Pull Request Overview
This PR refactors OpenStack branch inference by introducing a new script infer-openstack-branch.sh that dynamically determines the correct DevStack branch based on the OpenStack release name. This eliminates the need for hardcoded branch mappings and makes the system more maintainable as OpenStack releases transition between stable/* and unmaintained/* branches.
Key changes:
- New
infer-openstack-branch.shscript that queries GitHub to find the correct branch prefix for a given OpenStack release - Updated
bootstrap.shto useOPENSTACK_RELEASEenvironment variable instead ofDEVSTACK_BRANCH - Simplified constraints file handling with dynamic branch resolution
