same question

return } log.VEventf(ctx, 1, "enabled v2 protocol using v1 priority encoding")
did you want this to be traced, or was the intention to do:
if log.V(1) {
log.Infof(...)
}
Also, would the RangeID or the start key of the range be helpful?

Same as below, the rangeID isn't always included here in the ctx tags, so I added it.

I don't mind this being traced, otherwise we could just do VInfo. The RangeID is included via the range tag attached to the context by the raft scheduler.

130728: kvserver: add rac2 v1 integration tests r=sumeerbhola a=kvoli 1st commit from #130619. 2nd-3rd commits from #131106. 4th-5th commits from #131107. 6th-7th commits from #131108. 8th commit from #131109. --- Introduce several tests in `flow_control_integration_test.go`, mirroring the existing tests but applied to the replication flow control v2 machinery. The tests largely follow an identical pattern to the existing v1 tests, swapping in rac2 metrics and vtables. The following tests are added: ``` TestFlowControlBasicV2 TestFlowControlRangeSplitMergeV2 TestFlowControlBlockedAdmissionV2 TestFlowControlAdmissionPostSplitMergeV2 TestFlowControlCrashedNodeV2 TestFlowControlRaftSnapshotV2 TestFlowControlRaftMembershipV2 TestFlowControlRaftMembershipRemoveSelfV2 TestFlowControlClassPrioritizationV2 TestFlowControlQuiescedRangeV2 TestFlowControlUnquiescedRangeV2 TestFlowControlTransferLeaseV2 TestFlowControlLeaderNotLeaseholderV2 TestFlowControlGranterAdmitOneByOneV2 ``` These tests all have at least two variants: ``` V2EnabledWhenLeaderV1Encoding V2EnabledWhenLeaderV2Encoding ``` When `V2EnabledWhenLeaderV1Encoding` is run, the tests use a different testdata file, which has a `_v1_encoding` suffix. A separate file is necessary because when the protocol enablement level is `V2EnabledWhenLeaderV1Encoding`, all entries which are subject to admission control are encoded as `raftpb.LowPri`, regardless of their original priority, as we don't want to pay the cost to deserialize the raft admission meta. The v1 encoding variants retain the same comments as the v2 encoding, however any comments referring to regular tokens should be interpreted as elastic tokens instead, due to the above. Two v1 tests are not ported over to v2: ``` TestFlowControlRaftTransportBreak TestFlowControlRaftTransportCulled ``` These omitted tests behave identically to `TestFlowControlCrashedNodeV2` as rac2 is less tightly coupled to the raft transport, instead operating on replication states (e.g., `StateProbe`, `StateReplicate`). --- Add `TestFlowControlV1ToV2Transition`, which ratchets up the enabled version of replication flow control v2: ``` v1 protocol with v1 encoding => v2 protocol with v1 encoding => v2 protocol with v2 encoding ``` The test is structured to issue writes and wait for returned tokens whenever the protocol transitions from v1 to v2, or a leader changes. More specifically, the test takes the following steps: ``` (1) Start n1, n2, n3 with v1 protocol and v1 encoding. (2) Upgrade n1 to v2 protocol with v1 encoding. (3) Transfer the range lease to n2. (4) Upgrade n2 to v2 protocol with v1 encoding. (5) Upgrade n3 to v2 protocol with v1 encoding. (6) Upgrade n1 to v2 protocol with v2 encoding. (7) Transfer the range lease to n1. (8) Upgrade n2,n3 to v2 protocol with v2 encoding. (9) Transfer the range lease to n3. ``` Between each step, we issue writes, (un)block admission and observe the flow control metrics and vtables. Resolves: #130431 Resolves: #129276 Release note: None 131252: roachtest: port decommission/mixed-versions r=srosenberg,DarrylWong a=renatolabs This commit ports the `decommission/mixed-versions` roachtest to use the `mixedversion` framework (instead of the old `newUpgradeTest` API). It also updates `acceptance/decommission-self` since both tests used shared functionality that needed to be updated. Prior to this commit, the acceptance test used the old upgrade test API even though it was not an upgrade test.
