| * Notes on deprecation: | |
| * | |
| * A *major* release is a release through which all upgrades must pass | |
| * (e.g., jewel). For example, no pre-jewel server will ever talk to | |
| * a post-jewel server (mon, osd, etc). | |
| * | |
| * For feature bits used *only* on the server-side: | |
| * | |
| * - In the first phase we indicate that a feature is DEPRECATED as of | |
| * a particular release. This is the first major release X (say, | |
| * jewel) that does not depend on its peers advertising the feature. | |
| * That is, it safely assumes its peers all have the feature. We | |
| * indicate this with the DEPRECATED macro. For example, | |
| * | |
| * DEFINE_CEPH_FEATURE_DEPRECATED( 2, 1, MONCLOCKCHECK, JEWEL) | |
| * | |
| * because 10.2.z (jewel) did not care if its peers advertised this | |
| * feature bit. | |
| * | |
| * - In the second phase we stop advertising the the bit and call it | |
| * RETIRED. This can normally be done in the *next* major release | |
| * following the one in which we marked the feature DEPRECATED. In | |
| * the above example, for 12.0.z (luminous) we can say: | |
| * | |
| * DEFINE_CEPH_FEATURE_RETIRED( 2, 1, MONCLOCKCHECK, JEWEL, LUMINOUS) | |
| * | |
| * - The bit can be reused in the first post-luminous release, 13.0.z | |
| * (m). | |
| * | |
| * This ensures that no two versions who have different meanings for | |
| * the bit ever speak to each other. | |
