Currently many more Python projects like dask and optuna are using Python type hints. With the Python package of xgboost gaining more and more features, we should also adopt mypy as a safe guard against some type errors and for better code documentation.

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

However, this seems not be documented. For instance, scaladoc/javadoc of pipeToSelf could mention it as well as any other place where adapters are used.

Let's support at least reading "b3" header from a single string, most commonly traceid-spanid-1
It would also be nice to support optionally writing this, especially in message providers or others with constrained environments.

Expected behavior

As discussed on openzipkin/b3-propagation#21 and first implemented here: https://github.com/openzipkin/brave/blob/master/brave/src/main/java/bra

Hello Philip!
I think there is an issue with this part of the code of rqlite (store/store.go).

	if leader && s.raft.State() != raft.Leader {
		return nil, ErrNotLeader
	}

	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

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:
