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

action_msgs Quality Declaration

The package action_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]

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

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]

action_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]

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

Change Control Process [2]

action_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]

Testing [4]

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

Dependencies [5]

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

action_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]

action_msgs does not have any runtime non-ROS dependencies.

Platform Support [6]

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