QUALITY_DECLARATION

This document is a declaration of software quality for the trajectory_msgs package, based on the guidelines in REP-2004.

trajectory_msgs Quality Declaration

The package trajectory_msgs claims to be in the Quality Level 1 category as long as it is used with a Quality Level 1 middleware.

Below are the rationales, notes, and caveats for this claim, organized by each requirement listed in the Package Requirements for Quality Level 1 in REP-2004.

Version Policy [1]

Version Scheme [1.i]

trajectory_msgs uses semver according to the recommendation for ROS Core packages in the ROS 2 Developer Guide.

Version Stability [1.ii]

trajectory_msgs 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.

Public API Declaration [1.iii]

All message and service definition files located in msg and srv directories are considered part of the public API.

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

trajectory_msgs will not break public API within a released ROS distribution, i.e. no major releases once the ROS distribution is released.

ABI Stability Within a Released ROS Distribution [1.v]/[1.vi]

trajectory_msgs does not contain any C or C++ code and therefore will not affect ABI stability.

Change Control Process [2]

trajectory_msgs follows the recommended guidelines for ROS Core packages in the ROS 2 Developer Guide.

Change Requests [2.i]

This package requires that all changes occur through a pull request.

Contributor Origin [2.ii]

This package uses DCO as its confirmation of contributor origin policy. More information can be found in CONTRIBUTING.

Peer Review Policy [2.iii]

Following the recommended guidelines for ROS Core packages, all pull requests must have at least 1 peer review.

Continuous Integration [2.iv]

All pull requests must pass CI on all tier 1 platforms

Documentation Policy [2.v]

All pull requests must resolve related documentation changes before merging.

Documentation

Feature Documentation [3.i]

trajectory_msgs has a list of provided messages and services. New messages and services require their own documentation in order to be added.

Public API Documentation [3.ii]

trajectory_msgs has embedded API documentation, but it is not currently hosted.

License [3.iii]

The license for trajectory_msgs is Apache 2.0, the type is declared in the package.xml manifest file, and a full copy of the license is in the repository level LICENSE file.

There are no source files that are currently copyrighted in this package so files are not checked for abbreviated license statements.

Testing [4]

trajectory_msgs is a package providing strictly message and service definitions and therefore does not require associated tests and has no coverage or performance requirements.

Linters and Static Analysis [4.v]

trajectory_msgs uses and passes all the standard linters and static analysis tools for its generated C++ and Python code to ensure it follows the ROS 2 Developer Guide.

Results of the nightly linter tests can be found here.

Dependencies [5]

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

trajectory_msgs has the following runtime ROS dependencies, which are at Quality Level 1:

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.

Direct Runtime Non-ROS Dependencies [5.iii]

trajectory_msgs does not have any runtime non-ROS dependencies.

Platform Support [6]

trajectory_msgs supports all of the tier 1 platforms as described in REP-2000, and tests each change against all of them.

Currently nightly results can be seen here:
