From 2244818453dc02e9587f0d139ac90ef1eda14f53 Mon Sep 17 00:00:00 2001 From: AbdulmalikAlayande <114596864+AbdulmalikAlayande@users.noreply.github.com> Date: Sat, 13 Jun 2026 11:38:18 +0100 Subject: [PATCH 1/9] feat(db): add retry_count and webhook_secret columns to alert schema MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add retry_count column (INTEGER NOT NULL DEFAULT 0) to alerts_fired table to track how many delivery attempts have been made per alert. This enables the dispatcher to enforce a maximum retry limit and stop retrying permanently broken channels. Add webhook_secret column (TEXT, nullable) to alert_configs table to store per-config HMAC signing secrets for webhook authentication. Receivers can verify payload authenticity using the X-Sentinel-Signature header. Remove 'email' from alert_configs.channel_type CHECK constraint since email alerting is not implemented — silently accepting email configs was misleading users into thinking alerts would be delivered. Add live migration statements to database.ts so existing sentinel.db files created before these columns are seamlessly upgraded on next startup (ALTER TABLE with try/catch for idempotency).

Any entity that discovered the webhook URL could send fake alert payloads. sendWebhookAlert() now accepts an optional secret parameter. When provided: 1. Computes HMAC-SHA256 of the JSON body using the secret as key 2. Sends the signature as X-Sentinel-Signature: sha256= 3.

Users were told something was wrong (threshold_crossed) but never told when it recovered. This left operators uncertain whether manual intervention was still needed. When an entry's TTL recovers above the threshold: 1. resolveAlerts() now returns the list of alert_config_ids that were resolved 2. For each resolved config, build an alert_resolved AlertEvent 3. Deliver via deliverSingleAlert() — fire-and-forget, best-effort 4. Resolution delivery failures are logged but never block the monitor cycle This means every channel (webhook, Slack) that received a threshold_crossed alert will also receive an alert_resolved event when the TTL is extended back above the threshold, completing the alert lifecycle. Pass network parameter through to processContract() for correct event building (previously tried to access client.network which was private).

Users are directed to use 'webhook' or 'slack' instead. Add 'sentinel alerts test --id ' command: - Sends a synthetic test alert through the configured channel - Validates webhook URLs are reachable and Slack tokens are valid - Reports success/failure immediately - Essential for verifying channel connectivity before relying on it in production Add 'sentinel alerts history --contract [--limit N]' command: - Shows chronological alert history with delivery and resolution status - Status icons: ✓ resolved / ● active, ✓ delivered / ✗ undelivered - Includes TTL at fire time, channel info, and retry count - Defaults to 20 most recent records Add webhook HMAC secret support to 'alerts add': - Webhooks auto-generate a 32-byte hex secret on creation - Secret is displayed once and must be saved by the user - Can be overridden via --secret flag - 'alerts list' shows [signed] indicator for configs with secrets Remove --email option from 'alerts add' since the channel is blocked.
