Detailed Description
The technical scheme of the application is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart illustrating a file attribution information recording method according to an embodiment of the present application, where the method may be executed by a file attribution information recording device, where the device may be implemented by software and/or hardware, and may be generally integrated in a terminal. As shown in fig. 1, the method includes:
For example, the terminal in the embodiment of the present application may include a device such as a mobile phone, a tablet computer, and a notebook computer, which is installed with an operating system. The type of the operating system is not limited in the embodiment of the present application, and may be, for example, an Android operating system, a Windows operating system, an apple operating system (ios), and the like.
In the terminal, all installed application programs have the authority of operating the terminal to store, and more files including junk files can be generated after long-term accumulation. When managing or otherwise operating a file in a terminal, it is usually necessary to perform a targeted process according to the attribution of the file, i.e. to which application the file belongs. In the related art, the attribution condition of the file is generally determined according to the storage path of the file, however, the files of all the application programs are not stored under the corresponding storage paths of the application programs, and therefore, the determination mode is not accurate. In the embodiment of the application, the attribution information of the file is determined at the beginning of file creation starting from the source of the file, and the attribution information of the file can be accurately obtained.
For example, when creating a file, an application program generally creates the file in a terminal storage through an application layer, and the final implementation is to create the file in a file system of a system bottom layer (such as a kerel layer). The terminal storage makes multiple use of a virtual file system, such as the SDcardFS file system. The virtual file system stored in the terminal is generally used for controlling file access permission, the operation and the parameters can be converted into the operation and the parameters of the bottom layer file system, one file object is correspondingly created in the bottom layer file system after the virtual file system layer creates the file object, the file object created in the virtual file system layer is only stored in the memory and disappears after power failure, and data in the real file is stored in the bottom layer file system. In the embodiment of the application, the file creating operation of the application program can be monitored in the corresponding virtual file system layer stored in the terminal. The first file may be any type of file created by any application, and the present application is not limited thereto.
For example, when creating a file, an application program is generally initiated by an application process in the application program, and the application program to which the process identifier belongs may be determined according to a process identifier (pid) of the application process initiating the creation operation, so as to obtain a target application program. The pid is the identity of the process, the application program may contain a plurality of processes, the pid of each process is unique, and the pid can be used to identify the identity of the application program.
Optionally, the application identifier (uid) of the application program initiating the creation operation may also be obtained directly by using an existing interface, such as current _ uid, to determine the target application program. The uid is an identification of the application, and the uid of each application is unique, and the pid can be used to identify the identity of the application.
And 103, recording the identity information of the target application program as the attribution information of the first file to a bottom file system, wherein the bottom file system is realized based on a physical storage medium.
As described above, the underlying file system is used for actually storing file data and needs to be implemented based on a physical storage medium, and the data stored therein is not lost after power failure. Therefore, in the embodiment of the application, after the target application program is determined, the identity information of the target application program is recorded in the underlying file system as the attribution information of the file, so that persistent storage of the attribution information of the file is realized, and the attribution information of the file is not lost when the terminal is restarted.
For example, the identity information may include an application name, an application code, and an uid of an application, and the embodiment of the present application is not limited thereto.
The file attribution information recording method provided by the embodiment of the application determines a target application program initiating a creation operation when the creation operation of a first file is monitored, and records identity information of the target application program as attribution information of the first file to a bottom file system, wherein the bottom file system is realized based on a physical storage medium. By adopting the technical scheme, the identity information of the application program for creating the file can be acquired when the file is created, and the identity information is stored into the bottom file system as the file attribution information, and the bottom file system is realized based on the physical storage medium, so that the owner of the file can be accurately and persistently recorded, and the file can be conveniently managed in a targeted manner.
In some embodiments, the underlying File System comprises a Fourth generation Extended File System (EXT 4) or a Flash Friendly File System (F2 FS). EXT4 is a log file system under the Linux operating system, and the android system is based on the Linux kernel, so EXT4 can be used as the underlying file system. F2FS is a new open source flash (flash) file system specifically designed for NAND-based storage devices, also supporting the Linux operating system. The EXT4 or F2FS may reside in an Embedded multimedia memory Card (EMMC or EMMC). The EMMC generally adopts a unified MMC standard interface, encapsulates the nonvolatile flash memory and the MMC controller in one chip, and is a local storage solution generally adopted by a terminal.
In some embodiments, the monitoring of the creation of the first file comprises: monitoring a creating request of a first file initiated by an application program through calling a file creating interface of an application layer through a preset function added in a preset virtual file system; and when the creation request is monitored, determining that the creation operation of the first file is monitored. The method has the advantages that the file creation request can be monitored timely and accurately, and the file attribution information can be recorded quickly. When the application program creates a file, a file creation (file creation) interface of the application layer is called to create the file in the terminal storage, for example, when a user uses a camera application to take a picture, the camera application calls the file creation interface of the application layer to create a picture related file in the terminal storage. In the embodiment of the present application, a preset function, such as an SDcardFS file system, may be added to a preset virtual file system, such as an SDcardFS-SDcardFS _ create function, to implement a creation request for monitoring a file, and further implement a creation action for automatically identifying a file.
In some embodiments, the recording the identity information of the target application as attribution information of the first file to an underlying file system includes: acquiring identity information of the target application program to obtain attribution information of the first file; and recording the attribution information of the first file into the extended attribute of the underlying file system. The extended attribute (xattr) of the bottom file system is the characteristic of the Linux bottom file system, is used for recording and storing data customized by a user, has high access speed and small memory space occupation, and can quickly realize an interface provided by kernel. Illustratively, the identity information may be the uid of the application, which may be stored in xattr in the form of a string.
In some embodiments, after recording the identity information of the target application as attribution information of the first file to an underlying file system, the method further comprises: when an acquisition request of an application layer for attribution information of a first file is monitored, acquiring attribution information of the first file from the bottom layer file system through a preset interface realized in the preset virtual file system, and returning the attribution information to the application layer. The advantage of this arrangement is that the application layer can be supported to obtain the recorded file attribution information and perform subsequent operations according to the attribution information. For example, the implementation and definition of the preset interface may be used in an SDcardFS File System of kernel to obtain the uid character string recorded in the extension attribute xattr of the underlying File System, and then provide the uid character string to the upper layer application through a Virtual File System (VFS) mechanism of the kernel standard. Optionally, when a preset application program in the terminal, such as a housekeeping application program, needs to obtain the attribution information of the file, the application layer may initiate an attribution information obtaining request for the first file, and obtain the attribution information of the first file from the underlying file system through a preset interface in the SDcardFS file system.
In some embodiments, after obtaining attribution information of the first file from the underlying file system and returning the attribution information to the application layer, the method further includes: and determining the management strategy of the first file according to the attribution information. After the attribution information of the file is obtained, the file can be managed in a targeted manner according to the application program to which the file belongs, such as operations of compressing, deleting, format conversion, encryption, hiding and the like on the file, or a display mode of the file (for example, different icons are displayed in a file manager according to the application program to which the file belongs), a storage path, an operation authority and the like are controlled.
In some embodiments, the method and the device can also be used for tracking malicious applications, for example, security applications in the terminal, such as antivirus applications, when an abnormal file (such as a virus file) is detected, the application to which the abnormal file belongs may be determined by obtaining attribution information of the abnormal file, and then corresponding processing is performed on the application, such as risk prompt, operation authority control, uninstallation, and the like. By way of example, the embodiment of the present application may further include: detecting an abnormal file through a security application program, when a first abnormal file is detected, initiating an attribution information acquisition request aiming at the first abnormal file through an application layer, acquiring attribution information of the first abnormal file from a bottom layer file system through a preset interface realized in a preset virtual file system, and returning the attribution information to the security application program; and determining a corresponding abnormal application program according to the received attribution information through the security application program, and carrying out corresponding processing on the abnormal application program.
In some embodiments, the determining the management policy of the first file according to the attribution information includes: determining whether the corresponding target application program is in an uninstalled state or not according to the attribution information; and if so, clearing the first file. The method has the advantages that the residual files of the uninstalled application programs can be accurately positioned, so that the residual files are accurately cleared, and the storage space of the terminal is saved on the premise of avoiding mistaken deletion. Optionally, if the target application is not in the uninstalled state, that is, the user needs to continue using the application, the first file is reserved.
Fig. 2 is a schematic flowchart of another file attribution information recording method according to an embodiment of the present application, where the method includes the following steps:
Illustratively, the default virtual file system is the SDcardFS file system. A preset function, such as SDcardFS- > SDcardFS _ create function, may be added at the SDcardFS file system level in advance, and the function is used for listening to file creation requests.
For example, the application program to which the creation operation is initiated may be determined according to the process identifier of the application process, and thus the target application program may be determined.
And step 204, acquiring the identity information of the target application program to obtain the attribution information of the first file.
For example, the identity information may be a uid corresponding to the application, and the uid is taken as attribution information of the first file.
Illustratively, the underlying file system may be EXT4 or F2 FS.
And step 207, determining the management policy of the first file according to the attribution information.
According to the file attribution information recording method provided by the embodiment of the application, a file creation request initiated by an application program through calling a file creation interface of an application layer is monitored through a preset function added in a preset virtual file system, a corresponding target application program is determined according to an initiator of the creation request, and the identity information of the target application program is recorded as the file attribution information into the extended attribute of the underlying file system, so that the accurate and persistent recording of the file attribution information is realized, and the application layer can conveniently acquire the file attribution information at any time and perform targeted management on the corresponding file.
Fig. 3 is a schematic flowchart of another file attribution information recording method according to an embodiment of the present application, where the method includes:
For example, a preset function, such as SDcardFS- > SDcardFS _ create function, may be added to the SDcardFS file system layer in advance, and the function is used for listening to a file creation request.
Illustratively, the creation request is initiated by the application process, and when the creation request reaches the SDcardFS file system layer, the uid of the application program corresponding to the application process can be obtained through the current _ uid interface.
And step 304, recording the acquired uid as attribution information of the first file into an extended attribute of EXT 4.
In the embodiment of the present application, EXT4 may also be F2 FS.
Generally, in order to effectively manage files in a terminal, a housekeeping application program may be installed, where the application program may be an application program installed by default when the terminal leaves a factory, or a third-party application program downloaded and installed by a user, and the application program may have a variety of names, such as "file housekeeping", "cell phone housekeeping", and "garbage cleaning master", and all belong to the file housekeeping application program described in the embodiments of the present application.
For example, kernel may open a section of memory buffer in the expanded attribute xattr of the EXT4 or F2FS file system, and the SDcardFS file system may store the obtained string of the uid of the application in the buffer, and fetch the uid from the memory buffer of the corresponding node when necessary.
Fig. 4 is a schematic diagram of a file attribution information recording and acquiring process according to an embodiment of the present disclosure, and as shown in fig. 4, when an application creates a file, a uid of the application is automatically recognized, and the uid is recorded in an extended attribute of an underlying file system through an SDcardFS file system, and when a management application such as a manager needs to acquire the uid, the uid is acquired from the extended attribute by calling a preset interface in the SDcardFS file system.
For example, a white list of the application programs may be set, information (such as a name or a uid) of the currently installed application program in the terminal is maintained in the white list, and when it is detected that the first application program is uninstalled, the information corresponding to the first application program is deleted in the white list. When judging whether the target application program is in the uninstalled state, inquiring in a white list, and if the information corresponding to the target application program is not inquired, indicating that the target application program is uninstalled and is in the uninstalled state.
And 307, deleting the first file through the file manager application program.
When the target application program is determined to be uninstalled, it is indicated that the user does not need to use the target application program any more, the file belonging to the target application program also becomes a garbage file to be cleaned, generally, the unloaded residual file is cleaned in time, the storage space of the terminal can be effectively saved, and the system burden is reduced.
And 308, displaying an icon of the target application program at a position corresponding to the first file in the file manager application program.
For example, there may be some inherent display logic in the file manager application program to display the scanned files in a sorted manner, such as in a sorted manner according to a file format, so as to facilitate a user to see which application program each file belongs to, and to display an icon of the application program to which the current file belongs at a corresponding position (e.g., in front of or behind a file name) of the current file.
The method for recording the file attribution information, provided by the embodiment of the application, acquires the attribution information of a file when the file is created and records the attribution information into the extended attribute of a bottom layer file system, so that the accurate and persistent recording of the file attribution information is realized, when a housekeeping application program needs to acquire the attribution information of the file, a uid of an application program serving as the attribution information is acquired from the bottom layer file system, the file is subjected to targeted processing according to whether the corresponding application program is in an uninstalled state, and a file management scheme in a terminal is optimized.
