TCPConnection: Handle Joined Messsages

Open aaronsnoswell opened this issue 8 years ago • 6 comments

Hi Sanic,

I'm trying to implement support for sensor_msgs/PointCloud2 (and friends) so I can visualize point clouds in UE4. See my branch support-point-clouds.

So far, I have successfully added the message definitions for the required message types. I have a Ubuntu 16.04 ROS kinetic instance running ROSBridge in BSON mode, and I'm publishing a topic that is a throttled sensor_msgs/PointCloud2 (about 1 frame every 2 seconds). I can visualize the PointCloud2 in RVIZ just fine, and I know my ROS <> UE4 connection is fine, because I can subscribe / publish std_msgs/String topics without error.

When I try to subscribe to the sensor_msgs/PointCloud2 topic, the BSON parsing fails at bson_init_static() circa line 254 in TCPConnection.cpp. I believe this is happening because of a comment circa line 140 in TCPConnection - it says

// TODO handle joined messages while reading the buffer
uint32 count;

After changing the std::cout calls in TCPConnection.cpp to UE_LOG calls, I get the following console output in Unreal;

Do you think this error could be because 'handle joined messages while reading the buffer' hasn't been implemented yet? What would it take to implement this? If it would make it easier for you to assist me, I can share a bagfile that publishes a simple sensor_msgs/PointCloud2 topic for testing purposes.

Thank you,

Aaron.

It might be easier to get the gist of the UE4 log in an image;

ue4_bson_parse_fail

aaronsnoswell avatar Jan 23 '18 01:01 aaronsnoswell

Another update here: I updated my ROS nodes so that I'm downsampling the point cloud massively (see https://github.com/aaronsnoswell/ue4_comms_test/blob/master/src/pcl_downsampler.cpp). When I do this, I am able to recieve the sensor_msgs/PointCloud2 messages fine. As such, this definitely seems to be a problem with receiving large bson messages that are split over multiple TCP packets.

Can we work out an approach to fixing this problem? I'm happy to do the work if you advise what needs to be done :) I'm not super familiar with the code in TCPConnection.cpp

aaronsnoswell avatar Jan 23 '18 07:01 aaronsnoswell

Hi @aaronsnoswell Thanks for opening this issue and sorry for the delay. This problem might be indeed a problem with the TCPConnection class. I think the relevant part starts at https://github.com/code-iai/ROSIntegration/blob/7e1716c4098693aef746165f17531e9cd0265ed7/Source/ROSIntegration/Private/rosbridge2cpp/TCPConnection.cpp#L205 . The main idea is to begin by reading the first 4 bytes. These bytes represent the length field of a bson packet: http://bsonspec.org/spec.html. By reading this length, we can instruct the next recv() calls to receive exactly that many bytes. After these 4 four bytes have been read, bson_state_read_length will be false. This will cause the jump to https://github.com/code-iai/ROSIntegration/blob/7e1716c4098693aef746165f17531e9cd0265ed7/Source/ROSIntegration/Private/rosbridge2cpp/TCPConnection.cpp#L237 to handle the actual message reception. I guess the problems begin there. Maybe if( _sock->Recv(binary_temp.GetData(), bson_msg_length - 4, bytes_read) ) can return less then the requested bson_msg_length - 4 bytes on fragmented packets. So one would have to reiterate to collect more data in the buffer. Additionally, i'm not 100% sure if if(msg_size_in_buffer == bson_msg_length) is correct. msg_size_in_buffer is calculated by calling Num() on a TArray. However, this array is resized with SetNumUninitialized() : https://github.com/code-iai/ROSIntegration/blob/7e1716c4098693aef746165f17531e9cd0265ed7/Source/ROSIntegration/Private/rosbridge2cpp/TCPConnection.cpp#L245 So Num() may not count the actual elements in the list, but rather the received elements + uninitialized elements.

As a reference on how it could be done, you can check the implementation on the rosbridge_server side: https://github.com/RobotWebTools/rosbridge_suite/blob/develop/rosbridge_server/src/rosbridge_server/tcp_handler.py#L62

Hemofektik avatar Mar 20 '18 14:03 Hemofektik

Has this been fixed now? I am just reviewing the code for TCPConnection.cpp and it looks substantially different to what it did in 2018, and appears that it will correctly wait to fill a buffer based on the 4 byte BSON prefix.

However we are still receiving BSON decode issues with our pointcloud frames ("Error on BSON parse - Ignoring message"), using v0.11.10 of rosbridge server. Any clue if this could be related to it?

@Sanic

. The main idea is to begin by reading the first 4 bytes. These bytes represent the length field of a bson packet: http://bsonspec.org/spec.html.

So one would have to reiterate to collect more data in the buffer.

About a year ago I had this exact problem you're describing Sanic, so I modified TCPConnection.cpp to be able to read headers from fragmented packets. I have a pending pull request #179 on this . Would appreciate if someone could have a look at it and accept it if it seems OK. I've been using my modified version multiple times now over the last year without any apparent problem.
