JMAP for Sieve Scripts
draft-ietf-jmap-sieve-22

[Ballot comment]
I share the issues Roman mentioned in his comments. Additionally:

        blobId: Id The id of the blob containing the raw octets of the script.

How is this Id specified? Also in "(UTF-8) octets" ? Can it contain control characters?
Similar for other entries that don't specify the type, eg "accountId".


        onSuccessActivateScript: Id (optional)

I read this first as "Id is optional" but after realizing this made no sense, I figured
out that onSuccessActivateScript is optional. Perhaps write it as:

        onSuccessActivateScript (optional): Id

or:

        [optional] onSuccessActivateScript: Id


While I agree that the Security Considerations are those of JMAP and Sieve, I found
that neither of those try to confirm Sieve modifications with some interactive
user (eg imagine it requiring FaceID on my iphone to modify Sieve scripts). This
would harden things a bit but arguably that not this documents problem to solve.

[Ballot comment]
Thank you to Ines Robles for the GENART review.

** Section 1.2.1

      The maximum length, in (UTF-8) octets, allowed for the name of a
      SieveScript.  For compatibility with ManageSieve, this MUST be at
      least 512 (up to 128 Unicode characters).

What’s a “(UTF-8) octet” as opposed to just a “octet”?

** Section 2.1
      For
      compatibility with ManageSieve, servers MUST reject names that
      contain control characters

What is the definition of “control characters”?  Recommend either citing Section 1.6 of RFC5804 or repeating the guidance here.

** Section 2.4
      If the id is either illegal or nonexistent, it MUST be ignored and
      the currently active SieveScript (if any) will remain as such.

Is an “illegal” id the same as “invalid”?  That might be clearer.

** Section 2.6 and 5.  The SieveScript validation would appear to require the serve to parse and validate the provided SieveScript.  Section 5 cites the security considerations of RFC5804 and RFC8620.  The latter has Section 8.4 which discusses the considerations for JSON processing.  Is there an equivalent for a Sieve script (which is not JSON).

(Via drafts-lastcall@iana.org): IESG/Authors/WG Chairs:

IANA has completed its review of draft-ietf-jmap-sieve-16. If any part of this review is inaccurate, please let us know.

IANA understands that, upon approval of this document, there are three actions which we must complete.

First, in the JMAP Capabilities registry in the JSON Meta Application Protocol (JMAP) registry group located at:

https://www.iana.org/assignments/jmap/

a single new registration is to be made as follows:

Capability Name: urn:ietf:params:jmap:sieve
Intended Use: common
Change Controller: IETF
Security and Privacy Considerations: [ RFC-to-be; Section 4 ]
Reference: [ RFC-to-be ]

As this document requests a registration in an Expert Review or Specification Required (see RFC 8126) registry, we have initiated the required Expert Review via a separate request. This review must be completed before the document's IANA state can be changed to "IANA OK."

Second, in the JMAP Data Types registry also in the JSON Meta Application Protocol (JMAP) registry group located at:

https://www.iana.org/assignments/jmap/

a single new registration is to be made as follows:

Type Name: SieveScript
Can Reference Blobs: yes
Can Use for State Change: yes
Capability: urn:ietf:params:jmap:sieve
Reference: [ RFC-to-be ]

As this also requests a registration in an Expert Review or Specification Required (see RFC 8126) registry, we have initiated the required Expert Review via a separate request. This review must be completed before the document's IANA state can be changed to "IANA OK."

Third, in the JMAP Error Codes registry also in the JSON Meta Application Protocol (JMAP) registry group located at:

https://www.iana.org/assignments/jmap/

two new registrations are to be made as follows:

JMAP Error Code: invalidScript
Intended Use: common
CHANGE Controller: IETF
Description: The SieveScript violates the Sieve grammar [RFC5228] and/or one or more extensions mentioned in the script's "require" statement(s) are not supported by the Sieve interpreter.
Reference: [ RFC-to-be; Section 2.2 ]

JMAP Error Code: scriptIsActive
Intended Use: common
CHANGE Controller: IETF
Description: The client tried to destroy the active SieveScript.
Reference: [ RFC-to-be; Section 2.2 ]

As this also requests registrations in an Expert Review or Specification Required (see RFC 8126) registry, we have initiated the required Expert Review via a separate request. This review must be completed before the document's IANA state can be changed to "IANA OK."

We understand that these are the only actions required to be completed upon approval of this document.

NOTE: The actions requested in this document will not be completed until the document has been approved for publication as an RFC. This message is meant only to confirm the list of actions that will be performed.

# Document Shepherd Write-Up for Group Documents

*This version is dated 4 July 2022.*

Thank you for your service as a document shepherd. Among the responsibilities is
answering the questions in this write-up to give helpful context to Last Call
and Internet Engineering Steering Group ([IESG][1]) reviewers, and your
diligence in completing it is appreciated. The full role of the shepherd is
further described in [RFC 4858][2]. You will need the cooperation of the authors
and editors to complete these checks.

Note that some numbered items contain multiple related questions; please be sure
to answer all of them.

## Document History

1. Does the working group (WG) consensus represent the strong concurrence of a
  few individuals, with others being silent, or did it reach broad agreement?

Strong consensus

2. Was there controversy about particular points, or were there decisions where
  the consensus was particularly rough?

No controversy.

3. Has anyone threatened an appeal or otherwise indicated extreme discontent? If
  so, please summarize the areas of conflict in separate email messages to the
  responsible Area Director. (It should be in a separate email because this
  questionnaire is publicly available.)

No

4. For protocol documents, are there existing implementations of the contents of
  the document? Have a significant number of potential implementers indicated
  plans to implement? Are any existing implementations reported somewhere,
  either in the document itself (as [RFC 7942][3] recommends) or elsewhere
  (where)?

The protocol is implemented in production at Fastmail and test implementations
have been done by other JMAP server authors.

## Additional Reviews

5. Do the contents of this document closely interact with technologies in other
  IETF working groups or external organizations, and would it therefore benefit
  from their review? Have those reviews occurred? If yes, describe which
  reviews took place.

The only other group is EXTRA and it's been cross reviewed there

6. Describe how the document meets any required formal expert review criteria,
  such as the MIB Doctor, YANG Doctor, media type, and URI type reviews.

No formal reviews

7. If the document contains a YANG module, has the final version of the module
  been checked with any of the [recommended validation tools][4] for syntax and
  formatting validation? If there are any resulting errors or warnings, what is
  the justification for not fixing them at this time? Does the YANG module
  comply with the Network Management Datastore Architecture (NMDA) as specified
  in [RFC 8342][5]?

No YANG.

8. Describe reviews and automated checks performed to validate sections of the
  final version of the document written in a formal language, such as XML code,
  BNF rules, MIB definitions, CBOR's CDDL, etc.

The JSON snippets were pasted through `jq .`, which caught some issues which
the author has now corrected in a new draft.

## Document Shepherd Checks

9. Based on the shepherd's review of the document, is it their opinion that this
  document is needed, clearly written, complete, correctly designed, and ready
  to be handed off to the responsible Area Director?

Yes, this document is clearly written and complete.

10. Several IETF Areas have assembled [lists of common issues that their
    reviewers encounter][6]. For which areas have such issues been identified
    and addressed? For which does this still need to happen in subsequent
    reviews?

There aren't any common areas likely to affect this outside the JMAP group's
expertise.

11. What type of RFC publication is being requested on the IETF stream ([Best
    Current Practice][12], [Proposed Standard, Internet Standard][13],
    [Informational, Experimental or Historic][14])? Why is this the proper type
    of RFC? Do all Datatracker state attributes correctly reflect this intent?

Proposed Standard, as it extends a proposed standard.  Datatracker reflects that.

12. Have reasonable efforts been made to remind all authors of the intellectual
    property rights (IPR) disclosure obligations described in [BCP 79][7]? To
    the best of your knowledge, have all required disclosures been filed? If
    not, explain why. If yes, summarize any relevant discussion, including links
    to publicly-available messages when applicable.

Yes, the author has been asked, no known IPR.

13. Has each author, editor, and contributor shown their willingness to be
    listed as such? If the total number of authors and editors on the front page
    is greater than five, please provide a justification.

Yes, there's only the one editor, and the acknowledged people are all happy with
being acknowledged too.

14. Document any remaining I-D nits in this document. Simply running the [idnits
    tool][8] is not enough; please review the ["Content Guidelines" on
    authors.ietf.org][15]. (Also note that the current idnits tool generates
    some incorrect warnings; a rewrite is underway.)

There's one nit "looks like a code comment", which looks like a false positive
of the idnits tool.

15. Should any informative references be normative or vice-versa? See the [IESG
    Statement on Normative and Informative References][16].

The references look correct, informative for those which you don't need to know
for implementation, but are mentioned to demonstrate interactions with them in
some examples.

16. List any normative references that are not freely available to anyone. Did
    the community have sufficient access to review any such normative
    references?

All references are to IETF RFCs.

17. Are there any normative downward references (see [RFC 3967][9] and [BCP
    97][10]) that are not already listed in the [DOWNREF registry][17]? If so,
    list them.

No.

18. Are there normative references to documents that are not ready to be
    submitted to the IESG for publication or are otherwise in an unclear state?
    If so, what is the plan for their completion?

There's an informative reference to draft-ietf-jmap-blob, which has since
become RFC9404, however this can easily be fixed during edit.

19. Will publication of this document change the status of any existing RFCs? If
    so, does the Datatracker metadata correctly reflect this and are those RFCs
    listed on the title page, in the abstract, and discussed in the
    introduction? If not, explain why and point to the part of the document
    where the relationship of this document to these other RFCs is discussed.

No RFCs will be changed.

20. Describe the document shepherd's review of the IANA considerations section,
    especially with regard to its consistency with the body of the document.
    Confirm that all aspects of the document requiring IANA assignments are
    associated with the appropriate reservations in IANA registries. Confirm
    that any referenced IANA registries have been clearly identified. Confirm
    that each newly created IANA registry specifies its initial contents,
    allocations procedures, and a reasonable name (see [RFC 8126][11]).

The IANA considerations specify new entries in two registries, and those entries
are fully specified and reasonable.

21. List any new IANA registries that require Designated Expert Review for
    future allocations. Are the instructions to the Designated Expert clear?
    Please include suggestions of designated experts, if appropriate.

There are no new registries.
