Certain operations, like removing non-presence containers or modifying list keys, are not considered to be valid from the perspective of the northbound layer. This is because we want to implement a minimum set of northbound configuration callbacks and use them to process all possible configuration changes. The removal of a np-container [1], for example, can be processed by calling the "delete" callback of all of its child nodes (recursion is used for np-container child nodes). Similarly, the modification of a list key can be processed as if the corresponding list entry was removed and readded with updated key values. This strategy saves us the burden of implementing lots of extra configuration callbacks. That said, the nb_operation_is_valid() function shouldn't be used for anything other than checking which callbacks are valid for which YANG nodes. Using it in the nb_candidate_edit() function is inappropriate as we want as much flexibility as possible when editing a candidate configuration. We should allow CLI commands, for example, to remove np-containers (the northbound layer will then figure out which callbacks need to be called when this candidate is committed). Remove the check. [1] We can't do the same for presence containers since they have a "create" callback associated with them. Signed-off-by: Renato Westphal <renato@opensourcerouting.org> |
