[0002] Currently, in database projects, it is common to involve other third-party library files. Introducing various third-party library files in the project can enable the database to support the functions of the corresponding libraries, improving the development progress and the reliability of the database.

[0003] However, since the implementations of third-party libraries are generally different, it is necessary to adjust them after introducing the third-party libraries to adapt to the database project. This will involve a large number of modifications when introducing multiple third-party libraries, and the management of each third-party library is also very complex. However, when multiple third-party libraries need to be introduced simultaneously, the problems existing in each third-party library may be different. In this case, it is often difficult to maintain and reuse the code when calling third-party libraries. Moreover, as the number of third-party libraries increases, the management of third-party libraries will become more complex and difficult.

[0030] In order to enable those skilled in the art to better understand the solutions of the present invention, the following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. It should be understood that the various steps recorded in the method embodiments of the present invention can be executed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present invention is not limited in this regard.

[0035] The handling of exception error reports by different third-party libraries is usually different. After being called in a database project, the error information may not be returned in the expected form; the memory management methods of different third-party libraries also have differences, and there may even be situations that cause memory leaks; at the same time, third-party libraries may have thread safety issues, and thread safety issues in a database may lead to very serious consequences. Therefore, third-party libraries with thread safety hazards can hardly be used in a database.

[0036] After introducing third-party library files into the current database project, for different problems, it is usually necessary to handle them separately. This handling method cannot effectively manage all third-party libraries, and it is difficult to trace the source of problems.

[0037] Embodiment 1

[0038] Figure 1The flowchart shows a method for managing third-party libraries provided in the first embodiment of the present invention. This method is applicable to the situation where a database calls a third-party library and encapsulates the third-party library. This method can be executed by a third-party library management device, which can be implemented by software and / or hardware and is generally integrated into an electronic device. In this embodiment, an interface function layer in a third-party library adaptation layer is provided on the electronic device.

[0039] As Figure 1 shown, a method for managing third-party libraries provided in the first embodiment of the present invention includes the following steps:

[0040] S110. Obtain one or more third-party libraries to be loaded by the database.

[0041] Among them, the database can be a relational database, a non-relational database, or other databases. A third-party library can be a module with specific functions released by other third-party institutions.

[0042] In this embodiment, one or more third-party libraries required by the database can be obtained.

[0043] S120. Analyze each of the third-party libraries separately to determine the problems existing in each of the third-party libraries when adapting to the database.

[0044] Among them, the problems existing in different third-party libraries may be the same or different. The problems existing in the third-party libraries in this embodiment can be classified into the following types: thread safety problems, memory management problems, and exception reporting problems. Analyzing the third-party library can specifically be analyzing the functions in the third-party library, and the specific analysis method can be manual or automatic. For example, when determining whether a third-party library has thread safety problems, the use of global variables, pipes, shared variables, etc. in the third-party library can be analyzed.

[0045] In this embodiment, the third-party libraries can be analyzed to determine the problems that may exist in the third-party libraries when adapting to the database. Exemplarily, taking the Topology Relation Operation Utility Library (Geometry Engine - Open Source, GEOS), proj library, and Light-weight geometry (lwgeom) library, which are often used to develop functions related to geometric graphics and geographic data, as examples, the functions of the geos library have thread safety problems, and the error reporting mechanism needs to be processed separately; while the proj library and the geos library have the same thread safety problems, but the error reporting mechanism is different from that of the geos library; the lwgeom library mainly has memory management problems and exception reporting problems.

[0046] S130. Encapsulate the functions in each of the third - party libraries according to the problems corresponding to each third - party library to complete the loading of all third - party libraries.

[0047] Among them, encapsulation can be a process of defining a class, encapsulating data and related operations inside the class, and providing public interfaces to the outside to access and operate on the data. Through encapsulation, information hiding can be achieved, and the maintainability of the code can be improved.

[0048] In this embodiment, for the problems existing in the third - party libraries, different methods can be used to encapsulate the functions in the third - party libraries, so as to obtain the encapsulated third - party libraries and complete the loading of all third - party libraries.

[0049] A method for managing third - party libraries provided in Embodiment 1 of the present invention includes: obtaining one or more third - party libraries to be loaded in a database; analyzing each of the third - party libraries separately to determine the problems existing in each of the third - party libraries when adapting to the database; encapsulating the functions in each of the third - party libraries according to the problems corresponding to each third - party library to complete the loading of all third - party libraries. This method can uniformly manage third - party libraries by analyzing the problems existing in third - party libraries and encapsulating the third - party libraries according to the problems, and solves the problem of difficult management of third - party libraries in the prior art.

[0050] Based on the above - mentioned embodiment, a variant embodiment of the above - mentioned embodiment is proposed. Here, it should be noted that for the sake of brief description, only the differences from the above - mentioned embodiment are described in the variant embodiment.

[0051] In one embodiment, when the problems existing in the third - party library include thread - safety problems, encapsulating the functions in the third - party library includes: determining whether the third - party library provides a thread - local storage function; if so, directly encapsulating the functions in the third - party library, otherwise encapsulating the functions in the third - party library through a lock mechanism.

[0052] Among them, the thread - safety problem may refer to the problem that when multiple threads access shared resources concurrently, the correctness and consistency of the program cannot be guaranteed. When multiple threads operate on the same data simultaneously, without appropriate control measures, data inconsistency or unpredictable behavior may occur. Thread - Local Storage (TLS) is a mechanism set for the consideration that each thread in a multi - threaded process itself needs to maintain some states. Each thread in a given multi - threaded process can use this method to allocate a location for storing thread - specific data. The lock mechanism is a method to ensure data consistency and thread safety in multi - threaded programming. The lock mechanism can make it so that at a certain moment, only one thread can access the shared resource or the critical - section code. Other threads must wait for the release of the lock before they can compete for the lock again.

[0053] In this embodiment, when there are thread safety issues in the third-party library, it can be determined whether the third-party library provides the function of thread-local storage. If so, it means that the third-party library can solve the thread safety problem through the dynamic TLS method, and then the functions in the third-party library can be directly encapsulated; otherwise, mechanisms such as lock mechanisms or mutexes need to be added when encapsulating the functions.

[0054] In one embodiment, when the problems existing in the third-party library include memory management problems, encapsulating the functions in the third-party library includes: determining whether the third-party library provides a method for setting a callback function; if so, encapsulating the memory processing functions in the third-party library through the callback function; if not, encapsulating the functions in the third-party library through overloaded functions.

[0055] Among them, memory management problems can refer to problems such as the inability to effectively allocate, use, and release memory. A callback function can refer to a function that is passed as a parameter to another function and is called and executed when a specific event occurs or a condition is met. A memory processing function can be a function library for managing memory resources.

[0056] In this embodiment, when there are memory management problems in the third-party library, it can be determined whether the third-party library provides a method for setting a callback function. If so, the memory processing functions in the third-party library can be encapsulated through the callback function; if not, the functions in the third-party library need to be encapsulated through overloaded functions. For example, for a third-party library with C++ as the main language, the way of overloaded functions can be to overload the new and delete methods in each base class.

[0057] In one embodiment, encapsulating the memory processing functions in the third-party library through the callback function includes: finding the pointers of the memory processing functions in the third-party library and the pointers of the memory processing functions in the database through the callback function; replacing the memory processing functions in the third-party library with the memory processing functions in the database through the pointers of the memory processing functions in the third-party library and the pointers of the memory processing functions in the database.

[0058] Among them, a pointer can refer to a memory address.

[0059] In this embodiment, when the third-party library sets a memory processing function, it means that it allows the caller to pass in its own memory processing function. Then, the pointers of the memory processing functions in the third-party library and the pointers of the memory processing functions in the database can be found through the callback function. Through their respective pointers, the memory processing functions in the third-party library can be replaced with the memory processing functions in the database.

[0060] In one embodiment, when the problems existing in the third-party library include abnormal error reporting problems, encapsulating the functions in the third-party library includes: determining whether the third-party library provides an exception handling function; if so, directly encapsulating the functions in the third-party library, otherwise encapsulating the functions in the third-party library by setting a jump mechanism.

[0061] Among them, the abnormal error reporting problem can be a problem related to error handling during program operation. The jump mechanism can be a method that enables a program to jump from one function to another function according to conditions or direct instructions. The exception handling function can be a specific code structure used to capture and handle exception situations that occur during program operation.

[0062] In this embodiment, when there are abnormal error reporting problems in the third-party library, it can be determined whether the third-party library provides an exception handling function. If so, the functions in the third-party library can be directly encapsulated. Otherwise, a jump mechanism needs to be set to solve the abnormal error reporting problems existing in the third-party library.

[0063] In one embodiment, encapsulating the functions in the third-party library by setting a jump mechanism includes: setting an error reporting function for the third-party library; setting a jump mechanism for the function at the error reporting position in the third-party library, and the jump mechanism is to jump to the error reporting function when an error occurs.

[0064] Among them, the error reporting function can be a function used for error reporting. The process of the jump mechanism is to jump to the error reporting function when an error occurs.

[0065] In this embodiment, a jump mechanism can be set for a third-party library without an exception handling function, that is, an error reporting function is set for the third-party library, and a jump mechanism is set for the function at the error reporting position in the third-party library.

[0066] Exemplarily, Figure 2 is a schematic flowchart of a method for managing a third-party library provided by an embodiment of the present invention, as Figure 2As shown, it is possible to determine whether there are thread safety issues, memory management issues, and exception reporting issues in the third-party library. Taking the geos library, proj library, and lwgeom library as examples, after adopting the method of unified management of the third-party library adaptation layer, after introducing the geos library into the adaptation layer, for thread safety issues, the thread-safe interfaces provided by the geos library can be used; for exception reporting issues, a callback function can be set for exception reporting. After introducing the proj library, the same method can be used to handle thread safety issues. For exception reporting issues, since the proj library provides functions specifically for handling error messages, the error messages can be directly called to obtain and then report exceptions. After introducing the lwgeom library, the dynamic tls mechanism can be used to solve thread safety issues, and the callback function method can be used to handle memory issues.

[0067] Embodiment 2

[0068] Figure 3 FIG. is a schematic structural diagram of a third-party library adaptation system provided by Embodiment 2 of the present invention. For details not described in this embodiment, please refer to Embodiment 1. As Figure 3 shown, a third-party library adaptation system provided by Embodiment 2 of the present invention includes an external third-party library function layer 10 and a third-party library adaptation layer 200 in the database management layer 20. The third-party library adaptation layer 200 includes an interface function layer 201 and a functional function layer 202. The interface function layer 201 is respectively connected to the functional function layer 202 and the external third-party library function layer 10;

[0069] The interface function layer 201 is used to encapsulate the functions of the third-party library in the external third-party library function layer 10;

[0070] The functional function layer 202 is used to call the encapsulated third-party library through the security interface of the interface function layer 201 to use the functions of the third-party library.

[0071] Among them, the external third-party library function layer 10 may include different third-party libraries. The database management layer 20 may be a module for managing the database, and the database management layer 20 may be a Database Management System (DBMS). The third-party library adaptation layer 200 may be a module for processing the third-party library. The interface function layer 201 may be a module for processing and encapsulating the third-party library, and the functional function layer 202 may be a module for calling the functions of the third-party library.

[0072] In this embodiment, a third-party library adaptation layer can be added to the database project, and the third-party libraries are uniformly managed through the third-party library adaptation layer. The connection function layer 201 can obtain the third-party libraries in the external third-party library function layer 10, encapsulate the functions of the third-party libraries, and the functional function layer 202 can call the encapsulated third-party libraries through the security interface of the connection function layer 201, so as to use the functions of the third-party libraries.

[0073] Exemplarily, Figure 4 FIG. is a schematic structural diagram of a third-party library adaptation system provided by an embodiment of the present invention. As Figure 4 shown, the external third-party library function layer may include multiple third-party libraries, such as GEOS, Proj, etc. The functional function layer may also be connected to the internal functions. When the corresponding functions need to be executed, the functional function layer may call the internal functions to execute the internal functions of the database, and execute the functions of the third-party libraries by calling the connection function layer.

[0074] In this embodiment, by adopting a vertical layered structure, only the functional function layer is provided for the database project to use. The connection function layer encapsulates the third-party library functions, and the functional function layer indirectly calls the third-party libraries by calling the security interface provided by the connection function layer, which can solve the problems such as thread safety, memory management, and error reporting and exceptions existing when directly calling the third-party library functions.

[0075] A third-party library adaptation system provided by Embodiment 2 of the present invention includes an external third-party library function layer and a third-party library adaptation layer in the database management layer. The third-party library adaptation layer includes a connection function layer and a functional function layer. The connection function layer is respectively connected to the functional function layer and the external third-party library function layer; the connection function layer is used to encapsulate the functions of the third-party libraries in the external third-party library function layer; the functional function layer is used to call the encapsulated third-party libraries through the security interface of the connection function layer to use the functions of the third-party libraries. By separately solving the problems of each third-party library and uniformly managing them in the third-party library adaptation layer, the management difficulty and maintenance cost of the third-party libraries are reduced, and it is easy to introduce new third-party libraries and update and modify the existing third-party libraries, solving the problem of difficult management of third-party libraries in the prior art.
