Describe how you would use the GODEBUG environment variable for debugging purposes.

  • Set GODEBUG to "trace=1" to enable detailed tracing information for all packages.
  • Use GODEBUG to set specific flags for individual packages, allowing fine-grained debugging.
  • GODEBUG is not used for debugging purposes in Go.
  • Set GODEBUG to "verbose=1" to enable verbose output for the entire application.
The GODEBUG environment variable in Go allows fine-grained control over debugging output. You can set it to "gctrace=1" or "schedtrace=1000" to enable specific debug features for garbage collection or scheduler tracing, respectively. It's used to set flags for individual packages, enabling detailed debugging information for those packages while keeping others unaffected. The "trace=1" option enables detailed tracing information for all packages, but it's not the recommended approach for fine-grained debugging. GODEBUG is a powerful tool for debugging and understanding the behavior of specific Go components.
