Release VersioningSemantic Versioning semver.org

MAJOR.MINOR.PATCH[-alpha.xyz]

“Increment the:1. MAJOR version when you make incompatible

API changes,2. MINOR version when you add functionality in

a backwards-compatible manner, and3. PATCH version when you make

backwards-compatible bug fixes.”T. Preston-Werner co-founder of GitHub and CodeConf

11

Release Environment Setup

OS environment description

List of software prerequisites

Dependencies repository configuration

Build settings, e.g. Maven settings file

12

Issue Clean Up

No remaining open issues for the release

[JIRA] Transition from Resolved to Closed

[JIRA] The Fix Version attribute should include this release version

Closed issues should be documented

13

Continuous Integration Check

All test MUST pass

Or failures are understood and documented

Static code analysis – e.g. SonarQube

License analysis

Code license and copyright check – e.g. FOSSology

Prepare your source code for distribution – TripleCheck, OW2con’16

Dependency management and license compliance – Inno3, OW2con’16

14

Release Preparation – Ex: Maven Release Plugin

No uncommitted changes in the sources

No SNAPSHOT dependencies

Versions from x-SNAPSHOT to new version

Tag SCM information in the POM

Run tests against the modified POMs

Commit the modified POMs

Tag the code with release name

Bump the version in the POMs

Commit the modified POMs[Source: Maven Release Plugin Prepare Doc.] 15

Performing the Release – Ex: Maven Release Plugin

Maven dry run of release:prepare

Check pom.xml.tag and release.properties

Check GPG signatures of binaries

Maven release:prepare for real

Publication to Nexus

[JIRA] Mark version as released[Source: Apache Syncope Prepare Source for Release]

17Example: XWiki 8.3 Release Notes

Packaging for Easy Integration, Usage, Cloud Deployment

As packages in language specific package repositories: e.g. Maven Central, Eclipse Update Repository, PyPI, NPM, Ruby Gems, CPAN, ...

As installable Linux distribution packages: e.g. RPM, DEB

As Cloud templates and images: e.g. AppHub, DockerHub

18

Publication

Publication of binaries to:

Library repositories (Maven Central, …)

Mirrors (e.g. OW2, Apache, CDN, ...)

Linux distribution packaging systems

Cloud marketplaces (e.g. AppHub)

Publication of versioned documentation to:

Project site

FLOSS Manuals.net
