Description

currently we ask users to supply flags such as -port and -rpc.trace and restart gopls when debugging is needed. Please consider turning on the debug port by default and make some traces available.

  • Port number needs to be picked up randomly - so we will need a way for the client to ask gopls about the debug port location.
  • May need too allow opt-out.

Contributor guide

Research direction
Implement automatic debug port allocation and opt out in gopls. The debug server should be started with a random port, and the client should be able to query the port. Provide a way to opt out (e.g., via flag).
