Embodiment
Scheme in the present invention is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.
Inventor finds through research, in the prior art shown in Fig. 1, in the process of execution first function, in order to complete the call instruction of the first function to each allocating object, need the address of each allocating object being searched the first function by the list structure of the first function.And the list structure of the first function needs to be searched by the table address of the first function.But, when first function call the second function, under the Article 1 instruction of the second function, equipment can jump to the 3rd function in patch file, in the implementation of the 3rd function, the table address of the first function can be lost, therefore, when the 3rd function execute return the first function time, in the implementation of the first function subsequent instructions, the list structure of the first function cannot find, first function subsequent instructions also just cannot realize calling allocating object, therefore, the operation of software will be broken down, thus causes the operation of software to occur interrupting.
In order to solve the problems referred to above of prior art, in embodiments of the present invention, patch file comprises the 3rd function, intermediate code and headspace, wherein, in intermediate code, for jump to the 3rd function the second call instruction before there is the instruction of the table address for preserving the first function and the instruction for the return address of preserving the first call instruction, there is after second call instruction the instruction of the table address for recovering the first function and the instruction for the return address of preserving the first call instruction, and, headspace is for the return address of the table address and the first call instruction of preserving the first function.Therefore, the table address of the first function lost when intermediate code calls the 3rd function, can recover from headspace executing before the 3rd function returns the first function, therefore, after returning the first function, in the process of execution first function subsequent instructions, the list structure of the first function can be searched, and the first function subsequent instructions also just can realize calling allocating object, thus the operation avoiding software is broken down, decrease the situation that interrupting appears in running software.In addition, although the return address of the first call instruction has been replaced by the return address of the second call instruction when intermediate code calls the 3rd function, but executing the return address that can recover the first call instruction before the 3rd function returns the first function from headspace and returning the first function accordingly, thus the operation avoiding software is broken down, decrease the situation that interrupting appears in running software.Again in addition, the table address of the first function and the return address of the first call instruction are kept in the headspace reserved in patch file, the table address preserved and return address can not change stack frame structure, thus avoid stack frame structure and change the acquisition of information mistake caused, and then avoid the running software that acquisition of information mistake causes and interrupt.As can be seen here, by the embodiment of the present invention, after patch file upgrades software, the many factors causing software interruption to be run are avoided, and therefore, the possibility that running software interrupts reduces greatly.
Below in conjunction with accompanying drawing, described in detail the implementation of the method, relevant device and the system that start the operating system in the present invention by embodiment.
See Fig. 2, show the schematic flow sheet of a kind of patch disposal route in the embodiment of the present invention.In the present embodiment, described method can be applied to the equipment of operating software, and described software is the software needing patch process, and described equipment can be such as communication facilities.The method such as specifically can comprise the steps:
S201, in response to execution to the first call instruction in the first function, jump to the second function.
Wherein, described first function can be the function of the process creation of software, as principal function.Second function described in described second by described first function call, also, can include the first call instruction for calling described second function in the instruction of described first function.Be understandable that, described second function is the function that software had had before loading patch file, and also, described second function is the original function of the non-patch of software.In the present embodiment, described patch process can be the update process of carrying out described second function.
When the process of equipment operating software, described equipment performs each instruction of described first function successively according to the instruction sequences of described first function.When performing in described first function for calling the first call instruction of described second function, described equipment jumps to described second function from described first call instruction of described first function, starts the instruction performing described second function according to the instruction sequences of described second function.
It should be noted that, when described equipment performs described first call instruction of described first function, before jumping to described second function, described processor the address of next instruction of the first call instruction described in described first function can be recorded as return address, so that can turn back to the instruction after the first call instruction described in described first function of described first function continuation execution after jumping to described second function.
S202, in response to performing the Article 1 instruction of described second function, jump to the intermediate code of patch file.
Described device responds in described first function described first call instruction and after jumping to described second function, perform the Article 1 instruction of described second function.After Bootload patch file, the Article 1 instruction of described second function is the call instruction of the intermediate code for calling described patch file.Described equipment performs the Article 1 instruction of described second function, and described equipment jumps to the intermediate code of described patch file from the Article 1 instruction of described second function, starts the instruction performing described intermediate code.Be understandable that, when described equipment performs the Article 1 instruction of described second function, the return address of described equipment record is constant.Also, namely, after described equipment jumps to described intermediate code, the return address of described equipment record is still the address of the address order of next instruction of the first call instruction described in described first function.Therefore, after patch file described in Bootload, the in fact no longer all instructions of executive software before not loading described patch file in described second function of described equipment, but perform the instruction in described patch file.
It should be noted that, in the process of Bootload to described patch file, needing can increase by one for calling the instruction of the code that described patch file provides, as the Article 1 instruction of described second function in described second function upgraded.After this, described equipment can jump to function that patch file provides and no longer perform original instruction of described second function when calling described second function, therefore, patch file just achieves the renewal to the second function.Particularly, in order to realize patch file described in Bootload, the present embodiment is as comprised: patch file as described in obtaining, and obtains the address of described second function according to described patch file; According to the address of described second function, in described second function, add the instruction for jumping to described intermediate code, as the Article 1 instruction of described second function.In a specific embodiment, mark or the address of described second function is recorded in described patch file.Described equipment can according to the mark of described second function in described patch file or address in the process described patch file being loaded into software, determine that described patch file is for upgrading described second function, and obtain the address of described second function.According to the address search of described second function to described second function, generate one for the instruction of strip to the intermediate code of described patch file, and this instruction is added to the Article 1 instruction of described second function as described second function.
S203, instruction according to described intermediate code, the return address of the table address of described first function and described first call instruction is saved in the headspace of described patch file, the table address of described first function is the address of the list structure of described first function, and the list structure of described first function is for recording the address of the allocating object of described first function.
Particularly, there is in patch file the headspace for preserving table address and return address, and the intermediate code of described patch file includes the instruction for preserving table address and the instruction for preserving return address.Described device responds in described second function Article 1 instruction and after jumping to described intermediate code, perform described intermediate code for preserving the instruction of table address and the instruction for preserving return address, the table address of described first function of current record and the return address of described first call instruction are saved in the headspace of described patch file.
Be understandable that, in the process performing described first function, in order to realize each call instruction in the first function, described equipment needs the table address recording described first function in internal memory.Particularly, described equipment finds the list structure of described first function according to the table address of described first function, searches the address of the allocating object of described first function in the list structure of described first function.Described equipment, according to the address of the allocating object found, finds the allocating object of described first function, realizes the execution of call instruction.Therefore, described equipment was at described first function of execution before jumping to described intermediate code, and what now record in described device memory is the table address of described first function.When performing the instruction of described intermediate code, the table address of its internal memory record is saved in described headspace by described equipment, then the table address preserved in described headspace is actually the table address of described first function.
It should be noted that, in the process of described first call instruction performing described first function, the return address that described equipment records in internal memory is the return address of described first call instruction, described like this equipment can described first call instruction call completely after return described first function again and continue execution subsequent instructions.Wherein, the return address of described first call instruction represents the address of next instruction of the first call instruction described in described first function.Described equipment was that the return address of now recording in described device memory is the return address of described first call instruction at execution described first call instruction before jumping to described intermediate code.When performing the instruction of described intermediate code, the return address of its internal memory record is saved in described headspace by described equipment, then the return address of preserving in described headspace is actually the return address of described first call instruction.
S204, in response to execution to the second call instruction in described intermediate code, jump to the 3rd function of described patch file, described 3rd function be used for described second function is upgraded.
In described intermediate code the instruction for preserving table address and for preserve return address instruction after comprise described second call instruction.Described second call instruction is for calling the 3rd function in described patch file.Visible, after described equipment performs described first call instruction of described first function, described 3rd function that what in fact described equipment performed is in described patch file instead of described second function, therefore just achieve described 3rd function and upgrade described second function.
Be understandable that, after jumping to described 3rd function, what described equipment performed is described 3rd function, and now, the table address recorded in described device memory is the table address of described 3rd function.And the table address of described first function originally recorded in described device memory will be dropped.Before jumping to described 3rd function, described equipment is at described second call instruction performing described intermediate code, now, the return address of recording in described device memory is the return address of described second call instruction, i.e. the address of next instruction of the second call instruction described in described intermediate code.And the return address of described first call instruction originally recorded in described device memory will be dropped.
S205, in response to the execution completing described 3rd function, according to the return address of described second call instruction, return described intermediate code.
Be understandable that, after described 3rd function is complete, described equipment, according to the return address of described second call instruction recorded in internal memory, returns next instruction of the second call instruction described in described intermediate code.
S206, instruction according to described intermediate code, recover the table address of described first function and the return address of described first call instruction from described headspace.
In the present embodiment, also comprise for recovery table address and the instruction for recovering return address after described second call instruction in described intermediate code.After turning back to described intermediate code from described 3rd function, the table address that described equipment can read described first function in response to the instruction for recovery table address from described headspace returns to record in internal memory, further, the return address that described equipment can read described first call instruction in response to the instruction for recovering return address from described headspace returns to record in internal memory.Wherein, return to the return address of described first call instruction of internal memory, after may be used for making complete described 3rd function of described equipment, finally turn back to next article of instruction of the first call instruction described in described first function.Return to the table address of described first function of internal memory, may be used for making described equipment can the allocating object of the first function described in normal call to perform after described 3rd function turns back to described first function the process of described first function.
S207, return address according to described first call instruction, return described first function.
After returning described first function, the table address of described first function due to what record in described device memory, described equipment can search the address of allocating object in the process of described first function of follow-up execution according to the list structure of described first function, thus each call instruction that described first function of correct execution is follow-up.
Furthermore, after returning described first function, break down or exception if described equipment performs in the process of described first function, then described equipment can determine that the loading of described patch file result in this fault or exception, now, described equipment can cancel the loading of described patch file.Particularly, the present embodiment such as can also comprise: return described first function in response to described, whether the execution of monitoring described first function breaks down; When the execution monitoring described first function is broken down, delete in described second function for jumping to the Article 1 instruction of described intermediate code.Be understandable that, the instruction for jumping to described intermediate code adds described second function to as Article 1 instruction when described patch file is loaded into software.After Article 1 instruction for jumping to described intermediate code in described second function is deleted, all instructions of described second function and the described intermediate code that no longer performs in described patch file and described 3rd function when described equipment jumps to described second function, will be performed.
Shown in Fig. 3 is the schematic flow sheet of equipment run time version instruction in the present embodiment.First function is the process function of software.Second function is the allocating object of described first function, is the original function needing in described software to upgrade.Patch file comprises headspace, intermediate code and the 3rd function.3rd function is the new function for upgrading described second function.Described first function comprises the first call instruction for calling described second function and instruction a, described instruction a are next instructions of described first call instruction, and namely the return address of described first call instruction is the address of described instruction a.Described second function comprises the instruction b for calling described intermediate code, and described instruction b is the Article 1 instruction of described second function.Described headspace comprises the space a for preserving table address and the space b for preserving return address.Described intermediate code comprise instruction c for preserving table address, for preserve return address instruction d, for call described 3rd function the second call instruction, for the instruction e of recovery table address, for recovering the instruction f of return address and the instruction h for returning described first function.Before described instruction c and described instruction d is positioned at described second call instruction, after described instruction e and described instruction f is positioned at described second call instruction, described instruction h is the last item instruction of described intermediate code.Described instruction e is next instruction of described second call instruction, the return address of described second call instruction is the address of described instruction e, or described instruction f is next instruction of described second call instruction, the return address of described second call instruction is the address of described instruction f.The last item instruction of described 3rd function is the instruction for returning described intermediate code.
According to the code execution flow journey shown in Fig. 3, perform in the process of described first function at equipment, when performing described first call instruction, described equipment jumps to described second function.When performing described instruction b, described equipment jumps to described intermediate code.When performing instruction c, the table address of described first function is saved in the space a in described headspace by described equipment, and the address of the described instruction a as return address is saved in the space b in described headspace.When performing described second call instruction, described equipment jumps to described 3rd function.When performing the last item instruction of described 3rd function, described equipment returns described intermediate code.When performing described instruction e, described equipment recovers the table address of described first function from the space a of described headspace.When performing described instruction f, described equipment recovers the address of described instruction a as return address from the space b of described headspace.When performing described instruction h, described equipment returns the instruction a in described first function.
In a specific embodiment, described equipment can adopt treatment scheme as shown in Figure 4 for the processing procedure of described patch file.In load phase, instruction for the intermediate code jumping to described patch file is added to the Article 1 instruction as described second function in described second function, and the address of described 3rd function is added in described intermediate code described second call instruction formed for calling described 3rd function.In the activation stage, described equipment runs described software, performs described first function, described second function, described intermediate code and described 3rd function according to instruction.If there is exception or fault in the operational process of described software, then cancel the loading of described patch file, the Article 1 instruction being used for calling described intermediate code in described second function is deleted.In the operation phase, described equipment normally runs described software, no longer cancels the loading of described patch file for the exception occurred in described software running process or fault.In the deletion stage, the Article 1 instruction being used for calling described intermediate code is deleted, and delete described patch file on said device in described second function.
In the technical scheme of the embodiment of the present invention, on the one hand, the table address of the first function lost when intermediate code calls the 3rd function, can recover from headspace executing before the 3rd function returns the first function, therefore, after returning the first function, the address of allocating object can be searched from the list structure of the first function according to the table address recovered in the process of execution first function, thus the allocating object avoided from the first function cannot be found when performing the first function again after the 3rd function returns the first function, the operation avoiding software is broken down, decrease the situation that interrupting appears in running software, on the other hand, although the return address of the first call instruction has been replaced by the return address of the second call instruction when intermediate code calls the 3rd function, but executing the return address can recovering the first call instruction before the 3rd function returns the first function from headspace, the first function can be returned according to the return address of the first call instruction recovered, thus avoid the execution that cannot return the first function continuation subsequent instructions after the 3rd function executes, the operation avoiding software is broken down, and decreases the situation that interrupting appears in running software, again on the one hand, headspace is reserved to preserve the table address of the first function and the return address of the first call instruction in patch file, the table address preserved and return address can not take stack frame structure, thus ensure that calling of the 3rd function has identical stack frame structure with calling of the second function, avoid stack frame structure and change the acquisition of information mistake caused, and then avoid the running software that acquisition of information mistake causes and interrupt.As can be seen here, by the technical scheme of the present embodiment, after patch file upgrades software, the many factors causing software interruption to be run are avoided, and therefore, the possibility that running software interrupts reduces greatly.
