Downstream users of etcd experience build issues when using dependencies
which require more recent (incompatible) versions of opentelemetry. This
commit upgrades the dependencies so that downstream users stop
experiencing these issues.
The first issue is to support linearizable lease renewal request.
The second issue is to prevent the consistent_index coming from
a snapshot is overwritten by the local old value.
Update raftexample to save the snapshot file and WAL snapshot entry
before hardstate to ensure the snapshot exists during recovery.
Otherwise if there is a failure after storing the hard state there may
be reference to a non-existent snapshot.
This PR introduces the fix from #10219 to the raftexample.
When a user sets up a Mirror with a restricted user that doesn't have
access to the `foo` path, we will fail to get the most recent revision
due to permissions issues.
With this change, when a prefix is provided we will get the initial
revision from the prefix rather than /foo. This allows restricted users
to setup sync.
When etcdserver receives a LeaseRenew request, it may be still in
progress of processing the LeaseGrantRequest on exact the same
leaseID. Accordingly it may return a TTL=0 to client due to the
leaseID not found error. So the leader should wait for the appliedID
to be available before processing client requests.
humanize.Time() drops precision resulting in some events reporting they took
"now" time to complete. Using time.Duration.String() results in accurate
duration being reported.
Fixes#13905
Reason to store CI and term in backend was to make db fully independent
snapshot, it was never meant to interfere with apply logic. Skip of CI
was introduced for v2->v3 migration where we wanted to prevent it from
decreasing when replaying wal in
https://github.com/etcd-io/etcd/pull/5391. By mistake it was added to
apply flow during refactor in
https://github.com/etcd-io/etcd/pull/12855#commitcomment-70713670.
Consistency index and term should only be negotiated and used by raft to make
decisions. Their values should only driven by raft state machine and
backend should only be responsible for storing them.
Currently there are a handful of tests within etcd that silently fail
because LeakDetection will skip the test before it manages to hit this
check.
Here we move the check to the beginning of the process to highlight
these cases earlier, and to avoid them accidentally presenting as leaks.
Removed the fields consistentIdx and consistentTerm from struct EtcdServer,
and added applyingIndex and applyingTerm into struct consistentIndex in
package cindex. We may remove the two fields completely if we decide to
remove the OnPreCommitUnsafe, and it will depend on the performance test
result.
