Giving Renew() the default request timeout causes TestV3LeaseFailover
to miss its timing constraints. Since it only needs to wait until the
leader recognizes the leader is lost, use RequireLeader to cancel the
keepalive stream before the request times out.
Would retry a few times before returning a not primary error that
the client should never see. Instead, use proper timeouts and
then return a request timeout error on failure.
Fixes#6922
Using printf will try to parse the string and replace special
characters. In migrate code, we want to just output the raw
json string of client.Node.
For example,
Printf("%\\") => %!\(MISSING)
Print("%\\") => %\
Thus, we should use print instead.
Try:
./etcdctl put foo bar
./etcdctl del foo
./etcdctl compact 3
restart etcd
./etcdctl get foo
mvcc: required revision has been compacted
The error is unexpected when range over the head revision.
Internally, we incorrectly set current revision smaller than the
compacted revision when we remove all keys around compacted revision.
This commit fixes the issue by recovering the current revision at least
to compacted revision.
Most fields accessed with sync/atomic functions are 64bit aligned, but a couple
are not. This makes comments out of date and therefore misleading.
Affected fields reordered, comments scrubbed and updated.
The Entry struct has misaligned fields that are accessed atomically. The
misalignment is caused by the EntryType enum which the Protocol Buffers
spec forces to be a 32bit int.
Moving the order of the fields without renumbering them in the .proto file
seems to align the go structure without changing the wire format.
The relevant structures are properly aligned, however, there is no comment
highlighting the need to keep it aligned as is present elsewhere in the
codebase.
Adding note to keep alignment, in line with similar comments in the codebase.
