This document is a declaration of software quality for the rmw_fastrtps_dynamic_cpp
package, based on the guidelines in REP-2004.
The package rmw_fastrtps_dynamic_cpp
claims to be in the Quality Level 3 category.
Below are the rationales, notes, and caveats for this claim, organized by each requirement listed in the Package Requirements for Quality Level 3 in REP-2004.
rmw_fastrtps_dynamic_cpp
uses semver
according to the recommendation for ROS Core packages in the ROS 2 Developer Guide.
rmw_fastrtps_dynamic_cpp
is at a stable version, i.e. >= 1.0.0
.
The current version can be found in its package.xml, and its change history can be found in its CHANGELOG.
All symbols in the installed headers are considered part of the public API.
All installed headers are in the include
directory of the package, headers in any other folders are not installed and considered private.
rmw_fastrtps_dynamic_cpp
will not break public API within a released ROS distribution, i.e. no major releases once the ROS distribution is released.
rmw_fastrtps_dynamic_cpp
contains C and C++ code and therefore must be concerned with ABI stability, and will maintain ABI stability within a ROS distribution.
rmw_fastrtps_dynamic_cpp
follows the recommended guidelines for ROS Core packages in the ROS 2 Developer Guide.
This package requires that all changes occur through a pull request.
This package uses DCO as its confirmation of contributor origin policy. More information can be found in CONTRIBUTING.
Following the recommended guidelines for ROS Core packages, all pull requests must have at least 1 peer review. Check ROS 2 Developer Guide for additional information.
All pull request must pass CI on all tier 1 platforms.
All pull requests must resolve related documentation changes before merging.
Some of the rmw_fastrtps_dynamic_cpp
features are documented on the repository level README.
Much of Fast DDS itself has feature documentation hosted publicly.
Most of rmw_fastrtps_dynamic_cpp
has embedded API documentation. It is not yet hosted publicly.
The license for rmw_fastrtps_dynamic_cpp
is Apache 2.0, and a summary is in each source file, the type is declared in the package.xml manifest file, and a full copy of the license is in the LICENSE file.
There is an automated test which runs a linter that ensures each file has a license statement.

All rmw_fastrtps_dynamic_cpp
public features are ROS middleware features.
Unit, integration, and system tests higher up in the stack, such as those found in test_rmw_implementation
, test_rclcpp
, and test_communication
packages, provide feature coverage. Nightly extra_rmw_release
CI jobs also test this middleware implementation.
rmw_fastrtps_dynamic_cpp
implements the ROS middleware public API, but also provides public API of its own.
Unit tests located in the test
directory provide coverage for public but rmw_fastrtps_dynamic_cpp
specific API.
New additions or changes to this API require tests before being added.
Unit, integration, and system tests higher up in the stack, such as those found in test_rmw_implementation
, test_rclcpp
, and test_communication
packages, ensure compliance with the ROS middleware API specification (see rmw
package) and further extend coverage.
Currently, rmw_fastrtps_dynamic_cpp
is not included in the nightly CI coverage report.
Coverage checks should be made to consider this package to apply for a higher quality level.
rmw_fastrtps_dynamic_cpp
does not currently have performance tests.
rmw_fastrtps_dynamic_cpp
uses and passes all the standard linters and static analysis tools for a C++ package as described in the ROS 2 Developer Guide.
Results of the nightly linter tests can be found here.
rmw_fastrtps_dynamic_cpp
has the following runtime ROS dependencies:

The Quality Declarations for the last two dependencies are not available currently.
It has several "buildtool" dependencies, which do not affect the resulting quality of the package, because they do not contribute to the public library API. It also has several test dependencies, which do not affect the resulting quality of the package, because they are only used to build and run the test code.
rmw_fastrtps_cpp
has the following runtime non-ROS dependencies.
