[0026] Embodiment 1

[0027] Figure 1 A flowchart of a method for converting and generating a binary loadable file is provided for the first embodiment of the present invention. This embodiment is applicable to the conversion and generation of a binary loadable file. The method can be executed by a binary loadable file conversion and generation device. The binary loadable file conversion and generation device can be implemented in the form of hardware and / or software. The binary loadable file conversion and generation device 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, a conversion auxiliary file is obtained based on 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. An application combination can use the API functions provided by the system or the API functions of other application combinations.

[0030] In this embodiment, the 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 file 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] Among them, the import segment 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 the import segment can be determined as the required binary intermediate file identifier.

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

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

[0035] If the link status indicates that the target binary intermediate file is in a linked state, a target binary link file corresponding to the target binary intermediate file is obtained, and the target binary link file is determined as a conversion auxiliary file.

[0036] If the link status indicates that the target binary intermediate file is in an unlinked state, the target binary intermediate file and the conversion configuration information are determined as conversion auxiliary files.

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

[0038] In addition, 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 binary intermediate file identifier to be converted, the module information and export function information converted into the binary loadable file, the module information includes: the module version, the module AID length and the module AID, and the export function information includes: the name of the export function of the binary intermediate file to be converted.

[0039] Step 102: convert the binary intermediate file to be converted according to the conversion auxiliary file to obtain the import segment information and export segment information in the converted binary loadable file, and the binary link file corresponding to the binary loadable file.

[0040] In this step, the import segment in the binary intermediate file is mainly converted, 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 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, and 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 the export segment information in the converted binary loadable file, and the binary link file corresponding to the binary loadable file; the conversion auxiliary file is used to realize the conversion of the binary intermediate file, and the import segment information and the export segment information of the binary loadable file, and the corresponding binary link file are obtained. For multiple binary intermediate files, the scheme of the present invention can still be implemented simultaneously, thereby improving the conversion efficiency; the transformation of the import segment of the binary intermediate file completes the link between multiple binary intermediate files, reduces the secondary link process required for subsequent installation, and improves the installation speed.

[0043] Embodiment 2

[0044] Figure 2 This is a flow chart of a method for converting and generating a binary loadable file provided in the second embodiment of the present invention. This embodiment is a process of converting and generating a target binary intermediate file when the target binary intermediate file is in a linked state. Figure 2 As shown, the method includes:

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

[0046] After the link status of the target binary intermediate file is determined in the foregoing embodiment, the present embodiment is in a linked state. Therefore, the target binary link file corresponding to the target binary intermediate file can be obtained and the target binary link file can be determined as a conversion auxiliary file.

[0047] That is to say, 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 may also be verified.

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

[0050] Among them, each target segment can include but is not limited to: magic, version, module_name_size, module_name, module_aid_size, module_aid, export_function_count, functions fields, and these fields are used as binary link file template files.

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

[0052] In this step, the target binary link file contains multiple export functions and related information, so the export functions and related information can be extracted to generate a binary link file export function information table.

[0053] The binary link file export function information table may contain multiple binary link file export function information, each binary link file export function information includes the following table items:

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

[0055] It should be noted that AID is an application identifier (Application Identifier). For the specific definition of the above table items, please refer to the relevant technology and will not be repeated here.

[0056] Step 203: Generate a binary intermediate file to be converted import function information table according to the binary intermediate file to be converted import segment.

[0057] It can be seen from the above embodiments that a number of import function information are stored in the import segment of the binary intermediate file to be converted, and each import information records the name of the binary intermediate file of the imported function, the function name, and the function signature information index. This step can generate an import function information table of the binary intermediate file to be converted based on the information of the import segment.

[0058] The binary intermediate file import function information table to be converted includes multiple pieces of binary intermediate file import function information to be converted, and each piece of binary intermediate file import function information to be converted includes the following table items:

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

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

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

[0062] Based on the information of the export segment, a binary intermediate file export function information table to be converted can be generated, and the binary intermediate file export function information table to be converted includes multiple binary intermediate file export function information to be converted, and each binary intermediate file export function information to be converted includes the following table items:

[0063] The name of the export function in the export segment of the binary intermediate file to be converted and the export function index of the binary intermediate file to be converted.

[0064] Step 205: According to the binary link file export function information table and the binary intermediate file import function information table to be converted, the import segment of the binary intermediate file to be converted is converted to obtain the import segment information of the converted binary loadable file.

[0065] In this step, when converting the import segment, it is mainly based on the binary link file export function information table and the to-be-converted binary intermediate file import function information table.

[0066] Since the binary intermediate file import function information table to be converted contains multiple pieces of binary intermediate file import function information, this step can traverse the binary intermediate file import function information one by one based on the order in the binary intermediate file import function information table to be converted. When traversing to any piece of binary intermediate file import function information, the following processing is performed for the piece of binary intermediate file import function information:

[0067] For any binary intermediate file import function information in the binary intermediate file import function information table to be converted, all the acquired binary link file export function information tables are traversed; each time a binary link file export function information in the binary link file export function information table is traversed, it is determined whether the name of the target binary intermediate file in the binary link file export function information is the same as the binary intermediate file name of the binary intermediate file import function information.

[0068] If they are not the same, traverse the next binary link file export function information; if they are the same, end the traversal, and replace the import module information corresponding to the import segment in the binary intermediate file to be converted with the AID of the target binary intermediate file corresponding to the binary intermediate file identifier in the binary link file export function information.

[0069] It should be noted that when traversing the above-mentioned export function information tables of all acquired binary link files, as long as the name of the target binary intermediate file that is the same as the binary intermediate file name of the binary intermediate file import function information is traversed, the traversal of the binary link file export function information table can be terminated.

[0070] Then, the traversed binary link file export function information having the same name as the target binary intermediate file is used as the data basis for conversion, and the binary intermediate file import function information is converted.

[0071] The specific conversion is to replace the AID of the target binary intermediate file corresponding to the binary intermediate file identifier in the binary link file export function information with the import module information corresponding to the import segment in the binary intermediate file to be converted, so that only the aforementioned AID is stored in the import module information.

[0072] After the replacement is completed, the next binary intermediate file import function information is processed.

[0073] After traversing all the binary intermediate file import function information in the binary intermediate file import function information table to be converted, the import information in the converted import segment is deduplicated to obtain the import segment information of the converted binary loadable file.

[0074] It should be noted that after the conversion is completed, the same AID may exist in each piece of imported information. In this case, deduplication is performed to keep only one piece of the same AID.

[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 export segment is mainly based on 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.

[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, and each time a piece of binary intermediate file export function information is traversed, the binary intermediate file export function information is processed as follows:

[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; each time the export function information in the conversion configuration information corresponding to the binary intermediate file to be converted is traversed, it is determined whether the function name in the export function information in the conversion configuration information corresponding to the binary intermediate file to be converted is the same as the function name in the binary intermediate file export function information.

[0079] If the traversal finds the same, delete the function name in the export information in the export segment of the binary intermediate file; if the traversal does not find the same, delete the export function information in the binary intermediate file.

[0080] Based on the above processing, after completing the traversal of the export function information of all binary intermediate files, the export segment only contains other information except the function name in the export function information appearing in the conversion configuration information. The remaining information can be used as the export segment information of the converted binary loadable file.

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

[0082] In this step, the main purpose is to obtain the function that is configured to be called externally. Specifically, an export function information table of the binary intermediate file to be converted can be generated based on the binary intermediate file to be converted; then, a binary link file corresponding to the converted binary loadable file can be generated based on the conversion configuration information corresponding to the export function information table of the binary intermediate file to be converted and the binary intermediate file identifier.

[0083] Among them, the export function information table of the binary intermediate file to be converted can refer to the above steps and will not be repeated here.

[0084] When generating a binary link file, the intersection of the export function table of the binary intermediate file to be converted and the export function in the conversion configuration information corresponding to the binary intermediate file identifier can be first determined; then the export function information of the converted binary loadable file is determined based on the export function in the intersection; finally, the export function information is added 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 link file specifies which functions can be called externally, and this information will be pre-configured in the conversion configuration information. The intersection of the export function of the conversion configuration information and the export function table of the binary intermediate file to be converted is the function that can be added to the binary link file for external calls.

[0086] Embodiment 3

[0087] Figure 3 This is a flowchart of a method for converting and generating a binary loadable file provided in Embodiment 3 of the present invention. This embodiment is a process for converting and generating a target binary intermediate file 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 an unlinked target binary intermediate file, the target binary intermediate file and the conversion configuration information may be used to perform conversion.

[0090] Step 302: Generate a binary intermediate file to be converted import function information table according to the binary intermediate file to be converted import segment.

[0091] It can be seen from the above embodiments that a number of import function information are stored in the import segment of the binary intermediate file to be converted, and each import information records the name of the binary intermediate file of the imported function, the function name, and the function signature information index. This step can generate an import function information table of the binary intermediate file to be converted based on the information of the import segment.

[0092] The binary intermediate file import function information table to be converted includes multiple pieces of binary intermediate file import function information to be converted, and each piece of binary intermediate file import function information to be converted includes the following table items:

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

[0094] Step 303: Generate a target binary intermediate file export function information table according to 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, and each target binary intermediate file export function information includes the following table items:

[0096] The name of the target binary intermediate file, the version of the target binary intermediate file, the AID of the target binary intermediate file, the name of the export function of the target binary intermediate file, the export function index of the target binary intermediate file, the number of input parameters of the export function of the target binary intermediate file, and the number of return values ​​of the export function of the target binary intermediate file.

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

[0098] Among them, the configuration information file is the configuration information file corresponding to the target binary intermediate file.

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

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

[0101] Based on the information of the export segment, a binary intermediate file export function information table to be converted can be generated, and the binary intermediate file export function information table to be converted includes multiple binary intermediate file export function information to be converted, and each binary intermediate file export function information to be converted includes the following table items:

[0102] The name of the export function in the export segment of the binary intermediate file to be converted and the export function index of the binary intermediate file to be converted.

[0103] Step 305: convert the import segment of the binary intermediate file to be converted according to the target binary intermediate file export function table and the binary intermediate file to be converted import function table 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 to be converted contains multiple binary intermediate file import function information, this step can traverse the binary intermediate file import function information one by one based on the order in the binary intermediate file import function information table to be converted. When traversing to any binary intermediate file import function information, the following processing is performed for the binary intermediate file import function information:

[0105] For any piece of binary intermediate file import function information in the binary intermediate file import function table to be converted, all acquired target binary intermediate file export function information tables are traversed.

[0106] Each time the target binary intermediate file export function table information in the target binary intermediate file export function table information table is traversed, it is determined whether the name of the target binary intermediate file in the target binary intermediate file export function table information is the same as the binary intermediate file name in the binary intermediate file import function information.

[0107] If they are not the same, traverse the next target binary intermediate file export function table information; if they are the same, end the traversal, and replace the import module information corresponding to the import segment in the binary intermediate binary file to be converted with 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.

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

[0109] Step 306: convert the export segment of the binary intermediate file to be converted 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.

[0110] The conversion of the export segment is mainly based on 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.

[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, and each time a piece of binary intermediate file export function information is traversed, the binary intermediate file export function information is processed as follows:

[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; each time the export function information in the conversion configuration information corresponding to the binary intermediate file to be converted is traversed, it is determined whether the function name in the export function information in the conversion configuration information corresponding to the binary intermediate file to be converted is the same as the function name in the binary intermediate file export function information.

[0113] If the traversal finds the same, delete the function name in the export information in the export segment of the binary intermediate file; if the traversal does not find the same, delete the export function information in the binary intermediate file.

[0114] Based on the above processing, after completing the traversal of the export function information of all binary intermediate files, the export segment only contains other information except the function name in the export function information appearing in the conversion configuration information. The remaining information can be used as the export segment information of the converted binary loadable file.

[0115] Step 307: convert the binary intermediate file to be converted according to the conversion auxiliary file to obtain a binary link file corresponding to the binary loadable file.

[0116] In this step, the main purpose is to obtain the function that is configured to be called externally. Specifically, an export function information table of the binary intermediate file to be converted can be generated based on the binary intermediate file to be converted; then, a binary link file corresponding to the converted binary loadable file can be generated based on the conversion configuration information corresponding to the export function information table of the binary intermediate file to be converted and the binary intermediate file identifier.

[0117] When generating a binary link file, the intersection of the export function table of the binary intermediate file to be converted and the export function in the conversion configuration information corresponding to the binary intermediate file identifier can be determined first; then the export function information of the converted binary loadable file is determined based on the export function in the intersection; finally, the export function information is added to the binary link file template file and the checksum is calculated to obtain the binary link file corresponding to the converted binary loadable file.

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