* fix(wdclient,volume): compare master leader with ServerAddress.Equals
Raft leader is advertised as host:httpPort.grpcPort, but clients dial
host:httpPort. Raw string comparison against VolumeLocation.Leader /
HeartbeatResponse.Leader therefore never matches, causing the
masterclient and the volume server heartbeat loop to continuously
"redirect" to the already-connected master, tearing down the stream
and reconnecting.
Use ServerAddress.Equals, which normalizes the grpc-port suffix.
* fix(filer,mq): compare ServerAddress via Equals in two more sites
filer bootstrap skip (MaybeBootstrapFromOnePeer) and the broker's local
partition assignment check both compared a wire-supplied address string
against the local self ServerAddress with raw string equality. Both are
vulnerable to the same plain-vs-host:port.grpcPort mismatch as the
masterclient/volume heartbeat sites: filer would bootstrap from itself,
and the broker would fail to claim a partition it was actually assigned.
Route both through ServerAddress.Equals.
* fix(master,shell): more ServerAddress comparisons via Equals
- raft_server_handlers.go HealthzHandler: s.serverAddr == leader would
skip the child-lock check on the real leader when the two carry
different plain/grpc-suffix forms, returning 200 OK instead of 423.
- master_server.go SetRaftServer leader-change callback: the
Leader() == Name() guard for ensureTopologyId could disagree with
topology.IsLeader() (which already uses Equals), so leader-only
initialization could be skipped after an election.
- command_volume_merge.go isReplicaServer: the -target guard compared
user-supplied host:port against NewServerAddressFromDataNode(...) with
==, letting an existing replica slip through when topology carries
the embedded gRPC port.
All routed through pb.ServerAddress.Equals.
* fix(mq,cluster): more ServerAddress comparisons via Equals
- broker_grpc_lookup.go GetTopicPublishers/GetTopicSubscribers: the
partition ownership check gated listing on raw
LeaderBroker == BrokerAddress().String(), so listings silently omitted
partitions hosted locally when the assignment carried the other
host:port / host:port.grpcPort form.
- lock_client.go: LockHostMovedTo comparison and the seedFiler fallback
guard both used raw string equality against configured filer
addresses (which may be plain host:port while LockHostMovedTo comes
back suffixed), causing spurious host-change churn and blocking the
seed-filer fallback.
* fix(mq): more ServerAddress comparisons via Equals
- pub_balancer/allocate.go EnsureAssignmentsToActiveBrokers: direct
activeBrokers.Get() lookup missed brokers when a persisted assignment
carried a different address encoding than the registered broker key,
triggering a bogus reassignment on every read/write cycle. Added a
findActiveBroker helper that falls back to an Equals-based scan and
canonicalizes the assignment in place so later writes are stable.
- broker_grpc_lookup.go isLockOwner: used raw string equality between
LockOwner() and BrokerAddress().String(), so a lock owner could fail
to recognize itself and proxy local lookup/config/admin RPCs away.
- pub_client/scheduler.go onEachAssignments: reused publisher jobs only
on exact LeaderBroker match, so an encoding flip in lookup results
tore down and recreated a stream to the same broker.
