Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, 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 the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The schematic flow sheet of the hot patch disposal route that as shown in Figure 1, the embodiment of the present invention one provides.As shown in Figure 1, the executive agent of the described method of the present embodiment can be hot patch treating apparatus.Wherein, described hot patch treating apparatus can be specially the client application software being arranged on client device.User is after hot patch treating apparatus described in local installation, in local computer, stored the patch information for carrying out hot patch processing, or local computer can carry out alternately to obtain corresponding patch information in real time by internet and server end.As shown in Figure 1, the hot patch disposal route described in the present embodiment comprises:
Whether step 101, monitoring have new program module to load.
Concrete, this step can adopt the message processing facility of existing Windows, and HOOK mechanism realizes.Wherein, the message processing facility of Windows for can be in application program the variety of event message of supervisory system, the function that articulates various hooks (also or claim readjustment or instead adjust English Hook) function is provided.HOOK function is used for monitoring the transmittance process of message, and before it arrives object process or object module, by its intercepting and capturing.
If step 102 has, obtain patch information corresponding to described program module.
Concrete, described patch information can be stored in default hot patch application configuration file.For example, in described hot patch application configuration file, include characteristic information and the corresponding patch information of at least one program module.Wherein, the characteristic information of described program module can comprise: the filename of program module, the file path of program module, one or any number of combinations in the version information field (VersionInfo) of the timestamp field (TimeStamp) of program module, the checksum field (CheckSum) of program module and program module.
Corresponding, this step can be adopted with the following method and be realized:
First, extract the characteristic information of described program module.
Then,, according to default characteristic information and the corresponding relation of patch information, obtain the patch information that described characteristic information is corresponding.
Here you need to add is that: described hot patch application configuration file is loaded and resolved by service processes, and preserve with Memory Mapping File and its (File Mapping) object of sharing, follow-up each process is only responsible for reading File Mapping, and need not reload and resolve described hot patch application configuration file.In addition, also it should be noted that: described hot patch application configuration file also comprises check information (as cyclic redundancy check (CRC) information and version information etc.) herein.Therefore patch information corresponding to described program module that, this step gets also should meet by the integrity checking based on CRC calculating and the security inspection of version information.
Concrete, described patch information can comprise: patch function address and by patch function address.Corresponding this step 103 specifically can be adopted with the following method and be realized:
First, before described program module operation, according to described patch function address and described by patch function address, structure jump instruction.
For example, described patch function address is 0x1600000, is 0x300080 by patch function address, adopts jump instruction operational character JMP TO, and the jump instruction that structure obtains is JMP0x12fff7b.
Then, will described in described program module, be replaced with described jump instruction by the instruction at patch function address place.
The instruction by patch function address 0x300080 place in described program module is replaced with to the jump instruction JMP0x12fff7b that previous step obtains, completed the replacement of instruction.Like this in described program module implementation, in the time carrying out described 0x300080 address place, will jump to corresponding patch function by described jump instruction JMP0x12fff7b, carry out this patch function, so just realized in the operation of interrupt routine not and just can carry out the object of reparation in real time to program.
Further, described in the method described in the present embodiment, after step 103, also comprise the steps:
Carry out described program module, and in the process of implementation in the time calling described in described program module by the instruction at patch function address place, jump to the patch function at described patch function address place according to described jump instruction, carry out described patch function.
Here you need to add is that: described patch function is read in patch file buffer zone in advance.Described patch function address can be the address of described patch file in described buffer zone.
The technical scheme that the present embodiment provides is by the load condition of monitoring new procedures module, with after loading in program module, obtain the patch information of described program module, then before program module operation, according to described patch information, described program module is carried out to hot patch processing, so just can be in the situation that interrupt routine move, system program or application program are repaired or upgraded, improved the efficiency of patch processing.
Further, as shown in Figure 2, the method described in above-described embodiment, except comprising above steps, also comprises the steps:
