Question 1

How do I set up godbg for remote debugging?

Accepted Answer

Generate SSL/TLS certificates using Go's generate_cert.go script, set environment variables for host and certificate paths, and ensure file permissions are secure. Then launch godbg to access the session via a magic URL in your browser.

Question 2

Godbg vs command-line gdb: which is better for Go debugging?

Accepted Answer

Godbg is better if you prefer a visual interface and remote access, but command-line gdb is more reliable for complex setups since it avoids godbg's compatibility issues with newer gdb versions and Go runtime quirks.

Question 3

Why does my godbg session freeze with high CPU usage?

Accepted Answer

This is often due to the Go string pretty-printer in runtime-gdb.py attempting to parse uninitialized strings. You need to modify the script's to_string() method to handle large or invalid lengths, as described in the README.

Question 4

How to fix gdb codesigning errors on Mac for godbg?

Accepted Answer

Create a self-signed code signing certificate in Keychain Access, set it to always trust, restart your computer, and use the codesign command to sign the gdb binary, as detailed in the Mac codesigning section.

Question 5

Does godbg support the latest version of gdb?

Accepted Answer

No, godbg is explicitly tested with gdb 7.5 and 7.6 only. Newer gdb versions may not work due to changes in the MI interface, and the README does not provide updates for compatibility.

Question 6

How to generate SSL certificates for godbg?

Accepted Answer

Use the Go script at crypto/tls/generate_cert.go with the -ca and -host flags, then secure the cert.pem and key.pem files with chmod to prevent unauthorized access, as outlined in the remote access instructions.
