RefDiff

English	中文

Summary

For development workload analysis, we often need to know how many commits have been created between 2 releases. This plugin offers the ability to calculate the commits of difference between 2 Ref(branch/tag), and the result will be stored back into database for further analysis.

Important Note

You need to run gitextractor before the refdiff plugin. The gitextractor plugin should create records in the refs table in your DB before this plugin can be run.

Configuration

This is a enrichment plugin based on Domain Layer data, no configuration needed

How to use

In order to trigger the enrichment, you need to insert a new task into your pipeline.

1. Make sure commits and refs are collected into your database, refs table should contain records like following:

id                                            ref_type
github:GithubRepo:384111310:refs/tags/0.3.5   TAG
github:GithubRepo:384111310:refs/tags/0.3.6   TAG
github:GithubRepo:384111310:refs/tags/0.5.0   TAG
github:GithubRepo:384111310:refs/tags/v0.0.1  TAG
github:GithubRepo:384111310:refs/tags/v0.2.0  TAG
github:GithubRepo:384111310:refs/tags/v0.3.0  TAG
github:GithubRepo:384111310:refs/tags/v0.4.0  TAG
github:GithubRepo:384111310:refs/tags/v0.6.0  TAG
github:GithubRepo:384111310:refs/tags/v0.6.1  TAG

1. And then, trigger a pipeline like following, you can also define sub tasks, calculateRefDiff will calculate commits between two ref, and creatRefBugStats will create a table to show bug list between two ref:

curl -v -XPOST http://localhost:8080/pipelines --data @- <<'JSON'
{
    "name": "test-refdiff",
    "tasks": [
        [
            {
                "plugin": "refdiff",
                "options": {
                    "repoId": "github:GithubRepo:384111310",
                    "pairs": [
                       { "newRef": "refs/tags/v0.6.0", "oldRef": "refs/tags/0.5.0" },
                       { "newRef": "refs/tags/0.5.0", "oldRef": "refs/tags/0.4.0" }
                    ],
                    "tasks": [
                        "calculateCommitsDiff",
                        "calculateIssuesDiff",
                    ]
                }
            }
        ]
    ]
}

Troubleshooting (MacOS)

Q: I got an error saying: pkg-config: exec: "pkg-config": executable file not found in $PATH

A:

1. Make sure you have pkg-config installed:

brew install pkg-config

1. Make sure your pkg config path covers the installation:

export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib:/usr/local/lib/pkgconfig
