It will now chain connection and transaction completion stages correctly. Previously it tried to check connection and transaction for null, which was unsafe because it was not properly chained with subsequent async operations. `ExplicitTransaction` now tracks it's state more thoroughly and does not allow running queries after commit & rollback. Also fixed couple tests after sync over async. --- .../org/neo4j/driver/internal/Bookmark.java | 23 ++ .../driver/internal/ExplicitTransaction.java | 53 ++-- .../neo4j/driver/internal/NetworkSession.java | 187 ++++++----- .../driver/internal/async/QueryRunner.java | 6 +- .../internal/packstream/PackOutput.java | 1 + .../driver/internal/DriverFactoryTest.java | 2 +- .../internal/ExplicitTransactionTest.java | 22 +- .../driver/internal/InternalDriverTest.java | 3 +- .../internal/InternalStatementResultTest.java | 2 +- .../driver/internal/NetworkSessionTest.java | 300 ++++++++++++++---- .../internal/RoutingDriverBoltKitTest.java | 35 +- .../internal/cluster/RediscoveryTest.java | 4 +- .../MemorizingInboundMessageDispatcher.java | 105 ++++++ .../internal/messaging/MessageFormatTest.java | 55 ++-- .../ExponentialBackoffRetryLogicTest.java | 4 +- .../internal/retry/FixedRetryLogic.java | 7 +- ... => ImmediateSchedulingEventExecutor.java} | 6 +- .../driver/v1/integration/SessionAsyncIT.java | 74 ++++- .../driver/v1/stress/AsyncFailingQuery.java | 3 +- .../v1/stress/AsyncFailingQueryInTx.java | 3 +- .../driver/v1/stress/AsyncWriteQuery.java | 3 +- .../driver/v1/stress/AsyncWriteQueryInTx.java | 3 +- .../driver/v1/stress/AsyncWrongQuery.java | 3 +- .../driver/v1/stress/AsyncWrongQueryInTx.java | 3 +- .../org/neo4j/driver/v1/util/TestUtil.java | 26 ++ 25 files changed, 665 insertions(+), 268 deletions(-) create mode 100644 driver/src/test/java/org/neo4j/driver/internal/messaging/MemorizingInboundMessageDispatcher.java rename driver/src/test/java/org/neo4j/driver/internal/util/{TrackingEventExecutor.java => ImmediateSchedulingEventExecutor.java} (97%) diff --git a/driver/src/main/java/org/neo4j/driver/internal/Bookmark.java b/driver/src/main/java/org/neo4j/driver/internal/Bookmark.java index a7729f15dc..4c88203999 100644 --- a/driver/src/main/java/org/neo4j/driver/internal/Bookmark.java +++ b/driver/src/main/java/org/neo4j/driver/internal/Bookmark.java @@ -22,6 +22,7 @@ import java.util.HashMap;

For each chunk it first reserves two bytes for headers, then writes chunk body and then comes back to the beginning to white actual size. Initially first reserved two bytes contain zeroes. Previously output tried to "skip" two first header bytes by advancing current writer index by two. This worked for most cases but failed when current writer index was at buffers capacity. Advancing writer index beyond the buffer capacity does not extend the buffer but causes an exception. This commit fixes the problem by making output actually write two zero bytes, which expands buffer capacity, when necessary. --- .../driver/internal/async/ProtocolUtil.java | 7 ++++ .../outbound/ChunkAwareByteBufOutput.java | 3 +- .../outbound/ChunkAwareByteBufOutputTest.java | 41 ++++++++++--------- 3 files changed, 30 insertions(+), 21 deletions(-) diff --git a/driver/src/main/java/org/neo4j/driver/internal/async/ProtocolUtil.java b/driver/src/main/java/org/neo4j/driver/internal/async/ProtocolUtil.java index d69016937c..c0a8569c5c 100644 --- a/driver/src/main/java/org/neo4j/driver/internal/async/ProtocolUtil.java +++ b/driver/src/main/java/org/neo4j/driver/internal/async/ProtocolUtil.java @@ -45,6 +45,8 @@ public final class ProtocolUtil private static final ByteBuf MESSAGE_BOUNDARY_BUF = unreleasableBuffer( copyShort( 0 ) ).asReadOnly();

this is needed to throw pretty errors when TLS handshake fails because of wrong certificates, etc. * `InternalStatementResultCursor` now throws with different messages based on the mode it's use in; this is needed to throw correct errors when it's used by blocking `StatementResult` * introduced a way for session to track latest result and await for it being finished (either fully received of failed); this is needed to guarantee that `Session#close()` does not RESET previous unconsumed queries The only ignored tests right now are for `Session#reset()`. They will be fixed subsequent commits. Also many TODOs were added. They will also be addressed later. --- .../driver/internal/ExplicitTransaction.java | 4 +- .../neo4j/driver/internal/NetworkSession.java | 57 ++++++- .../async/HandshakeResponseHandler.java | 24 ++- .../async/InternalStatementResultCursor.java | 60 ++++---- .../internal/async/NettyConnection.java | 1 - .../driver/internal/async/QueryRunner.java | 37 +++-- .../async/inbound/InboundMessageHandler.java | 7 + .../outbound/OutboundMessageHandler.java | 6 + .../internal/async/pool/NettyChannelPool.java | 4 +- .../driver/internal/cluster/Rediscovery.java | 2 + .../cluster/RoutingProcedureRunner.java | 2 +- .../handlers/PullAllResponseHandler.java | 139 ++++++++++++++---- .../internal/InternalStatementResultTest.java | 4 +- .../driver/internal/NetworkSessionTest.java | 3 +- .../async/HandshakeResponseHandlerTest.java | 6 + .../util/ChannelTrackingDriverFactory.java | 20 ++- .../internal/util/DriverFactoryWithClock.java | 1 - .../v1/integration/CausalClusteringIT.java | 2 +- .../v1/integration/ConnectionHandlingIT.java | 28 ++-- .../v1/integration/ConnectionPoolIT.java | 93 +++++++----- .../driver/v1/integration/LoggingIT.java | 6 +- .../driver/v1/integration/ResultStreamIT.java | 21 +++ .../driver/v1/integration/ServerKilledIT.java | 5 - .../driver/v1/integration/SessionIT.java | 9 ++ .../driver/v1/integration/TransactionIT.java | 4 +- .../neo4j/driver/v1/tck/DriverAuthSteps.java | 51 ++++--- .../resources/non_discovery_server.script | 3 +- 27 files changed, 430 insertions(+), 169 deletions(-) diff --git a/driver/src/main/java/org/neo4j/driver/internal/ExplicitTransaction.java b/driver/src/main/java/org/neo4j/driver/internal/ExplicitTransaction.java index 22334ef753..56f4a7c86c 100644 --- a/driver/src/main/java/org/neo4j/driver/internal/ExplicitTransaction.java +++ b/driver/src/main/java/org/neo4j/driver/internal/ExplicitTransaction.java @@ -272,7 +272,7 @@ public CompletionStage runAsync( String statementTemplate public StatementResult run( Statement statement ) { ensureCanRunQueries(); - StatementResultCursor cursor = getBlocking( QueryRunner.runSync( connection, statement, this ) ); + StatementResultCursor cursor = getBlocking( QueryRunner.runAsBlocking( connection, statement, this ) ); return new InternalStatementResult( cursor ); } @@ -280,7 +280,7 @@ public StatementResult run( Statement statement ) public CompletionStage runAsync( Statement statement ) { ensureCanRunQueries(); - return QueryRunner.runAsync( connection, statement, this ); + return (CompletionStage) QueryRunner.runAsAsync( connection, statement, this ); } @Override diff --git a/driver/src/main/java/org/neo4j/driver/internal/NetworkSession.java b/driver/src/main/java/org/neo4j/driver/internal/NetworkSession.java index b64e263e22..302c90ff4c 100644 --- a/driver/src/main/java/org/neo4j/driver/internal/NetworkSession.java +++ b/driver/src/main/java/org/neo4j/driver/internal/NetworkSession.java @@ -20,11 +20,13 @@ import java.util.Map; import java.util.concurrent.CompletableFuture; +import java.util.concurrent.CompletionException; import java.util.concurrent.CompletionStage; import java.util.concurrent.atomic.AtomicBoolean; import org.neo4j.driver.internal.async.AsyncConnection; import org.neo4j.driver.internal.async.Futures; +import org.neo4j.driver.internal.async.InternalStatementResultCursor; import org.neo4j.driver.internal.async.QueryRunner; import org.neo4j.driver.internal.logging.DelegatingLogger; import org.neo4j.driver.internal.retry.RetryLogic; @@ -62,6 +64,7 @@ public class NetworkSession implements Session private volatile Bookmark bookmark = Bookmark.empty(); private volatile CompletionStage transactionStage = completedFuture( null ); private volatile CompletionStage connectionStage = completedFuture( null ); + private volatile CompletionStage lastResultStage = completedFuture( null ); private final AtomicBoolean open = new AtomicBoolean( true ); @@ -137,7 +140,8 @@ public StatementResult run( Statement statement ) @Override public CompletionStage runAsync( Statement statement ) { - return runAsync( statement, true ); + //noinspection unchecked + return (CompletionStage) runAsync( statement, true ); } @Override @@ -149,12 +153,28 @@ public boolean isOpen() @Override public void close() { - getBlocking( closeAsync() ); + if ( open.compareAndSet( true, false ) ) + { + // todo: should closeAsync() also do this waiting for buffered result?
