It is mentioned that there is an error code page for v2 protocol:
https://github.com/etcd-io/etcd/blob/ae7862e8bc8007eb396099db4e0e04ac026c8df5/server/etcdserver/api/v2error/error.go#L16

Note to new contributors: Post a comment here if you'd like to work on this issue. Feel free to ping me for help.

ActorAdapter will ignore null message with "Adapter function returned null which is not valid as an .."

	}
	// Ensure only one snapshot can take place at once, and block all queries.
	s.mu.Lock()
	defer s.mu.Unlock()

	f, err := ioutil.TempFile("", "rqlilte-snap-

Cobra, the library used to implement the CLI commands also generate the shell completion scripts, for bash, zsh, fish and powershell. This completion scripts are based on the description of each commands (living in https://github.com/MichaelMure/git-bug/tree/master/commands).

At the moment, those completion works decently, completing command names and flags. However it would be possible to do b

Is your feature request related to a problem? Please describe.
Using Reset command with CLI will get code:deadline-exceeded message:timeout easily because reset requires replay in the server. It's quite resource consuming, depending on the length/size of the history.

By default the CLI context timeout is only 5 seconds:
