# Release Workflow

Print this document.

## Issues

Check the following issue filters:

* [Pending backports](https://dev.icinga.org/projects/i2/issues?query_id=41)
* [Invalid target version](https://dev.icinga.org/projects/i2/issues?query_id=55)

## Backport Commits

    $ git checkout master
    $ ./pick.py -V 2.4.7

The script creates a new branch 'auto-merged-2.4.7' which is based on the
current support branch. It then merges all commits from the 'master' branch which
reference a ticket for the version that was specified.

If there are any merge commits you will need to manually fix them and continue the
rebase until no commits are left:

    $ git rebase --continue

After finishing the rebase the branch needs to be merged into the support branch:

    $ git checkout support/2.4
    $ git merge --ff-only auto-merged-2.4.7

## Authors

Update the [.mailmap](.mailmap) and [AUTHORS](AUTHORS) files:

    $ git checkout master
    $ git log --use-mailmap | grep ^Author: | cut -f2- -d' ' | sort | uniq > AUTHORS

## Version

Update the version number in the following files:

* [icinga2.spec]: Version: (.*)
* [icinga2.nuspec]: <version>(.*)</version>
* [tools/chocolateyInstall.ps1]: Icinga2-v(.*)-{x86,x86_64}.msi

## Changelog

Update the [ChangeLog](ChangeLog), [doc/1-about.md](doc/1-about.md) files using
the changelog.py script. Also generate HTML for the wordpress release announcement.

Changelog:

    $ ./changelog.py -V 2.4.7

Docs:

    $ ./changelog.py -V 2.4.7 -l

Wordpress:

    $ ./changelog.py -V 2.4.7 -H -l

## Git Tag

Commit these changes to the "master" branch:

    $ git commit -v -a -m "Release version <VERSION>"

For minor releases: Cherry-pick this commit into the "support" branch.

Create a signed tag (tags/v<VERSION>) on the "master" branch (for major
releases) or the "support" branch (for minor releases).

GB:

    $ git tag -u EE8E0720 -m "Version <VERSION>" v<VERSION>

MF:

    $ git tag -u D14A1F16 -m "Version <VERSION>" v<VERSION>

Push the tag.

    $ git push --tags

For major releases: Create a new "support" branch:

    $ git checkout master
    $ git checkout -b support/2.4
    $ git push -u origin support/2.4

For minor releases: Push the support branch, cherry-pick the release commit
into master and merge the support branch:

    $ git push -u origin support/2.4
    $ git checkout master
    $ git cherry-pick support/2.4
    $ git merge --strategy=ours support/2.4
    $ git push origin master
