Hi Prasad, As I and Casey noted in the PR, the obvious way would be to extend the lifecycle grammar to introduce a new rule element. As I noted, this is the path we've already followed with IAM policy, without any notable issue. The schema checking that existing tools may be doing (sometimes just by using XML interfaces, I suspect) reveals a need for processes (contributions to those tools, perhaps reference to different schema when using them?) to allow for more orderly evolution of S3 in the community. From what I understand, haven't you also found that some tool versions took issue with new status code tokens, as well?

I've chosen to convert the 'State' field in the LC-Rule into a tri-state from a boolean i.e. 'Disabled'/'Enabled'/'Purge_Enabled' (instead of having only the first two states) and it has the following advantages: > a) It is non-intrusive i.e. existing users of LC who have no interest in bucket purge need not make any changes to their code > b) It can be easily enabled by interested users without requiring a patch on their SDKs (which allow a pass-through of the Status string). > > Does the community feel that this approach is good or are there any better suggestions? > > Thanks, > K.Prasad > > > > _______________________________________________ > Dev mailing list -- dev@xxxxxxx > To unsubscribe send an email to dev-leave@xxxxxxx -- Matt Benjamin Red Hat, Inc. 315 West Huron Street, Suite 140A Ann Arbor, Michigan 48103 http://www.redhat.com/en/technologies/storage tel. 734-821-5101 fax. 734-769-8938 cel. 734-216-5309 _______________________________________________ Dev mailing list -- dev@xxxxxxx To unsubscribe send an email to dev-leave@xxxxxxx
