Today, etcdctl endpoint health only performs a quorum GET. If server is corrupted or exceeded quota (which put the server into read only mode), this command incorrectly returns healthy.

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

func (s *Store) Database(leader bool) ([]byte, error) {
	if leader && s.raft.State() != raft.Leader {
		return nil, ErrNotLeader
	}
	// 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-

Quorum doesn't return a message error clearly specifying the cause of an error (from a user standpoint) when the transaction manager fails to Quorum (e.g: 400 bad request, ...).

The blockchain v2 reactor utilizes concurrency to saturate the bottleneck of writing blocks to disk. This concurrency is internal to the reactor where the reactor itself will launch and manage internal state machines running as go-routines. This configuration makes testing difficult as we don't know when messages processed by internal state machines will be processed and when we can assert that th

Here is a rough idea of what this test should do:

• It should isolate a follower node, write a data to the cluster which will cause that node to fall behind into lagging state, but not into snapshotting state.
• It should then spawn a task which will continue to write data to the cluster.
• Just after it is spawne

Description

We need a short version of our full unit test suite that doesn't take too long to run, and that passes on all supported operating systems (linux, macos, windows, freebsd) without needing a special ulimit env. This will also be useful for running against the other operating systems in CI (see #2060).

Right now, I cannot even run the full unit test suite locally on my Mac, even wi

Instead of a single validator (a.k.a. pivot node), the test net_dynamic_hb should pick a subset of validators at random for removal. This will better reflect the [interface](https://github.com/poanetwork/hbbft/blob/742ad7b83a3f613fd9a7b4ff88cfa82b10bd7dd3/src/dynamic_honey_badger/dyn
