Ferenc Szabo e38b227ce6 Ci race detector handle failing tests (#19143) ... * swarm/storage: increase mget timeout in common_test.go TestDbStoreCorrect_1k sometimes timed out with -race on Travis. --- FAIL: TestDbStoreCorrect_1k (24.63s) common_test.go:194: testStore failed: timed out after 10s * swarm: remove unused vars from TestSnapshotSyncWithServer nodeCount and chunkCount is returned from setupSim and those values we use. * swarm: move race/norace helpers from stream to testutil As we will need to use the flag in other packages, too. * swarm: refactor TestSwarmNetwork case Extract long running test cases for better visibility. * swarm/network: skip TestSyncingViaGlobalSync with -race As panics on Travis. panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x7e351b] * swarm: run TestSwarmNetwork with fewer nodes with -race As otherwise we always get test failure with `network_test.go:374: context deadline exceeded` even with raised `Timeout`. * swarm/network: run TestDeliveryFromNodes with fewer nodes with -race Test on Travis times out with 8 or more nodes if -race flag is present. * swarm/network: smaller node count for discovery tests with -race TestDiscoveryPersistenceSimulationSimAdapters failed on Travis with `-race` flag present. The failure was due to extensive memory usage, coming from the CGO runtime. Using a smaller node count resolves the issue. === RUN TestDiscoveryPersistenceSimulationSimAdapter ==7227==ERROR: ThreadSanitizer failed to allocate 0x80000 (524288) bytes of clock allocator (error code: 12) FATAL: ThreadSanitizer CHECK failed: ./gotsan.cc:6976 "((0 && "unable to mmap")) != (0)" (0x0, 0x0) FAIL github.com/ethereum/go-ethereum/swarm/network/simulations/discovery 804.826s * swarm/network: run TestFileRetrieval with fewer nodes with -race Otherwise we get a failure due to extensive memory usage, as the CGO runtime cannot allocate more bytes. === RUN TestFileRetrieval ==7366==ERROR: ThreadSanitizer failed to allocate 0x80000 (524288) bytes of clock allocator (error code: 12) FATAL: ThreadSanitizer CHECK failed: ./gotsan.cc:6976 "((0 && "unable to mmap")) != (0)" (0x0, 0x0) FAIL github.com/ethereum/go-ethereum/swarm/network/stream 155.165s * swarm/network: run TestRetrieval with fewer nodes with -race Otherwise we get a failure due to extensive memory usage, as the CGO runtime cannot allocate more bytes ("ThreadSanitizer failed to allocate"). * swarm/network: skip flaky TestGetSubscriptionsRPC on Travis w/ -race Test fails a lot with something like: streamer_test.go:1332: Real subscriptions and expected amount don't match; real: 0, expected: 20 * swarm/storage: skip TestDB_SubscribePull* tests on Travis w/ -race Travis just hangs... ok github.com/ethereum/go-ethereum/swarm/storage/feed/lookup 1.307s keepalive keepalive keepalive or panics after a while. Without these tests the race detector job is now stable. Let's invetigate these tests in a separate issue: https://github.com/ethersphere/go-ethereum/issues/1245		6 years ago
