ietf-nntp Re: LIST HEADERS inconsistency issue

[Clive D.W. Feather]

Okay, changes applied on what I think the consensus was:

In 8.6 (HDR extension) add:

    The HDR command may take information from a database rather than
    directly from the articles. If so, the same issues of consistency and
    inconsistency apply as with the OVER extension (Section 8.5) and the
    LIST HEADERS command SHOULD take the same approach as the LIST
    OVERVIEW.FMT command in resolving them.

In 8.6.1.2 (HDR) add:

    If HDR uses a separate database and it is inconsistent for the
    requested header or metadata item, the server MAY return what results
    it can or it MAY respond with the generic 503 response; in the latter
    case, the field MUST NOT appear in the output from LIST HEADERS.

In 8.6.2.2 (LIST HEADERS) delete:

    If the list of available fields is not the same for all articles (for
    example, because the HDR command uses the same database as the OVER
    command and the set of fields being stored has recently changed),
    then the response should indicate the situation for a newly-arrived
    article.
