The names of messages or information exchanged between devices in the embodiments of the present disclosure are for illustrative purposes only, and are not intended to limit the scope of the messages or information.
In order to solve the problems that when an application is located and created according to a file creation path which is pre-stored, a newly installed application cannot store the file creation path in time so that the created application cannot be determined, and when the application is actually created and a file is actually created, the file creation path is modified, and the created application cannot be determined, a file processing method is provided in the embodiment of the disclosure.
Fig. 1 is a flowchart illustrating a file processing method according to an embodiment of the present disclosure, where the file processing method may be executed by a file processing apparatus, where 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:
The file creation function may be understood as a method function that needs to be called when creating a file, for example, a function such as open, mkdir, create, and the like.
In this embodiment, since the creating application calls the file creating function when creating the target file, it is first required to monitor whether the preset file creating 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 an embodiment of the present disclosure, a hook function associated with the file creation function is constructed in advance, 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, it is considered that a call request for the file creation function is obtained, and then, the corresponding file creation function is called.
In another embodiment of the present disclosure, because the created target file is inevitably stored in the preset storage space of the terminal device, a memory change of the preset storage space may be detected, when it is detected that the memory of the current preset storage space is increased, it is determined whether the memory increase value is greater than a preset threshold value, and if the memory increase value is greater than the preset threshold value, it is determined that a call request of the target file to the preset file creation function is obtained.
And secondly, responding to a call request of a preset file creation function, and acquiring an originating application identifier and a file creation path corresponding to the call request, wherein the originating application identifier can be one or more of User Identification (UID), an application name, application icon information and the like of the application.
It should be emphasized that the file creation path in the present embodiment is the actual file creation path at the time of creation of the target file, and therefore, positioning its creation application based on the file creation path ensures the accuracy of positioning.
In an 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 successfully created is monitored, for example, whether the occupation of the file creation function by the target file is removed is monitored, if the occupation is removed, the target file is considered to be successfully created, and for example, whether the target file meets a preset integrity condition is checked, and if the target file is a picture, whether the picture is completely stored is checked.
In this embodiment, if the target file is successfully created, the initiating application identifier and the file creation path of the target file are obtained through a processing function preset in the file creation function, where the processing function is a preset function that can obtain the initiating application identifier and the file creation path of the corresponding target file.
It should be understood that the originating application identification may not uniquely correspond to the corresponding application, for example, when the originating application identification is a UID, if there are other applications sharing the UID, it is obvious that multiple creating applications may be located based on the originating application identification.
Therefore, in this embodiment, the target application package name for creating the 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, because the application package name refers to a software package name (code namespace) and is a package designated when the application is developed, the application package name has a unique corresponding relationship with the application, and the target identification information may be the application package name, and of course, if the originating application identifier and the application are in one-to-one correspondence, the originating application identifier may also be determined as the corresponding target application package name.
In one embodiment of the present disclosure, as shown in fig. 2, determining the target application package name according to the originating application identifier includes:
In this embodiment, it is determined whether there are multiple reference application package names corresponding to the originating application identifier, and if there are multiple reference application package names, it is obvious that a unique creating application cannot be located based on the corresponding originating application identifier.
In different application scenarios, the manner of determining whether the reference application package names corresponding to the originating application identifier are multiple is different, which is exemplified as follows:
in an embodiment of the present disclosure, if the originating application identifier is the UID, it is determined whether the UID belongs to the corresponding shared UID, and in some possible embodiments, the naming rules of the package name of the file sharing the UID are different by the system, for example, for a user of the shared UID corresponding to the UID1000, the corresponding application package name is shared.
In some possible embodiments, to ensure that/data/system/packages can query the application package name of the originating application identifier, a mapping relationship between the UID and the package name may 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, at a Java layer of the system, an API function getpackagsforuid directly obtains a package name from a UID, so that a corresponding application package name can be directly obtained through getpackagsforuid, if a corresponding terminal device is an Android system, the application package name is obtained at a Native C language layer, an/data/system/packages.list file in the Android system can be queried, mapping relationships between all application package names and corresponding UIDs are stored in the application package name, and the system updates the mapping relationship when an application is installed and uninstalled, so that the method adopted in this embodiment is to start a thread monitoring/data/system/packages.list change, and if there is a change, the content of the file is refreshed and the mapping relationship between the package names are read, and a query UID interface is provided for other modules, thereby providing a service of obtaining the application package name through the UID.
In some possible implementations, the mapping stored in the packages.list may be as follows, wherein 10222, 10217, 10121 correspond to UID in the following mapping.
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；
In this embodiment, if at least one reference application package name is one, since the application package name is uniquely corresponding to the application, the reference application package name can be directly determined as the target application package name.
Further, in an embodiment of the present disclosure, the method further includes:
In this embodiment, if the reference application package names are multiple, the target application package name capable of uniquely locating the creation application is further determined in the multiple target applications.
As mentioned above, the application package name is identification information uniquely corresponding to the application, and therefore, in the present embodiment, if the reference application package name is multiple, the preset application package name list/data/system/packages.list is queried to obtain multiple reference application package names corresponding to multiple reference application package names.
And 204, determining a target application package name in the plurality of reference application package names according to the preset auxiliary identification information.
In this embodiment, the target application package name is screened from the multiple reference application package names according to a preset selection policy, and the target application package name is determined as the target application package name of the target file.
In this embodiment, if at least one reference application package name is multiple, preset auxiliary identification information of the originating application identification is obtained, where the preset auxiliary identification information is unique identification information corresponding to the application, and the target application package name is determined in the multiple reference application package 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 thereof are as follows:
as a possible implementation manner, when the preset auxiliary identification information is an application icon, since an application corresponding to the application icon is unique, or when the preset auxiliary identification information is an application name, the corresponding application is also unique, in this embodiment, the application icon or the application name of the originating application identifier may be obtained, and the target application package name may be obtained based on the application icon or the application name.
In this embodiment, the calling time of an application calling a preset file creation function and the request time of each application occupying a network resource to send a request in the system may be obtained, if the calling time is matched with the request time, an application icon or an application name of the corresponding application is obtained, and a target application package name is obtained according to the application icon or the application name.
As another possible implementation manner, the setting of the extended attribute needs to be completed in an independent thread, rather than directly setting the extended attribute in the file creation interface function, because the setting of the extended attribute is also an interface function for calling the file system, which generates a nested call, so that in order to avoid the nested call, a separate first thread is used in the implementation to complete the setting function of the extended attribute.
In this embodiment, since the first thread is pulled up according to the call request of the relevant application, the corresponding thread identification information corresponds to the application indication displacement, and therefore, in this embodiment, the target application package name can be uniquely determined by the thread identification information. In this embodiment, the viewable/proc/thread number/cmdline node acquires the target application packet name, the acquisition function of a PID parameter (thread identification information) may be directly added to the file creation function, and if the originating application identifier corresponds to a plurality of reference application packet names, the PID is further used to read/proc/thread number/cmdline node to acquire the target application packet name, so that the application packet name can be uniquely determined.
In still another embodiment of the present disclosure, as shown in fig. 3, multiple application icon thumbnails for the target application may also be acquired, query information including the application icon thumbnails for the multiple target applications is displayed in a form of a popup window, 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 103, constructing an association relation between the target application package name and the file creation path.
In this embodiment, an association relationship between the target application package name and the 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, and if so, the association relationship is considered to be reliable, and thus, 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 not consistent 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, the target file is conveniently subjected to virus troubleshooting, whether the target file is maliciously moved is sensed in time, or the association relationship of the target file is updated and the like, and therefore, even if the storage position of the target file is updated, the accuracy of the association relationship is not influenced.
It should be noted that, in different application scenarios, in order to facilitate location creation of an application, the association relationship may be stored in a preset storage location, or, for convenience of query, may also be directly stored in a target file in a manner of extending an attribute.
The method comprises the steps that a target application package name of a creator of a file is stored in an extended attribute of the target file, the target application package name is unique in an Android system and can identify the application, if a terminal device is a Linux file system, a mechanism is provided for the corresponding extended attribute of the terminal device and is used for permanently associating Key value pairs to the target file, the extended attribute can be used for adding additional Key-value Key value pairs to the file, and the keys and the values are character strings and have certain length limitation. 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 or not, and relevant support such as an extended attribute namespace is required. File systems including btrfs, ext2, ext3, ext4, f2fs, JFS, Reiserfs, Lustrefs, and XFS all support EA. And the support of various file systems for the extended property is optional.
For example, if the system of the terminal device is Android 11, since the underlying file system of the Android 11 employs F2FS, this file system may already support extended attributes, for example, extended attributes such as user.xxx may be defined to complete some functions. However, in the Android system, all applications cannot directly access the F2FS file system, but two overlap sdcardfs and FUSE file systems are added on the F2FS file system, and FUSE is above sdcardfs. Within the platform's existing code, neither sdcardfs nor fuse file systems support extended attributes, and existing extended attribute permission checking mechanisms do not allow sdcardfs and fuse access, the extended attribute of user. Therefore, the following functions need to be implemented in this example: the package is used to store the name of the application package, the access rule of the attribute of trans is added, the attribute of trans is allowed to access across the file system, and the Fuse, sdcardfs and f2fs can all access the attribute of trans, in addition, in this embodiment, an extended attribute operation function of sdcardfs and Fuse file systems is also needed to be implemented, the actual storage of the extended attribute is in the f2fs file system, and the extended attribute correlation interfaces implemented by sdcardfs and Fuse file systems are all functions of transparent transmission forwarding, where, as shown in fig. 4, the Fuse layer accesses the sdcardfs layer and the sdcardfs layer accesses the f2fs layer.
In an 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 application requests for creating files may be arranged in a form of a message queue.
Therefore, in the embodiment, a key-value pair is generated according to the target application package name and the file creation path, wherein, as shown in fig. 6, the key may correspond to the target application package name, and the value corresponds to the file creation path, and the key-value pair is stored in the extended attribute of the target file, so that each target file carries a corresponding created application tag, thereby improving the efficiency of locating the created application.
And 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 separately stored in a related database.
In an embodiment of the present disclosure, in order to further facilitate obtaining of a corresponding target file, the surface traverses all files in the 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 the target file may be obtained according to the correspondence relationship based on the database, so that the target file is quickly searched and obtained. The storage of the database and the setting of the extended attribute also need to be finished in an independent second thread, and the processing flow is also the same, but the final result is to write the target application package name and the file creation path into the database.
In some possible embodiments, as shown in fig. 7, each row in the preset database stores a corresponding target application package name package and a file creation path, a path of the target file may be quickly determined based on the corresponding target application package name package, the target file may be quickly found according to the path of the target file, and operations such as downloading the target file may be implemented.
Therefore, as shown in fig. 8, in the embodiment of the present disclosure, the scheme includes a file creation interface module, an extended attribute setting module, a database saving module, and the like, where the file creation interface module is a file creation function for creating various files and folders provided by the file system, and includes open, mkdir, create, and the like, and the scheme needs to add a processing function into an interface of these file creation functions. The processing function is to send the initiation application identifier (UID in the embodiment) and the file creation PATH (PATH in the embodiment) calling the function to the extended attribute setting module and the database storage module, the extended attribute setting module receives the UID and PATH information transmitted by the file creation interface, the UID is converted into an application package name through the UID package name mapping relation, then the application package name is written into the extended attribute of the file corresponding to the PATH, the database storage module receives the UID and PATH information transmitted by the file creation 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 both written into the database.
Therefore, the identification information of the creator can be stored and saved in a peer-to-peer mode of adding an extended attribute key value in the extended attribute of the file system, and the identification information can be the name of the application package on the Android platform. When a file is created by an application, the application package name of the application is written into the extended attribute of the newly created file. Instead of recording the file path used by the application in advance, the information of the application is automatically recorded into the extended attribute of the file when the application creates the file, and then the information of the application 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 from 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 created application of the reference file, so that convenience in obtaining the created application of the file is improved. The preset corresponding relation stores the corresponding relation between the application package name and the corresponding application name for creating the application.
In order to improve the searching speed, a database is newly established at the same time, the package name of a target application and a file creating path are recorded, the database is updated at the same time when the extended attribute is updated, the function of saving the related information of a file creator can be automatically realized without any modification on related applications, the information of the file creator is in a file system, original information can still be kept by moving files, the original information can be added into the database to save the information, all files created by a certain application can be quickly obtained, and the like.
In this embodiment, in response to a query request for a file to be created for 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 an application need to be selected, all file paths can be directly read from the database, searching for a whole disk is avoided, and acquisition efficiency and accuracy of the created file are improved. In this embodiment, if it is desired to acquire a certain type of file created by a certain creating application, for example, it is desired to acquire all picture files created by a certain creating application, when all files are acquired, the file type of each file may also be identified, and all files of the corresponding type are screened out according to the file type. In summary, the file processing method according to the embodiment of the present disclosure, in response to a call request for a preset file creation function, obtains an originating application identifier and a file creation path corresponding to the call request, further determines a target application package name corresponding to the originating application identifier, constructs an association relationship between the target application package name and the file creation path, and stores the association relationship in a preset storage location. Therefore, when the file is created, the corresponding application identification and the creating path are recorded, the record omission of the file creation is avoided, the recording efficiency is improved, and in addition, the recorded actual creating path of the file is convenient for accurately determining the creating application of the file.
In order to implement the above embodiments, the present disclosure also provides a file processing apparatus.
