The SaltStack team follows a git policy to maintain stability and consistency with the repository.
The git policy has been developed to encourage contributions and make contributing to Salt as easy as possible. Code contributors to SaltStack projects DO NOT NEED TO READ THIS DOCUMENT, because all contributions come into SaltStack via a single gateway to make it as easy as possible for contributors to give us code.
The primary rule of git management in SaltStack is to make life easy on contributors and developers to send in code. Simplicity is always a goal!
All new SaltStack code should be submitted against either the
or a point release branch, depending on the nature of the submission. Please see
the Which Salt Branch? section of Salt's
Contributing documentation or the Release Branching
section below for more information.
SaltStack maintains two types of releases,
Feature Releases and
Point Releases (also commonly referred to as
Bugfix Releases. A
feature release is managed by incrementing the first or second release point
number, so 2015.5.5 -> 2015.8.0 signifies a feature release
and 2015.8.0 -> 2015.8.1 signifies a point release.
Each feature release is maintained in a dedicated git branch derived from the last applicable release commit on develop. All file changes relevant to the feature release will be completed in the develop branch prior to the creation of the feature release branch. The feature release branch will be named after the relevant numbers to the feature release, which constitute the first two numbers. This means that the release branch for the 2015.8.0 series is named 2015.8.
A feature release branch is created with the following command:
# git checkout -b 2015.8 # From the develop branch # git push origin 2015.8
Each point release is derived from its parent release branch. Constructing point releases is a critical aspect of Salt development and is managed by members of the core development team. Point releases comprise bug and security fixes. Bug fixes can be made against a point release branch in one of two ways: the bug fix can be submitted directly against the point release branch, or an attempt can be made to back-port the fix to the point release branch.
Bug fixes should be made against the earliest supported release branch on which the bug is present. The Salt development team regularly merges older point release branches forward into newer point release branches. That way, the bug fixes that are submitted to older release branches can cascade up through all related release branches.
Determining when a point release is going to be made is up to the project leader (Thomas Hatch). Generally point releases are made every 2-4 weeks or if there is a security fix they can be made sooner.
The point release is only designated by tagging the commit on the release branch with a release number using the existing convention (version 2015.8.1 is tagged with v2015.8.1). From the tag point a new source tarball is generated and published to PyPI, and a release announcement is made.
