Encoding method and decoding method for function calling context, and apparatus

A decoding method for a function calling context, comprising:

• obtaining an encoding result of a calling context of a target function;
• obtaining encoding values corresponding to creation relationships between a plurality of threads in program code, wherein the program code comprises the target function;
• obtaining encoding values corresponding to call relationships between a plurality of functions in the plurality of threads in the program code;
• and
• decoding the encoding result of the calling context of the target function based on the encoding values corresponding to the creation relationships between the plurality of threads in the program code and the encoding values corresponding to the call relationships between the plurality of functions in the plurality of threads in the program code, to obtain a function call string of the target function.

An encoding apparatus for a function calling context, comprising a processor and a memory, wherein the memory is configured to store program instructions, and the processor is configured to invoke the program instructions to perform the method comprising:

• obtaining calling context information of a target function;
• obtaining encoding values corresponding to creation relationships between a plurality of threads in program code, wherein the program code comprises the target function;
• and
• encoding, based on the calling context information of the target function and the encoding values corresponding to the creation relationships between the plurality of threads, a context of a thread to which the target function belongs, to obtain an encoding result of the context of the thread to which the target function belongs.

A decoding apparatus for a function calling context, comprising a processor and a memory, wherein the memory is configured to store program instructions, and the processor is configured to invoke the program instructions to perform operations comprising:

• obtaining an encoding result of a calling context of a target function;
• obtaining encoding values corresponding to creation relationships between a plurality of threads in program code, wherein the program code comprises the target function;
• obtaining encoding values corresponding to call relationships between a plurality of functions in the plurality of threads in the program code;
• and
• decoding the encoding result of the calling context of the target function based on the encoding values corresponding to the creation relationships between the plurality of threads in the program code and the encoding values corresponding to the call relationships between the plurality of functions in the plurality of threads in the program code, to obtain a function call string of the target function.
