Execution only prints messages; it does not fence users or delete data. Discovery combines explicit relay memberships with active channel memberships, including users who have no relay membership row. It deduplicates communities and preserves owner relationships. The saved manifest contains only community IDs, labels and relationships. Historical discovery and owned-community execution remain later work. Submission rejects owner inventories atomically with a specific unsupported-execution error; preview still includes owners. This is an expand-schema change after #8520. Migrations 0072–0073 replace the demo-only target check with a bounded identifier check, with 5-second lock and 30-second statement timeouts. The database keeps the user-only entity-type check while allowing different identity formats in the target field. Workflow-specific commands reject entity types they cannot execute. The application currently resolves demo and hex/npub inputs; account-ID lookup is future work. The desired-state constraint matches. No backfill, trigger, function, or foreign key is added. Existing demo rows remain valid. Old binaries fail closed on new manifests; use the new CLI for their approval and execution. Older auto-migrating binaries need the documented rollback procedure. Identity parsing and demo fixture selection stay in intake. Approval and resume use the saved target without reparsing its format. The user workflow defines its stage names and handlers; CLI stage validation reads those rules instead of a separate three-name list. Shared persistence accepts caller-defined stages. Permanent target uniqueness is unchanged. Dummy submissions and execution belong in isolated, disposable development databases; production preview uses read-only access. CLI operator names remain self-asserted. ### Related issue Follows #8520. Searched open PRs; no duplicate inventory change found. #8489 is earlier workflow scaffolding. ### Testing Built `buzz-admin` locally and applied all migrations to a fresh disposable PostgreSQL database. Ran the actual CLI through preview → submit → inspect → approve → `run --next-step` → resume → completed for both demo and a public key with a channel-only membership fixture. Demo completed five stages; the public-key run completed three. Injected `--fail-stage purge_db`, waited for the retry deadline, and resumed the same failed stage successfully. Membership data remained intact. Repeated the CLI workflow on October 26 for demo and an npub backed by a fresh production inventory. Production access used read-only credentials and the real `inventory --pubkey "$SUBJECT"` handler. Copied only the relevant discovery fields into an isolated local PostgreSQL database; local channel parent rows supplied placeholder fields for foreign keys. The inventory saved by local submission exactly matched the production result. All workflow writes stayed local. For each input, ran `submit --pubkey "$SUBJECT" --requested-by local-e2e-submitter`, inspected the saved inventory, and confirmed execution before approval was rejected. Approved its digest, then ran each handler with `run "$REQUEST_ID" --next-step --stage-delay-ms 2500` in a new process. Captured all three workflow tables during and after every stage. Demo completed five stages across two communities; the npub completed three stages for its discovered community. Each handler saved `dummy: true`. Both requests finished with no current stage, no worker lease, and no retries. Copied memberships remained intact. This additional run exercised orderly resume; it did not inject a failure. The reproducible command sequence and fixture setup are in [the inventory walkthrough](docs/operator-user-deletion-inventory.md). Production was not changed. The earlier full-workflow runs used synthetic local fixtures; the additional npub run used captured production discovery fields. Repository-wide `just ci` was not run; validation focused on the affected packages and PostgreSQL workflow. The pre-push desktop build failed with “Too many open files in system.” Stopped the broader hook run and bypassed it to publish the earlier commits; the affected-package Clippy and formatting checks had passed.

Luke Tornquist	c6340a45a0	fix(deletion): give the scheduled drain the cold-start DB connector (#8146) ... ## Summary The scheduled `buzz-admin deletions drain` Job never gets past its first database connection in a hosted staging deployment. Every run exits 5 after exactly 3 seconds with `pool timed out while waiting for an open connection`. The drain starts in a fresh pod with no mesh sidecar, and that pod's first connection can take longer than the relay's 3-second acquisition budget. `connect_store()` in `buzz-deletion` inherits that budget from `DbConfig::default()`, with no retry. In the same pod, the same command run 15 seconds later succeeds. TCP to Postgres, Redis, and S3 from a sidecar-less pod is fine. #7770 fixed the same failure for `buzz-admin storage-snapshot`, but only inside `buzz-admin`. This PR moves that connector into `buzz-db` as `Db::connect_cold_start` and uses it from both run-once workers: - **Pool settings:** a 30s acquisition budget, and no idle spare connections (`min_connections: 0`). - **Retries:** startup timeouts and transient transport errors retry at most twice, after 2s and 5s, so startup waits at most 97s. - **No retry:** configuration, authentication, TLS, and protocol errors fail immediately, and the error message stays free of credentials. - **Per-worker settings:** each worker keeps its own pool size. Storage-snapshot stays at 1 connection, and deletion stays at `BUZZ_DB_POOL_SIZE` (default 20). Each worker also keeps its session timeouts. - **Startup events:** the stderr events carry a worker prefix. Storage-snapshot still emits `storage_snapshot_db_connect_*`, and the deletion worker now emits `deletion_db_connect_*`. - **Error text:** the exhaustion message is now `{worker} database startup failed after …`. For storage-snapshot that reads `storage_snapshot database startup failed …` instead of `storage snapshot database startup failed …`. Nothing in this repo matches on that string. - **Session-setup failures:** SQLx retries a failed `after_connect` hook (writer floor guard, session timeouts, isolation assertion) until the acquire deadline. Those failures therefore surface as `timeout`, are retried, and fail closed after at most 97s instead of immediately. Relay pool defaults are unchanged. The deletion CLI's operator commands (`list`, `approve`, …) use the same connector. They normally run inside the warm relay container, where the first attempt succeeds. **What got simpler:** there is now one cold-start connector instead of a `buzz-admin`-private copy that the deletion worker couldn't reach. `storage_snapshot_startup.rs` is gone, and its unit tests moved with the code. The two Postgres startup tests now share one harness with the drain's tests (`postgres_storage_snapshot.rs` → `postgres_cold_start.rs`). ### Related issue Follow-up to #7770 (same failure, other worker) and #7827 (the drain CronJob). No duplicate found. ### Testing All at head `1545de7b5`: - **GitHub CI:** green on attempt 1, including `PostgreSQL Domain / PostgreSQL Tests`. - **Blox:** - fmt, `clippy --workspace --all-targets -D warnings`, and the `buzz-db` / `buzz-admin` / `buzz-deletion` tests pass. - All four `postgres_cold_start` tests pass, each against a freshly migrated database. - Falsification: with main's `connect_store` restored, the drain retry test fails. - **Agent review:** two rounds. All findings are fixed or disclosed; the error-text change is listed above. - **Agent exercise:** real `buzz-admin deletions list` / `deletions drain` against local Postgres 17 behind a fault proxy. - **5s delay:** succeeds on attempt 1 (3/3). Main fails at about 3.5s. - **Dropped handshake, then 5s delay:** attempt 1 fails with `UnexpectedEof`, then a 2s backoff, then attempt 2 succeeds (3/3). - **Wrong password, missing database or malformed URL:** exit 5 after one attempt. - **Persistent rejection:** exit 5 after three attempts, with 2s and 5s backoffs. - The deletion queue stayed empty throughout. - **Not covered:** an approved deletion, real S3 / Pod Identity, TLS and session-setup failures, and a live 97s stall. --------- Signed-off-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz>	2026-10-08 10:30:38 -04:00
ravarora2	a929532a04	fix(admin): allow cold storage worker DB startup (#7770) ... ## Summary The standalone S3 accounting worker can exit before its scan begins because database startup inherits the relay’s three-second connection budget. A cold DNS probe took about five seconds. Give `buzz-admin storage-snapshot` its own pool: one connection, no minimum idle connections, and a 30-second acquisition budget. Retry startup timeouts and transport failures at most twice, after two and five seconds. Total startup wait is bounded to 97 seconds. Configuration, authentication, TLS, and protocol errors fail immediately. Log each startup attempt’s elapsed time and error category without connection credentials. Relay defaults stay unchanged. Retries stop before lock acquisition; the same lock-owning database session still publishes the completed snapshot. ### Related issue Follow-up to #7543. No duplicate startup fix found. ### Testing Archived-command check: built a nextest archive, temporarily moved `target/debug/buzz-admin` out of the checkout, and ran `scripts/postgres-test-run.sh --archive-file <archive>`. Both tests failed before the path fix and passed afterward. The tests use nextest’s relocated executable path, with the original Cargo path retained for local runs. Manually restored the old startup call and ran `scripts/postgres-test-run.sh -p buzz-admin --test postgres_storage_snapshot -E 'test(storage_snapshot_retries_then)'`. It failed before reaching S3; restoring the fix passed. This confirms the test exercises the actual worker command. Local `just ci` passed all stages before mobile tests, which stopped at SDK discovery in the `objective_c` native hook. The default Xcode tools report an unaccepted license. Two existing PostgreSQL tests hit connection timeouts in the parallel run and passed individually. After merge, build a worker image and repeat the cold-pod staging smoke test through snapshot publication before changing relay metrics mode.
