System Integration Basics

1. Assembly Integration

When some code changes, not only to ensure that its components are normal, but also to make the whole system of assembly of the individual components is normal.

2. Merge Integration

Whenever a change occurs on the same component or on a different component, you must ensure that the new version works together when the components are put together

3. Combined operation

Refers to the combination of component versions, in which the programmer uses a combination of different versions of the component when testing the component.

4. Baselines

A version of the repository that has a basic quality. A more intensive baseline means that as long as the last baseline is taken, it basically gets all the work that has been submitted at the moment.

5, merge operations (unlike merge integration, focus only on code versions merging and working properly, without concern for semantic and functional merging)

Different programmers modify the source code at the same time, and then merge the different changes to form a merged source code.

6. Components

Static link library (header file, binary file): Avoid duplicate artifacts

Dynamic link libraries, plugins: Avoid repeated loading

7. Star-Shaped mesh

Repository: Typically on a server, store historical versions

Workspaces: Each programmer's own computer, a version downloaded in the repository, and changes that have not been uploaded locally

Distributed version control System (DVCS): Git, mercurial, etc., programmers also have a local private repository on their workspaces, interacting with the public repository through a private repository

8 Multi-layer integration

The reuse of star-shaped nets

9 Typical processes of the episode

Requires programmers, testers, and integrators to

The first stage, the programmer detects their own development results, and then submits to the integration branch

In the second phase, the integration engineer ensures that everyone's changes work together to create a new version that is the baseline.

Phase III, testing
