The names of messages or information interacted between the various devices in the embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of such messages or information.
In order to solve the problem that when a file creation path of an application is stored in advance, the creation application cannot be determined when the newly installed application does not store the file creation path in time when the creation application locates the creation application according to the file creation path created in advance, and the creation application cannot be determined when the file creation path is modified when the creation application actually creates a file, the embodiment of the disclosure provides a file processing method, in which real-time record of creation information about the file creation path and the like is performed in real time following the creation of the file, so that the accuracy and efficiency of the determination of the creation application are ensured, and the method is described below in connection with specific embodiments.
Fig. 1 is a flow chart of a method for processing a file according to an embodiment of the disclosure, where the method may be performed by a file processing apparatus, and the apparatus may be implemented by software and/or hardware, and may be generally integrated in an electronic device. As shown in fig. 1, the method includes:
Step 101, acquiring an initiating application identifier and a file creation path in response to a call request of a preset file creation function.
The file creation function may be understood as a method function that needs to be called when creating a file, for example, functions such as open, mkdir, create, and the like.
In this embodiment, since the related creation application calls the file creation function when creating the target file, it is first required to monitor whether the preset file creation function is called.
In different application scenarios, the manner of monitoring whether the preset file creation function is called is different, and examples are as follows:
in one embodiment of the present disclosure, a hook function associated with a file creation function is pre-constructed, for example, a call address of the file creation function may be modified to a call address of the hook function, and when the hook function is called, a call request to the file creation function is considered to be acquired, and a corresponding file creation function is called.
In another embodiment of the present disclosure, since the created target file is necessarily stored in the preset storage space of the terminal device, a memory change of the preset storage space may be detected, when a memory increase of the current preset storage space is detected, it is determined whether the memory increase value is greater than a preset threshold, and if so, it is considered that a call request of the target file to the preset file creation function is acquired.
Secondly, responding to a call request of a preset file creation function, and acquiring an initiating application identifier and a file creation path corresponding to the call request, wherein the initiating application identifier can be one or more of user identification (User Identification, UID) of an application, an application name, application icon information and the like.
It is emphasized that the file creation path in the present embodiment is an actual file creation path at the time of creation of the target file, and therefore positioning the creation application thereof based on the file creation path ensures the accuracy of positioning.
In one embodiment of the present disclosure, in order to further determine that the file creation path is an actual file creation path when the target file is created, whether the target file is created successfully is monitored, for example, whether occupation of the file creation function by the target file is released is monitored, if so, the target file is considered to be created successfully, for example, whether the target file meets a preset integrity condition is checked, if so, whether the picture is saved completely is checked, and the like.
In this embodiment, if the creation of the target file is successful, the processing function is a function that can obtain the initiation application identifier and the file creation path of the corresponding target file through presetting a processing function in the file creation function, so as to obtain the initiation application identifier and the file creation path of the target file.
Step 102, determining a target application package name corresponding to the initiating application identifier.
It should be appreciated that the originating application identification may not uniquely correspond to the corresponding application, e.g., when the originating application identification is a UID, if there are other applications sharing the UID, it is apparent that multiple created applications may be located based on the originating application identification.
Therefore, in this embodiment, the target application package name of the creating application is determined based on the originating application identifier, and the target application package name may be understood as identification information uniquely corresponding to the application, for example, since the application package name refers to a software package name (code naming space) and is a package specified when the application is developed, the target application package name may be the application package name, or the like, and if the originating application identifier and the application are in one-to-one correspondence, the originating application identifier may be determined as the corresponding target application package name.
In one embodiment of the present disclosure, as shown in fig. 2, determining a target application package name according to an originating application identifier includes:
step 201, inquiring a preset application package name list according to an initiating application identifier to obtain at least one reference application package name.
In this embodiment, it is determined whether the reference application packet name corresponding to the originating application identifier is plural, and if plural, it is obvious that the unique creating application cannot be located based on the corresponding originating application identifier.
In different application scenarios, the ways of judging whether the reference application packet names corresponding to the originating application identifier are multiple are different are exemplified as follows:
in one embodiment of the present disclosure, if the originating application identifier is a UID, it is determined whether the UID belongs to a corresponding shared UID, and in some possible embodiments, naming rules of package names of files sharing the UID are different, for example, for a shared UID user corresponding to UID1000, the corresponding application package name is shared.
In some possible embodiments, in order to ensure that the application package name of the originating application identifier can be queried by the data/system/packages, the mapping relationship between the UID and the package name can be maintained in real time, so as to query the application package name of each originating application identifier according to the mapping relationship.
In this embodiment, in the Java layer of the system, the API function getpackagsforuic directly obtains the package name from the UID, so that the corresponding application package name can be directly obtained through the getpackagsforuic, if the corresponding terminal device is an Android system, and the application package name is obtained in the Native C language layer, the mapping relationship between the package names of all applications and the corresponding UIDs can be queried, and the mapping relationship can be updated when the application is installed and uninstalled, so that the method adopted in this example is to start a change of thread monitoring/data/system/packages, and if the change is, the mapping relationship between the content UID and the package name of the file is read, and query interfaces are provided to other modules, so that services for obtaining the application package name through the UID are provided.
In some possible implementations, the mapping relationship stored in the packages, list, may be as follows, where 10222, 10217, 10121 correspond to the UID in the mapping relationship described below.
com.smartisanos.writer 10122 1/data/user/0/com.smartisanos.writer platform:targetSdkVersion＝27 3003 1 1；
com.achievo.vipshop10217 0/data/user/0/com.achievo.vipshop default:targetSdkVersion＝28 3002,3003 0 70704；
com.smartisanos.share.browser101210/data/user/0/com.smartisanos.sh are.browser default:targetSdkVersion＝17 3003 0 1；
Step 202, if at least one reference application package name is one, determining that the corresponding reference application package name is the target application package name.
In this embodiment, if at least one reference application package name is one, since the application package name corresponds to the application uniquely, the reference application package name may be directly determined as the target application package name.
Further, in an embodiment of the present disclosure, the method further includes:
step 203, if at least one reference application packet name is multiple, acquiring preset auxiliary identification information of the originating application identification.
In this embodiment, if the reference application package name is plural, the target application package name that can uniquely locate the creation application is further determined in the plural target applications.
As mentioned above, the application package name is identification information uniquely corresponding to the application, so in this embodiment, if the reference application package name is plural, the preset application package name list/data/system/packages is queried to obtain plural reference application package names corresponding to the plural reference application package names.
And 204, determining the target application package name in a plurality of reference application package names according to the preset auxiliary identification information.
In this embodiment, a target application package name is selected from a plurality of reference application package names according to a preset selection policy, and the target application package name is determined to be a target application package name of a target file.
In this embodiment, if at least one reference application packet name is multiple, preset auxiliary identification information of an originating application identification is obtained, the preset auxiliary identification information is unique identification information corresponding to an application, and a target application packet name is determined from the multiple reference application packet names according to the preset auxiliary identification information.
It should be noted that, in different application scenarios, the preset auxiliary identification information is different, and examples are as follows:
as a possible implementation manner, when the preset auxiliary identifier information is an application icon, since the application corresponding to the application icon is unique, or when the preset auxiliary identifier information is an application name, the corresponding application is also unique, so in this embodiment, the application icon or the application name that initiates the application identifier may be acquired, and the target application package name may be acquired based on the application icon or the application name.
In this embodiment, the call time of an application calling a preset file creation function and the request time of each application in the system for occupying network resources to send a request may be obtained, if the call time matches with the request time, an application icon or an application name of the corresponding application may be obtained, and a target application package name may be obtained according to the application icon or the application name.
As another possible implementation, setting the extension attribute needs to be done in a separate thread, instead of setting the extension attribute directly in the file creation interface function, because setting the extension attribute is also an interface function that invokes the file system, thus creating a nested call, so to avoid the nested call, a separate first thread is used in this implementation to accomplish the function of setting the extension attribute.
In this embodiment, since the first thread is pulled up according to the call request of the related application, the corresponding thread identification information corresponds to the application indication displacement, and thus, in this embodiment, the target application packet name can be uniquely determined by the thread identification information. In this embodiment, the target application packet name may be obtained by checking/proc/thread number/cmdline node, and an obtaining function of PID parameter (thread identification information) may be directly added to the file creation function, if the originating application identifier corresponds to multiple reference application packet names, the target application packet name may be further obtained by reading/proc/thread number/cmdline node through PID, so that the application packet name may be uniquely determined.
In still another embodiment of the present disclosure, as shown in fig. 3, a plurality of application icon thumbnails for targets may be further obtained, query information including the application icon thumbnails of the plurality of target applications is displayed in a pop-up window form, and an application identifier corresponding to the application icon thumbnail triggered by the user is selected as a target application package name according to a triggering operation of the user.
And step 103, constructing the association relation between the name of the target application package and the file creation path.
In this embodiment, an association relationship between a target application package name and a file creation path is constructed, so that it can be further verified based on the file creation path in the association relationship, whether the current file storage path of the queried target file is consistent with the file creation path in the association relationship, if so, the association relationship is considered to be reliable, and therefore, the creation application of the corresponding file is determined based on the target application package name in the association relationship. If the current file storage path of the target file is inconsistent with the file creation path in the association relationship, the corresponding target file is considered to move, so that alarm information and the like are sent, virus investigation processing is conveniently carried out on the target file, whether the target file is maliciously moved or not is timely perceived, or the association relationship of the target file is updated, and the like, so that the accuracy of the association relationship is not affected even if the storage position of the target file is updated.
It should be noted that, in different application scenarios, in order to facilitate positioning and creating an application, the above-mentioned association relationship may be stored in a preset storage location, or in order to facilitate querying, may also be directly stored in the target file in a manner of extending the attribute.
The method comprises the steps that a target application package name of a creator of a target file is stored in an extension attribute of the target file, the target application package name is unique in an Android system and can identify an application, if a terminal device is a Linux file system, the corresponding extension attribute provides a mechanism for permanently associating a Key value pair with the target file, the extension attribute can add an additional Key-value Key value pair to the file, and the Key and the value are character strings and have a limit of a certain length. The extended attribute needs support of an underlying file system, and when the extended attribute is used, a file system description article needs to be checked to see whether the file system supports the extended attribute, and relevant support of an extended attribute naming space and the like. File systems including btrfs, ext2, ext3, ext4, f2fs, JFS, reiserfs, lustrefs, and XFS all support EA. While various types of file systems are optional for support of extended properties.
For example, if the system of the terminal device is Android 11, since the underlying file system of Android 11 adopts F2FS, this file system may already support extended attributes, for example, extended attributes such as user. However, in the Android system, all applications cannot directly access the F2FS file system, but two Overlay-property sdcardfs and FUSE file systems are added on the F2FS file system, and FUSE is on the sdcardfs. Within the platform existing code, neither the sdcarbfs nor the fuse file system supports extended attributes, nor the existing extended attribute permission checking mechanism allows sdcarbfs and fuse access, extended attributes of user. Thus, the following functions need to be implemented in this example: the trans-package is added to save the application package name, the access rule of the trans-attribute is added, the trans-attribute is allowed to access across the file system, the Fuse, the sdcarbfs and the f2fs can access the trans-attribute, in addition, in the embodiment, the operation functions of the sdcarbfs and the extended attribute of the Fuse file system are also needed to be realized, the actual saving of the extended attribute is the function of transparent forwarding in the f2fs file system, and the related interfaces of the extended attribute realized by the sdcarbfs and the Fuse file system are all functions of transparent forwarding, wherein, as shown in fig. 4, the sdcarbfs layer is accessed by the Fuse layer, and the f2fs layer is accessed by the sdcarbfs layer.
In the independent first thread, as shown in fig. 5, a file processing request is generated in response to a call request of a target file to a preset file creation function, and the file creation application request may be arranged in a message queue.
Thus, in this embodiment, a key value pair is generated according to the destination application package name and the file creation path, where, as shown in fig. 6, the key may correspond to the destination application package name, the value corresponds to the file creation path, and the key value pair is stored in the extended attribute of the destination file, so that each destination file carries a corresponding creation application label, and efficiency of positioning the creation application is improved.
Step 104, storing the association relation in a preset storage position.
In this embodiment, the association relationship is stored in a preset storage location, for example, a key value pair is stored in an extended attribute of the target file, or the association relationship may be stored separately in a related database.
In one embodiment of the present disclosure, in order to further facilitate obtaining a corresponding target file, the surface traverses all files in a disk, and may further store an association relationship between a target application package name and a file creation path in a preset database, where the preset database may be stored in a cloud server, and based on the database, the target file may be obtained according to the correspondence relationship, so as to implement quick search and obtaining of the target file. The storage of the database and the setting of the extended attribute are required to be completed in a second independent thread, and the processing flow is the same, but the final result is that the name of the target application package and the file creation path are written into the database.
In some possible embodiments, as shown in fig. 7, each row in the preset database stores a corresponding destination application package name package and a file creation path, and the path of the destination file can be quickly determined based on the corresponding destination application package name package, so that the destination file can be quickly found according to the path of the destination file, and operations such as downloading the destination file can be realized.
Thus, as shown in fig. 8, in the embodiment of the present disclosure, the solution includes a file creation interface module, an extended attribute setting module, and a database saving module, where the file creation interface module is a file creation function for creating various files and folders provided by a file system, and includes open, mkdir, create, and the like, and a processing function needs to be added into the interfaces of these file creation functions. The processing function sends an initiating application identifier (UID in the embodiment) and a file creating PATH (PATH in the embodiment) for calling the function to an extended attribute setting module and a database storing module, the extended attribute setting module receives UID and PATH information transmitted by a file creating interface, the UID is converted into an application package name through a UID package name mapping relation, then the application package name is written into an extended attribute of a file corresponding to the PATH, the database storing module receives the UID and the PATH information transmitted by the file creating interface, the UID is converted into the application package name through the UID package name mapping relation, and then the application package name and the PATH are written into a database.
Therefore, the identification information of the creator can be stored and saved by adding an extended attribute key value peer-to-peer mode in the extended attribute of the file system, and the identification information can be an application package name in the Android platform. When an application creates a file, the application package name of the application is written into the extension attribute of the newly created file. Instead of recording the file path used by the application in advance, the application's information is automatically recorded into the extended attributes of the file when the application creates the file, and then the application's information is associated with the file until the file is deleted.
In this embodiment, in response to an application query request for a first reference file, a first reference application package name is obtained in an extended attribute of the first reference file, and then a preset corresponding relationship is queried according to the first reference application package name to determine a creation application of the reference file, thereby improving convenience in obtaining the creation application of the file. The preset corresponding relation stores the corresponding relation between the application package name and the corresponding application name of the created application, and the like.
In order to improve the searching speed, a database is newly built at the same time, the name of a target application package and a file creating path are recorded, the database is updated at the same time when the extension attribute is updated, the related application does not need to be modified, the function of storing related information of a file creator can be automatically realized, the information of the file creator is in a file system, the original information can still be kept by a mobile file, the database is added to store the information, all files created by a certain application can be quickly acquired, and the like.
In this embodiment, in response to a request for querying a file created by a reference application, a second reference application package name of the reference application is obtained, and then, according to a preset database, at least one second file storage path matched with the second reference application package name is obtained, and at least one second reference file is obtained according to the second file storage path, so that if all files created by a certain application need to be selected, all file paths can be directly read from the database, searching of the whole disk is avoided, and the efficiency and accuracy of obtaining the created file are improved. In this embodiment, if it is desired to obtain a certain type of file created by a certain creation application, for example, it is desired to obtain all picture files created by a certain creation application, when all files are obtained, the file type of each file may be identified, and all files of the corresponding type are selected according to the file type. In summary, in the file processing method according to the embodiment of the present disclosure, in response to a call request for a preset file creation function, an originating application identifier and a file creation path corresponding to the call request are obtained, and further, a target application package name corresponding to the originating application identifier is determined, an association relationship between the target application package name and the file creation path is constructed, and the association relationship is stored in a preset storage location. Therefore, when the file is created, the corresponding application identifier and the creation path are recorded, so that record omission of file creation is avoided, the recording efficiency is improved, in addition, the recorded actual creation path of the file is convenient for accurately determining the file creation application.
In order to implement the above embodiment, the present disclosure further proposes a file processing apparatus.
