Detailed ways

In order to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, in the case of no conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways than described here; obviously, the embodiments in the description are only some of the embodiments of the present disclosure, and Not all examples.

Fig. 1 is a flow chart of a symbol analysis method provided by an embodiment of the present disclosure, which can be executed by a computer device; and processing power equipment. As shown in FIG. 1 , the log file parsing method provided by the embodiment of the present disclosure includes steps S101-S103.

S101: Receive a log file of an application program, where the log file includes a first file address of an inline function.

In an application of an embodiment of the present disclosure, the application program may be an application program running on the client device; when the application program appears to be in abnormal situations such as flashback or freezing, the method or method executed by the application program when the client device encounters a problem The address of the function is recorded in the log file. The aforementioned client device is connected in communication with the computer device used to analyze the log file, and the client device sends the log file through a communication link (which can be a wired communication link or a wireless communication link) with the computer To the computer device; after the computer device receives the log file of the application program, it can analyze the log file.

In the embodiment of the present disclosure, the log file includes the first file address of the inline function. Among them, an inline function (sometimes called an online function or a compile-time expansion function) is a programming language construct used to suggest that the compiler perform inline expansion (sometimes called an online expansion) for some special functions; The compiler inserts the specified function body into and replaces every call to the function. In the program source code, the inline function marked by the keyword inline is generally used.

In an implementation manner of the embodiment of the present disclosure, the first file address of the inline function may refer to the address of the source file of the inline function. At this time, the pre-expanded position information and the expanded position information of the inline function may be searched directly in the preset symbol table based on the address of the first file.

In another implementation manner of the embodiment of the present disclosure, the first file address of the inline function may include a stack address stack_address and a load address load_address of the inline function. In this implementation, you can first subtract load_address from stack_address to get the offset address of the inline function, and then add the offset address to the start address of the inline function (usually a known fixed value) to get the target address . Further, the preset symbol table is searched based on the target address to obtain the position information of the inline function before expansion and the position information after expansion.

S102: Based on the first file address, search a preset symbol table to obtain information about a first position and information about a second position of the inline function in the application source code.

The corresponding relationship between the file address of the function (ie, the address of the source file) and the symbol is stored in the symbol table, where the symbol can include the line number of the source code, the name of the function, and the name of the file. When the function is an inline function, the symbols in the symbol table include the line number and file name before the inline function is expanded, and the line number, file name, and function name after the inline function is expanded.

Searching the symbol table based on the address of the first file can obtain the first position information and the second position information of the inline function in the source program code.

The first location information is information about a location before the inline function is expanded, and specifically may be information about a location when the inline function is declared or defined.

The second location information is information about the location after the inline function is expanded, for example, it may be information about the location when the inline function is called in the application source code.

In an application of an embodiment of the present disclosure, the preset symbol table may include application debugging information and source code segment information, wherein the application debugging information includes the address of the source file of the inline function and the expansion of the inline function The mapping relationship between the information of the expanded position. The information of the expanded position may include, for example, the line number, function name, and file name corresponding to the expanded position. The source code segment information includes the address of the source file of the inline function and the inline The mapping relationship between the information of the position before the expansion of the linked function, the information of the position before the expansion may include, for example, the line number and file name corresponding to the position before the expansion; correspondingly, based on the address of the first file, from the symbol table Acquiring the information of the first position and the information of the second position of the inline function in the application source code may include steps S1021-S1022.

S1021: Based on the address of the first file, obtain the information of the first location by searching the information of the source code segment.

S1022: Obtain second location information by searching from the debugging information based on the first file address.

In a specific application of the disclosed embodiment, the symbol table may specifically be a file in DWARF (Debugging with Attributed Record Formats) format.

In the DWARF format symbol table, the source code segment information is stored in the debug_line_section of the DWARF format file.

The mapping relationship between the address of the source file of the inline function and the location of the source code is stored in the debug_line_section, for example, the following table shows an exemplary mapping relationship between the address and the location of the source code.

If the first file address obtained in step S101 is specifically the address of the source file of the inline function, the first file address is 0x0000000100006404, based on the aforementioned table, it is determined that the first position of the inline function in the application source code is located in the file Line 12 of the file labeled 1.

Further, by searching the information of the "file_names" entry in the debug_line_section, the file name before the expansion of the inline function can be obtained.

In the symbol table of the DWARF format, the debug information is stored in the debug_info_section. In this case, the second location information obtained from the debug information based on the first file address can be specifically: find the first file address from the debug_info_section (here Assuming that the first file address is specified as the address of the source file of the inline function, in the case where the first file address includes the stack address and the load address, the corresponding source file address needs to be calculated according to the stack address and the load address) The tag of DW_TAG_inlined_subroutine is the import of the source code information segment (The Debugging Information Entry, DIE for short), and then find the expanded second position information corresponding to the inline function in the import of the source code information segment.

For example, if the address of the first file obtained in step S101 is 0x0000000100006404, the entry of the corresponding source code information segment is found as follows.

0x0005ecd2:DW_TAG_inlined_subroutine

DW_AT_abstract_origin (0x0005ec41 "Add")

DW_AT_low_pc (0x00000001000063fc)

DW_AT_high_pc (0x0000000100006408)

DW_AT_call_file("/Users/fengyadong/work/project

/inlinetest/inlinetest/main.c")

DW_AT_call_line(20)

Analyze the import of the aforementioned source code information section, and determine that the file name after the inline function is expanded is "main.c", and the line number after the inline function is expanded is 20, so the information at the second position is the file name " main.c" on line 20 of the application source code.

Further, the address of the first file can also be obtained from the debug_info_section (here, it is assumed that the address of the first file is specified as the address of the source file of the inline function, and in the case that the address of the first file includes the stack address and the load address, The corresponding source file address needs to be calculated according to the stack address and loading address) The corresponding label is DW_TAG_subprogram DIE to find the content corresponding to the "DW_AT_name" label, and the content corresponding to the "DW_AT_name" label is the function name after the expansion of the inline function .

S103: Display the information of the first location and the information of the second location.

In the symbol parsing method provided by the embodiment of the present disclosure, when the received log file includes the first file address of the inline function, the first file address of the inline function is searched from the preset symbol table to obtain the inline function in the application. The information of the first position before the program source code is expanded and the second information of the expanded position, and the information of the first position and the information of the second position are displayed.

The analysis method provided by the embodiments of the present disclosure can accurately determine the position of the inline function before and after expansion in the application source code, thereby helping technicians to determine the actual position of the fault faster and more accurately. Improve the efficiency and accuracy of fault analysis.

In still another embodiment of the embodiment of the present disclosure, the wrong line number parsed from the symbol table may also be corrected. For example, in an example, the mapping relationship between the address of the source file stored in the debug_line_section and the line number can be expressed as follows.

The address 0x0000000100006404 corresponds to line 0 in the application source code, and this correspondence is obviously unreasonable, that is, this correspondence is wrong.

In order to solve the foregoing problems, in some applications of the embodiments of the present disclosure, the information of the first location includes a line number, and before step S103 is performed, step S104 is further included: in response to the line number matching the preset error line number, Then correct the line number to the line number corresponding to the second file address included in the source code segment information.

In step S104, the second file address is the closest to the first file address in the source code segment information, corresponds to a breakpoint location, and has an address smaller than the first file address.

Refer to the above table, it is closest to 0x0000000100006404 and corresponds to a breakpoint location, the address of the address less than 0x0000000100006404 is 0x00000001000063fc; therefore, change the line number corresponding to 0x0000000100006404 from 0 to the line corresponding to 0x00000001000063fc.

In still another embodiment of the disclosed embodiment, the computer device also stores the source code of the application program in addition to storing the preset symbol table. In the previous case, in an application of the present disclosure, step S103 displays the information of the first location and the information of the second location, which may specifically include S1031: displaying the source code of the application, and The first position and the second position are marked in the code.

FIG. 2 is a schematic diagram showing information of a first location and information of a second location according to an embodiment of the present disclosure. As shown in Figure 2, the source code of the application program main.c is shown, and each line of the program code is marked; the information to determine the first position is the 12th line in main.c, and the second After the position information is the 20th line in main.c, the program codes of the 12th line and the 20th line are highlighted at the same time to reflect the first position and the second position.

In a specific application of the embodiment of the present disclosure, after step S1031 is performed, step S105 may be further included: displaying the source file of the inline function in response to the first trigger operation for the second location.

In a specific application, when the first trigger operation for the second location is received, a pop-up window may be generated, and the source file of the pre-obtained inline function is displayed in the pop-up window.

In some applications of the embodiments of the present disclosure, after step S1031 is performed, step S106 may also be included: jumping the display position to the first position in response to the second trigger operation for the second position; or responding Based on a third trigger operation on the first position, jumping the display position to the second position.

In some applications of the present disclosure, if the second trigger operation for the second location is received, the current display location is jumped to the first location to realize the display of the program source code at the first location; similarly, if a For the third trigger operation on the first position, the current display position is jumped to the second position. In this way, the user can switch between the first position and the second position without performing a pull-down operation or a page-turning operation, and quickly find the corresponding application source code field.
