Anton Kaliaev	4fc06e9d2a	[libs/pubsub] fix memory leak Refs #1755 I started with writing a test for wsConnection (WebsocketManager) where I: - create a WS connection - do a simple echo call - close it No leaking goroutines, nor any leaking memory were detected. For useful shortcuts see my blog post https://blog.cosmos.network/debugging-the-memory-leak-in-tendermint-210186711420 Then I went to the rpc tests to see if calling Subscribe results in memory growth. It did. I used a slightly modified version of TestHeaderEvents function: ``` func TestHeaderEvents(t testing.T) { // memory heap before f, err := os.Create("/tmp/mem1.mprof") if err != nil { t.Fatal(err) } pprof.WriteHeapProfile(f) f.Close() for i := 0; i < 100; i++ { c := getHTTPClient() err = c.Start() require.Nil(t, err) evtTyp := types.EventNewBlockHeader evt, err := client.WaitForOneEvent(c, evtTyp, waitForEventTimeout) require.Nil(t, err) _, ok := evt.(types.EventDataNewBlockHeader) require.True(t, ok) c.Stop() c = nil } runtime.GC() // memory heap before f, err = os.Create("/tmp/mem2.mprof") if err != nil { t.Fatal(err) } pprof.WriteHeapProfile(f) f.Close() // dump all running goroutines time.Sleep(10 time.Second) pprof.Lookup("goroutine").WriteTo(os.Stdout, 1) } ``` ``` Showing nodes accounting for 35159.16kB, 100% of 35159.16kB total Showing top 10 nodes out of 48 flat flat% sum% cum cum% 32022.23kB 91.08% 91.08% 32022.23kB 91.08% github.com/tendermint/tendermint/libs/pubsub/query.(QueryParser).Init 1056.33kB 3.00% 94.08% 1056.33kB 3.00% bufio.NewReaderSize 528.17kB 1.50% 95.58% 528.17kB 1.50% bufio.NewWriterSize 528.17kB 1.50% 97.09% 528.17kB 1.50% github.com/tendermint/tendermint/consensus.NewConsensusState 512.19kB 1.46% 98.54% 512.19kB 1.46% runtime.malg 512.08kB 1.46% 100% 512.08kB 1.46% syscall.ByteSliceFromString 0 0% 100% 512.08kB 1.46% github.com/tendermint/tendermint/consensus.(ConsensusState).(github.com/tendermint/tendermint/consensus.defaultDecideProposal)-fm 0 0% 100% 512.08kB 1.46% github.com/tendermint/tendermint/consensus.(ConsensusState).addVote 0 0% 100% 512.08kB 1.46% github.com/tendermint/tendermint/consensus.(ConsensusState).defaultDecideProposal 0 0% 100% 512.08kB 1.46% github.com/tendermint/tendermint/consensus.(ConsensusState).enterNewRound ``` 100 subscriptions produce 32MB. Again, no additional goroutines are running after the end of the test (wsConnection readRoutine and writeRoutine both finishes). It means that some exiting goroutine or object is holding a reference to the Query objects, which are leaking.** One of them is pubsub#loop. It's using state.queries to map queries to clients and state.clients to map clients to queries. Before this commit, we're not thoroughly cleaning state.queries, which was the reason for memory leakage.	6 years ago
