Outgoing notifications were bare POSTs with no auth and no way to verify
they came from Tinyforge. They also went out from one global URL only,
even though stages had a notification_url field, and static-site sync
emitted no events at all.
Schema: add notification_url + notification_secret (lazy-generated) to
settings, projects, stages and static_sites. Migrations are additive.
Notifier: SendSigned computes HMAC-SHA256 over the exact body bytes and
sends X-Hub-Signature-256 (GitHub-compatible — receivers built for
GitHub/Gitea/Forgejo verify out of the box). Aux headers
X-Tinyforge-Event/Delivery/Timestamp/Tier are advisory and not signed.
Empty secret => unsigned send for back-compat.
Resolution: deploys fall through stage > project > settings, sites fall
through site > settings. The secret travels with the URL that sourced
it, so any tier can sign even when its parents are unsigned. Site sync
events now actually emit (site_sync_success / site_sync_failure).
API: 12 new endpoints — {GET secret, POST regenerate, POST disable,
POST test} for each of the 4 tiers. SendSyncForTest returns
status_code/latency_ms/signature_sent/delivery_id/response_snippet so
the UI surfaces receiver feedback inline.
UI: shared OutgoingWebhookPanel.svelte fits the existing card aesthetic.
Signing-state pill, secret reveal-on-demand, regenerate/disable behind
ConfirmDialog modals (not inline strips — too easy to misclick), send-
test result card with colour-coded status. Wired into Settings →
Integrations, project edit form, per-stage edit, and per-site detail.
EN + RU i18n.
Tests: round-trip (sender signs, receiver verifies), tampered-body and
wrong-secret rejection, unsigned-send omits header, send-test surfaces
4xx, concurrent fan-out via Drain. Resolver precedence locked for both
deploy and site paths.
Docs: docs/webhooks.md with header reference, verifier snippets in
Node/Python/Go, and a recipe for the service-to-notification-bridge
generic webhook provider.
Security:
- rate limit /api/webhook routes per-IP and cap concurrent site syncs
- global SSE connection cap (256) with new sse_gate
- validate ?tail= and cap JSON log responses at 4 MiB
- strip ANSI/CSI/OSC and control bytes from streamed log lines
- redact webhook secret from request log middleware
- scrub host details from /api/health for non-admin viewers
- drop container_id from /api/system/stats/top for non-admins
- generate webhook secrets via crypto/rand; require >=32 chars on insert
- verify iid path consistency in streamContainerLogs
- LimitReader on site webhook body; reject malformed non-empty bodies
Concurrency / correctness:
- stats collector: Stop() no longer hangs without Start(), semaphore
acquired in parent loop so ctx cancellation short-circuits the queue,
in-flight tick cancellable via shared base context, zero-ts guard
- webhook handler: replace fire-and-forget goroutine with WaitGroup-tracked
workers + Drain() wired into graceful shutdown
- $derived(() => ...) mis-idiom fixed in ContainerStats / InstanceCard /
ProjectCard (returned function instead of value)
- SystemResourcesCard: rename `window` and `t` locals to avoid shadowing
globalThis.window and the i18n `t` import
Quality / performance:
- replace O(n^2) insertion sort with sort.Slice in stats top
- runMigrations only swallows duplicate-column / already-exists errors
- PruneStatsSamplesBefore wrapped in a transaction
- collapse N+1 in unusedImageStats / pruneImages to one ListAllInstances
pass; surface DB errors instead of silently treating them as inactive
- run Docker Info + DiskUsage in parallel via errgroup
- container log SSE emits `: ping` heartbeat every 20 s
- imageMatches case-insensitive on registry host (RFC behaviour)
- log warning on invalid stage tag pattern instead of silent skip
- reject malformed non-empty site webhook payloads
Frontend / i18n:
- shared formatBytes utility replaces three local copies
- statsInterval store drives dynamic "no samples / collection disabled"
copy across ContainerStats and SystemResourcesCard
- top consumers row now shows owner_name (project/stage or site name)
- drop seven `as any` casts on the Settings type; add cloudflare_api_token
write-only field
- move "Service status", "Docker daemon", "Docker unreachable",
"Proxy unreachable", "reachable", and "Docker daemon is not reachable."
strings into en/ru i18n bundles
- CRITICAL: Change DNS zones endpoint from GET to POST to avoid
leaking API token in URL query parameters
- HIGH: Add sync.RWMutex to protect dnsProvider field in Server,
Deployer, and proxy Manager against concurrent read/write races
- HIGH: Capture old DNS provider reference synchronously before
launching background cleanup goroutine
- HIGH: Use getDNS()/getDNSProviderLocked() accessors instead of
direct field reads in all DNS operations
