Features added:
- Send Unix signals to processes via interactive modal
- Support for common signals (HUP, INT, TERM, KILL, USR1, USR2, QUIT)
- Custom signal input for advanced use cases
- Safety confirmations for dangerous signals (TERM, KILL, QUIT)
- Signal button added to each ProcessCard
Implementation details:
- Created signal API routes:
- /api/supervisor/processes/[name]/signal - Send signal to process
- /api/supervisor/groups/[name]/signal - Send signal to group
- /api/supervisor/processes/signal-all - Send signal to all processes
- Added React Query hooks:
- useSignalProcess() - Send signal to single process
- useSignalProcessGroup() - Send signal to process group
- useSignalAllProcesses() - Send signal to all processes
- Created SignalSender modal component:
- Grid of common signal buttons with descriptions
- Custom signal text input (auto-uppercase)
- Two-step confirmation for dangerous signals
- Visual warning with AlertTriangle icon
- Destructive button variant for confirmed dangerous signals
- Backdrop blur overlay
ProcessCard enhancements:
- Added Zap icon signal button
- Modal opens on signal button click
- Button disabled when process is stopped
- Modal integrates with useSignalProcess hook
Common signals with descriptions:
- HUP (1): Reload configuration
- INT (2): Interrupt - graceful shutdown
- QUIT (3): Quit
- TERM (15): Terminate - graceful shutdown (dangerous)
- KILL (9): Kill - immediate termination (dangerous)
- USR1 (10): User-defined signal 1
- USR2 (12): User-defined signal 2
Safety features:
- Dangerous signals require confirmation
- Warning message explains risks
- Button changes to destructive variant
- Custom signals also checked for danger
- Clear visual feedback during operation
Phase 7 complete (3-4 hours estimated)
