Re: [netmod] derived-from-or-self leads to circular import

[Balazs Lengyel]

Hello Bart, A nice solution could be to separate ietf-entity into 2 yang modules (YAMs). One handling only generic entity stuff and another handling sensor related stuff. If  ietf-entity does not include any entity-type specific stuff it does not need to import iana-entity any more. This is how it works with ietf-interfaces and iana-if-type. Ietf-interfaces does not include anything that is if-type specific. Problem solved. regards Balazs On 2016-07-29 14:50, Bogaert, Bart (Nokia - BE) wrote: Hi,   The IETF draft entity model has added the following:         container sensor-data {           when 'derived-from-or-self(../class,                                      "iana-entity", "sensor")' {   We already know that derived-from-or-self actually only has 2 parameters so it is expected to become           container sensor-data {           when 'derived-from-or-self(../class,                                      "iana-entity:sensor")' {   In order to correctly compile (using confdc) we also need to import iana-entity for the identities defined in there.  However this is leading a circular dependency: 1.       Iana-entity imports ietf-entity (to ‘resolve’ entity-physical-class) 2.       Ietf-entity imports iana-entity (to obtain the indentities defined in there)   One way to solve this is to move the definition of entity-physical-class from ietf-entity to iana-entity which would resolve the fact that iana-entity requires an import of ietf-entity (ietf-entity needs to import iana-entity anyhow, so it can also pick the typedef from the same module too).   Whatever solution is chosen, the circular import needs to be resolved (or circular imports should be allowed – after all: what has been imported can be “tracked” removing the need to re-import something that was already imported).   Best regards - Vriendelijke groeten, Bart Bogaert Broadband-Access System Architect Data Contact number +32 3 2408310 (+32 477 673952)   NOKIA Copernicuslaan 50, 2018 Antwerp, Belgium Fortis 220-0002334-42 VAT BE 0404 621 642 Register of Legal Entities Antwerp << This message (including any attachments) contains confidential information intended for a specific individual and purpose, and is protected by law.
