You can find the following output, the request type is STREAM_DATA, but the
reply type is STREAM_HEADER. I will test the previous version I have test again.
{code:java}
succ:true reply written:0 expected:1000000
clientId:client-6C3D34F237DA,type:STREAM_HEADER,streamId4,offset:0,datalength:0
localWrite:1927248929 remoteWrites:789787006
request:DataStreamRequestByteBuf:clientId=client-F1F2794DEFF0,type=STREAM_DATA,id=4,offset=48000000,length=1000000
{code}
{code:java}
composeAsync(info.getPrevious(), requestExecutor, n ->
JavaUtils.allOf(remoteWrites)
.thenCombineAsync(localWrite, (v, bytesWritten) -> {
if (request.getType() == Type.STREAM_HEADER
|| (request.getType() == Type.STREAM_DATA && !close)) {
for (CompletableFuture<DataStreamReply> replyFuture : remoteWrites)
{
final DataStreamReply reply = replyFuture.join();
if (!reply.isSuccess() || reply.getBytesWritten() !=
bytesWritten) {
+ System.err.println("succ:" + reply.isSuccess() + " reply
written:" + reply.getBytesWritten() +
" expected:" + bytesWritten + " clientId:" +
reply.getClientId() + ",type:" + reply.getType() + ",streamId" +
reply.getStreamId() + ",offset:" + reply.getStreamOffset()
+ ",datalength:" + reply.getDataLength() +
" localWrite:" + localWrite.hashCode() + " remoteWrites:" +
remoteWrites.hashCode() + " request:" + request);
}
}
sendReply(remoteWrites, request, bytesWritten, ctx, close);
}
{code}
