From 0336c85cec640cb396e69ff06095728c7706fa1f Mon Sep 17 00:00:00 2001 From: Shreyas Goenka Date: Mon, 7 Sep 2026 03:51:11 +0200 Subject: [PATCH] bundle/dstate: nullify local state when DMS recording is enabled When opening a deployment state with experimental.record_deployment_history enabled, the service is the source of truth for resources, not the local state file. Nullify the local state so it acts as a tombstone (carrying only the feature marker and header). This allows stale local state from a destroyed DMS deployment to bootstrap a fresh deployment, instead of erroring with "this deployment already exists and is not recorded". The fix removes the guard that previously prevented enabling DMS on deployments with local resources. This is a necessary tradeoff to support the common scenario where a DMS deployment is destroyed on the service but the local state cache remains. The service is now authoritative: - If dmsDeploymentID is non-empty: ListResources fetches the service's resources - If dmsDeploymentID is empty: no resources are loaded (fresh/destroyed deployment) Tradeoff: this also allows enabling DMS on an existing non-DMS deployment, which could leave old resources orphaned if they have different IDs or names. Users should destroy a non-DMS deployment before enabling DMS to avoid this scenario. Accept this tradeoff to unblock the more common case (destroyed DMS bootstrap).
