Issue 17413: Write with handle_nil underspecified (data-distribution-rtf)
Source: Remedy IT (Mr. Johnny Willemsen, jwillemsen(at)remedy.nl)
Nature: Clarification
Severity: Minor
Summary: For write the DDS spec says:


The special value HANDLE_NIL can be used for the parameter handle. This indicates that the identity of the instance
should be automatically deduced from the instance_data (by means of the key).

The case which is not specified is the case where the handle is HANDLE_NUL, but they key we use hasn't been registered with dds yet, will DDS than return an error, or automatically register a new instance?

While I was reading the DDS spec to look up something unrelated, I remembered that there was this issue (#17413).  In another section of the spec, the supposedly-underspecified item is actually specified.  To address the issue, the point should be clarified in the section for the write() method.


7.1.3.21   WRITER_DATA_LIFECYCLE
[...] data-instances that have been either explicitly registered with the DataWriter
using the register operations (see Section 7.1.2.4.2.5 and Section 7.1.2.4.2.6) or
implicitly by directly writing the data (see Section 7.1.2.4.2.11 and Section 7.1.2.4.2.12).
