Go Concurrency Patterns
Production patterns for Go concurrency including goroutines, channels, synchronization primitives, and context management.
When to Use This Skill
- Building concurrent Go applications
- Implementing worker pools and pipelines
- Managing goroutine lifecycles
- Using channels for communication
- Debugging race conditions
- Implementing graceful shutdown
Core Concepts
1. Go Concurrency Primitives
| Primitive | Purpose |
|---|---|
goroutine | Lightweight concurrent execution |
channel | Communication between goroutines |
select | Multiplex channel operations |
sync.Mutex | Mutual exclusion |
sync.WaitGroup | Wait for goroutines to complete |
context.Context | Cancellation and deadlines |
2. Go Concurrency Mantra
Don't communicate by sharing memory;
share memory by communicating.
Quick Start
package main
import (
"context"
"fmt"
"sync"
"time"
)
func main() {
ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()
results := make(chan string, 10)
var wg sync.WaitGroup
// Spawn workers
for i := 0; i < 3; i++ {
wg.Add(1)
go worker(ctx, i, results, &wg)
}
// Close results when done
go func() {
wg.Wait()
close(results)
}()
// Collect re

# Memory Safety Patterns
Cross-language patterns for memory-safe programming including RAII, ownership, smart pointers, and resource management.
## When to Use This Skill
- Writing memory-safe systems code
- Managing resources (files, sockets, memory)
- Preventing use-after-free and leaks
- Implementing RAII patterns
- Choosing between languages for safety
- Debugging memory issues
## Core Concepts
### 1. Memory Bug Categories
| Bug Type | Description | Prevention |
| -------------------- | -------------------------------- | ----------------- |
| **Use-after-free** | Access freed memory | Ownership, RAII |
| **Double-free** | Free same memory twice | Smart pointers |
| **Memory leak** | Never free memory | RAII, GC |
| **Buffer overflow** | Write past buffer end | Bounds checking |
| **Dangling pointer** | Pointer to freed memory | Lifetime tracking |
| **Data race** | Concurrent unsynchronized access | Ownership, Sync |
### 2. Safety Spectrum
Manual (C) → Smart Pointers (C++) → Ownership (Rust) → GC (Go, Java) Less safe More safe More control Less control
## Patterns by Language
### Pattern 1: RAII in C++
```cpp
// RAII: Resource Acquisition Is Initialization
// Resource lifetime tied to object lifetime
#include <memory>
#include <fstre

# Rust Async Patterns
Production patterns for async Rust programming with Tokio runtime, including tasks, channels, streams, and error handling.
## When to Use This Skill
- Building async Rust applications
- Implementing concurrent network services
- Using Tokio for async I/O
- Handling async errors properly
- Debugging async code issues
- Optimizing async performance
## Core Concepts
### 1. Async Execution Model
Future (lazy) → poll() → Ready(value) | Pending ↑ ↓ Waker ← Runtime schedules
### 2. Key Abstractions
| Concept | Purpose |
| ---------- | ---------------------------------------- |
| `Future` | Lazy computation that may complete later |
| `async fn` | Function returning impl Future |
| `await` | Suspend until future completes |
| `Task` | Spawned future running concurrently |
| `Runtime` | Executor that polls futures |
## Quick Start
```toml
# Cargo.toml
[dependencies]
tokio = { version = "1", features = ["full"] }
futures = "0.3"
async-trait = "0.1"
anyhow = "1.0"
tracing = "0.1"
tracing-subscriber = "0.3"
use tokio::time::{sleep, Duration};
use anyhow::Result;
#[tokio::main]
async fn main() -> Result<()> {
// Initialize tracing
tracing_subscriber::fmt::init();
// Async operations
let result = fetch_data("https://api.example.com").await?;
println!("Got: {}", result);
Ok(())
}
async fn
