Description
Technical Field
The present invention relates to the field of computer technologies, and in particular, to an information processing method and apparatus, a storage medium, and a processor.
Background
At present, after application software is developed, the application software needs to be compiled and debugged, for example, for the problem of application program segment errors and the like, the compilation is usually signed. In normal signed compilation, debug symbols will exist with the object code, possibly resulting in redundancy of the symbol table. For example, a CPP file includes a plurality of header files, and the debug information of each header file is stored in a plurality of object codes. This redundancy is further amplified during the linking stage, e.g., the same library may exist in multiple programs, each with a complete copy of the debug symbol. This leads to the following two problems: first, a problem of compiling, that is, many files are included in a plurality of programs or even in each final program for more complete code testing at the time of compiling, especially, basic library files, results in a large amount of repeated data in a symbol table, such as correspondence between symbols and files. By analyzing some programs, it was found that the file sizes containing symbols and removed symbols differ by a factor of 10. Secondly, the issue is a problem that the issue fails due to too large issue packages in the process of issuing the object code. To circumvent this problem, symbols are usually removed entirely in the related art. The full program content is stored in the release repository. When each project file is frequently called, a large amount of extra storage cost needs to be paid for this.
To solve the problem, the related art proposes two solutions, namely firstly, no symbol table is generated during compiling, and the option of generating the symbol table by a compiler is closed to avoid the influence of the symbol table on the size of the program, but the problem is that the complexity of debugging the program is very high, and normal debugging cannot be carried out when the program is abnormal, such as an application program segment error.
In view of the above problems, no effective solution has been proposed.

Under the above operating environment, the present application provides an information processing method as shown in fig. 2. Fig. 2 is a flowchart of an information processing method according to a first embodiment of the present invention.
Step S101, compiling a source code, and storing a compiled symbol table into a symbol database, wherein the symbol table is used for recording debugging information between the source code and a program corresponding to the source code.
The program described above may be a binary program. It should be noted that, in the information processing method provided in the embodiment of the present application, only necessary logic related to executable code is in the object code during compiling, and other debugging information that should be stored together with the object code is stored in the symbol database.
Step S102, based on the position information of the symbol table in the symbol database, determining the index information of the symbol table.
Step S103, generating a distribution file of the program based on the compiled object code and the index information of the symbol table.
The release file is a software package that can be directly installed. For example, an installation package with the format of. apk. Through the steps, the index information of the symbol table and the target code are separated to generate the release file, and the corresponding symbol table in the release file is associated by the index information, so that the size of the file of the target code generated during compiling can be greatly reduced, and the size of the generated release file can be remarkably reduced. On the other hand, according to the embodiment of the application, a complete symbol table can be reconstructed according to the index information, and problem debugging is not affected.
According to the information processing method provided by the embodiment of the application, a symbol table and an object code are separated, a source code is compiled, and the compiled symbol table is stored in a symbol database, wherein the symbol table is used for recording debugging information between the source code and a program corresponding to the source code; determining index information of the symbol table based on the position information of the symbol table in the symbol database; the method and the device have the advantages that the release file of the program is generated based on the index information of the compiled object code and the symbol table, the fine granularity separation of the object code and the debugging information of the application program is achieved, and the debugging information is free of redundancy, so that the technical effect of greatly reducing the size of the file of the object code generated during compiling is achieved, and the technical problem that the object code generated during compiling of the source code in the related technology carries redundant debugging information is solved.
In the information processing method provided in the embodiment of the present application, storing the compiled symbol table in the symbol database includes: judging whether debugging information exists in the symbol database; if the target information in the debugging information exists in the symbol database, carrying out duplicate removal processing on the target information in the debugging information; and storing the debugging information after the deduplication processing into a symbol database.
In order to reduce the size of the symbol database, all repeated symbols are deduplicated, according to the scheme, if the information in the compiled symbol table exists in the symbol database, the repeated part is deduplicated, and the unrepeated part is stored in the symbol database.
It should be noted that besides symbols, some unsigned data that can be reused, such as a large amount of inline code, whose code segment mapping relationship with file name and line number is also decompressed. The symbol database is not affiliated to any specific executable program or compiling unit, so any redundant information can be reduced into one entity data and a plurality of index information, and the space occupation of the symbol database is greatly reduced.
In order to reduce the size of the symbol database, only one copy of repeated data in the symbol table is recorded, and in order to ensure that the information in the index table corresponding to the target code is complete, the deduplication processing of the target information in the debug information in the application includes: determining index information of target information in the debugging information in a symbol database; replacing the target information with index information of the target information in the symbol table; and taking the debugging information in the symbol table after replacement as the debugging information after the deduplication processing.
For example, if the information of a-to-B in the index table exists in the symbol database, and if the 2 nd segment of page 3, numbered 3002 exists, the index table is replaced with "3002". And the processed index table is stored in the symbol database, so that the size of the symbol database is further reduced.
Optionally, in the information processing method provided in the embodiment of the present application, the method further includes: after generating a release file of a program based on the compiled generated target code and the index information of the symbol table, acquiring debugging information corresponding to the program from the symbol database through the index information of the symbol table; reconstructing a symbol table based on the acquired debugging information; and debugging the program by adopting the reconstructed symbol table.
Through the scheme, the symbol table of a certain program can be reconstructed, and the symbol table file can be created according to the standard format of the symbol table according to the content recorded in the symbol database for debugging.
Optionally, in the information processing method provided in the embodiment of the present application, the method further includes: detecting whether a plurality of versions of a program exist after generating a distribution file of the program based on the compiled generated object code and index information of the symbol table; if a plurality of versions exist, determining index information in symbol tables of release files of the programs of the plurality of versions; determining a shared symbol table from a symbol database based on index information in symbol tables of distribution files of a plurality of versions of programs; and determining the index information of the shared symbol table based on the position information of the shared symbol table in the symbol database, so that the release files of the programs of multiple versions share the shared symbol table through the index information of the shared symbol table.
Through the scheme, further deduplication is realized, most codes are not changed in the software iteration process, and the same symbol table information can be shared among different software versions for the same part, so that the occupied space of the symbol database is further compressed.
It should be noted that, for simplicity of description, the above-mentioned method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the order of acts, as some steps may occur in other orders or concurrently in accordance with the invention.

Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (such as ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (such as a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.
