Protection scope within.
The present invention provides a kind of Dylib reference delet method, device, system and computer readable storage medium, it is intended to solve
The problem of data resource of useless Dylib citation impact Macho file certainly existing in the prior art.
Referring to Fig.1, Fig. 1 is the flow diagram of one embodiment of the invention.
In one embodiment, this method comprises:
S101 determines Dylib reference to be deleted.
Specifically, it is first determined Dylib reference to be deleted, that is, the Dylib file to be deleted of determination is in Macho text
Reference information in part.
S102 is determined in Macho file for saving the target LoadCommand of the Dylib reference to be deleted.
It should be noted that Macho file has specific composition format, wherein the part for quoting Dylib is located at
The region LoadCommands, wherein region refers to the byte in a segment limit, and the region LoadCommands indicates that segment limit
Byte is all for storing the relevant information of LoadCommands.The region LoadCommands is by multiple LoadCommand
Composition, a LoadCommand saves the reference information of a Dylib, so additions and deletions Dylib is exactly to pass through additions and deletions
LoadCommand in the region LoadCommands is realized.
Therefore, it is determined in this programme in Macho file for saving the target of Dylib reference to be deleted
LoadCommand。
All bytes of the target LoadCommand are set to redundancy bytes by S103, described to be deleted to complete
The deletion of Dylib reference；Wherein the redundancy bytes are in the Macho file for being replicated into new LoadCommand's
Byte.
It should be noted that having a limitation when modifying the byte in the region LoadCommands, cannot exactly change
The region totality byte quantity.This is also that the reason of can not deleting Dylib reference directly in Macho file, Dylib is quoted
It directly deletes, then the byte number that will lead in LoadCommands tails off, so that the program can not be implemented.
And the requirement being aligned by memory, the region LoadCommands can have some redundancy bytes in its tail portion, these redundancies
Byte can be replicated into new LoadCommand, and increasing LoadCommand operation can be by making carbon copies these redundancy bytes
It completes, one LoadCommand information of every addition will occupy a part of redundancy bytes, exhaust until by redundancy bytes.
Therefore, in the present solution, all bytes of target LoadCommand are all set to redundancy bytes, thus corresponding
The byte of the LoadCommand can all be replicated into new LoadCommand, although to be not carried out actual deletion
Operation, still, since the byte of target LoadCommand has all been set to redundancy bytes, the reference effect of script is not also deposited
To realize the effect for deleting corresponding logic program segment；And the corresponding data of target LoadCommand are provided
Source is available, for being replicated new LoadCommand, to solve the problems, such as the waste of data resource in Macho file.
In a specific embodiment, redundancy bytes are the byte that all positions are 0.

The byte of target LoadCommand is set to redundancy bytes by target LoadCommand, although to be not carried out actual delete
Except operation, still, since the byte of target LoadCommand has all been set to redundancy bytes, the reference of script is acted on also not
In the presence of to realize the effect for deleting corresponding logic program segment；And by the corresponding data of target LoadCommand
Resource is available, for being replicated new LoadCommand, to solve the problems, such as the waste of data resource in Macho file.
On the basis of previous embodiment, the present embodiment is further detailed and optimizes to technical solution.
It is specific as follows:
Before previous embodiment step S103, the method also includes:
All bytes of the target LoadCommand are moved to all LoadCommand in current Macho file
Tail portion.
It should be noted that after since target LoadCommand is set to redundancy bytes, corresponding redundancy bytes
It is replicated into new LoadCommand again, and when the no longer tail portion in the region LoadCommands target LoadCommand,
Since the back target LoadCommand also has other LoadCommand, so corresponding superfluous in target LoadCommand
The byte number that remaining byte goes out the LoadCommand made carbon copies can only be less than or be equal to target LoadCommand, will receive byte number
Limitation.And the tail portion in the region LoadCommands has pre-added redundancy bytes, it, can be in order to reduce the limitation of byte number
Target LoadCommand is first moved to the tail portion LoadCommands, is then set to redundancy bytes again, is being made carbon copies newly in this way
When LoadCommand, byte limitation is no longer just the byte number of target LoadCommand, but the word of all redundancy bytes
Joint number is more convenient the management of subsequent newly-increased LoadCommand and the management of redundancy word joint number.
On the basis of previous embodiment, the present embodiment is further detailed and optimizes to technical solution.
It is specific as follows:
After previous embodiment step S103, the method also includes:
It makes carbon copies the target LoadCommand and adds new Dylib reference.
