N1QL support

Open EdgarLGB opened this issue 6 years ago • 0 comments

Hi,

I'm using the CouchbaseMock to do the unit test where a Couchbase client will send a N1QL query to the mock server. But it turns out that the client cannot decode the result which is null.

Here is my N1QL query:

SELECT * FROM scientists``

And here is the trace:

java.lang.IndexOutOfBoundsException: readerIndex(0) + length(1) exceeds writerIndex(0): PooledUnsafeDirectByteBuf(ridx: 0, widx: 0, cap: 256) com.couchbase.client.core.CouchbaseException: java.lang.IndexOutOfBoundsException: readerIndex(0) + length(1) exceeds writerIndex(0): PooledUnsafeDirectByteBuf(ridx: 0, widx: 0, cap: 256) at com.couchbase.client.core.endpoint.AbstractGenericHandler.decode(AbstractGenericHandler.java:369) at com.couchbase.client.deps.io.netty.handler.codec.MessageToMessageCodec$2.decode(MessageToMessageCodec.java:81) at com.couchbase.client.deps.io.netty.handler.codec.MessageToMessageDecoder.channelRead(MessageToMessageDecoder.java:88) at com.couchbase.client.deps.io.netty.handler.codec.MessageToMessageCodec.channelRead(MessageToMessageCodec.java:111) at com.couchbase.client.deps.io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:356) at com.couchbase.client.deps.io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:342) at com.couchbase.client.deps.io.netty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:335) at com.couchbase.client.deps.io.netty.channel.CombinedChannelDuplexHandler$DelegatingChannelHandlerContext.fireChannelRead(CombinedChannelDuplexHandler.java:438) at com.couchbase.client.deps.io.netty.handler.codec.ByteToMessageDecoder.fireChannelRead(ByteToMessageDecoder.java:312) at com.couchbase.client.deps.io.netty.handler.codec.ByteToMessageDecoder.channelRead(ByteToMessageDecoder.java:286) at com.couchbase.client.deps.io.netty.channel.CombinedChannelDuplexHandler.channelRead(CombinedChannelDuplexHandler.java:253) at com.couchbase.client.deps.io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:356) at com.couchbase.client.deps.io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:342) at com.couchbase.client.deps.io.netty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:335) at com.couchbase.client.deps.io.netty.handler.timeout.IdleStateHandler.channelRead(IdleStateHandler.java:286) at com.couchbase.client.deps.io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:356) at com.couchbase.client.deps.io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:342) at com.couchbase.client.deps.io.netty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:335) at com.couchbase.client.deps.io.netty.channel.DefaultChannelPipeline$HeadContext.channelRead(DefaultChannelPipeline.java:1304) at com.couchbase.client.deps.io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:356) at com.couchbase.client.deps.io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:342) at com.couchbase.client.deps.io.netty.channel.DefaultChannelPipeline.fireChannelRead(DefaultChannelPipeline.java:921) at com.couchbase.client.deps.io.netty.channel.nio.AbstractNioByteChannel$NioByteUnsafe.read(AbstractNioByteChannel.java:135) at com.couchbase.client.deps.io.netty.channel.nio.NioEventLoop.processSelectedKey(NioEventLoop.java:646) at com.couchbase.client.deps.io.netty.channel.nio.NioEventLoop.processSelectedKeysOptimized(NioEventLoop.java:581) at com.couchbase.client.deps.io.netty.channel.nio.NioEventLoop.processSelectedKeys(NioEventLoop.java:498) at com.couchbase.client.deps.io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:460) at com.couchbase.client.deps.io.netty.util.concurrent.SingleThreadEventExecutor$2.run(SingleThreadEventExecutor.java:131) at com.couchbase.client.deps.io.netty.util.concurrent.FastThreadLocalRunnable.run(FastThreadLocalRunnable.java:30) at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.IndexOutOfBoundsException: readerIndex(0) + length(1) exceeds writerIndex(0): PooledUnsafeDirectByteBuf(ridx: 0, widx: 0, cap: 256) at com.couchbase.client.deps.io.netty.buffer.AbstractByteBuf.checkReadableBytes0(AbstractByteBuf.java:1161) at com.couchbase.client.deps.io.netty.buffer.AbstractByteBuf.readByte(AbstractByteBuf.java:591) at com.couchbase.client.core.utils.yasjl.ByteBufJsonParser.readNextChar(ByteBufJsonParser.java:458) at com.couchbase.client.core.utils.yasjl.ByteBufJsonParser.parse(ByteBufJsonParser.java:109) at com.couchbase.client.core.endpoint.query.parser.YasjlQueryResponseParser.parse(YasjlQueryResponseParser.java:337) at com.couchbase.client.core.endpoint.query.QueryHandlerV2.decodeResponse(QueryHandlerV2.java:175) at com.couchbase.client.core.endpoint.query.QueryHandlerV2.decodeResponse(QueryHandlerV2.java:62) at com.couchbase.client.core.endpoint.AbstractGenericHandler.decode(AbstractGenericHandler.java:338) ... 29 more

I have tested the N1QL on a real Couchbase server and it worked well. Could any one help me out? Thanks
