Preventing Resource Leaks in Go: How GoLand Helps You Write Safer Code
Resource leaks in Go occur when files, network connections, HTTP responses, or database resources aren't properly closed, leading to memory exhaustion and application failure. The article explains how Go's garbage collector can't prevent these leaks, demonstrates real-world examples of HTTP response body and SQL row leaks causing system crashes, and provides best practices like using defer statements and load testing. GoLand 2025.3 introduces resource leak analysis that detects unclosed resources across all execution paths in real-time, helping developers catch these subtle bugs during development before they reach production.
