Abstract
Description
Technical Field
[0001] The invention belongs to the field of software development, and in particular relates to a binary document modification method and system. Background Art
[0002] In the field of computer application software, especially stand-alone software or client software running in C / S architecture, private format files are usually used to save the content results of production and processing and the process information required for reprocessing. These private format files generally use two formats, one is based on formatted text, such as XML, Json, etc., and the other is a structured binary format.
[0003] Storage files defined based on formatted text can randomly access specific items, are easy to expand, can be viewed with the help of general tools such as XML and Jason, are easy to parse and modify, and can be easily accessed, edited and modified by third-party software, which is equivalent to an open format. However, the file size is usually large, and encoding and decoding are required to store binary data. The access code is relatively complex, and there is a big difference with the memory structure. The reading and storage speed is slow, and the confidentiality is poor.
[0004] The opposite is true for files stored in a structured binary format. Binary files are usually generated by software in a serialized manner. They are small in size, highly consistent with the data and memory structure, fast to read, and highly confidential. However, they are difficult to parse, and third-party software cannot access them unless they understand all the structural details. It is very difficult to modify and add data.
[0005] For stand-alone software or C / S architecture systems with file exchange requirements, there are often situations where multiple machines collaborate. Files saved after processing on one machine are often transferred to other machines to be opened again for further processing, or files are directly copied and used. The copied files need to change some of their contents according to the new application environment before they can be used in the new environment. Since third parties cannot know the details of the binary file structure, they cannot modify it. Even if they know all the details, imitating the exact same serialization structure will result in a large program and difficult debugging. It is generally considered to be unmodifiable by external programs, which makes collaborative processing of binary files very inconvenient.
[0006] Therefore, it is necessary to propose a binary file modification method so that the file content can be modified while ensuring the confidentiality of the file when multiple machines collaborate to process it. Summary of the invention
[0007] In view of this, an embodiment of the present invention provides a binary document modification method and system, which are used to solve the problem that binary files cannot be modified when multiple machines collaborate to process.

DETAILED DESCRIPTION
[0017] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] It should be understood that the term "including" and other similar expressions in the specification or claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions, such as a process, method, system, or device including a series of steps or units is not limited to the listed steps or units. In addition, "first" and "second" are used to distinguish different objects, not to describe a specific order.
[0019] See also Figure 1 , a flowchart of a binary document modification method provided by an embodiment of the present invention includes: S101, when it is detected that the user saves the result file produced by the software, a serialization function is called to convert the software memory structure data corresponding to the result file into a binary data stream, and store it in a main file; The result file is a file generated when the user produces or processes it through application software, such as book, magazine, and newspaper layout files produced by the user through typesetting software, slide files produced by office software, and design drawings produced by CAD software. The result file is generally generated by the user's current application and exists in a fixed format in the internal cache space of the software, that is, the software memory structure data. When the user chooses to save, it is usually stored in the storage space outside the program body in the form of a binary file or formatted text.
[0020] The serialization function is used to convert a complex computer memory data structure into a linear byte stream or character stream while retaining the integrity of the data structure. The serialization function can write the data in the application software memory structure into the main file in byte order for long-term storage. The corresponding read function uses the deserialization method, and when reading, the file data stream is read strictly in the order of writing and directly filled into the memory structure.
[0021] S102, calling a first access function to search for a predetermined data item in the software memory structure data, and storing an identifier and an attribute value corresponding to the predetermined data item in an auxiliary file; The first access function can access the software memory structure data corresponding to the result file, and store the pre-set data items and their identifiers and attribute values in the auxiliary file. The predetermined data items are generally related to the file running environment, such as the external objects referenced by the file (such as the storage path of the image), the external identifier of the object, and the file attributes, type and other data items. The predetermined data items are data items related to the result file environment parameters, that is, when the environment parameters change, the attribute values in the predetermined data also need to change.
[0022] The identifier of the predetermined data item, the current attribute value, etc. are stored in the auxiliary file through the first access function. The content and format of the predetermined data item can be defined by the developer.
[0023] The auxiliary file is a storage file defined by formatted text. The auxiliary file can be in INI, XML, json or other file formats that are easy to view, edit and append.
[0024] It can be understood that the binary main file and the formatted auxiliary file constitute an external storage file pair, which is automatically generated by the software when the software saves the processed content externally. Generally speaking, there is no strict order restriction on the generation of the main file and the auxiliary file, but in order to facilitate the judgment of the validity of the auxiliary file, the auxiliary file can be generated first, and then the main file, so that the generation time of the main file is slightly later than that of the auxiliary file.
[0025] In this embodiment, the auxiliary file only stores a small amount of variable data items in the result file and supports random position reading and writing of data, which can make the modification of binary files simple and feasible, and has fast reading and writing speed and small data volume.
[0026] S103, when it is detected that the environment parameter of the result file has changed, calling the second access function to open the auxiliary file, searching for the data item and attribute value corresponding to the environment parameter according to the identifier, and modifying the attribute value corresponding to the environment parameter; Among them, the first access function is used to find the identifier and attribute value corresponding to the predetermined data item in the internal structure data and store them, and the second access function is used to find the corresponding data item and attribute value in the auxiliary file according to the identifier and assign the attribute value.
[0027] When the result file is copied or transferred to other environments, the environment parameters of the file will change. For example, when the result file is copied to another machine, the operating system, hard disk storage directory structure, application version, etc. of the machine will be different from the original application production environment, and the environment parameters of the file need to be modified.
[0028] The corresponding data item and attribute value in the auxiliary file are searched by the identifier through the second access function, and the attribute value of the data item is modified.
[0029] S104: When it is detected that the user has opened the result file, the main file and the auxiliary file are read respectively. Specifically, when it is detected that a user opens the result file, the deserialization function is called to read the binary data stream of the main file and fill it into the software memory structure, and the third access function is called to read the identifier and attribute value in the auxiliary file, and the data item and attribute value are searched according to the identifier, and the attribute value of the corresponding data item in the software memory structure is overwritten.
[0030] When the application needs to open the result file, it can read the main file and the auxiliary file from the outside respectively, and fill the binary data stream and data item attribute value information read from the outside into the program's memory structure.
[0031] It can be understood that the first access function and the third access function are called by the production software and are used for storing and reading the result file respectively, and the second access function can be called by the storage management software to find and modify the attribute value of the data item in the auxiliary file.
[0032] Optionally, before calling the third access function to read the identifier and the attribute value in the auxiliary file, the step further includes: Determine whether the auxiliary file exists. If so, obtain the last modification time of the auxiliary file. When the last modification time of the auxiliary file is earlier than the generation time of the main file, mark the auxiliary file as unreadable.
[0033] In this embodiment, when the application software stores files externally, it will generate a file group of a main file and an auxiliary file. Since the main file is a serialized binary file and there are only a few modifiable data items in the auxiliary file, it will basically not affect the speed of storing files and storage space. When the software opens the stored file again, it reads the binary main file and the auxiliary file respectively, and overwrites the attribute value of the corresponding data item in the memory structure according to the content in the auxiliary file. Since there are only a few modifiable data items in the auxiliary file, it will basically not affect the speed of reading files.
[0034] By combining binary format files with formatted text files, a binary format main file and a formatted text auxiliary file are generated to form a storage file pair, which fully utilizes the advantages of two file format accesses, can read and write at high speed, has a small file size, and can support external software to modify binary files. Only for a small number of variable data items, auxiliary formatted text access functions are written, which does not affect the original file storage speed, and allows external programs to modify variable data items. The actual use cost is low and easy to implement.
[0035] It should be understood that the serial numbers of the steps in the above embodiments do not imply a sequence of execution, and the execution sequence of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0037] The data modification module 220 is used to call the second access function to open the auxiliary file when it detects that the environment parameter of the result file has changed, find the data item and attribute value corresponding to the environment parameter according to the identifier, and modify the attribute value corresponding to the environment parameter; The data reading module 230 is used to read the main file and the auxiliary file respectively when it is detected that the user opens the result file.
[0038] Specifically, when it is detected that a user opens the result file, the deserialization function is called to read the binary data stream of the main file and fill it into the software memory structure, and the third access function is called to read the identifier and attribute value in the auxiliary file, and the data item and attribute value are searched according to the identifier, and the attribute value of the corresponding data item in the software memory structure is overwritten.
[0039] Wherein, before calling the third access function to read the identifier and the attribute value in the auxiliary file, the method further includes: Determine whether the auxiliary file exists. If so, obtain the last modification time of the auxiliary file. When the auxiliary file's last modification time is earlier than the generation time of the main file, the auxiliary file is marked as unreadable.
