The embodiment of the application discloses a memory recycling method and system for a compiled language and a computer readable storage medium. The method comprises the following steps: scanning a to-be-recycled memory object node, determining a garbage collection analysis batch and a node entry edge access frequency of the to-be-recycled memory object node according to a uniform bitmap page manager; accumulating the node entry edge access frequency of the to-be-recycled memory object nodes in the same garbage collection analysis batch, judging the relationship between the accumulated node entry edge access frequency and the smart pointer reference count of each node in the batch, and determining the object node to be recycled according to the relationship between the node entry edge access frequency and the smart pointer reference count; and releasing the memory of the object node. The embodiment of the application realizes the recyclable management of the life cycle of a business object without changing the memory layout of the business object, and solves the problem of circular reference.

The embodiment of the invention discloses a compiling language-oriented memory recovery method and system and a computer readable storage medium. The method comprises the following steps: scanning a to-be-recycled memory object node, and determining a garbage recycling analysis batch and a node edge access frequency of the to-be-recycled memory object node according to a unified bitmap page manager; for the to-be-recycled memory object nodes in the current same garbage recycling analysis batch, accumulating the node edge access times, and judging the relationship between the accumulated node edge access times of each node in the batch and the intelligent pointer reference count; determining an object node to be subjected to memory recovery according to the relationship between the node edge access times and the intelligent pointer reference count; and performing memory release on the object node. According to the embodiment of the invention, on the premise that the memory layout of the business object is not changed, recoverable management of the life cycle of the business object is realized, and the problem of circular reference is solved.

This application relates to an inline hooking method and apparatus for compiled languages. The method includes: responding to a received inline hooking request, determining the size of the target function to be inline hooked; determining whether the target function can be inline hooked based on the size of the target function and the difference between the address of the hook function and the address of the target function; a hook function, a function used to execute the functionality of the target function by calling a jump function; when it is determined that the target function can be inline hooked, copying the instruction code of the target function to a preset memory area, and revising the content of the copied instruction code to obtain the jump function of the target function; writing a target jump instruction at the beginning of the target function, and using the target jump instruction to redirect the call to the target function to the hook function. This method solves the problem that existing inline hooking methods are not applicable to compiled languages.
