- Simplify widget render methods by removing scroll parameters
- Clean up unused imports and legacy scrolling infrastructure
- Fix journalctl command to use -fu for proper log following
- Add new Status::Inactive variant to enum for better service state representation
- Agent now assigns Status::Inactive instead of Status::Warning for inactive services
- Dashboard displays inactive services with empty circle (○) icon in gray color
- User-stopped services still show as Status::Ok with green filled circle
- Inactive services treated as OK for host status aggregation

Improve user-stopped service tracking behavior:
Service Display Fix:
- Services widget now shows actual systemctl status (active/inactive)
- Use info.status instead of hardcoded text based on widget_status
- User-stopped services correctly display 'inactive' with green OK icon
- Prevents misleading 'active' display for stopped services
User-Stopped Flag Timing Fix:
- Clear user-stopped flag AFTER successful service start, not when command sent
- Prevents warnings during service startup transition period
- Service remains Status::OK during 'activating' state for user-stopped services
- Flag only cleared when systemctl start command actually succeeds
- Failed start attempts preserve user-stopped flag
Result: Clean service state tracking with accurate display and no false alerts
during intentional user operations.
Bump version to v0.1.45
- Fix service icons to use background color when selected for better visibility against blue selection background
- Combine start/stop service help text entries into single "s/S: Start/Stop Service"
- Change help text keys to lowercase (r: Rebuild Host, q: Quit)
- Bump version to v0.1.34
Major UI simplification and navigation improvements:
Changes:
- Removed panel selection concept entirely (no more Shift+Tab)
- Service selection always visible with blue highlighting
- Up/Down arrows now directly control service selection
- Added j/k vi-style navigation keys as alternatives to arrow keys
- Removed panel focus borders - all panels look uniform
- Service commands (s/S) work without panel focus requirements
- Updated keyboard shortcuts to reflect simplified navigation
Navigation:
- Tab: Switch hosts
- ↑↓/jk: Select service (always works)
- R: Rebuild host
- s: Start service
- S: Stop service
- q: Quit
The interface is now much simpler and more intuitive with direct service control.
Simplified keyboard controls by removing service restart functionality:
- Removed 'r' key restart functionality from Services panel
- Made 'R' key always trigger system rebuild regardless of focused panel
- Updated context shortcuts to show 'R: Rebuild Host' globally
- Removed all ServiceRestart enum variants and associated code:
- UiCommand::ServiceRestart
- CommandType::ServiceRestart
- ServiceAction::Restart
- Cleaned up pending transition logic to only handle Start/Stop commands
The 'R' key now consistently rebuilds the current host from any panel,
while 's' and 'S' continue to handle service start/stop in Services panel.
Resolved issues with transitional service icons not being properly visible:
- Removed 3-second timeout that was clearing pending transitions prematurely
- Fixed selection highlighting disappearing when transitional icons appeared
- Implemented conditional coloring for transitional icons:
- Blue when service is not selected
- Dark background color when service is selected (for visibility against blue selection)
- Transitions now persist until actual service status changes occur
Both selection highlighting and transitional icons are now visible simultaneously.
The root cause of transitional service icons not showing was that service names
were stored as raw names (e.g., "sshd") in pending_transitions but looked up
against formatted display lines (e.g., "sshd active 1M ").
Changes:
- Modified display_lines structure to include both formatted text and raw service names
- Updated rendering loop to use raw service names for pending transition lookups
- Fixed get_selected_service() method to use the new tuple structure
- Transitional icons (↑ ↓ ↻) should now appear correctly when pressing s/S/r keys
- Force sshd service to always show "↑ starting" for debugging
- Test if basic directional arrow rendering works in services widget
- Temporary debug change to isolate rendering vs logic issues
- Will help determine if problem is in pending transitions or rendering
If arrow appears: pending transitions logic issue
If no arrow: basic rendering path issue
- Store pending transitions even for redundant commands (start active service)
- Add 3-second timeout for redundant command visual feedback
- Include timestamp in pending transitions to enable timeout clearing
- Show directional arrows immediately regardless of command validation result
- Fix core issue where state validation prevented visual feedback storage
Now pressing s/S/r always shows immediate directional arrows, even for
redundant operations, providing consistent visual feedback to users.
- Prevent selection highlighting when service has pending transition
- Allow directional arrows (↑ ↓ ↻) to show through on selected services
- Fix core issue where selection styling was overwriting transitional icons
- Transitional icons now properly visible during service command execution
The selection highlighting logic now skips services with pending transitions,
ensuring that directional arrows are visible when executing service commands.
- Replace timeout-based command status with pending service transitions
- Show immediate directional arrows when pressing service commands (↑ ↓ ↻)
- Track original service status and command type for each pending operation
- Automatically clear transitional icons when real status updates arrive
- Remove unused TerminalPopup and CommandStatus infrastructure
- Simplify visual feedback system using state-based approach
Service commands now provide instant visual feedback that persists until
the actual service state changes, eliminating timing issues and improving UX.
- Add service state detection before executing start/stop/restart commands
- Prevent redundant operations (start active services, stop inactive services)
- Show immediate directional arrows for command feedback (↑ starting, ↓ stopping, ↻ restarting)

- Clean up all related dead code and fix compilation warnings
Benefits:
- Process isolation: rebuild runs independently via SSH
- Crash resilience: agent/dashboard can restart without affecting rebuilds
- Configuration flexibility: SSH user and alias configurable per deployment
- Operational simplicity: standard tmux popup interface
Replace generic hourglass with specific arrows:
- ↑ (up) for starting services
- ↓ (down) for stopping services
- ↻ (circular) for restarting services
Provides immediate visual feedback for service operations.
This implements the core functionality for executing remote commands through
the dashboard and providing real-time visual feedback to users.
Key Features:
- Remote service control (start/stop/restart) via existing keyboard shortcuts
- System rebuild command with maintenance mode integration
- Real-time visual feedback with service status transitions
- ZMQ command protocol extension for service and system operations
Implementation Details:
- Extended AgentCommand enum with ServiceControl and SystemRebuild variants
- Added agent-side handlers for systemctl and nixos-rebuild execution
- Implemented command status tracking system for visual feedback
- Enhanced services widget to show progress states (⏳ restarting)
- Integrated command execution with existing keyboard navigation
Keyboard Controls:
- Services Panel: Space (start/stop), R (restart)
- System Panel: R (nixos-rebuild switch)
- Backup Panel: B (trigger backup)
Technical Architecture:
- Command flow: UI → Dashboard → ZMQ → Agent → systemctl/nixos-rebuild
- Status tracking: InProgress/Success/Failed states with visual indicators
- Maintenance mode: Automatic /tmp/cm-maintenance file management
- Service feedback: Icon transitions (● → ⏳ → ● with status text)
Status Icon Color Preservation:
- Preserve original status icon colors (green ● for active, red ● for failed)
- Apply selection highlighting only to service text, not status icons
- Maintain visual health indicators while showing selection state
Focus-Aware Selection Display:
- Only show selection highlighting when Services panel is focused
- Hide selection bar when user switches to System or Backup panels
- Provides clean UI when not actively managing services
Selection Visual Behavior:
- Status icon: Original color (green/red/yellow) with blue background
- Service text: Blue background with black text for clear selection indication
- Unfocused state: All services display normally without selection artifacts
This creates optimal UX where status health information is always visible
and selection highlighting only appears when relevant for user interaction.
Selection Behavior Improvements:
- Limit selection to parent services only (docker, nginx, postgresql, etc.)
- Skip sub-services in navigation (no longer select nginx sub-sites)
- Up/Down arrows now move between actionable services only
Visual Enhancement:
- Preserve original status colors in selection highlighting
- Selected services show blue background with status foreground colors
- Green text for active services, red for failed, even when selected
- Maintains visual health status information during selection
Selection Logic:
- Add parent service index mapping for accurate selection tracking
- Only count parent services in total service count
- Calculate proper parent service index from display line position
- Ensure selection highlights only apply to parent services
This creates a cleaner UX where users only select services they can
actually control (start/stop/restart) while maintaining visual health
status indicators through preserved status colors.
Visual Highlighting Fixes:
- Apply selection highlighting to individual text spans instead of entire paragraph
- Eliminates highlighting of empty space below services on single-service hosts
- Selection now only highlights actual service text content
Selection Logic Improvements:
- Add proper bounds checking in select_next() to prevent invalid selections
- Automatically clamp selection index when services are updated
- Add debug logging to track selection state and movement
Bounds Safety:
- Ensure selection index stays valid when service lists change
- Prevent out-of-bounds access during service updates
- Reset selection to last valid index when services are removed
This fixes the issues where:
1. Single service hosts showed empty space highlighting
2. Multi-service hosts had no visible selection cursor
3. Selection could become invalid when services changed
Service Selection Features:
- Add selection cursor for Services panel with visual highlighting
- Up/Down arrows move service selection instead of scrolling
- Track selected service for future action implementation
- Selection state maintained per host
Panel Navigation Improvements:
- Fix panel switching to only cycle through visible panels
- Dynamic panel list based on backup data availability
- Smart recovery when focused panel becomes invisible
- No more navigation to hidden backup panel
Backup Panel Scrolling Fix:
- Fix backup panel scroll to show actual repository content
- Replace static overflow indicator with proper scroll behavior
