braumeister is a release-candidate preparation tool for git and JIRA users. Given a fix-version, it gathers git branches mentioned in JIRA issues targetting this fix-version and merges them in a release-candidate branch.

Installation

The braumeister requires at least Python 3.5

Install with:

pip3 install braumeister

Configuration

You can initialize the braumeister inside the root directory of a git repository like this:

braumeister init

The braumeister will create a .braumeister configuration file in the current directory. The configuration may look like this:

[general]
verbose = false

[git]
main_branch_name = main

[jira]
url = https://your-domain.atlassian.net
username = my-user
password = my-api-token
destination_transition = Merged
branch_custom_field_id = customfield_5711

Section	key	default value	description
general	verbose	false	Verbose output
git	main_branch_name	master	Define the main branch name for your git project
jira	url	None	JIRA Base URL
jira	username	None	A JIRA User
jira	password	None	The password for the user
jira	destination_transition	None	Workflow Transition name for the ticket after merging, if executed with -u
jira	branch_custom_field_id	None	The JIRA Custom Field where we should read the branch from

We'll be looking for a configuration file at the following places

[CURRENT-DIRECTORY]/.braumeister
~/.braumeister

It's recommended to add the following files to your .gitignore

.braumeister
release_state.json

JIRA Configuration

Custom Field für Branch anlegen

In JIRA, press gg (or .) to open the "Quick Actions" > Type Custom Fields > Add custom field > Text field (single line) > Next

Name: Branch
Description: git Branch

In the next screen, you need to assign the created field to one or more screens. The branch_custom_field_id is customfield_[ID] whereas the ID is the number in the URL behind the customFieldId=. e.g.:

https://jira.dev/secure/admin/ConfigureCustomField!default.jspa?customFieldId=57111

Here, the JIRA Custom Field Id is 5711, so the braumeister configuration for branch_custom_field_id would be customfield_5711.

Description

The braumeister requests all issues from JIRA with the given release name as Fix Version. In theses tickets, we'll search for the configured custom field (eg Branch) containing the git branch. The release branch will be created like this:

release/[cleaned_release_name]_RC_[LATEST_RC + 1]

If the braumeister discovered a branch with the same name, we'll increase the RC part with 1 (with leading zeros). The first release branch will have the RC 001.

For each of theses branches, the following commands will be executed:

$ git checkout $branch
$ git pull
$ git merge origin/main
$ git push origin $branch
$ git checkout $release_branch
$ git merge origin/$branch
$ git branch -D $branch

After merging all branches to the release branch, the branch will be pushed to origin.

Conflicts

If there are any conflicts during the merge of a branch, the braumeister will stop and write the current state to a release_state.json file. The output may looks like this:

$ braumeister -n "Barking Dog" candidate
[*] Requesting all issues with fixVersion: Barking Dog

A merge error occured while merging feature into release/Barking_Dog_RC_003

Please do the following steps:
	* Resolve the conflicts
	* Commit the changes
	* Call the script again with the option -r

The braumeister will stay in the current release branch to let you resolve the conflict. After the conflict has been resolved, you can rerun the braumeister with -r to resume where we stopped.
