RefDiff

Summary

RefDiff is a plugin that performs calculation tasks and has 2 main purposes.

And the output of RefDiff is stored in the table commits_diffs, finished_commits_diffs, ref_commits.

Important Note

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

Configuration

This is an enrichment plugin based on the domain layer data, no configuration is needed.

How to use refdiff

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:1:384111310:refs/tags/0.3.5 TAG
    github:GithubRepo:1:384111310:refs/tags/0.3.6 TAG
    github:GithubRepo:1:384111310:refs/tags/0.5.0 TAG
    github:GithubRepo:1:384111310:refs/tags/v0.0.1 TAG
    github:GithubRepo:1:384111310:refs/tags/v0.2.0 TAG
    github:GithubRepo:1:384111310:refs/tags/v0.3.0 TAG
    github:GithubRepo:1:384111310:refs/tags/v0.4.0 TAG
    github:GithubRepo:1:384111310:refs/tags/v0.6.0 TAG
    github:GithubRepo:1:384111310:refs/tags/v0.6.1 TAG
  2. If you want to run calculatePrCherryPick, please configure GITHUB_PR_TITLE_PATTERN in .env, you can check the example in .env.example(we have a default value, please make sure your pattern is disclosed by single quotes '')
  3. And then, trigger a pipeline like the following format:
curl 'http://localhost:8080/pipelines' \
--header 'Content-Type: application/json' \
--data-raw '
{
"name": "test-refdiff",
"plan": [
[
{
"plugin": "refdiff",
"options": {
"repoId": "github:GithubRepo:1:384111310",
"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",
"calculatePrCherryPick",
]
}
}
]
]
}'

Or if you preferred calculating latest releases

curl 'http://localhost:8080/pipelines' \
--header 'Content-Type: application/json' \
--data-raw '
{
"name": "test-refdiff",
"plan": [
[
{
"plugin": "refdiff",
"options": {
"repoId": "github:GithubRepo:1:384111310",
"tagsPattern": "v\d+\.\d+.\d+",
"tagsLimit": 10,
"tagsOrder": "reverse semver",
"tasks": [
"calculateCommitsDiff",
"calculateIssuesDiff",
"calculatePrCherryPick",
]
}
}
]
]
}'

How to use refdiff in DORA

RefDiff can be called by the DORA plugin to support the calculation of DORA metrics. RefDiff has a subtask called 'calculateProjectDeploymentCommitsDiff'. This subtask takes the project_name from task options to calculate the commits diff between two consecutive deployments in this project. That is to say, refdiff will generate the relationship between deployed commit(s) and the deployment in which these commits get deployed.

curl 'http://localhost:8080/pipelines' \
--header 'Content-Type: application/json' \
--data-raw '
{
"name": "test-refdiff-dora",
"plan": [
[
{
"plugin": "refdiff",
"options": {
"projectName": "project_name_1",
"tasks": [
"calculateProjectDeploymentCommitsDiff"
]
}
}
]
]
}'
