The gopls daemon had different default logging behavior than the sidecar
gopls: by default, the daemon was started with -logfile=auto.
Additionally, because most logs are reflected back to the forwarder, the
actual daemon logs have very little (if any) information.
This means that if you simply start gopls with -remote=auto, you'll get
a single logfile named /tmp/gopls-<pid>.log, which is mostly empty. This
is not a delightful experience.
Fix this via several improvements:
+ Log lifecycle events in the Daemon, to give the log a purpose.
+ Give the daemon a new default log location:
/tmp/gopls-daemon-<pid>.log.
+ Don't pass -logfile=auto to the daemon by default.
