openstack/kolla-ansible — Week of 2026-08-29

Config templating. Jinja merge_configs gained lstrip_blocks alongside the existing trim_blocks, landing on master and picked up on a stable branch. The change tightens whitespace handling in generated service configs.

MariaDB and service tuning. The MariaDB backup role was reworked to back up from the local database instance rather than a remote target, and the fix was fanned out across four stable branches in identical form. On the Nova side, the nova_scheduler healthcheck timeout was extended to reduce spurious failures. An OVN Southbound fix corrected relay port calculation when the relay count exceeds nine — a latent arithmetic bug in 993718.

Cleanup. Two blocks of obsolete upgrade plumbing were removed: the Prometheus v3 volume migration code and the Cinder volumev3 handling in the upgrade path, both no longer needed by supported upgrade routes.

Tooling. A 2025.1-only CI tweak adds Valkey gate image builds, setup_gate.sh got a one-line fix, and a 2024.1 docs job pins setuptools to unblock tox.
