FIG. 1 is a schematic application scenario illustrating a method of querying inverse dependencies of software modules, according to an example embodiment.
An autopilot software project (abbreviated as autopilot project) is developed cooperatively as an example of a cooperative task. It can be appreciated that the application scenario can be extended to other collaborative development task scenarios, and also to collaborative task scenarios where multiple software modules of other types have a dependency relationship. Referring to the dashed line box in fig. 1, in the collaborative task 100 corresponding to the autopilot project, 7 software modules, namely, software modules 1 to 7, need to be organized organically, wherein the software modules 1 to 3 are third party library modules 110, the software modules 4 and 5 belong to external software modules 120 provided by suppliers, the software modules 4 are external software modules provided by suppliers a, the software modules 5 are external software modules provided by suppliers B, and the software modules 6 and 7 are internal software modules 130 self-developed by development team X.
In general, the software project of the automobile has huge scale, and the software modules involved in the application scene of high-speed sensing or low-speed parking of one automatic driving can be about 100-200. With some open-source package management tools or self-grinding package management tools, the external dependencies of each software module are typically explicitly declared in a file (e.g., a Python script file), and by looking at the script file of a certain software module, it is possible to quickly learn which software module or modules the current software module depends on.
During the development, it was found that: in the whole flow of research, development, deployment and testing of an automatic driving project, a developer can only know the direct upstream software module on which a responsible software module depends according to the information of the responsible software module, cannot comprehensively know all the upstream software modules, and cannot comprehensively know which downstream software modules the self software module depends on.
In an exemplary scenario, the third party library module 110, the external software module 120 and the internal software module 130 are responsible for different development teams, and authority setting policies exist between software module code warehouses, for example, dependency information of the third party library module 110 can only be obtained by a developer of a third party and is not open to a user, and then, for the development team X, it is impossible to obtain comprehensive dependency information between each software module in a collaborative task.
For example, in some scenarios, even if a developer can determine, from information about a plurality of software modules in a responsible group, an upstream software module and a downstream software module that have a dependency relationship in the group, for example, a developer in a development team X can obtain the dependency relationship of each of the software modules 6 and 7, and because of the authority setting policy between the software module code warehouses, the development team X may not have authority to obtain the dependency relationship information of the third party library module 110 and the external software module 120, which results in that the dependency relationship link known by the developer of one software module is not comprehensive.
In some scenarios, it is desirable to obtain software modules that are affected by one or more software modules in a collaborative task. However, the existing package management tool only contains the declaration information of the software module on which the software module depends, namely the forward dependency relationship, so that the requirement of inquiring the reverse dependency relationship of the software module cannot be met under the condition of permission setting, and the existing package management tool is relied on, so that the problems of low query efficiency and incomplete query of the reverse dependency relationship exist.
For example, referring to FIG. 1, in one exemplary scenario, a developer of a software module 4 needs to perform an integration test on the software module 4, but because the software module 4 releases a dynamic link library, it needs to perform an integration test by means of executable files of other software modules, and at this time, it needs to clearly know which software modules are affected by the integration test.
However, since software module 4 belongs to an external software module provided by vendor a and software module 5 belongs to an external software module provided by vendor B, the developer of software module 4 cannot fully learn the dependencies of software modules 1-3, 5, 6 and 7 in the collaborative task. And the quick and efficient reverse relation searching can not be performed according to the declaration information in the packet management tool corresponding to each software module. Namely, the problems of low query efficiency and incomplete query of the inverse dependency relation exist.
In other exemplary scenarios, it may also be that a developer of a certain software module performs code modification on the software module, so as to cause version upgrade of the software module, and sometimes needs to be notified to a responsible person affecting the relevant software module affected by the software module in time, that is, needs to check which software module or modules the current software module depends on. This dependency is reverse, unlike a dependency explicitly declared forward in a software module script file.
It has thus been found in research and development that there is a need for efficient and comprehensive querying of inverse relationships of one or more software modules in a collaborative task, however the related art does not take this problem into account and does not give a solution.
In view of this, the embodiments of the present disclosure provide a method, an apparatus, a device, and a medium for querying an inverse dependency relationship of a software module, by constructing a data structure for describing a forward dependency relationship between a plurality of software modules in a collaborative task, where upstream and downstream dependency relationships between each software module in the collaborative task are presented in the data structure, and performing an inverse lookup in a target data structure including a first software module, a second software module having an inverse dependency relationship with the first software module can be obtained.
Exemplary method
FIG. 2 is a flowchart illustrating a method of querying an inverse dependency of a software module, according to an example embodiment.
Referring to fig. 2, a method for querying an inverse dependency relationship of a software module according to an embodiment of the disclosure includes the following steps: s210, S220, and S230. The above method may be applied to an electronic device.
In some embodiments, the electronic device is a server that provides service support for a plurality of software modules corresponding to the collaborative task. The server may be an application server or a cloud server, including a service cluster. The server has data storage functionality or is capable of accessing and operating a database. When the server executes steps S210 to S230 to obtain a query result (for example, a second software module) corresponding to the inverse dependency relationship, the query result is sent to the terminal device corresponding to the query request.
In other embodiments, the electronic device is a terminal device having a display screen, such as a desktop computer, a notebook computer, a tablet computer, a smart phone, or the like. And a developer corresponding to one or more software modules in the plurality of software modules in the collaborative task initiates a query request to the used terminal equipment, and the terminal equipment correspondingly executes steps S210 to S230.
In step S210, a request for querying an inverse dependency relationship of a first software module, where the first software module is at least one of a plurality of software modules included in a collaborative task, is received.
Referring to fig. 1, the collaborative task 100 includes a plurality of software modules, and taking an example in which an autopilot project includes 7 software modules, the number of first software modules to query for an inverse dependency relationship may be one or more.
The above-described inverse dependency relationship is used to represent downstream software modules affected by variations in upstream software modules. The upstream software module and the downstream software module both belong to the cooperative task.
In step S220, a target data structure including the first software module is searched in a pre-built data structure, where the data structure is used to describe forward dependency relationships between the plurality of software modules in the collaborative task.
The forward dependency is used to represent the upstream software module that the downstream software module depends on.
The script file declaration information of the software module carries the description of the forward dependency. In some embodiments, the resulting data structure may be constructed from script file declaration information of the software module.
A data structure refers to a collection of data elements that have one or more relationships with each other. In the embodiments of the present disclosure, the data structure is a data form stored in the background database, and the specific form may vary, and any data structure capable of describing the forward dependency of the software module is within the scope of the present disclosure.
For example, in the vehicle field, the data structure may employ a directed acyclic graph, considering that features of the vehicle that do not allow cyclic dependencies between software modules may be mapped to acyclic features of the directed acyclic graph.
In other embodiments, the data structure may also have a corresponding presentation manner at the front end (e.g., a terminal device), so that developers of each software module of the collaborative task can know global dependency relationships between the software modules, and the developers can also conveniently perform visual understanding on downstream software modules or upstream software modules of the software modules responsible for the developers.
For example, the data structure is presented at the front end in the form of a dependency graph, which may vary in the style presented at the front end. Such as presenting software modules with circles, triangles, rectangular boxes, pentagons, hexagons, etc., presenting upstream and downstream dependencies between software modules with arrowed lines, circled lines, etc., specific presentation formats may be set and adjusted, such as: pattern style of elements, presence or absence of padding, line format, color of display elements, content representation form of display text, content style (including font color, presence or absence of tilting, bold, font size, etc.), etc.
In step S230, a reverse lookup is performed in the target data structure to obtain a second software module having an inverse dependency relationship with the first software module.
One or more second software modules having an inverse dependency relationship with the first software module are obtained by performing an inverse lookup in the target data structure, i.e. from the downstream direction of the first software module.
In the related art, each terminal device has a permission limit on information access of a non-internal software module in a collaborative task, for example, a terminal device used by a developer of the software module 4 does not have access permission on information of the software modules 1 to 3. Therefore, the developer can only know the direct upstream software module depending on the responsible software module according to the information of the responsible software module, cannot comprehensively know all the upstream software modules, and cannot comprehensively know which downstream software modules the self software module depends on.
In contrast, in the embodiment of the present disclosure, for the same collaborative task, the server side has access rights to script file declaration information of multiple software modules in the collaborative task, and the terminal device can query by the server side based on the constructed data structure to obtain a corresponding result by initiating a query request to the server side.
In the embodiment including steps S210 to S230, by constructing a data structure for describing forward dependency relationships among the plurality of software modules in the collaborative task, the data structure presents upstream and downstream dependency relationships among the software modules in the collaborative task, and performing reverse lookup in a target data structure including a first software module, a second software module having an inverse dependency relationship with the first software module can be obtained, so that query efficiency is high, query results are comprehensive, and each developer in the software modules of the collaborative task can conveniently know global dependency relationships among the software modules, and can also conveniently and comprehensively query a downstream software module or an upstream software module of the software module responsible for the developer; the participants of the collaborative task can clearly know the affected software modules under the condition that the software modules of the participants are changed, so that the participants corresponding to the affected software modules are notified correspondingly, and update compatibility test, integration test and the like among the software modules in the collaborative task are facilitated. At least, the problems of low query efficiency and incomplete query of the inverse dependency relationship existing in dependence on the existing package management tool under the condition of permission setting can be solved.
In some embodiments, the received request R 1 Is a request to query for the inverse dependency of the software module 4.
In another embodiment, the received request R 2 Is a request to query for the inverse dependency of the software module 6.
The script file declaration information of the software module carries the description of the forward dependency. In some embodiments, the resulting data structure may be constructed from script file declaration information of the software module.
In some embodiments, the data structure includes: data objects, object dependencies and relationship directives, the data objects being used to represent software modules in the collaborative task, the object dependencies being used to represent dependencies between the software modules, the relationship directives being used to represent upstream and downstream directions between two software modules involved in the object dependencies. Wherein the object dependency relationship includes at least one of: the header file contains dependencies, link dependencies to static libraries in compiled links, link dependencies to dynamic libraries in compiled links.
In the application development process, a compiler compiles a plurality of source code files into a plurality of independent unconnected target files, and then links the target files through a linker to form an executable file; a software development task often includes a plurality of software modules, and on the premise of ensuring that each software module can be compiled independently, all modules are assembled, and the process of assembling the modules is a process of compiling links.
For example, script file declaration information of the software module 1 is described as follows: the software module 1 has no external dependencies. The script file declaration information of the software module 2 is described as: the software module 2 depends on the software module 1 and the software module 3. The script file declaration information of the software module 3 is described as: the software module 3 depends on the software module 4. The script file declaration information of the software module 4 is described as follows: the software module 4 depends on the software module 9. The software module 9 is not a software module in the collaborative task 100. The script file declaration information of the software module 5 is described as follows: the software module 5 depends on the software module 2 and the software module 4. The script file declaration information of the software module 6 is described as follows: the software module 6 depends on the software module 2 and the software module 5. The script file declaration information of the software module 7 is described as follows: the software module 7 depends on the software module 1.
FIG. 3 is a schematic diagram illustrating a constructed data structure according to an example embodiment.
For example, referring to fig. 3, the server side can construct a data structure 300 according to the script file declaration information of the software modules 1 to 7 in the above example, where the data structure 300 includes 8 data objects, and in fig. 3, an oval box is used to illustrate the data objects, which are a first data object 301, a second data object 302, a third data object 303, a fourth data object 304, a fifth data object 305, a sixth data object 306, a seventh data object 307, and an eighth data object 308, respectively; the first data object 301 is used to represent software module 1, the second data object 302 is used to represent software module 2, the third data object 303 is used to represent software module 3, the second data object 304 is used to represent software module 4, the fifth data object 305 is used to represent software module 5, the second data object 306 is used to represent software module 6, the seventh data object 307 is used to represent software module 7, and the second data object 308 is used to represent software module 9.
In which, since the software module 9 is not a software module within the collaborative task, it is illustrated in fig. 3 by a dashed box, in the metadata information of the data structure 300 or in the metadata information of the software module 9, it will be explained that the software module 9 does not belong to the collaborative task 100.
Referring to FIG. 3, the data structure 300 includes object dependencies and relationship directives in addition to 8 data objects, and in FIG. 3, a connection with an arrow is used to illustrate an object dependency, where the direction of the arrow is used to illustrate a relationship director. Here, in the same line, an upstream software module is illustrated with an object pointed by an arrow, and a downstream software module is illustrated with an object away from the arrow. For example, the first dependency relationship 311 represents a dependency relationship between the software module 2 and the software module 1, where the software module 2 is a downstream software module and the software module 1 is an upstream software module.
