Compute release candidate

[manuelstein]

Hi,

I'd like to create release candidates on feature branches, i.e. compute the next version and append an -rc.1 etc.
The current beta-release-support requires a maintained version, but I would like to have that next version automatically computed from the found version and the commit analyzer.

Example:

• latest (found) version on default 1.1.0
• create a new branch from default with a conventional commit, e.g. 'feat: great new feature'
• upon pull/merge request (or upon push), run the CI -> create release 1.2.0-rc.1

Ideally, the label rc would also be variable, so that I can concurrently work on different feature branches.

What would be a good approach to do this?

1. --maintained-version -rc
2. --maintained-version *-rc
3. --channel rc

Cheers, Manuel

I think I gave the answer already in #183.
I'm now using this gitlab script to compute next release candidates:

  script:
    - semantic-release --allow-no-changes --allow-initial-development-versions --ci-condition-opt defaultBranch="*" -f .version --dry
    - LABEL=$(echo $CI_COMMIT_BRANCH|sed 's/[^0-9a-zA-Z_-]//g'|tr '[:upper:]' '[:lower:]')
    - semantic-release --allow-no-changes --allow-initial-development-versions --maintained-version $(cat .version-unreleased)-$LABEL

Problem with above is that it repeatedly creates the first release candidate, e.g. (1.2.0-rc.1):

• The first call doesn't find the existing 1.2.0-rc.1 tag and always computes the new version 1.2.0
• The second call then always ends up creating 1.2.0-rc.1 despite it already being an existing tag

I really don't see how calculating the next release candidate (1.2.0-rc.2) could be achieved (with gitlab).

Ok, one really needs to go with the major version number only in the maintained-version (e.g. 2-alpha).

Got it working for my merge request pipelines:

  script:
    - export CI_COMMIT_BRANCH=${CI_MERGE_REQUEST_SOURCE_BRANCH_NAME}
    - LABEL=mr$CI_MERGE_REQUEST_IID
    - semantic-release --allow-no-changes --allow-initial-development-versions --force-bump-patch-version --ci-condition-opt defaultBranch="*" -f .version --dry
    - MAJOR=$(cat .version-unreleased|sed 's/\..*//')
    - semantic-release --allow-no-changes --allow-initial-development-versions --force-bump-patch-version --ci-condition-opt defaultBranch="*" --maintained-version $MAJOR-$LABEL
