Regular Business

Buildfarm update

The buildfarm builds and tests ROS packages across all supported distributions and platforms. This section covers new issues, current priorities, and infrastructure changes that affect maintainers.

• Issues:
  • rmw_cyclonedds_cpp build emits a -fvisibility-inlines-hidden warning when compiling C code. Missing backport.
  • Windows build warns about exceeding the CMake object file path length in rosbag2_performance_benchmarking_msgs.
  • Build warning: __builtin_memmove out of bounds in test_buffer.cpp under GCC 15.
  • Intermittent Windows failures in the type description service and parameter events tests with Connext DDS.
• Priorities:
  • PTAL Buildfarm Issues Dashboard (22 open issues).

Waffle note-taker

Waffle is a weekly meeting where maintainers triage incoming issues and pull requests that haven’t been otherwise acted upon. One person per week is assigned to be the “waffle note-taker” to both take notes in the meeting to keep the meeting as efficient as possible.
