Go Memory Leak Demo ​

🚧 Coming Soon - This demo is under development

Overview ​

The Go demo will showcase memory leak detection and prevention techniques specific to Go applications, including:

Planned Features ​

Common Go Memory Leak Patterns ​

  • Goroutine Leaks: Goroutines that never terminate
  • Channel Leaks: Channels not properly closed
  • Slice/Map Growth: Growing slices and maps without bounds
  • HTTP Client Leaks: HTTP connections not properly closed
  • Context Leaks: Context objects not canceled
  • Finalizer Leaks: Objects with finalizers not being collected

Demo Application ​

  • Gin or Echo HTTP server with leak simulation endpoints
  • pprof integration for profiling
  • Memory and goroutine monitoring
  • Benchmarking tools for performance testing

Technologies ​

  • Framework: Gin or Echo
  • Profiling: pprof, go tool trace
  • Monitoring: Prometheus metrics
  • Testing: Go standard testing, testify

Quick Start (When Available) ​

bash
cd go/gin-demo
go mod tidy
go run main.go

Go-Specific Tools ​

Built-in Profiling ​

bash
# CPU profiling
go tool pprof http://localhost:8080/debug/pprof/profile

# Memory profiling
go tool pprof http://localhost:8080/debug/pprof/heap

# Goroutine profiling
go tool pprof http://localhost:8080/debug/pprof/goroutine

Memory Analysis ​

bash
# Memory stats
go tool pprof -http=:8081 http://localhost:8080/debug/pprof/heap

# Goroutine analysis
go tool pprof -http=:8081 http://localhost:8080/debug/pprof/goroutine
