Example one
Fig. 3 is a schematic flow chart of a method for updating a feature rule matching library according to an embodiment of the present invention, where the embodiment is applicable to a situation of updating a feature rule matching library, and the method may be executed by an updating apparatus of a feature rule matching library according to an embodiment of the present invention, and the apparatus may be implemented in a software/hardware manner, and may be integrated in an electronic device such as a computer or an electronic device. The method specifically comprises the following steps:

S130, determining a target sub-library to be updated in a preset time interval according to the preset time interval.
And S140, compiling the updated target sub-library, and updating the feature rule matching library according to the feature rule matching sub-library obtained by compiling.
In this embodiment, the electronic device includes a plurality of independent sub-libraries with preset capacity, where the sub-libraries are used to store information of the feature rules, and the preset capacity of each sub-library may be a capacity of 3000 feature rules. In this embodiment, the storage space for storing the feature rules is divided into a plurality of independent sub-libraries, each sub-library is used for storing the feature rules, the storage capacity of the sub-libraries is small, fast compilation can be achieved, the sub-libraries are independent from each other, and the sub-libraries can be compiled in parallel, so that the compilation time of the feature rule matching library is reduced, and the compilation instantaneity of the feature rule matching library is improved.
Receiving a feature rule processing instruction issued by the rule issuing device 20, where the feature rule processing instruction includes a feature rule processing type and feature rule information, where the feature rule processing type includes addition and deletion, and the feature rule may be a regular rule. In this embodiment, the processing logic of the feature rule is determined according to the processing type of the feature rule, and the processing logic corresponding to different processing types of the feature rule is different. In this embodiment, the target sub-library is processed according to the feature rule processing instruction and the corresponding processing logic, that is, the feature rule is added to the target sub-library or the corresponding feature rule is deleted from the target sub-library. Correspondingly, because the characteristic rules stored in other sub-libraries are not changed, when the characteristic rule matching library is updated, the updated target sub-library can be compiled only, so that the characteristic rule matching library can be updated, all the sub-libraries do not need to be compiled, the compiling process of the characteristic rule matching library is simplified, the compiling efficiency of the characteristic rule matching library is improved, and the compiling real-time performance of the characteristic rule matching library is improved.
When the feature rule processing type is increased, optionally, determining a target sub-library according to the feature rule processing instruction, and updating the target sub-library based on the feature rule processing type and the feature rule information includes: determining currently available sub-libraries, wherein any sub-library in the currently available sub-libraries is determined as a target sub-library; and adding the characteristic string in the characteristic rule information into the target sub-library. And the current available sub-library is a sub-library which has residual capacity and can store the newly added characteristic rules. In this embodiment, any currently available sub-library may be determined as a target sub-library, and a feature string of a feature rule is added to the target sub-library, where when the feature rule is a regular rule, the feature string of the feature rule is a regular expression.
Optionally, an available sub library list is set in the electronic device, where the available sub library list includes identification information of a currently available sub library, and accordingly, determining the currently available sub library includes: reading the identification information of the currently available sub-library from the list of available sub-libraries, and determining the currently available sub-library based on the identification information of the currently available sub-library, wherein the identification information of the available sub-library may be the number of the sub-library. After receiving the characteristic rule processing instruction, when the characteristic rule processing type is increased, reading the identification information of the current available sub-library from the available sub-library list, when the identification information can be read, determining a target sub-library according to the read identification information, when the read identification information is empty, determining that the current available sub-library does not exist, creating a new sub-library, determining the newly-built sub-library as the target sub-library, and correspondingly, adding the identification information of the newly-built sub-library into the available sub-library list.
Optionally, after the feature string in the feature rule information is added to the target sub library, determining a remaining capacity of the target sub library, when the remaining capacity of the target sub library is 0, determining that the target sub library is full, removing the identification information of the target sub library from the available sub library list, when the remaining capacity of the target sub library is greater than 0, indicating that the target sub library is still the available sub library, maintaining the available sub library list, and not processing the available sub library list.
It should be noted that, because the feature rule information includes not only the feature string, in order to ensure that other information of the feature is not lost, a rule array is set in the electronic device, and the rule number is used for storing structured feature rule data. Optionally, after receiving the feature rule processing instruction, when the feature rule processing type is increased, the rule array is searched by using the feature rule ID of the feature rule information as an index. When the rule array has the feature rule identical to the feature rule ID, error prompt information is generated, when the rule array does not have the feature rule identical to the feature rule ID, a structured feature object is generated according to the feature rule information, and the feature object is stored in the corresponding position of the feature rule ID in the rule array. Accordingly, after the currently available sub-library is determined, the feature string in the feature rule information is added to the target sub-library.
When the feature rule processing type is deletion, optionally, determining a target sub-library according to the feature rule processing instruction, and updating the target sub-library based on the feature rule processing type and the feature rule information includes: inquiring in each sub-library based on the identification information in the characteristic rule information, and determining the sub-library in which the characteristic rule information to be deleted is positioned as a target sub-library; and deleting the characteristic string in the characteristic rule information in the target sub-library. In each sub-library, the stored feature string of the feature rule carries identification information (for example, the feature rule ID), and matching can be performed according to the identification information to determine a target sub-library where the feature rule information to be deleted is located. The mapping relationship between the feature rule identifier and the sub-library may also be set, and the sub-library corresponding to the feature rule identifier, that is, the target sub-library for storing the feature rule information to be deleted, may be determined based on the mapping relationship. And deleting the feature string in the feature rule processing instruction from the target sub-library, and correspondingly, removing the mapping between the feature rule identification of the feature string and the sub-library from the mapping relation.
It should be noted that, with the feature rule ID of the feature rule information as an index, a rule array is searched, a corresponding feature object is deleted from the feature array, and the position of the feature rule ID in the index is set to be null.
On the basis of the embodiment, the target sub-library to be updated is determined according to the preset time interval, and the target sub-library to be updated in the preset time interval is input into the rule compiler for compiling. Exemplarily, referring to fig. 4, fig. 4 is a compilation schematic diagram of a Hyperscan library provided by an embodiment of the present invention, where an electronic device includes three sub-libraries, a sub-library 1, a sub-library 2, and a sub-library 3, which are used for storing a regular expression, the sub-library 1 and the sub-library 3 are updated at a preset time interval, the sub-library 1 and the sub-library 3 are input to a Hyperscan compiler, a feature rule matching sub-library is obtained through compilation, an original feature rule matching library is updated based on the feature rule matching sub-library to obtain a new feature rule matching library, and compared to fig. 1, when a feature rule is updated, all feature rules are recompiled, so that the number of feature rules to be compiled is reduced, and meanwhile, multiple sub-libraries can be compiled in parallel, so that compiling efficiency and compiling real-time are further provided.
Optionally, an updated sub-library list is set, and after the target sub-library is updated based on the feature rule processing type and the feature rule information, the identification information of the target sub-library is added to the updated sub-library list; correspondingly, the determining the target sub-library updated within the preset time interval includes: and determining an updated target sub-library based on the identification information in the updated sub-library list, namely determining the target sub-library corresponding to the identification information in the updated sub-library list as the updated target sub-library.
Inputting the updated target sub-library into the rule compiler to obtain a new feature rule matching sub-library, and correspondingly updating the feature rule matching library according to the compiled feature rule matching sub-library, wherein the step of updating the feature rule matching library can be that the original feature rule matching sub-library corresponding to the new feature rule matching sub-library in the original feature rule matching library is replaced based on the new feature rule matching sub-library by traversing the original feature rule matching library to obtain the new feature rule matching library. It should be noted that the original feature rule matching library is not an original feature rule matching library in use, but an original feature rule matching library stored in the electronic device.
It should be noted that, in order to avoid frequent compiling of the target sub-library, a preset time interval for performing caching is set, where the preset time interval is of the order of ms, and may be, for example, 1ms or 10ms, the preset time interval may be determined according to the real-time requirement of the feature rule matching library, and the higher the real-time requirement is, the smaller the preset time interval is.
On the basis of the above embodiment, after the updated target sub library is compiled, the updated sub library list is emptied, and the identification information of the updated target sub library in the next preset time interval is added to the empty updated sub library list.
On the basis of the above embodiment, after compiling the updated target sub-library, the method further includes: emptying the available sub-library list; and traversing each sub-library, determining the sub-library with the residual capacity larger than the preset value as a current available sub-library, and generating a new available sub-library list according to the identification information of the current available sub-library. In this embodiment, only the sub-library with the remaining capacity greater than the preset value is determined as the current available sub-library, and therefore, when the sub-library with the smaller remaining capacity is used as the available sub-library, the number of the updated feature rules of the available sub-library is smaller, which correspondingly increases the number of the updated sub-libraries and affects the compiling efficiency.
According to the technical scheme, the space for storing the feature rules is divided into the plurality of independent sub-libraries, the target sub-library is updated according to the feature rule processing instructions, and only the updated target sub-library is compiled, so that the feature rule matching library is updated, the sub-libraries are small in capacity and high in compiling speed, the sub-libraries are independent from one another and can be compiled in parallel, compiling time is shortened, compiling efficiency of the feature rule matching library is improved, and compiling real-time performance of the feature rule matching library is improved. Meanwhile, the updated target sub-libraries are compiled based on the preset time interval, so that frequent updating of each sub-library in the characteristic rule processing process is prevented.
On the basis of the above embodiment, after updating the feature rule matching library according to the compiled feature rule matching sub-library, the method further includes: acquiring a read lock, wherein the read lock is used for refusing access to an original feature rule matching library; replacing the original feature rule matching library based on the updated feature rule matching library; releasing the read lock.
It should be noted that the new feature rule matching library obtained in the above embodiment cannot be used, and through a lock reading operation, access to the original feature rule matching library is denied, and based on the feature rule matching library after being updated calling a feature library matching interface for matching, replacement of the original feature rule matching library is realized, a lock reading is released, and access to the updated feature rule matching library is allowed. In the embodiment, the original characteristic rule matching library is replaced based on the matching interface in the lock reading state, so that the original characteristic rule matching library used in the control system is rapidly updated.
