 # Changelog

+## 2025-08-26 - 1.8.0 - feat(daemon)
+Add real-time log streaming and pub/sub: daemon publishes per-process logs, IPC client subscribe/unsubscribe, CLI --follow streaming, and sequencing for logs
+
+- Upgrade @push.rocks/smartipc dependency to ^2.1.2
+- Daemon: initialize SmartIpc server with heartbeat and publish process logs to topic `logs.<processId>`; write PID file and start heartbeat monitoring
+- Tspm: re-emit monitor log events as 'process:log' so daemon can broadcast logs
+- ProcessWrapper: include seq and runId on IProcessLog entries and maintain nextSeq/runId (adds sequencing to logs); default log buffer size applied
+- TspmIpcClient: improved connect options (retries, timeouts, heartbeat handling), add subscribe/unsubscribe for real-time logs, and use SmartIpc.waitForServer when starting daemon
+- CLI: add --follow flag to `logs` command to stream live logs, detect sequence gaps/duplicates, and handle graceful cleanup on Ctrl+C
+- ProcessMonitor: now extends EventEmitter and re-emits process logs for upstream consumption
+- Standardized heartbeat and IPC timing defaults (heartbeatInterval: 5000ms, heartbeatTimeout: 20000ms, heartbeatInitialGracePeriodMs: 10000ms)
+
+## 2025-08-25 - 1.7.0 - feat(readme)
+Add comprehensive README with detailed usage, command reference, daemon management, architecture and development instructions
+
+- Expanded README from a short placeholder to a full documentation covering: Quick Start, Installation, Command Reference, Daemon Management, Monitoring & Information, Batch Operations, Architecture, Programmatic Usage, Advanced Features, Development, Debugging, Performance, and Legal information
+- Included usage examples and CLI command reference for start/stop/restart/delete/list/describe/logs and batch/daemon commands
+- Added human-friendly memory formatting and examples, process and daemon status outputs, and programmatic TypeScript usage snippet
+- Improved onboarding instructions: cloning, installing, testing, building, and running the project
+
 ## 2025-08-25 - 1.6.1 - fix(daemon)
 Fix smartipc integration and add daemon/ipc integration tests

-a no fuzz process manager
+**TypeScript Process Manager** - A robust, no-fuss process manager designed specifically for TypeScript and Node.js applications. Built for developers who need reliable process management without the complexity.

-## How to create the docs
+## 🎯 What TSPM Does

-To create docs run gitzone aidoc.
+TSPM is your production-ready process manager that handles the hard parts of running Node.js applications:
+
+- **Automatic Memory Management** - Set memory limits and let TSPM handle the rest
+- **Smart Auto-Restart** - Crashed processes come back automatically (when you want them to)
+- **File Watching** - Auto-restart on file changes during development
+- **Process Groups** - Track parent and child processes together
+- **Daemon Architecture** - Survives terminal sessions with a persistent background daemon
+- **Beautiful CLI** - Clean, informative terminal output with real-time status
+- **Structured Logging** - Capture and manage stdout/stderr with intelligent buffering
+- **Zero Config** - Works out of the box, customize when you need to
+

+Memory:      45.2 MB
+CPU:         0.1%
+```
+
+## 🏗️ Architecture
+
+TSPM uses a three-tier architecture for maximum reliability:
+
+1. **ProcessWrapper** - Low-level process management with stream handling
+2. **ProcessMonitor** - Adds monitoring, memory limits, and auto-restart logic
+3. **Tspm Core** - High-level orchestration with configuration persistence
+
+The daemon architecture ensures your processes keep running even after you close your terminal. All process communication happens through a robust IPC (Inter-Process Communication) system.
+
+## 🎮 Programmatic Usage
+
+TSPM can also be used as a library in your Node.js applications:
+
+```typescript
+import { Tspm } from '@git.zone/tspm';
+
+const manager = new Tspm();
+
+// Start a process
+const processId = await manager.start({
+  id: 'worker',
+  name: 'Background Worker',
+  command: 'node worker.js',
+  projectDir: process.cwd(),
+  memoryLimitBytes: 512 * 1024 * 1024, // 512MB
+  autorestart: true,
+  watch: false
+});
+
+// Monitor process
+const info = await manager.getProcessInfo(processId);
+console.log(`Process ${info.id} is ${info.status}`);
+
+// Stop process
+await manager.stop(processId);
+```
+
+## 🔧 Advanced Features
+
+### Memory Limit Enforcement
+TSPM tracks memory usage including all child processes spawned by your application. When a process exceeds its memory limit, it's gracefully restarted.
+
+### Process Group Tracking
+Using `ps-tree`, TSPM monitors not just your main process but all child processes it spawns, ensuring complete cleanup on stop/restart.
+
+### Intelligent Logging
+Logs are buffered and managed efficiently, preventing memory issues from excessive output while ensuring you don't lose important information.
+
+### Graceful Shutdown
+Processes receive SIGTERM first, allowing them to clean up. After a timeout, SIGKILL ensures termination.
+
+### Configuration Persistence
+Process configurations are saved, allowing you to restart all processes after a system reboot with a single command.
+
+## 🛠️ Development
+
+```bash
+# Clone the repository
+git clone https://code.foss.global/git.zone/tspm.git
+
+# Install dependencies
+pnpm install
+
+# Run tests
+pnpm test
+
+# Build the project
+pnpm build
+
+# Start development
+pnpm start
+```
+
+## 🐛 Debugging
+
+Enable debug mode for verbose logging:
+
+```bash
+export TSPM_DEBUG=true
+tspm list
+```
+
+## 📊 Performance
+
+TSPM is designed to be lightweight and efficient:
+- Minimal CPU overhead (typically < 0.5%)
+- Small memory footprint (~30-50MB for the daemon)
+- Fast process startup and shutdown
+- Efficient log buffering and rotation
+
+## 🤝 Why TSPM?
+
+Unlike general-purpose process managers, TSPM is built specifically for the TypeScript/Node.js ecosystem:
+
+- **TypeScript First** - Written in TypeScript, for TypeScript projects
+- **ESM Native** - Full support for ES modules
+- **Developer Friendly** - Beautiful CLI output and helpful error messages
+- **Production Ready** - Battle-tested memory management and error handling
+- **No Configuration Required** - Sensible defaults that just work
+- **Modern Architecture** - Async/await throughout, no callback hell

-# TSPM Refactoring Plan: Central Daemon Architecture
+# TSPM Real-Time Log Streaming Implementation Plan

-## Problem Analysis
+## Overview
+Implementing real-time log streaming (tailing) functionality for TSPM using SmartIPC's pub/sub capabilities.

-Currently, each `startAsDaemon` creates an isolated tspm instance with no coordination:
+## Approach: Hybrid Request + Subscribe
+1. Initial getLogs request to fetch historical logs up to current point
+2. Subscribe to pub/sub channel for real-time updates  
+3. Use sequence numbers to detect and handle gaps/duplicates
+4. Per-process topics for granular subscriptions

- Multiple daemons reading/writing same config file
- No communication between instances
- Inconsistent process management
- `tspm list` shows all processes but each daemon only manages its own
+## Implementation Tasks

-## Proposed Architecture
+### Core Changes
+- [x] Update IProcessLog interface with seq and runId fields
+- [x] Add nextSeq and runId fields to ProcessWrapper class  
+- [x] Update addLog() methods to include sequencing
+- [x] Implement pub/sub publishing in daemon

-### 1. Central Daemon Manager (`ts/classes.daemon.ts`)
+### IPC Client Updates  
+- [x] Add subscribe/unsubscribe methods to TspmIpcClient
+- [ ] Implement log streaming handler
+- [ ] Add connection state management for subscriptions

- Single daemon instance managing ALL processes
- Runs continuously in background
- Uses Unix socket for IPC at `~/.tspm/tspm.sock`
- Maintains single source of truth for process state
+### CLI Enhancement
+- [x] Add --follow flag to logs command
+- [x] Implement streaming output with proper formatting
+- [x] Handle Ctrl+C gracefully to unsubscribe

-### 2. IPC Communication Layer (`ts/classes.ipc.ts`)
+### Reliability Features
+- [x] Add backpressure handling (drop oldest when buffer full)
+- [x] Implement gap detection and recovery
+- [x] Add process restart detection via runId

- **Framework**: Use `@push.rocks/smartipc` v2.0.1
- **Server**: SmartIpc server in daemon using Unix Domain Socket
- **Client**: SmartIpc client in CLI for all operations
- **Socket Path**: `~/.tspm/tspm.sock` (Unix) or named pipe (Windows)
- **Protocol**: Type-safe request/response with SmartIpc's built-in patterns
- **Features**:
-  - Automatic reconnection with exponential backoff
-  - Heartbeat monitoring for daemon health
-  - Type-safe message contracts
- **Auto-start**: CLI starts daemon if connection fails
-
-### 3. New CLI Commands
-
- `tspm enable` - Start central daemon using systemd/launchd
- `tspm disable` - Stop and disable central daemon
- `tspm status` - Show daemon status
- Remove `startAsDaemon` (replaced by daemon + `tspm start`)
-
-### 4. Refactored CLI (`ts/cli.ts`)
-
-All commands become daemon clients:
-
-```typescript
-// Before: Direct process management
-await tspm.start(config);
-
-// After: Send to daemon
-await ipcClient.request('start', config);
-```
-
-### 5. File Structure Changes
-
-```
-ts/
-├── classes.daemon.ts       # New: Central daemon server
-├── classes.ipc.ts          # New: IPC client/server
-├── classes.tspm.ts         # Modified: Used by daemon only
-├── cli.ts                  # Modified: Becomes thin client
-└── classes.daemonmanager.ts # New: Systemd/launchd integration
-```
-
-## Implementation Steps
-
-### Phase 1: Core Infrastructure
-
- [ ] Add `@push.rocks/smartipc` dependency (v2.0.1)
- [ ] Create IPC message type definitions for all operations
- [ ] Implement daemon server with SmartIpc server
- [ ] Create IPC client wrapper for CLI
- [ ] Add daemon lifecycle management (enable/disable)
-
-### Phase 2: CLI Refactoring
-
- [ ] Convert all CLI commands to SmartIpc client requests
- [ ] Add daemon auto-start logic with connection monitoring
- [ ] Leverage SmartIpc's built-in reconnection and error handling
- [ ] Implement type-safe message contracts for all commands
-
-### Phase 3: Migration & Cleanup
-
- [ ] Migrate existing config to daemon-compatible format
- [ ] Remove `startAsDaemon` command
- [ ] Add migration guide for users
+### Testing
+- [x] Test basic log streaming
+- [x] Test gap recovery
+- [x] Test high-volume logging scenarios  
+- [x] Test process restart handling

 ## Technical Details

-### IPC Implementation with SmartIpc
+### Sequence Numbering
+- Each log entry gets incrementing seq number per process
+- runId changes on process restart
+- Client tracks lastSeq to detect gaps

-```typescript
-// Daemon server setup
-import { SmartIpc } from '@push.rocks/smartipc';
+### Topic Structure
+- Format: `logs.<processId>`
+- Daemon publishes to topic on new log entries
+- Clients subscribe to specific process topics

-const ipcServer = SmartIpc.createServer({
-  id: 'tspm-daemon',
-  socketPath: '~/.tspm/tspm.sock', // Unix socket
-});
-
-// Message handlers with type safety
-ipcServer.onMessage<StartRequest, StartResponse>(
-  'start',
-  async (data, clientId) => {
-    const result = await tspmManager.start(data.config);
-    return { success: true, processId: result.pid };
-  },
-);
-
-// CLI client setup
-const ipcClient = SmartIpc.createClient({
-  id: 'tspm-daemon',
-  socketPath: '~/.tspm/tspm.sock',
-});
-
-// Type-safe requests
-const response = await ipcClient.request<StartRequest, StartResponse>('start', {
-  config: processConfig,
-});
-```
-
-### Message Types
-
-```typescript
-interface StartRequest {
-  config: ProcessConfig;
-}
-
-interface StartResponse {
-  success: boolean;
-  processId?: number;
-  error?: string;
-}
-```
-
-### Daemon State File
-
-`~/.tspm/daemon.state` - PID, socket path, version
-
-### Process Management
-
-Daemon maintains all ProcessMonitor instances internally, CLI never directly manages processes.
-
-## Key Benefits
-
-### Architecture Benefits
-
- Single daemon manages all processes
- Consistent state management
- Efficient resource usage
- Better process coordination
- Proper service integration with OS
-
-### SmartIpc Advantages
-
- **Cross-platform**: Unix sockets on Linux/macOS, named pipes on Windows
- **Type-safe**: Full TypeScript support with generic message types
- **Resilient**: Automatic reconnection with exponential backoff
- **Observable**: Built-in metrics and heartbeat monitoring
- **Performant**: Low-latency messaging with zero external dependencies
- **Secure**: Connection limits and message size restrictions
-
-## Backwards Compatibility
-
- Keep existing config format
- Auto-migrate on first run
- Provide clear upgrade instructions

-
-## Migration Path
-
-1. **Version 2.0.0-alpha**: Implement daemon with backwards compatibility
-2. **Version 2.0.0-beta**: Deprecate `startAsDaemon`, encourage daemon mode
-3. **Version 2.0.0**: Remove legacy code, daemon-only operation
-4. **Documentation**: Update all examples and guides
-
-## Security Considerations
-
- Unix socket permissions (user-only access)
- Validate all IPC messages
- Rate limiting for IPC requests
- Secure daemon shutdown mechanism
-
-## Testing Requirements
-
- Unit tests for IPC layer
- Integration tests for daemon lifecycle
- Migration tests from current architecture
- Performance tests for multiple processes
- Stress tests for IPC communication
+### Backpressure Strategy
+- Circular buffer of 10,000 entries per process
+- Drop oldest entries when buffer full
+- Client can detect gaps via sequence numbers
