 2 bytes are 16 bit, and the data storage range is 0 to 16384; among them, the first two digits 01 represent the indication information of this compression method, and this indication information is used to indicate that the compression method of 2 bytes stores data, and the data starts to be stored from the 3rd bit. 4 bytes are 32 bit, and the data storage range is 0 to 1073741824; among them, the first two digits 10 represent the indication information of this compression method, and this indication information is used to indicate that the compression method of 4 bytes stores data, and the data starts to be stored from the 3rd bit. 8 bytes are 64 bit, and the data storage range is 0 to 4.6116860184274e+18; among them, the first two digits 11 represent the indication information of this compression method, and this indication information is used to indicate that the compression method of 8 bytes stores data, and the data starts to be stored from the 3rd bit.

[0060] Figure 4 Schematic diagram III of the program file compression method provided by the present invention, as Figure 4 shown, this method includes:

[0061] Step 410, obtaining at least one function in the target program file.

[0062] Step 420, determining the compression method corresponding to the data of the instruction node according to the data length of the instruction node of the function; the compression method is used to represent the data length adopted when compressing the data of the instruction node.

[0063] Step 430: Write the header information and data content of the instruction node into the compressed program file in sequence based on the data length indicated by the compression method.

[0064] Optionally, write the header information of the instruction node and the data content of the instruction node into the corresponding compressed program file of the target program file in a determined compression method according to the data length indicated by the indication information of the compression method.

[0065] It should be noted that during the actual storage process, the header information of the target program file is stored first, then the header information of at least one function corresponding to the target program file is stored, and then the header information, indication information, and data content of the instruction nodes of at least one function are stored.

[0066] Specifically, taking the instruction node as an indirect jump node as an example, the data content of this indirect jump node is 58, and its corresponding storage range is 0 - 64. According to the target compression relationship, it is determined that the data of this indirect jump node corresponds to a compression method of storing 1 byte, and the indication information of this compression method is 00. The data 58 is stored starting from the 3rd bit.

[0067] In practice, if the next instruction node of this indirect jump node is an address pair node, the data content of this address pair node is [[1001, 10], [1002, 10]]; where the storage ranges corresponding to 1001 and 1002 are 0 - 16384. According to the target compression relationship, it is determined that 1001 and 1002 respectively correspond to a compression method of storing 2 bytes, and the indication information of this compression method is 01; the storage range corresponding to 10 is 0 - 64. According to the target compression relationship, it is determined that the compression method of storing 1 byte is used, and the indication information of this compression method is 00. Therefore, then store the header information of this address pair node, the indication information 01 of data 1001 and data 1001, then store the indication information 00 of the first data 10 of this address pair node and data 10; then, store the indication information 01 of data 1002 and data 1002; finally, store the indication information 00 of the second data 10 of this address pair node and data 10. And so on, store the header information, indication information, and data content of the next instruction node in sequence until the data of the instruction nodes of at least one function are written into the corresponding compressed program file of the target program file in sequence.

[0068] The program file compression method provided by the present invention dynamically determines the compression method corresponding to the data of the instruction nodes in the target program file according to the data length of the instruction nodes of the functions in the target program file, and uses the data length indicated by the compression method to write the header information and data content of the instruction nodes into the corresponding compressed program file of the target program file in the determined compression method in sequence, so as to compress the data of the instruction nodes, thereby saving the storage space of the data.

[0069] Optionally, after writing the data of the instruction nodes of the function into the corresponding compressed program file of the target program file, it is also necessary to determine whether there is still data of other instruction nodes to be compressed in the target program file; if there is data of other instruction nodes to be compressed, then according to the compression method determined previously, write the data of other instruction nodes to be compressed into the compressed program file in sequence until all the data of the instruction nodes in the target program file are processed.

[0070] Figure 5 It is a schematic diagram of the data in the compressed program file provided by the present invention, as Figure 5 shown, a target program file includes a target program file header and multiple functions, each function corresponds to a function header and multiple instruction nodes, and the multiple instruction nodes include at least one of an address pair node, a return instruction node, an indirect jump node, and a sub-function call jump node; wherein, an address pair node contains multiple address pairs, and the multiple address pairs include address pair 1 to address pair n, and the data of address pair 1 to address pair n are all represented in the form of a dynamic array; the data of the return instruction node, the indirect jump node, and the sub-function call node are also represented in the form of a dynamic array. The data of the instruction node includes the header information of the instruction node and the instruction data content, and the instruction data content is stored in the form of a dynamic array.

[0071] Optionally, the present invention also provides a program file decompression method, which can be applied to database decompression scenarios in operating systems such as the linux operating system.

[0072] Specifically, when decompressing the compressed program file, at least one function is obtained according to the compressed program file, and each function corresponds to a function attribute; wherein, the function attribute can be represented by numbers 1 to n. Therefore, according to the function attribute, the node type and header information of the instruction nodes of the function can be determined, and then according to the header information of the instruction nodes, the dynamic compression array of the instruction nodes of at least one function in the compressed program file can be obtained. Then, according to the indication information of the dynamic compression array, the compression method and the data storage range corresponding to the dynamic compression array are obtained, and then the dynamic compression array is parsed according to the compression method to obtain the data of the instruction nodes.
