The embodiment of the application provides a method, a device, a computer device and a storage medium for managing file rights, and in particular, the method for managing file rights in the embodiment of the application can be executed by the computer device, where the computer device can be a terminal or a server. The terminal can be a terminal device such as a smart phone, a tablet computer, a notebook computer, a touch screen, a game machine, a personal computer (PC, personal Computer), a personal digital assistant (Personal Digital Assistant, PDA) and the like.
The embodiment of the application provides a method, a device, an electronic device and a storage medium for managing file rights, and the method, the device, the electronic device and the storage medium are described in detail below. The following description of the embodiments is not intended to limit the preferred embodiments.
The embodiment of the application provides a method for managing file rights, which can be executed by computer equipment.
Referring to fig. 1, fig. 1 is a flow chart of a method for managing file rights according to an embodiment of the present application, and the specific flow may be as follows steps 101 to 105:
101, acquiring a first process corresponding to a first application program in a simulator, and requesting a file access request of a second process corresponding to a second application program, wherein the file access request carries a target file path of a target file to be accessed, and the simulator is used for simulating a second operating system in a first operating system.
The simulator is a software program compiled on a computer platform and capable of simulating and executing a specific hardware platform and a program thereof. The simulator has a corresponding simulation system, for example, if the simulator is an android simulator, the simulator corresponds to the android simulation system, so that the simulator can run on a computer and simulate an android mobile phone system, and can install, use and uninstall software of an android application, so that a user can experience an android game and an application on the computer. Here, the devices configuring the simulator may be a computer, a cellular phone, a tablet computer, a game device, and the like. For example, the simulator in the embodiment of the present application is a star cloud engine, which is also called Nebula, and refers to a server engine that can be used to install a mobile game application (such as mu mobile game assistant, etc.). The star cloud engine can be provided with a plurality of application programs, and when the application programs run on the star cloud engine, each application program corresponds to one simulator instance and corresponds to one data path as a file system of the application program. Specifically, in the embodiment of the present application, the simulator is used to simulate the second operating system (Linux system) in the first operating system (Windows system).
In order to reduce the reading step of the permission information of the acquisition target file, before the step of acquiring the file access request of the first process corresponding to the first application program and the second process corresponding to the second application program in the simulator, the method may include:
when the first running simulator is detected, creating a permission file in a disk of the computer equipment, wherein permission information of all files corresponding to the simulator is stored in the permission file;
mapping the authority file into a memory space provided by a first operating system;
generating a file authority list and a plurality of file identifications based on authority information corresponding to all files in the authority files, file paths corresponding to all files and a hash algorithm, wherein the file identifications are associated with the corresponding authority information in the file authority list.
The hash algorithm adopted in the embodiment of the application is a Cuckoo hash algorithm (Cuckoo), and in the embodiment of the application, authority information and configuration files of file states of all files of a simulator stored in a disk of computer equipment are recorded by adopting the Cuckoo hash algorithm.
Optionally, the step of creating a rights file in a disk of the computer device when the first run of the simulator is detected, the method may comprise:
When the initial running simulator is detected, creating a blank file with a preset size in a disk of the computer equipment;
and storing the authority information of all files of the simulator in the blank file to obtain the authority file.
In a specific embodiment, the step of generating the file permission list and the plurality of file identifications based on the permission information corresponding to all files in the permission files, the file paths corresponding to all files and the hash algorithm may include:
acquiring a file path corresponding to each file to be processed in the authority files and authority information corresponding to each file to be processed in the authority files;
generating a file identifier based on a file path of the file to be processed and a hash algorithm;
storing the authority information corresponding to the file to be processed into a preset file list according to the file identification so as to generate a file authority list.
Specifically, a target storage position is determined in a preset file list based on a file identifier, and authority information corresponding to a file to be processed is stored in the target storage position to generate a file authority list.
For example, a simplified formula of the cuckoo hash algorithm provided in the embodiment of the present application may be:
Index＝Hash_func(Pathname)
Wherein Pathename represents the absolute path of a file in the simulator; hash_func represents cuckoo Hash calculation; index is a calculated Index value that can be identified as a file. For example, the rights files may be organized by a cuckoo hash algorithm into a 4096 row by 64 column table to form a file rights list. The index is used for representing a target row in a preset file list corresponding to a certain file, and after the target row is determined, the unused column is determined as a target column by enumerating 64 columns in the target row in the preset file list, so that the position for storing the authority information of the certain file is determined in the preset file list.
Since different files have different absolute paths, an absolute path refers to the actual path of a file on the disk of a computer device. The computer device may obtain different index after calculating the hash_func of the absolute paths of all files corresponding to the simulator. Then, judging the unused columns in the 64 columns of the corresponding rows in the preset file list, and storing the authority information in the preset file list in a one-to-one correspondence manner, so as to generate a file authority list.
In order to enable the file newly added by the synchronous update target process to be updated, the file authority list corresponding to the authority files shared by all the files is updated in real time, after generating the file authority list and a plurality of file identifications based on the authority information corresponding to all the files in the authority files, the file paths corresponding to all the files and the hash algorithm in the step:
when the target process is detected to be in an operating state and the target process creates a new file, storing the authority information of the new file into a file authority list to obtain an updated file authority list, wherein the target process is a first process and/or a second process;
and updating the rights file based on the updated file rights list to obtain an updated rights file.
In order to enable synchronous updating of the file permission list corresponding to the permission files shared by all files, after generating the file permission list and the plurality of file identifications based on permission information corresponding to all files in the permission files, file paths corresponding to all files and a hash algorithm in the step, the method may include:
modifying the first authority information of a file to be modified in a target process to obtain second authority information of the file to be modified, wherein the target process is a first process and/or a second process;
Updating the file authority list based on the second authority information of the file to be modified to obtain an updated file authority list;
and updating the rights file based on the updated file rights list to obtain an updated rights file.
According to the embodiment of the application, the same authority file can be mapped into different processes by utilizing the file mapping function of the operating system, so that the problem of cross-process sharing is solved. Since only one rights file is used, there is no need to process multiple files, so the file caching function of the operating system can be run very efficiently. Moreover, each file used in the operating system becomes a cache in a memory space, so that the files can be shared across processes; therefore, in the multi-process model, all processes can use the same rights file for caching in the memory control.
102, acquiring the target file identification based on the target file path.
Specifically, the target file path is an access path of the target file in the disk of the computer device, and the target file path is an absolute path of the target file, that is, a real path of the target file on the disk of the computer device. After the target file path is obtained, the computer device may calculate the target file path using a cuckoo hash algorithm to obtain the target file identifier. And then, determining target authority information corresponding to the target file identification based on a preset corresponding relation between the file identification and the authority information in the memory space.
And 103, determining target authority information of the target file from the memory space according to the target file identification, wherein the target authority information is used for indicating the application program with the access authority of the target file.
In a specific embodiment, the step of determining the target authority information of the target file from the memory space according to the target file identifier may include:
and determining target authority information from a file authority list according to the target file identifier, wherein the file authority list is positioned in a memory space provided by the first operating system and is composed of authority information of all files in the simulator.
104, determining whether the first application program is allowed to access the target file based on the target authority information.
Specifically, after the computer equipment acquires the target authority information, comparing and judging the first application program so as to determine whether the first application program can be allowed to access the target file, if not, requesting access failure, and if not, the first application program cannot be allowed to access the target file; and if the access permission is allowed, configuring the access permission of the target file for the first process so that the first process accesses the target file.
And 105, if the access permission is allowed, configuring the access permission of the target file for the first process so that the first process accesses the target file.
The embodiment of the application provides a file authority management method, which is characterized in that when a simulator is initially operated, an authority file is created in a disk of computer equipment, and all files corresponding to the simulator are stored in the authority file. Then, when the simulator is operated, the authority files can be mapped into the memory space, and when the authority information of the target file is determined, the read-write operation steps for determining the authority information of the target file can be reduced, so that the time for inquiring the authority information of the target file is shortened, and the efficiency for determining the authority information of the target file is improved.
In light of the foregoing, the following will further illustrate a method for managing file rights of the present application, by way of example. Referring to fig. 2, fig. 2 is a schematic flow chart of another method for managing file rights according to an embodiment of the present application, and the specific flow may be as follows steps 201 to 206:
and 201, acquiring authority information corresponding to all files in the star cloud engine to create an authority file.
When detecting that the star cloud engine is started for the first time in the computer equipment, the computer equipment creates a blank authority file with a preset size in a disk. The size standard of the file with the preset size is the file size calculated by a designer in predicting the maximum supported file number of the whole Windows system.
202, mapping the rights file to a memory space to generate a file rights list.
In a specific embodiment, based on rights information corresponding to all files in the rights file, file paths corresponding to the files, and a hash algorithm, a file rights list and a plurality of file identifications "are generated, and the method may include:
acquiring a file path corresponding to each file to be processed in the authority files and authority information corresponding to each file to be processed in the authority files;
generating a file identifier based on a file path of the file to be processed and a hash algorithm;
storing the authority information corresponding to the file to be processed into a preset file list according to the file identification so as to generate a file authority list.
Specifically, a target storage position is determined in a preset file list based on a file identifier, and authority information corresponding to a file to be processed is stored in the target storage position to generate a file authority list.
For example, a simplified formula of the cuckoo hash algorithm provided in the embodiment of the present application may be:
index＝hash_func(pathname)
wherein Pathename represents the absolute path of a file in the simulator; hash_func represents cuckoo Hash calculation; index is a calculated Index value that can be identified as a file. For example, the rights files may be organized by a cuckoo hash algorithm into a 4096 row by 64 column table to form a file rights list. The index is used for representing a target row in a preset file list corresponding to a certain file, and after the target row is determined, the unused column is determined as a target column by enumerating 64 columns in the target row in the preset file list, so that the position for storing the authority information of the certain file is determined in the preset file list.
Since different files have different absolute paths, an absolute path refers to the actual path of a file on the disk of a computer device. The computer device may obtain different index after calculating the hash_func of the absolute paths of all files corresponding to the simulator. Then, judging the unused columns in the 64 columns of the corresponding rows in the preset file list, and storing the authority information in the preset file list in a one-to-one correspondence manner, so as to generate a file authority list.
In the embodiment of the application, the authority file is regarded as a memory block, the authority file is mapped into a memory control when the star cloud engine is operated, and the content (authority information) in the authority file is organized into a cuckoo hash table irrelevant to the address. The technology of adopting the cuckoo hash table can solve the conflict of the hash table through a cuckoo conflict avoidance algorithm. Because pointers are not involved in the whole hash table, and the socket of each hash table and the hash table are of fixed length, mapping of the authority files in the memory space can be realized by organizing the whole data structure into the memory space with fixed length and no address. And, all operations of the computer equipment to the cuckoo hash table are cross-process lockless operations, only atomic operations are used as a synchronization means, and all operations to the cuckoo hash table can be updated immediately by other processes or threads.
203, storing the authority information of the newly added file created by the first game application program into a file authority list when the star cloud engine runs the first game application program.
In order to realize the synchronous updating of the newly added file of the target process, the file authority list corresponding to the authority files shared by all the files is updated in real time, and when the newly added file is created under the running state of the first game application program, the computer equipment can store the authority information of the newly added file into the file authority list so as to obtain the updated file authority list; and then updating the rights file based on the updated file rights list to obtain an updated rights file.
Optionally, in order to synchronously update the file permission list corresponding to the permission files shared by all the files, when the first permission information of the file to be modified in the first game application program is detected to be modified, second permission information of the file to be modified is obtained; updating the file authority list based on the second authority information of the file to be modified to obtain an updated file authority list; and updating the rights file based on the updated file rights list to obtain an updated rights file.
204, when the file access request of the first process corresponding to the first game application program in the simulator and the file access request of the second process corresponding to the second game application program is obtained, obtaining the target file path of the target file to be accessed carried by the file access request.
For example, a first game application requests access to a file in a second game application, the file path being/data/data/com. When a file access request of a first process corresponding to a first game application program in the simulator and a file access request of a second process corresponding to a second game application program are obtained, the computer device can obtain a target file path (/ data/data/com.netease.my/file) of a target file to be accessed carried by the file access request.
And 205, acquiring the target file identification based on the target file path.
In a specific embodiment, the computer device may obtain a file path (/ data/data/com.netease.my/file) of the file, and after obtaining the file path, the file path may be calculated using a cuckoo hash algorithm to obtain the file identifier.
And 206, determining target authority information of the target file from the file authority list according to the target file identification so as to determine whether the first application program is allowed to access the target file or not based on the target authority information.
The computer device may determine the authority information corresponding to the file identifier from the file authority list based on a preset correspondence between the file identifier and the authority information in the memory space. After the computer equipment acquires the target authority information, comparing and judging the first application program so as to determine whether the first application program can be allowed to access the target file, if not, requesting access failure, wherein the first application program cannot be allowed to access the target file; and if the access permission is allowed, configuring the access permission of the target file for the first process so that the first process accesses the target file.
