# `rmw_fastrtps_dynamic_cpp` Quality Declaration

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](https://www.ros.org/reps/rep-2004.html).

## Version Policy [1]

### Version Scheme [1.i]

`rmw_fastrtps_dynamic_cpp` uses `semver` according to the recommendation for ROS Core packages in the [ROS 2 Developer Guide](https://index.ros.org/doc/ros2/Contributing/Developer-Guide/#versioning).

### Version Stability [1.ii]

`rmw_fastrtps_dynamic_cpp` is at a stable version, i.e. `>= 1.0.0`.

### Public API Declaration [1.iii]

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.

### API Stability Within a Released ROS Distribution [1.iv]/[1.vi]

`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.

All pull requests must resolve related documentation changes before merging.

## Documentation [3]

### Feature Documentation [3.i]

Some of the `rmw_fastrtps_dynamic_cpp` features are documented on the repository level [README](../README.md).
Much of Fast DDS itself has feature documentation [hosted publicly](https://fast-dds.docs.eprosima.com/en/latest/).

Most of `rmw_fastrtps_dynamic_cpp` has embedded API documentation. It is not yet hosted publicly.

### License [3.iii]

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](package.xml) manifest file, and a full copy of the license is in the [LICENSE](../LICENSE) file.

There is an automated test which runs a linter that ensures each file has a license statement.

Most recent test results can be found [here](https://ci.ros2.org/view/nightly/job/nightly_linux_extra_rmw_release/lastCompletedBuild/testReport/rmw_fastrtps_dynamic_cpp/copyright/)

### Copyright Statements [3.iv]

The copyright holders each provide a statement of copyright in each source code file in `rmw_fastrtps_dynamic_cpp`.

There is an automated test which runs a linter that ensures each file has at least one copyright statement.

The results of the test can be found [here](https://ci.ros2.org/view/nightly/job/nightly_linux_extra_rmw_release/lastCompletedBuild/testReport/rmw_fastrtps_dynamic_cpp/copyright/).

## Testing [4]

### Feature Testing [4.i]

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`](https://github.com/ros2/rmw_implementation/tree/master/test_rmw_implementation), [`test_rclcpp`](https://github.com/ros2/system_tests/tree/master/test_rclcpp), and [`test_communication`](https://github.com/ros2/system_tests/tree/master/test_communication) packages, provide feature coverage. [Nightly `extra_rmw_release` CI jobs](https://ci.ros2.org/view/nightly/) also test this middleware implementation.

### Public API Testing [4.ii]

`rmw_fastrtps_dynamic_cpp` implements the ROS middleware public API, but also provides public API of its own.

Unit tests located in the [`test`](https://github.com/eProsima/rmw_fastrtps/tree/master/rmw_fastrtps_dynamic_cpp/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`](https://github.com/ros2/rmw_implementation/tree/master/test_rmw_implementation), [`test_rclcpp`](https://github.com/ros2/system_tests/tree/master/test_rclcpp), and [`test_communication`](https://github.com/ros2/system_tests/tree/master/test_communication) packages, ensure compliance with the ROS middleware API specification (see [`rmw`](https://github.com/ros2/rmw) package) and further extend coverage.

### Coverage [4.iii]

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.

### Performance [4.iv]

`rmw_fastrtps_dynamic_cpp` does not currently have performance tests.

### Linters and Static Analysis [4.v]

`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](https://index.ros.org/doc/ros2/Contributing/Developer-Guide/#linters).

Results of the nightly linter tests can be found [here](https://ci.ros2.org/view/nightly/job/nightly_linux_extra_rmw_release/lastCompletedBuild/testReport/rmw_fastrtps_dynamic_cpp/).

## Dependencies [5]

### Direct Runtime ROS Dependencies [5.i]/[5.ii]

`rmw_fastrtps_dynamic_cpp` has the following runtime ROS dependencies:
* `fastrtps_cmake_module`
* `rcpputils`
* `rcutils`
* `rmw`
* `rmw_dds_common`
* `rmw_fastrtps_shared_cpp`
* `rosidl_runtime_c`
* `rosidl_typesupport_fastrtps_c`
* `rosidl_typesupport_fastrtps_cpp`
* `rosidl_typesupport_introspection_c`
* `rosidl_typesupport_introspection_cpp`

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.

### Direct Runtime Non-ROS Dependencies [5.iii]

`rmw_fastrtps_cpp` has the following runtime non-ROS dependencies.
* `fastcdr`: [QUALITY DECLARATION](https://github.com/eProsima/Fast-CDR/blob/master/QUALITY.md)
* `fastrtps`: [QUALITY DECLARATION](https://github.com/eProsima/Fast-DDS/blob/master/QUALITY.md)
