Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, there are not many schemes for preempting a clipboard at present, and encryption and decryption are the related technologies closest to the preempting clipboard at present.
Some applications in the system need to process clipboard data, for example, an application needs to encrypt the clipboard, but due to the design problem of the application itself, the data cannot be successfully copied to the clipboard, but the data is temporarily stored in the disk, and since the storage has a cache function for storing small data, the design of the application will cause that the data is only put in the clipboard when the data queue temporarily stored in the disk reaches a certain amount, but the encrypted data of the encrypted clipboard at each time is different from the requirements of the client itself. The client needs to feel that the data copied to the clipboard each time is encrypted, but with the design, the client actually feels that the clipboard is encrypted only once after a plurality of clipboard operations, and in addition, the display of an interface is difficult to perform, and the statistics are troublesome. Since the design of the application is performed by a specialized person, it is very difficult to implement the storage of the data copied each time into the clipboard by modifying the design of the application.
In the Windows environment, clipboard technology has developed to be very stable and mature. Windows divides the clipboard into a logical address space, and the processing of clipboard data can be said to be very easy.
For the domestic operating system based on the secondary development of Linux, the development of the kernel of the system is very little, the design of the system is less, the clipboard is used as a main system module, the research is less due to the reasons, the technology is immature, and the compatibility of the product made by the clipboard is poor.
Most clipboard data processing programs of the prior art perform a large number of operations, which results in low efficiency. The low efficiency can cause a series of bad chain reactions and poor customer experience
In summary, the existing clipboard technology based on the domestic operating system has the following disadvantages:
1. typically clipboard data for a particular application.
2. Compatibility with the system is not particularly good.
3. The clipboard of the Linux system is of a c/s architecture, the permissions of the clients designed by the clipboard are parallel, the clipboard business logic and the clients are parallel, and therefore other clients are difficult to control, and even if the other clients can be controlled, the system stability and the system performance are also reduced.
4. The existing clipboard technology generally calculates and processes too much data, occupies more machine resources and has low reflection speed.
In view of the foregoing problems, the present invention provides a data processing method, system, electronic device, and medium, where the improved clipboard-specific data processing method has the beneficial effects of being capable of adapting to various application scenarios, realizing flexible application in combination with other functions, having strong compatibility, ensuring successful clipboard data preemption, efficiently preempting clipboard data, and minimizing resource usage. The invention will now be explained and illustrated in detail by means of specific examples.
Fig. 1 and fig. 2 show flowcharts of a data processing method provided by an embodiment of the present invention. As shown in fig. 1 and fig. 2, a data processing method provided in an embodiment of the present invention includes the following steps:
step 110: monitoring a clipboard event related to a clipboard;
step 120: if a clipboard event is monitored, clipboard data to be transferred to a clipboard are intercepted; and
step 130: and transmitting the intercepted clipboard data to a clipboard server.
In this example, clipboard events related to the clipboard, such as the copying of data onto the clipboard to be performed by the processes of the respective applications, are monitored by the monitoring module.
If a clipboard event is monitored, before each client transfers data to a clipboard through the clipboard event, clipboard data to be transferred to the clipboard is intercepted from a corresponding process, and specifically, the clipboard data to be transferred to the clipboard is intercepted through an interface of the corresponding process.
After the slave process intercepts clipboard data to be transferred to the clipboard, the intercepted clipboard data is set to the clipboard, i.e., the clipboard server.
For an application process that does not clip data, such an application process usually temporarily puts data into a disk, and when pasting the data to another application program, the process of such a type may fail to paste the data because the data is empty when pasting the data of the board, i.e., the process fails to paste the data. The invention perfectly solves the problem, copies the data and puts the data into the temporary disk file, and the invention preempts the data and puts the data into the clipboard again by preempting the clipboard data program.
In this example, the system clipboard data is monitored first, and then, the system clipboard is reset without any data processing, so as to achieve the purpose of preempting data.
In the embodiment, the clipboard data are preempted timely and efficiently by monitoring the clipboard events related to the clipboard, and the preempted clipboard data are set to the clipboard, so that the data corresponding to each copying operation executed by each application can be successfully copied to the clipboard server, and the problem of poor user experience caused by the fact that some applications do not copy the data to the clipboard successfully or timely but temporarily store the temporary data to a disk is avoided.

In the embodiment, the actions of transferring the data to the clipboard, which are executed by all the processes, are monitored, so that the actions of copying are quickly identified, the data are quickly acquired, and the data are efficiently and reliably set to the clipboard.
Based on any of the embodiments described above, in a data processing method provided by another embodiment of the present invention,
listening for actions performed by all processes in relation to the clipboard includes:
intercepting action messages of all processes related to the clipboard.
In one example, a clipboard event related to a clipboard is listened to by intercepting (capturing) all processes' action messages related to the clipboard, and informing a monitoring module (a client for obtaining clipboard data) that a clipboard change has occurred.
In the above embodiments, by intercepting (capturing) all processes' action messages related to the clipboard to listen to clipboard events related to the clipboard, efficient and flexible data location and retrieval can be achieved.
Based on any of the embodiments described above, in a data processing method provided by another embodiment of the present invention,
intercepting clipboard data to be transferred to a clipboard comprises:
clipboard data is intercepted by a client for obtaining clipboard data.
In one example, clipboard data is intercepted by a client for obtaining clipboard data. The Linux clipboard server is a server of all clients, so when monitoring whether the clipboard data changes, a message notification is registered in the server, the server is made to tell the client, so that the purpose of monitoring is achieved, and the clipboard data is acquired by calling the clipboard data by the client.
In the above embodiment, the clipboard preemption program realizes preemption of the clipboard data by the client and the clipboard server for obtaining the clipboard data, and ensures the purpose of setting the clipboard data to the clipboard. And meanwhile, the data is taken by using a data transfer mode optimized by the system, so that the efficiency is highest.
Based on any of the embodiments described above, in a data processing method provided by another embodiment of the present invention,
the listening for clipboard events related to a clipboard comprises:
the clipboard server receives the action message related to the clipboard, and after receiving the message, notifies the client for obtaining the clipboard data, wherein after receiving the notification, the client intercepts the clipboard data to be transferred to the clipboard.
The client obtains clipboard data from the process that performed the copy.
In the above embodiment, the clipboard preemption program realizes preemption of the clipboard data and ensures the purpose of setting the clipboard data to the clipboard. And meanwhile, the data is taken by using a data transfer mode optimized by the system, so that the efficiency is highest.
Based on any of the embodiments described above, in a data processing method provided by another embodiment of the present invention,
transmitting the intercepted clipboard data to a clipboard server comprises:
and judging whether the clipboard data is the clipboard data needing to be monitored, and if so, transmitting the intercepted clipboard data to a clipboard server.
The client is a client specially used for intercepting the clipboard data, the specific clipboard data is monitored by checking the clipboard message to be concerned, and some clipboard data do not need to be monitored by the client, so that the operation of setting the clipboard data to the clipboard does not need to be executed.
In the embodiment, whether the clipboard data belongs to the clipboard data which needs to be monitored by the client is judged, so that the subsequent operation of setting the clipboard data which does not need to be monitored by the client to the clipboard is avoided, resources are saved, and the efficiency is improved.
Based on any of the embodiments described above, in a data processing method provided by another embodiment of the present invention,

and adding an identifier to the clipboard data.
When the clipboard data is set to the clipboard, the clipboard data is added with an identifier, which may be, in one example, a code added to the clipboard data that can embody the source and destination of the clipboard data.
In the above embodiment, by adding the identifier to the clipboard data, convenience is provided for a subsequent client to perform a specific operation.
Based on any of the embodiments described above, in a data processing method provided by another embodiment of the present invention,

In the above embodiment, the client in the operating system may perform the relevant operation by reading the identifier, and such a data processing method is more efficient and saves resources.
Based on any of the embodiments described above, in a data processing method provided by another embodiment of the present invention,
the data processing method is used in a Linux operating system.
Specifically, the data processing method is used in a domestic Linux-based secondary development operating system. The clipboard preemption program of the invention is designed for a domestic operating system based on Linux secondary development.
The domestic operating system developed based on Linux twice has the following problems:
the operating system which is mainly patterned by Microsoft is favored in China almost, even an IT development enterprise of Linux generally develops applications, the development of a kernel and the like is not needed because of open sources, in short, the system is designed less, a clipboard is used as a main system module, the research of the reasons is less, the technology is immature, and the compatibility of products manufactured by the clipboard is poor.
At present, in a domestic operating system, a clipboard technology is mainly used for an encryption and decryption technology for a certain application, and has limitations. The reason is that the development of the domestic operating system under the open source Linux system is completely because the domestic operating system has just started for security in recent years, so the support of the domestic operating system on the clipboard generally supports a single application or depends on more environments, and the development of the application is based on the system and under the condition that the system is not stable, so the application has certain dependence on the system, and the clipboard technology and certain application are closely related.
The clipboard in the Linux system is of a c/s architecture, and the permissions of the clients designed by the clipboard are parallel. The clipboard business logic itself is also a parallel authority with each client. It is not very good to implement the control of the other clients themselves, i.e. it is not very reliable.
Due to the above clipboard related problems of the Linux operating system, the clipboard preemption program is designed to solve the above clipboard related problems of the Linux operating system. Meanwhile, in order to ensure that resources are used in a minimized mode, the clipboard preemption program of the invention takes the design characteristics of a Linux system as a trigger point, and develops the most resource-saving functional application.
In addition, the invention considers that the clipboard has no established data address in the Linux system, so the clipboard data can not be encrypted and decrypted like the Windows system under the Linux. Therefore, the data is taken from the Server of the clipboard, and the clipboard data is updated after the data is processed, namely, the data is processed according to the business logic.
In the above embodiment, the clipboard preemption program of the present invention realizes preemption of the clipboard data by creating the client and the clipboard server for acquiring the clipboard data, and ensures the purpose of setting the clipboard data to the clipboard, thereby solving the above technical problems in the current domestic operating system.
Adaptation for various application scenarios and flexible application in conjunction with other functionality
The client needs to preempt the clipboard to provide preempted data for the client, but sometimes needs to do some data processing during preemption and sometimes does not do so because of the requirement when the business is huge, and the program has the superiority of design, namely, the clipboard preempts each operation, so that no matter what kind of application or environment, the program for preemption can always process the data or keep the original data as required, and the application is very flexible to meet different business requirements. In addition, even if some applications store the copied data in the temporary disk directory every time, the preemption clipboard can preempt the data every time and help to place the data in the clipboard, so that the problem that a client feels that the data copied to the clipboard every time cannot be encrypted because the storage of small data has a cache function, and the client feels that the clipboard is encrypted only after a plurality of clipboard operations.
Regarding compatibility
The clipboard preemption program of the invention deeply researches the working principle of the bottom layer of the clipboard, and the compatibility is suitable for the matching problem of almost various Linux distribution versions and different versions of the same distribution version. The clipboard architecture is summarized below each Linux version, and the clipboard architecture of Linux is found to be a model of c/s architecture, so that the c/s architecture is not changed even if the Linux version is upgraded, and the c/s architecture is upgraded by optimizing certain details and certain functions in the c/s architecture. The invention grasps the details of the clipboard architecture and the development rule of the Linux system, and does a great deal of work for compatibility at a certain height, thereby solving the problem of great difference of single release version of the Linux system and the problem of great change of numerous Linux release versions.
Concerning high efficiency
The high efficiency means that under the condition of ensuring that clipboard data is occupied, the CPU is not consumed too much.
The simpler the design efficiency is higher, the better the large-scale system development can be adapted to. In order to ensure the minimum use of resources, the clipboard preemption program develops the most resource-saving functional application by taking the design characteristics of the Linux system as a trigger point.
Under Linux, communication is carried out between application processes, between a kernel and application programs and between the application programs through a socket. Preempting the clipboard data program first analyzes the clipboard data interaction between the kernel system and the application program, and takes the data in a data transfer manner optimized by the system. The invention does not make a driver to develop a clipboard program, and mainly considers the efficiency and the compatibility of the application.
The software of the invention firstly monitors the system clipboard data, hardly processes any data and then resets the clipboard data to the system clipboard, thus achieving the purpose of preempting the data.
Ensuring successful preemption of clipboard data
The invention adopts a simpler and very guaranteed mode to realize that: every time the clipboard data changes, the program sets the data to the clipboard once, ensuring that the last clipboard data is always preempted to obtain the clipboard data. The invention adopts a flexible mechanism to ensure that the clipboard data changes every time, namely, a certain process puts the data on the clipboard, and the clipboard preemption program inevitably takes the data and sets the data in the clipboard. Therefore, the final data of the clipboard is the data which is processed by preempting the clipboard, so that the design of the invention can be ensured to preempt the clipboard data.
The contribution of the invention in the technical aspect is at least as follows: technical support is provided for development of subsequent clipboard technology, and when a clipboard encryption and decryption developer finds that certain application is encrypted, certain data of the application is not successfully copied to a clipboard, the technology can be used as a technical basis to easily develop business functions related to clipboard encryption and decryption.
The invention makes at least the following contributions in an economic aspect: the invention has high efficiency of processing data, greatly reduces the dependence degree on higher hardware for a large-scale system or a huge data statistical module, and saves the hardware cost. The response speed to the client request is improved, and higher service benefits are generated.
The data processing method provided by the invention is particularly suitable for a domestic Linux-based secondary development operating system. The clipboard preemption program in the data processing method of the invention monitors clipboard events through the monitoring module aiming at the clipboard, and intercepts the clipboard data through the client used for acquiring the clipboard data, thereby realizing the preemption of the clipboard data and realizing the purpose of ensuring the successful setting of the clipboard data to the clipboard.
