Supports `goupkeep version`, `--version`, and `-v`. Prints version,
commit hash, and build date when injected via ldflags. Shows "dev"
for local builds. Dockerfile updated with ARGs for version injection.
55 tests covering state machine transitions, heartbeat handling, push
deadline checks, group aggregation, history recording, probe aggregation,
log management, state management, and concurrency safety.
Checker tests cover HTTP (via httptest), port (via net.Listen),
isCodeAccepted ranges, and siteTimeout defaults. Ping and DNS
checkers skipped (need ICMP privileges and DNS server).
Coverage: 64.2% overall, 100% on handleStatusChange, triggerAlert,
checkPush, recordCheck, and AggregateStatus.
Monitors with the same interval no longer fire simultaneously.
Each tick adds up to 10% random jitter. Initial checks stagger
over 0-3s to avoid thundering herd on startup.
HTTP and SSH servers now shut down cleanly on SIGINT/SIGTERM with a
30s timeout. Database connection closed via defer. Replaced log.Fatalf
in SSH goroutine with log.Printf + ErrServerClosed check to prevent
unclean process exits.
Replace string equality checks on cluster secret with
crypto/subtle.ConstantTimeCompare to prevent timing attacks.
Add http.MaxBytesReader (1MB) to all POST endpoints that decode
JSON bodies. Change Start() to return *http.Server for graceful
shutdown support. Replace log.Fatalf with log.Printf in HTTP
server goroutine.
Provider.Send now accepts context.Context for timeout/cancellation.
HTTPProvider and NtfyProvider use NewRequestWithContext so HTTP alerts
respect the 30s deadline. triggerAlert logs send failures and config
load errors instead of silently swallowing them.
generateToken() now returns (string, error) instead of panicking on
crypto/rand failure. All json.Unmarshal calls for alert settings now
check and propagate errors instead of silently ignoring them.
Adds Close() to Store interface for graceful shutdown support.
Skips malformed notification entries during Kuma import.
Site count in tab label and footer now reflects total monitors
(excluding groups) regardless of collapse state. Down count also
computed from all sites so collapsed groups with down children
still surface in the badge. Replaced Nerd Font folder glyphs
with standard Unicode triangles for cross-font compatibility.
Add alternating row backgrounds for easier table scanning. Detail panel
now shows breadcrumb path (Sites > Group > Name) and min/avg/max latency
stats below the sparkline. Group collapse state persists across restarts
via new preferences table in both SQLite and Postgres.
Group rows now show selection background when navigated to. Layout
chrome extracted to named constants to prevent viewport drift. Groups
display aggregate history as dot sparkline (●) distinct from site
bar sparklines, with uptime computed from active children only.
Paused and maintenance children excluded from group aggregates.
Group status now treats maintenance'd children like paused ones —
they're excluded from the UP/DOWN calculation. Prevents group from
showing DOWN when its only failing child is under maintenance.
Forms overflowed past terminal because huh didn't know about the
surrounding chrome (header, footer, padding). Now sets WithHeight()
on every render and forwards WindowSizeMsg during form state.
Maintenance windows suppress alerts during planned downtime while checks
continue running. Incidents provide informational tracking. Supports
targeting all monitors, single monitor, or group (applies to children).
New Maint tab in TUI with create/end/delete. Status page, JSON API, and
Prometheus metrics all reflect maintenance state.
The public status JSON endpoint was serializing full Site structs
including heartbeat tokens. An attacker could extract tokens and
forge heartbeats to suppress DOWN alerts. Now tokens are stripped
before encoding. Backup/export endpoint is unaffected.
Arrow-style icons per monitor type plus Nerd Font folder icons for
groups (closed when collapsed, open when expanded):
