feat(versioncheck): keep the install id in the database, with a derived fallback - #806
Conversation
…ed fallback The install id lived only in the data directory. In the Docker image that directory is part of the container, so every recreate without a volume minted a new id: the deployment showed up as a new instance and the old one as churned. The id now resolves in durability order: the runtime_settings store in the deployment's database, then the install-id file, then an HMAC of the master key, then a fresh UUID. Whichever wins is written back to the database and the file so they converge; the database wins a disagreement because the file is the copy that gets recreated by accident. An existing install-id file migrates unchanged, and a store that errors falls through to the file rather than creating a new identity. Deployments on SQLite whose data directory is on the container's overlay filesystem get a startup warning, since their whole database is in the same position. docker-compose.yaml mounts a gomodel_data volume there.

📝 WalkthroughWalkthroughThe gateway now stores install identity in runtime settings and mirrors it to a file. It supports database, file, master-key-derived, and generated identities. It detects ephemeral SQLite paths and adds persistent Docker Compose storage. ChangesInstall identity and persistence
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR makes deployment identity durable across databases, legacy files, and master-key-derived fallbacks, reducing churn after container recreation. During startup or database outages, instances may temporarily report fallback identities, and some documentation still does not accurately describe those cases, so merge is reasonable with explicit follow-up.

…olution Two replicas initialising against an empty database could each keep their own candidate: Set was last-writer-wins and the loser never re-read. The store now offers SetDefault, an atomic insert-if-absent that returns the stored winner (ON CONFLICT DO NOTHING; $setOnInsert upsert), and every resolver adopts what it returns. A database that was unreachable at startup no longer fixes a fallback id for the life of the process: the checker asks an Identity per request, which keeps the same provisional id while the outage lasts and switches to the database's id once it answers.

…ew nits The X-GoModel-Install header is asserted across two requests whose InstallIDFunc answer changes between them, so outage recovery cannot regress to a startup-fixed id. The runtime-settings test double's SetDefault now holds its lock across lookup and insert, matching the contract the real backends keep. The header table no longer calls the id random, since it may be derived or reused.

A blank value under the install_id key would have been adopted verbatim from SetDefault's read-back and settled as the deployment's identity; the local candidate now wins instead. ResolveInstallID had no production caller — the app wires Identity directly — so it moves into the test file as the helper it actually was.

The install id lived only in
install-idin the data directory. In the Docker image that directory is part of the container, so everydocker compose pull && upor pod reschedule without a volume minted a new id. In the install-base stats that shows up as a new instance plus a churned one for every recreate: "new instances" is inflated and retention deflated.Resolution order (
versioncheck.ResolveInstallID), most durable first:runtime_settingsin the deployment's database (SQLite, PostgreSQL, MongoDB) — the store the runtime settings already use;runtimesettings.NewStoreis exported for it.install-idfile — an existing id is adopted unchanged and migrated to the database, so upgrading never creates a new deployment.GOMODEL_MASTER_KEY— survives a container recreated with no storage at all. The key is never sent and cannot be recovered from the id.Whichever wins is written back to the database and the file. When they disagree the database wins: the file is the copy that gets recreated by accident, the database the one that gets migrated on purpose. A store that errors falls through to the file and skips the write-back, so a database that is briefly unreachable at startup can never mint a new identity.
