软件工程configurationmanagement

软件工程configurationmanagement is 确保软件产品 integrity, consistency and 可追溯性 一系列活动. 它throughmanagement软件 变更 and version, 确保Software Development过程 可控性 and 可预测性. 本章将介绍configurationmanagement basicconcepts, version控制system, configurationmanagement过程, tool and best practices, helping您Understandsuch as何 in Software Development过程in has 效实施configurationmanagement.

1. configurationmanagement basicconcepts

1.1 configurationmanagement 定义

configurationmanagement (Configuration managementment, CM) is asystem工程method, 用于 in 整个软件生命周期in识别, 组织 and 控制 for 软件产品 modify. configurationmanagement 主要目标 is :

  • 标识软件 configuration项及其version
  • 控制 for configuration项 modify
  • 记录 and 报告configuration项 status and 变更
  • 确保软件产品 integrity and consistency
  • support软件 test, deployment and maintenance

1.2 configuration项

configuration项 (Configuration Item, CI) is 指 in Software Development过程in被识别 and management , 需要forversion控制 任何可deliverable. configuration项including:

  • codefile: sourcescode, 头file, 脚本etc.
  • documentation: requirementsdocumentation, designdocumentation, testdocumentationetc.
  • data: testdata, configurationdata, datalibrary脚本etc.
  • tool: 编译tool, testtool, deploymenttooletc.
  • environment: Developmentenvironment, testenvironment, produceenvironment configuration

1.3 configuration基线

configuration基线 (Configuration Baseline) is 指 in specific时间点 on , 经过正式review and 批准 一组configuration项 collection. configuration基线serving as after 续变更 基准, 具 has 以 under 特点:

  • 基线 is stable , 只 has through正式 变更控制流程才能modify
  • 基线 for Software Development and testproviding了明确 reference点
  • 基线 has 助于追踪软件 演化过程
  • 基线support软件 parallelDevelopment and release

configurationmanagement important 性

configurationmanagement important 性体现 in 以 under 几个方面:

  • submitting (Commit) : 保存code变更 operation
  • branch (Branch) : code 独立Development线
  • merge (Merge) : 将一个branch 变更merge to 另一个branch
  • 远程 (Remote) : network on code仓libraryreplica
  • clone (Clone) : copy远程仓library to 本地
  • push (Push) : 将本地变更push to 远程仓library
  • pull (Pull) : from 远程仓library获取变更并merge to 本地
  • checkout (Checkout) : 切换 to 不同 branch or version
2.3.2 Git basicoperation
# 初始化仓library $ git init # clone仓library $ git clone https://github.com/user/repo.git # 添加file to stage区 $ git add file.txt # submitting变更 $ git submitting -m "Commit message" # 查看status $ git status # 查看log $ git log # creationbranch $ git branch feature-branch # 切换branch $ git checkout feature-branch # mergebranch $ git checkout main $ git merge feature-branch # push变更 $ git push origin main # pull变更 $ git pull origin main
