```

The schedule for compact is handled asynchronously and it might use
`t.Logf` after go-test marks the case is done. And there is a comment
from go-test:

```go
// c69ff3a7d0/src/testing/testing.go (LL1580C3-L1582C16)
                // Do not lock t.done to allow race detector to detect race in case
		// the user does not appropriately synchronize a goroutine.
		t.done = true
```

We need to ensure that all the goroutines should be closed before case
finish.

etcdserver: fix corruption check when server has just been compacted

cc1e245368 etcdserver: fix corruption check when server has just been compacted 
When a key-value store corruption check happens immediately after a
compaction, the revision at which the key-value store hash is computed,
is the compacted revision itself.
In that case, the hash computation logic was incorrect because it
returned an ErrCompacted error; this error should instead be returned when
the revision at which the key-value store is hashed, is strictly lower
than the compacted revision.

Fixes #14325

bfd5170f66 add a txPostLockHook into the backend 
Previously the SetConsistentIndex() is called during the apply workflow,
but it's outside the db transaction. If a commit happens between SetConsistentIndex
and the following apply workflow, and etcd crashes for whatever reason right
after the commit, then etcd commits an incomplete transaction to db.
Eventually etcd runs into the data inconsistency issue.

In this commit, we move the SetConsistentIndex into a txPostLockHook, so
it will be executed inside the transaction lock.
