All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Optionally, as an optional implementation manner, as shown in fig. 1, the file cleaning method includes:
s102, acquiring a target file list of all file information in a target file system recorded with target file information, wherein the file information comprises file cleaning information configured for a file in advance, and the file cleaning information is used for indicating that the file is allowed to be cleaned;
s104, determining first file cleaning information matched with preset target cleaning conditions in the file cleaning information of the target file information;
and S106, cleaning the target file corresponding to the first file cleaning information in the target file system.
Optionally, the file cleaning method may be applied, but not limited to, in a scenario of automatically cleaning App sandbox waste files, specifically, by taking over addition and deletion of App sandbox waste files, and attaching a "cleaning attribute" to each file created through the method to identify a deletion policy for the file, based on which the file cleaner can perform an automatic cleaning operation at an appropriate time.
Optionally, in this embodiment, the preset target cleaning condition may include, but is not limited to, at least one of the following: a time condition, a storage condition, a call condition, etc., wherein the time condition may be, but is not limited to, determining a clean time of the file in terms of a system time, such as when the file clean information indicates that at system time "2021.02.03.13: 00' cleaning, if the system time reaches or exceeds, executing automatic cleaning operation to the file; the storage condition may be, but is not limited to, determining a cleaning condition of the file according to the system storage space, for example, in a case that a margin of the system storage space is less than or equal to a preset lower limit, the file is cleaned preferentially; the calling condition may be, but not limited to, according to the calling frequency of the file, or the recent calling number, for example, in a period of one month, and when the period is reached, the file with the calling frequency less than or equal to the preset frequency is automatically cleaned. This is by way of example only and not by way of limitation.
It should be noted that, an object file list of all file information in an object file system recorded with object file information is obtained, where the object file information is file information in the object file system, the file information includes file cleaning information preconfigured for a file, and the file cleaning information is used to indicate that the file is allowed to be cleaned; determining first file cleaning information matched with preset target cleaning conditions in file cleaning information of target file information; and cleaning the target file corresponding to the first file cleaning information in the target file system.
Optionally, in this embodiment, the target file in the target file system does not need to be cleaned manually, but the corresponding file cleaning information is allocated to the target file when the target file is established, so that the system automatically cleans the target file when the file cleaning information matches the target cleaning condition. The file cleaning method enables a developer to only concern about the creation and the use of the file, and generally does not need to concern about the deletion of the file; on the other hand, the file cleaning method can delete the abandoned files in the target file system in time and release the storage space of the terminal in which the target file system is located.
For further example, as shown in fig. 2, the target file list 202 records a file a, a file B, and a file C of the target file system, wherein, while the file a, the file B, and the file C are established, the user may select that the file a, the file B, and the file C are each configured with corresponding file cleaning information, in other words, the file a, the file B, and the file C are each configured with corresponding file cleaning information, and the file cleaning information is used to instruct that the corresponding file is automatically cleaned at a time that the user wants to delete the file most.
Optionally, in this embodiment, for example, as shown in fig. 2, it is assumed that the file cleaning information of the file C matches the current preset target cleaning condition, and further it is determined that the file C is the target file 204, in other words, the file C is taken as the file that needs to be cleaned currently.
Optionally, in this embodiment, the file cleaning information pre-configured for the file may be, but is not limited to, executed by a file manager (FileManager), the file information may be, but is not limited to, stored in a Database (Database), the file of the target document system may be, but is not limited to, stored in a document system (Filesystem), the file cleaning method may be, but is not limited to, executed by a file cleaner (FileCleaner), the file is added and deleted by taking over the addition and deletion of the file, and a "cleaning attribute" is attached to each file created by the file cleaner, so as to identify a deletion policy for the file; based on the above, the file cleaner performs automatic cleaning work in due time.
Optionally, in this embodiment, only one FileCleaner instance needs to exist in the lifecycle of the target file system, which may be implemented as a single instance, and after the FileCleaner creation is completed, the FileCleaner starts the automatic cleaning work, which may, but is not limited to, occur only in the background thread. fileCleaner works by executing a run loop.
The start of the run loop occurs each time the target file system starts or a timed task triggers. The timed task means that the fileCleaner sets a Timer (Timer) at the end of each execution of a run cycle, and executes the next run cycle after the duration n, which is the case when the target file system is in a long life cycle.
In practice, on the one hand, the cleaning of obsolete files is not a high priority or time-sensitive task; on the other hand, both file and database operations are relatively resource consuming, so here the choice is made to be performed each time the target file system is started or a timed task is triggered.
After the running cycle begins, FileCleaner queries the private database to obtain a list of files that need to be cleaned. The query condition is combined with the information of the clearing attribute, the creation time, the last automatic clearing time and the like of each file.
When the file to be cleaned is inquired, cleaning operation is executed, otherwise, the next step is carried out, and the specific operation cycle is as follows:
1. and deleting the corresponding file in the file system according to the searched list of the files to be cleaned.
2. The FileCleaner receives the feedback that the file deletion is finished.
3. FileCleaner deletes the associated record for the cleared file in the private database.
4. FileCleaner records the current time in a dedicated database as the time when the automatic clean was last performed.
And setting a timer after the time length n, and triggering the operation cycle of the next round.
For further example, as shown in fig. 3, the following steps may be optionally performed:
step S302, creating a file cleaner 302;
step S304, under the condition that the file cleaner 302 is finished, the file cleaner 302 starts automatic cleaning;
step S306, inquiring file cleaning information stored in the database 304;
step S308, the file cleaner 302 deletes the file stored in the document system and corresponding to the file cleaning information;
step S310, the file cleaner 302 deletes the corresponding record stored in the database 304;
in step S312, the file cleaner 302 records the current time for cleaning the file in the database 304.
The optional steps S306 to S312 are running cycles started after the step S304 is executed, and after each running cycle is executed, the current time is used as the start time to start timing until the timing reaches the period of the running cycle, and then the next running cycle is started.
Optionally, in this embodiment, before obtaining the target file list of all file information in the target file system recorded with the target file information, or in the process of obtaining the target file list of all file information in the target file system recorded with the target file information, or after obtaining the target file list of all file information in the target file system recorded with the target file information, the target file list of the target file system may be updated in real time by adding a new file, for example, as shown in fig. 4, the specific steps are as follows:
in step S402, the user 402 sends a request for creating a file to the file manager 404, and 2 necessary parameters are introduced: url of file and "clear attribute" of file;
step S404, after receiving the request, the file manager 404 creates a file in the document system 406, wherein the url of the file is the url transmitted by the user 402;
step S406, the document manager 404 receives feedback of successful document creation;
step S408, the file manager 404 stores the url, the removal attribute, the creation date and other information of the file into a special database 408;
in step S410, the document manager 404 receives feedback of the completion of the storage in the database 408;
in step S412, the document manager 404 returns the document creation success to the user 402.
Optionally, in this embodiment, while executing the file cleaning method, the file may also be, but is not limited to, deleted by a user actively, optionally, a request for the user to delete the file actively is taken over, and the file manager processes the request uniformly, so as to delete information such as the file additional attribute in the dedicated database, for example, as shown in fig. 5, the specific steps are as follows:
step S502, the user 502 sends a request for deleting the file to the file manager 504, and the url of the file is transmitted;
step S504, after the file manager 504 receives the request, the corresponding file is deleted in the file system 506;
in step S506, the document manager 504 receives a feedback of successful document deletion;
step S508, the file manager 504 deletes the additional attribute information of the file in the private database 508;
step S510, the document manager 504 receives feedback of successful operation of the database 508;
in step S512, the document manager 504 returns the document deletion success to the user.

After the running cycle begins, FileCleaner queries the private database to obtain a list of files that need to be cleaned. The query condition is combined with the information of the clearing attribute, the creation time, the last automatic clearing time and the like of each file.
When the file to be cleaned is inquired, cleaning operation is executed, otherwise, the next step is carried out, and the specific operation cycle is as follows:
1. and deleting the corresponding file in the file system according to the searched list of the files to be cleaned.
2. The FileCleaner receives the feedback that the file deletion is finished.
3. FileCleaner deletes the associated record for the cleared file in the private database.
4. FileCleaner records the current time in a dedicated database as the time when the automatic clean was last performed.
And setting a timer after the time length n, and triggering the operation cycle of the next round.
