v3.4.3 regression: yarprobotinterface floods its output with Command received and Response sent: messages

[traversaro]

Describe the bug
After https://github.com/robotology/yarp/pull/2485/files, yarprobotinterface on the yarp-3.4 branch and on releases v3.4.3, v3.4.4 and v3.4.5 is flooding its output with Command received and Response sent:, making really hard to read the other relevant output. The problem was fixed in master (YARP 3.5) in d02db05#diff-3bbd8f68798112a6c309136664e4e9bb42af65bec13be7143219a14551c38aa8 , but the nature of the bug is such that it is complicated to use yarprobotinterface with v3.4.3/v3.4.4/v3.4.5 releases.

To Reproduce
Run yarprobotinterface (probably @xEnVrE @S-Dafarra can add more input).

Expected behavior
The log should contains relevant output, not the same message repeatdly printed.

Screenshots

Configuration (please complete the following information):

• OS: Ubuntu 20.04
• yarp version: v3.4.3
• compiler: GCC 9

Additional context
This problem was detected by both @S-Dafarra and @xEnVrE .

A fix for this issue is provided in #2631 .

@S-Dafarra @xEnVrE as a temporary workaround, you can ensure that YARP does not print Debug statements by defining the environment variable YARP_DEBUG_ENABLE to 0 , see http://www.yarp.it/git-master/yarp_logging.html#autotoc_md911 for more info.

[S-Dafarra]

Thanks a lot @traversaro for opening the issue. While rushing for a deadline, we simply commented out the lines affected by d02db05

[S-Dafarra]

Run yarprobotinterface (probably @xEnVrE @S-Dafarra can add more input).

That was happening when opening a yarpmotorgui for example, saturating the logger in seconds.
