Project Branches

There are two types of branches in the Messaging Toolkit:

• Active Branch - This is a branch where active development is done. New features and enhancements can be added to this branch.
• Maintenance Branch - A maintenance branch for building maintenance releases for the toolkit. No new features or enhancements can be made to the maintenance branch. Maintenance branch is named with a "_m" postfix in the branch name to indicate that the branch is for maintenance. Only critical customer fixes can be delivered to this branch. If a fix is required to be made to the maintenance branch, the fix needs to goes through a review process:
  • Contributor / Committer creates a fix for the customer problem.
  • The contributor asks another committer to review the fix, to ensure the the fix is properly tested and implemented.
  • If the fix is good, the reviewer will add a +1 vote.
  • A fix cannot be delivered to the maintenance branch without a +1 vote from another committer.
