Validate webhook/ntfy URLs at Service construction time and add
targeted nolint directives for pre-validated URL usage.
Fix goimports formatting in tlscheck_test.go.
Replace DNSWATCHER_DOMAINS and DNSWATCHER_HOSTNAMES with a single
DNSWATCHER_TARGETS env var. Names are automatically classified as apex
domains or hostnames using the Public Suffix List
(golang.org/x/net/publicsuffix).
- ClassifyDNSName() uses EffectiveTLDPlusOne to determine type
- Public suffixes themselves (e.g. co.uk) are rejected with an error
- Old DOMAINS/HOSTNAMES vars removed entirely (pre-1.0, no compat needed)
- README updated with pre-1.0 warning
Closes#10
Implements the full monitoring loop:
- Immediate checks on startup, then periodic DNS+port and TLS cycles
- Domain NS change detection with notifications
- Per-nameserver hostname record tracking with change/failure/recovery
and inconsistency detection
- TCP port 80/443 monitoring with state change notifications
- TLS certificate monitoring with change, expiry, and failure detection
- State persistence after each cycle
- First run establishes baseline without notifications
- Graceful shutdown via context cancellation
Defines DNSResolver, PortChecker, TLSChecker, and Notifier interfaces
for dependency injection. Updates main.go fx wiring and resolver stub
signature to match per-NS record format.
Closes#2
