Background
In daily development needs, the following similar scenarios are often encountered: the system mainly carries out business processing around file resources, and the system can be divided into modules A, B, C. Suppose that the resource originally entered the system is file f0, and after a processing, the output is file f 1. f1 as input to the B module, which processes the output file f2 ….
On the basis, resources used or produced by each module need to support users to independently manage the modules, for example, when a certain processing task in the module a is deleted, the related input and output also need to be deleted synchronously. If the output of the processing task is already used for the B module, the deletion of the content does not influence the correct execution of the related processing task in the B module, and the system does not have residual garbage during operation.
In order to solve the above problem, the following two schemes can be generally adopted: the first scheme is to copy the input resources of each module dependence, and each module manages its dependence; the second solution is to implement a resource reference management module, which is used to manage the dependent resources in each module, and perform garbage cleaning work when a certain resource reference is 0.
However, with the first scheme, since the copied files are consistent in content, copying all input resources occupies a doubled storage space, which results in waste of hard disk resources. By adopting the second scheme, the resource reference management can increase the code coupling of each module, the dependence management difficulty is high, the error probability is high, the garbage cleaning is carried out according to the reference, the accident situation is easy to occur, and the accuracy is reduced.
Aiming at the problems that the system cost is increased and the processing accuracy is reduced because file resources are processed in a mode of copying the file resources or adding a resource reference management module in the related art, an effective solution is not provided at present.

Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
First, some technical features in the embodiments of the present invention are explained as follows:
hard linking: hardlink, which is one or more file names of a file. The file name and the node number used by the computer file system are linked, so that a plurality of file names can be linked with the same file.
MD 5: message Digest Algorithm MD5, the fifth version of the Message Digest Algorithm, operates data (e.g., chinese characters) into another fixed length value, is a widely used hash function in the field of computer security to provide integrity protection for messages.
Example 1
In accordance with an embodiment of the present invention, there is provided a method for processing a file resource, it should be noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
Fig. 1 is a flowchart of a processing method of a file resource according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S102, when the original file resource needs to be deleted, acquiring the quantity of hard links pointing to the original file resource, wherein the hard links are created between the processing module for referring to the original file resource and the original file resource;
step S104, judging whether the number of the hard links is less than a preset value;
and step S106, if so, deleting the original file resource.
In a system for performing business processing mainly around file resources, since the system is divided into a plurality of processing modules in advance, a user needs to be supported to delete file resources that each processing module depends on (also called as references), and since a file resource that one processing module depends on may also be depended on by other processing modules, after deleting the file resource that one processing module depends on according to the requirement of the other processing module, the other processing modules that depend on the file resource cannot work normally. In order to conveniently delete the file resources depended on by a certain processing module and not influence the normal operation of other processing modules related to the certain processing module, the file resources of each processing module are managed by means of the hard links, namely, the file resources are quoted by creating the hard links, and the file resources can still be quoted without copying the file resources. The original file resource may be file data actually stored in the system.
Additionally, based on the nature of the hard link, creating a hard link will increase the reference count of the original file resource, which now has at least one reference count. When the original file resource depended by a certain processing module is deleted, the hard link for referring to the original file resource is deleted, the reference count of the original file resource is reduced, and when the number of the hard links for referring to the original file resource is reduced to 0, the original file resource is referred to by no module in the system, the reference count of the original file resource is 1, and the original file resource is automatically deleted by the system. Therefore, the above preset value may be 1.
For example, the present invention will be described in detail by taking the system divided into two modules, module 1 and module 2. Files stored in the system are f0, f1 and f2, f0 is input into the module 1, and the module 1 outputs f 1; f1 is input into module 2, and module 2 outputs f 2. After the hard links are created, the number of hard links of f0 is 1, the number of hard links of f1 is 2, and the number of hard links of f2 is 1. When file resources f0 and f1 depended on by module 1 need to be deleted, the number of hard links of f0 and f1 can be obtained, at this time, the number of hard links of f0 is reduced to 0 (i.e. the reference count of f0 is reduced to 1), and the number of hard links of f1 is reduced to 1 (i.e. the reference count of f1 is reduced to 2), so that the system can delete file f 0.
By adopting the embodiment of the invention, when the original file resource needs to be deleted, the number of the hard links pointing to the original file resource can be acquired, and when the number of the hard links is less than the preset value, the original file resource is deleted, thereby realizing the purpose that the processing module manages the file resource independently. Because the hard link is created between the processing module for quoting the original file resource and the original file resource, the original file resource does not need to be copied, and the hard disk resource cannot be occupied by times, thereby solving the technical problems that the file resource is processed in a mode of copying the file resource or adding a resource quoting management module in the related art, the system cost is increased, the processing accuracy is reduced, and the technical effects of saving the hard disk resource, reducing the code coupling degree of each processing module and improving the stability of the system are achieved.
Optionally, in the above embodiment of the present invention, the method further includes: receiving the uploaded original file resources; storing original file resources; determining a processing module needing to refer to original file resources; a hard link is created for each processing module to point to the original file resource such that the processing module references the original file resource through the hard link.
When a user uploads or copies an original file resource to the system, the system can store the original file resource, and processing modules needing to refer to the original file resource all create a hard link from the original file resource and share the same data with the original file resource. Thus, the file under this directory has at least one reference count.
Optionally, in the above embodiment of the present invention, before storing the original file resource, the method further includes: judging whether the file name of the original file resource already exists; if not, storing the original file resource; if so, the storage operation on the original file resource is ignored.
Because the original file resources uploaded or copied by the user may be duplicated, the original file resources need to be screened before being stored, and the unrepeated original file resources are stored. The repeated storage of the same file resources can be effectively reduced through the step, so that each same file resource can be stored only by one copy, the file resource is required to be referred, and the hard link is adopted, so that the resource occupation caused by file storage is effectively reduced.
Optionally, in the foregoing embodiment of the present invention, determining whether the original file resource already exists includes: processing original file resources by using a message digest algorithm to obtain a message digest; judging whether the message digest already exists, wherein the file name of each stored file resource comprises the message digest corresponding to the file resource; if so, determining that the original file resource already exists; if not, determining that the original file resource does not exist.
In order to determine whether the original file resource already exists, the content of the original file resource needs to be compared with the content of other existing file resources, which results in a large workload. And only by comparing the file names, the accuracy is reduced because the user can set the file names of the original file resources at will. Therefore, in this embodiment, each original file resource may use MD5 of the file as the file name when being stored, at this time, the file name of the original file resource is related to the content, before the original file resource is stored, it may be determined whether the same name exists, if so, it indicates that the file already exists, and the storage process may be skipped.
Optionally, in the embodiment of the present invention, before storing the original file resource, the method further includes: determining a preset position for storing original file resources; storing original file resources, comprising: and storing the original file resource at a preset position.
In this embodiment, the preset location may be a location dedicated to storing the file resource referenced by each processing module in the system, and may be different from other data storage locations.
When a user uploads or copies an original file resource to the system, the system may store the original file resource in a fixed location as a data record shared by all processing modules in the system.
Optionally, in the above embodiment of the present invention, if the number of hard links is not less than the preset value, the method further includes: outputting prompt information, wherein the prompt information is used for reminding that the original file resources cannot be deleted; and/or locking and protecting the original file resource so that the deletion operation of the original file resource cannot be executed when the deletion operation of the original file resource is received.
In this embodiment, when the number of the hard links is greater than or equal to the preset value, it indicates that there is still a module in the system that refers to the original file resource and cannot be deleted. At this time, in order to avoid the user from performing misoperation, the original file resource is deleted, which affects the normal operation of other processing modules associated with the original file resource, and the original file resource can be protected in various ways. In an optional embodiment, a prompt message may be output to notify the user that the original file resource cannot be deleted, so as to avoid a user misoperation. In another alternative embodiment, the original file resource may be locked so that the user cannot directly delete the original file resource.
Optionally, in the above embodiment of the present invention, when it is detected that a new processing module needs to refer to an original file resource, a hard link pointing to the original file resource by the new processing module is automatically created; and/or deleting the hard link pointing to the original file resource by the processing module when detecting that the reference relation of the processing module to the original file resource is released.
In this embodiment, based on the characteristics of the hard link, when a new outbound module needs to refer to an original file resource, the hard link may be created from a fixed location where the original file resource is stored, and at this time, the number of the hard links of the original file resource is increased by 1, that is, the reference count of the original file resource is increased by 1.
When a user needs to delete a processing task of a certain processing module, the file resource depended by the processing module needs to be deleted, and at the moment, only the created hard link needs to be deleted, and the original file resource does not need to be deleted.

Claims (10)
1. A processing method of file resources is characterized by comprising the following steps:
when original file resources need to be deleted, acquiring the quantity of hard links pointing to the original file resources, wherein the hard links are created between a processing module for referencing the original file resources and the original file resources;
judging whether the number of the hard links is smaller than a preset value or not;
and if so, deleting the original file resource.
2. The method of claim 1, further comprising:
receiving the uploaded original file resource;
storing the original file resource;
determining a processing module which needs to refer to the original file resource;
creating a hard link for each of the processing modules to point to the original file resource such that the processing modules reference the original file resource through the hard link.
3. The method of claim 2, wherein prior to storing the original file resource, the method further comprises:
judging whether the original file resources already exist or not;
if not, storing the original file resource;
if so, ignoring the storage operation on the original file resource.
4. The method of claim 3, wherein determining whether the original file resource already exists comprises:
processing the original file resource by using a message digest algorithm to obtain a message digest;
judging whether the message digest already exists, wherein the file name of each stored file resource comprises the message digest corresponding to the file resource;
if so, determining that the original file resource already exists;
if not, determining that the original file resource does not exist.
5. The method of claim 2, wherein prior to storing the original file resource, the method further comprises: determining a preset position for storing the original file resource;
the storing the original file resource comprises:
and storing the original file resource at the preset position.
6. The method of claim 1, wherein if the number of hard links is not less than the preset value, the method further comprises:
outputting prompt information, wherein the prompt information is used for reminding that the original file resource cannot be deleted; and/or the presence of a gas in the gas,
and locking and protecting the original file resource so that the deletion operation of the original file resource cannot be executed when the deletion operation of the original file resource is received.
7. The method of claim 1, further comprising:
when detecting that a new processing module needs to refer to the original file resource, automatically creating a hard link of the new processing module pointing to the original file resource; and/or the presence of a gas in the gas,
