FIG. 1: the invention discloses a flow chart for realizing an automation tool based on code level supporting sw _64 architecture.
Detailed Description
In order to further understand the technical scheme and the advantages of the present invention, the following detailed description of the technical scheme and the advantages thereof is provided in conjunction with the accompanying drawings.
The design concept of the invention is to realize a tool, after a source code package list is input, the relevant source codes of the architecture can be automatically filtered out, text replacement is carried out, and finally patch files corresponding to all the source code packages are output, so that the transplanting efficiency is greatly improved. Based on the assumption, the inventor conducts modeling test, gradual improvement and improvement on a large number of source code packages, and finally provides a source code package transplanting method based on an automation tool supporting sw _64 architecture at a code level.
The code level supports the automation tool of the sw _64 architecture and has two main functional points, namely an srpm software package transplanting technology and a text filtering and replacing technology based on an name command.
The srpm software package transplanting technology means that an srpm package is compiled on a target architecture and finally generates an rpm package which can run on the target architecture. The source redmat release of the srpm packet supports the mainstream architecture of the world, and the ideal situation is that the srpm source code packet is directly compiled and passed on the target architecture and runs well. When problems occur in the period, the source code packet needs to be patched according to the characteristics of a target environment and a framework, so that the smooth transplantation of the srpm source code packet is realized. The srpm software package transplanting technology is a basic skill for manufacturers who release operating system versions based on reddat release. The proficiency in this skill is mainly reflected in the transplantation of source codes related to the architecture. The transplantation of the srpm software package is also an inspection of the system compiling and running environment, and a series of processes for generating the rpm package by the srpm package and basic principles of the compiling process and the running process of the target program need to be known.
The filtering and replacing technology based on the name command text is to run the name command, the parameter is the text to be filtered and replaced, and the replaced text is output. The name command was specifically developed for an automation tool that supports the sw _64 architecture at the code level, as well as some text filtering and replacement commands in the system, say sed. The aname command is specific to the Shenwei architecture, and filters the text according to a series of judgment conditions, and replaces the text related to the alpha architecture meeting the conditions with the Shenwei architecture (sw _ 64).
Therefore, the essence of the automation tool supporting the sw _64 architecture based on the code level is a shell script, which is equivalent to a batch processing tool, the script firstly installs the srpm source code packet in the packet list, then performs text filtering and replacement on the file operation name command in the source code packet, and finally performs diff operation on the files before and after the replacement to generate the patch file. If the source code architecture is not relevant, then the generated patch file will be empty. The code level supports the automation tool of the sw _64 architecture and has a higher function, if the patch file is not empty, an srpm source code packet with one higher version can be directly generated, and the source code packet contains the newly generated patch file.
Fig. 1 is a flowchart of an implementation of an automation tool based on a code-level support sw _64 architecture, as shown in fig. 1, an implementation process of the automation tool provided by the present invention includes the following steps:
step S1: because the sw _64 architecture is a domestic CPU power-on architecture, the power-on architecture is a completely new architecture, does not belong to a mainstream architecture supported by an official, but is similar to an alpha architecture, the source code packets are required to be processed in batch at one time in the first step of the invention, and the source code packets related to the code-level support sw _64 architecture are filtered out, so that the power-on architecture is supported by the source code packets, and meanwhile, the working efficiency is greatly improved;
step S2: installing the srpm source code packet in the filtered source code packet list;
step S3: executing an aname command on the srpm source code packet in the filtered source code packet list so as to filter and replace the text;
step S4: diff operation is carried out on the files before and after replacement to generate a patch file;
step S5: if the generated patch file is not empty, directly generating a higher-version srpm source code package, wherein the higher-version srpm source code package contains the newly generated patch file, and executing step S6; if the generated patch file is empty, directly executing step S6;
step S6: adding the higher version of the srpm source code packet name as success.txt;
step S7: and ending the source code packet transplantation.
Wherein, step S2 specifically includes:
step S21: reading an srpm source code packet list line by line;
step S22: searching an srpm source code packet from a specified directory; if found, go to step S23, otherwise go to step S24;
step S23: calling an rpm command to install the srpm source code packet, and then performing step S3;
step S24: the srm source code packet name is appended with fail.txt, and step S21 is executed again.
The automatic tool based on the code level supporting sw _64 framework runs on a normalized kylin operating system (Shenwei edition), mainly comprises a shell script remove _ alpah.sh and an aname command component, and the remove _ alpha.sh can be called to the aname.
The aname command component is realized by C language design, and finally generates a target code aname which is stored under a/usr/bin directory. The aname Schwann platform belongs to the basic command component and belongs to the packet components.
The function of the aname is to filter and replace the text, the text to be filtered is transmitted to the aname as a command line parameter, and the replaced text is output.
The replacement of text is performed according to the following rules:
in the invention, the "sw _64 architecture" refers to an English identifier of a domestic CPU Shenwei architecture, and the sw _64 architecture is the Shenwei architecture.
In the invention, the "automation tool with code level supporting sw _64 architecture" refers to a Shenwei architecture tool kit, which is mainly used for transplanting a source code kit and outputting a patch file by running the tool.
In the invention, the so-called rpm is a packet management system used by a redhat release, and is convenient for installing, uninstalling, inquiring and upgrading software. The file system is constructed by an rpm packet, the source code of which is an srpm packet.
In the invention, the shell script refers to a script running on a linux system, which is similar to a batch file of a windows system, namely, a program file which is conveniently executed at one time by putting various commands into a file in advance.
In the present invention, the so-called "name" is a command component of the system base toolset that allows text filtering and replacement.
In the present invention, the so-called "diff" is a command of the system tool set, and the patch file can be generated according to the text difference by running the command.
The invention has the following beneficial effects:
1. the code level-based automated tool supporting the sw _64 architecture is essentially a shell script, and when a brand-new architecture platform is used for source code packet transplantation, the automated tool can be applied to other platforms by slightly modifying the automated tool, so that the code level-based automated tool has the advantages of strong readability, convenience in maintenance and strong transportability, and can be flexibly customized according to self requirements.
2. By running an automation tool of a code level supporting sw _64 architecture, patch files of source code packages related to the architecture can be directly output according to an input source code package list, and the efficiency of transplanting software packages can be greatly improved.
3. By using the automatic tool with the code level supporting the sw _64 architecture, in the process of transplanting the software package, only the source code related to the architecture needs to be concerned, the patch file generated by the tool is checked and verified, the script is continuously perfected after the process of returning, the reliability of the patch file can be greatly enhanced, the work content can be greatly simplified, the labor is saved, and the work efficiency is improved.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that the scope of the present invention is not limited thereto, and those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit and scope of the present invention.
