Erik Grinaker b9a0d47f14 test/blockchain/v0: mitigate test data race (#4886 ) Mitigates the below data race. The proper fix involves not fiddling with reactor internals, which needs a rewrite of the test and possible additional reactor infrastructure. ``` ================== WARNING: DATA RACE Write at 0x00c001118e78 by goroutine 187: github.com/tendermint/tendermint/blockchain/v0.TestBadBlockStopsPeer() /go/src/github.com/tendermint/tendermint/blockchain/v0/reactor_test.go:234 +0x9d7 testing.tRunner() /usr/local/go/src/testing/testing.go:992 +0x1eb Previous read at 0x00c001118e78 by goroutine 326: [failed to restore the stack] Goroutine 187 (running) created at: testing.(T).Run() /usr/local/go/src/testing/testing.go:1043 +0x660 testing.runTests.func1() /usr/local/go/src/testing/testing.go:1285 +0xa6 testing.tRunner() /usr/local/go/src/testing/testing.go:992 +0x1eb testing.runTests() /usr/local/go/src/testing/testing.go:1283 +0x527 testing.(M).Run() /usr/local/go/src/testing/testing.go:1200 +0x2ff main.main() _testmain.go:112 +0x337 Goroutine 326 (running) created at: github.com/tendermint/tendermint/blockchain/v0.(BlockchainReactor).OnStart() /go/src/github.com/tendermint/tendermint/blockchain/v0/reactor.go:118 +0x12c github.com/tendermint/tendermint/libs/service.(BaseService).Start() /go/src/github.com/tendermint/tendermint/libs/service/service.go:140 +0x504 github.com/tendermint/tendermint/blockchain/v0.(BlockchainReactor).Start() <autogenerated>:1 +0x43 github.com/tendermint/tendermint/p2p.(Switch).OnStart() /go/src/github.com/tendermint/tendermint/p2p/switch.go:225 +0x120 github.com/tendermint/tendermint/libs/service.(BaseService).Start() /go/src/github.com/tendermint/tendermint/libs/service/service.go:140 +0x504 github.com/tendermint/tendermint/p2p.StartSwitches() /go/src/github.com/tendermint/tendermint/p2p/test_util.go:168 +0x75 github.com/tendermint/tendermint/p2p.MakeConnectedSwitches() /go/src/github.com/tendermint/tendermint/p2p/test_util.go:89 +0x17d github.com/tendermint/tendermint/blockchain/v0.TestBadBlockStopsPeer() /go/src/github.com/tendermint/tendermint/blockchain/v0/reactor_test.go:209 +0x768 testing.tRunner() /usr/local/go/src/testing/testing.go:992 +0x1eb ================== panic: BlockStore can only save contiguous blocks.
