client: Move client specific code (protos, version) to the api/
directory. Thanks to this change /client directory will not need to depend on
the server code. In next commits we make "/api" a module on its own.
Mechanical consequences of execution:
% git mv version/version.go api/version
% git mv etcdserver/api/v3rpc/rpctypes api/v3rpc
% git mv mvcc/mvccpb api/
% git mv etcdserver/etcdserverpb api/
% git mv auth/authpb api/
% git mv etcdserver/api/membership/membershippb api/
To improve debuggability of `agreement among raft nodes before
linearized reading`, we added some tracing inside
`linearizableReadLoop`.
This will allow us to know the timing of `s.r.ReadIndex` vs
`s.applyWait.Wait(rs.Index)`.
* etcdserver: check authinfo if it is not InternalAuthenticateRequest.
* credentials: let GetRequestMetadata() return nil when authToken isn't initialized.
* clientv3: get AuthToken gracefully without extra connection.
The code used to:
- report time since previous compaction success as a 'duration' of compaction process itself.
- mix real clock with 'injected' clock. This led to strange log-lines
in tests in order of 234543543h of duration.
To fix a panic that happens when trying to get ids of etcd members in
force new cluster mode, the issue happen if the cluster previously had
etcd learner nodes added to the cluster
Fixes#12285
Similar counts are exposed via Prometheus.
This adds the one that are perceived by etcd server.
e.g.
os_fd_limit 120000
os_fd_used 14
process_cpu_seconds_total 0.31
process_max_fds 120000
process_open_fds 17

This ticker will check File Descriptor Requirements ,and count all fds in used.
And recorded some logs when in used >= limit/5*4. Just recorded message.
If fds was more than 10K,It's low performance due to FDUsage() works.
So need to increase it.
see https://github.com/etcd-io/etcd/issues/11969 for more detail.
