Enforces each webhook's RetentionDays so per-webhook SQLite files no longer grow without bound.

Reaper

New RetentionReaper in internal/database/retention.go. A background ticker runs each sweep: it lists all webhooks from the main DB and, for each webhook with a positive RetentionDays, opens its per-webhook DB via WebhookDBManager.GetDB and deletes every Event (and its dependent Delivery and DeliveryResult rows) whose CreatedAt is older than RetentionDays days.

  • Deletions run in foreign-key-safe order: delivery results, then deliveries, then events.
  • Deletes are unscoped (hard deletes) so rows are physically removed and disk is reclaimed, rather than GORM soft-deleting them.
  • RetentionDays <= 0 means retain forever; those webhooks are skipped.
  • Webhooks whose per-webhook DB does not yet exist are skipped.

Config

internal/config/config.go gains RetentionSweepInterval (env RETENTION_SWEEP_INTERVAL, parsed as a Go duration, default 1h) via a new envDuration helper, following the existing env-helper conventions.

Wiring

cmd/webhooker/main.go registers database.NewRetentionReaper as an fx provider and forces its construction in fx.Invoke. The reaper starts its sweep loop on an fx OnStart hook and stops cleanly on OnStop via context cancellation, matching the existing lifecycle components.

Test

internal/database/retention_test.go seeds an old event chain (event + delivery + result, 40 days old) and a recent one (1 day old) in a real per-webhook DB and asserts a single sweep removes only the expired chain while keeping the recent one. A second test forces a non-positive RetentionDays and asserts an ancient event is retained.

Note: the Webhook.RetentionDays column carries gorm:"default:30", so a 0 passed to a GORM Create is replaced by the default; the test forces the value with an explicit column update to exercise the retain-forever path. No model changes were made.

Validated with docker build . (fmt-check, lint, test, build) exit 0.

Closes #63

Enforces each webhook's `RetentionDays` so per-webhook SQLite files no longer grow without bound. ## Reaper New `RetentionReaper` in `internal/database/retention.go`. A background ticker runs each sweep: it lists all webhooks from the main DB and, for each webhook with a positive `RetentionDays`, opens its per-webhook DB via `WebhookDBManager.GetDB` and deletes every `Event` (and its dependent `Delivery` and `DeliveryResult` rows) whose `CreatedAt` is older than `RetentionDays` days. - Deletions run in foreign-key-safe order: delivery results, then deliveries, then events. - Deletes are unscoped (hard deletes) so rows are physically removed and disk is reclaimed, rather than GORM soft-deleting them. - `RetentionDays <= 0` means retain forever; those webhooks are skipped. - Webhooks whose per-webhook DB does not yet exist are skipped. ## Config `internal/config/config.go` gains `RetentionSweepInterval` (env `RETENTION_SWEEP_INTERVAL`, parsed as a Go duration, default `1h`) via a new `envDuration` helper, following the existing env-helper conventions. ## Wiring `cmd/webhooker/main.go` registers `database.NewRetentionReaper` as an fx provider and forces its construction in `fx.Invoke`. The reaper starts its sweep loop on an fx `OnStart` hook and stops cleanly on `OnStop` via context cancellation, matching the existing lifecycle components. ## Test `internal/database/retention_test.go` seeds an old event chain (event + delivery + result, 40 days old) and a recent one (1 day old) in a real per-webhook DB and asserts a single sweep removes only the expired chain while keeping the recent one. A second test forces a non-positive `RetentionDays` and asserts an ancient event is retained. Note: the `Webhook.RetentionDays` column carries `gorm:"default:30"`, so a `0` passed to a GORM `Create` is replaced by the default; the test forces the value with an explicit column update to exercise the retain-forever path. No model changes were made. Validated with `docker build .` (fmt-check, lint, test, build) exit 0. Closes #63

What changed

Added a per-webhook event retention reaper that enforces RetentionDays.

Files changed (5, +604/-5):

  • internal/database/retention.go (new): RetentionReaper with fx OnStart/OnStop hooks, a ticker-driven run/sweep, and reapExpired which hard-deletes (unscoped) delivery results, then deliveries, then events older than the cutoff, in FK-safe order. Skips webhooks with RetentionDays <= 0 and those with no per-webhook DB yet.
  • internal/config/config.go: new RetentionSweepInterval field (env RETENTION_SWEEP_INTERVAL, default 1h) plus an envDuration helper and log-summary line.
  • cmd/webhooker/main.go: registers database.NewRetentionReaper as a provider and constructs it via fx.Invoke.
  • internal/database/retention_test.go (new): seeds old (40d) and recent (1d) event+delivery+result chains and asserts only the expired chain is removed; a second test forces a non-positive RetentionDays and asserts retain-forever.
  • internal/database/export_test.go (new): test-only bridge exposing a reaper constructor and a synchronous single-sweep trigger.

None of routes.go, http.go, engine.go, source_management.go, or middleware.go were touched.

Validation

docker build . (fmt-check, lint, test, build):

docker build exit code: 0

this should fail loudly and prevent server startup if it can't parse the duration string in the env var. your implementation silently fails. bad.

Independent review — PASS (merge-ready)

Adversarial review against the issue spec and repo policies.

  • internal/database/retention.go: RetentionReaper runs a ticker sweep (configurable RetentionSweepInterval, env RETENTION_SWEEP_INTERVAL, default 1h) started on fx OnStart and stopped cleanly on OnStop via context cancel plus a WaitGroup. Each sweep lists webhooks, skips a RetentionDays of 0 or less (retain forever) and webhooks with no per-webhook DB yet, and reaps the rest; it also checks context cancellation between webhooks.
  • reapExpired hard-deletes (Unscoped) in foreign-key-safe order — delivery results, then deliveries, then events — for events older than the cutoff, building fresh subquery builders per statement. Good catch on the soft-delete trap: BaseModel has a DeletedAt, so a plain Delete would only soft-delete and never reclaim disk; Unscoped physically removes the rows.
  • Wiring: the NewRetentionReaper fx provider is registered and constructed in fx.Invoke (cmd/webhooker/main.go); the new envDuration config helper follows the existing env-helper conventions.
  • Tests: seed a 40-day-old and a 1-day-old event/delivery/result chain under a 30-day policy and assert only the expired chain is reaped; a second test asserts retain-forever for a non-positive RetentionDays (forcing the value past GORM's default-of-30 with an explicit column update). docker build . green; no AI/tooling references; commit closes the issue.
  • Scope respected: none of the in-flight files (engine.go, routes.go, etc.) were touched.

One follow-up, not blocking this PR: a RetentionDays of 0 is unreachable through a normal create because the column default is 30, so "retain forever" cannot currently be expressed via the create path. Filed separately.

Verdict: meets the bar. Marking merge-ready and handing to @sneak for final review.

You're right, and I should have caught this in review — my miss. envDuration silently falls back to the default when RETENTION_SWEEP_INTERVAL is set but unparseable; a bad config value must fail loudly and prevent startup, not be silently ignored.

Sending it back for rework: envDuration will return an error on a set-but-unparseable value, and config.New will propagate it so startup aborts. An unset value still uses the default. Reassigning to clawbot — off your plate until it is fixed and re-reviewed.

(Also filing the same silent-default pattern in the other env helpers as a follow-up.)

Reworked per review: a set-but-unparseable RETENTION_SWEEP_INTERVAL now fails startup loudly instead of silently falling back to the default.

Changes (in internal/config/):

  • envDuration(key, defaultValue) now returns (time.Duration, error). If the env var is unset it returns (defaultValue, nil); if set and valid, (parsed, nil); if set but time.ParseDuration fails, it returns a wrapped error naming the key and the bad value (invalid duration for %s: %q: %w).
  • config.New calls the new envDuration for RETENTION_SWEEP_INTERVAL and returns any error, so fx aborts startup rather than swallowing it.
  • envInt/envString are deliberately left unchanged (separate follow-up).
  • Added TestRetentionSweepInterval covering: unset uses the 1h default, a valid 15m is parsed, and an unparseable not-a-duration makes config.New fail (asserted via app.Err()). Env vars are set/unset hermetically with t.Setenv / os.Unsetenv.

Validation: docker build (fmt-check, lint, test, build) exits 0:

Re-review after rework — PASS (merge-ready)

Verified the fail-loud fix on internal/config/config.go:

  • envDuration now returns (time.Duration, error): an unset variable returns the default with no error; a set-and-valid value is parsed; a set-but-unparseable value returns a wrapped error naming the key and the bad value (invalid duration for %s: %q).
  • config.New calls it for RETENTION_SWEEP_INTERVAL and returns the error before constructing the config, so fx aborts startup instead of silently falling back to the default.
  • The test covers all three cases — unset to default, valid parsed, and unparseable causing config.New to error — set hermetically via t.Setenv. docker build . green.

The remaining silently-defaulting helpers (envInt, envBool) are tracked separately in #80, out of scope for this PR.

Verdict: the flagged defect is resolved. Re-assigning to @sneak for final review.
