DB fields existed but were never surfaced in the TUI. Adds an HTTP
Settings form group with method select (7 methods) and accepted
codes input, visible only for HTTP monitors.
Expand alert provider count from 5 to 9. All new providers use
the shared HTTPProvider with closure-based payload functions.
Includes TUI form support and tests for each provider.
Replace all monitor package-level mutable state with Engine struct.
All state (liveState, logStore, histories, tokenIndex, HTTP clients)
is now encapsulated in Engine, created via NewEngine(store).
Key changes:
- Engine struct holds all monitor state with proper mutex protection
- Engine.Start(ctx) and monitorRoutine respect context cancellation
for graceful shutdown — no more leaked goroutines
- cluster.runFollowerLoop also respects context for clean exit
- Token index (map[string]int) for O(1) push heartbeat lookup,
replacing O(n) linear scan through LiveState
- UpdateSiteConfig preserves 8 runtime fields instead of copying
17 config fields individually
- triggerAlert goroutines get 30s timeout context
- All consumers (TUI, server, cluster, main) receive *Engine via
constructor/parameter — no package-level state access
- main.go creates context.WithCancel, passes to engine and cluster
First test suite: 12 tests across store and alert packages
- Store: CRUD for sites/alerts/users, push token generation,
import/export round-trip, check history persistence
- Alert: Discord/Slack/Webhook payload format, HTTP 4xx error
propagation, Ntfy headers, unknown provider returns nil
- New table_helpers.go with renderTable() and shared styles
- Remove 4 duplicated style blocks (header/cell/selected/border)
from tab_alerts.go and tab_users.go
- All 3 tab views now use renderTable() for offset/end calc,
selected row highlighting, and table construction
- Sites tab keeps siteGroupStyle via StyleOverride callback
- Clamp cursor to list length at end of refreshData() to prevent
index-out-of-bounds after concurrent list changes
- Fix off-by-one in tab click handler (i <= maxTabs → i < tabCount)
Remove store.Get()/SetGlobal()/Current. Store is now passed explicitly
to all consumers via constructor parameters and function arguments.
- TUI Model holds store field, set via InitialModel(isAdmin, store)
- monitor.StartEngine(s) and InitHistoryFromStore(s) accept store
- server.Start(cfg, s) closes over store in HTTP handlers
- main.go threads store to SSH server, TUI, monitor, server
- isKeyAllowed receives store as parameter
No more hidden dependency on package-level mutable state in store pkg.
Monitor package still uses package-level state (LiveState, etc.) — will
be encapsulated into Engine struct in Phase 7.
Every Store method now returns an error. Callers handle errors
gracefully — TUI logs to event log, server returns HTTP 500,
monitor engine logs and retries. All rows.Scan() errors are now
checked in sqlstore.go instead of silently appending corrupt data.
- GetSites, GetAllAlerts, GetAllUsers return ([]T, error)
- GetAlert returns (AlertConfig, error) instead of (AlertConfig, bool)
- AddSite, UpdateSite, DeleteSite, etc. all return error
- SaveCheck, LoadAllHistory, ExportData return error
- ~25 caller sites updated across tui, server, monitor, main
Use lipgloss StyleFunc to set per-column widths, with NAME as
the flex column absorbing remaining space. History column tied
to sparkWidth for consistency.
Groups act as visual organizers in the sites table. Monitors can be
assigned to a parent group via the form. Group rows show aggregated
worst-child status, children render with tree chars (├/└), and Space
toggles collapse/expand. Group form hides irrelevant connection and
advanced sections.
Prevent accidental deletes with y/n confirmation dialog. Validate all
numeric form inputs (interval, port, timeout, threshold, retries) with
range checks instead of silently defaulting to zero. Escape user-supplied
data in status page JavaScript to close XSS via monitor names. Persist
check history to new check_history table so sparklines and uptime
percentages survive restarts.
Per-site pause: [p] key toggles pause for selected monitor in TUI.
Paused monitors skip checks, persist to DB, show on status page.
Status page: replace full-page reload with fetch-based DOM updates
to eliminate scroll-jump on refresh. Add summary bar (UP/DOWN/PAUSED
counts), stale-data indicator, and fix SSL EXP CSS class bug.
TUI: constrain tables to terminal width via lipgloss .Width() to
prevent row wrapping that pushed header off-screen. Add MaxHeight
safety net. Bump subtle style from #383838 to #565f89 for
readability on dark terminals.
POST to ntfy server/topic with title, priority, and optional basic auth.
TUI alert form includes ntfy type with server URL, topic, priority
selector (1-5), and credential fields.
Add Hostname, Port, Timeout, Method, Description, ParentID, AcceptedCodes,
DNSResolveType, DNSServer, and IgnoreTLS fields. Refactor AddSite/UpdateSite
to accept models.Site instead of individual params. Includes DB migrations
for existing databases, per-monitor timeout/TLS in the engine, new type
options in TUI forms, and TYPE column in the sites table.
Users tab now matches sites/alerts quality: lipgloss bordered table,
click-to-select zones, edit form with role picker, and UpdateUser
support across both store backends.
Huh forms need all message types (timers, resize, etc.) not just
KeyMsg to function. Restructured Update to delegate all messages to
huh when in form state. Fixed selected row style to be visually
distinct from header (white text on darker bg). Moved click zone
from narrow ID cell to wider Name cell for better click targets.
Split monolithic tui.go into per-tab view files. Added sparkline history
tracking, color-coded latency/uptime, rounded bordered tables, Dracula-themed
huh forms with conditional groups, BubbleZone mouse click support for tabs
and rows, and Harmonica spring-physics pulse indicator. Includes --demo flag
for seeding test data.
