MXCuBE Versioning Guide step-by-step

Initializing the demo repo:

  • We are in version 0.1.0 with tag.
  • Create branches master, release and develop

Prepare tag for develop new version 0.2.0:

  • Checkout develop

  • bump version as

    bumpversion minor -m '[skip ci] new version'

    This creates the tag 0.2.0.dev0 and the message header deactivates the execution of any GitHub CI

  • Push develop to origin as:

    git push origin develop --tags

Working on the development branch:

  • From develop, start a feature branch:

    git checkout -b feat-01

  • Commit your changes and push your branch to origin.

    git push origin feat-01

  • Create the PR from feat-01 to develop using the github interface.

  • Accepting the PR will merge feat-01 branch into develop (1 commit).

  • The GitHub Action will use an extra commit to bump and push the new version tag into 'develop', in this example would be 0.2.0.dev1.

  • Once the GitHub Action is finished, you can pull the repo again and update your develop branch and keep working:

    git fetch origin
git checkout develop
git pull origin develop

Release Candidate procedure:

  • Checkout release branch and merge develop into it.

    git checkout release
git merge --no-ff develop

  • Bump the version to release as follows:

    bumpversion release --no-commit

    This will bump the version creating a new tag as x.y.z.devN -> x.y.z.rc0

  • Modify the commit message by adding the [skip ci] on the header, to avoid bumping the version on commit.

  • Push release branch to origin.

    git push origin release --tags

  • At this stage, release branch is ready for test. See the following section to work on the release branch.

  • Checkout develop branch and update the version to restart the development of a new potential release branch.

    git checkout develop
bumpversion minor -m '[skip ci] Update minor version'

    This will bump the version as x.y.z.devN -> x.y+1.0.dev0. Then you can develop to origin.

    git push origin develop --tags

    After these actions, both develop and release branches are ready to keep working.

Working on the release branch

Any change on the release branch can be committed and pushed directly to origin/release or can be integrated via PR (to be decided). Both actions will automatically bump the release candidate version as x.y.z.rcN -> x.y.z.rcN+1.

Bring the changes to develop branch

The changes committed into the release branch need to be brought back into develop branch MANUALLY, in order to solve the conflicts regarding the version number. This conflict will be solved by resume the develop branch versioning, as if it was a standard feature branch from develop. We cannot use a PR in this merge from release to develop, cause the resolution of the conflicts would create a merge from develop to release, cause the CI cannot be skipped in the github IDE interface. So:

git checkout develop
git merge --no-ff release

At this point you need to solve the conflicts regarding the versioning by resuming the develop version. Once fixed, commit your changes to develop which will trigger the version bumping automatically.

git push origin develop

Finally, update your local develop branch to keep developing on:

git pull origin develop

Final Release procedure

  • Once accepted the release candidate branch, Checkout the master branch and merge the releasebranch.

    git checkout master
git merge --no-ff release

  • Bump the version to release as follows:

    bumpversion release --no-commit

    This will bump the version creating a new tag as x.y.z.rcN -> x.y.z

  • Modify the commit message by adding the [skip ci] on the header, to avoid bumping the version on commit.

  • Push master branch to origin.

    git push origin master --tags

  • At this stage, master branch is ready for test.

    (Any change on the master branch MUST be committed directly into it and merged back into develop via PR. This PR will have conflicts regarding the version number, which MUST follow the develop branch versioning, as if it would be a feature branch.)

Working on the master branch (hot fix)

Any change on the release branch can be committed and pushed directly to origin/master or can be integrated via PR (to be decided). Both actions will automatically bump the master version as x.y.z -> x.y.z+1.

Bring the changes to develop branch

The changes committed into the master branch need to be brought back into develop branch MANUALLY, in order to solve the conflicts regarding the version number. This conflict will be solved by resume the develop branch versioning, as if it was a standard feature branch from develop. We cannot use a PR in this merge from master to develop, cause the resolution of the conflicts would create a merge from develop to master, cause the CI cannot be skipped in the github IDE interface. So:

git checkout develop
git merge --no-ff master

At this point you need to solve the conflicts regarding the versioning by resuming the develop version. Once fixed, commit your changes to develop which will trigger the version bumping automatically.

git push origin develop

Finally, update your local develop branch to keep developing on:

git pull origin develop
