[0002] Currently, for resource-constrained devices, installing applications typically involves converting binary intermediate files.

[0003] The current conversion method can only convert one binary intermediate file at a time, and the converted file still requires a lot of secondary linking during installation to ensure that the installed application can run normally. This results in a long conversion process and a slow installation speed. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] Example 1

[0027] Figure 1 This is a flowchart illustrating a method for converting and generating binary loadable files according to Embodiment 1 of the present invention. This embodiment is applicable to the conversion and generation of binary loadable files. The method can be executed by a binary loadable file conversion and generation device, which can be implemented in hardware and / or software and can be configured in a resource-constrained device. Figure 1 As shown, the method includes:

[0028] Step 101: When converting any binary intermediate file to be converted, obtain the conversion auxiliary file based on the segment data of the binary intermediate file to be converted.

[0029] In this step, the binary intermediate file is generated by the WebAssembly compiler compiling the application source code. The application source code is a combination of multiple applications implemented in a high-level language. One application combination can use system-provided API functions, or it can use API functions from other application combinations.

[0030] In this embodiment, a conversion auxiliary file can be obtained based on the segment data in the binary intermediate file to be converted. It should be noted that this step can obtain multiple binary intermediate files to be converted and perform parallel conversion. In addition, the segment data in the binary intermediate files to be converted mainly includes import segments, export segments, and function segments. In this embodiment, the conversion is mainly performed on the import segments and export segments.

[0031] In this step, the conversion auxiliary file is mainly obtained by relying on the import segment of the binary intermediate file to be converted. Specifically, the required binary intermediate file identifier can be obtained from the import segment of the binary intermediate file to be converted; then the conversion auxiliary file is obtained based on the binary intermediate file identifier.

[0032] The import section stores several pieces of import function information. Each piece of import information records the name of the binary intermediate file of the imported function, the function name, and the function signature information index. Therefore, the name of the binary intermediate file involved in this import section can be determined as the required binary intermediate file identifier.

[0033] Then, query the link status of the target binary intermediate file corresponding to the binary intermediate file identifier, and obtain the conversion configuration information corresponding to the binary intermediate file identifier.

[0034] It should be noted that the link status is used to identify whether the target binary intermediate file has been converted. Different status values ​​can usually be set to identify different link statuses. For example, a status value of "1" indicates that the corresponding target binary intermediate file is in a linked state, that is, it has been converted; a status value of "0" indicates that the corresponding target binary intermediate file is in an unlinked state, that is, it has not been converted.

[0035] If the link status indicates that the target binary intermediate file is linked, obtain the corresponding target binary link file and identify the target binary link file as the conversion auxiliary file.

[0036] If the link status indicates that the target binary intermediate file is not linked, the target binary intermediate file and the conversion configuration information are identified as conversion auxiliary files.

[0037] Therefore, the content contained in the conversion auxiliary file will be different depending on the link status.

[0038] Additionally, it should be noted that the conversion configuration information includes the configuration information required to convert the binary intermediate file to be converted into a binary loadable file; wherein, the configuration information includes: the identifier of the binary intermediate file to be converted, the module information and exported function information for converting into a binary loadable file, the module information includes: module version, module AID length and module AID, and the exported function information includes: the name of the exported function of the binary intermediate file to be converted.

[0039] Step 102: Convert the intermediate binary file to be converted based on the conversion auxiliary file to obtain the import segment information and export segment information in the converted loadable binary file, as well as the binary link file corresponding to the loadable binary file.

[0040] This step mainly involves converting the import segment in the binary intermediate file, and the converted import segment information is the import segment information in the binary loadable file; the export segment in the binary intermediate file is also converted, and the converted export segment information is the export segment information in the binary loadable file.

[0041] The generated binary link file corresponds to the binary loadable file and the binary intermediate file to be converted. The binary link file specifies the functions in the binary loadable file that can be called by other binary intermediate files.

[0042] In this embodiment, when converting any binary intermediate file to be converted, a conversion auxiliary file is obtained based on the segment data of the binary intermediate file to be converted; the binary intermediate file to be converted is converted according to the conversion auxiliary file to obtain the import segment information and export segment information of the converted binary loadable file, as well as the corresponding binary link file. Using the conversion auxiliary file, the conversion of the binary intermediate file is realized, and the import segment information and export segment information of the binary loadable file, as well as the corresponding binary link file, are obtained. For multiple binary intermediate files, the solution of the present invention can still be implemented simultaneously, which improves the conversion efficiency. The modification of the import segment of the binary intermediate file completes the linking between multiple binary intermediate files, reduces the secondary linking process required during subsequent installation, and improves the installation speed.

[0043] Example 2

[0044] Figure 2 This is a flowchart of a method for converting and generating a binary loadable file according to Embodiment 2 of the present invention. This embodiment describes the conversion and generation process when the target binary intermediate file is already linked. Figure 2 As shown, the method includes:

[0045] Step 201: Obtain the target binary link file corresponding to the target binary intermediate file, and identify the target binary link file as the conversion auxiliary file.

[0046] Based on the determination of the linking status of the target binary intermediate file in the aforementioned embodiments, this embodiment shows that it is already linked. Therefore, the target binary linking file corresponding to the target binary intermediate file can be obtained, and the target binary linking file can be identified as the conversion auxiliary file.

[0047] In other words, in this embodiment, the file used for subsequent conversion is the target binary link file corresponding to the target binary intermediate file.

[0048] It should be noted that in this step, after obtaining the target binary link file corresponding to the target binary intermediate file, the target binary link file can also be verified.

[0049] Specifically, a hash check can be used to compare and verify each target segment in the target binary link file to obtain the first verification result; the magic number and version in the target binary link file can be checked to obtain the check result; the name of the target binary link file and the name of the internally stored binary intermediate file can be compared for consistency to obtain the comparison result; the length and format of the AID and the information of each function in the target binary link file can be verified to obtain the second verification result; if the first verification result, check result, comparison result and second verification result are all passed, the target binary link file is determined to have passed the verification.

[0050] Each target segment may include, but is not limited to, the following fields: magic, version, module_name_size, module_name, module_aid_size, module_aid, export_function_count, and functions, and these fields will be used as the binary linker template file.

[0051] Step 202: Generate a binary link file export function information table based on the target binary link file in the conversion auxiliary file.

[0052] In this step, the target binary link file contains multiple exported functions and related information. Therefore, the exported functions and their related information can be extracted to generate an exported function information table for the binary link file.

[0053] The binary linker export function information table can contain multiple binary linker export function information entries. Each binary linker export function information entry includes the following items:

[0054] The binary intermediate file identifier corresponds to the name of the target binary intermediate file, the version of the target binary intermediate file, the AID of the target binary intermediate file, and the exported function names, indices, number of input parameters, and number of return values ​​contained in the exported segment of the binary link file.

[0055] It should be noted that AID stands for Application Identifier. For the specific definition of the above entries, please refer to relevant technologies, which will not be elaborated here.

[0056] Step 203: Generate an import function information table for the binary intermediate file to be converted based on the import segment of the binary intermediate file to be converted.

[0057] As can be seen from the foregoing embodiments, the import segment of the binary intermediate file to be converted stores several import function information entries. Each import information entry records the name of the binary intermediate file to be converted, the function name, and the function signature information index. This step can generate an import function information table for the binary intermediate file to be converted based on the information in the import segment.

[0058] The table containing the import function information for the binary intermediate file to be converted includes multiple entries for import functions of the binary intermediate file to be converted. Each entry includes the following items:

[0059] The name of the binary intermediate file to which the imported function belongs in the import segment of the binary intermediate file to be converted, the name of the imported function in the import segment of the binary intermediate file to be converted, the number of input parameters of the imported function in the type segment of the binary intermediate file to be converted, and the number of return values ​​of the imported function in the type segment of the binary intermediate file to be converted.

[0060] Step 204: Generate the export function information table of the binary intermediate file to be converted based on the export segment of the binary intermediate file to be converted.

[0061] In this step, the exported segment of the intermediate binary file to be converted contains the function name and function index of the exported function. Based on this index, the signature information and bytecode of the exported function can be found.

[0062] Based on the information from this exported segment, an export function information table for the binary intermediate file to be converted can be generated. This export function information table includes multiple export function information entries for the binary intermediate file to be converted, and each export function information entry includes the following table entries:

[0063] The names of the exported functions in the exported segment of the binary intermediate file to be converted, and the indexes of the exported functions in the binary intermediate file to be converted.

[0064] Step 205: Based on the exported function information table of the binary link file and the imported function information table of the binary intermediate file to be converted, convert the imported segment of the binary intermediate file to be converted to obtain the imported segment information of the converted binary loadable file.

[0065] In this step, when converting the imported segment, the main basis is the export function information table of the binary link file and the import function information table of the binary intermediate file to be converted.

[0066] Since the binary intermediate file import function information table contains multiple binary intermediate file import function entries, this step can iterate through the binary intermediate file import function information entries one by one based on the order in the table. When any binary intermediate file import function entry is encountered, the following processing is performed on that binary intermediate file import function entry:

[0067] For any binary intermediate file import function information in the binary intermediate file import function information table to be converted, traverse all the binary link file export function information tables obtained; for each binary link file export function information in the binary link file export function information table, determine whether the name of the target binary intermediate file in the binary link file export function information is the same as the name of the binary intermediate file in the binary intermediate file import function information.

[0068] If they are different, iterate through the next binary linker's exported function information; if they are the same, end the iteration and replace the AID of the target binary intermediate file corresponding to the binary intermediate file identifier in the binary linker's exported function information with the import module information corresponding to the import section in the binary intermediate file to be converted.

[0069] It should be noted that when traversing the exported function information table of all the obtained binary link files, the traversal of the exported function information table of the binary link files can be ended as soon as the name of the target binary intermediate file that is the same as the name of the imported function information of the binary intermediate file is found.

[0070] Then, the names of the binary link files that have the same target binary intermediate file are used as the data basis for conversion, and the import function information of this binary intermediate file is converted.

[0071] The specific conversion involves replacing the AID of the target binary intermediate file corresponding to the binary intermediate file's identifier in the exported function information of the binary linker with the import module information corresponding to the import section in the binary intermediate file to be converted. This ensures that the import module information only stores the aforementioned AID.

[0072] After the replacement is complete, proceed with the processing of the next binary intermediate file import function information.

[0073] After traversing through all the binary intermediate file import function information in the import function information table of the binary intermediate file to be converted, the duplicates of each import information in the converted import segment are removed to obtain the import segment information of the converted binary loadable file.

[0074] It should be noted that after the conversion is complete, there may be duplicate AIDs in the imported information. In this case, deduplication should be performed to keep only one of the duplicate AIDs.

[0075] Step 206: Convert the export segment of the binary intermediate file according to the export function information table of the binary intermediate file to be converted and the export function information in the conversion configuration information corresponding to the binary intermediate file to be converted, and obtain the export segment information of the converted binary loadable file.

[0076] The conversion of the exported segment is mainly based on the exported function information table of the binary intermediate file to be converted and the exported function information in the corresponding conversion configuration information of the binary intermediate file to be converted.

[0077] Specifically, the binary intermediate file export function information in the binary intermediate file export function information table to be converted is traversed one by one. For each binary intermediate file export function information encountered, the following processing is performed:

[0078] For any binary intermediate file export function information in the binary intermediate file export function information table to be converted, the export function information in the conversion configuration information corresponding to the binary intermediate file to be converted is traversed; for each binary intermediate file to be converted, the function name in the conversion configuration information corresponding to the binary intermediate file to be converted is compared with the function name in the binary intermediate file export function information.

[0079] If the same function is found during iteration, delete the function name from the exported information in the exported segment of the binary intermediate file; if the same function is not found during iteration, delete the exported function information in the binary intermediate file.

[0080] After the above processing, after traversing the export function information of all binary intermediate files, the export segment only contains information other than the function name in the export function information that appears in the conversion configuration information. This remaining information can be used as the export segment information of the converted binary loadable file.

[0081] Step 207: Convert the intermediate binary file to be converted according to the conversion auxiliary file to obtain the binary link file corresponding to the binary loadable file.

[0082] This step mainly involves deriving functions configured to be externally callable. Specifically, an export function information table for the binary intermediate file to be converted can be generated based on the binary intermediate file to be converted. Then, based on the export function information table for the binary intermediate file to be converted and the conversion configuration information corresponding to the binary intermediate file identifier, a binary link file corresponding to the converted loadable binary file can be generated.

[0083] The information table for exporting functions from the intermediate binary file to be converted can be found in the steps described above, and will not be repeated here.

[0084] When generating a binary link file, you can first determine the intersection of the exported function table of the binary intermediate file to be converted and the exported functions in the conversion configuration information corresponding to the binary intermediate file identifier; then determine the exported function information of the converted binary loadable file based on the exported functions in the intersection; finally, add the exported function information to the binary link file to obtain the binary link file corresponding to the converted binary loadable file.

[0085] It should be noted that the binary linker specifies which functions can be called externally, and this information is pre-configured in the conversion configuration information. The intersection of the exported functions in the conversion configuration information and the exported function table of the intermediate binary file to be converted is the set of functions that can be added to the binary linker for external use.

[0086] Example 3

[0087] Figure 3 This is a flowchart of a method for converting and generating a binary loadable file according to Embodiment 3 of the present invention. This embodiment describes the conversion and generation process when the target binary intermediate file is in an unlinked state. Figure 3 As shown, the method includes:

[0088] Step 301: Determine the target binary intermediate file and conversion configuration information as conversion auxiliary files.

[0089] In this embodiment, for unlinked target binary intermediate files, the target binary intermediate files and conversion configuration information can be used for conversion.

[0090] Step 302: Generate an import function information table for the binary intermediate file to be converted based on the import segment of the binary intermediate file to be converted.

[0091] As can be seen from the foregoing embodiments, the import segment of the binary intermediate file to be converted stores several import function information entries. Each import information entry records the name of the binary intermediate file to be converted, the function name, and the function signature information index. This step can generate an import function information table for the binary intermediate file to be converted based on the information in the import segment.

[0092] The table containing the import function information for the binary intermediate file to be converted includes multiple entries for import functions of the binary intermediate file to be converted. Each entry includes the following items:

[0093] The name of the binary intermediate file to which the imported function belongs in the import segment of the binary intermediate file to be converted, the name of the imported function in the import segment of the binary intermediate file to be converted, the number of input parameters of the imported function in the type segment of the binary intermediate file to be converted, and the number of return values ​​of the imported function in the type segment of the binary intermediate file to be converted.

[0094] Step 303: Generate the target binary intermediate file export function information table based on the export segment, type segment, and configuration information file of the target binary intermediate file in the conversion auxiliary file.

[0095] In this step, the target binary intermediate file export function information table includes multiple target binary intermediate file export function information entries. Each target binary intermediate file export function information entry includes the following table entries:

[0096] The target binary intermediate file name, target binary intermediate file version, target binary intermediate file AID, target binary intermediate file exported function name, target binary intermediate file exported function index, target binary intermediate file exported function input parameters, and target binary intermediate file exported function return value.

[0097] It should be noted that since the information stored in the export and type sections of the target binary intermediate file is limited, it can be merged with the corresponding exported function information in the configuration information file.

[0098] The configuration information file is the configuration information file corresponding to the target binary intermediate file.

[0099] Step 304: Generate the export function information table of the binary intermediate file to be converted based on the export segment of the binary intermediate file to be converted.

[0100] In this step, the exported segment of the intermediate binary file to be converted contains the function name and function index of the exported function. Based on this index, the signature information and bytecode of the exported function can be found.

[0101] Based on the information from this exported segment, an export function information table for the binary intermediate file to be converted can be generated. This export function information table includes multiple export function information entries for the binary intermediate file to be converted, and each export function information entry includes the following table entries:

[0102] The names of the exported functions in the exported segment of the binary intermediate file to be converted, and the indexes of the exported functions in the binary intermediate file to be converted.

[0103] Step 305: Based on the export function table of the target binary intermediate file and the import function table of the binary intermediate file to be converted, convert the import segment of the binary intermediate file to be converted to obtain the import segment information of the converted binary loadable file.

[0104] In this step, since the binary intermediate file import function information table contains multiple binary intermediate file import function entries, this step can iterate through the binary intermediate file import function information one by one based on the order in the table. When any binary intermediate file import function entry is encountered, the following processing is performed on that binary intermediate file import function entry:

[0105] For any binary intermediate file import function information in the import function table of the binary intermediate file to be converted, traverse the export function information table of all target binary intermediate files.

[0106] For each target binary intermediate file, the export function table information is traversed, and the name of the target binary intermediate file in the export function table information is compared with the name of the binary intermediate file in the binary intermediate file import function information.

[0107] If they are different, iterate through the next target binary intermediate file export function table information; if they are the same, end the iteration and replace the AID of the target binary intermediate file corresponding to the binary intermediate file identifier in the target binary intermediate file export function table information with the import module information corresponding to the import section in the binary intermediate file to be converted.

[0108] After traversing through all the binary intermediate file import function information in the import function table of the binary intermediate file to be converted, the duplicate import information in each import segment of the converted import segment is removed to obtain the import segment information of the converted binary loadable file.

[0109] Step 306: Based on the export function information table of the binary intermediate file to be converted and the export function information in the corresponding conversion configuration information of the binary intermediate file to be converted, convert the export segment of the binary intermediate file to be converted to obtain the export segment information of the converted binary loadable file.

[0110] The conversion of the exported segment is mainly based on the exported function information table of the binary intermediate file to be converted and the exported function information in the corresponding conversion configuration information of the binary intermediate file to be converted.

[0111] Specifically, the binary intermediate file export function information in the binary intermediate file export function information table to be converted is traversed one by one. For each binary intermediate file export function information encountered, the following processing is performed:

[0112] For any binary intermediate file export function information in the binary intermediate file export function information table to be converted, the export function information in the conversion configuration information corresponding to the binary intermediate file to be converted is traversed; for each binary intermediate file to be converted, the function name in the conversion configuration information corresponding to the binary intermediate file to be converted is compared with the function name in the binary intermediate file export function information.

[0113] If the same function is found during iteration, delete the function name from the exported information in the exported segment of the binary intermediate file; if the same function is not found during iteration, delete the exported function information in the binary intermediate file.

[0114] After the above processing, after traversing the export function information of all binary intermediate files, the export segment only contains information other than the function name in the export function information that appears in the conversion configuration information. This remaining information can be used as the export segment information of the converted binary loadable file.

[0115] Step 307: Convert the intermediate binary file to be converted based on the conversion auxiliary file to obtain the binary link file corresponding to the binary loadable file.

[0116] This step mainly involves deriving functions configured to be externally callable. Specifically, an export function information table for the binary intermediate file to be converted can be generated based on the binary intermediate file to be converted. Then, based on the export function information table for the binary intermediate file to be converted and the conversion configuration information corresponding to the binary intermediate file identifier, a binary link file corresponding to the converted loadable binary file can be generated.

[0117] When generating a binary link file, first determine the intersection of the exported function table of the binary intermediate file to be converted and the exported functions in the conversion configuration information corresponding to the binary intermediate file identifier; then determine the exported function information of the converted binary loadable file based on the exported functions in the intersection; finally, add the exported function information to the binary link file template file and calculate the checksum to obtain the binary link file corresponding to the converted binary loadable file.

[0118] It should be noted that the binary linker specifies which functions can be called externally, and this information is pre-configured in the conversion configuration information. The intersection of the exported functions in the conversion configuration information and the exported function table of the intermediate binary file to be converted is the set of functions that can be added to the binary linker for external use.
