YARP 3.5.0 Release Notes

A (partial) list of bug fixed and issues resolved in this release can be found
here.

Important Changes

Dependencies

YCM 0.13 is now required.
OpenCV 2 is no longer supported.
Added optional Zlib dependency.
Qt 5.4 or later is now requred to build YARP GUIs.

Libraries

`sig`

`Image`

Bottom to top images are no longer flipped when sent through the network. This
means that the image needs to be manually flipped after it is received.
Bottom to top images might cause issues when received by YARP 3.4.5 or
earlier.

Devices

The ovrheadset device driver was moved to
https://github.com/robotology/yarp-device-ovrheadset
The realsense2, realsense2withIMU and realsense2Tracking device drivers
were moved to https://github.com/robotology/yarp-device-realsense2
This release introduces the Network Wrapper Server/Client Architecture
as described in Network Wrapper Server/Client Architecture #2441. This architecture enables ROS2 compatibility
which is currently developed in the
yarp-ros2 repository.

Deprecation and Behaviour Changes

A few default values for the environment variables used by yarp are now
different:
- Linux:
  - YARP_CONFIG_DIRS defaults to /etc/xdg/yarp to be compliant with the
    XDG Base Directory Specification
- Windows:
  - YARP_DATA_DIRS defaults to %%ALLUSERSPROFILE%%\yarp
  - YARP_CONFIG_DIRS defaults to %%ALLUSERSPROFILE%%\yarp\config

This is an API break, but nobody should be using these outside of YARP.
The flag VOCAB_NAV_CLEAR_X, defined in file ILocalization2D.h has been
renamed to VOCAB_NAV_CLEARALL_X to avoid confusion with flag
VOCAB_NAV_DELETE_X.
VOCAB_NAV_CLEARALL_X clears all data belonging to the same category (all
maps, all locations, all areas, etc), while VOCAB_NAV_DELETE_X, deletes a
single entity (a map with name x, a location with name x etc).

`os`

Introduced the yarp::os::Header class, intended to gradually replace the
yarp::os::Stamp class to handle envelopes, maintaining backwards
compatibility.
The differences with the Stamp class:
- Header has an extra field to handle the frame id, making it comparable
  with ROS std_msgs/Header
  message.
- The counter uses unsigned int instead of int.
- Stamp::getMaxCount() is replaced with Header::npos
- Stamp::getCount() is replaced with Header::count()
- Stamp::getTime() is replaced with Header::timeStamp()

`Bottle`

Added BOTTLE_TAG_VOCAB32 tag. This is the same as BOTTLE_TAG_VOCAB.
The usage of BOTTLE_TAG_VOCAB is not recommended in new code, use
BOTTLE_TAG_VOCAB32 instead.
Added addVocab32() overloads accepting 4 chars and string.

`DummyConnector`

The getReader methods now accepts a ConnectionWriter as optional
parameter. This writer is returned by getWriter is called on the
ConnectionReader returned by the writer, and it is therefore used for the
replies in Portables and in a few other cases.

`Log`

The YARP_FORWARD_CODEINFO_ENABLE, YARP_FORWARD_HOSTNAME_ENABLE,
YARP_FORWARD_PROCESSINFO_ENABLE, and YARP_FORWARD_BACKTRACE_ENABLE are no
longer considered experimental.

`PeriodicThread`

The constructor now accepts a third (optional) parameter, clockAccuracy,
which enables drift compensation using an absolute time reference to ensure
all steps trigger at precise intervals, thus avoiding error accumulation over
time. Set it to PeriodicThreadClock::Absolute to enable the new behavior,
default is PeriodicThreadClock::Relative (old behavior). Beware that, in
absolute mode, starvation may occur if two busy threads share a common
resource (PeriodicThread accumulates error over time #2488).
Added new constructor:
- PeriodicThread(double period, PeriodicThreadClock clockAccuracy).

`Property`

.ini configuration files can now contain the command
[import <contextname> <filename>] which includes a .ini file from a
different context.

`Value`

Added makeVocab32() overload accepting 4 chars

`Wire`

Added yarp() const overload

`WireLink`

The write method is now const. The signature is now:

bool write(const PortWriter& writer, PortReader& reader) const

`WireReader`

- void normalizeChannel(size_t channel)
- void normalize()

`utils`

Added cropRect() helper function for cropping a rectangle area out of an
image given two opposite vertices.

`dev`

Added the new WrapperSingle and WrapperMultiple helper classes, that
inherit from both IWrapper and IMultipleWrapper but require to implement
only one of these interfaces.
Added the template class IFrameGrabberOf<typename ImageType>.
It is now possible to implement the same interface as for IFrameGrabberImage
and IFrameGrabberImageRaw, but for different pixel types or for FlexImage.
Added the new datatypes generated by thrift:
- yarp::dev::AudioRecorderStatus
- yarp::dev::AudioPlayerStatus
Added the new class AudioPlayerDeviceBase, all playback device drivers now
inherit from this class.
Added the new class AudioRecorerDeviceBase, all recording device drivers now
inherit from this class.

`IFrameGrabberImage`

The getImageCrop method has now a working default implementation.
The IFrameGrabberImage interface is now an alias for
IFrameGrabberOf<yarp::sig::ImageOf<yarp::sig::PixelRgb>>.

`IFrameGrabberImageRaw`

The getImageCrop method has now a working default implementation.
The IFrameGrabberImageRaw interface is now an alias for
IFrameGrabberOf<yarp::sig::ImageOf<yarp::sig::PixelMono>>.

`IAudioRender`

Added the new methods:
- bool setHWGain(double gain)
- bool setSWGain(double gain)

`IAudioGrabberSound`

Added the new methods:
- bool setHWGain(double gain)
- bool setSWGain(double gain)

`Lidar2DDeviceBase`

The Lidar2DDeviceBase class, now implements yarp::dev::IPreciselyTimed.
All lidar devices must implement the method acquireDataFromHW() which is
pure virtual in Lidar2DDeviceBase
Lidar devices can optionally call the method
Lidar2DDeviceBase::updateLidarData, which calls acquireDataFromHW() and a
few other utility functions (e.g. updateTimestamp(), etc.)
The run() method of the devices, which was previously responsible for the data
collection, now just calls updateLidarData().

`Nav2D::IMap2D`

Added the new methods:
- bool clearAllMapsTemporaryFlags()
- bool clearMapTemporaryFlags(std::string map_name)
- bool saveLocationsAndExtras(std::string locations_collection_file)
- bool loadLocationsAndExtras(std::string locations_collection_file)

`Nav2D::MapGrid2D`

Added the new method:
- void clearMapTemporaryFlags()
Added internal lossless compression using Zlib.
The write() and read() methods handle the compression before sending data
to the network.
Added method enable_map_compression_over_network() to enables/disables data
compression over the network (default true). Compression is always disabled if
Zlib library is not available.
Improved logic to convert ros map images to ros occupancy data and viceversa.

`Nav2D::Map2DLocation`

Added the new method
- bool is_near_to(const Map2DLocation& other_loc, double linear_tolerance, double angular_tolerance) const

`robotinterface`

The robotinterface library is no longer considered experimental, files and
classes have been moved accordingly.
robotinterface DTD version is now 3.1.

It is now possible to pass the device parameter to the attach action,
without defining network or networks. For example:

<device name="foo_name" type="foo_type">
  <action phase="startup" level="5" type="attach">
    <param name="device"> bar_name </param>
  </action>
  <action phase="shutdown" level="5" type="detach" />
</device>

`XMLReader`

The getRobotFromFile and getRobotFromString now accept a Searchable that
is used to replace params with the attribute extern-name.
The signatures are now:

    XMLReaderResult getRobotFromFile(const std::string& filename,
                                     const yarp::os::Searchable& config = yarp::os::Property());
    XMLReaderResult getRobotFromString(const std::string& filename,
                                       const yarp::os::Searchable& config = yarp::os::Property());

Carriers

The unix_stream carrier is no longer considered experimental.

Port Monitors

There is now a new yarppm library (similar to yarpcar and yarpmod) that
links all the portmonitors in static builds.
Added image_compression_ffmpeg port monitor to compress a video stream using
the H264, H265, or MPEG2VIDEO codec.
Added sound_compression_mp3 port monitor to decompress a mp3 bytestream to
yarp::sig::Sound. Encoding not supported yet.
Added depthimage_compression_zlib port monitor which uses the Zlib library
to compress/decompress (lossless) depth images through the network.

Devices

`AudioPlayerWrapper`

Added RPC commands to control the volume via setHWGain() and setSWGain().
It now broadcasts its internal status on a xxx/status:o port

`AudioRecorderWrapper`

Added RPC commands to control the volume via setHWGain() and setSWGain().
It now broadcasts its internal status on a xxx/status:o port

`fakeFrameGrabber`

added RPC port, to change its mode at runtime. It is also possibile to load a
new background image at runtime.
Rpc command 'help' will display available commands.
Added --timestamp option to write the timestamp in the first bytes of the
image. This was previously automatically enabled in line mode, but it can
now be used in all modes.
Double buffering is now used to produce the image on a separate thread. This
should improve performances when generating large images.
The getImage() method no longer blocks the caller.
The --syncro option was added to restore the old behavior.
The topIsLow option and the set_topIsLow rpc command were added to produce
images with bottom to top scanlines.
Added --noise options and set_noise RPC commands to add a a white noise to
the generated image.
Added --snr option and set_snr RPC commands. to specify the signal noise
ratio if noise is enabled.

`fakeLaser`

Added rpc port to dynamically create obstacles in the map. Use the rpc command
'help' to get additional information.
Improved the ray tracing algorithm: laser scans are now bound to the map size.
Added map_context parameter to load a test map from a specific context.

`fakeMicrophone`

It now generates a fixed tone sound.

`fakeNavigation`

Several improvements for testing purposes.

`frameTransformServer`

Added a new RPC command generate_view which generates via dot (graphviz)
a pdf file, containing a diagram of the transforms tree.

`map2DServer`

Added enable_maps_compression <0/1> RPC command.

`navigation2DClient`

getNameOfCurrentTarget() logic moved from Navigation2DClient to
navigation2DServer.

Tools

Added yarpdataplayer-console tool that works without without a graphic
server.

`yarp`

The read subcommand now accepts the trim argument to reduce the number of
characters printed for each message received.
Added the following new subcommands:
- yarp latency-test: performs a latency test exchanging data between a
  server and a client node.
- yarp repeat: repeats in an output port all data received in an input port.
  The command is useful to control stream flows on a wifi/mobile connection.
- yarp stats: opens a temporary port to receive data from a remote port (at
  maximum speed). It also prints basic statistics about data trasferred on the
  instantiated connection.
- yarp trafficgen: sends generated data over a yarp port. The tool allows to
  test the communication and the available bandwidth over the network.

`yarpdatadumper`

The following data outputs for the --type parameter are now supported:
- bottle (default)
- image
- image_jpg
- image_png
- video
- depth
- depth_compressed

`yarprobotinterface`

Arguments taken from the command line are now handled and used to replace
parameters marked with the attribute extern-name.

`yarpidl_thrift`

Thrift was updated to version 0.14.1.

Added support for uint8_t, uint16_t, uint32_t, uint64_t, size_t,
float32_t and float64_t using annotated types.
It is now possible to use these types in thrift by defining them using a
typedef, for example:

typedef i32 ( yarp.type = "yarp::conf::vocab32_t" ) vocab
typedef i8 ( yarp.type = "std::uint8_t" ) ui8
typedef i16 ( yarp.type = "std::uint16_t" ) ui16
typedef i32 ( yarp.type = "std::uint32_t" ) ui32
typedef i64 ( yarp.type = "std::uint64_t" ) ui64
typedef i32 ( yarp.type = "size_t" ) size_t
typedef double ( yarp.type = "yarp::conf::float32_t" ) float32
typedef double ( yarp.type = "yarp::conf::float32_t" ) float64

struct TestAnnotatedTypes
{
  1: vocab a_vocab,
  2: ui8 a_ui8,
  3: ui16 a_ui16,
  4: ui32 a_ui32,
  5: ui64 a_ui64,
  6: float32 a_float32,
  7: float64 a_float64,
  8: size_t a_size;
}

Types annotated with "yarp.type" are no longer serialized as nested.
This improves the compatibility with existing services returning Bottle
or other YARP types, and makes it possible to write a thrift file for
existing protocols.
On the other hand, this breaks compatibility with thrift services
returning Bottles or other annotated types, generated before this
commit. This is a breaking change, but should impact only a very
limited number of cases, and it can be easily fixed by regenerating the
files.
Added support for vocabs in structs (thrift: Vocabs are not supported in structs #2476).
Vocabs can be defined in this way:
```
typedef i32 ( yarp.type = "yarp::conf::vocab32_t" ) vocab

struct FooStruct
{
    1: vocab foo;
}
```
Added "yarp.nested" annotation for struct fields
When defined = "true", this serialize a struct as a bottle instead of as a
flat structure.
For example, given these 2 structs:
```
struct Foo
{
    1: double foo1;
    2: double foo2;
}

struct Bar
{
    1: double bar1;
    2: Foo ( yarp.nested = "true" );
}
```
The Bar struct will be serialized as bar1 (foo1 foo2), instead of as a
flat struct bar1 foo1 foo2.
It is now possible to specify a "const" qualifier to service methods using the
yarp.qualifier annotation. For example, this code:
```
service Foo {
  bool const_method() (yarp.qualifier = "const");
}
```
will generate a service Foo with this method:
```
bool const_method() const
```

GUIs

`yarpview`

Added the --rightout <portname> option that enables intercepting the mouse
right button click events:
- Single click (sends the current cursor coordinates to the specified output
  port)
- Press, drag, and release (sends the coordinates of the press point and of
  the release one to the specified output port)
Added Image/Intercept right click checkable menu item to enable/disable
the right click interception (not available in minimal or compact mode or
if the --rightout option was not enabled).

yarpdataplayer

It is now possible to reproduce depth and depth_compressed data types.
The yarpdataplayer tool was refactored, several bugs fixed, and new features
added (yarpdataplayer enhancements #1144, [yarpdataplayer] Provide status flag to check if player has finished playing a loaded dataset #2140, [yarpdataplayer] step command in rpc exhibits odd behaviors #2151, yarpdataplayer --hidden cannot start on headless system #2400, yarpdataplayer closes immediately after loading data with --hidden flag is used #2401, Refactoring of the yarpdataplayer module #2442).

Bindings

Added support for std::vector<short int>.
Added support for yarp::sig::VectorOf<int>.
Added the following extensions to yarp::sig::Sound
- sound2VecNonInterleaved()
- vecNonInterleaved2Sound()
- sound2VecInterleaved()
- vecInterleaved2Sound()

New Experimental Features

EXPERIMENTAL means that the software is under development, provided with
incomplete documentation and it may be modified/renamed/removed without any
notice.

Carriers

Added new EXPERIMENTAL websocket carrier.
It works only on the receiving side, and it works on an http request
that starts with "GET /?ws" (for example 'http://127.0.0.1:10002/?ws'
or 'ws://127.0.0.1:10002/?ws' if a read port is opened by yarp).
The websocket, on the browser side, needs to communicate using the YARP
protocol.

Devices

Added the following new EXPERIMENTAL devices:
- RGBDFromRosTopic: it can be wrapped by RGBDSSensorWrapper to make RGBD
  data, collected by a ROS device, available on YARP via RGBDSensorClient.
- map2DStorage: store navigation data, e.g MapGrid2D,Map2DLocation etc.
  It implements all the logic previously located inside device 'Map2DServer'.
- audioFromFileDevice: wrapped by audioRecorderWrapper.
- audioToFileDevice: wrapped by audioPlayerWrapper.
- frameGrabberCropper: attaches to a frameGrabber and published part of the
  image
- frameTransformStorage
- frameTransformSetMultiplexer
- frameTransformGetMultiplexer
Several new EXPERIMENTAL devices were added in order to implement the
Network Wrapper Server/Client Architecture described in Network Wrapper Server/Client Architecture #2441.
These devices do not implement internal logic, therefore they might need to be
used together with a different device.
This architecture and all these devices are to be considered experimental,
and may be modified/renamed/removed at any time without any notice.
- controlBoard_nws_ros: ROS NWS that can be used to replace
  controlboardwrapper2 (does not handle networks, use controlboardremapper
  for that). It requires that the yarp::dev::IAxisInfo is implemented in the
  device.
- controlBoard_nws_yarp: YARP NWS that can be used to replace
  controlboardwrapper2 (does not handle networks, use controlboardremapper
  for that).
- frameGrabber_nws_ros: ROS NWS that can be used to replace
  grabberDual (does not handle image split, use frameGrabberCropper for
  that)
- frameGrabber_nws_yarp: YARP NWS that can be used to replace
  grabberDual (does not handle image split, use frameGrabberCropper for
  that)
- frameGrabber_nwc_yarp: YARP NWC that can be used to replace
  remote_grabber
- localization2D_nws_ros: ROS NWS for devices which implement the
  ILocalization2D interface, that can be used to replace
  localization2DServer.
- localization2D_nws_yarp: YARP NWS for devices which implement the
  ILocalization2D interface, that can be used to replace
  localization2DServer.
- map2D_nws_ros: ROS NWS for a map2DStorage device.
- map2D_nws_yarp: YARP NWS for a map2DStorage device.
- rangefinder2D_nws_ros: ROS NWS for devices exposing
  IRangefinder2D interface.
- rangefinder2D_nws_yarp: YARP NWS for devices exposing
  IRangefinder2D interface.
- rgbdSensor_nws_ros: ROS NWS to replace RGBDSensorWrapper.
- rgbdSensor_nws_yarp: YARP NWS to replace RGBDSensorWrapper.
- rgbdToPointCloudSensor_nws_ros: enables point cloud publication from yarp
  to ros. It converts RGBD data to point cloud and publishes it on a ros
  topic.
- frameTransformGet_nws_ros
- frameTransformGet_nws_yarp
- frameTransformSet_nws_ros
- frameTransformSet_nws_yarp
  All these interfaces have the following differences with their original
  wrappers:
- All deprecated parameters were removed
- Periods are in seconds, and not in milliseconds.
- Parameters in nws_ros devices no longer have the "ROS_" prefix".
Added new EXPERIMENTAL devices frameTransformClient and frameTransformServer.
These devices are mostly empty containers for multiple plugins that can be
combined together through a yarprobotinterface xml file.
Different configuration files can be used for different purposes, such as
publishing/subscribing transforms on YARP, ROS, ROS2 etc. Please refer to the
documentation for additional details.
Old devices with frame transform management functionality are called
transformServer and transformClient. These devices should be now
considered deprecated and they must be not confused with the new devices
included in this PR. A yarp page documentation has been added to show the
different possible configurations.
The laserFromRosTopic is still considered EXPERIMENTAL, since it will
be replaced by an appropriate NWC

Bindings

Python

Introduced unofficial support to install YARP with tools like pip.
A new yarp-middleware package is now distributed in PyPI.

Bug Fixes

Libraries

`sig`

`Image`

The topIsLow flag is now properly handled, kept in sync with the internal
IplImage, and forwarded through the network.

`ImageFile`

Fixed SavePNG() producing corrupted output files.

Carriers

`portmonitor`

The reply handler is now set correctly, it is therefore now possible to
monitor RPC connections.

Devices

`grabberDual`

The topIsLow flag is no longer changed.

Devices

`RGBDSensorClient`

The device no longer crashes when no image was received yet (Side effects of copying an empty/invalid yarp::sig::Image #2349).
The timestamp is now correct.

`map2DServer`

Fixed issue preventing correct file save/load operations of locations data.

GUIs

yarpdataplayer

Timestamp is now interpreted correctly, dealing with locale issues (yarpdataplayer timestamp gets rounded because of Ubuntu regional format #2558).
Fixed step command in RPC exhibiting odd behaviors ([yarpdataplayer] step command in rpc exhibits odd behaviors #2151).
