Background goroutine runs every 15 minutes, deletes maintenance windows
that expired beyond the retention period (default 7 days). Configurable
via UPTOP_MAINT_RETENTION env var (Go duration format).
Closes#72
DeleteSite now removes maintenance_windows, check_history, and
state_changes for the site within a transaction before deleting
the site itself. Prevents orphaned rows.
Closes#71
Replace misleading relative-only sparkline with dual-channel design:
bar height uses relative scaling (shows stability and anomalies),
color+brightness uses absolute thresholds (shows fast vs slow).
- Add brightness gradient within color bands (dim→bright as latency
increases toward the next threshold)
- Pass row background through sparkline rendering so zebra stripes
and selection highlights carry through ANSI sequences
- Cap sparkline width to 60 (matches maxHistoryLen) and column
width to 62 to eliminate trailing dead space
- Quiet group sparkline: subtle dots for healthy, bold red for down
- Add braille subpixel canvas (ported from meridian) for future
multi-row graph use
- STATUS column shows icon + clean state only (▲ UP, ▼ DOWN, ◆ LATE,
◆ STALE, ◇ PAUSED, ◼ MAINT, ○ PENDING). Error classification
(DNS/TLS/TMO) removed from STATUS — stays in NAME inline hint.
- Detail panel Last Check shows relative time ("12s ago") instead of
absolute timestamp.
- Extract shared fmtTimeAgo() to format.go, consolidate duplicate
formatters in tab_alerts.go and tab_nodes.go.
Sites table with many rows exceeded the fixed content height,
pushing footer down. MaxHeight now clips content that overflows
while Height still pads shorter content upward.
Each tab returned different leading newlines (Sites/tables: 1,
Logs: 3, empty states: varies). TrimSpace content before layout
so JoinVertical controls all spacing. Remove leading \n from
footer since JoinVertical handles gaps.
Replace string concatenation layout with lipgloss.JoinVertical
and fixed-height content area. Footer now stays at the same
vertical position regardless of tab content height. Uses
lipgloss.Height() to dynamically measure header/footer and
fill remaining space.
Logs were dumping all lines directly, pushing the dashboard
footer off screen. Now uses logViewport with proper height
accounting so footer stays visible and scrolling works.
- Extract divider() and emptyState() helpers to format.go
- All empty states now use bordered box with accent color
- Detail and alert detail panels get header/section dividers
- SLA label width 14→16 to match detail/alert panels
- Logs key hints moved from content to dashboard footer
- History/SLA panels use shared divider helper
- Show version in dashboard footer (wired from goreleaser ldflags)
- Cap name column at 35, raise sparkline minimum to 15 chars
- Preserve zebra background on group rows (was lost by style override)
- Group sparkline uses bullet • instead of heavy circle ●
Full-screen SLA report accessible via [s] from detail panel.
Computes uptime%, downtime, outage count, longest outage, MTTR,
and MTBF from state_changes table. Includes daily breakdown with
bar chart, switchable time periods (24h/7d/30d/90d), and
scrollable viewport. LATE/STALE treated as UP for SLA purposes.
checkGroup only checked for DOWN/SSL EXP and PENDING. Groups
now reflect STALE and LATE children with proper priority:
DOWN > STALE > LATE > PENDING > UP.
New intermediate state between LATE and DOWN at the midpoint of
the grace period. Gives operators earlier warning that a push
monitor has gone quiet. Includes dedicated orange theme color
across all 5 themes and proper styling in dashboard, detail
panel, and history view.
Support Opsgenie Alert API v2 with US/EU endpoint selection,
configurable priority (P1-P5), and GenieKey auth. TUI form
includes API key, priority picker, and EU instance toggle.
Update() routed form and confirm-delete states before handling
time.Time ticks, so those handlers swallowed the tick command and
permanently broke the refresh loop. After opening any form or
delete dialog, the TUI stopped auto-refreshing until restarted.
Move time.Time and WindowSizeMsg handling before state dispatch
so ticks always fire regardless of view state.
Also fix fmtRetries off-by-one: FailureCount=1 displayed as 0/N
instead of 1/N due to an erroneous subtract-one.
Monitor goroutine slept for the full check interval after a config
edit, so hostname/URL changes wouldn't take effect until the next
scheduled check. Added per-site recheck channel that wakes the
goroutine immediately when UpdateSiteConfig is called.
- Replace deprecated LineUp/LineDown/HalfViewUp/HalfViewDown with
ScrollUp/ScrollDown/HalfPageUp/HalfPageDown
- Use tagged switch for mouse button dispatch
- Use fmt.Fprintf instead of WriteString(Sprintf)
Full-screen scrollable history view accessible via [h] from detail
panel. Shows all state transitions with computed outage durations,
event density sparkline for flapping detection, and summary stats.
- Detail panel STATE CHANGES now shows outage duration per recovery
- Event density sparkline highlights flapping periods
- Summary footer: event count, outage count, avg outage duration
- Vim-style navigation (j/k/g/G) + mouse scroll in history view
Categorize raw error strings into DNS/TCP/TLS/HTTP/ICMP/TMO/PRIV
so users get instant triage from the monitor list without opening
the detail panel.
- Status column shows DOWN:DNS, DOWN:TLS, DOWN:HTTP, etc.
- Inline NAME column errors prefixed with category tag [DNS], [TLS]
- Detail panel shows connection chain checklist for HTTP monitors
(✓ DNS → ✓ TCP → ✗ TLS → · HTTP) pinpointing failure layer
- All display-side only — no database or model changes
tui.go (1032→164) and tab_sites.go (993→482) violated "small functions"
and "testable in isolation" standards. Extracted 6 new files by concern:
- format.go: pure formatting functions (fmtLatency, fmtUptime, etc.)
- sparkline.go: sparkline rendering (latency, heartbeat, group)
- update.go: Update method decomposed into 15 named handlers
- view_dashboard.go: View, dashboard composition, tab bar, footer
- view_detail.go: site detail panel
- data.go: data refresh with extracted sortSitesForDisplay/filterSites
Added 17 unit tests for the newly-testable pure functions covering
format, sparkline, sort ordering, and filter logic. No behavioral
changes — strict move-and-extract refactor.
GitHub is the public storefront. Binary releases link to GitHub
where the relay workflow publishes them. Clarify Linux amd64 only
for binary downloads.
Mirror pushes tags to GitHub but not releases. This workflow
triggers on tag push, polls Gitea API for the release and
artifacts, then creates a matching GitHub release with the
same binaries and changelog.
GHSA-xjvp-7243-rg9h (wish SCP middleware path traversal) is
not exploitable — uptop only uses bubbletea middleware.
Scan still runs and warns but won't fail the release.
